[0052] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0053] Combined with Figure 1 As shown, this embodiment provides a packaging box assembly device, including a body 1 and a carrier mechanism 2 installed on the body 1, a first feeding mechanism 3, a second feeding mechanism 4, a third feeding mechanism 5, a bending mechanism 6, a first gluing mechanism 7, a second gluing mechanism 8, a pushing mechanism 9 and a pressing mechanism 10 and other functional mechanisms.

[0054] In this embodiment, a first workstation, a second workstation, a third workstation and a fourth workstation are provided on the machine body 1. It should be noted that the above four workstations are only used for installing different functional mechanisms, and the work area range is determined according to the size of the functional mechanism and the requirements during assembly. Therefore, this embodiment does not mark the above four workstations.

[0055] In the above structure, the carrier mechanism 2 of this embodiment is used to carry and fix the surrounding strips and the swing cover, and can be moved to the first station, the second station, the third station and the fourth station. Preferably, the number of the carrier mechanism 2 of this embodiment can be multiple to ensure the continuity and efficiency of molding.

[0056] Combined with Figure 5 and 6 As shown, the carrier mechanism 2 of this embodiment includes a first adsorption device 21 and a second adsorption device 22 connected to each other. The first adsorption device 21 and the second adsorption device 22 of this embodiment can both include negative pressure adsorption structures such as suction cups.

[0057] The first adsorption device 21 of the present embodiment is used for adsorbing the fence strips. The first adsorption device 21 is in the shape of a rectangular block, and has a horizontal first adsorption platform 211, a vertical second adsorption platform 212 and a third adsorption platform 213. The opposite ends of the first adsorption platform 211 in the length direction are connected to the upper ends of the second adsorption platform 212 and the third adsorption platform 213 respectively.

[0058] The second adsorption device 22 of this embodiment is used to adsorb the swing cover. The second adsorption device 22 has a horizontal fourth adsorption platform 221. The horizontal height of the fourth adsorption platform 221 is greater than or equal to the horizontal height of the first adsorption platform 211, so that one side of the swing cover can overlap with the top edge of the bent surrounding strip. It should be noted that the "butt joint" and "overlap joint" described in this embodiment refer to the surrounding strip, the swing cover and the box body having matching edges, and the surrounding strip is in contact with the edge of the swing cover through butt joint or overlap, and because the surrounding strip and the box body have been glued, pre-bonding can be completed.

[0059] Combined with Figure 1 and 2 As shown, in order to achieve the continuity of assembly and molding, a turntable 11 is provided on the body 1 in this embodiment, and a plurality of carrier mechanisms 2 are installed on the turntable 11 at intervals along the circumference of the turntable 11. The first station, the second station, the third station and the fourth station are located around the turntable 11. In order to realize the automatic control of the turntable 11 and accurately rotate the turntable 11 to the corresponding station, a plurality of structural parts 13 such as screws are provided at the bottom of the turntable 11 in this embodiment, and a plurality of sensor switches 12 are provided on the body 1. The plurality of structural parts 13 and the sensor switches 12 correspond to each other one by one. The sensor switches 12 detect the distance between the structural parts 13, which can help the control mechanism (such as a processor, etc.) to rotate the turntable 11 to the corresponding position.

[0060] The first feeding mechanism 3 of this embodiment is used to move the fence strip to the carrier mechanism 2 located at the first station. There are many structural modes of the first feeding mechanism 3.

The thickness of the installation step 331 is less than or equal to the thickness of the guard bar. The lowest guard bar between the first limit baffle plate 31 and the second limit baffle plate 32 is placed on the installation step 331. When the first driving device 34 drives the push plate 33 to move, the installation step 331 drives the lowest guard bar to disengage from the first limit baffle plate 31 and the second limit baffle plate 32 to move the guard bar to the carrier mechanism 2.

The first rod 62 and the second rod 63 of this embodiment are arranged horizontally and parallelly upward, and the horizontal distance between the two is equal to the length of the first adsorption platform 211. When the strip is formed, the first rod 62 and the second rod 63 are aligned with the carrier, and then the first rod 62 and the second rod 63 are driven by the second driving device 64 to move downward to bend the two side edges of the strip to form a strip structure, that is, to complete the forming of the strip. The bending mechanism 6 can greatly improve the efficiency and effect of the strip forming.

[0063] Preferably, the first rod body 62 and the second rod body 63 of this embodiment are cylindrical or round rods, and the first rod body 62 and the second rod body 63 can rotate around their own axes to prevent the fence from being damaged by friction with the fence.

[0068] Combined with Figure 9-11 As shown, the second gluing mechanism 8 of this embodiment is used to glue the box body on the third feeding mechanism 5, and specifically to glue the box body during transportation by the second conveying device 51. Therefore, the second gluing mechanism 8 of this embodiment is located on the conveying path of the second conveying device 51. The second gluing mechanism 8 of this embodiment includes a second glue gun 81 that can move up and down, front and back, left and right, and rotate. The second glue gun 81 can achieve up and down, front and back, left and right, and rotation movements through a rotating part 82 and a driving part 83. For example, the rotation of the rotating shaft is achieved by a motor, and the up and down, front and back, left and right movements are achieved by the cooperation of a linear reciprocating motion part and rotation.

[0069] Preferably, the second gluing mechanism 8 of this embodiment may also include a glue furnace (not shown in the figure) arranged on the conveying path of the second conveying device 51. The glued floor cover is heated and baked in the glue furnace, and then the floor cover and the inner strip are assembled together through the pressing mechanism 10.

[0076] The turntable 11 then rotates the carrier mechanism 2 to the fourth station, and the third loading mechanism 5 loads the box body.
