AI Technical Summary

⚠Technical Problem

During the motor rotor assembly process, the presence of burrs on the iron core results in one end of the iron core having burrs after assembly, affecting the quality of the rotor product, especially during the winding process, which can easily scratch the wire assembly.

⚗Method used

Design a shaft feeding device to prevent the burrs of the iron core from being exposed. By setting up two sets of iron core storage bins to make the burrs of the iron core face opposite directions, and by using a two-stage feeding method, the burrs are made to face the center, thus avoiding exposure during the winding process.

🎯Benefits of technology

It effectively prevents the core burrs from being exposed, improves the quality of rotor products, avoids damage to the wire assembly, and enhances the overall assembly quality.

Abstract

This utility model provides a shaft feeding device to prevent exposed core burrs, including a frame, a conveying mechanism, a core unloading mechanism, a shaft unloading mechanism, a shaft feeding mechanism, and a rotor unloading mechanism. The conveying mechanism is fixed above the frame. The core unloading mechanism and the shaft unloading mechanism are both fixed on the frame and respectively mounted on the left and right sides above the conveying mechanism. The shaft feeding mechanism is mounted above the conveying mechanism and corresponds between the core unloading mechanism and the shaft unloading mechanism. The rotor unloading mechanism is fixedly located on one side of the shaft feeding mechanism. The core unloading mechanism includes a support frame, a feeding cylinder, a core picking slider, and a core storage bin. The advantage of this design is that by setting two sets of core storage bins to hold cores facing opposite directions, and by feeding the cores in two stages, the burrs on the cores are all facing the center. During the winding process, there are no exposed burrs on the cores, thus preventing damage to the wire assembly and improving the quality of the rotor.
