third case: when the width of the filling gap (4) of the isolation adhesive tape between the coil tail coil (7 a) and the coil secondary tail coil (7 b) which are continuously shot by the lens (21) of the vision camera (20) is larger than the thickness of the isolation adhesive tape pulled out of the isolation adhesive tape roll (12), the telescopic rod (22) is immediately controlled to rapidly extend and retract at the moment, so that the hammering fitting surface (28) of the hammering block (27) moves to be attached to and hammered on the adhesive tape attaching surface (8) and then rapidly separated from the adhesive tape attaching surface (8); if the third condition is continuously present, the rotational speed of the columnar core (9) is adaptively increased.
