AI Technical Summary
Technical Problem
In existing automatic sanding systems, the pressure sensor is eccentric, which leads to inaccurate control of sanding pressure, potentially resulting in incomplete sanding or scratches on the paint surface.
Method used
By employing a thrust device and a pressure sensor in conjunction with a compensation mechanism, the grinding pressure is detected in real time and the output of the thrust device is dynamically adjusted. The compensation mechanism provides reverse torque to counteract the eccentricity, ensuring precise control of the grinding pressure.
Benefits of technology
It achieves precise pressure control during the sanding process, avoiding problems such as incomplete sanding or paint scratches, and improving sanding quality and reliability.

Abstract
The application relates to a polishing device and an automatic polishing system for vehicle body paint surface defects, wherein the polishing device is provided with a thrust device and a pressure sensor; the thrust device applies a thrust force to an installation base plate, the installation base plate drives a grinding head to uniformly press on the vehicle body paint surface defects; the pressure sensor detects the polishing pressure during polishing, realizes real-time feedback of the polishing pressure, and dynamically adjusts the output of the thrust device. A compensation mechanism is arranged, and the thrust device is arranged between the polishing assembly and the compensation mechanism; a second acting force applied by the compensation mechanism provides a torque to the installation base plate, the direction of the torque is opposite to the torque direction of the polishing assembly to the installation base plate, the error of the pressure sensor caused by eccentricity is avoided, the accurate control of the polishing pressure during polishing is realized, and problems such as incomplete polishing or paint surface scratching are avoided.
