Testing and processing machines
We manufacture processing machines for the production of car batteries. The testing, measuring and checking of the functions are essential process steps in battery manufacture.
Testing and processing machines – concept examples
We supply our testing and processing machines to battery manufacturers across the globe. For each individual machine we tailor the design to the customer’s specifications and to the on-site processes.
The machine is used to align the sets and terminals of open battery casings, that is, batteries without caps. Four plants operated by a large battery manufacturer have already been fitted with this machine.
Machine 1 tests the installation position of the cells by means of a short circuit resistance test of the anode and cathode plates within the batteries ...
… in the downstream testing machine, after the anode and cathode plates have undergone the short circuit resistance test again, the internal welds are then inspected.
The non-welded battery terminals are aligned and lubricated at this workstation prior to the mounting of the cap.
The battery can be measured both with a linear potentiometer and by means of a non-contact method using a 2D laser measurement sensor.
The system scrubs the battery terminals of finished batteries.
The battery seal is tested using a high voltage of approximately 10 kV. Insufficient wall thicknesses or leaks will result in a rupture.
In order to be able to trace the individual battery casings, a data matrix code and a plain text code are engraved into the surface of the battery casing. A camera system then checks the legibility of the data matrix code and performs a validity check on the code that has been read.
Finally, the machine greases the battery terminals of the finished batteries.
