Abstract

The system comprises a buckling arm robot with a robot frame (1) and an articulated arm (2) and a fiber optic cable (5) which is connected to one end of the articulated arm (2) and through which a laser beam (11) with a beam axis (10) is coupled into the articulated arm (2) in the direction of a first axis of the articulated arm (2). The fiber optic cable (5) is indirectly connected to the stationary end of the articulated arm (2) via an alignment unit (6) which comprises a collimating lens system (13) and at least two alignment mirrors (12.1, 12.2), each of which mirrors can swivel about at least one axis of rotation and move along at least one axis of translation, with the axes of rotation and the axes of translation being disposed at right angles to each other so that the beam axis (10) of the laser beam (11) can be made to coincide with the optical axis (4).
