Problems solved by technology

This method mainly has the following disadvantages: 1. It is necessary to wait for the finished product line to be taken off the line before it can be taken out for inspection, which affects the normal production and causes a lot of waste. It can reflect the continuity of the paint film of the 30m finished line, but for the finished line with a shaft of tens of thousands of meters or even hundreds of thousands of meters, this method has certain limitations

Abstract

The invention relates to a high-pressure paint film continuity tester, which comprises a high pressure test head, a direct-current high pressure generator, a signal detection circuit, a processing circuit and a counting instrument, wherein the high pressure test head consists of a bracket, left and right guide wheels fixed on the bracket, and a creaser wheel positioned in the middle of the left and right guide wheels; and the creaser wheel or the left and right guide wheels is / are fixed on the bracket through a vertical displacement adjusting device. The vertical position between the creaser wheel and the guide wheels on the high pressure test head is adjustable, so continuity online detection of enameled wires and paint films can be realized, detection materials are not dissipated, and the test cost is reduced; and the tester has a simple structure, and the positions of the creaser wheel and the guide wheels are convenient to set.

Description

technical field [0001] The invention relates to a high-pressure paint film continuity tester for detecting the continuity of the paint film of an enameled wire. Background technique [0002] The continuity of the paint film is an important performance reflecting the quality of the enameled wire, which directly affects the quality of the finished enameled wire, and indirectly affects the inter-turn voltage of the winding coil and other properties. The current general test method is to use a high-voltage paint film continuity tester for detection. This tester is usually composed of a wire-feeding device, a wire-passing guide wheel, a high-voltage test head, a wire-receiving device, a DC high-voltage generator, a signal detection circuit, and a processing unit. Composed of circuits and counting instruments, the high-voltage test head is generally composed of a pair of guide wheels and a crimping wheel located in the middle of the pair of guide wheels. On the crimping wheel, on...
