[0018] S02: After the handlebar is aligned, according to the position and height information detected by the visual detection unit, the control system drives the third motor to drive the entire clamping module to move toward the handlebar, and at the same time, the second drive assembly and the third drive assembly operate so that the center of the clamping jaw of the clamping jaw assembly is at the same height as the handlebar, and at the same time, the fifth motor operates to drive the rotating plate to rotate, so as to adjust the angle of the pneumatic clamping jaw to adapt to the bending angle of the handlebar, start the pneumatic clamping jaw to clamp the handlebar, and reset the positioning module;

[0020] S04: the control system controls the ninth motor to drive the mounting plate, the cylinder and the suction cup assembly to rotate and adjust the angle so that the angle of the instrument panel matches the angle of the instrument slot;

[0021] S05: Finally, the control system drives the cylinder to press down, so that the instrument panel and the instrument slot are engaged to complete the assembly.

[0022] Beneficial effects: The invention has reasonable design, simple and stable structure, strong practicability, and has the following beneficial effects:

[0023] 1. The entire assembly process realizes the automated operation of multiple steps, from handlebar angle adjustment and fixation to instrument panel material collection, positioning, and installation, through the coordinated cooperation among various modules and the precise scheduling of the control system. Compared with the traditional assembly method that relies on manual auxiliary fixtures, it greatly reduces the time required for manual operation, significantly improves the overall efficiency of assembly, and can better meet the needs of large-scale production of electric vehicles;

[0024] 2. The positioning module, clamping module and assembly module in the assembly equipment are equipped with corresponding drive components (such as screw drive, pulley drive, etc.) and motor control. Each component can be quickly and accurately moved to the specified position for corresponding operations. For example, the material picking assembly component can move quickly in the horizontal and vertical directions and accurately reach the corresponding position of the instrument slot on the handlebar, effectively shortening the waiting and adjustment time during the assembly process, and further improving the overall assembly efficiency;

[0025] 3. The visual inspection unit set in the positioning module can detect the handlebar position, angle, height and related information of the instrument slot in real time, and transmit the data to the control system. The control system controls each motor and drive component based on these precise data to achieve accurate alignment of the handlebar, accurate alignment of the clamping module and accurate installation of the instrument panel, effectively avoiding the accuracy problems such as instrument panel installation position deviation and angle misalignment caused by naked eye judgment and operating skills differences in manual operation, ensuring high assembly accuracy;

[0026] 4. The gripper assembly in the gripping module can achieve multi-angle and multi-dimensional fine adjustment through multiple motors (such as the fifth motor to adjust the angle, the third drive assembly to adjust the vertical position, etc.), so that it can adapt to handlebars of different shapes and sizes; the material picking assembly assembly of the assembly module also has angle adjustment and multi-directional movement functions to ensure the perfect fit between the instrument panel and the instrument slot on the handlebar, further improving the accuracy and consistency of assembly;

[0027] 5. The clamping module firmly clamps the handlebars with replaceable pneumatic clamps to ensure that the handlebars will not be displaced during the assembly of the instrument panel, thus ensuring the stability of the assembly benchmark. At the same time, the suction cup assembly of the assembly module adopts a design with a spring buffer structure and a pressure sensor. During the installation and pressing process of the instrument panel, it can adapt to the surface of the instrument panel and apply pressure evenly. It also ensures reliable connection between the instrument panel and the instrument slot through pressure feedback, reducing the possibility of quality problems such as abnormal display and loose connection of the instrument panel during subsequent use, thus improving the stability of product quality.

[0028] 6. The clamping jaws of the starter jaws are replaceable parts, which can be adapted and replaced according to handlebars of different sizes; the suction cup assembly is also designed to be replaceable, and can be replaced accordingly according to different instrument models. This design of replaceable parts enables the assembly equipment of the present invention to be applicable to the assembly of electric vehicle instrument panels and handlebars of various specifications and models, thereby improving the versatility of the equipment and reducing the cost of enterprises to configure multiple special equipment for different product needs;

[0029] 7. The entire assembly process is carried out in an orderly manner under the coordination of the control system. The operating parameters in each link (such as the rotation angle of the motor, the position information of each component, the data of the pressure sensor, etc.) can be digitally recorded and stored, which is convenient for the enterprise to carry out refined management of the production process and realize statistical analysis of production data, optimization and improvement of production processes and other operations.
