Cell Hot Pressure Monitoring in Lithium Battery Production Using SinceVision's Laser Displacement Sensor
In lithium battery production, cell hot pressing shaping plays a critical role in ensuring structural integrity. During the process, parameters like pressure, pressure time, and template temperature must remain stable to prevent issues like powder loss or fractures when the cell bends. The SinceVision SD33-50 Laser Displacement Sensor is used to continuously monitor the stroke and bottom dead center of the hot press, providing real-time feedback to the upper computer. This ensures accurate pressure drop measurement and optimal process control, making it an essential tool for maintaining quality in automobile and lithium industries.
