PROCESS AND APPARATUS FOR MULTIPLE SURFACE TREATMENTS OF BATTERY CANS

摘要

Apparatus for surface treatment of battery cans, including cleaning and electroplating of the interior and exterior surfaces of battery cans as they are transported along a continuously moving production line. The battery cans are automatically loaded from a conveyor onto workpiece holders on a series of circular carriers. Surface processing enclosures operated by cam followers are arranged to enclose the battery cans so that a processing fluid may be automatically injected. The processing fluid may simply be a surface cleansing or drying agent or in the case of electroplating, the processing fluid is a liquid electrolyte so that a plating voltage can be applied to plate either the external or internal surfaces of the battery cans.
