Cell Terminal Addressing and Height Measurement with Laser Displacement Sensor
Industry pain points and demands
In lithium battery production, accurate identification of cell terminal position and height is crucial to ensure reliable connections and assembly precision.
SinceVision’s SG Series laser displacement sensors are engineered to meet these needs with exceptional precision and speed. Offering 0.05μm repeatability and dynamic measurement at 88kHz, the system captures terminal coordinates and height deviations in real time.
With focus error controlled to ≤0.05mm, the sensor provides robust guidance for polarity recognition and alignment, enhancing the accuracy and consistency of automated processes in cell-pack assembly lines.
