Glue dispensing method of R corner of screen and manufacturing method of display device

Abstract

The invention discloses a glue dispensing method of an R corner of a screen and relates to the technical field of shading glue spraying. The glue dispensing method comprises the following steps of S1,a glue dispensing device moves to a first position in a non-spraying state and reaches at a preset speed; S2, the glue dispensing device rotates to the first end of the R corner of the screen at thepreset speed uniformly and sprays the shading glue to form a first glue section; S3, the glue dispensing device decelerates to the side, far away from the R corner of the screen, of the first end in ashading glue non-spraying state till the speed is zero; S4, the glue dispensing device moves to the first position in the non-spraying state and reaches at the preset speed; and S5, the glue dispensing device rotates reversely to the other end of the R corner of the screen at a uniform preset sped in a first rotating direction and spraying the shading glue to form a second glue section. The gluedispensing device moves at the uniform speed when the first and second glue sections are formed, so that it is ensured that the shading glue on the R corner of the screen is uniform in thickness and the laminating yield of the screen and a screen housing is improved.

Description

technical field [0001] The invention relates to the field of shading glue spraying, in particular to a method for dispensing glue at the R corner of a screen and a method for manufacturing a display device. Background technique [0002] With more and more types of display devices, users have higher and higher requirements on the aesthetic appearance of the display devices, and the aesthetic appearance of the display devices largely depends on the shape of the screen. The R corner of the screen refers to the rounded corners of the four corners of the screen. The size of the R corner of the screen affects the aesthetics of the screen. A screen with a larger R corner helps to improve the aesthetics of the display device, thereby enhancing the attractiveness of the display device to users. . [0003] In order to prevent the visual effect of the display device from being reduced due to light leakage from the screen, the outer peripheral surface of the R corner of the screen need...

Problems solved by technology

When spraying starts, the dispensing device first accelerates from the beginning of the R angle of the screen; then, the dispensing device moves at a constant speed in the middle of the screen R angle; finally, at the end of spraying, the dispensing device decelerates relative to the screen Movement, so that the dispensing device stops at the terminal end of the R angle of the screen. Since the amount of shading glue sprayed by the dispensing device per second is constant, the glue section sprayed by the dispensing device during the acceleration process and deceleration process is too high. Thick, resulting in uneven thickness of the rubber section on the R corner of the screen, resulting in low bonding yield between the screen and the screen shell

[0005] Therefore, there is an urgent need for a dispensing method for the R corner of the screen and a method for manufacturing a display device to solve the problem of uneven thickness of the glue section on the R corner of the screen.
