[0010] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.
[0011] Figure 1 An application scenario of the product defect detection device of this embodiment is shown; Figure 2 FIG. 2 shows another application scenario of the product defect detection device of this embodiment. Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a product defect detection device 100 for a drug packaging line 200. The product defect detection device 100 is applied in the drug packaging line 200, and the drug packaging line 200 is used to produce drugs. Drugs generally include a drug solution, a transparent container for containing the drug solution (such as a vial, an ampoule, a cartridge or a prefilled syringe, etc.), and a transparent packaging for containing the transparent container, wherein the transparent packaging includes a transparent packaging shell and a packaging cover sealed on the transparent packaging shell, and the packaging cover can be transparent or opaque.
[0012] The product defect detection device 100 includes a first visual mechanism 1 and a second visual mechanism 2 provided in a drug packaging line 200, and a control unit 3 connected to the first visual mechanism 1 and the second visual mechanism 2. The first visual mechanism 1 is used to shoot a drug packaging process product 301 from above and obtain a first image. The packaging process product 301 includes a transparent packaging shell, and a transparent container with a drug solution placed in the transparent packaging shell, so the first image includes the imaging of the drug solution, the transparent container and the transparent packaging shell. Once they have some defects, especially appearance defects, they can all be shown in the corresponding imaging. The second visual mechanism 2 is used to shoot a drug packaging finished product 302 from above and obtain a second image. The packaging finished product 302 includes the packaging process product 301 and a packaging cover encapsulated on the transparent packaging shell and cooperating with the transparent packaging shell to accommodate the transparent container and the drug solution. Therefore, the second image includes the imaging of the drug solution, the transparent container, the transparent packaging shell and the packaging cover. Once the drug solution, the transparent container, the transparent packaging shell and the packaging cover have some defects, especially appearance defects, they can all be shown in the corresponding imaging. Therefore, the control unit 3 can identify whether the transparent container, liquid medicine, transparent packaging shell and packaging cover have defects based on the first image and the second image, and the defects include but are not limited to the presence of foreign matter, the presence of labels, position deviation, scratches and bumps, etc.
[0013] It can be seen that the product defect detection device 100 can automatically photograph the transparent packaging, transparent container and liquid medicine from two angles, namely, from the top and bottom, through the first visual mechanism 1 and the second visual mechanism 2, and the control unit 3 automatically identifies whether the transparent packaging, transparent container and liquid medicine have defects based on the photographing results. This multi-angle, automated detection method can not only more comprehensively and accurately identify various defects of drugs, but also improve the quality and efficiency of the detection process, thereby meeting the development needs of the drug packaging line 200.
[0014] According to the present invention, the control unit 3 mentioned above refers to a computing device for performing logical operations, which mainly includes a circuit system composed of a processor (such as a central processing unit CPU or a graphics processing unit GPU), a memory connected to the processor and other necessary electronic components. When in use, the control unit 3 can identify each image based on a pre-trained neural network, and determine whether the drug has defects and the location and type of the defects, etc., wherein the training of the neural network can be obtained based on conventional training methods, which is a technology well known to those skilled in the art and will not be repeated here.
[0015] The layout positions of the key components of the product defect detection device 100 may vary when dealing with different types of drug packaging lines 200. The following two examples are used to describe in detail the layout of the core components of the product defect detection device 100 in the drug packaging line 200.
[0016] As an example, Figure 1As shown, the medicine packaging line 200 at least includes a first conveyor 201, a packaging machine 203 and a second conveyor 202. The first conveyor 201 is used to convey the packaging process product 301 to the second conveyor 202 and pass through the packaging machine 203. The packaging machine 203 is used to connect (such as bonding or welding) the edge of the packaging cover to the edge of the transparent packaging shell of the packaging process product 301 and obtain the packaged product 302. The second conveyor 202 is set to be lower than the first conveyor 201, and is used to receive the packaged product 302 and send it to the downstream process. The first visual mechanism 1 is arranged above the first conveyor 201 and upstream of the packaging machine 203. When the packaging process product 301 of the medicine conveyed by the first conveyor 201 passes through the location of the first visual mechanism 1, the first visual mechanism 1 takes a bird's-eye view of it and obtains a first image. The second visual mechanism 2 is arranged between the first conveyor 201 and the second conveyor 202. When the finished packaged product 302 leaves the first conveyor 201 but does not fall into the second conveyor 202, it will pass through the second visual mechanism 2. The second visual mechanism 2 can shoot the finished packaged product 302 of the medicine from above and obtain a second image. There is no strict requirement for the arrangement position of the control unit 3. Generally, it is only necessary to connect the first visual mechanism 1 and the second visual mechanism 2 through a cable.
[0017] As another example, the pharmaceutical packaging line 200 includes at least a first conveyor 201, a packaging machine 203, a second conveyor 202, a buffer assembly, and a shearing machine 204. The first conveyor 201 is an intermittent conveyor, and is used to convey a chain of packaged products consisting of a plurality of packaged products 301 connected in sequence, so as to convey the chain of packaged products to the second conveyor 202 and pass through the packaging machine 203. The packaging machine 203 is used to connect (such as bonding or welding) the edge of the packaging cover to the edge of the transparent packaging shell of the packaged product 301 and obtain the packaged product 302. The second conveyor 202 is a continuous conveyor, and is used to convey a chain of packaged products consisting of a plurality of packaged products 302 connected in sequence, and pass through the shearing machine 204. The shearing machine 204 is used to cut out each packaged product 302 in the chain of packaged products. The buffer component is arranged between the first conveyor 201 and the second conveyor 202, and is used to buffer the finished packaging chain to balance the interference caused by the different speeds and / or beats of the first conveyor 201 and the second conveyor 202. The buffer component includes a first arc guide frame 2051 arranged at the output end of the first conveyor 201, and a second arc guide frame 2052 arranged at the input end of the second conveyor 202. The first arc guide frame 2051 and the second arc guide frame 2052 are arranged in an inverted eight-shaped shape to form a gap between the two, so that the finished packaging chain is bent due to gravity when passing through the gap, and the change in the size of the bend is regarded as a buffering action. The first visual mechanism 1 is arranged above the first conveyor 201 and upstream of the packaging machine 203. When the first conveyor 201 conveys the chain of packaged products and makes each packaged product 301 pass through the location of the first visual mechanism 1, the first visual mechanism 1 takes a bird's-eye view of one or more packaged products 301 and obtains a first image. The second visual mechanism 2 is arranged below the second arc-shaped guide frame 2052 of the buffer assembly. When each packaged product 302 in the packaged product chain passes through the second arc-shaped guide frame 2052, the second visual mechanism 2 can shoot one or more packaged products 302 from above and obtain a second image. Similarly, there is no strict requirement for the arrangement position of the control unit 3. Generally, it is only necessary to connect the first visual mechanism 1 and the second visual mechanism 2 through a cable.
[0018] The product defect detection device 100 also includes a gripping mechanism (not shown) provided in the drug packaging line 200. The gripping mechanism is connected to the control unit 3, so that the control unit 3 can control the gripping mechanism to take the defective drugs from the second conveyor 202. The gripping mechanism includes a motion unit (such as a mechanical arm or a multi-axis motion platform) electrically connected to the control unit 3 and a clamp provided on the motion unit and driven by the motion unit. Under the control of the control unit 3, the gripping mechanism can use the synergistic effect of the motion unit and the clamp to accurately locate and remove defective drugs, effectively avoiding the impact of defective products on subsequent production links.
[0019] Next, combine Figure 3 , Figure 4 and Figure 5 The first visual mechanism 1 is described in detail. Figure 3 As shown, the first visual mechanism 1 includes a first light-distributing lampshade 11 which is invertedly arranged above the first conveyor 201, a first shooting module 12 which is at least partially arranged in the first light-distributing lampshade 11 and is used to shoot overhead the packaging process product 301 passing under the first light-distributing lampshade 11, and a first light-emitting element 13 which is fixedly arranged in the first light-distributing lampshade 11 and is used to provide lighting for the overhead shooting operation of the first shooting module 12. The first light-emitting element 13 can be an electric lamp such as an LED or a halogen lamp which can generate daylight, and the light emitted by the first light-distributing lampshade 11 is evenly scattered to realize even illumination of the packaging process product 301, so as to ensure that the first shooting module 12 (such as an industrial camera) obtains a clear and high-quality image after shooting, so as to facilitate subsequent detection and identification.
[0020] like Figure 3 and Figure 4 As shown, the product defect detection device 100 may also include a first support frame 41, and a first light-proof box 42 disposed on the first support frame 41 and located above the first conveyor 201. The first light-proof box 42 has a bottom window, the first light-distributing lampshade 11 is fixed in the first light-distributing box 42 and snaps into the bottom window of the first light-distributing box 42, and the first shooting module 12 is installed in the first light-distributing box 42 through the first adapter frame 43, so that the lens of the first shooting module 12 is installed in the first light-distributing lampshade 11 and faces the bottom window of the first light-distributing box 42. Among them, the combination of the first support frame 41 and the first light-proof box 42 not only provides support for the arrangement of the first visual mechanism 1 on the first conveyor 201, but also provides necessary support for the first visual mechanism 1 to implement high-quality shooting to prevent sunlight or factory lights from interfering with the shooting results. In addition, the first light-proof box 42 can also protect the first visual mechanism 1 to achieve the purpose of dustproof, waterproof and anti-collision.
[0021] The first adapter frame 43 mentioned above can be an adjustable frame or a non-adjustable frame, and it is recommended that the adjustable frame is preferred. Figure 3 and Figure 5As shown, the first adapter frame 43 includes a first beam body 431 having a first end plate and a second end plate, a second beam body 432 for hoisting the first shooting module 12, a first adjustment bolt passing through the first end plate of the first beam body 431 and screwed into one side of the first light-proof box 42, a second adjustment bolt passing through the second end plate of the first beam body 431 and screwed into the other side of the first light-proof box 42, and a third adjustment bolt passing through the first beam body 431 and screwed into the top of the second beam body 432. The first end plate of the first beam body 431 has a first waist-shaped hole 4311 for the first adjustment bolt to pass through, the second end plate of the first beam body 431 has a second waist-shaped hole 4312 for the second adjustment bolt to pass through, and the middle part of the first beam body 431 has a third waist-shaped hole 4313 for the third adjustment bolt to pass through. The first waist-shaped hole 4311 has the same extension direction as the second waist-shaped hole 4312, but is perpendicular to the extension direction of the third waist-shaped hole 4313. That is to say, by adjusting the tightness and position of the first adjusting bolt, the second adjusting bolt and the third adjusting bolt, the position of the first shooting module 12 in the first light-proof box 42 and the drug packaging line 200, especially the height position and the left and right position, can be adjusted to obtain a better shooting position.
[0022] Next, combine Figures 6 to 8 The first visual mechanism 1 is described in detail. Figure 6 and Figure 7 As shown, the second visual mechanism 2 includes a second light-averaging lampshade 21 disposed below the second arc-shaped guide frame 2052, a second shooting module 22 at least partially disposed in the second light-averaging lampshade 21 and used to shoot upward the finished packaged product 302 passing through the second arc-shaped guide frame 2052, and a second light-emitting element 23 fixedly disposed in the second light-averaging lampshade 21 and used to provide lighting for the upward shooting operation of the second shooting module 22. The second light-emitting element 23 can be an electric lamp such as an LED or a halogen lamp that can generate daylight, and the light generated by the second light-averaging lampshade 21 is evenly scattered to achieve uniform illumination of the finished packaged product 302, so as to ensure that the second shooting module 22 (such as an industrial camera) obtains a high-quality image after shooting, which is conducive to subsequent detection and recognition. It should be noted that the second shooting module 22 can be set to be tilted or not tilted (such as vertical), in principle, as long as it can ensure that it can completely shoot the finished packaged product 302. However, in order to simplify the algorithm and improve the recognition accuracy, it is recommended to set the lens of the second shooting module 22 to face the packaged finished product 302 that has entered its shooting area.
[0023] like Figure 7As shown, the second visual mechanism 2 also includes a second support frame 51, a second light-proof box 52 arranged on the second support frame 51 and located below the second arc-shaped guide frame 2052, the second light-proof box 52 has a top window, the second light-evening lampshade 21 is fixed in the second light-proof box 52 and snaps into the top window of the second light-proof box 52, and the second shooting module 22 is installed in the second light-proof box 52 through the second adapter frame 53, so that the lens of the second shooting module 22 is installed in the second light-evening lampshade 21 and faces the top window of the second light-proof box 52. Among them, the combination of the second support frame 51 and the second light-proof box 52 not only provides necessary support for the arrangement of the second visual mechanism 2 below the second arc-shaped guide frame 2052, but also provides necessary support for the second visual mechanism 2 to implement high-quality shooting to prevent daylight or factory lights from interfering with the shooting results. In addition, the second light-proof box 52 can also protect the second visual mechanism 2 to achieve the purpose of dustproof, waterproof and anti-collision.
[0024] The structure of the second adapter frame 53 mentioned above can be selected as an adjustable frame or a non-adjustable frame, and it is recommended to be an adjustable frame. As an example, when the second adapter frame 53 is selected as an adjustable frame, it can be directly selected as the same structure as the first adapter frame 43, as described above.
[0025] like Figure 7 As shown, the product defect detection device 100 may also include a fill light 24 disposed above the second arc-shaped guide frame 2052 and providing supplementary lighting when the second shooting module 22 performs upward shooting. The fill light 24 is generally selected as a light source capable of generating parallel light and facing the lens of the second shooting module 22. When the second shooting module 22 performs upward shooting, it can provide additional lighting, better eliminate the shadow area in the image, improve the contrast and clarity of the image, and thus improve the accuracy of defect detection. In addition, the fill light 24 can be disposed above the second arc-shaped guide frame 2052 through an adjustable support rod 25, so that the position of the fill light 24 can be adjusted according to actual needs, and provide the best fill light for the upward shooting of the second shooting module 22. The solution of using the fill light 24 is more suitable for application when the packaging cover is transparent or paper, so that the second shooting module 22 captures the perspective light from the fill light 24 and transmitted through the packaging cover, and presents the defects existing on the outer surface of the packaging cover in the second image.
[0026] More preferably, if Figure 8As shown, the second visual mechanism 2 may also include an elevation angle adjustment mechanism 8 provided between the second support frame 51 and the second light-proof box 52, the elevation angle adjustment mechanism 8 including a plurality of internal threaded holes 81 provided on the second support frame 51 and arranged in a circular array, an adapter plate 82 fixedly provided on the second light-proof box 52 and having a first circular arc through hole 821 and a second circular ring through hole 822, and a first fastening bolt (not shown) passing through the first circular arc through hole 821 of the adapter plate 82 and screwed into one internal threaded hole 81, and a second fastening bolt (not shown) passing through the second circular arc through hole of the adapter plate 82 and screwed into another internal threaded hole 81, wherein the first circular arc through hole 821 and the second circular ring through hole 822 are concentrically arranged, and both expose at least two internal threaded holes 81. When the pitch angle needs to be adjusted, use a suitable tool (such as a wrench) to gently loosen the first fastening bolt and the second fastening bolt, and rotate the second light-proof box 52 equipped with the second visual mechanism 2 to the required angle, for example, facing the packaged finished product 302 passing through the second arc guide frame 2052. In this process, the rotating second light-proof box 52 can carry the adapter plate 82 to rotate, and force the first arc through hole 821 and the second annular through hole 822 to slide on the first fastening bolt and the second fastening bolt in turn, so as to achieve the angle adjustment of the second light-proof box 52. If during the adjustment process, the first arc through hole 821 and the second annular through hole 822 abut against the ends of the first fastening bolt and the second fastening bolt, it is necessary to replace the internal threaded hole 81 where the first fastening bolt and the second fastening bolt are located, and ensure that the second light-proof box 52 equipped with the second visual mechanism 2 can rotate to the required angle, and then tighten the first fastening bolt and the second fastening bolt to complete the adjustment. Among them, the pitch angle adjustment mechanism 8 has the advantages of simple structure and convenient adjustment, and it is easy to ensure that the second visual mechanism 2 is photographed in the most suitable position.
[0027] In addition to providing the above-mentioned product defect detection device 100, the embodiment of the present invention further provides a drug packaging line 200. The drug packaging line 200 includes the product defect detection device 100 mentioned in the above-mentioned embodiment.
[0028] To summarize, according to the above-mentioned product defect detection device 100 and the pharmaceutical packaging line 200 including the same, the product defect detection device 100 can automatically detect defects in transparent packaging, transparent containers and pharmaceutical solutions from multiple perspectives, improve the quality and efficiency of the detection process, and thus meet the development needs of the pharmaceutical packaging line 200.
