The core of modern robots, from robotic arms in factories to assisting doctors in operating rooms, lies in countless rotating joints. So, how can the power that drives joint motion, the precise signals that control its movement, and the media (such as air or fluid) that actuate the end-use tooling be seamlessly transmitted during rotation? Slip rings are the key.
Robot slip rings, also known as rotary joints, are integrated into a robot's rotating joints, wrist units, or base. They stably transmit power, high-speed data signals, sensor feedback, and media like compressed air or hydraulic oil while the component rotates infinitely, making them the "lifeline" that enables complex, continuous robot movements.
Application Components: Robot Controller -> Slip Rings -> Joint Servo Motors/Drivers.
Purpose: Slip rings transmit the high-precision servo motor power and control signals that drive each joint. GuRen slip rings' low resistance and low noise ensure clean power to the motors, enabling precise position, speed, and torque control. They are fundamental to the robot's motion accuracy and repeatability.
Application Components: Joint encoders, torque sensors, end-point sensors -> slip rings -> main controller.
Purpose: The slip ring's high-speed signal channel transmits critical real-time data, such as joint angle, load torque, and visual information, back to the controller at high speed and without delay, forming a closed-loop control system. GuRen's slip rings' excellent signal integrity and anti-interference capabilities are essential for implementing advanced functions such as high-precision force control and vision guidance.
Application Components: Base rotating platforms, robotic arm joints.
Purpose: For collaborative robot bases or joints requiring 360° rotation, as well as the rotating lifting platforms of AGVs/AMRs, slip rings enable continuous transmission of power and signals across rotating components. GuRen specializes in ultra-thin, lightweight, and low-torque slip ring designs to meet the stringent requirements for flexibility and safety in human-robot collaboration.
