1. The production process of fixed production or a few kinds of products (parts) on the automated assembly line is continuous, and the automated assembly line should be continuous to greatly improve production efficiency.

2. Each station on the automated assembly line is arranged in the order of the product process. Each station is only fixed to complete a few or a few processes, with a high degree of specialization, and the use of automated assembly lines is more advanced to improve production efficiency;

3. The automated assembly line is produced in accordance with the beat of the system (the so-called beat is the time interval between the production of two identical products before and after the assembly line);

4. The production capacity of each station on the automated assembly line is balanced and proportional, and the single processing time of each process is equal to the beat or multiple of the beat;

5. The automated assembly line is equipped with a special conveying device, and the products move according to a one-way transportation route.
