  • Publication number: 20090194922
    Abstract: A configurable end-of-arm tool attachable to an articulable robotic arm is described. The end-of-arm tool comprises a rail element, a machine-adjustable swing arm, a machine-adjustable extendable shaft attached to the swing arm. A machine-adjustable rotator set is attached to the extendable shaft, and a workpiece interface tool is attached to the extendable shaft. The swing arm, the extendable shaft, and the rotator set are machine-adjustable to place the workpiece interface tool at a predetermined position.

  • Publication number: 20090193642
    Abstract: An end-of-arm tool having a workpiece interface tool is attachable to an articulable robotic arm. The end-of-arm tool can be configured by engaging an adjustable modular unit including a swing arm, a cylinder, and a workpiece interface tool to a rail element of the end-of-arm tool. The adjustable modular unit machine-slides in the rail element to a preferred x-axis position, machine-pivots to a preferred angular orientation, and machine-extends along a longitudinal axis of the cylinder to a preferred z-axis position, and machine-rotates to a preferred rotational angle about the z-axis.

  • Patent number: 7001130
    Abstract: Robotic rack loading apparatus and method include features and loading steps that provide essentially damage free rack loading of automotive panel assemblies into a specially designed rack. The rack includes dunnage elements containing sets of slots with lead-in upper edge angles and sensing holes associated with the slots. The robot carries a modified end of arm tool including a sensor to sense the location of a sensing hole to position a panel for loading into a corresponding set of slots. Another sensor preferably senses objects or structure in the rack to position the tool in a preload position. A compliant device allows lateral and longitudinal compliance of the end of arm tool to allow assemblies to be funneled into position in the slots without encountering damaging stress. A programmed robot can thus automatically load panel assemblies into the rack without damage.
