[0002] In numerous industrial and scientific research fields, the demand for precise adjustment of the position and orientation of objects is increasing. For example, in industrial automated production lines, the high-precision assembly of parts requires mechanisms that can flexibly adjust angles and positions to adapt to the production requirements of different products.

[0003] Currently, common adjustment mechanisms on the market have many limitations. Some traditional multi-degree-of-freedom adjustment mechanisms often have a limited number of degrees of freedom, making it impossible to meet the demand for omnidirectional adjustment in complex working conditions. For example, the common six-degree-of-freedom robotic arm, in certain special scenarios, struggles to achieve precise control of target objects due to the lack of additional rotational or translational degrees of freedom. Furthermore, existing adjustment mechanisms also lack precision, failing to meet the levels required for some high-precision applications. Moreover, most traditional mechanisms have low levels of intelligence, requiring frequent manual intervention for parameter setting and operational adjustments, resulting in low work efficiency and failing to adapt to the development trends of modern automated production and intelligent control.

[0024] As shown in the attached figure, a seven-degree-of-freedom intelligent adjustment mechanism includes a liftable support arm 1 and a lifting platform 2 located at the top of the support arm 1. The support arm 1 includes a support arm base 3, a lifting cylinder 4, a telescopic cylinder (not shown), and a telescopic support arm 5. The bottom end of the telescopic support arm 5 is connected to the support arm base 3. The bottom end of the lifting cylinder 4 is hinged to the support arm base 3, and the piston end is hinged to the side of the telescopic support arm 5. The telescopic cylinder is located inside the telescopic support arm 5 and pushes the telescopic support arm 5 to extend and retract. The lifting platform 2 includes an XYZ adjustment bracket and a rotary drive mechanism 6. The rotary drive mechanism 6 is mounted on the XYZ adjustment bracket and includes a rotating seat 7, a rotating arm 8 rotatably connected to the rotating seat 7, and a motor 9 that drives the rotating arm 8 to rotate. The output shaft of the motor 9 is connected to the rotating arm 8 through a gear transmission device. When the motor is running, the rotating arm 8 is driven to rotate through the meshing transmission between the gears.

[0025] The XYZ adjustment bracket includes an X-axis guide structure 10, a Y-axis guide structure 11, a Z-axis guide structure 12, and a pitch structure 13. The X-axis guide structure 10 is located at the top of the support arm 1. The pitch structure 13 includes a mounting bracket 14, a pitch cylinder 15, a pitch base plate 18, and a photoelectric sensor 19. The mounting bracket 14 includes a bottom bracket 16 and an upper bracket 17. The bottom bracket 16 is mounted on the slider of the X-axis guide structure 10, and the upper bracket 17 is hinged above the bottom bracket 16. The bottom end and piston end of the pitch cylinder 15 are respectively hinged to the side of the bottom bracket 16 and the side of the upper bracket 17. The pitch base plate 18 is set on the upper bracket 17, the photoelectric sensor 19 is set on the pitch base plate 18, the Y-direction guide structure 11 is set on the upper bracket 17, the Z-direction guide structure 12 is set on the Y-direction guide structure 11, and the rotary drive mechanism 6 is set on the Z-direction guide structure 12. In this case, the Z-direction guide structure 12 is raised and lowered by the rotary drive mechanism 6 driven by the cylinder.

[0026] The X-direction guide structure 10 and the Y-direction guide structure 11 have the same structure, both including a base plate 20, a guide rail 21, a slider 22, and a hydraulic cylinder 23.

[0027] Drive System: The drive system provides power to the entire mechanism, and each joint's drive motor is a high-precision servo motor. Servo motors are characterized by fast response speed and high control precision, enabling precise control of the joint's movement speed and position. Simultaneously, a high-precision encoder is installed between the motor output shaft and the transmission device to monitor the motor's rotation angle in real time and feed the signal back to the intelligent control system, allowing the system to perform precise closed-loop control of the motor's movement.

[0028] Intelligent Control System: The intelligent control system is the core component of this mechanism, based on advanced microprocessors and control algorithms. The system acquires real-time status information such as the position, velocity, and acceleration of each joint through sensors, as well as relevant data from the external environment (e.g., the position information of the target object obtained by a vision sensor). Based on preset control commands and algorithms, the intelligent control system precisely controls the servo motors in the drive system, enabling coordinated movement of the mechanism in seven degrees of freedom to achieve precise position and posture adjustment of the target object. For example, in industrial assembly scenarios, the system can automatically calculate the required movement parameters of each joint based on the component position information fed back by the vision sensor. The control mechanism then precisely moves the assembly tool to the designated position and adjusts it to the appropriate posture to complete the assembly of the components.
