Cable for flexible robot and manufacturing method

Abstract

The invention discloses a cable for a flexible robot, which comprises: a conductor braided by polyparaphenylene terephthalamide fibers and a plurality of oxygen-free copper wires; respectively covering each conductor to form each wire core Each polyvinyl chloride insulating layer; the copper wire shielding layer covering all the wire cores; the PUR sheath covering the copper wire shielding layer. The invention also discloses a method for manufacturing a cable for a flexible robot, including: placing poly-p-phenylene terephthalamide fibers in the center, placing a plurality of oxygen-free copper wires on the outer layer, and then braiding through a braiding machine A conductor with a density greater than 90% is formed into a conductor; a layer of PVC insulation is extruded outside the conductor by insulation extrusion equipment to form a core; a braiding machine is used to tightly weave the multi-strand core with a layer of braid density greater than 85% The copper wire shielding layer; outside the copper wire shielding layer, a PUR sheath is extruded by a sheath extruder. The invention is suitable for flexible robots with high stretching and twisting frequencies and many friction times.

Problems solved by technology

In some occasions, the robot cable needs to be in an oppressed environment for a long time, and the sensing ability of a certain part of the cable will continue to decrease, which will cause the metal wire to be severely stretched, resulting in weakened cable transportation performance, and a better conductor structure is required. to improve its stretch

Although polyvinyl chloride is a composite plastic material with strong insulation performance and good insulation performance in use, the wear resistance of polyvinyl chloride as a sheath is not particularly good, so it is necessary to use high-efficiency composite materials to lift cables Resistance to friction force during use
