Description

Technical Field

[0001] This utility model relates to the technical field of cables, and in particular to a composite cable for automated equipment. Background Technology

[0002] With the rapid development of industrial automation technology, composite cables, as a key carrier for power transmission, control signal interaction, and data communication, are widely used in high-dynamic scenarios such as robotic arms, AGV transport vehicles, and reel equipment. These devices often require cables to withstand complex mechanical stresses such as multi-axis bending, high-frequency tensile stress, and torsion within a limited space, while ensuring the stability of high-current power supply and high-speed signal transmission.

[0003] However, existing composite cables have poor tensile strength, the conductors are prone to breakage and the insulation layer is prone to deformation, and the torsional strength of composite cables is insufficient, making the internal structure of the cable easily damaged under rotating conditions. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a composite cable for automated equipment, which can improve the tensile and torsional strength of the cable, making it widely applicable in automated industrial equipment and extending the cable's service life.

[0028] The following description, in conjunction with the accompanying drawings, describes an automated equipment composite cable according to an embodiment of the present invention.

[0029] Reference Figure 1 The present invention aims to provide an embodiment of a composite cable for automated equipment.

[0030] An embodiment of the present invention provides an automated equipment composite cable, comprising a center line 100, a wire assembly, and a braided layer 160. The center line 100 forms the center of the composite cable and includes a steel wire rope 110 and a first insulation layer 120 disposed on the outer surface of the steel wire rope 110. It includes power lines 130, network lines 140, and bus lines 150, which are distributed along the outer periphery of the center line 100 and are twisted together with the center line 100 as the center. The braided layer 160 is made of aramid fiber and is used to braid and wrap the wire assembly.

[0031] It is understood that this embodiment uses a power line 130, a network cable 140, and a bus 150. The power line 130 is used to transmit electrical energy, the network cable 140 supports Gigabit Ethernet and can transmit data at high speed, and the bus 150 connects devices such as PLCs, sensors, and controllers, supporting real-time control signal transmission. Furthermore, the power line 130, network cable 140, and bus 150 are twisted together with the center line 100 as the center, so that the power line 130, network cable 140, and bus 150 form a composite cable, reducing wiring complexity and improving the integration of the automation system.

[0032] This embodiment features a centerline 100 and a braided layer 160. The centerline 100, through a steel wire rope 110, provides the composite cable with axial tensile strength. The high-strength metal material significantly enhances the cable's mechanical strength, enabling it to withstand the tension generated by frequent traction, suspension, or high-speed movement. This prevents conductor breakage or insulation deformation caused by repeated stretching. Furthermore, the braided layer 160, made of aramid fiber, forms a radial anti-torsion mesh, further optimizing torsional resistance and preventing damage to the cable's internal structure under rotational conditions. This improves the cable's tensile and torsional resistance, making it widely applicable in automated industrial equipment and extending cable lifespan.

[0033] In some embodiments of this utility model, the power line 130 includes a plurality of first wire cores 170 and a first PVC strip 180, wherein the plurality of first wire cores 170 are twisted together with the first PVC strip 180 as the center.

[0034] It is understandable that the first wire core 170 and the first PVC strip 180 are twisted together, and the first PVC strip 180 is distributed among multiple first wire cores 170 to reduce wear caused by friction between the first wire cores 170.

[0035] In some embodiments of this utility model, the power line 130 also has a second insulation layer 190, the material of which is HDPE.

[0036] Understandably, the power line 130 uses HDPE as the second insulation layer 190. HDPE, or high-density polyethylene, has a high resilience under tension, which significantly reduces the risk of permanent thinning of the insulation layer.

[0037] In some embodiments of this utility model, the bus 150 includes a second wire core 200 and a second PVC strip 210, which are twisted together.

[0038] It is understandable that there can be two second cores 200. The second cores 200 and the second PVC strip 210 are twisted together. The second PVC strip 210 can fill the gap between the second cores 200 and reduce the wear caused by friction between the second cores 200.

[0039] In some embodiments of this utility model, the bus 150 further includes an aluminum foil strip 220, which wraps the twisted second wire core 200 and the second PVC strip 210.

[0040] Understandably, the aluminum foil strip 220 has a 25% overlap rate, and the aluminum foil strip 220 forms a full wrap around the second wire core 200 to suppress external electromagnetic interference and ensure the stability of data signal transmission.

[0041] In some embodiments of this utility model, the bus 150 further includes a shielding layer 230, which is disposed on the outer surface of the aluminum foil strip 220.

[0042] Understandably, the combination of aluminum foil strip 220 and shielding layer 230 solves the problem of gap leakage in traditional single-layer shielding under high dynamic scenarios.

[0043] In some embodiments of this utility model, the bus 150 further includes a middle sheath 240, which is extruded on the outer surface of the shielding layer 230. The material of the middle sheath 240 is PUR, which is reactive polyurethane hot melt adhesive. The PUR middle sheath 240 has excellent resilience and is suitable for mobile scenarios such as robots and machine tools.

[0044] In some embodiments of this utility model, the material of the first insulating layer 120 is LLDPE, which is linear low-density polyethylene. It has high tensile strength and tear strength, making the first insulating layer 120 less prone to damage.

[0045] In some embodiments of this utility model, a wrapping layer 250 is also included. The wrapping layer 250 is located inside the braided layer 160. The wrapping layer 250 wraps the twisted power lines 130, network cables 140 and bus 150. The material of the wrapping layer 250 is a thin non-woven fabric.

[0046] Understandably, the thin nonwoven fabric serves as a buffer between the wire assembly and the braided layer 160 to prevent the power lines 130, network cables 140, and bus 150 from becoming loose after being twisted together.

[0047] In some embodiments of this utility model, an outer sheath 260 is also included. The outer sheath 260 is extruded on the outer surface of the braided layer 160, and the material of the outer sheath 260 is TPU.

[0048] Understandably, TPU stands for thermoplastic polyurethane. The TPU outer sheath 260 has properties such as oil resistance, tear resistance, and resistance to high and low temperatures (-40℃~105℃), which makes the composite cable suitable for harsh industrial environments.

[0049] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
