The cooling fan currently used in laptops mainly includes fan blades and bearings, such as Figure 7 As shown, the bearing is composed of a shell, and wear-resistant sheets, washers, rotors and copper covers assembled in the shell. Since the rotor of this type of bearing has no prominent contour features on its surface, it is difficult to identify it through a visual module, so it is not suitable for loading with a vibration plate.

Since the manual loading method is inefficient and cannot meet the needs of large-scale production, it also increases labor costs and safety hazards. Therefore, it is very necessary to develop an assembly device that can realize automatic loading of bearing rotors. Utility Model Content
