The Movement Mode and Control Analysis of the Wire Arrangement Mechanism of the Automatic Winding Machine
The winding accuracy of the automatic winding machine of the winding machine manufacturer is related to many factors such as the control of the shape of the coil layer, and the movement accuracy of the winding mechanism of the automatic winding machine and the tension of the wire in the spindle speed control accuracy. Winding machine manufacturers use fine wire coil winding machine design and debugging examples, the structure, movement mode and control of the wire winding mechanism, the influence of coil layer shape and layer quality are analyzed.
The winding process requires a winding skeleton, which is composed of baffles at both ends, rectangular hollow columns and wiring plugs. The requirements for the coils wound on the skeleton are: the layer after the assembly cannot form a drum surface or a concave surface. Single-sided lines should be arranged neatly and evenly, and there should be no overlap.
The basic composition of the fine wire winding machine is similar to the structure of the ordinary non-rib winding machine. The winding machine's wire feed mechanism usually uses a stepping motor as the base drive source, and can use a coupling to drive the ball screw to rotate Or adopt two forms in which a stepping motor drives the ball screw to rotate via a synchronous toothed belt. The ball screw is driven by a stepping motor through a synchronous toothed belt. Due to the flexible connection between the stepping motor shaft and the ball screw, the requirements for the positioning surface of the stepping motor seat and the ball screw and guide rod are required. The assembly requirements can be reduced accordingly, so that the box hole processing is easy, and the movement is smoother.
In the coil winding process, if the value is to be kept constant, 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. Because of the change during the commutation transition, the change occurs during the commutation transition. Therefore, the commutation control of the arranging mechanism becomes the control The key issue of quality at the bypass level.
The windings between the coil layers are overlapped, that is, there are two overlaps on one turn. When winding with a large pitch, the overlap between the wire and the wire is easy to pass. When the pitch is small, the incoming wire tension is too large. It is easy to form a stacking phenomenon. When commutation, the value decreases from the positive steady state value, and then rises to the negative steady state value. The operation law and angular displacement value of this process should be commutation smoothly, and the winding coils of the same layer should not be overlapped. It is necessary to control the time of the transition process of the arranging motor, and this process is realized through the software control of the stepping motor.
