Currently, in the production process of enameled wires, the viscosity of lacquer oil is unstable, or the lacquer thickness is uneven due to the lacquer painting process, that is, the finished outer diameter size of the enameled wires can fluctuate. When the fluctuation is large, the coil size is increased, the coil is not accommodated when being wound, and the phenomenon of excessively high slot filling rate occurs; and the part with too thin paint can generate pinholes, voltage resistance, scratch resistance, chemical resistance and ageing resistance, so that the service life of the enameled wire is shortened, the performance of the enameled wire is influenced, and even the enameled wire is directly scrapped.

However, for the enameled wire, a movable detection frame is generally disposed on the winding path, and a diameter measuring instrument (generally, infrared or laser) is disposed on the detection frame, wherein a diameter measuring area formed by the diameter measuring instrument is shifted along with the movement of the detection frame, and the enameled wire to be detected passes through the diameter measuring area, so that outer diameter information of the enameled wire of the detection position is obtained, thereby facilitating subsequent operation and controlling product quality. However, in the above-mentioned detection process, since the transmission path of the enameled wire does not always maintain stable output, in short, the enameled wire is under tension-free to perform detection, and shake of small amplitude is easy to occur, so that the diameter measurement is performed during the shake process, and a great diameter measurement error exists, and the quality of the whole enameled wire is affected between erroneous judgments.
