For realizing above-mentioned clamping and tension adjustment, the straight line transfer mechanism (not shown) that is used to clamp the clip (not shown) of polarization film 2 or this clip straight line is moved is arranged on carrier 3, after the clamp polarization film 2, by the straight line transfer mechanism this clip straight line is moved, polarization film 2 is remained on the carrier 3 keeping under the state of flatness thereby can apply tension force operation.
If carrier 3 is transplanted on line scanning handover device 31g and is transplanted on inspection portion 30 by loading shuttle 20, implementation step S30 then: to remain on polarization film 2 on the carrier 3 carry out successively the transmission inspection and on/the line scanning inspection and the field scan inspection of lower surface, then carrier 3 is transplanted on unloading shuttle 40.
For carrier 3 being transplanted on unloading shuttle 40, at first, if maintaining the carrier 3 of polarization film 2 is transplanted on line scanning and transfers device 31g, then implementation step S31: the first air pressure connector 4 that is set in place on the body 1 of line-scan camera 31 positions of inspection portion 30 is combined with the second air pressure connector 3a of carrier 3.At this, combine in order to make the second air pressure connector 3a that is provided with on the first air pressure connector 4 that is arranged on line-scan camera 31 1 sides and the carrier 3, after its first first air pressure connector 4 that combines is removed, combination again.
If the first and second air pressure connectors 4,3a combination and carrier 3 are transferred device 31g by line scanning and are transferred, then implementation step S32: the polarization film 2 that remains on the carrier 3 is carried out the transmission inspection.In this step S32, the pollution source of the big foreign matter, bubble or the scratch that comprise in the polarization film 2 are taken.
If transmission inspection end and the polarization film 2 that remains on the carrier 3 are transferred continuously by line scanning handover device 31g, then implementation step S33: the lower surface by 31 pairs of polarization films 2 of line-scan camera carries out the line scanning inspection; And implementation step S34: the inspection of the lower surface of polarization film 2 finishes, and carries out the line scanning inspection by 31 pairs of upper faces by the polarization film 2 of line scanning handover device 31g handover of line-scan camera.Whether the conversion mutually of the enforcement of step S33, S34 order takes existing as the flaw of micro-foreign matter that comprises or bubble etc. in polarization film 2.
If on the line scanning polarization film 2/inspection of lower surface finishes, promptly on the polarization film 2/the line scanning inspection of lower surface finishes, implementation step S35 then: the carrier 3 that will maintain polarization film 2 is transplanted on field scan and transfers device 32e.The result who implements, transfer device 32e, then implementation step S36 if carrier 3 is transplanted on field scan: the polarization film 2 that remains on the carrier 3 by 32 pairs in field scan video camera carries out field scan and checks light leak.
If the light leak inspection of polarization film 2 finishes, then implementation step S37: the operation of ruling on polarization film 2.If in step S37, on polarization film 2, drawn line, implementation step S38 then: transfer device 32e by field scan carrier 3 is transplanted on unloading shuttle 40, can omit under the situation of step S37 necessity of line and carry out.
Be transplanted on unloading shuttle 40, then implementation step S40 if maintain the carrier 3 of the polarization film 2 that check to finish: carrier 3 is transplanted on outgoing position and outputs to unloading portion 50 according to the check result of polarization film 2.
