Embodiment Construction

[0021] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0022] The post-processing process of the back cover of the highlight mobile phone is processed through the following steps:

[0023] 1. The outer surface of the back cover of the mobile phone to be processed is ground and polished to obtain a polished part. The grinding process adopts the traditional aluminum mobile phone back cover grinding process. After the grinding is completed, the fine polishing process is performed. After inspection, the polished parts can be obtained after passing the inspection;

[0024] 2. Spray a layer of CNC masking ink on the outer surface of the polishing part in step 1 to obtain the part to be treated with side holes. The CNC masking ink is sprayed on the outer surface of the polishing part by UV spraying. The CNC masking ink is excellent The thickness is 0.004~0.0045mm;

Abstract

The invention discloses an aftertreatment processing technology of a highlight cell phone rear cover. The aftertreatment processing technology comprises the steps of grinding and polishing the outer surface of the to-be-treated cell phone rear cover; spraying CNC shielding paint to the outer surface of a polishing part; then, processing a side hole; carrying out polishing to remove burrs on the hole edge of the side hole with abrasive paper; after polishing, processing and treating highlight strips, so as to obtain a semi-finished product; removing the CNC shielding paint on the surface; and finally, carrying out surface oxidation treatment, so as to complete aftertreatment processing of the cell phone rear cover. Compared with the prior art, the aftertreatment processing technology has the advantages that the side hole is not chambered due to burr removing of the side hole through the aftertreatment processing technology, only one-time surface oxidation treatment is carried out duringthe entire process, the integral color of the outer surface of the cell phone rear cover always maintains uniform, a highlight vision effect is achieved, and the problems that white lines are generated during traditional cell phone rear cover aftertreatment processing and the defective rate is 5% are solved.

Description

Technical field [0001] The invention relates to the field of manufacturing mobile phone accessories, in particular to a post-processing processing technology for the back cover of the mobile phone. Background technique [0002] Existing mobile phone back covers are classified into plastic, tempered glass, aluminum alloy, combination of plastic and tempered glass, or combination of plastic and aluminum alloy according to the material. Among them, the mobile phone back cover made of aluminum alloy has good hand feeling and high strength. Good brightness and other effects are popular among young people. The molding process of the existing aluminum mobile phone back cover molding process is: forging→CNC treatment→T treatment→NMT injection→CNC treatment→post-processing→laser carving→inspection and assembly→shipping. The post-processing includes grinding and polishing, Oxygen treatment, CNC machining side hole treatment, high-gloss band processing and di-oxygen treatment. In this post...
