[0006] The beneficial effects of the present invention are: the present invention connects the spring plate on both sides of the LCD glass substrate, so that in the process of pressing and baking, the uneven pressure generated when the air pressure passes through the air bag will pass through the spring plate. Strong, not easy to deform, so the spring plate can improve the situation of uneven pressure, and transmit uniform pressure to the LCD glass substrate, the setting of the spacer sheet is to prevent the LCD glass from being damaged due to the direct contact between the spring plate and the LCD glass substrate Substrate, the structure of the present invention is simple, is suitable for mass production, and can obtain the LCD glass substrate of uniform thickness, and obviously improves the good product rate of finished LCD

Embodiment Construction
[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0016] refer to figure 1 with figure 2 , LCD glass substrate press baking device of the present invention, wherein, comprises air bag 1, spring board 2, press grill 3 and interlayer sheet 4. The airbag 1 can be made of silicone skin. The airbag 1 is installed in the grill 3 and connected to the spring plate 2. In addition, in order to prevent the rigid spring plate 2 from directly contacting the LCD glass substrate 5, the spring plate 2 and the LCD glass substrate 5 are interposed with a spacer sheet 4, and the spacer sheet 4 can be made of a slightly elastic material, such as paper, cotton fiber, rubber, metal, ceramics, etc.
[0017] The spring plate 2 includes an upper plate 21 , a lower plate 22 and a spring 23 . Spring 23 is a plurality of, and a plurality of springs 23 uniform ends are connected with upper plate 21, and the other end is connected wi...

The invention discloses an LCD glass substrate pressing and baking device which comprises an air bag, spring plates, a pressing and baking frame and an interlayer, wherein the air bag is installed in the pressing and baking frame and is connected with the spring plates; the interlayer is cushioned between the spring plate and the LCD glass substrate. By connecting the spring plates to two sides of the LCD glass substrate, during the pressing and baking process, non-uniform air pressure generated when air pressure passes through the air bag passes through the spring plates and is improved by the spring plates due to high rigidity and low possibility of deformation of the spring plates, and then uniform pressure is conducted into the LCD glass substrate; the interlayer is adopted to prevent the LCD glass substrate from being damaged due to direct contact of the spring plates and the LCD glass substrate. The LCD glass substrate pressing and baking device disclosed by the invention is simple in structure, and suitable for large-scale production, an LCD glass substrate with uniform thickness can be obtained, and the yield of finished product LCDs can be improved.
Description
technical field [0001] The invention relates to the field of LCD processing, in particular to an LCD glass substrate pressing and baking device. Background technique [0002] The glass substrate of LCD (Liquid Crystal Display, liquid crystal display) needs to be pressed and baked during the manufacturing process, so that the upper and lower glass substrates of the LCD can be fixed at a certain distance. The key of the press-baking process is that the LCD glass substrate can be fully pressed as required without damaging the LCD glass substrate, and the thickness of the obtained LCD glass substrate is as uniform as possible. [0003] Therefore, in order to protect the LCD glass substrate and obtain a better press-baking effect, commonly used LCD press-baking equipment usually uses an airbag between the press plate and the LCD glass substrate to press and bake it. However, due to the thickness of the LCD glass substrate The precision requirements are very high, and the airbag ...
