Automobile body welding production line is one of the important
production lines in the production process of cars, minibuses and
other models. From the perspective of the development history of
the automobile industry, the body welding line has experienced
manual welding lines in the 1950s and 1960s to automated rigid
welding in the 1970s. Assembly line - the stage of robotic flexible
welding assembly line after the 1980s.
Development Trend of Automobile Welding Production Line
At present, the development trend of the world's automobiles is
from mass production to multi-variety and small-batch production.
In order to meet the extensive and diverse needs of automobile
consumers and adapt to the fierce competition in the automobile
market, major automobile manufacturers in the world continue to
shorten the model change Cycle, to speed up the update of vehicle
types, so the modern automobile welding line is gradually becoming
more flexible in function.
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.
