G. cleaning with pure water to remove redundant UV glue;
H. adopting laser to sweep UV glue above the hydrolysis glue;
I. taking out the front cover plate, soaking with pure water of 60 ~ 90 deg.C to remove the hydrolyzed glue layer, washing with pure water for 2 ~ 3 times, and air drying.
The method of the invention also comprises the following steps: J. carrying out non-conducting vacuum coating treatment; K. the color requirement of the product is finished by printing matched ink; and L, cleaning and pasting a protective film.
In the invention, the coating thickness of the non-conductive vacuum coating is less than 1um, the coating thickness of the UV glue is controlled to be 4um ~ 8um, and the thickness of the ink layer printed by the ink is controlled to be within 6 um.
In the invention, the touch screen is a mobile phone touch screen or a tablet computer touch screen.
Compared with the prior art, the method for achieving the decoration effect of the front cover plate of the touch screen by using the UV imprinting technology has the technical effects that: 1. coating UV glue and then embossing by using a fine printing plate, so that the product can generate a fine three-dimensional texture effect on visual impression; 2. the non-conductive vacuum coating treatment can further enhance the stereoscopic visual effect on the appearance of the product, and the color of the appearance of the product can be relatively adjusted by adopting ink printing (such as silk-screen printing or spraying), so that brand-new stereoscopic visual impression is further achieved; 3. the thickness is thin, the total thickness of the UV imprinting layer including the subsequent electric coating layer and the printing layer can be controlled within 15 mu m, and therefore, the rear-section full-lamination screen pasting process cannot be influenced; 4. the texture type can be designed according to the requirement of visual effect, such as wire drawing, CD texture, metal imitation texture, mosaic and water drop texture, etc.; 5. the adhesive force of the UV impressing layer and the glass layer is superior to that of any intermediate adhesive material used in the existing film pasting, the UV impressing layer is wear-resistant and scratch-resistant, and the service life of the product can be prolonged.

The detailed description is to be read in connection with the preferred embodiments illustrated in the appended drawings.
The invention discloses a method for achieving a decorative effect of a front cover plate of a touch screen by using a UV (ultraviolet) stamping technology, which comprises the following steps as shown in figures 1 and 2:
A. manufacturing a fine texture impression printing plate and a matched clamp;
B. carrying out antifouling treatment on the front cover plate, and placing the front cover plate in a mould which is customized in advance;
C. coating a hydrolysis glue on the back of the visible area of the front cover plate;
D. coating UV glue on the back of the front cover plate in a full-page mode, wherein the coating thickness is controlled to be 2 um ~ 20 um;
E. the clamp of the imprinting printing plate and the mold where the target object is located are aligned and positioned, fine texture imprinting is carried out on the UV coating according to the stroke, and the imprinting depth is stably controlled in the imprinting process;
