Technical Field

[0001] This utility model relates to the field of logistics sorting and error correction technology, and in particular to a vision-based online intelligent detection and error correction system for order packages in logistics sorting lines. Background Technology

[0002] Commercial order sorting is the foundation for the cigarette turnover and handover between the tobacco industry and the social retail industry. Currently, commercial sorting is mainly automated and manual, which has a certain probability of causing discrepancies between the sorting results of the cigarette pack sorting line and the order, resulting in incorrect order packages of cigarettes that are "too few, too many, or wrong". Once such a situation is discovered, workers must stop the machine to find the problem, which consumes a lot of manpower and resources, and it is difficult to improve sorting efficiency.

[0003] Existing vision-based online intelligent detection and error correction systems for order packages on logistics sorting lines have the problem that when a problematic order is detected, workers must stop the machine to search for it, which consumes a lot of manpower and resources and makes it difficult to improve sorting efficiency. Therefore, a vision-based online intelligent detection and error correction system for order packages on logistics sorting lines is needed. Utility Model Content

[0004] The purpose of this invention is to provide a vision-based online intelligent detection and error correction system for order packages in logistics sorting lines. This system solves the problem in the existing technology that when a problematic order is found, workers must stop the machine to search for it, which consumes a lot of manpower and resources and makes it difficult to improve sorting efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vision-based online intelligent detection and error correction system for order packages in a logistics sorting line, comprising a base frame, a guide rail fixed to the outer side of the base frame, several insertion holes in the middle of the guide rail, a supplementary lighting mechanism slidably mounted on the outer side of the guide rail, a mounting frame fixed to the top of the rear end of the base frame, a first high-definition industrial camera symmetrically mounted in the middle of the mounting frame, a conveying mechanism mounted at the front end of the base frame, a resistance heating plate mounted at the bottom of the conveying mechanism, a cigarette pack placed on the top of the conveying mechanism, a customized light source box fixed to the exterior of the front end of the conveying mechanism, a positioning frame welded to the front end of the conveying mechanism, and a second high-definition industrial camera mounted on the top of the positioning frame.

[0006] Preferably, the supplementary lighting mechanism includes a sliding frame slidably connected to the guide rail, an insert rod is provided on the outer side of the bottom end of the sliding frame, a rotating ring is rotatably installed on the top of the sliding frame, a screw passes through the middle of the rotating ring, the rotating ring and the screw are threadedly connected, a lifting frame is welded to the top of the screw, a first motor is fixed on the outer side of the top end of the lifting frame, and a supplementary lighting tube is connected to the output end of the first motor.

[0007] Preferably, the sliding frame forms an engaging structure between the insert rod and the insert hole, and the lifting frame forms a lifting structure between the rotating ring, the screw and the sliding frame.

[0008] Preferably, the conveying mechanism includes a fixed frame welded to the front end of the base frame, a second motor is installed at the top of the fixed frame, the output end of the second motor is connected to a first rotating roller, a heating conveyor belt is provided on the outer side of the first rotating roller, and a second rotating roller is connected to the inner side of one end of the heating conveyor belt.

[0009] Preferably, the second rotating roller forms a transmission structure with the first rotating roller through the heating conveyor belt. Multiple second rotating rollers are arranged at equal intervals along the inner horizontal direction of the heating conveyor belt, and the bottom of the heating conveyor belt is arranged parallel to the top of the resistance heating plate.

[0010] Preferably, the cigarette pack is arranged in a translational structure between the heated conveyor belt and the customized light source box, and the cigarette pack is covered with a PE film.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up a sliding mechanism, two high-definition industrial cameras and a specially customized supplementary lighting mechanism are deployed at the cigarette pack sorting and forming chamber to collect images of the cigarettes inside the order cigarette packs. The AI ​​deep learning image recognition algorithm is used to identify the specifications and quantity of the cigarettes and compare them with the orders in the current database. The supplementary lighting tube is driven by a first motor to rotate and adjust the supplementary lighting angle, and the height is adjusted by rotating the adjustment ring and driving the screw through the thread to raise and lower. The appropriate height of the supplementary lighting tube can be stably and flexibly adjusted to effectively prevent reflection and facilitate cleaning and shooting operations. The front and rear positions of the supplementary lighting tube can be flexibly adjusted by sliding along the guide rail. The overall adjustment operation is more flexible, ensuring the supplementary lighting effect and facilitating image acquisition and comparison operations.

[0013] 2. By setting up a conveyor mechanism, the top cigarette pack is conveyed by controlling the heated conveyor belt. The bottom resistance heating plate heats the heated conveyor belt, ensuring that the PE film on the contact surface with the heated conveyor belt is simultaneously heated and sealed at high temperature during the conveying process. The operation is flexible and convenient. When the order package passes through the PE film heated conveyor belt, the PE film may become scalded, causing the cigarette pack inside the order package to fall out and slip. When the order package leaves the PE film heated conveyor belt, it enters a customized light source box, where a second high-definition industrial camera is used to capture images and recheck whether the specifications and quantity of cigarettes in the order package are abnormal. If any abnormality occurs in the order package at the above two points, it will be alerted through alarms, human-machine interface prompts, and control equipment start / stop.

A guide rail 2 is fixed to the outside of the base frame 1. Several insertion holes 3 are opened in the middle of the guide rail 2. A supplementary lighting mechanism 4 is slidably installed on the outside of the guide rail 2. A mounting frame 5 is fixed to the top of the tail end of the base frame 1. A first high-definition industrial camera 6 is symmetrically installed in the middle of the mounting frame 5. A conveying mechanism 7 is installed at the front end of the base frame 1. A resistance heating plate 8 is installed at the bottom of the conveying mechanism 7. A cigarette pack 9 is placed on the top of the conveying mechanism 7. A customized light source box 10 is fixed to the outside of the front end of the conveying mechanism 7. A positioning frame 11 is welded to the front end of the conveying mechanism 7. A second high-definition industrial camera 12 is installed on the top of the positioning frame 11.

[0020] The supplementary lighting mechanism 4 includes a sliding frame 401 that is slidably connected to the guide rail 2. A rod 402 is provided on the outer side of the bottom end of the sliding frame 401. A rotating ring 403 is rotatably mounted on the top of the sliding frame 401. A screw 404 passes through the middle of the rotating ring 403. The rotating ring 403 and the screw 404 are threaded together. A lifting frame 405 is welded to the top of the screw 404. A first motor 406 is fixed on the outer side of the top end of the lifting frame 405. The output end of the first motor 406 is connected to a supplementary lighting tube 407.

[0021] The sliding frame 401 forms a locking structure between the insert rod 402 and the insertion hole 3, and the lifting frame 405 forms a lifting structure between the sliding frame 401 and the rotating ring 403 and the screw 404. The overall adjustment operation is more flexible, ensuring the supplementary lighting effect, reducing reflection, and facilitating image acquisition and comparison operations.

[0022] The conveying mechanism 7 includes a fixed frame 701 welded and fixed to the front end of the base frame 1. A second motor 702 is installed at the top of the fixed frame 701. The output end of the second motor 702 is connected to a first rotating roller 703. A heating conveyor belt 704 is provided on the outer side of the first rotating roller 703. A second rotating roller 705 is connected to the inner side of one end of the heating conveyor belt 704.

[0023] The second roller 705 forms a transmission structure with the first roller 703 through the heating conveyor belt 704. Multiple second rollers 705 are arranged at equal intervals along the inner horizontal direction of the heating conveyor belt 704. The bottom of the heating conveyor belt 704 is arranged parallel to the top of the resistance heating plate 8. In use, the heating conveyor belt 704 is controlled to convey the top tobacco strip wrapping 9, and the resistance heating plate 8 at the bottom heats the heating conveyor belt 704.

[0024] The cigarette pack 9 is connected to the customized light source box 10 via a heated conveyor belt 704 to form a translation structure. The cigarette pack 9 is covered with PE film. The bottom resistance heating plate 8 heats the heated conveyor belt 704, ensuring that the PE film on the contact surface with the heated conveyor belt 704 is heated and sealed at high temperature during the conveying of the top cigarette pack 9. The operation is flexible and convenient.

[0025] Working principle: First, two high-definition industrial cameras 6 and a specially customized supplementary lighting mechanism 4 are deployed at the cigarette pack sorting and forming warehouse to collect images of the cigarette packs in the order cigarette pack 9. The AI ​​deep learning image recognition algorithm is used to identify the specifications and quantity of the cigarettes and compare them with the orders in the current database. When the order pack passes through the PE film heating conveyor belt 704, the PE film may be ironed, causing the cigarettes in the order pack to fall out and slip. When the order pack leaves the PE film heating conveyor belt 704, it enters the customized light source box 10, and a second high-definition industrial camera 12 is used to collect images to recheck whether the specifications and quantity of the cigarettes in the order pack are abnormal. If the order pack is abnormal at the above two points, it will be alerted by means of alarm, human-machine interface prompts, and control equipment start and stop.

[0026] The supplementary lighting tube 407 is driven by the first motor 406 to adjust its angle, and its height is adjusted by rotating the adjusting ring 403 to drive the screw 404 to raise and lower via the thread. This allows for stable and flexible adjustment of the appropriate height of the supplementary lighting tube 407, effectively preventing glare and facilitating cleaning and shooting operations. The front and rear positions of the supplementary lighting tube 407 can be flexibly adjusted by sliding along the guide rail 2, making the overall adjustment operation more flexible, ensuring the supplementary lighting effect, and facilitating image acquisition and comparison operations. During use, the heating conveyor belt 704 is controlled to transport the top cigarette pack 9, and the bottom resistance heating plate 8 heats the heating conveyor belt 704, ensuring that the PE film on the contact surface with the heating conveyor belt 704 is simultaneously heated and sealed at high temperature during the transport of the top cigarette pack 9. The operation is flexible and convenient.

[0027] High-definition industrial cameras are used to capture images of the appearance, labels, and other features of the cigarette packs in the formed order cigarette packs (9). Then, AI deep learning image recognition algorithms are used to identify the specifications and quantity of the cigarettes and compare them with the orders in the current database to identify possible sorting errors during the sorting process. The project requires the identification of cigarette packs that have been wrapped in PE film, and a customized spherical integrating light source cover and customized light source box (10) are needed to make the cigarette packs inside the PE film non-reflective and clear.
