Abstract
A friction alignment device for a curved substrate, which includes: a rotating sleeve, a friction alignment roller, a carrying device and a movable platform. The friction alignment roller is connected to the rotating sleeve and has a curved plane. The carrying device adsorbs a curved substrate to a carrying curved surface. Among them, the carrying device adjusts a height so that the curved plane and the curved substrate are in contact with an alignment pressure, and the rotating sleeve is used to rub the curved substrate, and at the same time, the movable platform performs a displacement of the height, and the curved substrate undergoes three-dimensional friction alignment.
