Abstract

The invention discloses a frame sealing glue coating device for shortening the process time of coating frame sealing glue, improving the coating efficiency and improving the thickness uniformity of coating the frame sealing glue. The frame sealing glue coating device comprises a storage cavity, a nozzle, a connecting guide pipe and a power driving component, wherein the nozzle comprises a nozzle cavity and a nozzle opening; the nozzle opening is positioned below the nozzle cavity and is matched with the shape of a frame sealing glue coating zone of a baseplate; the connecting guide pipe is used for communicating a storage cavity and the nozzle cavity; the power driving component is used for squeezing frame sealing glue in the storage cavity to the nozzle cavity through the connecting guide pipe and is squeezed out through the nozzle opening. When the power driving component drives the frame sealing glue to be squeezed out from the nozzle opening, the frame sealing glue can be integrally coated to the frame sealing glue coating zone of the baseplate, so that the process time of coating the frame sealing glue is greatly shortened and the coating efficiency is improved by the adoption of the solution. Furthermore, owing to integrated coating of the frame sealing glue, a coating start end and a coating stop end are cancelled, so that coating overlap can be avoided, and thus the thickness uniformity of coating the frame sealing glue is improved.

Description

technical field [0001] The invention relates to the technical field of manufacturing display devices, in particular to a frame sealing glue coating device. Background technique [0002] The liquid crystal panel of Thin Film Transistor Liquid Crystal Display (TFT-LCD for short) mainly includes: a color filter substrate and an array substrate arranged in opposite boxes, and a liquid crystal layer filled between the color filter substrate and the array substrate. [0003] The process of setting the pre-prepared color filter substrate and the array substrate in the box is called the "box matching process". The peripheral area is evenly coated with sealant; after the above steps are completed, the two substrates are boxed together, and the sealant is cured to achieve the lamination of the two substrates. [0004] Such as figure 1 As shown, it is a schematic structural diagram of an existing sealant coating device, including: a storage chamber 2 for storing the sealant; an air d...
