SCANNER APPARATUS FOR A POWER LASER WELDING DEVICE WITH A DEFLECTION MIRROR THAT IS PIVOTABLE ABOUT TWO AXES

摘要

The invention relates to a scanner apparatus for a power laser for machining material. Said scanner apparatus comprises an imaging optical device (8) that is provided with a deflection mirror (9) which is mounted so as to be pivotable about two axes and is driven by two actuators (11, 21), and by means of which the laser beam can be projected onto machining points of workpieces as a spot. Coupling means (14, 24) which are pivotally mounted on the actuators (11, 21) at one end while being pivotally mounted on the deflection mirror (9) at a second end are provided between the actuators (11, 21) and the deflection mirror (9) such that the force of inertia acting upon the swivel bearing is minimized, which in turn allows the swiveling process to be accelerated.
