Description

Technical Field

[0001] This utility model relates to the field of PCB processing technology, and in particular to an automatic PCB board insertion machine. Background Technology

[0002] In the manufacturing process of PCBs (Printed Circuit Boards), the surface condition of the finished PCBs after the tray baking process is crucial to the final product quality. Because the surface of the baked PCBs is relatively fragile, contact or friction during subsequent transfer to the next process can easily cause scratches, affecting the product's appearance and electrical performance. Currently, the industry commonly uses manual insertion for this step, where workers manually insert each PCB into a dedicated rack. However, this manual operation mode has significant limitations: firstly, manual insertion consumes a large amount of manpower and is inefficient, especially in large-scale production scenarios, making it difficult to meet the demands of high-efficiency, batch production and hindering the overall production line's capacity improvement; secondly, during manual handling, workers' hands inevitably come into contact with the PCB surface, and sweat, grease, dust, and other impurities from their hands can easily transfer to the board, causing contamination. This contamination can not only affect the normal operation of subsequent processes but also lead to reduced insulation performance, signal transmission interference, and other quality problems, in severe cases even resulting in product scrap. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automatic PCB board insertion machine that can replace manual labor in the board insertion process, significantly improving insertion efficiency and reducing labor costs. It also avoids board surface contamination caused by manual handling, thereby helping to ensure the quality of the finished PCB boards.

[0004] An automatic PCB insertion machine according to an embodiment of the present invention includes a frame with a board picking station and a board pushing station. A first receiving cavity and a second receiving cavity are formed on the frame. Both the first and second receiving cavities are used to accommodate multiple stacked pallets. The board picking station is located at the upper end of the first receiving cavity. A first lifting support device is disposed on the frame and located within the first receiving cavity. The output end of the first lifting support device is used to support the multiple stacked pallets within the first receiving cavity. The first lifting support device can drive the multiple stacked pallets to rise, so that the multiple pallets move sequentially to the board picking station. A board picking device is disposed on the frame and is used to sequentially transport the PCBs on the pallets at the board picking station to the pusher. A third lifting support device is located on the frame at the workstation. The output end of the third lifting support device is used to support the frame body. The third lifting support device can drive the frame body to descend so that multiple slots on the frame body are sequentially aligned with the push plate workstation. A push plate device is located on the frame and is used to push the PCB at the push plate workstation sequentially into the slots on the frame body. A second lifting support device is located on the frame and within the second receiving cavity. The output end of the second lifting support device is used to support multiple stacked pallets. The second lifting support device can drive the multiple stacked pallets to descend. A pallet retrieval device is located on the frame and is used to transport the empty pallet at the retrieval workstation to the output end of the second lifting support device.

[0005] It has at least the following beneficial effects: In operation, the automatic PCB insertion machine initially contains multiple trays of PCBs stacked in the first receiving cavity. The output of the first lifting support device supports these stacked trays. The output of the second lifting support device in the second receiving cavity is empty, and the frame rests on the output of the third lifting support device. After startup, the first lifting support device rises, moving the topmost tray to the board-retrieving station. The board-retrieving device then moves the PCBs from the trays at the board-retrieving station to the board-pushing station. Simultaneously, the third lifting support device lowers the frame based on the PCB placement at the board-pushing station, aligning the slots on the frame with the board-pushing station. When a PCB is at the board-pushing station, the board-pushing device pushes it into the corresponding slot on the frame. Once all PCBs on the trays at the board-retrieving station have been removed, the board-retrieving device moves the empty trays from the board-retrieving station to the output of the second lifting support device. Next, the second lifting support device lowers the stacked empty pallets on the output end, making room for subsequent empty pallets. Then, the first lifting support device continues to raise the remaining stacked pallets in the first receiving cavity, moving the next pallet containing a PCB to the board picking station. This process of picking, pushing, and picking empty pallets is repeated until all PCB finished boards on all pallets in the first receiving cavity have been inserted. This automatic PCB board insertion machine, through its automated board picking, pushing, insertion, and empty pallet picking process, eliminates the need for manual operation. This significantly reduces labor costs, improves operational efficiency, meets the high-efficiency and batch production needs of large-scale production scenarios, and increases production line capacity. Furthermore, it avoids contact between hands and the surface of the PCB finished board during manual handling, preventing contamination from sweat, grease, dust, and other impurities, thus ensuring the quality of the finished PCB.

The first cylinder can push the PCB on the positioning mechanism from back to front so that the PCB is inserted into the slot on the frame.

[0007] According to an embodiment of the present invention, an automatic PCB insertion machine for finished boards includes a positioning mechanism comprising a first positioning block, a second positioning block, and a second cylinder.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] refer to Figure 1 , Figure 4 , Figure 6 and Figure 8 This utility model discloses an automatic PCB board insertion machine 30, including a frame 100, a first lifting support device 200, a second lifting support device 300, a third lifting support device 400, a board picking device 500, a board pushing device 730 700 and a pallet picking device 600.

[0021] The frame 100 is provided with a board picking station and a board pushing station 730. A first receiving cavity 110 and a second receiving cavity 120 are formed on the frame 100. Both the first receiving cavity 110 and the second receiving cavity 120 are used to accommodate multiple stacked pallets 20. The board picking station is located at the upper end of the first receiving cavity 110. A first lifting support device 200 is provided on the frame 100 and located within the first receiving cavity 110. The output end of the first lifting support device 200 is used to support the multiple stacked pallets 20 within the first receiving cavity 110. The first lifting support device 200 can drive the multiple stacked pallets 20 to rise, so that the multiple pallets 20 move sequentially to the board picking station. A board picking device 500 is provided on the frame 100. The board picking device 500 is used to sequentially transport the PCBs on the pallets 20 at the board picking station to the board pushing station 730. A third lifting support device 400 is provided on the frame 100. On frame 100, the output end of the third lifting support device 400 is used to support the frame 10. The third lifting support device 400 can drive the frame 10 to descend so that the multiple slots 11 on the frame 10 are aligned with the push plate 730 station in sequence. The push plate 730 device 700 is set on the frame 100 and is used to push the PCB at the push plate 730 station into the slots 11 on the frame 10 in sequence. The second lifting support device 300 is set on the frame 100 and located in the second receiving cavity 120. The output end of the second lifting support device 300 is used to support the multiple stacked pallets 20. The second lifting support device 300 can drive the multiple stacked pallets 20 to descend. The pallet 20 picking device 600 is set on the frame 100 and is used to transport the empty pallet 20 at the picking station to the output end of the second lifting support device 300.

[0022] It should be explained that, in this embodiment of the invention, the frame 10 is provided with a plurality of slots 11 evenly distributed in the vertical direction. The slots 11 are used for inserting PCBs to store them. In this embodiment of the invention, PCB refers to the finished PCB board 30.

[0023] Understandably, during the operation of the automatic PCB insertion machine 30, in the initial state, multiple trays 20 containing PCBs are stacked in the first receiving cavity 110. The output end of the first lifting support device 200 supports these stacked trays 20. No trays 20 are placed on the output end of the second lifting support device 300 in the second receiving cavity 120, and the frame 10 is placed on the output end of the third lifting support device 400. After the equipment starts, the first lifting support device 200 begins operation, driving the multiple stacked trays 20 in the first receiving cavity 110 to rise, moving the topmost tray 20 to the board picking station. Subsequently, the board picking device 500 starts, transporting the PCBs on the trays 20 at the board picking station one by one to the pusher 730 station. During this process, the third lifting support device 400 operates synchronously, driving the frame 10 to descend according to the pushing status of the PCBs at the pusher 730 station, so that the multiple slots 11 on the frame 10 are sequentially aligned with the pusher 730 station. When there is a PCB at the pusher station 730, the pusher device 700 activates, pushing the PCB into the corresponding slot 11 on the frame 10. After all the PCBs on the trays 20 at the board removal station have been removed, the board removal device 600 starts working, moving the empty trays 20 at the board removal station from the board removal station to the output end of the second lifting support device 300. Then, the second lifting support device 300 drives the multiple empty trays 20 stacked on the output end to descend, making room for the subsequent empty trays 20. Afterwards, the first lifting support device 200 continues to drive the remaining stacked trays 20 in the first receiving cavity 110 to rise, so that the next tray 20 containing a PCB moves to the board removal station, repeating the above board removal, pusher 730, and empty tray removal process until all the finished PCB boards 30 on all the trays 20 in the first receiving cavity 110 have completed the board insertion operation. This automatic PCB board insertion machine 30 automatically handles the board picking, pushing, insertion, and empty tray picking processes without manual operation. This significantly reduces labor costs, improves operational efficiency, meets the high-efficiency and batch production needs of large-scale production scenarios, and increases production line capacity. It also avoids contact between hands and the surface of the PCB board 30 when handling boards manually, preventing contamination of the board surface caused by sweat, grease, dust, and other impurities from hands, thus helping to ensure the quality of the PCB board.

[0024] In this embodiment of the invention, the worker first places the empty frame 10 on the output end of the third lifting support device 400. After the frame 10 on the output end of the third lifting support device 400 is filled with PCBs, the worker can remove the frame 10. Then the output end of the third lifting support device 400 rises and resets, and the worker places the next frame 10 to be controlled on the output end of the third lifting support device 400.

[0025] refer to Figure 1 and Figure 3 The pusher plate 730 device 700 includes a first cylinder 710, a pusher plate 730, and a positioning mechanism. The cylinder body of the first cylinder 710 is mounted on the frame 100, and the piston rod of the first cylinder 710 is connected to the pusher plate 730. The positioning mechanism is mounted on the frame 100 and located at the pusher plate 730 station. The board picking device 500 can transport the PCB to the positioning mechanism so that the positioning mechanism can position the PCB at the pusher plate 730 station and align the PCB on the positioning mechanism with the slot 11 on the frame 10. The first cylinder 710 can push the PCB on the positioning mechanism from back to front so that the PCB is inserted into the slot 11 on the frame 10. It can be understood that when the board picking device 500 transports the PCB on the tray 20 at the board picking station to the positioning mechanism at the pusher plate 730 station, the positioning mechanism immediately positions the PCB to ensure that the PCB position at the pusher plate 730 station is accurate and that the PCB on the positioning mechanism is accurately aligned with the slot 11 on the frame 10 to be inserted. After positioning is completed, the first cylinder 710 in the pusher plate 730 device 700 is activated, its piston rod extends, driving the pusher plate 730 connected to it to move from back to front. During the movement, the pusher plate 730 contacts the PCB on the positioning mechanism and continuously applies a pushing force, smoothly pushing the PCB forward along the path defined by the positioning mechanism. Under the pushing action of the first cylinder 710, the PCB gradually detaches from the positioning mechanism and is accurately inserted into the corresponding slot 11 on the frame 10. When the PCB is fully inserted into the slot 11, the piston rod of the first cylinder 710 retracts, driving the pusher plate 730 to reset, preparing for the next pusher plate 730 operation, waiting for the board picking device 500 to transport the next PCB to the positioning mechanism, repeating the above pusher plate 730 process.

[0026] refer to Figure 3 The positioning mechanism includes a first positioning block 740, a second positioning block 750, and a second cylinder 720. The first positioning block 740 and the second positioning block 750 are respectively provided with a first positioning groove 741 and a second positioning groove 751. The first positioning block 740 is mounted on the frame 100, and the cylinder body of the second cylinder 720 is mounted on the frame 100. The piston rod of the second cylinder 720 is connected to the second positioning block 750. The second positioning block 750 is located to the right of the first positioning block 740. The first positioning groove 741 and the second positioning groove 751 can accommodate the PCB. The second cylinder 720 can drive the second positioning block 750 to move to the left so that the inner sidewalls of the first positioning groove 741 and the second positioning groove 751 can abut against the PCB.

[0027] Understandably, when the board picking device 500 moves the PCB from the tray 20 at the board picking station to the pusher station 730, it places the PCB in the first positioning groove 741 and the second positioning groove 751 on the first positioning block 740 and the second positioning block 750. At this time, the second cylinder 720 is activated, and its piston rod drives the second positioning block 750 to move to the left. Since the second positioning block 750 is located to the right of the first positioning block 740, as the second positioning block 750 moves to the left, the inner sidewalls of the first positioning groove 741 and the second positioning groove 751 gradually approach and abut against the PCB, thereby completing the positioning of the PCB and ensuring that the PCB is accurately positioned at the pusher station 730 and can be accurately aligned with the slot 11 to be inserted on the frame 10. After positioning is completed, the first cylinder 710 in the pusher plate 730 device 700 is activated, the piston rod extends, and the pusher plate 730 moves from back to front. The pusher plate 730 contacts the PCB on the positioning mechanism and applies a pushing force, smoothly pushing the PCB forward along the path defined by the first positioning groove 741 and the second positioning groove 751, so that it gradually separates from the positioning mechanism and is accurately inserted into the corresponding slot 11 on the frame 10. When the PCB is fully inserted into the slot 11, the piston rod of the first cylinder 710 retracts, driving the pusher plate 730 to reset; at the same time, the piston rod of the second cylinder 720 drives the second positioning block 750 to move to the right and reset, preparing for the positioning of the next PCB, waiting for the board picking device 500 to transport the next PCB into the first positioning groove 741 and the second positioning groove 751, and repeating the above pusher plate 730 process. The second positioning block 750 is moved to the left by the second cylinder 720, so that the inner sidewalls of the first positioning groove 741 and the second positioning groove 751 abut against the PCB to achieve positioning. This method can adapt to PCBs of different sizes, and the positioning is more flexible and accurate. It effectively ensures the alignment between the PCB and the slot 11 on the frame 10, avoids problems such as offset and jamming when inserting the board due to inaccurate positioning, and improves the success rate of board insertion.

[0028] refer to Figures 4 to 6The automatic PCB insertion machine 30 also includes a temporary storage plate 130 and a shifting device 800. Both the temporary storage plate 130 and the shifting device 800 are mounted on the frame 100. The shifting device 800 is used to shift the PCB-filled frame 10 from the output end of the third lifting support device 400 onto the temporary storage plate 130. The temporary storage plate 130 supports multiple frames 10. Initially, workers manually place empty frames 10 onto the output end of the third lifting support device 400. As the equipment operates, the pusher 730 device 700 continuously pushes PCBs into the slots 11 of the frames 10. When all slots 11 on the frames 10 are filled with PCBs, the third lifting support device 400 stops descending. At this time, the PCB-filled rack 10 on the output end of the third lifting support device 400 is activated, removing it from the output end and pushing it onto the temporary storage plate 130. The temporary storage plate 130 supports the PCB-filled rack 10, ensuring its stable placement. Afterwards, workers can remove all the PCB-filled racks 10 accumulated on the temporary storage plate 130, leaving the output end of the third lifting support device 400 empty. Workers can then place new empty racks 10 on the output end of the third lifting support device 400, and the equipment continues the PCB insertion operation, repeating this cycle. The temporary storage plate 130 allows for the temporary storage of multiple PCB-filled racks 10, avoiding equipment downtime caused by the need for immediate manual removal of racks once full. This ensures continuous PCB insertion operations, improving production continuity and efficiency. Secondly, the rack device 800 automatically transfers the rack 10 filled with PCBs to the temporary storage board 130, reducing the frequency of manual intervention and lowering the risk of manual contact or collision with the PCB during the process of removing the rack 10, thus further ensuring the quality of the PCB.

[0029] refer to Figure 6 and Figure 7The lever device 800 includes a fourth linear drive mechanism 810, a fourth rotary drive member 820, and a lever 830. The fourth linear drive mechanism 810 is mounted on the frame 100. The output end of the fourth linear drive mechanism 810 is connected to the fourth rotary drive member 820, and the output end of the fourth rotary drive member 820 is connected to the lever 830. The fourth linear drive mechanism 810 can drive the fourth rotary drive member 820 and the lever 830 to move to the left and closer to the third lifting support device 400. The fourth rotary drive member 820 can drive the lever 830 to rotate, so that the lever 830 moves the frame 10 on the third lifting support device 400 onto the temporary storage plate 130. It can be understood that the lever device 800 starts working when the frame 10 on the third lifting support device 400 is full of PCBs. The fourth linear drive mechanism 810 is activated, and its output end drives the connected fourth rotary drive component 820 and lever 830 to move to the left, causing the lever 830 to gradually approach the frame 10 on the third lifting support device 400 until the lever 830 moves to a suitable operating position, able to contact the frame 10 and apply force. Then, the fourth rotary drive component 820 is activated, and its output end drives the lever 830 to rotate. During the rotation of the lever 830, the lever 830 contacts the frame 10 and applies force, using the thrust generated by the rotation to pull the frame 10 away from the output end of the third lifting support device 400. As the lever 830 continues to rotate, the frame 10 is smoothly pushed onto the temporary storage plate 130, completing the transfer of the frame 10 from the third lifting support device 400 to the temporary storage plate 130. Once the frame 10 has been successfully moved to the temporary storage plate 130, the fourth rotary drive component 820 drives the lever 830 to rotate in the opposite direction, resetting it to its initial position. At the same time, the output end of the fourth linear drive mechanism 810 drives the fourth rotary drive component 820 and the lever 830 to move to the right, returning to the initial waiting position, and preparing for the next lever operation.

[0030] refer to Figure 4 and Figure 5The third lifting support device 400 includes a third linear drive mechanism 410 and a third platform 420. The third linear drive mechanism 410 is mounted on the frame 100, and its output end is connected to the third platform 420. The third platform 420 supports the frame 10, and the third linear drive mechanism 410 can drive the third platform 420 to rise and fall. The third platform 420 is provided with a first guide groove 421 for placing the frame 10. The opening of the first guide groove 421 faces the temporary storage plate 130. Understandably, in the initial state, when a worker places an empty frame 10 into the first guide groove 421 of the third platform 420, the frame 10 is stably placed on the third platform 420 under the constraint of the first guide groove 421, since the opening of the first guide groove 421 faces the temporary storage plate 130. When the equipment starts operating and the pusher 730 device 700 prepares to push the PCB into the slot 11 of the frame 10, the third linear drive mechanism 410 is activated, and its output drives the third platform 420 to descend. Based on the PCB pushing progress at the pusher 730 station, the third linear drive mechanism 410 precisely controls the descent of the third platform 420, ensuring that the multiple slots 11 on the frame 10 are sequentially aligned with the pusher 730 station, guaranteeing that the pusher 730 device 700 can accurately push the PCB into the corresponding slot 11. Once all slots 11 on the frame 10 are filled with PCBs, the third linear drive mechanism 410 stops driving, and the third platform 420 remains in its current position. At this time, the lever device 800 starts working. After the fourth linear drive mechanism 810 drives the lever 830 close to the frame 10, the fourth rotary drive component 820 drives the lever 830 to rotate. The lever 830 acts on the frame 10. Since the frame 10 is located in the first guide groove 421 and the opening of the first guide groove 421 faces the temporary storage plate 130, the frame 10 is smoothly moved from the third platform 420 to the temporary storage plate 130 along the extension direction of the first guide groove 421 under the pushing force of the lever 830. After the frame 10 is moved away, the third linear drive mechanism 410 drives the third platform 420 to rise to the initial position. The worker then puts a new empty frame 10 into the first guide groove 421 of the third platform 420 again, repeating the above lifting, insertion plate and lever process. The main purpose of the first guide groove 421 is to limit and guide the frame 10. On the one hand, during the placement of the frame 10, the first guide groove 421 can restrict the position of the frame 10 on the third platform 420, ensuring that when the worker places the empty frame 10 on the third platform 420, the frame 10 can be accurately and stably positioned in the preset position; on the other hand, when the frame-moving device 800 moves the frame 10, the first guide groove 421 provides a stable moving path for the frame 10, so that the frame 10 can be smoothly moved from the third platform 420 to the temporary storage plate 130 along the direction of the first guide groove 421, preventing the frame 10 from shifting or tipping over during the removal process.

[0031] refer to Figure 5 The temporary storage plate 130 is provided with a second guide groove 131, which is used to insert the rack 10 so that the rack 10 can move within the second guide groove 131. It can be understood that the inner wall of the second guide groove 131 can limit and guide the rack 10 on the temporary storage plate 130. When the rack 800 moves the rack 10 filled with PCBs from the first guide groove 421 of the third platform 420 to the temporary storage plate 130, the rack 10 can enter the second guide groove 131 of the temporary storage plate 130. The second guide groove 131 will restrict the movement direction of the rack 10 on the temporary storage plate 130, so that the rack 10 can move and be stored smoothly along the second guide groove 131, and prevent the rack 10 from shifting or tipping over on the temporary storage plate 130.

[0032] refer to Figure 8 and Figure 9 The PCB finished board 30 automatic insertion machine also includes a flipping device 900, which is located between the board picking station and the board pushing station 730. The board picking device 500 can transport the PCB at the board picking station to the flipping device 900, which is used to rotate the PCB 180°. The board picking device 500 can then transport the PCB on the flipping device 900 to the board pushing station 730. It can be understood that when a PCB needs to be flipped for insertion, the board picking device 500 first takes the PCB from the tray 20 at the board picking station. Instead of directly transporting it to the board pushing station 730, it transports the PCB to the flipping device 900 located between the board picking station and the board pushing station 730. After receiving the PCB, the flipping device 900 rotates the PCB 180°, changing the originally upward-facing side to the downward-facing side, thus meeting the specific insertion flipping requirements. After the PCB has completed a 180° flip, the board-retrieving device 500 operates again, removing the flipped PCB from the flipping device 900 and transporting it to the pusher 730 station. Subsequently, the pusher 730 device 700 will follow the standard pusher 730 process to push the PCB at the pusher 730 station into the corresponding slot 11 on the frame 10. When it is not necessary to flip the PCB, the board-retrieving device 500 can directly transport the PCB from the board-retrieving station to the pusher 730 station without going through the flipping device 900, flexibly adapting to different board insertion requirements.

[0033] In actual production, different PCBs may require flipping for insertion due to design requirements and subsequent process needs. The flipping device 900 can rotate the PCB 180°. When a PCB needs to be flipped for insertion, the board-taking device 500 can first transport the PCB to the flipping device 900 for flipping, and then send it to the pusher station 730 for insertion, perfectly adapting to these special insertion requirements. For cases where flipping is not required, the board-taking device 500 can directly transport the PCB from the board-taking station to the pusher station 730 without passing through the flipping device 900, thus not affecting the regular insertion process. This PCB finished board 30 automatic insertion machine has the ability to flexibly switch insertion methods, eliminating the need for additional dedicated equipment for different flipping requirements. This saves on equipment investment costs and allows for efficient processing of PCBs with different insertion requirements on the same production line, improving the equipment's versatility and production adaptability.

[0034] refer to Figure 9 The flipping device 900 includes a fifth linear drive mechanism 910, a fifth suction cup mechanism 920, a fifth rotary drive component 930, and a transfer table 940. The transfer table 940 and the fifth linear drive mechanism 910 are both mounted on the frame 100. The board picking device 500 can transport the PCB from the picking station to the transfer table 940. The output end of the fifth linear drive mechanism 910 is connected to the fifth rotary drive component 930, and the output end of the fifth rotary drive component 930 is connected to the fifth suction cup mechanism 920. The five linear drive mechanism 910 can drive the fifth rotary drive 930 and the fifth suction cup mechanism 920 to move in the left and right directions, so that the fifth suction cup mechanism 920 can move above the transfer table 940 and can adsorb the PCB on the transfer table 940. The fifth rotary drive 930 can drive the fifth suction cup mechanism 920 and the PCB to rotate 180°. The board picking device 500 can transport the PCB adsorbed by the fifth suction cup mechanism 920 to the pusher 730 station.

[0035] Understandably, when a PCB needs to be flipped 180°, the board-retrieving device 500 takes the PCB from the tray 20 at the board-retrieving station and transports it to the transfer platform 940 of the flipping device 900, completing the initial transfer of the PCB. Subsequently, the fifth linear drive mechanism 910 is activated, its output driving the fifth rotary drive component 930 and the fifth suction cup mechanism 920 connected to the fifth rotary drive component 930 to move left and right until the fifth suction cup mechanism 920 is precisely positioned above the transfer platform 940, directly facing the PCB on the transfer platform 940. Then, the fifth suction cup mechanism 920 generates suction force to hold the PCB on the transfer platform 940. After suction is complete, the fifth linear drive mechanism 910 adjusts the position of the fifth suction cup mechanism 920 to ensure stable subsequent flipping operations. Afterward, the fifth rotary drive component 930 is activated, its output driving the fifth suction cup mechanism 920 and the suctioned PCB to rotate together, precisely completing the 180° flipping action, thus flipping the PCB. After the flipping is complete, the board-retrieving device 500 moves again to the fifth suction cup mechanism 920, removes the PCB that has been flipped 180° from the fifth suction cup mechanism 920, and then transports it to the pusher 730 station to prepare for the subsequent board insertion operation of the pusher 730. After the fifth suction cup mechanism 920 releases the PCB, the fifth rotary drive component 930 can drive the fifth suction cup mechanism 920 to reset, and the fifth linear drive mechanism 910 can also drive the fifth rotary drive component 930 and the fifth suction cup mechanism 920 back to their initial positions, waiting for the next flipping operation.

[0036] In this embodiment of the invention, the first lifting and supporting device 200 includes a first linear drive mechanism and a first platform. The first linear drive mechanism is mounted on the frame 100, and its output end is connected to the first platform. The first platform supports stacked pallets 20, and the first linear drive mechanism drives the first platform to rise and fall, so that the stacked pallets 20 on the first platform can be sequentially raised to the pallet-retrieving station. The second lifting and supporting device 300 includes a second linear drive mechanism and a second platform. The second linear drive mechanism is mounted on the frame 100, and its output end is connected to the second platform. The second platform supports pallets 20, and the second linear drive mechanism drives the second platform to rise and fall, so that after the pallet-retrieving device 600 moves an empty pallet 20 from the pallet-retrieving station to the second platform, the second linear drive mechanism drives the second platform to descend a preset distance, so that the pallet-retrieving device 600 can smoothly place the next pallet 20 on the second platform, resulting in a stack of pallets 20 on the second platform. The first linear drive mechanism, the second linear drive mechanism, and the third linear drive mechanism 410 can all be common linear screw drive modules, which will not be described in detail here.

[0037] In this embodiment of the invention, the board picking device 500 includes a first multi-axis drive mechanism and a first suction cup mechanism. The output end of the first multi-axis drive mechanism is connected to the first suction cup mechanism. The first multi-axis drive mechanism is used to drive the first suction cup mechanism to move in the front-back direction, the left-right direction, and the up-down direction. The first suction cup mechanism is used to pick up or release the PCB, so that the first suction cup mechanism can transport the PCB, thereby enabling the first suction cup mechanism to transport the PCB from the board picking station to the transfer table 940 and the pusher station 730, and also enabling the first suction cup mechanism to transport the PCB from the fifth suction cup mechanism 920 to the pusher station 730. The second receiving cavity 120 is located to the right of the first receiving cavity 110. (Reference) Figure 2 The pallet-grabbing device 600 includes a second multi-axis drive mechanism and a second suction cup mechanism 610. The output end of the second multi-axis drive mechanism is connected to the second suction cup mechanism 610. The second multi-axis drive mechanism is used to drive the second suction cup mechanism 610 to move in the left-right and up-down directions. The second suction cup mechanism 610 is used to attract or release the pallet 20, so that the second suction cup mechanism 610 can move the pallet 20, thereby enabling the second suction cup mechanism 610 to move the pallet 20 from the pallet-grabbing station to the second platform. The first and second multi-axis drive mechanisms are common drive mechanisms, and the first and second suction cup mechanisms 610 are common suction cup gripping mechanisms, which will not be described further here.
