Spherical lens polishing device

Abstract

The invention discloses a spherical lens polishing device, and belongs to the field of optical lens manufacturing. The spherical lens polishing device comprises a polishing head used for polishing thespherical lenses, a first servo motor used for driving the polishing head to rotate, a lifting polishing head mounting mechanism used for adjusting the vertical height of the polishing head, a secondservo motor used for rotating and moving the polishing head to adjust a polishing station, a lens mounting table, a lens table base, a force measuring sensor and a main controller. During operation,the main controller controls the second servo motor to rotate and move the polishing head above the spherical lens, the main controller controls the lifting polishing head mounting mechanism to vertically move the polishing head on the spherical lens, and the main controller controls the first servo motor to rotate and enables the polishing head to buff the spherical lens. According to the spherical lens polishing device, the pressure value of the polishing operation is measured online through the force measuring sensor, the uniformity of the pressure of the polishing operation is calculated,whether the polishing is completed or not is judged, the polishing operation is controlled to stop or continue is controlled, and the overall polishing operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of spherical mirror production, in particular to a spherical mirror polishing device. Background technique [0002] There are three main methods of manufacturing aspheric lenses: the first is grinding aspheric lenses. It is to directly use optical glass blanks to grind out the aspheric mirror of the required shape. The process is very difficult and the cost is very high. Almost all the earliest aspheric mirrors were made in this way. The second is molded aspheric lenses: metal casting technology is used to directly press molten optical glass / optical resin. This manufacturing process is relatively low in cost, and most of the molded aspheric lenses are made of optical resin. It is extremely rare because optical glass is a material that is not suitable for the production of products by molding process, because the molding process will make it difficult to remove the air bubbles in the glass, and the yield rate will be ...
