High-flexibility anti-torsion composite cable for robot

Abstract

The invention discloses a high-flexibility anti-torsion composite cable for a robot. A control wire group, a plurality of power wire cores and a cotton silk filling rope are twisted to form a cable core, and the cable core is sequentially wrapped by a first shielding protection layer, a shielding layer, a second shielding protection layer and an external sheath from the inside to the outside. The power wire cores respectively consist of a conductor and an insulating layer wrapping the conductor. The control wire group is formed by the twisting of four control wire cores, and the control wire cores respectively consist of a conductor and an insulating layer wrapping the conductor. The cotton silk filling rope is formed by the twisting of the cotton silks. The cable is enabled to be flexible and elastic and to be resistant to bending and torsion through the development of a new material, a cable structure and the optimization design of the manufacturing technology. The cable can be widely used in the high-frequency and high-speed work environments of an industrial robot, can be widely used in occasions of frequent bending and moving, is high in resistant to wear and oil, and is long in service life. The number of bending and torsion times can reach 20,000,000.

Description

technical field [0001] The invention belongs to the technical field of cables, and specifically designs a highly flexible anti-torsion composite cable for robots. Background technique [0002] The "Industry 4.0" concept proposed by the German government is called the fourth industrial revolution, which has triggered a new round of industrial transformation competition on a global scale. In the future, robots, industrial automation, and intelligence will be popularized in more and more fields. According to the "Robot Industry Development Plan" issued by the Ministry of Industry and Information Technology and other ministries and commissions, by 2020, the annual sales revenue of service robots in my country will exceed 30 billion yuan, and will continue to maintain a high growth trend with the process of industrial automation. The robot cable is the "vessel" and "nerve" of the robot, and is an important part of the robot. Special cables for robots with high flexibility, bend...

AI Technical Summary

Problems solved by technology

Most of the high-performance robot cables for industrial robots still rely on imports, and the robot cables produced by most domestic enterprises can only be used in some non-critical parts with low torsional and bending frequencies, small amplitudes, and slow speeds

At the same time, foreign companies keep the robot cable manufacturing technology strictly confidential, and domestic companies do not have corresponding robot cable standards for reference.
