Film pasting vacuum electroplating method

Abstract

The invention discloses a film pasting vacuum electroplating method, which comprises the following steps: a. processing incoming materials; b. pasting a film with a hollow pattern; c. removing an outer film and a middle film; d. coating a film, that is, performing sputtering coating processing of the product, taking out from a vacuum furnace, stripping away a bottom film to leave the electroplated pattern, performing primary examination, removing a hanging tool, detaching from a tool, performing secondary examination, covering the outer film; e. preparing before spraying; f. spraying, that is spraying UV paint with good glossiness on the product, then performing baking, UV curing, taking the product out, detaching from the spraying tool, and performing examination. The film pasting vacuum electroplating method of the invention does not form sawteeth at the pattern edge, and can be completed within a short period. In actual production, batch production of products with accurately-positioned pasted films is realized; the pasted film used in the invention does not release waste gas during vacuum coating, and has no blackening or yellowing phenomena of the film layer; and the method of the invention is a film-coating pattern-displaying scheme with rapid and mass production capability and beautiful patterns.

Description

technical field [0001] The invention belongs to the technical field of UV paint spraying and vacuum coating, and in particular relates to a film-sticking vacuum electroplating method. Background technique [0002] In the UV paint spraying and vacuum coating technology, a film of a special material is used to cover part of the coating area, so that the coating layer forms the desired pattern on the product. In the existing technology, laser engraving is often used to use light beams to knock out the positions other than the logo, but the use of laser engraving technology will inevitably form obvious jagged edges on the graphic edge, and second, it will take a long time. The time consumed by the laser engraving process It is several times that of the film sticking process. Some manufacturers in the prior art have also tried to adopt the film sticking process, but there are still some defects: one is that the film of suitable materials cannot be found, and the film releases m...

Problems solved by technology

In the existing technology, laser engraving is often used to use light beams to knock out the positions other than the logo, but the laser engraving process will inevitably form obvious sawtooth on the edge of the graphic, and the other is that it takes a long time. The time consumed by the laser engraving process It is several times that of the film sticking process

Some manufacturers in the prior art have also tried to adopt the film sticking process, but there are still some defects: one is that the film of suitable materials cannot be found, and the film releases miscellaneous gases during vacuum coating, which makes the film black and yellow; Appropriate film positioning technology and equipment, so that it is difficult to mass-produce film with precise position and paste it on the product
