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.
