[0002] With the continuous development of industrial production and the wide application of heat treatment technology, the position of heat treatment equipment in the metal processing industry is increasingly important. Heat treatment equipment is used to improve the organizational state and performance of materials, and is a key link to improve the quality and service life of workpieces. The traditional heat treatment equipment auxiliary feeding mode often relies on manual operation or simple mechanical devices, which has the problems of slow feeding speed and low efficiency. This not only affects the overall production efficiency of the heat treatment equipment, but also increases the labor cost and labor intensity. Some existing auxiliary feeding equipment uses mechanical grabbing or simple magnetic attraction. Mechanical grabbing may cause damage to the surface of the workpiece, affecting product quality; while the simple magnetic attraction method has poor adsorption effect when facing non-magnetic materials or irregularly shaped workpieces, and may cause the workpiece to fall, which poses a safety hazard and affects production continuity.
