Claims

[Claims for Utility Model Registration] 1. In a lead frame supply device that picks up a large number of stacked lead frames stored one by one at a pick-up position and supplies them onto a conveyance means such as a rail, above the pick-up position. a pick-up device that is arranged and moves up and down in the direction of the stacked lead frames and picks up the topmost lead frame; and a pick-up device that is arranged between the conveyance device and the pick-up device and picks up the lead frame. at least 2 for
It has a book placement arm and can move up and down between a position where the bottom surface of the lead frame placed on the placement arm matches the top surface of the transport means and a position where the bottom surface of the lead frame is higher than the top surface of the transport means. a transfer means capable of entering between the placement arms of the transfer means and horizontally movable between a position directly below the pick-up means and a position entering between the placement arms of the transfer means; , when receiving the lead frame picked up by the picking up means directly below the picking up means and moving in the direction of the delivery means, the preceding lead frame whose end face is placed on the delivery means is conveyed. a moving body that pushes out the lead frame onto the means, carries the trailing lead frame to the delivery means, and transfers the lead frame onto the placement arm by moving the placement arm of the delivery means up and down. A lead frame supply device characterized by: 2. A lead frame supply device that picks up a large number of stacked lead frames stored one by one at a pick-up position and supplies them onto a conveyance means such as a rail, which is arranged above the pick-up position and collects the stacked leads. a pick-up device that moves up and down in the direction of the frame and picks up the uppermost lead frame; and at least two pick-up devices that are disposed between the conveyance device and the pick-up device and that place the lead frame on the top layer.
A delivery means having a book placement arm and provided so that the bottom surface of the lead frame placed on the placement arm is aligned with the top surface of the conveyance means, and the delivery device capable of entering between the placement arm of the delivery means. The lead frame is movable horizontally between a position directly below the pick-up means and a position where it enters between the placement arms of the transfer means, and the lower surface of the lead frame received from the pick-up means is directly below the pick-up means. is movable up and down between a position where the lead frame coincides with the upper surface of the mounting arm and a position where the lower surface of the lead frame is lower than the upper surface of the mounting arm, When the picked up lead frame is received and moved in the direction of the delivery means, the leading lead frame placed on the delivery means at the end face is pushed out onto the conveying means, and the trailing lead frame is pushed out onto the conveying means. A lead frame supply device comprising: a moving body that transports the lead frame to a delivery means and moves the lead frame up and down to transfer the lead frame onto a mounting arm. 3. The lead frame has a plurality of package parts in which semiconductor elements and the like are sealed with resin, which are formed at predetermined intervals, and the delivery means is brought into contact with a side wall surface of the package part brought in by a moving body, 3. The lead frame supplying apparatus according to claim 1, wherein the lead frame is regulated to adjust the position of the lead frame with respect to a loading position onto the conveying means.
