Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to a workbench steering structure for edge grinding of an optical lens of a projection lens. Background Art

[0002] With the high precision of projection lenses for projectors, various optical glasses with low refractive index and high dispersion are used as lens materials for projection lenses. Optical glasses are made of high-purity silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium and other oxides mixed according to a specific formula, melted at high temperature in a platinum crucible, stirred evenly with ultrasound to remove bubbles; then slowly cooled for a long time to prevent internal stress in the glass block. The cooled glass block must be measured by optical instruments to check whether the purity, transparency, uniformity, refractive index and dispersion meet the specifications. Qualified glass blocks are heated and forged to form optical lens blanks. The optical lens blank needs to be polished around its periphery so that the outer diameter of the original lens is ground to the specified outer diameter before it can be used.

[0003] When processing optical lenses, it is necessary to grind the edges of the optical lenses to facilitate the positioning of the optical lens surface during the later processing. Therefore, optical lens edge grinding is the most important process in optical lens processing. The higher the accuracy of optical lens edge grinding, the more accurate the processing of the optical lens can be.

[0004] In the prior art, in order to improve the efficiency of edge grinding, an optical lens is generally driven to rotate by a motor with a relatively high rotation speed so that the edge of the optical lens contacts a rotating grinding wheel to improve the efficiency of edge grinding of the optical lens. Another commonly used method is to set a plurality of rotating grinding wheels around the lens and grind the optical lens simultaneously by the plurality of grinding wheels, thereby further improving the efficiency of edge grinding.

[0005] However, in actual production, this method can improve the efficiency of edge grinding to a certain extent. However, since the rotating grinding wheel may be out of sync when moving toward the optical lens, part of the grinding wheel will not be able to contact the optical lens, resulting in idling. This part of the grinding wheel is actually useless and is a pure waste of resources. Therefore, in order to solve the above problem, a workbench steering structure for projection lens optical lens edge grinding is proposed. Utility Model Content
