The robot assembly places the inductor frame 38 in the front end slot position of the hard silicone tube 36. The negative pressure air pump device 35 is started with negative pressure, and negative pressure suction is generated at the air holes of the rubber pad 37 to negatively adsorb and limit the inductor frame 38. The wire feeding device of the fixed wire feeding mechanism is started, so that the copper wire passes through the square hole of the inductor frame 38.
