Abstract
Inspection of cell-to-tab welds in module assembly for battery pack is one the most critical processes in the production of battery packs for transportation electrification. A procedure suitable for the segmentation of weld images on module assembly lines is proposed to separate them into weld and tab regions. The procedure is centred around identifying the edge of the weld and the convex hull region that includes it. The edge is detected with a fuzzy logic rule-based inference system. The procedure is demonstrated with a set of 71 images that are labelled to establish a comparison reference, the so called ground truth. Particle swarm optimisation is used to find values of the parameter procedure that result in a a local minimum of the mean percent error (MPE). An MPE of 4.25 per cent has been obtained.
