POLARIZER ATTACHMENT DEVICE AND POLARIZER ATTACHMENT METHOD

WIPO Patent Application WO/2018/216096

A1

A polarizer attachment device 1 comprises: a supply unit 10 for pulling a strip-like raw polarizer 2 from a feed roll 5 to supply the same to a panel; a peeling unit 11 for peeling a separator film 2c; a transfer unit 13 for transferring a liquid crystal panel 4; an attachment unit 14 for attaching the raw polarizer 2 to the liquid crystal panel 4; an attachment detection unit 15 for detecting the attachment state of the raw polarizer 2; a raw-polarizer cutting unit 17 for cutting the raw polarizer 2; and a control device 30. The control device 30 includes: a cutting determination unit 31 that determines it is possible to cut the raw polarizer 2 when the attachment detection unit 15 detects that it is after the completion of the attachment of the raw polarizer 2 to the liquid crystal panel 4 and after the start of the attachment of the raw polarizer 2 to another liquid crystal panel 4; and a first cutting control unit 32 that controls the raw-polarizer cutting unit 17 to allow the same to cut the raw polarizer 2 between the liquid crystal panels 4 when the cutting determination unit 31 determines that it is possible to cut the raw polarizer 2.
