Abstract
An apparatus cleans, primes and prepares a surface onto which a gasket, adhesive or other bonding agent is to be applied. The apparatus includes a robotic device capable of movement along multiple axes. An end effector is supported by the robotic device (18) for movement along the surface (35) to be cleaned. A felt supply assembly (12) delivers felt (14) under tension to the end effector (20). A cleaning fluid delivery system (34, 34a, 36a) applies cleaning fluid through the end effector directly to the felt for application to the surface to be cleaned. The end effector also includes 42 a squeegee-like elastomer wiping device (51) which scrapes the surface by removing gross contaminants from the surface. An air knife (52) is provided which force-flashes fluid residue. The movement of the end effector is controlled by a preprogrammed numeric controller (22) which also provides for precise application of fluid to the felt, advancement of the felt on-the-fly, and monitoring pressure of the end effector against the surface to be cleaned.
