Abstract

The invention discloses a laser marking method for an anodic aluminum oxide surface. The laser marking method comprises the steps that the anodic aluminum oxide surface is cleaned; a laser system is adopted for emitting laser beams to the anodic aluminum oxide surface so as to blacken the anodic aluminum oxide surface or remove dye on the anodic aluminum oxide surface; the laser system comprises alaser generator and a control system, and the laser generator is a nanosecond laser device or a picoseconds laser device; and the control system is used for setting the laser parameters of operatingof the laser generator, and the laser parameters comprise the field lens focal length, the pulse width, the power, the repetition frequency, the marking speed and the filling density. By means of thetechnical scheme, a blocking layer and metal aluminum of anodic aluminum oxide are not destroyed, the destroy force of lasers to the anodic aluminum oxide surface is reduced, and products are not prone to being corroded by the environment.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a laser marking method on the surface of anodized aluminum. Background technique [0002] Anodized aluminum refers to a layer of dense aluminum oxide on the surface of aluminum or aluminum alloy to prevent oxidation of aluminum or aluminum alloy. Although the chemical properties of anodized aluminum are the same as those of aluminum oxide formed by natural oxidation, the corrosion resistance, wear resistance and decorative properties of anodized aluminum are better than those formed by natural oxidation. [0003] Anodized aluminum casings are traditionally used in electronic products such as mobile phones, tablets and laptops. Existing laser marking on anodized aluminum is usually tactile. The process is to destroy the anode layer on the metal surface by laser. In this way, on the one hand, the marking part will be easily corroded by the environment, and on the other ha...
