Description

technical field [0001] The invention relates to the technical field of glass coating structures, in particular to a conveying and rotating device for double-sided glass coating. Background technique [0002] Coated glass is also called reflective glass. Coated glass is coated with one or more layers of metal, alloy or metal compound films on the surface of the glass to change the optical properties of the glass to meet certain requirements. Coated glass can be divided into the following categories according to the different characteristics of the product: heat reflective glass, low-emissivity glass (Low-E), conductive film glass, etc. [0003] There are many production methods of coated glass, mainly vacuum magnetron sputtering method, vacuum evaporation method, chemical vapor deposition method and sol-gel method. Magnetron sputtering coating glass can design and manufacture multi-layer complex film system by using magnetron sputtering technology, and can plate a variety o...

AI Technical Summary

Problems solved by technology

The process of producing coated glass by sol-gel method is simple and stable, but the disadvantage is that the light transmittance of the product is too high and the decoration is poor

[0004] The current coating equipment adopts the method of double-sided coating. The equipment is divided into front and back sides. Target materials are installed on both sides of the equipment, and the substrate rack loaded with glass is also divided into front and back sides. The heater is installed in the center of the vacuum chamber. One integral type, suspended in the air by means of hoisting, during the coating process, glass is loaded on the front and back of the substrate holder, and the substrate holder with glass is walking in the vacuum chamber during coating, and the front and back of the substrate holder are respectively located in the middle of the heating Both sides of the device are coated by magnetron sputtering through the target area. This method can only coat one side of the glass at a time. The glass is cleaned again, and then coated in the vacuum chamber again, that is, the coating process has to be repeated twice to complete, which not only wastes manpower, financial resources, low output, and the yield rate of the glass will be greatly reduced after multiple turnovers.

[0005] The structural design of the entire vacuum chamber can only prepare the film layer on one side of the glass substrate at a time. If the film layer needs to be prepared on both surfaces of the glass substrate, the existing technology can only prepare the film layer on one surface of the glass substrate Finally, repeat the first film coating process on the glass substrate to complete the preparation of the second film layer. This process will affect the performance of the first film layer during the second film preparation process, and Due to the drop in yield rate caused by secondary coating, the overall production cost is high
