Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a wear-resistant and bend-resistant cable for robots. Background Technology

[0002] The "Industry 4.0" concept proposed by the Chinese government, known as the Fourth Industrial Revolution, has triggered a new round of industrial transformation competition globally. In the future, robots, industrial automation, and intelligentization will be increasingly prevalent in more and more fields. The "Robot Industry Development Plan" issued by the Ministry of Industry and Information Technology and other ministries believes that by 2020, the annual sales revenue of service robots in my country will exceed 30 billion yuan, and will continue to maintain a high growth trend with the progress of industrial automation. Robot cables are the "blood vessels" and "nerves" of robots and are important components of robots. Highly flexible, bend-resistant, torsion-resistant, and long-life robot-specific cables will inevitably become the preferred cables for leading domestic and foreign machinery and equipment manufacturers.

[0003] One type of robot cable currently available has poor wear and bending resistance, making it prone to breakage during use. This limitation makes it less practical. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of poor wear and bending resistance, easy breakage during use, large limitations, and poor practicality of existing technologies, and to propose a wear-resistant and bending-resistant cable for robots.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant and bend-resistant cable for robots, comprising a cable body, a battery core inside the cable body, an insulation layer on the outside of the battery core, a fireproof layer on the outside of the insulation layer, a plurality of memory rubber rods between the fireproof layer and the insulation layer, a waterproof layer attached to the outer wall of the fireproof layer, a memory rubber film attached to the outer wall of the waterproof layer, and a wear-resistant layer attached to the outer wall of the memory rubber film.

[0006] Preferably, the wear-resistant layer contains an anti-wear buffer layer, and a biomimetic epidermal layer is attached and fixed to the outer wall of the anti-wear buffer layer.

[0007] Preferably, the end of the wear-resistant buffer layer away from the biomimetic epidermal layer is bonded and fixed to the memory rubber film.

[0008] Preferably, a filler layer is provided between the battery cell and the insulating layer.

[0009] Preferably, a support layer is provided between the insulating layer and the fireproof layer, and the insulating layer and the fireproof layer are fixed together by the support layer.

[0010] Preferably, the memory rubber rod is installed within the support layer.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, the memory rubber rod absorbs external force through elastic deformation when the cable body is subjected to mechanical stresses such as bending and torsion, preventing the internal core and insulation layer from breaking or wearing due to excessive bending. In addition, the support function of the memory rubber rod can stabilize the internal structure of the cable body, prevent the conductor from loosening or the insulation layer from misaligning, and improve the overall mechanical performance reliability. The memory rubber film can dynamically absorb deformation energy through the extension and rebound of the film when the cable body is bent. The memory rubber film can quickly return to its original shape after deformation, inhibiting the "plastic deformation accumulation" caused by long-term repeated bending of the cable body, achieving a secondary bending and fracture resistance effect, which is more practical. In addition, the device uses a honeycomb silicone anti-wear buffer layer. The honeycomb structure has unique mechanical properties and can effectively absorb and disperse energy when the cable is subjected to external force compression, stretching, bending or impact. Just as a honeycomb can withstand external pressure and protect its internal structure, honeycomb silicone can evenly distribute the external force acting on the cable, reducing local stress concentration. This prevents important components such as the conductor core and insulation layer inside the cable from being damaged or deformed due to excessive force, thus protecting the electrical and mechanical properties of the cable. Through the setting of the biomimetic skin layer, the surface of the wear-resistant layer is processed with a micron-level ridge structure that forms a 45° angle with the direction of movement of the cable body. This reduces the cutting effect of solid particles, achieving a wear-resistant effect and making it more practical. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, as Figure 1-3 As shown, this utility model provides a wear-resistant and bend-resistant cable for robots, including a cable body 1, a battery core 2 inside the cable body 1, an insulation layer 4 on the outside of the battery core 2, a fireproof layer 7 on the outside of the insulation layer 4, a plurality of memory rubber rods 6 between the fireproof layer 7 and the insulation layer 4, a waterproof layer 8 attached to the outer wall of the fireproof layer 7, a memory rubber film 9 attached to the outer wall of the waterproof layer 8, and a wear-resistant layer 10 attached to the outer wall of the memory rubber film 9.

[0020] The overall effect of Embodiment 1 is that, through the setting of the memory rubber rod 6, when the cable body is subjected to mechanical stress such as bending and torsion, the memory rubber rod 6 can absorb external force through elastic deformation, preventing the internal core 2 and insulation layer 4 from breaking or wearing due to excessive bending. In addition, the supporting role of the memory rubber rod 6 can stabilize the internal structure of the cable body 1, prevent the conductor from loosening or the insulation layer 4 from misaligning, and improve the reliability of the overall mechanical performance. Through the setting of the memory rubber film 9, the deformation energy can be dynamically absorbed through the extension and rebound of the film when the cable body 1 is bent. The memory rubber film 9 can quickly return to its original shape after deformation, suppressing the "plastic deformation accumulation" caused by long-term repeated bending of the cable body 1, achieving the effect of secondary bending and fracture resistance, and making it more practical. In addition, through the setting of the anti-wear buffer layer 11, which uses honeycomb silicone, the honeycomb structure has unique mechanical properties and can effectively absorb and disperse energy when the cable is subjected to external force compression, stretching, bending or impact. Just as a honeycomb can withstand external pressure and protect the structure inside the honeycomb, honeycomb silicone can evenly distribute the external force acting on the cable, reduce local stress concentration, and thus prevent important components such as the conductor core and insulation layer inside the cable from being damaged or deformed due to excessive force, thereby protecting the electrical and mechanical properties of the cable.

[0021] Example 2, as Figure 1-3As shown, the wear-resistant layer 10 has an anti-wear buffer layer 11 inside, and a bionic skin layer 12 is attached and fixed to the outer wall of the anti-wear buffer layer 11. The end of the anti-wear buffer layer 11 away from the bionic skin layer 12 is attached and fixed to the memory rubber film 9. A filling layer 3 is provided between the battery cell 2 and the insulation layer 4. A support layer 5 is provided between the insulation layer 4 and the fireproof layer 7. The insulation layer 4 and the fireproof layer 7 are fixed together by the support layer 5. The memory rubber rod 6 is installed in the support layer 5.

[0022] The overall effect of Embodiment 2 is as follows: by setting the biomimetic skin layer 12, the micron-level ridge structure processed on the surface of the wear-resistant layer 10 forms a 45° angle with the direction of movement of the cable body 1, which can reduce the cutting effect of solid particles and achieve wear resistance, making it more practical. By setting the fireproof layer 7, and the fireproof layer 7 using magnesium oxide, which is an inorganic oxide and does not contain organic components, it does not produce smoke, toxic gases or corrosive substances when burning, meeting the modern fire safety requirements of "low smoke and halogen-free", and is especially suitable for densely populated places or precision equipment environments, making it more practical. By setting the waterproof layer 8, the cable body 1 has a waterproof effect.

[0023] Working principle: When this device is in use, the memory rubber rod 6 absorbs external force through elastic deformation when the cable body is subjected to mechanical stress such as bending or torsion, preventing the internal core 2 and insulation layer 4 from breaking or wearing due to excessive bending. In addition, the supporting effect of the memory rubber rod 6 can stabilize the internal structure of the cable body 1, prevent the conductor from loosening or the insulation layer 4 from misaligning, and improve the overall mechanical performance reliability. Through the setting of the memory rubber film 9, the deformation energy can be dynamically absorbed through the extension and rebound of the film when the cable body 1 is bent. The memory rubber film 9 can quickly return to its original shape after deformation, suppressing the "plastic deformation accumulation" caused by long-term repeated bending of the cable body 1, achieving the effect of secondary bending and fracture resistance, and making it more practical. In addition, the device is equipped with an anti-wear buffer layer 11, which uses honeycomb silicone. The honeycomb structure has unique mechanical properties and can effectively absorb and disperse energy when the cable is subjected to external force compression, stretching, bending or impact. Just as a honeycomb can withstand external pressure and protect its internal structure, honeycomb silicone can evenly distribute the external force acting on the cable, reducing local stress concentration. This prevents important components such as the conductor core and insulation layer 4 inside the cable from being damaged or deformed due to excessive force, thus protecting the electrical and mechanical properties of the cable. Through the setting of the biomimetic skin layer 12, the surface of the wear-resistant layer 10 is processed with a micron-level ridge structure at a 45° angle to the direction of movement of the cable body 1. This reduces the cutting effect of solid particles, achieving a wear-resistant effect and enhancing practicality. Through the setting of the fireproof layer 7, which uses magnesium oxide, an inorganic oxide that does not contain organic components, it does not produce smoke, toxic gases, or corrosive substances when burning, meeting the modern fire safety requirements of "low smoke and halogen-free". It is especially suitable for densely populated places or precision equipment environments, enhancing practicality. Through the setting of the waterproof layer 8, the cable body 1 is made waterproof.
