[0002] The pressure head is a tool used for grinding precision components such as sensor modules. The automatic positioning pressure head can accurately position itself to the specific location that needs to be ground.

[0003] The existing patent CN114178977A discloses a grinding device with continuously adjustable grinding pressure. The optical fiber connector is fixed by a clamping mechanism. First, the desired pressure value is set. During the operation, the pressure value is detected in real time by a pressure detection device. The lifting motor is controlled by a PID closed-loop algorithm, thereby stabilizing the vertical grinding pressure between the optical fiber to be ground and the grinding disc on the clamping mechanism, so as to achieve a better grinding effect.

[0004] The existing device clamps the sensor module inside the fixture slot and grinds it with a pressure head. Due to prolonged use of the pressure head, the pressure head and the fixing device may slip, and the drive mechanism will not be able to drive the pressure head to rotate. Utility Model Content
