Problems solved by technology

Electroplating a moving work piece is particularly difficult.
The foregoing patents do not address the problem of loading and unloading the workpiece in a continuous plating process.
While the apparatus is suitable for plating the exterior of the article, it requires a semi-batch type loading of the work piece and does not provide for high speed plating with close clearances between the work piece and the anode.
However, there is no provision for plating the interior and the exterior surfaces of the battery cans.

Embodiment Construction

[0020] Referring now to FIG. 1 of the drawing, a cleaning and plating system is shown. Surface treatment units are indicated at 10, 12, 14, 16 arranged in a line and receiving work pieces, in this case battery cans, traveling along a conveyor at 18 and departing the system on a conveyor at 20. Intermediate conveyors 22, 24, 26 move the battery cans from one unit to the next. A loading dial 28 and an unloading dial 30 serve as interfaces to transfer battery cans from conveyor 18 to the surface treatment unit 10 which is rotating in a direction indicated by the arrow, and to remove treated battery cans and transfer them to the intermediate carrier 22 for transport to the next surface treatment unit 12. Surface treatment unit 10 is adapted for degreasing and activating the battery cans through treatment with surface cleansing agents contained in tanks indicated at 32, 34. An example of such cleansing agents is AQUAEAS from Hubbard Hall. A water treatment system 36 is shown for the purp...

Abstract

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.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates generally to process and apparatus for surface treatment of work pieces as they move along a production line, and more particularly to surface treatments 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. [0002] Battery cans are produced today in huge quantities for use in the manufacture of electrolytic cells, such as AA, AAA, C and D cylindrical batteries and also prismatic batteries for special applications. The battery cans are usually manufactured by transfer presses, which draw the battery cans from an initial metal stamping into hollow longitudinal casings open on one end with a substantially uniform cross section along the length of the casing. Intermediate manufacturing steps after drawing the battery cans usually requires degreasing the interior and exterior surfaces, washing, cleaning and d...
