摘要:
Batteries having cell element assemblies electrically connected by a welded joint between adjacent cell element assemblies are manufactured in an automated machine including align, weld, test, and reject stations and a conveyor for transporting a battery case containing cell element assemblies to the stations with the transportation of the battery case being synchronized with operations at the various stations. A battery case, containing cell element assemblies, is transported to the align station wherein the cell element assemblies are aligned for welding. A test of the position of the cell element assemblies relative to each other and to the to the battery case and also of the electrical condition of the individual cell element assemblies is performed. The so aligned and tested battery cases are transported on the conveyor to the weld stations wherein the aligned conductive portions are pressed into engagement and welded. Upon completion of the welding, the battery case is transported, again on the conveyor, to the test station wherein the connections between adjacent cell element assemblies are tested both electrically and mechanically. The tested battery cases are then transported, on the conveyor, to the reject station where they are rejected if prior testing shows them to have been defective or allowed to pass out of the machine if acceptable.
摘要:
Apparatus for testing an intercell weld between adjacent battery cell element assemblies includes a plurality of pairs of test fingers engageable with battery cell element assemblies disposed on opposite sides of battery partition walls. When so engaged, the test fingers are operable to exert a load, both mechanical in tension and electrical, to determine the presence of defective welds. An automatic reject arrangement is associated with the testing mechanism. The reject arrangement is controlled by the testing mechanism and passes acceptably welded batteries while automatically moving those with defective welds to a reject conveyor line.

Apparatus for aligning conductive portions of adjacent cell element assemblies on opposite sides of battery partition walls so that an intercell weld can be made through those walls between the aligned conductive portions includes a plurality of pairs of bifurcated aligning extensions depending from an aligning head. A battery support is positioned below the aligning head and provision is made for producing relative movement between the aligning extensions and the battery support so that the extensions can be brought into engagement with conductive portions of cell element assemblies contained in a battery resting on the battery support. The pairs of extensions are relatively spaced in accordance with the relative spacing of the adjacent conductive portions of the battery cell element assemblies and the bifurcations in each pair of aligning extensions are relatively aligned so that the extensions will engage and align conductive portions of adjacent assemblies. Provision is also made for testing the position of the cell element assemblies in the battery as well as the position of the battery per se on the battery support. The testing arrangement is effective to produce a signal in the event of a completely misaligned battery or misaligned battery cell element assemblies.
