TECHNICAL FIELD

[0001] The application belongs to the technical field of motor production, and particularly relates to a three-blade material belt feeding machine for a stepping motor. BACKGROUND

[0002] A stepping motor is an electromotor for converting an electric pulse signal into corresponding angular displacement or linear displacement. After inputting a pulse signal, a rotor rotates an angle or moves forward by one step, and the output angular displacement or linear displacement is proportional to the input pulse number, and the rotation speed is proportional to the pulse frequency. Therefore, the stepping motor is also called a pulse electromotor.

[0003] A three-blade is internally installed in the stepping motor, and the three-blade has the characteristics of small volume and thin thickness, and the thickness is only 0.1 mm and the width is only 10 mm, and the blade is bent. In traditional processing, mechanical feeding will cause the phenomenon of material jamming and stacking, and damage to the three-blade. Therefore, in the existing technology, the feeding mode of the three-blade is manual feeding, which causes waste of human resources in the production process, and manual feeding also has the problem of inconvenient operation, and the efficiency of manual feeding is low, which slows down the overall production rhythm.
