[0021] The technical solution of the present invention will now be clearly and completely described in conjunction with preferred embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Example 1 like Figures 1-6 A visual method warping roller detection device includes a detection platform 1 and a horizontal screw drive platform installed on the top of the detection platform 1. Two warping roller supports 2 are arranged on the top of the detection platform 1 in a relative position. Each of the two warping roller supports 2 is fitted with a clamping component 3. One of the clamping components 3 is drivenly connected to a power mechanism 5. The power mechanism 5 can synchronously rotate and adjust the two warping rollers 13 that are clamped and limited between the two clamping components 3. Each of the two warping roller supports 2 is equipped with a first conductive slip ring 4. The first conductive slip ring 4 can supply power to the clamping component 3 without interfering with the rotation of the clamping component 3. The clamping assembly 3 includes a composite support cylinder 31. One end of the composite support cylinder 31 is mounted on the inner side of the top of the corresponding warping roller bracket 2 via a bearing. The other end of the composite support cylinder 31 has a semi-open groove that communicates with its own space, providing sufficient clearance for the subsequent assembly of the warping roller 13 and the clamping assembly 3, improving the flexibility and convenience of assembling the warping roller 13 before and after inspection, and improving inspection efficiency. Furthermore, the front and rear end side walls of the other end of the composite support cylinder 31 are both fitted with a first electric push rod 33, and the front and rear end surfaces of the other end of the composite support cylinder 31 are both equipped with clamping plates 32. The output end of the clamping plate 32 is connected to the middle of the first electric push rod 33 for transmission, thereby meeting the use requirements for automatic clamping and output of the warping roller 13 and further improving the efficiency of inspection operations. The power mechanism 5 includes a reducer 51, a first brake servo motor 52, and a T-shaped linkage shaft 53. The input end of the reducer 51 is connected to the output end of the first brake servo motor 52. A support seat is installed between the housing surface of the first brake servo motor 52 and the surface of the corresponding warping roller bracket 2. The output end of the reducer 51 is connected to one end of the T-shaped linkage shaft 53. The other end of the T-shaped linkage shaft 53 passes through the clearance space in the middle of the corresponding first conductive slip ring 4 and is fixedly connected to the inner wall in the middle of the corresponding composite support cylinder 31. After the power mechanism 5 is combined with the two warping roller brackets 2 and the two clamping components 3 for transmission, the subsequent warping rollers 13 can rotate at a set uniform speed. The output structure of the horizontal lead screw transmission platform is connected to the longitudinal lead screw transmission mechanism 10, and the output structure of the longitudinal lead screw transmission mechanism 10 is connected to the first CCD camera 11. Under the alternating transmission of the horizontal lead screw transmission platform and the longitudinal lead screw transmission mechanism 10, the first CCD camera 11 can perform horizontal displacement or vertical displacement to take a full picture of the warping roller 13 held by the two clamping components 3. The horizontal lead screw transmission platform includes a first positioning seat 6, a first lead screw 7, a second brake servo motor 8, and a first nut seat 9. The bottom of the first positioning seat 6 is fixed to the top of the detection platform 1. The first lead screw 7 is mounted on the inner side of the middle part of the first positioning seat 6 through a bearing. The second brake servo motor 8 is mounted on one side surface of the first positioning seat 6 and is connected to one end of the first lead screw 7. The first nut seat 9 serves as the output structure of the horizontal lead screw transmission platform and is threaded to the surface of the middle part of the first lead screw 7. The bottom of the first nut seat 9 is engaged with a first slide rail fixed on the inner wall of the bottom of the first positioning seat 6. Thus, through the precise drive positioning of the horizontal lead screw transmission platform, the first CCD camera 11 can be controlled to move automatically left and right to complete a detailed scanning of the overall contour of the warping roller. The longitudinal lead screw transmission mechanism 10 includes a semi-open housing 101. The bottom of the semi-open housing 101 is fixed to the top of the first nut seat 9. A second lead screw 102 and a second nut seat 103 are housed inside the semi-open housing 101. The second lead screw 102 is mounted on the inner side of the middle of the semi-open housing 101 via bearings. The second nut seat 103 serves as the output structure of the longitudinal lead screw transmission mechanism 10 and is threadedly connected to the surface of the second lead screw 102. The housing surface of the first CCD camera 11 is mounted on the structural surface of the second nut seat 103 facing the open space of the semi-open housing 101. A CCD camera 11 can be connected to an image recognition device, and the supporting software inside the image recognition device can store a database of warping roll contour data of various specifications, as well as software functions to receive and compare the scanned imaging data transmitted by the first CCD camera 11. The second nut seat 103 of the first CCD camera 11 is internally engaged with a second slide rail fixed on the inner wall of the semi-open housing 101. Through the set longitudinal screw transmission mechanism 10, the positioning effect is precisely driven, and the first CCD camera 11 can be controlled to move up and down automatically so as to complete a detailed scanning of the overall contour of the warping roll. The top of the inspection platform 1 is equipped with a transmissive light source backplate 12. The transmissive light source backplate 12 has the characteristics of high brightness and uniformity, stable color temperature during the shooting process, close to natural light without stray light, and no color shift interference. It assists the first CCD camera 11 in imaging, which can significantly reduce scanning imaging noise and improve imaging clarity. This improves the accuracy of surface damage analysis of the warping roller 13. A control cabinet 23 is set on the outside of the inspection platform 1. Several adjustment screw holes 14 are arranged on one side of the top of the inspection platform 1. The bottom structure of the warping roller support 2 set on one side of the top of the inspection platform 1 has a strip groove that can be aligned with the adjustment screw holes 14. A ring transmission mechanism 15 that is threadedly connected to the corresponding adjustment screw hole 14 is installed in the strip groove. This meets the requirements for adjusting the distance between the two warping roller supports 2 in subsequent use.

[0023] When using it, the scanning and detection of the surface of the warping roller 13 is carried out as follows; The first step is to fit both ends of the warping roller 13 into the other end of the composite support cylinder 31 inside the two clamping components 3 respectively. The two semi-open slots provide sufficient clearance. After completion, the two clamping plates 32 inside the two clamping components 3 are activated. The two clamping plates 32 in the relative position drive their respective first electric push rods 33 to clamp and position the ends of the warping roller 13. Thus, the assembly of the warping roller 13 before inspection is completed. The second step is to open the back plate 12 of the transmissive light source and start the first brake servo motor 52 inside the power mechanism 5. The first brake servo motor 52 drives the corresponding clamping component 3 to rotate synchronously through the reducer 51 and the T-shaped linkage shaft 53. Then, with the auxiliary support of the two warping roller supports 2 and another clamping component 3, the warping roller 13 will rotate at a constant speed according to the preset. The third step involves selecting a fixed scanning position, activating the second brake servo motor 8, which drives the first lead screw 7 to rotate, engaging the first nut seat 9. This causes the first nut seat 9 to move the longitudinal lead screw transmission mechanism 10 to the left or right until a suitable position is reached. The second brake servo motor 8 is then temporarily deactivated, and the third brake servo motor 104 inside the longitudinal lead screw transmission mechanism 10 is activated. The third brake servo motor 104 drives the second lead screw 102 to rotate, engaging the second nut seat 103. This causes the second nut seat 103 to move the first CCD camera 11 up and down until a suitable position is reached. The first CCD camera 11 is then activated, performing a fixed-point scan of the rotating warping roller 13. The relevant data is analyzed and processed by the image recognition device associated with the first CCD camera 11, as detailed below: The supporting software in the image recognition device includes a database that stores the contour data of warping rolls of various specifications, as well as software functions that receive scanned imaging data for comparison and analysis. It can determine the tolerance of damage of warping roll 13 according to the pre-set tolerance, and mark the damage exceeding the tolerance range to realize the damage detection of warping roll 13. At the same time, it can realize local data storage and cloud upload functions, and has the function of comparing multiple scan data. It can produce the wear curve of warping roll 13 cycle and realize the wear and maintenance early warning function of warping roll 13. In this example, as the first CCD camera 11 scans the groove contour of warping roll 13 and generates scan data in real time in the supporting software, it compares and analyzes with the standard contour to complete the damage detection of warping roll.

[0024] The fourth step is to select full scan and start the third brake servo motor 104 inside the longitudinal lead screw transmission mechanism 10. The third brake servo motor 104 drives the second lead screw 102 to rotate and engage the second nut seat 103, so that the second nut seat 103 drives the first CCD camera 11 to move up and down until the appropriate position is reached. The second brake servo motor 8 is activated, which drives the first lead screw 7 to rotate, engaging the first nut seat 9. This causes the first nut seat 9 to continuously displace the longitudinal lead screw transmission mechanism 10 from left to right. Simultaneously, the first CCD camera 11 is activated, capturing and scanning the rotating warping roller 13. The relevant data is then analyzed and processed by the image recognition device associated with the first CCD camera 11, as follows: In this example, as the first CCD camera 11 scans the groove contour of the warping roll 13 and generates scanning data in real time in the supporting software, the damage detection of the warping roll is completed by comparing and analyzing it with the standard contour. Fifth step: After the warping roller 13 is inspected, close the two clamping plates 32 inside the two clamping components 3 respectively. The two clamping plates 32 in the relative position drive the corresponding first electric push rods 33 to reset. Then, take out the warping roller 13 directly. The sixth step is that when faced with warping rollers 13 of different lengths, the spacing between the two warping roller supports 2 can be changed by locking the adjusting screw holes 14 at different positions with the annular transmission mechanism 15, thereby improving the detection range of the overall device.

[0025] like Figures 7-10 The output structure of the horizontal lead screw transmission platform can also be connected to a ring transmission mechanism 15. The output structure of the ring transmission mechanism 15 is connected to a second CCD camera 16. Under the transmission of the ring transmission mechanism 15, the second CCD camera 16 can take a full picture of the warping roller 13 clamped and limited by the two clamping components 3. The second CCD camera 16 can also be connected to the image recognition device associated with the first CCD camera 11 through wireless communication to meet the needs of subsequent real-time data analysis. The annular transmission mechanism 15 includes a composite annular support cylinder 151. A gear ring 152 and a second conductive slip ring 155 are respectively mounted on the inner side of the composite annular support cylinder 151 through bearings. A support plate connected to the housing surface of the second CCD camera 16 is fixed to one end face of the gear ring 152. A meshing output assembly is provided on the top of the composite annular support cylinder 151. The meshing output assembly includes a fourth brake servo motor 153 and a gear 154. The output end of the fourth brake servo motor 153 is connected to the gear 154 and enables the gear 154 to mesh with the gear ring 152. An auxiliary seat is installed between the housing surface of the fourth brake servo motor 153 and the top surface of the composite annular support cylinder 151 to ensure stability during subsequent continuous use. The front end of the bottom of the composite annular support cylinder 151 is installed on the top of the first nut seat 9, and a guide structure is provided between the rear end of the bottom of the composite annular support cylinder 151 and the top of the detection platform 1. The guide structure includes a guide seat 17, a guide rod 18 and a second positioning seat 19. The second positioning seat 19 is fixed on the top of the detection platform 1. The guide rod 18 is fixedly sleeved on the inner side of the middle of the second positioning seat 19 and is engaged with the guide seat 17. The rear end structure of the bottom of the gear 154 is connected to the top of the guide seat 17. Thus, the stability of the movement of the annular transmission mechanism 15 and the second CCD camera 16 during the reciprocating motion can be improved and correction protection can be provided through the guiding constraint of the guide structure, reducing the adverse factors on the second CCD camera 16's scanning. The bottoms of the two warping roller supports 2 are connected to a support slide rail 21 fixed on the top surface of the middle part of the inspection platform 1. On the other side of the top of the inspection platform 1, the warping roller support 2 is externally connected to a second electric push rod 20 installed on the other side of the top of the inspection platform 1. On the other side of the top of the inspection platform 1, a limiting plate 22 is fixed, which can press and limit the warping roller support 2 under the transmission of the second electric push rod 20. This allows one warping roller support 2 to move automatically to make way, which facilitates the subsequent disassembly of the warping roller 13.

[0026] In use, considering that the relatively long warping roller 13 vibrates significantly during rotation, which may affect the scanning of the first CCD camera 11, the warping roller 13 is inspected and processed through a ring-shaped transmission mechanism 15, a second CCD camera 16, and other structures. The specific operation is as follows: First, turn off the second electric push rod 20. The second electric push rod 20 drives the corresponding warping roller bracket 2 and clamping assembly 3 to move and make way. Start the second brake servo motor 8. The second brake servo motor 8 drives the first lead screw 7 to rotate and mesh with the first nut seat 9. Then the first nut seat 9 drives the annular transmission mechanism 15 to move to the right or left to the maximum stroke. First, one end of the warping roller 13 is fitted with a clamping assembly 3 and an annular transmission mechanism 15. Then, the second electric push rod 20 is activated, which drives the corresponding warping roller bracket 2 and clamping assembly 3 to move and reset, thereby completing the fitting of the warping roller 13 with the two clamping assemblies 3 and the annular transmission mechanism 15. Then, the two clamping plates 32 inside the two clamping assemblies 3 are activated, and the two clamping plates 32 in the relative position drive their respective first electric push rods 33 to clamp and position the end of the warping roller 13. Thus, the assembly of the warping roller 13 before inspection is completed. The second step is to open the back plate 12 of the transmissive light source and start the first brake servo motor 52 inside the power mechanism 5. The first brake servo motor 52 drives the corresponding clamping component 3 to rotate synchronously through the reducer 51 and the T-shaped linkage shaft 53. Then, with the auxiliary support of the two warping roller supports 2 and another clamping component 3, the warping roller 13 will rotate at a constant speed according to the preset. The third step involves selecting a fixed scanning position and activating the second brake servo motor 8. The second brake servo motor 8 drives the first lead screw 7 to rotate, engaging the first nut seat 9. This causes the first nut seat 9 to move the annular transmission mechanism 15 to the left or right until a suitable position is reached. The second brake servo motor 8 is then temporarily deactivated, and the second CCD camera 16 and the fourth brake servo motor 153 are activated. The fourth brake servo motor 153 engages with the gear ring 152 via gear 154, causing the gear ring 152 to drive the second CCD camera 16 to rotate reciprocally. This allows the rotating second CCD camera 16 to perform fixed-point scanning of the warping roller 13, and the relevant data is analyzed and processed by the image recognition device associated with the first CCD camera 11, as detailed below: The supporting software in the image recognition device includes a database that stores the contour data of warping rolls of various specifications, as well as software functions that receive scanned imaging data for comparison and analysis. It can determine the tolerance of damage of warping roll 13 according to the pre-set tolerance, and mark the damage exceeding the tolerance range to realize the damage detection of warping roll 13. At the same time, it can realize local data storage and cloud upload functions, and has the function of comparing multiple scan data. It can produce the wear curve of warping roll 13 cycle and realize the wear and maintenance early warning function of warping roll 13. In this example, as the second CCD camera 16 scans the groove contour of warping roll 13 and generates scan data in real time in the supporting software, it compares and analyzes with the standard contour to complete the damage detection of warping roll.

[0027] Step 4: Select full scan; The second brake servo motor 8 is activated, which drives the first lead screw 7 to rotate, engaging the first nut seat 9. This, in turn, causes the first nut seat 9 to continuously move from left to right, via the annular transmission mechanism 15 and the second CCD camera 16. Simultaneously, the second CCD camera 16 and the fourth brake servo motor 153 are activated. The annular transmission mechanism 15 rotates the second CCD camera 16, allowing it to scan and capture the warping roller 13. The data is then analyzed and processed by the image recognition device associated with the first CCD camera 11, as detailed below: In this example, as the first CCD camera 11 scans the groove contour of the warping roll 13 and generates scanning data in real time in the supporting software, the damage detection of the warping roll is completed by comparing and analyzing it with the standard contour. Fifth step: After the test is completed, start the second brake servo motor 8. The second brake servo motor 8 drives the first lead screw 7 to rotate, which in turn engages the first nut seat 9. This causes the first nut seat 9 to move the annular transmission mechanism 15 to the right or left to its maximum stroke. Then, hold the warping roller 13 and close the second electric push rod 20. The second electric push rod 20 drives the corresponding warping roller bracket 2 and clamping assembly 3 to move and make way. Then, close the two clamping plates 32 inside each of the two clamping assemblies 3. The two clamping plates 32 in the opposite position drive their respective first electric push rods 33 to reset. After completion, pull the warping roller 13 out of the annular transmission mechanism 15 and the remaining clamping assembly 3.
