On-line detection system for film thickness on surface of enameled wire

Abstract

The invention discloses an on-line detection system for the film thickness on the surface of an enameled wire, and relates to the field of thickness detection. The on-line detection system comprises a detection ring and a thickness monitor, wherein the thickness monitor is located on the inner wall of the detection ring; the detection ring sleeves a cable; the bottom end of the cable extends out of a sealing box and is wound on the edge of a setting-out roller; the top end of the cable bypasses guide rollers at the bottom and the top of the sealing box and is wound around the edge of the winding roller; the winding roller is fixedly connected with a rotating shaft of a driving motor; a paint repairing device is arranged at the position, located above the detection ring, of the outer portion of the cable; and a polishing device for polishing redundant paint on the edge of the cable is arranged at the position, located above the paint repairing device, of the outer portion of the cable. According to the on-line detection system, the film thickness of the cable can be detected through the thickness monitor on the inner wall of the detection ring, and meanwhile, the paint repairing device and the polishing device are arranged to conduct remedy treatment on the stage which does not meet the thickness requirement of the cable, so that the film thickness on the cable meets the national standard requirement.

Description

technical field [0001] The invention relates to the field of thickness detection, in particular to an online detection system for paint film thickness on the surface of an enameled wire. Background technique [0002] Enameled wire is a wire covered with an insulating film. Its production process can be summarized as: unwinding → annealing → painting → baking → cooling → winding. During the painting and baking process of enameled wire, problems such as surface defects and uneven paint film thickness are prone to occur, also known as paint film defects, which have a negative impact on the insulation performance of enameled wire. In order to ensure the reliability of the insulating layer, it is necessary to perform linear detection of the paint film thickness in real time. [0003] The paint film thickness detection systems in the prior art all adjust the oven temperature, enameled wire transmission speed and paint film viscosity in time when the detected paint film thickness ...

AI Technical Summary

Problems solved by technology

[0003] The paint film thickness detection systems in the prior art all adjust the oven temperature, enameled wire transmission speed and paint film viscosity in time when the detected paint film thickness is not within the preset range, and the wires whose paint film thickness does not meet the requirements The cable is no longer subjected to follow-up processing and is directly put into use. Obviously, this will make the thickness of the cable vary. The position where the paint film is thinner will affect the insulation performance of the cable, and the position where the paint film is thicker will be different from that of the film. The junction of the thin position will easily cause the breakage of the paint film
