The Automated Stator Assembly Line for Motor Manufacturing is designed to minimize labor costs 

and increase production efficiency in motor stator manufacturing. By integrating modular machines and 

robotic transfer systems, this solution ensures a streamlined and precise assembly process that enhances 

productivity and product consistency.

Line Structure and Key Features

1. Modular Line Design: The production line consists of interconnected workstations and standalone

   machines linked by robotic arms and mechanical handlers to automate part transfer and process transition.

2. Independent Control System: Each station features standalone PLC control for flexible, independent

   operation and seamless coordination.

3. Central Line Control: Equipped with an intelligent line control system that manages stop gates, lifts,

   and positioning units for stator handling.

4. Automated Paper Insertion Station: With auto-loading, unloading, and positioning, the slot insulation

   process is fully automated.

5. Yaskawa Robotic Arm Integration: Ensures precise and stable transfer of stators between the paper

   insertion and coil winding/inserting stations.

6. Custom Mechanical Grippers: Used for transfer between shaping and wire binding stations, ensuring

   alignment and process continuity.

7. Dual-Function Binding Machine: Automatically completes both tying and knotting tasks in a single cycle.

8. Automated Testing System: Conducts resistance, hi-pot, and insulation resistance testing, and classifies

   stators into qualified and unqualified groups for downstream processes.
