String Gripper SSG for the Gentle Handling of Cell Strings

A gripping device for handling cell strings in the production of photovoltaic systems was needed. The string gripper from Schmalz is attached to a robot, which allows the highly sensitive workpieces to be moved safely and accurately. The string gripper SSG-A is equipped with bellows suction cups that adjust themselves perfectly to the workpiece. The reduced internal diameter of the suction cups prevents parts of workpieces from being drawn in, which prevents the occurrence of any deformation. The elongated sealing lip forms a secure seal even on small areas that are uneven, such as on tab wires. The suction cups are made of the special-purpose material HT1 and leave absolutely no marks on the workpiece.

The high suction capacity of the sting gripper is sufficient to handle workpieces safely even if the surface is not entirely covered or if there are leaks. The low weight of the gripper system allows strings to be handled safely, quickly and accurately.

Thanks to the integrated vacuum generator, it is not necessary to spend time running hoses for the gripper. The string gripper SSG-A can be connected to all standard robot types using a flange adapter.
