The Challenge

Electrode slurry is coated onto copper and aluminium foil to facilitate electric flow. The metal surface, separator, and coating must be inspected for potential surface or edge defects as well as uniform shape and thickness.

The Solution

Gocator smart 3D laser profilers are used during various stages of EV battery manufacturing in order to ensure component and assembly tolerances are met, and that maximum cycle life and safety are achieved.

Gocator provides high-speed profiling of the edges of coated electrode sheets to ensure the correct dimensional tolerances are met.

Surface Defect Detection - Gocator scans, locates, and executes pass/ fail decisions on surface defects such as dents, scratches, and stains. The sensor also provides powerful defect detection on the battery seal, identifying grooves, tilting, and height variation.

Gocator scans and identifies defects in the weld seam such as breakages, overflow, offset, cracks, air holes, excessive roughness, discoloration, and more.

 

Operational Impact
  • [Process Optimization - Real Time Monitoring]

    Gocator can be used to scan cell sheets and ensure they are correctly aligned for stacking.

    Gocator has a built-in position detection tool that leverages data from all four sides of the battery to extrapolate the correct weld position.

     

  • [Data Management - Data Collection]

    High-Performance Scanning of Specular Surfaces - Gocator is able to generate precision 3D data even on highly specular surfaces like metal weld seams.
