Separator Deviation Measurement and Width Detection
Industry pain points and demands
In the battery cell production industry, precise control during the winding process is crucial for product quality and performance. Manufacturers face several challenges:
Real-time Edge Position Detection: The need to continuously monitor the alignment of upper and lower separator edges during winding.
Material Variability: Adapting to different light transmittance properties of dry and wet separators while maintaining correction accuracy.
Width Measurement: Accurately measuring separator width to ensure consistency and quality control.
These challenges, if not addressed, can lead to misalignment issues, inconsistent product quality, and increased waste in battery cell production.
SinceVision Solutions: SE2 Series Through-Beam Edge Sensor
01Versatile Material Compatibility: The SE2 Series adapts seamlessly to both dry and wet separators, ensuring consistent correction accuracy regardless of material light transmittance differences.
02High-Precision Edge Detection: By installing SE2 sensors in opposite pairs at the winding station, manufacturers can achieve real-time, through-beam measurement for precise edge alignment monitoring.
03Accurate Width Measurement: Utilizing a calibratable bracket system, two pairs of SE2 sensors can be installed on both sides to provide precise separator width measurements, meeting customer requirements for comprehensive quality control.
