The inductor insertion device loads the inductor into the carbon brush holder obtained in the previous step, and places the obtained carbon brush holder on the carbon brush holder jig and continues to convey it along the production line track; S6. The capacitor assembly device assembles the lantern holder capacitor obtained in S3 on the carbon brush holder jig on the carbon brush holder obtained in the previous step, and transfers the obtained carbon brush holder to the torsion spring assembly device; S7. The torsion spring assembly device assembles the torsion spring on the carbon brush holder obtained in the previous step, and transfers the obtained carbon brush holder to the carbon brush assembly and welding device; S8. The carbon brush assembly and welding device loads the carbon brush into the carbon brush holder obtained in the previous step, connects and welds the carbon brush and the inductor through a wire to obtain a finished carbon brush holder, and transfers the obtained finished carbon brush holder to the detection device; S9. The detection device performs electrical detection on the finished carbon brush holder obtained in the previous step, and classifies the qualified products and unqualified products.
