LASER SEPARATION METHOD OF GLASS SHEET

摘要

PROBLEM TO BE SOLVED: To separate a glass sheet by only translating a laser beam and a cooling area along the surface of the glass sheet only once without the need for a scribing step. SOLUTION: The length and the translation speed (less than 200 mm/s) of an elongated laser beam 14 having a length of≥100 mm are selected so that the maximum temperature generated at the surface of the glass sheet 12 by the translation of the laser beams 14 along the surface of the glass sheet 12 is at least by about 150°C lower than a strain point of the glass.
