Abstract

The invention discloses an ultra-thin glass coating process which is characterized by comprising the following steps: cutting a PET film according to the size of a glass bottom plate by utilizing a laser cutting machine, and forming an empty groove in the PET film according to the overall dimension of ultrathin glass; fixing an UV viscosity-reducing adhesive layer to a glass bottom plate, and attaching the PET film with the empty groove to the surface of the attached UV viscosity-reducing adhesive layer; finally, pasting the ultrathin glass into the empty groove; carrying out coating operation; and after the film layer on the surface of the ultrathin glass is dried, stripping the film-coated ultrathin glass. The ultrathin glass coating process can effectively solve the problems that the ultrathin glass is easy to damage after coating fixation and stripping after coating, can effectively avoid the problem of liquid seepage at the back of the coating edge position of the ultrathin glass in the coating process, and can also effectively improve the smoothness of the edge of a coated product. And meanwhile, the process scheme can greatly reduce the production cost and the process difficulty, can improve the yield and the production efficiency, and has relatively high practicability and relatively good application prospects.

Description

technical field

[0001] The invention belongs to the technical field of touch screens, and more specifically relates to an ultra-thin glass coating process. Background technique

[0002] With the market's demand for the convenience, thinness, and high-end of mobile phones and other electronic products, electronic products related to folding screens continue to appear. However, the current electronic products related to folding screens are still immature. In actual use, the screen is prone to creases, cracks in the bending area, and black screens. This has set off a wave of research on folding screens. For the technical difficulties of folding screen research, the material of the screen cover is an extremely important part. Ultra-thin glass (UTG), which is currently appearing in the market, has attracted much attention because of its good properties such as flexibility and bending, light transmission, and wear resistance. However, ultra-thin glass also has its own defects an...

Embodiment Construction

[0019] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0020] The present invention is a method for optimizing the coating process of fixed small-sized, multi-standard ultra-thin glass, mainly aiming at small-sized, ultra-thin glass of different specifications and models, and proposes a PET film 4, UV The solution of the adhesion-reducing adhesive layer 2, the glass base plate 1 and the ultra-thin glass 3 is mainly to solve the problems that the coating of the ultra-thin glass 3 is difficult to fix and easy to be peeled off after coating.

[0021] The ultra-thin glass coating process of the present invention mainly includes four parts: a glass bottom plate 1 , a UV adhesive-reducing layer 2 , a PET film 4 with empty grooves, and an ultra-thin glass 3 . It can be applied to ultra-thin glass of small size and different specifications, such as ultra-t...
