Force measurement and measurement transmission

during the welding of battery cells

  • Multi-channel, universal measuring system consisting of up to 8 instrumentation amplifiers and a fieldbus controller
  • Connection via PROFINET, EtherCAT or EtherNet/IP supports digital and fast measurement data acquisition in real time
  • Highest flexibility due to a instrumentation amplifier for strain gauge, potentiometric, DC/DC and incremental sensors

Task

The poles of individual cells are welded in a vehicle battery assembly system. The poles of the up to 64 cells are connected with electrically conducting busbars using a laser welding procedure. In addition to a high degree of positioning accuracy a defined press-on force during the process must be 100 % guaranteed. In order to reduce the testing and cycle times, a force measurement is carried out at 8 poles in each case within the range of 400 to 500 N simultaneously. Measured value transmission takes place via 8 cascadable bus-capable instrumentation amplifier series 9250 and a PROFINET fieldbus controller model 9251 to a central control unit in real time.
