Abstract

The invention discloses a coating jig, a vacuum coating device, a gradient color coating method, a preparation method for a decorative cover plate and a decorative cover plate. The coating fixture includes a first fixture and a second fixture; the first fixture includes a first molding die and a first fixture, the first molding mold is curved, and the outer curved surface of the first molding mold forms The first coating surface, the first fixture is used to fix the first forming mold on the coating umbrella and the first coating surface faces outward; the second clamp includes a second forming mold, a second fixing The second molding die is curved, the inner curved surface of the second molding die forms a second coating surface, and the second fixing part is used to fix the second molding die on the coating umbrella and The second coating faces outward. The vacuum coating device includes an evaporation coating machine and the coating fixture. The coating jig can effectively realize the gradual color coating of the plate, and has low cost.

Description

technical field [0001] The invention relates to a coating jig, a vacuum coating device, a gradient color coating method, a preparation method for a decorative cover plate and a decorative cover plate. Background technique [0002] The decoration of the protective cover on the surface of existing consumer electronic products tends to have a gradient color effect. The current color gradient effect is mostly achieved by inkjet or offset printing, and then vacuum coating is used on the basis of the gradient ink to achieve brightness. Boost to achieve the effect. Since both inkjet and offset printing use resin and toner for color matching, the particle size of the material itself is relatively large, and the visual graininess of the produced gradient color products is relatively strong and not fine enough, which affects the overall visual effect, and multiple printing and printing processes are added in the process. The offset printing process virtually prolongs the process flow...

Problems solved by technology

Since both inkjet and offset printing use resin and toner for color matching, the particle size of the material itself is relatively large, and the visual graininess of the produced gradient color products is relatively strong and not fine enough, which affects the overall visual effect, and multiple printing and printing processes are added in the process. The offset printing process virtually prolongs the process flow and increases the difficulty of product yield control

[0003] For special gradient color coating decoration, R series, P series, and M series products currently mainly use vacuum magnetron sputtering coating process to achieve color gradient effect by adjusting and correcting the size of the baffle to block the coating area. This kind of gradient color sputtering coating The method has great limitations. During the use process, it needs to adjust the correction version frequently and has strict requirements on the position, which makes it easy to have problems such as poor gradient effect. In addition, it also has great limitations in terms of operation, such as complicated target switching methods, The location of the target that can be installed is limited, and the difficulty of process switching is high. In addition, multiple printing and offset printing processes need to be added in the manufacturing process, which prolongs the process flow and increases the difficulty of product yield control, which virtually increases the processing cost.
