[0016] An assembly method includes the following operating steps:

[0017] S01: The electric bicycle to be assembled is conveyed below the assembly equipment. The visual detection unit operates to detect the position of the handlebar of the electric bicycle. The position of the assembly equipment is adjusted through the adjusting device above the production line, so that the axis center of the rotating shaft of the second motor and the axis center of the handlebar rotating shaft are at the same vertical axis position. Then the visual detection unit operates to detect the angle, position and height of the handlebar, and transmits the detection information to the control system for calculation. Then the control system controls the second motor to drive the rotating bracket to straighten the handlebar;

[0018] S02: After the handlebar is straightened, 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 towards the handlebar. At the same time, the second driving component and the third driving component operate to make the center of the jaws of the jaw component and the handlebar at the same height. At the same time, the fifth motor operates to drive the rotating plate to rotate to adjust the angle of the pneumatic jaw to adapt to the bending angle of the handlebar. The pneumatic jaw is started to clamp the handlebar, and the positioning module resets;

[0019] S03: The visual detection unit operates again to detect the angle and position information of the instrument card slot on the handlebar. The suction cup in the material taking and assembling component sucks the instrument panel on one side of the feeding device. The control system starts the fourth driving component and the fifth driving component to drive the material taking and assembling component to drive the instrument panel to move directly above the position of the instrument card slot;

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

[0021] S05: Finally, the control system drives the cylinder to press down so that the instrument panel is clamped with the instrument card slot to complete the assembly.

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

[0023] 1. Through the coordinated cooperation among various modules and the precise scheduling of the control system during the entire assembly process, automated operations for multiple steps, such as handlebar angle adjustment, handlebar fixation, dashboard material picking, positioning, and installation, are achieved. Compared with the traditional assembly method that relies on manual auxiliary jigs, the time required for manual operation links is significantly reduced, and the overall assembly efficiency is remarkably improved, which can better meet the requirements of large-scale electric vehicle production;

[0024] 2. The positioning module, clamping module, and assembly module in the assembly equipment are all equipped with corresponding drive components (such as screw drive, pulley drive, etc.) and motor control. Each component can quickly and accurately move to the designated position for corresponding operations. For example, the material picking and assembly component can quickly move in the horizontal and vertical directions and accurately reach the corresponding position of the instrument card 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 detection unit set in the positioning module can detect the relevant information of the handlebar position, angle, height, and instrument card slot in real time and transmit the data to the control system. The control system controls each motor and drive component based on this precise data to achieve the precise alignment of the handlebar, the accurate alignment of the clamping module, and the precise installation of the dashboard, effectively avoiding the accuracy problems such as deviation in the installation position and incorrect angle of the dashboard caused by visual judgment and operation skill differences in manual operation, and ensuring the high precision of the assembly;

[0026] 4. The jaw assembly in the clamping module can achieve fine adjustment in multiple angles and dimensions through multiple motors (such as the fifth motor for angle adjustment and the third drive component for vertical position adjustment), enabling it to adapt to handlebars of different shapes and sizes; the material picking and assembly component of the assembly module also has the functions of angle adjustment and multi-directional movement to ensure the perfect fit between the dashboard and the instrument card slot on the handlebar, further improving the accuracy and consistency of the assembly;

[0027] 5. The clamping module firmly clamps the handlebar through a pneumatic jaw with replaceable jaws to ensure that the handlebar does not displace during the assembly of the dashboard, guaranteeing the stability of the assembly reference. 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 downward pressing process of the dashboard installation, it can adapt to the surface of the dashboard, apply pressure evenly, and ensure reliable clamping between the dashboard and the instrument card slot through pressure feedback, reducing the possibility of quality problems such as abnormal display and loose connection of the dashboard during subsequent use and improving the stability of product quality;

[0028] 6. The jaws of the starting jaw are replaceable parts and can be adapted and replaced according to the handlebars of different sizes; the suction cup assembly is also a replaceable design and can be replaced accordingly according to different instrument models. The design of such 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 different specifications and models, improves the versatility of the equipment, and reduces the cost for enterprises to configure a variety of special equipment for different products;

[0029] 7. The entire assembly process is carried out orderly under the coordination of the control system, and the operation 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 enterprises to conduct refined management of the production process and realize operations such as statistical analysis of production data and optimization and improvement of the production process.

[0058] S01: The electric bicycle to be assembled is conveyed below the assembly equipment. The vision detection unit 208 operates to detect the position of the handlebar of the electric bicycle. The position of the assembly equipment is adjusted through the adjusting device above the production line, so that the axis center of the rotating shaft of the second motor 206 and the axis center of the handlebar rotating shaft are at the same vertical axis position. Then the vision detection unit 208 operates to detect the angle, position, and height of the handlebar, and transmits the detection information to the control system for calculation. Then the control system controls the second motor 206 to drive the rotating bracket 207 to straighten the handlebar.

[0059] S02: After the handlebar is straightened, according to the position and height information detected by the vision detection unit 208, the control system drives the third motor 3022 to drive the entire clamping module 30 to move towards the handlebar. At the same time, the second driving component 304 and the third driving component 306 operate to make the center of the jaws of the jaw assembly 305 at the same height as the handlebar. At the same time, the fifth motor 3052 operates to drive the rotating plate 3053 to rotate to adjust the angle of the pneumatic jaw 3054 to adapt to the bending angle of the handlebar. The pneumatic jaw 3054 is started to clamp the handlebar, and the positioning module 20 resets.

[0060] S03: The vision detection unit 208 operates again to detect the angle and position information of the instrument card slot on the handlebar. The suction cup 40553 in the material taking and assembling component 405 sucks the instrument panel on one side of the feeding device. The control system starts the fourth driving component 402 and the fifth driving component 404 to drive the material taking and assembling component 405 to drive the instrument panel to move to directly above the position of the instrument card slot.

[0061] S04: The control system controls the ninth motor 4053 to drive the mounting plate 4052, the cylinder 4054, and the suction cup assembly 4055 to rotate and adjust the angle so that the dashboard angle matches the instrument slot angle.

[0062] S05: Finally, the control system drives the cylinder 4054 to press down so that the dashboard is clamped with the instrument slot to complete the assembly.
