Description

Technical Field

[0001] The utility model relates to the technical field of electric wires and cables, and more particularly to a highly flexible and bend-resistant robot cable. Background Art

[0002] A cable is a device for transmitting electrical energy or signals. It is usually composed of several or several groups of wires and has the characteristics of internal current conduction and external insulation. Cables can be used to transmit electrical (magnetic) energy and information, and realize electromagnetic energy conversion.

[0003] At present, cables are widely used. Cables are needed for connection and control in some industrial robots. Since robots are often used in industrial production, robots will produce a certain range of movements when in use. Cables are prone to bending when following the robot's operation. Therefore, cables will crack and be damaged after long-term use. Most existing robot cables generally increase flexibility through internal fillers to improve the bending resistance. However, the bending resistance of the outer protective layer is still poor, resulting in a short service life of the robot cable. For this reason, the utility model proposes a highly flexible and bending-resistant robot cable. Utility Model Content

A filler 5 is filled between the outer surface of the plurality of conductors 4 and the inner surface of the wrapping layer 3. The outer surface of the corrugated memory rubber sheath 2 is provided with a plurality of elastic snap rings 6, and the plurality of elastic snap rings 6 correspond to the wrapping layer 3.

[0027] Each wire 4 includes a metal shielding layer 41, an insulating shielding layer 42, an insulating layer 43, a conductor shielding layer 44 and a group of cores 45. The metal shielding layer 41 is located inside the wrapping layer 3, and the filler 5 is filled between the outer surface of the metal shielding layer 41 and the inner surface of the wrapping layer 3. The insulating shielding layer 42, the insulating layer 43, the conductor shielding layer 44 and a group of cores 45 are all located inside the metal shielding layer 41, and the metal shielding layer 41, the insulating shielding layer 42, the insulating layer 43, the conductor shielding layer 44 and a group of cores 45 are wrapped in sequence from the outside to the inside.

[0028] In this embodiment, the multiple wires 4 in the sheath 3 are the main transmission parts of the robot's electrical energy, realizing the power conduction and control of the robot. Each wire 4 is mainly composed of a metal shielding layer 41, an insulating shielding layer 42, an insulating layer 43, a conductor shielding layer 44 and a group of cores 45. A group of cores 45 is used to conduct current. The metal shielding layer 41, the insulating shielding layer 42 and the conductor shielding layer 44 are used to isolate the electromagnetic field in the cable from the external electromagnetic field. The insulating layer 43 acts as a component to isolate the conductor from the external electrical connection, ensuring that the current is transmitted along the core 45 without flowing to the outside world. The outer sheath 3 The structure of the part is the outer protective layer, which is mainly composed of an outer sheath 1 and a corrugated memory rubber sheath 2. The outer sheath 1 can prevent external mechanical damage, chemical corrosion and environmental influences. The corrugated memory rubber sheath 2 is in the shape of a corrugated tube and is tightly attached to the surface of the sheath 3 through multiple elastic clamps 6. It can absorb the force generated when the robot cable is bent. After the cable is bent and subjected to force, the corrugated memory rubber sheath 2 is compressed or stretched, which increases the flexibility of the outer protective layer, protects the multiple wires 4 inside, reduces the impact of bending on the cable as a whole, and can make the cable rebound quickly to avoid continuous bending and stretching of the cable.

[0029] Specifically, an inner steel wire rope reinforcement core 7 is provided in the wrapping layer 3 , and the inner steel wire rope reinforcement core 7 is located between the plurality of conductors 4 .

[0030] In this embodiment, the inner steel wire rope reinforcement core 7 is arranged at the center of the entire cable, which can further improve the overall strength of the robot cable and increase the tensile and bending resistance effects.

[0031] Specifically, a plurality of hemp ropes 8 are provided in the filler 5 , and the plurality of hemp ropes 8 correspond to the plurality of conducting wires 4 .

[0032] In this embodiment, multiple hemp ropes 8 are filled inside the wrapping layer 3 along with the filler 5, which can effectively improve the flexibility of the cable and make the robot cable more resistant to pulling and bending.

[0033] Specifically, an aramid fiber reinforcement layer 9 is provided between the outer surface of the corrugated memory rubber sheath 2 and the inner surface of the outer sheath 1 .

[0034] In this embodiment, the aramid fiber reinforcement layer 9 is arranged between the corrugated memory rubber sheath 2 and the outer sheath 1 by weaving, thereby improving the strength of the outer protection part formed by the corrugated memory rubber sheath 2 and the outer sheath 1, and further improving the tensile and bending resistance of the robot cable.

[0035] Specifically, a plurality of outer steel wire rope reinforcement cores 10 are fixedly connected between the inner and outer surfaces of the outer sheath 1 , and the plurality of outer steel wire rope reinforcement cores 10 are evenly distributed around the central axis of the outer sheath 1 .

[0036] In this embodiment, the plurality of outer steel wire rope reinforcement cores 10 improve the strength of the outer sheath 1 and can effectively prevent the outer sheath 1 from breaking.

[0037] Working principle: Multiple groups of wire cores 45 conduct current to achieve power conduction and control of the robot. When the robot cable is bent and subjected to stress, the corrugated memory rubber sheath 2 can absorb the force generated by the bending of the robot cable and cause compression or stretching, thereby improving the flexibility of the outer protective layer, protecting the multiple internal wires 4, reducing the impact of bending on the entire cable, and enabling the cable to rebound quickly to avoid continuous bending and stretching of the cable. The filler 5 inside the sheath 3, the inner steel wire rope reinforcement core 7 and multiple hemp ropes 8 further increase the flexibility of the robot cable, and improve the tensile and bending resistance of the robot cable.

[0038] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
