Surface Inspection of a PHEV Battery Cell Using 2D/3D Profile Sensors in Automotive Construction

In electric car assembly lines, PHEV battery surfaces must be checked for foreign bodies such as screws with micrometer accuracy. These foreign bodies can lead to serious damage and thus to a high risk of fire. For optical surface inspection, four 2D/3D profile sensors are guided over the battery via a linear unit to measure the area. The height profiles are then combined into a 3D point cloud, which is analyzed using software. Thanks to laser class 2M, precise results are achieved and reflections are suppressed.

MLWL 2D/3D Profile Sensors

2D/3D profile sensors from the weCat3D series use the principle of laser triangulation to create 2D height profiles and 3D point clouds. The MLWL model offers unbeatable profile quality thanks to its optimized, high-quality optics.
