Electronic product shell, electronic product cover spraying method

Abstract

The present disclosure relates to a spraying method for an electronic product casing and an electronic product cover, the spraying method comprising: fixing a spraying device; conveying the electronic product cover below the spraying device along the length direction of the electronic product cover; and using The spraying equipment sprays the upper surface of the conveyed electronic product cover, wherein, in the step of using the spraying equipment to spray the upper surface of the conveyed electronic product cover, the spraying The effective spraying width of the equipment is greater than the width of the electronic product cover. In this way, the spraying equipment is fixed, and the electronic product cover plate is sent to the bottom of the spraying equipment for spraying operation, which can realize assembly line and batch operation, and improve the spraying efficiency. The effective spraying width of the spraying equipment is much larger than that of the electronic product cover plate. Width, the effective area of ​​ink atomization is all coated on the cover plate of electronic products, realizing full-coverage spraying on the cover plate of electronic products.

Description

technical field [0001] The present disclosure relates to the field of production and manufacturing of electronic products, and in particular, to a method for spraying electronic product casings and electronic product cover plates. Background technique [0002] During the manufacturing process of electronic products, such as mobile phones and tablets, etc., cover plates are usually installed to protect the electronic components inside. Take the glass cover on the mobile phone shell as an example. Since the glass cover is made of transparent material, in order to prevent the human eye from seeing the electronic components inside the mobile phone through the glass cover, the surface of the glass cover will be sprayed to protect the glass cover. board and enhance the aesthetics of the phone. [0003] In the existing spraying method, the glass cover plate is fixed on the spraying fixture, and the spray gun sprays the surface of the glass cover plate fixed on the fixture along th...

AI Technical Summary

Problems solved by technology

[0003] In the existing spraying method, the glass cover plate is fixed on the spraying fixture, and the spray gun sprays the surface of the glass cover plate fixed on the fixture along the X and Y travel paths. However, when the ink is atomized, the spray gun itself is still Due to the speed of movement, it is very easy to cause flying oil, and it is necessary to increase the repair process in the later stage, which is time-consuming and laborious, and is easy to cause defects such as scratches, light transmission, dirt, and gaps; the atomization of the spray gun ink cannot fully cover the upper surface of the glass cover, resulting in The glass cover plate after spraying is prone to defects such as edge penetration; in addition, the film thickness error on the glass cover plate after painting is relatively large, which cannot meet the industry standard. The spraying efficiency of the existing spraying method is low, the utilization rate of ink is low, and it cannot Realize the assembly line and batch spraying of glass cover plate
