Title:
LASER BEAM PROCESSING MACHINE AND METHOD FOR DETECTING STATE OF OPTICAL COMPONENT
Document Type and Number:
WIPO Patent Application WO/2019/216040
Kind Code:
A1
Abstract:
According to the present invention, a beam irradiation unit (a collimator unit 30, a processing head 35, and a nozzle 36) has a plurality of optical components for converting a laser beam, which is emission light, into collimator light and then focusing the collimator light to irradiate sheet metal (W). A light detection element (a photodiode 404) detects the intensity of light reflected from an optical component being inspected among the plurality of optical components. A control device (an NC device 50) controls a laser beam serving as inspection light so that the laser beam is emitted onto a pierced region after a piercing process performed in order to manufacture a product by cutting the sheet metal W, and compares the intensity of the reflected light detected by the light detection element when the inspection light is emitted and a threshold to detect for the presence of degradation of the optical component being inspected, or to detect the degree of the degradation.
