Robot signal cable

Abstract

The invention discloses a robot signal cable, which is composed of three first composite twisted conductors and three second composite twisted conductors, wherein the diameter of each first composite twisted conductor is larger than that of each second composite twisted conductor; and the first composite twisted conductors and the second composite twisted conductors are arranged at intervals alternatively. An outer sheath layer coats the outer surface of a wrapping belt. Each second composite twisted conductor comprises a large-diameter center copper wire located in the center and six large-diameter outer copper wires twisted on the outer surface of the large-diameter center copper wire. An aramid enhancement rope is arranged in the center gap between the three first composite twisted conductors and the three second composite twisted conductors. The outer sheath layer comprises the following components: ethylene-tetrafluoroethylene copolymer, metallocene polyethylene, polypropylene, ethylene-octene copolymer, maleated ethylene vinyl acetate copolymer, and aluminum hydroxide. The bending-resisting and twist-resisting performance exceeds 60 million times and phenomena of cable deformation and conductor fracture do not happen, and the overall cable can be ensured to have excellent mechanical and physical performance.

Description

technical field [0001] The invention relates to a cable, in particular to a robot signal 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 development of robot products accelerated, with an average annual growth rat...

Problems solved by technology

[0004] 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
