Enameled wire paint film control method and control device of enameled wire paint film

Abstract

The invention discloses an enameled wire paint film control method and a control device of the enameled wire paint film. The enameled wire paint film control method comprises the following steps of carrying out real-time detection of the line diameter of a line outputted by an enameled wire drying mechanism through a diameter measurement mechanism, transmitting a detected line diameter size abnormality signal to a PLC, and carrying out digital-to-analog conversion of the detected signal through the PLC, sending an analog signal to a speed regulating motor after the digital-to-analog conversion, and controlling the rotating speed of a painting roller by the speed regulating motor so as to control the paint film thickness of the enameled wire. The enameled wire paint film control method andthe control device of the enameled wire paint film have the advantages that the thickness of a paint film can be adjusted in real time, the fluctuation range of the paint film of the enameled wire issmall, the quality of a enameled wire finished product is high, and the rejection rate is low.

Description

technical field [0001] The invention relates to the technical field of enameled wire production, in particular to a method and device for controlling enameled wire paint film. Background technique [0002] At present, intelligence and automation have entered a stage of rapid development, the use of motors is becoming more and more widespread, and the trend of miniaturization and high efficiency of motors is becoming more and more obvious. For the core components of the motor, the requirements for fine enameled wires are becoming more and more refined. At present, the painting method of the production equipment is felt painting, and the control of the thickness uniformity of the insulating layer by felt painting is completed by manually adjusting the number of revolutions of the painting roller after manual measurement, which has poor operability and is harmful to the work. Personnel have higher experience requirements. In addition, the viscosity of the insulating paint wil...

AI Technical Summary

Problems solved by technology

At present, the painting method of the production equipment is felt painting, and the control of the thickness uniformity of the insulating layer by felt painting is completed by manually adjusting the number of revolutions of the painting roller after manual measurement, which has poor operability and is harmful to the work. Personnel have higher experience requirements

In addition, the viscosity of the insulating paint will change with the change of the ambient temperature. The large temperature difference between day and night will lead to a large change in viscosity. The change in viscosity will lead to the change of the amount of paint on the paint roller. The adjustment of the number of revolutions will be very frequent, and the producer will spend a lot of energy to control the change of the insulation layer, and there is a certain hysteresis in the way of manual control. Even after the adjustment, the fluctuation range of the thickness of the insulation layer is large, which is difficult to meet Increasingly refined requirements, a little carelessness will lead to a large amount of waste

Therefore, the existing enameled wire paint film control method and its device have the problems of being unable to adjust the thickness of the paint film in real time, and the fluctuation range of the enameled wire paint film after painting is large, which affects the quality of the finished enameled wire and has a high scrap rate.
