GRIPPER FOR HOLDING AND POSITIONING A DISC- OR PLATE-SHAPED OBJECT AND METHOD FOR HOLDING AND POSITIONING A DISC- OR PLATE-SHAPED OBJECT

摘要

The invention relates to a gripper (20) for contactlessly holding and precisely positioning a disc-shaped or plate-shaped object (31, 32), which has a holding device (21) for generating a holding force acting essentially perpendicular to the principal plane of extension of the object (31, 32). To this end, the gripper (20) has positioning nozzles (22), which are separate from the holding device (21) and which are provided for generating a positioning force acting essentially parallel to the principal plane of extension of the object (31, 32) by means of a fluid exiting the positioning nozzles (22).
