[0048] The working principle of the lower-pulling type uninterrupted feeding device in the utility model is (taking the direction of Figure 2 as the reference direction for description):

[0049] Initial state, all the hoppers in the four hopper assemblies 10 are full, the movable part of the first electric cylinder 22 is at the lowermost end of its stroke, the movable part of the second electric cylinder 23 is at the leftmost end of its stroke, the piston rod of the first pneumatic cylinder 28 is retracted, and the piston rod of the second pneumatic cylinder 34 is retracted;

[0050] (1) Positioning and taking of the material by the positioning and taking mechanism 20

[0051] The second electric cylinder 23 drives the first mounting plate 211 to move right, thereby driving the positioning platform 24 and the first suction cup 21 to move right as a whole to the position directly below the hopper assembly 10. The movable part of the first electric cylinder 22 extends upward to drive the first suction cup 21 to ascend until it stops ascending when the first suction cup 21 contacts the bottom surface of the lowermost one of the cards 1 in the hopper assembly 10. The first suction cup 21 sucks the lowermost one of the cards 1 in the hopper assembly 10, and the movable part of the first electric cylinder 22 retracts downward at the same time. Meanwhile, the first suction cup 21 pulls the lowermost one of the cards 1 downward from the taking opening (the remaining cards 1 fall under their own gravity). The first suction cup 21 continues to descend and places the card 1 on the positioning platform 24, and then the first suction cup 21 releases the card 1.

[0052] The second electric cylinder 23 drives the first mounting plate 211 to move left, thereby driving the positioning platform 24 and the first suction cup 21 to move left as a whole. Meanwhile, the piston rod of the first pneumatic cylinder 28 extends to drive the push plate 27 to extend, and the first baffle 25, the second baffle 26, and the push plate assembly collectively and accurately position the card 1.

[0053] (2) Taking and placing of the material by the taking and placing mechanism 30

[0054] The movable part of the second electric cylinder 23 moves to the leftmost end of its stroke, at which time the positioning of the card 1 on the positioning platform 24 has been completed. The arm of the mechanical hand rotates to move the taking and placing mechanism 30 to the position directly above the positioning platform 24. The piston rod of the second pneumatic cylinder 34 extends to drive the second suction cup 33 to descend. When the second suction cup 33 contacts the card 1, it stops descending. The second suction cup 33 sucks the card 1. The piston rod of the first pneumatic cylinder 28 retracts to release the card 1. The piston rod of the second pneumatic cylinder 34 retracts to take away the card 1 on the positioning platform 24. The arm of the mechanical hand rotates to move the card 1 in the taking and placing mechanism 30 to the position directly above the carrier of the next work station (at this time, the first electric cylinder 22, the second electric cylinder 23, and the first pneumatic cylinder 28 of the positioning and taking mechanism 20 have returned to the initial state to take the material in the next cycle). The arm of the mechanical hand descends, the pin 32 is inserted into the pin hole of the carrier to position, the piston rod of the second pneumatic cylinder 34 extends to place the card 1 on the carrier, the second suction cup 33 releases the card 1, the piston rod of the second pneumatic cylinder 34 retracts, and the arm of the mechanical hand rises to reset. The above steps are repeated to feed the cards.
