Automatic winding machine function comprehensiveness

Automatic winding machines are becoming more and more comprehensive in function, automating the process from coil production on line, feeder and end winding to coil winding and off line. In terms of the control form of automatic winding machine, it has developed from a single open-loop control to a closed-loop control using DC servo system and AC servo system, where the adoption of AC servo system has become quite common, and a series of products have been formed from single-axis coil winding to multi-axis simultaneous winding of multiple coils. In the form of county-level institutions, depending on the core or skeleton structure of the coils to be wound, shuttle-type automatic winding machines have been developed to adapt to the winding needs of coils with a ring or other closed core or skeleton. With the development of the electronics industry, the demand for coils is growing and the variety of coils is increasing, from large power transformers and generator windings to micro coils for charging, coils for energy saving lamps and coils used in various types of electrical equipment. The use of coils has become popular in all aspects of human life, thus bringing new development opportunities for the automatic winding machine manufacturing industry. Among the various automatic winding machines in use, there are Z-early manual winding, as well as mechanical automatic automatic winding machines and automatic winding machines in the form of mechatronic control. In recent years, the manufacturing level of domestic automatic winding machines and the introduction of automatic winding machine manufacturing level has formed a fully automatic, multi-functional and efficient automatic production capacity.

High-speed automatic winding machine for hollow electromagnetic coils can wind transmission coils, speaker coils, antenna coils and various general coils without skeleton. With reliable performance, high speed and high efficiency, the machine is suitable for mass production in coil manufacturing industry.

This method is influenced by PLC operation, poor synchronization accuracy, large calculation volume, and long CPU processing time, which can lead to uneven winding, pile-up, and collapse, and seriously affect the quality of the finished products. For example, the PLC counts the winding shaft encoder at high speed, and when the count value is reached, the interrupt method is used to control the reverse winding of the spool motor, but the CPU processing time will be affected by lagging errors, which can basically meet the winding requirements at low speed, but for high-speed winding of multi-layer coils, there will be uneven coil ends and the quality of the finished product will be reduced.

The motion control PLC for high-speed automatic winding machine of hollow solenoid coils adopts high-speed dual CPU structure and uses independent CPU to process motion control algorithm, which can realize various motion trajectory control, logic action control, linear/arc interpolation control, etc. The electronic cam function of 20PM motion controller in the high-speed automatic winding machine is a good solution to the winding problem of Uneven winding, stacking, unevenness and other problems are solved.
