[0050] The working process is roughly as follows: the vibrating disc delivers the hinge 12 to the conveying channel of the feeding table in a preset posture, the pushing mechanism 2 pushes the hinge 12 to move along the conveying channel in the preset posture to the welding station 8, at this time, the welding base 5 on the welding station 8 is pre-loaded with the spectacle footrest 1, when the hinge 12 reaches the welding station 8, the hinge 12 can be directly conveyed to be in contact with the welding surface of the footrest body 11, and then the positioning mechanism 4 acts to position the footrest body 11 and the hinge 12, so that the hinge 12 can be accurately positioned at the welding position on the welding surface of the spectacle footrest 1, and the footrest body 11 can be accurately positioned on the bearing surface 51 of the welding base 5, so that the automatic loading of the hinge 12 is completed, and the efficiency is effectively improved compared with manual loading. Then the ultrasonic welding head 7 ultrasonically welds the hinge 12 and the footrest body 11, after the welding is completed, the positioning mechanism 4 releases the positioning of the spectacle footrest 1, and the pushing mechanism 2 acts again to push the spectacle footrest 1 after the welding to the direction close to the guide mechanism 3, so that the spectacle footrest 1 is pushed into the guide mechanism 3 and collected into the material collecting mechanism through the guide mechanism 3, so that the automatic unloading of the spectacle footrest 1 is completed, the unloading efficiency is effectively improved compared with manual loading, and the unloading process does not need manual participation, and the automation degree is higher.
