A high-gloss process for charging interface shells of 3c products

Abstract

The invention discloses a 3C product charging connector shell highlight process. The 3C product charging connector shell highlight process comprises following steps that firstly, a CNC numerical control device is adopted to machine a charging connector shell; secondly, grinding stone I and the charging connector shell obtained in the first step are added into a grinding bucket of a rolling grinding machine according to the proportion to be subject to rolling grinding, and the ground charging connector shell is cleaned and dried; thirdly, the charging connector shell obtained in the second stepis subject to sand blasting treatment; fourthly, grinding stone II and the charging connector shell obtained in the third step are added into the grinding bucket of the rolling grinding machine according to the proportion to be ground. The 3C product charging connector shell highlight process has the good highlight effect, the product yield and the stability can be improved, the machining flow time can be shortened, manpower is saved, material losses are reduced, product production cost is reduced, and the product market competitiveness is improved.

Description

technical field [0001] The invention relates to the technical field of processing parts of 3C products, in particular to a high-gloss process for charging interface shells of 3C products. Background technique [0002] Such as figure 1 As shown, the charging interface of 3C products such as mobile phones and tablet computers is provided with a charging interface shell 1, and the inner side of the entrance of the charging interface shell 1 has a high-gloss surface 11, which is the key processing part of the high-gloss process. Usually, the width of the inlet of the charging interface case 1 is not more than 2mm. Figure 5 The processing flow of the charging interface case 1 in the prior art is schematically shown. In the prior art, the charging interface shell 1 with preset shape and size processed by CNC numerical control equipment is ground in a vibration grinder to remove residual burrs after CNC processing, and after cleaning and drying, sandblasting, cleaning and drying...

AI Technical Summary

Problems solved by technology

[0003] (1) During the vibration grinding process, the charging interface shell 1 is rubbed against the resin abrasive, and the burrs on the edge of the charging interface shell 1 are removed through friction, but the color of the charging interface shell 1 will change after grinding, which is dull and dull. uneven;

[0004] (2) In addition, if Figure 4 As shown, the edges and corners of the resin abrasive protrude into the inlet of the charging interface shell 1 and contact the high-gloss surface 11, thereby producing scratches on the high-gloss surface 11 that are difficult to remove;

[0006] (4) Due to the scratches produced by the resin abrasive on the high-gloss surface 11, the high-gloss surface 11 must be separately subjected to secondary CNC high-gloss processing, that is, the prior art requires at least two CNC stations to complete the high-gloss processing, and the two CNC Processing produces cumulative tolerances in the manufacturing process, which can easily cause dimensional fluctuations, unstable processing yields, and increase material turnover and manpower requirements, increasing costs
