Laser machining apparatus

Abstract:

A laser machining apparatus 1 includes: a laser head that is supported by a laser moving device so as to be movable in X, Y, and Z directions above a motor driven conveyor that transports a workpiece loaded thereon. The laser head includes protection glass for protecting a laser focusing lens; an ultraviolet irradiation device disposed beside the conveyor such that a laser light axis and an ultraviolet ray axis are parallel to each other; and a control device that controls the components of the laser machining apparatus so that the ultraviolet irradiation device radiates UV rays on the protection glass in a state in which a UV irradiation port faces a laser irradiation port of the laser head, thus cleaning the protection glass without removing it from the laser head.
