Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically a novel robotic arm structure. Background Technology

[0002] A robotic arm is a complex system characterized by high precision, multiple inputs and outputs, high nonlinearity, and strong coupling. Due to its unique operational flexibility, it has been widely used in industrial assembly, safety and explosion protection, and other fields. As a complex system, a robotic arm exhibits uncertainties such as parameter perturbations, external interference, and unmodeled dynamics. Therefore, the modeling of a robotic arm also contains uncertainties. For different tasks, it is necessary to plan the motion trajectories of the robotic arm's joints in space, thereby cascading them to form the end effector pose.

[0003] Existing robotic arms have the following drawbacks:

[0004] 1. When using the existing robotic arm, it can only increase its height by extending its forearm. However, after the forearm is extended, some other operations cannot be performed, which affects the operation of the robotic arm.

[0005] 2. The existing robotic arms have limited extension length, which makes it impossible to operate on objects at a distance.

[0006] Therefore, a solution is needed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] Example 1

[0024] Regarding the problem 1 that needs to be solved above: When the existing robotic arm is in use, it can only increase its height by straightening its forearm, but some other operations cannot be performed after the forearm is straightened, which affects the operation of the robotic arm.

[0025] The solution is as follows: A novel robotic arm structure includes a device body 1, which comprises a mounting base 2, a lifting and rotating device 3, and an extension robotic arm device 4. The lifting and rotating device 3 is mounted on top of the mounting base 2, and the extension robotic arm device 4 is mounted on top of the lifting and rotating device 3. The lifting and rotating device 3 includes a rotating platform 5, a lifting column 6, and a top plate 7. The lifting column 6 is mounted on top of the rotating platform 5, and the top plate 7 is mounted on the top drive end of the lifting column 6. Two sets of pull rods 8 are arranged in a ring-shaped equidistant manner between the rotating platform 5 and the top plate 7. The rotating platform 5 includes a rotating outer shell 9, a rotating motor 10, and a rotating seat 11. The rotating platform 5 has a cylindrical structure and a hollow interior. The rotating seat 11 is located above the rotating outer shell 9, and a manual turntable is provided between the rotating outer shell 9 and the rotating seat 11. 12. The manual turntable 12 has a circular structure. The rotating motor 10 is installed inside the rotating housing 9. The top drive end of the rotating motor 10 is connected to the bottom of the rotating seat 11. When adjusting the height of the extended robotic arm device 4, the operator starts the lifting column 6 inside the lifting rotating device 3. The lifting column 6 pushes the top plate 7 to rise, and then the height of the extended robotic arm device 4 can be increased without affecting other operations of the extended robotic arm device 4. During the lifting process, the pull rod 8 can be pulled out, thereby improving the stability of the lifting of the top plate 7. If it is necessary to adjust the working angle of the extended robotic arm device 4, the operator starts the rotating motor 10 inside the rotating housing 9. The rotating motor 10 drives the rotating seat 11 to rotate on the manual turntable 12 through the drive shaft, and the angle of the extended robotic arm device 4 can be adjusted further.

[0026] The top plate 7 has a circular structure, and two sets of symmetrically distributed support columns 13 are provided on the top of the top plate 7. Support seats 14 are installed on the top of the two sets of support columns 13. The support seats 14 have a circular structure and are used to facilitate the fixing and installation of the extended robotic arm device 4.

[0027] The mounting base 2 has a circular shape. A side fixing ring 22 is provided on the bottom outer side of the mounting base 2. Several sets of reinforcing blocks 23 are distributed in a ring-shaped and equidistant manner between the side fixing ring 22 and the mounting base 2. The reinforcing blocks 23 have a triangular shape. Several sets of fixing holes 24 are distributed in a ring-shaped and equidistant manner on the surface of the side fixing ring 22. When the worker fixes the mounting base 2, the worker fits the side fixing ring 22 to the mounting point, inserts the bolt into the fixing hole 24 of the side fixing ring 22, and then the mounting base 2 can be fixed.

[0028] Example 2

[0029] Regarding the second problem to be solved above: the existing robotic arm has a limited extension length, which makes it impossible to operate on objects at a distance.

[0030] The solution is as follows: The extended robotic arm device 4 includes a first mounting block 15, a second mounting block 16, a transverse hydraulic rod 17, and a robotic gripper 18. The first mounting block 15 and the second mounting block 16 are distributed transversely at equal intervals. The transverse hydraulic rod 17 is installed in front of the first mounting block 15 and the second mounting block 16. A transverse tie rod 21 is provided between the first mounting block 15 and the second mounting block 16. A set of symmetrically distributed sleeve blocks 20 are sleeved on the transverse hydraulic rod 17. The robotic gripper 18 is installed at the bottom of the second mounting block 16. The second mounting block 16 has an L-shaped structure. A mechanical motor 19 is provided on the top of the second mounting block 16. The bottom drive end of the mechanical motor 19 is connected to the mechanical claw 18. During ultra-long-distance operation, the drive end of the transverse hydraulic rod 17 pushes the second mounting block 16 outward, thereby increasing the outward distance of the mechanical claw 18. Then the mechanical claw 18 grasps the object, and the transverse hydraulic rod 17 retracts, driving the second mounting block 16 and the mechanical claw 18 on the second mounting block 16 to retract. The mechanical claw 18 can be driven by the mechanical motor 19 to rotate.

[0031] Working principle: During operation, when adjusting the height of the extended robotic arm device 4, the operator starts the lifting column 6 inside the lifting and rotating device 3. The lifting column 6 pushes the top plate 7 to rise, thus raising the height of the extended robotic arm device 4 without affecting other operations. During the lifting process, the pull rod 8 can be pulled out, thereby improving the stability of the top plate 7. If it is necessary to adjust the working angle of the extended robotic arm device 4, the operator starts the rotating motor 10 inside the rotating housing 9. The rotating motor 10 drives the rotating seat 11 to rotate on the manual turntable 12 through the drive shaft, further adjusting the angle of the extended robotic arm device 4. During ultra-long-distance operations, the drive end of the horizontal hydraulic rod 17 pushes out the second mounting block 16, thereby increasing the outward distance of the robotic claw 18. Then, the robotic claw 18 grasps the object, and the horizontal hydraulic rod 17 retracts, driving the second mounting block 16 and the robotic claw 18 on the second mounting block 16 to retract. The robotic claw 18 can be driven by the mechanical motor 19 to rotate.

The problem solved by this utility model is that existing robotic arms can only increase their height by straightening their forearms, but some other operations cannot be performed after the forearms are straightened, which affects the operation of the robotic arm. This utility model can effectively increase the height of the robotic arm by combining the above-mentioned components, without affecting the normal operation of the robotic arm and robotic gripper. With such a device, the workload of the workers can also be reduced.
