ABSTRACT:
Method and apparatus for transporting a lead frame which can be shared for directly-stacked lead frames and for frames--which are stacked while inter leaves are sandwiched, respectively, between them--and which allows two lead frames sticking to each other to be efficiently recovered without deactivating the lead frame transport apparatus. An apparatus for transporting a lead frame to a transport path from a stack of lead frames stored in a magazine through use of a transport head are provided with a recovery head, two-sheet pick-up sensors, and a recovery section for recovering an inter leaf which doubles as a recovery section for recovering two lead frames sticking to each other. In a case where the lead frames are stacked while the inter leaves are sandwiched, respectively, between them, the recovery head transports the inter leaf to the recovery section, where the inter leaf is recovered. In contrast, in a case where the lead frames are directly stacked, if a transport head erroneously picks up two lead frames, the two-sheet pick-up sensors detect the picking up of two lead frames. The two lead frames are temporarily returned to the magazine and are transported by means of the recovery head to the recovery section, where they are recovered.
