The empty tooling 100 is transported from the feeding conveyor belt 11 to the return conveyor belt 12 by a robot or by adding the handling mechanism 60 and flows back to the position adjacent to the entrance of the feeding conveyor belt 11. Then, it is picked up by the robot or the handling mechanism 60 and put back to the feeding conveyor belt 11 for reuse.

[0027] Furthermore, multiple openings are provided on the guide plate 332 to reduce weight.

[0028] Furthermore, a first connecting frame 337 is provided below the recycling box 331. The first connecting frame 337 is used to clamp to the glue application mechanism 30 for easy connection and installation.

The top-feeding component 53 is used to push out the finished magnetic circuit in the tooling 100. The adsorption head 521 adsorbs the finished magnetic circuit and moves it above the detection module 54 for visual inspection. The finished magnetic circuit that passes the inspection falls to the unloading track 55 for collection. Alternatively, a recycling container can be set to collect products that fail to pass the inspection. Of course, the unqualified products can also be recycled through the unloading track 55, and the qualified products can be collected by the recycling container.

[0031] The top-feeding assembly 53 includes a drive motor 531, a lead screw transmission module 532, and a top-feeding plate 533. The drive motor 531 drives the lead screw transmission module 532 to move, and the lead screw transmission module 532 drives the top-feeding plate 533 to make a vertical linear displacement. The top-feeding plate 533 is provided with a plurality of top-feeding pins 534. The positions of the top-feeding pins 534 correspond to the holes on the tooling 100. Thus, when the third bearing assembly 51 drives the tooling 100 to the position of the top-feeding assembly 53, the magnetic circuit product in the tooling 100 can be lifted from below by the top-feeding pins 534 for vacuum adsorption and removal by the adsorption head 521.
