[0002] With the advancement of science and technology and the continuous improvement of the quality of life, the application fields of integrated circuits are becoming more and more extensive. Among them, printed circuit boards used in the integrated circuit packaging process can not only be used for electrical connection, but also can be used to carry chips or other electronic components. At present, the common printed circuit board surface treatment process requires a burr grinding device to grind the circuit board during etching.

[0003] In the prior art, in the patent application with the authorization publication number CN218658156U and the authorization publication date 2023-03-21, entitled "A burr removal device for circuit board production", the circuit board is moved by moving the movable rod or the push rod on one side of the U-shaped seat, and the clamping mechanism on the other side is used for installation. After use, the adjustment rod is turned upward, and the reset spring cooperates with the rotation of the adjustment rod to drive the pressing plate to move upward, and the polished circuit board is removed, or the direction is changed to continue polishing;

[0004] In actual use of the above device, when the burrs on one side of the circuit board are polished, it is necessary to manually release the limiting function of the circuit board and then remove the circuit board and change the direction. The operation is cumbersome and it is inconvenient to use the polishing wheel to evenly polish the side of the circuit board.

[0005] Therefore, we propose a device for controlling the burr grinding of circuit boards to solve the above-mentioned problems. Utility Model Content
