Electric Drive Assembly Line

　　The electric drive assembly line achieves automation, digitalization, and standardization across the entire new‑energy three‑electric‑system assembly process, covering all operations from stator–rotor assembly to final output. Core processes include stator–rotor assembly, gear‑shaft press‑fitting, housing shim selection and measurement, housing bolt tightening, and transfer‑line marking. Stator–rotor assembly employs in‑line pressing with a quick‑change die design, coupled with automatic workpiece rotation, enabling full‑process traceability of pressing data; gear‑shaft press‑fitting likewise supports in‑line pressing and quick‑change dies, with data traceability. Housing shim selection and measurement utilizes online measurement and automated workpiece rotation to ensure precise shim selection; housing bolt tightening is performed by robots, supporting variable‑torque tightening and data traceability; and transfer‑line marking is carried out by robotic pick‑and‑place followed by slide‑table marking, guaranteeing clear, traceable identification.
