In order that the above objects, features and advantages of the application will be readily understood, a more particular description of the application will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the application, whereby the application is not limited to the specific embodiments disclosed below.

Referring to fig. 1 and 2, fig. 1 is a perspective view of a tilting mechanism according to an embodiment of the application. Fig. 2 shows an enlarged structural view of fig. 1 at a. The present application provides a clamping assembly 10 for being mounted on a first bracket 20, wherein the clamping assembly 10 includes a first driving mechanism 11 and two swinging assemblies 12. The first driving mechanism 11 includes a servo cylinder 111, and the first driving mechanism 11 is provided on the first bracket 20. Two swing assemblies 12 are rotatably and spacedly disposed on the first bracket 20, each swing assembly 12 including a clamping lever 121 for clamping the material 30. The first driving mechanism 11 is respectively connected with the two swinging assemblies 12, and the first driving mechanism 11 is used for driving each swinging assembly 12 to swing synchronously, so that the two clamping rods 121 are close to each other to clamp the material 30 or are far away from each other to loosen the material 30.

It should be noted that, the servo cylinder 111 is a modularized product designed by integrating a servo motor and a screw, converts the rotary motion of the servo motor into linear motion, and simultaneously converts the best advantage of the servo motor, namely, precise rotational speed control, precise torque control into precise speed control, precise position control and precise thrust control, so that high-precision linear motion can be realized.

The clamping assembly 10 described above, the first driving mechanism 11 drives each swinging assembly 12 to swing synchronously, so that the two clamping rods 121 can be close to each other to clamp the material 30 or far away from each other to loosen the material 30. Since the first driving mechanism 11 in this embodiment includes the servo cylinder 111, the servo cylinder 111 acts on each swinging assembly 12 in a linear pushing manner, and after the swinging assembly 12 is pushed by the servo cylinder 111, the linear pushing action of the servo cylinder 111 can be converted into rotation. The servo electric cylinder 111 is a high-precision instrument, and can control the speed and the torque more accurately, so that the clamping degree of the two clamping rods 121 on the material 30 is flexible and controllable, the material 30 can be prevented from being too loose or too tight, the clamping force can be timely and accurately adjusted according to the property of the material 30 and/or the thickness of the material 30, and thus, the material 30 with different thickness can be stably clamped, and meanwhile, the damage to the material 30 can be prevented.

Referring to fig. 1 and 2, in some embodiments, the cross-sectional profile of the clamping rod 121 along the length direction thereof includes, but is not limited to, regular shapes such as circles, ellipses, polygons, and other irregular shapes, and is specifically flexibly adjusted and set according to practical requirements, and the clamping rod is not limited herein, as long as the clamping of the material 30 can be achieved by tightly pressing against the side surface of the material 30 without puncturing and damaging the material 30.

Referring to fig. 1 and 2, in one embodiment, the clamping rod 121 includes a frame and an elastic material disposed on the frame, and the elastic material is used to abut against the material 30. Specifically, the elastic material may be a sleeve body sleeved on the framework, or may be an elastomer attached to the outer wall of the framework, for example, and the like, and specifically may be flexibly adjusted and set according to actual needs, which is not limited herein. The skeleton is used as a structural support, so that the overall structural rigidity of the clamping rod 121 is high enough to realize stable clamping of the material 30, and damage to the material 30 can be reduced when the elastic material is contacted with the material 30.

Referring to fig. 1 and 2, in one embodiment, the swing assembly 12 further includes a rotation shaft 122 rotatably connected to the first bracket 20, and a first swing arm 123 and a transmission unit 124 respectively connected to the rotation shaft 122. The first swing arm 123 is also connected to the clamping lever 121, and the first driving mechanism 11 is connected to the transmission unit 124. Thus, when the first driving mechanism 11 works, the driving transmission unit 124 is driven to act, the transmission unit 124 can correspondingly drive the rotating shaft 122 to rotate, the rotating shaft 122 drives the first swinging arm 123 to swing, and the first swinging arm 123 drives the clamping rod 121 to clamp or unclamp the material 30 when swinging.

Referring to fig. 1 and 2, in some embodiments, the swing assembly 12 further includes a bearing 125 disposed on the first bracket 20. The rotation shaft 122 is rotatably inserted into the bearing 125. In this way, the rotation shaft 122 can be stably rotated by the supporting action of the bearing 125.

Referring to fig. 1 and 2, in one embodiment, the first driving mechanism 11 further includes a first pushing arm 112 connected to the servo cylinder 111. The transmission unit 124 includes a transmission shaft 1241 and a mounting seat 1242 fixedly connected to the rotation shaft 122. The mounting seat 1242 is provided with a shaft hole. The transmission shaft 1241 is movably disposed in the shaft hole along the axial direction, and the transmission shaft 1241 is rotatably connected with the first pushing arm 112. Thus, when the first driving mechanism 11 drives the first pushing arm 112 to move back and forth, the first pushing arm 112 can synchronously drive the transmission shaft 1241 to rotate, and when the transmission shaft 1241 rotates, the mounting seat 1242 can be driven to rotate and adaptively move along the shaft hole, and the mounting seat 1242 correspondingly drives the rotation shaft 122 to rotate, so that the linear motion of the first driving mechanism 11 can be converted into the rotation motion of the rotation shaft 122.

Referring to fig. 1 and 2, in one embodiment, the transmission unit 124 further includes a wear sleeve 1243 disposed in the shaft hole. The transmission shaft 1241 is inserted into the wear sleeve 1243. Therefore, the wear-resistant sleeve 1243 has small wear, can prolong the service life, reduce noise caused in the movement process, improve the movement precision and realize stable clamping of film materials with different thicknesses.

In some embodiments, the wear sleeve 1243 includes, but is not limited to, a metal sleeve such as a copper sleeve, an aluminum sleeve, a stainless steel sleeve, or a non-metal sleeve such as a rubber sleeve, and may be specifically selected according to practical requirements.

Referring to fig. 1 and 2, in one embodiment, there are at least two first driving mechanisms 11, at least two transmission units 124 of each swing assembly 12, each first driving mechanism 11 is correspondingly connected to each transmission unit 124 of one swing assembly 12, and each first driving mechanism 11 is correspondingly connected to each transmission unit 124 of the other swing assembly 12. In this way, when the clamping assembly 10 is operated, the first driving mechanisms 11 are synchronously operated, so that each swinging assembly 12 is driven to move by at least two transmission units 124, and stable clamping of the material 30 can be realized.

Alternatively, the number of first drive mechanisms 11 includes, but is not limited to, two, three, four, or more. In this embodiment, the number of the first driving mechanisms 11 is two, for example, and the two first driving mechanisms 11 are respectively located at two opposite sides of the first bracket 20. The transmission units 124 of each swing assembly 12 are respectively two, and are respectively positioned at two opposite ends of the rotating shaft 122. In this way, when the two first driving mechanisms 11 move synchronously and respectively drive the two transmission units 124 of each swinging assembly 12 to act, the two transmission units 124 of each swinging assembly 12 respectively act on the opposite ends of each rotating shaft 122, so that the rotating shafts 122 stably rotate, and the clamping rods 121 can stably clamp the material 30. In addition, as the two first driving mechanisms 11 and the two swinging assemblies 12 are positioned at the two opposite ends of the rotating shaft 122, the arrangement is reasonable, and interference with the material 30 can be avoided.

Of course, in some embodiments, the first driving mechanism 11 may be provided as one.

Referring to fig. 1 and 2, in some embodiments, the length of the clamping rod 121 is greater than or equal to 60% of the width of the material 30, specifically, for example, 60%, 70%, 80%, 90%, 100%, 110% of the width of the material 30, so that the clamping rod 121 can compress the material 30 more along the width direction W of the material 30, and further stable clamping of the material 30 can be achieved.

Referring to fig. 1 and 2, in some embodiments, the rotation shaft 122 and the clamping rod 121 are separately provided, and may be provided as a whole, and for example, may extend from one side of the first bracket 20 to the other side of the first bracket 20, or may be provided as a plurality of segments, and the first swing arms 123 are correspondingly provided as a plurality and are connected in series to form a whole, or may take other structural forms.

Referring to fig. 1 and 2, in one embodiment, the clamping rod 121 includes a plurality of clamping segments 1211 sequentially spaced apart along the extension thereof. Each of the clamping segments 1211 is fixedly connected to the rotary shaft 122 by at least one first swing arm 123. In this way, the clamping rod 121 achieves clamping of the material 30 in such a way that each clamping segment 1211 is synchronously abutted against the material 30. Further, since the clamping lever 121 is provided as the plurality of clamping sections 1211 sequentially arranged at intervals along the extending direction thereof, any adjacent two of the clamping sections 1211 are provided with the interval space, which can be avoided with the first bracket 20, preventing interference from occurring.

Specifically, the rotation shaft 122 includes a plurality of shaft segments 1221 that are sequentially spaced apart in the axial direction thereof. Each shaft segment 1221 is rotatably disposed on the first bracket 20. Opposite ends of each of the clamping sections 1211 are connected to the adjacent two shaft sections 1221 by the first swing arms 123, respectively, so that the shaft sections 1221 can be connected in series to form a single body.

Referring to fig. 1-4, fig. 3 shows a top view of the block diagram of fig. 1. Fig. 4 shows a front view of fig. 1. In one embodiment, a tilting mechanism includes at least one of the clamping assemblies 10 of any of the embodiments, and further includes a first bracket 20, a second drive mechanism 40, and a second bracket 50. The clamping assembly 10 is installed on the first bracket 20, the second driving mechanism 40 is installed on the second bracket 50, the second driving mechanism 40 is connected with the first bracket 20, and the second driving mechanism 40 is used for driving the first bracket 20 to rotate.

According to the turnover mechanism, due to the fact that the clamping assembly 10 is arranged, before the material 30 is turned over, the material 30 is clamped through the clamping assembly 10, then the second driving mechanism 40 is operated, the second driving mechanism 40 drives the first support 20 to rotate, and therefore the material 30 can be turned over to a preset angle. In this embodiment, since the first driving mechanism 11 includes the servo cylinder 111, the servo cylinder 111 acts on each swinging component 12 in a linear pushing manner, and after the swinging component 12 is pushed by the servo cylinder 111, the linear pushing action of the servo cylinder 111 can be converted into rotation. The servo electric cylinder 111 is a high-precision instrument, and can control the speed and the torque more accurately, so that the clamping degree of the two clamping rods 121 on the material 30 is flexible and controllable, the material 30 can be prevented from being too loose or too tight, the clamping force can be timely and accurately adjusted according to the property of the material 30 and/or the thickness of the material 30, and thus, the material 30 with different thickness can be stably clamped, and meanwhile, the damage to the material 30 can be prevented.

Referring to fig. 1 to 4, in one embodiment, the clamping assembly 10 is provided in at least two and sequentially spaced apart on the first bracket 20. Specifically, the respective clamping assemblies 10 are sequentially arranged on the first carriage 20 at intervals along the length direction L of the material 30. In this embodiment, there are two clamping assemblies 10, and the two clamping assemblies 10 are located at the front and rear of the first bracket 20, respectively, for example. Therefore, the material 30 can be clamped at different positions along the length direction L of the material 30, so that the material 30 can be stably clamped, and loosening of the material 30 in the overturning process can be avoided.

Referring to fig. 1 to 4, in one embodiment, the turnover mechanism further includes two conveying assemblies 60 disposed on the first support 20 at intervals. The conveyor assembly 60 can drive the material 30 onto the first support 20 or drive the material 30 off the first support 20. Therefore, the material 30 can be automatically fed onto the first bracket 20, and the material 30 can be automatically fed, so that the working efficiency is high. Specifically, before the overturning mechanism overturns the material 30, the two conveying assemblies 60 synchronously feed, so that the material 30 can be conveyed to the first bracket 20, then the material 30 is clamped by the clamping assembly 10, then the overturning mechanism finishes the overturning of the material 30, then the clamping assembly 10 loosens the material 30, and the two conveying assemblies 60 synchronously feed, so that the material 30 leaves the first bracket 20.

Referring to fig. 2, in some embodiments, the conveying assembly 60 includes a third driving mechanism 61 disposed on the first support 20, a driving wheel 62 and a driven wheel 63 rotatably disposed on the first support 20, and a transmission element 64 connecting the driving wheel 62 and the driven wheel 63. The third driving mechanism 61 is connected to the driving wheel 62, and is used for driving the driving wheel 62 to rotate. The drive element 64 includes, but is not limited to, a conveyor belt. Thus, when the third driving mechanism 61 works, the driving wheel 62 and the driven wheel 63 are driven to rotate, so that the transmission element 64 is driven to move, and further the feeding or discharging action of the material 30 can be driven.

Referring to fig. 1, 3 and 4, in one embodiment, the tilting mechanism further includes a lifting mechanism 70. The lifting mechanism 70 is used for driving the second bracket 50 to lift. In this way, before the step of feeding or discharging the material 30, the lifting mechanism 70 can drive the second bracket 50 to lift, so as to drive the first bracket 20 to adjust the height position up and down, so as to compensate the height difference caused by the overturning action of the first bracket 20, so that the height of the input part on the first bracket 20 is consistent with the height of the output end of the feeding mechanism 93, and the feeding mechanism 93 can smoothly and rapidly output the material 30 to the first bracket 20, and the height of the output part on the first bracket 20 is consistent with the height of the input end of the discharging mechanism, so that the material 30 can be smoothly and rapidly output to the discharging mechanism.

Referring to fig. 1, 3 and 4, specifically, the tilting mechanism further includes a third bracket 80. The lifting mechanism 70 is mounted on the third bracket 80. The second bracket 50 is slidably disposed on the third bracket 80 up and down. In this way, when the lifting mechanism 70 drives the second bracket 50 to lift and lower the adjusting position, the second bracket 50 can slide up and down along the third bracket 80, so that the second bracket 50 can operate stably and reliably.

In some embodiments, the lifting mechanism 70 includes, but is not limited to, a screw, an air cylinder, a hydraulic cylinder, a cam mechanism, a motor driving wheel mechanism, a gear driving mechanism, etc., and can be flexibly adjusted and set according to actual requirements, which is not limited herein.

In one embodiment, the flipping mechanism further comprises a position sensor and a controller. The position sensor is disposed on the second bracket 50 and is used for sensing a rotation position of the first bracket 20, and the controller is electrically connected to the position sensor and the second driving mechanism 40, respectively. So, the position sensor sets up on the second support 50 and can sense the rotation position of first support 20 to send the rotation position of first support 20 to the controller, thereby play the effect of calibration position, under the control of controller, can realize the flip angle of accurate control first support 20, thereby can avoid taking place to overturn too much or too little condition, lead to unable and go up unloading mechanism and dock.

In one embodiment, the position sensors include, but are not limited to, two, for example, two position sensors corresponding to the loading position and the unloading position, respectively. Therefore, when the first support 20 rotates to the feeding position or the discharging position, the first support 20 can be correspondingly sensed by the corresponding position sensor, the position sensor senses sensing signals to the controller, and under the control of the controller, the first support 20 can be positioned in time after being turned in place, so that the situation that excessive or insufficient turnover occurs and the first support cannot be in butt joint with the feeding and discharging mechanism is avoided.

The controller includes, but is not limited to, a PLC control device, and is capable of correspondingly controlling the second driving mechanism 40 to act, correspondingly setting different control parameters according to materials 30 with different thickness and different material types, and implementing monitoring work data in a docking manner with the MES system.

In some embodiments, the second drive mechanism 40 comprises a servo motor. The servo motor can precisely control the rotational speed and angle of the first bracket 20. The second driving mechanism 40 includes an encoder, which can acquire rotation angle information and transmit the rotation angle information to the controller, and works under the control of the controller, so that the turnover angle position of the first bracket 20 can be precisely controlled.

Please refer to fig. 1 and fig. 2. In one embodiment, a solar cell production line includes the turnover mechanism of any of the embodiments described above.

In the solar cell production line, due to the arrangement of the clamping assembly 10, before the overturning action of the material 30, the material 30 is clamped by the clamping assembly 10, and then the second driving mechanism 40 acts, and the second driving mechanism 40 drives the first bracket 20 to rotate, so that the overturning of the material 30 to a preset angle can be realized. In this embodiment, since the first driving mechanism 11 includes the servo cylinder 111, the servo cylinder 111 acts on each swinging component 12 in a linear pushing manner, and after the swinging component 12 is pushed by the servo cylinder 111, the linear pushing action of the servo cylinder 111 can be converted into rotation. The servo electric cylinder 111 is a high-precision instrument, and can control the speed and the torque more accurately, so that the clamping degree of the two clamping rods 121 on the material 30 is flexible and controllable, the material 30 can be prevented from being too loose or too tight, the clamping force can be timely and accurately adjusted according to the property of the material 30 and/or the thickness of the material 30, and thus, the material 30 with different thickness can be stably clamped, and meanwhile, the damage to the material 30 can be prevented.

Referring to fig. 1 to 5, fig. 5 is a partial block diagram of a solar cell production line according to an embodiment of the application. The solar cell production line further comprises a paper taking gripper 91, a feeding gripper 92 and a feeding mechanism 93 which are positioned at the upstream of the turnover mechanism, and a discharging mechanism which is positioned at the downstream of the turnover mechanism. The material 30 is, for example, photovoltaic glass, and the paper taking gripper 91 can, for example, take kraft paper from the material 30, so that manual operation is not needed, and the automation degree is improved. The material 30 is then grasped by the loading gripper 92 and fed into the loading mechanism 93. The feeding mechanism 93 is specifically provided with a righting component, for example, and the righting component can righting the material 30, so that the material 30 is located in the middle position of the conveying line, and after the material 30 is righted, the material 30 is conveyed into the first bracket 20 through the feeding mechanism 93.

In one embodiment, the workflow of the solar cell production line comprises the steps of:

Placing the material 30 stacked by one supporting layer at a feeding grip 92, taking kraft paper on the material 30 by a paper taking grip 91, and then gripping the material 30 into a feeding mechanism 93 by the feeding grip 92;

The material 30 is subjected to the righting treatment by the righting component of the feeding mechanism 93, so that the material 30 is centered left and right and is placed in order, and can enter the first bracket 20 in the middle;

after the material 30 enters the preset position of the first bracket 20 under the driving of the conveying assembly 60, the material 30 is clamped by the clamping assembly 10, specifically, before the step of conveying the material 30 to the first bracket 20, the height position of the second bracket 50 can be adjusted by lifting the lifting mechanism 70, so that the input part of the first bracket 20 is aligned with the output part of the feeding mechanism 93, and the feeding action is facilitated.

The second driving mechanism 40 drives the first bracket 20 to turn over, for example, 180 degrees, so that the material 30 is turned over, and the first bracket 20 drives the material 30 to turn over, and then the material enters a blanking step;

The conveyor assembly 60 moves the material 30 such that the material 30 enters the blanking mechanism. Specifically, before the step of outputting the material 30 from the first support 20, the lifting mechanism 70 may be further used to lift and adjust the height position of the second support 50, so that the output portion of the first support 20 is aligned with the input portion of the blanking mechanism, so as to facilitate the blanking action.
