A glass glue printing device

Abstract

The invention relates to the field of display technology, and discloses a glass glue printing device. The glass glue printing device includes: a storage box with an open top, the bottom plate of the storage box is provided with a plurality of glue outlets, and each glue outlet is provided with A colloid conveying tube; a pressing plate located in the holding box and slidingly matched with the side wall of the holding box, the pressing plate is opposite to the bottom plate of the holding box, so as to cooperate with the bottom plate and the side wall of the holding box to form a cavity; each colloid delivering pipe passes through the outlet The glue port communicates with the cavity; the printing plate, the printing plate is provided with a printing unit corresponding to the glue outlet one by one, and each printing unit includes an annular printing groove whose opening is away from the holding box, and the side wall of the printing groove has air guide holes, each A pair of glue outlets corresponding to each other communicate with the printing groove of the printing unit through the glue delivery pipe. By changing the structure of the glass glue printing device, it is not only beneficial to accurately control the printing precision of the glass glue, but also can eliminate the phenomenon of glass glue offset and edge burrs.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a glass glue printing device. Background technique [0002] Currently, one of the encapsulation methods adopted by OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display devices is glass glue encapsulation, and the glass glue is printed on the cover glass by screen printing. [0003] However, this technology is difficult to accurately control the printing accuracy of the glass glue, that is, the height and width of the glass; at the same time, the glass will appear offset and edge burrs after printing, resulting in the back-end laser sintering of the cover glass and the array substrate after lamination During the process, the effective sintering area of ​​the glass is reduced, and the ability to isolate water and oxygen is reduced, which seriously affects the performance and service life of the OLED device.
