Embodiment 1

[0031] like Figure 1-2 As shown, the present invention provides a drag chain line for a high-flexible robot body, including a jacket 1; the jacket 1 is wrapped with three signal wires 2, three filling wires 3 and a cable skeleton 4; the wire The cable skeleton 4 is arranged at the axial center inside the jacket 1 and is divided into several joints 5 in the radial direction; the signal line 2 and the filler wire 3 are axially arranged around the cable skeleton 4 . The signal line 2 is formed by twisting two conductors 7 wrapped with an insulating layer 6 .

[0032] In order to separate the combination of each group of signal lines 2 and filling lines 3, the condyle 5 includes a central shaft 501 and three spacers 502, the spacers 502 are fixed on the sides of the central shaft 501, and the The angles between the separators 502 are all 120°. In order to realize the end-to-end connection between the joints 5, one end of the central shaft 501 is a male head 503, and the other e...

Embodiment 2

[0041]The conductors to be used are drawn through a wire drawing machine, and the conductors are multiple tinned annealed copper wires filled with bulletproof wires; and the heat pipe type return device is used to realize continuous annealing of the drawn conductors; prepare tetrafluoroethylene copolymer as Insulation layer raw material, wrap the heated molten tetrafluoroethylene copolymer on the outside of the conductor, and form a smooth insulation layer after cooling; prepare polyethylene foam and heat it in an extruder, and inject it out of the wire through an injection mold For a single joint of the cable skeleton, after the joints are cooled, connect the joints end to end to form a whole cable skeleton for later use; every two conductors wrapped with an insulating layer are twisted together to form a signal line; Prepare several filler wires for use; insert a signal wire and a filler wire into each wire space of the cable skeleton at the same time, and wrap the filled cab...

Abstract

The invention provides a drag chain line for a high-flexibility robot body. The drag chain line comprises an outer cover. A plurality of signal wires, a plurality of filling wires and a cable framework are wrapped in the outer sheath; the cable framework is arranged at the axis of the interior of the outer sheath and is divided into a plurality of joints in the radial direction; and the signal wires and the filling wires are axially arranged around the cable framework. The drag chain line is simple in processing technology, suitable for various high-degree-of-freedom industrial robot equipment and capable of bearing torsion and bending of different degrees, and external loss borne by the internal signal line is effectively reduced.

Description

technical field [0001] The invention relates to accessories in the field of industrial robots, in particular to a drag chain line for a high-flexibility robot body and a production process. Background technique [0002] The robot body cable is used in multi-joint, high-degree-of-freedom industrial robot equipment. The cable can be designed and customized with a twist angle of ±360 degrees / meter. It is used in the industrial robot body and is widely used as a special servo cable and encoder signal cable for industrial robots. . It is widely used in a variety of industrial robot equipment such as palletizing robots, cutting robots, and welding robots. It is used with long-term bending and twisting of the equipment, providing the necessary guarantee for the safe and efficient operation of industrial robot equipment. Existing drag chain cables for robots are all devoted to increasing the softness of the wire itself, which enlarges the torsion angle of the cable, but makes the c...
