As one of the four major processes in the automotive industry, the
welding process is self-evident. It shoulders the important mission
of forming the body and providing a supporting frame for the
vehicle. In addition to ensuring the appearance and shape, it must
also ensure that all parts of the final assembly The precision of
the component installation point, so its process is far more
complicated than the other three major processes. The planning and
layout of the production line not only need to consider from the
aspects of precision assurance, production efficiency, distribution
logistics, and storage, but are also limited by the plant area and
structure, Existing conditions such as painting corridors. There is
no perfect layout plan, only the most suitable layout plan at
present.
6. Logistics and warehousing planning
Logistics warehousing planning should be considered comprehensively
in combination with process layout and production tempo, and should
roughly follow the following principles:
(1) The size of the storage area should meet the basic inventory
requirements. The basic inventory is generally not less than 2
hours of consumption. The area of the storage area should be
calculated based on the total number of parts, the size of the
parts station and equipment, and the number of frames to ensure
that the area is not less than the area required for 2 hours of
inventory.
(2) The storage area should be close to the logistics door of the
workshop and the logistics channel of the factory area.
(3) In consideration of logistics efficiency and space saving, the
width of logistics channels between welding lines is generally
about 3m.
(4) Logistics channels must be reserved for all workstations that
need to be loaded to ensure distribution space.
(5) The logistics direction cannot be opposite to the overall flow
direction of the body.
