[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] Please see Figure 1-5This utility model provides a technical solution: an online detection device for low-smoke halogen-free flame-retardant strips, including a base 1, a support frame 5 fixedly connected to the top of the base 1, a first support plate 2 symmetrically fixedly connected to the top of the base 1 and outside the support frame 5, a second conveying roller 4 rotatably connected inside the first support plate 2, and a first conveying roller 3 rotatably connected inside the first support plate 2 and directly above the second conveying roller 4. The flame-retardant strip is located between the first conveying roller 3 and the second conveying roller 4, making the movement of the flame-retardant strip smoother. Industrial cameras 6 are symmetrically installed inside the support frame 5. The two sets of industrial cameras 6 respectively capture real-time images of the front and back of the flame-retardant strip. The captured images are transmitted to a computer and processed by the image processing system in the computer. The image processing system analyzes the images using image recognition technology to detect whether there are defects, scratches, or other problems on the surface of the low-smoke halogen-free flame-retardant strip. A connecting frame 7 is rotatably connected inside the support frame 5. First brushes 11 are symmetrically arranged on both sides of the connecting frame 7. When the connecting frame 7 rotates, it carries the first brushes 11 to the mirrors of the industrial cameras 6. The head is cleaned. Symmetrically arranged second brushes 12 are positioned on the side of the connecting frame 7 away from the first brush 11. The connecting frame 7, along with the second brushes 12 on both sides, contacts the flame-retardant strip to clean its surface. Both the first brush 11 and the second brush 12 are made of carbon fiber. Carbon fiber brushes have good flexibility and elasticity, allowing them to gently contact the lens surface. Furthermore, carbon fiber is not prone to static electricity, preventing dust adsorption and reducing the possibility of secondary contamination. Rotating rods 21 are rotatably connected between the two sides of the connecting frame 7 and the support frame 5. The rotating rod 21 rotates, causing the connecting frame 7 to rotate as well. There are two sets of rotating rods 21. One end of the rotating rod 21 passes through one side of the support frame 5 and is fixedly connected to the first gear 20. The rotation of the first gear 20 causes the rotating rod 21 to rotate. A sector plate 16 is rotatably connected to one side of the support frame 5. An arc rack 17 is slidably connected to one side of the sector plate 16. The arc rack 17 moves along one side of the sector plate 16. One side of the arc rack 17 meshes with the first gear 20. The movement of the arc rack 17 causes the first gear 20 to rotate.

[0024] Furthermore, a limiting block 22 is symmetrically fixedly connected to one side of the fan-shaped plate 16 and the outer side of the arc-shaped rack 17. When one side of a set of limiting blocks 22 moves to one side of the arc-shaped rack 17, the limiting block 22 moves the arc-shaped rack 17. During the process of the limiting block 22 moving to one side of the arc-shaped rack 17, the arc-shaped rack 17 remains stationary.

[0025] Furthermore, a connecting rod 15 is rotatably connected to one side of the sector plate 16, and an eccentric wheel 13 is rotatably connected to the end of the connecting rod 15 away from the sector plate 16. The rotation of the eccentric wheel 13 causes the sector plate 16 to rotate back and forth through the connecting rod 15.

[0026] Furthermore, a second motor 14 is fixedly connected to one side of the support frame 5 via a fixing frame. The output end of the second motor 14 passes through one side of the fixing frame and is fixedly connected to the center of one end of the eccentric wheel 13. After the second motor 14 is turned on, it drives the eccentric wheel 13 to rotate.

[0027] Furthermore, a second support plate 8 is fixedly connected to one end of the base 1. The second support plate 8 is provided in two sets, and a winding rod 10 is rotatably connected between the two sets of second support plates 8. The winding rod 10 winds up the tested flame-retardant strip.

[0028] Furthermore, a first motor 9 is fixedly connected to one side of the second support plate 8, and one end of the winding rod 10 passes through one side of the second support plate 8 and is fixedly connected to the output end of the first motor 9. After the first motor 9 is turned on, it rotates the winding rod 10.

[0029] Furthermore, a filter box 23 is fixedly connected to one side of the top of the base 1. A fan 24 is fixedly connected to one end of the filter box 23. One end of the fan 24 extends through one side of the filter box 23 into the interior of the filter box 23. A filter plate is fixedly connected inside the filter box 23 to filter the gas entering the filter box 23 and prevent dust and impurities from entering the fan 24 and causing damage to the fan 24. A connecting pipe 25 is fixedly connected to the top of the filter box 23. A dust suction port 26 is fixedly connected to the outside of the connecting pipe 25. The dust and impurities swept off enter the connecting pipe 25 through the dust suction port 26 and then enter the filter box 23.

[0030] In use, one end of the flame-retardant tape to be tested is passed between the first conveyor roller 3 and the second conveyor roller 4 and wound onto the surface of the take-up rod 10. The first motor 9 is turned on, and the first motor 9 drives the take-up rod 10 to rotate, which in turn winds the flame-retardant tape, causing the tape to move between the first conveyor roller 3 and the second conveyor roller 4. Two sets of industrial cameras 6 are turned on, and as the flame-retardant tape moves, the industrial cameras 6 take real-time pictures of both sides of the low-smoke halogen-free flame-retardant tape. The captured images are transmitted to the image processing system, which analyzes the images using image recognition technology to detect whether there are defects, scratches, or other problems on the surface of the low-smoke halogen-free flame-retardant tape. The second brushes 12 on both sides of the connecting frame 7 are in contact with the front and back of the flame-retardant tape. As the flame-retardant tape moves, the second brushes 12 clean its surface. The second motor is turned on. 14. The second motor 14 drives the eccentric wheel 13 to rotate. The eccentric wheel 13 drives the sector plate 16 to rotate back and forth through the connecting rod 15. When the limiting block 22 at one end of the sector plate 16 contacts the arc rack 17, the arc rack 17 rotates with the sector plate 16. The rotation of the arc rack 17 drives the first gear 20 to rotate. The first gear 20 drives the connecting frame 7 to rotate through the rotating rod 21. When the connecting frame 7 rotates, the first brushes 11 on both sides come into contact with the lens of the industrial camera 6 to clean the lens of the industrial camera 6 and prevent dust from accumulating on the lens surface, which would make the captured image blurry and unable to identify the defects on the surface of the flame retardant strip. At the same time, the fan 24 is turned on. Under the action of the fan 24, the dust and impurities swept off enter the connecting pipe 25 through the dust suction port 26 and then enter the filter box 23.
