This realizes the convenient box capping of the automated box capping equipment, reducing the labor intensity of manual labor and improving the efficiency of the automated box capping equipment in capping the box.

[0019] Working Principle: When using the automated box-lid packaging equipment, the box body 4 is placed inside the support plate 3 and limited by the protrusion 10. The second push rod 15 drives the third push rod 16 and the electric suction cup 17 to move upward. The third push rod 16 drives the electric suction cup 17 to move upward, so that the electric suction cup 17 adsorbs a group of box bodies 4 above the protrusion 10. When adsorbed, the third push rod 16 is opened in the opposite direction, so that the third push rod 16 drives the electric suction cup 17 to move downward. Under the elastic support of the box body 4, the box body 4 is disengaged from the protrusion 10. The first lead screw moving assembly 11 drives the second push rod 15, the third push rod 16, and the electric suction cup 17 to move downward. The tray 17 and the box body 4 move to the lid area. When the lid needs to be closed, the infrared sensor 26 detects that the box body 4 has moved to the lid area. The infrared sensor 26 then transmits the signal to the surface of the display control panel 5 after processing by the processor 6. The display control panel 5 is operated to open the second push rod 15 in reverse, causing the second push rod 15 to drive the third push rod 16, the electric suction cup 17, and the box body 4 to move downwards. Under the limitation of the right inclined block 14 and the left inclined block 22, the box body 4 descends to the lid area. The first push rod 12 drives the first push plate 13 to move, causing the first push plate 13 to move to the side of the box body 4 to push it down. The fifth push rod 30 drives the pressure plate 32 to move downwards, pressing the box body 4 down. The eighth push rod 38 drives the third irregular frame 39 to move, causing the dustproof wing 20 to fold into the box body 4. The fourth push rod 29 drives the first irregular frame 31 to move downwards, causing the box cover 19 to fold at a certain angle. The seventh push rod 36 drives the top block 37 to move forward, causing the tongue 21 to fold into the box body 4. The eighth push rod 38 is then opened in the opposite direction. Supported by the first concave plate 8, the eighth push rod 38 drives the third irregular frame 39 to move downwards. The frame 39 retracts, the sixth push rod 34 drives the second irregular frame 35 to move forward, the second irregular frame 35 folds the lid body 19 into the inside of the box body 4, and the fifth push rod 30 is opened in the opposite direction. Under the support of the second support frame 28, the fifth push rod 30 drives the pressure plate 32 to move upward and disengage from the box body 4. The second screw moving assembly 23 drives the second support frame 28, the first support frame 27, the fourth push rod 29, and the first irregular frame 31 to move. The first irregular frame 31 moves the box body 4 to one side and moves the box body 4 to the surface of the inclined plate 25. The box body 4 slides down and is collected through the inclined plate 25, thus completing the use of the automated lid device.

[0020] It should be noted that the first push rod 12, the second push rod 15, the third push rod 16, the fourth push rod 29, the fifth push rod 30, the sixth push rod 34, the seventh push rod 36, and the eighth push rod 38 mentioned above are electric push rods or pneumatic push rods, and can also be configured as other types of linear drive modules, which will not be elaborated here.
