The invention provides a bow shape regulating device for liquid crystal glass and belongs to the field of TFT-LCD liquid crystal substrate manufacture. The regulating device comprises a mounting base,a driving mechanism, a regulating mechanism and a glass guide roller assembly; the driving mechanism and the regulating mechanism are mounted on the same surface of the mounting base and are connected by a transition connecting plate; and the glass guide roller assembly is mounted on the driving mechanism. The invention further provides a bow shape regulating system for liquid crystal glass by utilizing the regulating device. The system comprises four regulating devices which are respectively distributed on the surfaces A and B of the liquid crystal glass at the outlet end of an annealing furnace in a way of every two of the regulating devices form a group, and the four regulating devices are respectively mounted on a beam at an outlet of the annealing furnace at the far and near ends ofthe glass. By using the device and system provided by the invention, the problems such as glass warping, poor thickness and quality standard exceeding caused by the sudden change of a bow shape when the glass passes through the outlet end of the annealing furnace and an upper guide of the outlet of the annealing furnace can be solved, and the effect of stabilizing the product quality and grade isachieved.
Description
technical field [0001] The invention belongs to the field of manufacturing TFT-LCD liquid crystal substrates, in particular to a glass bow used in the process of forming TFT-LCD liquid crystal substrates by overflow method in the manufacturing process of TFT-LCD glass substrates of flat panel displays. A liquid crystal glass bow shape adjustment control device and system for keeping the shape under control. Background technique [0002] Now the domestic TFT-LCD has entered a period of fast-maturing development. The increasingly mature LCD production technology is combined with each other to continuously improve the display quality of products, enhance the automated large-scale production capacity, greatly increase output, increase pass rate, and reduce costs. [0003] As the key material of liquid crystal display devices, the liquid crystal glass substrate has become a bottleneck affecting the development of the liquid crystal industry with high process control requirements....
