Abstract
The invention discloses a control method and device for adjusting the shape of a glass substrate. The control method comprises steps as follows: detecting an infrared signal radiated by the glass substrate during production; converting the detected infrared signal into an electric signal; judging whether the shape of the glass substrate needs to be adjusted according to the converted electric signal; adjusting the shape of the glass substrate by controlling the differential pressure of the front and rear surfaces of the glass substrate under the condition that the shape of the glass substrate needs to be adjusted. Accordingly, the shape of the glass substrate can be detected during production, whether the shape of the glass substrate needs to be adjusted can be judged according to a judgement result, the shape of the glass substrate can be controlled to be adjusted when the shape of the glass substrate needs to be adjusted, the problem of relatively high and uneven stress in glass due to changes of the glass shape can be solved, and the yield of the glass substrate is improved.
Description
technical field [0001] The invention relates to the field of production of liquid crystal glass substrates, in particular to a control method and device for adjusting the shape of a glass substrate. Background technique [0002] The liquid crystal glass substrate is an important part of the liquid crystal display. The liquid crystal panel display technology has strict requirements on the stress of the glass substrate used. If the stress of the glass substrate does not meet the requirements, the liquid crystal panel is prone to bursting in the downstream manufacturing process. , deformation and other issues. At present, glass substrates for liquid crystal glass substrates are mainly produced by the overflow down-draw method. This method is widely used and the technology is relatively mature. However, this method has high requirements for the control of the production process and production environment. The high and uneven internal stress of the glass caused by the change res...
