Problems solved by technology

[0003] At present, the beautification process of the metal casing of notebooks on the market is mostly direct printing. However, the patterns printed directly on the metal are easily worn out. Some also use transfer printing to cover the film, but the patterns on the transfer film are not easy to bond with the metal. , Improper handling after transfer, making the transfer layer still not wear-resistant

Abstract

The invention discloses a laser etching appearance treatment process for a notebook computer metal shell. The process comprises the following steps of (1) cleaning the notebook computer metal shell, and preparing a laser emitter; (2) according to designed etching data, performing laser etching on the surface of the notebook computer metal shell cleaned in the step (1) through the laser emitter, wherein power of the laser emitter is 2.5-4.5 W, and the frequency of the laser emitter is 15-20 KHz; and (3) cleaning the notebook computer metal shell etched in the step (2) again. According to the laser etching appearance treatment process for the notebook computer metal shell, the laser emitter with certain power and frequency is adopted for treating the notebook computer metal shell, and patterns and characters on the surface of the notebook computer metal shell treated through the process have the effects of being three-dimensional, attractive and novel in vision; and the surface roughnessand the concave-convex depth of the patterns are controllable, so that the appearance and style of the notebook computer metal shell are enriched.

Description

technical field [0001] The invention belongs to the technical field of notebook appearance treatment technology, and in particular relates to a laser etching appearance treatment technique for a metal shell of a notebook. Background technique [0002] With the development of society, office equipment is becoming more intelligent, personal computers are becoming smaller and smaller, and the use design is becoming more and more user-friendly. Among them, notebook computers are widely used due to their exquisite and small size. With the continuous development of computer technology, the production of computer notebook casings is becoming more and more colorful. The development trend of notebook computer products is to be ultra-thin, and the metal appearance with thin and light characteristics has become popular. [0003] At present, the beautification process of the metal casing of notebooks on the market is mostly direct printing. However, the patterns printed directly on the ...
