Abstract

This utility model relates to the field of circuit board surface mount assembly production line technology, and discloses a circuit board conveying device and a circuit board receiving platform. The circuit board conveying device includes a conveying mechanism, two vertical plates, and a lifting drive assembly. The conveying mechanism includes two conveying structure groups; these groups support and convey circuit boards. Conveying wheels and vertically movable vertical plates are arranged on the support plates of the conveying structure groups. When the vertical plates move up and down relative to the support plates, the arrayed support blocks on the vertical plates push the circuit boards on the conveying wheels upwards, away from the conveying wheels. During this process, multiple support blocks provide uniform multi-point support for the circuit boards, making the lifting process more stable and reliable, and reducing the probability of the circuit boards falling off the vertical plates. Furthermore, the lifting drive motor drives the vertical plates up and down through a gear-rack transmission, resulting in good vertical plate movement stability and further reducing the probability of the circuit boards falling off the vertical plates.

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 conveying device and a board storage docking platform. 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 board storage mechanism on the conveyor. As defective boards pass through, the storage mechanism picks them out and stores them, allowing removal without stopping the machine. However, current board storage transfer station solutions typically use cylinders to lift the circuit boards off the automated conveyor. Because the cylinder's power output is not smooth enough, the upward movement of the circuit boards is unstable, making them prone to falling off.

[0004] In summary, how to provide a board storage and transportation solution that reduces the probability of board drop during the storage process is an urgent problem to be solved in the field of PCB surface mount assembly production line technology. Utility Model Content

Furthermore, the lifting drive motor of this invention uses a gear-rack transmission to move the vertical plate up and down, ensuring smooth movement and further reducing the probability of the circuit board falling off.

[0043] Please see Figure 1 and Figure 2 This embodiment provides a board storage dock, which is applied in a circuit board surface mount assembly production line to transport circuit boards between two process devices and store defective circuit boards to prevent them from flowing into the next process device. The board storage dock includes a board conveying device, which mainly functions to transport circuit boards and store defective circuit boards. Of course, in addition to the board conveying device, the board storage dock also includes other components commonly used in related industries to support the automatic and stable operation of the board storage dock, such as a control unit 11, an electrical control system, and a housing 10. The control unit 11 can be a PLC controller, which is used to control the operation of the board storage dock, and the electrical control system is used to supply power to the board storage dock. The housing 10 is located outside the board conveying device to protect the board conveying device and to house the control unit 11 and the electrical control system. In addition to the components listed above, the board storage dock may also include other common components, which are not listed here.

[0044] Please combine Figures 2 to 8 In this embodiment, the circuit board conveying device includes a conveying mechanism, a storage rack, and a lifting drive assembly. The conveying mechanism is used to convey circuit boards and includes two conveying structure groups 20 and a conveying drive assembly. The two conveying structure groups 20 are arranged symmetrically and at intervals. Each conveying structure group 20 includes a support plate 70, which includes an inner sidewall. The inner sidewalls of the support plates 70 of the two conveying structure groups 20 are arranged opposite to each other. Multiple conveying wheels 221 are provided on the inner vertical walls 421 of the two support plates 70. The multiple conveying wheels 221 are arranged sequentially and at intervals along the conveying direction of the conveying mechanism. The multiple conveying wheels 221 can not only provide uniform multi-point support for the bottom surface of the circuit board, but also leave operating space between adjacent conveying wheels 221 for lifting the circuit board.

[0045] The storage rack includes two vertical plates 40, which are slidably mounted on the inner walls of two support plates 70. Each vertical plate 40 includes multiple support blocks 42, multiple oblong holes 43, and a rack structure 41. The support blocks 42 protrude from 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. 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 down to below the lowermost support block 42. Each conveying wheel 221 is located in the corresponding oblong hole 43. The oblong hole 43 can avoid the conveying wheel 221, preventing the conveying wheel 221 from affecting the vertical movement of the vertical plate 40, and also improving the compactness of the related structure. The rack structure 41 extends from top to bottom. Preferably, the rack structure 41 and the vertical plate 40 are integrally formed.

[0046] The lifting drive assembly includes a lifting drive motor 51, a first connecting shaft 55, and two connecting gears 54. The two ends of the first connecting shaft 55 are rotatably connected to two support plates 70. The two connecting gears 54 are respectively sleeved on the two ends of the first connecting shaft 55 and mesh with the rack structure 41 of the two vertical plates 40. The output end of the lifting drive motor 51 is connected to the first connecting shaft 55, and the lifting drive motor 51 can drive the two support plates 70 to move up and down synchronously via the connecting shaft.

[0047] The working process of this embodiment includes: when a defective circuit board is transported to the conveyor wheel 221, the lifting drive assembly drives the vertical plate 40 to rise relative to the support plate 70. The uppermost support block 42 of the vertical plate 40 pushes the defective circuit board away from the conveyor wheel 221 and stores the circuit board in the uppermost support block 42. When another defective circuit board is transported to the conveyor wheel 221, the vertical plate 40 continues to rise a preset distance. The support block 42 in the next row lifts the circuit board and stores it. In this way, until each row of support blocks 42 stores a circuit board, the cabinet door of the housing 10 is manually opened, the circuit board on the vertical plate 40 is taken out, and then an instruction is input to the control unit 11, so that the control unit 11 controls the lifting drive assembly to move the vertical plate 40 back to the initial position.

[0048] Compared with the prior art, in this embodiment, the support blocks 42 arranged in an array on the vertical plate 40 push the circuit board on the conveyor wheel 221 upward away from the conveyor wheel 221. During this process, the multiple support blocks 42 provide uniform multi-point support for the circuit board, making the lifting process of the circuit board more stable and reliable, and reducing the probability of the circuit board falling off the vertical plate 40. In addition, the lifting drive motor 51 in this embodiment drives the vertical plate 40 to move up and down through gear-rack meshing transmission, which makes the movement of the vertical plate 40 more stable, further reducing the probability of the circuit board falling off the vertical plate 40.

[0049] Next, we will further illustrate the structural scheme of this application with examples.

[0050] In some embodiments, the pallet receiving platform conveying device further includes a frame 30, which is disposed within the housing 10 of the pallet receiving platform. The frame 30 includes two symmetrically and spaced-apart mounting plates 31, which are fixed to the inner wall of the housing 10 by fasteners. Two support plates 70 are located between the two mounting plates 31. The two ends of a first connecting shaft 55 extend outward through the corresponding support plate 70 and the corresponding mounting plate 31, respectively. The first connecting shaft 55 is rotatably connected to the mounting plate 31 and provides support for the support plate 70.

[0051] In some embodiments, the lifting drive motor 51 is located on the side of the mounting plate 31 facing away from the vertical plate 40. The lifting drive motor 51 is fitted with a worm gear 52, and a worm wheel 53 is fitted on the first connecting shaft 55. The worm gear 52 meshes with the worm wheel 53, and the first connecting shaft 55 is driven by the worm gear 52 and worm wheel 53 transmission method, so that the rotation process of the first connecting shaft 55 is more stable and precise. Thus, the process of the first connecting shaft 55 driving the vertical plate 40 to move up and down through the gear-rack transmission method can also be more stable and precise.

[0052] In some embodiments, 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 extend outwards through corresponding support plates 70 and corresponding mounting plates 31, respectively. The two ends of the second connecting shaft 64 are rotatably connected to the two mounting plates 31, and the second connecting shaft 64 is rotatably connected to the two support plates 70 via the two second bearings. The second connecting shaft 64 provides support for the support plates 70. The two support plates 70 are suspended between the two mounting plates 31 via the first connecting shaft 55 and the second connecting shaft 64.

[0053] The radial cross section of the second connecting shaft 64 is polygonal, and the shape of the mounting hole of the second bearing is adapted to the shape of the second connecting shaft 64. By adopting this technical means, the second connecting shaft 64 can rotate relative to the support plate 70, and the support plate 70 can move relative to the first connecting shaft 55.

[0054] The conveying drive motor 61 and the lifting drive motor 51 are fixed to the same mounting plate 31 and located on the side of the mounting plate 31 facing away from the support plate 70. The output shaft of the conveying drive motor 61 is connected to the second connecting shaft 64 via a first pulley set. The two ends of the second connecting shaft 64 are connected to multiple conveying wheels 221 on the two support plates 70 via 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.

[0055] Furthermore, the first pulley assembly includes a first connecting pulley, a second connecting pulley, and a first connecting belt 62; the first connecting pulley is sleeved on the output shaft of the conveying drive motor 61, the second connecting pulley is sleeved on the second connecting shaft 64; and the first connecting belt 62 is sleeved on the first connecting pulley and the second connecting pulley.

[0056] 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.

[0057] In some embodiments, the conveying structure assembly 20 further includes a first conveyor belt 21 and a second conveyor belt 23. The first conveyor belt 21 and the second conveyor belt 23 are disposed on the support plate 70. The first conveyor belt 21, the plurality of conveyor wheels 221, and the second conveyor belt 23 are arranged sequentially along the conveying direction. The conveying drive assembly can drive the first conveyor belt 21, the plurality of conveyor wheels 221, and the second conveyor belt 23 to synchronously convey the circuit board in the forward and reverse directions along the conveying direction. Due to the inertia of the circuit board during its movement and the slippage between the circuit board and the conveyor wheels 221, the circuit board often cannot stop precisely on each conveyor wheel 221. For example, due to its own inertia, it may move beyond the bearing capacity of the conveyor wheel 221. In this case, the second conveyor belt 23 can support the circuit board and prevent it from falling. In addition, the second conveyor belt 23 and the conveyor wheels 221 can also convey the circuit board in the reverse direction, so that the circuit board is returned to the bearing capacity of each conveyor wheel 221, so as to stabilize the circuit board in the subsequent lifting. For example, due to slippage between the circuit board and the conveyor wheel 221, the circuit board cannot accurately enter the bearing range of each conveyor wheel 221. At this time, the circuit board is partially located on the first conveyor belt 21. Since the first conveyor belt 21 supports the circuit board, the circuit board will not fall off. In addition, the first conveyor belt 21 and the conveyor wheel 221 continue to transport the circuit board forward until the circuit board enters the bearing range of each conveyor wheel 221.

[0058] In some embodiments, the first conveyor belt 21 includes a first mounting base 212, two first tension 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 tension rollers 211 are located inside the first mounting base 212. The first conveyor belt 21 is sleeved on the two first tension rollers 211, and the circuit board is supported and conveyed by the first conveyor belt 213. A third connecting roller 82 is sleeved on the shaft of one of the two first tension 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 wheel 221. The third connecting roller 82 drives the corresponding first tension roller 211 to rotate, and the first tension roller 211 drives the first conveyor belt 213 to move, so that the first conveyor belt 213 can convey the circuit board.

[0059] The second conveyor belt 23 includes a second mounting base 233, two second tension 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 tension rollers 231 are located inside the second mounting base 233, and the second conveyor belt 23 is sleeved on the two second tension rollers 231. A fourth connecting roller 81 is sleeved on the shaft of one of the two second tension rollers 231, and a second connecting belt 63 is sleeved on the fourth connecting roller 81. This allows the fourth connecting roller 81 to rotate synchronously with the conveyor wheel 221. The fourth connecting roller 81 drives the corresponding second tension roller 231 to rotate, and the second tension roller 231 drives the second conveyor belt 232 to move, so that the second conveyor belt 232 can convey the circuit board.

[0060] Next, the structure of vertical plate 40 will be further illustrated by example.

[0061] In some embodiments, the support block 42 is integrally formed with the vertical plate 40, which improves the connection reliability between the support block 42 and the vertical plate 40 and prevents the support block 42 from shifting relative to the vertical plate 40 or even falling off the vertical plate 40 due to factors such as vibration, collision, and work fatigue after long-term operation.

[0062] In some embodiments, the support block 42 has an L-shaped bearing structure on the side facing away from the vertical plate 40. The bearing structure includes a vertical wall 421 and a transverse wall 422 extending from the bottom of the vertical wall 421 in the direction facing away from the vertical plate 40. During the process of lifting the circuit board, the transverse wall 422 abuts against the bottom surface of the circuit board to support and lift the circuit board, and the vertical wall 421 abuts against the side wall of the circuit board to prevent the circuit board from shifting position during the lifting process, thereby further reducing the probability of the circuit board falling.

[0063] In some embodiments, the vertical plate 40 has at least two sliders on the side facing the support plate 70. The two sliders are arranged side by side in the conveying direction. The support plate 70 has at least two slide rails, and the two sliders slide on the slide rails. The vertical plate 40 slides on the slide rails of the support plate 70 through the sliders, making the vertical movement of the vertical plate 40 more stable.

[0064] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0065] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
