Description

Technical Field

[0001] This utility model relates to the field of bionic arm technology, specifically to a human-machine collaborative intelligent bionic arm. Background Technology

[0002] Human-machine collaboration refers to a working mode in which humans and intelligent devices or systems such as computers and robots cooperate closely and complement each other's strengths to jointly complete specific tasks or goals. This mode is not simply about humans operating machines or machines assisting humans, but emphasizes the deep interaction and collaborative evolution of the two in perception, decision-making, and execution. The human-machine collaborative intelligent bionic arm is an advanced device that integrates multiple disciplines such as bionics, artificial intelligence, and mechanical engineering. It aims to simulate the structure and function of the human arm to achieve efficient collaborative work with humans. By drawing on the structure and movement principles of the human arm's bones, muscles, joints, etc., and adopting a multi-joint design and a muscle-like driving method, the robotic arm has similar flexibility and movement capabilities to the human arm. In the industrial manufacturing process, the bionic arm collaborates with workers to complete various tasks on the production line, such as parts assembly, material handling, and quality inspection, which can improve production efficiency, reduce labor intensity, and ensure the stability of product quality.

[0003] While existing bionic arms offer numerous benefits, they still suffer from several drawbacks. Firstly, their protection is inadequate. Secondly, during use in manufacturing environments, goods or equipment may accidentally come into contact with the bionic arm, making it susceptible to damage and impacting its lifespan. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a human-machine collaborative intelligent bionic arm.

[0005] The technical solution adopted by this utility model to solve its technical problem is a human-machine collaborative intelligent bionic arm, including a fixed base, a protective cover and a heat-conducting plate. The mechanical arm is arranged on the outside of the fixed base. The outer walls of both sides of the mechanical arm are provided with protective covers. The opposing surfaces of the two protective covers are glued and fixed with first buffer pads. The inner side of the protective cover is provided with an assembly plate distributed in a rectangular array. The outer wall of the assembly plate is welded with threaded columns. The inner wall of the protective cover is screwed to a heat-conducting plate. The outer side of the heat-conducting plate is welded with equally spaced parallel heat dissipation fins.

[0006] By adopting the above technical solutions, the fixed base provides a stable installation foundation for the robotic arm, ensuring the stability of the robotic arm's position during operation. The protective cover protects the robotic arm from collisions in the external environment. The first buffer pad can mitigate the impact when an external object impacts the protective cover laterally, and the second buffer pad can mitigate the impact when an external object impacts the protective cover longitudinally. This provides comprehensive protection for the outer side of the robotic arm, reducing the damage caused by impacts and improving the safety and service life of the equipment. The heat-conducting plate can transfer the temperature generated by the servo motors used at both ends of the robotic arm during operation and dissipate the heat through the heat dissipation fins, preventing heat accumulation inside the robotic arm and further improving the reliability and service life of the robotic arm.

[0007] Specifically, the lower end of the robotic arm is provided with a connecting seat, and the robotic arm is rotatably connected to the fixed seat.

[0008] By adopting the above technical solution, the robotic arm and the fixed base are driven to rotate by a servo motor, which can adjust the operating angle of the robotic arm relative to the outside of the fixed base, ensuring the working range and freedom of movement of the robotic arm. The robotic arm can be connected to the matching gripper through the connecting seat.

[0009] Specifically, a second buffer pad distributed in a rectangular array is bonded and fixed to the inner wall of the protective cover. Both the protective cover and the second buffer pad have arc-shaped holes inside. The threaded post is located inside the arc-shaped hole. The second buffer pad is in contact with the outer wall of the assembly plate. The assembly plate is connected to the outer wall of the robotic arm by screws.

[0010] By adopting the above technical solution, the second buffer pad supports the gap between the protective cover and the robotic arm and can alleviate the longitudinal impact force when the protective cover is subjected to it, ensuring the protective effect of the protective cover on the robotic arm. The arc-shaped hole allows the protective cover to be displaced when it is subjected to lateral impact, ensuring the buffering performance.

[0011] Specifically, a protective pad is fitted on the outside of the threaded post, the protective pad is located outside the protective cover, and a fastening nut is threaded onto the threaded post away from the outside of the protective pad.

[0012] By adopting the above technical solution, the protective pad avoids contact between the fastening nut and the protective cover, so that while the fastening nut maintains the position of the protective cover, the protective cover can move outside the threaded column through the arc-shaped hole.

[0013] Specifically, thermally conductive silicone pads are bonded and fixed to the outer walls of both the upper and lower sides of the heat-conducting plate. The thermally conductive silicone pads are distributed on the upper and lower sides of the heat dissipation fins and are in contact with the outer wall of the robotic arm.

[0014] By adopting the above technical solution, the thermally conductive silicone pad has good thermal conductivity and can fill the gap between the heat-conducting plate and the robotic arm, thereby conducting heat between the heat-conducting plate and the robotic arm. It can effectively transfer the heat inside the robotic arm to the heat-conducting plate, and then dissipate it through the heat dissipation fins, ensuring heat dissipation efficiency.

[0015] Specifically, the outer wall of the heat-conducting plate is provided with second ventilation holes that are equally spaced and parallel, and the second ventilation holes and the heat dissipation fins are designed in an alternating manner. The outer wall of the protective cover is provided with first ventilation holes that are adapted to the number of second ventilation holes, and the positions of the first through holes and the second ventilation holes are corresponding.

[0016] By adopting the above technical solution, the first through hole and the second ventilation hole facilitate the airflow between the protective cover and the heat conduction plate. When the air flows through the heat dissipation fins, it can carry away heat and ensure the heat dissipation effect.

[0017] The beneficial effects of this utility model are: The present invention describes a human-machine collaborative intelligent bionic arm. The first buffer pad can mitigate the impact force when an external object collides laterally with the protective cover, and the second buffer pad can mitigate the impact force when an external object collides longitudinally with the protective cover. This provides comprehensive protection for the outer side of the robotic arm, reduces the damage caused by impact forces, and improves the safety and service life of the equipment.

[0018] The present invention describes a human-machine collaborative intelligent bionic arm. The heat-conducting plate can transfer the temperature generated by the servo motors used at both ends of the robotic arm during operation, and the heat is dissipated through heat dissipation fins, which prevents heat accumulation inside the robotic arm and further improves the reliability and service life of the robotic arm.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention discloses a human-machine collaborative intelligent bionic arm, comprising a fixed base 1, a protective cover 2, and a heat-conducting plate 3. A robotic arm 11 is disposed on the outer side of the fixed base 1, and protective covers 2 are disposed on both outer walls of the robotic arm 11. A first buffer pad 22 is bonded and fixed to the opposite surfaces of the two protective covers 2. An assembly plate 23 with a rectangular array is disposed on the inner side of the protective cover 2. Threaded posts 25 are welded to the outer wall of the assembly plate 23. A heat-conducting plate 3 is screwed to one side of the inner wall of the protective cover 2. Heat dissipation fins 31 with equal spacing and parallel distribution are welded to the outer side of the heat-conducting plate 3.

[0024] During use, the fixed base 1 provides a stable mounting foundation for the robotic arm 11, ensuring the stability of the robotic arm 11 during operation. The protective cover 2 protects the robotic arm 11 from collisions in the external environment. The first buffer pad 22 can mitigate the impact when an external object impacts the protective cover 2 laterally, and the second buffer pad 24 can mitigate the impact when an external object impacts the protective cover 2 longitudinally. This provides comprehensive protection for the outside of the robotic arm 11, reducing the damage caused by impacts and improving the safety and service life of the equipment. The heat-conducting plate 3 can transfer the temperature generated by the servo motors used at both ends of the robotic arm 11 during operation and dissipate the heat through the heat dissipation fins 31, preventing heat accumulation inside the robotic arm 11 and further improving the reliability and service life of the robotic arm 11.

[0025] To ensure stable use, for example, such as Figure 1 As shown, a connecting seat 12 is provided at the lower end of the robotic arm 11, and the robotic arm 11 is rotatably connected to the fixed seat 1.

[0026] In use, the robotic arm 11 is driven to rotate by a servo motor, which can adjust the working angle of the robotic arm 11 relative to the outside of the fixed base 1, ensuring the working range and freedom of movement of the robotic arm 11. The robotic arm 11 can be connected to the matching gripper through the connecting seat 12.

[0027] To mitigate the impact, for example, such as Figure 2 As shown, a second buffer pad 24 distributed in a rectangular array is bonded and fixed to the inner wall of the protective cover 2. Both the protective cover 2 and the second buffer pad 24 have arc-shaped holes inside. The threaded post 25 is located inside the arc-shaped hole. The second buffer pad 24 is in contact with the outer wall of the assembly plate 23. The assembly plate 23 is connected to the outer wall of the robotic arm 11 by screws.

[0028] In use, the second buffer pad 24 supports the gap between the protective cover 2 and the robotic arm 11 and can alleviate the longitudinal impact force on the protective cover 2, ensuring the protective effect of the protective cover 2 on the robotic arm 11. The arc-shaped hole allows the protective cover 2 to be displaced when it receives a lateral impact, ensuring the buffering performance.

[0029] To maintain the usage location, for example, such as Figure 3 As shown, a protective pad 26 is fitted on the outside of the threaded post 25. The protective pad 26 is located outside the protective cover 2. A fastening nut 27 is threadedly connected to the threaded post 25 away from the outside of the protective pad 26.

[0030] When in use, the protective pad 26 prevents the fastening nut 27 from contacting the protective cover 2, so that the fastening nut 27 maintains the position of the protective cover 2 while allowing the protective cover 2 to move outside the threaded post 25 through the arc-shaped hole.

[0031] For heat conduction, for example, such as Figure 3 As shown, thermally conductive silicone pads 33 are bonded and fixed to the outer walls of both the upper and lower sides of the heat-conducting plate 3. The thermally conductive silicone pads 33 are distributed on the upper and lower sides of the heat dissipation fins 31, and the thermally conductive silicone pads 33 are in contact with the outer wall of the robotic arm 11.

[0032] When in use, the thermally conductive silicone pad 33 has good thermal conductivity and can fill the gap between the heat-conducting plate 3 and the robotic arm 11, thereby conducting heat between the heat-conducting plate 3 and the robotic arm 11. It can effectively transfer the heat inside the robotic arm 11 to the heat-conducting plate 3, and then dissipate it through the heat dissipation fins 31, ensuring heat dissipation efficiency.

[0033] For ventilation and heat dissipation, for example, such as Figure 3As shown, the outer wall of the heat-conducting plate 3 has equidistant parallel second ventilation holes 32. The second ventilation holes 32 and the heat dissipation fins 31 are designed in an alternating manner. The outer wall of the protective cover 2 has first ventilation holes 21 adapted to the number of second ventilation holes 32, and the positions of the first through holes and the second ventilation holes 32 are corresponding.

[0034] During use, the first through hole and the second ventilation hole 32 facilitate the flow of air between the protective cover 2 and the heat conduction plate 3. When the air flows through the heat dissipation fins 31, it can carry away heat and ensure the heat dissipation effect.

[0035] In use, the bionic arm is mounted on the work platform via the fixed base 1. The connecting base 12 at the lower end of the robotic arm 11 is connected to the execution terminal. The servo motor between the fixed base 1 and the robotic arm 11 drives the robotic arm 11 to rotate to the target position. The connecting base 12 ensures that the end effector is accurately aligned with the object being operated. The staff fixes the assembly plate 23 to the robotic arm 11 with screws. At this time, the protective cover 2 moves to the outside of the robotic arm 11. The staff manually rotates the fastening nut 27 so that the fastening nut 27 squeezes the protective cover 2 through the protective pad 26. The second buffer pad 24 keeps the protective cover 2 in place on the outside of the robotic arm 11. When a lateral impact force is applied to the protective cover 2, the opposing first buffer pads 22 compress and deform to absorb energy; during a longitudinal impact, the second buffer pad 24 buffers energy through the elastic deformation of the arc-shaped hole, while the distance between the heat dissipation fins 31 and the robotic arm 11 is greater than the movement limit of the protective cover 2 when subjected to impact force. The heat generated by the servo motor inside the robotic arm 11 is transferred to the heat-conducting plate 3 through the thermally conductive silicone pad 33. The heat dissipation fins 31 increase the heat dissipation area. Air flows in from the first ventilation hole 21, passes through the second ventilation hole 32 and sweeps over the heat dissipation fins 31, carrying away the heat and forming natural convection heat dissipation.
