  • Patent number: 8110776
    Abstract: Glass substrate cutting apparatuses using lasers are disclosed, where a laser cutting head is moved. A glass substrate cutting apparatus includes two parts for a laser cutting head: heavy laser beam generators fixed to respective ends of a gantry structure moving in parallel along two gantry stages located on either side of a cutting table, and relatively lightweight laser irradiation heads moving horizontally in parallel with the gantry structure. The glass substrate cutting apparatus includes a cutting table for maintaining a glass substrate in a horizontal state; biaxial gantry stages for moving a gantry structure along the cutting table; the gantry structure moving in between an upper part of the biaxial gantry stages; laser beam generators fixed to respective ends of the gantry structure for oscillating the laser; and laser irradiation heads that move horizontally on respective ends of the gantry structure and irradiate the laser upon the glass substrate.

  • Patent number: 8084711
    Abstract: Disclosed herein are apparatuses for breaking a glass panel unified with a process table which break the glass panel formed with scribing lines along the scribing lines by irradiating laser beams. The apparatuses for breaking a glass panel unified with a process table to conduct breaking operations of the glass panel after scribing work of the glass panel as one body with the process table are installed on both sides of the process table included in a transfer-type cutting head laser cutting device. Each apparatus for breaking the glass panel unified with the process table comprises: breaking bars for cutting the glass panel by applying pressure to cutting sections of the glass panel; rotating devices for rotating the breaking bars by combining with both ends of the breaking bars; and a support equipped with cylinders for vertically moving the rotating devices in both sections.
