The characteristics of the automatic production line are as follows:
1. One or a few kinds of products (parts) are fixedly produced on the production line, and the production process is continuous;
2. Each workplace on the production line is arranged in the order of the production process. Only one or a few processes are fixed in each workplace, and the degree of specialization is high;
3. The production line is produced according to a unified rhythm (the so-called rhythm is the time interval between the production of two identical products before and after the assembly line);
4. The production capacity of each work site on the production line is balanced and proportional, and the single-piece processing time of each process is equal to the beat or a multiple of the beat;
5. The production line is equipped with a special conveying device, and the products move according to the one-way transportation route.
Products produced by automated production lines should have a sufficiently large output; product design and the process should be stable, reliable, and remain basically unchanged for a long time. The use of automatic lines in mass and mass production can improve labor productivity, stabilize and improve product quality, improve labor conditions, reduce production area, reduce production costs, shorten production cycles, ensure production balance, and have significant economic benefits.
The automatic production line is the process of automatic operation or control according to the prescribed procedures or instructions without human intervention, and its goal is "stable, accurate and fast". Automation technology is widely used in industry, agriculture, military, scientific research, transportation, commerce, medical care, services, and households. The use of automated production lines can not only liberate people from heavy manual labor, part of mental labor, and harsh and dangerous working environments, but also expand human organ functions, greatly improve labor productivity, and enhance human ability to understand the world and transform the world.
