Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a foldable carbon fiber robotic arm. Background Technology

[0002] In modern industrial production, in order to improve production efficiency, product quality and stability, and reduce labor costs, the degree of industrial automation is constantly increasing. Industrial robots are widely used in many industries such as automobile manufacturing, metal products, electronics, and logistics warehousing. They need to complete a variety of tasks such as dispensing, welding, spraying, handling, assembly, and inspection. In some complex production scenarios, robotic arms need to have flexible movement capabilities and compact storage methods to adapt to different workspaces and task requirements. The design of folding robotic arms can meet these requirements. Traditional robotic arms made of metal materials have problems such as heavy weight, large inertia, and poor repeatability. With the development of materials science, carbon fiber composite materials have attracted attention due to their advantages of high strength, corrosion resistance, impact resistance, and light weight. Using carbon fiber composite materials to make robotic arms can not only significantly reduce the weight of the robotic arm, but also ensure that it has good static and dynamic performance, improve the load-to-weight ratio, meet the requirements of high-speed and high-precision operation of industrial robots, and reduce energy consumption.

[0003] When not in use, the foldable carbon fiber robotic arm can be folded up for maximum storage, reducing its footprint and improving storage efficiency. This is particularly beneficial for workplaces with limited space, facilitating storage and management and improving space utilization. The folded robotic arm is smaller in size, making it easier to handle and transport, reducing space occupation and damage risks during transportation. It is also more convenient to operate when installed in different work locations or on different equipment, allowing it to more easily pass through narrow passages or doorways to reach the designated installation location. In existing technologies, a motor drives a transmission gear to rotate, which in turn drives a transmission rack to move, causing the sliding arm to move the electric mechanical gripper, ultimately achieving the folding effect. However, there is an unavoidable gap between the gear and the rack. During the folding and unfolding of the robotic arm, these gaps can lead to inaccuracy in motion transmission, making it difficult for the end effector of the robotic arm to accurately reach the predetermined position, thus affecting operational accuracy.

[0034] Specifically, the folding mechanism 2 greatly improves its applicability in confined spaces, and the mounting mechanism 3 makes the process of installing the gripper on the robotic arm extremely simple and quick, greatly improving work efficiency.

[0035] Rotating column 201 is rotatably connected to robotic arm 1, ensuring the stability and reliability of the robotic arm during the folding process. Robotic arm 202 allows the robotic arm to fit tightly when folded, maintaining overall compactness. Limiting component 203 provides precise positioning when the robotic arm is folded to a specific position, ensuring the accuracy of operation. Limiting column 2041 is slidably connected to robotic arm 202, allowing limiting column 2041 to move freely within a certain range to adapt to different operational needs. Limiting ring 2042 effectively prevents limiting column 2041 from accidentally slipping off during use, ensuring the safety of the robotic arm in complex working environments.

[0036] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 5 The installation mechanism 3 includes a locking block 301, the left side of which is fixedly connected to the right side of the second robotic arm 202.

[0037] Specifically, the left side of the locking block 301 is fixedly connected to the second robotic arm 202, ensuring the stability and accuracy of the second robotic arm 202 when performing tasks. The push block 302 can not only respond flexibly to the operator's instructions, but also has a guide component 303 on its inner wall to ensure the smoothness and accuracy of the push block 302 during movement. The reset component 304 allows the entire mechanism to quickly return to the initial state after the operation is completed, preparing for the next operation. The telescopic rod 2052 allows the first robotic arm 1 to adjust its length as needed, thereby adapting to different working environments. The second sliding block 2053 further enhances the flexibility and operating range of the second robotic arm 202.

[0038] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The limiting component 203 includes a limiting post 2031, the outer wall of the limiting post 2031 is slidably connected to the middle of the inner wall of the robotic arm 1, the front and rear sides of the outer wall of the limiting post 2031 are threaded with limiting rings 2032, the upper and lower sides of the middle of the outer wall of the robotic arm 1 are provided with limiting holes 2033, the bottom of the robotic arm 1 is fixedly connected with a bottom block 4, and the bottom of the outer wall of the robotic arm 1 is provided with a hollow groove 5.

[0039] Specifically, the limiting component 203 ensures the stability and operational precision of the robotic arm 1. The limiting post 2031 is slidably connected to the robotic arm 1, ensuring smooth movement of the limiting post 2031 within the robotic arm 1. The internal threads of the limiting post 2031 and the limiting ring 2032 are tightly fitted, allowing the limiting ring 2032 to be securely fixed on the limiting post 2031, thereby achieving effective control over the range of motion of the robotic arm 1. The bottom block 4 not only enhances the stability of the robotic arm 1 but also provides an additional support point for the entire robotic arm 1. The hollow groove 5 reduces the overall weight of the robotic arm 1.

[0040] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The guide component 303 includes a mounting block 3031, the outer wall of the mounting block 3031 is slidably connected to the inner wall of the engaging block 301, guide rails 3032 are provided on the front and rear sides of the outer wall of the mounting block 3031, and fixing blocks 3033 are fixedly connected to the upper and lower sides of the outer wall of the mounting block 3031. The reset component 304 includes a spring post 3041, the outer wall of the spring post 3041 is fixedly connected to the left side of the inner wall of the mounting block 3031, and engaging posts 3042 are fixedly connected to both ends of the spring post 3041.

[0041] Specifically, the guide component 303 ensures the precise movement and positioning of the mechanical parts; the mounting block 3031 and the locking block 301 are slidably connected to ensure the smoothness and stability of the movement; the guide rail 3032 avoids any unnecessary deviations; the fixing block 3033 not only enhances the overall stability of the component but also ensures that the spring column 3041 is fixedly connected to the mounting block 3031 under various working environments, ensuring the uniform transmission of the reset force; and the locking column 3042 ensures that the mechanical parts can accurately return to the initial position after completing the task.

[0042] Working principle: Rotate the two limiting rings 2042 and 2032 on both sides, and pull out the two limiting posts 2041 and 2031. Then, the sliding block 2051 and the sliding block 2053 lose their limit. Then, press down on the robotic arm 202 and activate the telescopic rod 2052. The telescopic rod 2052 will retract, thereby pulling the robotic arm 202, so that the robotic arm 202 rotates around the outer wall of the rotating post 201 and fits the robotic arm 202 more closely with the robotic arm 1. Then, the sliding block 2051 and the sliding block 2053 will slide to the positions of the limiting hole 2033 and the limiting hole 2043 respectively. Then, insert the limiting post 2031 and the limiting post 2041 to limit them. This can realize the folding of the robotic arm, which facilitates the transportation and storage of the robotic arm and improves the space utilization rate.

[0043] When the clamping claw needs to be installed, fix the clamping claw to the right side of the mounting block 3031, align the guide rail 3032 with the inner wall of the locking block 301, and push the mounting block 3031 so that the mounting block 3031 slides along the outer wall of the guide rail 3032 toward the inner wall of the locking block 301. When the right side of the locking block 301 touches the fixing block 3033, it stops. At this time, the spring column 3041 will pop out the locking columns 3042 on both sides and squeeze out the push block 302 inside the locking block 301. Then, part of the locking column 3042 will be locked into the interior of the locking block 301. When disassembly is required, press the push block 302 to disassemble. This realizes the installation and disassembly of the clamping claw, simplifies the use process, facilitates the use of the staff, and improves the practicality of the equipment.
