Why does the automatic winding machine appear jumper and fold

With the development of computer technology and mechanical design technology, the mechanical precision and control system algorithm of automatic winding machine have been greatly improved, which has become an important part of the development of national economy. The improvement of mechanical accuracy is mainly achieved through the development of high quality precision wear-resistant materials, and the winding accuracy mainly depends on the control system and control algorithm.

However, there are problems such as jumpers and wire accumulation at the edge of frame. Each layer of coil is not just pressed on the lower coil. The main reasons are as follows:

(1) There is extrusion pressure between enamelled wires, and there will be relative displacement between enamelled wires in the process of wiring;

(2) With the rotation of the main shaft, the tension of the enamelled wire changes constantly;

(3) With the increase of the number of loop layers, the force between the same layer of enamelled wires and between different layers of enamelled wires also changes;

(4) The permutation line not only satisfies integer circle;

(5) Due to mechanical vibration, the spindle will produce relative stress and relative strain during rotation.

The enamelled wire is not parallel to the edge of the skeleton, but has a certain dip Angle. Assuming that the Angle of inclination is just enough to skip a coil grid, the enamelled wire has reached the skeleton edge through the layered arrangement of 9 grids, so that when the next grid is wound, the next coil will be squeezed, with the possibility of skipping. Therefore, the traditional winding machine uses the wire before and after arrangement into an integer circle, and each layer of wire in the same direction of the speed and the number of turns arrangement will appear jumper and overlapping line.
