Description

Technical Field

[0001] This utility model relates to the field of circuit board surface assembly production line technology, and in particular to a board storage docking station. Background Technology

[0002] Printed circuit boards, also known as PCBs, are used in surface mount assembly lines to mount or assemble components onto the surface of circuit boards. In PCB assembly lines, transfer tables are typically used to transport circuit boards between adjacent processing equipment.

[0003] Common transfer stations include automated conveyor systems that transport circuit boards from one workstation to the next. During production line operation, defective circuit boards often get mixed in, requiring removal to prevent them from flowing into the next process. To remove these boards, some transfer station solutions incorporate a storage mechanism on the conveyor. When a defective board passes through, the storage mechanism removes and stores it, allowing removal without stopping the machine. However, due to the inertia of the circuit board, it often moves excessively forward, preventing it from stopping within the preset position. This increases the risk of storage mechanism failure in removing the board.

[0004] In summary, how to provide a storage docking station solution that reduces the risk of storage failure is an urgent problem to be solved in the field of PCB surface mount assembly production line technology. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention employs a first conveying structure, a second conveying structure, and a third conveying structure to transport circuit boards. During operation, defective circuit boards are first transported to the third conveying structure. A first sensor detects the circuit board on the third conveying structure and generates a first sensing signal. Upon receiving the first sensing signal from the first sensor, the control unit controls the conveying drive assembly to reverse the transport of the circuit board through the second and third conveying structures. This continues until the first sensor stops sending the first sensing signal back to the control unit, indicating that the circuit board has left the third conveying structure and has been returned to the second conveying structure. Subsequently, the control unit controls a lifting drive motor to raise the storage rack, and a support structure pushes the circuit board from the second conveying structure upwards for storage. Using the aforementioned technical solution, this invention can transport circuit boards more accurately to the second conveying structure, allowing the storage rack to push the circuit board upwards and reduce the risk of storage rack failure.

[0023] Please combine Figures 1 to 8 This embodiment provides a board conveying platform for transporting circuit boards between two workstations and storing defective circuit boards. The conveying platform includes a frame 30 and an operating module mounted on the frame 30. The operating module includes a conveying mechanism, a storage rack, a lifting drive motor 51, a first sensor 101, and a control unit 11. The control unit 11 can be a PLC controller, an MCU controller, or other microcontrollers capable of controlling the operation of the equipment. The control unit 11 is electrically connected to the conveying mechanism, the lifting drive motor 51, and the first sensor 101 via wires to receive signals fed back from the first sensor 101 and control the operation of the lifting drive motor 51 and the conveying mechanism. In addition to the components listed above, the conveying platform may also include other common components, such as an electrical control system and an alarm device, which are not listed here.

[0024] The conveying mechanism includes a conveying drive assembly and two conveying structure groups 20, which are symmetrically arranged. Each conveying structure group includes a first conveying structure 21, a second conveying structure 22, and a third conveying structure 23 arranged sequentially along the conveying direction of the conveying mechanism. The first conveying structure 21, the second conveying structure 22, and the third conveying structure 23 are configured to support the circuit board. The conveying drive assembly is configured to drive the first conveying structure 21, the second conveying structure 22, and the third conveying structure 23 to convey the circuit board in the forward and reverse directions along the conveying direction.

[0025] The storage rack is movably mounted on the conveying mechanism and has a support structure. The output of the lifting drive motor 51 is connected to the storage rack via a linkage component. The lifting drive motor 51 is used to drive the storage rack to move up and down relative to the conveying mechanism. When the storage rack moves upward, the support structure can push the circuit board away from the second conveying structure 22 and store the circuit board.

[0026] The first sensor 101 is configured to sense the circuit board being transported to the third transport structure 23 and generate a corresponding first sensing signal. When the control unit 11 receives the first sensing signal from the first sensor 101, it can control the transport drive assembly to drive the second transport structure 22 and the third transport structure 23 to transport the circuit board in reverse. During the reverse transport of the circuit board, when the first sensor 101 stops feeding the first sensing signal back to the control unit 11, the control unit 11 controls the lifting drive motor 51 to drive the storage rack to rise, so that the support structure can push the circuit board returned to the second transport structure 22 upward away from the second transport structure 22.

[0027] The working process of the technical solution in this embodiment will be explained next in conjunction with application scenarios.

[0028] In some application scenarios where board storage is not required, the workflow includes: The previous station transports qualified circuit boards to the first conveyor structure 21. The first conveyor structure 21 then sends the circuit boards to the second conveyor structure 22, which in turn sends them to the third conveyor structure 23. A board exit sensor can be installed at the exit end of the third conveyor structure 23. When a circuit board is transported to the exit end of the third conveyor structure 23, the board exit sensor detects the circuit board, generates a corresponding sensing signal, and feeds this signal back to the control unit 11. Upon receiving the sensing signal, the control unit 11 controls the conveyor drive assembly to stop driving the first conveyor structure 21, the second conveyor structure 22, and the third conveyor structure 23, causing the circuit board to remain on the third conveyor structure 23, waiting for the next station's equipment to send a board exit signal to the control unit 11. Then, the third conveyor structure 23 sends the circuit board to the equipment at the next station. In some application scenarios that require board storage, the workflow includes: The equipment at the previous station transports the defective circuit board to the first conveying structure 21. The control unit 11 receives a signal that the circuit board is defective. This signal can be sent to the control unit 11 by the equipment at the previous station, or it can be provided by the detection component built into the circuit board receiving machine. For example, when the circuit board enters the first conveying structure 21, the scanning component, CCD camera or other detection equipment in the circuit board receiving machine scans the circuit board to determine whether the circuit board is qualified. If it is unqualified, an unqualified signal is generated and fed back to the control unit 11. After receiving a defective signal, the control unit 11 first controls the conveying drive assembly to drive the first conveying structure 21, the second conveying structure 22, and the third conveying structure 23 forward to convey the circuit board until the circuit board reaches the third conveying structure 23. The first sensor 101 detects the circuit board signal and feeds it back to the control unit 11. The control unit 11 then controls the conveying drive assembly to drive the first conveying structure 21, the second conveying structure 22, and the third conveying structure 23 in reverse to convey the circuit board until the sensor on the third conveying structure 23 no longer detects the circuit board signal, indicating that the circuit board has completely detached from the third conveying structure 23 and returned to the second conveying structure 22. At this point, the control unit 11 controls the lifting drive motor 51 to move the storage rack upward, pushing the circuit board away from the second conveying structure 22, thereby storing the circuit board above the second conveying structure 22. Using the aforementioned technical solution, this embodiment can more accurately convey defective circuit boards to the second conveying structure 22, so that the storage rack can push the circuit board away from the second conveying structure 22 from above, reducing the risk of storage rack failure in storing circuit boards.

[0029] In some embodiments, a second sensor is provided to prevent the defective circuit board from being partially or completely returned to the first conveying structure 21 during reverse conveying. The second sensor is configured to sense the circuit board on the first conveying structure 21 and generate a second sensing signal. During the reverse conveying of the circuit board, when the control unit 11 receives the second sensing signal fed back by the second sensor 102, the control unit 11 controls the conveying drive assembly to drive the first conveying structure 21, the second conveying structure 22, and the third conveying structure 23 to convey the circuit board in the forward direction until the first sensor 101 and the second sensor 102 stop feeding back the first and second sensing signals to the control unit 11. This indicates that the defective circuit board is completely located on the second conveying structure 22 and is completely supported by the second conveying structure 22. During the subsequent lifting of the circuit board by the storage rack, the risk of the circuit board becoming unbalanced and falling during the lifting process due to the circuit board's position deviating from the second conveying structure 22 can be reduced.

[0030] In some embodiments, the first sensor 101 is located between the two conveying structure groups 20 and below the inlet end of the third conveying structure 23. The inlet end of the third conveying structure 23 can be understood as the end of the third conveying structure 23 closer to the second conveying structure 22, while the end of the third conveying structure 23 furthest from the second conveying structure 22 is the outlet end of the third conveying structure 23. Specifically, the first sensor 101 is connected to the conveying structure group 20 via a connecting rod and is suspended below the inlet end of the third conveying structure 23. The first sensor 101 senses the circuit board in a non-contact manner, thus avoiding interference with the conveying process of the circuit board.

[0031] In some embodiments, the second sensor 102 is located between the two conveying structure groups 20 and below the output end of the first conveying structure 21. The output end of the first conveying structure 21 can be understood as the end of the first conveying structure 21 closer to the second conveying structure 22, while the end farther from the second conveying structure 22 is the input end of the first conveying structure 21. Specifically, the second sensor 102 is connected to the conveying structure group 20 via a connecting rod and is suspended below the output end of the first conveying structure 21. The second sensor 102 senses the circuit board in a non-contact manner, thus avoiding interference with the conveying process of the circuit board.

[0032] In some embodiments, the second sensor 102 and the first sensor 101 are aligned in the conveying direction of the conveying mechanism. This not only makes the structural layout neat, but also ensures that the first sensor 101 and the second sensor 102 can sense the same location on the circuit board, improving the consistency of their sensing signals and avoiding discrepancies in sensing results, such as one sensor sensing the circuit board while the other does not, or one sensor sensing the circuit board earlier while the other senses it later.

[0033] In some embodiments, the first sensor 101 and the second sensor 102 are both photoelectric sensors. Preferably, both are backlight-suppressing photoelectric sensors, which can avoid interference from the color of the circuit board and improve the accuracy of the sensing results.

[0034] Next, the structure and connection relationship of the storage rack and conveying structure group 20 will be illustrated by example: In some embodiments, the frame 30 includes two symmetrically and spaced-apart mounting plates 31. The two mounting plates 31 are fixed to the inner wall of the housing 10 by fasteners. Two guide rods 32 are provided between the two mounting plates 31, and the two guide rods 32 are arranged side by side along the conveying direction, with both ends of the guide rods 32 connected to the two mounting plates 31.

[0035] The conveying structure assembly 20 also includes a support plate 70, which is connected to a guide rod 32. Specifically, the guide rod 32 passes through the support plate 70, and the support plate 70 is suspended between two mounting plates 31 via the guide rod 32. The support plate 70 includes an inner sidewall, and the inner sidewalls of the support plates 70 of the two conveying structure assemblies 20 are opposite each other.

[0036] The storage rack includes two vertical plates 40, which are slidably mounted vertically on the inner sidewalls of the support plates 70 of the two conveying structure assemblies 20. Specifically, each vertical plate 40 has at least two sliders on the side facing the support plate 70. The sliders are fixed to the vertical plate 40 by fasteners and are arranged side by side along the conveying direction. Each support plate 70 has at least two slide rails on the side facing the vertical plate 40. The slide rails are connected to the support plate 70 by fasteners and have grooves. The two sliders are respectively engaged in the grooves of the two slide rails to slide in contact with the grooves.

[0037] The vertical plate 40 includes a rack structure 41 extending vertically. The linkage assembly includes a first linkage shaft 55, a worm gear 52, a worm wheel 53, and two linkage gears 54. The two ends of the first linkage shaft 55 are rotatably connected to two support plates 70. The two linkage gears 54 are respectively sleeved on the two ends of the first linkage shaft 55 and mesh with the rack structures 41 of the two support plates 70. A lifting drive motor 51 is fixed to the frame 30. The worm gear 52 is sleeved on the output shaft of the lifting drive motor 51, and the worm wheel 53 is sleeved on the first linkage shaft 55, meshing with the worm gear 52. The shaft of the lifting drive motor 51 drives the worm gear 52 to rotate, which in turn drives the worm wheel 53 to rotate. The worm wheel 53, through the first linkage shaft 55, drives the two linkage gears 54 to rotate. The two linkage gears 54 respectively drive the gear structures of the two vertical plates 40 to move vertically, thereby causing the corresponding vertical plates 40 to move vertically. In the aforementioned scheme, the lifting drive motor 51 can drive the first connecting shaft 55 to rotate relative to the support plate 70 more accurately and stably through the transmission of worm gear 53-worm 52. The vertical plate 40 is driven to move up and down by the transmission of connecting gear 54 and gear structure, so that the vertical plate 40 can move up and down more stably and accurately.

[0038] The support structure includes multiple support blocks 42 protruding from the two vertical plates 40. The multiple support blocks 42 are located on the side of the vertical plate 40 facing away from the support plate 70 and are arranged in an array. The support blocks 42 in each row are arranged at intervals along the conveying direction, and the support blocks 42 in each column are arranged at intervals along the vertical direction. The vertical plate 40 is provided with multiple oblong holes 43. An oblong hole 43 is provided between two adjacent columns of support blocks 42. The oblong hole 43 extends from above the uppermost support block 42 downward to below the lowermost support block 42. Each conveying wheel 221 is located in each oblong hole 43 in turn. When the vertical plate 40 moves upward, the uppermost support block 42 pushes the circuit board upward, causing the circuit board to be lifted away from the conveyor wheel 221, and the circuit board is temporarily stored on the uppermost support block 42. When another defective circuit board is conveyed to the conveyor wheel 221, the vertical plate 40 continues to move upward a preset distance, causing the next row of support blocks 42 to push the circuit board upward, causing the circuit board to be lifted away from the conveyor wheel 221 and stored on the row of support blocks 42. This process continues until all rows of support blocks 42 have stored circuit boards. The cabinet door on the housing 10 can be opened manually, the circuit boards on the storage rack can be manually removed, and then the reset button can be manually pressed to move the two vertical plates 40 of the storage rack downward to the initial state.

[0039] The support block 42 has an L-shaped load-bearing structure on the side facing away from the vertical plate. The load-bearing structure includes a vertical wall 421 and a horizontal wall 422. The horizontal wall 422 is used to abut against the circuit board, and the vertical wall 421 is used to limit the circuit board.

[0040] Next, the structural schemes of the first conveying structure 21, the second conveying structure 22, and the third conveying structure 23 will be further elaborated: In some embodiments, the second conveying structure 22 includes a plurality of conveying wheels 221 disposed on the inner sidewall of the support plate 70. The plurality of conveying wheels 221 are arranged sequentially and at intervals along the conveying direction of the conveying mechanism. Specifically, a rubber ring is fitted on the circumferential sidewall of the conveying wheel 221. The rubber ring can be made of a soft material such as rubber or silicone. The rubber ring is partially embedded in the circumferential sidewall of the conveying wheel 221, and the other part is exposed on the circumferential sidewall of the conveying wheel 221. The rubber ring can abut against the circuit board. When the conveying wheel 221 drives the rubber ring to rotate, the circuit board is conveyed forward by the friction between the rubber ring and the circuit board. To a certain extent, this can reduce the relative sliding between the circuit board and the conveying wheel 221, which affects the accuracy of the conveying wheel 221 in conveying the circuit board.

[0041] The conveying drive assembly includes a conveying drive motor 61, a second connecting shaft 64, two second bearings, a first pulley set, and two second pulley sets. The two ends of the second connecting shaft 64 are rotatably connected to two mounting plates 31, and the second connecting shaft 64 is rotatably connected to two support plates 70 via the two second bearings. The radial cross-section of the second connecting shaft 64 is polygonal, and the shape of the mounting holes of the second bearings matches the shape of the second connecting shaft 64. This technique allows the second connecting shaft 64 to rotate relative to the support plate 70, and also allows the support plate 70 to move relative to the first connecting shaft 55. The output shaft of the conveying drive motor 61 is connected to the second connecting shaft 64 via the first pulley set, and the two ends of the second connecting shaft 64 are connected to multiple conveying wheels 221 on the two support plates 70 via the two second pulley sets. When the conveying drive motor 61 drives the second connecting shaft 64 to rotate, the second connecting shaft can drive the multiple conveying wheels 221 on the two support plates 70 to rotate synchronously via the second pulley sets.

[0042] Specifically, the first pulley assembly includes a first connecting pulley, a second connecting pulley, and a first connecting belt 62; the first connecting pulley is mounted on the output shaft of the conveyor drive motor 61, and the second connecting pulley is mounted on the second connecting shaft 64; the first connecting belt 62 is mounted on the first connecting pulley and the second connecting pulley.

[0043] The second pulley assembly includes a first driving pulley, multiple first driven pulleys 65, a first connecting belt 62, and a second connecting belt 63. The first driving pulley is mounted on the second connecting shaft 64, and each first driven pulley 65 is correspondingly mounted on the shaft of each conveyor wheel 221. The first connecting belt 62 is mounted on each first driven pulley 65 and the first driving pulley. When the conveyor drive motor 61 rotates, it can drive the second connecting shaft 64 to rotate, and the second connecting shaft 64 drives the conveyor wheels 221 on the two support plates 70 to rotate synchronously.

[0044] In some embodiments, the first conveying structure 21 includes a first mounting base 212, two first tensioning rollers 211, and a first conveyor belt 213. The first mounting base 212 extends along the conveying direction, one end of the first mounting base 212 is fixed to the support plate 70, and the other end of the first mounting base 212 is suspended. The two first tensioning rollers 211 are located inside the first mounting base 212. The first conveyor belt 213 is sleeved on the two first tensioning rollers 211, and supports and conveys the circuit board by means of the first conveyor belt 213. A third connecting roller 82 is sleeved on the shaft of one of the two first tensioning rollers 211, and a second connecting belt 63 is sleeved on the third connecting roller 82. This allows the third connecting roller 82 to rotate synchronously with the conveyor roller 221. The third connecting roller 82 drives the corresponding first tensioning roller 211 to rotate, and the first tensioning roller 211 drives the first conveyor belt 213 to move, so that the first conveyor belt 213 can convey the circuit board.

[0045] The third conveying structure 23 includes a second mounting base 233, two second tensioning rollers 231, and a second conveyor belt 232. The second mounting base 233 extends along the conveying direction. One end of the second mounting base 233 is fixed to the support plate 70 on the side away from the first mounting base 212, and the other end of the second mounting base 233 is suspended. The two second tensioning rollers 231 are located inside the second mounting base 233, and the second conveyor belt 232 is sleeved on the two second tensioning rollers 231.
