Vacuum enables precise handling of battery cells with high reproducibility. Gripping systems and vacuum generators support manufacturing processes and increase efficiency. One example: The magnetic gripper SGM-SV-BY from Schmalz moves charged and uncharged cylindrical cells with a diameter of 46 millimeters. It grips them either from the top or the bottom. The SGM is suitable for both cell production and module assembly. Its high holding force makes handling cylindrical cells reliable even in fast pick-and-place processes. It can be precisely positioned through the guiding rails. Schmalz uses gripping elements made of insulating plastic – this prevents short circuits.
The gas spring FSTImc securely grips sensitive workpieces like battery foils thanks to its very soft damping spring. It also compensates for uneven component heights and warping – without additional control effort. When handling components of different sizes, the use of integrated flow valves is recommended to securely close unoccupied suction points. For porous workpieces, correspondingly integrable flow restrictors take on this function.
This allows users to achieve maximum flexibility in minimal space. Due to its compact design, the gas spring also fits into tight production environments, and its construction protects it from dirt and mechanical influences. A vacuum-conducting profile or a rigid hose connection for load-free movement supplies it with vacuum.
The FLGR surface gripper moves metallic and graphite bipolar plates at a fast pace. At the trade fair booth, it stacks membrane electrode units and bipolar plates precisely with the help of a robot – a central step in the manufacturing of fuel cells. For this, it aligns the components exactly without affecting the sensitive surfaces.
Compact ejectors provide vacuum at the right place. They can be easily integrated into automated systems and save space. Thanks to their low weight, the SCPSb BY / SCPSc BY / SCPSi BY series is suitable for both movable robotic arms and linear axes. Users can realize dynamic pick-and-place applications with very short cycle times, for example in fully automated small parts handling. The highlight of the series is that it contains very little copper, nickel, and zinc, as these elements can render batteries unusable.
Thanks to the integrated Eco nozzle technology and the air-saving function, the ejectors operate highly efficiently.
