Abstract
This invention relates to an apparatus that provides, in combination, a multi-spray counterflow rinse system that is interconnected to a plating barrel which includes an internal spray nozzle so as to spray rinse a multiplicity of chemically treated workpieces which are supported within the plating barrel. The plating barrel is rotatably carried by a superstructure from one process station to another so as to be positioned within a single in-line rinse tank that is employed during the steps of an electroplating process. The invention includes two embodiments of a self-aligning coupling device defined by first and second coupling members that are interposed in a rinse-solution supply line. One coupling member is secured to the superstructure and the other coupling member is mounted to the rinse tank, whereby the two coupling members are coupled together as the superstructure and barrel are lowered into the rinse tank for the rinsing process.
