Method and apparatus for manufacturing optical display device

摘要

A method for manufacturing an optical display device comprising: after completing lamination of a preceding optical film sheet to one of opposite surfaces of a preceding panel component at the predetermined laminating position, unwinding the carrier film in a state where another surface thereof folded to inside at a tip-end configuring a head portion of a peeling member and the carrier film is passed around the peeling member, and backwardly feeding a leading end of the optical film sheet supported on the carrier film to a predetermined feeding position provided at upstream of the tip-end of the peeling member.

1. A method for manufacturing an optical display device by sequentially peeling a plurality of optical film sheets together with an adhesive layer from a carrier film, the optical film sheets being continuously supported via the adhesive layer on one of opposite surfaces of a long web of the carrier film which configures an optical film laminate, and laminating the plurality of optical film sheets to one of opposite surfaces of respective ones of a plurality of panel components via the adhesive layer by using a laminating unit at a predetermined laminating position, the method comprising:
a first step of, after completing lamination of a preceding optical film sheet to one of opposite surfaces of a preceding panel component at the predetermined laminating position, unwinding the carrier film in a state where another surface thereof folded to inside at a tip-end configuring a head portion of a peeling member and the carrier film is passed around the peeling member, and backwardly feeding a leading end of the optical film sheet supported on the carrier film to a predetermined feeding position provided at upstream of the tip-end of the peeling member; a second step of operating a film leading end detecting means when the leading end of the optical film sheet is unwound together with the carrier film and stopped at the predetermined feeding position, to read the leading end of the optical film sheet; a third step of forwardly feeding the leading end of the optical film sheet to the predetermined laminating position, while peeling the optical film sheet together with the adhesive layer from the carrier film by winding the carrier film; a fourth step of forwardly feeding the panel component to be laminated to the optical film sheet from a predetermined waiting position to the predetermined laminating position; and a fifth step of laminating the optical film sheet and the panel component via the adhesive layer while further peeling the optical film sheet together with the adhesive layer from the carrier film, when the panel component and the leading end of the optical film sheet arrive at the predetermined laminating position.
