Device for position control of a laser machining beam

摘要

A device for the position control of a laser machining beam relative to topographical structural markers in surfaces of workpieces, includes a control mechanism, a laser beam feed mechanism for providing a laser machining beam, and a laser beam positioning mechanism, and an optical recognition mechanism for the structural markers with an illumination mechanism for producing a parallel beam bundle, which illuminates the surface with the structural markers to be recognized in a scanning field, and a camera detecting the scanning field for recording the beam bundle, which is reflected by the surface and changed by the structural markers, wherein the camera image can be evaluated by the control mechanism to recognize the position of the structural markers and for the corresponding position control of the laser machining beam.
