It will be apparent, however, to one of ordinary skill in the art that the embodiments may be practiced without limitation to these specific details. In some instances, well-known methods and structures have not been described in detail so as not to unnecessarily obscure the embodiments. In addition, all embodiments may be used in combination with each other.
As shown in fig. 1-3, the embodiment discloses a high-flexibility torsion-resistant robot cable, which comprises an outer protection layer and a cable core, wherein the outer protection layer is of an annular structure and is provided with an inner cavity 1 for installing the cable core. The outer protective layer sequentially comprises a sheath layer 2, an outer shielding layer 3 and an outer wrapping layer 4 from outside to inside. The cable core comprises at least one pair of data transmission units, namely a first data transmission unit 6 and a second data transmission unit 7; and at least four sets of power transmission units, which are a first power transmission unit 8, a second power transmission unit 9, a third power transmission unit 10, and a fourth power transmission unit 11, respectively; and a first filling cotton thread 5. The first filling cotton wire 5 is arranged at the center of the inner cavity 1, the data transmission units and the power transmission units are distributed on the periphery of the first filling cotton wire 5 in a spiral winding mode in the same direction, the first data transmission unit 6 and the second data transmission unit 7 are arranged oppositely, the center of the first filling cotton wire 5 is symmetrical, and the first power transmission unit 8, the second power transmission unit 9, the third power transmission unit 10 and the fourth power transmission unit 11 are respectively arranged on two sides of the first data transmission unit 6 and the second data transmission unit 7. In addition, the data transmission unit and the power transmission unit both adopt a back-twist process when the outer circumference of the first filling cotton 5 is twisted and wound. The data transmission unit and the power transmission unit have the same outer diameter.
In this embodiment, the first filling cotton wire 5 is arranged in the center of the cable core, and the data transmission unit and the power transmission unit are spirally wound around the periphery of the first filling cotton wire 5 in the same direction, so that the roundness of the cable is ensured, the flexibility of the cable core can be increased, the mechanical stress applied to the cable is partially borne, and the damage to the data transmission unit and the power transmission unit during bending and torsion of the cable is reduced. In addition, in this embodiment, the data transmission units and the power transmission units are distributed in a dispersed and symmetrical manner, and the outer diameters of the data transmission units and the power transmission units are the same, so that the overall stress uniformity of the cable core can be ensured, and the situation that the individual data transmission units or the power transmission units are broken due to uneven stress is avoided.
Specifically, in this embodiment, the sheath layer 2 is made of a thermoplastic elastomer material, which may be specifically implemented as thermoplastic polyurethane elastomer rubber (TPU material), where the TPU material has relatively strong elasticity and wear resistance, and is capable of bearing bending, stretching and twisting movements of the cable with high strength, so as to avoid occurrence of snake skin cracking of the sheath layer 2. In addition, the TPU material has higher mechanical strength, particularly has outstanding bearing capacity, impact resistance and shock absorption performance, can replace a cable core to eliminate partial external stress, and enhances the flexibility and torsion and turning resistance of the cable.
Specifically, in the present embodiment, the outer shielding layer 3 is formed by braiding a plurality of strands of tinned copper wires, and the outer shielding layer 3 can provide a shielding function, and can further enhance the tensile strength of the cable and eliminate the influence of external stress on the cable.
Specifically, in the present embodiment, the outer tape layer 4 has a two-layer structure including a first tape layer and a second tape layer. The first wrapping band layer is made of PTEF (polytetrafluoroethylene) material, specifically is in a film shape, and covers the outer side of the cable core in a longitudinal wrapping mode. The PTFE material has extremely low friction coefficient, and can play a role in lubrication when the cable is twisted, so that the damage of torsional stress to the cable core is reduced. In addition, the second wrapping layer is made of PET (polyethylene terephthalate plastic) material, specifically is in a film shape, and is covered on the outer side of the first wrapping layer in a wrapping mode, and the edge overlapping rate is more than 25%. The second tape layer adopts the winding mode to enable the structure of the cable core to form a whole and form a bundle, so that the influence on the service performance of the cable due to loose cable core structure in the twisting or bending process of the cable is avoided.
Specifically, in this embodiment, the structure of the data transmission unit takes the first data transmission unit 6 as an example, and the data transmission unit includes two insulating core wires, where the insulating core wires are composed of a plurality of conductors and a first insulating layer 12 wrapped outside the conductors, the conductors are specifically made of bare copper wires, and the first insulating layer 12 is specifically made of TPE (thermoplastic elastomer) material. The two insulating core wires are twisted into a double stranded wire pair, and a back-twisting process is adopted, so that the first data transmission unit 6 is guaranteed to have good flexibility. Second filling cotton threads are arranged on two sides of the core wire, so that the roundness and the tensile strength of the first transmission unit are guaranteed. The insulation core wire and the second filling cotton wire are covered with the inner wrapping tape layer, the inner wrapping tape layer is made of PET (polyethylene terephthalate plastic) material, and is particularly in a film shape, and is arranged in a longitudinal wrapping mode, so that the insulation core wire can be protected, the stability of the inner structure of the first transmission cable can be ensured, and the loose condition of the first transmission cable is avoided. An inner shielding layer 13 is arranged outside the inner wrapping band, and the inner shielding layer 13 covers the outer side of the inner wrapping band. The inner shielding layer 13 is formed by braiding a plurality of strands of tinned copper wires, and besides the shielding function, the inner shielding layer 13 can further enhance the tensile strength of the first data transmission unit 6 and eliminate the influence of external stress on the first data transmission unit 6. A second insulating layer 14 is provided outside the inner shielding layer 13, the second insulating layer 14 likewise being made of TPE (thermoplastic elastomer) material.
Specifically, in this embodiment, the mechanism of the power transmission unit takes the first power transmission unit 8 as an example, and includes a plurality of conductors and a third insulating layer 15 wrapped on the outer sides of the conductors, where the conductors are specifically made of bare copper wires, and the third insulating layer 15 is specifically made of TPE (thermoplastic elastomer) material. Wherein, the first insulating layer 12, the second insulating layer 14 and the third insulating layer 15 all adopt thin-wall insulating technology, which can reduce the outer diameter of the cable and is beneficial to saving the wiring space inside the equipment.
In addition, according to fig. 1, the embodiment also discloses a manufacturing method of the high-flexibility torsion-resistant robot cable, which specifically comprises the following steps:
Preparing a data transmission unit: extruding a first insulating layer 12 outside a plurality of bundled conductors to form two insulating core wires, and twisting the two insulating core wires into a double stranded wire by pairs, wherein a back-twisting process is adopted; an inner wrapping belt layer is longitudinally wrapped on the outer side of the insulating core wire, an inner shielding layer 13 is woven on the outer side of the inner wrapping belt layer, and a second insulating layer 14 is extruded on the outer side of the inner shielding layer 13. Wherein, the gap between the insulating core wire and the inner wrapping belt layer is filled with a second filling cotton thread.
