Wrinkle and dent detection on pouch cell surfaces
The pouch cell stops on its pallet under the gantry and is imaged from above under diffuse lights fired in turn from four directions. AI-based surface analysis extracts wrinkle and dent regions as a mask; a suspect cell is pushed into the reject bin.
The defect mask is sent to the operator display and the cell record; the PLC triggers the reject pusher and the suspect cell is removed to the reject bin together with its pallet.

Need
The flexible reflective pouch surface changes its reflection even with small folds. Normal package texture is difficult to distinguish from wrinkle and dent traces under a single light direction.
Solution approach
Diffuse bar lights around the overhead camera fire in turn; light from each direction shades a different slope of a fold. The AI model extracts regions that differ from normal package texture in these images as a mask; mask position and area are evaluated for the decision.
Process steps
- 01
Positioning
The pouch cell arrives on its pallet and stops under the gantry.
- 02
Acquire
The diffuse lights fire in turn from four directions; the overhead camera captures an image for each.
- 03
Analyse
AI analysis masks the suspect fold and extracts its area.
- 04
Decide
The wrinkled cell is pushed into the reject bin.
