Description

Optical lens thickness grinding fixing mechanism Technical Field The utility model relates to the technical field of optical lens processing equipment, in particular to an optical lens thickness grinding fixing mechanism. Background The optical lens is a transparent medium designed based on the optical principle, and has the main function of changing the propagation direction of light rays through refraction or reflection so as to realize the purposes of focusing, imaging or correcting eyesight and the like. The optical lens is processed by grinding its thickness, i.e., by a series of physical and chemical processes, to achieve the desired accuracy and surface quality. At present, when an optical lens is processed, a special adhesive is adopted to bond the optical lens on a grinding fixing seat, and when the adhesive is used, if the thickness of the adhesive is uneven, the lens is easy to incline, so that the error of the rear grinding face is caused. Therefore, we propose to design an optical lens thickness grinding fixing mechanism.
