Abstract
A shuttle-actuated singulation apparatus (10) for use in handling integrated circuit devices (16). A shuttle (39), acting to isolate or singulate an individual integrated circuit device (16) for transfer to a test apparatus, is included. A shuttle assembly (30) is carried by a splined shaft (34) for rotational movement of shuttle (39) carried thereby. The assembly (30), additionally, is moved laterally by means of a drive cable (36). Rotation of a shuttle barrel (32) and associated upward pivoting of shuttle projectiles (42) carried by barrel (32) effects engagement of a bell crank (70) which, in turn, engages a belt drive mount (82) carrying a drive belt (80). The drive belt (80), thereafter, is engaged with an integrated circuit device (16) to impel the device (16) out of a track (12) in which it is received. The engagement of the shuttle projectiles (42) with a shoulder (72) of the bell crank (70) pivots the belt drive mount (82), thereby overcoming belt drive mount biasing spring (90) which normally retains the belt drive mount (82) in its original position. A stop (60) associate with each track (12) is also engaged by upward rotation of the shuttle projectiles (42). Engagement…
