A European company was looking for a specialist magnetising system to magnetise assemblies to saturation. The 25mm long assemblies consists of two Neodymium Iron Boron magnets separated by a steel bar and moulded over with plastic.
The magnetising system had to process four magnet assemblies every 1.25 seconds.
To meet the magnetising need, a special air cored four column magnetising coil was developed to allow gravity to feed the parts from overhead bowl feeders. The feeding of parts was controlled by pneumatic clamps together with component level sensors. Heat build-up in the magnetising coil was dissipated using compressed air.
A mechanism was incorporated below the coil to allow 100% testing of each part and either rejected via a deflector gate or passed and placed onto a steel exit conveyor to keep the parts orientated.
The system included an M4kJa magnetiser for magnetising the assemblies and an IFM01 Integrated Fluxmeters to measure the magnetic strength of each magnet.
The design had to take into consideration continuous development where each magnetiser would have to support two mechanical handling systems in the future.
