Abstract
An arrangement for machining workpieces by a laser, particularly for cutting, perforating, notching, engraving, drilling and inscribing workpieces with three-dimensional structures of different sizes. The laser beam is directed to the workpiece, which is fixed on a holding device, by means of a robot-guided articulated mirror arm and a laser scanner. The laser beam is guided by a coordinated time-controlled and position-controlled deflection of the articulated mirror arm and of the mirror elements of the laser scanner.
Claims5
An arrangement for machining workpiece surfaces extending in three dimensions by a laser, comprising:
- a stationary laser;
- an articulated mirror arm,radiation of the laser being coupled into a first end of the articulated mirror arm;
- a robot arm connected to a robot for guiding the second end of a articulated mirror arm;
- a holding device for fixing a workpiece;
- at least one gas nozzle by which a flow of gas is directed to the workpiece surface;
- a control device for controlling the laser and robot arm;
- a laser scanner being fastened to the robot arm and connected to the articulated mirror arm in such a way that the beam exiting from the second end of the articulated mirror arm is coupled into the laser scanner;
- said gas nozzles being arranged at the laser scanner so as to be movable in such a way that they can be directed to the workpiece surface by a gas nozzle propulsion unit communicating with the control device;
- wherein gas flow and the radiation exiting from the laser scanner via an exit face coincide at a point on the workpiece surface.
