LASER PROCESSING SYSTEM AND LASER PROCESSING METHOD FOR CONTINUOUS ROLL PATTERNING

摘要

The laser processing system of the present invention is a laser processing system for processing a roll surface along a predetermined processing pattern while scanning a laser beam, the laser processing system comprising: a laser oscillator for generating and outputting a laser beam; A galvanometer scanner for scanning and irradiating the laser beam onto the surface of the roll, a rotary stage for supporting the roll while rotating the roll with respect to the rotation axis, a galvanometer scanner for scanning the laser beam along the processing pattern, And a control device for controlling the driving of the laser scanner, the meter scanner, and the rotary stage, wherein the laser beam is irradiated to the roll surface, the reference laser beam being perpendicular to the center path of the laser beam, The distance between the focal depth virtual plane spaced by the focal depth (DOF) Within and a processing controller which is set up to roll processing scan area of the scanner, no galvanic meter location.
