Description

Transmitter and test handler including transmitter

technical field

The present invention is an invention related to a transmitter and a test handler including the transmitter.

Background technique

Generally, electronic components are circulated in the market after undergoing tests such as durability and defect detection. In order to test such electronic components, a tester for testing the electrically connected electronic components and a test handler for electrically connecting the electronic components to the tester are required.

The test handler uses a test tray that can be transported at one time in a state where a plurality of electronic components are loaded in a matrix in order to increase the test throughput. The electronic components are electrically connected to a test socket in a state of being loaded on the test tray to perform a test.

Electronic components to be tested are in a state of being loaded on a customer tray. The purpose of the customer tray is to load and store electronic components. The untested electronic components thus loaded on the customer tray are transferred to the test tray, or the tested electronic components loaded on the test tray are loaded on the customer tray.

Generally, in order to independently load and arrange a plurality of electronic components in the customer tray, a plurality of grooves are arranged. When multiple electronic components are loaded on a customer tray, deviation from the groove may occur. The phenomenon of deviation from the groove refers to the phenomenon that some of the electronic components are not completely placed in the groove on the customer's pallet, and some of them rest on the outside of the edge of the groove, etc., and cannot be placed normally.

When the electronic components are conveyed to the customer tray in a state deviated from the grooves, there is a problem that the electronic components are broken while the customer tray is being conveyed. In addition, there is a problem that the electronic components that deviate from the grooves cannot be handled normally when they are held in order to transfer them to the test tray. When the electronic components are transported to the test tray in a state where the electronic components are not normally held, cracks will appear in the electronic components, the terminals of the electronic components will be damaged, and problems in the identification of the electronic components will also occur.

In order to prevent the deviation of the electronic components from the groove, the existing conveyor is manufactured with a vibration motor that applies vibration to the customer tray, so that the electronic components placed on the customer tray are completely placed in the groove. Such vibrating motors are fixed on the setting plate of the conveyor to apply vibrations to the setting plate, and the vibrations applied to the setting plate can vibrate the customer tray indirectly. In addition, existing vibration motors have the problem that the deviation of electronic components from the groove cannot be completely solved only by the vibration force applied to the setting plate. In order to improve such a vibrating force, when the size of the vibrating motor is increased in order to increase the size of the vibrating motor, there is a problem that the use of space is reduced, and the fixing force of the vibrating motor and the installation plate is weakened due to the increase in the weight of the vibrating motor. In addition, in order to provide a high-performance vibration motor capable of increasing vibration force without increasing the size of the vibration motor, there is a problem of consuming a large amount of cost.

Hereinafter, specific features of the test handler 1 according to an embodiment of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a test handler 1 according to an embodiment of the present invention can test electronic components D manufactured through a certain manufacturing process, classify them according to test results, and load them into customer trays CT. Such a test handler 1 connects a plurality of electronic components D to a tester T, so that the electronic components D can be tested. Such a test handler 1 may include a test tray TT, a load picker LH, a first sorter STa, a second sorter STb, a sorter SH and an unloader UH, a conveyor 10 and a setter 20 .

The test tray TT can move cyclically on the circulation path C passing through the loading position LP, the testing position TP and the unloading position UP in sequence. The load pick and place LH can load the electronic components D loaded on the customer tray CT1 onto the carrier plate provided at the loading position LP.

The sorting and placing SH can load the plurality of electronic components D loaded on the test tray TT provided at the unloading position UP to the first sorting table STa and the second sorting table STb. Such a pick-and-place SH can be named a sorter. Such sorting and placing SH is configured to be movable in the x-axis direction (for example, left and right directions) as shown in FIG. 1 .

The unloading, picking and placing UH can move the plurality of electronic components D loaded on the sorting tables STa, STb to the empty customer tray CT2, and then load them on the empty customer tray CT2. Such an unloading pick-and-place UH can be named as an unloader. Such a customer tray CT loaded with a plurality of electronic components D can be supplied to the conveyor 10 .

Referring to Fig. 2 again, the conveyor 10 can provide vibratory force to the customer tray CT, and normally install the electronic components D deviated from the groove on the customer tray CT. Such a conveyor 10 may include a vibrating module 11, a lifting module 12 and a controller 13.

The vibration module 11 can directly/indirectly provide vibration force to the customer tray CT loaded with the electronic components D. Such a vibrating module 11 may be configured to be liftable relative to the lifting module 12 . For example, the front side of the vibration module 11 is movably connected to the lifting module 12, and can move up and down relative to the lifting module 12. Such a vibration module 11 may include a vibration transmitting body 100, a setting plate 200, and a vibration motor assembly 300.

Referring again to Figures 3 and 4, the upper surface of the vibratory transport body 100 provides a mounting surface on which customer trays CT can be mounted. Such a vibration transmission body 100 can transmit the vibration generated on the installation plate 200 to the customer tray CT mounted on the installation surface. Such a vibration transmission body 100 is configured to be detachable from the installation plate 200 .

For example, when the vibration transmitting body 100 vibrates, at least a part thereof may be separated from the setting plate 200 . As an example in more detail, the customer tray CT may be vibrated due to the operation of vibrating at least a part of the transport body 100 to separate from the setting plate 200 . The plurality of electronic components D loaded on the customer tray CT may vibrate due to the vibration of the customer tray CT. The electronic component D deviated from the groove can be normally mounted on the customer tray CT due to the vibration of the electronic component D. Such a vibration transmission body 100 may be installed between the customer tray CT and the installation plate 200 .

Such installation grooves 211 can prevent the vibration transmission body 100 from moving arbitrarily in the horizontal direction relative to the installation plate 200 . For example, even if vibration is applied to the vibration transmission body 100, the position in the horizontal direction of the vibration transmission body 100 can be maintained.

The opening hole 212 may expose at least a part of the vibration transmission body 100 installed in the installation groove 211 to the outside. For example, when viewing the lower side of the setting plate 200, a predetermined area of the lower surface of the vibration transmitting body 100 may be exposed. In other words, when the vibrating transmission body 100 and the setting plate 200 are relatively projected upward and downward, the predetermined area may not overlap the setting plate 200 .

When the setting plate 200 vibrates, the predetermined area vibrates with a larger amplitude than the contact area of the vibration transmission body 100. The contact area of the vibration transmission body 100 refers to the area where the vibration transmission body 100 is in contact with the installation plate 200 when the vibration transmission body 100 is installed in the installation groove 211. Such an open hole 212 may be provided on the lower side of the mounting groove 211. In addition, the open hole 212 may be a long hole elongated in the front-rear direction.

In addition, the setting plate main body 210 may have a peripheral surface 212a. The perimeter surface 212a may form an open hole 212 . Such a peripheral surface 212 a may surround a side surface of the protrusion 120 when the vibration transmission body 100 is mounted on the installation plate 200 . For example, when the vibration transmitting body 100 is mounted on the setting plate 200, the peripheral surface 212a may be spaced apart from the protrusion 120 by a predetermined distance.

The guide pin unit 220 may fix at least one of the customer tray CT and the setting table 20 to the setting plate 200 . As an example, the guide pin unit 220 may have a conical shape. In addition, the guide pin unit 220 may be attached to the upper surface of the setting plate 200. Referring to FIG. Such a guide pin unit 220 may include a tray guide pin 221 and a table guide pin 222. Referring to FIG.

The tray guide pins 221 may prevent the customer tray CT mounted on the vibratory conveying body 100 from moving more than a predetermined distance in the front-rear direction and the left-right direction with respect to the setting plate 200 . Such tray guide pins 221 may be provided in plural. The table guide pin 222 can prevent the setting table 20 from moving more than a predetermined distance in the front-rear direction and the left-right direction relative to the setting plate 200. Referring to FIG. Such table guide pins 222 may be provided in plural.

The vibration motor assembly 300 may generate a vibration force for removing the off-groove phenomenon of the electronic component (D). Such a vibration motor assembly 300 may be connected to a lower end of the setting plate 200 . Such a vibration motor assembly 300 may be disposed on the lower side of the vibration transmission member 100 .

The vibration motor assembly 300 may include a motor 310 , a motor sensor 320 a motor bracket 330 and a motor support part 340 .

The motor 310 can generate vibrations. One side of such a motor 310 may be provided with an eccentric weight. Such a motor 310 can generate vibrations through the rotation of an eccentric weight. Such a motor 310 may be controlled by the controller 13. The motor sensor 320 may sense the up and down movement of the vibration transmitting body 100 . Such a motor sensor 320 may be connected to the lower surface of the setting board 200 and disposed close to the motor 310 .

The motor bracket 330 may transmit the vibration generated in the motor 310 to the vibration transmitting body 100 . Such a motor bracket 330 upper surface may be connected to the lower surface of the vibration transmitting body 100. For example, an upper portion of the motor bracket 330 may be connected to a central portion of a predetermined area of the vibration transmitting body 100. The upper portion of such a motor bracket 330 may be disposed in the open hole 212. Referring to FIG.

Such a motor bracket 330 can fixedly support the motor 310 . A lower portion of such a motor bracket 330 may be connected to a motor support portion 340. Referring to FIG. For example, the vibration generated in the motor 310 is transmitted to the motor bracket 330, and the vibration transmitted to the motor bracket 330 may be transmitted to the vibration transmitting body 100 and the motor supporting part 340. Such a motor bracket 330 may be provided on the lower side of the vibration transmitting body 100.

The motor support part 340 may transmit the vibration received from the motor bracket 330 to the setting plate 200 . The vibration transmitted to such a fixed plate 200 may be transmitted to the vibration transmitting body 100 detachably in contact with the fixed plate 200. The vibration transmitted to the vibration transmission body 100 can be transmitted to the customer tray CT mounted on the vibration transmission body 100. In other words, the vibration generated in the motor 310 can be transmitted to the motor bracket 330, the motor support part 340, the setting plate 200, the vibration transmission body 100, the customer tray CT, and the plurality of motor elements D loaded on the customer tray CT. Such a motor support part 340 may be attached to the lower surface of the setting plate 200 . For example, the motor supporting part 340 may be disposed on both sides in the width direction close to the open hole 212.

The lifting module 12 can raise or lower the vibration module 11 . Such a lifting module 12 may include a supporting part 12a, a moving part 12b, a guide rail 12c, a driving part 12d, a cable bearing 12e, and a damper 12f.

The support part 12a may support the vibration module 11 . For example, the upper surface of the support portion 12a may be connected to the lower surface on the front side of the installation plate 200, and the front surface may be connected to the moving portion 12b. The rear side of the moving part 12b may be connected to the front side of the support part 12a. For example, the moving part 12b is connected to the front side of the supporting part 12a, and moves up and down together with the supporting part 12a and the vibration module 11. The front side of such a moving part 12b may be connected to the rear side of the guide rail 12c. For example, the moving part 12b is movably connected to the rear side of the guide rail 12c, and may be configured to slidably move in the up-down direction.

The guide rail 12c can guide the sliding movement of the moving part 12b. For example, guide rail 12c may include rollers, conveyor belts, or the like. Such guide rails 12c may be extended in the vertical direction. The driving part 12d can provide a lifting driving force to the moving part 12b. Such a drive unit 12d can be controlled by the controller 13 .

The cable holder 12e (cable vayor) can be used to protect the wires (not shown) that supply power to the motor 310 and the cables (not shown) connected to the motor sensor 320 for controlling the sensors of the motor 310 . The lower portion of such a cable support 12e may have, for example, a "U" shape. Such a cable holder 12e may be provided close to the driving portion 12d.

When the descending vibration module 11 stops, the damper 12f may serve to reduce the impact applied to the vibration module 11 due to inertia. Such a damper 12f may be provided at a lower portion of the guide rail 12c.

The controller 13 can control the lifting module 12 to make the vibration module 11 rise and fall. For example, the controller 13 can control the driving part 12d to make the vibration module 11 rise or fall. In addition, when the vibration module 11 is lowered, the controller 13 can control the vibration motor assembly 300 so that the vibration motor assembly 300 generates an exciting force.

For example, when the vibration module 11 is lowered, the controller 13 can control the driving part 12d and the motor 310 so that the motor 310 is driven; Generate an exciting force. In addition, when the setting plate 200 and the setting table 20 are spaced apart, the controller 13 controls the vibration motor assembly 300 so that vibration is generated in the vibration transmission body 100 .

Such a controller 13 can be implemented by an arithmetic device including a microprocessor, and its implementation method is obvious to those skilled in the art, so further detailed description thereof will be omitted.

The front-back and left-right lengths of such an opening are smaller than the front-back and left-right lengths of the customer tray CT. The customer tray CT may be set between the lower surface of such a setting table 20 and the upper surface of the setting plate 200 . Such an installation table 20 may be installed on the upper side of the installation board 200 .

The operation and effect of the test handler 1 according to the first embodiment of the present invention will be described below.

The test handler 1 vibrates in the customer tray CT, and the electronic components D deviated from the grooves among the plurality of electronic components D loaded on the customer tray CT can be normally mounted on the customer tray CT. For example, the vibration generated in the vibration motor assembly 300 may be transmitted to the vibration transmitting body 100 and the setting plate 200. In addition, the setting board 200 may transmit the received vibration to the vibration transmitting body 100 .

The vibration transmission body 100 can transmit the vibration transmitted by the installation plate 200 and the motor bracket 330 to the customer tray CT installed on the installation surface. For example, the vibration transmitting body 100 receiving the vibration may vibrate the customer tray CT by an operation of at least a part being separated from the setting plate 200. The process of contacting the setting plate 200 after the area of the vibrating transmission body 100 that receives the vibration is separated from the setting plate 200 can be repeated.

When such a customer tray CT vibrates, the electronic components D deviated from the grooves among the plurality of electronic components D loaded on the customer tray CT can be normally mounted on the customer tray CT.

Such a vibration motor assembly 300 can generate vibration when the setting plate 200 is lowered from the state where the setting plate 200 and the setting table 20 are spaced apart. In other words, in a state where the setting plate 200 and the setting table 20 are not spaced from each other, the vibration motor assembly 300 may not be driven.

Such a test handler 1 is configured to be detachable from the setting plate 200 according to the vibration transmission body 100, which has an effect of maximizing the vibration force transmitted to the customer tray CT.

On the one hand, in addition to such features, according to the second embodiment of the present invention, the vibration transmission body 100 may further include a tray support portion 110 and a protrusion portion 120 . Next, referring to Fig. 5 and Fig. 6 again, a second embodiment of the present invention will be described. In the description of the second embodiment, differences from the above-described embodiment will be mainly explained, and the same description and reference numerals will be referred to as above-described embodiment.

The tray support part 110 may support a customer tray CT. Such a customer tray CT can be mounted on the upper surface of such a tray support. Such a tray support portion 110 can be brought into contact with the upper surface of the mounting plate 200 when the vibrating transmission body 100 is mounted in the mounting groove 211. Taking such a tray support portion 110 as an example, it may have a plate shape extending in the horizontal direction.

The protrusion part 120 may protrude downward by a predetermined thickness from the lower surface of the tray support part 110 . The thickness of such a protrusion 120 may be defined as the separation distance between the lower surface of the tray supporting part 110 and the lower surface of the protrusion. A protrusion may be provided on a lower surface of the tray support part 110 . Such protrusions 120 may be provided in the open holes 212 when the vibration transmitting body 100 is mounted in the mounting groove 211.

Referring again to FIG. 6 , the length of the protrusion 120 (eg, the length in the front-rear direction of the protrusion 120 ) may be smaller than the length of the opening hole 212 (eg, the length in the front-rear direction of the opening hole 212 ). In addition, the width of the protrusion 120 (for example, the length of the protrusion 120 in the left-right direction) is smaller than the width of the opening 212 (for example, the length of the opening 212 in the left-right direction).

For example, the circumference of the outer surface of the protrusion 120 may be smaller than the circumference of the inner circumference of the installation plate main body 210 forming the opening hole 212 . In other words, the area of the lower surface of the protrusion 120 may be smaller than the area of the virtual horizontal open surface formed by the opening hole 212 . The horizontal open surface may be defined as an area that overlaps when the open hole 212 and the virtual horizontal surface are projected relative to each other in the up-down direction. In addition, the thickness of the protrusion 120 in the up-and-down direction may be smaller than the distance between the upper and lower ends of the open hole 212. A lower surface of such a protrusion 120 may be connected to a motor bracket 330 . In addition, the protrusion part 120 may be integrally formed with the tray support part 110. Referring to FIG. However, the idea of the present invention is not limited thereto, and the protrusion part 120 is formed by the tray support part 110 and an additional part, and may be connected to the lower surface of the tray support part 110. Referring to FIG.

The operation and effect of the test handler 1 according to the second embodiment of the present invention will be described below.

When the vibration transmission body 100 vibrates, the protruding portion 120 of the test handler 1 can contact the inner peripheral surface of the setting plate main body 210 forming the opening hole 212 when it is inclined relative to the setting plate 200 . When vibration is generated in the vibration transmission body 100 by such protrusions 120, there is an effect of preventing the tray support 110 from being inclined at a predetermined angle or more with respect to the installation plate 200.

On the one hand, in addition to these features, according to the third embodiment of the present invention, the vibration transmitting body 100 may further include a spacer 130 . Hereinafter, referring to FIGS. 7 to 12 again, the third embodiment of the present invention will be described.

On the one hand, in addition to these features, according to the fourth embodiment of the present invention, the length of the spacer 130 of the vibration transmitting body 100 can be smaller than the width of the protrusion 120. Hereinafter, referring to Fig. 13 and Fig. 14 again, a third embodiment of the present invention will be described. In the description of the third embodiment, differences from the above-mentioned embodiment will be mainly explained, and the same description and reference numerals will be referred to as above-mentioned embodiment.

The length of the spacer 130 in the front-rear direction may be smaller than the width of the protrusion 120 in the left-right direction. For example, the length in the front-back direction of the spacer 130 may be less than half of the width in the left-right direction of the protrusion 120 . The width in the left-right direction of such a spacer 130 may be the same as the length in the front-rear direction.

The width of the upper end of the lower portion of such a spacer 130 may be greater than the width of the lower end of the lower portion of the spacer 130 . A lower portion of such a spacer 130 may have a shape of a curvature convex outward. In other words, the lower portion of the spacer 130 may form an arc. The lower surface of such a spacer 130 may be formed in at least one of a circle (see FIG. 13 ) and a rectangle (see FIG. 14 ), as an example.
