TRANSFER APPARATUS FOR LEAD FRAME

摘要

A lead frame transfer device having a pair of guides (4, 5, 6) and a transfer mechanism (43). At least one of the guides has a first guide rail (4) adapted for moving in the widthwise direction of a lead frame, a second guide rail (6) which is biased by a biasing mechanism (7) to cause the second guide rail toward the first guide rail to the widthwise direction of the lead frame so that the position of the second guide rail with respect to the first guide rail can be varied. Depending upon the widthwise size of a lead frame, the first guide rail of the guide is moved in the widthwise direction of the lead frame by a driving unit. In response to the movement of the first guide rail, the second guide rail is moved concurrently under the force of a biasing mechanism (7) and the lead frame can be hold at a predetermined position under the pressure of the biasing mechanism.
