Gripper for robot arm for contactless retaining silicon based wafer during manufacturing of solar cell of photovoltaic system, has suction point formed as central suction point and another suction point formed as auxiliary suction points
The gripper has suction points arranged on a carrier device (10) and applied with low pressure, where one of the suction points is formed as a central suction point and another suction point is formed as four auxiliary suction points. The auxiliary suction points are arranged equally spaced to the central suction point. The central suction point includes a suction head (20), and a suction head retainer (22) is formed in the carrier device. The suction head is rotatably held in the suction head retainer around a longitudinal axis (36). An independent claim is also included for a method for transporting a silicon based wafer by a gripper.
