Problems solved by technology

[0008] In addition, GDM has no explosion-proof effect. If an explosion-proof film is attached, the thickness of the back cover of the mobile phone will be very large, which is not conducive to the production of ultra-thin mobile phones.

Embodiment Construction

[0035] refer to Figure 2 to Figure 5 The embodiment of the manufacturing method of the explosion-proof mobile phone glass back cover of the present invention will be further described.

[0036] A method for manufacturing an explosion-proof mobile phone glass back cover, comprising the following steps,

[0037] 1) Print pattern layer: Print pattern ink 6 that needs to be printed on the inner surface of glass back cover 2 by gravure pad printing device, and solidify pattern ink 6 to form a pattern layer;

[0038] 2) Printing the explosion-proof layer: the explosion-proof ink 7 is printed on the top of the pattern layer by a gravure pad printing device, and the explosion-proof ink 7 is cured.

[0039] Such as Figure 5 As shown, the gravure pad printing device adopted in this embodiment mainly includes a gravure cylinder 91, a pad printing cylinder 92 and a jig 93, wherein the pad printing cylinder 92 is a rubber roller, and the gravure cylinder is made according to the patter...

Abstract

The invention discloses a manufacturing method of an explosion-proof mobile phone glass back cover. The method comprises the following steps that 1) a pattern layer is printed, specifically, pattern ink used for printing patterns is printed to the inner side surface of the glass back cover through a gravure movable printing device, the pattern ink is solidified, and the pattern layer is formed; and 2) an explosion-proof layer is printed, specifically, explosion-proof ink is printed to the pattern layer through the gravure movable printing device, and the explosion-proof ink is solidified. According to the manufacturing method of the explosion-proof mobile phone glass back cover, the pattern ink printing precision is high, the thickness is small, the process flow is simplified, productionis more efficient, in addition, the explosion-proof layer is formed through direct ink printing, and the whole back cover is lighter and thinner.

Description

technical field [0001] The invention belongs to the field of mobile phone glass back covers, and more specifically relates to a method for manufacturing an explosion-proof mobile phone glass back cover and the glass back cover. Background technique [0002] GDF (GlassDecoFilm) is to print the texture or pattern on the glass explosion-proof film (usually PET material) by UV transfer, and then bond it to the glass back cover. [0003] The GDF process belongs to the decorative film process. It is widely used in the mobile phone back cover industry. Most of the models released by Huawei, oppo, vivo, and Xiaomi use this film process. The advantage is that if defective products are produced, the film can be torn off and returned to the factory for reprocessing. At the same time, because the decoration is processed on the diaphragm and then pasted, the degree of freedom in 3D surface design will be higher and more convenient. However, the film sticking also affects the light tran...
