According to the difference of manufacturing industry and technology, automatic production line has many types, such as automatic machining production line, automatic assembly production line, automatic spraying production line, automatic welding production line, automatic electroplating production line, etc. There are two typical types: one is automatic machining production line, which is used in mechanical parts processing industry; the other is automatic assembly production line, which is used in the later assembly production of various products.

Automatic production line is mainly engaged in parts milling, drilling and other similar rotary cutting process. In the automatic production line, according to the difference of production line structure, it can be divided into the following two types: the automatic production line without internal parts storage buffer and the automatic production line with internal parts storage buffer.
