[0017] In order to better achieve the purpose of the present invention, the present invention also provides a method for a piece-by-piece feeding device for box assembly, comprising the following steps: Step 1: Adjust the width range of the conveyor belt adsorption of the vacuum adsorption conveyor belt. The output end of the electric linear module moves to drive the hole-shielding belt to move, and the openings on the vacuum adsorption conveyor belt are blocked to adapt to the current size of thick cardboard. The stacked thick cardboard is placed on the rack in front of the fixed baffle. The first proximity sensor on the left side of the fixed baffle detects the stacked thick cardboard. The external controller controls the first cylinder output end of the pusher assembly to move rightward to drive the pusher plate to move rightward. The pusher plate moves to push the stacked thick cardboard onto the plate conveyor of the loading assembly. The pusher plate cooperates with the lifting plate of the lifting assembly to align the stacked thick cardboard in the left and right directions. Step 2: The third proximity sensor of the front and rear alignment assembly detects the stacked thick cardboard on the moving conveying plate of the plate conveyor, and the third proximity sensor transmits an electrical signal to the external controller. The external controller controls the plate conveyor to start and convey the stacked thick cardboard toward the middle side of the frame. At this time, the sliding rod of the front and rear alignment assembly leaves the side wall of the frame, and the compressed gas spring recovers, driving the rack to move away from the middle side of the frame. The rack moves away from the middle side of the frame and drives the gear to rotate. The gear rotation drives the rotating rod to rotate. The rotating rod rotation drives the connecting rod to move toward the center axis of the gear. The connecting rod moves toward the center axis of the gear and drives the sliding plate to move toward the center axis of the gear. The sliding plate moves toward the center axis of the gear and drives the vertical baffle to move toward the center axis of the gear, so that the stacked thick cardboard is aligned in the front and rear directions. Step 3: When the moving conveying plate of the plate conveyor approaches the middle side of the frame, the second proximity sensor on the front side of the frame detects the moving conveying plate first, and then the second proximity sensor on the rear side of the frame detects the moving conveying plate. The two second proximity sensors transmit the electrical signal at this time to the external controller, and the external controller controls the baffle assembly on the rear side of the frame to block, and the sliding rod of the front and rear alignment assembly contacts the sliding baffle of the baffle assembly, so that the front and rear alignment assembly releases the stacked cardboard, and the lower fixed frame of the front and rear alignment assembly contacts the touch switch on the sliding baffle, and the touch switch transmits the electrical signal to the external controller, and the external controller controls the plate conveyor to stop; Step 4: The fourth proximity sensor of the feeding assembly detects that there is a stacked thick cardboard on the lower side of the suction cup, and the fourth proximity sensor transmits an electrical signal to the external controller. The external controller controls the output end of the longitudinal slide cylinder to move downward to drive the suction cup to move downward, and suck up the thick cardboard. The output end of the transverse slide cylinder moves to drive the longitudinal slide cylinder and the thick cardboard to move toward the pallet assembly. After the thick cardboard contacts the pallet assembly, it continues to move to the glue coating machine. At the same time, the external controller controls the lifting mechanism to continuously lift the stacked thick cardboard. Step 5: After the stacked cardboards on the moving conveyor plate of the plate conveyor are loaded, the third proximity sensor detects that there is no stacked cardboard on the moving conveyor plate, and transmits an electrical signal to the external controller. The external controller controls the rear baffle assembly in the frame to descend and restart the plate conveyor. The plate conveyor transports the stacked cardboards on the rear moving conveyor plate to the middle side of the frame and continues to load them piece by piece.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention aligns the stacked thick cardboard in left and right directions while pre-loading by cooperating with the push plate and the lifting plate of the lifting assembly; the third proximity sensor of the front and rear alignment assembly detects the stacked thick cardboard on the moving conveying plate of the plate conveyor, and the third proximity sensor transmits an electrical signal to an external controller, and the external controller controls the plate conveyor to start conveying the stacked thick cardboard toward the middle side of the frame. At this time, the sliding rod of the front and rear alignment assembly leaves the side wall of the frame, and aligns the stacked thick cardboard in front and back directions, which is beneficial to aligning the sheets in the front and rear and left and right directions.

[0019] 2. When the moving conveying plate of the plate conveyor approaches the middle side of the frame, the second proximity sensor on the front side of the frame detects the moving conveying plate first, and then the second proximity sensor on the rear side of the frame detects the moving conveying plate. The two second proximity sensors transmit the electrical signal at this time to the external controller, and the external controller controls the rear baffle assembly in the frame to block, and the sliding rod of the front and rear alignment assembly contacts the sliding baffle of the baffle assembly, so that the front and rear alignment assembly releases the stacked thick cardboard, and the lower fixed frame of the front and rear alignment assembly contacts the touch switch on the sliding baffle, and the touch switch transmits the electrical signal to the external controller, and the external controller controls the plate conveyor to stop. After the feeding assembly conveys the stacked thick cardboard, the rear moving conveying plate of the plate conveyor of the loading assembly is placed with the stacked thick cardboard, and the plate conveyor conveys the stacked thick cardboard of the rear moving conveying plate to the middle side of the frame, which is conducive to alternating loading of double stations to ensure the continuity of loading; it is conducive to aligning the sheets in the front and back and left and right directions while performing alternating loading of double stations.

[0020] 3. The fourth proximity sensor of the feeding assembly detects that there is stacked thick cardboard on the lower side of the suction cup. The fourth proximity sensor transmits an electrical signal to the external controller. The external controller controls the output end of the longitudinal slide cylinder to move downward to drive the suction cup to move downward, and suck up the thick cardboard. The output end of the transverse slide cylinder moves to drive the longitudinal slide cylinder and the thick cardboard to move toward the pallet assembly. After the thick cardboard contacts the pallet assembly, it continues to move to the gluing machine. At the same time, the external controller controls the lifting mechanism to continuously lift the stacked thick cardboard, which is convenient for continuous loading one by one. The double-station alternating loading can be performed while the sheets are aligned in the front and back and left and right directions. The sheets can also be continuously loaded one by one, which is convenient for processing at the next station. BRIEF DESCRIPTION OF THE DRAWINGS

The first proximity sensor 24 on the left side of the fixed baffle 23 detects the stacked thick cardboard, and the external controller controls the output end of the first cylinder 21 of the pushing assembly 2 to move rightward to drive the pushing plate 22 to move rightward. The pushing plate 22 moves rightward to push the stacked thick cardboard onto the plate conveyor 31 of the loading assembly 3, and the pushing plate 22 cooperates with the lifting plate 11 of the lifting assembly to align the stacked thick cardboard in the left and right directions; Step 2: The third proximity sensor 911 of the front and rear alignment assembly 9 detects the stacked thick cardboard on the moving conveying plate 16 of the plate conveyor 31, and the third proximity sensor 911 transmits an electrical signal to the external controller, which controls the plate conveyor 31 to start conveying the stacked thick cardboard toward the middle side of the frame 1. At this time, the sliding rod 95 of the front and rear alignment assembly 9 leaves the side wall of the frame 1, and the compressed gas spring 96 recovers, driving the rack 94 to move away from the middle side of the frame 1. The rack 94 moves away from the middle side of the frame 1 and drives the gear 92 to rotate. The rotation of the gear 92 drives the rotating rod 98 to rotate.

After the thick cardboard contacts the support plate assembly 5, it continues to move to the glue coating machine 6, and at the same time, the external controller controls the lifting mechanism 33 to continuously lift the stacked thick cardboard; Step 5: After the stacked thick cardboards on the movable conveying plate 16 of the plate conveyor 31 are loaded, the third proximity sensor 911 detects that there is no stacked thick cardboard on the movable conveying plate 16, and transmits an electrical signal to the external controller. The external controller controls the rear baffle assembly in the frame 1 to descend and restart the plate conveyor 31. The plate conveyor 31 conveys the stacked thick cardboards on the rear movable conveying plate 16 to the middle side of the frame 1, and continues to load the materials one by one.
