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.
