Applications
Vacuum Knowledge • Wafer gripper for extremely fast and gentle handling of wafers
and solar cells in the production processes
• Loading and unloading from stacks and conveyor belts
Vacuum Suction Cups • Exact positioning during the visual inspection and position
measurement allow for on-the-fly breakage detection during the
handling process

• Fully or partially automated production of PV cells with maximum
Special Grippers process stability, production line uptime, cell efficiency and line
output

Vacuum Grip- ping Systems Wafer grippers SWGm Design

container

• Base model version with discharging exhaust air (3) in axial (A) or
Mounting Elements • Suction area geometries available in common cell sizes 125 mm
lateral (S) direction

and 156 mm (5" and 6")
• Optional component (II) for controlled discharging of exhaust air
Vacuum Generators • Modular design with accessories for the mounting of sensors and

modules for suction and damping (I) and a selection of flange
modules (III)
• Minimal overall height through reduced-weight plastic design
Valve Technology System design wafer grippers SWGm • Replaceable contact surfaces
