Frame sealing glue coating device, work method thereof and frame sealing glue coating equipment

Abstract

The invention discloses a frame sealing glue coating device, a work method thereof and frame sealing glue coating equipment. The frame sealing glue coating device comprises a spray nozzle, the spray nozzle comprises an air inlet portion and a glue outlet portion, a switch plate is arranged below the glue outlet portion, the switch plate comprises a plate body, one end of the plate body is provided with a through hole, and a spitting portion is arranged on the side, opposite to the glue outlet potion, of the plate body and arranged at the position corresponding to the through hole; the plate body can conduct horizontal movement between a first state and a second state, in particular, when the plate body is in the first state, the glue output position is opposite to the through hole, and the frame sealing glue in the spray nozzle is spitted out through the spitting portion; when the plate body is in the second state, the plate body totally block the glue outlet portion so as to prevent the frame sealing glue in the spray nozzle from being spitted out. According to the technical scheme, the switch plate is arranged below the glue outlet portion of the spray nozzle, so that the glue splitting state of the glue outlet portion can be controlled timely and accurately, and accordingly the coating quality can be effectively improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a frame sealing glue coating device, a working method thereof, and a frame sealing glue coating equipment. Background technique [0002] A liquid crystal display panel generally includes an array substrate and a box-mounted substrate that are arranged opposite to each other. Before the array substrate and the box-mounted substrate are boxed, a sealant coating device needs to be used to apply a sealant on one side of the substrate to seal the liquid crystal. seal. [0003] figure 1 It is a structural schematic diagram of a frame sealing glue coating device in the prior art, such as figure 1 As shown, it includes: a nozzle 1 , an air intake unit 5 and a solenoid valve 4 , and the air intake unit 5 is connected to the air intake part 3 of the nozzle 1 through the solenoid valve 4 . When working, there is a certain amount of sealant (not shown) stored in the nozzle 1. At this tim...
