Abstract

The invention provides a device for removing white spots caused by thermal residual stress on the surface of a material, including a laser; an X oscillating mirror for reversing the laser light from the laser; The laser of the X galvanometer is reversing; the focusing lens is used to adjust the light intensity of the laser passing through the Y galvanometer, and guide the laser light after adjusting the light intensity to the surface of the material to remove white spots on the surface of the material. The laser emitted by the device provided by the invention can melt the white spots on the surface of the material, and cooperate with the focusing lens in the device to blur the material around the white spot, so that it can be restored from the crystalline state to the amorphous state, so as to achieve the removal of the white spot The purpose, and will not cause other residual stress generation.

Description

technical field [0001] The present invention relates to a device, more specifically, to a device and method for removing white spots caused by thermal residual stress on the surface of a material. Background technique [0002] At present, hot and cold in the process of material manufacturing or post-processing, or long-term heating / cooling will cause thermal residual stress in the material, and for plastic or polymer materials, thermal residual stress will often make the material Certain components or small additives are induced to crystallize or atomize to precipitate white spots on the surface of the material. The general method for removing white spots in the industry is to wipe the white spots with a solvent (such as alcohol) so that the appearance after wiping is consistent with the color of the surrounding area, then put it in an oven, and dry it to remove the solvent. However, the removal of white spots by the above method will cause the generation of chemical residu...
