ABSTRACT:
An apparatus for automatically connecting battery plate units of adjacent cells through apertures in partitions between adjacent cell chambers of battery cases with said connection being effected by pressing lead projections of adjacent battery plate units together within each partition aperture and electrically fusing said projections together to form an electrical connection therebetween and completely fill said aperture and seal said chambers: comprising a work station in said apparatus where said plate units are connected, a conveyor for moving battery cases assembled with plate units into and from said work station, an electrode assembly comprising a pair of opposed electrodes adapted to fit into adjacent cell chambers and over said projections and apertures, indexing means for effecting relative movement of the battery case and electrode assembly at said work station for bringing the battery case into exact registry with the electrode assembly for effecting the connection, means for forcing said electrode assembly relatively toward each other against the projection and squeezingly pushing the projections into electrical contact within said aperture, means for supplying an electric current to said electrodes for effecting fusion of said lead projections within said aperture to form an internal connection between the adjacent lead projections and provide a complete sealing of the aperture between adjacent chambers, means for effecting relative movement between said electrode assembly and said battery case to additional positions whereby all of the connectors will be connected to all of the partitions containing apertures and provide a completed connection of said plate units in the overall battery.
