1461593 Electrical interconnections in batteries LUCAS BATTERIES Ltd 4 April 1974 [26 April 1973] 19823/73 Heading H1B [Also in Division B3] In making electrical interconnections between battery plates 13 in adjacent cells of a storage battery box 11 having partition walls 12 with conductive lugs 14a, 15a extending from battery plates in adjacent cells to adjacent holes in partition walls, a conductive connector 17 or connectors extends between the lugs of two adjacent cells, a pair of resistance welding electrodes 34, 35 are located adjacent the lugs and current is passed between them to weld the lugs and connector or connectors together, the box is moved relatively to the electrodes in a first direction and then in a second direction at right angles to the first direction to position a further pair of lugs adjacent the electrodes, these lugs and their connector or connectors are welded together and the steps are repeated until all the required interconnections are produced. A lead slug 17, in an embodiment, having a tapered end is passed through a hole in each lug and in the partition wall, the ends of the slug projecting slightly from the end surfaces of the lugs. When slugs are in position in each connection point, the connection points being alternately adjacent opposite side walls, the box is positioned on a roller conveyer 23, Fig. 6, at a feeding station. The box is then fed along the conveyer to move along a guideway 42 provided by two members 43, 44 until it reaches a work stop. A platform 31 is then automatically raised by a ram 32 to project ribs on the platform between the rollers 23 to engage and lift the box towards the resistance welding tool 18 where the first connection is welded. The platform is then automatically retracted and the guideway 42 is moved laterally by a ram 40, the work stop is retracted and the box is advanced by the rollers to bring the next connection, adjacent the other side wall, beneath the electrodes. The box is again raised and the next connection is welded. All the connections are similarly made with further boxes being fed from the feeding station. Instead of a separate slug for each connection each lug 14 and/or each lug 15 may have an integral projection. |
