[0002] An optical lens is an optical element used to control the propagation of light. It is usually made of glass or plastic. Optical lenses achieve various optical functions by refracting, reflecting or scattering light, such as focusing, imaging, magnifying or correcting visual defects. Common lens types include convex lenses, concave lenses, and myopia and hyperopia glasses used to correct vision. In addition, there are special lenses used in optical instruments such as cameras, microscopes, and telescopes.

[0049] Working principle of this utility model:

[0050] When liquid remains on the observation glass 2 of the CNC polishing machine used for optical lens polishing, the force rod 312 drives the turntable 37, drive rod 35, and moving roller 36 to rotate clockwise. The clockwise rotating roller 36 gradually winds the pull rope 38 around the outer wall. During this process, the movable block 39 and the rubber scraper 311 move vertically downward along the limit slide bar 310 under the pull rope 38 located below. The downward moving rubber scraper 311 scrapes away the liquid on the observation glass 2. After the liquid is scraped away, the steering force applied to the force rod 312 is removed, and the spring spring 33 drives the self-winding wheel 34 to rotate back to its original position. Then, the movable block 39 and the rubber scraper 311 move vertically upward along the limit slide bar 310 under the pull rope 38 located above, quickly scraping away the liquid remaining on the observation glass 2 of the CNC polishing machine, providing convenience for the staff to observe the internal working conditions of the CNC polishing machine.
