Problems solved by technology

The existing diaphragm texture is realized by transfer printing, which is limited by the characteristics of glue, such as flexibility and viscosity. The texture formed by transfer printing is relatively simple, and the common texture is D4 texture.

preparation example Construction

[0061] A preparation method of a textured mold, comprising the following steps:

[0062] providing a mold, the mold comprising a punch or die;

[0063] Perform multiple rounds of laser processing on the mold according to a preset program to form a first texture on the punch or die of the mold;

[0064] The process parameters of each round of the first laser treatment independently include:

[0065] The laser power is 5w-8w, the scanning speed is 400mm / s-600mm / s, and the number of scans is 25-35 times;

[0066] The laser beam routes of the first laser treatment in different rounds are not repeated, and the minimum distance between the laser beams of the first laser treatment in different rounds is 1 mm-7 mm.

[0067] Compared with machining, the use of laser engraving to form texture on the mold has the advantage of high precision, fine texture lines, and controllable line spacing, which can greatly reduce the defects of texture line collapse. (2) The laser is used for textu...

Embodiment 1

[0124] Example 1

[0125] The inner cavity of the graphite mold is cleaned with an alcohol-free cloth and an air gun to obtain a clean inner cavity graphite mold, and the graphite mold is subjected to the first laser engraving with a laser, and a vertical stripe texture 3D texture pattern is formed in the graphite mold concave mold. The power of the laser is 8w, the scanning speed of the laser is 550mm / s, and the number of scans is 28. The minimum distance between the laser beams processed by the first laser in different rounds is the distance between two adjacent vertical stripes. The distance is 3mm. It is cleaned, polished and finely ground to make the inner cavity of the mold clean, and the graphite mold with vertical stripe texture in the inner cavity is obtained, see figure 1 . The 0.7mm2D glass substrate was placed in a textured graphite mold for hot bending with 3 rounds, each molding temperature was 710°C, the molding time was 90s, and the pressure was 0.5MPa, to ob...

Embodiment 2

[0127] Example 2

[0128] The inner cavity of the graphite mold is cleaned with an alcohol-free cloth and an air gun to obtain a clean inner cavity graphite mold. The graphite mold is first laser engraved with a laser, and a vertical stripe 3D texture pattern is formed in the graphite mold concave mold. The power of the laser is 5w, the scanning speed of the laser is 600mm / s, the number of scans is 30 times, and the distance between two adjacent striped textures is 2.5mm. For the arc edge of the mold, multi-point linear fitting can be used according to the mold drawing, so that the curve presented by each focus of the laser action on the arc edge after fitting is consistent with the mold arc edge drawing, so as to achieve the second laser on the arc edge to form textures The effect of , the laser beam route of the second laser treatment in different rounds is not repeated, and the minimum distance between the laser beams of the second laser treatment in different rounds is 2mm...

Abstract

The invention relates to a texture mold, 3D glass with a texture surface and a preparation method and application of the 3D glass. The preparation method of the texture mold comprises the following steps: providing a mold comprising a male mold or a female mold; multiple rounds of first laser treatment are conducted on the mold according to a preset program, and first textures are formed on a male mold or a female mold of the mold; the parameters of each round of first laser treatment are respectively and independently as follows: the laser power is 5w-8w, the scanning speed is 400mm / s-600mm / s, and the scanning times is 25-35; the laser beam paths of different rounds of first laser treatment are not repeated, and the minimum distance between the laser beams of different rounds of first laser treatment is 1mm-7mm. The texture mold manufactured through the method is fine in texture line, controllable in line distance and few in edge breakage defect of the texture line, and the requirement for complex texture patterns can be met. The hot bending forming method can be used for hot bending forming to prepare 3D glass which is fine and diversified in texture line, controllable in line distance and provided with a texture surface.

Description

technical field [0001] The present invention relates to the technical field of 3D glass, in particular to a textured mold and a 3D glass with a textured surface and a preparation method and application thereof. Background technique [0002] Glass materials are expected to become the main trend in the smart terminal industry due to their high light transmittance, high hardness, high wear resistance, good thermal and chemical stability, and low electromagnetic wave transmission attenuation performance. [0003] At present, the appearance of mobile phones is valued by more and more consumers. In the eyes of many users, the appearance design of the product has exceeded the hardware configuration, and has become the first factor for consumers to buy a new mobile phone. Consumers pursue more The look and feel of the phone. [0004] The use of glass material as the mobile phone body has gradually become the mainstream design. The existing textured glass cover processing methods ge...
