Scraper type jelly glue full binding method

Abstract

The invention relates to the technical field of liquid crystal display, in particular to a scraper type jelly glue full binding method. The scraper type jelly glue full binding method includes the steps that a mold is combined with binding faces, the mold is provided with a hollowed-out region, the hollowed-out region of the mold is opposite to the liquid optical cement coating range positions of the binding faces, and the shape and the size of the hollowed-out region are the same as those of the liquid optical cement coating ranges of the binding faces. The whole hollowed-out region of the mold is fully coated with liquid optical cement in a face coating mode; the whole gluing face is precured through an area source, and the liquid optical cement is converted to be in a jelly state; a scraper is tightly attached to the surface of the mold, and redundant glue is horizontally scraped away at a constant speed; the mold is removed; glue is fully bound to the other binding face, and the glue is cured after being bound to the other binding face. By the adoption of the method, the poor phenomena of glue overflow, glue shortage, bubbles and the like after full binding operation are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a scraper type jelly glue full lamination method when liquid optical glue is used for full lamination among liquid crystal screens, glass and films. Background technique [0002] In the prior art, when liquid optical glue is used for full lamination among liquid crystal screens, glass, and films, a dispensing needle is used to draw graphics on one of the laminating surfaces. Three aspects are used to control glue overflow, glue shortage, and bubble defects. Due to uneven glue application or spreading, flatness of the bonding surface, and equipment precision, such undesirable phenomena as glue overflow, glue shortage, and bubbles cannot be avoided. In order to control problems such as glue overflow, follow-up equipment manufacturers pre-applied a circle of dam-building glue around the bonding surface while controlling the amount of glue to ensure no glue overflow.

[0002] In the prior art, when liquid optical glue is used for full lamination among liquid crystal screens, glass, and films, a dispensing needle is used to draw graphics on one of the laminating surfaces. Three aspects to control glue overflow, glue shortage, and bad air bubbles. Due to uneven glue application or spreading, flatness of the bonding surface and equipment accuracy, such undesirable phenomena as glue overflow, glue shortage, and air bubbles cannot be avoided.

In order to control problems such as glue overflow, follow-up equipment manufacturers pre-applied a circle of dam-building glue around the bonding surface while controlling the amount of glue to ensure no glue overflow. However, because the dam-building glue is pre-cured in advance and has a certain height, During the subsequent bonding process, the gas in the bonding gap cannot be completely removed, resulting in bonding air bubbles
