Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, in particular to a cold processing, polishing and filtering device for optical lenses. Background Art

[0002] A lens is an optical element made of transparent material with a spherical surface. There are two types of lenses: plastic lenses and glass lenses. The lens processing technology is divided into hot processing and cold processing. Because glass is easy to stick to the mold surface during hot processing, and the product is also prone to pores and cold mold marks, lenses are mostly cold processed. The lens needs to be polished during the cold processing stage. Before polishing, the lens needs to be coarsely ground, then finely ground, and finally polished. Polishing fluid is needed during the process. The polishing fluid takes away the worn particles during the coarse and fine grinding process.

[0003] In the prior art, when polishing a lens, usually only a single nozzle is used to spray polishing liquid to remove the worn particles. However, it is difficult for a single nozzle to completely remove the debris on the lens while polishing, resulting in damage to the lens surface during polishing, which reduces the quality of the lens. In addition, the polishing liquid needs to be re-filtered after use. However, when filtering the polishing liquid in the prior art, the filter screen is often easily clogged due to the different sizes of particles, which reduces the filtration efficiency and requires manual disassembly and cleaning before continued use, which is time-consuming and labor-intensive.
