[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] In the embodiment, Figure 1-4 A carton automatic visual inspection line is provided, comprising a processing table 1, on the surface of which a first conveyor line 2 and a second conveyor line 3 for transporting cartons are arranged, and the second conveyor line 3 is located at the unloading end of the first conveyor line 2, the first conveyor line 2 is provided with a centering component 4 for adjusting the loading posture of the cartons, the first conveyor line 2 is also provided with a partition component 5 for loading the stacked cartons one by one, the second conveyor line 3 is provided with a visual inspection camera 6, the cartons are placed at the loading end of the first conveyor line 2, and the first conveyor line 2 drives the cartons to move forward, and at the same time The centering component 4 is adjusted according to the model of the carton to ensure that the carton maintains the correct posture when loading, so that the subsequent visual inspection can be carried out accurately. Then the partition component 5 separates the stacked cartons one by one to ensure that each carton can enter the next stage of the inspection process individually and orderly. The visual inspection camera 6 adopts advanced visual inspection technology to conduct a comprehensive inspection of the surface of the carton. By capturing the image of the carton and performing a series of complex image processing and analysis, the visual inspection camera 6 can identify stains, damage, creases and other defects on the surface of the carton, and record the inspection results in real time.

[0021] Reference Figure 1-4, wherein the centering assembly 4 includes a slide bar 41, the slide bar 41 is fixedly mounted on the first conveyor line 2, and the number of the slide bars 41 is two, and two sliders 42 are slidably connected to the slide bar 41, and one side surface of the two sliders 42 is provided with a limit plate 43;

[0022] Through the above-mentioned structural setting, the slider 42 is provided with an open slot, and the open slot is threadedly connected with a hand screw. The open slot can be closed by tightening the hand screw, thereby fixing the slider 42 on the slide bar 41. By adjusting the positions of the two sliders 42, the limit plates 43 on both sides can clamp and position the carton from both sides, thereby realizing the centering adjustment of the carton. In this way, the posture and position of the carton are accurately fixed, providing good conditions for subsequent visual inspection.

[0023] Reference Figure 1-4 , wherein the partition assembly 5 includes a mounting seat 51, the mounting seat 51 is fixedly mounted on the first conveying line 2 and is located between the two slide bars 41, the mounting seat 51 is provided with a slide groove 52, a moving block 53 is slidably connected in the slide groove 52, a telescopic rod 54 is fixedly mounted on the moving block 53, a paper pressing wheel 55 is provided at the telescopic end of the telescopic rod 54, and the paper pressing wheel 55 is provided with a spring 56 located on the outside of the telescopic rod 54 between the moving blocks 53;

[0024] Through the above-mentioned structural setting, the slide groove 52 on the mounting seat 51 provides a sliding track for the moving block 53, so that the moving block 53 can reciprocate in the slide groove 52, and a loading channel for cartons to pass through is arranged between the moving block 53 and the first conveyor line 2. This loading channel only allows a single carton to pass through. Therefore, when the stacked cartons are transported forward, the cartons on the upper layer are blocked by the baffle, while the cartons on the bottom layer continue to be loaded under the drive of the first conveyor belt 2. The setting of the spring 56 ensures that the paper pressing wheel 55 has a certain buffering effect when pressure is applied to avoid damage to the cartons.

[0025] Reference Figure 1-4 , wherein a paper pressing plate 13 is provided on a side surface of the moving block 53 close to the second conveying line 3, and the paper pressing plate 13 is provided in an "L" shape, and a baffle is fixedly installed on a side surface of the moving block 53 away from the second conveying line 3;

[0026] Through the above-mentioned structural arrangement, the "L"-shaped design of the paper pressing board 13 enables it to play an effective supporting and guiding role when the carton passes through, and at the same time it can limit the movement range of the carton to a certain extent, so that it remains on a predetermined path.

[0027] Reference Figure 1-4, wherein the second conveyor line 3 is rotatably connected to a rotating shaft 7 through a bearing seat, a connecting arm 8 is fixedly installed on the rotating shaft 7, and a pressure roller 9 is rotatably connected to one end of the connecting arm 8 away from the rotating shaft 7;

[0028] Through the above-mentioned structural arrangement, the pressing roller device composed of the rotating shaft 7, the connecting arm 8 and the pressing roller 9 on the second conveyor line 3, the carton will move along the direction of the conveyor line, and the pressing roller 9 will contact the top of the carton to apply a certain pressure to the carton, ensuring that the carton remains stable during the conveying process and preventing it from shifting or tilting due to vibration or bumps, thereby realizing stable conveying and precise control of the carton.

[0029] Reference Figure 1-4 , wherein a distance detection sensor 10 is fixedly installed between the first conveyor line 2 and the second conveyor line 3;

[0030] Through the above-mentioned structural setting, the distance detection sensor 10 plays a monitoring and protection role in the automatic visual inspection line of cartons.

[0031] Reference Figure 1-4 , wherein a collecting box 11 is provided at the unloading end of the second conveying line 3, and an air nozzle 12 is provided above the collecting box 11;

[0032] Through the above-mentioned structural setting, the main function of the collection box 11 is to collect and temporarily store the cartons that have been inspected for subsequent classification, packaging or other processing. The air nozzle 12 is installed above the collection box 11. Its function is to assist the falling and positioning of the cartons by blowing air, thereby improving the efficiency and accuracy of the entire unloading process.
