The complete control cycle of how the automatic transformer coil winding machine is realized

1 The working principle of servo system

The servo driver in the automatic winding machine control system is the core component of the automatic winding machine servo system, which plays the task of controlling the automatic winding machine and conveying the lineup instructions. The automatic winding machine control system and the winding machine jointly form a complete closed-loop servo mechanism, as shown in Figure 1. The number of motor pulses generated by the winding machine work can be first transmitted to the servo driver through the code in the control system, and by By comparing the operation with the preset pulse value, the position of the winder can be correctly identified and recognized. In this way, the positioning accuracy of the winding machine can be effectively improved, and at the same time, the system can receive the input pulse of the PLC well and convey it to the winding machine to realize the complete control cycle.

2, automatic winding machine servo system performance indicators

Comprehensive measurement of the design requirements of this lineup system, Yismac believes that the more ideal choice is the low inertia winding machine, with which the driver is selected with an input voltage of three-phase 230V or single AC230V, into the power frequency of 20/60HZ, for the winding machine below 0.2KW, the period position signal has three input modes, respectively, pulse – direction, A/B pulse string. Main technical parameters: the rated output power is 0.2ICW; the rated output rotation know 0.64Nni, Z large output rotation know 1.9Nm: rated speed is 3000r/min.

1、Determination of design scheme

The type of winding machine is determined from the type of core or skeleton of the winding coil. A shuttleless winding machine is used for linear or open skeleton to complete the winding of the coil; a shuttle winding machine is used for toroidal or closed skeleton. Shuttle winding machine shuttle is generally a round open shuttle, winding before the skeleton set on the round shuttle, according to the length of the required line section will first wind the line on the shuttle, turning the shuttle and the skeleton can be wound on the skeleton, the transmission of the skeleton more friction wheel transmission, the shuttle generally uses gear transmission, this form of transmission shuttle winding machine in the wiring accuracy, accuracy requirements are not high, if the wiring If the wiring accuracy requirements are high, other forms of transmission should be used. Shuttle winding machine in the design of other issues to be considered such as: the length of the line sizing issues, line tension, cutting, clamping and mechanical mechanisms on the transmission can be designed according to conventional design methods.

The main material of the automatic winding machine processing operation is enameled wire, and the wire needs to be transported from the original barrel to the winding axis through different over-wire devices throughout the process, with different functions and types of tension over-wire mechanisms configured according to different wire characteristics.

Let’s talk about its types first. Our common over-wire types are mainly parallel, vertical and compound over-wire mechanisms, which mainly have relatively big differences in structure, and according to the differences of models, there are electronic servo type, electromagnetic control type and mechanical type which are commonly used configurations.

These common configurations are used in our common automatic winding machines; parallel over-wire for flat copper wire winding processing, vertical over-wire for common round wire processing operations, for some special material wire using the composite over-wire mechanism can keep the tension constant and smooth over-wire.
