<p>#CMT# #/CMT# The gripper (10) has a suction chamber (16) including a suction wall (18) i.e. perforated steel plate, with perforations, where the chamber is placed on a workpiece (12). An ejector nozzle (28) is connected to the chamber. An outlet (40) of the nozzle is opened to an outside or into an exhaust air duct. A suction inlet (38) of the nozzle is emptied into the chamber. An outlet opening (26) of the chamber is coaxially arranged at the inlet. The inlet is formed by an opening of a sleeve-like section of the nozzle. A front side of the section is arranged at a distance to a surface of the chamber. #CMT#USE : #/CMT# Pneumatically actuated area vacuum gripper for gripping and separating workpieces i.e. thin, flexible workpieces (claimed) e.g. wafers, foils, and papers. #CMT#ADVANTAGE : #/CMT# The outlet of the ejector nozzle is opened to the outside or into the exhaust air duct, and the suction inlet of the ejector nozzle is emptied into the chamber, thus enabling easy and reliable gripping and lifting of the workpieces defined regarding a position of the workpieces in a process-safe or energy-efficient manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a pneumatically actuated area vacuum gripper. 10 : Pneumatically actuated area vacuum gripper 12 : Workpiece 16 : Suction chamber 18 : Suction wall 26 : Outlet opening 28 : Ejector nozzle 38 : Suction inlet 40 : Outlet.</p> |
