Abstract
A laser robot for workpiece machining has a first robot link with a robot hand. A first beam path of a first laser beam is arranged on the longitudinal axis of the first robot link and deflected at an end facing a workpiece into an axis-parallel second beam path. A third beam path guides a second laser beam axis-parallel to the first beam path. Focusing optics are arranged in the robot hand. The two laser beams are guided by the focusing optics onto the workpiece. An optical beam combination device is arranged in one of the first and second beam paths for combining the two laser beams acting simultaneously on the workpiece. The two laser beams are guided from the optical beam combination device to the focusing optics simultaneously and axis-parallel or with coinciding axes and from the focusing optics to the workpiece simultaneously axis-parallel or with coinciding axes.
