Description

Module detection equipment and jointed board for carrying module array

Technical Field

The application relates to a camera module detection technology and an industrial automation technology, in particular to a module detection device and a jointed board for carrying a module array.

Background

At present, the camera module has been widely applied to the field of consumer electronics terminals (such as smart phones, tablet computers, notebook computers, etc.), becomes an indispensable part in the life of people, and has a wide market prospect. The camera module is a small and precise product, and precise processing is required in the production process. In the early stage of the industry, the camera module industry has spent a long term mainly by purchasing a small amount of foreign production equipment and combining a large amount of manpower. And, along with intelligent terminal's popularization, the module industry of making a video recording has come a high-speed development stage. In this period, small module factories with small quantity and immature technology are gradually eliminated, and some module factories with mature technology and large quantity are left. The module factories digest a large amount of module orders in domestic markets, the production volume of the orders can reach the level of millions or even tens of millions, the defect of excessive dependence on manpower production is more and more obvious when the order reaches the level, and the semi-automatic or automatic production of mechanical equipment is a necessary trend.

The semi-automatic or automatic production is realized by first needing the support of corresponding production equipment, and the equipment can be obtained by two modes of self-research and external purchase. The externally purchased equipment is expensive on one hand, cannot completely meet the production requirements of purchasers due to production reasons (such as confidentiality of some production processes) and the like on the other hand, and the self-developed equipment can be designed according to the production requirements. The improvement of the production efficiency is one of the important pursuits of the major module factories.

As mentioned above, the production level of the module factory is so large that the module factory puts most of the effort on how to realize high-efficiency production. When high-efficiency production is pursued, the integrated road is easily reached, namely, all links of production are integrated into the same equipment. The multifunctional integration enables the equipment to complete all work, and realizes integration in time and space to a great extent, so that the production efficiency can be effectively improved theoretically. However, in order to integrate a plurality of functions, it is necessary to achieve a relatively suitable state by matching and mutually compromising the functions in terms of structural arrangement and process design. Therefore, which functions are suitable for being integrated together, and how to mutually cooperate and compromise the functions, is one of the major problems faced by the design of the camera module production equipment.

The application mainly relates to a camera module detection device. The module detection of making a video recording is an indispensable ring in the module production of making a video recording. The camera module inspection apparatus (hereinafter, simply referred to as module inspection apparatus) also faces a significant problem of how to improve the production efficiency. Early modular inspection equipment typically had a dedicated inspection equipment for each test session (i.e., each test). Under the development idea of integration, more and more module detection equipment integrates a plurality of testing links, and some module detection equipment can integrate all testing links even, namely, all tests are completed by using single equipment. On the other hand, for improving production efficiency, some module test equipment have adopted array detection scheme, and a target corresponds to the module array of making a video recording that a plurality of modules of making a video recording are constituteed promptly, and this test link can once only test a plurality of modules of making a video recording like this to show promotion production efficiency. Moreover, some module test equipment still further will make a video recording the unloading link integration of module in module test equipment to further improve the integrated level of equipment.

Although the prior art has adopted many techniques to improve the module inspection apparatus, the existing module inspection apparatus has many disadvantages to be further improved.

For array detection, the camera module array needs to be accessed into the test equipment before testing. And the stitch of the module of making a video recording is intensive, if will make a video recording a plurality of modules of arranging with the array and insert the test equipment simultaneously, the requirement to inserting the precision is extremely high. Based on this, the applicant has proposed a splicing scheme based on an adapter plate. In the scheme, the camera module is firstly plugged on the adapter plate, and the dense pin array is led to the relatively sparse pin, jack or contact array by the routing on the PCB of the adapter plate. Thus, the dense pin array of the camera module is converted into a larger size and spaced pin, jack or contact array on the interposer. And then a plurality of adapter plates carrying the camera module are installed on one jointed board, and then pins, jacks or contact arrays of the whole jointed board are electrically connected with the test equipment, so that the power-on test of the camera module array can be realized. This scheme can reduce the grafting degree of difficulty of making a video recording module array effectively, promotes production efficiency. However, in actual mass production, the panels are frequently inserted or contacted (a certain pressure is required to press the panels to avoid poor contact) and the surface of the panels may be deformed, for example, the panels may be bent. After bending occurs, the jacks or contact arrays of the jointed boards (namely, the jack arrays on the adapter board) are difficult to align with the probe arrays of the module testing equipment, so that the failure rate of the module testing equipment is increased, and the improvement of the production efficiency is not facilitated.

On the other hand, in the existing inspection equipment, a probe array driven by a cylinder or a motor is generally used to electrically connect the equipment with the panel (or module). Such probe arrays and their drive mechanisms tend to be heavy and if a test module containing such probe arrays is mounted on a turntable or similar movable platform, the turntable or other mounting platform may be unstable, resulting in inaccurate test results and even difficulty in completing the test project. Therefore, in the existing highly compact integrated detection equipment, only the material carrying platform can move to different stations along with the turntable (or other movable platforms) to perform detection, and the probe array for realizing electric connection and the driving mechanism thereof can only be arranged on a stable fixed platform (such as the ground). Therefore, when the material carrying platform is changed to a station, the jointed boards or the modules are inserted or contacted again by the probe array, more abrasion is brought, and the work efficiency is not improved.

Moreover, some module test equipment has still tried to peg graft the module of making a video recording one by one on module test equipment. The scheme can basically ensure that dislocation is avoided, and the problem of failure rate improvement caused by bending of the jointed boards can be avoided. However, the process of placing the camera modules at the detection positions of the detection equipment one by one is time-consuming, and the production efficiency of the whole detection equipment is greatly influenced.

Furthermore, in the integrated module detection equipment, each functional module is densely arranged in a compact space. Theoretically, this helps to increase the yield per unit area. However, this design also results in inconvenient maintenance of the device. When equipment failure, the maintainer will spend more time just can make module check out test set resume production. Therefore, if considering the production interruption time due to the failure, the yield per unit area of the entire excessively integrated module inspection apparatus may not be optimal.

In summary, there is a need for a solution for a module inspection apparatus (an inspection apparatus including a camera module or other similar electronic device function modules) that can overcome the above-mentioned drawbacks.

According to an embodiment of the present application, an integrated camera module automatic test equipment is provided, which includes a rotary test mechanism and a plurality of target modules surrounding the rotary test mechanism. Where each reticle module may correspond to a workstation. The rotary testing mechanism can be provided with a plurality of testing modules, and in the rotating process, each testing module can sequentially reach each station to be combined with each target module arranged around the rotary testing mechanism to complete each test. Further, fig. 1 illustrates a perspective view of a rotary testing mechanism 1000 of an embodiment of the present application, according to an embodiment of the present application. Referring to fig. 1, in the present embodiment, the rotary testing mechanism 1000 includes a turntable 200, a plurality of racks 300, and a plurality of test modules 100. The plurality of brackets 300 are disposed at the peripheral region of the turntable 200, one detection module 100 is mounted on each bracket 300, and the front surface 101 of each detection module 100 is vertical and disposed outward in the detection state, that is, the front surface 101 of the detection module 100 faces the target module in the detection state. In this embodiment, the detection module 100 includes a material stage. Fig. 2 shows a material stage 110 in one embodiment of the present application. Referring to fig. 2, in the present embodiment, the material carrying platform 110 has a bearing surface 111 and a lateral plugging mechanism 114, wherein the bearing surface 111 is adapted to bear against a back surface of a jigsaw puzzle 500 (refer to fig. 3 and 4 in combination) carrying a camera module array, and the lateral plugging mechanism 114 is laterally movable relative to the bearing surface 111 and adapted to be plugged into an electrical interface disposed on a side surface of the jigsaw puzzle 500. The target module is adapted to provide a test light source and a target (e.g., a test pattern) for the panel.

Further, referring to fig. 1 and fig. 2 in combination, in an embodiment of the present application, in each material carrying platform 110, a positioning column 112 or a positioning groove (the positioning groove is not shown in fig. 2) is disposed on the bearing surface 111, and is adapted to be inserted into the positioning groove or the positioning column disposed on the back surface of the jigsaw 500. The axis of the positioning post or the positioning slot may be perpendicular to the bearing surface 111. Through the bearing surface 111 and the positioning column 112, and the fixing function of the lateral plugging mechanism 114, the jointed board 500 can be well fixed on the material carrying platform 110.

Further, still referring to fig. 1, in one embodiment of the present application, a central receiving case 400 may be provided at the center of the turntable 200, and the top of the central receiving case 400 may have a through hole to allow a cable to pass through. Cables drawn out from the back (or other portions) of the respective detection modules 100 may pass through the through-holes and be received in the central receiving case 400.

Further, fig. 3 is a perspective view of a puzzle 500 for carrying an array of camera modules according to an embodiment of the present invention. Referring to fig. 3, in this embodiment, the panels 500 may include a rectangular parallelepiped carrier 510 and a cover (not shown) adapted to the rectangular parallelepiped carrier. The carrier 510 may have a plurality of module mounting slots 511 (the modules herein refer to camera modules, and are not described in detail below). The mounting slots 511 may be arranged in an array, and the mounting slots 511 may have conductive points therein for electrically connecting with the connectors 610 of the module 600. Meanwhile, the surface of the mounting groove 511 facing the module 600 may further have an opening, and the opening may provide a negative pressure for adsorbing and leveling the circuit board of the module. The cover body has a corresponding lens opening and a module fixing structure at a position corresponding to each mounting groove 511, and the lens opening corresponds to the position of the lens 620 of the module 600 received in the mounting groove 511. The module fixing structure is located on the inner side of the cover body (i.e. the side facing the carrier). Specifically, the module fixing structure may be located at the periphery of the lens opening, and it may be an elastic structure having a certain amount of expansion and contraction, and may apply a slight pressure to the module 600 so as to play a role of fixing the module 600. In this embodiment, the hardness of the material of the module fixing structure (i.e., the elastic structure) and the module bearing surface of the carrier 510 are both less than that of the module 600, so as to prevent the module 600 from being damaged. The module fixing structure will be further described with reference to other embodiments, which will not be described herein again. Further, in this embodiment, the panels 500 are picked, placed and fixed in a loading and unloading mechanism independent of the rotary testing mechanism 1000. That is, the material interaction between the rotary testing mechanism 1000 and the loading and unloading mechanism is in units of the jigsaw 500, not in units of independent modules. In this embodiment, one side of the carrier 510 may have an electrical interface 520, and the electrical interface 520 may be a USB interface. The USB interface has a plurality ofly, arranges in array mode. In each of the mounting slots 511, a conducting point (usually an array of conducting points) electrically connected to the module connector 610 can be connected to the USB interface through a line inside the carrier 510. In this embodiment, 1 USB interface may correspond to data input/output ports of 2 modules (or more modules, as long as the data transmission rate meets the requirement). The jointed board realizes the electric connection and information interaction with the detection equipment through the USB port. The detection module of the automatic detection device can be provided with an insertion opening corresponding to the USB interface, and the detection module and the insertion opening can be electrically connected through a plug-in structure. And the USB interface is arranged on the side surface of the jointed board, and when the USB interface is electrically connected with the side surface of the jointed board, the stress direction of the jointed board is parallel to the jointed board bearing surface of the detection module, so that the deformation of the surface (such as the bottom surface) of the jointed board is favorably avoided, and the detection accuracy of the camera module is guaranteed. In contrast, in a comparative example (i.e., a conventional board splicing scheme), the detection module is directly plugged into the board via the probe array (or probe socket), i.e., the probe array is directly plugged into the corresponding probe socket (or probe socket) disposed on the bottom surface of the board. In this comparative example, since the force direction of the jointed board is perpendicular to the bottom surface of the jointed board, the jointed board is likely to deform after repeated use, for example, the bottom surface of the jointed board is uneven. Such unevenness adversely affects the detection accuracy. In addition, because the unevenness is not easy to detect, in the automatic operation process of the equipment, the detection module is damaged due to plugging failure, the production line is stopped, and the production efficiency is seriously influenced. Therefore, the lateral USB interface design of the embodiment can effectively avoid various problems caused by deformation of the surface (such as the bottom surface) of the jointed board, can obviously improve the detection accuracy, reduce the failure rate and improve the production efficiency.

It should be noted that the side interface of the present application is not limited to the USB interface, and in other embodiments, other types of electrical interfaces may be used instead, as long as the electrical interfaces can meet the data transmission rate requirements of all the camera modules on the panel.

Further, fig. 4 is a perspective view of a puzzle for carrying a camera module array according to another embodiment of the present invention. Referring to fig. 4, in this embodiment, a module fixing block 530 is added to the panels to serve as a transfer member for connecting the module 600 and the carrier 510. The carrier 510 has a plurality of mounting slots 511 arranged in an array, and the module fixing block 530 is adapted to the mounting slots 511 in shape. For example, when the mounting groove 511 has a rectangular parallelepiped shape, the module fixing block 530 also has a rectangular parallelepiped shape. The module fixing block 530 also has a groove 531 at the center thereof adapted to mount a camera module. Also, each module fixing block 530 has a plurality of first contacts and a plurality of second contacts. The first contacts are disposed at a carrier contact surface (i.e., a surface that contacts the carrier) of the module fixing block 530 and are adapted to be electrically connected with the contacts of the carrier 510. The second contacts are disposed in the grooves 531 of the module fixing block 530, which are adapted to be connected with the connectors 610 of the module 600. The shape of the groove 531 of the module fixing block 630 may be adapted to the outer shape of the module 600 so as to better fix the module 600. Further, the contact surface of the module fixing block 530 and the circuit board of the module 600 may be provided with an opening, and the opening may provide a negative pressure so as to flatten the circuit board of the module and better fix the circuit board of the module. In this embodiment, panel 500 may also have a cover (not shown) that fits over carrier 510. The specific structure of the cover body can refer to the description of the previous embodiment, and is not described herein again. In this embodiment, the module fixing block 530 may serve as a relay for connecting the electrical signals of the module 600 to the carrier, and then leading the electrical signals to the USB interface (or other types of electrical interfaces disposed on the side of the carrier) through the wires inside the carrier 510. The scheme of this embodiment can make the makeup can the camera module of multiple different models of adaptation better. For example, to the module of making a video recording of unidimensional not, only need change with the module fixed block that corresponds the module adaptation, can use same carrier to carry on, and then accomplish each item detection item of this module. Specifically, the mounting groove of the carrier can be designed into a standard structure, and the peripheral structure of a single module fixing block can also be a standard structure. Meanwhile, the recess of the single module fixing block (i.e., the receiving space in the module fixing block) is designed according to the type of the module. Like this, when the module type of production is changed, only need to change the single module fixed block that corresponds the model can, and need not follow other interrelated parts, reduce the equipment and cut the part that the in-process need be changed, reduce the time of cutting the machine by a wide margin. Here, a cutting machine is a common vocabulary in the art. In the actual production process, for one piece of equipment, every time a new model of product needs to be produced (or another model of product needs to be replaced for production), the clamp, the target position and the like of the equipment may need to be replaced, and the software data and the position information may need to be reset to adapt to the production of a new model of module. For example, if a square module is produced previously and a round module is produced by switching, the matching items are adjusted or replaced. This switching process is a switch-off process.

Further, still referring to fig. 2, in an embodiment of the present application, the material stage 110 further includes a clamping mechanism 113, where the clamping mechanism 113 includes two

clamping plates

113a and 113b respectively disposed on two sides of the material stage 110; wherein the top of each of the

clamping plates

113a, 113b is provided with a

side bar

113c, 113d, and the side bars 113c, 113d are adapted to bear against the edge area of the top surface of the jointed boards (here, the top surface is the front surface of the jointed boards) and press the jointed boards against the material carrier 110. Referring to fig. 2, in the present embodiment, the edge strips 113c and 113d may be integrally formed with the main body portions of the

clamping plates

113a and 113b, or may be formed separately and then fixed on the top portions of the

clamping plates

113a and 113 b. Further, fig. 5a shows a schematic view of one embodiment of the present application in which clamping mechanism 113 is used to clamp panel 500. Fig. 5b is a schematic view of plate alignment 500 pressed against material carrier 110 by clamping mechanism 113 according to an embodiment of the present application. Referring to fig. 5a and 5b, in this embodiment, the clamping mechanism 113 can clamp the jointed board 500 from the side to place it on the bearing surface 111 of the material carrying platform 110, and then press the top surface of the jointed board 500 through the edge bars 113c and 113d, so that the jointed board is tightly pressed between the edge bars and the bearing surface 111. In this embodiment, because fixture 113 has the strake, can rely on the strake to fix the makeup to the pressure that the makeup top surface (front) was applyed to the strake to can reduce the pressure that the clamp plate was applyed from both sides to the makeup, avoid the makeup to warp because of the extrusion that comes from both sides. FIG. 5c is a schematic view showing the direction of force applied by the edge strip to the panels in one embodiment of the present application. Referring to fig. 5c, it can be seen that the top (i.e., front) surface of the panels is pressed downwardly (as indicated by the arrows) so that the panels can be compressed between the clamping mechanism and the bearing surface. At this point, the lateral pressure in the direction of the arrows in fig. 5a can be reduced or eliminated, so that deformation of the panels due to compression from both sides is avoided. Further still referring to fig. 2, the lateral attachment mechanism is located on a first side of the material carrier, and the two clamping plates are located on second and third sides of the material carrier that intersect (e.g., are perpendicular to) the first side. In one embodiment, clamping mechanism 113 may be configured to move panel 500 only to a small extent or not to move panel 500, which may minimize or avoid squeezing panel 500 from both sides. With this design, panels 500 can be moved by other transport mechanisms (e.g., suction cup mechanisms that can move along rails) over long distances during loading and unloading, and moved into and out of the material carrier.

Further, still referring to fig. 2, in one embodiment of the present application, for the clamping plate, the lower surface of the edge strip 113c has a positioning post 113e matched with the jointed plate. The positioning post 113e may be in the shape of a projection, but may also be in the shape of a cylinder. Correspondingly, the edge region of the top (i.e. front) face of the panels can have corresponding positioning grooves. Therefore, the positioning columns on the lower surfaces of the side strips are matched with the positioning grooves on the top surfaces of the jointed boards, so that the jointed boards are better fixed on the material carrying platform, and the lateral inserting mechanisms (such as the lateral inserting mechanism with the USB interface) are inserted into the jointed boards from the side surfaces.

Further, in another embodiment of the present application, the positioning grooves on the edge regions of the top (i.e. front) surfaces of the panels can be replaced by positioning posts, and the lower surfaces of the side strips of the clamping plate can be provided with corresponding positioning grooves to match with the positioning posts. Furthermore, the positioning columns on the top surfaces of the jointed boards can be matched with the positioning grooves on the bottom surfaces (namely the back surfaces) of the jointed boards, so that the jointed boards can be stacked conveniently, and the jointed boards can be transported more conveniently. As described above, the positioning groove on the bottom surface of the jointed board can also be matched with the positioning column arranged on the bearing surface of the material carrying platform, so as to help fix the jointed board on the material carrying platform to complete subsequent processes (for example, to complete various detections on materials).

Further, still referring to fig. 1, in an embodiment of the present application, the detection module may be turned 90 degrees with respect to the bracket, so that the detection module may be switched between a horizontal posture and a vertical posture. Further, the automatic detection equipment can be provided with a plurality of test stations and at least one loading and unloading station. Wherein each target module corresponds to a test station. The automatic detection equipment can further comprise a feeding and discharging mechanism, wherein the feeding and discharging mechanism is suitable for taking the jointed boards placed in the horizontal posture, moving the jointed boards to the detection module in the horizontal posture and placing the jointed boards to the bearing surface of the detection module in the horizontal posture. In the embodiment, the design can be realized by decomposing the actions of feeding and discharging the jointed boards and transferring the overturning actions to the detection module end, so that the mechanical arm (or other mechanisms for transferring the jointed boards) for feeding and discharging the jointed boards does not need to have the overturning function, and the complexity of the mechanical arm is further reduced. During the transportation process, the jointed boards are usually horizontally placed. After the action is decomposed, the jointed boards can be kept in a horizontal state, the feeding and discharging time does not need to be additionally occupied due to the overturning action, and the overturning action of the detection module can be carried out simultaneously with the movement of the jointed boards, so that the production efficiency is favorably improved. On the other hand, the complexity of the mechanical arm for loading and unloading the jointed boards is reduced, and particularly the moving freedom degree required by the mechanical arm is reduced, so that the space occupied by the moving range is reduced (for example, a multi-joint mechanical arm capable of realizing overturning usually needs to occupy a larger moving space, and the mechanical arm with a simpler structure can be used for loading and unloading the jointed boards after the freedom degree of overturning is reduced). Like this, automated inspection equipment need not reserve very big space for dodging the action scope of unloading mechanism on the makeup to help making check out test set compacter, promote unit area output rate.

Further, in an embodiment of the present application, the detection module may include a flipping cylinder (where the flipping cylinder is a cylinder for implementing a flipping function), and the flipping cylinder may drive the detection module to flip 90 degrees relative to the bracket. The overturning cylinder can also be replaced by an overturning motor.

Further, still referring to fig. 1, in an embodiment of the present application, the bracket may include two pillars, the detection module is mounted between the two pillars, and each pillar is mechanically connected to the detection module through a bearing. The design can enable the automatic detection equipment to achieve the technical effects of easy disassembly and easy maintenance. Specifically, in this embodiment, the detection module is disposed in the peripheral region of the turntable, and when a certain detection module fails, the detection module can be conveniently detached by only opening the two bearings and pulling out the cable plug on the back (or other positions) of the detection module, and then the detection module is replaced with a new one, so as to quickly recover the operation of the detection device. Therefore, the scheme of the embodiment reduces the fault interruption time, and further improves the production efficiency. Particularly, in a large-scale mass production (for example, mass production of tens of millions of scales), reducing the fault interruption time is very practical to improve the production efficiency.

Further, in one embodiment of the present application, the rotary cylinder or the rotary motor is adapted to drive the detection module to rotate reciprocally within a preset angle range. The detection module or the bracket can also be provided with a limiting structure, so that the rotation of the detection module relative to the bracket does not exceed a preset angle range. The preset angle can be 90 degrees, and can be set to be other angles according to actual conditions.

Further, fig. 6 is a schematic diagram of a parallel production line formed by combining an automatic detection apparatus 1000 and a modular loading and unloading apparatus 2000 according to an embodiment of the present disclosure. Referring to fig. 6, in the embodiment, one modular loading and unloading apparatus 2000 may correspond to a plurality of automatic detection apparatuses 1000 (of course, a plurality of modular loading and unloading apparatuses may correspond to a plurality of detection apparatuses). The module loading and unloading device 2000 can be used for carrying the camera module into the jointed board 500 and taking out the detected module from the jointed board 500. In this embodiment, the loading capacity of the panels 500 of the modular loading and unloading apparatus 2000 (i.e., filling all the mounting slots of the panels with a plurality of modules) may be equal to or higher than that of the automatic inspection apparatus 1000 associated therewith, thereby preventing the inspection apparatus from waiting for loading. Therefore, the time for detecting the module by the detection equipment only has two times of detection time and jointed board replacement time, and the time for the module to load and unload one by one is not available (the jointed board replacement time is far less than the time for the module to load and unload one by one), so that the time for the module to complete various detections can be greatly reduced. Referring to fig. 6, in the present embodiment, the modular loading and unloading apparatus can provide a plurality of stations for outputting the panels, so as to transmit the panels to a plurality of automatic inspection apparatuses in parallel, thereby enabling the production lines to be parallel.

Fig. 7 is a schematic diagram of a serial production line formed by combining an automatic inspection apparatus 1000 and a modular loading and unloading apparatus 2000 according to an embodiment of the present disclosure. Referring to fig. 7, in this embodiment, the modular loading and unloading apparatus 2000 has a single station for outputting the panels 500, the panels 500 outputted from the station can be transported to a plurality of stations of the automatic inspection apparatus 1000 by a conveyor belt or a guide rail, and then the robot (or other mechanism) is used to mount the panels to the inspection modules corresponding to the loading and unloading stations of the automatic inspection apparatus. In this embodiment, the module loading and unloading device can form a serial production line with a plurality of automatic detection devices.

It is worth mentioning that the automatic detection equipment can share the performance results of the modules at different positions of the detection data and the jointed board in real time for the module feeding and discharging equipment after detecting the performance of the module, the feeding and discharging equipment receives the jointed board after detecting, and can directly feed and discharge the modules at different positions according to the detection results according to the matching of the preset position information and the detection result information without re-identifying each module, and the modules can be taken and placed one by one according to the reserved space position information. The detection data may be individual detection data of detection items such as DCC and AFC, good/defective classification results, and defect type information. The defect type information may be, for example, a defective dot defect, a failure to open a pattern defect, or the like.

Further, in an embodiment of the present application, in the automatic detection device, each detection module may have an AFC detection function, a DCC detection function, and an OTP burning function. Still referring to fig. 1, the OTP burning unit can be directly fabricated on the detection module. And the AFC detection function and the DCC detection function need to be realized by matching with corresponding target modules. Based on the carousel of this embodiment, can rotate every detection module in proper order to the respective mark board module department that corresponds of AFC detection function and DCC detection function to realize AFC and DCC and detect. In fig. 1, the number of the detection modules is four, but the present application is not limited to this number. For example, the number of detection modules arranged along the periphery of the turntable may be five, six, etc.

Further, still referring to fig. 1, in one embodiment of the present application, the turntable is disposed on a horizontal base having a flat surface, the base is disposed on a base frame, and four legs of the base frame can be placed on a placement surface such as a floor. The pedestal adjusts the horizontal state of the upper surface of the base platform through the height adjusting devices positioned at the four feet, so that the flatness of the turntable can be ensured under the qualified installation condition. In other words, as the stations on the carousel rotate, the height variation in the Z-axis (i.e., vertical) direction is minimal (i.e., within an error tolerance). As shown in fig. 1, in this embodiment, the turntable has four brackets, and the four brackets are respectively disposed at the trimming positions of the turntable. In particular, in the embodiment, the trimming position of the turntable is provided with four trimming grooves, and two sides of each trimming groove are respectively provided with one pillar of the bracket. The support may support the detection module at a height above the turntable. The upper end of the support can be provided with an opening, the opening of the support on one side of the detection module can be provided with a rotating bearing, and the opening of the other side of the detection module is provided with a turnover motor. The overturning motor is connected with the detection module and drives the detection module to rotate around the rotating bearing, so that the material carrying platform (which can be used for fixing the jointed board and is electrically connected with the jointed board) can be positioned at different angles. Furthermore, the overturning range can be 0-90 degrees through the limiting structure, so that the horizontal state and the vertical state are two stable states, and the loading and unloading of the jointed boards and various tests can be conveniently carried out. Further, in another embodiment, the rotation angle can be set through a program, and the rotation angle is matched with the limiting structure to form a double-insurance or double-fool-proof mechanism, so that the device can be prevented from being damaged greatly due to the problem of the rotation angle when the program fails.

Further, fig. 8 illustrates a schematic bottom view of cover 700 of a panel assembly in an embodiment of the present application. The cover 700 has a plurality of module fitting sites 710 arranged in an array, and each module fitting site 710 fits one camera module 600. For ease of understanding, in fig. 8, the partial module fitting bit 710a does not show the module fixing structure 711, and the partial module fitting bit 710b shows the module fixing structure 711 and the image pickup module 600. The camera module 600 includes a module main body 611, a module connector 610, and a flexible connection pad 612. The module fixing structure 711 is used to press the module body 611 and the module connector 610, so that the camera module 600 is fixed in the module mounting position of the carrier of the puzzle. Further, fig. 9 is a schematic cross-sectional view illustrating a positional relationship between the module fixing structure 711 and the module connector 610 according to an embodiment of the present application. Fig. 10 shows a cross-sectional view of a module securing structure 711 pressing against a module connector 610 according to an embodiment of the present application. Referring to fig. 9 and 10, in the present embodiment, the module fixing structure 711 includes a movable pressing plate 712, a guiding post or a positioning screw 714 fixed on the top plate 713 (i.e., the top plate of the cover 700), and a spring 715, where the spring 715 is sleeved outside the guiding post or the positioning screw 714, and one end of the spring 715 is fixed on the top plate 713, and the other end is connected to the movable pressing plate 712. The movable platen 712 has a through hole 716, and when the top plate 713 is pressed down, a guide post or a set screw 714 passes through the through hole 716. At this point, movable platen 712 also presses down on top plate 713, thereby applying downward pressure to module connector 610, thereby securing module connector 610 and securely contacting module connector 610 with the contact array of the panel (or the contact array of the module retention block) for electrical connection. Meanwhile, the assembly formed by the movable pressing plate 712 and the spring 715 has elasticity, so that the damage of the camera module caused by overlarge stress can be avoided. The module fixing structure 711 fitted with the module main body 611 is similar to that of fig. 9 and 10, i.e., a structure consistent with the scheme shown in fig. 9 and 10 may be employed. It is to be noted that, with the module fixing structure 711 fitted to the module body 611, a light-passing hole (not shown in fig. 9 and 10) may be provided at a corresponding position of the top plate 713 and the movable platen 712, so that the lens of the module body 611 can be detected through the light-passing hole.

Further, in other embodiments of the present application, an identification pattern, such as a two-dimensional code, may be provided on a single module or on a side of each module mounting location of a tile. Like this, through discernment two-dimensional code, can type in the detection information of module to classification when the module unloading is categorised. For example, when the detected jigsaw is unloaded from the module, the module in the jigsaw can be sorted and placed according to the identified detection information. For example, defective products may be rejected. For another example, the modules may be classified according to their imaging quality.

It should be noted that the present application is not limited to a rotary integrated detection device. For example, for integrated detection equipment with linear detection stations, and single detection equipment special for a single detection link, a lateral jointed board electrical interface can be configured. After the lateral jointed board electrical interface is adopted, the stress direction of the jointed board is parallel to the jointed board bearing surface of the detection module for the electrical connection action of the feeding and the discharging of the jointed board, so that the deformation of the surface (such as the bottom surface) of the jointed board can be favorably avoided, and the detection accuracy of the camera module is guaranteed. Meanwhile, the failure rate of equipment is reduced, and the production efficiency is improved.

The scheme of this application also can be applicable to with the module similar other electronic equipment function module of making a video recording. The electronic device may be any kind of consumer electronics terminal device, such as a smart phone, a tablet computer, a notebook computer, etc. The electronic equipment function module is a module which can be arranged in the electronic equipment to complete a certain specific function of the electronic equipment. For example, the camera module, the structured light projection module, the TOF projection module (where TOF is called Time of Flight), the fingerprint identification module, and so on. These modules are generally small in size and are not conveniently transported one by one in the production line, and are usually loaded in batches using trays (or called product boxes) and then transported in the production line in units of whole trays. Also, these modules typically require connectors, which typically have a relatively dense array of contacts, for data exchange with the motherboard of the electronic device. Before leaving the factory, the modules are usually subjected to power-on factory inspection to test the product performance and eliminate defective products.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and are not limited. Although the present invention has been described in detail with reference to the embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
