Description

Technical Field

[0001] The present application relates to the field of liquid crystal display screen processing, and in particular, to a glue dispensing device for processing liquid crystal display screens. Background Art

[0002] Liquid crystal displays have very low power consumption, so they are very popular among users and are suitable for use in electronic devices. Its main principle is to use electric current to stimulate liquid crystal molecules to produce points, lines, and surfaces to cooperate with the back light tubes to form a picture. During the production process, liquid crystal displays need to be coated with glue to facilitate the next production process.

[0003] Announcement No. CN 216655164 U discloses a dispensing device for liquid crystal display production. The spacing between two rectangular rings of the slider can be adjusted by rotating the adjusting screw, and the distance between the two rectangular rings can be directly read by the scale above the crossbar, which facilitates the adjustment of the spacing between the dispensing machines at the bottom of the two rectangular rings. The positions of the two rectangular rings can be fixed by tightening the rubber bolts, thereby achieving the effect of fixing the positions of the two dispensing machines, so that the dispensing mechanism can dispense glue on liquid crystal display screens of different sizes.

[0004] However, there are some defects in the above scheme: two dispensing machines with adjustable spacing are set in the above scheme, but the display screen placed directly on the lifting plate is prone to offset and is not easy to align. After dispensing the two sides, it is necessary to manually rotate the other two sides horizontally to adjust them to the bottom of the dispensing machine. Such operation is really troublesome and inefficient. Utility Model Content
