[0002] In the field of engine manufacturing, due to its special design and working principle, the extended-range engine often requires specific tooling to assist in the assembly process. After assembly, these tooling needs to be disassembled at the next station for recycling. However, on traditional production lines, there is a certain distance between the assembly station and the disassembly station, and workers are usually required to frequently travel back and forth between the two stations to recycle and retrieve the tooling. This frequent round-trip action not only increases the workload of the workers, but also leads to a significant reduction in production efficiency. During each round trip, the workers need to spend time and energy walking and looking for tooling, which is not directly used for the assembly of the engine, so it can be regarded as invalid labor.
