Application of double-sided adhesive spacers

Double-sided adhesive spacers are applied to the prismatic battery bodies to ensure a defined distance between two battery cells. 

The topex labelling unit is characterised by a high degree of flexibility. Since the actual battery cells are produced in different formats, the lengths of the corresponding spacers also change. The solution is an endless roll of spacers, which is cut to the appropriate size inline as part of the process. A special CO2 laser with a corresponding cutting head is used for this purpose. The separated spacer sections are then transferred to the battery body via a two-axis pick-and-place linear handling system with an integrated vacuum suction plate. This technology achieves the required cycle time of approx. 3 seconds. An online splicer with upstream material storage ensures continuous operation without downtime.
