Robot push rod driving combined cable capable of automatically compensating for bending

Abstract

The invention discloses a robot push rod driving combined cable capable of automatically compensating for bending. The structure of the robot push rod driving combined cable comprises an external protection layer, a bending compensation structure, a cable fixed rack, a copper wire weaving shielding layer, a signal transmission line core and a filling layer, wherein the robot push rod driving combined cable is connected with a fixed device by a cable and is combined with a fixed device sliding block, the tension of each strand of cable core in the cable can be maintained constant after a robotjoint is bent, the situation that a wire core is broken due to excessively large tension or the wire core is extruded due to excessively small tension is prevented, the wear speed of the cable is reduced, and the service lifetime of the cable is prolonged. The cable can be effectively fixed by the cable connection fixed device, the situation that the cable wire core is twisted to puncture an insulation body due to rotation of a robot after bending is prevented, and the working safety of the robot is ensured.

[0002] With the maturity of industrial robot technology, the application of industrial robots has begun to spread rapidly. The complete set of equipment for industrial robot automation production line has become the mainstream of automation equipment and the future development direction. Foreign automobile industry, electronic and electrical industry, engineering machinery and other industries have a large number of The automatic production line of industrial robots is used to ensure product quality and improve production efficiency. However, the current technical considerations are not perfect and have the following disadvantages: 1. The robot can improve the degree of freedom of the robot by bending and rotating the joints during work, and when the joints are bending. , the multi-strand cable is stretched apart, and the outermost wire core on the curved arc receives a larger tensile force, while the innermost wire core has a smaller tensile force and is squeezed, thereby accelerating the wear of the wire core , shorten the service life of the cable; 2. The rotation of the robot joint after bending will easily cause the core wire inside the cable to twist, and then the core wire will break through the insulator, resulting in a short circuit or open circuit, reducing the safety of the cable
