Abstract: A laser machining robot includes a manipulator, a robot controller, and a laser machining head. The robot controller controls the operation of the manipulator. The laser machining head is mounted to the manipulator and scans a laser beam. The laser machining head includes a servomotor for driving a member for scanning the laser beam. The drive of the servomotor is controlled by the robot controller.

Abstract: The laser processing head of the present disclosure includes a collimation lens, a focus lens, a first parallel plate, a first drive unit, a second parallel plate, and a second drive unit. The collimation lens collimates a laser beam having a first optical axis, and the focus lens condenses the collimated laser beam. The first parallel plate shifts the optical axis of the condensed laser beam to a second optical axis. The first drive unit rotates the first parallel plate around a first rotation axis. The second parallel plate shifts the optical axis of the laser beam shifted to the second optical axis, to a third optical axis. The second drive unit rotates the second parallel plate around a second rotation axis. The direction of the first rotation axis and the direction of the second rotation axis are identical.

Abstract: A laser machining head controls an irradiation position of a laser beam on a machining target by rotating a first parallel plate by a first motor and rotating a second parallel plate by a second motor. A first holder holding the first parallel plate has a first rotation angle identification unit, and a second holder holding the second parallel plate has a second rotation angle identification unit. The first rotation angle identification unit has a positioning surface that allows positioning relative to the first parallel plate, and the second rotation angle identification unit has a positioning surface that allows positioning relative to the second parallel plate.

Abstract: A laser machining head includes a collimation lens, a focusing lens, and a nozzle unit. The nozzle unit includes a protective member, an inner nozzle, an outer nozzle, a nozzle holding section, and an orifice. The outer nozzle is disposed outside the inner nozzle and the nozzle holding section holds the inner nozzle and the outer nozzle. The orifice is in contact with the inner nozzle and is interposed between the nozzle holding section and the outer nozzle. The nozzle holding section has a first gas path connecting the air supply port disposed in the nozzle holding section and the orifice. The orifice has a third gas path for connecting a second gas path disposed between the inner nozzle and the outer nozzle, and the first gas path. In the vicinity of the tip of the nozzle unit, an opening connected to the second gas path is disposed.
