Technical Field
[0001] The utility model belongs to the technical field of lens processing, and in particular relates to a polarizing film corner grinding device. Background Art
[0002] In the production process of some 3D glasses, polarizers are usually needed as lenses. The polarizers need to be attached to resin plates, and then the resin plates are cut to obtain the required lens shape. After machining and cutting, burrs are usually left on the edges of the lenses, which affects subsequent processing and use. Polishing is usually required. The existing polishing method is to polish the edges of the lenses with a rotating polishing block, but it is difficult to polish some lenses with curved edges completely, especially for some round lenses, which have the problem of poor polishing effect and are easy to scratch the main body of the lens during the polishing process.
