[0024] Specifically, in order to ensure that the object can be accurately adsorbed at the specified position, corresponding adjustments need to be made according to the position of the object. First, start the first motor 2 to drive the worm 11 to rotate. Since the meshing connection between the worm 11 and the worm wheel 8 can effectively transmit large torque and moment, the rotation of the worm 11 will drive the worm wheel 8 to rotate accordingly. Then the rotation of the worm wheel 8 will further drive the threaded rod 10 to rotate. Under the action of the threaded rod 10, the first slider 13 will move along the preset path, thereby driving the second table 9 to adjust its position. When the second table 9 moves to a suitable position.

[0028] Specifically, the second motor 18 is started to drive the screw rod 20 to rotate. The rotation of the screw rod 20 will drive the second slider 22 to slide along the preset track to complete the longitudinal adjustment of the electromagnet 14. Then the third motor 23 is driven by the forward and reverse screw rods 25 to start to move. Then the hanging rod 17 moves driven by the forward and reverse screw rods 25. Finally, in order to ensure a firm connection between the hanging rod 17 and the electromagnet 14, it is necessary to use the lock 15 to fix it. The whole operation process is rigorous and orderly, ensuring the stable operation of the equipment.

[0029] Working principle: push the swivel caster 1 to the top of the electromagnet 14, then start the third motor 23, and drive the fixedly connected positive and negative screws 25 to rotate through the third motor 23, thereby driving the hanging rod 17 to a suitable position through the positive and negative screws 25, and fixing the hanging rod 17 to the electromagnet 14 through the lock 15, and then push the swivel caster 1 to the position for adsorbing items, start the first motor 2, and drive the fixedly connected worm 11 to rotate through the first motor 2, and then drive the meshing worm wheel 8 to rotate through the worm 11, and then drive the fixedly connected threaded rod 10 to rotate through the worm wheel 8, and then drive the threaded first slider 13 to move through the rotation of the threaded rod 10, thereby driving the fixedly connected second table 9 to move through the first slider 13 to reach the adsorption position, and then start the second motor 18, and drive the fixedly connected screw 20 to rotate through the second motor 18, and then drive the threaded second slider 22 to move through the rotation of the screw 20.
