With the continuous improvement of living standard of people, electronic products such as mobile phones, tablet computers, cameras, notebook computers and the like have become popular gradually. Most cover plates of electronic products are made of plastics or metals at the present stage, and the single style cannot meet the pursuit of people on fashion and individuality at present. The plastic cover plate and the metal cover plate have various defects, wherein the plastic cover plate has serious homogenization and is easy to fade after being used for a long time, so that the use appearance is influenced; although the metal cover plate has beautiful appearance, the metal has the defects of strong interference to signals, easy scratching and the like. In order to avoid interference of metal on signals, most metal cover plate products have to adopt a three-section design, and the design is complex, so that the unity and the aesthetic feeling of the metal cover plate products are influenced.
With the development of electronic products such as smart phones, the styles and materials of the products are gradually improved, the quality of the materials is also gradually improved, and the glass cover plate has the advantages of no interference to signals, high hardness after tempering and the like and is popular with a large number of consumers. In recent years, the glass cover plate with the frosted effect is gradually the first choice of consumers due to the advantages of beautiful vision, difficult appearance of fingerprints in use and the like. The gradual change effect makes the style of the cover plate more novel, and presents different effects such as gradual change colors, patterns and the like. Therefore, if the two are fused, the ground glass cover plate with the gradual change effect is manufactured, the aesthetic feeling of the product shell can be further increased, and diversified effects such as colors, patterns, vision and the like are presented.
CN107009275A discloses a method for processing frosted glass with gradual change effect, which comprises the following steps: step 10: the method comprises the following steps of (1) carrying out film coating protection on one surface of a glass substrate, which does not need to be frosted; step 20: carrying out gradual change sand blasting treatment on the glass substrate subjected to film covering protection; step 30: and cleaning the glass substrate subjected to sand blasting to obtain the frosted glass with the gradual change effect. The step 20 specifically comprises the following sub-steps: step 21 a: starting the spray gun, and controlling the grain diameter of the sand grains sprayed out by the spray gun to increase or decrease gradually along with the time; step 22 a: and controlling the spray gun to move from one end of the glass substrate to the other end of the glass substrate. The manufacturing process of the CN106994438A gradual change frosted cover plate can realize the frosted effect of the substrate 1 in a mode of spraying the particles 2 on the substrate, and realize the gradual change effect by changing the diameter, the distribution state and the accumulation thickness of the particles, so that the cover plate finally has the gradual change frosted effect. CN107116956A discloses a manufacturing process of a gradient frosted cover plate, which comprises: cleaning, making a gradually-changed frosting layer and tempering. Firstly, cleaning glass; a sand blasting process is adopted, a frosted layer is manufactured on the surface of the glass, and the gradual change effect of the frosted layer is realized by changing the distance between the spray head and the glass; and finally, tempering the glass to obtain the cover plate with the gradually-changed frosted effect. In actual operation, the spray heads can move along the same direction to obtain a frosted layer with a gradient effect in a single direction; and the nozzle can also move towards two directions to obtain a frosting layer with a bidirectional gradual change effect.
In the manufacture of the gradual change frosted cover plate of the patent literature, only one spray head is used, so that the gradual change frosting effect is realized, the accurate control of the spray head is difficult, and the yield of the product is not high.
Therefore, how to manufacture the frosted glass cover plate with the gradual change effect is a difficult problem to be solved urgently in the field at the present stage.
