AI Technical Summary

Technical Problem

Existing adhesive application equipment struggles to achieve narrow-bezel adhesive application, and the large-diameter syringe results in a small contact area between the sealing frame and the upper substrate, increasing the risk of leakage and costs.

Method used

The first and second adhesive application components are used to apply the frame adhesive and the support component respectively, forming an adhesive layer and a frame adhesive layer. The support component is pressed into the adhesive layer to form the frame adhesive layer. The inner diameter of the second nozzle is larger than that of the first nozzle. The support component is coated through a filter screen and a vent hole to reduce the amount of adhesive and improve the sealing performance.

Benefits of technology

It achieves narrow-bezel adhesive application, reduces adhesive usage, improves sealing and bonding strength, reduces the risk of leakage, and lowers costs.

Abstract

This utility model relates to the field of display processing technology, and discloses a glue application device and a display device. The glue application device includes a first glue application component and a second glue application component. The first glue application component includes a first cavity and a first nozzle communicating with the first cavity. The first cavity can hold frame glue, and the frame glue can be applied to the area to be glued via the first nozzle to form an adhesive layer. The second glue application component includes a second cavity and a second nozzle communicating with the second cavity. The inner diameter of the second nozzle is larger than the inner diameter of the first nozzle. The second cavity can hold a support member, and the support member can be applied to the adhesive layer via the second nozzle and pressed into the adhesive layer to form an adhesive frame layer. The glue application device of this utility model can achieve glue application to narrow bezels, resulting in better sealing and less glue consumption.
