Problems solved by technology

[0004] Use laser to mark on the anode layer of aluminum alloy, but the laser has serious thermal damage and thermal diffusion to the material, and the hot edge effect often makes the mark blurred, especially for marking thinner materials such as mobile phone shells. The heat loss is more obvious when

Abstract

The invention discloses a device for marking on surface of an aluminum alloy anode layer by using laser. The device comprises a base, wherein a Z-direction guide rail is fixed to one side of the base;a Y-direction guide rail is fixed to the Z-direction guide rail; a placing plate is fixed to the Y-type guide rail; a laser is fixed to the upper side wall of the base; and a beam expander positionedat the end part of the laser is also fixed to the upper side wall of the base. A method for marking the surface of the aluminum alloy anode layer by using laser comprises the following step: S1, placing a cleaned workpiece to be marked on the placing plate, and clamping the workpiece through the clamping plate. According to the device and the method, the workpiece is clamped to form opposite clamping, thereby avoiding point support, ensuring a larger stress supporting surface, and avoiding deformation caused by stress concentration; and meanwhile, the flow of cooling water is pushed to adsorbheat by utilizing the heat generated in the marking process so as to adsorb heat; the energy consumption is low; the deformation of the workpiece caused by thermal stress is avoided; and the qualityafter marking is ensured.

Description

technical field [0001] The invention relates to the technical field of workpiece processing, in particular to a device and a method for marking the surface of an aluminum alloy anode layer by using a laser. Background technique [0002] Laser marking technology is one of the largest application areas of laser processing. Laser marking is a marking method that uses a high-energy-density laser to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark. [0003] After retrieval, the application publication number CN 102442082 A discloses a device and method for marking the surface of an aluminum alloy anode layer by using a laser. The device includes a laser for providing a light source for the surface of a laser-processed material; Light expansion, to improve the laser transmission characteristics so that it can better focus the laser to the adjustable beam expander on the surface of the...
