Problems solved by technology

However, because it is almost impossible to use screen printing on concave and convex surfaces, there is no way to control the size of the printing area and the thickness of the ink, and some concave surfaces cannot be printed with ink at all.
[0003] With the updating of technology, a new window processing method for 2D / 3D products has been developed, specifically: first spray the ink layer on the 2D / 3D products, and use the laser to process the window with the ink side up, and burn it directly through the laser. The laser energy point falls on the surface of the product, so that the ablated ink cannot fall off, resulting in repeated ablation of the ink, which affects the effect of ink removal, and the light transmittance of the product can only reach 67%- 78%

Embodiment 1

[0027] see figure 1 , Workpiece 1 takes a 3D curved glass screen as an example, using laser to process the window includes the following steps:

[0028] The first step is to spray the ink layer 2 on the entire surface of the workpiece 1 to be processed (the window processing part and other parts are sprayed at the same time) (it is also possible to paste a protective film on part of the window area to be processed, and then spray ink on the entire surface Layer, the protective film can protect this area from being sprayed with ink layer, after tearing off the protective film, this area does not need to be processed by laser to remove ink, which reduces the area of ​​ink to be removed when laser processing the window);

[0029] The second step is to use a laser to remove the ink layer of the processing part of the window, specifically: the workpiece coated with the ink layer is placed on the fixture 4 with a groove, and the surface of the workpiece coated with the ink layer is ...

Embodiment 2- Embodiment 4

[0037] The difference between embodiment 2-embodiment 4 and embodiment 1 lies in the parameters in Table 1, and the others are the same.

[0038] The properties of the processed products obtained in Examples 2-Example 4 are shown in Table 2.

Abstract

The invention provides a method for processing a window through a laser. The method comprises the following steps that 1, an ink layer is sprayed on the window processing portion, on a to-be-processed surface, in a workpiece; 2, the ink layer on the window processing portion is removed through the laser, specifically, the workpiece which is sprayed with the ink layer is arranged on a clamp with a groove, and the to-be-processed surface of the workpiece and the inner wall surface of the groove are arranged oppositely; the ink layer is removed from the other surface which is opposite to the surface, provided with the ink layer, of the workpiece in an offset-focus processing mode through a laser machine, and the ink layer of the window processing portion on the workpiece is away from the inner wall of the groove by 5-50 mm; and the minimum distance between the laser focus and the surface of the workpiece is 3-5 mm. According to the method for processing the window through the laser, operation is convenient, the ink layer removing effect is good, and the light transmittance of ink-removed areas can be ensured.

Description

technical field [0001] The invention relates to the technical field of window processing, in particular to a method for window processing using a laser. Background technique [0002] With the development of processing and manufacturing industry, more and more 3D screen films are used on the window screens of some electronic products such as mobile phones and players. The appearance of the 3D screen film is more three-dimensional and more beautiful. However, since it is almost impossible to use screen printing on concave and convex surfaces, there is no way to control the size of the printing area and the thickness of the ink, and some concave surfaces cannot be printed with ink at all. [0003] With the updating of technology, a new window processing method for 2D / 3D products has been developed, specifically: first spray the ink layer on the 2D / 3D products, and use the laser to process the window with the ink side up, and burn it directly through the laser. The laser energ...
