Title:
LASER ENGRAVING MACHINE FOR PROCESSING SURFACE AND INNER OF GLASS
Document Type and Number:
WIPO Patent Application WO/1999/000215
Kind Code:
A1
Abstract:
The present invention relates to a laser engraving machine for processing surface and inner of glass. The machine comprise a floor frame, a CO¿2? laser, a YAG laser, an indicating He-Ne laser, a spreading beam telescope and a mirror which are disposed on an upper platform of the floor frame. A CO¿2? laser focusing device and a YAG laser focusing device are suspended from the upper table. A two-dimensional operating table is installed under the laser focusing device. A water-cooling device, a laser power box and a computer are disposed beside the floor frame. The CO¿2? laser is focused on the glass surface to make it cracked and to achieve plane-engraving. The focusing lens group of the YAG laser focusing device is moved up-and-downwardly, so that the point damaged inside the glass forms a three-dimensional pattern to achieve inner-engraving.
