AI Technical Summary
Existing waste circuit board recycling and processing conveying devices suffer from high labor intensity when handling large quantities of circuit boards, with manual placement being difficult and robotic arms having a low success rate in picking them up. Furthermore, the existing pallet structure cannot adapt to the needs of multiple rows or dynamically adjustable row spacing, resulting in low efficiency of the conveying system.
By employing arrangement components and a recognition-based secondary adjustment mechanism, components such as guide plates, cylinders, motors, and suction cups are used to achieve neat arrangement and orientation correction of circuit boards, ensuring that the circuit boards are transported along a fixed trajectory during the conveying process.
This achieves neat arrangement and uniform orientation of circuit boards, improves subsequent processing efficiency, meets different processing needs, and reduces the labor intensity of workers and the difficulty of gripping by robotic arms.

Description
Technical Field
[0001] This invention belongs to the field of waste circuit board recycling and processing technology, specifically a waste circuit board recycling and processing conveying device. Background Technology
[0002] Electric vehicle manufacturing generates waste circuit boards. Through proper recycling and reuse, companies can reduce raw material procurement costs while avoiding environmental pollution caused by indiscriminate discarding of circuit boards. Waste circuit board recycling and processing typically involves multiple stages such as crushing, sorting, and purification. Conveying devices can transport circuit boards from one processing stage to the next, ensuring continuous operation of the production line and improving processing efficiency.
[0003] Patent CN117416675B discloses a waste circuit board recycling and processing conveying device, relating to the field of waste circuit board recycling and processing technology. It includes a conveyor frame with two symmetrically rotating conveyor chains, and further includes: multiple sets of conveyor clamps, each set of which is positioned opposite to the two conveyor chains; a feeding mechanism located at the inlet end of the conveyor frame, which automatically locks and fixes the circuit boards placed on it; and a clamping adjustment mechanism located inside the conveyor frame and along the movement path of the multiple sets of conveyor clamps. This patent achieves passive clamping and fixing of the circuit boards by the conveyor clamps, while simultaneously driving the feeding mechanism to release the circuit boards, automatically transferring the circuit boards from the feeding mechanism to the conveyor clamps for secure conveying. This design is convenient to operate and significantly improves work efficiency.
[0004] However, the above technical solutions still have the following shortcomings in practical applications:
[0005] Circuit boards are transported by carrying them on pallets and securing them with clamps. While this method allows for the orderly transport of multiple circuit boards, when there are many discarded circuit boards, manually placing them one by one onto the pallet leads to high labor intensity for workers and is prone to placement errors due to human factors. On the other hand, if a robotic arm is used for automatic feeding, existing vision recognition systems struggle to accurately obtain the position information of each circuit board when they are piled up disorderly and overlapping, thus reducing the success rate of the robotic arm's gripping. Furthermore, existing pallet structures are mostly designed with a fixed spacing in a single row. When it is necessary to meet the process requirements of multi-row conveying (such as double or multiple rows) and dynamically adjusting the row spacing, their structural limitations prevent the conveying system from adapting to different processing needs.

[0039] The arrangement components include a guide rail 14 fixedly connected to one side of the frame 1, a support rod 15 slidably connected to the inner side of the guide rail 14, and multiple guide plates 21 arranged horizontally at equal intervals on the support rod 15. The leftmost guide plate 21 is fixedly connected to the end of the support rod 15, and the other guide plates 21 are slidably connected to the support rod 15. A guide block 24 is rotatably mounted on one end of the guide plate 21, and a telescopic block 25 is inserted into and slidably connected to the inner side of the guide block 24. An adjusting plate 60 is rotatably mounted on one end of the telescopic block 25. A cylinder is fixedly connected to one side of the frame 1. Cylinder 12 is fixedly connected to a baffle 13 at the piston end. One side of the baffle 13 is in contact with the end of the guide plate 21. Cylinder 22 is fixedly connected to one side of the frame 1. Baffle 29 is fixedly connected to the piston end of cylinder 22. One side of the baffle 29 is in contact with the end of the adjusting plate 60 and the guide plate 21. Guide rail 3 is fixedly connected to one side of the upper end of the frame 1. Guide rail 4 is slidably connected to one side of guide rail 3. Limiting plates 5 are slidably connected to both sides of guide rail 4. One end of the limiting plate 5 is in contact with one side of the baffle 13.
[0040] In this embodiment, as Figures 2-5 , Figure 12 , Figure 13 As shown, threaded rods 23 are rotatably installed at both ends of one side of guide rail 3. Motor 7 is fixedly connected to one end of guide rail 3. The output end of motor 7 is fixedly connected to one end of threaded rod 23. Bidirectional threaded rods 47 are rotatably installed at both ends of guide rail 4. Both sides of bidirectional threaded rods 47 are threadedly connected to limit plates 5. Motor 6 is fixedly connected to one end of guide rail 4. The output end of motor 6 is fixedly connected to one end of bidirectional threaded rod 47.
[0041] One end of the support rod 15 is threadedly connected to a threaded rod 17. Both ends of the threaded rod 17 are rotatably mounted on the guide rail 14. One end of the guide rail 14 is fixedly connected to a motor 18. The output end of the motor 18 is fixedly connected to one end of the threaded rod 17. The leftmost and rightmost guide plates 21 are rotatably mounted on one side of the upper end of the guide plate 21. The other guide plates 21 are rotatably mounted on one side of the upper end of the guide plate 21. One end of the connecting rod 58 is rotatably connected to one end of the connecting rod 57, and the ends of two adjacent connecting rods 57 are rotatably connected. One side of the support rod 15 is fixedly connected to an electric actuator 16. The piston end of the electric actuator 16 is fixedly connected to one side of the guide plate 21.
[0042] A cylinder 59 is fixedly connected to one side of the guide plate 21, and the piston end of the cylinder 59 is fixedly connected to one side of the adjusting plate 60.
[0043] Specifically, in existing technologies, circuit boards are carried on pallets and secured with clamps before being transported. While this method allows for the orderly transport of multiple circuit boards, when there are many discarded circuit boards, manually placing each board onto the pallet individually leads to high labor intensity for workers and is prone to placement errors due to human factors. On the other hand, if a robotic arm is used for automatic feeding, existing vision recognition systems struggle to accurately acquire the position information of each circuit board when they are stacked haphazardly and overlapping, thus reducing the success rate of the robotic arm's gripping. Furthermore, existing pallet structures are mostly designed with a single-row fixed spacing. When multi-row transport, such as double or multiple rows, and dynamically adjustable row spacing are required, the structural limitations of these pallet structures prevent the transport system from adapting to different processing needs.
[0044] Therefore, to solve the above problems, this embodiment is used for rectangular circuit boards of the same specifications in the same batch. The adjusting plate 60 and the guide plate 21 located on its left side together form the side wall of the conveying channel. According to the width of the circuit board, the cylinder 59 drives the adjusting plate 60 to move, adjusting the width of the conveying channel so that the width of the conveying channel is equal to the width of the circuit board. When the adjusting plate 60 moves, the telescopic block 25 slides relative to the guide block 24, and the guide block 24 and the telescopic block 25 rotate simultaneously. Then, the electric push rod 16 drives one side of the guide plate 21 to slide on the support rod 15. Under the transmission of the connecting rod 1 57 and the connecting rod 2 58, the remaining guide plates 21 also slide on the support rod 15, so that multiple support rods 15 can produce equidistant changes. After the distance between adjacent support rods 15 changes, the position of the adjusting plate 60 is adjusted again so that the width of the conveying channel is always equal to the width of the circuit board. Thus, the distance between two adjacent conveying channels can change while the width of the conveying channel remains unchanged. At the same time, the motor 18 drives the threaded rod 17 to rotate, causing the support rod 15 to slide on the guide rail 14, so that multiple conveying channels can move laterally at the same time. This allows for precise control of the position of the conveying channels on the conveyor belt 2 to meet different processing needs.
[0045] Then, cylinder 12 drives baffle 13 to rise and fall, adjusting the distance between the bottom of baffle 13 and the surface of conveyor belt 2 so that this distance is greater than the thickness of one circuit board but less than the thickness of two circuit boards. Then, according to the number of rows of circuit boards to be conveyed on conveyor belt 2, motor 6 drives bidirectional threaded rod 47 to rotate, adjusting the distance between the two limiting plates 5. At the same time, motor 7 drives threaded rod 23 to rotate, causing guide rail 4 to slide on guide rail 3, causing the two limiting plates 5 to move laterally, so that both limiting plates 5 are aligned with guide plate 21. At this time, the number of conveying channels between the two limiting plates 5 corresponds to the number of rows of circuit boards on conveyor belt 2.
[0046] Multiple circuit boards are placed between two limiting plates 5, and then the conveyor belt 2 is driven to run. When the conveyor belt 2 runs, it moves the circuit boards into the conveying channel. Since only one circuit board can pass through the channel opening at a time, overlapping or mutually obscuring circuit boards will be separated and pass through the channel opening one by one. Since the width of the channel opening is equal to the width of the circuit board, the width side of the circuit board that can pass through the channel opening is perpendicular to the adjusting plate 60. The circuit board whose width side is perpendicular to the adjusting plate 60 will gradually change direction under the continuous operation of the conveyor belt 2 until it can pass through the conveying channel opening.
[0047] The circuit boards that eventually enter the conveyor channels are arranged neatly, and are blocked by baffle 19. Once each conveyor channel is full of circuit boards, cylinder 22 lifts baffle 19, causing them to leave the conveyor channel and continue conveying. This transforms the originally disordered stack of circuit boards into a neatly arranged state, allowing them to be conveyed to the next process in fixed rows with controllable row spacing. This satisfies different processing requirements and improves subsequent processing efficiency.
[0048] In this embodiment, as Figure 2 , Figure 3 , Figures 6-11 As shown, a recognition-type secondary adjustment mechanism is also provided on the frame 1;

A motor 55 is fixedly connected to one side of the piston end of the cylinder 35. The output end of the motor 55 is fixedly connected to the positioning block 56.
[0052] An electric push rod 28 is fixedly connected to one side of the upper end of the connecting frame 11. The piston end of the electric push rod 28 is fixedly connected to one side of the frame 30. One end of the adjusting rod 40 is threadedly connected to a bidirectional threaded rod 42. Both ends of the bidirectional threaded rod 42 are rotatably mounted on the frame 30. A motor 9 41 is fixedly connected to one side of the frame 30. The output end of the motor 9 41 is fixedly connected to one end of the bidirectional threaded rod 42. Both ends of the adjusting rod 40 on one side are rotatably mounted to a bidirectional threaded rod 46. Both sides of the bidirectional threaded rod 46 are threadedly connected to one side of the slider 44. One end of the adjusting rod 40 is fixedly connected to a motor 10 45. The output end of the motor 10 45 is fixedly connected to one end of the bidirectional threaded rod 46. The sliders 44 on the left and right sides are connected by a telescopic rod 43.
[0053] A vacuum pump 36 is fixedly connected to one side of the frame 30. The air inlet of the vacuum pump 36 is connected to a connecting pipe 38. Multiple flexible hoses 39 are connected to the connecting pipe 38. One end of each flexible hose 39 is connected to one end of a rigid pipe 37.
[0054] A threaded rod 54 is threadedly connected to one side of the threaded block 53. Both ends of the threaded rod 54 are rotatably mounted on the slot plate 51. A motor 52 is fixedly connected to one end of the slot plate 51. The output end of the motor 52 is fixedly connected to one end of the threaded rod 54.
[0055] Specifically, in the above embodiments, although disordered stacked circuit boards can be arranged in a neat state, in some cases, the circuit board is a single-sided board with circuitry on only one side and a blank side on the other. The circuitry side has protrusions, while the blank side is relatively flat. When processing the circuit board in some steps, the circuitry side needs to be facing upwards and in a uniform orientation. However, in the above embodiments, when the circuit board is transported to the next step, its orientation is random, making it difficult for the processing steps to follow a fixed processing trajectory, thus significantly affecting processing efficiency.
[0056] Therefore, to solve the above problems, in this embodiment, according to the size of the circuit board, motor 9 41 drives bidirectional threaded rod 1 42 to rotate, and motor 10 45 drives bidirectional threaded rod 2 46 to rotate, so that adjusting rod 40 slides on frame 30 and slider 44 slides on adjusting rod 40, thereby adjusting the position of the four suction cups 48 so that the four suction cups 48 can be aligned with the four corners of the circuit board. When the circuit board in the conveying channel abuts against baffle 2 19, motor 4 20 drives threaded rod 1 9 to rotate, motor 7 26 drives threaded rod 4 27 to rotate, and electric push rod 2 28 drives frame 30 to rise and fall, thereby adjusting the position of the four suction cups 48 in the x, y, and z axis directions until the four suction cups 48 are in contact with the four corners of the circuit board. Under normal circumstances, there are no protrusions at the four corners of the circuit board, and the suction cups 48 can be tightly attached to the four corners of the circuit board surface. When cylinder 49 lowers pressure sensor 50 to contact the circuit board surface, pressure sensor 50 detects pressure. Then, it is driven away from the circuit board. Motor 52 drives threaded rod 54 to rotate, causing pressure sensor 50 to move laterally. It is then lowered again to contact the circuit board surface. If the smooth side of the circuit board faces upwards, the pressure detected by pressure sensor 50 occurs at the same time in both instances. Then, vacuum pump 36 extracts air from suction cup 48 to hold the circuit board in place and raise it until it is between the two positioning blocks 56. Then, cylinder 39... 5. The two positioning blocks 56 clamp the circuit board, and then the suction cup 48 releases the circuit board. Simultaneously, the motors 55 on both sides drive the positioning blocks 56 to rotate, causing the circuit board to flip so that the circuit board's line surface faces upwards. Then, the pressure sensor 50 is driven down again to contact the circuit board surface. Due to the irregular protrusions on the line surface, even when the line surface is upwards, the timing of pressure detection by the pressure sensor 50 varies depending on the circuit board's orientation. Furthermore, the timing of pressure detection varies depending on the position of the pressure sensor 50 when it contacts the circuit board. The position information of the circuit board can be obtained based on the timing of pressure detection by the pressure sensor 50, and this position information is transmitted to the control system. If the circuit board is oriented incorrectly, the motor 34 drives the gear 33 to rotate, causing the gear ring 32 to rotate, turning the circuit board around. Then, the suction cup 48 fixes the circuit board and returns it to its original position. This process is repeated, allowing the circuit boards in each conveying channel to be repositioned, and the repositioned circuit boards leave the conveying channel. This ensures that the circuit boards arriving at the processing stage face the same direction, allowing the processing stages to follow a fixed processing trajectory, which improves processing efficiency.
[0057] Working principle: The adjusting plate 60 and the guide plate 21 located to its left together form the side wall of the conveying channel. Based on the width of the circuit board, cylinder 59 drives the adjusting plate 60 to move, adjusting the width of the conveying channel to be equal to the width of the circuit board. When the adjusting plate 60 moves, the telescopic block 25 slides relative to the guide block 24, and the guide block 24 and telescopic block 25 rotate simultaneously. Then, electric actuator 16 drives one side of the guide plate 21 to slide on the support rod 15. Under the transmission of connecting rod 57 and connecting rod 58, the remaining guide plates 21 also slide on the support rod 15, causing multiple support rods 15 to change at equal intervals. After the spacing between adjacent support rods 15 changes, the position of the adjusting plate 60 is adjusted again to ensure that the width of the conveying channel is always equal to the width of the circuit board. Thus, the spacing between two adjacent conveying channels can change while the width of the conveying channel remains constant. Simultaneously, motor 318 drives threaded rod 217 to rotate, causing support rod 15 to slide on guide rail 414, allowing multiple conveying channels to move laterally simultaneously. This enables precise control of the conveying channel positions on conveyor belt 2 to meet different processing requirements. Then, cylinder 12 drives baffle 13 to rise and fall, adjusting the distance between the bottom of baffle 13 and the surface of conveyor belt 2. This distance is greater than the thickness of one circuit board but less than the thickness of two circuit boards. Based on the number of rows of circuit boards to be conveyed on conveyor belt 2, motor 16 drives bidirectional threaded rod 347 to rotate, adjusting the distance between two limiting plates 5. At the same time, motor 27 drives threaded rod 323 to rotate, causing guide rail 24 to slide on guide rail 3, causing the two limiting plates 5 to move laterally until both limiting plates 5 are aligned with guide plate 21. At this point, the number of conveying channels between the two limiting plates 5 corresponds to the number of rows of circuit boards on conveyor belt 2. Multiple circuit boards are placed between two limiting plates 5, and then the conveyor belt 2 is driven to operate. As the conveyor belt 2 operates, it moves the circuit boards into the conveyor channel. Since only one circuit board can pass through the channel opening at a time, overlapping or mutually obscuring circuit boards will separate and pass through the channel opening one by one. Because the width of the channel opening is equal to the width of the circuit board, the width side of the circuit board that can pass through the channel opening is perpendicular to the adjusting plate 60. Circuit boards whose width side is perpendicular to the adjusting plate 60 will gradually change direction under the continuous operation of the conveyor belt 2 until they can pass through the conveyor channel opening. The circuit boards that finally enter the conveyor channel are neatly arranged, and the circuit boards in the conveyor channel are blocked by the second baffle 19. When each conveyor channel is full of circuit boards, the second cylinder 22 drives the second baffle 19 to rise, thus leaving the conveyor channel and continuing to convey. This transforms the originally disordered stacked circuit boards into a neatly arranged state, and they are conveyed to the next process in a fixed number of rows with controllable row spacing, thereby meeting the needs of different processing steps and improving subsequent processing efficiency.Based on the size of the circuit board, motor 9 41 drives bidirectional threaded rod 1 42 to rotate, and motor 10 45 drives bidirectional threaded rod 2 46 to rotate, causing adjusting rod 40 to slide on frame 30 and slider 44 to slide on adjusting rod 40. This adjusts the position of the four suction cups 48 so that they can be aligned with the four corners of the circuit board. When the circuit board in the conveying channel abuts against baffle 2 19, motor 4 20 drives threaded rod 1 9 to rotate, motor 7 26 drives threaded rod 4 27 to rotate, and electric push rod 2 28 moves frame 30 up and down to adjust the position of the four suction cups 48 in the x, y, and z axes until the four suction cups 48 are in contact with the four corners of the circuit board. Normally, there are no protrusions at the four corners of the circuit board, and the suction cups 48 can fit tightly against the four corners of the circuit board surface. When cylinder 49 lowers pressure sensor 50 to contact the circuit board surface, pressure sensor 50 detects pressure. Then, it is driven away from the circuit board. Motor 52 drives threaded rod 54 to rotate, causing pressure sensor 50 to move laterally. It is then lowered again to contact the circuit board surface. If the smooth side of the circuit board faces upwards, the pressure detected by pressure sensor 50 occurs at the same time in both instances. Then, vacuum pump 36 extracts air from suction cup 48 to hold the circuit board in place and raise it until it is between the two positioning blocks 56. Then, cylinder 39... 5. The two positioning blocks 56 clamp the circuit board, and then the suction cup 48 releases the circuit board. Simultaneously, the motors 55 on both sides drive the positioning blocks 56 to rotate, causing the circuit board to flip so that the circuit board's line surface faces upwards. Then, the pressure sensor 50 is driven down again to contact the circuit board surface. Due to the irregular protrusions on the line surface, even when the line surface is upwards, the timing of pressure detection by the pressure sensor 50 varies depending on the circuit board's orientation. Furthermore, the timing of pressure detection varies depending on the position of the pressure sensor 50 when it contacts the circuit board. The position information of the circuit board can be obtained based on the timing of pressure detection by the pressure sensor 50, and this position information is transmitted to the control system. If the circuit board is oriented incorrectly, the motor 34 drives the gear 33 to rotate, causing the gear ring 32 to rotate, turning the circuit board around. Then, the suction cup 48 fixes the circuit board and returns it to its original position. This process is repeated, allowing the circuit boards in each conveying channel to be repositioned, and the repositioned circuit boards leave the conveying channel. This ensures that the circuit boards arriving at the processing stage face the same direction, allowing the processing stages to follow a fixed processing trajectory, which improves processing efficiency.
