In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0081] After a product is manufactured, it is usually packaged in a box to provide necessary protection and enhance its value. Currently, the materials and shapes of common packaging boxes on the market are quite diverse, and the corresponding assembly methods are also different. For example, there is a high-end wine box made of paper with a double lid. This double lid box requires the installation of a bottom lid and a top lid on the opposite inner walls of the cylindrical bottom box. To ensure the accurate fit between the bottom lid and the top lid to achieve a good seal, the existing double lid box assembly is generally done manually. Due to the different personal abilities and habits of the operators, the assembly sequence of the double lid boxes is not uniform, resulting in uneven quality and low assembly efficiency.

[0082] The assembly method and device of the double-lid packaging box provided by the present invention are used to guide the assembly of a double-lid packaging box. Figure 16The double-lid packaging box, such as a high-grade wine box, comprises a box body 200, a bottom lid 300 and a top lid 400. The box body 200 has an opening end and a bottom end arranged opposite along the height direction of the box body 200. The inner cavity wall of the box body 200 comprises a first inner side wall and a second inner side wall arranged opposite. The bottom lid 300 is mounted to the first inner side wall of the box body 200, and the top lid 400 is mounted to the second inner side wall of the box body 200. The bottom lid 300 has a cover plate structure extending out of the inner cavity of the box body 200. The cover plate structure is provided with a folded edge on the side facing the inner cavity of the box body 200. When the cover plate structure is covered on the opening end of the box body 200, the folded edge abuts against the corresponding end of the top lid 400 to form a sealing fit. It can be understood that, during the assembly process, the box body 200 has different morphological characteristics from the bottom-end-sealed cylindrical structure to the double-lid packaging box after the bottom lid 300 is mounted on the first inner side wall and the top lid 400 is mounted on the second inner side wall. However, for the convenience of description, the box body 200 is collectively referred to as the box body 200 below, and will not be described in detail.

[0083] It should be noted that the upward and downward directions, the transverse direction and the longitudinal direction referred to below do not constitute a limitation on the structure and movement mode of the related device, but are only for the convenience of describing the technical solutions of the double-lid packaging box assembly method and device. The upward and downward directions can be vertical directions, and the transverse direction and the longitudinal direction can be two directions arranged at an intersection angle. The intersection angle is not limited to 90°, and can be adjusted according to actual needs, such as the space size of the working room and the specific structure and process of the double-lid packaging box. Details will not be described below.

[0084] In view of the above, the present application provides a double-lid packaging box assembly method, Figures 1 to 5 The double-lid packaging box assembly method provided by the present application has the following advantages. Figures 6 to 18 The double-lid packaging box assembly device provided by the present application has the following advantages.

[0085] Please refer to Figure 1 , Figure 6 and Figure 9 In the first embodiment of the double-lid packaging box assembly method provided by the present application, the double-lid packaging box assembly method comprises the following steps:

[0086] Step S10: moving the box body 200 from the box body feeding station 11 to the bottom lid assembly station 13;

[0087] In the embodiment, the box loading station 11 and the bottom cover assembling station 13 are formed on the rack 1; the box 200 is loaded at the box loading station 11, and a sufficient number of boxes 200 are stored in various ways at the box loading station 11 for the box loading mechanism 2 to sequentially and orderly transfer to the box conveying mechanism 3, and the box conveying mechanism 3 automatically carries the box 200 into the bottom cover assembling station 13, and the action of the box loading mechanism 2 and the conveying path of the box conveying mechanism 3 are strictly unified and efficient.

[0088] Step S20: moving the bottom cover 300 into the box 200 at the bottom cover assembling station 13 and fixing it to the first inner side wall of the box 200;

[0089] In the embodiment, the bottom cover mounting mechanism 4 moves the bottom cover 300 to the bottom cover assembling station 13 and enters the box 200 from the open end of the box 200, when the bottom cover mounting mechanism 4 operates the bottom cover 300 to extend to a preset position in the box 200, continues to operate the bottom cover 300 to move towards the first inner side wall of the box 200 and is fixedly mounted to the first inner side wall of the box 200, completing the assembly of the bottom cover 300 in the box 200. The specific activity scheme of the bottom cover mounting mechanism 4 is determined according to the specific position of the bottom cover assembling station 13 on the rack 1 and the specific placement direction of the box 200; since the position of the bottom cover assembling station 13 on the rack 1 is relatively fixed and the mounting position of the box 200 on the bottom cover assembling station 13 is relatively fixed, as long as the movement scheme of the bottom cover mounting mechanism 4 for each bottom cover 300 is unified, the mounting effect of each bottom cover 300 on the box 200 can be ensured to be consistent, which helps to ensure the assembly quality of the bottom cover 300.

[0090] Step S30: moving the box 200 from the bottom cover assembling station 13 to the top cover assembling station 14;

[0091] In the embodiment, the rack 1 is provided with the top cover assembling station 14 on the side opposite to the bottom cover assembling station 13 facing the box loading station 11; when the box 200 completes the assembly of the bottom cover 300 at the bottom cover assembling station 13, the box conveying mechanism 3 conveys the box 200 along a preset path to the top cover assembling station 14, ensuring that the position of each box 200 on the top cover assembling station 14 is accurate and consistent.

[0092] Step S40: moving the top cover 400 into the box 200 at the top cover assembling station 14 and fixing it to the second inner side wall of the box 200;

[0093] In the present embodiment, the top cover mounting mechanism 5 moves the top cover 400 to the top cover assembly station 14, and into the box body 200 from the open end of the box body 200, and towards the second inner side wall of the box body 200, to fix the top cover 400 to the second inner side wall of the box body 200. Similarly to the bottom cover mounting mechanism 4 described above, the specific activity scheme of the top cover mounting mechanism 5 can be determined according to the specific position of the top cover assembly station 14 on the rack 1 and the specific placement orientation of the box body 200.

[0094] Step S50: moving the box body 200 from the top cover assembly station 14 to the box body unloading station 12.

[0095] In the present embodiment, the rack 1 is provided with a box body unloading station 12 on the side of the top cover assembly station 14 opposite to the bottom cover assembly station 13; when the box body 200 is assembled with the top cover 400 on the top cover assembly station 14, the assembly of the box body 200 is basically completed, and the box body 200 can be unloaded under the carrying of the box body conveying mechanism 3 for subsequent processes.

[0096] In the technical solution provided by the present application, the box body 200 is driven to move sequentially to the box body loading station 11, the bottom cover assembly station 13, the top cover assembly station 14, and the box body unloading station 12; when the box body 200 is moved to the bottom cover assembly station 13, the bottom cover 300 is driven to enter the box body 200 from the open end of the box body 200 and is fixed to the first inner side wall of the box body 200, automatically completing the assembly of the bottom cover 300; then, when the box body 200 is moved to the top cover assembly station 14, the top cover 400 is driven to enter the box body 200 from the open end of the box body 200 and is fixed to the second inner side wall of the box body 200, automatically completing the assembly of the top cover 400. In the present application, the box body 200 is automatically completed from the initial loading operation to the final unloading operation by the equipment, the assembly sequence is uniform and does not interfere with each other, which helps to improve the assembly quality and assembly efficiency of the box body 200.

[0097] Next, please refer to Figure 2 , in combination with Figures 15 to 17 , in the second embodiment of the assembly method of the double-cover packaging box provided by the present application, the step S20 comprises:

[0098] Step S21: applying adhesive on the lower surface of the bottom cover 300;

[0099] It can be understood that there are many technical solutions for fixing the bottom cover 300 to the first inner side wall of the box body 200. For example, according to different materials of the bottom cover 300 and the first inner side wall, the bottom cover 300 and the first inner side wall can be fixed by, for example, heat melting, pressing, etc. However, since the double-cover packaging box in the present design mainly refers to a high-end wine box, which is generally made of relatively hard paper, and considering the cost, the present design chooses to fix the bottom cover 300 and the first inner side wall of the box body 200 by adhesion. Based on this, the first inner side wall can be coated with adhesive, or the bottom cover 300 can be coated with adhesive as in the present embodiment. However, since the box body 200 is in a cylindrical structure with a closed bottom end, the scheme of extending the glue applying device into the inner cavity of the box body 200 for coating has the problems of inconvenience in coating and easy glue pollution. In the present embodiment, the bottom cover 300 is in a plate shape, which has the characteristics of easy control and convenience in coating glue in the glue coating area. The bottom cover 300 is longer and heavier than the top cover 400. Therefore, during the conveying process of the box body 200, the first inner side wall of the box body 200 can be arranged below the second inner side wall. At this time, the bottom cover 300 is fixedly installed on the first inner side wall below, and the adhesive needs to be coated from below the bottom cover 300 towards the lower surface of the bottom cover 300.

[0100] Step S22: lifting the bottom cover 300 above the first inner side wall of the box body 200;

[0101] In the present embodiment, the bottom cover mounting mechanism 4 first lifts the bottom cover 300 above the first inner side wall of the box body 200, but not higher than the second inner side wall of the box body 200. Of course, the bottom cover mounting mechanism 4 can also adjust the lateral position of the bottom cover 300 so that the bottom cover 300 is aligned with the open end of the box body 200, ensuring that the bottom cover 300 can smoothly enter the box body 200 under the carrying of the bottom cover mounting mechanism 4, avoiding interference with any inner side wall of the box body 200.

[0102] Step S23: moving the bottom cover 300 into the box body 200 at the bottom cover assembly station 13;

[0103] In the present embodiment, the bottom cover mounting mechanism 4 moves the bottom cover 300 into the box body 200 of the bottom cover assembly station 13 and stops after extending to a preset depth. The preset depth can be adjusted according to the specific parameters of the double-cover packaging box. For example, when the length of the bottom cover 300 except the cover plate part is equivalent to the length of the inner cavity of the box body 200 in a double-cover packaging box, the distance from the opening end of the box body 200 to the bottom wall of the inner cavity is the preset depth described above. The bottom cover mounting mechanism 4 stops moving the bottom cover 300 when the bottom end of the bottom cover 300 abuts against the bottom wall of the inner cavity of the box body 200. When the length of the bottom cover 300 except the cover plate part is half the length of the inner cavity of the box body 200 in a double-cover packaging box, the distance from the opening end of the box body 200 to the middle part of the inner cavity is the preset depth described above. The bottom cover mounting mechanism 4 stops moving the bottom cover 300 when the bottom end of the bottom cover 300 reaches the middle part of the inner cavity of the box body 200.

[0104] Step S24: Pressing the bottom cover 300 downward to adhesively fix the first inner side wall of the box body 200.

[0105] In the present embodiment, the above steps can ensure that the bottom cover 300 is in a position directly above the first inner side wall. Then, the bottom cover mounting mechanism 4 operates the bottom cover 300 to press downward to abut against the first inner side wall of the box body 200 and continues to apply force downward to ensure that the bottom surface of the bottom cover 300 is tightly attached to the first inner side wall. Thus, the installation of the bottom cover 300 in the box body 200 is completed.

[0106] Further, referring to Figure 3 , in combination with Figure 15 , Figure 16 and Figure 18 , in the third embodiment of the assembly method of the double-cover packaging box provided by the present application, the step S40 comprises:

[0107] Step S41: Coating adhesive on the upper surface of the top cover 400;

[0108] In the present embodiment, similarly to the bottom cover 300 described above, based on the consideration of reducing the economic cost while ensuring that the top cover 400 can be firmly mounted to the second inner side wall of the box body 200, the upper surface of the top cover 400 can be coated with adhesive instead of the second inner side wall, which has the advantages of convenient coating and intuitive coating process. The adhesive coating operation of the top cover 400 can be substantially the same as that of the bottom cover 300, except that the adhesive discharge direction of the adhesive discharge device is different. Specifically, the adhesive discharge device can include a first adhesive discharge device 44 for coating the bottom cover 300 and a second adhesive discharge device 53 for coating the top cover 400, wherein the adhesive discharge surface of the first adhesive discharge device 44 is upwardly arranged, and the adhesive discharge surface of the second adhesive discharge device 53 is downwardly arranged.

[0109] Step S43: air drying the adhesive coating position of the top cover 400;

[0110] It should be noted that the present embodiment air dries the adhesive coating position of the top cover 400 by the air drying device 54, but does not limit the drying degree of the adhesive. For different types of adhesives, the adhesion effect is not strictly proportional to the humidity, and the activity of the components of some adhesives reaches the highest under a certain humidity ratio, so the adhesive coating position of the top cover 400 can be air dried according to the specific application requirements, and the adhesion effect of the adhesive is substantially optimized by adjusting the humidity of the adhesive.

[0111] Step S44: moving the top cover 400 into the box body 200 at the top cover assembly station 14;

[0112] In the present embodiment, the top cover mounting mechanism 5 operates the position of the top cover 400 slightly lower than the height of the second inner side wall of the box body 200, and adjusts the relative position of the top cover 400 and the box body 200, so that after the top cover 400 is aligned with the open end of the box body 200, the top cover 400 is moved into the box body 200 at the top cover assembly station 14.
