With the continuous development and progress of liquid crystal display (Liquid Crystal Display; LCD) technology, from the early small-size liquid crystal display used in electronic products such as electronic watches and electronic computers to the current application in notebook computers, color TVs and other electronic products Medium and large-sized liquid crystal displays show that liquid crystal displays are developing towards high chromaticity and large size. The problem of difficult handling of glass substrates.

For example, the length, width and thickness of the five generations of color filters are about 130 cm, 120 cm and 0.05 cm respectively. In order to avoid the bending of the color filters, the color filters are preferably placed vertically on the ground transport. The traditional way of handling is to manually move the color filter to the next working area by hand. This kind of handling method is not only limited by the height of the movers themselves, but also the working area must have enough space for the movers to work. This manual handling method has a high risk of fragmentation and poor delivery efficiency.

Therefore, how to safely and efficiently transport large substrates such as fifth-generation color filters has become a very important issue.
