Description

TECHNICAL FIELD

[0002] In the production and processing of liquid crystal glass, the transmission and positioning accuracy of the glass substrate are crucial to the smooth production process. Traditional mechanical transmission methods, such as belt transmission or roller transmission, will bring certain mechanical contact, which may cause scratches or micro-cracks on the surface of the glass substrate.

[0003] Therefore, air floatation transmission technology is gradually applied. Through the uniform airflow of the air floatation platform, the glass substrate can be suspended on the surface of the platform, avoiding direct contact with the transmission surface, thereby significantly reducing the risk of surface damage. However, in many automated production lines, mechanical arms are usually used to pick up glass substrates for subsequent processing or assembly operations. Such procedures require the glass substrate to not only be stably suspended during air floatation transmission, but also to be precisely positioned at a specific location so that the mechanical arm can efficiently and accurately complete the picking action.
