Description

Technical Field

[0001] The utility model relates to the field of PCB board positioning devices, in particular to a PCB board positioning device with higher efficiency. Background Art

[0002] PCB printed circuit board is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Since it is made using electronic printing technology, it is called a "printed" circuit board. PCB boards need to be fixed during installation, production, and testing, such as punching holes at the corners of PCB boards, electrical testing, and welding. In this process, positioning devices are required to lock the position of the PCB board to prevent it from being dislocated or moved.

[0003] In the prior art, a patent document with announcement number CN216464174U discloses a PCB board positioning device, and simultaneously discloses that a bracket is rotatably installed inside the U-shaped seat, and a support is installed at the bottom of the bracket, a positioning box is fixed on the top of the support, and a servo motor is installed on the outer wall of one side of the positioning box, and bearing seats are installed on both sides of the bottom of the positioning box, and a bidirectional screw rod is rotatably installed inside the bearing seat, and one end of the bidirectional screw rod is fixedly connected to the output end of the servo motor; however, in actual application, when positioning the PCB board, it is necessary to drive the positioning blocks on both sides to press down at the same time to fix the PCB board, which will cause the positioning blocks on both sides to cover the PCB board. When the surface of the PCB board needs to be processed, the covered part cannot be processed, and the position of the PCB needs to be continuously adjusted to fully process its surface, which will affect the processing process.

[0004] The Chinese utility model patent with application number 202321315937.9 proposes a PCB board positioning device to solve the above problems, but there are still some shortcomings: it can only realize the clamping positioning of two sides, but for the other two sides, it is only fixed by the positioning groove, which directly leads to the size of the PCB board on this side being limited, and only the PCB board with a fixed size on this side can be processed, and the applicable processing range is limited. At the same time, if the size of the positioning groove is exactly equal to the size of one side of the PCB board, it will cause the PCB board to be placed in the positioning groove. It is not convenient and the size needs to be adjusted. If a size margin is left for the convenience of placement, there will be some movement space for the PCB board, resulting in insufficient positioning accuracy;

[0005] Based on this, the utility model proposes a more efficient PCB board positioning device to solve the above problems. Utility Model Content
