The system employs a combination structure of substrate, cover plate, rotating buckle, limiting post and magnet. The PCB board is stably positioned by the side guidance of the limiting post and the attraction of the magnet. The rotating buckle presses the cover plate for positioning, and the magnet helps to prevent the material from falling off during unloading.
It effectively prevents PCB boards from shifting or falling during processing, ensuring processing accuracy and enabling convenient unloading operations.

[0032] Please see Figure 1-2 This utility model provides a technical solution: a positioning device to prevent PCB boards from falling off, comprising:
[0033] substrate1;
[0034] Cover plate 2, on which several machining notches 3 are provided;
[0035] The rotating buckle 5 is rotatably connected to the base plate 1 via the rotating column 4;
[0036] The limiting post 6 is inserted into the first slot 7 on the bottom surface of the cover plate 2;
[0037] The first magnet 9 is pressed into the second slot 8 on the top surface of the substrate 1;
[0038] The second magnet 11 is positioned on the cover plate 2 and is magnetically connected to the first magnet 9.
[0039] The PCB board 100 is arranged on the substrate 1 and is limited by the side abutment of the limiting post 6. The cover plate 2 covers the PCB board 100 and the rotating buckle 5 is pressed against the edge of the cover plate 2.
[0040] The height of the first magnet 9 is less than or equal to the depth of the second slot 8.
[0041] The second magnet 11 is positioned in the positioning groove 10 on the bottom surface of the cover plate 2, and its height is less than or equal to the depth of the positioning groove 10.
[0042] The limiting post 6 includes a support block 12 and a guide block 13 arranged in a stepped manner. The support block 12 is raised and abuts against the bottom surface of the rotating buckle 5, and the guide block 13 passes through the rotating buckle 5 and provides axial limiting. The edge of the cover plate 2 is provided with a clearance opening 14 corresponding to the rotation range of the rotating buckle 5. The sidewall of the clearance opening 14 is arc-shaped. This improves the stability of the rotating buckle 5 in pressing and positioning the cover plate 2.
[0043] The working principle of the positioning device for preventing PCB board from falling in this embodiment includes: In use, a first magnet 9 is placed in a second slot 8, a PCB board 100 is placed on a substrate 1 and guided and limited laterally by a limiting post 6, a cover plate 2 is pressed onto the PCB board 100, and the limiting post 6 is inserted into the first slot 7. A rotating buckle 5 rotates along the clearance opening 14 and presses and positions the cover plate 2. During this process, the two magnets magnetically attract and position the cover plate 2, PCB board 100, and substrate 1, preventing displacement or falling during processing. To prevent collisions and interference between structures during processing, ensuring processing accuracy, the PCB board 100 can then be processed through the processing notch 3. After processing, rotate the rotating buckle 5 to detach it from the cover plate 2. Hold the cover plate 2 and pull it outward. The magnets on both ends of the PCB board 100 will position the PCB board 100 and the cover plate 2, allowing the PCB board 100 to be pulled out together. Then flip the cover plate 2, remove the first magnet 9, and the PCB board 100 can be taken out. This achieves quick and drop-proof PCB board unloading.
