When manufacturing lithium-ion batteries, it is crucial that the electrode foils, anode, cathode and, if necessary, a separator foil, are always stacked alternately. The anode typically consists of graphite, while the cathode is made of lithium metal oxides. A gripper alternately picks up the cathode and anode and joins them together to form a stack or battery pack.
The ultrasonic double-sheet control dbk+4 on the gripper ensures that only one layer of foils is gripped at a time. The sensor detects without contact whether there is no layer present, a single layer is present or a double layer or several electrode foils are stuck together. In the event of an error message or incorrect stacking, the stacking process is interrupted and the production process is corrected. Error-free stacking helps to ensure that high-quality battery packs are produced. The non-contact single-layer control also protects the sensitive electrode foils.
