Stacking Machine Inspection: Separator Deviation, Electrode Damage, and Positioning Detection
Industry pain points and demands
In the advanced lithium battery production industry, particularly for stacked batteries, manufacturers face several critical challenges:
Separator Deviation: Misalignment of separators can lead to reduced battery efficiency and potential safety issues.
Electrode Damage Detection: Undetected damage to electrode edges can compromise battery performance and longevity.
Precise Electrode Positioning: Inaccurate positioning of electrodes can result in suboptimal battery construction and reduced capacity.
These challenges, if not addressed, can significantly impact production efficiency, yield, and overall product quality in the highly competitive lithium battery market.
