Embodiment 1

[0033] Such as figure 1 As shown, a system for laser processing superhydrophobic surfaces, including a laser 1, a rotary station 2, a laser galvanometer module 3, a spraying module 4, an irradiation manipulator module 5 and a spraying manipulator module 6;

[0034] The laser 1 is connected to the laser galvanometer module 3, and the laser galvanometer module 3 is used to provide laser out-of-focus irradiation and laser scribing to the surface of the material to be processed placed on the rotary station 2; The surface of the material to be processed on the surface provides primer spraying and Teflon coating spraying; the laser galvanometer module 3 is installed on the irradiation manipulator module 5, the spraying module 4 is installed on the spraying manipulator module 6, and the rotary station 2 It can drive the material to be processed placed on the rotating station 2 to rotate horizontally around the center of the rotating station 2; the irradiation manipulator module 5, th...

Embodiment 2

[0053] This embodiment further improves the present invention.

[0054] A third mechanical arm is also installed. The third mechanical arm is equipped with a purge module, which can blow out compressed air. When performing defocused irradiation, use the third mechanical arm to perform synchronous purge on the irradiation position to reduce the temperature during irradiation. , and at the same time improve the volatilization effect of the coating solvent; when the material is irradiated, a very thin layer of material on the surface will soften and melt. Roughening works better.

Abstract

The invention relates to a system and method for laser processing of a super-hydrophobic surface. Combined equipment with multiple functions of laser irradiation, lineation and spraying is arranged, the functions of irradiation and lineation can be achieved through one galvanometer module, meanwhile, the galvanometer module is combined with a spraying module, super-hydrophobic processing on the surfaces of metal and resin materials can be achieved, and the hydrophobic performance is better than that of an independent Teflon coating after processing is completed; due to the fact that the processed material is protected by primer, on one hand, a Teflon coating is not prone to falling off, bonding performance is good, and on the other hand, the primer plays a protection role, even if Teflon falls off under an unexpected condition, the material can be further protected by the primer, and corrosion is prevented; a unique processing mode is adopted, and modification of the surface of the material, modification of the surface of the primer and modification of the surface of the Teflon coating are achieved only through one equipment; and the processing effect is good, transfer drying is not needed midway, and the processing efficiency is higher.

Description

technical field [0001] The invention relates to the field of laser material processing, in particular to a system and method for laser processing super-hydrophobic surfaces. Background technique [0002] Super-hydrophobic is a new type of material, it can clean the places that need to be clean by itself, and it can also be placed on the metal surface to prevent external corrosion. In the prior art, Teflon coating can generally be applied on the surface of the material to achieve a hydrophobic effect; however, the Teflon coating has a poor bonding effect and is easy to fall off. After the fall off, the surface of the material is exposed and easy to corrode; [0003] In addition, the hydrophobicity provided by Teflon itself is limited, and the field needs to further improve its hydrophobicity to improve the self-cleaning performance of the surface of the material. [0004] Application number CN201910082352.9 discloses a method for preparing superhydrophobic coatings by laser ...
