Case Study | CIS Inspection for Battery Electrode Slitting
Seven CIS cameras combine timed strobe lighting and low-distortion, close-range imaging to inspect battery electrodes in a compact slitter. One station handles web alignment, width measurement, and defect detection across film, groove, and ceramic-coated areas.
One station, three tasks
A battery manufacturer needed web alignment, width measurement, and defect inspection inside a fast, space-constrained electrode slitter. Its previous CCD system no longer met the required accuracy and flexibility across product sizes.
Three requirements at the slitter
The manufacturer wanted to catch surface defects before the next process, correct lateral drift as the web is slit, and measure strip width across different product sizes without slowing production. The existing CCD setup struggled to combine these tasks in the available machine space.
From imaging to control
With synchronized strobes, one CIS station can image different features at different illumination phases. Edge position drives web correction, while the same distortion-free images support width measurement and inspection of film, grooves, and ceramic-coated areas. The small integrated head is easier to commission and service than a separate camera, lens, and lighting assembly.
Seven compact CIS camera sets
INSNEX and the customer's vision team selected seven CIS camera sets. Timed strobe lighting and bright diffuse line lights let a single station capture the features needed for alignment, measurement, and defect detection.
Short-range, distortion-free 1:1 imaging gives consistent dimensions across the field. The compact cameras simplify installation and setup without extensive machine changes.
Production benefit
The system shows defects in film, grooves, and ceramic-coated regions while supporting accurate web correction and width measurement. The customer highlighted the small footprint and straightforward commissioning.
