Battery manufacturers need measuring equipment for weld bead inspection for contacts. If weld beads are not constructed uniformly and symmetric then it results in increased current density over battery contacts and eventually overheating and severe harms to the system. To prevent this, donut shaped “Welding Beads” of battery contacts have to be checked with respect to several parameters: volume, center, radius, width, height parameters as well as the absence of defects in circular regions have to be verified. A Quelltech Laser Line Scanner is guided via a linear x-y axis over the weld beads acquiring a 3 D point cloud of these objects. A measurement software will compare these 3 D images against a tolerance channel and will determine pass or fail status. Failed parts are sorted out automatically. More Details »
