[0077] In summary, the working principle of a multi-stage tray forming device provided in this application is as follows:

[0078] Loading the tray: first place the silo clip 21 filled with trays on the discharge port bracket 22, the first transplanting assembly 31 moves forward to move the first suction cup assembly 33 to the bottom of the discharge port bracket 22, then the first lifting assembly 32 moves upward, the first suction cup assembly 33 touches the tray at the lowest end in the silo clip 21 and sucks it, the first lifting assembly 32 descends, the tray at the lowest end is pulled out of the silo clip 21, and one material removal is completed;

[0079] Primary forming: The first transfer assembly 31 withdraws from the discharge port bracket 22 and moves to the bottom of the primary forming upper mold fixture 412. At this time, the downward pressure power assembly 411 descends, and the top suction cup assembly 4122 of the primary forming upper mold fixture 412 contacts the card holder on the first suction cup assembly 33. The top suction cup assembly 4122 in the primary forming upper mold fixture 412 absorbs the card holder on the first suction cup assembly 33, and the vacuum of the first suction cup assembly 33 is closed, and the card holder is transferred from the first suction cup assembly 33 to the primary forming.

Subsequently, the pressing and fixing assembly 51 is raised, and the bottom forming telescopic end of the bottom forming assembly 54 is extended upward, so that the top plate 542 is pushed upward from the second avoidance groove 562, the bottom flap 85 is folded upward, and then the side ear forming telescopic end of the side ear forming assembly 55 is extended, and under the support of the top plate 542, the side ear 85 can be folded inward, and then the side ear forming assembly 55 is withdrawn, and the side ear forming is completed. Finally, the oblique forming assembly 52 turns off the vacuum, and retracts together with the oblique forming auxiliary assembly 53, the bottom forming assembly 54 and the side ear forming assembly 55, and the forming operation of a tray is completed.

[0082] Card tray unloading: the telescopic lifting end of the lifting mechanism 61 moves upward so that the push plate set on the telescopic lifting end moves to the opening of the second avoidance groove 563, so that the push plate is located at the rear end of the formed card tray 80, and then the telescopic pushing end drives the lifting fixed end to move toward the direction of the unloading conveyor line 63, and then drives the secondary formed card tray 80 to move to the unloading conveyor line 63 through the telescopic pushing end and the push plate, and the unloading is completed.
