Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to an intelligent industrial robotic arm. Background Technology

[0002] In industrial production and outdoor operations, manual operation is easily restricted by the environment and carries high risks. When using drones to carry traditional actuators, the functions are limited and the adaptability is insufficient. Therefore, intelligent industrial robotic arms are set up to cooperate with drones to achieve high-altitude precision grasping, equipment component installation and disassembly, emergency material delivery and other operations. To a certain extent, this makes up for the limitations of manual operation in high-risk and complex scenarios and improves the automation level and reliability of related operations.

[0003] A search revealed Chinese patent publication number CN223507183U, which discloses a drone robotic arm. The arm comprises a mounting base, several arms, and a mounting frame. The arms are rotatably connected end-to-end. One end of one arm in the arm assembly is rotatably connected to the mounting base. The arms cooperate to form a multi-axis rotation with at least three degrees of freedom, and all arms are driven by motors. The mounting frame is mounted on one end of one arm at the other end of the arm assembly and is used to mount maintenance tools. This application features multiple mutually rotating arms in different directions that cooperate, while simultaneously adjusting the drone's altitude, allowing the mounting frame at the end to reach any part of three-dimensional space. Combined with the maintenance tools on the mounting frame, it enables the repair of power transmission lines in complex environments.

[0004] The aforementioned patent has the following shortcomings: Since the existing robotic arm is directly installed on the bottom of the drone, the overall size of the robotic arm after unfolding is large and the shape is fixed, which means that it needs to occupy a large storage space during transportation. When stored, it is easy to cause damage to the arm or joint components due to external collisions, which affects the accuracy of subsequent operations. At the same time, when not in operation, the robotic arm increases the overall size and wind resistance of the drone, which reduces flight stability and endurance to a certain extent.

[0005] To address this, an intelligent industrial robotic arm is proposed. Utility Model Content

As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0025] Example 1: like Figures 1 to 5 As shown, an intelligent industrial robotic arm includes a main arm 1, and also includes: The rotating base 10 is rotatably connected to the outer side of the top end of the main arm 1. A second geared motor 9 with the output shaft end connected to the main arm 1 is installed on one side of the rotating base 10. Storage structure 2 is set at the top of the rotating base 10. Storage structure 2 includes a mounting plate 205 that is fixed to the top of the rotating base 10 by threads. Rotating frame 204 is fixed on both sides of the bottom end of the mounting plate 205. Storage shell 201 is fixed at the top of the rotating frame 204. Power components are provided on both sides of the mounting plate 205. An extension structure 8 for adjusting the length of the robotic arm is located at the bottom end inside the main arm 1. The first flipping arm 3 is located at the bottom end of the extension structure 8. The second flipping arm 5 is rotatably connected to one side of the first flipping arm 3, and the bottom end of the second flipping arm 5 is fixed with a gripper 7. A locking structure 6 is provided at the top of the gripper 7 to prevent the part from falling off the gripper 7.

[0026] A third geared motor 11 is installed on one side of the first tilting arm 3, and a first geared motor 4 with its output shaft end connected to the second tilting arm 5 is installed on the side of the first tilting arm 3.

[0027] In this embodiment, the second reduction motor 9 is started to drive the main arm 1 to rotate around the fixed rotating seat 10, and the angle of the main arm 1 is adjusted. The third reduction motor 11 is started to drive the first flip arm 3 to rotate around the extension frame 801, and the position of the first flip arm 3 is adjusted. The first reduction motor 4 drives the second flip arm 5 to rotate around the first flip arm 3, so that the gripper 7 can be aligned with the object to be gripped. After the operation is completed, the first reduction motor 4 drives the second flip arm 5 to rotate and retract into the first flip arm 3. At the same time, the third reduction motor 11 drives the first flip arm 3 to rotate and fit with the main arm 1 and the extension frame 801, thereby completing the retraction action of the main structure.

[0028] like Figures 1 to 5 As shown, the power assembly includes a guide rod 206 fixed to one side of the top of the mounting plate 205. The storage shell 201 has guide grooves 203 on both sides that are slidably connected to the guide rod 206. The storage shell 201 is rotatably connected to the two sides of the first electric actuator 202. The guide rod 206 extends through the guide groove 203 to the outside of the storage shell 201 and is connected to the telescopic end of the first electric actuator 202. The telescopic end of the first electric actuator 202 and the guide rod 206 form a rotating structure.

[0029] In this embodiment, when the robotic arm needs to be further stored after it has been retracted, the first electric actuator 202 is activated to retract, causing it to pull the mounting plate 205 around the rotating frame 204 via the guide rod 206 and move it into the storage shell 201. At the same time, the guide rod 206 slides inside the guide groove 203 to guide and limit the movement of the mounting plate 205, so that the retracted robotic arm can be stored inside the storage shell 201, further reducing the overall size of the device and reducing the risk of damage to components during transportation and storage.

[0030] Example 2: An intelligent industrial robotic arm, this embodiment is based on embodiment 1 with the following improvements, such as... Figures 1 to 5As shown, the extension structure 8 includes a drive motor 805 fixed inside the main arm 1. A base frame 802 is fixed at the bottom inside the main arm 1. A screw 806 connected to the output shaft end of the drive motor 805 is rotatably connected to the top of the base frame 802. A movable frame 804 is threadedly connected to the outside of the screw 806. Extension frames 801 rotatably connected to the first tilting arm 3 are fixed on both sides of the movable frame 804. Slide rods 803 slidably connected to the movable frame 804 are fixed on both sides of the top of the base frame 802. The output shaft end of the third reduction motor 11 extends into the interior of the first tilting arm 3 and is connected to the extension frame 801. The extension frame 801 and the main arm 1 form a sliding structure.

[0031] In this embodiment, when the work scenario requires adjustment of the robotic arm length, the drive motor 805 is started to drive the screw 806 to rotate, so that the moving frame 804 moves smoothly up and down along the screw 806, thereby driving the extension frame 801 to extend or retract synchronously, which expands the work coverage to a certain extent, allowing the gripper 7 to reach work positions at a distance or a specific height, making the device more flexible in complex work environments. The slide bar 803 guides the movement of the moving frame 804.

[0032] like Figures 1 to 5 As shown, the locking structure 6 includes a second electric push rod 601 fixed inside the second flipping arm 5. A movable plate 604 is fixed to the telescopic end of the second electric push rod 601. Push arms 602 are rotatably connected to both sides of the movable plate 604. Connecting arms 603 are rotatably connected to the top ends of both sides of the gripper 7. A support plate 605 is fixed to one side of the connecting arm 603. The connecting arm 603 is rotatably connected to the middle section of the connecting arm 603 by a pin. The connecting arms 603 are symmetrically distributed on the vertical center line of the gripper 7.

[0033] In this embodiment, after the gripper 7 completes the gripping of the object, the second electric push rod 601 is activated to push the moving plate 604 to move, so that the moving plate 604 drives the connecting arm 603 to rotate via the push arm 602. At the same time, the support plate 605 flips towards the object and fits to support it, thereby realizing the object anti-drop function and ensuring the safety and reliability of the operation.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
