[0002] In the motor manufacturing process, the motor rear end cover is one of the key components, and its processing quality directly affects the overall performance and service life of the motor. At present, the stamping process of most motor rear end covers still relies on manual operation, which is specifically manifested as follows: workers need to manually place the rear end cover on the stamping station, and manually rotate it by 90° or flip it after stamping is completed, so as to complete processing in different directions. This method has the following main problems:

[0003] Firstly, manual operation has high safety risks. In stamping operations, workers need to frequently contact the stamping machine and the rear end cover, and if the operation is improper or the equipment is abnormal, safety accidents such as pinching and impact are likely to occur, especially when the workers are tired or distracted, which further increases the risk.

[0004] Secondly, manual direction changing is inefficient. Since different specifications of motor rear end covers need to be adjusted multiple times to complete stamping, this adjustment process is time-consuming and prone to errors, which not only affects the production rhythm, but also may lead to reduced processing precision of the workpiece. In addition, the existing tooling needs to be frequently replaced or adjusted according to the size of the rear end cover, and the process of replacing the tooling further increases the production time and reduces the production efficiency.

[0005] Finally, the existing processing method requires high skills of the operators. Since the process relies on manual operation, workers need to have strong processing experience and operation ability to ensure the quality of the products, which poses great challenges to production organization and training management, and is difficult to meet the needs of modern large-scale and automated production.
