Full lamination device and method suitable for large size touch screen (G+G)

Abstract

The invention discloses a full lamination device and method suitable for a large size touch screen (G+G). The device is provided with a glue dispensing module and a machine platform framework, whereinthe glue dispensing module is composed of a limiting supporting mechanism, a glue dispensing device and a displacement device, the displacement device is horizontally arranged at the upper end of themachine platform framework, a strip-shaped penetrating groove is horizontally formed in the displacement device, the glue dispensing device is arranged on the penetrating groove and can horizontallyslide along the penetrating groove, and a glue dispensing needle is arranged on the glue dispensing device; the limiting supporting mechanism is arranged in the middle of the machine platform framework and can be controlled to move back and forth horizontally on the machine platform framework, a horizontal supporting plane is arranged on the limiting supporting mechanism, and the horizontal supporting plane is located below the glue dispensing device and corresponds to the glue dispensing needle; the design helps to achieve a preset glue dispensing process through reasonable automatic controlling for a glass cover plate on which glue dispensing needs to be conducted.

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 s...

[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, and the lamination accuracy cannot be guaranteed, resulting in low yield

[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
