Example Embodiment

[0014] The present invention will be further described below with reference to the drawings and embodiments. It can be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for ease of description, the drawings only show a part but not all of the content related to the present invention.

[0015] Please refer to figure 1 As shown, in this embodiment, the glue with automatic initial curing function is named glue a, the glue for laminating is named glue b, 101 is glue a dispensing area, 102 is glue b dispensing area, 103 is functional glass Sheet, 104 is a flexible circuit board.

[0016] Such as figure 2 As shown, the cofferdam type water glue bonding process in this embodiment specifically includes the following steps:

[0017] Step S201: Place the bound functional glass sheet 103 on the laminating platform, set the dispensing amount, and evenly dot the ...

Abstract

The invention discloses a cofferdam type glue sticking process. The cofferdam type glue sticking process comprises the following steps: A, placing a bound functional glass sheet on a sticking platform and setting a dispensing amount, and uniformly dispensing glue with an automatic primary-curing function at the periphery of the functional glass sheet; B, standing the cofferdam type functional glass sheet of the step A for 3-5 minutes and setting the dispensing amount, dispensing glue for sticking at the center of the functional glass sheet; and C, sticking a glass cover plate with the functional glass sheet and then fully curing the leveled glue. Compared with a traditional glue sticking process, one layer of the glue which can be automatically and primarily cured and is not completely cured when being not treated is dispensed at the periphery of a sticking outer frame, and then the glue dispensing, sticking and curing are carried out, so that the glue can be effectively prevented from being overflowed, the overflowing difficulty is overcome effectively and the sticking yield is improved.

Description

technical field [0001] The invention relates to the field of water-glue bonding technology, in particular to a cofferdam-type water-glue bonding technology. Background technique [0002] As the touch screen industry has more and more demands for G+G (glass cover plate + glass functional sheet) structure, due to the low bonding efficiency and finished product yield of solid optical glue, water glue is bound to become the G+G structure bonding The mainstream trend, the water-glue bonding process will be widely used in the back-end bonding of G+G capacitive screens. However, the traditional water-glue bonding has the following disadvantages: after the glue is applied, a part of the glue will overflow the bonding area during the leveling process, and even overflow to the front of the glass cover. After being cured by UV (ultraviolet) light It cannot be removed, which will affect the bonding efficiency and cause pollution to the bonding machine. Contents of the invention [0...
