BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Figure 1 This is a schematic diagram of the main structure of the present invention; Figure 2 for Figure 1 A partial enlarged schematic diagram of part I; Figure 3 A schematic diagram of the structure for winding the wires of the drawn part with wire material; Figure 4 Schematic diagram of part of the structure after the wire is repaired by covering the sheath. DETAILED DESCRIPTION

[0013] Refer to the attached Figure 1-4The wire insulation exposure monitoring and repair production line includes a spark tester 1. The wire 18 passes through the spark tester 1 for a preliminary leakage test. The side outlet of the spark tester is provided with a line drawing structure on the surface of the wire. Once the spark tester detects leakage, the line drawing structure draws a certain length of line on the surface of the wire. The rear side of the spark tester is provided with a wire wrapping device and a hot melt pressing device. The spark tester, the line drawing structure, the wire wrapping device and the hot melt pressing device are all connected to the controller. The wire wrapping device covers the wire marking position with repair material, and the hot melt pressing device hot-melts the repair material coated on the wire and fuses it with the surface of the wire to repair the leakage position of the wire.

[0014] The line drawing structure includes a line drawing pen 2, one end of which is hingedly connected to the side wall of the spark tester, the tip of the line drawing pen faces the surface of the wire, and the side of the line drawing pen is hingedly connected to the side wall of the spark tester through a first electric telescopic rod 3. The first electric telescopic rod is connected to the controller. When the spark tester detects a leakage location, it sends an instruction to the first electric telescopic rod after a specified time. The first electric telescopic rod retracts so that the tip of the line drawing pen contacts the surface of the wire to draw a line of a certain length.

[0015] The wire wrapping device includes an annular guide rail 4, which is installed on a linear guide rail 5 below the wire through a first powered slider. The wire passes through the center of the annular guide rail, and an annular slider 6 is installed on the annular guide rail. A power device for driving the annular slider to rotate is provided on the first slider. A guide groove 7 opened in a radial direction is provided on the side of the annular slider, and a second slider 8 is provided in the guide groove 7. The second slider is connected to the side of the annular slider 6 through a second electric telescopic rod 9. A feeding box 10 is fixedly installed on the side of the second slider, and a feeding box 11 is provided on the side of the feeding box. A hot-melt wire roller is provided in the feeding box, and an array of powered feeding clamping wheels 13 are provided in the feeding box. An inlet is provided at the outlet of the feeding box corresponding to the feeding box, and an outlet is provided on the side of the feeding box facing the wire. The free end of the wire on the hot-melt wire roller in the feeding box enters the feeding box through the inlet and emerges from the outlet. The part of the wire located in the feeding box is clamped by the array of feeding clamping wheels, and a hot-melt cutting device is provided outside the outlet of the feeding box.

[0016] The hot melt cutting device includes third electric telescopic rods 12 arranged on both sides of the outlet. The movable rod ends of the third electric telescopic rods 12 are fixedly provided with electric heating cutting blocks 14. The two third electric telescopic rods are extended at the same time so that the two electric heating cutting blocks 14 are close to each other, which can cut off the extended wire material and heat the end of the wire material to a molten state.

[0017] A camera 17 is set on the inner side of the annular slider. The camera 17 observes the surface of the wire at all times and transmits the observed image to the controller in real time. The controller analyzes the image and recognizes it. When a drawn line is recognized, the wire wrapping device starts working to achieve more precise control.

[0018] When the initial position of the marked part on the wire is identified and moved to the outlet of the feed box, the first slider moves at the same speed as the wire, and the two electric heating blocks 14 approach to heat the end of the wire to a molten state, and then the feeding clamping wheel rotates to make the end of the wire in a molten state contact with the surface of the wire and the two are bonded together, and then the power device drives the annular slider to start rotating, and at the same time the moving speed of the first slider is reduced, so that the wire wraps around the marked part of the wire. After the winding is completed, the two electric heating blocks 14 approach to cut the wire, and the end of the cut part is also in a molten state and can automatically bond to the surface of the wire, and then the first slider returns to the initial position.

[0019] The hot melt pressing device includes two electrically heated pressing blocks 15 symmetrically arranged on both sides of the wire. Arc grooves are provided on the opposite sides of the pressing blocks 15. The two arc grooves are connected to form a complete cylindrical heating chamber. The two pressing blocks are mounted on the bracket through a fourth electric telescopic rod 16. The bracket is mounted on the linear guide rail through a powered third slider. When the part of the wire covered with the wire material moves between the two pressing blocks, the third slider moves synchronously with the wire. At the same time, the two pressing blocks approach each other and press tightly on the surface of the wire, pressing the wound wire material and then performing hot melting. Figure 4 As shown, at this time, the wire material is fused with the material on the surface of the wire to form a covering sleeve 19, thereby repairing the leakage part.

[0020] Through automated control, this device can mark the leakage position on the surface of the wire, cover the marked position of the wire with repair material through the wire wrapping device, and hot-melt pressing device hot-melts the repair material coated on the wire and fuses it with the surface of the wire to repair the leakage position of the wire.

[0021] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
