Lead detection device

Abstract

The invention provides a conductive wire detection device, belonging to the field of wire and cable processing technique. The conductive wire detection device comprises a frame with a table top; the table top is fixedly provided with a detection sleeve seat which is provided with a sliding trough which is matched with a detection sleeve in a sliding way; the center of the detection sleeve is provided with a conductive wire hole; furthermore, the external wall of the detection sleeve is extended by at least one signal contact; at least one side of the table top corresponding to the length direction of the detection sleeve seat is fixed with a signal collector bracket which is provided with a signal collector which is electrically connected with the control switch of a conductive wire coiling device by wires; the signal contact is corresponding to the signal collector. The conductive wire detection device has the advantages that when passing through the detection sleeve, the defective wire and cable drive the detection sleeve because the defective wire and cable can not pass through the conductive wire hole on the detection sleeve; the signal contact on the detection sleeve is contacted with the signal collector; the signal is fed back to the control switch of the coiling device by the signal collector further; therefore, the coiling device stops coiling and the operators carry out the defect processing subsequently.

Description

technical field [0001] The invention belongs to the technical field of wire and cable processing, and in particular relates to a wire detection device. Background technique [0002] As is well known in the industry, after the wire and cable are processed and formed, they need to be tested by a special testing device, for example, after the wire is extruded and coated with an outer sheath, the insulation performance of the wire needs to be tested. The well-known and currently widely used detection means are: an outer sheath damage detector and a wire winding device are equipped at the sheath extrusion machine, and the outer sheath damage detector is used to test the withstand voltage of the wire and cable from the sheath extrusion machine. The condition is detected online and the wire is rewound by the wire winding device at the same time. Once there is a defect in the insulation layer, the outer sheath damage detector will alarm, so that the sheath extrusion machine will sto...

AI Technical Summary

Problems solved by technology

However, in some cases, although the withstand voltage insulation level of the wire meets the requirements, there are inevitably bulges or nodules outside the wire during the process of extruding the outer sheath, which affects the appearance quality of the wire.
