A highly wear-resistant robot cable

Abstract

This invention discloses a highly wear-resistant robot cable, comprising an outer sheath and nineteen conductors and six elastic cords encased within the outer sheath. One conductor is located at the center as the main wire, six conductors are spirally wound around the main wire to form a second coil layer, six elastic cords are spirally wound around the second coil layer, and twelve conductors are spirally wound around the second coil layer to form another second coil layer. This invention, through its structure of a central main wire, double-layer spirally twisted conductors, and elastic cords, enables the cable to exhibit excellent wear resistance, bending resistance, and torsional resistance in dynamic environments, extending its service life and improving the stability of signal transmission, making it suitable for high-frequency motion robot systems.

Description

Technical Field

[0001] This invention relates to the field of robot cable technology, specifically to a highly wear-resistant robot cable. Background Technology

[0002] Robot cables are frequently bent, twisted, and dragged in industrial automation, making them susceptible to mechanical wear and fatigue fracture, which reduces their lifespan and signal transmission stability. Existing cables mostly use a single sheath or a simple stranded structure, which lacks sufficient wear resistance and torsional strength, making it difficult to meet the high-frequency, multi-directional movement requirements of robots. Summary of the Invention

[0003] The purpose of this invention is to provide a highly wear-resistant robot cable, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high wear-resistant robot cable, comprising an outer sheath and nineteen conductors and six elastic cords wrapped within the outer sheath, characterized in that: one conductor is located at the center as the main line, six conductors are spirally wound around the main line to form a first coil layer, six elastic cords are spirally wound around the first coil layer, and twelve conductors are spirally wound around the elastic cord layer to form a second coil layer.

[0005] Preferably, the wire includes a tin-plated copper conductor and an insulating layer covering the outside of the tin-plated copper conductor, wherein the thickness of the insulating layer is 0.16mm-0.20mm.

[0006] Preferably, the insulating layer is made of fluorinated ethylene propylene copolymer.

[0007] Preferably, the diameter of the tin-plated copper conductor is 1.80mm-1.84mm.

[0008] Preferably, the diameter of the tin-plated copper conductor is 1.828 mm.

[0009] Preferably, the outer sheath is made of polyurethane or PVC material and has an outer diameter of 3.0-0.15 mm.

[0010] Preferably, the elastic cord is made of 200D Kevlar material to enhance the cable's tensile and torsional resistance.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the structure of a central main line, double-layer spiral twisted conductors, and elastic rope, enables the cable to have excellent wear resistance, bending resistance, and torsion resistance in dynamic environments, extending its service life and improving the stability of signal transmission, making it suitable for robot systems with high-frequency motion.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] In the description of this invention, it should be understood that the terms center, longitudinal, transverse (up, down, front, back, left, right), horizontal, vertical, top, inner, and outer, indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms first and second are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] Please see Figure 1 One embodiment of the present invention provides a highly wear-resistant robot cable, comprising an outer sheath layer 7, and internally arranged a main wire 1, a first coil layer 2, six Kevlar elastic cords 3, and a second coil layer 4. The conductor is made of 13AWG tin-plated copper, and the insulation layer is made of FEP material with an average thickness of 0.25mm and a minimum of 0.18mm. The outer diameter is 2.85mm-3.15mm. The cable complies with RoHS standards, has a rated voltage of 300V, a temperature range of -60℃ to +200℃, an insulation resistance of 10Mkm, a bending life of 100,000 cycles, and a torsional life of 300,000 cycles.

[0017] Working principle: In the operation of this invention, when the cable is frequently bent and twisted at the robot joint, the elastic rope layer absorbs stress, the double-layer twisted structure disperses the force, and the FEP insulation layer provides high temperature resistance and wear resistance protection, thereby greatly improving the mechanical durability and electrical stability of the cable.

[0018] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
