[0037] In order to further understand the application content, features and effects of this application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0038] See also Figure 1 and Figure 2 , Figure 1 This is a three-dimensional diagram of the packaging bag defect detection device. Figure 2 This is a structural diagram of the packaging bag defect detection device after hiding the unloading mechanism. The packaging bag defect detection device in this example includes a loading mechanism 1, a conveying mechanism 2, a detection mechanism 3, a rejection mechanism 4, a unloading mechanism 5 and a control system. The loading mechanism 1 is connected to the discharge part of the bag making machine die-cutting device, which is used to load the packaging bag defect detection device. The conveying mechanism 2 transports the packaging bags at the loading mechanism 1 to the rejection mechanism 4 through the detection mechanism 3. The rejection mechanism 4 is used to separate defective packaging bags from qualified packaging bags. The unloading mechanism 5 is used for unloading. The control system is electrically connected to the rejection mechanism 4 and the detection mechanism 3 respectively.

[0039] Among them, the rejection mechanism 4 includes a frame 41, a transmission component 42, a support component 43 and a drive component 44; the drive component 44 is arranged on the frame 41, the transmission component 42 is arranged on the support component 43, and the support component 43 is arranged on the frame 41, one end of which is rotatably connected to the frame 41, and the other end is connected to the drive component 44; the detection mechanism 3 is arranged facing the transmission component 42; the loading mechanism 1, the conveying mechanism 2 and the unloading mechanism 5 are arranged in sequence; the unloading mechanism 5 includes a first unloading component 51 and a second unloading component 52, and the first unloading component 51 and the second unloading component 52 are arranged at intervals along the direction of gravity; the detection mechanism 3 and the drive component 44 are respectively electrically connected to the control system.

[0040] Specifically, the first blanking component 51 is used to carry packaging bags with qualified blanking quality, the second blanking mechanism 5 is used to carry packaging bags with defective blanking quality, the frame 41 is used to carry the supporting component 43 and the driving component 44, the conveying component 42 is arranged on the supporting component 43, the driving component 44 is used to drive the supporting component 43 to swing up and down, and the conveying component 42 is used to convey the packaging bags; the detection mechanism 3 adopts a 25-megapixel industrial area array camera and a matching lens and light source.

[0041] In specific applications, the packaging bags after die-cutting by the bag making machine are in a collection state. After the die-cutting device of the bag making machine discharges the materials, the packaging bags enter the feeding mechanism 1 of the packaging bag defect detection device. The feeding mechanism 1 conveys the packaging bags to the conveying mechanism 2. The area array camera of the detection mechanism 3 shoots the packaging bags on the conveying mechanism 2 to obtain the image of each packaging bag passing through the conveying mechanism 2; the image shot by the detection mechanism 3 is transmitted to the control system through the communication line, and the control system completes the image analysis and processing. The standard value is pre-set in the control system. The set standard value includes the general standard and the special standard. The general standard includes the physical size of the foreign matter, and the special standard includes the defect sample; by comparing the general standard with the data of the packaging bag to be detected By comparison, products that exceed the standard range are found. If the packaging bag to be inspected meets the standard range, an instruction is issued through the control system, and the drive component 44 does not work. After the packaging bag enters the transmission component 42 from the conveying mechanism 2, it enters the first unloading component 51 through the transmission component 42 to complete the unloading of qualified products; if the packaging bag to be inspected does not meet the standard range, an instruction is issued through the control system, and the drive component 44 drives the support component 43 to swing down, and the support component 43 drives the transmission component 42 to move, and the transmission component 42 moves to a position opposite to the second unloading component 52. After the packaging bag enters the transmission component 42 from the conveying mechanism 2, it enters the second unloading component 52 through the transmission component 42 to complete the unloading of unqualified packaging bags.

[0042] In this way, by setting up a detection mechanism 3 facing the conveying mechanism, image recognition is performed on the packaging bag, and the control system judges the image taken by the detection mechanism 3, and uses the upper and lower driving components 44 to drive the support component 43 to swing up and down, so that the conveying component 42 can swing back and forth between the first blanking component 51 and the second blanking component 52. When the packaging bag has no defects, the conveying component 42 is opposite to the first blanking component 51, and when the packaging bag has defects, the conveying component 42 is opposite to the second blanking component, thereby realizing automatic detection and rejection of defective packaging bags.

[0043] Furthermore, one end of the support assembly 43 facing the conveying mechanism 2 is rotatably connected to the frame 41 .

[0044] In this way, compared with the case where the end of the support assembly 43 facing the blanking mechanism 5 is rotatably connected to the frame 41 , the packaging bag can enter the second blanking assembly 52 more easily.

[0045] Please also refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the rejection mechanism. Figure 4 This is a schematic diagram of the mounting plate structure. Furthermore, the support assembly 43 includes a mounting plate 431, a fixing block 432 and a bearing 433. The fixing block 432 is located at one end of the mounting plate 431. It is provided on the side wall of the mounting plate 431 and is fixedly connected to the mounting plate 431. The bearing 433 is fixedly connected to the frame 41. The fixing block 432 is provided with a rotating shaft 4321, and the rotating shaft 4321 is rotatably connected to the bearing 433. The driving assembly 44 is connected to the other end of the mounting plate 431, and the transmission assembly 42 is provided on the mounting plate 431.

[0046] Specifically, the fixed block 432 is located at one end of the mounting plate 431 facing the conveying mechanism, and is located on the side wall of the mounting plate 431. In this example, there are two fixed blocks 432, and the two fixed blocks 432 are respectively located on both sides of the mounting plate 431 and are respectively fixedly connected to the mounting plate 431. The rotating shaft 4321 is provided on the side of the mounting plate 431 facing away from the fixed block 432, and is fixedly connected to the fixed block 432. There are two bearings 433, and the two bearings 433 are respectively provided on both sides of the frame 41. The two rotating shafts 4321 are rotatably connected to the two bearings 433.

[0047] In specific applications, the driving component 44 drives the mounting plate 431 to move up and down. When the driving component 44 drives the mounting plate 431 to swing upward, the conveying component 42 is opposite to the first blanking component 51. When the driving component 44 drives the mounting plate 431 to swing downward, the conveying component 42 is opposite to the first blanking component 51. When the conveying component 42 drives the mounting plate 431 to swing up and down at one end facing away from the conveying mechanism, the mounting plate 431 faces the end of the conveying mechanism and rotates relative to the frame 41.

[0048] Please also refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of the transmission component. Further, the transmission component 42 includes a first driving member 421, a transmission member 422, a transmission roller 423 and a conveyor belt 424. The first driving member 421 is arranged on the mounting plate 431. There are two transmission rollers 423. The two transmission rollers 423 are respectively arranged at both ends of the mounting plate 431. The conveyor belt 424 is sleeved on the two transmission rollers 423. The transmission member 422 is respectively connected to the first driving member 421 and one of the transmission rollers 423 for transmission.

[0049] Specifically, the first driving member 421 is fixed on the mounting plate 431, and the two transmission rollers 423 are arranged at intervals on the mounting plate 431. The transmission rollers 423 are rotatably connected to the mounting plate 431. One of the transmission rollers 423 is connected to the first driving member 421 through the transmission member 422. The conveyor belt 424 is sleeved on the two transmission rollers 423. The conveyor belt 424 is connected to the two transmission rollers 423. The first driving member 421 drives the two transmission rollers 423 to rotate, and the transmission rollers 423 drive the conveyor belt 424 to rotate, thereby transporting the packaging bags.

[0050] Furthermore, the mounting plate 431 is provided with a fixing frame 4311 , and the first driving member 421 is fixedly connected to the fixing frame 4311 .

[0051] In this way, when the end of the mounting plate 431 facing away from the conveying mechanism 2 swings up and down, the conveying assembly 42 can be stably connected to the mounting plate 431 .

[0052] Furthermore, the transmission member 422 includes a first transmission tooth 4221, a second transmission tooth 4222 and a belt 4223. The first transmission tooth 4221 is connected to the first driving member 421, the second transmission tooth 4222 is connected to one of the transmission rollers 423, and the belt 4223 is sleeved on the first transmission tooth 4221 and the second transmission tooth 4222.

[0053] Furthermore, the first driving member 421 includes a driving motor 4211 and a reduction motor 4212. The reduction motor 4212 is arranged at the output end of the driving motor 4211 and is connected to the driving motor 4211. The first transmission tooth 4221 is connected to the reduction motor 4212. The driving motor 4211 is also electrically connected to the control system.

[0054] Please also refer to Figure 6 , Figure 6 This is a schematic diagram of the drive component structure. Further, the drive component 44 includes a first mounting block 441, a second drive member 442 and a second mounting block 443. One end of the second drive member 442 is hinged to the first mounting block 441, and the other end is hinged to the second mounting block 443. The first mounting block 441 is arranged on the frame 41, and the second mounting block 443 is arranged on the mounting plate 431; the second drive member 442 is parallel to the direction of the rotation axis of the first mounting block 441, the direction of the rotation axis of the second drive member 442 and the second mounting block 443, and the direction of the rotation axis of the support component 43 and the frame 41.

[0055] Specifically, the second driving member 442 is driven by a cylinder. In the initial state, the second driving member 442 is arranged along the height direction, and the second mounting block 443 is located below the mounting plate 431. When the second driving member 442 drives the mounting plate 431 to swing up and down, the second driving member 442 rotates relative to the first mounting block 441 and the second mounting block 443 to ensure the stability of the driving component 44 structure.

[0056] In summary, by setting up a detection mechanism facing the conveying mechanism, image recognition of the packaging bag is performed, the control system judges the image taken by the detection mechanism, and the upper and lower driving components are used to drive the supporting component to swing up and down, so that the conveying component can swing back and forth between the first blanking component and the second blanking component. When the packaging bag has no defects, the conveying component is opposite to the first blanking component. When the packaging bag has defects, the conveying component is opposite to the second blanking component, thereby realizing automatic detection and rejection of defective packaging bags.
