Method of etching cd pattern on the surface of substrate and laser cutting to form logo

Abstract

The invention provides a method for conducting CD pattern corrosion machining and laser cutting on the surface of a base material to form a LOGO. The method comprises the first step of mask plate manufacturing, the second step of light resistance film coating and baking, the third step of exposure and baking, the fourth step of developing and baking, the fourth step of etching and the sixth step of laser cutting. The method is high in efficiency and precision and wide in application range. Due to the fact that the surface of the base material is polished, and CD patterns are provided with many convex blocks microcosmically, irradiation of light to the surface of the base material is equivalent to the fact that chromatic dispersion of many small prisms can occur, and different colors are presented. Due to the fact that the CD patterns are etched on the base material, the risk of falling cannot happen, and the colorful effect is more lasting.

Description

technical field [0001] The invention belongs to the technical field of surface treatment, and in particular relates to a method for etching CD lines on the surface of a substrate and laser cutting to form a LOGO. Background technique [0002] With the development of society, people's requirements for beauty are getting higher and higher. The LOGO that will be used in many fields is no longer a single color. The surface of the polished substrate is etched to produce CD patterns like many small ones. Prism, when visible light is irradiated on the surface, it will disperse and present a colorful and dazzling effect. With the advancement of science and technology, the current optical fiber cutting machine has the characteristics of small focusing spot, fine cutting line, high processing precision and low energy consumption. It can realize High-precision LOGO cutting, and the edge damage area is small, which will not affect the appearance of LOGO. [0003] The existing CD patter...

Problems solved by technology

However, the ink used in this patent is printed on the surface of hard materials, the adhesion is not high enough, it is easy to fall off, it cannot prevent scratches, the processing accuracy is not high, and it is impossible to make nano-level CD patterns. In addition, due to the high power density of laser cutting The laser beam irradiates the material to be cut, so that the material is quickly heated to the melting temperature, the silk screen layer cannot withstand such a high temperature, and the edge ablation layer is large during laser cutting, which will affect the aesthetics of the LOGO

[0007] For the third processing method, the cost of CD pattern mold is high, the mold life is short, and the molding efficiency is low, which is only suitable for the base material of plastic material
