The arrangement of the sorting box 5 enables the fresh cut flowers to be effectively classified according to quality or type. The displacement mechanism is installed on the top inner wall of the frame 3, which can accurately control the vertical and horizontal movement of the clamping mechanism to ensure that the clamping operation is accurate. The connecting mechanism plays a bridge role, closely connecting the displacement mechanism with the clamping mechanism, and realizing The two work together. The clamping mechanism is the core component of the equipment. It can accurately clamp the fresh cut flowers on the conveyor belt and move them. The existence of the direction adjustment mechanism enables the clamping mechanism to flexibly adjust its direction to adapt to the clamping needs of different fresh cut flowers. The visual sorting control mechanism, as the "brain" of the entire equipment, is responsible for the comprehensive control of the sorting equipment. It uses machine vision technology to perform real-time image analysis of fresh cut flowers, accurately classify fresh cut flowers according to preset sorting standards, and control the displacement mechanism, clamping mechanism and other components to perform corresponding operations.

[0024] The displacement mechanism includes a rodless cylinder 6 and a telescopic cylinder 7. The rodless cylinder 6 is fixedly mounted on the top inner wall of the frame 3, and the telescopic cylinder 7 is fixedly mounted on the output block of the rodless cylinder 6. The rodless cylinder 6 is fixedly mounted on the top inner wall of the frame 3, providing a stable foundation for the entire displacement mechanism, and the telescopic cylinder 7 is fixedly mounted on the output block of the rodless cylinder 6, so that the telescopic cylinder 7 can move in a straight line direction under the drive of the rodless cylinder 6. The rodless cylinder 6 is characterized by a compact structure and smooth movement. Since there is no rod, the friction and wear caused by the movement of the rod of the traditional cylinder are avoided, thereby improving the service life. When the rodless cylinder 6 is driven, the telescopic cylinder 7 can realize continuous and stable displacement in the horizontal direction, and the telescopic cylinder 7 is responsible for controlling the movement of the clamping mechanism in the vertical direction. Through the telescopic action of the telescopic cylinder 7, the height of the clamping mechanism can be accurately adjusted, so as to realize the clamping of fresh cut flowers in different positions. The design of this displacement mechanism enables the clamping mechanism to realize accurate and stable movement in both horizontal and vertical directions, which provides strong technical support for the sorting of fresh cut flowers. At the same time, due to the combination of the rodless cylinder and the telescopic cylinder, the entire displacement mechanism has a compact structure and simple operation, which improves the overall performance and reliability of the sorting equipment.

[0025] The connecting mechanism includes a connecting plate 8 and a connecting shaft 9. The connecting plate 8 is fixedly mounted on the output rod of the telescopic cylinder 7, and the connecting shaft 9 is rotatably mounted on the bottom of the connecting plate 8. The connecting plate 8 is fixedly mounted on the output rod of the telescopic cylinder 7, which means that the telescopic action of the telescopic cylinder 7 can directly drive the connecting plate 8 to move accordingly. This design ensures a stable connection between the displacement mechanism and the connecting mechanism, so that the entire sorting equipment can maintain a high degree of coordination and stability during operation. The connecting shaft 9 is rotatably mounted at the bottom of the connecting plate 8, which enables the connecting shaft 9 to rotate within a certain range. This design allows the clamping mechanism to be fine-tuned when necessary to adapt to the clamping requirements of different fresh cut flowers. At the same time, the rotatable installation of the connecting shaft 9 also increases the flexibility of the entire connecting mechanism, so that the clamping mechanism can remain stable and smooth during movement.

[0026] The clamping mechanism includes a shell 10, two rotating shafts 11, and two clamping claws 12. The shell 10 is fixedly mounted on the bottom end of the connecting shaft 9. The two rotating shafts 11 are rotatably mounted on the inner wall of the shell 10. The two clamping claws 12 are respectively fixedly sleeved on the two rotating shafts 11. The two rotating shafts 11 are rotatably mounted on the inner wall of the shell 10. This rotating installation method enables the rotating shaft 11 to rotate within a certain range, thereby driving the clamping claws 12 to perform corresponding clamping actions. This design not only ensures that the clamping claws 12 can be flexibly opened and closed to adapt to fresh cut flowers of different sizes, but also ensures the accuracy and reliability of the clamping action. The two clamping claws 12 are respectively fixedly sleeved on the two rotating shafts 11, which means that the opening and closing action of the clamping claws 12 is directly controlled by the rotation of the rotating shaft 11. The design of the clamping claws 12 usually has sufficient elasticity and clamping force to ensure that the fresh cut flowers can be firmly clamped and kept stable during movement.

[0027] A servo motor 13 is fixed on the inner wall of the housing 10, and a worm 14 is fixedly installed on the output shaft of the servo motor 13. The worm 14 is rotatably connected to the inner wall of the housing 10. A worm wheel 15 is fixedly sleeved on the two rotating shafts 11. The two worm wheels 15 are meshed with the worm 14. The servo motor 13 can directly drive the worm 14 to rotate accurately. At the same time, in order to ensure the stable operation of the worm 14, we still keep it rotatably connected to the inner wall of the housing 10. Similar to the previous embodiment, a worm wheel 15 is fixedly sleeved on the two rotating shafts 11, and this Both worm wheels 15 mesh with the worm 14. This meshing design ensures that the rotation of the worm 14 can be accurately transmitted to the worm wheel 15, thereby driving the opening and closing of the rotating shaft 11 and the clamping claw 12. The introduction of the servo motor 13 brings many advantages. First, the servo motor has the characteristics of high precision and high response speed, and can achieve precise control of the opening and closing of the clamping claw 12, greatly improving the accuracy and efficiency of sorting. Secondly, the servo motor also has the characteristics of good stability and high reliability, and can maintain stable performance during long-term operation, ensuring the continuous and efficient operation of the sorting equipment.

[0028] The direction adjustment mechanism includes a stepper motor 16, a driving gear 17 and a driven gear 18. The stepper motor 16 is fixedly mounted on the bottom of the connecting plate 8. The driving gear 17 is fixedly sleeved on the output shaft of the stepper motor 16. The driven gear 18 is fixedly sleeved on the connecting shaft 9. The driving gear 17 is meshed with the driven gear 18. The output shaft of the stepper motor 16 is fixedly sleeved with the driving gear 17, which means that the rotation of the stepper motor 16 can directly drive the driving gear 17 to rotate. The driven gear 18 is fixedly sleeved on the connecting shaft 9. The connecting shaft 9 is a key component of the connecting mechanism and the clamping mechanism. Therefore, the rotation of the driven gear 18 will directly affect the direction of the clamping mechanism. In order to realize the driving gear 17 driving the driven gear 18, we make the driving gear 17 meshed with the driven gear 18. In this way, when the stepper motor 16 drives the driving gear 17 to rotate, the driven gear 18 will also rotate accordingly, thereby realizing the adjustment of the direction of the clamping mechanism.

[0029] The visual sorting control mechanism includes a plurality of visual cameras 19 and a visual sorting control host 20. The plurality of visual cameras 19 are arranged on the top inner wall of the frame 3. The visual sorting control host 20 is arranged on the top of the frame 3. The visual sorting control host 20 is electrically connected to the conveyor belt 2, the rodless cylinder 6, the telescopic cylinder 7, the servo motor 13, the stepper motor 16 and the visual cameras 19. The plurality of visual cameras 19 are arranged on the top inner wall of the frame 3, so as to ensure that they can capture the fresh cut flower images on the conveyor belt 2 in all directions. These visual cameras 19 are arranged on the top inner wall of the frame 3. The visual camera 19 has the characteristics of high resolution and fast response, and can capture the shape, color, size and other characteristic information of the fresh cut flowers in real time. The visual sorting control host 20 is arranged on the top of the frame 3. It is the core of the entire visual sorting control mechanism. The visual sorting control host 20 is electrically connected with the conveyor belt 2, the rodless cylinder 6, the telescopic cylinder 7, the servo motor 13, the stepper motor 16 and the visual camera 19, which means that it can receive and process the information from these components in real time, and accurately control the fresh cut flowers according to the preset sorting standards. When working, the visual The camera 19 will capture the image of the fresh cut flowers in real time and transmit the image information to the visual sorting control host 20. The visual sorting control host 20 will quickly process and analyze the images, identify the characteristic information of the fresh cut flowers, and judge whether they meet the requirements according to the preset sorting standards. If they meet the requirements, the visual sorting control host 20 will send instructions to the conveyor belt 2, the rodless cylinder 6, the telescopic cylinder 7, the servo motor 13 and the stepper motor 16 to control them to work together to accurately deliver the fresh cut flowers to the specified location. If they do not meet the requirements, the visual sorting control host 20 will control The conveyor belt 2 continues to convey the fresh cut flowers to the next sorting link or for other processing. This design makes the entire fresh cut flower sorting process automated and intelligent, greatly improving the efficiency and accuracy of sorting. At the same time, due to the use of visual cameras and visual sorting control host, the sorting process is more objective and reliable, reducing the interference and errors of human factors. In summary, the utility model realizes accurate sorting and control of fresh cut flowers by introducing a visual sorting control mechanism. This design not only improves the performance of the equipment, but also provides strong support for the automation and intelligence of the fresh cut flower production line.

[0030] The working principle of the fresh cut flower sorting equipment based on machine vision provided by the utility model is as follows:

[0031] The fresh cut flowers are transported by the conveyor belt 2, and the fresh cut flowers are visually photographed and identified by multiple visual cameras 19. The visual sorting control host 20 controls and starts multiple rodless cylinders 6 according to the visual shooting identification data. The multiple rodless cylinders 6 drive the multiple clamping claws 12 to move horizontally, so as to move the multiple clamping claws 12 to the top of different kinds of fresh cut flowers. The multiple telescopic cylinders 7 drive the multiple clamping claws 12 to move downward. The multiple servo motors 13 drive the multiple worms 14 to rotate. The rotation of the multiple worms 14 drives the multiple worm gears 15 to rotate. The rotation of the multiple worm gears 15 drives the multiple rotating shafts 11 and the multiple clamping claws 12 to rotate in opposite directions, so as to clamp the fresh cut flowers. Then, the clamped fresh cut flowers are raised by the telescopic cylinders 7, and the clamped fresh cut flowers are moved to the top of the multiple sorting boxes 5 by the multiple rodless cylinders 6. The ends of the multiple clamping claws 12 are moved away from each other by controlling the servo motors 13 to rotate in the opposite direction, so as to put the different kinds of fresh cut flowers into the multiple sorting boxes 5, so as to complete the visual sorting of the fresh cut flowers.
