Method and device for separating a plan plate made of brittle material into several individual plates with a laser

摘要

in a process to separate the components of a flat plate (1) consisting of brittle material e.g. glass into numerous individual sections of pre-defined dimensions (3), the material is subject to laser-induced thermal stress to create separation lines. The thermally stress plate (4) is placed on in contact with an adhesive foil (6) held taut within a surrounding frame. The foil is then expanded by vacuum suction to form the fracture lines. Further claimed is a commensurate workbench.
