In a narrow sense, the flexible production line generally refers to the mixed production of various models. Various models can adjust the proportion of the entire model arbitrarily according to changes in market demand and under the premise that the total output remains unchanged. Various flexible transmission devices such as elliptical ground circular lines and elevated upper and lower circular lines (as shown in Figure 9) have appeared successively. For example: the T100S/FINR ASSYLINE of Daewoo Motor Corporation of South Korea is to produce the car bodies of three different models of T-100, 3-door, 4-door and 5-door, in mixed flow on the same transmission line.

In the initial stage of automobile development, straight-through production lines (simplified through-type production lines) were mainly used. In the 1960s and 1970s, accompanying fixture production lines were used more often, but due to the large size, complex structure and large motion inertia of the accompanying fixtures , It is difficult to realize the shortcomings of multi-variety production and the supporting use of robots. Therefore, in the middle and late 1970s, major automobile manufacturers improved the through-type production lines. The through-type production line means that the positioning and clamping device (fixture) of the workpiece is separated from the transmission device between the stations. Lifting support rod reciprocating welding line is a commonly used through-type production line. This production line mainly includes the following parts: workpiece clamping and positioning system, transmission device between stations and conveying rod lifting system.
