On the truck assembly line, every part is "finding" its place

Flexible production line architecture Contemporary truck assembly lines generally adopt modular island layout design, breaking the linear constraints of traditional assembly lines. Taking body welding as an example, sub-assemblies such as the top cover, front wall, side wall, and doors are completed by robot clusters in an independent "assembly island" and then accurately transferred to the assembly island through the aerial EMS (Electric Monorail Transport System) for assembly. This architecture makes the production line highly flexible and can be compatible with the mixed-line production of more than 600 different vehicle models, realizing seamless switching between pure trams, hybrid cars, and fuel vehicles. The main body of the assembly line usually adopts a "U"-shaped or "E"-shaped layout, and an AGV (Automatic Guided Transport Vehicle) constitutes a flexible conveying system. Different from traditional fixed chain lines, AGV cars can independently navigate and accurately park according to production instructions, and the station spacing and beat time can be dynamically adjusted. In advanced factories such as Dongfeng Commercial Vehicles, more than 200 AGVs work together with robots, and an average of one light truck...
