[0021] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1 to 5As shown, one embodiment of this utility model provides a transmission mechanism, including a mounting frame 1, a first driving member 2, a driving connector 3, and a gripper assembly 4. The first driving member 2 is mounted on the mounting frame 1, which has a receiving space 11. The two ends of the driving connector 3 along its length are a connecting end and a receiving end, respectively. The receiving end is housed in the receiving space 11, and the connecting end is connected to the gripper assembly 4, which can grip a material plate. The first driving member 2 can drive the driving connector 3 to be released from or retracted into the receiving space 11, thereby driving the gripper assembly 4 to reciprocate along a first direction to convey the material plate.

[0023] When the first driving member 2 drives the driving connector 3 to be released from the receiving space 11, the driving connector 3 drives the gripper assembly 4 away from the mounting frame 1 along the first direction. When the first driving member 2 drives the driving connector 3 to be retracted into the receiving space 11, the driving connector 3 drives the gripper assembly 4 to approach the mounting frame 1 along the first direction. The gripper assembly 4 clamps the material plate. As the driving connector 3 moves, the material plate is conveyed.

[0024] By setting up the accommodating space 11, the driving connector 3 can be retracted and extended under the drive of the first driving member 2. When the retraction and extension actions are performed, the connecting end drives the gripper assembly 4 to move and form a reciprocating motion. After the gripper assembly 4 clamps the material plate, it can drive the material plate to move, thereby realizing the conveying of the material plate. In this embodiment, the first driving member 2 can drive the gripper assembly 4 to move and convey the material plate through the driving connector 3. Fewer transmission parts are used, which can simplify the structure of the transmission mechanism and reduce production costs.

[0025] In one embodiment, the material board is a PCB board, and the first direction is defined as the horizontal direction. The transmission mechanism can realize the exchange and transportation of the material board processed on the drilling machine and the material board to be processed on the temporary storage table. When the material board to be processed on the temporary storage table is transported to the drilling machine, after the gripper assembly 4 clamps the material board, the first driving member 2 drives the driving connecting member 3 to extend from the receiving space 11, driving the gripper assembly 4 to approach the drilling machine, thereby pushing the material board into the drilling machine. When the processed material plate on the drilling machine is conveyed to the temporary storage platform, the first driving component 2 first drives the driving connector 3 to extend out of the receiving space 11. The driving connector 3 drives the gripper assembly 4 to clamp onto the first edge of the processed material plate. Then, the first driving component 2 drives the gripper assembly 4 to move a certain distance away from the drilling machine through the driving connector 3 until the first edge of the material plate overlaps the temporary storage platform. After the gripper assembly 4 releases the processed material plate, the first driving component 2 drives the gripper assembly 4 to move until the gripper assembly 4 crosses the second edge of the processed material plate opposite to the first edge. After the gripper assembly 4 clamps onto the second edge, the first driving component 2 drives the driving connector 3 into the receiving space 11 and drives the gripper assembly 4 to move, so that the gripper assembly 4 pushes the processed material plate onto the temporary storage platform, thereby completing the unloading action of the processed material plate.

[0026] It should be noted that when the PCB board bin is connected to the temporary storage platform, the transmission mechanism can also transfer the board between the temporary storage platform and the bin. When the bin is loaded onto the temporary storage platform, the conveying mechanism on the bin transports the board out, so that the board overlaps on the temporary storage platform. After the gripper assembly 4 clamps the board, under the drive of the first drive component 2, the gripper assembly 4 moves the board onto the temporary storage platform. When the temporary storage platform is feeding the board into the bin, after the gripper assembly 4 clamps the board, the first drive component 2 drives the gripper assembly 4 to move through the drive connector 3. The gripper assembly 4 pushes the board to move, so that the board enters the bin. Finally, under the action of the bin's conveying mechanism, the board is completely loaded into the bin, completing the transfer of the board.

[0027] In one embodiment, such as Figure 2 As shown, the output end of the first driving member 2 is connected between the connecting end and the receiving end. The driving connector 3 is divided into a first part 31 and a second part 32 that are connected to each other, with the output end of the first driving member 2 as the reference. The connecting end is the end of the first part 31 that is away from the second part 32, and the receiving end is located on the second part 32. It can be understood that the driving connector 3 moves under the drive of the first driving member 2, and the length of the first part 31 and the length of the second part 32 will change continuously, so that the driving connector 3 can be released from the receiving space 11 or retracted into the receiving space 11.

[0028] When the drive connector 3 is released from the receiving space 11, the length of the first part 31 gradually increases, while the length of the second part 32 gradually decreases. The length of the drive connector 3 stored in the receiving space 11 decreases. As the first part 31 lengthens, the drive connector 3 drives the gripper assembly 4 away from the mounting frame 1 along the first direction. When the drive connector 3 is retracted into the receiving space 11, the length of the first part 31 gradually decreases, while the length of the second part 32 gradually increases. The length of the drive connector 3 stored in the receiving space 11 increases. As the first part 31 shortens, the drive connector 3 drives the gripper assembly 4 closer to the mounting frame 1. Through the changes in the length of the first part 31 and the second part 32, the gripper assembly 4 reciprocates towards or away from the mounting frame 1, thereby realizing the conveying and transfer of the material plate.

[0029] In one embodiment, such as Figure 3 , Figure 4 As shown, the gripper assembly 4 includes a connecting base 41, a second driving member 42, and a gripper 43. The connecting base 41 is connected to the connecting end, and the first driving member 2 can drive the connecting base 41 to move through the driving connector 3. The second driving member 42 is mounted on the connecting base 41, and the output end of the second driving member 42 is connected to the gripper 43. The second driving member 42 can drive the gripper 43 to move along a second direction perpendicular to the first direction, so that the gripper 43 and the connecting base 41 can clamp or release the material plate.

[0030] When the material plate needs to be clamped, the first drive unit 2 moves the connecting seat 41 to the material plate, and the second drive unit 42 drives the gripper 43 to move and clamp the material plate. After the material plate is clamped, the connecting seat 41 moves back and forth under the drive of the first drive unit 2, which moves the material plate clamped by the gripper 43. After reaching the target position, the gripper 43 releases the material plate, thus realizing the conveying of the material plate.

[0031] In one embodiment, the second drive element 42 is a cylinder.

[0032] In one embodiment, such as Figure 5 As shown, the output direction of the second driving member 42 is perpendicular to the movement direction of the gripper 43. The output direction of the second driving member 42 is the first direction, and the gripper 43 moves along the second direction, which is a vertical direction perpendicular to the first direction.

[0033] The second driving member 42 drives the gripper 43 to move vertically. When the second driving member 42 drives the gripper 43 to move upward, one end of the gripper 43 can extend above the connecting seat 41, forming a gap between the gripper 43 and the upper surface of the connecting seat 41. After the material plate enters the gap, the second driving member 42 drives the gripper 43 to move downward, pressing the material plate between the gripper 43 and the upper surface of the connecting seat 41. As the connecting seat 41 moves, it moves the material plate towards the destination. After it reaches the destination, the second driving member 42 drives the gripper 43 to move upward, and the gripper 43 no longer presses the material plate, releasing it.

[0034] In one embodiment, such as Figure 4 As shown, a sensor 414 is provided on the connecting seat 41. The sensor 414 is used to detect whether the material plate has moved into the gap between the gripper 43 and the connecting seat 41. When the sensor 414 detects that the material plate is in place, the output end of the second driving member 42 extends out, driving the gripper 43 to move downward and press the material plate.

[0035] In one embodiment, such as Figure 4 , Figure 5 As shown, the gripper assembly 4 also includes an adapter plate 44 and a connecting rod 45. The adapter plate 44 is mounted on the output end of the second drive member 42, and the connecting rod 45 is rotatably connected to the connecting seat 41. One end of the connecting rod 45 is connected to the adapter plate 44, and the other end of the connecting rod 45 is connected to the gripper 43. The adapter plate 44 and the connecting rod 45 are connected by a hinge shaft 46.

[0036] The second driving component 42 drives the adapter plate 44 to move horizontally. The adapter plate 44 is connected to the connecting rod 45. The adapter plate 44 can drive the connecting rod 45 to rotate around the hinge axis 46. The end of the connecting rod 45 connected to the adapter plate 44 moves with the adapter plate 44, so that the other end of the connecting rod 45 can move up and down in the vertical direction, thereby driving the gripper 43 to move up and down.

[0037] In one embodiment, such as Figure 5 As shown, the adapter plate 44 is provided with a first groove 441, the gripper 43 is provided with a second groove 433, one end of the connecting rod 45 is rotatably connected in the first groove 441, and the other end of the connecting rod 45 is rotatably connected in the second groove 433. While the connecting rod 45 rotates around the hinge shaft 46, one end of the connecting rod 45 rotates relative to the adapter plate 44, and the other end of the connecting rod 45 rotates relative to the gripper 43.

[0038] In one embodiment, such as Figure 5As shown, the connecting rod 45 includes a first rod body 451 and a second rod body 452. The extension direction of the first rod body 451 is different from that of the second rod body 452. The first rod body 451 is connected to the adapter plate 44 and one end of the second rod body 452. The other end of the second rod body 452 is connected to the gripper 43. The hinge shaft 46 is located at the connection between the first rod body 451 and the second rod body 452.

[0039] When the second driving member 42 moves the adapter plate 44, the first rod 451 rotates around the hinge axis 46. The adapter plate 44 drives the end of the first rod 451 away from the second rod 452 to move along the first direction. Since the extension direction of the first rod 451 is different from that of the second rod 452, when the second rod 452 rotates around the hinge axis 46 under the drive of the second driving member 42, the end of the second rod 452 away from the first rod 451 moves in the vertical direction, thereby driving the gripper 43 to move in the vertical direction. In this embodiment, the output end of the second driving member 42 extends in the horizontal direction. Both the first rod 451 and the second rod 452 can rotate around the hinge axis 46, and their extension directions are different, which can change the direction of force transmission, so that the gripper 43 can move in the vertical direction under the drive of the second driving member. At the same time, it can also reduce the space occupied by the second driving member 42, the connecting rod 45, and the gripper 43 on the connecting seat 41, and reduce the overall volume of the gripper assembly.

[0040] Preferably, the angle between the first rod 451 and the second rod 452 is an acute angle.

[0041] In one embodiment, such as Figure 3 As shown, multiple grippers 43 are arranged side-by-side along the adapter plate 44. The second driving member 42 can simultaneously drive multiple grippers 43 to move. Correspondingly, the number of connecting rods 45 is the same as the number of grippers 43. The second driving member 42 drives the adapter plate 44 to move, and then each connecting rod 45 drives the corresponding gripper 43 to move up and down, so that multiple grippers 43 can simultaneously clamp or release the material plate. In this embodiment, by setting multiple grippers 43, the clamping effect on the material plate can be increased, and the stability during the material plate conveying process can be improved.

[0042] In one embodiment, such as Figure 5 As shown, the gripper 43 includes a gripper body 431 and a guide member 432. The guide member 432 connects the connecting rod 45 and the gripper body 431. The second groove 433 is provided on the guide member 432. The second driving member 42 can drive the gripper body 431 to move through the connecting rod 45 and the guide member 432, so that the gripper body 431 abuts against the material plate or leaves the material plate.

[0043] The guide member 432 extends vertically, and the output end of the second drive member 42 extends horizontally, driving the adapter plate 44 to move horizontally. Through the connecting rod 45, this movement is converted into the movement of the guide member 432 in the vertical direction, thereby realizing the vertical movement of the gripper body 431.

[0044] When the second driving member 42 moves the adapter plate 44, it can drive the guide member 432 to move up and down through the connecting rod 45, which in turn drives the gripper body 431 to move up and down. When the gripper 43 moves upward, a gap is formed between the gripper body 431 and the upper surface of the connecting seat 41. After the material plate enters the gap, the second driving member 42 drives the gripper body 431 to move downward through the connecting rod 45 and the guide member 432. The gripper body 431 abuts against the material plate, and the material plate is pressed between the gripper body 431 and the connecting seat 41. After the material plate is conveyed, the gripper 43 moves upward, and the gripper body 431 leaves the material plate, so that the gripper 43 can release the material plate.

[0045] In one embodiment, such as Figure 4 As shown, the connecting seat 41 is provided with a guide groove 411, which extends along the second direction, that is, it extends vertically. A guide member 432 is disposed in the guide groove 411. When the second driving member 42 moves the guide member 432 via the connecting rod 45, the guide member 432 can move along the guide groove 411, thereby causing the gripper body 431 to move closer to or away from the connecting seat 41, thus pressing or releasing the material plate. When the second driving member 42 moves the gripper body 431 downwards via the connecting rod 45 and the guide member 432, the gripper body 431 moves closer to the connecting seat 41, thereby pressing the material plate between the gripper body 431 and the connecting seat 41. When the gripper body 431 moves upwards, the gripper body 431 moves away from the connecting seat 41, allowing the gripper body 431 to release the material plate.

[0046] The guide groove 411 guides the movement of the guide member 432. By setting the guide groove 411, when the adapter plate 44 drives the connecting rod 45 to rotate, the guide member 432 can maintain its vertical movement without deviation, and will not affect the clamping effect of the gripper 43 on the material plate.

[0047] In one embodiment, such as Figure 4 As shown, the connecting seat 41 is provided with a connecting groove 412, which is connected to the guide groove 411. The adapter plate 44 is located below the connecting seat 41, and the connecting rod 45 is located in the connecting groove 412. One end of the connecting rod 45 can extend to the bottom of the connecting seat 41 and connect to the adapter plate 44, and the other end of the connecting rod 45 extends into the guide groove 411 and connects to the guide member 432, so that when the adapter plate 44 moves horizontally, the connecting rod 45 can drive the guide member 432 to move up and down.

[0048] In one embodiment, such as Figure 3 As shown, the connecting seat 41 is provided with a receiving groove 413, in which the gripper body 431 can be accommodated. When the gripper 43 moves downward, the guide member 432 is accommodated in the guide groove 411, and the gripper body 431 is accommodated in the receiving groove 413, so that the gripper 43 will not protrude from the upper surface of the connecting seat 41. When the gripper assembly 4 passes under the material plate, the gripper 43 will not interfere with the material plate, making it convenient to change the clamping position of the gripper assembly 4 on the material plate.

[0049] It is understandable that the shape of the receiving groove 413 is consistent with the outer contour of the gripper body 431, and the depth of the receiving groove 413 is consistent with the thickness of the gripper body 431.

[0050] In one embodiment, such as Figure 3 , Figure 4 As shown, the connecting seat 41 is provided with multiple traveling wheels 415. The traveling wheels 415 are located on the side of the connecting seat 41 away from the gripper 43. When the gripper assembly 4 moves in the temporary storage table, the traveling wheels 415 can reduce the frictional force on the gripper assembly 4. and / or; The connecting seat 41 is provided with a guide wheel 416, which is used to guide the gripper assembly 4 as it moves along the preset track. The guide wheel 416 can prevent the connecting seat 41 from getting stuck in the preset track when the drive connector 3 moves the gripper assembly 4. The preset track is set on the temporary storage platform.

[0051] In one embodiment, such as Figure 3 As shown, the connecting seat 41 is provided with a guide groove 417, which is used to guide the pins on the material plate. When the gripper assembly 4 approaches the material plate, the pins on the material plate enter the guide groove 417, which can guide the position of the material plate. At the same time, when the gripper assembly 4 passes under the material plate, it can also prevent the pins from interfering with the connecting seat 41.

[0052] In one embodiment, such as Figure 1 , Figure 2 As shown, the drive connector 3 is a chain, and the first drive component 2 includes a motor 21, a connecting shaft 22, and at least one sprocket. One end of the connecting shaft 22 is connected to the output end of the motor 21, and the connecting shaft 22 is mounted on the mounting frame 1. The sprocket and the chain mesh. The motor 21 can drive the connecting shaft 22 to rotate, and under the meshing action of the sprocket and the chain, it can drive the chain to move, so as to release the chain from the receiving space 11 or store it in the receiving space 11.

[0053] The chain is a rigid chain. The motor 21 drives the sprocket on the connecting shaft 22 to rotate. There is a virtual reference circle at the point where the tooth thickness and tooth groove width are equal. When the running trajectory of a certain link of the chain intersects the above-mentioned reference circle of the sprocket, the link begins to mesh with the sprocket. As the sprocket rotates, it causes the rigid chain to move.

[0054] The system includes multiple sprockets spaced apart along the connecting shaft 22. Multiple drive connectors 3 are also provided, with each sprocket meshing with a corresponding chain. The motor 21 and connecting shaft 22 enable the movement of multiple chains.

[0055] In one embodiment, such as Figure 1 As shown, multiple gripper assemblies 4 are provided, and the number of drive connectors 3 is twice that of drive connectors 3. The gripper assembly 4 is connected to two drive connectors 3, and the connecting seat 41 is located between the two drive connectors 3. Under the drive of the first drive member 2, the gripper assembly 4 can be balanced by force and run smoothly.

[0056] In one embodiment, such as Figure 1 As shown, the connecting shaft 22 includes multiple sub-shafts connected in sequence, and adjacent sub-shafts are connected by couplings.

[0057] On the other hand, this utility model embodiment provides a temporary storage platform, including a temporary storage platform body and the transmission mechanism described in the above embodiment. The gripper assembly 4 can clamp the material plate placed on the temporary storage platform body and send the material plate out or into the temporary storage platform body under the drive of the first driving member 2.

[0058] In another aspect, this utility model embodiment provides a PCB board conveying system, including a temporary storage platform, a workbench, and a board-matching robot as described in the above embodiment. The temporary storage platform is disposed between the board-matching robot and the workbench of the drilling machine, and a transmission mechanism is used for transferring the board between the board-matching robot and the workbench.

[0059] The board-assembly robot includes an AGV base and a material bin. The AGV base can drive the material bin to move. After the board is pulled out of the material bin, the transmission mechanism can receive the board and transfer the board to be processed to the main body of the temporary storage platform for buffering.

[0060] When the material plate to be processed on the temporary storage table is conveyed to the drilling machine, the first driving member 2 drives the driving connecting member 3 to extend from the receiving space 11, so that the gripper assembly 4 approaches the material plate. Then, the second driving member 42 drives the gripper 43 to move downward, pressing the material plate to be processed between the gripper body 431 and the connecting seat 41. After that, the first driving member 2 continues to drive the driving connecting member 3 to move, so that the gripper assembly 4 approaches the drilling machine, and the gripper assembly 4 pushes the material plate into the drilling machine.

[0061] When the processed material plate on the drilling machine's worktable is conveyed to the temporary storage platform, the first driving member 2 first drives the driving connector 3 to extend from the receiving space 11. The driving connector 3 drives the gripper assembly 4 to approach the material plate. The second driving member 42 drives the gripper 43 to move downward, and the gripper 43 clamps the first edge of the processed material plate. Then, the first driving member 2 drives the gripper assembly 4 to move a certain distance away from the drilling machine through the driving connector 3 until the first edge of the material plate overlaps the temporary storage platform. The second driving member 42 drives the gripper 43 to move upward. After releasing the processed material plate, the second driving member 42 drives the gripper 43 to move downward, so that the gripper body 431 is accommodated in the receiving groove 413. The first driving member 2 drives the gripper assembly 4 to pass under the material plate until the gripper assembly 4 crosses the second edge of the processed material plate opposite to the first edge. After the gripper 43 clamps on the second edge, the first driving member 2 drives the driving connector 3 to gradually enter the receiving space 11, driving the gripper assembly 4 to move, so that the gripper assembly 4 pushes the processed material plate onto the temporary storage table, thereby completing the unloading action of the processed material plate.

[0062] The transmission mechanism can push the processed material plates on the temporary storage table to the material box. The material plates are stored one by one in the material box. In this way, the material plates to be processed in the material box are sent out and the processed material plates are received. Then, the material box is moved to the next process by the AGV base.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
