Quarantine-magazine sorting of battery cells by cosmetic findings
A cylindrical battery cell is imaged in a rotary nest and its circumferential surface is evaluated from line images. A cell with cosmetic findings is robotically transferred to a separate quarantine magazine rather than the assembly magazine.
Cosmetic grade, finding location and cell result are recorded. The robot lowers an NG cell into a separate quarantine magazine; electrical or thermal safety conclusions are not derived from this visual inspection.

Need
Reflections and scratch appearance vary with angle on a bright cylindrical housing. Cosmetic imaging is not an electrical safety test; findings must be limited to quarantine and review decisions.
Solution approach
An indexing table presents a cell to a side line-scan camera. Directional light and controlled cell rotation form a circumferential image. A surface model marks cosmetic findings by location; the PLC links the result to a transfer address and the robot selects the magazine.
Process steps
- 01
Infeed
The table indexes the cell into the scan nest.
- 02
Trigger and acquire
Line images are acquired under directional light.
- 03
Analyse
The cell rotates while circumference and findings are evaluated.
- 04
Class and position
The cell result is linked to the correct magazine address.
- 05
Controlled sorting
The robot lifts the cell into acceptance or quarantine.
