A plurality of spring clips (30), each having an elongated central member 2) with first (40) and second (38) ends and a plurality of resilient arms (36) radially extending therefrom, are simultaneously transferred between a transfer plate (90) and a pallet (20). The first ends (40) of the member (32) are lockably engaged in the transfer plate (90) with the second ends (38) thereof positioned into apertures (24) in the pallet (20). The central member (32) is rotated to release the first ends (40) from the transfer plate (90) while simultaneously lockably engaging the second ends (38) to the pallet (20) to secure the clips (30) therein and to capture a chip carrier (10) between the ends of each arm (36) and the pallet (20).

Methods for transferring spring clips

A plurality of spring clips (30), each having an elongated central member (32) with first (40) and second (38) ends and a plurality of resilient arms (36) radially extending therefrom, are simultaneously transferred between a transfer plate (90) and a pallet (20). The first ends (40) of the member (32) are lockably engaged in the transfer plate (90) with the second ends (38) thereof positioned into apertures (24) in the pallet (20). The central member (32) is rotated to release the first ends (40) from the transfer plate (90) while simultaneously lockably engaging the second ends (38) to the pallet (20) to secure the clips (30) therein and to capture a chip carrier (10) between the ends of each arm (36) and the pallet (20).

Spring clip transfer apparatus

Method and apparatus for automated spring clip insertion and removal

A spring clip (30) for holding chip carriers in place on a pallet (20) serves to urge a case (12) seated in each of a plurality of pallet cavities (22) against an underlying lid (14) therein during fabrication of the chip carrier (10). The spring clip (30) comprises a central shaft (32) which extends vertically through the center of a metal plate (31). The plate (31) has a plurality of radially outstretched resilient arms (36), each sloping downwardly from a separate side thereof and having an upturned end (37). The lower end (38) of the shaft (32) is sized for lockable engagement with a corresponding one of a plurality of receiving passages (24) in the pallet (20). Each passage (24) is surrounded by a group of pallet cavities (22). When the first end of each shaft (32) of the spring clip (30) is lockably engaged with the pallet (20), the chip carriers (10) are held on the pallet (20) by the ends (37) of the arms (36).
