Embodiment Construction

[0035] Please refer to figure 1 , is a flowchart of a method for processing a three-dimensional surface pattern of a workpiece according to an embodiment of the present invention. Please also refer to figure 1 and figure 2 , as in step S110 , the first anodic treatment is performed on a workpiece 100 , as can be seen from the figure, the surface of the workpiece 100 is a three-dimensional surface, which is composed of at least one plane 110 and one arc 120 . In this embodiment, the first anodic treatment is hard anodic treatment, and a first anode layer L1 is formed on the surface of the workpiece 100, and the thickness of the first anode layer L1 is about 30 micrometers (m).

[0036] Next, please also refer to the figure 1 and image 3 , such as step S120, providing a pattern film 200, the pattern film 200 includes a release material 210 and an acid and alkali resistant ink layer 220 disposed on the release material 210, wherein the release material 210 is a flexible sub...

Abstract

The invention discloses a pattern treatment method for a workpiece surface. The method at least comprises the following steps of: performing first anodizing treatment on a workpiece, wherein the workpiece surface consists of at least one plane and at least one cambered surface; providing a pattern membrane, wherein the pattern membrane comprises a release material and an acid-base-resistant ink layer configured on the release material, and the face of the release material, which is provided with the acid-base-resistant ink layer, faces the workpiece; applying acting force to the edge of the pattern membrane to attach the pattern membrane to the surface of the workpiece so as to transfer a pattern of the acid-base-reistant ink layer to the surface of the workpiece; removing the release material; etching the workpiece and removing the acid-base-resistant ink layer; and performing second anodizing treatment to form a bicolor anode three-dimensional texture on the workpiece surface.

Description

technical field [0001] The invention relates to a method for treating the surface of a workpiece, and in particular to a method for patterning the three-dimensional surface of the workpiece. Background technique [0002] Aluminum, titanium and their alloys have the advantages of high strength and light weight, so they are widely used in aviation, electronics, communication and other fields. Taking the casing of a notebook computer or a mobile phone as an example, in order to enhance the aesthetics and visual effects of the product, anodic treatment or painting can be used to increase the variety of patterns on the casing. [0003] However, in the known anodic treatment process, although the color of the surface oxide layer can be controlled by the voltage change between the two poles, the thickness of the oxide film is uniform, and there is no concave or convex three-dimensional effect. In addition, although there has been developed a method that can use multiple anodic tre...
