Apparatus and method for continuous manufacturing of optical display devices

Abstract

The invention provides an apparatus and method for continuously manufacturing an optical display device. The provided apparatus and method can laminate an optical functional film and a rectangular panel more precisely. The apparatus comprises a film detection unit, which is used to detect the gesture of a sheet like optical functional film; a panel detection unit, which is used to detect the gesture of a rectangular panel; a derivation quantity determination unit, which is used to determine the derivation quantity between the gesture of the sheet like optical functional film and the gesture of the rectangular panel; and a moving unit, which is used to align the gesture of the rectangular panel and the sheet like optical functional film based on the derivation quantity. Furthermore, the moving unit can move the rectangular panel so that the prescribed range of the front part of the rectangular panel is arranged between a pair of lamination rollers. The state of the rectangular panel is fixed, when the prescribed range is protruded and the moving unit moves the rectangular panel.

Description

technical field [0001] The present invention relates to the manufacture of an optical display device, and more specifically, to an optical display device capable of bonding a rectangular panel to an optical functional film by moving it in a fixed state from being aligned with an optical functional film to moving to a bonding device. Continuous manufacturing apparatus and method. Background technique [0002] In the manufacture of optical display devices such as liquid crystal display devices, the individual lamination method has been used in the past, that is, a large number of optical functional film sheets that have been pre-cut from a strip-shaped optical functional film outside the manufacturing process of the optical display device. Introduced into the manufacturing process of the optical display device, and sequentially bonded to the rectangular panel introduced separately in the manufacturing process. Compared with such an individual bonding method, the following met...

Therefore, in the device of Patent Document 2, similarly, the attitude of the optical display member corrected to be aligned with the attitude of the optical member may be caused by a gap between the transport unit and the conveyance unit that occurs during the period from when the suction is released to when it is pinched by the nip roller. Changes in the conveying process due to contact friction or uneven conveying speed

[0008] In addition, in the case of a device structure in which the rectangular panel is returned to the conveying unit after posture detection and correction, and is sent to the laminating position on multiple small-diameter rollers, the front of the pair of laminating rollers from the alignment unit to the laminating unit Many small-diameter rollers have been arranged in a straight line, so a certain amount of space is required for this arrangement, and the layout of the alignment unit and the bonding unit has to be designed in line

Therefore, in the RTP system in recent years, in terms of the improvement of production efficiency per unit installation area, the miniaturization of the device and the degree of freedom of device design required by the degree of freedom in the replacement of some components of the existing device, this Existing installations of structures are limited
