Electrode Plate and Separator Deviation Detection: Advanced Solutions with SE2 Series Sensors
Industry pain points and demands
In the battery cell production industry, particularly during the winding process, manufacturers face several critical challenges:
Signal Interference: Traditional analog communication systems are prone to signal interference, potentially leading to inaccurate measurements and quality issues.
Complex Wiring: The extensive wiring required for one-to-one sensor-to-controller configurations increases installation time and maintenance complexity.
High Costs: The need for additional AD conversion modules and individual controllers for each sensor significantly increases overall system costs.
Precision Requirements: Accurate detection of deviations in positive and negative electrode plates and separators is crucial for maintaining product quality and consistency.
These challenges can result in reduced production efficiency, increased costs, and potential quality control issues in battery cell manufacturing.
SinceVision Solutions: SE2 Series Through-Beam Edge Sensor
01Advanced Communication Protocol: The SE2 Series utilizes EtherCAT bus communication, ensuring stable and interference-free signal transmission. This eliminates the need for AD conversion modules and significantly improves measurement reliability.
02Wide Range Sensing: With a sensing head range of 24mm, the SE2 Series provides comprehensive coverage for electrode plate and separator deviation detection, enhancing overall process control.
03Streamlined Configuration: The system adopts a 1-to-4 configuration, allowing one EtherCAT communication module to connect up to 4 sensor heads. This design dramatically reduces wiring complexity and installation time.
