1、 Origin of assembly line
In 1769, Josiah Wedgwood, an Englishman, opened the Etruscan ceramics factory, where he carried out a fine division of labor. He divided the pottery making process originally completed by one person from the beginning to the end into dozens of special processes, which were completed by specially assigned persons. In this way, the original meaning of "Potter" no longer exists. The only thing that exists is that the potters, such as the diggers, the transporters, the pretenders and the blank makers, have become the workers of the potting workshop. They must work according to the fixed working rhythm and obey the unified labor management.
2、 Advantages of assembly line
1. The assembly line integrates the production process. The assembly line can arrange various stations on the assembly line, and the assembly line can meet the production demand;
2. High expandability of assembly line. Assembly line can be designed according to the needs of the factory;
3. The assembly line can save the production cost of the factory. The assembly line can save the number of production workers to a certain extent. The assembly line can realize the automatic production assembly line to a certain extent. The investment in the early stage is not large and the return rate of the assembly line is high.
3、 Characteristics of pipeline
1. The assembly line is highly specialized.
2. The process of the assembly line is closed. The assembly line is arranged according to the process sequence. The working objects of the assembly line move in one direction among the processes.
3. The processing time of each process of the assembly line is consistent with the proportion of the number of working places of each process.
4. Each process of the assembly line is produced according to the same rhythm. The so-called beat of assembly line refers to the production time interval of two adjacent products.
4、 Pipeline form
1. Pipeline can be divided into fixed pipeline and mobile pipeline according to whether the production object moves or not.
2. The assembly line can be divided into single variety assembly line and multi variety assembly line according to the number of production varieties.
3. According to the continuous degree of production, the assembly line can be divided into continuous assembly line and discontinuous assembly line.
4. According to the way of realizing rhythm, pipeline can be divided into forced rhythm pipeline and free rhythm pipeline.
5. According to the degree of mechanization, the assembly line can be divided into manual, mechanized and automatic assembly lines.
