METHOD AND DEVICE FOR CUTTING A FLAT GLASS PLATE INTO A NUMBER OF RECTANGULAR PLATES |
摘要 |
<p>The cutting of the flat glass plate (1) into rectangular plates with a predetermined edge length is performed by forming initial cracks at the beginning of cutting lines on the glass plate and moving a laser beam along the cutting lines followed by a cooling spot to induce a thermo-mechanical stress alone the cutting lines. First the glass plate (1) is cut apart into partial plates (2-5) along first parallel cutting lines spaced according to the predetermined edge length. Then the cut apart glass plate is rotated by 90° and the partial plates (2-5) are moved apart from each other. Subsequently the partial plates that have been moved apart are cut apart alone several parallel second cuts (4-9) perpendicular to the first cuts. This method facilitates exact placement of the initial cracks.</p> |
