LASER PROCESSING HEAD AND LASER PROCESSING SYSTEM

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 toward a workpiece (W) and reflects most of the second laser beam toward the workpiece; a workpiece-side cond...

Zusammenfassung: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 toward a workpiece (W) and reflects most of the second laser beam toward the workpiece; a workpiece-side condensing lens that condenses each laser beam to irradiate the workpiece with each laser beam; 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 each laser beam to irradiate the image sensor with the condensed laser beam; 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.
