DEVICE FOR CUTTING OF NONMETAL

摘要

The present invention provides an apparatus for cutting nonmetal including glass stably, by which the glass substrate for fabricating a module of a display such as TFT-LCD, PDP and OLED can be cut fast and stably with precision without causing a damage to the substrate to enhance productivity and throughput. The present invention includes a laser beam generator (10) generating a UV short wavelength laser beam, an optical system (11) guiding a beam path of the short wavelength laser beam generated from the laser beam generator (10) to a portion specified for irradiation, a torch (6) condensing to apply the short wavelength laser beam to a specific location on a nonmetallic substrate to be cut, and a relative movement means for allowing the substrate and the laser beam to make a relative movement to cut the substrate.
