Combination cable for industrial automatic robot arm

Abstract

The invention discloses a combination cable for an industrial automatic robot arm, and the cable comprises a cable core and a carbon fiber nylon woven outer protective layer coated outside the cable core; the cable core is formed by twisting a power cable, a signal cable and a protective gas pipe; the power cable comprises a first copper conductor, a first polyester film layer wrapped outside the first copper conductor and a chloroprene rubber sheath layer wrapped outside the first polyester film layer; the signal cable comprises a flexible polyvinyl chloride sheath, a shielding layer, a second polyester film layer and a signal core body which are sequentially arranged from outside to inside, and a filling layer is arranged in a gap of the signal core body. The cable is formed by combining the power cable, the signal cable and the protective gas pipe, installation is easy, the defect that the cable is loose during installation is reduced, unified protection is facilitated, the installation space is saved, the flexibility and torsion resistance of the cable are greatly improved, the use requirement can be completely met, the cost performance is high, and conversion of scientific and technological achievements is achieved.

Description

technical field [0001] The invention belongs to the technical field of robot cables, and in particular relates to a combined cable for an industrial automation robot arm. Background technique [0002] As the industrial scale of industrial robots grows, it is the general trend for robots to replace labor and domestic robots to gradually replace imported robots. The current robot cable is composed of signal detection transmission line and power control line separately, which increases the difficulty in the installation process, and also occupies a larger space, which also increases the cost to a certain extent. [0003] As an important connecting part of industrial robots, robot cables directly affect the service life of robots. Under the condition of high-speed torsion, the traditional robot is easy to cause the problem of cable core breakage, which greatly reduces the service life of the cable. [0004] At present, there are few types of robot cables, and there are still m...

Problems solved by technology

Under the condition of high-speed torsion, the traditional robot is easy to cause the problem of cable core breakage, which greatly reduces the service life of the cable

[0004] At present, there are few types of robot cables, and there are still many technical requirements that cannot be met at the same time. They have good flexibility, but the cables cannot be worn for a long time, which affects the service life of the cables; cables that can be worn for a long time generally have soft properties. It is not very good. It is often constrained by some conditions that require the cable products to have high flexibility and long-term wear resistance without affecting the service life of the cable, which greatly affects the company's economic benefits.

[0005] The traditional robot cable production technology has the following problems: 1) The signal line and the power transmission line are laid separately, which takes up a lot of space; 2) The high-speed torsion resistance is poor; 3) The insulation and sheath flexibility are poor; 4) Wear resistance, oil resistance, Poor corrosion resistance; 5) Inconvenient installation and replacement
