Abstract

The invention discloses a laser processing device and method for realizing super-hydrophobic metal micro parts. The laser processing device comprises a forming system, a modification system, a cleaning system, a clamp assembly and a control assembly; the clamp assembly clamps a to-be-machined workpiece to sequentially pass through the forming system, the modification system and the cleaning system; the control assembly controls the forming system, the modification system, the cleaning system and the clamp assembly. A microstructure is prepared on the surface of the workpiece through a laser shock impressing technology, and then the microstructure is modified with a low-surface-energy modification solution and further cleaned with absolute ethyl alcohol, so that the super-hydrophobic surface is obtained. The device and the method have the beneficial effects that modules with different functions are adopted, and the modules can be changed according to processing requirements in the processing process to achieve different functions of the surface of the workpiece; the whole processing process can be automatic and can be completed under one-time clamping, the machining efficiency is high, operation is convenient, and the production cost can be effectively saved.

Description

technical field [0001] The invention relates to a laser processing device and a processing method, in particular to a laser processing device and a processing method for realizing superhydrophobic metal micro parts, and belongs to the technical field of laser processing. Background technique [0002] Super-hydrophobicity is a kind of water-repelling property on the surface of materials, and it is one of the important characteristics of solid surfaces. This phenomenon is very common in daily life. In experiments, super-hydrophobicity is defined by the contact angle of the material surface being greater than 150°. Superhydrophobic surfaces have applications in self-cleaning, anti-icing and frosting, anti-corrosion and drag reduction properties. There are many methods for the preparation of super-hydrophobic surfaces. The basic principle is that both the surface micro-nano structure and the free energy of the surface of the metal material simultaneously determine the super-hydr...
