GLASS CUTTING DEVICE

摘要

PURPOSE: A glass cutting device is provided which generates laser beam for cutting and also generates auxiliary laser beam on the front part of the cutting line to distribute stress symmetrically or asymmetrically along the cutting line and thus cuts any part of the flat glass to be vertical or sloped at certain angle. CONSTITUTION: The glass cutting device comprises: (i) a supporting stand(15) which fixes a flat glass to be cut(10); (ii) a laser cutting equipment(12) which is placed on the upper side of the glass having regular intervals and generates laser beam to supply required heat for cutting to the cutting line(L1) of the glass; (iii) an auxiliary laser equipment(11) which is installed on the front side of the laser cutting equipment and generates auxiliary laser beam to cut the cutting part of the glass to be vertical or sloped at certain angle; and (iv) a cooling equipment which is placed on the rear side of the laser cutting equipment and sprays cooling agent through a cooling nozzle on the heated glass to cut the glass.
