The other end of each third return spring 3034 is fixedly connected to the bottom of the positioning notch 1024. A limit plate 303 is fixedly connected to the top of each driving plate 3033. This arrangement ensures that the defocused lens is retained in place when it is being fitted, and will not move away from the feed port 1023 due to downward movement along the inclined plate 103.

[0030] The implementation principle of the automatic feeding mechanism for assembling defocused lenses of this embodiment is as follows: First, the staff places the defocused lens into the inner cavity of the storage hopper 104. When the defocused lens is placed, the staff starts the servo motor 201. When the servo motor 201 is running, it can drive the threaded rod 2011 to rotate. When the threaded rod 2011 rotates, it can drive the threaded sleeve 2012 to move horizontally with the assistance of the connecting rod 2013 and the rectangular notch 1011. When the connecting rod 2013 moves horizontally, it can drive the pushing plate 2014 to move horizontally, pushing the defocused lens at the bottom of the storage hopper 104. When the connecting rod 2013 moves horizontally, it will be able to drive the second tilting block 2032 to move vertically downward with the assistance of the second slide groove 203 and the second slider 2031. When the second tilting block 2032 moves vertically downward, it will be able to drive the connecting rod 2034, the second moving rod 2035 and the fixed plate 2037 to move vertically downward. When the fixed plate 2037 moves vertically downward, the wedge block 2036 will lose its limit, so that the fourth return spring provided in the inner cavity of the slide rail 2042 can drive the first push plate 204 to reset, thereby blocking one of the feed ports 1023. At the same time, when the connecting rod 2013 continues to move, it will be able to squeeze the first inclined block 2022 and move vertically downward with the assistance of the first slide groove 202 and the first slider 2021. When the first inclined block 2022 moves vertically downward, it will be able to drive the first moving rod 2024 to move vertically downward. When the first moving rod 2024 moves vertically downward, it will be able to pull the second push plate 2061 through the movable rod 2062 to move horizontally with the assistance of the slide rail 2042 and leave one of the feed ports 1023. At this time, the flip plate 301 provided in the feed port 1023 will be able to open with the assistance of the torsion spring 3022. When the turnover plate 301 is opened, it can drive the rotating rod 3011 to rotate. Through the guide sliding slot 3012 and the slidingly arranged guide sliding block on the rotating rod 3011, the guide sleeve 3014 can be driven to move horizontally with the assistance of the guide rod 3015. Through the guide sleeve 3014, the positioning rod 3016 can be driven to move horizontally, and the rotating plate 302 can be driven to rotate with the assistance of the rotating rod 3021. At this time, the pushed out defocus lens has already fallen from the inclined plate 103 to above the first feeding port 1023 of the working box 102, and the rotating plate 302 is rotated into the side wall mounting slot. When the defocus lens fits, it will fall from the feeding port 1023 and enter the discharging plate 1022 for discharging. When the defocus lens does not fit the first feeding port 1023, it will be pushed by the rotating plate 302. The limiting plate 303 can be vertically moved downward with the assistance of the third sliding slot 3031, the third sliding block 3032 and the driving plate 3033, so that the defocus lens enters the next feeding port 1023 for detection (at this time, the opening of the feeding port 1023 is when the connecting rod 2013 is reset). In this way, the defocus lens can be classified and discharged.
