[0055] Specifically, the carrying frame 1 is in a long strip shape and is fixed on the ground, and the carrying frame 1 abuts against a feeding mechanism, the feeding mechanism can continuously convey a plurality of packaging boxes 10 to a position close to the carrying frame 1, and then a mechanical hand or a carrying structure or the like is used to carry the packaging boxes 10 to the loading stations of the carrying frame 1, and a suction cup or the like structure can be arranged on the loading station to fix the packaging boxes 10. A plurality of loading stations can be arranged at intervals along the length direction of the carrying frame 1, and each loading station is correspondingly provided with a loading frame 2.

[0056] The extension direction of the loading frame 2 is perpendicular to the bearing frame 1, and the supporting and opening assembly 3 is arranged on the top wall of the loading frame 2, one side of the supporting and opening assembly 3 is used to bear the product 20, and the other side can be inserted into the packaging box 10, and the product 20 can be a base containing multiple beauty lenses, and a manual can also be placed on the base. The supporting and opening assembly 3 abuts against the inner wall of the packaging box 10, so as to slightly expand the opening of the packaging box 10 from the inside to the outside. The pushing assembly 4 is arranged on the side of the loading frame 2 away from the bearing frame 1, and the pushing end of the pushing assembly 4 can be inserted into the supporting and opening assembly 3 to push the product 20 into the packaging box 10.

[0057] By arranging the bearing frame 1 and the loading frame 2, the produced packaging box 10 can be placed on the loading station, the product 20 is placed on the supporting and opening assembly 3, the opening of the packaging box 10 is opened by the supporting and opening assembly 3, the pushing assembly 4 is started, the product 20 is pushed into the packaging box 10 by the pushing assembly 4, the supporting and opening assembly 3 leaves the packaging box 10, the packaging box 10 containing the product 20 is transported to the next station, and the new packaging box 10 is placed on the loading station, and the above steps are repeated to realize the boxing operation of the batch product 20. Therefore, when the boxing mechanism is used, the opening of the packaging box 10 can be opened, so that the opening of the packaging box 10 is larger than the size of the product 20, and the product 20 can be accurately sent into the packaging box 10, and the product 20 is pushed by the pushing assembly 4 during the sending process, avoiding 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 supporting and opening assembly 3 comprises a supporting frame 31. The supporting frame 31 is slidingly connected to the loading frame 2 in the direction close to or away from the loading station, a plurality of rotating rods 32 are rotatably connected to the supporting frame 31, a supporting piece 33 is fixedly arranged on each rotating rod 32, the side of the supporting piece 33 away from the rotating rod 32 can be inserted into the opening of the packaging box 10, and an elastic connecting piece 34 is arranged on each rotating rod 32. The other end of the elastic connecting piece 34 is fixedly connected to the loading frame 2, and the elastic connecting piece 34 is used to drive the supporting piece 33 to rotate through the rotating rod 32 when the supporting piece 33 is inserted into the packaging box 10, so that the supporting piece 33 abuts against the inner wall of the packaging box 10.

[0059] Specifically, the packaging box 10 is a cuboid structure, four sealing pieces are arranged around the opening of the packaging box 10, when the four sealing pieces are unfolded, the product 20 can be sent into the packaging box 10, and when the four sealing pieces overlap each other at the opening, the packaging box 10 can be closed. The support frame 31 is a rectangular ring structure, 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 a thin plate of a metal material with elasticity and has an L shape, an installation gap is arranged on the rotating rod 32, the bent section of the support piece 33 is fitted into the installation gap, a plurality of threaded holes are arranged in the installation gap, a through hole corresponding to the threaded hole is arranged on the support piece 33, and a bolt is arranged in each group of the through hole and the threaded hole to fix the support piece 33 on the support rod. The end of the support piece 33 away from the rotating rod 32 extends towards the loading station.

[0060] An elastic connecting piece 34 is arranged at the end of the rotating rod 32 extending out of the support frame 31, the elastic connecting piece 34 can be directly connected with the side wall of the rotating rod 32, or can be connected with the end face of the rotating rod 32 through other structures, and the other end of the elastic connecting piece 34 is fixedly connected with the structure on the loading frame 2, so that in the sliding process of the support frame 31, the elastic connecting piece 34 will be elastically deformed to pull the rotating rod 32 to rotate by the elastic force, at this time, the plurality of support pieces 33 can be gradually unfolded away from each other, and the unfolded support pieces 33 can abut against the inner wall of the packaging box 10. The elastic connecting piece 34 can be a spring or an elastic rod, and the present application does not make any limitation on this.

[0061] When it is necessary to open the opening of the packaging box 10, the support frame 31 moves towards the packaging box 10, so that the support piece 33 is inserted into the opening of the packaging box 10, with the movement of the support frame 31, the elastic connecting piece 34 will be deformed to pull the rotating rod 32 to move, and the plurality of support pieces 33 are separated from each other, and in the separation process, the support piece 33 can abut against the inner wall of the packaging box 10 to smoothly open the opening of the packaging box 10. When the product 20 is loaded, in the resetting process of the support frame 31, the deformation amplitude of the elastic connecting piece 34 decreases, the elastic force generated by the elastic connecting piece 34 decreases, the pulling force on the rotating rod 32 decreases, the pressing force between the opening of the packaging box 10 and the support piece 33 does not change, so that the support piece 33 is pressed to drive the rotating rod 32 to reset, and when the support piece 33 is separated from the packaging box 10, the support piece 33 is reset under the action of the elastic connecting piece 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 piece 34 is arranged at the end of the connecting piece 321 away from the rotating rod 32.

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

[0064] By setting the connecting piece 321, when the elastic connecting piece 34 deforms, the elastic force thereof can be directly applied to one end of the connecting piece 321, thereby driving the other end of the connecting piece 321 to rotate. 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 supporting piece 33 decreases from the side close to the supporting frame 31 to the side close to the loading station.

[0066] Specifically, the cross-sectional area of the supporting piece 33 mainly refers to the area toward the inner wall of the inner container. The cross-sectional area decreases so that the size of the supporting piece 33 is smaller than that of the packaging box 10, so that the supporting piece 33 can be smoothly inserted into the packaging box 10. The corners of the supporting piece 33 are all provided with rounded corner treatment, which can reduce the sharpness of the sharp ends and edges of the supporting piece 33, and reduce the damage to the packaging box 10 when the supporting piece 33 abuts against the packaging box 10.

[0067] Optionally, the supporting opening assembly 3 further comprises a driving screw 35 and a supporting opening driving piece 36. The driving screw 35 is rotationally connected to the loading rack 2 and is in threaded connection with the supporting frame 31. The supporting opening driving piece 36 is arranged on the loading rack 2 and is connected with the driving screw 35 to drive the driving screw 35 to rotate.

[0068] Specifically, the driving screw 35 is rotationally connected to the upper side of the loading rack 2 and extends along the length direction of the loading rack 2. A connecting seat 37 is fixedly arranged on the supporting frame 31. The driving screw 35 penetrates through the connecting seat 37 and is in threaded connection with the connecting seat 37. The supporting opening driving piece 36 can be a servo motor. The output end thereof is coaxially fixedly connected with the driving screw 35 to drive the driving screw 35 to rotate.

[0069] By setting the driving screw 35 and the supporting opening driving piece 36, when it is needed to move the supporting frame 31, the supporting opening driving piece 36 is started to drive the driving screw 35 to rotate. The supporting frame 31 can be gradually moved close to the packaging box 10 through the cooperation of the driving screw 35 and the connecting seat 37.

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

[0071] Specifically, the material containing frame 38 is fixedly arranged on the side of the support frame 31 away from the loading station, and the fixing manner can be integrally formed, welded, bonded, bolted or the like. The material containing frame 38 has a U-shaped cross section, and the inner side of the material containing frame 38 forms a bearing space 381 for placing the product 20. The bottom wall of the bearing space 381 is flush with the inner low wall of the support frame 31, i.e., the bottom wall of the bearing space 381 and the inner low wall of the support frame 31 are located in the same horizontal plane, so that the product 20 can smoothly pass through the support frame 31.

[0072] The bearing space 381 can be formed by concave down of the middle part of the plate structure of the material containing frame 38, so that the material containing frame 38 has an integrated structure as a whole, or two limiting strips can be fixed on the plate structure to form the bearing space 381. The specific structure of the material containing frame 38 is not limited in the present application. The width of the opposite side walls of the bearing space 381 is equal to the width of the product 20, so that when the product 20 is placed in the bearing space 381, the product 20 and the side wall of the bearing frame can form a fit, and the product 20 and the side wall of the bearing frame can slide relative to each other.

[0073] By arranging the bearing frame on the side of the support frame 31 to bear the product 20, the support frame 31 will be very close to the opening of the packaging box 10 after the support piece 33 opens the opening of the packaging box 10. At this time, the product 20 can be moved in the bearing space 381 and enter the packaging box 10 after passing through the support frame 31.

[0074] In the present embodiment, in order to more reasonably arrange the structures in space, the above-mentioned connecting seat 37 is fixed on the bottom wall of the material containing frame 38, and the material containing frame 38 is driven to move to drive the support frame 31 to move synchronously. The material containing frame 38 and the support frame 31 can be connected in a detachable manner such as bolt connection or clamping, so as to replace the material containing frame 38 of different sizes according to different products 20.

[0075] Optionally, the box loading mechanism further comprises a cover plate 5. The cover plate 5 is arranged above the product 20 and at least partially corresponds to the product 20. 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 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 containing frame 38, and a gap is maintained between the cover plate 5 and the product 20 to avoid friction between the product 20 and the cover plate 5 during sliding. 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 pushed up, the cover plate 5 can form a hard limit for the upturned part to avoid the upturned amplitude of the product 20 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 the like structure can be arranged on the bottom wall of the cover plate 5 to ensure that the cover plate 5 does not cause any damage or pollution to the product 20.

[0077] Optionally, the cover plate 5 is slidingly connected to the loading frame 2, and the loading mechanism further comprises a pressing driving member 51. The pressing driving member 51 is arranged on the loading frame 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 pressing driving member 51 can be a pneumatic cylinder fixed on the side of the loading frame 2, and a connecting plate 52 is arranged on the piston rod of the pneumatic cylinder, the connecting plate 52 extends in the vertical direction, and 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, and the bottom wall of the extension plate 53 is fixedly connected to the top wall of the cover plate 5.

[0079] By arranging the pressing driving member 51, when the cover plate 5 is needed to cover the product 20, the pressing driving member 51 is started to drive the cover plate 5 to move into the bearing space 381 through the connecting plate 52 and the extension plate 53, and after the product 20 is pushed into the packaging box 10, the cover plate 5 can be driven to leave the bearing space 381 to facilitate the placement of new products 20 in the bearing space 381.

[0080] Optionally, the pushing assembly 4 comprises a pushing plate 41 and a pushing driving member 42. The pushing plate 41 is slidingly connected to the loading frame 2 and located on the side of the product 20 away from the support opening assembly 3, and the pushing driving member 42 is connected to the pushing plate 41 to drive the pushing plate 41 to abut against the product 20.

[0081] Specifically, the pushing driving member 42 can be a linear motor module fixed on the top wall of the loading frame 2, and the pushing plate 41 is fixed on the mover, the pushing plate 41 can be inserted into the bearing space 381, the width of the pushing plate 41 is less than the width of the bearing space 381, so that the pushing plate 41 can be smoothly inserted into the bearing space 381, and a pushing strip 43 can be arranged 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 keep a certain gap with the inner side wall of the bearing space 381, so as to ensure that the pushing strip 43 will not be clamped with the material bearing frame 38, and the pushing strip 43 can form sufficient contact area with the product 20, thereby effectively pushing the product 20 to slide in the bearing space 381.

[0082] Optionally, the loading mechanism further comprises a positioning block 6 and a positioning driving member 7. The positioning block 6 is slidingly connected to the bearing frame 1, and one side of the positioning block 6 can extend into the side of the packaging box 10 away from the support opening assembly 3; the positioning driving member 7 is arranged on the bearing frame 1 and connected to the positioning block 6 to drive the positioning block 6 to approach or leave the packaging box 10.

[0083] Specifically, the positioning driving member 7 can adopt a cylinder, the cylinder body of which is fixed on the bearing frame 1, and the positioning block 6 is L-shaped, the lower end of which is fixed on the piston rod of the cylinder, and the upper end of which can be inserted into the packaging box 10, and the upper end of the positioning block 6 can be provided with an insertion inclined surface, so that the cross-sectional area of the end inserted into the packaging box 10 is smaller, so as to be inserted into the packaging box 10 smoothly.

[0084] By arranging the positioning block 6 and the positioning driving member 7, before the packaging box 10 is placed on the loading station, the positioning driving member 7 can drive the positioning block 6 to be away from the loading station, and after the packaging box 10 is placed on the loading station, the positioning driving member 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 station, and the positioning block 6 can also play a stop effect during the process of loading the product 20 into the packaging box 10, so as to reduce the product 20 from the other side of the packaging box 10.
