The first lead portion 21 of 20 is operated to connect the first lead portion 21 to the first contact terminal 31.

The second winding unit 400 configured as described above receives the drum core 10 in a state where the first step working process is completed by the first winding unit 300 through the index table 110, and performs the second step working process. First, as shown in FIG. 9A, when the first front portion 21 of the winding coil 20 is supplied to the drum core 10 in an externally protruding state, as shown in FIG. 9B. The pressing frame 423 moves downward and the pressing protrusion 424 presses and fixes the drum core 10. Thereafter, as shown in FIG. 9C, the holder module 410 moves downward, and grips the first lead portion 21 of the winding coil 20 through the holder rod 413 and the holder sleeve 412. , The first lead portion 21 is connected to the first contact terminal 31. When the first front part 21 is connected to the first contact terminal 31 as described above, the second winding cutting module 440 operates and cuts the winding coil 20 at the corresponding point, thereby preventing the second winding unit 400. The work process is complete.

When the first and second end portions 22 and 22 of the winding coil 20 are connected to the first contact terminal 31 and the second contact terminal 32 of the drum core 10 through this process, the welding is then performed. The unit 500 is laser welded at each contact terminal point and discharged to the outside.
