Description

Technical Field

[0001] Embodiments of this disclosure relate to the field of cable technology, and more specifically, to a high-rotation-resistant robot cable. Background Technology

[0002] With the progress of industrialization and the advent of the information age, electric robots are appearing more and more frequently in our lives and production. Electric robots have mechanical structures similar to human walking, waist turning, upper arm, forearm, wrist, and gripper, and they are playing an increasingly important role in our lives and production. For example, electric robots are used in the industrial production process of many modern factories. Many high-intensity or tedious tasks are completed by electric robots, such as spot welding, arc welding, assembly, painting, cutting, and handling. Some of these tasks require electric robots to have a large range of motion.

[0003] However, in industrial production, electric robots often work continuously for long periods of time, which causes the robot's cable to move continuously and bend considerably. In such cases, using ordinary cables would easily lead to severe wear and tear, and the internal protective layer of ordinary cables is easily damaged by compression, resulting in dangerous situations such as leakage. This phenomenon also limits the performance of electric robots in many specific situations and is not conducive to the development of electric robots.

[0004] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a high-rotation-resistant robot cable, which solves the technical problems in the related art where ordinary cables are easily subjected to high wear and tear, and ordinary cables are prone to damage to the internal protective layer due to compression, thereby causing dangerous situations such as leakage.

[0006] According to one aspect, at least one embodiment of this disclosure provides a high-rotation-resistant robot cable, comprising:

[0007] A plurality of wire cores and an outer sheath, wherein the outer sheath is disposed outside the wire cores;

[0008] A compression-resistant assembly is disposed between the conductor and the outer sheath;

[0009] An outer protective assembly, wherein the outer protective assembly is disposed outside the outer sheath;

[0010] The pressure-resistant component includes a flexible inner frame, which is supported between several of the wire cores. Each wire core is wrapped with a heat insulation layer, and a buffer sleeve is fitted around the heat insulation layer.

[0011] As a further technical solution, the buffer sleeve is wrapped with a shielding tape layer, and a shielding braided layer is wrapped between the shielding tape layer and the outer sheath. The insulation layer is filled with a pair of shock-absorbing pads.

[0012] As a further technical solution, the outer protective component includes a protective sleeve, which is fitted over the outer sheath. A pair of clamping tabs are fitted at both ends of the protective sleeve, and both ends of the clamping tabs are bent upwards.

[0013] As a further technical solution, tension sleeves are fitted to both ends of the clamping plate, and the tension sleeves are fitted tightly at the bending point of the clamping plate. The tension sleeves are made of rubber with strong resilience.

[0014] As a further technical solution, the surface of the protective sleeve is bent downwards from both ends toward the center.

[0015] As a further technical solution, the inner surface of the protective sleeve is provided with a groove, and the groove has a wavy structure.

[0016] As a further technical solution, the central part of the flexible inner frame is a hollow structure, and the flexible inner frame separates several of the wire cores.

[0017] As a further technical solution, the cross-section of the buffer sleeve is a ring structure composed of several circular strips spliced ​​together.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, a pressure-resistant component is provided. Through the interaction of structures such as a flexible inner frame, a heat insulation layer, a buffer sleeve, a shielding strip layer, a shielding braided layer, and a shock-absorbing pad, the internal multi-level coordination has the effect of resisting bending, squeezing, and deformation, thereby improving the pressure resistance performance and thus improving the performance and service life of the robot cable.

[0020] 2. In this disclosure, an external protective component is provided. Through the interaction of structures such as the protective sleeve, clamping plate, and pull-in sleeve, an additional layer of protection can be added to the bent part, improving the bending resistance and protecting the cable.

[0026] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0027] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0028] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0029] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-3 As shown, a high-rotation-resistant robot cable according to an embodiment of this disclosure is provided, comprising:

[0033] Several wire cores 1 and an outer sheath 2, the outer sheath 2 being disposed outside the wire cores 1;

[0034] Compression-resistant component 3 is disposed between the core 1 and the outer sheath 2;

[0035] Outer protective component 4 is disposed outside the outer sheath 2;

[0036] The pressure-resistant component 3 includes a flexible inner frame 3-1, which is supported between several wire cores 1. The wire cores 1 are wrapped with a heat insulation layer 3-2. The heat insulation layer 3-2 is fitted with a buffer sleeve 3-3. The buffer sleeve 3-3 is wrapped with a shielding strip layer 3-4. The shielding strip layer 3-4 and the outer sheath 2 are wrapped with a shielding braided layer 3-5. The heat insulation layer 3-2 is filled with a pair of shock-absorbing pads 3-6.

[0037] In some examples, to achieve the effect of resistance to bending and rotation, a pressure-resistant component 3 is designed. A flexible inner frame 3-1 is set at the innermost part to support the core 1 and provide a support effect. Outwardly, a heat insulation layer 3-2, a shielding strip layer 3-4, and a shielding braided layer 3-5 are arranged in sequence for heat insulation and shielding. A buffer sleeve 3-3 is set between the heat insulation and shielding strip layer 3-4 to enhance the effect of resistance to bending. Two shock-absorbing pads 3-6 are also filled inside to further reduce the compression of the core 1.

[0038] like Figures 1-3 As shown, this embodiment proposes an outer protective component 4 including a protective sleeve 4-1, which is fitted over the outer sheath 2. A pair of clamping plates 4-2 are fitted at both ends of the protective sleeve 4-1. Both ends of the clamping plates 4-2 are bent upwards. A tensioning sleeve 4-3 is fitted at both ends of the clamping plates 4-2. The tensioning sleeve 4-3 is fitted tightly at the bent part of the clamping plates 4-2. The tensioning sleeve 4-3 is made of a rubber material with strong resilience.

[0039] In some examples, in order to achieve the effect of protecting the main bending part of the cable, an outer protective component 4 is designed. A protective sleeve 4-1 is fitted on the outside of the cable. The center of the protective sleeve 4-1 is located at the main bending position. Two clamping pieces 4-2 are fitted on both ends of the protective sleeve 4-1. The two ends of the clamping pieces 4-2 are bent upward. Tensioning sleeves 4-3 are fitted on both ends of the two clamping pieces 4-2. They are made of rubber and are telescopic. By contracting and tightening the two clamping pieces 4-2, the protective sleeve 4-1 is fixed.

[0040] For example, such as Figure 1 As shown, the surface of the protective sleeve 4-1 curves downward from both ends toward the center.

[0041] In some examples, by tilting towards the center, the concave portion of the center of the protective sleeve 4-1 becomes the main bending portion, which protects the cable while bending.

[0042] For example, such as Figure 3 As shown, the inner surface of the protective sleeve 4-1 has a groove 5, which has a wavy structure.

[0043] In some examples, the wavy grooves 5 enhance the bending ability of the protective sleeve 4-1, increasing its service life.

[0044] For example, such as Figure 2 As shown, the central part of the flexible inner frame 3-1 is a hollow structure, and the flexible inner frame 3-1 separates several wire cores 1.

[0045] In some examples, a hollow structure is used to allow the central part to dissipate heat and reduce the temperature of the cable.

[0046] For example, such as Figure 2 As shown, the cross-section of the buffer sleeve 3-3 is a ring structure composed of several circular strips spliced ​​together.

[0047] In some examples, the ring structure composed of multiple circular strips allows the buffer sleeve 3-3 to separate the insulation layer 3-2 and the shielding strip layer 3-4 by a certain distance, thus achieving a buffering effect.

[0048] When needed, first slip the protective sleeve 4-1 onto the outside of the cable, then slip the clamping plates 4-2 onto both ends of the protective sleeve 4-1, and tighten the clamping plates 4-2 with the tensioning sleeve 4-3 to securely fix the protective sleeve 4-1 onto the cable. After connecting the cable, place the protective sleeve 4-1 at the main bending part.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
