[0001] This utility model belongs to the field of circuit board processing and production technology, and specifically relates to a circuit board loading and unloading device. Background Technology
[0002] In actual production, during the automated processing of existing flexible printed circuit boards (FPCs), the substrate is soft and easily deformed. During processes such as handling, positioning, pressing, drilling, and testing, bending, wrinkling, or displacement can easily occur, leading to decreased processing accuracy and low yield. Traditional production lines typically use independent loading, processing, and unloading units. Fixtures and supporting components (such as steel sheets) need to be manually or externally repositioned, resulting in long production cycles and low efficiency. Furthermore, the large number of fixtures required and the large space they occupy increase equipment and operating costs. Utility Model Content

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0036] See Figure 1-19 .
[0037] like Figure 1-5 As shown, this utility model provides a circuit board loading and unloading device, including a frame 1 and a fixture 6 movably mounted on the frame 1. The frame 1 is provided with a loading device 2, a unloading device 3, a processing unit 7 and a return device 4 disposed between the loading device 2 and the unloading device 3. The return device 4 and the processing unit 7 are arranged vertically and vertically respectively. The loading device 2 includes a loading mechanism 21 for placing the circuit board 5, a loading assembly 22 for loading and moving the fixture 6 to the processing unit 7, and a pick-and-place mechanism 24 for placing the steel sheet 8. The unloading device 3 includes an unloading mechanism 31 for taking out the processed circuit board 5, a loading assembly 32 for loading and moving the fixture 6 to the return device 4, and a pick-and-place mechanism 33 for picking up and placing the steel sheet 8. The return device 4 moves the fixture 6 and the steel sheet 8, which have detached from the circuit board 5, from the loading device 2 to the unloading device 3. In use, the fixture 6 is placed on the loading assembly 22. The feeding mechanism 21 places the unprocessed circuit board 5 onto the fixture 6. The pick-and-place mechanism 24 picks up the steel sheet 8 and places it onto the circuit board 5. The loading assembly 22 is activated, moving the fixture 6 with the circuit board 5 to the processing unit 7. The processing unit 7 processes the circuit board 5 and moves the fixture 6 with the processed circuit board 5 to the loading assembly 32. The pick-and-place mechanism 33 removes the steel sheet 8, and the unloading mechanism 31 removes the processed circuit board 5. Then, the pick-and-place mechanism 33 places the steel sheet 8 onto the fixture 6. The loading assembly 22 moves to the entrance of the processing unit 7, and the loading assembly 1 moves to the exit of the processing unit 7. The fixture 6, carrying the steel sheet 8, moves from the loading assembly 22 to the processing unit 7 and then from the processing unit 7 to the loading assembly 1 22. Next, the loading assembly 1 22 and the loading assembly 22 descend, and the pick-and-place mechanism 1 24 picks up the steel sheet 8 from the fixture 6. The feeding mechanism 21 moves the circuit board 5 onto the fixture 6 on the loading assembly 1 22. Then, the pick-and-place mechanism 1 24 places the steel sheet 8 onto the circuit board 5. This process is repeated to achieve continuous processing. Because the circuit boards processed by this device... 5 is a flexible circuit board 5. Its material is soft and easily bent, deformed, or wrinkled during handling and processing. This application addresses this by adding a pick-and-place mechanism and a steel sheet 8. After the circuit board 5 is placed into the fixture 6, the pick-and-place mechanism covers the circuit board 5 with the steel sheet 8. During the movement of the fixture 6 and processing unit 7 operations such as pressing, drilling, and testing, the steel sheet 8 provides a solid and flat reference surface for the flexible circuit board 5 below, effectively preventing deformation of the circuit board 5 due to external forces or its own weight, ensuring the accuracy of the processing position. Simultaneously, the precise fit between the steel sheet 8 and the fixture 6 provides a stable positioning platform for the flexible circuit board 5, preventing displacement during processing, thus significantly improving performance. The process yield is improved. After the circuit board 5 is processed and the empty fixture 6 and steel sheet 8 are removed by the return device 4, they can be automatically sent back from the unloading device 3 at the end of the production line to the loading device 2 at the front end without manual intervention or additional handling equipment for resetting. This makes the steps of loading, processing, unloading, and return of fixture 6 / steel sheet 8 seamlessly connected, forming a highly efficient automated cycle. This greatly reduces equipment waiting time and shortens the production cycle. The fixture 6 and steel sheet 8 are recycled within the system, eliminating the need to prepare a large number of turnover fixtures 6 and steel sheets 8, thus saving costs. In addition, the processing unit 7 and the return device 4 are set up vertically, making the whole device compact and space-saving.
[0038] Specifically, such as Figure 6-8As shown, the loading assembly 22 includes a mounting base 221 movably mounted on the frame 1 and a transmission assembly 222 mounted on the mounting base 221. The loading assembly 32 includes a mounting base 321 movably mounted on the frame 1 and a transmission assembly 322 mounted on the mounting base 221. The fixture 6 is mounted on the transmission assembly 222. The circuit board 5 moves with the fixture 6 to the processing unit 7 for processing under the action of the transmission assembly 222. The transmission assembly 322 receives the fixture 6 with the circuit board 5 transferred from the processing unit 7.
[0039] Furthermore, such as Figure 7 and Figure 10-11 As shown, the loading assembly 1 22 and loading assembly 2 32 also include a lifting assembly 23. The lifting assembly 23 drives the mounting base 1 221 to move back and forth between the first position 11 and the second position 12. The lifting assembly 23 drives the mounting base 2 321 to move between the third position 13 and the fourth position 14. The first position 11 and the third position 13 are at the same height. The second position 12 and the fourth position 14 are at the same height and are located at opposite ends of the return device 4. The height of the return device 4 is higher than the height of the processing unit 7. That is, the first position 11 and the second position 12 are a certain distance apart in vertical height, and the second position 12 is higher than the first position 11 in the Z-axis direction. The third position 13 and the fourth position 14 are a certain distance apart in vertical height (along the Z-axis direction), and the first position 11 and the third position 13 are a certain distance apart in horizontal position. At a fixed distance, during use, the loading component 22 moves along the Z-axis to the horizontal position of the feeding mechanism 21 / picking and placing mechanism 24 to receive the circuit board 5 / steel sheet 8, and moves to the second position 12 to receive the fixture 6; similarly, the loading component 22 moves along the Z-axis to the horizontal position of the unloading mechanism 31 / picking and placing mechanism 33 to remove the processed circuit board 5 / steel sheet 8, and moves to the fourth position 14 to transmit the fixture 6 with the steel sheet 8 to the return device 4. By precisely controlling the position of the loading component on the Z-axis, it can accurately stop at each workstation height where the feeding, unloading, picking and placing of steel sheet 8 and the return device 4 intersect, realizing precise transmission between different mechanisms, forming a smooth automated production line, avoiding complex oblique movements or position estimations, reducing cumulative errors and collision risks, and improving production efficiency.
[0040] Furthermore, such as Figure 7As shown, the lifting assembly 23 includes a drive component 231, a slider 232, and a slide rail 233 adapted to the slider 232. The slide rail 233 is mounted on the frame 1. The slider 232 is slidably connected to the slide rail 233. The mounting base 221 and the mounting base 321 are fixedly connected to the slider 232. The drive component 231 drives the slider 232 to move on the slide rail 233, causing the mounting base 221 to move back and forth between the first position 11 and the second position 12 and to drive the mounting base 321 to move between the third position 13 and the fourth position 14. The drive component 231 can be configured as a motor, a cylinder, or a lead screw. By designing the slider 232 and the slide rail 233, the movement of the mounting base 221 and / or the mounting base 321 is made smoother, improving the motion accuracy.
[0041] Specifically, such as Figure 8 As shown, the transmission assembly 222 and the transmission assembly 322 have the same structure, both including a belt 2221, a drive wheel 2222, a drive component 2223, and a connecting wheel 2224. The connecting wheel 2224 is fixedly connected to the mounting base 221 / mounting base 321. The output end of the drive component 2223 is connected to the drive wheel 2222. The belt 2221 is sleeved on the drive wheel 2222 and the connecting wheel 2224. The fixture 6 is placed on the belt 2221. The drive component 2223 drives the drive wheel 2222 to rotate, thereby driving the belt 2221 to rotate, and thus driving the fixture 6 to move. When the feeding mechanism 21 places the circuit board 5 on the fixture... When the load is 6, the second drive component 2223 is activated, and the first belt 2221 rotates to move the fixture 6 containing the circuit board 5. At this time, the fixture 6 is in the first position 11. The frame 1 has a slot 15 corresponding to the first position 11. The fixture 6 with the circuit board 5 moves from the slot 15 to the processing unit 7 via the first transmission component 222 to process the circuit board 5. The processing unit 7 includes a moving mechanism (not shown) for transporting and moving the fixture 6. The moving mechanism is at the same height as the first position 11 and the third position 13. The moving mechanism moves the fixture 6 from the first loading component 22 to the second loading component 32. The second transmission component 322 is activated to receive the fixture 6 with the circuit board 5 transferred from the processing unit 7.
[0042] Specifically, such as Figure 9-11As shown, the return device 4 includes a connecting frame 41 mounted on the frame 1 and a transmission assembly 42 mounted on the connecting frame 41. The return device 4 is at the same height as the second position 12 and the fourth position 14. The loading assembly 32 moves to the fourth position 14. The transmission assembly 32 receives the fixture 6 detached from the circuit board 5 and moves it to the loading assembly 22 located at the second position 12. The transmission assembly 32 includes a drive wheel 421, a belt 422, a drive member 423, and a connecting wheel 424 symmetrically arranged on the connecting frame 41. The belt 421... 22 is sleeved and connected to the second drive wheel 421 and the second connecting wheel 424. The second connecting wheel 424 is fixedly connected to the connecting frame 41. In use, the third drive component 423 drives the second drive wheel 421 to rotate, which in turn drives the second belt 422 to rotate, receiving the jig 6 transmitted from the second loading assembly 32. Then, the return device 4 transmits the jig 6 to the first loading assembly 22 located at the second position 12. The jig 6 is transmitted from the first belt 2221 of the second loading assembly 32 to the second belt 422 of the return device 4, and then to the first belt 2221 of the first loading assembly 22.
[0043] Furthermore, such as Figure 12-14 As shown, the feeding mechanism 21 includes a connecting block 211, a moving component 212, and a suction cup component 213. The connecting block 211 is slidably connected to the frame 1. The suction cup component 213 is detachably connected to the connecting block 211. Each moving component 212 includes a moving part 2121, a moving part 2122, and a moving part 2123. The moving part 2121 drives the suction cup component 213 to move along the Y-axis to achieve positioning with the fixture 6. The moving part 2122 drives the suction cup component 213 to rotate. The moving angle can be 360 degrees. The moving part 3 2123 drives the connecting block 1 211 to move along the X-axis, thereby moving the suction cup assembly 213 fixedly connected to the connecting block 1 211. By setting the suction cup assembly 213 along the X-axis and Y-axis, the suction cup assembly 213 can accurately position the fixture 6. The moving part 2 2122 is designed to allow the loading mechanism 21 to actively perform in-transit rotation correction after picking up the circuit board 5, so as to avoid the possibility of inconsistent angles of the circuit board 5 and ensure that the circuit board 5 can be placed on the fixture 6 at the correct angle.
[0044] Furthermore, such as Figure 12As shown, the suction cup assembly 213 includes a suction cup frame 2131 and a suction element 2132 disposed at the bottom of the suction cup frame 2131. In this embodiment, the suction element 2132 is a suction nozzle, which is arranged in a rectangular array on the suction cup frame 2131. The multiple suction nozzles work together to evenly distribute the suction force, effectively avoiding the problem that single-point suction may cause the circuit board 5 to bend locally or collapse and deform in the middle. like Figure 13 As shown, a feeding bin 16 is also provided on the frame 1. The feeding bin 16 includes a support frame 161 fixedly connected to the frame 1, a tray 162 for placing the circuit board 5, and a drive component 163 for driving the tray 162 to move up and down along the Z-axis. When using, such as Figure 13-15 As shown, the driving component 4 163 drives the pallet 1 162 to rise, causing the stacked circuit board 5 on the pallet 1 162 to move to the suction component 1 2132. The suction component 1 2132 aligns with the circuit board 5 under the driving movement of the moving component 1 2121, the moving component 2 2122, and the moving component 3 2123. After the circuit board 5 is sucked up, the driving component 4 163 drives the pallet 1 162 to reset. At this time, the suction component 1 2132 sucks up the circuit board 5. The moving component 1 2121 and the moving component 3 2123 drive the pallet 1 2132 to reach directly above the loading assembly 1 22 and align with the fixture 6. At this time, the driving component 1 231 drives the loading assembly 1 22 to rise, causing the fixture 6 placed on the belt 1 2221 to abut against the circuit board 5. The suction component 1 2132 releases the circuit board 5, and then the suction cup assembly 1 213 resets.
[0045] Specifically, such as Figure 14-16 As shown, the first pick-and-place mechanism 24 and the first loading assembly 22 are horizontally aligned in the Y-axis direction, and the second pick-and-place mechanism 33 is horizontally aligned in the Y-axis direction. The first pick-and-place mechanism 24 and the second pick-and-place mechanism 33 each include a connecting block 331, a driving component 7 332, and a suction component 333 disposed at the bottom of the connecting block 331. The connecting block 331 moves along the X-axis direction under the drive of the driving component 7 332. In use, when the unprocessed circuit board 5 is placed on the fixture 6 located on the loading assembly 22, the driving member 231 drives the loading assembly 22 to lift the circuit board 5 to the suction member 333 of the pick-and-place mechanism 24. The suction member 333 releases the sucked steel sheet 8 onto the circuit board 5 to press it down. Subsequently, the driving member 231 drives the loading assembly 22 to the first position 11, and the transmission assembly 222 is activated, moving the fixture 6 along with it to the first position 11. After the circuit board 5 and steel sheet 8 on fixture 6 are moved to processing unit 7, processing unit 7 processes circuit board 5. Then, fixture 6, carrying the processed circuit board 5 and steel sheet 8, is moved to mounting base 321 on loading assembly 32. Driving component 7 332 drives suction component 333 to move along the X-axis to directly above mounting base 321. Driving component 1 231 drives mounting base 321 to move upward to suction component 333, and suction component 333 picks up steel sheet 8.
[0046] Preferably, such as Figure 4 As shown, a visual positioning module 18 for visually positioning the circuit board 5 is provided between the feeding mechanism 21 and the loading component 22. The visual positioning module 18 is set on the frame 1. When the unprocessed flexible circuit board 5 arrives, its position and angle in the feeding bin 16 may have slight, unavoidable deviations. The visual positioning module 18 is like an "eye". After the feeding mechanism 21 picks up the circuit board 5 and places it in front of the fixture 6, it quickly scans and calculates the actual position and angle of the circuit board 5, compares the acquired image data with the preset ideal position, calculates the deviation value, and feeds it back to the moving component of the feeding mechanism 21 in real time so that it can make corresponding compensation movements. This forms a precise closed-loop control system to ensure that the circuit board 5 can be accurately placed in the final product.
[0047] like Figure 17-19 As shown, specifically, the unloading mechanism 31 includes a connecting block 311, a driving component 312, and a suction cup assembly 313. The connecting block 311 is mounted on the frame 1 and slidably connected to the frame 1. The suction cup assembly 313 is detachably connected to the connecting block 311. In this embodiment, the suction cup assembly 313 and the connecting block 311 are connected by screws. The suction cup assembly 313 includes a suction cup frame 3131 and a suction component 3132 mounted on the suction cup frame 3131. The output shaft of the driving component 312 is fixedly connected to the connecting block 311, driving the connecting block 311 to move along the X-axis, thereby moving the suction cup assembly 313 screwed to the connecting block 311. like Figure 3As shown, a feeding bin 17 is provided on one side of the loading assembly 32. The feeding bin 17 has the same structure as the loading bin 16 and is used to receive the processed circuit boards 5. In use, after the loading component 2 32 receives the fixture 6 with the processed circuit board 5, the driving component 1 231 drives the loading component 2 32 to rise along the Z-axis. At this time, the unloading mechanism 31 is located directly above the loading component 2 32. The circuit board 5 reaches the suction component 2 3132, which picks up the circuit board 5 and then moves along the X-axis under the action of the driving component 5 312 to directly above the unloading bin 17. At this time, the driving component 4 163 of the unloading bin 17 drives the pallet 1 162 to the suction component 2 3132 to receive the circuit board 5, and the suction component 2 3132 releases the circuit board 5.
[0048] The following is a detailed explanation of the working principle of this utility model; The loading mechanism 21 places the unprocessed circuit board 5 onto the fixture 6 of the loading assembly 22. The pick-and-place mechanism 24 covers the surface of the circuit board 5 with a steel sheet 8 to provide support and positioning. The loading assembly 22 transfers the fixture 6 containing the circuit board 5 and the steel sheet 8 to the processing unit 7 for processing. After processing, the loading assembly 32 receives the fixture 6 containing the processed circuit board 5. The pick-and-place mechanism 33 removes the steel sheet 8, the unloading mechanism 31 removes the processed circuit board 5, and then the pick-and-place mechanism 33 puts the steel sheet 8 back into the fixture 6. The second loading assembly 32 and the first loading assembly 22 move to the fourth position 14 and the second position 12 respectively under the action of the lifting assembly 23. The second loading assembly 32 transfers the empty fixture 6 carrying the steel sheet 8 to the return device 4 under the action of the lifting assembly 23. The return device 4 returns it to the first loading assembly 22. The first loading assembly 22 descends and resets. The feeding mechanism 21 places the new circuit board 5 again. The first picking and placing mechanism 21 covers the steel sheet 8 again, thus forming an uninterrupted automated processing cycle, which effectively improves the processing accuracy and production efficiency of the flexible circuit board 5.
[0049] The innovation of this utility model lies in the setting of a pick-and-place mechanism and a matching steel sheet. After the circuit board is placed into the fixture, the steel sheet is covered to provide a solid and flat reference surface for the flexible circuit board, effectively preventing bending, deformation and displacement during handling and processing. At the same time, the empty fixture and steel sheet are automatically returned from the unloading end to the loading end through the return device, realizing the internal recycling of the fixture and steel sheet within the system. No manual or external equipment intervention is required, forming an uninterrupted continuous processing flow. Moreover, the processing unit and the return device are arranged in a corresponding position, with a compact structure and reduced equipment footprint.
