[0004] However, if Figure 7 As shown, the peeling member 741 is used to fold the carrier film 712 inside the carrier film 712 to peel off the carrier film 712 while sandwiching the peeled polarizing film 714 with a pair of sticking members (750a, 750b). In the case of a method of pasting the peeled polarizing film sheet 714 and the optical unit 740 together with the optical unit 740, for example, sticking air bubbles are generated in the pasted optical unit 740 due to the vibration of the film sheet 714 when pasted. and results in poor image display, so an improvement is expected

Embodiment approach 1

[0065] The continuous manufacturing system of the optical display panel according to the present embodiment includes a carrier film conveying unit for conveying the carrier film of the film sheet to which the polarizing film is attached via an adhesive, and a peeling unit for utilizing the The top end is used to fold back the carrier film conveyed by the above-mentioned carrier film conveying part to the inside, so as to peel off the film sheet together with the adhesive from the carrier film; A carrier film winding; a sticking part for forming an optical display panel by sticking the film sheet peeled from the carrier film by the above-mentioned peeling part on the optical unit with an adhesive while conveying the optical unit; and a speed control part It is used to control the conveyance speed of the said winding part and the said sticking part.

[0066]Further, the speed control unit performs setting and control such that the sticking speed of the sticking process by the st...

Embodiment approach 2

[0102] In Embodiment 2, a configuration different from that of Embodiment 1 described above will be described. The 1st carrier film conveying part 101 of Embodiment 2 has the downstream side film supply part 95 instead of the upstream side film supply part 90.

[0103] The downstream-side film supply part 95 is constituted by a feed roller, and is arranged at a position on the conveyance downstream side from the first peeling part 40 and on the conveyance upstream side from the first take-up part 60 (refer to Figure 4B ), the feed roller includes: a first roller 95a driven by an unillustrated motor; and a second roller 95b arranged opposite to the first roller 95a and driven by an unillustrated biasing member (for example, A compression spring, a leaf spring, etc.) are pressed toward the 1st roller 95a. The second roller 95b is driven by rotating the first carrier film 12 (the first carrier film 12 after peeling the film sheet 13) between the first roller 95a and the second ...

Embodiment approach 3

[0107] The third embodiment is configured to include both the upstream-side film supply part 90 of the above-described first embodiment and the downstream-side film supply part 95 of the second embodiment. The conveyance speed (Vs(t)) of the carrier film is controlled by both the upstream side film supply part 90 and the downstream side film supply part 95 . By arranging the film supply part (feed roller) on both upstream and downstream (upstream and downstream bounded by the first peeling part 40 ), the carrier film can be conveyed while applying tension to the carrier film. For example, tension can be applied to the carrier film between the upstream side and the downstream side by making the downstream supply speed (conveyance speed) faster than the upstream supply speed (conveyance speed).

Abstract

A method for continuously manufacturing an optical display panel includes a velocity control step includes setting a bonding velocity and a carrier film feed velocity in such a manner that during a period from the start of the bonding of the sheet piece to the end of the bonding, the bonding velocity is higher than the carrier film feed velocity is fed and in such a manner that slack formed in the sheet piece is eliminated between the bonding position and the front end of the peeling unit; and performing control in such a manner that during a period from the start of the bonding to the end of the bonding, the distance (L) is longer than the distance (Ls), while the bonding velocity in the bonding step is higher than the velocity at which the carrier film is fed.

Description

technical field [0001] The present invention relates to a continuous manufacturing method of an optical display panel and a continuous manufacturing system of the optical display panel for forming an optical display panel by pasting a film of a polarizing film peeled from a carrier film with an adhesive to an optical unit. Background technique [0002] A method is known as follows: using the tip of the peeling member to fold back the carrier film of the film sheet with the polarizing film by means of an adhesive, thereby peeling the film sheet of the polarizing film from the carrier film together with the adhesive, And the film piece of the peeled polarizing film is stuck on an optical unit with an adhesive (patent document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2004-361741 [0004] However, if Figure 7 As shown, in order to peel the carrier film 712 by using the peeling member 741 to fold the carrier film 712 back to the inside of the carrier film 7...
