Technical Field
The invention belongs to the field of machinery, and particularly relates to a method and a device for producing U-shaped glass with an online film coating function.
Background
The existing U-shaped coated glass is usually made by using common U-shaped glass, U-shaped toughened float glass or U-shaped rolled patterned glass, cleaning and then feeding into a coating machine, and coating a film system consisting of titanium, silicon, tin, nickel, chromium, silver and compounds thereof on the U surface of the U-shaped glass in a vacuum chamber of the coating machine according to the known technology to form U-shaped LOW-E LOW-emissivity coated glass or heat reflection coated glass. The realization method of the prior patent comprises the following steps: the common U-shaped glass is plated with a LOW-E LOW-radiation film system or a heat reflection film by the existing production method and device for magnetron sputtering hot bending glass. In short, this is an "off-line coating" technique, i.e., the inner surface of the U-shaped glass is coated again after the U-shaped glass is completely manufactured.
The off-line coated U-shaped glass has the following defects: 1) the size of the glass process is limited by the size of the vacuum chamber of the apparatus. Because the U-shaped glass has a self-supporting function, the U-shaped glass is required to be more than 8 meters in many application occasions, and the processing requirements of the ultra-long U-shaped glass cannot be met by a common off-line coating vacuum chamber. 2) The off-line coated U-shaped glass is firstly toughened and then coated. After coating, the film can not be thermally treated, otherwise the film can be damaged.
