[0023] Specific implementation examples are given below.

[0024] Please see Figures 1-4This utility model provides a circuit board clamping device for hardware production, including a base plate 1; a pair of sliding grooves 11 are formed on the top of the base plate 1; the sliding grooves 11 are symmetrically arranged on both sides of the base plate 1 and have the same structure; a first slider 12 is slidably connected to the side wall of the sliding groove 11; a rubber pad 13 is fixedly connected to the side wall of the first slider 12; a bearing plate 14 is fixedly connected to the side wall of the first slider 12; an anti-slip pad 15 is fixedly connected to the side wall of the bearing plate 14; a bracket 16 is fixedly connected to the side wall of the bracket 16; a screw 17 is threadedly connected to the side wall of the bracket 16; the screw 17 passes through the wall of the bracket 16 and is threadedly connected to it; a clamping plate 18 is rotatably connected to the end of the screw 17; a guide rod 19 is fixedly connected to the side wall of the bracket 16; a second slider 110 is sleeved on the outside of the guide rod 19; the second slider 110 is fixedly connected to the clamping plate 18; in use, first hold the bearing plate 14 and apply a certain force to make the first slider 12 slide in the sliding groove 11. The distance between the two support plates 14 is adjusted by sliding on the side wall. After adjustment, the first slider 12 can be fixed by the friction generated by the contact between the rubber pad 13 and the slide groove 11. Then, the circuit board is placed on the two support plates 14 so that it contacts the anti-slip pad 15 and generates a certain friction force, which can pre-fix the circuit board. Then, by gripping and rotating the screw 17, the screw 17 pushes the clamping plate 18 down and close to the circuit board, thereby clamping and fixing the circuit board. At the same time, when the clamping plate 18 moves, the second slider 110 can slide on the side wall of the guide rod 19 to limit the movement of the clamping plate 18 and prevent it from rotating. In this process, it can clamp and fix circuit boards of different sizes and specifications, improve the application range of the base plate 1, and the anti-slip pad 15 can play a pre-fixing role when clamping the circuit board, thereby increasing the stability of the circuit board before clamping and also increasing the fixing effect of the circuit board.

[0025] Furthermore, such as Figures 1-4As shown, the bottom of the base plate 1 is provided with a fixed seat 2; the top of the fixed seat 2 is rotatably connected to a column 21; the column 21 is fixedly connected to the base plate 1; multiple slots 22 are evenly provided on the side wall of the fixed seat 2; a fixed frame 23 is fixedly connected to the side wall of the column 21; a first spring 24 is fixedly connected to the side wall of the fixed frame 23; an insert 25 is fixedly connected to the end of the first spring 24; a pull plate 26 is fixedly connected to the side wall of the insert 25; the pull plate 26 penetrates the wall of the fixed frame 23 and is slidably connected to it; in use, first hold the pull plate 26 and pull it to pull the insert 25 out from the side wall of the slot 22. Then, the base plate 1 can be pulled to make the column 21 rotate on the side wall of the fixed seat 2. After the rotation is completed, the insertion block 25 can be aligned with the position of one of the slots 22. Then, by releasing the pull plate 26, the elasticity of the first spring 24 can push the insertion block 25 into the side wall of the slot 22, thereby fixing the column 21 and preventing it from rotating, so as to complete the direction adjustment of the base plate 1. In this process, it can play the role of rotation adjustment of the base plate 1 during use, increase the processing effect of different circuit boards, thereby increasing the application range and application scenarios of the base plate 1, and improving the convenience of circuit board processing.

[0026] Furthermore, such as Figures 1-4 As shown, an air cylinder 3 is fixedly connected to the side wall of the bracket 16; a piston rod 31 is slidably connected to the inner side wall of the air cylinder 3; a connecting block 32 is threadedly connected to the outer side of the screw 17; the connecting block 32 and the piston rod 31 are fixedly connected; an air outlet pipe 33 is fixedly connected to the side wall of the air cylinder 3; during use, as the screw 17 is rotated to descend, the connecting block 32 can simultaneously push the piston rod 31 to move inside the air cylinder 3, using the piston rod 31 to squeeze the gas inside the air cylinder 3, allowing the gas to be discharged to the outside through the air outlet pipe 33, thereby blowing air onto the circuit board. When the screw 17 is rotated to reset, air can be drawn back into the air cylinder 3 through the air outlet pipe 33. During this process, it can clean the dust adhering to the surface of the circuit board, reduce the adhesion of dust on the surface of the circuit board, and thus improve the processing effect of the circuit board.

[0027] Furthermore, such as Figures 1-4 As shown, multiple elastic pieces 4 are fixedly connected to the side wall of the slot 22; the elastic pieces 4 are evenly distributed on the side wall of the slot 22 and have the same structure; a rubber strip 41 is fixedly connected to the side wall of the elastic piece 4; in use, when the insert 25 is inserted into the side wall of the slot 22, the insert 25 can push the elastic pieces 4 on both sides open, and at the same time, the elasticity of the elastic pieces 4 can push the rubber strip 41 towards the side wall of the insert 25, so that it abuts against the side wall of the insert 25 and generates a certain friction force to fix the insert 25. In this process, the fixing effect of the insert 25 on the side wall of the slot 22 can be increased, the firmness and stability of the column 21 during use can be increased, and the wobbling of the insert 25 in the slot 22 due to the elasticity of the first spring 24 can be reduced.

[0028] Furthermore, such as Figures 1-4 As shown, the bottom of the fixing seat 2 is provided with multiple grooves 5; the grooves 5 are evenly distributed on the bottom of the fixing seat 2 and have the same structure; a second spring 51 is fixedly connected to the side wall of the groove 5; a rubber block 52 is fixedly connected to the end of the second spring 51; when in use, by placing the fixing seat 2 on the surface of an object, the compression between the surface of the object and the fixing seat 2 can cause the second spring 51 to extend and retract, and at the same time, the elasticity of the second spring 51 can push the rubber block 52 against the surface of the object, so that it can make full contact and generate a certain friction force. In this process, the fixing effect of the fixing seat 2 on the surface of the object can be increased, the anti-slip effect of the fixing seat 2 can be increased, and thus the fixing effect and stability of the base plate 1 during circuit board processing can be improved.

[0029] Furthermore, such as Figures 1-4 As shown, a pair of iron wires 6 are symmetrically fixed to the side wall of the anti-slip mat 15. In use, the walls of the anti-slip mat 15 can be fixedly connected by the iron wires 6, and the whole mat can be connected together. In this process, the anti-slip mat 15 can be made more tear-resistant, and the anti-slip mat 15 can be fixed, thereby improving the service life of the anti-slip mat 15.

[0030] Working principle: In use, first, hold the support plate 14 and apply a certain force to make the first slider 12 slide on the side wall of the slide groove 11 to adjust the distance between the two support plates 14. After adjustment, the first slider 12 can be fixed by the friction generated by the rubber pad 13 contacting the slide groove 11. Then, the circuit board is placed above the two support plates 14, so that it contacts the anti-slip pad 15 and generates a certain friction, which can pre-fix the circuit board. Then, by holding and rotating the screw 17, the screw 17 pushes the clamping plate 18 down and closer to the circuit board, thereby fixing it. The circuit board is clamped and fixed. Simultaneously, when the clamping plate 18 moves, the second slider 110 slides on the side wall of the guide rod 19 to limit the movement of the clamping plate 18 and prevent it from rotating. In use, first grasp the pull plate 26 and pull it to pull the insert 25 out of the side wall of the slot 22. Then, pull the base plate 1 to make the column 21 rotate on the side wall of the fixing seat 2. After rotation, the insert 25 can be aligned with one of the slots 22. Then, by releasing the pull plate 26, the elasticity of the first spring 24 can push the insert 25 into the side wall of the slot 22, thus... The column 21 is fixed to prevent rotation, thus adjusting the orientation of the base plate 1. During use, as the screw 17 descends, the connecting block 32 pushes the piston rod 31 within the air cylinder 3, forcing the gas out of the cylinder through the outlet pipe 33, thereby blowing air into the circuit board. When the screw 17 is rotated back to its original position, air can be drawn back into the cylinder 3 through the outlet pipe 33. During use, when the insert 25 is inserted into the side wall of the slot 22, the insert 25 can push open the elastic plates 4 on both sides, simultaneously utilizing the elastic... The elasticity of the plate 4 can push the rubber strip 41 against the side wall of the insert 25, so that it abuts against the side wall of the insert 25 and generates a certain friction force, thus fixing the insert 25. When in use, by placing the fixing seat 2 on the surface of the object, the compression between the surface of the object and the fixing seat 2 can cause the second spring 51 to extend and retract. At the same time, the elasticity of the second spring 51 can push the rubber block 52 against the surface of the object, so that it makes full contact and generates a certain friction force. When in use, the anti-slip pad 15 wall can be fixedly connected by the wire 6, so that the whole is connected together.
