Embodiment 1

[0080] The raw glass in this embodiment is Corning GG7 type glass.

[0081] The processing method of curved surface glass in the present embodiment is:

[0082] S01: Cutting the raw glass to obtain cutting glass. The thickness of the cut glass is 0.6 mm, the length of the cut glass is 15 mm larger than the length of the effective area, and the width of the cut glass is 15 μm larger than the width of the effective area.

[0083] S02: Process the hot bending mold so that the length of the molding cavity of the mold is 10 μm longer than the length of the cutting glass. The width of the forming cavity of the mold is equal to the width of the opening glass.

[0084] S03: The first CNC treatment, the cutting glass is subjected to the first CNC treatment, and the removal amount is 15 μm.

[0085] S04: Cutting process, cutting preset depths at both ends of the cut glass in the longitudinal direction, controlling the preset depth to be smaller than the thickness of the cut glass, to...

Embodiment 2～ Embodiment 5

[0097] Compared with Example 1, the difference between Example 2 to Example 5 lies in the thickness of the cut glass, the difference between the length of the cut glass and the length of the effective area, the length of the molding cavity of the mold and the length of the cut glass Differentials, cutting pressures, preset depths of cut vary. It should be noted that the length of the cut glass is longer than the length of the effective area, and the length of the molding cavity of the mold is longer than the length of the cut glass.

[0098] In Example 1 to Example 5 and Comparative Example 1 to Comparative Example 3, the thickness of the cut glass, the difference between the length of the cut glass and the length of the effective area, the length difference between the length of the molding cavity of the mold and the length of the cut glass , cutting pressure, and preset depth of cutting are shown in Table 1.

Abstract

The invention relates to a curved glass processing method. The processing method includes the following steps: cutting the raw glass to obtain the cutting glass. The preset depths are cut at both ends of the cut glass in the long direction, and the preset depth is controlled to be less than the thickness of the cut glass to obtain cut glass. The cutting position divides the cut glass into effective areas and invalid areas, and controls the effective area. The length is equal to the length of the target glass. The cut glass is subjected to hot bending treatment in the mold to obtain hot bent glass. The hot bending glass is separated along the cutting position to separate the effective area from the invalid area. With this processing method, the cut glass will be cut before the hot bending treatment, and the appropriately increased pressure at the four corners will be fully dispersed in the invalid area during the hot bending treatment. The resulting target curved glass does not have heavy stamps at the four corners, which is beneficial to improving the yield of the curved glass.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing, in particular to a curved glass processing method. Background technique [0002] With the continuous improvement of production technology, more and more electronic products will use curved glass. Curved glass brings a more diverse appearance to electronic products and provides consumers with more choices. However, because curved glass is very different from flat glass in structure, the curved glass obtained by traditional processing methods is prone to severe stamping at the four corners. Contents of the invention [0003] Based on this, it is necessary to provide a curved glass processing method, which can effectively reduce the stamping degree at the four corners of the curved glass and improve the yield of the curved glass. [0004] In order to solve the above technical problems, technical method of the present invention is: [0005] An object of the present invention is to pr...
