Embodiment 1

[0039] Firstly, the area to be cut 220 to be cut is planned on the strengthened glass 10, and then the cut adhesive film is directly attached to the surface of the strengthening layer 11 according to the distribution of the area to be cut 220 designed in advance, that is to say, using An adhesive film is attached to form the protection layer 22 including the area 220 to be cut.

Embodiment 2

[0041] completely coating the soluble material (or colloidal material) on the surface of the strengthening layer 12 of the strengthened glass 10, and then removing the soluble material according to the predetermined distribution of the region 220 to be cut, so that the distribution of the removed region of the soluble material Consistent with the distribution of the predetermined area 220 to be cut, the soluble material whose distribution has been designed is finally dried or baked to form the protective layer 22 including the area 220 to be cut.

Embodiment 3

[0043] A mask is covered on the surface of the strengthened layer 11 of the strengthened glass 10. This mask is designed according to the distribution of the predetermined region to be cut 220. The pattern of the mask is consistent with the distribution of the predetermined region to be cut 220, and then the The shield is placed together with the strengthened glass 10 in a chemical deposition machine, and a corrosion-resistant layer or an acid-resistant layer is plated on it, and then the shield is removed, that is to say, the patterned resist is formed by chemical deposition. In this way, the protective layer 22 including the area 220 to be cut is formed.

Abstract

The invention provides a method for cutting tempered glass. The tempered glass comprises a strengthening layer and a piece of inner glass. The strengthening layer is wrapped around the inner glass. The method for cutting tempered glass comprises following steps: (a) producing a protection layer on the surface of the strengthening layer of the tempered glass, wherein protection layer comprises an area to be cut and the area exposed to a part of the surface of the strengthening layer; (b) executing a etching process in order to remove the part of the strengthening layer corresponding to the area to be cut; and (c) cutting the inner glass along the area to be cut by using a mechanical force cutting manner. The method is capable of resolving problems of high processing cost and limited production capacity caused by cutting the tempered glass using a laser cutting method in the prior art.

Description

technical field [0001] The present invention relates to a cutting method of tempered glass, in particular to a cutting method of tempered glass using an etching process. Background technique [0002] Thin strengthened glass (such as: chemically, thermally or laminated strengthened glass) has excellent strength and damage resistance, and is widely used in consumer electronics products. Among various thin strengthened glasses, chemically strengthened glass or ion-exchanged glass is widely used in the display screen or touch screen of handheld devices (such as mobile phones, MP3 / MP4 players, and digital cameras, etc.) sheet or substrate and get attention. [0003] The production principle of ion-exchange glass is that the glass is soaked in a molten salt pool for ion exchange, and the alkene molecules on the surface of the glass will exchange with salt molecules, and a large number of salt ions press the glass surface to increase its strength. Because the ions in the inner la...
