The automated electro permanent magnetic fixtures can be used as magnetic grippers at the end of the robotic arm of a truss robot to pick up, lift, load, place, and transport workpieces made of steel materials for automated production lines, serving as an end-of-arm tool. The magnetic grippers not only reduce the time but also cut down the number of operations required to automate and ensure the smooth running of the process. The size, shape and gripping force of the electric permanent magnetic fixtures can be customized according to customer requirements.
