Description

Technical Field

[0001] This invention belongs to the field of automated packaging and inspection technology, and in particular relates to a product inspection and packaging line. Background Technology

[0002] In modern industrial production, especially in fields such as cosmetics, pharmaceuticals, and precision electronic components, products must undergo rigorous appearance and packaging quality inspections before leaving the factory. Traditional inspection methods rely heavily on manual visual inspection, which suffers from low efficiency, high labor intensity, inconsistent standards, and is prone to missed or incorrect inspections due to fatigue.

[0003] To achieve automation, existing technologies have developed automated packaging lines equipped with vision inspection systems. These lines typically have vision inspection devices at key workstations, such as inspecting the product itself before boxing or inspecting the inkjet printing on the outer box after sealing.

[0004] However, such production line designs often have inspection points scattered throughout the middle of the production line. Once a defective product is found, it must be rejected online immediately. This mid-process rejection method disrupts the continuity of the production cycle, causing subsequent workstations to be temporarily idle. To maintain the continuity of subsequent processes such as boxing and packing, complex replenishment or buffering mechanisms are often required, increasing the complexity of the equipment and the difficulty of control. Furthermore, the defect detection of the product's protective lining and multi-layer packaging may be incomplete or missing, making it impossible to achieve full-process quality monitoring from the inside out. At the same time, the inspection data at each stage is usually judged independently and processed in real time, lacking global tracking and comprehensive decision-making of product quality information, making it difficult to make a final quality judgment and unified disposal of the finished product that has undergone multiple processes at the final stage.

[0005] Therefore, there is an urgent need to design a product testing and packaging line to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a product testing and packaging line that has the advantages of comprehensive testing, ensuring smooth production, and efficient and accurate management of defective products, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of a product testing and packaging line of the present invention is as follows: A product inspection and packaging line includes a first visual inspection component, a second visual inspection component, a third visual inspection component, a fourth visual inspection component, a fifth visual inspection component, and a sixth visual inspection component. The first visual inspection component is used to detect product defects, the second visual inspection component is used to detect defects in the inner liner, and the third visual inspection component is used to detect defects in the outer packaging. After the product and inner liner are placed into the outer packaging box to form a finished product, the finished product is printed with inkjet code and sealed with plastic. The fourth visual inspection component is used to inspect the plastic seal and inkjet code of the finished product. The fifth visual inspection component is used to detect defects in the packaging. The finished products that pass the inspection are packed into a packaging box. After the packaging box is filled and sealed, the sixth visual inspection component is used to inspect the sealing condition of the packaging box. After the fourth visual inspection component, there is a rejection component. The rejection component is used to reject unqualified products based on all the inspection data of the first, second, third, and fourth visual inspection components. The rejection component includes a data management and tracking system, an identification and triggering mechanism, a physical execution mechanism, and a collection mechanism. The data management and tracking system receives all the inspection data from the first, second, third, and fourth vision inspection components, assigns a unique identifier to each product, and establishes a full-process file. When any inspection data from the first, second, third, and fourth vision inspection components fails to meet the requirements, the defective product is marked. Subsequently, the identification and triggering mechanism locks the defective product and issues an instruction to drive the physical execution mechanism to reject it and move it to the collection mechanism.

[0008] Furthermore, this testing and packaging line also includes a product conveying assembly, an inner liner conveying assembly, and an outer packaging conveying assembly. The product conveying assembly carries and transports the product, and moves the vertically placed product to a horizontally placed product. A first vision inspection assembly is located on the product conveying assembly. The inner liner conveying assembly carries and transports the inner liner plate, and folds the inner liner plate into an inner liner shell. A second vision inspection assembly is located on the inner liner conveying assembly. The outer packaging conveying assembly carries and transports the outer packaging, and folds the outer packaging plate into an outer packaging box. A third vision inspection assembly is located on the outer packaging conveying assembly. The product conveying assembly pushes the horizontally placed product to the inner liner shell assembly. Subsequently, the inner liner conveying assembly pushes the assembled product and inner liner shell into the outer packaging box. Afterward, the outer packaging conveying assembly snaps and seals the outer packaging box to assemble it into a finished product.

[0009] Furthermore, the product conveying assembly includes a product vibratory feeder, a product conveyor line, a product spacing adjustment plate, a slide rail, and a plate chain conveyor line. The product vibratory feeder is used to place the product. The product in the product vibratory feeder is conveyed to the slide rail via the product conveyor line. The slide rail slides the vertically placed product through the inclined plane and naturally flips it into a horizontally placed product. Subsequently, the plate chain conveyor line receives the product from the slide rail. The plate chain conveyor line is equipped with a first pushing mechanism. The first pushing mechanism moves synchronously with the plate chain conveyor line and is responsible for pushing the product to the inner liner assembly. The first vision inspection component includes five first industrial cameras, three of which capture images of the sides of the vertically placed product, one of which captures images of the top surface of the vertically placed product, and one of which captures images of the bottom surface of the horizontally placed product.

[0010] Furthermore, the inner liner conveying assembly includes an inner liner feeding section, an inner liner picking and placing section, an inner liner conveying line, and an inner liner pressing section. The inner liner feeding section is used to separate flat inner liners one by one and supply them to the picking position. The inner liner picking and placing section picks up a single inner liner from the inner liner feeding section, transfers it, and places it on the inner liner conveying line. The inner liner conveying line conveys the inner liner and presses the inner liner into a three-dimensional shape according to the creases through the inner liner pressing section to form an inner liner shell for wrapping and fixing the product. The inner liner conveying line is provided with a second pushing mechanism, which pushes the assembled inner liner shell and the product to move towards the outer packaging conveying line so as to put the assembled product and inner liner shell into the outer packaging box. The second vision inspection component includes two second industrial cameras. One second industrial camera is located below the inner liner loading section, and the other second industrial camera is located on the inner liner picking and unloading section. The two second industrial cameras respectively capture images of the front and back of the inner liner.

[0011] Furthermore, the outer packaging conveying assembly component includes an outer packaging board feeding section, an outer packaging board picking and placing section, an outer packaging conveyor line, and an outer packaging forming section. The outer packaging board feeding section is used to separate flat outer packaging boards one by one and supply them to the picking position. The outer packaging board picking and placing section picks up a single outer packaging board from the outer packaging board feeding section, transfers it, and places it on the outer packaging conveyor line. The outer packaging conveyor line conveys the outer packaging board, and the outer packaging forming section presses the outer packaging board into a three-dimensional shape according to the creases to make it into an outer packaging box. The outer packaging conveyor line is equipped with a fastening mechanism. After the second pushing mechanism pushes the assembled product and inner liner into the outer packaging box, the fastening mechanism folds and fastens the lid of the outer packaging box to form the finished product. The third vision inspection component includes two third industrial cameras. One third industrial camera is located below the outer packaging plate loading section, and the other third industrial camera is located on the outer packaging plate picking and placing section. The two third industrial cameras respectively capture images of the front and back of the outer packaging plate.

[0012] Furthermore, this inspection and packaging line also includes a coding and sealing component, a combination component, and a sealing component. The coding and sealing component prints the production date, QR code, and trademark on the finished product, and then seals it with a plastic film to cover the outer packaging box of the finished product. The fourth vision inspection component is located on the coding and sealing component. The sealed finished product then moves to the combination component. The rejection component is located between the coding and sealing component and the combination component. The rejection component rejects all unqualified products. The combination component assembles the sealed and qualified finished products into a group and then places them into the packaging box until the packaging box is full. The packaging box full of finished products moves to the sealing component. The sealing component folds the lid of the packaging box full of finished products and seals it with tape. The sixth vision inspection component is located on the sealing component.

[0013] Furthermore, the inkjet printing and sealing assembly includes an inkjet printing and marking machine, a sealing machine, and an inkjet printing and sealing conveyor line. The inkjet printing and marking machine prints variable information on the surface of the outer packaging box of the finished product. The sealing machine covers the finished product with a transparent sealing film and performs heat sealing and shrinking to form a transparent outer packaging. The inkjet printing and sealing conveyor line transports the finished product between the inkjet printing and marking machine and the sealing machine, and also transports the finished product after inkjet printing and sealing to the assembly assembly. The fourth vision inspection component includes six fourth industrial cameras, which respectively acquire images of the six surfaces of the finished product after plastic sealing.

[0014] Furthermore, the assembly includes a positioner and a packing robot. The positioner is used to neatly arrange, group, and precisely position the scattered finished products, while the packing robot is used to simultaneously pick up the grouped finished products from the positioner and place them into the waiting boxes in the packaging conveyor assembly assembly.

[0015] Furthermore, the sealing assembly includes a flap folding mechanism, a carton sealing machine, and a sealing conveyor belt. After the packaging box is filled with finished products, the flap folding mechanism first folds the four flaps of the box sequentially or simultaneously, and then the carton sealing machine automatically completes the tape sealing. The sealing conveyor belt is used to transport the packaging box between the flap folding mechanism and the carton sealing machine. The sixth vision inspection component includes a sixth industrial camera, which captures images of the sealing condition of the packaging box.

[0016] Furthermore, this inspection and packaging line also includes a packaging conveying and assembly component, which carries and conveys the packaging, and folds the packaging plate into a packaging box until the packaging box is conveyed to the assembly component. The fifth vision inspection component is located on the packaging conveying and assembly component. The fifth vision inspection component includes two fifth industrial cameras, which respectively capture images of the front and back of the packaging board.

[0017] The present invention has the following advantages: This product inspection and packaging line achieves unmanned operation from individual product loading to pallet palletizing and outbound through a highly integrated, fully automated design. It conducts comprehensive defect screening of products, liners, packaging and even final sealing through multi-level visual inspection at key workstations. It also innovatively adopts a data binding and end-of-line unified rejection strategy, allowing defective semi-finished products to continue to participate in subsequent packaging processes, and rejecting them only once at the final stage based on the full life cycle inspection data. This fundamentally eliminates the problems of production cycle interruption, efficiency reduction and complicated material replenishment caused by mid-process rejection. While ensuring full traceability of product quality, it greatly improves the continuity, stability and overall efficiency of the entire production line. Attached Figure Description

[0020] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of the invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.

[0021] The following is a reference to the appendix. Figure 1 To be continued Figure 10 This invention describes a product testing and packaging line.

[0022] A product inspection and packaging line includes a product conveying assembly 1, an inner liner conveying assembly 3, and an outer packaging conveying assembly 4. The product conveying assembly 1 carries and conveys the product 2, and moves the vertically placed product 2 to a horizontally placed product 2. A first visual inspection assembly 17 is disposed on the product conveying assembly 1. The inner liner conveying assembly 3 carries and conveys the inner liner, and folds the inner liner plate 21 into an inner liner shell 22. A second visual inspection assembly 35 is disposed on the inner liner conveying assembly 3. The outer packaging conveying assembly 4 carries and conveys the outer packaging, and folds the outer packaging plate 23 into an outer packaging box 24. A third visual inspection assembly 46 is disposed on the outer packaging conveying assembly 4. The product conveying assembly 1 pushes the horizontally placed product 2 to the inner liner shell 22 for assembly. Then, the inner liner conveying assembly 3 pushes the assembled product 2 and the inner liner shell 22 into the outer packaging box 24. Afterward, the outer packaging conveying assembly 4 snaps and seals the outer packaging box 24 to assemble it into a finished product 25.

[0023] Product 2 can be a cosmetic product, and in other embodiments of the present invention, it can also be other types of goods.

[0024] Product conveying assembly 1 includes a product vibratory feeder 11, a product conveyor line 13, a product spacing adjustment plate 12, a slide rail 15, and a plate chain conveyor line 14. The product vibratory feeder 11 is used to hold products 2. The products in the product vibratory feeder 11 are conveyed by the product conveyor line 13. The product spacing adjustment plate 12 is located in the middle of the product conveyor line 13. The product spacing adjustment plate 12 is used to adjust the products 2 to the same spacing, and then the products are conveyed again by the product conveyor line 13 until they are conveyed to the slide rail 15. The slide rail 15 slides the vertically placed products 2 through the inclined plane and naturally flips them into flat products. 2. To accommodate the subsequent conveying and bottom visual inspection of the plate chain conveyor line 14, the plate chain conveyor line 14 then receives the product 2 from the slide 15. The plate chain conveyor line 14 is a conveying device composed of chain plates, which can carry and convey single product 2 at a constant spacing and speed. Its speed and rhythm are matched with the whole line to ensure that the product 2 is spaced in an orderly manner, providing stable conditions for visual inspection and subsequent assembly. The plate chain conveyor line 14 is provided with a first pushing mechanism 16, which moves synchronously with the plate chain conveyor line 14 and is responsible for pushing the product 2 to the inner shell 22 for assembly.

[0025] The first vision inspection component 17 is used to detect defects in product 2. The first vision inspection component 17 includes five first industrial cameras 171, of which three first industrial cameras 171 acquire images of the side of the vertically placed product 2, one first industrial camera 171 acquires images of the top surface of the vertically placed product 2, and one first industrial camera 171 acquires images of the bottom surface of the horizontally placed product 2.

[0026] The inner lining conveying assembly component 3 includes an inner lining board feeding section 31, an inner lining board picking and placing section 32, an inner lining conveying line 33, and an inner lining pressing section 34. The inner lining board feeding section 31 is used to separate the flat inner lining boards 21 one by one and supply them to the picking position. The inner lining board picking and placing section 32 picks up a single inner lining board 21 from the inner lining board feeding section 31 and accurately transfers and places it on the inner lining conveying line 33. The inner lining conveying line 33 conveys the inner lining board 21 and presses the inner lining board 21 into a three-dimensional shape according to the creases through the inner lining pressing section 34, so that it becomes an inner lining shell 22 that can wrap and fix the product 2. The inner lining conveying line 33 is provided with a second pushing mechanism 36. The second pushing mechanism 36 moves according to the conveying rhythm of the inner lining conveying line 33 to push the assembled inner lining shell 22 and the product 2 to move towards the outer packaging conveying line 43 so as to put the assembled product 2 and the inner lining shell 22 into the outer packaging box 24.

[0027] The second vision inspection component 35 is used to detect defects in the inner lining plate 21. The second vision inspection component 35 includes two second industrial cameras 351, which respectively acquire images of the front and back of the inner lining plate 21.

[0028] The outer packaging conveying assembly component 4 includes an outer packaging board feeding section 41, an outer packaging board picking and placing section 42, an outer packaging conveying line 43, and an outer packaging forming section 44. The outer packaging board feeding section 41 is used to separate the flat outer packaging boards 23 one by one and supply them to the picking position. The outer packaging board picking and placing section 42 picks up a single outer packaging board 23 from the outer packaging board feeding section 41 and accurately transfers and places it on the outer packaging conveying line 43. The outer packaging conveying line 43 conveys the outer packaging board 23 and, through the outer packaging forming section 44, presses the outer packaging board 23 into a three-dimensional shape according to the creases to make it into an outer packaging box 24. The outer packaging conveying line 43 is provided with a fastening mechanism 45. After the second pushing mechanism 36 pushes the assembled product 2 and inner liner shell 22 into the outer packaging box 24, the fastening mechanism 45 folds and fastens the lid of the outer packaging box 24 to complete the initial sealing and form the finished product 25.

[0029] The third vision inspection component 46 is used to detect defects in the outer packaging plate 23. The third vision inspection component 46 includes two third industrial cameras 461, which respectively acquire images of the front and back of the outer packaging plate 23.

[0030] This inspection and packaging line also includes a coding and sealing component 5, a combination component 7, and a sealing component 8. The coding and sealing component 5 prints the production date, QR code, and trademark on the finished product 25, and then seals it by putting a sealing film on the outer packaging box 24 of the finished product 25. The fourth visual inspection component 51 is set on the coding and sealing component 5. Then the sealed finished product 25 is moved to the combination component 7, which is located on one side of the rejection component 6. The rejection component 6 first rejects the unqualified products, and then the qualified finished products 25 enter the combination component 7. The combination component 7 combines the sealed qualified finished products 25 into a group and then puts them into the packaging box 26 until the packaging box 26 is full. The packaging box 26 filled with finished products 25 is moved to the sealing component 8. The sealing component 8 folds the lid of the packaging box 26 filled with finished products 25 and seals it with tape. The sixth visual inspection component 84 is set on the sealing component 8.

[0031] The inkjet marking and sealing assembly 5 includes an inkjet marking machine, a sealing machine, and an inkjet marking and sealing conveyor line. The inkjet marking machine is typically an inkjet or laser marking device that prints variable information, including production date, batch number, QR code, or specific trademark, on the surface of the outer packaging box 24 of the finished product 25. It is usually driven by a two-axis module to precisely position it at a designated location on each finished product box 25. The sealing machine applies a transparent sealing film to the finished product 25 and performs heat sealing and shrinking. It includes a film holder and film feeding mechanism, and a bag making and sealing / cutting mechanism. The heat shrink tunnel, film rack and film feeding mechanism carry and transport shrink film rolls, bag making and sealing and cutting mechanism make the film into bag shape, wrap the finished product 25, and perform longitudinal sealing and transverse sealing and cutting. Then, the hot air of the heat shrink tunnel makes the wrapped film shrink tightly against the surface of the finished product 25 box to form a smooth, firm and transparent outer packaging. The finished product 25 is transported by the inkjet marking machine and the sealing machine through the inkjet marking and sealing conveyor line, and the finished product 25 after inkjet marking and sealing is transported to the assembly 7 through the inkjet marking and sealing conveyor line.

[0032] After the finished product 25 is printed and sealed, it moves to the assembly 7 via the printing and sealing conveyor line. The fourth vision inspection component 51 performs a comprehensive inspection of the final appearance of the finished product 25. The fourth vision inspection component 51 includes six fourth industrial cameras. The six fourth industrial cameras respectively capture images of the six surfaces of the sealed finished product 25. The conveyor belt that transports the printed and sealed finished product 25 is a transparent belt, so that the bottom of the finished product 25 can be photographed by one of the fourth industrial cameras. The other five fourth industrial cameras respectively photograph the four sides and the top surface of the finished product 25, so as to realize the synchronous or sequential image acquisition of all six surfaces of the sealed finished product 25 to detect the integrity of the sealing film and the quality of printing and marking.

[0033] After finished product 25 is printed and sealed, it moves to assembly 7 via the printing and sealing conveyor line. It first passes through rejection component 6. Rejection component 6 is used to reject defective products based on all the inspection data of the first visual inspection component 17, the second visual inspection component 35, the third visual inspection component 46 and the fourth visual inspection component 51. Rejection component 6 summarizes and tracks all inspection data from product 2 to finished product 25, and removes the accumulated defective products from the main line at the final stage, thereby ensuring the continuity and efficiency of the main production process.

[0034] The rejection component 6 includes a data management and tracking system, an identification and triggering mechanism, a physical execution mechanism, and a collection mechanism. The data management and tracking system receives and binds all inspection results from the first vision inspection component 17, the second vision inspection component 35, the third vision inspection component 46, and the fourth vision inspection component 51. The data management and tracking system assigns a unique identifier to each product 2 entering the production line and records the inspection results of each stage of the entire process in real time. When product 2 completes the final sealing inspection, the system processes it according to its full-process inspection result file. If any stage is judged to be unqualified, the finished product 25 is marked as an object to be rejected. The identification and triggering mechanism is responsible for physically identifying the marked unqualified products and giving precise rejection instructions. Then, it sends an immediate action instruction to the physical execution mechanism, which then directly rejects the unqualified products to the collection mechanism.

[0035] The identification and triggering mechanism includes a position sensor and a control unit. The position sensor uses a high-precision photoelectric sensor or barcode reader to accurately detect the arrival of each finished product 25 and provide a trigger signal. The control unit receives rejection instructions from the data management and tracking system and the trigger signal from the position sensor. When a finished product 25 marked as defective arrives at the rejection station, the PLC calculates the precise delay or position and then sends an immediate action instruction to the physical actuator. The physical actuator then directly rejects the defective product to the collection mechanism.

[0036] Preferably, the physical actuator includes a cylinder and a push rod. When a defective product reaches the predetermined position, the cylinder drives the push rod to extend rapidly, pushing the finished product 25 laterally away from the conveyor line and into the adjacent collection mechanism. In other embodiments of the present invention, other structures such as levers or swing arms can also be used, as long as the defective product can be removed according to the instructions.

[0037] The collection facility is responsible for receiving and temporarily storing rejected non-conforming products. The collection facility includes a slide rail and a collection box. The slide rail guides the pushed-out non-conforming products to slide down a predetermined path for centralized storage of rejected non-conforming products.

[0038] The assembly component 7 is responsible for grouping the final inspected and qualified individual finished products 25 into predetermined quantities and loading them into the packaging boxes 26 in the packaging conveying assembly component 9. The assembly component 7 includes a locator and a packing robot 71. The locator's function is to neatly arrange, group, and precisely position the scattered finished products 25, preparing them for mechanical gripping. The packing robot 71 is a multi-axis Cartesian coordinate robot equipped with a customized vacuum suction cup gripper at its end. It simultaneously picks up the grouped finished products 25 in the locator and then smoothly and accurately transfers and places them into the designated position of the waiting packaging boxes 26 in the packaging conveying assembly component 9. This design ensures neat and efficient packing and avoids misalignment or jamming caused by individual placement.

[0039] Preferably, six finished products 25 are grouped together. In other embodiments of the present invention, a group of finished products 25 may also be other numbers of finished products 25.

[0040] The sealing assembly 8 is used to seal the transport packaging box 26 and to perform a final inspection of its sealing quality. The sealing assembly 8 includes a flap folding mechanism, a box sealing machine, and a sealing conveyor belt. After the packaging box 26 is filled with finished products 25, the flap folding mechanism first folds the four flaps of the box sequentially or simultaneously to prepare for the sealing tape. Then, the box sealing machine automatically completes the tape sealing. The sealing conveyor belt transports the packaging box 26 between the flap folding mechanism and the box sealing machine, and both ends of the sealing conveyor belt are connected to the packaging conveyor line 93 and the outbound conveyor line 81.

[0041] The carton sealing machine includes a tape holder, a tape applicator and smoothing mechanism, and a tape cutting mechanism. The tape holder is used to hold the tape rolls. The tape applicator and smoothing mechanism pulls out the tape, applies it to the center seam of the carton, and smooths and presses it down. After the tape is applied, the tape cutting mechanism automatically cuts the tape.

[0042] The sixth vision inspection component 84 includes a sixth industrial camera, which takes pictures of the top of the sealed box from above or the side to detect sealing quality issues such as whether the tape is completely pasted, whether it is peeling or broken, and whether the box lid is completely closed, and to collect images of the sealing condition of the packaging box 26.

[0043] This testing and packaging line also includes an outbound conveyor line 81 and a palletizing area. The outbound conveyor line 81 transports the tested and qualified full-case products to the palletizing area.

[0044] The palletizing area includes a palletizing robot 82 and a pallet handling station 83. The palletizing robot 82 is responsible for picking up, moving and placing the products. The palletizing robot 82 picks up the full case of products on the outbound conveyor line 81 and places them on the pallet handling station 83.

[0045] This inspection and packaging line also includes a packaging conveying assembly component 9, which carries and conveys the packaging and folds the packaging plate into a packaging box 26 until the packaging box 26 is conveyed to the assembly component 7. The fifth vision inspection component is located on the packaging conveying assembly component 9.

[0046] The packaging conveying assembly 9 includes a packaging board loading section 91, a packaging board picking and placing section, a packaging conveyor line 93, and a packaging forming section. The packaging board loading section 91 is used to separate flat packaging boards one by one and supply them to the picking position. The packaging board picking and placing section picks up a single packaging board from the packaging board loading section 91 and accurately transfers and places it on the packaging conveyor line 93. The packaging conveyor line 93 conveys the packaging board and, through the packaging forming section, opens the bottom flaps of the packaging board and stands up the sides, so that the packaging board initially presents a cuboid shape. The opened carton is placed on a fixed bottom mold, and the small flaps at the bottom of the carton are folded and glued one by one by the packaging forming section to form a stable empty carton with a sealed bottom and an open top. The formed empty carton is released onto the packaging conveyor line 93.

[0047] The packaging conveyor line 93 includes a section of turning roller line 92, which is used to adjust the conveying direction of empty boxes to match the flow direction of the main production line.

[0048] A positioning part is provided at the end of the packaging conveyor line 93. The positioning part positions the empty packaging box 26 on the packaging conveyor line 93. Then, the packing robot 71 of the assembly component 7 loads a set of finished products 25 into the empty packaging box 26 on the packaging conveyor line 93.

[0049] The fifth vision inspection component includes two fifth industrial cameras, which respectively capture images of the front and back of the packaging board.

[0050] For example, if the fifth vision inspection component detects a substandard package, the substandard package will be rejected before it is packed.

[0051] This product testing and packaging line achieves unmanned operation from individual product loading to palletized and shipped products through a highly integrated, fully automated design. It utilizes multi-level visual inspection at key workstations to comprehensively screen for defects in products, liners, packaging, and even final sealing. It innovatively employs a data-binding, end-of-line unified rejection strategy, allowing defective semi-finished products to continue participating in subsequent packaging processes, only to be rejected once at the final stage based on full lifecycle inspection data. This fundamentally eliminates production interruptions, efficiency reductions, and complex material replenishment issues caused by mid-process rejection. While ensuring full traceability of product quality, it significantly improves the continuity, stability, and overall efficiency of the entire production line.
