Solar Cell Wafer Gripper SWG

Large contact area between wafer and gripper with maximum holding force
» High speed, high accuracy handling for cycle times < 1 second
Moderate air consumption
» Less operating cost than Bernoulli grippers
Low vacuum level
» Minimal torsional forces and minimal conchoidal fracture risk
High throughput vacuum generation
» Reliable gripping and handling even of deformed and broken wafers
Controlled air discharge
» No contamination of working range with silicon dust or fragments
Rapid venting of vacuum chamber
» Precise positioning and very short cycle times
Gripper surface optionally made of PEEK (Polyetheretherketone)
» Minimal surface contamination and reduction of blind spots
Modular concept with various surface materials, sensors, and optional shock absorption elements
» Optional breakage detection through backlit gripper surface

Extremely fast, reliable, precise and gentle handling of silicon wafers and cells
Loading and unloading of stacks and conveyor belts
High accuracy positioning during and after the visual inspection process
“In flight” check for broken wafers during handling
Fully or partially automated production of silicon PV cells with maximum process stability, production line uptime, cell efficiency, and line output
