A liquid crystal touch screen full lamination equipment

Abstract

The invention discloses a full-lamination device of an LCD (liquid crystal display) touch screen. The device comprises a turnover mechanism including at least one shelving table, a triaxial-surface glue mechanism (1) arranged above the shelving table, an alignment adjusting system comprising at least one base plate (3) which moves up and down through a linear guide, a triaxial dispensing mechanism (2) arranged above the base plate (3), and a curing mechanism adjacent to the triaxial dispensing mechanism (2), wherein the glue output end of the triaxial-surface glue mechanism (1) is of a single-row pinhole structure, the glue output end of the triaxial dispensing mechanism (2) is of a single pinhole structure, a light source of the curing mechanism is an UV point light source, and the triaxial dispensing mechanism (2) is connected with the curing mechanism through a triaxial manipulator. The full-lamination device of the LCD touch screen provided by the invention is capable of realizing the full automation during the lamination process of the LCD touch screen.

Description

technical field [0001] The invention relates to a liquid crystal touch screen full bonding device, in particular to a fully automatic liquid crystal touch screen full bonding device. Background technique [0002] The liquid crystal touch screen can be roughly divided into three parts in terms of structure: protective glass, touch screen and liquid crystal display. The bonding process of LCD touch screen is usually divided into two steps: firstly, the protective glass is bonded to the touch screen, and then the touch screen is bonded to the display screen; the bonding method is divided into two methods: full bonding and frame bonding. [0003] The so-called frame sticker is also called word glue bonding, that is, the four sides of the touch screen and the display screen are simply fixed with double-sided tape. This is also the bonding method used by most display screens at present. Its advantages lie in simple process and low cost. , but because there is an air layer between...

Problems solved by technology

[0005] Although the advantages of full lamination are huge, the yield rate is relatively low. The consumption and scrapping of the surface glass and even the panel in the lamination process due to poor yield will inevitably lead to an increase in cost. Therefore, defoaming and lamination The control of the yield rate will become a more important factor than the cost of materials. By using automated equipment for program control and real-time monitoring, replacing manual operations will effectively control the bonding yield rate.
