1. a laser processing device, cutting workpiece is become the phase along the processing preset lines irradiating laser bundle of workpiece by itHoping shape, above-mentioned processing preset lines includes straight line and curve, and this laser processing device has:

  • Work stage, it loads workpiece;

    Laser beam output unit, its outgoing laser beam;

    Deflection unit, it has at least one the wedge shape rib for making the laser beam deflection from the injection of laser beam output unitMirror;

    Collecting lens, the laser beam after it makes by above-mentioned prism wedge converges in the processing preset lines of workpiece;

    Scanning element, it scans the laser beam after assembling, to be become by above-mentioned cutting workpiece along the processing preset lines of workpieceIntended shape;

    AndRotation control unit, is scanning above-mentioned laser beam so that above-mentioned cutting workpiece is become intended shape along processing preset linesTime, this rotation control unit makes above-mentioned prism wedge rotate around optical axis according to the scanning direction of laser beam, so that above-mentionedThe convergent point of the laser beam that collecting lens is formed converges at a bit on the optical axis of the laser beam inciding prism wedge,When scanning above-mentioned laser beam along processing preset lines, in the case of processing preset lines is straight line, to wedge shape ribThe rotation of mirror is controlled so that from the optical axis of the laser beam of above-mentioned collecting lens outgoing when above-mentioned workpiece is overlooked withStating processing preset lines vertical, in the case of processing preset lines is curve, the rotation to prism wedge is controlled, and makesMust from the optical axis of the laser beam of above-mentioned collecting lens outgoing when above-mentioned workpiece is overlooked with the tangent line of above-mentioned processing preset linesVertically.
