The air-conditioning production line is an operation line that is equipped with a mechanical system of operators or industrial robots according to the needs of air-conditioning production, and completes the set air-conditioning production process in sequence. It mainly includes five parts: material selection, assembly, leak detection, quantitative fluoridation, and packaging.

Since the 1920s, with the development of industries such as automobiles, rolling bearings, small motors and sewing machines, automatic threads have begun to appear in machinery manufacturing, and the earliest one is the automatic thread of combined machine tools. Prior to this, assembly lines and semi-automatic production lines first appeared in the automotive industry, and then developed into automatic lines. After World War II, there was a sharp increase in the number of automatic lines in machinery manufacturing in industrially developed countries.

Products produced by automatic lines should have a large enough output; product design and technology should be advanced, stable and 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 purpose of air conditioning is to provide a healthy and comfortable artificial environment for people's life, work and entertainment activities. Although the development of modern room air conditioner technology has a history of more than 40 years, it has matured in terms of high efficiency, low noise, miniaturization and high reliability of air conditioners and refrigerators. With the development of automation and balance of air-conditioning production lines, air-conditioning production is also developing towards high efficiency and high performance.
