Analysis of the Motion Mode and Control of the Wire Arrangement Mechanism of an Automatic Winding Machine

The wire arrangement accuracy and coil level shape control of the automatic wire winding machine manufacturer are related to many factors such as the spindle speed control accuracy, the motion accuracy of the wire arrangement mechanism of the automatic wire winding machine, and the incoming wire tension. An example of the design and debugging of a thin wire coil winding machine used by a winding machine manufacturer was analyzed, including the structure, motion mode, and control of the wire arrangement mechanism, as well as the influence of the coil layer shape and layer quality.

The process of winding requires a winding skeleton, consisting of two end baffles, rectangular hollow core columns, and wiring plugs. The requirement for winding the coil on the skeleton is that the layer after the assembly cannot form a drum or concave surface, and the single-sided wires should be arranged neatly and evenly without overlapping.

The basic composition of a thin wire winding machine is similar to the structure of a regular non ribbed winding machine. The drive of the wire feeding mechanism of the winding machine usually uses a stepper motor as the basic driving source, which can be driven by a coupling to rotate the ball screw or by a stepper motor to drive the ball screw through a synchronous toothed belt to rotate. The ball screw is driven by a stepper motor through a synchronous toothed belt. Due to the flexible connection between the stepper motor shaft and the ball screw, the requirements for the positioning surface of the stepper motor seat and the assembly of the ball screw and guide rod can be correspondingly reduced, making the machining of the box hole easier and the movement smoother.

In the process of wire winding, in order to maintain a constant value, the speed ratio between and must change accordingly. Determined by the spindle speed and the size of the winding layer, it remains unchanged during stable operation. Due to changes during the commutation transition process, the commutation control of the wire arrangement mechanism becomes a key issue in controlling the quality of the winding layer.

The windings between the coil layers are stacked against each other, that is, there are two times of stacking on one turn. When winding with a large pitch, the stacking of wires is easy to pass through. When winding with a small pitch, the stacking phenomenon is easy to form when the incoming tension is too high. When reversing, the operation law and angular displacement value of this process should be stable, and the winding of the same layer should not be stacked. The transition time of the winding motor should be controlled, And this process is achieved through software control of a stepper motor.
