The precision of winding machine and automatic winding machine is related to many factors, such as the precision of spindle speed control, the precision of winding machine, the motion precision of winding mechanism and the incoming tension. This paper analyzes the structure, motion mode and control of the winding mechanism, the influence of the coil layer shape and layer quality by using the design and debugging examples of the winding machine.
1. Winding mechanism of winding machine
As shown in the figure, the winding framework is composed of baffle at both ends, rectangular hollow center post and wiring plug. The requirements for the winding on the framework are: the layer behind the assembly cannot form a drum shaped surface or a concave shaped surface, and the single-sided lines shall be arranged orderly and evenly without overlapping.
2. Wire arrangement mechanism of winding machine
The basic composition of the fine wire winding machine is similar to that of the ordinary non arris winding machine. The driving of the wire feed mechanism of the winding machine usually uses the stepping motor as the basic driving source, which can be driven by the coupling or by the synchronous toothed belt. In this paper, the ball screw is driven by the step motor through the synchronous toothed belt, and its structural diagram is shown in Figure -. Because of the flexible connection between the step motor shaft and the ball screw, the requirements for the positioning surface of the step motor seat and the assembly of the ball screw and the guide rod can be reduced accordingly, so that the box hole processing is easy and the movement is more smooth.

Motion analysis of winding coil
When the coil is wound, the motion law of the line is as shown in the figure.
It can be seen from this formula that in the process of on-line winding, if the value is to remain unchanged, the speed ratio between and must change with each other. Determined by the speed of the spindle and the dimension of the winding layer, it remains unchanged during the stable operation. Because of the changes in the commutation transition process, it changes in the commutation transition process. Therefore, the commutation control of the wire arrangement mechanism becomes the key problem to control the quality of the winding layer.
The winding between the coil layers is overlapped with each other, that is, there are two overlaps on one turn. When winding with a large pitch, the overlaps of the line and the line are easy to pass through. When winding with a small pitch, the incoming line tension is too large, which is easy to form a stacking phenomenon. When reversing, it is reduced from the positive steady-state value to the negative steady-state value, and the operation law and angular displacement value of this process should ensure that the reversing is stable, and the winding at the same layer is not overlapped For winding, it is necessary to control the transition time of the winding motor, which is realized by controlling the step motor with software.
The hardware structure and software design of the control cable arrangement mechanism. The hardware structure system is composed of a single-chip microcomputer. It has a programmable erasable read-only memory and a wire erasing 34567. It is compatible with the industry standard, 8-instruction system and pins, and is internally integrated with a watchdog.
