Description

Technical Field

[0001] The present application relates to the field of PCB board production equipment, and in particular to a PCB board insertion frame. Background Art

[0002] In the production process of PCB boards, from raw material input to finished product output, it will go through multiple processing steps, such as printing, exposure, etching, drilling, plating, welding, etc. PCB boards need to be stored during this process. The PCB boards to be processed usually need to be separated and inserted in special board frames. These board frames are designed with multiple slots, each of which can store a single piece to maintain the spacing between boards, prevent PCB boards from contacting each other, and avoid scratches on adjacent PCB boards.

[0003] A clamping mechanism is usually provided inside the insertion frame, which is used to clamp the PCB board, and a robot is usually provided on the top of the insertion frame, which is used to place the PCB board vertically in the clamping mechanism. In the automated PCB board production process, the coordinated work of the clamping mechanism and the robot is crucial, but since the two are driven separately, their movement synchronization cannot be guaranteed. When the clamping mechanism is started in advance without waiting for the robot to completely place the PCB board, the PCB board will be fixed before reaching the predetermined position, resulting in insufficient insertion depth of the PCB board. Due to the insufficient insertion depth, the position of the PCB board in the placement frame will result in insufficient support, making the PCB board easy to fall off or move during subsequent handling or processing, resulting in reduced accuracy of processing steps such as drilling and welding, affecting the final product. On the contrary, if the clamping mechanism is activated after the manipulator has placed the PCB board beyond the predetermined position, the PCB board will be inserted too deeply, causing the bottom components of the PCB board to collide with the bottom of the placement frame. Since the components are usually fragile, this collision will cause damage to the components. In addition to component damage, the solder joints, wires or circuit paths on the PCB board will also be physically damaged due to the too-deep insertion of the PCB board, affecting the functionality of the circuit. Due to component damage or PCB board damage, the production cost of the PCB board will increase, and the production schedule may also be delayed. In the prior art, PCB boards are stacked, resulting in relative movement between adjacent PCB boards when the insertion frame is moved, resulting in friction between adjacent plates, causing damage to components on the PCB board. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a PCB board insert frame, which can solve the technical problem that the stacked PCB boards will cause friction.

[0005] According to the first aspect of the present application, the PCB board insertion frame comprises: a frame; a clamping part, which is provided with a plurality of parts and is respectively arranged inside the frame for clamping the PCB board, the clamping part comprises a first positioning plate and a second positioning plate, the first positioning plate is arranged inside the frame, the second positioning plate is movably connected to the inside of the frame, and the first positioning plate and the second positioning plate are separated to form a first clamping interval; a transmission part, which is provided with a plurality of parts and is respectively arranged outside the frame, the transmission part comprises a mounting seat, a vertical rod, a reset spring and a contact end, the mounting seat is arranged outside the frame, the vertical rod is slidably connected to the inside of the mounting seat, the A return spring is installed on the top of the vertical rod, and the return spring is connected to the mounting seat.

[0006] The PCB board insertion frame according to the embodiment of the present application has at least the following beneficial effects: when the external mechanical arm places the PCB board in the first clamping interval, the mechanical arm will contact with the contact end at the top of the vertical rod and push the vertical rod to move downward. When the vertical rod slides in the mounting seat, the vertical rod drives the first connecting rod to rotate. At this time, the reset spring will shrink under the push of the vertical rod, and the first connecting rod drives the second connecting rod to rotate, so that the other end of the second connecting rod drives the second positioning plate to move, and the second positioning plate gradually moves away from the first positioning plate, so that the space of the first clamping interval becomes larger. When the PCB board is correctly placed in the first clamping interval, , the external mechanical arm disengages from the contact end with the top of the vertical rod and no longer applies downward force to the vertical rod. The reset spring stretches, thereby driving the vertical rod to move upward, so that the second positioning plate gradually approaches the first positioning plate, and the space of the first clamping interval is reduced, and finally the PCB board located in the interval is clamped, so that the mechanical arm and the second positioning plate are transmitted synchronously, ensuring the accurate insertion depth of the PCB. The elasticity of the reset spring also ensures the uniform distribution of the clamping force, avoiding the PCB board from falling off or moving during transportation or processing, and also preventing the risk of the PCB board being inserted too deeply and causing damage to the bottom components.

[0038] Reference Figures 1 to 8 The PCB board insertion frame of the present application includes: a frame body 100, a clamping part 200, a transmission part 300 and a linkage part 400.

[0039] The clamping parts 200 are provided with a plurality of parts, which are respectively arranged inside the frame 100 at intervals, and are used to clamp the PCB board 110. The clamping parts 200 include a first positioning plate 210 and a second positioning plate 220. The first positioning plate 210 is arranged inside the frame 100, and the second positioning plate 220 is movably connected to the inside of the frame 100. The first positioning plate 210 and the second positioning plate 220 are separated to form a first clamping interval 250.

[0040] The transmission part 300 is provided with a plurality of parts, which are respectively arranged outside the frame 100. The transmission part 300 includes a mounting seat 310, a vertical rod 311, a return spring 313 and a contact end 316. The mounting seat 310 is arranged outside the frame 100. The vertical rod 311 is slidably connected with the inside of the mounting seat 310. The return spring 313 is installed on the top of the vertical rod 311. The return spring 313 is connected to the mounting seat 310. The contact end 316 is arranged on the top of the vertical rod 311, and the contact end 316 is located above the return spring 313.

[0041] The linkage part 400 is provided with multiple, which are movably connected with multiple clamping parts 200 and multiple transmission parts 300 respectively. The linkage part 400 includes a first connecting rod 410 and a second connecting rod 450. One end of the first connecting rod 410 is movably connected to one side of the vertical rod 311, one end of the second connecting rod 450 is rotatably connected to the mounting seat 310, one side of the second connecting rod 450 is movably connected to the other end of the first connecting rod 410, and the other end of the second connecting rod 450 is movably connected to the second positioning plate 220, so that the vertical rod 311 drives the second positioning plate 220 to open and close the first clamping interval 250.

[0042] It should be noted that, by having a plurality of clamping parts 200 spaced apart inside the frame 100, when the clamping parts 200 clamp the PCB board 110, adjacent PCB boards 110 will not come into contact with each other. Therefore, when the frame 100 is moved, adjacent PCB boards 110 will not rub against each other, thereby avoiding direct contact between the PCB boards 110 and reducing the risks of surface damage, scratches and component damage.

[0043] It can be understood that when the external mechanical arm places the PCB board 110 in the first clamping interval 250, the mechanical arm will contact the contact end 316 at the top of the vertical rod 311 and push the vertical rod 311 to move downward. When the vertical rod 311 slides in the mounting seat 310, the vertical rod 311 drives the first connecting rod 410 to rotate. At this time, the return spring 313 will shrink under the push of the vertical rod 311, and the first connecting rod 410 drives the second connecting rod 450 to rotate, so that the other end of the second connecting rod 450 drives the second positioning plate 220 to move, and the second positioning plate 220 gradually moves away from the first positioning plate 210, so that the space of the first clamping interval 250 becomes larger. When the PCB board 110 is correctly placed in the first clamping interval 250, After that, the external mechanical arm disengages from the contact end 316 at the top of the vertical rod 311 and no longer applies downward force to the vertical rod 311. The reset spring 313 stretches, thereby driving the vertical rod 311 to move upward, so that the second positioning plate 220 gradually approaches the first positioning plate 210, and the space of the first clamping interval 250 is reduced, and finally the PCB board 110 located in the interval is clamped, so that the mechanical arm and the second positioning plate 220 are driven synchronously, ensuring the accurate insertion depth of the PCB. The elasticity of the reset spring 313 also ensures the uniform distribution of the clamping force, avoiding the PCB board 110 from falling off or moving during transportation or processing, and also preventing the risk of the PCB board 110 being inserted too deeply and causing damage to the bottom components.

[0044] In addition, a protrusion is provided at the bottom of the external manipulator, and the protrusion corresponds to the contact end 316. As the manipulator moves downward, the protrusion at the bottom of the manipulator gradually approaches the contact end 316 of the vertical rod 311. When the two are in contact, the protrusion and the contact end 316 collide with each other. After the collision occurs, the manipulator continues to apply force downward, and this force is transmitted to the contact end 316 through the protrusion, and then transmitted to the vertical rod 311, causing the vertical rod 311 to start moving downward, which helps to ensure that the transmission of force by the manipulator is uniform and reliable, and avoids force loss or directional deviation due to poor contact.

[0045] In a specific implementation, the number of the first connecting rod 410 and the second connecting rod 450 can be two groups, one group is located above the vertical rod 311, and the other group is located below the vertical rod 311, so as to disperse the load when the vertical rod 311 moves and ensure the consistency and stability when the vertical rod 311 drives the second positioning plate 220 to move.

[0046] In addition, the first link 410 and the second link 450 form a herringbone shape, and the herringbone structure can distribute load and stress more evenly, thereby reducing component damage caused by local stress concentration.

[0047] Reference Figures 3 to 6The linkage part 400 includes a first limit plate 312 and a second limit plate 314. The first limit plate 312 is arranged at the top of the vertical rod 311, and the contact end 316 is arranged at the top of the first limit plate 312. The second limit plate 314 is arranged at the top of the mounting seat 310. The first limit plate 312 and the second limit plate 314 are separated to form a limit interval 315. The return spring 313 is located inside the limit interval 315, so that one end of the return spring 313 contacts the first limit plate 312, and the other end of the return spring 313 contacts the second limit plate 314.

[0048] The reset spring 313 then starts to work, and the reset spring 313 pushes the vertical rod 311 to move upward, and at the same time drives the first connecting rod 410 and the second connecting rod 450 connected thereto to return to their initial positions, so that the first positioning plate 210 and the second positioning plate 220 clamp the PCB board 110.

[0049] In addition, the first limiting plate 312 provides a support point for one end of the return spring 313, and the second limiting plate 314 provides a fixed support point for the other end of the return spring 313, ensuring that the return spring 313 remains in the correct position during compression and extension.

[0050] Reference Figures 3 to 5 The linkage part 400 includes an adjusting rod 420, a rotating column 430 and a limiting nut 421. A first adjusting groove 320 is opened inside the vertical rod 311. The rotating column 430 is arranged at one end of the adjusting rod 420. A first rotating groove 440 is opened at one end of the first connecting rod 410. The rotating column 430 rotates with the first rotating groove 440. One end of the adjusting rod 420 slides with the first adjusting groove 320, so that one end of the adjusting rod 420 passes through the first adjusting groove 320. The limiting nut 421 is threadedly engaged with the protruding end of the adjusting rod 420, so that the limiting nut 421 conflicts with the vertical rod 311.

[0051] It can be understood that when the adjustment rod 420 slides up and down in the groove, the relative height of the vertical rod 311 can be changed, so that the initial distance between the second positioning plate 220 and the first positioning plate 210 changes. If the vertical rod 311 rises, the second positioning plate 220 will be close to the first positioning plate 210, thereby reducing the space of the first clamping interval 250; on the contrary, if the vertical rod 311 drops, the second positioning plate 220 will be away from the first positioning plate 210, increasing the space of the first clamping interval 250, thereby facilitating the adjustment of the space of the first clamping interval 250 according to the thickness of the PCB board 110.

[0052] In addition, the limiting nut 421 is threadedly engaged with the protruding end of the adjusting rod 420 . By rotating the limiting nut 421 , the sliding range of the adjusting rod 420 can be limited, thereby fixing the height position of the vertical rod 311 .

[0053] Reference Fig. 9 The transmission part 300 includes an adjustment base frame 360, a first adjustment nut 330 and a second adjustment nut 340. The adjustment base frame 360 ​​is arranged outside the frame 100, and the adjustment base frame 360 ​​is located below the mounting seat 310. A second adjustment groove 361 is opened inside the adjustment base frame 360. The bottom of the vertical rod 311 is slidably matched with the second adjustment groove 361. The first adjustment nut 330 and the second adjustment nut 340 are threadedly matched with the bottom of the vertical rod 311. The first adjustment nut 330 and the second adjustment nut 340 are separated to form a second clamping interval 350, and the adjustment base frame 360 ​​is located in the second clamping interval 350.

[0054] It is understandable that when the first adjusting nut 330 and the second adjusting nut 340 move to a certain extent, they are close to the upper and lower sides of the adjusting base 360, thereby limiting the further movement of the vertical rod 311, achieving a limiting effect, and realizing fine adjustment of the height of the vertical rod 311.

[0055] Reference Figure 5 The linkage part 400 includes a first fixed shaft 460, a first fixed socket 462 and two first fixed strips 463. The first fixed shaft 460 is arranged on one side of the second connecting rod 450. The other end of the first connecting rod 410 is provided with a second rotation groove 464. The first fixed shaft 460 and the second rotation groove 464 are rotatably matched. One end of the first fixed shaft 460 passes through the second rotation groove 464. A first fixing hole 461 is provided inside the passing end of the first fixed shaft 460. The two first fixed strips 463 are elastic. The two first fixed strips 463 are arranged on one side of the first fixed socket 462 so that the two first fixed strips 463 are clamped with the first fixing holes 461.

[0056] It is understandable that since the first connecting rod 410 and the second connecting rod 450 are transmission parts, they are prone to damage or wear under long-term operation, and therefore need to be repaired or replaced; when the first connecting rod 410 needs to be disassembled, first loosen the first fixing strip 463 to release it from the first fixing hole 461, and let the first fixed shaft 460 disengage from the second rotating groove 464 of the first connecting rod 410, and cooperate with the rotation limit nut 421 of the adjusting rod 420 to screw out, thereby facilitating the replacement of the first connecting rod 410.

[0057] Reference Figure 6 to Figure 7 The clamping portion 200 includes a hidden side plate 240 , and the hidden side plate 240 is disposed on one side of the second positioning plate 220 , so that the hidden side plate 240 faces the second connecting rod 450 .

[0058] It is understandable that the direction of the hidden side plate 240 toward the second connecting rod 450 may help reduce the interference of external components and improve the working stability of the second connecting rod 450 and the first connecting rod 410.

[0059] Reference Figures 6 to 10 The linkage part 400 includes a second fixed shaft 480, a second fixed socket 490 and two second fixed strips 491. The second fixed shaft 480 is arranged at the other end of the second connecting rod 450. A third rotation groove 470 is opened inside the hidden side plate 240. The second fixed shaft 480 rotates with the third rotation groove 470. One end of the second fixed shaft 480 passes through the third rotation groove 470. A second fixing hole 492 is opened inside the passing end of the second fixed shaft 480. The two second fixing strips 491 are elastic. The two second fixing strips 491 are arranged on one side of the second fixed socket 490 so that the two second fixing strips 491 are clamped with the second fixing holes 492.

[0060] It can be understood that when the second connecting rod 450 needs to be disassembled, the second fixing strip 491 is first loosened to release it from the second fixing hole 492, allowing the second fixing shaft 480 to disengage from the third rotation groove 470 of the second connecting rod 450, and allowing the second fixing shaft 480 to disengage from the third rotation groove 470 of the hidden side panel 240, and the first fixing strip 463 is loosened to release it from the first fixing hole 461, allowing the first fixing shaft 460 to disengage from the second rotation groove 464 of the first connecting rod 410, thereby facilitating the replacement of the second connecting rod 450.

[0061] Reference Figures 4 to 6 The clamping portion 200 includes a first guide plate 211 and a second guide plate 221. The first guide plate 211 is arranged on the top of the first positioning plate 210, and the first guide plate 211 is inclined toward the first clamping interval 250. The second guide plate 221 is arranged on the top of the second positioning plate 220, and the second guide plate 221 is inclined toward the first clamping interval 250.

[0062] It can be understood that the inclined direction of the first guide plate 211 and the second guide plate 221 helps to ensure that the PCB board 110 can smoothly enter the clamping interval, so that the PCB board 110 remains in the correct position, and the inclined design can reduce the friction and wear between the PCB board 110 and the first guide plate 211 and the second guide plate 221, thereby further protecting the PCB board 110.

[0063] Reference Figure 7 The clamping part 200 includes a clamping bolt 231 and a clamping end 232. An adjustment hole 230 is opened inside the second positioning plate 220. The clamping bolt 231 is threadedly matched with the adjustment hole 230. The clamping end 232 is arranged at one end of the clamping bolt 231. The clamping end 232 passes through the adjustment hole 230 so that the clamping end 232 is located in the first clamping interval 250.

[0064] It is understandable that the clamping bolt 231 is threadedly matched with the adjustment hole 230 so that the clamping end 232 can be fine-tuned within the first clamping interval 250 to ensure that the PCB board 110 or other workpiece can be accurately clamped, further improving the stability of the PCB board 110 clamping.

[0065] It should be noted that, in order to prevent the clamping end 232 from damaging the PCB board 110 , the position of the clamping end 232 is preferably designed to be at a position on the PCB board 110 where there are no components.

[0066] Reference Figure 1 to Figure 2 A placement base frame 120 is provided inside the frame 100 , and the placement base frame 120 is located below the first clamping interval 250 . A plurality of placement grooves 121 are provided on the top of the placement base frame 120 , and the placement grooves 121 are used to place the bottom of the PCB board 110 .
