Flatness Detection with SinceVision Laser Displacement Sensors
In lithium battery production, maintaining strict dimensional accuracy of the external top cover and aluminum shell is essential. Any deviation in the flatness of the top cover can disrupt the subsequent welding and liquid injection processes. SinceVision's SD33-85 Laser Displacement Sensors can be strategically placed to measure the top cover's points, accurately determining flatness by analyzing the ranging values from each sensor. This ensures optimal precision in the production process, crucial for maintaining high-quality standards in the lithium industry.
