Technical Field

The invention relates to the technical field of film thickness detection of coated glass, in particular to an optical detection system and a detection method for defects of a coated glass film.

Background

Coated glass (refictiveglass) is also known as reflective glass. The coated glass is prepared by coating one or more layers of metal, alloy or metal compound films on the surface of glass to change the optical performance of the glass and meet certain specific requirements. The coated glass can be divided into the following types according to different characteristics of products: heat reflective glass, Low emissivity glass (Low-E), conductive film glass, and the like. The heat reflection glass is generally formed by plating one or more layers of thin films composed of metals such as chromium, titanium or stainless steel or compounds thereof on the surface of the glass, so that the product has rich colors, has proper transmissivity to visible light, higher reflectivity to infrared rays and higher absorptivity to ultraviolet rays, is also called as sunlight control glass and is mainly used for buildings and glass curtain walls; the low-radiation glass is a film system formed by plating a plurality of layers of metals such as silver, copper or tin or compounds thereof on the surface of the glass, has higher transmissivity to visible light and higher reflectivity to infrared rays, has good heat-insulating property, is mainly used for buildings, automobiles, ships and other vehicles, and is generally made into hollow glass for use due to the poor strength of the film layer; the conductive film glass is formed by coating a conductive film such as indium tin oxide on the surface of glass, and can be used for heating, defrosting and defogging of glass, and can be used for liquid crystal display screens and the like. The production methods of the coated glass are various, and mainly comprise a vacuum magnetron sputtering method, a vacuum evaporation method, a chemical vapor deposition method, a sol-gel method and the like. The magnetron sputtering coated glass can be designed and manufactured into a multilayer complex film system by utilizing a magnetron sputtering technology, can be coated with various colors on a white glass substrate, has better corrosion resistance and wear resistance of a film layer, and is one of the most produced and used products. The variety and quality of vacuum evaporation coated glass have certain differences compared with magnetron sputtering coated glass, and the vacuum evaporation coated glass is gradually replaced by a vacuum sputtering method. The chemical vapor deposition method is to introduce reaction gas into float glass production line to decompose on the surface of glowing glass and to deposit on the surface of glass uniformly to form coated glass. The method has the characteristics of less equipment investment, easy regulation, low product cost, good chemical stability, and capability of carrying out hot processing, and is one of the production methods with the most development prospects. The sol-gel method for producing the coated glass has simple process and good stability, and has the defects of high light transmittance and poor decoration of the product.

In the prior art, generally, the thickness of the coated glass is detected manually, the automatic detection of the coating thickness is not realized by a set of complete equipment, the manual detection is time-consuming and labor-consuming, and the detection efficiency is greatly reduced.
