Laser Light Reflector

Abstract

This article is a laser beam reflector 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 article 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 surfaces that reflect the laser beam face upward. Also, as shown in the "Reference Cross-Sectional View of Main Parts for Explaining Operation," the workpiece is placed within an area surrounded by the multiple mirror members, and surface treatment is performed by irradiating the workpiece with a laser beam from above to below while scanning the area. In this case, the top surface of the workpiece facing the laser processing device that irradiates the laser beam is surface treated by the directly irradiated laser beam. Meanwhile, the side surface of the workpiece facing away from the laser processing device that irradiates the laser beam is surface treated by the laser beam reflected by the mirror members.
