Embodiment 1

[0033] like figure 1 As shown, a system for laser processing super-hydrophobic surfaces includes a laser 1, a rotating station 2, a laser galvanometer module 3, a spraying module 4, an irradiation robotic arm module 5 and a spraying robotic arm 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 defocus irradiation and laser scribing to the surface of the material to be processed placed on the rotating station 2; the spraying module 4 is used to place it on the rotating station 2. The surface of the material to be processed is provided with primer spraying and Teflon coating spraying; the laser galvanometer module 3 is installed on the irradiation robot arm module 5, the spraying module 4 is installed on the spraying robot arm module 6, and the rotating station 2 The material to be processed placed on the rotating station 2 can be driven to rotate horizontally around the center of the rota...

Embodiment 2

[0053] This embodiment further improves the present invention.

[0054] A third manipulator is also installed. The third manipulator is equipped with a purge module, which can blow out compressed air. When defocusing irradiation, use the third manipulator to synchronously purge the irradiation position to reduce the temperature during irradiation. At the same time, the evaporation effect of the coating solvent is improved; when the material is irradiated, a very thin layer of material on the surface will soften and melt. At this time, the use of compressed air for purging can enhance the movement of the compressed air to guide the surface material, so that the surface of the material is The roughening effect is better.

Abstract

The present invention relates to a system and method for laser processing superhydrophobic surfaces. A combined device with multiple functions of laser irradiation, scribing and spraying is set up. A galvanometer module can be used to realize the functions of irradiation and scribing. At the same time, combined with the spraying module, it can achieve super-hydrophobicity on the surface of metal and resin materials. Processing, the hydrophobicity after processing is better than that of the Teflon coating alone; the processed material is protected by the primer, on the one hand, the Teflon coating is not easy to fall off, and the bonding performance is good, on the other hand, the primer protects Even if the Teflon falls off in an accident, it can be further protected by the primer to prevent corrosion; a unique processing method is adopted, and only one equipment is used to realize the modification of the surface of the material itself and the surface of the primer. , Modification of the surface of Teflon coating; the processing effect is good, no transfer drying is required in the middle, 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 superhydrophobic surfaces. Background technique [0002] Superhydrophobicity is a new type of material that can clean itself where it needs to be clean, and can also be placed on metal surfaces 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, and the surface of the material after falling off is exposed and easy to corrode; [0003] In addition, the hydrophobicity provided by Teflon itself is limited, and there is a need in the art to further improve its hydrophobicity to improve the self-cleaning performance of the material surface. [0004] Application No. CN201910082352.9 discloses a method for preparing a superhydrophobic coating by laser printing,...
