[0017] The following further elaborates on the present utility model in detail in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0018] Embodiment

[0019] Please refer to Figures 1 to 3 , in this embodiment, a robotic arm for a riveting machine is provided, including a support 1. A mounting seat 2 is provided at the top of the support 1. A rotating mechanism is fixedly provided on one side of the mounting seat 2. The rotating mechanism serves as a power source. A moving rod 9 is provided on the front side thereof. The moving rod 9 is arranged vertically. At the same time, a limit chute 7 is opened on the front side wall of the rotating mechanism. The limit chute 7 is used to limit the movement of the moving rod 9 so that it can move along the track of the limit chute 7. The limit chute 7 is arranged in a "冂" - shaped structure;

[0020] Moreover, a slide block 10 is sleeved on the moving rod 9. The side wall of the slide block 10 is slidably connected to a slide rail 11. The slide rail 11 is arranged horizontally and is installed at the bottom of the rotating mechanism. A claw 12 is installed at the bottom of the moving rod 9. The claw 12 moves along with the movement of the moving rod 9;

[0021] Specifically, the rotating mechanism includes a rear cover 3 which is arranged on the mounting base 2. The front side of the rear cover 3 is provided as a front cover 4. An eccentric wheel 5 is arranged inside the rear cover 3 and the front cover 4. The eccentric wheel 5 is connected to an external moving rod 9. The eccentric wheel 5 is of a triangular structure. A servo motor 6 is further arranged on the rear side of the rear cover 3. The output shaft of the servo motor 6 is connected to the eccentric wheel 5. At the same time, a limiting sliding groove 7 is formed on the side wall of the front cover 4, and a sliding rail 11 is arranged on the rear cover 3.

[0022] When the robotic arm is working, the servo motor 6 is started, which can drive the eccentric wheel 5 to rotate. After the eccentric wheel 5 rotates, the moving rod 9 will move accordingly (it should be noted here that the connecting rod used to connect the eccentric wheel 5 and the moving rod 9 is the rod that slides in the limiting sliding groove 7 and is not shown in the attached drawing. Any existing smooth rod can be used). Due to the limiting effect of the limiting sliding groove 7 and the cooperation with the slider 10 sliding on the sliding rail 11, the moving rod 9 can only move along the limiting sliding groove 7 in a "冂"-shaped trajectory.

[0023] [[ID=--6]]The height of its two side edges is the height of the rising or falling of the moving rod 9, and the horizontal length thereof is the horizontal moving distance of the moving rod 9, that is, the trajectory of the movement of the clamping jaw 12. Thus, after the clamping jaw 12 clamps an item from one place, it can move to another place, realizing the function of automatic clamping. By the forward or reverse rotation of the servo motor 6, the clamping jaw 12 can move back and forth. At the same time, a sensor 8 is arranged at one end point on one side of the limiting sliding groove 7 on the front cover 4. The sensor 8 is used for signal point positioning. When the moving rod 9 moves to this side, it receives the signal and feeds it back to the servo motor 6. At this time, the servo motor 6 will reverse to make it return.

[0024] The robotic arm of the present utility model utilizes the mutual cooperation of structures such as the servo motor 6, the triangular eccentric wheel 5, the limiting sliding groove 7, the moving rod 9, the slider 10, and the sensor 8, enabling the clamping jaw 12 at the bottom of the moving rod 9 to realize the function of clamping and placing items. Its structure is simple, with automated operation, having good practicability, and being applicable to various automated devices, especially in riveting machines. It replaces manual labor and can significantly improve the operation efficiency.

[0025] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in the art.
