Description

Technical Field

[0001] This utility model relates to the field of printed circuit board processing, and in particular to a mobile storage carrier after drilling large-size PCBs. Background Technology

[0002] Large-size PCB post-drilling mobile storage carriers are specialized devices for the safe transport and storage of drilled PCBs. They typically feature anti-static, scratch-resistant, and adjustable structures. These carriers are often made of stainless steel frames, conductive wheels, or anti-static materials to effectively release static electricity and prevent damage to the boards. Some designs are also heat-resistant to meet subsequent process requirements. They are widely used for inter-process transport and temporary storage in electronics factories, improving handling efficiency and product yield.

[0003] When large-size PCBs are stored in traditional carriers, relying solely on the carrier's frame or simple placement slots for restraint, they are prone to lateral or longitudinal displacement during transport due to bumps. During this displacement, the edges of the PCBs may collide with the carrier frame, or multiple PCBs may rub against each other. Furthermore, the presence of holes in the drilled PCBs weakens their overall impact resistance and edge strength, making them highly susceptible to edge chipping, hole deformation, or surface scratches, directly impacting product yield. Additionally, manually adjusting some brackets in traditional carriers can lead to asynchronous adjustments, causing the PCB to tilt and concentrate stress on one edge. During transport, the board may slide along this tilt, potentially causing edge chipping and long-term uneven stress leading to hidden deformation, affecting subsequent processing accuracy. Therefore, a new type of large-size PCB drilling and subsequent moving storage carrier is proposed to address these issues. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a large-size PCB drilling and subsequent mobile storage carrier, including a bracket, a ground chain fixedly connected to the bottom outer wall of the bracket, an outer frame fixedly connected to the top outer wall of the bracket, a fixing mechanism provided on the inner wall of the outer frame, and an adjustment mechanism provided on the inner wall of the outer frame.

A crank is fixedly connected to the outer wall of the first threaded rod. A sliding frame is rotatably connected to the outer wall of the bottom end of the first threaded rod.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the crank handle of the rotating fixing mechanism drives the first threaded rod to rotate on the inner wall of the outer frame. When the first threaded rod rotates, it drives the sliding frame to slide up and down along the second sliding groove on the inner wall of the outer frame. When the sliding frame moves, the first sliding groove on the inner wall drives the slider to slide. The slider is linked to the connecting rod, and the connecting rod slides along the inner wall of the bracket, driving the connecting block to move in the third sliding groove. The connecting block then pushes the clamping block. Multiple sets of clamping blocks approach and clamp the PCB board simultaneously, completing the fixation. This improves the problem in the prior art where the traditional carrier has no reliable limit, causing the PCB board to be easily displaced and damaged during movement.

[0018] 2. In this utility model, the threaded block connected to the outer wall of the second threaded rod of the rotating adjustment mechanism moves under the action of the thread. The threaded block drives the third bracket to move, and the second hinge sleeve on the side wall of the third bracket moves accordingly. The second hinge sleeve drives the second hinge plate to rotate, and the second hinge plate rotates around the first hinge sleeve in conjunction with the first hinge plate. The first hinge plate pushes the two sets of second brackets to move synchronously, and finally realizes the adjustment of the distance between the first bracket, the second bracket, and the third bracket, which can be adapted to PCBs of different sizes. This improves the problem of tilting caused by the lack of synchronization when manually adjusting the brackets in the traditional carrier in the prior art. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 As shown, one embodiment of this utility model provides a mobile storage carrier for large-size PCBs after drilling, including a bracket 1. A ground chain 4 is fixedly connected to the bottom outer wall of the bracket 1, and the bottom end of the ground chain 4 is in contact with the ground. The ground chain 4 can eliminate static electricity generated during equipment operation and protect the equipment and personnel safety. An outer frame 5 is fixedly connected to the top outer wall of the bracket 1. A second sliding groove 29 is opened on the inner wall of the outer frame 5. The outer frame 5 provides an installation position for threaded rods, etc. A fixing mechanism 2 is provided on the inner wall of the outer frame 5. The fixing mechanism 2 can fix the PCB board and restrict the movement of the PCB board to prevent displacement through components such as clamping blocks 27. An adjustment mechanism 3 is provided on the inner wall of the outer frame 5. The adjustment mechanism 3 adjusts the bracket spacing to adapt to PCB boards of different sizes and improves the versatility of the carrier.

[0029] Reference Figures 2-4As shown, the fixing mechanism 2 includes a first bracket 24. The inner walls of the first bracket 24, second bracket 25, and third bracket 26 are provided with third sliding grooves 28. The first bracket 24 carries the PCB board and provides a sliding track to support the connecting rod 212 and connecting block 211. The first bracket 24 is fixedly connected to the outer wall of the bracket 1. Connecting rods 212 are slidably connected to the inner wall of the first bracket 24. Four sets of connecting rods 212 are provided, and the four sets of connecting rods 212 are respectively slidably connected to the inner walls of the second bracket 25 and the third bracket 26. The connecting rods 212 connect the slider 210 and the connecting block 211 to transmit the movement of the sliding frame 23. The force drives the clamping block 27 to move. The outer wall of the connecting rod 212 is fixedly connected to the connecting block 211. The connecting block 211 is slidably connected in the third slide groove 28. The connecting block 211 connects the connecting rod 212 and the clamping block 27, and transmits the power of the connecting rod 212 to the clamping block 27 to achieve clamping. The outer wall of the connecting block 211 is fixedly connected to the clamping block 27. Several sets of clamping blocks 27 are provided, and several sets of clamping blocks 27 are slidably connected in the slots of the first bracket 24, the second bracket 25, and the third bracket 26. The inner wall of the clamping block 27 is pasted with an elastic buffer layer that directly contacts the PCB board and clamps the PCB from the side to prevent the PCB from shaking when moving and storing.

[0030] Reference Figures 3-5 As shown, a slider 210 is fixedly connected to the top outer wall of the connecting rod 212. The slider 210 is slidably connected to the inner wall of the first slide groove 213. The slider 210 is slidably connected to the sliding frame 23 and the connecting rod 212 within the first slide groove 213 to transmit the moving force. A second bracket 25 is slidably connected to the outer wall of the bracket 1. Two sets of second brackets 25 are provided, and the two sets of second brackets 25 are arranged in a straight line on the outer wall of the bracket 1. The second brackets 25 assist the first bracket 24 in supporting the PCB, increasing the support points and improving the stability of the PCB placement. A third bracket 26 is slidably connected to the outer wall of the bracket 1. The third bracket 26 cooperates with the adjustment mechanism 3 to adjust the position to adapt to different lengths. The PCB board has a first threaded rod 22 threaded to the inner wall of the outer frame 5. When the first threaded rod 22 transmits power to the crank handle 21 to rotate, it drives the sliding frame 23 to move up and down to adjust the clamping block 27. The crank handle 21 is fixedly connected to the outer wall of the first threaded rod 22. The crank handle 21 is held and rotated by the operator to drive the first threaded rod 22 to rotate and adjust the sliding frame 23. The bottom outer wall of the first threaded rod 22 is rotatably connected to the sliding frame 23. The inner wall of the sliding frame 23 has a first sliding groove 213. The sliding frame 23 is slidably connected in the second sliding groove 29. The sliding frame 23 moves to drive the slider 210, thereby controlling the connecting rod 212 and the clamping block 27 to fix the PCB.

[0031] Reference Figure 3 and Figure 6As shown, the adjusting mechanism 3 includes a second threaded rod 31. When the second threaded rod 31 rotates, it drives the threaded block 32 to move, providing power for adjusting the bracket spacing. The second threaded rod 31 is rotatably connected to the inner wall of the outer frame 5. The outer wall of the second threaded rod 31 is threadedly connected to the threaded block 32. The threaded block 32 is fixedly connected to the top outer wall of the third bracket 26. The threaded block 32 connects the second threaded rod 31 and the third bracket 26, converting the rotational force of the threaded rod into the moving force of the bracket. The side wall of the first bracket 24 is fixedly connected to a first hinge sleeve 33. The first hinge sleeve 33 connects the first bracket 24 and the first hinge plate 34, providing a rotation fulcrum for the hinge plate. The inner wall of the hinge sleeve 33 is hinged with a first hinge plate 34. The first hinge plate 34 transmits the force between the first hinge sleeve 33 and the second hinge plate 35 to assist in adjusting the bracket. The outer wall of the first hinge plate 34 is hinged with a second hinge plate 35. The second hinge plate 35 connects the first hinge plate 34 and the second hinge sleeve 36 to adjust the position of the bracket. The outer wall of the second hinge plate 35 is hinged with a second hinge sleeve 36. There are three sets of second hinge sleeves 36, and one set of second hinge sleeves 36 is set on the side wall of each of the two sets of second brackets 25 and the third bracket 26. The second hinge sleeves 36 connect the second hinge plate 35 and the bracket so that the bracket can be adjusted by rotating with the hinge plate.

[0032] In use, rotating the handle 21 of the fixing mechanism 2 causes the first threaded rod 22 to rotate on the inner wall of the outer frame 5. When the first threaded rod 22 rotates, it causes the sliding frame 23 to slide up and down along the second sliding groove 29 on the inner wall of the outer frame 5. When the sliding frame 23 moves, the first sliding groove 213 on the inner wall causes the slider 210 to slide. The slider 210 is linked to the connecting rod 212. The connecting rod 212 slides along the inner walls of the first bracket 24, the second bracket 25, and the third bracket 26, causing the connecting block 211 to move in the third sliding groove 28. The connecting block 211 then pushes the clamping block 27. Multiple sets of clamping blocks 27 simultaneously approach and clamp the PCB board, completing the fixing.

[0033] When the adjustment mechanism 3 is working, rotating the second threaded rod 31 of the adjustment mechanism 3 causes the threaded block 32 connected to its outer wall to move under the action of the thread. The threaded block 32 drives the third bracket 26 to move, and the second hinge sleeve 36 on the side wall of the third bracket 26 moves accordingly. The second hinge sleeve 36 drives the second hinge plate 35 to rotate, and the second hinge plate 35, in conjunction with the first hinge plate 34, rotates around the first hinge sleeve 33. The first hinge plate 34 pushes the two sets of second brackets 25 to move synchronously, ultimately realizing the adjustment of the distance between the first bracket 24, the second bracket 25, and the third bracket 26 to adapt to PCBs of different sizes.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
