Industrial Applications

1. High-Speed Automated Carton Erecting

Integration into the end-of-arm tooling (EOAT) of a packaging robot to grip, open, and position flat-packed cardboard cartons.

Problem Solved

Achieving rapid cycle times in high-volume packaging lines. The integrated 'Electric ejector pulse valve' provides a 0.15s air supply burst to instantly break the vacuum seal, releasing the porous cardboard immediately without the lag inherent in standard vacuum systems. The 'Integrated filter' (≤40 µm) prevents paper dust from clogging the venturi nozzle.

2. Automotive Sheet Metal Press Transfer

Vacuum gripping system for transferring heavy, oily stamped metal body panels between press stages in an automotive assembly plant.

Problem Solved

Secure handling of heavy, non-porous loads under high acceleration. The 'High vacuum' characteristic (85%) ensures maximum holding force on smooth metal surfaces, while the 'Check valve' maintains vacuum pressure even if the air supply fluctuates, preventing dropped parts. The 'IP65' rating protects the unit from the oil mist and industrial grime typical of stamping floors.

3. Photovoltaic Solar Module Assembly

Precision pick-and-place handling of delicate glass solar cells and finished modules during the lamination and frame assembly process.

Problem Solved

Reducing the complexity and weight of the robotic gripper to prevent damage to fragile components. The 'Integrated function' design combines the solenoid valves, filter, and silencer into a single compact unit (350g), eliminating external valve terminals and bulky piping on the robot arm. The 'Closed silencer' keeps the operation quiet in the cleanroom-like assembly environment.
