Description

Technical Field

[0001] The utility model relates to the technical field of mold core polishing, in particular to an intelligent aspherical mold core polishing device. Background Art

[0002] With the development of optoelectronic technology, aspheric lenses are increasingly used in optical systems to improve the shortcomings of large aberrations, small field of view, and large volume of optical systems in traditional spherical lens optical systems. There are two commonly used aspheric lens manufacturing technologies: cold processing and hot pressing. Cold processing technology includes grinding and polishing the lens blank. This technology has low production efficiency and is often used in the manufacture of large-diameter optical lenses in the astronomical and military fields. Hot pressing technology uses high-precision molds to heat the lens blank and apply a certain pressure when the glass lens is in a high elastic state. After a certain period of pressure maintenance and cooling, the finished lens can be directly formed. The compression molding technology has high production efficiency and is suitable for mass production of civilian lenses such as automotive lenses, security lenses, and mobile phone lenses. However, compression molding technology requires precision molds. The surface accuracy and surface roughness of the mold surface directly determine the quality of aspheric lenses in compression production. Common mold processing methods are grinding and polishing. First, the mold blank is ground using a high-precision grinder, and then the mold surface roughness, surface accuracy that does not meet the requirements, and surface sub-damage caused by grinding are repaired using polishing equipment. The polishing accuracy directly determines the accuracy of the mold surface.

[0003] At present, when polishing aspheric mold cores, manual handheld angle grinders are usually used for processing. However, this direction not only requires manual maintenance of precise force, but also requires workers to have long-term endurance, which is not suitable for large-scale aspheric mold core polishing work.

[0004] Therefore, we made improvements and proposed an intelligent aspheric mold core polishing device. Utility Model Content
