[0025] In combination Figure 2 , Figure 3 and Figure 5As shown, the screw fastening mechanism 5 includes fixed frames 51 symmetrically mounted on both sides of the support plate 2. One side of the fixed frame 51 is provided with a third servo motor 52, and the output end of the third servo motor 52 is fixedly connected with a first movable frame 53. One side of the first movable frame 53 is provided with a fourth servo motor 54, and the output end of the fourth servo motor 54 is fixedly connected with a second movable frame 55. The top of the second movable frame 55 is provided with a fifth servo motor 56, and the output end of the fifth servo motor 56 is fixedly connected with a screw fastening suction head 57. Specifically, the fixed frame 51 is mounted on both sides of the support plate 2 and is symmetrically arranged. It provides a stable support foundation for the entire screw fastening mechanism 5, ensuring that the mechanism will not shake or deviate during operation. One side of each fixed frame 51 is mounted with a third servo motor 52. The output end of the third servo motor 52 is fixedly connected with the first movable frame 53, so that the rotation of the motor can be controlled to drive the first movable frame 53 to move accurately in the horizontal direction. This movement is usually used to adjust the position of the screw fastening suction head in the X-axis direction. The first movable frame 53 is the direct driving object of the third servo motor 52, and the first movable frame 53 can move freely in the horizontal direction. At the same time, it also provides an installation platform for the subsequent fourth servo motor 54 and fifth servo motor 56, so that the entire fastening mechanism can be flexibly adjusted in three-dimensional space. The fourth servo motor 54 is installed on one side of the first movable frame 53, and its output end is fixedly connected with the second movable frame 55. By controlling the rotation of the fourth servo motor 54, the second movable frame 55 can be driven to move accurately in a plane perpendicular to the movement direction of the first movable frame 53 (i.e. Y-axis direction). This movement further increases the flexibility of the screw fastening position. The second movable frame 55 is the direct driving object of the fourth servo motor 54, and the second movable frame 55 not only carries the subsequent fifth servo motor 56 and screw fastening suction head 57, but also can move accurately in the Y-axis direction. It can be more accurately positioned to the screw position that needs to be fastened. The fifth servo motor 56 is installed on the top of the second movable frame 55, and its output end is fixedly connected with the screw fastening suction head 57. By controlling the rotation (or possibly linear motion, depending on the type and connection method of the motor) of the fifth servo motor 56, the screw fastening suction head can be driven to move accurately in the Z-axis direction, i.e. perpendicular to the support plate 2. This movement is usually used to accurately position the screw fastening suction head 57 to the screw head and perform subsequent fastening operations. The screw fastening suction head 57 is the execution component of the entire fastening mechanism, and the screw fastening suction head 57 usually has the functions of adsorbing screws and rotating fastening. Through vacuum adsorption or other means, the screw is firmly adsorbed on the screw fastening suction head 57, and then rotated to fasten the screw to the predetermined position.

[0026] In combination Figure 3 , Figure 3 and Figure 4As shown, the screw fastening suction head 57 includes a pneumatic cylinder 571 mounted on the second movable frame 55, and the output end of the pneumatic cylinder 571 is fixedly mounted with a suction head 572. Specifically, the pneumatic cylinder 571 is a kind of pneumatic actuator that converts the pressure energy of compressed air into mechanical energy. The pneumatic cylinder 571 is mounted on the second movable frame 55 as the main power source for driving the suction head 572. By controlling the pressure change of the gas in the pneumatic cylinder 571, the piston rod of the pneumatic cylinder 571 can be driven to move linearly, thereby driving the suction head 572 to move up and down. The suction head 572 is the part that directly contacts the screw and usually has the functions of adsorbing the screw and rotating and fastening. The suction head 572 is fixedly mounted on the output end of the pneumatic cylinder 571, i.e., the piston rod of the pneumatic cylinder. Therefore, when the pneumatic cylinder 571 works, the suction head 572 will move up and down with the extension and retraction of the piston rod, achieving accurate positioning and fastening operation on the screw. When the screw needs to be fastened, the suction head 572 is first accurately positioned above the screw through the cooperative work of the third servo motor 52, the fourth servo motor 54 and the fifth servo motor 56. Then, the pneumatic cylinder 571 is started to make the suction head 572 descend and tightly adhere to the head of the screw. At this time, the suction head 572 can firmly adsorb the screw through vacuum adsorption or other ways. Next, the suction head 572 can start to rotate and screw into the predetermined position through friction, completing the fastening operation. In addition, since the pneumatic cylinder 571 has the advantages of fast response, accurate control and high reliability, this design can also improve the overall performance and stability of the screw fastening mechanism. At the same time, the use of the pneumatic cylinder 571 also simplifies the structure of the mechanism, reduces the manufacturing cost and maintenance difficulty.

[0027] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , the support plate 2 is provided with a start switch 6. Specifically, the start switch 6 can be a button, a knob or a touch switch, which is arranged on the support plate 2 for intuitive and convenient operation by the operator in front of the equipment. When the operator needs to start the equipment to work, he / she only needs to press or rotate the start switch 6, and the control system inside the equipment will receive the corresponding signal and start each component such as the servo motor, the pneumatic cylinder, etc. in turn, so that the equipment enters the working state. At the same time, the start switch 6 can also have multiple functions, such as an emergency stop button and a reset button. The emergency stop button is used to quickly cut off the power supply of the equipment in emergency situations to avoid accidents; the reset button is used to restore the equipment to the initial state after the equipment fails or abnormally stops, so as to restart.

[0028] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the cabinet body 1 is provided with a distribution box 7. Specifically, the cabinet body 1 is provided with a distribution box 7 as the center of power distribution and control, which plays a crucial role in the normal operation of the entire device or institution. The distribution box 7 usually contains a plurality of circuit elements such as circuit breakers, contactors, fuses, etc. inside, which are used to distribute electrical energy from external power sources to various parts of the device or institution. These circuit elements can supply electrical energy with appropriate voltage, current and frequency to various motor, cylinder, sensor, etc. execution elements and control elements according to the needs of the device. In addition to power distribution, the distribution box 7 also undertakes the task of power control. It can control the start-stop, speed regulation, direction control, etc. of various parts of the device or institution through internal circuit logic or external control signals. This power control function enables the device or institution to work according to the predetermined program and parameter, thereby realizing automation and intelligence. The distribution box 7 also has the function of safety protection. It can monitor and protect the circuits and elements in the device or institution in real time through internal protection devices such as overload protection, short circuit protection, leakage protection, etc. Once abnormal conditions such as excessive current, high voltage, insulation damage, etc. are detected, the distribution box 7 will immediately cut off the power or issue an alarm signal to prevent accidents such as device damage or personnel injury. The design of the distribution box 7 usually takes into account the needs of easy maintenance and repair. It uses detachable panels and wiring terminals, so that maintenance personnel can easily open the door to check, repair and replace the internal circuits and elements. In addition, the distribution box 7 is also equipped with clear identification and instructions, so that maintenance personnel can quickly and accurately find the fault point and handle it.

[0029] In combination with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the cabinet body 1 is provided with a control system 8 on one side. Specifically, the cabinet body 1 is provided with a control system 8 on one side, which has high requirements for centralized control, efficient operation and safety protection. The control unit of the control system 8 is responsible for receiving and processing signals from various sensors, buttons and other input devices, and issuing control instructions to the actuator (such as motor, cylinder, etc.) according to the preset program or algorithm. The control system 8 provided on one side of the cabinet body 1 is an indispensable important part of modern industrial equipment. The control system 8 provides strong support for the normal operation of the device or system through the functions of centralized control, automated operation, real-time monitoring, safety protection and easy maintenance, etc.
