Enameled wire is one of the main varieties of winding wire, which consists of two parts, conductor and insulation, the bare wire is softened by annealing, and then coated with lacquer and baked several times. However, it is not easy to produce a product that meets both the standard requirements and the customer's requirements, which is affected by the quality of raw materials, process parameters, production equipment, environment and other factors, therefore, the quality characteristics of various enameled wires are different, but they all have four major properties, namely, mechanical properties, chemical properties, electrical properties, and thermal properties.
The principle of laser cleaning is the use of high-frequency high-energy laser pulse irradiation of the surface of the workpiece, the coating layer can be instantly absorbed by the focused laser energy, so that the surface of the oil, rust spots or coatings occur instantly to be stripped off, high-speed and effective removal of surface adhesions or surface coating cleaning method, and the action time is very short laser pulse, under the appropriate parameters will not harm the metal substrate.
After the first laser cleaning irradiation, the first layer of adhesion on the surface of the enameled wire is cleaned off, revealing a layer of black part, after the second cleaning, the laser cleaning will be cleaned off the black part, it shows the original color of the enameled wire, after the cleaning, it can be clearly seen that the effect of the cleaning, and the laser cleaning of the enameled wire material does not cause damage.
