Characteristics

Designed for handling wafers in the vacuum chamber of production line and inspection line.
Double payload and superior cost performance compared to STVHR series.
Compatible with STVHR series and it is possible to replace or upgrade into STVCR series.
Execution of origin search is not required by using the servo motors with absolute encoders.

Magnetic fluid sealing is used for arm joint.
Vacuum sealing: Magnetic fluid sealing and bellows are used.
For cleanliness: 5µm mesh filter installed for exhaust ventilation in the arm.
Twin-arm reduces the wafer swap time.
Motion monitoring is available.
RS232C and parallel photo I/O are standard for control.
AC servo motors with absolute encoders installed in all axes.
High-speed, high-accuracy wafer handlingby S-curved speed control.
AC servo motor or 2-phase pulse motor type is selectable.
Wafer holding: end-effector with passive edge or edge grip type End-effector.
End-effector material: CFRP, Al, ceramic, or others.
Optimal end-effector is selectable according to the carrying object and line layout.

Standard Specifications

Representative specifications of STVCR4190-050-AM.
It can be changed depending on the carrying object and end-effector type.
