Electrode slurry is coated onto copper and aluminum 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.
Cell Pre-Assembly Inspection
Gocator® delivers high-performance 3D surface inspection of the coating on electrode sheets––detecting imperfections such as bubbles, holes, and splits.
Electrode Coating Inspection
Gocator® provides high-speed profiling of the edges of coated electrode sheets to ensure the correct dimensional tolerances are met.

Gocator® provides accurate width gauging of the dimensions of the separator and electrode.
Electrode Width Gauging
Gocator® scans and measures the distance between tabs on a cell sheet to meet dimensional tolerances.
Tab Distance Gauging
A separator and electrode are joined together, and the joined cell (including anode and cathode) is either wound, rolled, or stacked. Stacked cells are then housed in a metal casing and sealed by welding.
Cell Assembly Inspection
Gocator® can be used to scan cell sheets and ensure they are correctly aligned for stacking.
Stacking Alignment Inspection
Gocator® has a built-in position detection tool that leverages data from all four sides of the battery to extrapolate the correct weld position.

Ultra high-speed and compact 3D laser profile sensors for robust inline inspection
The built-in Surface Barcode tool reads image-based and laser-etched DataMatrix codes on the copper siding of stacked electrodes.
Barcode Reading
Prior to welding, a Gocator® multi-sensor network delivers high-speed 3D laser profiling and a built-in tool to measure the gap & flush between the battery cell and its metal casing.
Gap & Flush Measurement
Connect Gocator sensors to GoMax Smart Vision Accelerator or a PC in order to read, recognize, and validate flat (2D) or raised (3D) alphanumeric characters. GoMax comes with an onboard OCR engine and pre-trained deep learning datasets.
Optical Character Recognition
Battery cells are inspected for surface quality, flatness and potential defects such as outliers, cracks, edge breaks, and more.
Battery Surface Inspection (Flat Cell)
Only 3D gives you the shape data required to inspect battery surface features and dimensions for defects such as bulges, fissures, warps, and more.
The 3D Advantage
The built-in barcode tool locates and reads QR codes on the battery surface for accurate tracing and tracking. An OCR tool is also available to decode alphanumeric content.

Multiple cells are stacked together to form modules. Modules are combined to form battery packs. Both at the module and pack level, components have to be inspected for correct assembly and final weld quality.
Module and Pack Assembly Inspection
Gocator® scans and identifies defects in the weld seam such as breakages, overflow, offset, cracks, air holes, excessive roughness, discoloration, and more.
Weld Seam Defect Detection
Weld Seam Height/Position Inspection
Gocator® scans weld seams for correct height using a native height detection tool based on blob analysis.

Gocator® generates precision 3D data even on highly specular surfaces like metal weld seams.
High-Performance on Specular Surfaces
In electric vehicles, a large tray/pan sits under the floor panel. The lithium-ion battery module is glued to this tray. The glue bead application in this assembly has to be inspected for correct dimensions and surface quality.
Battery Final Installation Inspection
A robot-mounted Gocator® laser line profiler scans the glue bead application and generates a 3D surface, to which you can apply built-in measurement tools and control logic.
Smart 3D Robot Vision Guidance
Built-In Surface Track Tool
This built-in measurement tool allows you to perform width, height, offset, and continuity inspection at defined points along the glue bead path and return global measurements and statistics.
