METHOD FOR MANUFACTURING FLAT GLASS SHEET AND METHOD FOR DIVIDING GLASS SUBSTRATE |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To improve the cutting speed in a glass cutting system to divide a large glass sheet into small pieces. <P>SOLUTION: A laser beam having the thin and long beam spot shape of ≥30 mm in maximum dimension is transferred across the glass sheet to generate a local crack notch line, and then the glass sheet is divided along the notch line by adding the bending moment in the local crack region. <P>COPYRIGHT: (C)2012,JPO&INPIT |
