Abstract

Provided are a method and device for manufacturing an optical display device in which optical sheets are peeled sequentially and bonded to panel members, said optical film sheets being continuously supported on an elongate web-shape carrier film together with an adhesive layer. An optical display device is manufactured using a moveable peeler which is provided with bonding rollers configured to open and close vertically relative to the feed direction of the optical display device, and with a top part that can be inserted between and removed from between the opened bonding rollers. In particular, in manufacturing the optical display device, by winding an elongate web-shape carrier film in a state in which the back surface is folded back inwards by the top part of the moveable peeler and is wound around the moveable peeler, multiple optical film sheets, which are supported continuously on one surface of the carrier film through intermediary of an adhesive layer, are sequentially peeled from the carrier film together with the adhesive layer through the peeling action of the moveable peeler and are bonded, through intermediary of an adhesive layer, to one surface of a panel member through the bonding action of the closed bonding rollers.

Description

technical field

[0001] The present invention relates to a method and device for manufacturing an optical display device using a laminating roller and a movable peeling body. Close the top of the space between the rollers. In particular, the present invention relates to a method of winding up a long strip-shaped carrier film in a state where the back side is folded back inwardly at the top of the front end portion constituting the movable peeling body. , with the help of the peeling action of the movable peeling body, a plurality of optical films continuously supported on one side of the carrier film through the adhesive layer and the adhesive layer are sequentially peeled off from the carrier film, and bonded by the bonding roller Operation A method and device for manufacturing an optical display device by attaching an optical film to one surface of a panel member via an adhesive layer.

Embodiment Construction

[0064]

[0065] figure 2 It is a top view and a side view which show the whole apparatus 10 which manufactures the optical display device 6 by bonding the optical film sheet 3 and the panel member 5 at the predetermined attachment position 100. Among them, the laminating rollers 50, 51 configured to open and close in the up and down direction with respect to the conveying direction are arranged at the predetermined sticking position 100, and the movable peeling body 60 is arranged. The space 400 between the closing rolls 50 and 51 is movable between the space 400 and the work start position 200 .

[0066] Depend on image 3 It can be seen that the carrier film 2 supports the front end 31 of the optical film sheet 3 in a state wound on the movable peeling body 60, and the carrier film 2 is in a state where the back side is folded back inwardly at the top 61 constituting the front end portion of the movable peeling body 60. The state of being wound on the movable peeling bod...
