Abstract: A robotic transport and assembly system includes a worktable upon which are supported a printed circuit board conveyor, a controllably displaceable circuit component feed mechanism and a robotic manipulator, mounted on the worktable and having a multi(four)-axis end effector, for controllably seizing an electronic circuit component from the component feed mechanism and placing the seized component on the printed circuit board for surface mounted attachment. The controllably displaceable circuit component feed mechanism, which includes a component feed device and an associated feeder device positioning table, is mounted on the worktable at a position adjacent to the position whereat a printed circuit board is supported for the pick and placement operation of the robotic manipulator. The component feed device controllably supplies a plurality of the components to be seized by the end effector and placed on said workpiece by the robotic manipulator.

Abstract: A feed apparatus employs a vision controlled robotic manipulator in which components are dispersed into a single layer with a random orientation. The dispersing mechanism comprises a vibratory feed plate having an input hopper which receives components to be dispersed. The feed plate is controllably vibrated such that components are urged along its top surface. Located in the travel path of the components above the feed plate is a rotating cylindrical brush, which sweeps components as they are being vibrated by the feed plate and causes a single layer of components to emerge from beneath the brush and pass to a viewing/pick-up zone. This zone is backlighted, so that the components may be observed by a camera mounted directly above the backlighted layer. The camera image is analyzed by a video data processor to determine the location and orientation of a component. This information is applied to a manipulator control program for driving a robotic manipulator to pick-up a component for transport to a workpiece.
