meanwhile, the rotation of the rotating shaft 16 drives the second rotating rod 701 and the cam 702 to rotate, when the tip of the cam 702 abuts against the side wall of the rotating plate 602, the rotating plate 602 is pushed to rotate along the first rotating rod 601, and simultaneously, the rotation of the first rotating rod 601 drives the rotation of the gear 801, so that the rack 802 slides along the guide rod 902, the third spring 904 is compressed, when the tip of the cam 702 crosses the side wall of the rotating plate 602, the rotating plate 602 and the first rotating rod 601 can rotate and reset under the action of the third spring 904, so that the rotating plate 602 can swing back and forth, and the swing of the rotating plate 602 drives the mounting plate 603 and the soft brush 604 to swing synchronously, so that the surface of the lens can be cleaned while spraying water, so that the cleaning effect is better, and the accuracy of the test result is ensured;
and after the water spraying cleaning is finished, the first electric valve 304 is closed, the second electric valve 1001 is opened, the electric heating ring 1004 is electrified, at the moment, external air enters after being filtered by the second filter screen 1003, is heated by the electric heating ring 1004 and is sprayed on the surface of the lens through the water spraying pipe 310, so that water stains on the surface of the lens can be dried, and the accuracy of a test result is ensured.
