The entire production process does not require manual operation, saving manpower.
[0048] The structure of the present invention is reasonable, the design is novel, and the practicability is strong. The stator 100 is rotated by the indexing mechanism 1, so that the stator 100 can be continuously inserted with a plurality of terminals. The stator 100 is lifted by the lifting cylinder 21 to facilitate the loading and unloading of the stator 100. The terminal aisle 39 presses the terminal strip 105 with a pressing plate 37, and the feeding of the terminal strip 105 is stable, ensuring that the terminal cutting mechanism 5 can accurately and stably complete the punching of the terminals. The terminal slots 101 of the stator 100 are positioned by closing two guiding blocks, so that the guiding slots 67 communicate with the terminal slots 101, ensuring smooth insertion of the terminals 102 into the slots.
[0049] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
