Application of insulating foils to prismatic battery cells – flexible and fast

A self-adhesive plastic foil is applied to the prismatic battery bodies for thermal and electrical insulation. 

The topex labelling unit is characterised by a high degree of flexibility. Since the actual battery cells are produced in different formats, the formats of the corresponding foils also change.

The solution is an endless roll of foil, 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 foil 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.

Customer benefits
