[0039] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0040] like Figures 1 to 19 As shown, an embodiment of the present invention provides a PCB board conveying system, including a transfer station 400, a second conveying device 200, and a loading / unloading device. The transfer station 400 is configured to temporarily store PCB board boxes 53. The PCB board boxes are provided with multiple layers of temporary storage compartments, each of which contains PCB boards. The loading / unloading device is located at the transfer station 400 or the second conveying device 200. The loading / unloading device is used to transfer the PCB board boxes 53 between the second conveying device 200 and the transfer station 400. The second conveying device 200 is used to dock with the drilling machine workbench to convey PCB boards.

[0041] During the loading process, the loading and unloading device transfers the PCB board box 53 on the transfer station 400 to the second conveying device 200. After the drilling machine workbench is completed, the loading and unloading device transfers the PCB board box 53 on the second conveying device 200 to the transfer station 400.

[0042] In this embodiment, the loading and unloading device enables the transfer of PCB board bins between the second conveyor and the transfer station, eliminating the need to transport PCB boards one by one. Transporting the entire PCB board bin at once significantly reduces the number of transfers and time costs, substantially improving transfer efficiency. Furthermore, the second conveyor moves the PCB board bins to the drilling machine worktable, thus achieving automated docking between the transfer station and the drilling machine worktable.

[0043] Throughout the entire processing, the transfer station, the second conveyor, and the loading and unloading devices work together to form a continuous transfer process. This ensures that the connections between each link are tight and fast, reduces manual intervention in material handling and loading / unloading, improves transfer efficiency, avoids deviations that may occur during manual operation, ensures the accuracy of the PCB board during processing, and helps improve the processing quality and consistency of the product.

[0044] When the loading and unloading device is set in the transfer station 400, the PCB board box 53 is transferred to the second conveying device 200 by the loading and unloading device. The second conveying device 200 then moves the PCB board box 53 to the drilling machine workbench. The PCB board is then transported to the drilling machine workbench by a motion mechanism. The motion mechanism can be set on the second conveying device 200 or inside the PCB board box 53.

[0045] Alternatively, the loading and unloading device is set on the second conveying device 200. After the PCB board box 53 is transferred to the second conveying device 200 by the loading and unloading device, the second conveying device 200 drives the PCB board box 53 to the drilling machine worktable. The PCB board in the PCB board box can be transported to the drilling machine worktable by the loading and unloading device.

[0046] In one embodiment, the loading and unloading device includes a base 10, a conveying mechanism 20, and a first lifting mechanism 51. Multiple temporary storage bins are spaced apart within a PCB board material box 53 along a first direction. The conveying mechanism 20 and the PCB board material box 53 are mounted on the base 10 and spaced apart along a second direction. The first lifting mechanism 51 drives the conveying mechanism 20 and / or the PCB board material box 53 to move up and down in the first direction, so that the conveying mechanism 20 can dock with at least one temporary storage bin in the second direction, where the first direction (a) intersects with the second direction. The conveying mechanism 20 can output or input PCB boards into the temporary storage bins along the first direction.

[0047] The first lifting mechanism 51 can drive the conveying mechanism 20 to move up and down to adjust the height of the conveying mechanism 20; alternatively, the first lifting mechanism 51 can drive the PCB board bin 53 to move up and down to adjust the height of each temporary storage bin. Alternatively, the conveying mechanism 20 and the PCB board bin 53 can each be connected to a lifting mechanism.

[0048] In this embodiment, the first lifting mechanism 51 drives the conveying mechanism 20 and / or the PCB board bin 53 to move up and down, which can adjust the height of the conveying mechanism 20 and the height of each temporary storage bin, so that the conveying mechanism 20 is accurately connected with each temporary storage bin. By using the conveying mechanism 20 to load and unload PCB boards from multiple temporary storage bins, the PCB boards can be quickly and accurately sent from the temporary storage bins to the drilling machine worktable, or the PCB boards on the drilling machine worktable can be directly stored in the temporary storage bins, thereby improving the overall production efficiency.

[0049] In one embodiment, the conveying mechanism 20 includes a second driving member 24, a connecting beam 21, and a conveying assembly 22, with the conveying assembly 22 mounted on the connecting beam 21. During loading and unloading operations, the first lifting mechanism 51 can drive the connecting beam 21 and the conveying assembly 22 to move up and down, allowing the conveying assembly 22 to dock with the temporary storage bin.

[0050] The output end of the second drive component 24 is connected to the conveying component 22. When the conveying component 22 is connected to one of the temporary storage bins, the conveying component 22 can contact the material board. The second drive component 24 can move the conveying component 22 to drive the PCB board in the temporary storage bin to move along the second direction b, so as to send the PCB board out or store it in each temporary storage bin, thereby realizing the conveying of the material board.

[0051] In one embodiment, the conveying mechanism 20 further includes a first driving member 23. The output end of the first driving member 23 is connected to the connecting beam 21. The first driving member 23 can drive the connecting beam 21 to reciprocate along a first direction, thereby driving the conveying assembly 22 mounted on the connecting beam 21 to reciprocate along the first direction, so that the conveying assembly 22 can abut against or detach from the PCB board.

[0052] The output end of the second driving component 24 is connected to the conveying assembly 22. When the conveying assembly 22 comes into contact with the PCB board, the second driving component 24 can drive the conveying assembly 22 to move, thereby moving the PCB board along the second direction b, thus realizing the conveying of the PCB board. When the PCB board does not need to be conveyed, the conveying assembly 22 detaches from the PCB board and no longer contacts the PCB board. With the cooperation of the first driving component 23 and the second driving component 24, the conveying assembly 22 can directly feed the PCB board in the PCB board bin 53, which has a high loading and unloading efficiency.

[0053] In this configuration, the first direction a is perpendicular to the second direction b, where the second direction b is the X direction and the first direction a is the Z direction. In the PCB manufacturing field, in the second direction b, the conveying mechanism 20 is located between the PCB board material box 53 and the drilling machine worktable 500, enabling bidirectional transfer of PCB boards between the PCB board material box 53 and the drilling machine worktable 500.

[0054] In one embodiment, the connecting beam 21 includes two beam bodies 211, and the conveying assembly 22 includes two conveying members 221, both of which are disposed between the two beam bodies 211, with each conveying member 221 mounted on a corresponding beam body 211. The first driving member 23 is capable of driving at least one of the two beam bodies 211 to move along a first direction, so that the two conveying members 221 can clamp or release the PCB board.

[0055] When the two conveyors 221 clamp the PCB board, the second drive unit 24 can drive the two conveyors 221 to move, so as to move the PCB board along the second direction.

[0056] Since the two conveyor components 221 are respectively installed on the corresponding beams 211, the movement of the beams 211 will drive the conveyor components 221 to move synchronously. When the two beams 211 move closer to each other, the two conveyor components 221 also move closer, thereby clamping the PCB board; when the two beams 211 move away from each other, the two conveyor components 221 also move away from each other, thereby releasing the PCB board.

[0057] In this embodiment, by controlling the movement of the two beams 211 in the first direction a, the two conveying components 221 can clamp the PCB board, ensuring the stability of the PCB board during the conveying process in the second direction and preventing the PCB board from shifting or slipping during the conveying process.

[0058] In one specific embodiment, the first driving member 23 drives the two beams 211 to move towards or away from each other in a first direction, enabling the two conveying members 221 to move towards or away from each other. When clamping the PCB board, the two conveying members 221 simultaneously contact the PCB board, resulting in a more uniform force applied to the PCB board and better ensuring the stability of the PCB board in the clamped state. Alternatively, the first driving member 23 drives one of the beams 211 to move along the first direction, while the other beam 211 is fixed relative to the first driving member 23. The beam 211 connected to the first driving member 23 can drive its corresponding conveying member 221 to move closer to or away from the conveying member 221 on the other beam 211, thereby achieving the clamping and releasing of the PCB board.

[0059] As an example, the first lifting mechanism 51 is connected to the conveying mechanism 20. When the conveying mechanism 20 docks with the temporary storage bin, the first lifting mechanism 51 first moves the conveying mechanism 20 up and down, so that the conveying component 22 reaches the corresponding temporary storage bin. Then, the first driving member 23 drives at least one of the two beams 211 to move up and down, so that the two conveying components 221 can clamp or release the PCB board in the temporary storage bin. Alternatively, the first lifting mechanism 51 is connected to the PCB board bin 53. When the conveying mechanism 20 docks with the temporary storage bin, the first lifting mechanism 51 first moves the PCB board bin 53 up and down, so that the conveying component 22 can dock with one of the temporary storage bins. Then, the first driving member 23 drives at least one of the two beams 211 to move up and down, so that the two conveying components 221 can clamp or release the PCB board in the temporary storage bin.

[0060] After the two conveyor components 221 clamp the material plate, the conveying assembly 22 is driven to move by the second drive component 24, which in turn moves the material plate. With the cooperation of the first drive component 23 and the second drive component 24, the conveying assembly 22 delivers or feeds PCB boards out of the temporary storage bin, achieving high loading and unloading efficiency.

[0061] In one embodiment, the first driving member 23 includes two first sub-driving members 231, and the connecting beam 21 includes two beams 211. The output ends of the two first sub-driving members 231 are respectively connected to each beam 211. The first sub-driving members 231 are used to drive the corresponding beams 211 to move along a first direction, so that the two beams 211 move towards each other or away from each other in the first direction, thereby enabling the two conveying members 221 to clamp or release the PCB board.

[0062] The first sub-drive unit 231 includes at least a motor, a lead screw, and a lead screw seat. The output end of the motor is connected to the lead screw, and the lead screw seat is connected between the lead screw and the beam 211. Driven by the motor, it can drive the beam 211 to move up and down.

[0063] In one embodiment, the second driving member 24 includes two second sub-driving members 241. The output ends of the two second sub-driving members 241 are respectively connected to each of the conveying members 221. The second sub-driving members 241 are used to drive the corresponding conveying members 221 to move, so that the two conveying members 221 drive the clamped PCB board to move along the second direction b. The two second sub-driving members 241 are activated simultaneously, so that the two conveying members 221 keep the conveying synchronously, thereby ensuring that the PCB board can move smoothly along the second direction when it is clamped, without tilting or deflection.

[0064] In one embodiment, the conveying component 221 includes a mounting frame 2211, a first drive shaft 2212, and multiple sub-conveyors 2213. The mounting frame 2211 is connected to the beam 211, thereby connecting the conveying component 221 to the beam 211. The sub-conveyors 2213 are disposed on the mounting frame 2211, and the multiple sub-conveyors 2213 are interconnected via the first drive shaft 2212, which is connected to the output end of the second drive component 24. Further, the first drive shaft 2212 is connected to the output end of the second sub-drive component 241.

[0065] When the second drive unit 24 is started, it first transmits power to the first drive shaft 2212. Since multiple sub-conveyors 2213 are interconnected through the first drive shaft 2212, the first drive shaft 2212 transmits power from the second drive unit 24 to each sub-conveyor 2213, realizing the synchronous movement of multiple sub-conveyors 2213, thereby ensuring the stability of the PCB board during the conveying process.

[0066] In one embodiment, the second sub-drive unit 241 includes a motor and a transmission assembly. The transmission assembly is connected between the output end of the motor and the first drive shaft 2212. The motor can drive the first drive shaft 2212 to rotate through the transmission assembly, thereby driving the multiple sub-conveyors 2213 to move. The transmission assembly can be, but is not limited to, a belt drive assembly or a chain drive assembly.

[0067] In one embodiment, the sub-conveyor 2213 includes a first drive wheel 22131, a first belt 22132, and at least one first driven wheel 22133. The first drive wheel 22131 is mounted on a first drive shaft 2212, and the first driven wheel 22133 is mounted on a mounting bracket 2211. The first belt 22132 is wound around the first drive wheel 22131 and all the first driven wheels 22133. The first drive wheels 22131 of the multiple sub-conveyors 2213 are all mounted on the first drive shaft 2212, and the first drive wheels 22131 of the multiple sub-conveyors 2213 are spaced apart. The second drive member 24 can drive the first drive shaft 2212 to rotate, thereby driving the multiple first drive wheels 22131 to rotate, and thereby driving the first belts 22132 of the multiple sub-conveyors 2213 to move.

[0068] In each conveying assembly 22, the first belts 22132 of the two conveying members 221 move in opposite directions. When the two conveying members 221 clamp the PCB board, the two first belts 22132 directly contact the PCB board and apply the same force to the PCB board, thereby driving the PCB board to move along the first direction a.

[0069] In one embodiment, the number of sub-conveyors 2213 can be determined according to the size of the PCB board. Taking two sub-conveyors 2213 as an example, the first drive shaft 2212 passes through the mounting bracket 2211 and protrudes from the mounting bracket 2211 at both ends. The first drive wheel 22131 of one sub-conveyor 2213 is installed at one end of the first drive shaft 2212, and the first drive wheel 22131 of the other sub-conveyor 2213 is installed at the other end of the first drive shaft 2212.

[0070] As an example, the first direction 'a' is the Z direction, and the second direction 'b' is the X direction. The second drive unit 24 includes two second sub-drive units 241, which are referred to as "upper second sub-drive unit" and "lower second sub-drive unit" for ease of description. The conveying assembly 22 includes two conveying units 221, which are referred to as "upper conveying unit" and "lower conveying unit" for ease of description.

[0071] The output end of the upper second sub-drive unit is connected to the first drive shaft 2212 of the upper conveyor. The upper second sub-drive unit can drive the first drive shaft 2212 of the upper conveyor to rotate, thereby driving the first belts 22132 of the multiple sub-conveyors 2213 of the upper conveyor to move synchronously. The output end of the lower second sub-drive unit is connected to the first drive shaft 2212 of the lower conveyor. The lower second sub-drive unit can drive the first drive shaft 2212 of the lower conveyor to rotate, thereby driving the first belts 22132 of the multiple sub-conveyors 2213 of the lower conveyor to move synchronously.

[0072] The first belt 22132 of the upper conveyor moves in the opposite direction to the first belt 22132 of the lower conveyor. That is, when the first belt 22132 of the upper conveyor moves clockwise, the first belt 22132 of the lower conveyor moves counterclockwise. This allows the upper and lower belts to work together to move the PCB board along the second direction b.

[0073] In one embodiment, the conveying assembly 22 further includes a buffer 222, which is connected between the mounting frame 2211 of one of the conveying components 221 and the corresponding beam 211. That is, the buffer 222 can be connected between the mounting frame 2211 of the upper conveying component and the upper beam, or the buffer 222 can be connected between the mounting frame 2211 of the lower conveying component and the lower beam.

[0074] The buffer 222 is used to buffer when the conveyor 221 comes into contact with the PCB board, reduce the collision between the conveyor 221 and the PCB board, and reduce the damage to the PCB board that may be caused by excessive impact force.

[0075] In one embodiment, the buffer 222 includes a guide shaft 2221, a sliding sleeve 2222, and an elastic element. The sliding sleeve 2222 is connected to the beam 211, the guide shaft 2221 is connected to the mounting bracket 2211, the sliding sleeve 2222 is sleeved on the outside of the guide shaft 2221, and the elastic element is disposed between the outer peripheral surface of the guide shaft 2221 and the inner peripheral surface of the sliding sleeve 2222. When the conveyor 221 abuts against the PCB board, the reaction force on the mounting bracket 2211 is transmitted to the elastic element through the guide shaft 2221, causing the elastic element to deform and thus providing a buffering effect.

[0076] The elastic element can be, but is not limited to, a spring, a tension spring, or an elastic rubber component.

[0077] In one embodiment, such as Figure 3 , Figure 4 As shown, multiple PCB board bins 53 are arranged at intervals along a third direction, with the first, second, and third directions intersecting in pairs. The loading and unloading device can simultaneously drive multiple PCB board bins 53 to dock with the drilling machine worktable, further improving loading and unloading efficiency.

[0078] Multiple conveying components 22 are provided, and the connecting beam 21 extends along a third direction. The multiple conveying components 22 are spaced apart along the connecting beam 21, and each of the multiple conveying components 22 is correspondingly arranged with a multiple PCB board material bin 53. Each conveying component 22 can dock with each temporary storage compartment of the corresponding PCB board material bin 53. In this embodiment, each conveying component 22 can work independently and can realize the conveying operation of PCB boards in each temporary storage compartment of the PCB board material bin 53.

[0079] In one embodiment, a material box bracket 52 is provided on the base 10, and multiple PCB board material boxes 53 are placed on the material box bracket 52. The material box bracket 52 is slidably connected to the base 10 and connected to the output end of the first lifting mechanism 51. The first lifting mechanism 51 can drive the material box bracket 52 to move up and down, thereby driving multiple PCB board material boxes 53 to move up and down together, so as to realize the docking of each PCB board material box 53 with the corresponding conveying component 22.

[0080] In one embodiment, such as Figure 7 As shown, the material box bracket 52 includes a bracket body 521 and multiple support beams 522. The bracket body 521 includes a connecting plate 5211 and two lifting beams 5212. The lifting beams 5212 extend along a third direction c, and the support beams 522 extend along a second direction b. The multiple support beams 522 are spaced apart along the extension direction of the lifting beams 5212. Two adjacent support beams 522 form a support position for placing PCB board material boxes 53. Each PCB board material box 53 is placed on the corresponding support position.

[0081] Preferably, the support beam 522 includes a support body 5221 and a transition plate 5222. One end of the support body 5221 is mounted on one of the lifting beams 5212, and the transition plate 5222 is connected to the other end of the support body 5221 and the other lifting beam 5212. The transition plate 5222 is located below the support body 5221 in the vertical direction, so that it avoids the conveying component 22 when it moves up and down with the connecting beam 21, reducing the impact on the stroke of the conveying component 22.

[0082] In one embodiment, multiple second driving members 24 are provided, each capable of driving the corresponding conveying component 22 to move. Each second driving member 24 can independently drive the corresponding conveying component 22 to move, thereby improving the flexibility and adaptability of the entire conveying mechanism 20. In this case, each second driving member 24 includes two second sub-driving members 241. In each corresponding pair of conveying components 22 and second driving members 24, the output end of the upper second sub-driving member is connected to the first drive shaft 2212 of the upper conveying component, and the output end of the lower second sub-driving member is connected to the first drive shaft 2212 of the lower conveying component.

[0083] Alternatively, the second drive unit 24 can be configured such that multiple conveying components 22 are interconnected and can drive the multiple conveying components 22 to move simultaneously. In this case, the multiple conveying components 22 are interconnected through a specific transmission mechanism. After the second drive unit 24 is activated, it transmits power to one of the conveying components 22, and then transmits the power to the other conveying components 22 in sequence through the transmission mechanism, causing the multiple conveying components 22 to move simultaneously. This ensures that the movement of the multiple conveying components 22 has a certain degree of synchronicity, enabling them to work in coordination when conveying the material plate, maintaining the same conveying speed and direction of movement.

[0084] At this time, the second drive unit 24 includes two second sub-drive units 241. After the second drive unit 24 is started, the output end of the upper second sub-drive unit is connected to the first drive shaft 2212 of one of the upper conveyors, and is driven by a transmission mechanism to drive all the first drive shafts 2212 of the upper conveyors to rotate together. The output end of the lower second sub-drive unit is connected to the first drive shaft 2212 of one of the lower conveyors, and is driven by a transmission mechanism to drive all the first drive shafts 2212 of the lower conveyors to rotate together.

[0085] In one embodiment, the conveying mechanism 20 further includes a bracket 25 and a third drive member 26. A connecting beam 21 and a first drive member 23 are mounted on the bracket 25. The bracket 25 is movably connected to the base 10 along the second direction b. The connecting beam 21 is movably connected to the bracket 25 along the first direction a. The third drive member 26 can drive the bracket 25 to move along the second direction b, and drive the connecting beam 21 and the conveying assembly 22 to move together along the second direction b, so that the conveying assembly 22 can move between the PCB board box 53 and the drilling machine worktable 500 in the second direction b.

[0086] The third drive unit 26 can adjust the position of the conveying assembly 22 between the PCB board bin 53 and the drilling machine table 500. When conveying PCB boards to the drilling machine table 500, the third drive unit 26 drives the conveying assembly 22 towards the PCB board bin 53 so that the conveying assembly 22 can better contact the temporary storage bin. When the drilling machine table 500 unloads materials, the third drive unit 26 drives the conveying assembly 22 towards the drilling machine table 500 so that the conveying assembly 22 can better dock with the drilling machine table 500 and store the PCB boards in the PCB board bin 53.

[0087] The third driving component 26 includes at least a motor and a lead screw. The output end of the motor is connected to the lead screw, and the lead screw is connected to the bracket 25. The motor can drive the bracket 25 to move in the second direction.

[0088] In one embodiment, the bracket 25 includes two support plates 251, and the connecting beam 21 is located between the two support plates 251. Under the drive of the first driving member 23, the beam 211 can slide relative to the two support plates 251 in a first direction. Two third driving members 26 are provided, and the two third driving members 26 are connected to the two support plates 251 in a one-to-one correspondence. The stability of the connecting beam 21 in the second direction b is ensured by the joint drive of the two third driving members 26.

[0089] In one embodiment, two first driving members 23 are provided, and the two first driving members 23 are respectively mounted on two support plates 251. Each first driving member 23 includes two first sub-driving members 231. The upper beam is driven by the first sub-driving members 231 on the two support plates 251, and the lower beam is driven by the first sub-driving members 231 on the two support plates 251, thereby ensuring the stability of the movement of the two beams 211 in the first direction.

[0090] In one embodiment, the loading and unloading device further includes a tapping mechanism 40, which is mounted on the base 10 and located on the side of the PCB board bin 53 away from the conveying mechanism 20. The tapping mechanism 40 is used to position the PCB boards in multiple temporary storage bins along the second direction b, so that the multi-layer PCB boards in the PCB board bin are simultaneously aligned on the side away from the conveying mechanism 20. At the same time, when the multi-layer PCB boards are tapped by the tapping mechanism 40, the multi-layer PCB boards can be moved a certain distance toward the conveying assembly 22, which facilitates the two conveying components of the conveying assembly 22 to clamp the PCB boards.

[0091] In one embodiment, the striking mechanism 40 includes a fourth driving member 41 and a striking arm 42. The fourth driving member 41 can drive the striking arm 42 to approach the PCB board bin along the second direction b, so that the striking arm 42 can strike the PCB boards in multiple temporary storage bins. The positions of the multi-layer PCB boards in the temporary storage bins may differ. The striking arm 42 can strike and position the multi-layer PCB boards, so that the edges of the PCB boards can be accurately aligned.

[0092] The fourth driving component 41 includes at least a motor and a lead screw. The lead screw is connected to the racket arm 42, and the motor can drive the racket arm 42 to move.

[0093] In one embodiment, the clapping mechanism 40 further includes a mounting beam 43, a connecting rod assembly 44, and a fifth driving member 45. The mounting beam 43 is slidably connected to the base 10 along the second direction b. The clapping rod 42 is rotatably mounted on the mounting beam 43. The output end of the fourth driving member 41 is connected to the rotation shaft of the clapping rod 42. The fourth driving member 41 can drive the clapping rod 42 to move along the second direction b, so that the clapping rod 42 can move closer to or further away from the PCB board box.

[0094] The linkage assembly 44 is connected between the output end of the fifth drive member 45 and the flap arm 42. The fifth drive member 45 can drive the linkage assembly 44 to move and drive the flap arm 42 to rotate, so as to avoid the PCB board box when it enters or leaves the box bracket 52.

[0095] If the lever 42 remains stationary when the PCB board box enters or leaves the box holder 52, it may collide with the PCB board box. The linear motion of the output end of the fifth drive unit 45 is converted into the rotational motion of the lever 42 by the connecting rod assembly 44, so as to avoid the PCB board box and ensure that the PCB board box can smoothly enter and exit the box holder 52.

[0096] In one embodiment, such as Figure 1 , Figure 6As shown, the third direction c is the Y direction, and the mounting beam 43 extends along the third direction c. When multiple PCB board material boxes 53 are provided, the total number of striking arms 42 is at least the same as the total number of PCB board material boxes 53. The multiple striking arms 42 are spaced apart along the third direction c, and the multiple striking arms 42 correspond one-to-one with the multiple PCB board material boxes 53. The fourth driving component 41 can drive the multiple striking arms 42 to move along the second direction b, so that each striking arm 42 can strike the PCB board of the multiple temporary storage compartments of the corresponding PCB board material box 53. The rotation shafts of the multiple striking arms 42 are all mounted on the mounting beam 43. The output end of the fourth driving component 41 is connected to the rotation shaft of one of the striking arms 42. By driving one of the striking arms 42 through the fourth driving component 41, the mounting beam 43 can be driven to move along the second direction b, thereby driving the multiple striking arms 42 to move together along the second direction b, so that each striking arm 42 can strike and position the corresponding PCB board material box 53.

[0097] In one embodiment, the linkage assembly 44 includes a first linkage 441 and a second linkage 442, with the second linkage 442 connecting the paddle 42 and the first linkage 441. The paddle 42 is rotatably mounted on the mounting beam 43 about a first axis. One end of the second linkage 442 is connected to the paddle 42, and the other end of the second linkage 442 is rotatably connected to the first linkage 441 about a second axis. The first axis is parallel to the second axis and is the central axis of the rotation axis of the paddle 42.

[0098] The first connecting rod 441 is rotatably connected to the output end of the fifth driving member 45. The fifth driving member 45 is rotatably connected to the mounting beam 43. The fifth driving member 45 can drive the first connecting rod 441 to move, thereby causing the second connecting rod 442 to rotate around the second axis, which in turn causes the handle 42 to rotate around the first axis.

[0099] The end of the second link 442 closest to the first link 441 is rotatably connected to the first link 441 around a second axis, while the end of the second link 442 furthest from the first link 441 is connected to the striking arm 42. This end of the second link 442 can rotate around a first axis. When the second link 442 rotates, the trajectory of the end of the second link 442 closest to the first link 441 is arc-shaped, causing the position of the first link 441 to change in both the third direction c and the first direction. The second link 442 drives the striking arm 42 to rotate around the first axis, thereby avoiding the PCB board material box 53.

[0100] The fifth driving component 45 is a cylinder or a lead screw stepper motor, whose output end is capable of linear motion. Preferably, the third direction c is the Y direction, and the mounting beam 43 extends along the third direction c. The fixed end of the fifth driving component 45 is rotatably connected to the mounting beam 43, and the output end of the fifth driving component 45 is rotatably connected to the first connecting rod 441, so that the first connecting rod 441 can generate displacement in both the first direction and the third direction c as the second connecting rod 442 rotates.

[0101] In one embodiment, such as Figure 1 , Figure 6 As shown, multiple second links 442 are provided, and each second link 442 is connected to a corresponding racket handle 42. Each second link 442 is connected between the corresponding racket handle 42 and the first link 441, forming a four-bar linkage through the first link 441 and any two links. The fifth driving member 45 can drive the first link 441 to move, thereby causing the multiple second links 442 to rotate around their respective axes, thus causing the multiple racket handles 42 to rotate simultaneously.

[0102] The clapping mechanism 40 can be one or more. When there is one clapping mechanism 40, there is one first connecting rod 441, and all the second connecting rods 442 are connected to the first connecting rod 441 and spaced apart along a third direction. When there are multiple clapping mechanisms 40, the number of first connecting rods 441 is the same as the number of clapping mechanisms, and at least one second connecting rod 442 is connected to each first connecting rod 441, so that the total number of second connecting rods 442 should be at least the same as the total number of material boxes.

[0103] In one embodiment, the second conveying device 200 includes a self-moving chassis 201. The base 10 of the loading and unloading device is mounted on the self-moving chassis 201. The self-moving chassis 201 can drive the loading and unloading device to move, and can transfer the PCB board material box 53 temporarily stored on the transfer station 400 to the material box bracket 52 of the base 10. Then, the PCB board loading and unloading operation is realized through the conveying mechanism 20.

[0104] Among them, the self-moving chassis 201 can be an AGV (Automated Guided Vehicle).

[0105] In one embodiment, such as Figure 19 As shown, the PCB board material bin 53 includes a box body 531, a first positioning member 532, and a second positioning member 533. Multiple temporary storage compartments are disposed inside the box body 531 and spaced apart in a first direction. The first positioning member 532 is located at the top of the box body 531, and the second positioning member 533 is located at the bottom of the box body 531. The first positioning member 532 and the second positioning member 533 can be inserted and engaged to allow the box bodies 531 to be stacked. Multiple PCB board material bins 53 stacked together in the first direction can significantly increase the number of bins placed on the transfer station.

[0106] In the transfer process, multiple PCB board boxes 53 can be transferred to the second conveyor 200, which improves the overall transfer efficiency. Then, the drilling machine workbench is loaded with materials through the multiple PCB board boxes 53.

[0107] In this configuration, one of the first positioning element 532 and the second positioning element 533 is a positioning hole and the other is a positioning pin. Two of each of the first positioning element 532 and the second positioning element 533 are provided to prevent relative rotation between stacked boxes. Preferably, the first positioning element 532 is a positioning pin and the second positioning element 533 is a positioning hole.

[0108] In one embodiment, the transfer station 400 includes a second rack 401 and a plurality of second box supports 402. One end of each second box support 402 is connected to the second rack 401, and the second box support 402 is used to support at least one PCB board box 53. When the transfer station 400 docks with the second conveying device 200, the first lifting mechanism 51 drives the box bracket 52 to move up and down, which can cause the PCB board box 53 to detach from the second box support 402, or place the PCB board box 53 on the second box support 402.

[0109] Preferably, the second material box support 402 is a cantilever structure, and two adjacent second material box supports PCB board material boxes 53 together, and multiple PCB board material boxes 53 can be placed on the transfer station 400.

[0110] The bottom of the housing 531 is provided with a second positioning member 533, and the second material box support member 402 is provided with a fourth positioning member 403. The second positioning member 533 and the fourth positioning member 403 can be inserted and cooperated to limit the position of the PCB board material box 53 on the second material box support member 402, thereby realizing the positioning of the PCB board material box 53.

[0111] One of the second positioning component 533 and the fourth positioning component 403 is a positioning hole, and the other is a positioning pin. Two of each of the second positioning component 533 and the fourth positioning component 403 are provided to prevent the PCB board material box 53 from rotating relative to the second material box support component 402 on the horizontal plane.

[0112] Preferably, the second positioning element 533 is a positioning hole, and the fourth positioning element 403 is a positioning pin.

[0113] When the transfer station 400 docks with the second conveying device 200, the first lifting mechanism 51 drives the material box bracket 52 to move upward, causing the second positioning member 533 and the fourth positioning member 403 to disengage from each other. The first lifting mechanism 51 drives the material box bracket 52 to move downward, and the second positioning member 533 and the fourth positioning member 403 are aligned and inserted to position the PCB board material box 53, placing the PCB board material box 53 on the second material box support member 402.

[0114] In one embodiment, the PCB board conveying system further includes a first conveying device 100 and a hopper, the first conveying device 100 being used to transfer PCB board boxes 53 between the hopper and the transfer station 400.

[0115] The first conveying device 100 includes a transport vehicle 101, a second lifting mechanism 102, and at least one support arm 103. The second lifting mechanism 102 is mounted on the transport vehicle 101, enabling the first conveying device 100 to move on the ground. The support arm 103 can support at least one PCB board box 53. The output end of the second lifting mechanism 102 is connected to the support arm 103, and the second lifting mechanism 102 can drive the support arm 103 to move up and down, so that the support arm 103 can drive at least one PCB board box 53 to move up and down. By moving the support arm 103 through the second lifting mechanism 102, the height position of the support arm 103 can be adjusted, so that the PCB board box 53 can adapt to the material storage and handling needs at different heights.

[0116] When the transfer station 400 connects with the first conveying device 100, the second lifting mechanism 102 drives the support arm 103 to move up and down, which can drive the PCB board box 53 to detach from the second box support 402, or place the PCB board box 53 on the second box support 402.

[0117] In one embodiment, a fifth positioning member 104 is provided on the support arm 103, and a sixth positioning member 535 is provided inside the PCB board material box 53. The support arm 103 can extend into the interior of the box through an opening. The fifth positioning member 104 and the sixth positioning member 535 are inserted and engaged to limit the position of the PCB board material box 53 on the support arm 103. During the handling process, the position of the PCB board material box 53 on the support arm 103 can be locked by the cooperation between the fifth positioning member 104 and the sixth positioning member 535, preventing the PCB board material box 53 from slipping off the support arm 103.

[0118] The second lifting mechanism 102 drives the material box to move up and down through the support arm 103, so as to stack or split multiple PCB board material boxes 53. When the support arm 103 extends into the box body 531, under the drive of the second lifting mechanism 102, the support arm 103 can support the PCB board material box 53, realizing the suspended transportation of the PCB board material box 53.

[0119] In addition, a third positioning member 534 is provided at the bottom of the housing 531, and the support arm 103 can extend into the bottom of the housing 531, so that the fifth positioning member 104 and the third positioning member 534 can be inserted and engaged to limit the position of the PCB board box on the support arm 103. Driven by the second lifting mechanism 102, the support arm 103 can support the PCB board box 53, realizing the lifting and transporting of the PCB board box 53.

[0120] In this embodiment, the PCB board material boxes 53 are suspended and transported by the support arm 103. This allows the support arm 103 to extend into the interior of any layer of PCB board material boxes 53 when disassembling multiple stacked PCB board material boxes 53, without interfering with the stacking structure. When multiple PCB board material boxes 53 are stacked, the support arm 103 can be easily pulled out from the stacking structure without leaving specific positions at the bottom or top of the boxes, ensuring a tighter stacking of multiple PCB board material boxes 53 and reducing the possibility of shaking and displacement between them. The lifting and transporting of multiple PCB board material boxes 53 by the support arm 103 enables the transport of multiple stacked PCB board material boxes 53. By combining the suspension and lifting transport methods of the support arm 103, the transport of multiple stacked PCB board material boxes 53, as well as the disassembly and stacking of multiple PCB board material boxes 53 groups, can be realized.

[0121] Specifically, during the process of splitting and stacking multiple PCB board boxes 53, the first conveying device 100 moves the multiple PCB board boxes 53, and the second lifting mechanism 102 moves the support arm 103 downward and places the multiple PCB board boxes 53 on the transfer station 400. Then, the position of the lifting support arm 103 is adjusted so that the support arm 103 can extend into the interior of the topmost box. The support arm 103 continues to move upward, supporting the box and separating the topmost box from the stacked multiple PCB board boxes 53. The operation of splitting the boxes is repeated until the stacked multiple PCB board boxes 53 are separated and placed side by side on the transfer station 400. During stacking, the support arm 103 extends into the interior of one PCB board box 53, supports the PCB board box 53, and stacks the PCB board box 53 on top of other PCB board boxes 53, thus stacking the multiple PCB board boxes 53 on the transfer station 400 one by one.

[0122] In one embodiment, the silo further includes a buffer station, and the first conveying device 100 is used to transfer PCB board boxes 53 between the buffer station 300 and the transfer station 400.

[0123] The buffer station 300 includes a first rack 301 and multiple first bin supports 302. One end of each first bin support 302 is connected to the first rack 301, and the first bin support 302 is used to support at least one PCB board bin 53. The second lifting mechanism 102 drives the support arm 103 to move up and down, which can move the bin assembly away from the first bin support 302 or place the bin assembly on the first bin support 302.

[0124] Among them, the first material box support 302 is a cantilever structure, and two adjacent first material box supports PCB board material boxes 53 together. Multiple PCB board material boxes 53 can be placed on the buffer material station 300.

[0125] A second positioning element 533 is provided at the bottom of the housing 531, and a seventh positioning element 303 is provided on the first material box support 302. The second positioning element 533 and the seventh positioning element 303 can be inserted and engaged to limit the position of the PCB board material box 53 on the first material box support 302, thereby achieving the positioning of the PCB board material box 53. One of the second positioning element 533 and the seventh positioning element 303 is a positioning hole, and the other is a positioning pin. Two of each of the second positioning element 533 and the seventh positioning element 303 are provided to prevent the PCB board material box 53 from rotating relative to the first material box support 302 on the horizontal plane. Preferably, the second positioning element 533 is a positioning hole, and the seventh positioning element 303 is a positioning pin.

[0126] In practical applications, multiple PCB board boxes 53 are placed on two adjacent first box supports 302 at the buffer material station 300. At the transfer material station 400, one PCB board box 53 is placed on two adjacent second box supports 402.

[0127] The material handling process is as follows: the first conveyor 100 transports multiple stacked PCB board boxes 53 from the buffer station 300 to the transfer station 400. The second lifting mechanism 102 and support arm 103 then separate the stacked PCB board boxes 53 and place them one by one in the transfer station 400. The loading and unloading device transfers the boxes from the transfer station 400 to the second conveyor 200, which is connected to the drilling machine workbench 500. The loading operation is performed through the conveyor mechanism 20.

[0128] The material transfer process is as follows: the drilling machine workbench 500 has multiple workstations. The conveying mechanism 20 can store the PCB boards at each workstation in the corresponding PCB board material box 53. The second conveying device 200 moves to the transfer station 400 and places multiple PCB board material boxes 53 in the transfer station 400. After the second lifting mechanism 102 and the support arm 103 stack the multiple PCB board material boxes 53, the first conveying device 100 transports the stacked multiple PCB board material boxes 53 from the transfer station 400 to the buffer station 300.

[0129] Understandably, in order to ensure that the loading and unloading processes do not interfere with each other, the number of transfer stations 400 and buffer stations 300 is not limited to one.

[0130] In one embodiment, the hopper further includes an upper and lower PIN docking platform 600, and a first conveying device 100 is used to transfer PCB board boxes 53 between the upper and lower PIN docking platform 600 and the transfer station 400, or the first conveying device 100 is used to transfer PCB board boxes 53 between the upper and lower PIN docking platform 600 and the buffer station 300. The upper and lower PIN docking platform 600 serves as a transition and connection.

[0131] The PCB board conveying system also includes an upper pinning machine 700 and a lower pinning machine 800. An upper and lower pinning connection platform 600 is positioned between the upper pinning machine 700 and the PCB board bin 53, used to store the PCB boards output from the upper pinning machine 700 in the PCB board bin 53. Alternatively, the upper and lower pinning connection platform 600 is positioned between the lower pinning machine 800 and the PCB board bin 53, used to feed the PCB boards in the PCB board bin 53 one by one to the lower pinning machine 800. The first conveying device 100 can drive the PCB board bin 53 to move between the upper and lower pinning connection platform 600 and the buffer station 300, realizing automated operation of the upper and lower pinning processes.

[0132] Specifically, after the PIN machine 700 completes the PIN operation on the PCB board, the PCB board is stored in the PCB board bin 53 via the upper and lower PIN connection platform 600. The transport vehicle 101 moves between the upper and lower PIN connection platform 600 and the buffer station 300, storing the PCB board bin 53 in the buffer station 300. When the drilling machine worktable 500 needs to process the PCB board, the first conveyor device 100 transports multiple PCB board bins 53 from the buffer station 300 to the transfer station 400, where they are disassembled and placed side-by-side on the transfer station 400, thus transferring the PCB board bins 53 from the buffer station 300 to the transfer station 400. Next, the first lifting mechanism 51 of the loading / unloading device lifts the bin carrier 52, removing the multiple bins arranged side-by-side, and moves them to the drilling machine worktable 500 under the drive of the self-moving chassis. Upon arrival, the PCB board in the PCB board bin 53 is transported to the drilling machine worktable 500 by the conveying mechanism 20 of the loading and unloading device.

[0133] After the PCB board processing is completed, the conveying mechanism 20 of the loading and unloading device stores the processed PCB board in the PCB board bin 53, and moves it to the transfer station 400 driven by the self-moving chassis. Multiple PCB board bins 53 on the bin bracket 52 are then placed on the transfer station 400. Next, the first conveying device 100 stacks the multiple PCB board bins 53 arranged side-by-side on the transfer station 400 one by one, and then transports them to the buffer station 300. Finally, the first conveying device 100 transports the stacked multiple PCB board bins 53 or a single multiple PCB board bins 53 to the upper and lower pin connection platform 600, and the upper and lower pin connection platform 600 sends the PCB board to the pinning machine 800 for the final pinning operation, completing a full material cycle.

[0134] In one embodiment, the upper and lower PIN docking platform 600 includes a frame 60, a feeding mechanism 70, and a rotating mechanism 80; the rotating mechanism 80 and the feeding mechanism 70 are mounted on the frame 60.

[0135] The hopper has an opening, and the rotating mechanism 80 can drive the PCB board hopper 53 to rotate so that the opening faces or moves away from the feeding mechanism 70. By changing the direction of the opening, it is helpful to achieve the orderly flow of materials between different processes.

[0136] When the opening faces the feeding mechanism 70, the feeding mechanism 70 can drive the PCB board to move along the second direction b, so that the PCB board can enter and exit the PCB board bin 53 through the opening; when the opening faces away from the feeding mechanism, the first conveying device 100 drives the PCB board bin 53 to leave or enter the frame 60, and under the drive of the first conveying device 100, it can be transferred to the next process. By cooperating with the feeding mechanism 70 and the rotating mechanism 80, the processes of feeding, PCB board entry and exit from the bin, and bin loading and unloading can be realized, thereby realizing automated connection between different processes.

[0137] Furthermore, during the pinning process, after the pinning operation of the PCB board is completed, the rotating mechanism 80 drives the PCB board hopper 53 to rotate, so that the opening faces the feeding mechanism 70. The feeding mechanism 70 feeds the pinned PCB board into the PCB board hopper 53. After the PCB board hopper 53 is full, the rotating mechanism 80 drives the PCB board hopper 53 to rotate, so that the opening faces away from the feeding mechanism 70. At this time, the second lifting mechanism 102 of the first conveying device 100 can lift the PCB board hopper 53 away from the frame 60 and transport the PCB board hopper 53 to the buffer station 300.

[0138] During the pinning process, the PCB board bin 53 is transported onto the frame 60 by the first conveying device 100. The rotating mechanism 80 rotates the PCB board bin 53 so that its opening faces the feeding mechanism 70. The feeding mechanism 70 then feeds the PCB board to the pinning machine 800, which performs the pinning operation on the PCB board. After the PCB board bin 53 is empty, the rotating mechanism 80 rotates the PCB board bin 53 so that its opening faces away from the feeding mechanism 70. The first conveying device 100 then removes the empty PCB board bin 53. Once the PCB board bin 53 is fully loaded again, the above operation is repeated, thus achieving automated docking between the pinning machine 800 and the buffer station 300.

[0139] In one embodiment, such as Figure 13 As shown, the feeding mechanism 70 includes a receiving component 74, a support frame 71, a sixth driving component 72, and a clamping component 73. One end of the support frame 71 is connected to the frame 60, and the other end of the support frame 71 extends away from the frame 60 along the second direction b. The support frame 71 is a cantilever structure, and the feeding mechanism 70 is connected to the frame 60 through the support frame 71.

[0140] The receiving assembly 74 is mounted on the support frame 71, and the clamping component 73 is used to clamp the PCB board.

[0141] The receiving assembly 74 is used to receive the PCB board and move the PCB board along the second direction b toward the clamping member 73, so that the clamping member 73 can clamp the PCB board. By moving the PCB board through the receiving assembly 74, the PCB board can be moved to the clamping range of the clamping member 73, making it easier for the clamping member 73 to clamp the PCB board.

[0142] The sixth driving component 72 can drive the clamping component 73 to move along the second direction b, thereby driving the PCB board to enter and exit the material box along the second direction b. The clamping component 73 stably clamps the PCB board, and under the drive of the sixth driving component 72, the clamping component 73 is driven to move, thereby stably feeding the PCB board into or out of the material box.

[0143] In one embodiment, such as Figure 13 As shown, the support frame 71 includes two frames 711, a clamping member 73 is slidably connected between the two frames 711, and a sixth driving member 72 is installed on at least one of the two frames 711. The sixth driving member 72 can drive the clamping member 73 to move along the second direction b between the two frames 711. When the clamping member 73 drives the PCB board to move, the two frames 711 jointly bear the weight of the clamping member 73 and the PCB board. One or two sixth driving members 72 can be provided. When one sixth driving member 72 is provided, it is installed on one of the frames 711, and the clamping member 73 is driven by one sixth driving member 72. When two sixth driving members 72 are provided, one sixth driving member 72 is provided on each frame 711, and the two sixth driving members 72 jointly drive the clamping member 73.

[0144] Preferably, the vertical dimension of the frame 711 gradually increases along the second direction b toward the frame 60, thereby forming a stable support.

[0145] In one embodiment, such as Figure 14 As shown, the sixth driving component 72 includes a drive motor 721, a second driving pulley 722, a second driven pulley 723, and a synchronous belt 724. The drive motor 721 is fixedly mounted on the frame 711, and its output end is connected to the second driving pulley 722. The second driven pulley 723 is mounted on the frame 711 of the support frame 71. The synchronous belt 724 is wound around the second driving pulley 722 and the second driven pulley 723. The drive motor 721 can drive the second driving pulley 722 to rotate and can drive the synchronous belt 724 to transmit power. The synchronous belt 724 is connected to the clamping component 73, and since the clamping component 73 is slidably connected between the two frames 711, it can move in the second direction b under the drive of the drive motor 721.

[0146] In one embodiment, the receiving assembly 74 includes a ninth drive member 741 and a belt assembly 742. The ninth drive member 741 is mounted on the support frame 71. When receiving a PCB board, the PCB board is placed on the belt assembly 742. The ninth drive member 741 can drive the belt assembly 742 to move, thereby moving the PCB board placed on the belt assembly 742 toward the clamping member 73.

[0147] The belt assembly 742 includes a second belt 7421, a drive pulley 7422 and a driven pulley 7423. The second belt 7421 is wound around the drive pulley 7422 and the driven pulley 7423. The ninth drive member 741 can drive the drive pulley 7422 to rotate, thereby driving the second belt 7421 to move.

[0148] In one embodiment, such as Figure 13 As shown, the receiving assembly 74 also includes a transmission mechanism 743 and a second transmission shaft 744. The transmission mechanism 743 can be a common synchronous belt drive mechanism. There are two belt assemblies 742 connected by the second transmission shaft 744. The driving pulleys 7422 of the two belt assemblies 742 are mounted on the second transmission shaft 744, and the driven pulleys 7423 of the two belt assemblies 742 are mounted on the frame 711.

[0149] The input end of the transmission mechanism 743 is connected to the output end of the ninth drive member 741, and the output end of the transmission mechanism 743 is connected to the second drive shaft 744. Under the drive of the ninth drive member 741, the power is transmitted to the second drive shaft 744 through the transmission mechanism 743, which drives the second drive shaft 744 to rotate, thereby driving the two drive pulleys 7422 to rotate, realizing the synchronous movement of the two second belts 7421. The two second belts 7421 drive the PCB board to move along the first direction a.

[0150] In one embodiment, the clamping member 73 includes a transition plate 731, a seventh driving member 732, an eighth driving member 734, and a gripper 733. The transition plate 731 is slidably connected to the support frame 71, the output end of the sixth driving member 72 is connected to the transition plate 731, and the eighth driving member 734 is mounted on the transition plate 731.

[0151] The transition plate 731 can be slidably connected between the two frames 711 via a linear guide rail. The sixth driving member 72 directly drives the transition plate 731, causing the transition plate 731 to slide relative to the two frames 711, thereby enabling the clamping member 73 to slide relative to the two frames 711.

[0152] The seventh driving component 732 is connected to the transition plate 731. The seventh driving component 732 can drive the gripper 733 to release or clamp the PCB board. The seventh driving component 732 can drive the gripper 733 to be in an open or closed state. When the gripper 733 is open, it can release the PCB board. When the gripper 733 is closed, it clamps the PCB board.

[0153] The eighth driving component 734 can drive the gripper 733 to move along the first direction a, so as to avoid collisions when the receiving component 74 moves the PCB board toward the clamping component, ensuring that there is no collision or interference between the PCB board and the gripper 733, reducing material damage, and ensuring the smooth progress of the PCB board in the conveying and clamping process. The first direction a intersects with the second direction b, and preferably, the first direction a is a vertical direction.

[0154] In one embodiment, the gripper 733 includes a first gripper 7331 and a second gripper 7332. The first gripper 7331 and the second gripper 7332 are rotatably connected. The output end of the seventh drive member 732 is connected to the first gripper 7331. The second gripper 7332 is fixedly disposed relative to the transition plate 731. By driving the first gripper 7331 through the seventh drive member 732, the first gripper 7331 can be rotated relative to the second gripper 7332, thereby achieving precise control over the opening and closing degree of the gripper 733, and thus enabling the gripper 733 to release or clamp the PCB board.

[0155] In one embodiment, such as Figure 14 , Figure 15 As shown, the first gripper 7331 includes a first connecting portion 73311 and a first clamping portion 73312. The first clamping portion 73312 is installed at the end of the first connecting portion 73311 away from the transition plate 731. The second gripper 7332 includes a second connecting portion 73321 and a second clamping portion 73322. The second connecting portion 73321 is installed on the transition plate 731. The seventh driving member 732 is installed on the second connecting portion 73321. The second clamping portion 73322 is installed at the end of the second connecting portion 73321 away from the transition plate 731.

[0156] The first connecting part 73311 and the second connecting part 73321 are rotatably connected. The output end of the seventh driving member 732 is connected to the end of the first connecting part 73311 near the transition plate 731. The seventh driving member 732 drives the first connecting part 73311 to rotate relative to the second connecting part 73321, which can drive the first clamping part 73312 to move closer to or away from the second clamping part 73322, so as to clamp or release the PCB board.

[0157] When the seventh driving component 732 is activated, power is transmitted to the end of the first connecting part 73311 near the transition plate 731, causing the first connecting part 73311 to rotate around the rotational connection point with the second connecting part 73321. This rotation of the first connecting part 73311 drives the first clamping part 73312 to move accordingly, thereby adjusting the opening and closing range between the first clamping part 73312 and the second clamping part 73322. When the first clamping part 73312 is close to the second clamping part 73322, the PCB board is clamped between the first clamping part 73312 and the second clamping part 73322. When the first clamping part 73312 moves away from the second clamping part 73322, the PCB board is released.

[0158] It is understandable that the output end of the seventh drive unit 732 is rotatably connected to the first connecting part 73311.

[0159] Preferably, the seventh driving member 732 is a cylinder. The seventh driving member 732 can drive the end of the first connecting part 73311 near the transition plate 731 to move up and down. The rotational connection point between the first connecting part 73311 and the second connecting part 73321 acts as a fulcrum, allowing the first clamping part 73312 at the end of the first connecting part 73311 away from the transition plate 731 to also move up and down. When the seventh driving member 732 drives the end of the first connecting part 73311 near the transition plate 731 to move downwards, the first clamping part 73312 moves upwards, causing the first clamping part 73312 to move away from the second clamping part 73322, thus releasing the PCB board. When the seventh driving member 732 drives the end of the first connecting part 73311 near the transition plate 731 to move upwards, the first clamping part 73312 moves downwards, causing the first clamping part 73312 to move closer to the second clamping part 73322, thus clamping the PCB board.

[0160] Preferably, the eighth driving component 734 is a cylinder. The piston rod of the cylinder is connected to the transition plate 731, and the cylinder body is connected to the second connecting part 73321. Since the transition plate 731 is connected to the support frame 71 and remains stationary in the first direction a, during the extension and retraction of the piston rod, it will push the cylinder body of the cylinder to move in the first direction a, thereby driving the second connecting part 73321 to move in the first direction a, and finally realizing the movement of the gripper 733 as a whole in the first direction a, so as to achieve the effect of avoiding the PCB board.

[0161] In one embodiment, the second connecting portion 73321 has an L-shaped structure, having a horizontal section and a vertical section connected to each other. The vertical section is connected to the transition plate 731, and the seventh driving member 732 is mounted on the vertical section of the second connecting portion 73321. The horizontal section is rotatably connected to the first connecting portion 73311.

[0162] In one embodiment, such as Figure 13As shown, the feeding mechanism 70 also includes two clapping assemblies 75, with a support frame 71 located between the two clapping assemblies 75. The two clapping assemblies 75 are used for clapping and positioning the PCB board, and the clamping member 73 clamps the PCB board positioned by the clapping assemblies 75. By clapping and positioning the PCB board from both sides using the two clapping assemblies 75, the positional error of the PCB board during transportation can be effectively eliminated, ensuring that the PCB board is in the correct clamping position. After the clamping member 73 clamps the PCB board, it ensures that the PCB board will not shift position during subsequent movement.

[0163] During the feeding process, the receiving component 74 moves the PCB board along the second direction b, delivering it to the position between the two tapping components 75. The two tapping components 75 center the PCB board. Then, the clamping component 73 holds the PCB board, and under the drive of the sixth driving component 72, the PCB board continues to move along the second direction b. Through the cooperation of the receiving component 74, the clamping component 73, and the two tapping components 75, the PCB board is successfully conveyed.

[0164] In one embodiment, such as Figure 13 As shown, the clapper assembly 75 includes a tenth driving member 751 and a clapper 752. The tenth driving member 751 can drive the clapper 752 to move. The clappers 752 of the two clapper assemblies 75 can move towards each other or away from each other. When the two clappers 752 move towards each other, they can simultaneously clamp the PCB board, position the PCB board, and eliminate positional errors of the PCB board. When the two clappers 752 move away from each other, after releasing the PCB board, the clamping member 73 clamps the PCB board.

[0165] The tenth driving component 751 includes a lead screw stepper motor and a lead screw. The lead screw stepper motor converts rotational motion into linear motion internally, enabling linear relative motion between the lead screw and the lead screw stepper motor. The lead screw stepper motor is mounted on the clapper plate 752. One end of the lead screw is connected to the lead screw stepper motor, and the other end is mounted on the frame 711. Driven by the lead screw stepper motor, the lead screw stepper motor can move relative to the lead screw towards the frame 711, thereby driving the clapper plate 752 to move together, thus realizing the opposite or opposite movement of the two clapper plates 752.

[0166] In one embodiment, such as Figure 13 As shown, the clapper assembly 75 also includes two guide connecting shafts 753. One end of each guide connecting shaft 753 is connected to the frame 711, and the other end is slidably connected to the clapper 752. The movement of the clapper 752 is guided by the two guide connecting shafts 753.

[0167] In one embodiment, the upper and lower PIN docking platform 600 further includes a third lifting mechanism 62, which is mounted on the frame 60. The third lifting mechanism 62 can drive the feeding mechanism 70 to move up and down. The feeding mechanism 70 can dock with each storage layer so that the feeding mechanism 70 can move the PCB board into and out of each temporary storage bin.

[0168] For multiple stacked PCB board boxes 53, the third lifting mechanism 62 drives the feeding mechanism 70 to move up and down, so that the feeding mechanism 70 can load and unload each PCB board box 53.

[0169] The third lifting mechanism 62 is driven by a conventional motor + belt or motor + synchronous belt. The support frame 71 and the frame 60 can be slidably connected by a linear guide rail, which guides the vertical movement of the feeding mechanism 70.

[0170] In one embodiment, such as Figure 16 , Figure 17 As shown, the upper and lower PIN docking platform 600 also includes a fourth lifting mechanism 30. A material box bracket 61 is provided on the frame 60. The fourth lifting mechanism 30 is installed on the material box bracket 61. The output end of the fourth lifting mechanism 30 is connected to the rotating mechanism 80. The fourth lifting mechanism 30 can drive the rotating mechanism 80 to move up and down, so that the PCB board material box 53 can be detached from the material box bracket 61 or placed on the material box bracket 61.

[0171] When the hopper detaches from the hopper support 61, the hopper support 61 will not interfere with the rotation of the PCB board hopper 53. The PCB board hopper 53 is rotated by the rotation mechanism 80, causing the PCB board hopper 53 to switch between a first position and a second position. In the first position, the opening faces the feeding mechanism 70, and in the second position, the opening faces away from the feeding mechanism 70.

[0172] The fourth lifting mechanism 30 is a cylinder. At least one fourth lifting mechanism 30 is provided.

[0173] In one embodiment, the hopper also has a third position and a fourth position. When the hopper is in the third position, the opening faces the feeding mechanism 70, and when the hopper is in the fourth position, the opening faces away from the feeding mechanism 70.

[0174] The fourth lifting mechanism 30 can drive the rotating mechanism 80 and the PCB board box 53 to lift and lower, so that the PCB board box 53 can switch between the first position and the third position, and between the second position and the fourth position. In the first and third positions, the openings face the feeding mechanism 70. In the second and fourth positions, the openings face away from the feeding mechanism 70.

[0175] The rotating mechanism 80 can drive the PCB board hopper 53 to rotate, allowing the PCB board hopper 53 to switch between a third position and a fourth position. Vertically, the first and second positions are at the same height, as are the third and fourth positions. The fourth position is above the second position, and the third position is above the first position. The switching between these positions is achieved by the fourth lifting mechanism 30, which lifts and lowers the PCB board hopper 53. In the first and second positions, the PCB board hopper 53 rests on the hopper support 61. In the third and fourth positions, the PCB board hopper 53 can detach from the hopper support 61.

[0176] Taking the PIN process as an example, the position change of the PCB board 53 is as follows: the first conveying device 100 transports the empty PCB board 53 to the PCB board support 61. At this time, the PCB board 53 is in the second position. The fourth lifting mechanism 30 drives the PCB board 53 to rise, so that the PCB board 53 is separated from the PCB board support 61 and moves from the second position to the fourth position. The rotating mechanism 80 drives the PCB board 53 to rotate, so that the PCB board 53 switches from the fourth position to the third position. Finally, the fourth lifting mechanism 30 drives the PCB board 53 to fall down, and the PCB board 53 falls back onto the PCB board support 61, so that the PCB board 53 moves from the third position to the first position. The posture change of the PCB board 53 is completed.

[0177] In one embodiment, the fourth lifting mechanism 30 includes a lifting drive 32, a base plate 31, and a lifting platform 33. The base plate 31 is mounted on the material box bracket 61, the lifting drive 32 is mounted on the base plate 31, the output end of the lifting drive 32 is connected to the lifting platform 33, and the rotating mechanism 80 is mounted on the lifting platform 33. The lifting drive 32 drives the lifting platform 33 and the rotating mechanism 80 to move up and down. After the PCB board material box 53 is separated from the material box bracket 61, the rotating mechanism 80 drives the PCB board material box 53 to rotate, so that the opening of the PCB board material box 53 faces different directions.

[0178] The lifting drive component 32 includes at least one cylinder, and the extension rod of the cylinder is connected to the lifting platform 33. All the cylinders work together to drive the lifting platform 33 to move up and down.

[0179] In one embodiment, the lifting drive component 32 is installed below the base plate 31. When the output end of the lifting drive component 32 is connected to the lifting platform 33, the output end of the fourth lifting mechanism 30 can pass through the base plate 31 and connect to the lifting platform 33. A plurality of guide components 85 are provided between the lifting platform 33 and the base plate 31, and the lifting drive component 32 drives the lifting platform 33 to move up and down, and the multiple guide components 85 provide guidance.

[0180] In one embodiment, such as Figure 16 , Figure 17 As shown, the rotating mechanism 80 includes a rotating motor 81, a rotating shaft 82, and a rotating platform 83. The rotating motor 81 is mounted on the lifting platform 33, and the rotating shaft 82 is connected between the output end of the rotating motor 81 and the rotating platform 83. The rotating motor 81 can drive the rotating shaft 82 to rotate, thereby driving the rotating platform 83 to rotate. The rotating platform 83 is used to place the PCB board material box 53, so that the opening faces the feeding mechanism 70 or is away from the feeding mechanism 70.

[0181] In one embodiment, a first positioning pin 84 is provided on the rotating platform 83. When the fourth lifting mechanism 30 drives the rotating mechanism 80 to move upward, the first positioning pin 84 can be inserted and cooperate with the third positioning member 534 at the bottom of the PCB board material box 53 to limit the position of the PCB board material box 53 on the rotating platform 83 and improve the stability of the PCB board material box 53 during rotation.

[0182] In one embodiment, such as Figure 12 , Figure 18 As shown, the upper and lower PIN connection platform 600 also includes a switching mechanism 90, which is mounted on the material box bracket 61.

[0183] The PCB tray support 61 has a board receiving and dispensing station and two PCB exchange stations. The first position and the second position are both located at the board receiving and dispensing station. The board receiving and dispensing station is located between the two PCB exchange stations. The switching mechanism 90 can drive the PCB tray to move along the third direction c between the board receiving and dispensing station and one of the PCB exchange stations.

[0184] When the PCB board bin is located at the board receiving and discharging station and its opening faces the feeding mechanism 70, the feeding mechanism 70 can drive the PCB board into and out of the PCB board bin through the opening; when the PCB board bin is located at one of the bin exchange stations, the first conveying device 100 can drive the PCB board bin to leave or enter the bin support 61.

[0185] Wherein, the first direction a intersects with the third direction c, and the first direction a, the second direction b, and the third direction c are perpendicular to each other. In the PCB manufacturing field, in order to facilitate the docking of the PCB board material box with the drilling machine worktable 500, preferably, the rotating mechanism 80 drives the material box to switch from the first position to the second position, and the switching mechanism 90 drives the PCB board material box to move from the board receiving and discharging station to one of the material box exchange stations, and then the PCB board material box is transported by the first conveying device 100.

[0186] In this embodiment, the switching mechanism 90 can drive the PCB box to move along a third direction c between the board receiving / discharging station and the PCB box exchange station. When the PCB box at the board receiving / discharging station is full, the rotating mechanism 80 drives the PCB box to switch to the second position, and it can be quickly transferred to a PCB box exchange station. At the same time, empty PCB boxes can be moved from another PCB box exchange station to the board receiving / discharging station, ensuring that the feeding mechanism 70 can continuously feed materials. This avoids production stoppages caused by waiting for PCB box replacements and further improves the continuity and efficiency of material transportation.

[0187] In one embodiment, such as Figure 18 As shown, the shifting mechanism 90 includes an eleventh driving member 91, a linkage rod 92, and two support parts 93. The eleventh driving member 91 is mounted on the material box bracket 61, and the two support parts 93 are connected by the linkage rod 92. The support parts 93 are mounted on the material box bracket 61 and are used to support the material box.

[0188] The output end of the eleventh drive unit 91 is connected to one of the two support parts 93. Under the action of the linkage rod 92, the two support parts 93 can move simultaneously along the third direction c, so that the material box on each support part 93 can switch between the take-up and put-out plate station and the material box exchange station.

[0189] In one embodiment, such as Figure 18 As shown, the support part 93 includes two support seats 931, on which the PCB board box is mounted. A second positioning pin 9311 is provided on each support seat 931, which can engage with a second positioning member 533 at the bottom of the PCB board box. When the lifting drive 32 moves the lifting platform 33 upward, the first positioning pin 84 engages with the third positioning member 534, and simultaneously the second positioning pin 9311 separates from the second positioning member 533. At this time, the PCB board box leaves the support seat 931, and the rotating mechanism 80 rotates the box. A linear guide rail connects the support seat 931 and the box bracket 61. When the eleventh drive 91 moves the support part 93, the support seat 931 can move along the linear guide rail.

[0190] On the other hand, embodiments of the present invention provide a PCB board transportation method, applied to a PCB board conveying system, comprising: The second conveying device 200 is controlled to move to the transfer station 400. The first lifting mechanism 51 of the loading and unloading device drives the material box bracket 52 to move up and down, taking away multiple PCB board material boxes on the transfer station 400 and transferring multiple PCB board material boxes to the material box bracket 52.

[0191] The self-moving chassis of the second conveying device 200 drives the loading and unloading device to move to the drilling machine workbench 500. The conveying mechanism 20 of the loading and unloading device can drive the PCB board to move along the second direction, transferring the PCB board in each PCB board box to the corresponding processing station on the drilling machine workbench, thus realizing the automated operation of the loading process of the drilling machine workbench 500.

[0192] After the PCB board is processed, the conveying mechanism 20 of the loading and unloading device can drive the PCB board to move along the second direction and store the PCB board in the PCB board box. The second conveying device 200 is controlled to move to the transfer station 400. The first lifting mechanism 51 of the loading and unloading device drives the box bracket 52 to move up and down, transferring the PCB board box to the transfer station 400. The PCB board box is then transferred to the second box support 402 of the transfer station 400.

[0193] In one embodiment, after the PCB board is processed, storing the PCB board in the PCB board bin on the second conveying device 200 includes: After the PCB board is processed, the conveying mechanism 20 can receive the PCB board.

[0194] The two conveying components of the conveying mechanism 20 clamp the PCB board and drive the PCB board to move along the second direction, storing the PCB board in the temporary storage bin.

[0195] The first lifting mechanism 51 drives the PCB board bin to rise and fall, allowing the conveying mechanism 20 to dock with each temporary storage bin, storing the PCBs in the next temporary storage bin until the PCB board bin is full. By lifting the PCB board bin 53 driven by the first lifting mechanism 51, the height position of the conveying mechanism 20 and the height position of each temporary storage bin can be adjusted, ensuring accurate docking between the conveying mechanism 20 and each temporary storage bin, thereby storing the PCB boards in the PCB board bin.

[0196] In one embodiment, transferring the PCB board bin from the second conveyor 200 to the transfer station 400 via the loading and unloading device includes: The first lifting mechanism 51 lifts the PCB board material box; The second conveyor 200 moves so that the PCB board box is positioned above the transfer station 400; The first lifting mechanism 51 descends and places the PCB board box at the transfer station 400.

[0197] The base 10 is equipped with a material box bracket 52, on which PCB board material boxes are placed. A first lifting mechanism 51 can move the material box bracket 52 up and down, thereby moving the PCB board material box 53 up and down as well. When transferring to the transfer station 400, the first lifting mechanism 51 first moves the PCB board material box up and down to adjust the position of the material box bracket 52 so that the second material box support 402 can be inserted into the position below the PCB board material box. Then, the first lifting mechanism 51 drives the material box bracket 52 and the PCB board material box 53 to move downwards until the PCB board material box 53 lands on the second material box support 402. At the same time, the PCB board material box 53 detaches from the material box bracket 52, realizing the transfer of the PCB board material box.

[0198] In one embodiment, the PCB board conveying system further includes an upper and lower pin connection platform, a buffer station 300, and a first conveying device; the PCB board transportation method further includes: After the pins are attached, the PCB board is stored in the PCB board bin via the upper and lower pin connection platform 600, and then stored in the buffer station 300 or the transfer station 400 via the first conveying device 100. During the loading process, the second lifting mechanism 102 of the first conveying device 100 drives the support arm 103 to move up and down, so that the support arm 103 can remove the PCB board bin from the buffer station 300.

[0199] When the PCB board bin is located in the buffer station 300, the transport vehicle 101 of the first conveying device 100 moves, moving the PCB board bin from the buffer station 300 to the transfer station 400. The support arm 103 can extend into the PCB board bin. After the fifth positioning member 104 and the sixth positioning member 535 are inserted and cooperated, under the drive of the second lifting mechanism 102, the support arm 103 can support the PCB board bin, realizing the suspended transport of the PCB board bin, thereby placing the PCB board bins one by one in the transfer station 400. Each PCB board bin is placed on two adjacent second bin support members 402, and multiple PCB board bins are arranged side by side in the transfer station 400.

[0200] The second conveyor 200 drives the loading and unloading device to the transfer station 400, where it retrieves multiple PCB board boxes. The conveyor mechanism 20 moves the PCB boards in the boxes along a second direction, transferring each PCB board box to the corresponding processing station on the drilling machine worktable 500 for processing. After processing, each PCB board is stored in its corresponding PCB board box. The second conveyor 200 then transfers the multiple PCB board boxes to the transfer station 400.

[0201] Next, the transport vehicle 101 of the first conveying device 100 moves to the transfer station 400, and the first conveying device 100 removes the PCB board box on the transfer station 400 and transports the PCB board box to the buffer station 300 or the upper and lower PIN connection platform 600.

[0202] The PCB board bins can be moved one by one to the buffer station 300 or the upper and lower pin connection platform 600. Alternatively, multiple PCB board bins on the transfer station 400 can be stacked together for transport. The specific stacking process is as follows: With the support arm 103 able to extend into any PCB board bin on the transfer station 400, and the fifth positioning part 104 and the sixth positioning part 535 interlocked, the second lifting mechanism 102 drives one PCB board bin to be stacked on top of other PCB board bins. By repeating this operation, multiple PCB board bins on the transfer station 400 are stacked and then transported to the buffer station 300 or the upper and lower PIN docking platform 600, thus automating the unloading process of the drilling machine workbench 500.

[0203] While the upper and lower pin connection platform 600 is operating, PCB board boxes are transported to the buffer station 300 for storage. When a new PCB board box needs to be placed on the upper and lower pin connection platform 600 for transport, the first conveyor 100 transports the PCB board box from the buffer station 300 to the upper and lower pin connection platform 600, and the upper and lower pin connection platform 600 delivers the PCB board to the pinning machine 800 for pinning operation.

[0204] In this invention, the highly automated coordinated operation of the first conveying device 100, the loading and unloading device, and the second conveying device 200 ensures close and rapid connection between each link, resulting in good transfer efficiency. It also reduces the manual involvement in material handling, loading and unloading, and other processes, avoiding deviations that may occur during manual operation, ensuring the precision of the PCB board during processing, and helping to improve the processing quality and consistency of the product.

[0205] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
