Device for preparing optical-grade friction-resistant nanometer film layer on outer surface of PC welding ball cover

The utility model relates to a device for preparing an optical-grade friction-resistant nano film layer on the outer surface of a PC (Poly Carbonate) welding ball cover, which is characterized by comprising a support frame, an electric cabinet for controlling equipment to work, a spraying mechanism, a suction mechanism, a fixing mechanism for fixing the PC welding ball cover, and a water pan, a rotary motor on the fixing mechanism drives the PC welding ball cover to rotate, then the PC welding ball cover is sprayed, accumulated liquid suction is carried out on a gap and a base of the PC welding ball cover after spraying is finished, a laser range finder is installed on the suction mechanism, and the situation that accumulated liquid suction is not thorough due to elliptic change of the PC welding ball cover and coaxiality deviation of a rotary shaft can be avoided. And the PC welding ball cover is taken out and cured after suction is finished. According to the utility model, the problems of ellipse change of
