Description

Stereo glass film processing method

This case relates to a method for manufacturing a glass film, and more particularly to a method for manufacturing a three-dimensional glass film.

It is generally desirable to form a pattern or pattern on the surface of the glass by additionally attaching a film having a pattern or pattern, and generally adhering the film to the surface of the glass in a manner that relies on human manipulation. However, this method is prone to incomplete or uneven placement. For example, in the process of pasting, the position or angle of the film placed on the glass is inaccurate, so that the lately pasted portion cannot completely cover the glass, or the gas is not completely discharged during the pasting process. There is a bubble between the film and the glass, which causes unevenness.

In addition, this way of directly bonding the film to the glass is less applicable to the non-flat glass. In detail, in the transition between different planes of the three-dimensional glass, the film may be incompletely attached, or the excess film must be adhered to each other and the like. Even if a ductile film can be used to slightly improve such conditions, on the other hand, the film cannot be uniformly applied to the stereoscopic glass, and the pattern or pattern on the film is deformed.

The invention discloses a method for manufacturing a three-dimensional glass film, comprising the steps of: providing a film having a body layer and an adhesive layer; placing a stereo glass and a film into a hot pressing mold, and setting the adhesive layer corresponding to the stereo glass Providing at least one of a predetermined temperature and a predetermined pressure to the film to pre-form the film; and hot pressing the mold to press the pre-formed film and the stereoscopic glass to adhere the film to the stereoscopic glass.
