Problems solved by technology

[0003] In the application process of PC materials, there may be situations where it is necessary to partially blacken transparent PC materials by laser. In the prior art, due to the high refractive index of PC materials themselves, laser processing will cause There are serious cases of explosive spots in the processing area, and a large number of black spots will be produced after the laser penetrates into the material; in this way, the appearance of the final product made of transparent PC material will be unqualified. The transmittance of the product is reduced, which leads to the loss of the function of the product

Abstract

The invention provides an ultrafast-laser-based blackening treatment method and system for a transparent PC part. The blackening treatment method comprises the steps of carrying out atomization treatment on the surface of the transparent PC part, and enabling the surface of the transparent PC part to form a wafer-shaped structure surface with the roughness in a preset range; adjusting the processing surface of the transparent PC part with the wafer-shaped structure surface to be level with a lens of an ultrafast laser; adjusting the laser focus of the ultrafast laser to the surface of the laser area of the processing surface, and adjusting the distance between the laser focus and the laser area to a preset distance range according to the processing effect parameters; and emitting an ultrafast laser through the processing technological parameters of the ultrafast laser, and breaking chemical bonds of a PC material on the surface of the laser area of the transparent PC part so as to obtain the transparent PC part with the blackened surface of the laser area. According to the ultrafast-laser-based blackening treatment method and system, surface blackening treatment can be successfully carried out on the transparent PC part through the ultrafast laser, finally, the laser penetration depth is reduced, and it is ensured that the product appearance and the use function both meet the requirements.

Description

technical field [0001] The invention belongs to the technical field of surface processing of PC parts, and more specifically relates to a method and system for blackening treatment of transparent PC parts based on an ultrafast laser. Background technique [0002] PC (Polycarbonate, polycarbonate) material is a high molecular polymer containing carbonate groups in the molecular chain. PC material has the advantages and properties of fatigue resistance, weather resistance, high transparency, heat resistance and high strength. Therefore, PC materials have played an important role in various industries; for example, PC materials play an extremely important role in the optical field due to their unique characteristics of high light transmittance, high refractive index, high impact resistance, dimensional stability and easy processing. s position. [0003] In the application process of PC materials, there may be situations where it is necessary to partially blacken transparent PC...
