Description

Technical Field

[0001] This utility model relates to the field of cable technology for vision equipment, and in particular to a cable for robot vision equipment that is resistant to horizontal torsion. Background Technology

[0002] Vision equipment cables are key components connecting vision acquisition devices (such as cameras and sensors) to processing terminals and power supplies, playing a crucial role in transmitting image signals, data, and power. Their performance directly affects the operational stability and signal transmission quality of vision equipment, and they are widely used in various fields such as industrial inspection, security monitoring, and robot vision.

[0003] Because robots often need to perform multi-dimensional and multi-angle movements during operation, especially horizontal rotation, the cables connected to the vision devices used in robots must have excellent horizontal rotation resistance. If the cable's horizontal rotation resistance is insufficient, it will be subjected to torsional stress continuously during robot operation, which can easily lead to problems such as internal conductor breakage and insulation layer cracking over time.

[0004] Existing cables have many defects and cannot meet the needs of robot vision equipment. Structurally, many cables use single-strand or thick copper wire as conductors, which have poor flexibility and cause significant stress concentration during horizontal rotation, making them prone to breakage. Moreover, the shielding layer mostly uses rigid structures such as aluminum foil wrapping, which are easily damaged during torsion, affecting the shielding effect. Furthermore, the insulation layer and sheath layer are mostly made of a single material without special structural design, resulting in high interlayer friction and insufficient deformation space, making them prone to cracking under repeated torsion. Therefore, a horizontal torsion resistant cable for robot vision equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cable for robot vision equipment that is resistant to horizontal torsion, aiming to solve the problem mentioned in the prior art that "the cable of robot vision equipment has poor flexibility and large interlayer friction".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable for a robot vision device that is resistant to horizontal torsion, comprising a conductor wire, a twisted wire fixedly connected to the outer wall of the conductor wire, a Kevlar fiber fixedly connected to the outer wall of the twisted wire, an insulating sleeve fixedly connected to the outer wall of the Kevlar fiber, a shielding sleeve fixedly connected to the outer wall of the insulating sleeve, a protective sleeve fixedly connected to the outer wall of the shielding sleeve, and reinforcing components provided on the surfaces of the insulating sleeve and the protective sleeve;

[0007] The reinforcing component includes spiral ridges, which are fixedly connected to the outer wall of the protective sleeve. The inner wall of the protective sleeve has a first spiral groove, and the outer wall of the insulating sleeve has a second spiral groove.

[0008] As a further description of the above technical solution:

[0009] The twisted wire is provided in at least three sets, and the twisted wire is spirally wrapped around the outer wall of the conductor wire with the conductor wire as the central axis.

[0010] As a further description of the above technical solution:

[0011] The Kevlar fibers are provided in at least three groups, and the Kevlar fibers are arranged in a spiral and twisted manner with the conductor wire as the central axis.

[0012] As a further description of the above technical solution:

[0013] The first spiral groove and the second spiral groove are spiral-shaped groove structures, and the spiral angle of the first spiral groove and the second spiral groove is 25° to 30°.

[0014] As a further description of the above technical solution:

[0015] The spiral embossing is a spiral-shaped convex structure, and the spiral angle of the spiral embossing is 20° to 28°.

[0016] As a further description of the above technical solution:

[0017] The diameter of the conductor wire and the twisted wire is 0.08 mm to 0.1 mm.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the core skeleton of the cable is constructed by the precise twisting of multiple twisted wires and the strong reinforcement of Kevlar fiber, which greatly improves its torsional performance. The shielding sleeve made of high density braid can effectively intercept external electromagnetic signals and prevent interference from penetrating the shielding layer and affecting the stable transmission of internal signals. The dual protection system of insulating sleeve and protective sleeve further strengthens the overall structural strength of the cable. The two sets of spiral grooves can effectively reduce the frictional resistance between cable layers, so that the torsional resistance of the cable is upgraded in all aspects.

[0020] 2. In this utility model, the spiral embossed design makes the thickness of the protective sleeve uneven. When the cable is subjected to torsional force, the stress will preferentially act on the "weak link" on the surface of the protective sleeve, thereby converting part of the energy generated by the torsion into the deformation potential energy of the outer layer material. This can prevent the torsional force from acting directly on the inner layer structure, thus protecting the internal structure of the cable. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a cable for a robot vision device that is resistant to horizontal torsion. The cable includes a conductor wire 1, with a twisted wire 2 fixedly connected to the outer wall of the conductor wire 1. The diameters of the conductor wire 1 and the twisted wire 2 are 0.08mm to 0.1mm. The finer copper wire provides higher flexibility, allowing the cable to distribute stress during torsion and reducing the risk of breakage. Kevlar fiber 3 is fixedly connected to the outer wall of the twisted wire 2, and an insulating sleeve 4 is fixedly connected to the outer wall of the Kevlar fiber 3. The insulating sleeve 4 can be made of soft TPU material and can provide… To buffer stress, a shielding sleeve 5 is fixedly connected to the outer wall of the insulating sleeve 4. The shielding sleeve 5 is made of 8 strands by 48 fine copper wires woven in a cross-weaving manner to form a mesh. The high weaving density of the shielding sleeve 5 forms a closed structure similar to a "metal mesh cover", which can effectively reflect and absorb external electromagnetic signals and prevent them from penetrating the shielding layer and interfering with the internal signal transmission. A protective sleeve 6 is fixedly connected to the outer wall of the shielding sleeve 5. The protective sleeve 6 can be made of wear-resistant TPEE material, which can effectively protect the cable. Reinforcing components 7 are provided on the surfaces of the insulating sleeve 4 and the protective sleeve 6.

[0029] Reference Figure 2 - Figure 4The reinforcing component 7 includes a spiral groove 71, which is fixedly connected to the outer wall of the protective sleeve 6. The inner wall of the protective sleeve 6 is provided with a first spiral groove 72, and the outer wall of the insulating sleeve 4 is provided with a second spiral groove 73. The first spiral groove 72 and the second spiral groove 73 can reduce the problems of scratches and tears in the protective sleeve layer caused by instantaneous strong friction.

[0030] Reference Figure 1 - Figure 3 At least three sets of twisted wire 2 are provided, and the twisted wire 2 is spirally wrapped around the outer wall of the conductor wire 1 with the conductor wire 1 as the central axis. At least three sets of Kevlar fiber 3 are provided, and the Kevlar fiber 3 is spirally arranged with the conductor wire 1 as the central axis and interspersed with the twisted wire 2. The Kevlar fiber 3 can evenly distribute the stress to the entire length of the cable through its own high strength, avoiding conductor breakage or sheath tearing caused by local stress concentration.

[0031] Reference Figure 2 and Figure 3 The first spiral groove 72 and the second spiral groove 73 are spiral groove structures with a spiral angle of 25° to 30°. The spiral convex strip 71 is a spiral convex strip structure with a spiral angle of 20° to 28°.

[0032] Working principle: At least three sets of twisted wires 2 are wrapped around the outer wall of conductor wire 1 in a twisted form, and the diameter of twisted wires 2 and conductor wire 1 is controlled between 0.08mm and 0.1mm. The thinner copper wire can provide the cable with higher flexibility, so that the cable can distribute stress during twisting and reduce the risk of breakage. The Kevlar fiber 3 inserted between the twisted wires 2 can enhance the overall tensile strength of the cable. During horizontal twisting, it can act as a "skeleton" to bear the axial and radial tension of the cable. When the cable is twisted, the internal conductor and shielding layer will generate tensile or compressive stress. Kevlar fiber 3 can evenly distribute the stress to the entire length of the cable through its own high strength, avoiding conductor breakage or sheath tearing caused by local stress concentration, thereby improving the horizontal torsional resistance of the cable.

[0033] When the cable rubs during horizontal rotation, the first spiral groove 72 and the second spiral groove 73 can transform the original "straight hard friction" into "oblique sliding friction" along the spiral direction, which is equivalent to providing a buffer "guide channel" for the friction force. This design can reduce "stuttering" or "impact friction" during the friction process, and allow the friction energy to be gradually released along the spiral groove, reducing problems such as scratches and tears in the sheath layer caused by instantaneous strong friction, thereby further improving the cable's resistance to horizontal rotation.

[0034] The design of the spiral ridges 71 creates an uneven distribution of the outer material thickness, with thicker ridges and thinner grooves. When the cable is subjected to torsional force, the stress will preferentially act on the "weakest link" in the structure, namely the groove area between the spiral ridges 71. The spiral ridges 71 will tilt along the torsional direction, and the grooves between adjacent spiral ridges 71 will be compressed or stretched. This process will convert part of the energy generated by the torsion into the deformation potential energy of the outer material, thereby preventing the torsional force from acting directly on the inner structure and protecting the internal structure of the cable.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
