ABSTRACT:
The present invention is a device for receiving an integrated circuit (10) presented at a pick-up station (22), transferring the integrated circuit (10) laterally to a spaced output chute (84, 90), and depositing the integrated circuit (10) into said chute (84, 90). The device includes a shuttle (24) mounted for pivotal and lateral movement on a shaft (40). The shuttle (24) is driven by an angled arm (62) mounted pivotally beneath the shuttle (24). The arm (62) is pivoted about an axis by means of a motor (56) and a linking shaft (52). A housing (76) carried by the arm (62) at an end thereof opposite the end by which it is pivoted encases and holds therein a spherical bearing (78) which is free to swivel within the housing (76) for rotation about three mutually perpendicular axes. The bearing (78) has an aperture (80) formed therethrough. The aperture (80) accommodates a rod (72) carried by the shuttle (24) at its underside. The rod (72) extends generally parallel to an axis along which integrated circuit devices (10) enter the shuttle (24). As the drive arm (62) is pivoted one way or another, it draws the shuttle (24) both laterally and pivotally about the shaft (40) on which the shuttle (24) is mounted.
