Abstract
The present invention relates to a double-color spraying technology for appearance products such as mobile phone shells and flat computer shells, and especially relates to a digital product shell double-color spraying technology. Electroplating is carried out after colored paint spraying, and an ultraviolet laser etching technology is then adopted to melt partial undesired electroplated color, thus to simultaneously display a sprayed color and the electroplated color. With adoption of the three-dimensional laser etching technology, the shape of a product can be converted as required, laser etching is carried out on the product once, the visual effects of the product are greatly raised, breaking of the product is reduced, and the production efficiency is raised.
Description
Technical field
The present invention relates to the double-colored spraying technology of the looking products such as a kind of mobile phone shell, dull and stereotyped casing, particularly relate to the double-colored spraying technology of a kind of digital product shell.
Background technology
Because the performance and needs attractive in appearance considering outward appearance sprays in digital product shell is produced, now along with the raising of the continuous progress of production technology and the aesthetic standard of people, client to appearance requirement also along with raising, phone housing after existing spraying technology spraying can only show a color, the mobile phone shell of spraying or plating can only show spraying look and plating look, can not embody two colors on a product simultaneously, be not enough to meet client and consumer demand.
Chinese patent (CN201210103481.X) discloses a kind of surface treatment stereoscopic three-dimensional radium carver skill, provide a kind of surface treatment stereoscopic three-dimensional radium carver skill with 3-D effect, but do not solve in general radium carving and can only carry out radium carving to a face and general shell face can only show the technical problem of a color, there is certain limitation.
Summary of the invention
The technical problem that the present invention solves is that the phone housing after the spraying of existing spraying technology can only show a color, and the mobile phone shell of spraying or plating can only show spraying look and plating look, can not embody on a product to two colors simultaneously; And radium carving can only be carried out to a face in general radium carving, need dismounting product and again debug radium carving machine just can.For the problems referred to above, the present invention by electroplating after color spray paint again, then is melted unwanted for part plating look the technological means fallen by ultraviolet radium technology for fast carving on and is shown spraying look and plating look simultaneously; The three-dimensional radium technology for fast carving on adopted, the basis of former radium carving machine increases the syncmotor that the syncmotor of automatic focusing and product rotate automatically, after the one side of product has been carved, according to the syncmotor of the parameter product of setting and the syncmotor synchronous operation of adjustment laser height, laser instrument camera lens is made to remain consistent with by the focal length of carving product.Can change according to the shape of product needed, disposable engraving is carried out to product, greatly increase the visual effect of product, and reduce disassembling of product, enhance productivity.
