Robotic electromagnetic coil system

Robot-Assisted Electromagnetic Coil System

This technology utilizes the multi-degree-of-freedom mechanism of a robot manipulator supporting an electromagnetic coil assembly to precisely adjust the shape and intensity of the magnetic field by varying the coil's position (longitudinal/lateral) and orientation (rolling/yawing).

Conventional electromagnetic coil systems feature fixed coil assemblies, resulting in uniform magnetic field patterns and intensities that limit the control of objects within the field. Adding more coils to address this issue leads to increased equipment size and structural complexity.

This technology employs a manipulator structure comprising a main body, a pivoting arm, a rotating support plate, and a mobile plate capable of lateral movement and rotation. By utilizing cylinders, motors, screws, and gear mechanisms, it enables longitudinal/lateral movement and rolling/yawing control of the coil assembly. Applicable to industrial robots and automation systems, it provides a robot control system that facilitates smooth movement—including longitudinal, lateral, and rolling motions—thereby improving the dynamic movement of objects manipulated by magnetic fields in electromagnetic coil systems.

Key Features:

• Multiple coil assemblies, each equipped with a core, a bobbin surrounding the core, and a coil wound around the bobbin
• A robot comprising an arm that pivots on a main body and a support plate that rotates on the arm
• The coil assembly is supported by a mobile plate that moves laterally and rotates on the support plate
• A structure where the coil assembly's configuration is variable through longitudinal/lateral movement, rolling, and yawing based on robot operation
