Abstract: A wet laser cleaning apparatus includes a machine base, a laser cleaning module, a shielding housing and a filtering device. A base material is placed in a reservoir of the machine base, into which a liquid is introduced through the filtering device. A control module drives first parallel axial track groups, a second parallel axial track group and a vertical axial track group to move an optical fiber laser knife device of the laser cleaning module to irradiate and clean the base material. A height sensor device and an orientation sensor device sense a position and a height of an object, so that the optical fiber laser knife device can automatically focus on the base material. Dusts produced after the optical fiber laser knife device has irradiated the base material are stored in the liquid, and the filtering device filters the dusts from the liquid.

Abstract: A dry laser cleaning apparatus and a process thereof are provided. The dry laser cleaning apparatus includes a machine base, a laser cleaning module and a shielding housing. A base material is mainly placed on an object support platform of the machine base, so that a control module drives first parallel axial track groups, a second parallel axial track group and a vertical axial track group to move an optical fiber laser knife device of the laser cleaning module, and the optical fiber laser knife device irradiates a surface of the base material to clean the base material. Meanwhile, a height sensor device of the laser cleaning module and an orientation sensor device of the shielding housing are used to sense a position and a height of a to-be-cleaned object, so that the optical fiber laser knife device can automatically focus on the base material to optimize a cleaning effect.
