Description

[0002] In the production and processing of chemical fiber products, chemical fiber spindle appearance defect detection equipment, as a specialized inspection tool used in conjunction with automated production lines, is a crucial device for the rapid identification and sorting of surface defects, damage, and dirt on chemical fiber spindles. Against the backdrop of the chemical fiber industry's development towards automation, intelligence, and high speed, the production efficiency and output of various chemical fiber spindles are continuously improving, placing higher demands on the efficiency and accuracy of spindle appearance quality inspection.

[0003] Currently, traditional chemical fiber spindle appearance inspection mostly relies on manual visual inspection. This is not only inefficient and difficult to adapt to the pace of large-scale, high-speed production, but also fails to meet the rapid inspection needs of batch spindles. Furthermore, during the inspection process, the outer surface of chemical fiber spindles often has attached materials such as loose threads and fly filaments. These attachments not only interfere with the normal identification of defects and damage on the surface of the spindles, leading to frequent missed detections and misjudgments, but also result in poor inspection stability.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1: An embodiment of the present invention provides a device for detecting appearance defects in chemical fiber spindles, such as... Figures 1-9As shown, it includes a conveyor seat 1, on which a conveyor belt 13 is provided for conveying chemical fiber spindles 17. The conveyor seat 1 is provided with a transfer mechanism, a cleaning mechanism and a detection mechanism along the conveying direction of the chemical fiber spindles 17. The detection mechanism includes a drive component 44 and several cameras 45. The drive component 44 is used to drive the chemical fiber spindles 17 to rotate.

[0021] The working principle and beneficial effects of the above technical solution are as follows: the chemical fiber spindle 17 is transported by the transfer mechanism in conjunction with the conveyor belt 13, the cleaning mechanism cleans the thread ends, fly filaments and other debris on the surface of the spindle, and the detection mechanism drives the chemical fiber spindle 17 to rotate through the drive component 44, and completes the all-round appearance defect shooting and detection in conjunction with the camera 45.

[0022] The automated conveying and transfer mechanism effectively solves the problems of low efficiency and difficulty in adapting to high-speed and large-scale production in traditional manual inspection. At the same time, the cleaning mechanism simultaneously removes the threads, shavings and other attachments on the surface of the chemical fiber spindle, avoiding interference with defect identification, reducing missed detections and misjudgments, eliminating the need for additional manual cleaning, reducing labor intensity and shortening the inspection cycle. Combined with the inspection mechanism that can drive the spindle to rotate, it can achieve comprehensive and accurate detection of appearance defects, better meeting the inspection needs of modern chemical fiber production. Example 2: Based on Example 1 above, as follows Figures 1-3 As shown, the conveyor seat 1 includes two symmetrical fixed plates. Several auxiliary rollers 9 are arranged on the side of the two fixed plates that are close to each other, and the auxiliary rollers 9 pass through the conveyor belt 13. A lifting plate 15 is also slidably arranged between the two fixed plates. The lifting plate 15 is located on the right side of the conveyor belt 13. Several chemical fiber spindles 17 are arranged on the lifting plate 15. Electric push rods 19 are arranged on the side of the two fixed plates that are close to each other. The output end of the electric push rods 19 is fixedly connected to the lifting plate 15.

[0023] Preferably, the chemical fiber spindle 17 includes a square plate 23, a vertical rod 21 is rotatably arranged on the square plate 23, a spindle unit 22 is sleeved on the vertical rod 21, a fixing cover 20 is fastened on the vertical rod 21, a toothed ring is arranged on the periphery of the fixing cover 20, and the fixing cover 20 is used to press the spindle unit 22 and the vertical rod 21 together. Several mounting grooves 8 are provided on the conveyor belt 13 along the conveying direction of the chemical fiber spindle 17. There are two rows of mounting grooves 8, and the mounting grooves 8 cooperate with the square plate 23.

[0024] The working principle and beneficial effects of the above technical solution are as follows: Several auxiliary rollers 9 play a supporting and auxiliary transmission role for the conveyor belt 13, preventing the conveyor belt 13 from collapsing or shifting when conveying the chemical fiber spindle 17, and ensuring a smooth and stable conveying process.

[0025] The electric actuator 19 can drive the lifting plate 15 to slide up and down. After the chemical fiber spindle 17 is loaded on the lifting plate 15, the upward movement of the lifting plate 15 facilitates the transfer mechanism to transfer the spindle to the conveyor belt 13. The square plate 23 of the chemical fiber spindle 17 is precisely matched with the mounting groove 8 on the conveyor belt 13, which can limit and fix the chemical fiber spindle 17 to prevent it from sliding or deviating during the conveying process, and further improve the conveying stability. The fixing cover 20 presses and fixes the spindle unit 22 and the vertical rod 21 to prevent the spindle unit 22 from loosening during the detection and conveying process. The toothed ring on its periphery provides a base for the subsequent drive component 44 to drive the spindle to rotate. The overall structure is reasonably designed, which effectively improves the stability and positioning accuracy of the spindle loading and conveying, and provides a reliable guarantee for the smooth progress of subsequent cleaning and detection processes. Example 3: Based on Examples 1-2 above, as follows Figure 1 , Figures 4-6 As shown, a housing 26 is fixedly installed on the front side of the fixed plate. A drive motor 29 is fixedly installed inside the housing 26. A rotating rod 30 is fixedly connected to the output end of the drive motor 29. The rotating rod 30 rotates and extends into the conveyor belt 13. Several drive wheels are also fixedly installed on the rotating rod 30. The drive wheels are used to drive the conveyor belt 13 to rotate.

[0026] Preferably, a pulley 31 is fixedly mounted on the rotating rod 30; the cleaning mechanism includes an electrostatic generating element 24, an electrostatic roller 11 is connected to the front side of the electrostatic generating element 24, a rotating rod is fixedly mounted in the center of the electrostatic roller 11, a stabilizing block 6 is fixedly mounted on the upper end of the fixed plate on the front side, the rotating rod rotates forward and extends into the housing 26, a pulley 18 is mounted on the rotating rod, and a belt 28 is wound around the pulley 31 and the pulley 18; an air blowing box 10 is mounted on the left side of the electrostatic roller 11, and an air suction box 12 is mounted on the right side of the electrostatic roller 11, and both the air blowing box 10 and the air suction box 12 are fixed to the stabilizing block 6 and the outer shell of the electrostatic generating element 24.

[0027] The working principle and beneficial effects of the above technical solution are as follows: The drive motor 29 drives the rotating rod 30 to rotate, which on the one hand drives the conveyor belt 13 to rotate through the drive wheel, realizing the automatic conveying of the chemical fiber spindle 17; on the other hand, the electrostatic roller 11 is driven to rotate synchronously through the pulley 31, belt 28 and pulley 18, which, together with the electrostatic generating element 24, adsorbs the thread ends and fly filaments on the surface of the spindle, and then completes the surface cleaning with the air blowing box 10 and the air suction box 12. Using the same power source to simultaneously perform conveying and cleaning actions results in a simpler structure and more reliable operation. It can complete surface cleaning while conveying the filament spindle, saving additional power and manual operation, and improving overall testing efficiency. Example 4: Based on Example 3 above, as follows Figure 1 , Figures 4-6As shown, a rotating shaft 32 is rotatably mounted in the center of the housing 26. A pulley 3 is fixedly mounted on the rotating shaft 32. A belt 28 cooperates with the pulley 3. A disc 33 is fixedly mounted on the front side of the rotating shaft 32. An extension rod 34 is mounted at an eccentric position on the front side of the disc 33. A square frame 27 is mounted around the extension rod 34. A circular groove is provided on the front side wall of the housing 26. The extension rod 34 slides in the circular groove. A push rod 5 is fixedly mounted on the right end of the square frame 27.

[0028] Preferably, an air box 4 is fixedly installed on the front side of the front fixed plate, a push rod 5 slides into the air box 4, a movable plate 35 is slidably installed inside the air box 4, the push rod 5 is fixedly connected to the movable plate 35, and a movable rod 3 is fixedly installed at the other end of the movable plate 35, the movable rod 3 slides out of the air box 4; an air intake pipe 37 and an air exhaust pipe 38 are provided on the air box 4, both the air intake pipe 37 and the air exhaust pipe 38 are provided with one-way valves, the air intake pipe 37 is connected to the air intake box 12, and the air exhaust pipe 38 is connected to the air blowing box 10.

[0029] Preferably, the suction box 12 has an opening on the side near the electrostatic roller 11, and a scraper 46 is installed obliquely inside the opening. The scraper 46 abuts against the electrostatic roller 11. A toothed rod 25 is symmetrically fixed on the lower surface of the suction box 12, and the toothed rod 25 is meshed with a toothed ring. A plurality of air blowing heads 39 are provided on the lower surface of the air blowing box 10, and the plurality of air blowing heads 39 face the chemical fiber spindle 17.

[0030] The working principle and beneficial effects of the above technical solution are as follows: The belt 28 on the rotating rod 30 drives the pulley 3 and the rotating shaft 32 to rotate synchronously. The rotating shaft 32 drives the disc 33 to rotate. The extended rod 34 on the disc 33 slides in the square frame 27 and moves along the circular groove of the box 26, thereby driving the square frame 27 and the push rod 5 to move back and forth. The push rod 5 drives the moving plate 35 in the air box 4 to slide back and forth. With the help of the one-way valves on the suction pipe 37 and the exhaust pipe 38, the action of sucking air into the suction box 12 and exhausting air into the blowing box 10 is realized. The blowing head 39 of the blowing box 10 blows air towards the chemical fiber spindle 17, blowing off the loose debris on the surface. The debris adsorbed by the electrostatic roller 11 is scraped off by the scraper 46 and sucked away by the suction box 12 in time. At the same time, the toothed rod 25 of the suction box 12 meshes with the toothed ring of the spindle fixing cover 20, driving the spindle to rotate slowly, making the cleaning more comprehensive. The entire cleaning process is powered by the same drive motor, eliminating the need for additional power equipment. This significantly reduces manufacturing costs and energy consumption during use, simplifies the overall structure, reduces the number of parts, lowers the failure rate, and makes maintenance more convenient. The cleaning method is more comprehensive and efficient, integrating air blowing, electrostatic adsorption, scraper removal, and suction. Combined with the rotation of the spindle itself, it can thoroughly clean various deposits on the surface of the spindle. Compared to a single cleaning method, the cleaning effect is greatly improved. No manual operation is required, reducing labor intensity. The scraper 46 not only cleans debris from the electrostatic roller 11 but also protects the electrostatic roller 11, preventing long-term adhesion and wear of the roller surface, thus extending the service life of the electrostatic roller 11. Example 5: Based on Example 4 above, as follows Figure 1 , Figure 5 , Figures 7-8 As shown, a toothed plate 36 is fixedly installed on the upper surface of the other end of the moving rod 3; the transfer mechanism includes two rotating shafts 14, which are rotatably connected to two fixed plates. The rotating shaft 14 on the front side rotates forward and passes through the fixed plate on the front side. A gear 2 is fixedly installed at the front end of the rotating shaft 14, and the gear 2 meshes with the toothed plate 36; a rotating plate 16 is fixedly installed on the rotating shaft 14, and a connecting rod 47 is fixedly installed between the two rotating plates 16. A suction cup assembly is symmetrically slidably installed on the connecting rod 47, and the suction cup assembly is used to pick up the chemical fiber spindle 17.

[0031] The suction cup assembly includes a suction cup rod 41, which is slidably mounted on a connecting rod 47. A suction cup 42 is installed at the lower end of the suction cup rod 41. Guide rails 40 are fixedly mounted on the side of the two fixed plates that are close to each other. An electric telescopic rod 43 is slidably mounted on the guide rail 40. The output end of the electric telescopic rod 43 is slidably connected to the suction cup rod 41. Among them, the electric telescopic rod 43 slides horizontally on the guide rail 40; the suction cup rod 41 slides vertically on the electric telescopic rod 43. The working principle and beneficial effects of the above technical solution are as follows: the moving rod 3 inside the air box 4 moves back and forth, driving the toothed plate 36 at its upper end to move back and forth synchronously. The toothed plate 36 meshes with the gear 2 on the front rotating shaft 14, thereby driving the rotating shaft 14 to rotate in both directions. The rotating shaft 14 drives the rotating plate 16 to rotate synchronously. The rotating plate 16 drives the connecting rod 47 and the suction cup assembly on it to rotate together, realizing the position switching of the suction cup assembly.

[0032] Meanwhile, the electric telescopic rod 43 can slide horizontally on the guide rail 40, driving the suction cup rod 41 to adjust its position horizontally. The electric telescopic rod can also drive the two suction cup rods 41 to move closer or further apart. At the same time, the suction cup rod 41 can also slide vertically on the electric telescopic rod 43, realizing the lifting and lowering of the suction cup 42. Through horizontal and vertical adjustment, the suction cup 42 can be precisely aligned with the chemical fiber spindle 17 on the lifting plate 15. The position of the suction cup 42 can be flexibly adjusted to adapt to chemical fiber spindles 17 of different specifications and placement positions. The suction force of the suction cup 42 firmly adsorbs the spindle, and then the rotation of the turntable 16 smoothly transfers the spindle to the installation groove 8 of the conveyor belt 13, completing the automated transfer and feeding of the spindle. The entire transfer process is coordinated with the conveyor belt's conveying rhythm and the cleaning mechanism's working rhythm to achieve continuous operation. The overall structure design is reasonable and highly practical. Example 6: Based on Examples 1-5 above, as follows Figure 1 and Figure 9 As shown, the testing mechanism also includes a mounting plate 7, which is fixedly connected to the upper surface of two fixed plates. A driving component 44 is symmetrically fixedly arranged on the lower surface of the mounting plate 7, and the driving component 44 is meshed with the gear ring. Several cameras 45 are fixedly arranged on the two fixed plates, and the cameras 45 are used to photograph the chemical fiber spindle 17.

[0033] The working principle and beneficial effects of the above technical solution are as follows: The drive components 44 symmetrically arranged on the lower surface of the mounting plate 7 will continuously mesh with the toothed rings on different chemical fiber spindles 17 during the movement of the conveyor belt 13, thereby driving the chemical fiber spindles 17 to rotate, so that each side of the chemical fiber spindles 17 can be clearly photographed. Several cameras 45 on the two fixed plates work synchronously to photograph the rotating chemical fiber spindles 17 in real time, accurately capturing defects, damage and other problems on its surface, and completing the appearance inspection.

[0034] By integrating the drive unit 44 and the camera 45 through the mounting plate 7, the detection mechanism is integrated, eliminating the need for additional power equipment. The existing drive structure can drive the spindle to rotate, ensuring that the camera 45 can fully cover all surfaces of the spindle and avoid blind spots. At the same time, the camera 45 is fixed on the mounting plate, ensuring a stable shooting angle and capturing defects on the surface of the spindle more clearly and accurately, thus improving detection accuracy. The overall structure is simple and works in conjunction with the original transfer and cleaning mechanisms, further ensuring the comprehensiveness and accuracy of the detection, reducing equipment costs, and improving detection efficiency.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
