Abstract

The invention relates to the technical field of laser processing, in particular to a metal colorful marking system and a marking method. The metal colorful marking system comprises a processing platform, an optical fiber laser, a vibrating galvanometer, a lens and a marking control system. The processing platform is used for placing a metal sample; the optical fiber laser is used for emitting laser beams; the vibrating galvanometer is used for controlling deviation of the laser beams; the lens is used for focusing the laser beams to the surface of the metal sample; the marking control system is used for controlling emission of laser and the emitting parameters as well scanning parameters of the vibrating galvanometer. The metal colorful marking system provided by the invention can controlemission of laser and adjust the emitting parameters of laser as well as the scanning parameters of the vibrating galvanometer; by adjusting and combining the parameters, oxidizing films of differentthicknesses can be formed on the surface of the metal so as to obtain the metal with a colorful effect, even a colorful pattern surface.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a metal color marking system and a marking method. Background technique [0002] 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. At present, the metal laser color marking technology usually uses solid-state lasers such as Nd:YAG. Solid-state lasers have serious temperature effects and high heat generation. Water-cooling devices are required to ensure the normal and continuous use of solid-state lasers, and the conversion efficiency of solid-state lasers is relatively low. ; In addition, the existing metal laser multi-variable color marking technology generally only adjusts the processing efficiency and color by changing one parameter, so the processing efficiency is low and the color combination is p...
