Abstract:
A laser robot for workpiece machining, comprising:a first robot link (10) having a longitudinal axis (11); a robot hand (3536) connected to the first robot link (10); a first beam path (12) configured to guide a first laser beam (13) and arranged on the longitudinal axis (11) of the first robot link (10), wherein the first beam path (12) is configured to be deflected at an end facing a workpiece (18) into an axis-parallel second beam path (14); a third beam path (15) configured to guide a second laser beam (16) and arranged axis-parallel to the first beam path (12) of the first laser beam (13); focusing optics arranged in the robot hand (35, 36) downstream of the first robot link (10), wherein the first and second laser beams (13, 16) are guided by the focusing optics onto the workpiece (18); an optical beam combination device arranged in one of the first and second beam paths (12 or 14) of the first laser beam (13) for combining the first and second laser beams (13, 16) acting simultaneously on the workpiece (18); wherein the first and second laser beams (13, 16) are guided from the optical beam combination device to the focusing optics in the robot hand (35, 36) simultaneously and axis-parallel or with coinciding axes; and wherein the first and second laser beams (13, 16) are guided from the focusing optics to the workpiece (18) simultaneously axis-parallel or with coinciding axes.
