Sealing Nail Welding Guide in Lithium Battery Production Using SinceVision's Laser Displacement Sensor
In the lithium battery production process, after the electrolyte is injected into the battery shell, it is crucial to ensure precise sealing at the welding station to achieve complete isolation between the internal battery components and the external environment. The optimal sealing nail welding rate is essential for quality control. SinceVision's SD33-85 Laser Displacement Sensor is used to accurately measure the welding height of the sealing nail and verify its position, guiding the welding equipment mechanism to ensure proper sealing in the production process.
