Circuit boards can also be called printed circuit boards or printed circuit boards, with English names including (Printed Circuit Board) PCB and (Flexible Printed Circuit Board) FPC (also known as flexible circuit board). Flexible circuit boards are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. In today's era of rapid development in electronic technology, circuit boards are core components of electronic devices, and their quality and reliability directly affect the performance of electronic devices. In the production, debugging, and repair of circuit boards, various auxiliary tools are needed to ensure the accuracy and efficiency of operations. In the field of circuit board repair, fixtures are a commonly used auxiliary tool.

[0003] Existing fixtures require operators to manually tighten multiple screws back and forth with tools to complete the clamping action when clamping and positioning circuit boards. This operation is cumbersome, which not only wastes the time of maintenance personnel but also reduces maintenance efficiency. Therefore, we urgently need to provide an auxiliary fixture for circuit board maintenance.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue that operators need to manually tighten multiple screws with tools to complete the clamping action, which is cumbersome, wastes maintenance personnel's time, and reduces maintenance efficiency, this application provides an auxiliary fixture for circuit board repair.

[0006] The circuit board repair auxiliary fixture provided in this application adopts the following technical solution:

[0007] A circuit board repair auxiliary fixture includes a clamping platform. Two fixed clamping plates are fixedly connected to both sides of the upper end of the clamping platform. Two slide rails are provided at the upper end of the clamping platform. Each slide rail has a movable clamping plate at its upper end. A slider is fixedly connected to the bottom of each movable clamping plate. The slider is slidably connected to the inside of the slide rail. The bottom of each slider has a cut surface. A one-way screw is threaded to the middle of the front end of the clamping platform. A handwheel is fixedly connected to the outer end of the one-way screw. A conical block is rotatably connected to the end of the one-way screw away from the handwheel. The two sides of the inner surface of the conical block correspond to the cut surfaces at the bottom of the two sliders, respectively. A limit groove is provided at the upper end of the inner surface of the clamping platform. A connecting block is fixedly connected to the upper end of the conical block. The connecting block is slidably connected to the inside of the groove.

[0008] Preferably, each of the two slide rails has a guide rod fixedly connected inside, and the slider has a through hole in the middle and is slidably connected to the surfaces of the two guide rods respectively.

[0009] Preferably, a return spring is fixedly connected to the side of each of the two sliders, and the other end of the two return springs is fixedly connected to the side of the slide rail. The return springs are respectively sleeved on the outside of the guide rod.

[0010] Preferably, the four corners of the bottom of the clamping platform are fixedly connected with anti-slip feet, and both sides of the fixed clamping plate and the movable clamping plate are threaded with adjusting screws.

[0011] Preferably, a handle is fixedly provided on the outer side of each of the plurality of adjusting screws, and a clamping block is fixedly connected to the side of each adjusting screw away from the handle.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] This invention achieves rapid clamping and positioning of circuit boards through the coordinated structure of a one-way screw, a conical block, a slider, and a movable clamping plate. Maintenance personnel only need to turn the handwheel to rotate the one-way screw, causing the conical block to push the slider along the slide rail. This allows the movable clamping plate to quickly approach the fixed clamping plate and clamp the circuit board. When it is necessary to remove the circuit board, the one-way screw is rotated in the opposite direction, causing the conical block to move towards the front end of the clamping platform. At this time, under the action of the return spring, the two clamping plates and the slider automatically reset. Compared with existing clamps that require the cumbersome operation of manually tightening multiple screws, this invention greatly improves clamping efficiency and is simpler and more convenient to operate.

Detailed Implementation

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] This application discloses an auxiliary fixture for circuit board repair, referring to... Figures 1-4 The device includes a clamping platform 1, with two fixed clamping plates 3 fixedly connected to both sides of its upper end. Two slide rails 4 are provided at the upper end of the clamping platform 1, and each slide rail 4 has a movable clamping plate 6 at its upper end. A slider 7 is fixedly connected to the bottom of each movable clamping plate 6, and the slider 7 is slidably connected inside the slide rail 4. The bottom of each slider 7 has a cut surface 9, which is designed to cooperate with a conical block 12, improving the efficiency of force transmission. When clamping a circuit board, the conical block 12 can more effectively push the slider 7, causing the movable clamping plate 6 to quickly approach the fixed clamping plate 3, achieving rapid clamping and reducing energy loss. A one-way screw 10 is threadedly connected to the center of the front end of the clamping platform 1, and a handwheel 11 is fixedly connected to the outer end of the one-way screw 10. A conical block 12 is rotatably connected to the end of the one-way screw 10 away from the handwheel 11. The two sides of the inner surface of the conical block 12 correspond to the cut surfaces 9 at the bottom of the two sliders 7. Rotating the handwheel 11 will drive the one-way screw 10 to rotate, causing the conical block 12 to push the slider 7 along the slide rail 4, thereby allowing the movable clamping plate 6 to quickly approach the fixed clamping plate 3 and clamp the circuit board. A limiting groove 13 is provided at the upper end of the inner surface of the clamping base 1. A connecting block 14 is fixedly connected to the upper end of the conical block 12. The connecting block 14 is slidably connected inside the groove. The limiting groove 13 provides a track and directional restriction for the connecting block 14, ensuring that the conical block 12 can only move in the predetermined direction, thereby ensuring the accuracy and stability of the conical block 12 pushing the slider 7.

[0021] Reference Figures 1-4Guide rods 5 are fixedly connected inside both slide rails 4. A through hole is opened in the middle of the slider 7, which is slidably connected to the surfaces of the two guide rods 5. Return springs 8 are fixedly connected to the sides of both sliders 7, and the other ends of the two return springs 8 are fixedly connected to the sides of the slide rails 4. The return springs 8 are respectively sleeved on the outside of the guide rods 5. When the circuit board needs to be disassembled, the one-way screw 10 is rotated in the reverse direction, causing the conical block 12 to move towards the front end of the clamping platform 1. At this time, under the action of the return springs 8, the two clamping plates and sliders 7 automatically reset, facilitating quick and easy disassembly of the circuit board and improving the overall efficiency of maintenance operations. The bottom of the clamping platform 1 is fixedly connected to four anti-slip feet 2 at each of the four corners. The anti-slip feet 2 provide stable support for the fixture and ensure that the fixture will not move during maintenance. The fixed clamping plate 3 and the movable clamping plate 6 are both threadedly connected to adjusting screws 15. The outer side of the multiple adjusting screws 15 is fixedly provided with a handle 16. The side of the adjusting screw 15 away from the handle 16 is fixedly connected to a clamping block 17. The position of the two clamping blocks 17 can be adjusted by adjusting the adjusting screws 15 as needed to clamp and fix the upper and lower sides of the circuit board. This can facilitate the clamping and positioning of circuit boards of different widths and enhance the applicability of the device.

[0022] The implementation principle of the circuit board repair auxiliary fixture in this application embodiment is as follows: In specific use, the circuit board is first placed between the fixed clamping plate 3 and the movable clamping plate 6 of the clamping platform 1. Then, the handwheel 11 is rotated, which drives the one-way screw 10 to rotate. Since the one-way screw 10 is threadedly connected to the clamping platform 1, the one-way screw 10 will move into the clamping platform 1 while rotating. The conical block 12, which is rotatably connected to the other end of the one-way screw 10, also moves accordingly. The two sides of the inner surface of the conical block 12 are aligned with the tangent surface 9 at the bottom of the slider 7. Correspondingly, as the conical block 12 moves, it pushes the slider 7 to move to both sides along the slide rail 4. The through hole in the middle of the slider 7 is slidably connected to the guide rod 5 inside the slide rail 4, ensuring the smooth movement of the slider 7. At the same time, the return spring 8 on the side of the slider 7 is compressed, providing a certain buffer force for the movable clamping plate 6. When the movable clamping plate 6 moves to the appropriate position and clamps the circuit board together with the fixed clamping plate 3, the positions of the two clamping blocks 17 are adjusted by adjusting the screw 15 as needed to clamp and fix the upper and lower sides of the circuit board.
