Description

Technical Field

[0001] The invention relates to the technical field of enameled wire processing, in particular to an enameled wire painting device with a uniformity detection function. Background Art

[0002] Enameled wire is the main type of winding wire. It consists of a conductor and an external insulating film. The external insulating film is painted to solidify the paint liquid on the outside of the conductor, thus forming an insulating film.

[0003] Before painting, the enameled wire is easily attached to dust and other pollutants on the outside. During painting, these pollutants will mix into the paint liquid, causing uneven painting on the enameled wire, thereby affecting the processing quality of the enameled wire. Therefore, it needs to be cleaned.

[0004] In traditional enameled wire painting devices, after a long period of painting, the paint liquid easily deposits on the bottom of the painting box to form paint mud. The traditional enameled wire painting device cannot effectively deal with the paint mud at the bottom, which leads to uneven distribution of paint in the solution and even a decrease in the concentration of the paint liquid attached to the enameled wire, resulting in a decrease in the thickness of the insulating film of the cured enameled wire, thereby affecting the quality of the enameled wire processing.

The power and the number of windings of the two diverter valves 66 and the No. 2 heating pipe 65 are different, so that the No. 1 heating pipe 64 and the No. 2 heating pipe 65 respectively heat the pipes fixed thereto at different temperatures. The power and the number of windings of the No. 1 heating pipe 64 are both smaller than those of the No. 2 heating pipe 65, and the No. 1 heating pipe 64 is smaller than that of the No. 2 heating pipe 65. The drying box 61 is close to the inlet end, and the No. 2 heating tube 65 is located in the middle, so that the enameled wire is first pre-cured through the first air ring 67 to avoid uneven distribution of the paint liquid due to its strong fluidity, and then further cured through the second air ring 67. The diverter valve 66 closest to the outlet end has no heating tube, so that the enameled wire is cooled and shaped through the last air ring 67 to prevent the enameled wire from being over-cured and causing uneven stress distribution. Each diverter valve 66 is connected to the three air rings 67 through a pipeline, so that it can dry three enameled wires at the same time. Each air ring 67 is provided with an annular air outlet 671, and the annular air outlet 671 is arranged in the inner ring of the air ring 67, so that the air flow is evenly blown to the enameled wire to avoid affecting the paint liquid on the enameled wire and causing uneven distribution of the paint liquid.

[0045] By means of a high-voltage tester 72 fixed on a fixing seat 71, a high-voltage test is performed on the enameled wire after painting through the annular probe brush of the high-voltage tester 72, so as to detect whether there are defects in the paint film on the surface of the enameled wire, thereby detecting the uniformity of the paint film. By providing four industrial cameras 73, two of the four industrial cameras 73 pass through the No. 1 rack 74 and the No. 2 rack 75 respectively, so that the four industrial cameras 73 are fixed on the top, bottom, left and right of the enameled wire, so as to perform image detection on the enameled wire, and by comparing it with the qualified enameled wire picture, the uniformity of the enameled wire paint film thickness is detected, thereby judging whether the enameled wire is qualified or not.

Before the enameled wire is painted by the cleaning mechanism 3, the enameled wire is painted by the painting mechanism 4. The No. 1 motor 44 drives the No. 1 painting roller 42 to rotate, so that the bottom of the enameled wire is stained with paint liquid. The water pump 45 sprays paint from the paint spray hole 432 to spray paint on the top of the enameled wire, so that the enameled wire is evenly covered with paint liquid. The No. 2 motor 481 drives the No. 2 sprocket 482 to rotate. The No. 2 chain 483 is mounted on the outside of the No. 2 sprocket 482, so that the No. 2 chain 483 rotates along the two No. 2 sprockets 482, and the scraper 46 moves with the No. 2 chain 483, thereby scraping off the paint mud deposited at the bottom of the No. 1 paint storage tank 411. During the movement of the scraper 46, the gear 472 drives the No. 1 driven shaft under the action of the rack 471. 473 rotates, causing the No. 1 chain 475 to rotate along the four No. 1 sprockets 474, causing the three No. 2 driven shafts 476 to drive the three turbines 477 to rotate, so that the three turbines 477 stir the bottom mud scraped up by the scraper 46 and mix it with the paint liquid above. The excess paint liquid is scraped off by the paint scraper block 5, and the excess paint liquid flows back to the No. 1 paint storage tank 411 from the guide groove 51, thereby avoiding waste of paint liquid. The fan 63 drives the air flow to enter the three diverter valves 66, and blows out air flows of different temperatures through the three air rings 67 to solidify the enameled wire. The uniformity of the enameled wire after shaping is tested by the high-voltage tester 72 and the industrial camera 73. The qualified enameled wire is collected by the wire take-up machine 8, and the unqualified enameled wire is collected after manual repainting.
