Abstract
A coating removing device includes a coating thickness gauge configured for detecting a thickness of a coating layer formed on a surface of a article. A controller configured for determining an intensity of a laser beam needed to be emitted according to the thickness of the coating layer detected by the coating thickness gauge. In addition, a laser emitter emits the laser beam to the coating layer to remove the coating layer, the laser beam having the intensity determined according to the thickness of the coating layer. The intensity and energy of the laser beam arrived the surface of the article is changed over the coating thickness on the surface, the coated adhesive layer of the PCB is removed, and the appearance of the PCB will not be damaged.
