Abstract:

A stacked robotic work cell process station is provided which includes first and second module chambers (14) and (26) which have associated therewith work surfaces (10) and (22). The first module chamber (14) is disposed above the work surface (22) in the second chamber (26) and staggered with respect thereto. A conduit (34) is provided for interfacing the upper surface of the chamber (26) with a point parallel to the upper surface of the first chamber (14) and adjacent thereto. A lower conduit (16) interfaces the lower portion of the first cell chamber with the lower portion of the second module chamber (26). A baffle (20) is provided for adjusting the air flow between the two chambers to provide isokinetic air flow at the upper surface of the stacked configuration.
