Description

Technical Field

[0001] The utility model relates to the technical field of engraving, in particular to a surface engraving device. Background Art

[0002] Nowadays, consumers have diverse demands for products. They will engrave the surface of products according to requirements, or in industry, due to the demand for a certain function of electronic components, equipment is used to engrave products.

[0003] Most of the existing surface engraving devices use laser engraving machines to engrave workpieces with the laser generated by a laser pen. However, during the working process of the laser pen head, it will be affected by pollutants such as dust, smoke, and debris. These pollutants will adhere to optical elements such as focusing lenses and protective lenses, reducing the transmittance of the laser, thereby affecting the energy output of the laser and the engraving effect.

[0004] Especially when engraving aluminum products, the laser ablates the surface of the aluminum products, and the aluminum products will quickly cool and solidify into tiny particles. Moreover, the tiny particles may undergo a chemical reaction to generate aluminum oxide. Aluminum oxide is a powdery substance between a few microns and dozens of microns. Due to the tiny dust particles and the impact force of the laser, the dust particles will fly, making it easy for the dust to enter the laser pen interior. The dust is likely to adhere to the optical elements arranged inside the laser pen head, which will reduce the light transmittance of the optical elements, thereby affecting the laser engraving effect.

[0005] In the prior art, a vacuum cleaner is used to adsorb and clean the generated dust. However, the dust generated by laser engraving of aluminum products is very small, making it difficult for the vacuum cleaner to completely clean it. Secondly, when the vacuum cleaner works, it will generate a strong air flow that may cause vibration, which may cause a slight change in the installation position of the optical elements, affecting the laser calibration. Moreover, the air flow generated by the vacuum cleaner may carry impurities such as dust and particles, and during the gas flow process, these impurities may enter the optical system of the laser pen and contaminate the optical elements.
