Description

Technical Field

[0001] This utility model relates to the field of printed circuit board processing technology, specifically a clamping device for printed circuit board processing with a flipping structure. Background Technology

[0002] Clamping devices for printed circuit board (PCB) processing are key equipment in the electronics manufacturing industry used to fix, position, and manipulate PCB boards. Their core function is to achieve stable clamping of PCB boards through mechanical structures, ensuring accuracy and safety during the processing.

[0003] Currently, there are many types of clamping devices for printed circuit board (PCB) processing. For example, Chinese Patent No. CN202322260437.6 describes a clamping device for PCB processing. This patent includes a base, with symmetrically distributed vertical plates slidably engaged at the top of the base. A telescopic rod is movably threaded through one side of one vertical plate, and a rotating rod is rotatably connected to one side of the other vertical plate. Fixed frames are fixedly connected to opposite sides of both the telescopic rod and the rotating rod. A sliding rod is movably threaded through the top of the fixed frame, and a clamping plate is fixedly connected to the bottom of the sliding rod. A space is provided between the top surface of the inner wall of the fixed frame and the top of the clamping plate. There is a compression spring, which is movably sleeved on the outside of the slide rod. A mounting frame is fixedly connected to one side of the vertical plate, and a worm gear is rotatably connected to one side of the inner wall of the mounting frame. By rotating the adjustment knob, the worm gear is driven to rotate. The worm gear and worm wheel are meshed and connected, which simultaneously drives the worm wheel and the rotating rod to rotate, adjusting the vertical angle of the circuit board, which facilitates the soldering operation and further improves the soldering efficiency of the circuit board. However, in actual use, because the device needs to use the clamped circuit board as a conductor to make the angle of the two fixed frames flip and adjust, this method can easily lead to damage to the circuit board.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-4 In this embodiment, a clamping device for processing printed circuit boards with a flipping structure includes a machine table 1. A slot 101 is provided on the machine table 1. A spacing adjustment component 2 is provided inside the slot 101. Two movable plates 3 are provided on the spacing adjustment component 2. A flipping clamping mechanism 4 is provided between the two movable plates 3.

[0023] The flipping clamping mechanism 4 includes a rotating shaft 401 and a transmission rod 402. The rotating shaft 401 is fixedly mounted on both movable plates 3. A mounting bracket 403 is fixedly mounted on the right side of the right movable plate 3. A reciprocating servo motor 404 is fixedly mounted on the mounting bracket 403. The output end of the reciprocating servo motor 404 is fixedly connected to the right rotating shaft 401 via the transmission rod 402. A clamping seat 405 is fixedly connected to the adjacent ends of both rotating shafts 401. Connecting blocks 410 are fixedly connected to the front and rear sides of each clamping seat 405. A first portal-shaped connecting rod 41 is movably connected to the inner walls of the two left connecting blocks 410. 1. The inner walls of the two connecting blocks 410 on the right side are movably connected to a second portal-shaped connecting rod 412 that is connected to the first portal-shaped connecting rod 411. The inner wall of the left connecting block 410 is fixedly connected to the outer wall of the first portal-shaped connecting rod 411 via an inner bearing. Similarly, the inner wall of the right connecting block 410 is also fixedly connected to the outer wall of the second portal-shaped connecting rod 412 via an inner bearing. The two walls of the first portal-shaped connecting rod 411 are each provided with a slot that matches the second portal-shaped connecting rod 412. The inner wall of the slot is engaged with the rod body of the second portal-shaped connecting rod 412. Each fixture seat 405 is fixed with... A threaded sleeve 406 is provided, and a threaded adjusting rod 407 is threadedly connected to the inner wall of each threaded sleeve 406. A clamping plate 408 is fixedly connected to the bottom end of the threaded adjusting rod 407. Two guide limiting blocks 409 connected to the inner wall of the clamping base 405 are fixedly installed on the clamping plate 408. The inner wall of the clamping base 405 has two limiting grooves that are adapted to the guide limiting blocks 409, and the inner wall of the limiting groove is slidably connected to the outer wall of the guide limiting block 409. Therefore, when it is necessary to fix and flip the printed circuit board, the right rotating shaft 401, the transmission rod 402, and the servo motor are first used to fix and flip the printed circuit board. With the cooperation of the servo motor 404, the right clamp seat 405 can be stably rotated. Then, through the connection relationship between the connecting block 410, the first portal connecting rod 411, and the second portal connecting rod 412, the two portal connecting rods can be interlocked and form a whole. Thus, during processing, the left clamp seat 405 can rotate synchronously and stably with the right clamp seat 405. Finally, by setting the threaded sleeve 406, the threaded adjusting rod 407, the clamping plate 408, and the guide limit block 409, the operator can quickly and stably fix the printed circuit board to be processed, which is highly practical.

[0024] In the case implementation, an insulating, anti-slip, and wear-resistant layer was provided at the bottom end of both clamping plates 408. This design not only further enhances the clamping ability of the clamping seat, but also effectively reduces the damage to the circuit board during clamping, making it highly practical.

[0025] In the implementation of the case, the spacing adjustment component 2 is composed of bearings 201, bidirectional threaded rods 202, limiting movable blocks 204, and handwheels 203. Two bearings 201 are fixedly installed inside the slot 101. The inner walls of the two bearings 201 are fixedly connected to bidirectional threaded rods 202 extending to the outside right side of the equipment platform 1. A handwheel 203 is provided at one end of the bidirectional threaded rods 202 extending to the outside right side of the equipment platform 1. Two limiting movable blocks 204 connected to the inner walls of the slot 101 are threaded onto the bidirectional threaded rods 202. At the same time, the tops of the two limiting movable blocks 204 are respectively connected to the bottoms of the two movable plates 3, and the connection between the two is fixed. This design can perfectly solve the problem of the device being unable to adapt to different specifications of circuit boards, and its practicality is strong.

[0026] In the implementation of the case, a control panel is provided on the front side of the right-side movable plate 3. The control panel and the electronic components in this patent are electrically connected by wires, which makes it easy to operate the control panel to control the operation of the electronic components.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, through the cooperation of the right rotating shaft 401, transmission rod 402 and servo motor 404, the right clamp seat 405 can be stably rotated;

[0029] 2) Then, through the connection relationship between the connecting block 410, the first portal connecting rod 411 and the second portal connecting rod 412, the two portal connecting rods can be interlocked and form a whole, so that during processing, the left fixture seat 405 can be rotated synchronously and stably with the right fixture seat 405.

[0030] 3) Finally, by setting the threaded sleeve 406, the threaded adjusting rod 407, the clamping plate 408 and the guide limit block 409, the staff can quickly and stably fix the printed circuit board to be processed.

[0031] In summary, this clamping device for printed circuit board processing with a flipping structure, by setting up a flipping clamping mechanism 4, firstly, through the cooperation of the right rotating shaft 401, transmission rod 402 and servo motor 404, allows the right clamp seat 405 to be stably flipped. Then, through the connection relationship between the connecting block 410, the first gate-shaped connecting rod 411 and the second gate-shaped connecting rod 412, the two gate-shaped connecting rods can be interlocked and form a whole. Thus, during processing, the left clamp seat 405 can be flipped synchronously and stably with the right clamp seat 405. Finally, by setting up a threaded sleeve 406, a threaded adjusting rod 407, a clamping piece 408 and a guide limiting block 409, the operator can quickly and stably fix the printed circuit board to be processed. It is highly practical and solves the problem that the device needs to use the clamped circuit board as a conductor to adjust the angle of the two fixing frames, which can easily lead to damage to the circuit board.
