Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, changes the situation of existing solid color, makes its color variation, has metal-like again simultaneously, meets the demand of modern people to personalization.
The manufacturing process of a kind of colorful display screen glasses lens of the present invention may further comprise the steps:
(1) at blank surface plating SiO
2Replace the colored rete that superposes with other compounds;
(2) remove unwanted coatings with the method for engraving, also can carve out needed figure or character;
(3) with the pattern that designs and color printing on product coatings surface.
Other compounds of the present invention are TiO
2Or MgF
2Or ZrO
2Or TiN or ZrN or Ti
3O
5Described blank is clear glass thin slice or suprasil thin slice or transparent Al
2O
3Thin slice or transparent plastic sheet; The present invention adopts vacuum coating; Adopt laser engraving.
The invention has the beneficial effects as follows and changed the situation of solid color in the past, make product have abundant colors, and its color is not to form by toner or the simple toning of pigment, but allow the light of rete refraction or reflection different wave length produce by optical principle, so its color fades never.And the illusion-colour effect that changes irregularly and different colours in different angles.Its outward appearance seems gorgeous, has the outward appearance and the texture of jewel, and is graceful especially attractive in appearance.
The present invention can be used for the display screen eyeglass and the shell of electronic products such as mobile phone, MP3, MP4, Personal Handyphone System, palm PC, notebook computer, digital camera, video camera, household electrical appliance, telepilot.
Embodiment
The manufacturing process that technical solution problem of the present invention is adopted comprises following step:
(1) the following material a of the optional usefulness of display screen eyeglass of the present invention, clear glass thin slice b, suprasil thin slice c, transparent Al
2O
3Thin slice etc.-------------------stiffened---cleaning---drying is made the blank of required size specification to plain grinding to bevelling to Tuo rosin on the car limit to paste rosin by following operation, as to open material.Transparent plastic material such as PC, PET, PMMA etc. are by precision die, and injection moulding processes, and also can buy molded good plastic tab up to specification on market.Make the blank of required specification by the precision engraving, and its outside surface (single face) is carried out stiffened handle.
(2) pasting protective film adopts resistant to elevated temperatures plastic sheeting, is die-cut into needed size by designing requirement, is attached to the blank surface then.Can play the effect of anti-scratch and resistance plating, when promptly preventing the vacuum plating, being plated in does not need the surface of electroplating.
(3) vacuum plating plates the rete such as the SiO of various colors at the blank surface vacuum

2And MgF
2Alternately the colour film series of strata of stack are listed as or ZrO
2And SiO
2Replace colour film series of strata row or the TiN and the SiO of stack
2Replace colour film series of strata row or the ZrN and the SiO of stack
2Alternately the colour film series of strata of stack are listed as or Ti
3O
5And SiO
2Alternately the colour film series of strata of stack are listed as or the like.
(4) laser engraving is removed unwanted vacuum plating rete with the method for laser engraving, also can carve out needed pattern or character.
(5) printing, according to the pattern that designs and color printing at product vacuum plating film surface.
(6) pasting protective film, at the product surface pasting protective film with anti-scratch.
Be described further with regard to vacuum plating below: the film system of electroplating various colours at surface vacuum that product requires.At first the requirement of product appearance color and factors such as base material incident material and outgoing material are designed film system according to the client, and the refractive index of analyzing film system, transmitance, PSI density, thickness, and wavelength or the like, design corresponding technological parameter.By the examination plating, revise and regulate again, plate out corresponding color.The present invention is with Ti
3O
