Abstract
Description
Technical Field
[0001] This utility model relates to the field of sorting machines, and more specifically, to a visual recognition-based packaging bag sorting machine. Background Technology
[0002] After the lettering on the outer packaging bags of chemical products is printed, packaging inspection is required. During chemical packaging processing, sorting is necessary to remove products with poor printing quality before further processing. Traditionally, sorting is done manually. In pursuit of speed, manual sorting inevitably leads to missed inspections. Visual inspection of printing is labor-intensive, time-consuming, and inaccurate. Applying machine vision inspection technology to sorting machines is a trend in modern production. Visual inspection sorting machines can be used to inspect the printed lettering on packaging bags. Visual inspection equipment refers to machine vision inspection systems that utilize CCD image sensors. The equipment's CCD industrial camera takes high-speed, real-time photos of the object being inspected and transmits them to the image processing and control system to determine whether the printing quality of the packaging is up to standard.
[0003] Based on this, a search on the patent website revealed Chinese patent application number 202021342762.7, which discloses a visual sorting device, including a workbench, a first conveyor belt, a second conveyor belt, and a robotic arm. The first conveyor belt, the second conveyor belt, and the robotic arm are arranged on the top surface of the workbench, with the robotic arm positioned between the first and second conveyor belts. A graphic recognition device is arranged above the first conveyor belt. When a product is qualified, the graphic recognition device sends a signal to the robotic arm, which then picks up the qualified product and places it into a packaging box on the second conveyor belt. Unqualified products are continuously conveyed backward by the first conveyor belt.
[0004] It can be seen that the above-mentioned patent application has the following shortcomings: When using a traditional visual sorting device, the graphic recognition component needs to acquire a product image when detecting and recognizing the packaging bag. However, the device lacks a limiting mechanism for the packaging bag during detection. When the device is subjected to external force, the position of the packaging bag is easily displaced, which will affect the printing detection quality of the packaging bag by the graphic recognition component and reduce the practicality of the device. Utility Model Content
[0005] The purpose of this invention is to provide a visual recognition-based packaging bag sorting machine. By using this device, the problem in the above-mentioned traditional visual sorting devices is solved. When the graphic recognition component detects and identifies packaging bags, it needs to acquire product images. However, the device lacks a limiting mechanism for the packaging bags during detection. When the device is subjected to external force, the position of the packaging bags is easily displaced, which affects the printing detection quality of the packaging bags by the graphic recognition component and reduces the practicality of the device.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a visual recognition packaging bag sorting machine, including a base, a first conveyor belt and a second conveyor belt are provided on the top of the base, and a collection box is provided on one side of both the first conveyor belt and the second conveyor belt; a limiting component is provided on the top of the base, and two sets of the limiting component are provided, with a visual monitoring mechanism provided at the upper end of the two sets of the limiting component; a driving component is provided on the top surface of the base, and the driving component is located on one side of the second conveyor belt; the driving component includes a driving box fixedly connected to the top of the base, and a first motor is fixedly connected inside the driving box; the limiting component includes a mounting box fixedly connected to the top surface of the base, an opening is provided on one side of the mounting box, a clamping block is slidably connected to one side of the mounting box, and a driving motor is fixedly connected to the outside of the mounting box.
[0007] Preferably, the drive assembly further includes a first gear rotatably connected inside the drive box, and the first gear is fixedly connected to the output end of the first motor.
[0008] Preferably, a rack block is meshed with one side of the first gear, and the rack block is slidably connected to one side of the drive box.
[0009] Preferably, one side of the rack block extends to the outside of the drive box, and a push block is fixedly connected to one side of the rack block, the push block being disposed on one side of the second conveyor belt.
[0010] Preferably, the visual monitoring mechanism includes a bracket fixedly connected between the two sets of mounting boxes, and an image recognition mechanism is provided on one side of the bracket, which is positioned directly above the second conveyor belt.
[0011] Preferably, the limiting component further includes a first threaded rod rotatably connected inside the mounting box, the first threaded rod being fixedly connected to the output end of the drive motor, a limiting rod being fixedly connected inside the mounting box, and a connecting plate being slidably connected inside the mounting box.
[0012] Preferably, the connecting plate is threaded to the outer periphery of the first threaded rod, the connecting plate is slidably connected to the outer periphery of the limiting rod, and the clamping block is fixedly connected to the connecting plate at the corresponding position; a controller is provided on one side of the base, and the controller is electrically connected to the first motor, the image recognition mechanism and the drive motor respectively.
[0013] Compared with the prior art, the technical solution provided by this utility model has the following advantages:
[0014] 1. The support frame is equipped with an image recognition mechanism that can take high-speed, real-time photos of the packaging bag under test. The controller then performs comprehensive analysis to determine whether the printing of the packaging bag is qualified. When it is necessary to check the printing quality of the packaging bag, the packaging bag is placed on the second conveyor belt, and the second conveyor belt transport mode is activated. The second conveyor belt transports the packaging bag to be tested directly below the image recognition mechanism. To prevent the packaging bag from shifting during the inspection process, the user simultaneously activates two sets of drive motors. The drive motors drive the first threaded rod to rotate, which in turn drives the connecting plate to move closer to the packaging bag along the limit rod. The connecting plate then pushes the clamping blocks to move closer to the packaging bag. The two sets of clamping blocks clamp and limit the packaging bag on both sides. After being limited, the packaging bag will be more stable when the visual monitoring mechanism performs quality inspection. This setting limits the packaging bag during the inspection process through the positioning mechanism, which can prevent the packaging bag from shifting during the printing inspection process. It allows for better use of the visual monitoring mechanism to perform printing inspection of the items during the stable process, thereby improving the detection accuracy of the device.
[0015] 2. After the device uses an image recognition mechanism to detect the packaging bag, it starts two sets of drive motors. These motors drive two sets of first threaded rods to rotate in opposite directions. The first threaded rods drive the connecting plate to move towards the inside of the mounting box, causing the clamping blocks to move away from the packaging bag. This continues until both clamping blocks retract into the mounting boxes. The clamping blocks then cease their function of limiting the packaging bag and continue to move the bag forward using the second conveyor belt. When the controller detects a defective packaging bag, it sends a signal to the first motor, activating its operating mode. The first motor drives the first gear to rotate forward, which in turn drives the rack block to move outward from the drive box. The rack block then drives the pusher block to push closer to the packaging bag, using the pusher block to remove the defective bag from the second conveyor belt. Qualified items are pushed to the top of the first conveyor belt, then the first motor drives the first gear to move in the opposite direction. The rack block retracts into the drive box, and the pusher block moves towards the drive box until it returns to its original position. At the same time, the first conveyor belt starts its transmission mode, using it to transfer unqualified printed packaging bags and collect them through the collection box at the front of the first conveyor belt. Qualified printed packaging bags continue to be smoothly transported via the second conveyor belt and collected through the collection box at the front of the second conveyor belt. This operation facilitates the subsequent unified processing of unqualified printed packaging bags by workers, and helps the device to separate qualified and unqualified printed packaging bags for collection. The operation is simple and quick, avoiding manual separation and improving the efficiency of the device. Attached Figure Description

[0025] The present invention will be further described below with reference to the embodiments.
[0026] Example 1:
[0027] Please see Figures 1-5 The visual monitoring mechanism 3 includes a bracket 31 fixedly connected between two sets of mounting boxes 21. An image recognition mechanism 32 is provided on one side of the bracket 31 and is located directly above the second conveyor belt 13. The limiting component 2 also includes a first threaded rod 25 rotatably connected inside the mounting box 21. The first threaded rod 25 is fixedly connected to the output end of the drive motor 24. A limiting rod 26 is fixedly connected inside the mounting box 21. A connecting plate 27 is slidably connected inside the mounting box 21. The connecting plate 27 is threadedly connected to the outer periphery of the first threaded rod 25 and slidably connected to the outer periphery of the limiting rod 26. The clamping block 23 is fixedly connected to the corresponding position of the connecting plate 27.
[0028] Example 2:
[0029] Please see Figures 1-4 The drive assembly 4 also includes a first gear 44 rotatably connected inside the drive box 41. The first gear 44 is fixedly connected to the output end of the first motor 45. A rack block 43 is meshed with one side of the first gear 44. The rack block 43 is slidably connected to one side of the drive box 41. One side of the rack block 43 extends to the outside of the drive box 41. A push block 42 is fixedly connected to one side of the rack block 43. The push block 42 is located on one side of the second conveyor belt 13. A controller 5 is located on one side of the base 1. The controller 5 is electrically connected to the first motor 45, the image recognition mechanism 32, and the drive motor 24, respectively.
[0030] In summary, the working principle is as follows: The visual monitoring mechanism 3 of this practical device uses the NASD-SX0 model visual monitoring component from Nastan, which is a mature existing technology on the market and will not be elaborated further here. An image recognition mechanism 32 is installed on the bracket 31. The image recognition mechanism 32 can take high-speed, real-time photos of the printed text on the packaging bag being tested. The data is then comprehensively analyzed by the controller 5, which determines whether the packaging bag is qualified. When it is necessary to check whether the printing on the packaging bag is qualified, the packaging bag is placed on the second conveyor belt 13, and the second conveyor belt 13 is activated. The second conveyor belt 13 transports the packaging bag to be tested directly below the image recognition mechanism 32. To prevent the packaging bag from being damaged during the inspection process... If a deviation occurs, the user simultaneously activates both sets of drive motors 24. The drive motors 24 drive the first threaded rod 25 to rotate, which in turn drives the connecting plate 27 to move closer to the packaging bag along the limiting rod 26. The connecting plate 27 then pushes the clamping block 23 to move closer to the packaging bag. The two sets of clamping blocks 23 clamp and limit the packaging bag on both sides. After being limited, the packaging bag will be more stable when the visual monitoring mechanism 3 checks the printing quality. This setup limits the packaging bag during the detection process through a positioning mechanism, preventing deviation during printing and inspection. It also allows for better use of the visual monitoring mechanism 3 to inspect the items, thereby improving the device's detection accuracy.
[0031] After the device uses the image recognition mechanism 32 to detect the printing of the packaging bag, it starts two sets of drive motors 24. The two sets of drive motors 24 drive the two sets of first threaded rods 25 to rotate in opposite directions. The first threaded rods 25 drive the connecting plate 27 to move into the mounting box 21, and then the clamping block 23 moves away from the packaging bag until both sets of clamping blocks 23 retract into the two sets of mounting boxes 21. The clamping blocks 23 stop limiting the packaging bag and continue to use the transmission mode of the second conveyor belt 13 to move the packaging bag forward. When the controller 5 analyzes that the printed packaging bag is unqualified, the controller 5 sends a signal to the first motor 45 and makes the first motor 45 start working mode. The first motor 45 drives the first gear 44 to rotate forward. The first gear 44 drives the rack block 43 to move outward from the drive box 41. The rack block 43 drives the push block 42 to push towards the packaging bag. 2. The defective items on the second conveyor belt 13 are pushed to the top surface of the first conveyor belt 12. Then, the first motor 45 drives the first gear 44 to move in the opposite direction. The rack block 43 will retract into the drive box 41, and the push block 42 will move towards the drive box 41 until the push block 42 returns to its original position. At the same time, the transmission mode of the first conveyor belt 12 is turned on, and the defective packaging bags are transferred by the first conveyor belt 12 and collected by the collection box 11 on the front side of the first conveyor belt 12. The qualified packaging bags will continue to be transported smoothly by the second conveyor belt 13 and collected by the collection box 11 on the front side of the second conveyor belt 13. This operation will facilitate the subsequent unified processing of defective printed packaging bags by workers. It can assist the device in separating and collecting qualified and unqualified printed packaging bags. The operation is simple and quick, avoids manual separation, and improves the working efficiency of the device.
