[0003] Therefore, in order to improve the alignment efficiency and alignment accuracy during circuit board processing, protect the circuit board and improve the processing accuracy, a positioning device and method for circuit board production and processing are proposed. Summary of the Invention

The sliding of the movable plate on the base and the up and down adjustment of the lifting plate can adapt to circuit boards of different sizes, ensuring that the circuit board is in the accurate processing position each time it is clamped, effectively improving the alignment accuracy of circuit board production and processing;

[0019] 2. The two sets of elastic telescopic rods in the positioning and fixing assembly can slowly apply thrust to the circuit board, so that the clamping force of the clamping plate on the circuit board gradually increases. The slow application of flexible force can ensure that all parts of the circuit board are evenly stressed, avoiding local excessive pressure, thereby protecting the integrity and functionality of the circuit board;

[0020] 3. In addition, during the clamping process, the flexible force of the elastic telescopic rod can better adapt to the slight undulations and irregularities on the surface of the circuit board. The flexible force slowly applied by the elastic telescopic rod can adjust as the shape of the circuit board surface changes, reducing stress concentration and increasing the service life of the circuit board.

[0021] 4. The control of the cylinder and the rotation of the knob are simple to operate, which can quickly clamp and loosen the circuit board, reducing the difficulty and time of the operator's operation and improving production efficiency. The alignment device can adapt to circuit boards of different sizes and thicknesses. Whether it is a larger circuit board or a thicker circuit board, clamping and alignment can be achieved by adjusting the moving plate and the lifting plate, which improves the versatility and adaptability of the device in the production line.

[0037] In this embodiment, specifically: a guide telescopic rod 238 is installed between the isolation box 231 and the clamping plate 234 , and the guide telescopic rod 238 and the guide rail 237 are arranged in parallel.

[0038] In this embodiment, specifically, a second elastic telescopic rod 236 is hingedly connected between the side wall of the isolation box 231 and the slider 233 , and the second elastic telescopic rod 236 and the first elastic telescopic rod 232 have the same structure.

[0039] In this embodiment, specifically: a cylinder 24 is fixedly mounted on the base 21 , and a telescopic end of the cylinder 24 is fixedly connected to the movable plate 22 .

[0041] In this embodiment, specifically: a pressing block 33 is fixedly connected to the lifting plate 32 , and the pressing block 33 presses the circuit board.

[0042] In this embodiment, specifically: a knob 36 is fixedly connected to the top of the threaded rod 34 .

[0043] In this embodiment, specifically: a guide slot 211 is provided on the base 21 , a guide block 221 is fixedly connected to the movable plate 22 , and the guide block 221 is slidably connected in the guide slot 211 .

[0044] Working principle or structural principle: When positioning the circuit board, first place the circuit board on the workbench 1 so that the circuit board is placed between the alignment fixing component 2 and the positioning component 3. After the cylinder 24 is started, its telescopic end pushes the movable plate 22 to slide on the base 21, and the guide block 221 on the movable plate 22 slides in the guide groove 211 of the base 21 to ensure the smooth movement and direction of the movable plate 22; when the base 21 continues to move, the clamping plate 234 first abuts against the circuit board, and the elastic telescopic rod 1 232 and the elastic telescopic rod 236 in the isolation box 231 start to work, and the spring 241 is compressed, exerting an outward force on the movable rod, pushing the slider 2 33 slides on the guide rail 237 in the isolation box 231. At the same time, the elastic telescopic rod 236 hinged between the side wall of the isolation box 231 and the slider 233 also provides a similar pushing effect. The slider 233 pushes the clamping plate 234 through the connecting rod 235 to gradually apply thrust to the circuit board and finally clamp the circuit board; in this process, the guide telescopic rod 238 is arranged parallel to the guide rail 237, providing additional guidance and support for the movement of the clamping plate 234, ensuring the linearity and stability of the movement of the clamping plate 234; finally, the circuit board is clamped and fixed between the fixing component 2 and the positioning component 3 under the elastic force of the two sets of telescopic rods, providing stable alignment and fixation for the production and processing of the circuit board.

[0045] When it is necessary to fix the longitudinal direction of the circuit board, the staff rotates the knob 36 on the top of the threaded rod 34 to rotate the threaded rod 34 on the positioning frame 31. Since the threaded rod 34 is threadedly connected to the lifting plate 32, and the guide rod 35 at the bottom of the lifting plate 32 slides on the positioning frame 31, the rotation of the threaded rod 34 is converted into the up and down movement of the lifting plate 32. When the lifting plate 32 moves to the appropriate position, the pressure block 33 on the lifting plate 32 rests on the circuit board and presses the circuit board in the longitudinal direction.
