[0020] In order to more stably and reliably complete the assembly of the inner base 22 and realize the automatic flow of the packaging box 12, the width of the packaging box conveyor belt 15 is not less than twice the width of the packaging box 12, a first guide rod 16 is installed on one side of the packaging box conveyor belt 15, and a second guide rod 14 is installed on the middle and upper part of the packaging box conveyor belt 15. A packaging box baffle 11 is installed on the frame 17 at the same time below the automatic robot arm 7, behind the assembly cylinder 20, and above the packaging box conveyor belt 15. The assembly cylinder 20 is installed on the frame 17 through the mounting bracket 21 and is located near the first guide rod 16. The push rod of the assembly cylinder 20 is connected to the vertical assembly push plate 19 for clamping the packaging box 12, and the push rod of the assembly cylinder 20 has an angle of 30-60° with the horizontal direction so that when the push rod of the assembly cylinder 20 is retracted, the distance between the assembly push plate 19 and the packaging box conveyor belt 15 after moving upward is greater than the height of the packaging box 12. A box pushing cylinder 8 is installed at a position close to the first guide rod 16 and corresponding to the assembly cylinder 20, and the push rod of the box pushing cylinder 8 is connected to a vertical box pushing plate (not visible in the figure) for supporting and pushing the packaging box 12.

[0021] In order to guide the packaging box 12 and facilitate the installation of each cylinder, there are two box-dividing cylinders 3 and they are respectively located on the outside of the first guide rod 16 and on the side of the second guide rod 14 away from the first guide rod 16; there are two gluing cylinders 6 and they are respectively located on the outside of the first guide rod 16 and on the side of the second guide rod 14 away from the first guide rod 16; the box-dividing cylinders 3 and the gluing cylinders 6 located above the packaging box conveyor belt 15 are installed on the frame 17 through a horizontal cylinder mounting plate 18.

[0022] In order to facilitate the installation of each proximity sensor, the sub-box proximity sensor 13 and the glue proximity sensor 2 are both installed on the first guide rod 16.

[0023] In order to achieve the clamping, movement and installation of the inner base 22, a movable base 9 capable of moving horizontally and vertically is installed on the automatic robotic arm 7. The movable base 9 can be placed in the packaging box 12. A suction cup 10 for adsorbing the inner base 22 is installed under the movable base 9. The suction cup 10 is connected to an air source (not shown in the figure) through an air pipe, and a control input end of the suction cup 10 is correspondingly connected to a control output end of the controller.

[0024] In order to facilitate the conveying of the inner base 22 and ensure that it is in a fixed position after being blocked to facilitate accurate clamping, the inner base conveyor belts 24 are two parallel to each other, and the distance between the two inner base conveyor belts 24 is smaller than the total width of the inner base 22 and larger than the width of the raised part of the inner base 22.

After the gluing is completed, the separation box cylinder 3 and the gluing cylinder are both operated to release the corresponding packaging box 12, and the first packaging box 12 moves to the bottom of the automatic mechanical arm 7 and is blocked by the packaging box baffle 11. Then the assembly cylinder 20 is operated to clamp and position the first packaging box 12, and then the automatic mechanical arm 7 is operated, the moving seat 9 moves upward, and then moves laterally in the direction close to the inner base 22. Then the vacuum air source of the suction cup 10 is turned on to generate suction, sucking an inner base 22, and then moving upward, and then moving laterally in the direction close to the first packaging box 12 to be assembled, and then moving downward until the inner base 22 is bonded to the bottom of the first packaging box 12, and then the moving seat 9 moves upward to reset, and then the box pushing cylinder 8 is started, driving the box pushing plate to push the first packaging box 12 after the inner base 22 is assembled to move in the direction close to the assembly cylinder 20, and after pushing the first packaging box 12 to the other side close to the packaging box conveyor belt 15, the first packaging box 12 avoids the packaging box baffle 11 and is conveyed to the next station by the packaging box conveyor belt 15, completing the entire process of assembling the inner base 22; at the same time, the second packaging box 12 repeats the above process of the first packaging box 12, and the third packaging box 12 repeats the above process of the second packaging box 12, and so on, completing the assembly process of all packaging boxes 12 and the inner base 22.
