Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of processing of solar glasses, in particular to a production process of anti-scattering reflective POL glasses. BACKGROUND

[0002] POL is also called polarizer, and the full name is polarized light sheet. The imaging of liquid crystal display must rely on polarized light. All liquid crystals have two polarized light sheets closely attached to the liquid crystal glass, forming a liquid crystal sheet with a total thickness of about 1mm. If any one polarized light sheet is missing, the liquid crystal sheet cannot display images. 3D glasses use this principle, so they can also be applied to the production and processing of solar glasses.

[0003] In the prior art, the solar glasses need to be polished during production and processing. In the existing production process, the polishing operation is mainly performed by a dedicated polishing machine. The polishing machine can polish the outside of the fixed glasses through the polishing assembly assembled inside. The polishing assembly mainly consists of an abrasive stone and a turntable capable of driving the abrasive stone to rotate. As the working time increases, the abrasive stone will gradually wear out and need to be replaced. However, in fact, only the abrasive stone is worn out, and the disassembly and repair frequency of the turntable is much lower than the replacement frequency of the abrasive stone. In the existing process, when replacing the abrasive stone, the turntable is taken out together with the worn-out abrasive stone. The turntable and the abrasive stone are connected and fixed by relying on a bolt fixing member during installation, which makes the disassembly, replacement and installation of the polishing assembly more complicated, affecting the production efficiency of the entire process. Therefore, the present application provides a production process of anti-scattering reflective POL glasses to meet the needs. SUMMARY
