Embodiment Construction

[0023] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

[0024] An adhesive film peeling device 1 according to an embodiment of the present invention is a device for peeling a polarizing plate 4 attached to a glass plate 3 as an adherend constituting a liquid crystal panel 2 from a glass plate 3. Adhesive film. This stripping device 1 has the 1st guide part 5 as guide body (the 1st guide body), and the 2nd guide part 6 as guide body (the 2nd guide body), between the 1st, the 2nd guide part 5,6 Mounting surfaces 5 a and 6 a on which the liquid crystal panel 2 is mounted are formed on the surface. On the back side of the surface on which the placement surfaces 5a, 6a are formed on the first and second guide parts 5, 6, a take-up roller 7 is arranged for peeling the polarizing plate 4 from the glass plate 3. Pull the stripped body in the direction. A gap 8 is formed between the first guide part 5 and the second guide part ...

Abstract

The invention provides an adhesive-film exfoliating device that can restrain bending stress acting on adhesive body in case of exfoliating adhesive-film from adhesive body and pulling adhesive-film, and can prevent adhesive body damage caused by over large bending stress. The adhesive-film exfoliating device includes: guide tables 5, 6 having flat mount surfaces 5a, 6a having adhesive body 3 carried with an adhesive film 4; a take-up roller 7 on the backside of the flat mount surfaces 5a, 6a configured on the guide tables 5, 6, the adhesive film 4 is pulled in direction exfoliated from adhesive body; and a slit 8 arranged between the guide tables 5, 6 to allow a passage of one adhesive film 4 exfoliated from the adhesive body 3. The slit 8 is formed with a breadth less than 5 mm.

Description

technical field [0001] The present invention relates to an adhesive film peeling device and a liquid crystal panel manufacturing method, in particular to an adhesive film peeling device used when peeling a polarizing plate as an adhesive film attached to a glass plate of a liquid crystal panel, And the manufacturing method of the liquid crystal panel which has the peeling process of an adhesive film. Background technique [0002] The liquid crystal panel is constituted by bonding two glass plates, sealing liquid crystal between the two glass plates, and bonding a polarizing plate to the outer surface of each glass plate. [0003] When defects such as scratches or stains are found on the polarizing plate through the visual inspection and lighting inspection of the liquid crystal panel, the polarizing plate in which the defect was found is peeled off from the glass plate, and a new polarizing plate with no defects is attached again. onto the glass plate. [0004] As an adhes...
