Aspheric optical lens compression molding machine

Abstract

The invention relates to the field of optical lens production devices, and especially relates to an aspheric optical lens compression molding machine. The aspheric optical lens compression molding machine is characterized in that the compression molding machine comprises a frame, a sealed molding cavity arranged on the frame and a plurality of molding stations sequentially arranged in the sealed molding cavity, and the compression molding machine further comprises profiling units fixedly arranged on the upper end surface of the sealed molding cavity, located above the molding stations and usedfor heating or cooling or pressing molding molds at the molding stations, and a transfer unit arranged in the sealed molding cavity and used for simultaneously forwards moving every molding mold on the corresponding station for a station distance. The plurality of molding stations and profiling units are arranged in the sealed molding cavity of the aspheric optical lens compression molding machine, so optical lenses can be strictly subjected to one-shot compression molding under process conditions, the qualified rate is high, and a problem that shaped lenses cannot be processed by grinding issolved.

Description

technical field [0001] The invention relates to the field of optical lens production equipment, in particular to an aspherical optical lens molding machine. Background technique [0002] In recent years, with the rapid development of the optoelectronic industry, the application and demand of glass optical devices have become more and more extensive. At present, the domestic optical device manufacturing is still subject to developed countries such as Japan and Germany. Domestic glass optical device manufacturers almost rely on imported processing equipment and adopt foreign processing technology. This has become the biggest "pain point" in the manufacture of glass optical devices in my country for a long time. Existing glass optical lenses are processed by grinding, but the grinding efficiency is low, and special-shaped lenses such as aspherical surfaces cannot be processed by grinding. Contents of the invention [0003] The purpose of the present invention is to overcom...

Problems solved by technology

[0003] The object of the present invention is to overcome the above disadvantages and provide a molding machine for aspherical optical lenses. The molding machine is provided with a plurality of molding stations and molding units in the molding sealed cavity, and can process the optical lenses strictly according to the process conditions. One-time compression molding, high pass rate, solves the problem that special-shaped lenses cannot be processed by grinding
