1.Assembly line structure and layout

• Modular design: Both the electric bicycle assembly line and the electric vehicle assembly line usually adopt modular design, which can be flexibly adjusted according to the production demand. For example, Guangliang's customized electric vehicle assembly line supports the customization of length, width and height, and the material can be selected from aluminum profile, stainless steel, etc., to adapt to the assembly requirements of different models. Whether it's a two wheeled electric bicycle assembly line or a more comprehensive electric vehicle assembly line, this modular approach ensures adaptability.

• Bilateral working table design: Some assembly lines, especially for two wheeled electric vehicle automatic assembly line and other types, adopt bilateral working table structure to effectively utilize space and improve production efficiency. For example, the bilateral workbench assembly line realizes anti-static effect through the belt line structure, and the workbench table can be independent or combined for easy adjustment. This design is highly beneficial for streamlining the assembly process of various electric vehicles, from simple electric bicycles to more complex electric vehicle models.

2.Key process

• Frame assembly: The frame is the basic structure of the electric vehicle, whether it's on an electric bicycle assembly line or an electric vehicle assembly line. The assembly process needs to ensure the fastening and positioning accuracy of each component. For example, when installing the limit plate on a two wheeled electric bicycle assembly line, it is necessary to adjust the distance through the adjusting rod and nut to ensure the stability of the installation. This process is crucial for maintaining the structural integrity of different electric vehicle types.

• Installation of motor and controller: Motor and controller are the core components of the electric vehicle. During installation on an electric vehicle assembly line or a two wheeled electric vehicle automatic assembly line, attention should be paid to the line connection and interface matching. For example, the motor line needs to be connected with the controller color correspondingly, and the wiring steps of the controller include the motor line, power line, learning line and so on. Precise installation of these components is essential for the proper functioning of all electric vehicles.

• Electrical system connection: The electrical system involves the connection of power cable, electric door lock cable, turnbuckle cable, brake cable, etc. on various assembly lines like electric bicycle assembly line, electric vehicle assembly line, etc. It is necessary to ensure that the positive and negative poles are correctly connected to avoid short-circuiting or functional failure. For example, the selection of high level brake line and low level brake line depends on the brake voltage. This accurate connection is vital for the safe operation of electric vehicles produced on these assembly lines.

3.Intelligent management

• MES system application: Some factories adopt MES (Manufacturing Execution System) on their electric vehicle assembly line and two wheeled electric vehicle automatic assembly line to realize whole process monitoring and digital management. For example, Nine's Changzhou factory codes and traces key parts through the MES system to realize the intelligent management of one machine, one file, and ensure the traceability of product quality. This system implementation enhances the efficiency and quality control of the assembly process across different electric vehicle types.

• AGV Intelligent Handling: The automated assembly lines, including those for two wheeled electric vehicle automatic assembly line and other electric vehicle assembly lines, introduce AGV (Automatic Guided Vehicle) to realize efficient material handling. This automation significantly improves the overall production flow.

4.Production efficiency and quality control

• High-efficiency production beat: The two wheeled electric bicycle assembly line, whether it's an electric bicycle assembly line or an electric vehicle assembly line, realize high-efficiency production by optimizing the process flow and equipment configuration. This optimization ensures that production meets the demands for different electric vehicle models.

• Strict quality inspection: Multiple quality inspection links are set up during the production process on all types of assembly lines, such as two wheeled electric bicycle assembly line and two wheeled electric vehicle automatic assembly line, to ensure that the products meet the standards. These inspections guarantee the reliability and safety of the final electric vehicle products.
