[0002] Enameled wire is a main type of winding wire, which consists of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked for many times. If there are impurities and bubbles accumulated on the surface of the paint film, or if the bare wire itself has burrs, scratches, pits and other defects, these factors will cause the surface of the enameled wire to be uneven, thus forming paint nodules.

The provided clamping spring plays a role of pushing the connecting slider, which can further make the connecting rod 55 and the transmission wheel 50 fit the outer side of the enameled wire, which is conducive to the movement of the enameled wire while driving the transmission wheel 50 to rotate.

[0060] When the present invention is used, the enameled wire to be tested is passed through the testing device, that is, the enameled wire is passed between the multiple groups of arc-shaped feedback plates 201. When there is a paint nub on the outer wall of the enameled wire, the paint nub will smoothly enter between the multiple arc-shaped feedback plates 201 under the guidance of the inclined arc plate 205 due to the protrusion of the paint nub, so that the arc-shaped feedback plate 201 is pushed outward with the enameled wire, and the primary arc-shaped plate 203 is driven by the connecting round rod 202 to squeeze the airbag 301, and the airbag 301 is pressed. When the gas is squeezed, the gas pressure changes, which is sensed by the air pressure sensor 302 and the data is transmitted to the external terminal. The external terminal receives the data and controls the pump body 405 and the electromagnetic valve 403 to open. The pump body 405 sprays the marking liquid in the liquid storage tank 408 to the outer wall of the enameled wire through the secondary connecting pipe 409, the primary connecting pipe 407, the hollow plate 401 and the liquid spraying pipe 402 in sequence, thereby marking the vicinity of the paint nodules, which is convenient for subsequent personnel to check the paint nodules.

[0061] The arrangement of multiple sets of arc-shaped feedback plates 201 can fully detect the paint nodules at different angles on the outer wall of the enameled wire;

[0062] When the air pressure sensor 302 transmits data to the external terminal, the external terminal will record it, so that personnel can determine the positions of all detected paint tumors according to the marks and the records.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
