Electric rotary table is a mechanical device that achieves accurate rotational motion through electric drive, widely used in industrial automation, precision testing, optical instruments, semiconductor manufacturing, scientific research experiments and other fields. It can complete angle adjustment, positioning, or continuous rotation tasks with high precision, high repeatability, and controllability.
Electric rotary tables usually use stepper motors, servo motors, or DC motors as the driving system, combined with harmonic reducers, planetary reducers, and other reduction devices to improve positioning accuracy and torque output. The encoder is used to provide feedback on the current angle position, achieve closed-loop control, and ensure high-precision positioning. In addition, the electric rotary table adopts high-precision bearings to reduce friction and return errors, ensuring the stability and accuracy of rotation.
power system
Electric motor: As a power source, stepper motors or servo motors are usually used to provide stable torque output.
Transmission device: including worm gear, synchronous belt, gear, etc., which converts the rotational kinetic energy of the motor into the rotational motion of the platform. For example, worm gear transmission has high precision and self-locking properties, making it suitable for scenarios that require high loads.
Equipped with overload protection, emergency stop button, and limit switch to prevent equipment damage or personnel injury. For example, when the rotating platform encounters abnormal resistance, the system will automatically shut down and sound an alarm.
Application field
Industrial automation: Electric rotary tables are commonly used for robot joints, automated assembly lines, material sorting, etc., providing high-precision position control and motion execution.
Optics and Photography: In camera gimbals, laser scanners, and microscope rotating tables, electric rotating tables ensure stable rotation and accurate positioning of the equipment.
Semiconductor manufacturing: used for wafer inspection, chip packaging, alignment of lithography machines, etc., to ensure micrometer level precision operations.
Research and Testing: In astronomical telescopes, spectrometers, and material mechanics testing, electric rotary tables provide a stable rotating platform that supports high-precision measurement and analysis.
