Abstract
The invention provides a technology and a manufacturing method for achieving a window frame colored drawing pattern on touch panel cover glass (referred to as CG, the same below). The method comprises the following steps: a, varnish silkscreening: silkscreening a layer of varnish on the CG; b, drawing: performing mould pressing and solidification on UV glue (glue solidified by adopting UV light) to form a window frame pattern with a drawing effect on the CG; c, electroplating: electroplating 1-5 layers of color particles on a drawing texture; d, printing ink silkscreening: silkscreening 1-5 layers of printing ink in an upper frame area of an electroplated layer, so as to achieve the purpose of shading of the window frame; e, deplating: using deplating solution to etch electroplated particles in a visible area; f, printing ink silkscreening: silkscreening 1-5 layers of printing ink in a deplated CG frame area. The method can achieve a colored drawing effect on the CG directly, and compared with the traditional process that a pattern is formed on an organic thin film, and the organic thin film/glass is fitted with the CG, multiple procedures are eliminated, the product is thinned, the yield is improved, and the cost is saved.
Description
Technical field
The present invention relates to the touch technology field, particularly a kind of method that realizes the colored wire drawing pattern of form frame on the contact panel cover-plate glass.
Background technology
The application of cover-plate glass in electronic product is very extensive, but it is more difficult directly to form the very high wire drawing space pattern of precision on cover-plate glass.Be to fit with cover-plate glass (Cover Glass is called for short CG, and is lower same) again after making pattern on one deck organic film (Film) in the traditional handicraft of making space pattern on touch-type glass screen at present.Basic procedure is: wire drawing (on Film) → plating → ink for screen printing → take off plating → ink for screen printing → cutting → visual inspection → with white sheet CG applying → deaeration → visual inspection, and adopt above-mentioned flow process to make technique process more, cause cost to rise, production capacity descends, product thickness increases, and optical property descends.If directly form the wire drawing space pattern by modes such as mold pressings on cover-plate glass, be efficiently more convenient.
Summary of the invention
The object of the invention is to provides a kind of CG frame that can allow present colored wire-drawing effect for the deficiencies in the prior art, can reduce again a kind of method that realizes the colored wire drawing pattern of form frame on the contact panel cover-plate glass of manufacturing procedure, lifting yield, reduction product thickness.
The present invention is achieved through the following technical solutions above-mentioned purpose:
A kind of method that realizes the colored wire drawing pattern of form frame on the contact panel cover-plate glass comprises the steps:
A, silk-screen gloss oil: need part process silk-screen one deck gloss oil of silk-screen of colored wire drawing pattern on the cover-plate glass after cleaning, and toasted 10～30 minutes under 50 ℃～80 ℃, gloss oil is solidified;
B, wire drawing: have a side of gloss oil to form the form frame pattern layer of wire-drawing effect through mould pressing process method on cover-plate glass at the cover-plate glass silk-screen, then use energy at 300～1000mJ/cm
2UV illumination makes the UV adhesive curing, is formed with the form frame pattern layer of wire-drawing effect;
C, plating: electroplate 1～5 layer of colour developing particle layer on the UV glue-line that cleans back shroud glass;
D, ink for screen printing: electroplating 1～5 layer of ink lay of silk-screen on cover-plate glass after cleaning, baking;
E, take off plating: etch away with taking off the colour developing particle that plating solution electroplates the non-ink area of cover-plate glass;
F, ink for screen printing: on the cover-plate glass ink lay again 1～5 layer of printing ink of silk-screen make that ink area is light tight, the IR porose area when transmittance is 20%～30%, 650nm～940nm wavelength during at 380nm～650nm wavelength transmittance be 70%～90%.
The mould pressing process of described step b is as follows, an end in template is coated with the UV of delegation glue, the side cover that cover-plate glass was cleaned is on template, begin to be rolled into the other end of cover-plate glass from gluing with cylinder, glue is extended on whole glass surface, and be filled in the gap of template, form die plate pattern.
Described step a cover plate glass cleaning step is as follows: first utilize the not one side of coated surface of the described cover-plate glass of alcohol cleaning, then the organic substance residues of removing this side surface by the Ion Cleaning machine, its surperficial water droplet angle is down to below 15 °.
Use in described steps d and took off plating solution immersion cover-plate glass 45 seconds.
Adopt said method, this method can make UV glue form pattern by being connected on glass surface between gloss oil, makes operation reduce, and whole yield improves 5%～15%, and manpower/Material Cost descends 5%～10%, and the unit interval production capacity rises 5%～10%; And adopt product that this method obtains reduced one deck organic film material (prior art is after adhering to UV glue on the organic film one side and making pattern, the back side of organic film again with glass gluing), make whole optics penetrance increase by 1%～2%; The product integral thickness reduces, and is complementary with the wish of present mainstream technology " light, thin ".Whole optics penetrance increases, and makes the contact panel display screen more clear, only needs lower electric weight, the display effect that just can obtain to be equal to; Form the frame effect of colored wire drawing, satisfy present consumer to the diversified demand of product appearance.
