Embodiment Construction

[0022] A method for surface treatment of a mobile phone shell will be further described in detail below in conjunction with the implementation and the accompanying drawings.

[0023] see figure 1 , the surface treatment method of mobile phone case of an embodiment, comprises the following steps:

[0024] S110. A double-layer clamp is provided, and two mobile phone casings are sequentially fixed on the double-layer clamp, and the distance between the upper and lower layers of the double-layer clamp is 8-10 cm.

[0025] Through the control of the distance between the upper and lower layers of the double-layer fixture, the coating coverage can be effectively controlled to ensure that the two mobile phone casings can be evenly coated.

[0026] In one embodiment, the double-layer clamp includes an upper cover, a middle cover and a lower cover. When fixing the mobile phone case, firstly engage a mobile phone case on the upper cover, then cover the middle cover, then fix a mobile p...

Abstract

The invention discloses a surface treatment method for mobile phone outer shells. The surface treatment method comprises the steps that a double-layer fixture is provided, and the two mobile phone outer shells are sequentially fixed to the double-layer fixture, wherein the interval of upper and lower layers of the double-layer fixture is 8 cm to 10 cm; the mobile phone outer shells are dedusted through a static ion fan; primer spraying is carried out on the mobile phone outer shells, wherein during primer spraying, the angle of a spray gun is 135 degrees to 180 degrees, spraying pressure is 1.8 Mpa to 2.0 Mpa, spraying distance is 8 cm to 10 cm, atomization pressure is 0.8 MPa to 1.0 Mpa, and oil pump pressure is 2.0 MPa to 2.1 MPa; vacuum coating is carried out on the mobile phone outer shells; middle paint spraying and surface paint spraying are carried out on the mobile phone outer shells; and the fixture is disassembled, and the mobile phone outer shells are subjected to complete inspection. According to the surface treatment method for the mobile phone outer shells, production efficiency can be effectively improved, and production cost can be effectively reduced.

Description

technical field [0001] The invention relates to the field of mobile phone shell processing, in particular to a method for treating the surface of a mobile phone shell. Background technique [0002] Mobile phones are one of the indispensable communication tools in our daily life. With the improvement of our living standards, the requirements for products are getting higher and higher. In order to make the mobile phone case more durable and beautiful, coating is required during the processing of the mobile phone case. With the popularity of smart phones, the market's recognition of the appearance of vacuum coating technology, and fierce market competition, the existing coating technology for mobile phone casings has increasingly shown limitations in terms of production efficiency, production costs, and equipment costs. Contents of the invention [0003] Based on this, it is necessary to provide a method for surface treatment of mobile phone shells with high production effic...
