Description

Technical Field

[0002] In the field of glass processing, glass coating is a key process that can give glass many excellent properties such as heat insulation, UV protection, and decoration. It is widely used in many fields such as construction, automobiles, and optical instruments. Common glass coating methods include vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition, and sol-gel. The sol-gel method is to coat the sol on the glass surface, and then convert it into gel through drying, heat treatment, and other processes to finally form a coating. The process is relatively simple and is therefore widely used. However, the traditional sol-gel method is only suitable for glass with strong integrity, and the solvent can completely cover the glass. For the surface of glass with holes, the solvent will pass through the holes when spraying, which will cause a waste of solvent on the one hand, and on the other hand, after the solvent passes through the holes, it will pollute the inside of the coating equipment, causing dirt or even corrosion, and reducing the service life of the equipment. Therefore, when coating glass with holes, it is necessary to locate the position of the holes. However, the current coating equipment does not have the function of directly locating the position and size of the holes, and can only simply cover the holes with a mask.
