Abstract:
1. A device for cutting a glass sheet, continuously supplied after a melting and solidification process, into quadrangular glass substrates, the glass sheet cutting device comprising: two or more cutters for cutting a glass sheet into quadrangular glass substrates; a defect inspector for scanning the glass sheet to three-dimensionally check defect positions in a length direction, a width direction and a thickness direction of the glass sheet; wherein the cutters comprise: a first cutter for cutting the glass sheet in the width direction (‘Y direction’) into first glass substrates; a second cutter for cutting each of the first glass substrates in the length direction (‘X direction’) into second glass substrates; a third cutter for cutting each of the second glass substrates in the width direction (‘X direction’) into third glass substrates; and a fourth cutter for cutting the third glass substrates in the length direction (‘Y direction’).
