Improved robot cable

Abstract

The invention discloses an improved robot cable, which comprises a cable core, wherein the cable core is formed by twisting a filling cotton rope at the center and inner, middle and outer three insulating wire core layers towards the left; the inner, middle and outer three insulating wire core layers are concentrically arranged outside the filling cotton rope by employing the filling cotton rope as the circle center and are formed by three kinds of insulating wire cores with different structures; non-woven fabric wraps the outside of the cable core towards the right; and an elastomer PVC sheath layer is extruded outside the non-woven fabric. The improved robot cable has the characteristics of being simple in structure, light in weight, high in flexibility, high in tensile resistance, bending-resistant and torsion-resistant in use and the like.

Description

technical field [0001] The invention relates to the field of electric wires and cables, in particular to an improved highly flexible and torsion-resistant robot cable. Background technique [0002] Industrial robots are the most typical mechatronic digital equipment with high added value and a wide range of applications. As the supporting technology of advanced manufacturing and emerging industries in the information society, industrial robots will play an increasingly important role in future production and social development. important role. Foreign experts predict that the robot industry is a new large-scale high-tech industry after automobiles and computers. According to statistics from the United Nations Economic Commission for Europe (UNECE) and the International Federation of Robotics, the world robot market has a bright future. Since the second half of the 20th century, the world robot industry has maintained a good momentum of steady growth. In the 1990s, the deve...

Problems solved by technology

[0003] At present, domestic industrial robot signal cables and mechanical equipment cables are poor in super softness and high strength, and there is a gap in performance, and high-end cables are still imported in large quantities.

In the prior art, its structure is generally to twist a group of conductors extruded with insulators to form a cable core, and then extrude the outer sheath. This structure cannot provide long-term stable operation for continuous and frequent torsion and bending applications. Guarantee, not suitable for applications that require fast acceleration, fast parallel movement and long-distance movement, because the above applications require cables to have higher flexibility, bending performance and tensile strength
