In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0053] The embodiment of the invention discloses a cartoning mechanism and a cartoning production line.

[0054] Reference Figures 1 to 3 The box loading mechanism includes a carrier 1, a loading rack 2, a support assembly 3 and a push assembly 4. The carrier 1 has a loading station for placing a packaging box 10; the loading rack 2 is arranged corresponding to the loading station; the support assembly 3 is arranged on the loading rack 2 and is used to carry the product 20, and the support assembly 3 can partially extend into the opening of the packaging box 10 and abut against the inner wall of the packaging box 10 to open the packaging box 10; the push assembly 4 is arranged on the loading rack 2 and can partially extend into the support assembly 3 to push the product 20 into the packaging box 10.

[0055] Specifically, the carrier 1 is in the shape of a long strip and fixed on the ground. The carrier 1 is close to the loading mechanism, which can continuously transport multiple packaging boxes 10 to a position close to the carrier 1, and then transport them to the loading station of the carrier 1 through a manipulator or a transport structure, etc., and a suction cup or other structure can be set on the loading station to fix the packaging box 10. Multiple loading stations can be arranged at intervals along the length direction of the carrier 1, and each loading station is correspondingly provided with a loading rack 2.

[0056] The extension direction of the loading rack 2 is perpendicular to the carrier rack 1. A support assembly 3 is arranged on the top wall of the loading rack 2. One side of the support assembly 3 is used to carry the product 20, and the other side can go deep into the packaging box 10. The product 20 can be a base containing multiple cosmetic contact lenses, and the instruction manual can also be placed on the base. The support assembly 3 abuts against the inner wall of the packaging box 10, thereby slightly expanding the opening of the packaging box 10 from the inside to the outside. The push assembly 4 is arranged on the side of the loading rack 2 away from the carrier rack 1, and its push end can extend into the support assembly 3 to push the product 20 into the packaging box 10.

[0057] By setting up the supporting rack 1 and the loading rack 2, the produced packaging box 10 can be placed on the loading station, and the product 20 can be placed on the opening component 3. The opening of the packaging box 10 is opened by the opening component 3, and the pushing component 4 is started. The pushing component 4 pushes the product 20 into the packaging box 10, and the opening component 3 leaves the packaging box 10. The packaging box 10 containing the product 20 is then transported to the next station, and the new packaging box 10 is placed on the loading station. The above steps are repeated to realize the boxing operation of batch products 20. Therefore, when the cartoning mechanism is in use, the opening of the packaging box 10 can be stretched open so that the opening of the packaging box 10 is larger than the size of the product 20, so that the product 20 can be accurately delivered into the packaging box 10. During the delivery process, the product 20 is pushed by the pushing assembly 4 to avoid grabbing and clamping the product 20, thereby effectively reducing the possibility of damaging and contaminating the product 20, ensuring that the sanitary conditions of the product 20 can meet the use requirements, and effectively reducing the possibility of affecting the normal use of the product 20.

[0058] Optionally, the opening support assembly 3 includes a support frame 31. The support frame 31 is slidably connected to the loading rack 2 in a direction close to or away from the loading station, and a plurality of rotating rods 32 are rotatably connected to the support frame 31, and a support piece 33 is fixedly provided on each rotating rod 32, and the side of the support piece 33 away from the rotating rod 32 can extend into the opening of the packaging box 10, and each rotating rod 32 is provided with an elastic connecting member 34, and the other end of the elastic connecting member 34 is fixedly connected to the loading rack 2, and the elastic connecting member 34 is used to drive the support piece 33 to rotate through the rotating rod 32 when the support piece 33 extends into the packaging box 10, so that the support piece 33 is pressed against the inner wall of the packaging box 10.

[0059] Specifically, the packaging box 10 is a rectangular parallelepiped structure, and four sealing sheets are arranged around the opening of the packaging box 10. When the four sealing sheets are unfolded, the product 20 can be put into the packaging box 10, and when the four sealing sheets overlap each other to the opening, the packaging box 10 can be closed. The support frame 31 is a rectangular ring structure, and a plurality of rotating rods 32 are rotatably connected to the support frame 31, and one end of the rotating rod 32 extends out of the support frame 31. The plurality of rotating rods 32 include two longitudinal rotating rods 32 and two transverse rotating rods 32, the two longitudinal rotating rods 32 are respectively located on the left and right sides of the support frame 31, and the two transverse rotating rods 32 are respectively located on the upper and lower sides of the support frame 31. The support piece 33 can be made of an elastic metal material and is L-shaped. A mounting notch is provided on the rotating rod 32. The bent section of the support piece 33 fits in the mounting notch. A plurality of threaded holes are provided in the mounting notch. The support piece 33 is provided with through holes corresponding to the threaded holes. A bolt is provided in each set of through holes and threaded holes to fix the support piece 33 on the supporting rod. The end of the support piece 33 away from the rotating rod 32 extends toward the loading station.

[0060] An elastic connector 34 is provided at one end of the rotating rod 32 extending out of the support frame 31. The elastic connector 34 can be directly connected to the side wall of the rotating rod 32, or can be connected to the end face of the rotating rod 32 through other structures, and the other end of the elastic connector 34 is fixedly connected to the structure on the loading rack 2, so that when the support frame 31 slides, the elastic connector 34 will produce elastic deformation and use elastic force to pull the rotating rod 32 to rotate, at which time the multiple support pieces 33 can move away from each other and gradually unfold, and the unfolded support pieces 33 can be pressed against the inner wall of the packaging box 10. The elastic connector 34 can be a spring, or a structure such as an elastic rod, which is not limited in the present invention.

[0061] When the opening of the packaging box 10 needs to be opened, the support frame 31 moves toward the direction close to the packaging box 10, so that the support piece 33 is inserted into the opening of the packaging box 10. As the support frame 31 moves, the elastic connector 34 will be deformed and pull the rotating rod 32 to move, so that the multiple support pieces 33 are separated from each other. During the separation process, the support pieces 33 can be pressed against the inner wall of the packaging box 10 to smoothly open the opening of the packaging box 10. After the product 20 is loaded, during the reset process of the support frame 31, the deformation amplitude of the elastic connector 34 is reduced, and the elastic force generated is reduced, so the pulling force on the rotating rod 32 is reduced, and the squeezing force between the opening of the packaging box 10 and the support piece 33 remains unchanged, so that the support piece 33 is squeezed to drive the rotating rod 32 to reset. When the support piece 33 is separated from the packaging box 10, it is reset under the action of the elastic connector 34, so as to smoothly open the opening of the next packaging box 10.

[0062] Optionally, the rotating rod 32 has a connecting piece 321 extending in the radial direction, and the elastic connecting member 34 is disposed at one end of the connecting piece 321 away from the rotating rod 32 .

[0063] Specifically, a mounting opening is opened on the end face of the rotating rod 32, and the connecting piece 321 is partially embedded in the mounting opening. The two can be fixed together by interference fit, welding, bonding, bolt connection, etc. A hanging hole is opened at the end of the connecting piece 321 away from the rotating rod 32, and the elastic connecting piece 34 can be hooked and fixed with the hanging hole.

[0064] By providing the connecting piece 321 , when the elastic connecting member 34 is deformed, its elastic force can be directly applied to one end of the connecting piece 321 , thereby driving the other end of the connecting piece 321 to rotate, and the other end of the connecting piece 321 can smoothly drive the rotating rod 32 to rotate.

[0065] Optionally, the cross-sectional area of ​​the support piece 33 decreases from the side close to the support frame 31 to the side close to the loading station.

[0066] Specifically, the cross-sectional area of ​​the support piece 33 mainly refers to the area facing the inner wall of the inner container, and the cross-sectional area is decreasing so that the size of the support piece 33 is smaller than the size of the packaging box 10, so that the support piece 33 can be smoothly inserted into the packaging box 10. The corners of the support piece 33 are all provided with rounded corners, which can reduce the sharpness of the tip and edge of the support piece 33, and reduce the damage to the packaging box 10 caused by the support piece 33 when it is pressed against the packaging box 10.

[0067] Optionally, the opening assembly 3 further includes a driving screw 35 and an opening driving member 36. The driving screw 35 is rotatably connected to the loading rack 2 and is threadedly connected to the support frame 31; the opening driving member 36 is disposed on the loading rack 2 and connected to the driving screw 35 to drive the driving screw 35 to rotate.

[0068] Specifically, a driving screw 35 is rotatably connected to the upper side of the loading rack 2, and the driving screw 35 extends along the length direction of the loading rack 2. A connecting seat 37 is fixedly provided on the support frame 31, and the driving screw 35 is passed through the connecting seat 37 and is threadedly connected to the connecting seat 37. The opening drive member 36 can be a servo motor, and its output end is coaxially fixedly connected to the driving screw 35 to drive the driving screw 35 to rotate.

[0069] By setting the driving screw 35 and the support opening driving member 36, when the support frame 31 needs to be moved, the support opening driving member 36 is started to drive the driving screw 35 to rotate, and the driving screw 35 cooperates with the connecting seat 37 to drive the support frame 31 to gradually approach the packaging box 10.

[0070] Optionally, the support assembly 3 further comprises a material rack 38 . The material rack 38 is arranged at a side of the support frame 31 away from the loading station and has a carrying space 381 for carrying the product 20 , and the bottom wall of the carrying space 381 is flush with the inner lower wall of the support frame 31 .

[0071] Specifically, a material storage rack 38 is fixedly arranged on one side of the support frame 31 away from the loading station, and the fixing method can be integrally formed, or can be welded, bonded, or bolted, etc. The cross section of the material storage rack 38 is U-shaped, and a bearing space 381 for placing the product 20 is formed inside the bearing space 381, and the bottom wall of the bearing space 381 is flush with the inner lower wall of the support frame 31, that is, the two are located in the same horizontal plane, so that the product 20 can pass through the support frame 31 smoothly.

[0072] The carrying space 381 can be formed by the concave middle part of the plate-like structure of the material frame 38, so that the material frame 38 is an integrated structure as a whole, or two limit bars can be fixed on the plate-like structure to form the carrying space 381. The present invention does not limit the specific structure of the material frame 38. The width of the opposite side walls of the carrying space 381 is equal to the width of the product 20, so that when the product 20 is placed in the carrying space 381, the product 20 and the side of the carrying frame can be fitted, and the two can slide relative to each other.

[0073] By setting a carrying frame on the side of the support frame 31 to carry the product 20, after the support piece 33 opens the opening of the packaging box 10, the support frame 31 will be very close to the opening of the packaging box 10. At this time, when the product 20 is pushed to move, the product 20 can slide in the carrying space 381 and pass through the support frame 31 to enter the interior of the packaging box 10.

[0074] In this embodiment, in order to arrange each structure more rationally in space, the connection seat 37 is fixed on the bottom wall of the material container 38, and the support frame 31 is driven to move synchronously by driving the material container 38. The material container 38 and the support frame 31 can be detachably connected by bolt connection or clamping, so that the material container 38 of different sizes can be replaced according to different products 20.

[0075] Optionally, the box loading mechanism further includes a cover plate 5. The cover plate 5 is disposed above the product 20 and at least partially corresponds to the product 20, and the gap between the bottom wall of the cover plate 5 and the product 20 is smaller than the gap between the product 20 and the inner top wall of the packaging box 10.

[0076] Specifically, the cover plate 5 can be directly arranged in the bearing space 381 of the material storage rack 38, and a certain gap is maintained between the cover plate 5 and the product 20 to prevent the product 20 from rubbing against the cover plate 5 during the sliding process, and the gap between the cover plate 5 and the product 20 is smaller than the gap between the product 20 and the top wall of the packaging box 10, so that when the product 20 is warped during the pushing process, the cover plate 5 can form a hard limit on the warped part to prevent the warping amplitude of the product 20 from exceeding the size of the packaging box 10, thereby ensuring that the product 20 can be smoothly loaded into the packaging box 10. A lubricating film or other structure can be provided on the bottom wall of the cover plate 5 to ensure that it does not cause any damage or contamination to the product 20.

[0077] Optionally, the cover plate 5 is slidably connected to the loading rack 2 ; the box loading mechanism further comprises a material pressing driving member 51 . The material pressing driving member 51 is disposed on the loading rack 2 and connected to the cover plate 5 to drive the cover plate 5 to insert into or leave the support opening assembly 3 .

[0078] Specifically, the material pressing drive member 51 can be a cylinder, which is fixed on the side of the loading rack 2. A connecting plate 52 is arranged on the piston rod of the cylinder. The connecting plate 52 extends in the vertical direction. An extension plate 53 is fixedly arranged on the top wall of the connecting plate 52. The extension plate 53 extends in the horizontal direction. The bottom wall of the extension plate 53 is fixedly connected to the top wall of the cover plate 5.

[0079] By setting up the pressing drive 51, when the cover plate 5 is needed to cover the product 20, the pressing drive 51 is started, and the cover plate 5 is driven to move into the carrying space 381 through the connecting plate 52 and the extension plate 53. When the product 20 is pushed into the packaging box 10, the cover plate 5 can be driven to leave the carrying space 381, so as to facilitate the placement of a new product 20 in the carrying space 381.

[0080] Optionally, the pusher assembly 4 includes a pusher plate 41 and a pusher drive 42. The pusher plate 41 is slidably connected to the loading rack 2 and is located on a side of the product 20 away from the support assembly 3; the pusher drive 42 is connected to the pusher plate 41 to drive the pusher plate 41 to abut against the product 20.

[0081] Specifically, the pushing drive member 42 can adopt a linear motor module, which is fixed on the top wall of the loading rack 2, and the pushing plate 41 is fixed on the mover. The pushing plate 41 can be inserted into the carrying space 381. The width of the pushing plate 41 is smaller than the width of the carrying space 381, so that the pushing plate 41 can be smoothly inserted into the carrying space 381, and a pushing strip 43 can be set on the side of the pushing plate 41 close to the product 20. The length of the pushing strip 43 is greater than the width of the pushing plate 41, and the two ends of the pushing strip 43 can maintain a certain gap with the inner side wall of the carrying space 381 to ensure that the pushing strip 43 will not be stuck with the material frame 38, and the pushing strip 43 can form a sufficient contact area with the product 20, thereby effectively pushing the product 20 to slide in the carrying space 381.

[0082] Optionally, the box loading mechanism further includes a positioning block 6 and a positioning drive 7. The positioning block 6 is slidably connected to the carrier 1, and one side of the positioning block 6 can extend into the side of the packaging box 10 away from the opening assembly 3; the positioning drive 7 is disposed on the carrier 1 and connected to the positioning block 6 to drive the positioning block 6 to approach or move away from the packaging box 10.

[0083] Specifically, the positioning drive member 7 can be a cylinder, whose cylinder body is fixed on the carrier frame 1, and the positioning block 6 is L-shaped, with its lower end fixed on the piston rod of the cylinder and the upper end capable of being inserted into the packaging box 10, and the upper end of the positioning block 6 can also be provided with an insertion slope so that the cross-sectional area of ​​the end inserted into the packaging box 10 is smaller, so as to facilitate smooth insertion into the packaging box 10.

[0084] By setting the positioning block 6 and the positioning drive 7, before the packaging box 10 is placed on the loading station, the positioning drive 7 can drive the positioning block 6 away from the loading station. When the packaging box 10 is placed on the loading station, the positioning drive 7 is reset, and the positioning block 6 can be inserted into the packaging box 10 to preliminarily position the packaging box 10 on the loading tooling. At the same time, in the process of loading the product 20 into the product 20 box, the positioning block 6 can also play a stopping effect to reduce the product 20 from escaping from the other side of the packaging box 10.

[0085] Reference Figure 4 The cartoning production line includes a grabbing mechanism 8 and the cartoning mechanism in the above embodiment. The grabbing mechanism 8 is used to grab the folded packaging box 10 to the loading station, and grab the cartoned packaging box 10 at the loading station to the next station.

[0086] During use of the cartoning production line, the cartoning mechanism can quickly and accurately deliver the product 20 into the packaging box 10, and the gripping mechanism 8 can quickly transport the completed packaging box 10 to the next station, and at the same time deliver the new packaging box 10 to the loading station, so that the entire cartoning operation can be completed automatically, effectively improving the overall degree of automation, thereby effectively improving the efficiency of the cartoning operation for thin and light products 20 such as cosmetic contact lenses.
