[0002] In the technical field of stator coil installation production equipment, as the demand for industrial automation continues to rise, the installation production efficiency and quality of stator coils are increasingly concerned. Efficient stator coil installation technology can greatly improve the production scale and quality of related products such as motors, which is of great significance to the development of the entire motor industry and even many industries relying on motor drive. Good stator coil installation method helps to improve the performance stability of motors and reduce the probability of failure, thereby ensuring the normal operation of various mechanical equipment. At the same time, improving production efficiency can effectively reduce production cost and enhance the competitiveness of enterprises in the market. At present, in the field of stator coil installation production, the traditional manual operation method is mainly used in related technologies. Usually, the stator coil is placed on a fixed-position workbench, and a worker completes the full set of process installation of the stator coil on the stator on the same workbench one by one, including tail shaping, tail binding, head wire arranging, head lead welding, and head binding of the exposed coil at both ends of the stator. In this operation method, the worker needs to manually complete the specific operation of each process, and needs to frequently adjust the position and state of the stator coil in a limited space.
