GLASS CUTTING APPARATUS

摘要

The present invention provides a glass cutting apparatus comprising: a laser beam generating unit for generating a laser beam which is radiated to the cutting path of glass to be cut and has an oval luminous flux; a light dividing unit for dividing the laser beam, which has been generated by the laser beam generating unit, into a main beam and auxiliary beams; a focusing unit for focusing and radiating the laser beam, which has been divided by the light dividing unit, to the cutting path; and a medium supplying unit for supplying an optical coupling medium between the focusing unit and a glass substrate. The present invention can prevent the occurrence of damage to a glass substrate being cut when cutting glass, allows the cutting of the glass substrate by dividing a single laser beam and then radiating same to the glass, and can simultaneously and uniformly preheat both sides of the cutting line of the glass by auxiliary beams divided from either side of the single laser beam.
