Battery Sheet Thickness Measurement with Laser Displacement Sensor
In the photovoltaic industry, large battery sheets are segmented into smaller sheets using laser cutting technology. Before the cutting process begins, the thickness of the battery sheets must be measured to ensure the laser power matches the required specifications. Proper adjustments prevent damage to the material and ensure optimal cutting performance.
SinceVision's SG5025 Laser Displacement Sensors enable precise and non-contact thickness measurement. Utilizing a through-beam configuration with two sensors, the system collects continuous thickness data, achieving repeatability of 0.005 mm and a maximum sampling frequency of 590 kHz. This real-time feedback ensures reliable, high-quality cutting.
