The structure design of the end picker for the automobile control arm stamping production line

In the process of stamping, production and transportation of automobile control arm, the surface of the workpiece can not be adsorbed due to the oil stains on the surface of the workpiece. The traditional vacuum chuck can not be adsorbed. The electromagnetic chuck will generate heat for a long time and cause the magnetic force to decline, resulting in reduced reliability and causing the workpiece to fall off. The principle uses NdFeB material to design a new type of electric permanent magnet end picker. When the power is cut off, it relies on the magnetic force of the permanent magnet to adsorb. After the robot transfers the workpiece, the coil around the reversible material is passed through an electric current to generate an electromagnetic field opposite to the permanent magnet. To counteract the magnetic force, the workpiece is separated, the end suction cup of the end picker is designed according to the quality of the workpiece and the contact area, and ANSYS ELECTRONICS is used for modeling analysis and verification. The data shows that the device can meet the needs of the car control arm grasping and handling work. It provides a new idea for automatic production line of automobile control arm.
