Description

Technical Field

[0001] This invention relates to the field of packaging box installation technology, and more particularly to a folding mechanism and a packaging box installation device having the same. Background Technology

[0002] After the indoor unit of the air conditioner is assembled, it needs to be packed into a box. Currently, many boxes on the market are installed manually or using box installation devices.

[0003] Existing packaging box installation devices do not fold the box lid, so the next step after boxing, which is to close the top lid and then rotate the whole box 180°, is difficult to automate.

[0004] Therefore, a mechanism is needed that can fold the lid of the packaging box to facilitate automatic flipping of the packaging box in subsequent processes. Summary of the Invention

[0005] To overcome the problems existing in related technologies, one of the objectives of this invention is to provide a folding mechanism that can fold the lid of a packaging box, facilitating automatic flipping of the packaging box in subsequent processes.

[0006] A folding mechanism includes a platform comprising an arcuate portion and a flat portion, the arcuate portion being inclined toward the flat portion; a guide mechanism is disposed near the flat portion, the guide mechanism comprising at least two guide rods, each guide rod comprising a bent portion, the end of the bent portion near the platform extending toward an adjacent bent portion; the platform is used to fold the short side lid of a packaging box, and the bent portion is used to fold the long side lid of the packaging box.

[0007] The curved section is inclined towards the flat section and has a certain curvature. Using the curved section, the short side lid can be rotated towards the flat section, thus folding the short side lid. After folding the short side lid, the folding angle is less than 90 degrees. Then, the flat section presses down on the initially folded short side lid, making the folding angle 90 degrees. The bent end of the guide rod near the platform extends towards the adjacent bent end, pressing against the long side lid of the packaging box and folding the long side lid inward. This folding mechanism can fold both the short and long side lids of the packaging box, facilitating automatic box flipping in subsequent processes.

[0008] In a preferred embodiment of the present invention, the folding mechanism further includes a shaping frame, which is connected to the arcuate portion of the platform.

[0009] The shaping frame is connected to the curved part. Using the shaping frame can fix the curved part and increase its stability.

[0010] In a preferred embodiment of the present invention, the guide rod further includes a fixing part, which is connected to the end of the bending part away from the platform, and the fixing part is connected to the shaping frame.

[0011] The combined action of the fixing part and the shaping frame effectively secures the bending part, giving it good stability. The bending part connects with the fixing part to form a protrusion, which presses down on the long side of the box lid, creating a crease.

[0012] In a preferred embodiment of the present invention, the arc-shaped portion is connected to the planar portion, and the height of the end of the arc-shaped portion away from the planar portion is less than the height of the planar portion.

[0013] Except for the part that connects with the flat part, the height of the curved part is less than that of the flat part, so that the curved part can first contact the short side of the box lid and drive the short side of the box lid to fold inward.

[0014] A second objective of this invention is to provide a packaging box installation device, including the folding mechanism described in any of the above claims, the packaging box installation device further including a box-fitting mechanism, the box-fitting mechanism including a box-fitting frame; the bottom of the box-fitting frame is provided with a lid-opening cylinder, the lid-opening cylinder being connected to a suction cup.

[0015] The opening cylinder can extend or retract. When the opening cylinder extends, the suction cup approaches the packaging box until it contacts the box, and the suction cup adheres to the box. When the opening cylinder retracts, the suction cup pulls open the long side of the packaging box.

[0016] In a preferred embodiment of the present invention, the housing frame is provided with a plurality of suction cups; the suction cups connected to the housing frame and the suction cups connected to the opening cylinder are located on the same side of the housing frame.

[0017] Setting multiple suction cups on the box frame can enhance the adhesion to the long side lid of the packaging box.

[0018] In a preferred embodiment of the present invention, the packaging box installation device further includes a capping mechanism, which includes a positioning cylinder and a capping cylinder. The positioning cylinder is arranged along the height direction, and the capping cylinder is arranged along the horizontal direction. The positioning cylinder is used to position the packaging box on the roller line, and the capping cylinder is used to press down the short side of the box cover.

[0019] As the packaging box moves to the end of the roller conveyor, the positioning cylinder extends to position it. After detecting that the packaging box is in place, the capping cylinder extends downwards, and after the capping cylinder abuts against the short side caps of the packaging box, it continues to press down, folding the two short side caps of the packaging box inwards again.

[0020] In a preferred embodiment of the present invention, the capping mechanism further includes a support frame, the top of which is provided with the capping cylinder, and the side of which is provided with the positioning cylinder.

[0021] By setting capping cylinders and positioning cylinders at different positions on the support frame, the capping cylinders and positioning cylinders can work in different directions.

[0022] In a preferred embodiment of the present invention, the packaging box installation device further includes a box opening mechanism, which includes a box opening frame and a suction cup. A rotating shaft is installed on the side of the box opening frame, and the rotating shaft is connected to a box opening plate, which is connected to the suction cup.

[0023] One side of the box-opening frame is equipped with an opening plate and a rotating shaft. The opening plate rotates around the shaft, with a rotation angle of 0-90 degrees. When opening the box is required, the longer side of the opening plate forms a 90-degree angle with the shorter side; when opening the box is not required, the longer side and the shorter side of the opening plate are aligned. Suction cups on the opening plate are used to stabilize the three-dimensional shape of the packaging box.

[0024] In a preferred embodiment of the present invention, the unpacking mechanism further includes a push-rotating cylinder, with hinge seats connected to both ends of the push-rotating cylinder, and the hinge seats near the unpacking plate being connected to the unpacking plate.

[0025] The push-rotor cylinder is used to provide rotational power to the opening plate, so that the opening plate can rotate 0-90 degrees around the axis.

[0026] The beneficial effects of this invention are as follows:

[0027] This invention provides a folding mechanism including a platform with an arc-shaped portion and a flat portion, the arc-shaped portion being inclined towards the flat portion; a guide mechanism is provided near the flat portion, the guide mechanism including at least two guide rods, each guide rod including a bent portion, the end of the bent portion near the platform extending towards the adjacent bent portion; the platform is used to fold the short side lid of a packaging box, and the bent portion is used to fold the long side lid of the packaging box. The arc-shaped portion is inclined towards the flat portion and has a certain curvature, using the arc-shaped portion to drive the short side lid to rotate towards the flat portion, thereby folding the short side lid. After the arc-shaped portion folds the short side lid, the folding angle of the short side lid is less than 90 degrees, and then the flat portion presses down on the initially folded short side lid, making the folding angle of the short side lid 90 degrees. The bent portion of the guide rod extends from the end near the platform towards the adjacent bent portion, the bent portion being inclined, and the bent portion abuts against the long side lid of the packaging box, folding the long side lid inward. The aforementioned folding mechanism can fold the short and long side lids of the packaging box, facilitating automatic flipping of the packaging box in subsequent processes.

Detailed Implementation

[0038] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0039] Example 1

[0040] like Figure 1 As shown, this embodiment provides a folding mechanism 1, including a platform 11. The platform 11 includes an arcuate portion 111 and a flat portion 112. The arcuate portion 111 is inclined toward the flat portion 112. A guide mechanism 12 is provided near the flat portion 112. The guide mechanism 12 includes at least two guide rods 13. The guide rods 13 include bent portions 131. One end of the bent portion 131 near the platform 11 extends toward the adjacent bent portion 131. The platform 11 is used to fold the short side lid of the packaging box, and the bent portion 131 is used to fold the long side lid of the packaging box.

[0041] The arc-shaped portion 111 may be partly arc-shaped connected to the planar portion 112, with the rest being straight, or the entire arc-shaped portion 111 may be arc-shaped. In this embodiment, the partly arc-shaped connected to the planar portion 112 is taken as an example, with the rest being straight.

[0042] The part where the arc-shaped portion 111 connects to the flat portion 112 has a certain curvature. The end of the arc-shaped portion 111 away from the flat portion 112 is located below the flat portion 112, and this end extends in a direction close to the flat portion 112. The angle at the connection between the arc-shaped portion and the flat portion is greater than 90 degrees.

[0043] The flat portion 112 is longer, while the curved portion 111 is shorter. A robotic arm or robot operates the platform 11, causing the curved portion 111 of the platform 11 to abut against the short side lid of the packaging box. The short side lid has a certain degree of flexibility and is initially in a vertical position. The curved portion 111 drives the short side lid to rotate inward, thereby folding the short side lid. At this point, a crease is formed on the short side lid, but the folding angle is less than 90 degrees.

[0044] In this embodiment, the packaging box is used to house the indoor unit of an air conditioner, and it is empty during the processing steps. The curved part 111 initially folds the short side lids on both sides of the packaging box, and after creases are formed on the two short side lids, the flat part 112 presses down on the initially folded short side lids. Because the flat part 112 is relatively long and has a certain degree of flatness, the two short side lids can be folded at one time using the flat part 112, so that the folding angle of the two short side lids is 90 degrees.

[0045] A guide mechanism 12 is provided near the planar portion 112. The guide mechanism 12 includes multiple guide rods 13. In this embodiment, the guide mechanism 12 includes two guide rods 13. The bent portion 131 of one guide rod 13 extends from one end near the platform 11 towards the bent portion 131 of the other guide rod 13. The distance between the two guide rods 13 gradually decreases from the end closest to the platform 11 to the end farthest from the platform 11.

[0046] After platform 11 folds the short side lid of the packaging box, the robotic arm or robot-controlled guide rod 13 abuts against the long side lid of the packaging box. The long side lid has a certain degree of flexibility and is initially in a vertical position. The bent portion 131 of the guide rod 13 drives the long side lid to rotate inward, thereby folding the long side lid. Creases are formed on both long side lids of the packaging box, at which point the folding angle of the long side lids is less than 90 degrees. The process of folding the long side lids only needs to create creases to soften them; the specific angle is not limited here.

[0047] This embodiment provides a folding mechanism 1 including a platform 11, which includes an arc-shaped portion 111 and a flat portion 112. The arc-shaped portion 111 is inclined toward the flat portion 112. A guide mechanism 12 is provided near the flat portion 112, and the guide mechanism 12 includes at least two guide rods 13. Each guide rod 13 includes a bent portion 131, with one end of the bent portion 131 near the platform 11 extending toward the adjacent bent portion 131. The platform 11 is used to fold the short side lid of the packaging box, and the bent portion 131 is used to fold the long side lid of the packaging box. The arc-shaped portion 111 is inclined toward the flat portion 112 and has a certain curvature. Using the arc-shaped portion 111, the short side lid can be rotated toward the flat portion 112, thereby folding the short side lid. After the arc-shaped part 111 folds the short side lid, the folding angle of the short side lid is less than 90 degrees. Then, the flat part 112 presses down on the initially folded short side lid, so that the folding angle of the short side lid is 90 degrees. The bending part 131 of the guide rod 13 extends from the end near the platform 11 towards the adjacent bending part 131. The bending part 131 is inclined and presses against the long side lid of the packaging box, folding the long side lid inward. The above-mentioned folding mechanism 1 can fold the short side lid and the long side lid of the packaging box, which facilitates the automatic flipping of the packaging box in subsequent processes.

[0048] Example 2

[0049] like Figure 1 As shown, this embodiment provides a folding mechanism 1, including a platform 11. The platform 11 includes an arcuate portion 111 and a flat portion 112. The arcuate portion 111 is inclined toward the flat portion 112. A guide mechanism 12 is provided near the flat portion 112. The guide mechanism 12 includes at least two guide rods 13. The guide rods 13 include bent portions 131. One end of the bent portion 131 near the platform 11 extends toward the adjacent bent portion 131. The platform 11 is used to fold the short side lid of the packaging box, and the bent portion 131 is used to fold the long side lid of the packaging box.

[0050] The folding mechanism 1 also includes a shaping frame 14, which is connected to the arcuate portion 111 of the platform 11. The platform 11 and the guide mechanism 12 are both located on the top of the shaping frame 14, and the guide rod 13 is connected to the top of the shaping frame 14.

[0051] The guide rod 13 also includes a fixing part 132, which is connected to the end of the bending part 131 away from the platform 11, and the fixing part 132 is connected to the shaping frame 14.

[0052] The fixing part 132 is straight and is connected to the bending part 131. The connection between the fixing part 132 and the bending part 131 is arc-shaped. The length of the fixing part 132 can be greater than the length of the bending part 131, or it can be less than or equal to the length of the bending part 131.

[0053] The arc-shaped portion 111 is connected to the flat portion 112, and the height of the end of the arc-shaped portion 111 away from the flat portion 112 is less than the height of the flat portion 112. The end of the arc-shaped portion 111 away from the flat portion 112 is located below the flat portion 112, and this end extends towards the flat portion 112, with its height continuously increasing.

[0054] The robot controls the packaging box to slide on the folding mechanism 1, causing the short side lid of the packaging box to fold inward by 90 degrees, and creating a crease on the long side lid. The combined action of the arc-shaped part 111 and the flat part 112 of the platform 11, as well as the bending part 131 and the fixing part 132 of the guide rod 13, solves the problem of high difficulty in flipping and folding the box lid in subsequent processes.

[0055] The guide rod 13 of the folding mechanism 1 in this embodiment further includes a fixing part 132, which is connected to the end of the bending part 131 away from the platform 11 and is also connected to the shaping frame 14. The arc-shaped part 111 is connected to the flat part 112, and the height of the end of the arc-shaped part 111 away from the flat part 112 is less than the height of the flat part 112. The fixing part 132 can fix the bending part 131, improving its stability. The fact that the height of the end of the arc-shaped part 111 away from the flat part 112 is less than the height of the flat part 112 allows the arc-shaped part 111 to better drive the short side lid of the packaging box to rotate inward, causing a crease to form on the short side lid.

[0056] Example 3

[0057] like Figures 3-9As shown, this embodiment provides a packaging box installation device, including the folding mechanism 1 in embodiment 1 or 2. The packaging box installation device also includes a box-fitting mechanism 2, which includes a box-fitting frame 21. The bottom of the box-fitting frame 21 is provided with a lid-opening cylinder 22, and the lid-opening cylinder 22 is connected to a suction cup 5.

[0058] The profiles are spliced ​​together to form the box-fitting frame 21. Two opening cylinders 22 are installed at the bottom of the frame 21, each connected to a suction cup 5. The opening cylinders 22 can extend or retract. When an opening cylinder 22 extends, the suction cup 5 approaches the box until it contacts it, and the suction cup 5 adheres to the box. When an opening cylinder 22 retracts, the suction cup 5 pulls open the long side lid of the box, and then the robot is controlled to fit the box.

[0059] The housing frame 21 is provided with a plurality of suction cups 5; the suction cups 5 connected to the housing frame 21 and the suction cups 5 connected to the opening cylinder 22 are located on the same side of the housing frame 21.

[0060] In this embodiment, the carton frame 21 is equipped with four suction cups 5. Two suction cups 5 are located on the upper part of the carton frame 21, and two suction cups 5 are located on the lower part of the carton frame 21. The first suction cup 5 on the lower part of the carton frame 21 is located near the first lid-opening cylinder 22, and the second suction cup 5 is located near the second lid-opening cylinder 22. The multiple suction cups 5 on the carton frame 21 enhance the suction force on the long side lid of the packaging carton.

[0061] The four suction cups 5 connected to the box frame 21 and the four suction cups 5 connected to the two opening cylinders 22 are all located on the same side, that is, the side of the box frame 21 closest to the packaging box.

[0062] The packaging box installation device also includes a capping mechanism 3, which includes a positioning cylinder 31 and a capping cylinder 32. The positioning cylinder 31 is arranged along the height direction, and the capping cylinder 32 is arranged along the horizontal direction. The positioning cylinder 31 is used to position the packaging box on the roller line 6, and the capping cylinder 32 is used to press down the short side of the box cover.

[0063] The capping mechanism 3 also includes a support frame 33, the top of which is provided with the capping cylinder 32, and the side of which is provided with the positioning cylinder 31.

[0064] The support frame 33 is fixed above the roller line 6. A positioning cylinder 31 is provided on the side of the support frame 33. The positioning cylinder 31 extends to position the packaged box in place. The capping cylinder 32 is fixed on the top of the support frame and presses down the short side cap of the positioned packaged box.

[0065] After folding the short and long side lids of the packaging box, the box is placed on roller line 6. The box lids will spring back slightly, and because creases have already formed, subsequent lid folding will be very stable. As the packaging box moves to the end of roller line 6, positioning cylinder 31 extends to position it. After detecting that the packaging box is in place, pressing cylinder 32 extends downwards, abutting against the short side lids of the packaging box and continuing to press down, folding the two short side lids of the packaging box inwards again.

[0066] After the capping cylinder 32 folds the two short side lids of the packaging box, the box-fitting mechanism 2 picks up the packaging box from the roller line 6 through robot action. At the same time, the capping cylinder 22 extends, and the vacuum suction cup 5 on the capping cylinder 22 adsorbs the long side lid. Then the capping cylinder 22 retracts to pull open the long side lid. Finally, the packaging box is fitted onto the air conditioner indoor unit through robot action.

[0067] This embodiment provides a packaging box installation device, including a folding mechanism 1 and a box-fitting mechanism 2. The box-fitting mechanism 2 includes a box-fitting frame 21. A lid-opening cylinder 22 is provided at the bottom of the box-fitting frame 21, and the lid-opening cylinder 22 is connected to a suction cup 5. The box-fitting frame 21 is provided with multiple suction cups 5; the suction cups 5 connected to the box-fitting frame 21 and the suction cups 5 connected to the lid-opening cylinder 22 are located on the same side of the box-fitting frame 21. After the lid-pressing cylinder 32 folds the two short side lids of the packaging box, the box-fitting mechanism 2 picks up the packaging box from the roller conveyor 6 through robot action. Simultaneously, the lid-opening cylinder 22 extends, and the vacuum suction cup 5 on the lid-opening cylinder 22 adsorbs the long side lid. Then, the lid-opening cylinder 22 retracts, pulling open the long side lid. Finally, the packaging box is fitted onto the air conditioner indoor unit through robot action.

[0068] Example 4

[0069] like Figures 3-9 As shown, this embodiment provides a packaging box installation device, including the folding mechanism 1 of embodiment 1 or 2. The packaging box installation device also includes a box-fitting mechanism 2, which includes a box-fitting frame 21. The bottom of the box-fitting frame 21 is provided with a lid-opening cylinder 22, and the lid-opening cylinder 22 is connected to a suction cup 5.

[0070] The housing frame 21 is provided with a plurality of suction cups 5; the suction cups 5 connected to the housing frame 21 and the suction cups 5 connected to the opening cylinder 22 are located on the same side of the housing frame 21.

[0071] The packaging box installation device also includes a capping mechanism 3, which includes a positioning cylinder 31 and a capping cylinder 32. The positioning cylinder 31 is arranged along the height direction, and the capping cylinder 32 is arranged along the horizontal direction. The positioning cylinder 31 is used to position the packaging box on the roller line 6, and the capping cylinder 32 is used to press down the short side of the box cover.

[0072] The capping mechanism 3 also includes a support frame 33, the top of which is provided with the capping cylinder 32, and the side of which is provided with the positioning cylinder 31.

[0073] The packaging box installation device also includes an opening mechanism 4, which includes an opening frame 41 and a suction cup 5. A rotating shaft 42 is installed on the side of the opening frame 41, and the rotating shaft 42 is connected to an opening plate 43, which is connected to the suction cup 5.

[0074] The unpacking mechanism 4 also includes a push-rotating cylinder 44, with hinge seats 45 connected to both ends of the push-rotating cylinder 44. The hinge seats 45 near the unpacking plate 43 are connected to the unpacking plate 43.

[0075] The function of the unpacking mechanism 4 is to remove the air conditioner indoor unit packaging box from the material handling position and then unfold the two-dimensional flat packaging box into a three-dimensional structure. A tooling cart containing the packaging boxes will be placed next to the robot, and the robot controls the unpacking mechanism 4 to pick up the materials from the tooling cart.

[0076] A square steel tube is welded to form the opening frame 41 of the box-opening mechanism 4. Four retractable suction cups 5 are fixed on the opening frame 41. Each suction cup 5 includes a suction rod 51, a spring 52, a sleeve 53, and a plate body. The first end of the suction rod 51 is connected to the sleeve 53, the spring 52 is sleeved on the suction rod 51, and the second end of the suction rod 51 is connected to the plate body. By fixing the sleeve 53, the suction cup 5 rod can extend and retract within the sleeve 53. The extension and retraction function is to balance the errors caused by uneven thickness of the packaging box and inaccurate sensor positioning when removing the box.

[0077] An opening plate 43 and a rotating shaft 42 are mounted on one side of the box-opening frame 41. The opening plate 43 rotates around the rotating shaft 42, with a rotation angle of 0-90 degrees. The rotational power is provided by a push-rotation cylinder 44, both ends of which are fixed by hinge seats 45. The first hinge seat 45 is connected to the opening plate 43, and the second hinge seat 45 is connected to the box-opening frame 41. Two vacuum suction cups 5 are fixed on the opening plate 43 to stabilize the three-dimensional shape of the packaging box.

[0078] The shorter side of the opening plate 43 is connected to the rotating shaft 42, and the longer side of the opening plate 43 is connected to the shorter side. The output shaft of the push-rotating cylinder 44 is connected to the first hinge seat 45, which is screwed to the shorter side of the opening plate 43. When opening the box is required, the opening plate 43 is L-shaped, with the longer side and the shorter side forming a 90-degree angle; when opening the box is not required, the opening plate 43 is straight, with the longer side and the shorter side on the same straight line.

[0079] The two suction cups 5 on the opening plate 43 are located on the side away from the rotating shaft 42. The opening frame 41 has a total of 4 suction cups 5, of which 2 suction cups 5 are located on the side of the opening frame 41 closer to the rotating shaft 42, and the other 2 suction cups 5 are located on the side of the opening frame 41 away from the rotating shaft 42.

[0080] The unpacking mechanism 4 uses a robot to pick up a package from the material handling position. After picking it up, the package is unfolded into a three-dimensional structure. Then, the robot slides the package on the folding mechanism 1, causing the short side lid of the package to fold inward by 90 degrees, and creating a crease on the long side lid. After folding, the package is placed on the roller conveyor 6, and the unpacking plate 43 of the unpacking mechanism 4 opens. At this time, the short side lid and the long side lid of the package will spring back a certain angle. Because a crease has already been created, the folding of the short side lid by the capping mechanism 3 will be very stable.

[0081] As the packaging box moves to the end of roller conveyor 6, positioning cylinder 31 extends to position it, and capping cylinder 32 extends downward, folding the two short side lids of the packaging box inward again. After folding the two short side lids, the box-fitting mechanism 2 picks up the packaging box from roller conveyor 6 through robot action. At the same time, capping cylinder 22 extends, and vacuum suction cup 5 on capping cylinder 22 adsorbs the long side lid. Then capping cylinder 22 retracts, pulling open the long side lid. Finally, the packaging box is fitted onto the air conditioner indoor unit through robot action.

[0082] The packaging box installation device in this embodiment consists of a folding mechanism 1, a box-fitting mechanism 2, a lid-pressing mechanism 3, and a box-opening mechanism 4. It adopts a modular design, offering advantages such as high versatility and ease of maintenance. Based on the folding mechanism 1, box-fitting mechanism 2, lid-pressing mechanism 3, and box-opening mechanism 4, it realizes the actions of picking up, opening, closing, and fitting the packaging box, enabling multiple operations on the packaging box and demonstrating a high degree of integration. Compared to the traditional box-fitting method, the packaging box installation device in this embodiment adds a lid-folding function, solving the problem of high difficulty in flipping and folding the box in subsequent processes.

[0083] Traditional air conditioner indoor unit installation and packaging process requires manual intervention, is cumbersome, and carries a high risk of danger due to the transfer and placement of packaging boxes. Using the packaging box installation device of this embodiment, 450 air conditioner indoor unit packaging boxes can be installed per hour, compared to only 250 per hour with manual operation. Therefore, this packaging box installation device can increase production by at least 50%, thereby shortening the production cycle.

[0084] In addition, the packaging box installation device in this embodiment only requires the operation of the control mechanism to complete the automated operation, without the need for complicated manual operation. Therefore, it is simple and easy to operate, requires low personnel skills, and has high safety, eliminating the safety hazards caused by manual operation.

[0085] The packaging box installation device in this embodiment also includes an opening mechanism 4, which includes an opening frame 41 with suction cups 5. A rotating shaft 42 is mounted on the side of the opening frame 41, and the rotating shaft 42 is connected to an opening plate 43, which is connected to the suction cups 5. The opening mechanism 4 also includes a push-rotation cylinder 44, with hinge seats 45 connected to both ends. The hinge seats 45 near the opening plate 43 are connected to the opening plate 43. The function of the opening mechanism 4 is to remove the air conditioner indoor unit packaging box from the material handling position and then unfold the two-dimensional flat packaging box into a three-dimensional structure. A tooling cart containing the packaging box is placed next to the robot, and the robot controls the opening mechanism 4 to retrieve the material from the tooling cart. Two vacuum suction cups 5 on the opening plate 43 are used to stabilize the three-dimensional packaging box.
