Abstract

This article relates generally to automated assembly lines and more particularly to a robot hand having fingers specifically adapted for picking up flat gears used in the assembly of inked ribbon cartridges. The ribbon cartridge during assembly utilizes a drive gear set which incorporates a flat gear with a .250" hole through the center. The pickup device of this article is utilized to both pick up the gear and sense whether or not the gear is present. Pickup 1 consists of a body 2 which is mounted fixedly to the turret of a robot arm (not shown) by a boss 3. Body 2 is milled out to accept a fixed finger 4 which is held in place by a screw 5. A moveable finger 6 is held in place by a screw 5. A moveable finger 6 is similarly held in a moveable holder 7.
