[0025] In the specific working process, the operator places the sound-absorbing cotton and the base ring in the placing cylinder 8 and the first jig 6, respectively, at the opposite position of the workbench 1. The first turntable 2 rotates, and when it rotates to the side position, the magnetic return body 12 after being cleaned and magnetized is moved to the second jig 7. The limiting blocks on both sides limit the magnetic return body 12. The glue injection work is carried out through the fixed seat 3 position. The electric telescopic rod 13 works, driving the mounting seat 14 to move downward, and then driving the abutting head 15 and the glue injection head 16 to contact the magnetic return body 12. The abutting head 15 abuts against the magnetic return body 12 and contacts the second turntable 11. The second turntable 11 rotates to make the magnetic return body 12 rotate, so that the glue injection head 16 injects glue to the rotating magnetic return body 12 for one round to complete the glue coating work.

[0026] Among them, the magnetic return body 12 is located in the second jig 7, and the abutting head 15 and the glue injection head 16 are used in cooperation with the magnetic return body 12. In the specific use process, the magnetic return body 12 needs to be cleaned and magnetized and then moved to the inside of the second jig 7 by the mechanical hand. Then, the magnetic return body 12 is glued. The abutting head 15 is used to abut against the magnetic return body 12 and limit the magnetic return body 12 with the limiting blocks on both sides. The glue injection head 16 glues the magnetic return body 12. The two cooperate to better glue the magnetic return body 12, and the glue injection effect is good.

[0027] Among them, the mounting pads 5 and the placing cylinders 8 are distributed in a ring shape on the top of the first turntable 2. The second jig 7 is located in the middle position between the first jig 6 and the placing cylinder 8. Through the rotation of the first turntable 2, the corresponding materials are placed on the ring-distributed mounting pads 5 and placing cylinders 8. The base ring is placed in the first jig 6, the magnetic return body 12 is placed in the second jig 7, and the sound-absorbing cotton is placed in the placing cylinder 8.
