Abstract

The invention provides an adhesive pressing device which comprises a cylinder, a cylinder cover and an air inlet pipe communicated with a compressed air source. The cylinder and the cylinder cover form a space for storing a frame adhesive. An inlet is formed in the cylinder cover. The air inlet pipe stretches into the upper portion inside the cylinder from the inlet. An outlet is formed in the bottom of the cylinder. The adhesive pressing device further comprises a piston arranged inside the cylinder. The piston can be pushed by the compressed air source to move on the inner wall of the cylinder in an attached mode so as to press out the frame adhesive stored inside the adhesive pressing device. When the frame adhesive in the device needs to be pressed out, the phenomenon that the frame adhesive close to the inner wall of the device is hung to the wall can be avoided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a glue pressing device. Background technique [0002] In recent years, liquid crystal display (Liquid Crystal Display, LCD) technology has been rapidly popularized due to its unique advantages of low power consumption, low radiation, light weight and convenience. Among them, the thin film transistor liquid crystal display (Thin Film Transistor-Liquid Crystal Display, TFT-LCD) uses thin film transistors (Thin Film Transistor, TFT) to generate voltage to control the direction of liquid crystal molecules to achieve screen display, TFT-LCD panel with its The advantages of fast response speed and large viewing angle have been widely used in electronic devices such as mobile phones. [0003] TFT-LCD panels usually include a TFT array substrate and a color filter substrate oppositely arranged, and a liquid crystal layer and a frame glue arranged between the two substrate...
