Title
(EN) Laser cutting of glass along a predetermined line
(ZH) 玻璃沿预定线的激光切割
Abstract
(EN) The invention relates to laser cutting of glass along a predetermined line. Disclosed are systems and methods for separating a glass sheet along a predetermined line. Laser beams are generated and shaped into elongated laser beams. Arm members are provided that are pivotally coupled together to form a chain of arm members. Each elongated laser beam is directed therefrom a respective laser beam toward the glass sheet to form a contiguous chain of elongated laser beams thereon a surface of the glass sheet. The arm members can be moved to move the contiguous chain of elongated laser beams along the predetermined line to scoring the glass sheet along the predetermined line.
