The invention is suitable for the technical field of liquid crystal display, and provides an air exhaust control method and system of a vacuum laminating machine and the vacuum laminating machine. The air exhaust control method of the vacuum laminating machine comprises the steps that when it is detected that the air pressure in a vacuum cavity reaches first air pressure, fine alignment is started, and first air exhaust equipment is controlled to be closed, when it is detected that fine alignment is completed, the first air exhaust equipment is controlled to start air exhaust work, and when it is detected that the air pressure in the vacuum cavity reaches second air pressure, the second air exhaust equipment is controlled to start air exhaust work, and it is judged that the vacuum laminating work is finished when detecting that the air pressure in the vacuum cavity reaches third air pressure. In the fine alignment process, the vacuum cavity is in a low vacuum state, the liquid crystal evaporation rate is reduced, the problems of uneven brightness, bubbles and the like caused by liquid crystal evaporation are solved, and therefore the attaching precision and quality of the display device are improved.
Description
technical field [0001] The application belongs to the technical field of liquid crystal display, and in particular relates to a method and system for controlling air extraction of a vacuum laminating machine and a vacuum laminating machine. Background technique [0002] With the development of the electronic product market, electronic display devices are used in various fields, such as mobile phones, tablet computers, advertising screens and other devices have gradually become the most important social devices for workers in various industries. [0003] In the production process of liquid crystal display devices, how to bond the substrates with a vacuum laminating machine is a very important part. The existing bonding methods may cause low bonding accuracy to varying degrees, resulting in uneven brightness of the display device. Problems such as uniformity and bubbles reduce the quality of the product. Contents of the invention [0004] The purpose of this application is ...
