Description
Technical Field
[0001] This utility model belongs to the field of image recognition technology, specifically relating to a rapid detection device for color printing quality based on image recognition. Background Technology
[0002] In the production process of color printed products, product quality inspection is a crucial step in ensuring that the products leaving the factory are qualified. Traditional color printing quality inspection mainly relies on manual visual inspection. This method is not only inefficient, but also prone to missed inspections and misjudgments due to visual fatigue. With the development of machine vision technology, automatic inspection devices based on image recognition are gradually being applied to the field of color printing quality inspection.
[0003] During the inspection process, the color-printed products are fixed only by the friction of the conveyor belt. When the conveyor belt runs or the camera moves, the products are prone to displacement, resulting in blurred images or positional deviations, which affects the inspection accuracy. This is especially true for color-printed products with smooth surfaces, which are more likely to slip during the inspection process. To address this issue, we have designed a rapid color-printed quality inspection device based on image recognition to provide an alternative technical solution. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figure 1-6 A rapid color printing quality detection device based on image recognition includes an identification sorting box 1, a first conveyor belt 2 at one end of the identification sorting box 1, a second conveyor belt 3 at the other end of the identification sorting box 1, a defective product collection box 4 on one side of the identification sorting box 1, a top detection head 9 at the top inside the identification sorting box 1, a conveying mechanism for image conveying inside the identification sorting box 1, a fixing mechanism for fixing the color printing image on the outside of the identification sorting box 1, and a rotating mechanism for rotating the identification sorting box 1 at the bottom.
[0024] The rotating mechanism includes a vertical column 8, a T-shaped rotating block 10 is rotatably connected inside the vertical column 8, a second drive motor 11 is fixed inside the vertical column 8 by bolts, the output end of the second drive motor 11 is fixedly connected to the T-shaped rotating block 10, and the top of the T-shaped rotating block 10 is fixedly connected to the identification and sorting box 1.
[0025] The vertical column 8 has a T-shaped rotating groove inside. The T-shaped rotating block 10 is located inside the T-shaped rotating groove and is rotatably connected to the vertical column 8 through the T-shaped rotating groove. The T-shaped rotating groove allows the T-shaped rotating block 10 to rotate inside the vertical column 8. The rotation of the T-shaped rotating block 10 enables the identification and sorting box 1 to rotate.
[0026] Here, the operation of the second drive motor 11 enables the T-shaped rotating block 10 to rotate inside the vertical column 8. The rotation of the T-shaped rotating block 10 enables the identification and sorting box 1 to rotate, thereby enabling the identified color printed image to be transported to the designated position.
[0027] The conveying mechanism includes an active rotating roller 12, which is located at the bottom of the identification and sorting box 1 and is rotatably connected to the identification and sorting box 1. Driven rotating rollers 13 are provided at both ends of the top of the active rotating roller 12 and inside the identification and sorting box 1. A sorting conveyor belt 6 is sleeved on the outside of the two driven rotating rollers 13 and the active rotating roller 12. The sorting conveyor belt 6 is bolted to one side of the identification and sorting box 1. The output end of the sorting conveyor belt 6 is fixedly connected to the active rotating roller 12.
[0028] Here, the operation of the first drive motor 5 enables the active rotating roller 12 to rotate. The rotation of the active rotating roller 12, through the setting of the sorting conveyor belt 6, enables the driven rotating roller 13 to rotate, thereby enabling the color-printed images on the top of the two sorting conveyor belts 6 to be transported and sorted.
[0029] The fixing mechanism includes a U-shaped support frame 15, which is close to the outside of the identification and sorting box 1 and fixedly connected to the identification and sorting box 1. A third drive motor 16 is fixed at one end of the identification and sorting box 1. A first longitudinal threaded rod 17 is fixed at the output end of the third drive motor 16. A second longitudinal threaded rod 18 is fixed at the end of the first longitudinal threaded rod 17 away from the third drive motor 16. A longitudinal sliding plate 19 is threadedly connected to the outside of both the first longitudinal threaded rod 17 and the second longitudinal threaded rod 18. An oblique rotating column 20 is rotatably connected to the bottom of the longitudinal sliding plate 19. A transverse connecting plate 21 is rotatably connected to the bottom of the oblique rotating column 20. A vertical lifting plate 14 is fixed to the top of one side of the transverse connecting plate 21. Positioning suction cups 7 are provided at both ends of the vertical lifting plate 14. The positioning suction cups 7 can fix the color printed image by the operation of the air pump.
[0030] A partition plate is rotatably connected to the connection between the first longitudinal threaded rod 17 and the second longitudinal threaded rod 18 via a bearing. The top of the partition plate is fixedly connected to the U-shaped support frame 15, so that the first longitudinal threaded rod 17 and the second longitudinal threaded rod 18 can rotate synchronously, thereby preventing bending between the first longitudinal threaded rod 17 and the second longitudinal threaded rod 18.
[0031] The U-shaped support frame 15 has a dovetail slider fixed inside, and the longitudinal sliding plate 19 has a dovetail groove inside. The U-shaped support frame 15 and the longitudinal sliding plate 19 are slidably connected by the cooperation of the dovetail slider and the dovetail groove. By setting the dovetail slider and the dovetail groove, the longitudinal sliding plate 19 can move laterally inside the U-shaped support frame 15, thereby guiding the movement trajectory of the longitudinal sliding plate 19 inside the U-shaped support frame 15.
[0032] The identification and sorting box 1 has a vertical slide groove inside. The horizontal connecting plate 21 is located inside the vertical slide groove and is slidably connected to the identification and sorting box 1 through the vertical slide groove. The setting of the vertical slide groove allows the horizontal connecting plate 21 to slide vertically inside the identification and sorting box 1, thereby allowing the vertical lifting plate 14 to be height-adjusted inside the identification and sorting box 1.
[0033] Here, the operation of the third drive motor 16 enables the first longitudinal threaded rod 17 and the second longitudinal threaded rod 18 to rotate. The rotation of the first longitudinal threaded rod 17 and the second longitudinal threaded rod 18 enables the longitudinal sliding plate 19 to move inside the U-shaped support frame 15. The movement of the longitudinal sliding plate 19, through the oblique rotating column 20, enables the transverse connecting plate 21 to slide vertically inside the identification and sorting box 1. The vertical sliding of the transverse connecting plate 21 enables the position and height of the vertical lifting plate 14 to be adjusted. When the two positioning suction cups 7 come into contact with the color-printed image, the operation of the air pump enables the positioning suction cups 7 to fix the color-printed image so that the top detection head 9 can fix the color-printed image. When the two positioning suction cups 7 can be vertically lifted and lowered, the restriction on the sorting conveyor belt 6 is released so that the color-printed image can move on the surface of the sorting conveyor belt 6.
[0034] By setting up a fixing mechanism, the position and height of the positioning suction cup 7 can be adjusted, which can stably adsorb the bottom of the color-printed product during detection, effectively preventing the product from shifting and sliding on the surface of the sorting conveyor belt 6, ensuring that the product position is completely fixed during image acquisition, and greatly improving the accuracy and consistency of image recognition and detection. The setting of the conveying mechanism and the rotating mechanism makes it more convenient to sort the color-printed products after recognition.
[0035] Working principle: The operation of the third drive motor 16 enables the first longitudinal threaded rod 17 and the second longitudinal threaded rod 18 to rotate. The rotation of the first longitudinal threaded rod 17 and the second longitudinal threaded rod 18 enables the longitudinal sliding plate 19 to move inside the U-shaped support frame 15. The movement of the longitudinal sliding plate 19, through the oblique rotating column 20, enables the transverse connecting plate 21 to slide vertically inside the identification and sorting box 1. The vertical sliding of the transverse connecting plate 21 enables the position and height of the vertical lifting plate 14 to be adjusted. When the two positioning suction cups 7 come into contact with the color printed image, the operation of the air pump enables the positioning suction cups 7 to fix the color printed image so that the top detection head 9 can fix the color printed image. When the two positioning suction cups 7 can be vertically lifted and lowered, the restriction on the sorting conveyor belt 6 is released so that the color printed image can move on the surface of the sorting conveyor belt 6.
[0036] The operation of the first drive motor 5 enables the active rotating roller 12 to rotate. The rotation of the active rotating roller 12, through the setting of the sorting conveyor belt 6, enables the driven rotating roller 13 to rotate, thereby enabling the color-printed images on the top of the two sorting conveyor belts 6 to be transported and sorted.
[0037] The operation of the second drive motor 11 enables the T-shaped rotating block 10 to rotate inside the vertical column 8. The rotation of the T-shaped rotating block 10 enables the identification and sorting box 1 to rotate, thereby transporting the identified color-printed image to the designated location.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
