Furthermore, a pressure sensor is arranged in the active self-adaptive flange assembly and used for acquiring a real-time pressure value between flanges at two ends of the active self-adaptive flange assembly;

According to the intelligent self-dust-absorption grinding and polishing terminal device, the real-time pressure value between the flanges at the two ends of the active self-adaptive flange component is obtained through the pressure sensor arranged in the active self-adaptive flange component, and the real-time pressure value is the surface contact pressure for grinding and polishing; the pressure sensor is in signal connection with the control terminal, and when the real-time pressure value is larger than the preset pressure value, the control terminal controls the pneumatic mechanical arm to stop working, so that the situation that the real-time pressure value is larger than the preset pressure value, the pneumatic mechanical arm still drives the self-dust-collection eccentric grinding machine to move, and the thin-wall equipment surface is collided to cause permanent damage to the equipment is avoided.

Further, a mounting seat is further arranged between the active self-adaptive flange assembly and the self-dust-absorption eccentric grinding machine, and a networked camera assembly is arranged on the mounting seat and is in signal connection with the control terminal;

Compared with the prior art, the invention has the beneficial effects that:

1. the invention relates to a pneumatic mechanical arm which is suitable for equipment with various specifications and types, has constant surface contact pressure and can be used for continuously grinding and polishing, wherein the surface contact pressure is preset on a tablet personal computer; when the contact pressure exceeds a set value, the air path of the pneumatic mechanical arm is automatically switched to stop moving, so that the permanent damage of the equipment caused by collision with the surface of the thin-wall equipment is avoided; in the continuous grinding and polishing process, the uniform grinding quality of the surface of the equipment is ensured;

3. the method adopts the laser ranging sensing assembly to measure the thickness of the removed coating in real time on line, and displays the thickness value of the removed coating on a tablet personal computer in real time; when the thickness value of the removed coating is reduced, an operator is prompted to replace the sanding disc of the polishing machine head in time, so that the production efficiency is effectively improved, and the material consumption cost is reduced.

4. The present invention employs an electrostatic scavenging device which attracts positive charges in the air stream when the surface of the equipment is negatively charged and attracts negative charges in the air stream when the surface of the object is positively charged, thereby neutralizing the static electricity on the surface of the object and avoiding the risk of explosion of metal dust caused by high-pressure electrostatic precipitation.
