Compared with the existing adsorption component adopting the air cylinder and the electromagnet 22, the nut adsorption structure 20 provided by the utility model has the advantages of small volume, light weight, high flexibility, high stability, simple structure and easiness in replacement and maintenance.

Specifically, when the nut 50 needs to be adsorbed, the hollow copper pipe 23 is moved to the position right above the nut 50 to be adsorbed by using a robot, and then the nut adsorption structure 20 is driven to move downwards until the nut 50 abuts against the bottom surface of the hollow outer sleeve 21, and the magnet 22 adsorbs the nut 50 to complete the adsorption work of the nut 50; when the nut 50 is fed, the hollow copper pipe 23 is aligned with the insert needle of the nut 50 at the position where the nut 50 needs to be placed by using a robot, and then the nut adsorption structure 20 is driven to move to the embedded position until the nut 50 is completely in place, and at the moment, the magnet 22 and the nut 50 are in a separated state; finally, the robot drives the hollow copper pipe 23 to align with the embedded nut 50, so that the lower end surface of the hollow copper pipe 23 just abuts against the upper end surface of the embedded nut 50, and whether the nut 50 is embedded or not is detected by the optical fiber sensor 24.
