A full bonding device and method suitable for large-size touch screen g+g

Abstract

A fully laminating device and method suitable for large-size touch screens (G+G). The device is equipped with a dispensing module and a machine frame, wherein the dispensing module consists of a limit support mechanism, a dispensing device, and a displacement device. The displacement device is arranged horizontally on the upper end of the machine frame, and there is a long strip-shaped slot horizontally on it. The dispensing device is arranged on the slot and can slide horizontally along the slot. The dispensing device is equipped with a dispensing needle. ; The limit support mechanism is set in the middle of the machine frame and can be controlled to translate back and forth on the machine frame. There is a horizontal support surface on it. The horizontal support surface is located below the dispensing device and is in contact with the dispensing needle. Correspondingly, this design is beneficial to achieve the preset dispensing process through reasonable automatic control for the glass cover plate that needs dispensing.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a fully laminating device and method suitable for large-size touch screens G+G. Background technique [0002] In the past, touch panels were mostly used in the field of mobile phones, notebook computers or tablet computers. The size of the screens was small and could be produced by automatic laminating devices. However, with the extension of touch panel application scenarios, the size of touch panels is When the size of the touch panel exceeds 21 inches (including 21 inches, 21 inches and above are defined as large sizes), the traditional automatic laminating device cannot meet the needs of production, and can only be realized by hand. The lamination between the glass cover plates has low production efficiency, high labor intensity for workers, and the lamination accuracy cannot be guaranteed, resulting in a low yield rate. [0003] And existing small and medium size scr...

[0002] In the past, touch panels were mostly used in the field of mobile phones, notebook computers or tablet computers. The size of the screens was small and could be produced by automatic laminating devices. However, with the extension of touch panel application scenarios, the size of touch panels is When the size of the touch panel exceeds 21 inches (including 21 inches, 21 inches and above are defined as large sizes), the traditional automatic laminating device cannot meet the needs of production, and can only be realized by hand.

[0003] And existing small and medium size screens, such as figure 1 As shown, the glue dispensing paths cross, and the glue at the intersection 1' is easy to accumulate. When combining, the glue is in contact with the surface of the glass cover, and the accumulated glue is easy to generate air bubbles. However, the amount of glue and air bubbles are easier to control because of small and medium-sized screens. , if it is a large screen, it is more difficult to control its bubbles
