An electric rotary gripper is a sophisticated automation tool that enables robotic systems to handle objects with rotational motion efficiently. Combined with a rotary gripper actuator, these devices allow multiple orientation adjustments without requiring additional robot movement. DH-Robotics designs these grippers with servo motors to offer precise control over rotation speed, gripping force, and positioning accuracy. This approach reduces dependency on pneumatic or hydraulic systems, providing energy-efficient and sustainable solutions for industrial automation.
Structure and Dual-Motion Functionality
A typical electric rotary gripper consists of a gearing set, position sensors, control circuits, and a DC motor. Through an advanced dual-motion mechanism, the device combines parallel gripping with precise rotational movement. The rotary gripper actuator translates servo motor rotation into linear motion for gripping while simultaneously enabling angular positioning or continuous rotation, depending on application requirements. This unique design eliminates issues such as cable winding in non-standard rotational applications, ensuring smooth and reliable operation.
RGI Series: Precision and Reliability
The RGI Series from DH-Robotics represents the first independently developed infinite servo rotary gripper. Compact yet robust, this series is widely used in medical automation for tasks like rotating test tubes, as well as in electronics, new energy, and intelligent manufacturing applications. Featuring a dual-servo system in a compact 50 × 50 mm body, the RGI Series offers high repeatability, with ±0.02-degree rotational and ±0.02 mm positional accuracy. These grippers and actuators deliver precise force and position control while maintaining stability during complex rotational tasks.
Advantages of Rotary Grippers
Electric rotary grippers and rotary gripper actuators from DH-Robotics support complex tasks by providing compact, precise, and adaptable solutions for modern industrial automation. Their advanced design enables simultaneous gripping and infinite rotation, improving productivity and operational flexibility. With exceptional repeatability and reliable performance, these devices meet the demanding requirements of medical, electronics, and intelligent manufacturing industries, helping businesses achieve higher efficiency and precision.
