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 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.

L'invention concerne un dispositif assurant le nettoyage, l'apprêt et la préparation d'une surface sur laquelle on souhaite appliquer un joint statique, un adhésif ou autre agent de liaison. Le dispositif comprend un robot (18) capable de se déplacer le long d'axes multiples, qui supporte un effecteur terminal et permet à celui-ci de se déplacer le long de la surface (25) à nettoyer. Un ensemble fournisseur de feutre (12) fournit du feutre (14) sous tension à l'effecteur terminal (20). Un système de distribution de fluide de nettoyage (34, 34a, 36a) applique le fluide en question via l'effecteur terminal, directement sur le feutre, aux fins d'application sur la surface à nettoyer. Par ailleurs, l'effecteur terminal comprend un élément d'essuyage en élastomère du type raclette en caoutchouc (51) qui racle la surface afin d'éliminer les contaminants bruts de la surface. Une lame d'air (52) sèche à force les résidus de fluide. Le mouvement de l'effecteur terminal est contrôlé par un organe de commande numérique préprogrammé (22) qui, par ailleurs, assure une application précise du fluide sur le feutre, régit l'avancée du feutre à la volée, et contrôle la pression que l'effecteur terminal exerce sur la surface à nettoyer.
