Laser Light Reflector

Abstract

This laser reflector is used to perform surface treatments, such as laser cleaning and surface modification, on the surface of a workpiece using a laser irradiated from a laser processing device. It is used to efficiently surface treat the side area of ​​the workpiece. As shown in the "Reference Perspective View Showing the Names of Each Part," this product is configured with multiple plate-shaped mirror members inserted obliquely into the upper part of a cylindrical base. The multiple mirror members are installed along the circumferential direction of the base. The mirror members are installed so that the surface that reflects the laser light faces upward. Furthermore, cylindrical ports are provided at predetermined positions along the circumferential direction on the upper side of the base. The ports are configured to be connectable to supply pipes (not shown) for supplying gases such as air or nitrogen, allowing the gas to be supplied to the inner area of ​​the base. Furthermore, as shown in the "Reference Cross-Sectional View of Key Parts for Explaining Operation," the workpiece is placed within the area surrounded by the multiple mirror members, and surface treatment is performed by irradiating the workpiece with laser light while scanning it from above to below within the predetermined area. At this time, the top surface of the workpiece facing the laser processing device that irradiates the laser light is surface treated by the directly irradiated laser light. Meanwhile, the side surface of the workpiece that does not face the laser processing device that irradiates the laser light is surface treated by the laser light reflected by the mirror member. Furthermore, while dust is generated when performing surface treatment using laser light, this dust is blown outward from the inner region of the base where the mirror member is installed by the gas supplied from the port, preventing it from adhering to the surface of the mirror member. Furthermore, the mirror member is cooled by the gas supplied from the port, thereby extending the life of the mirror member.
