1.Overall scheme design of automated production line 

When designing an automated production line, it is necessary to consider not only the realization of the product assembly process and meeting the required production rhythm, but also the connection between the conveying system and each dedicated machine and robot of the automated production line in terms of structure and control. Through process and rhythm optimization, the structure of the production line should be simple and efficient, achieving a high cost-performance ratio. Therefore, the quality of the overall scheme design is of vital importance and should be carried out on the basis of a thorough study of the product assembly process flow. 

• Requirements for the product's structure, usage functions and performance, assembly process, workpiece orientation and direction, and workpiece handling. Conduct in-depth research on the production techniques, process flow, required production rhythm, and site requirements for the production line layout, and adjust the original process flow of the product if necessary. 

• Determine the sequence of each process, the processing methods, the cycle time of each work station, the occupied space dimensions of each work station, the conveying line mode and its main dimensions, the separation and stopping of workpieces on the conveying line, the reversing and repositioning of workpieces, etc. 

2.Review of the Overall Design Scheme for the Automated Production Line 

Organize experts to review the overall design plan of the automated production line, identify possible flaws or errors in the overall design plan, and avoid causing greater losses. 

3. Detailed design of the automated production line 

After the overall plan for the automated production line design is determined, detailed design can be carried out. The detailed design stage includes mechanical structure design and electrical control system design. 

①Mechanical structure design of automated production lines 

The detailed design stage involves time-consuming and labor-intensive work, mainly mechanical structure design, including the design of each dedicated machine structure and the conveying system. The design drawings include assembly drawings, component drawings, part drawings, pneumatic circuit diagrams, pneumatic system action sequence diagrams, standard parts list, purchased parts list, and machined parts list, etc. 

Due to the highly specialized industrial division of labor in the automatic machinery industry, in mechanical structure design, it is usually not the case that all structures are designed and manufactured in-house. For instance, conveyor lines are often outsourced as a whole to enterprises specializing in their production for design and manufacturing. Specialized equipment such as robots are also directly ordered from professional manufacturers and then integrated into the system. This approach can fully leverage the core advantages and competitiveness of the enterprise. In this sense, the design of an automated production line is actually a systematic integration work of various process technologies and equipment products, with the core technology being system integration technology. It is evident that the overall scheme design plays a crucial role in the process of automatic machinery design and manufacturing. 

②Design of Electrical Control System for Automated Production Lines 

The main tasks of the electrical control system design for an automated production line include: based on the working process and requirements of the mechanical structure, designing the distribution plan of various sensors for detecting workpieces or mechanisms, electrical schematic diagrams, wiring diagrams, input and output signal address allocation diagrams, PLC control programs, and the list of purchased electrical components and materials. The control system designer must fully understand the design intentions of the mechanical structure designer and have a detailed understanding of the working process of the controlled object. 

4.Review of design drawings for automated production lines 

After the detailed design of the automated production line is completed, it is necessary to organize experts to review the detailed design plan and drawings. Any defects and errors found should be promptly corrected and improved. 

5. Ordering of dedicated equipment and components, and processing and manufacturing of machined parts 

Due to the highly specialized division of labor in the current industry, in the automatic machinery industry, a large number of specialized equipment, components and structural parts have been specifically manufactured and produced by related enterprises. After the design stage is completed, the ordering of various specialized equipment and components and the processing and manufacturing of machine parts will be carried out simultaneously. 

As basic component manufacturers have gradually moved their factories closer to market areas, many foreign component manufacturers have successively set up production plants in China. As a result, the ordering cycle for automatic mechanical components has gradually shortened, facilitating automatic machinery manufacturing enterprises to further reduce their manufacturing cycle.
