The invention discloses a TFT visual positioning precise photoelectric glass cutting machine. The TFT visual positioning precise photoelectric glass cutting machine comprises a rack, a rotating unit arranged on a horizontal supporting plane of the rack, a visual positioning unit which is connected with the rack and is arranged above the rotating unit as well as a cutting unit, wherein the rotating unit is used for rotating a glass substrate and positioning Y axis cutting points, the cutting unit is used for cutting along X axis direction, and a high-definition camera on the visual positioning unit moves, observes, positions and cuts along the X axis direction. The TFT visual positioning precise photoelectric glass cutting machine has the advantages that the high-definition camera is adopted for carrying out visual positioning, a high precision DDR (direct drive rotation) rotation working platform rotates, and a cutting direction is switched, so that accuracy in cutting and 90-degree rotational positioning is guaranteed; and grating ruler feedback cutting is adopted, so that positioning accuracy is high.
Description
technical field [0001] The invention relates to the field of TFT-LCD display screen processing, in particular to a TFT visual positioning precision photoelectric glass cutting machine. Background technique [0002] With the rapid development of liquid crystal display technology, thin-film transistor active-matrix liquid crystal display (TFT-LCD) has become the leading technology in the field of information display and the research and development center because of its excellent color saturation, color reproduction ability and high contrast. hotspot. In recent years, the market share of TFT-LCD in high-end flat panel displays is increasing rapidly, but the manufacturing of TFT-LCD photoelectric glass substrates still has the disadvantages of complicated process and low yield rate, especially the cutting / split process, in many The panel factory is also one of the main factors affecting the yield rate of products. Contents of the invention [0003] The technical problem to ...
