When the clamping force reaches the preset value, the control system automatically stops the fifth motor 34 to avoid damage to the logistics box due to excessive clamping force, and to prevent the logistics box from falling due to insufficient clamping force, thereby ensuring safety and stability during the transportation of the logistics box.

[0013] Embodiment three: See also Figure 10, and on the basis of the first and second embodiments, it is further obtained that the moving mechanism 4 includes a support base 41, the support base 41 is fixedly connected to the top of the base 1, support legs 42 are fixedly connected to the four corners of the support base 41, placing plates 44 are fixedly connected to both sides of the support base 41, cylinders are fixedly connected to the bottoms of the placing plates 44, and walking wheels are fixedly connected to the bottoms of the cylinders. The walking wheels are made of high-strength polyurethane material, having good wear resistance and anti-slip performance. When the walking wheels contact the ground, the robotic arm can drive the walking wheels to rotate through the built-in drive motor, realizing the movement of the robotic arm. At the same time, the robotic arm is equipped with a laser navigation system and ultrasonic sensors, which can sense the surrounding environment in real time, automatically plan the moving path, avoid obstacles, reduce the limitations in position, enabling it to move freely in complex environments such as logistics warehouses and production workshops, greatly improving the work efficiency; Working principle: In the modern industrial and logistics fields, the application of precision robotic arms is becoming increasingly widespread. This robotic arm demonstrates excellent performance with its powerful and precise angle adjustment, accurate clamping, and flexible movement functions; In terms of angle adjustment, its design is delicate and versatile. When it is necessary to adjust the angle of the support arm 209 of the robotic arm, the fourth motor 2015 can be started. The fourth motor 2015 is a high-precision servo motor, with the characteristics of high torque and low speed, and can provide stable and strong power for subsequent transmission. It is connected to the fifth spur gear 2013 and the fourth spur gear 2012 through a high-precision transmission shaft. Using the principle of gear transmission, it can drive the fifth spur gear 2013 and the fourth spur gear 2012 to rotate synchronously. During the gear rotation process, through a series of precise link mechanisms, the rotational motion of the gears is converted into the angle change of the support arm 209, thereby realizing the precise adjustment of the angle of the support arm 209. This adjustment process adopts a closed-loop control system, and the angle sensor real-time feedbacks the angle of the support arm 209 to ensure that the adjustment accuracy reaches ±0.1°, meeting the requirements for the angle of the support arm 209 under various complex working conditions; When it is necessary to rotate the first clamp 31 and the second clamp 32, the first motor 21 can be started. The first motor 21 is also a high-performance servo motor. Its unique dual-axis output design can drive the two second spur gears 203 to rotate synchronously at the same time. These two second spur gears 203 are respectively meshed with the toothed rings on the rotating member 26. Through gear transmission, the rotating member 26 is driven to rotate 360° without dead angles. The rotation of the rotating member 26 drives the first clamp 31 and the second clamp 32 to rotate accordingly. During the rotation process, the equipped encoder can real-time monitor the rotation angle and speed, and cooperate with the control system to achieve precise positioning and speed control, enabling the first clamp 31 and the second clamp 32 to quickly and accurately reach the specified angle, meeting the requirements for high-precision operations; To adjust the overall angle of the robotic arm, start the fourth motor 2015 again. At this time, the fourth motor 2015 not only drives the fourth spur gear 2012 and the fifth spur gear 2013 to rotate synchronously, but also is connected to the toothed ring 208 through a transmission chain. The toothed ring 208 is fixed on the base 1 of the robotic arm. When the fourth motor 2015 drives the gears to rotate, the transmission chain transmits the power to the toothed ring 208, causing the toothed ring 208 to rotate. The rotation of the toothed ring 208 drives the rotating rod connected to it to rotate synchronously. The rotating rod is the main support structure of the robotic arm, and its rotation realizes the angle adjustment of the overall robotic arm in the horizontal and vertical directions. The entire adjustment process is buffered and shock-absorbed by a hydraulic damping system, effectively reducing the vibration and impact during the rotation process, and ensuring the stability and reliability of the overall robotic arm; For the adjustment of the angle between the first fixture 31 and the second fixture 32, the second motor 25 needs to be started. The second motor 25 drives the worm to rotate. The worm meshes with the worm gear 23. Using the speed reduction and torque increase characteristics of the worm gear 23 worm mechanism, the high-speed rotation of the motor is converted into the low-speed and high-torque rotation of the worm gear 23. The rotation of the worm gear 23 forms a linkage through a pulley group. The pulley group uses a high-precision synchronous belt, which can ensure the accuracy and stability of the transmission. The pulley group transmits the power to the placement shaft and the output shaft. The placement shaft and the output shaft are respectively connected to the first fixture 31 and the second fixture 32, and the flexible adjustment of the angle between the first fixture 31 and the second fixture 32 is realized through their rotation. This adjustment system can realize an angle change of 0 - 180°, and the adjustment accuracy can reach ±0.5°, which can meet the grasping and placement requirements of items with different shapes and sizes; In terms of the clamping function of the logistics box, the robotic arm also performs excellently. When it is necessary to clamp the logistics box, start the fifth motor 34. The fifth motor 34 is a high-response stepper motor that can quickly and accurately respond to control signals. It is connected to the sixth spur gear 37 through a transmission shaft and drives the sixth spur gear 37 to rotate synchronously. The sixth spur gear 37 meshes with the rack on the arc-shaped toothed plate 36. When the sixth spur gear 37 rotates, it can drive the arc-shaped toothed plate 36 to move linearly. At the same time, the arc-shaped toothed plate 36 is connected to the half gear 33 through a linkage mechanism, causing the half gear 33 to move in the opposite direction. The half gear 33 meshes with the racks on the first fixture 31 and the second fixture 32. The movement of the half gear 33 drives the first fixture 31 and the second fixture 32 to move towards each other, thereby realizing the clamping and fixing of the logistics box. During the clamping process, the pressure sensor continuously monitors the clamping force. When the clamping force reaches the preset value, the control system automatically stops the fifth motor 34, avoiding damage to the logistics box due to excessive clamping force and preventing the logistics box from falling due to insufficient clamping force, ensuring the safety and stability during the transfer of the logistics box; In terms of the overall movement of the robotic arm, its design is equally ingenious. When the overall movement of the robotic arm is required, the second cylinder 43 is activated. The second cylinder 43 is a double-acting cylinder, which has the characteristics of large thrust and fast response. The piston rod of the second cylinder 43 is connected to the walking wheel bracket. When the second cylinder 43 is activated, the piston rod extends, driving the walking wheel to move downward. The walking wheel is made of high-strength polyurethane material, which has good wear resistance and anti-slip properties. When the walking wheel contacts the ground, the robotic arm can drive the walking wheel to rotate through the built-in drive motor to achieve the movement of the robotic arm. At the same time, the robotic arm is equipped with a laser navigation system and ultrasonic sensors, which can sense the surrounding environment in real time, automatically plan the movement path, avoid obstacles, reduce the limitations in position, enable it to move freely in complex environments such as logistics warehouses and production workshops, and greatly improve work efficiency and flexibility; By comprehensively and precisely adjusting the angles of various parts of the robotic arm, and achieving precise clamping of the logistics box and flexible overall movement, this precise mechanical system can play a powerful role in various fields such as logistics and intelligent manufacturing. In the logistics field, whether it is quickly and accurately storing and retrieving goods of different specifications and positions in an automated warehouse, or efficiently sorting a large number of packages in a courier sorting center, it can complete the work efficiently and precisely with its flexible angle adjustment function and precise clamping ability. In the field of intelligent manufacturing, it can be applied to complex assembly tasks, such as the assembly of automotive parts and the precision assembly of electronic products. With high-precision operating performance, it ensures product quality and production efficiency, demonstrating excellent performance and reliability.
