In these scenarios, the robotic arm can quickly respond to the production cycle, accurately grasp and handle workpieces of different specifications and shapes, realize the automation and intelligence of the production process, significantly improve production efficiency, reduce labor costs, and ensure production safety and product quality stability.

[0003] However, existing technologies still have the following problems:

[0004] In existing technologies, most workpiece handling methods often suffer from problems such as inaccurate positioning and poor flexibility. This makes it difficult to quickly and accurately grab and move workpieces in different positions during automated handling on the production line. This not only reduces production efficiency and increases the production cycle, but may also cause workpiece damage or handling failure due to positioning errors, thereby affecting product quality and the overall stability of the production line.

[0005] To address the aforementioned problems, the inventors proposed a robotic arm for rapid workpiece handling in production line automation. Utility Model Content

[0016] 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.

[0017] Example: Figure 1-3 As shown, this utility model provides a robotic arm for rapid workpiece handling in automated production lines, including a support frame 1. A moving mechanism 2 is fixedly mounted on the upper end of the support frame 1, and a clamping mechanism 3 is mounted on the lower surface of the moving mechanism 2. The moving mechanism 2 includes a moving frame 20, the lower surface of which is fixedly connected to the support frame 1. A motor 23 is fixedly mounted on one end of the moving frame 20, and a threaded rod 28 is fixedly mounted on the output end of the motor 23. A moving plate 29 is threadedly fitted on the outer side of the threaded rod 28. Limiting rods 21 are fixedly mounted on both sides of the moving plate 29, and one end of the limiting rod 21 slides in cooperation with the two sides of the moving frame 20. A connecting frame 27 is fixedly mounted on the lower surface of the moving plate 29, and a lifting cylinder 26 is fixedly mounted on the upper inner wall of the connecting frame 27. The output end of the lifting cylinder 26 is fixedly connected to the clamping mechanism 3. During the rapid workpiece handling process in automated production lines, the moving mechanism 2 starts to work. When motor 23 starts, its output drives the threaded rod 28 to rotate. Since the moving plate 29 is threaded onto the outside of the threaded rod 28, and the limiting rods 21 on both sides slide against the limiting grooves 24 on both sides of the moving frame 20, the moving plate 29 moves stably horizontally along the limiting rods 21 under the rotation of the threaded rod 28. During the movement of the moving plate 29, the connecting frame 27 on the lower surface moves along with it, and the lifting cylinder 26 on the inner wall of the connecting frame 27 also moves accordingly. When it is necessary to adjust the vertical position of the clamping mechanism 3, the lifting cylinder 26 starts, and its output drives the clamping mechanism 3 to move up and down, thereby adjusting the position of the clamping mechanism 3 in both the horizontal and vertical directions to accurately reach the target workpiece position for clamping.

[0018] The clamping mechanism 3 includes a clamping frame 30, the upper surface of which is fixedly connected to the output end of the lifting cylinder 26. Two rotating slots 36 are provided on both sides of the clamping frame 30. A limiting clamping plate 35 and a clamping clamping plate 34 are respectively rotatably mounted on the inner side of each pair of rotating slots 36. A clamping cylinder 32 is provided on one side of the clamping frame 30. A rotating rod 33 is provided at the output end of the clamping cylinder 32. The lower end of the rotating rod 33 is rotatably connected to one side of the clamping clamping plate 34. When the clamping mechanism 3 reaches the target workpiece position via the moving mechanism 2, the clamping mechanism 3 begins to perform the clamping action. The clamping cylinder 32 is activated, and its output end drives the rotating rod 33 to move. The lower end of the rotating rod 33 is rotatably connected to one side of the clamping clamping plate 34, causing the clamping clamping plate 34 to rotate within the rotating slot 36, moving closer to the workpiece and clamping it. Simultaneously, the limiting clamping plate 35 plays a role in auxiliary positioning and limiting within the rotating slot 36, preventing the workpiece from shifting or falling during the clamping process. The damping ring 37 inside the rotating groove 36 is rotatably connected to the limiting clamping plate 35 and one side of the clamping clamping plate 34, increasing the damping when the clamping plates rotate, making the clamping action more stable and precise. After clamping is completed, the clamping mechanism 3 moves to the designated position along with the moving mechanism 2 to put down the workpiece.

[0019] The mounting bracket 22 fixed on one side of the movable frame 20 is fixedly engaged with the motor 23, providing a stable mounting position for the motor 23. This ensures that the motor 23 will not shift due to vibration or external force during operation, guaranteeing the stability and reliability of the motor 23's operation, and thus ensuring the normal operation of the movable mechanism 2. The limiting grooves 24 on both sides of the movable frame 20 slide against the limiting rods 21, restricting the freedom of the movable plate 29 during horizontal movement. This restricts its movement to the direction of the limiting rods 21, preventing the movable plate 29 from shifting or wobbling during movement. This improves the accuracy of the movable mechanism 2's horizontal positioning, ensuring that the clamping mechanism 3 can accurately reach the target position. The two sets of slide rails 25 fixed to the lower surface of the movable frame 20 are fixedly connected to the connecting frame 27, providing more stable support and guidance for the movement of the connecting frame 27. The slide rail 25 can reduce the friction when the connecting frame 27 moves, making the movement of the connecting frame 27 smoother. It can also further improve the stability of the movement of the connecting frame 27, which helps the clamping mechanism 3 to be accurately positioned and operate stably in the horizontal and vertical directions.

[0020] A fixed bracket 31 on one side of the clamping frame 30 is fixedly connected to the clamping cylinder 32, providing a reliable mounting base for the clamping cylinder 32. This ensures that the clamping cylinder 32 can stably output power during operation, preventing its own shaking or displacement from affecting the accuracy of the clamping action and guaranteeing the normal clamping function of the clamping mechanism 3. A damping ring 37 fixed inside the rotating groove 36 is rotatably connected to one side of the limiting clamping plate 35 and the holding clamping plate 34, increasing the damping during clamping plate rotation. This makes the clamping plate more stable during rotation, preventing workpiece damage or clamping failure due to excessively fast or unstable rotation, and improving the stability and reliability of the clamping mechanism 3 in clamping workpieces.

[0021] Working Principle: During the rapid workpiece handling process in the automated production line, the moving mechanism 2 begins operation. The motor 23 starts, and its output drives the threaded rod 28 to rotate. Since the moving plate 29 is threaded onto the outside of the threaded rod 28, and the limiting rods 21 on both sides slide against the limiting grooves 24 on both sides of the moving frame 20, the moving plate 29 moves stably horizontally along the limiting rods 21 under the rotation of the threaded rod 28. During the movement of the moving plate 29, the connecting frame 27 on the lower surface moves along with it, and the lifting cylinder 26 on the inner wall of the connecting frame 27 also moves accordingly. When it is necessary to adjust the vertical position of the clamping mechanism 3, the lifting cylinder 26 starts, and its output drives the clamping mechanism 3 to move up and down, thereby adjusting the position of the clamping mechanism 3 in both the horizontal and vertical directions to accurately reach the target workpiece position for clamping.

[0022] Once the clamping mechanism 3 reaches the target workpiece position via the moving mechanism 2, it begins the clamping action. The clamping cylinder 32 is activated, its output driving the rotating rod 33 to move. The lower end of the rotating rod 33 is rotatably connected to one side of the clamping plate 34, causing the clamping plate 34 to rotate within the rotating groove 36, moving closer to and clamping the workpiece. Simultaneously, the limiting clamping plate 35 within the rotating groove 36 provides auxiliary positioning and limiting, preventing the workpiece from shifting or falling during clamping. The damping ring 37 inside the rotating groove 36 is rotatably connected to the limiting clamping plate 35 and one side of the clamping plate 34, increasing damping during clamping rotation and making the clamping action smoother and more precise. After clamping, the clamping mechanism 3 moves with the moving mechanism 2 to the designated position to place the workpiece.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
