INSTRUMENTATION • ELECTRONICSSECTION TITLE
AGVs are vital to the smooth running of warehouses and production floors
the AMR or AGV is quickly ready for use again. However, it requires an operator to carry out the manual change and charge the discharged battery in a charging station. Automatic battery swapping, on the other hand, enables a fully automatic changing process and offers an alternative to manual changing. However, additional infrastructural measures are required for automatic changing, which provides for a changing and charging device next to the AMR or AGV system. Automatic and opportunity charging is another charging solution. It has the advantage that it can be seamlessly integrated into the workflow through good planning. No manual assistance is required and only one charging station is needed, which can be approached by the AMRs or AGVs whenever the opportunity arises without interrupting the workflow. Tis and the ever-increasing charging
currents mean that battery swapping is not required and the automatic and opportunity charging solution is being used more and more.
SMALL COMPONENTS WITH BIG IMPACT
When taking a closer look at the charging process for automatic and opportunity charging, special attention must be paid to the docking facility at the charging station. Stäubli’s core contact technology called MULTILAM ensures a reliable connection offering minimal contact resistance and a high number of mating cycles. Due to its compact shape, the connector requires less space and is lightweight. Te solution can be fully customised to the customer’s application needs of high current transfer, including size, material, and other modules such as
data, Pneumatics, Liquids, and therefore offers high flexibility.
HIGH MISALIGNMENT SOLUTION For the automatic coupling process, the docking facility must be designed to compensate for any misalignment between the vehicle and the charging station connector to enable a smooth charging process. Te market requires compensation up to +/- 10mm, but existing solutions only offer limited compensation. To meet this requirement, Stäubli Electrical Connectors has developed solutions for its connectors that enable this compensation.
