Method and control device for manufacturing product shell patterns

Abstract

The invention provides a method for manufacturing product shell patterns, which manufactures patterns on a product shell and comprises the steps of setting a carving proposal according to at least one coating attached to the product shell, and jointly carving the at least one coating according to the carving proposal to obtain the patterns. The invention also provides a control device for manufacturing the product shell patterns. The method and the control device perform pattern carving on the product shell attached with multiple layers of the coatings and remove partial coatings by utilizing laser under the background of background colors of surface layers, and the removed surface layers have different depths and display different colors, so that the patterns with multilayer colorful effects provided with the surface layers, the second layer of the coating, the third layer of the coating, and the like are formed; the method and the control device can obtain the colorful decorative effect of the product shell without needing other carriers, such as a heat transfer film or a masking film and a particular clamp; and the device has a simple circuit and simpler design without offering halftones again, and can manufacture delicate and complicated patterns and make the patterns have certain stereoeffect.

Description

technical field [0001] The invention relates to the field of laser etching, in particular to a method for making a pattern of a product shell and a control device. Background technique [0002] Existing consumer electronic products use different materials and decorations in different parts according to their usage, design, and adaptation to specific environments, so as to prolong product life, increase aesthetics, and practicability. [0003] Taking the casing as an example, the existing electronic product casing can obtain color pattern effects through double injection molding, spraying after single-color injection molding, silk screen printing after single-color injection molding spraying, water transfer printing technology, two-color electroplating or thermal transfer printing, etc. These solutions are respectively There are defects such as expensive equipment, insufficiently fine patterns, prone to pattern distortion, difficulty in ensuring mass production uniformity, ne...

AI Technical Summary

Problems solved by technology

Since the output power of the existing laser etching machine is fixed and the engraving depth is fixed, an expensive laser is needed to change the engraving depth, and the cost of pattern making is too high; and this technology needs to engrave multiple coatings layer by layer. When there are many coatings The pattern making process is complicated and time-consuming
