Precise OCA (optical clear adhesive) full-laminating machine and laminated production technology thereof

Abstract

The invention provides a precise OCA (optical clear adhesive) full-laminating machine and a laminated production technology thereof. The precise OCA full-laminating machine comprises a vacuum laminating mechanism and a suction plate mechanism, wherein the vacuum laminating mechanism is respectively used for loading two products to be adsorbed; and the vacuum laminating mechanism can be attached and sealed with the suction plate mechanism, so as to support the processes of firstly vacuumizing inside a stitching seal cavity before laminating and then aerating light gas. Thus, the vacuum degree requirements are reduced; and the light gas automatically ascends to remove air bubbles after the attached product is exposed in an atmospheric environment even if air bubbles are generated in the laminating process due to participation of the light gas. Therefore, an extra bubble removing step is not needed by adopting the technology; an energy source can be saved; and the laminating yield of the product can be greatly improved. In addition, the laminating registration accuracy can be greatly improved and achieve the range of + / -0.02mm by increasing image sensing recognition; the registration application range is wider; multi-purpose can be achieved; and the target of reducing the cost is achieved.

Description

technical field [0001] The invention relates to a touch screen production equipment, in particular to a precision OCA full lamination machine and a lamination production process thereof.

All kinds of machines are more and more developed in the direction of further cost reduction, convenient operation, superior performance, and the ability to meet the production of medium and large...

AI Technical Summary

Problems solved by technology

[0003] The usual laminating machine is made of roller type or pressure head type lamination. Whether it is roller type lamination or pressure head type lamination, their common disadvantage is that a high vacuum environment is required for lamination. If the vacuum degree is not enough, air bubbles will be generated. , and the bubbles generated are not easy to get rid of

Furthermore, the existing laminating machine adopts a mechanical positioning method during lamination, and poor alignment accuracy easily leads to lamination failure.
