Soft cable used for industrial robot

Abstract

The invention discloses a soft cable used for an industrial robot. Every two of eight metal conductor units are intertwisted to form first to fourth symmetric insulation wire pairs, and each symmetric insulation wire pair is wrapped by a first polytetrafluoroethylene band, the first to fourth symmetric insulation wire pairs are intertwisted on the outer surface of an aramid fiber reinforcement piece to form a cable core. A cotton fiber wire is coiled on the outer surface of a second polytetrafluoroethylene layer to form a buffer sliding layer, and the direction of coiling the cotton fiber wire is opposite to the direction of intertwisting the first to fourth symmetric insulation wire pairs. An oversheath wraps a third polytetrafluoroethylene layer. The diameter of the aramid fiber reinforcement piece is 190-210D. The diameter ratio of a first copper alloy conductor to a second copper alloy conductor is 10:6-8. The soft cable is soft and stretch-proof, cannot generate frictional static, and can enable the electromagnetic wave to be uniform on the conductor surface in signal transmission after being moved frequently, so that the electromagnetic distortion is reduced, and the attenuation value is lowered.

Description

technical field [0001] The invention relates to a robot cable, in particular to a flexible cable for an industrial robot. Background technique [0002] With the continuous development of my country's economy and society, the country pays more and more attention to the technology of replacing manual operation with machinery, and the continuous development of my country's future technology, intelligent industry and power industry will bring unprecedented development prospects for robotic arms / manipulators. Due to The operating environment of the manipulator varies widely, which requires that the cables used with the manipulator must have excellent electrical properties, while taking into account superior physical and mechanical properties. [0003] At present, the domestic special-purpose manipulator cables have a short service life due to the softness and wear resistance of the cables, and these cables cannot withstand mechanical external forces. When the cable is subjected t...

Problems solved by technology

In the case of repeated bending of the cable, it poses a greater challenge to the bending performance. The commonly used steel wire may break, so that it cannot play the role of load-bearing and tensile resistance. The broken steel wire may also puncture the insulation or sheath. cause an accident
