[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] This utility model discloses a PCB circuit board alignment and clamping device, according to the attached... Figures 1-4 As shown, the device includes a support frame 1, a clamp 2, and a circuit board 3. The clamp 2 is mounted on the support frame 1, and the circuit board 3 is clamped by the clamp 2. The clamp 2 includes a slider 21 and a clamping member 22. A fixing sleeve 212 is fixedly connected to the rear side of the slider 21. A first electromagnetic sensor 2122 and a second electromagnetic sensor 2123 are fixedly inserted into the outside of the fixing sleeve 212. The first electromagnetic sensor 2122 and the second electromagnetic sensor 2123 are spaced apart along the axial direction of the fixing sleeve 212. The inner side of the fixed sleeve 212 is integrally formed with a rod 213, and a buffer spring 214 is sleeved on the outer side of the rod 213. A sleeve 225 is welded to the rear side of the clamping member 22. The sleeve 225 is inserted into the inner side of the slider 21 and movably sleeved on the rod 213. The rear end of the sleeve 225 abuts against the buffer spring 214. A sensing block 2252 is welded to the outer side of the sleeve 225. The sensing block 2252 cooperates with the first electromagnetic sensor 2122 and the second electromagnetic sensor 2123. The signal of the electromagnetic sensor is triggered by the sensing block 2252 to control the clamping force of the clamp 2.

[0020] Through the cooperation of the first electromagnetic sensor 2122, the second electromagnetic sensor 2123 and the sensing block 2252, the displacement of the clamping component 22 can be monitored in real time, thereby accurately controlling the clamping force and avoiding damage to the circuit board 3 due to excessive force or unstable clamping due to insufficient force; the buffer spring 214 can provide buffering during the clamping process and reduce the damage to the circuit board 3 caused by rigid contact; the threaded rod 12 drives the slider 21 to move, and combined with the guiding effect of the slide rod 13, the chuck 2 is easy to adjust and can adapt to circuit boards 3 of different specifications; According to the appendix Figures 1-2 As shown, the support frame 1 further includes a fixed frame 11, a threaded rod 12, and a sliding rod 13. A support bar 111 is welded to the top of the fixed frame 11, and a sleeve rod 112 is welded to the bottom of the support bar 111. The support bar 111 supports the edge of the circuit board 3. The threaded rod 12 is inserted into the inner side of the support frame 1 via a bearing, and the threaded rod 12 is threadedly connected to the slider 21. Rotating the threaded rod 12 drives the slider 21 to move axially. The sliding rod 13 is fixedly inserted into the inner side of the support frame 1 and movably inserted into the inner side of the sleeve rod 112, improving the stability of the fixed frame 11.

[0021] According to the appendix Figures 1-4 As shown, furthermore, support rods 211 are welded to both sides of the slider 21. The support rods 211 are movably sleeved on the outside of the slider 13 to ensure the stability of the slider 21 during movement. A bolt 2121 is threaded into the outside of the fixed sleeve 212. A groove 2251 is opened on the outside of the sleeve 225. The end of the bolt 2121 is inserted into the inside of the groove 2251, which guides and limits the movement of the sleeve 225 and prevents the sleeve 225 from rotating.

[0022] According to the appendix Figures 1-4 As shown, the clamping member 22 has a slot 221 at its top, which slides and engages with the bottom of the support bar 111. A rubber clamping block 222 is adhered to the top of the clamping member 22 for flexibly clamping the circuit board 3 and preventing scratches. A sliding sleeve 223 is welded to the bottom of the clamping member 22, which is movably sleeved on the outside of the sliding rod 13. A limiting rod 224 is welded to the rear side of the clamping member 22. The limiting rod 224 is located outside the sleeve 225 and is movably inserted into the inside of the slider 21, further improving the stability of the clamping member 22 during movement.

[0023] Working principle: In use, the circuit board 3 is placed on the support bar 111. Rotating the threaded rod 12 drives the slider 21 to move, causing the clamping member 22 to move closer to the circuit board 3. The clamping block 222 contacts the circuit board 3 and applies clamping force. During clamping, the sleeve 225 compresses the buffer spring 214 and moves backward. The sensing block 2252 moves with the sleeve 225. When the sensing block 2252 triggers the first electromagnetic sensor 2122, it indicates that the clamping force has reached the preset minimum value; when the sensing block 2252 triggers the second electromagnetic sensor 2123, it indicates that the clamping force has reached the preset maximum value. At this time, the rotation of the threaded rod 12 can be stopped, achieving precise clamping. The elastic force of the buffer spring 214 can maintain a stable clamping force while avoiding damage to the circuit board 3 due to excessive force.
