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: Laser processing head (10) includes a bend mirror that bends a second laser beam in a direction intersecting a first laser beam; a dichroic mirror that transmits most of the first laser beam and reflects most of the second laser beam; a workpiece-side condensing lens that condenses the most of the each laser beam to irradiate the workpiece; an image sensor that receives a rest of the first laser beam reflected by the dichroic mirror and a rest of the second laser beam transmitted through the dichroic mirror; a detection-side condensing lens that condenses the rest of the each laser beam to irradiate the image sensor; and an adjuster that adjusts a workpiece-side condensing state on an image plane on a workpiece side. The image sensor detects a detection-side condensing state on an image plane on an image sensor side. The workpiece-side condensing state is adjusted by the adjuster based on the detection-side condensing state.

Abstract: Laser processing head (10) includes housing (11) and a plurality of optical components. Housing (11) includes first and second light entrance ports (12a) and (12b) through which first and second laser beams (A) and (B) are incident, and light irradiation port (13). Second laser beam (B) has a wavelength different from first laser beam (A). The plurality of optical components include bend mirror (30), dichroic mirror (40), aperture (71), and detection-side condensing lens (70). First and second laser beams (A) and (B) transmitted through detection-side condensing lens (70) are received by image sensor (60). Aperture (71) is configured to be able to reduce diameters of first and second laser beams (A) and (B) incident on detection-side condensing lens (70).

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.

Abstract: A laser welding device includes a welding head configured to emit a laser beam to a working point, a shield gas supplying nozzle configured to supply shield gas to the working point, and a high-speed air supplying nozzle configured to supply a high-speed air stream between the shield gas supplying nozzle and the welding head, the high-speed air stream having a flow rate that is larger than a flow rate of the shield gas, and being supplied in a horizontal direction directly above the shield gas supplied to the working point, or in a direction orthogonal to an emission direction of the laser beam. The high-speed air supplying nozzle is disposed in a range from 80 mm to 200 mm, both inclusive, above the working point, or in a range equal to or lower than a half of a working distance between an emission surface of the laser beam of the welding head and the working point, and supplies the high-speed air stream in a belt shape.
