Description

[0002] With the rapid development of the display industry, electronic glass is gradually evolving towards large size and thinness. Therefore, flexible glass shows broad application prospects in the fields of flexible display, ITO conductive film glass substrate, OLED lighting and flexible thin-film solar cell due to its unique flexibility and stable physical and chemical properties.

[0003] In the prior art, an online thickness detection device is usually used to detect the thickness of flexible glass in the conveying process. However, since the measurement accuracy is as high as 3 microns or more and the sampling speed is fast, the flexible glass is prone to bending in the continuous conveying process due to its own strength. Although the use of belt conveying can solve the bending problem, the direct contact between the lower surface of the glass and the belt is prone to cause reflected light, which interferes with the thickness detection, resulting in the problems of difficulty in thickness measurement and reduction of measurement accuracy. CONTENT OF THE UTILITY MODEL
