Description

Technical Field

[0001] This invention relates to the field of cable technology, and specifically to a flexible motion cable for intelligent vision robots. Background Technology

[0002] With the revolutionary changes brought about by innovative technologies such as artificial intelligence, big data, 5G, and intelligent sensing, the field of robotics, with artificial intelligence at its core, is increasingly highlighting the "random, multi-joint characteristics of humans." In the future, robots will be more intelligent and flexible, and sub-fields such as robot vision and speech recognition are beginning to take shape. Artificial intelligence is transforming from a highly imaginative business concept into a commercial track with enormous development prospects. Artificial intelligence is deeply integrated into the new round of technological revolution and industrial transformation, leading the direction of future business development.

[0003] Intelligent vision robots can control the relative position and orientation of the robot's end effector (robotic arm) relative to a target or target feature based on visual information. For example, an eight-axis intelligent vision welding robot is an eight-degree-of-freedom dedicated robot, with six axes belonging to the welding robot and the other two axes belonging to the welding positioner. The operating system enables coordinated movement between the welding robot and the positioner, using a motion control card to control the robot's spatial position and speed. The welding positioner, working in conjunction with the welding robot, expands the welding robot's workspace and improves welding production efficiency and quality. The aforementioned robot combines contact-type weld seam tracking with a camera-based weld seam tracking system. Before welding, data and images of the weld seam are acquired. Computer software processes the weld seam data and images to generate a virtual weld seam. The virtual weld seam recognition system controls the actuator to track the weld seam during welding, improving weld quality. Human infrared sensor switches are installed in the welding torch to ensure worker safety; and visual sensors are used as measuring tools to measure the position of the robot's end effector or target. Visual information is used to control the relative position and orientation of the robot's end effector relative to the target or target feature, thereby reducing grasping errors and mistakes.

[0004] Typically, the movements of intelligent vision robots are controlled by motors to achieve precise positioning. However, this approach results in slow movements and insufficient flexibility. To improve flexibility, a new robot drive method has been developed. The principle involves connecting the robot's robotic arm to an air compressor via a gas pipeline. By controlling the continuous inflation and deflation of the air compressor, the gas pipeline can be extended, contracted, and bent, thereby driving the robotic arm's precise movements and significantly improving flexibility.

[0005] However, currently, flexible cables for intelligent vision robots mainly exist as independent units, such as a single USB cable or a single HDMI cable, rather than a unified whole. Secondly, current flexible cables for intelligent vision robots lack the special function of free extension and precise positioning. In other words, conventional flexible cables can only passively follow the robot's movements. However, changes in the cable's position cause changes in the relative force between the cable and the robot, making it difficult to maintain stable synchronization between the cable's movements and the robot's movements, thus affecting the accuracy of the intelligent vision robot's motion. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention provides a flexible motion cable specifically for intelligent vision robots.

[0007] The technical solution adopted in this invention is: a flexible motion cable for intelligent vision robots, comprising a main cable core, a bus wrapping layer, a bus braided layer and a bus outer sheath arranged sequentially from the inside to the outside. The main cable core is circular in shape and includes an audio / video cable, a storage cable, three telescopic tubes, a silicone hose and a total filler material.

[0008] The telescopic tube includes a foamed insulator with multiple uniformly arranged hollow pipes formed on it. The foamed insulator is covered with a telescopic tube wrapping layer, and a steel wire braiding layer is provided outside the telescopic tube wrapping layer. A telescopic tube inner sheath layer is provided outside the steel wire braiding layer.

[0009] The audio / video cable includes, from the inside out, an audio / video cable core, an audio / video cable wrapping layer, an audio / video cable braided layer, and an audio / video cable sheath; the audio / video cable core is composed of a first differential signal line, a first audio transmission line, three first power lines, two first video control lines, and several first filler PE strips, and is circular in shape.

[0010] The storage cable includes, from the inside out, a storage cable core, a storage cable wrapping layer, a storage cable braiding layer, and a storage cable sheath; the storage cable core is composed of a second differential signal line, a second audio transmission line, two second power lines, two second video control lines, and several second filler PE strips, and is circular in shape.

[0011] The conductors of both the first differential signal line and the second differential signal line are made of silver-plated stranded copper wire.

[0012] Both the first and second audio transmission lines use single-mode optical fiber cores as conductors.

[0013] The bus wrapping layer, audio / video cable wrapping layer, and storage cable wrapping layer each consist of a two-layer structure: the first layer uses ePTFE wrapping, and the second layer uses aluminum foil Mylar wrapping.

[0014] The bus braided layer, audio / video cable braided layer, and storage cable braided layer are all braided using a mixture of tin-plated copper foil wire and tin-plated copper wire.

[0015] The outer sheath of the bus, the audio / video cable sheath, and the storage cable sheath are all made of TPU material.

[0016] The total filler material used is Kevlar 400D.

[0017] The beneficial effects of this invention are as follows: by adopting the above solution, the audio and video cable and the storage cable are formed into a unified whole structure. At the same time, three telescopic tubes and one silicone hose are set. The telescopic tubes and silicone hose can be used to connect to the air compressor branch pipe. By controlling the air compressor to continuously charge and release air, the cable can be made to actively move to meet the robot's action requirements, realize the robot's precise action, and achieve the requirement of completing fine grasping action.

[0027] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1-2As shown, a flexible motion cable for intelligent vision robots includes a main cable core, a bus wrapping layer 6, a bus braided layer 7, and a bus outer sheath 8 arranged sequentially from the inside to the outside. The main cable core is circular in shape and includes an audio / video cable 1, a storage cable 2, three telescopic tubes 3, a silicone hose 4, and a total filler material 5.

[0029] like Figure 3-5 As shown, the audio / video cable 1 includes, from the inside out, an audio / video cable core, an audio / video cable wrapping layer 16, an audio / video cable braided layer 17, and an audio / video cable sheath 18; the audio / video cable core is composed of a first differential signal line 11, a first audio transmission line 12, three first power lines 13, two first video control lines 14, and several first filler PE strips 15.

[0030] The first differential signal line 11 includes two first signal lines 111 and one first signal ground line 112. The first signal lines 111 use 28AWG (7 / 0.127) silver-plated stranded copper wire as conductors and FEP material as insulation. The two first signal lines 111 are twisted together, and the silver-plated stranded copper wire is used as the conductor of the first signal lines 111, so that it has extremely fast transmission speed and extremely high conductivity.

[0031] The first signal ground wire 112 directly uses 28AWG (7 / 0.127) silver-plated stranded copper wire without external insulation. The first signal wire 111 and the first signal ground wire 112 are jointly covered by a first PET wrapping layer 113, which uses 6mm wide and 0.035mm thick PET wrapping tape with a shielding rate of 135%. The first PET wrapping layer 113 is covered by a first AL / MY wrapping layer 114, which uses 7mm wide and 0.035mm thick aluminum foil Mylar wrapping tape with a shielding rate of 135%. The first AL / MY wrapping layer 114 is covered by a first heat-fused wrapping tape 115 with a shielding rate of 135%. The multi-wrap structure is stable. The aluminum foil Mylar wrapping tape has the function of single-sided conductivity and single-sided insulation, which makes the first differential signal wire 11 have a good shielding effect and a good high-fidelity signal transmission effect.

[0032] The first audio transmission line 12 includes four first audio optical fibers 121. The four first audio optical fibers 121 are respectively made of OM1.5, OM2 or OM2+, OM3 and OM4 single-mode optical fiber cores. Single-mode optical fiber transmission is used, and the signal is not affected by any external RFI / EMI interference. Two insulation structures are formed outside the optical fiber core, namely FEP material inner insulation and HDPE material outer insulation. The four first audio optical fibers 121 are twisted together and are covered by a first ePTFE wrapping layer 122. The ePTFE wrapping layer is 8mm wide and 0.005mm thick, with a shielding rate of 135%. The ePTFE wrapping layer has excellent waterproof, moisture-permeable and windproof properties. It is not corroded by any chemical reagents, does not absorb moisture, does not burn, and is extremely stable to oxygen and ultraviolet light, with excellent biological adaptability. A first intermediate layer 123 is formed outside the ePTFE wrapping layer 122. The first intermediate layer 123 is made of gas-phase compounded industrial-grade silicone rubber.

[0033] The first power line 13 uses 24AWG (19 / 0.12) tin-plated stranded copper wire as the conductor and TPEE material as insulation.

[0034] The first video control line 14 uses 26AWG (11 / 0.12) tin-plated stranded copper wire as the conductor and FEP material as the insulation.

[0035] The first filling PE strip 15 has 1-3 strips, which are filled according to the actual roundness to ensure that the audio and video cable core is round as a whole.

[0036] The audio / video cable sheathing layer 16 includes an audio / video cable PET sheathing layer and an audio / video cable AL / MY sheathing layer. The audio / video cable PET sheathing layer 16 uses PET sheathing with a width of 10mm and a thickness of 0.035mm and covers the audio / video cable core, with a sheathing rate of 135%. The audio / video cable AL / MY sheathing layer uses aluminum foil Mylar sheathing with a width of 12mm and a thickness of 0.035mm and covers the audio / video cable PET sheathing layer, with a sheathing rate of 135%. The aluminum foil Mylar sheathing has the function of being conductive on one side and insulating on the other side, which makes the audio / video cable 1 have a good shielding effect and a good high-fidelity signal transmission effect.

[0037] The audio / video cable braided layer 17 is made of 8 spindles of 30AWG tin-plated copper foil wire and 8 spindles of tin-plated copper wire. The combined braiding greatly improves the softness and bending performance of the braid, while effectively isolating interference from external electromagnetic waves, robot equipment radiation sources and radio waves.

[0038] The audio / video cable sheath 18 is made of TPU material. TPU sheaths possess excellent high tensile strength and tear resistance, high toughness, and excellent bending resistance. They are also wear-resistant, cold-resistant, oil-resistant, water-resistant, aging-resistant, weather-resistant, and mildew-resistant. Furthermore, they offer windproof and cold-proof protection, warmth retention, UV protection, and energy release capabilities. Additionally, they have high mechanical strength, strong load-bearing capacity, and good impact resistance and shock absorption.

[0039] The aforementioned audio / video cable 1 is mainly used to transmit high-definition signals during the operation of intelligent vision robots. It can also convert high-definition signals into audio and video effects, achieve accurate recognition and action, and support higher resolution video such as 8K and better audio effects.

[0040] like Figure 6-8 As shown, the storage line 2 includes, from the inside out, a storage cable core, a storage cable wrapping layer 26, a storage cable braided layer 27, and a storage cable sheath 28; the storage cable core is composed of a second differential signal line 21, a second audio transmission line 22, two second power lines 23, two second video control lines 24, and several second filler PE strips 25.

[0041] The second differential signal line 21 includes two second signal lines 211 and one second signal ground line 212. The second signal lines 211 use 28AWG (7 / 0.127) silver-plated stranded copper wire as conductors and FEP material as insulation. The two second signal lines 211 are twisted together. The use of silver-plated stranded copper wire as conductors gives the second signal lines 211 extremely fast transmission speed and extremely high conductivity.

[0042] The second signal ground wire 212 directly uses 28AWG (7 / 0.127) silver-plated stranded copper wire without external insulation. The second signal wire 211 and the second signal ground wire 212 are jointly covered by a second PET wrapping layer 213, which uses 6mm wide and 0.035mm thick PET wrapping tape with a shielding rate of 135%. The second PET wrapping layer 213 is covered by a second AL / MY wrapping layer 214, which uses 7mm wide and 0.035mm thick aluminum foil Mylar wrapping tape with a shielding rate of 135%. The second AL / MY wrapping layer 214 is covered by a second heat-fused wrapping tape 215 with a shielding rate of 135%. The multi-wrap structure, in which the aluminum foil Mylar wrapping tape has the function of single-sided conductivity and single-sided insulation, makes the second differential signal wire 21 have a good shielding effect and a good high-fidelity signal transmission effect.

[0043] The second audio transmission line 22 includes two second audio optical fibers 221. The two second audio optical fibers 221 are respectively made of OM1.5, OM2 or OM2+ single-mode fiber cores. Single-mode fiber transmission is used, and the signal is not affected by any external RFI / EMI interference. Two insulation structures are formed outside the fiber core, namely inner insulation made of FEP material and outer insulation made of HDPE material. The two second audio optical fibers 221 are twisted together and filled with 400D Kevlar* multi-bundle fiber. The two second audio optical fibers 221 are covered by a second ePTFE wrapping layer 222, which is 8mm wide and 0.005mm thick ePTFE wrapping tape with a wrapping tape shielding rate of 135%. A second intermediate layer 223 is formed outside the second ePTFE wrapping layer 222. The second intermediate layer 223 is made of vapor-phase compounded industrial-grade silicone rubber.

[0044] The second power line 23 uses 24AWG (19 / 0.12) tin-plated stranded copper wire as the conductor and TPEE material as insulation.

[0045] The second video control line 24 uses 26AWG (11 / 0.12) tin-plated stranded copper wire as the conductor and FEP material as insulation.

[0046] The second filling PE strip 25 has 1-3 strips, which are filled according to the actual roundness to ensure that the storage cable core is round as a whole.

[0047] The storage cable wrapping layer 26 includes a PET wrapping layer and an AL / MY wrapping layer. The PET wrapping layer uses 10mm wide and 0.035mm thick PET wrapping and covers the storage cable core, with a shielding rate of 135%. The AL / MY wrapping layer uses 12mm wide and 0.035mm thick aluminum foil Mylar wrapping and covers the PET wrapping layer, with a shielding rate of 135%. The aluminum foil Mylar wrapping has the function of being conductive on one side and insulating on the other, giving the storage cable 1 a good shielding effect and good high-fidelity signal transmission performance.

[0048] The storage line braided layer 27 is made of 8 spindles of 30AWG tin-plated copper foil wire and 8 spindles of tin-plated copper wire. The combined braiding greatly improves the softness and bending performance of the braid, while effectively isolating interference from external electromagnetic waves, robot equipment radiation sources and radio waves.

[0049] The storage line sheath 28 is made of TPU material. TPU sheaths have excellent high tensile strength and high tear resistance, high toughness and tear resistance, extremely strong bending resistance, and are also wear-resistant, cold-resistant, oil-resistant, water-resistant, aging-resistant, weather-resistant, and mildew-resistant. At the same time, they have windproof, cold-proof, heat-insulating, UV-resistant, and energy-releasing functions. Furthermore, they have high mechanical strength, strong load-bearing capacity, and good impact resistance and shock absorption performance.

[0050] The aforementioned storage line 2 can achieve a maximum data throughput of 80Gbps, covering both 40Gbps passive cables and the newly defined 80Gbps active cables. It is horizontally compatible with Thunderbolt 3 and backward compatible with USB 3.0 / USB 3.1 / USB 3.0 / USB 2.0. It supports better video and data bandwidth allocation, simultaneously transmitting video and data information during robot command operations, with 20% of the bandwidth used for video transmission and 80% for data transmission.

[0051] like Figure 7 As shown, the telescopic tube 3 includes a foamed insulator 31, the foamed insulator 31 is covered with a telescopic tube wrapping layer 33, the telescopic tube wrapping layer 33 is provided with a steel wire braided layer 34, and the steel wire braided layer 34 is provided with a telescopic tube inner layer 35.

[0052] The foamed insulator 31 is made of high-quality LDPE or modified PE material. The main raw material, polyethylene, is heated and foamed to 5-35 times its original size through electronic cross-linking technology to form a plate-shaped high-density foam. Multiple uniformly arranged 1.6mm hollow pipes 32 are formed on the foamed insulator 31 for connecting the air compressor pipes for inflation and deflation. This enables the intelligent vision robot to complete overall dynamic extension, contraction, and bending movements. Furthermore, through precise algorithm positioning, it can meet the robot's detailed precision movements and satisfy the requirements for intelligent and perfect positioning.

[0053] The telescopic tube wrapping layer 33 is made of PTFE tape. PTFE tape has high stability, high flame retardancy and low loss factor, weather resistance, heat resistance, low coefficient of friction, stable chemical properties, and good electrical insulation. It can keep the dielectric strength, dielectric constant, volume resistivity and surface resistivity of audio and video cable 1 and storage cable 2 in good condition. It has low moisture absorption, so that the dielectric performance of the cable is not affected by humidity at each level, and the cable maintains low attenuation under high temperature and pressure.

[0054] The steel wire braided layer 34 uses 8 0.2mm braided steel wires and is completed using a 16-spindle braiding machine. Each of the upper and lower spindles has 4 0.2mm steel wires. The 8 braided steel wires can withstand the motion force of the cable when it completes various movements, twists and turns and reciprocates.

[0055] The telescopic tube's inner layer 35 is made of TPU material. TPU material has excellent wear and tear resistance, is resistant to mineral oil, ozone, and aging (suitable for environments ranging from -45°C to +150°C), is radiation resistant, low-temperature resistant, UV resistant, chemical resistant, and has excellent biocompatibility (resistant to hydrolysis and microorganisms). It is odorless, has no volatiles, possesses excellent tensile and flexibility properties, and has high mechanical strength (even after exposure to 150°C hot air and high-temperature aging). It has good compatibility with other materials, good resilience, high waterproof rating, strong stain resistance, and its surface does not easily attract dust or become contaminated. It is ideally suited for the flexible multi-positional changes and reciprocating movements of intelligent vision robots, while also possessing superior resistance to torsional movements and continuous high-intensity operation during motion.

[0056] In addition, the silicone hose 4 is made of high elasticity and high tear resistance gas phase compounded transparent silicone as the main raw material, with an inner diameter of 4mm. It is also connected to the air compressor pipe for inflation and deflation. It coordinates visual information to control the relative position and posture of the robot end effector relative to the target or target features, thereby reducing grasping errors or mistakes and achieving the requirements of completing precise grasping actions.

[0057] The total filler material 5 is Kevlar 400D, which can enhance the mechanical tensile strength of the entire cable and reduce the sudden instantaneous tension of the cable under sudden external force during dynamic operation; it can also resolve the sudden torsional bending force and mechanical stress from different directions of the entire cable in the working state.

[0058] The bus wrapping layer 6 also has a two-layer structure, including a bus ePTFE wrapping layer and a bus AL / MY shielding wrapping layer. The bus ePTFE wrapping layer uses 45mm wide and 0.05mm thick ePTFE wrapping, and the bus AL / MY shielding wrapping layer uses 45mm wide and 0.025mm thick aluminum foil Mylar wrapping, with a coverage rate of 130%~135%. The ePTFE wrapping has excellent waterproof, moisture-permeable, and windproof properties. It is not corroded by any chemical reagents, does not absorb moisture, is non-flammable, and is extremely stable to oxygen and ultraviolet light, exhibiting excellent biological adaptability. The aluminum foil Mylar wrapping has the function of single-sided conductivity and single-sided insulation, which can resist noise interference and electromagnetic wave interference between devices, between cables, and between cables and devices, maintaining good signal transmission for the working environment and cable signal transmission.

[0059] The bus braided layer 7 is made of a mixture of tin-plated copper foil wire and tin-plated copper wire, and is operated by a 24-spindle high-speed silent braiding machine. Specifically, it is made of 8 bundles / 30AWG tin-plated copper foil wire + 16 / 10 / 0.12mm tin-plated copper wire. The combination braiding greatly improves the softness and bending and swaying performance of the braid, while effectively isolating the interference of external electromagnetic waves, robot equipment radiation sources and radio waves.

[0060] The outer sheath 8 of the bus is made of TPU, which has excellent high tensile strength and tear resistance, high toughness and tear resistance, extremely strong bending resistance, and is highly environmentally friendly. It is also wear-resistant, cold-resistant, oil-resistant, water-resistant, aging-resistant, weather-resistant, and mildew-resistant; simultaneously, it has windproof, cold-proof, heat-insulating, UV-resistant, and energy-releasing functions. Furthermore, it has high mechanical strength, strong load-bearing capacity, and outstanding impact resistance and shock absorption performance.

[0061] The aforementioned flexible motion cable for intelligent vision robots is specifically designed for use in intelligent vision robots, such as eight-axis intelligent vision welding robots, and offers the following advantages: 1. Integrate the audio / video cables and storage cables into a unified, integrated structure; 2. Three telescopic pipes and one silicone hose are set up at the same time. Both the telescopic pipes and the silicone hose can be used to connect to the air compressor branch pipe. By controlling the air compressor to continuously charge and deflate, the cable can be extended and bent. Combined with the robot's vision system, precise positioning can be achieved. The active movement of the cable can meet the robot's movement requirements, realize the robot's precise movement, and achieve the requirement of completing fine grasping action. 3. The conductors of both the first differential signal line and the second differential signal line are made of 28AWG silver-plated stranded copper wire, which has extremely fast transmission speed and extremely high conductivity. In addition, the structure of each layer of the audio and video line and the storage line is basically consistent in terms of material selection and manufacturing process, so that the two can find an optimal balance in the transmission of communication signals and form a stable consistency in operation. 4. The first and second audio transmission lines both use single-mode optical fiber transmission, so the signal is not affected by any external RFI / EMI interference; in addition, the audio and video lines, storage lines and bus all form multiple shielding effects, which can achieve high-fidelity signal transmission.
