Laser apparatus

Abstract

The invention relates to a laser device which comprises a laser oscillator, a lens frame assembly, a corrector, a diagnosis module, a calculation module and a controller. The diagnosis module re-diagnoses whether or not the optical path bend occurs by re-calculating an optical path difference between the processing optical path and the reference processing optical path, the optical path difference being changed by the drive motor according to the target drive speed and the target drive time. When the optical path difference after the recalculation is greater than the reference optical path difference, the calculation module recalculates the target drive speed and the target drive time based on the optical path difference after the recalculation. The controller redrives the drive motor according to the recalculated target drive speed and the recalculated target drive time.

Description

technical field [0001] The present invention relates to laser devices. Background technique [0002] Recently, in the field of processing devices such as cutting devices, marking devices, etc., the use of laser beams having excellent physical characteristics is increasing day by day. [0003] Generally, a laser device includes: a laser oscillator that generates a laser beam to oscillate; an optical system that transmits the laser beam oscillated in the laser oscillator according to a preset transmission method; and a laser nozzle that condenses the laser beam transmitted through the optical system. Light is irradiated to the object to be processed. [0004] On the other hand, if the correction state of the optical components installed in the optical system changes due to external force and vibration, wear and aging of the structural elements of the laser device, and other reasons, so that the optical path of the laser beam is bent, the laser beam It will be sent to the las...

Problems solved by technology

Therefore, the laser beam emitted from the laser nozzle irradiates the object to be processed in a state deviated from the predetermined processing position, thereby adversely affecting the processing quality of the object to be processed.

[0005] Therefore, the existing laser device does not include a structure capable of diagnosing and correcting the bending of the optical path of the laser beam, and thus cannot quickly cope with the bending of the optical path of the laser beam.
