With the continuous advancement of technology, wafer handling robots are gradually achieving higher levels of automation to meet the demands and challenges of the semiconductor manufacturing industry. The harmonic drive reducer, due to its zero-backlash, ultra-high precision (arc-second level), and lightweight characteristics, is commonly used in equipment such as wafer handling arms (Wafer Handler), lithography machines (Lithography), and cleanroom-compatible machinery. The RV reducer gearbox, owing to its high rigidity, high torque, and long lifespan, is frequently employed in the base of load-handling robotic arms. The precision planetary reducer, with its high torque density and compact structure, is widely used in devices such as wafer conveyor belts, indexing rotary tables, and wafer pre-aligners.

The Standard RV Reducer C Series is a precision mechanical reduction device designed with a two-stage closed differential gear system, combining a cycloid pinwheel and planetary gear structure. It features a hollow output shaft and is widely used in industrial robotics.For robotic arms with end loads ≤20 kg, RV reducers are primarily used in base-to-high-load joints (typically Joints 1-4).For robotic arms with end loads >20 kg, all six joints typically use RV reducers.RV reducers are critical transmission components ensuring robotic arm positioning accuracy.
