Description

Technical Field

[0001] The invention relates to the technical field of cloth inspection machines, and in particular discloses an intelligent cloth inspection machine. Background Art

[0002] In the textile industry, fabric inspection machines are important equipment for inspecting fabric quality, identifying defects, recording fabric information, and grading. Traditional fabric inspection machines can be roughly divided into manual fabric inspection machines and semi-automatic fabric inspection machines. Manual fabric inspection machines mainly rely on manual visual inspection of fabric defects, which has low detection efficiency and is easily affected by human factors (such as fatigue and subjective judgment bias). Although semi-automatic fabric inspection machines can use basic photoelectric sensors to detect fabric defects, they lack intelligent analysis capabilities and still require human intervention to determine the type and severity of defects.

[0003] In the existing technology, some high-end cloth inspection machines have integrated basic automation devices, such as servo-driven detection systems, simple optical sensors and PLC control systems, but the following technical problems still exist: different factories and different operators have inconsistent judgment standards for cloth defects, resulting in unstable cloth inspection results, affecting the collaborative work of upstream and downstream supply chains; traditional cloth inspection machines usually require manual cloth threading, which is complicated and time-consuming to operate, affecting production efficiency; the existing detection system can only simply identify the defect location, but cannot combine intelligent algorithms to optimize the labeling location, and manual labeling is required, and the recognition accuracy and labeling accuracy are not high; the single-axis drive labeling system has a large positioning deviation, and does not solve the detection interference caused by cloth tension fluctuations and wrinkle deformation. In addition, the existing cloth inspection equipment is separated in the fabric transmission, defect identification, and precise marking links, making it difficult to achieve high-stability unmanned operation.

[0025] (2) Defect detection and precise marking: The detection device (second detection camera) combines a fill light and a lampshade to capture surface defects of the fabric. The mechanical arm device (first / second slide, lead screw and servo motor) drives the suction nozzle to accurately locate the defect and label it. The wrinkle detection device uses a curved cloth guide and camera combination to identify the deformed wrinkles of the fabric and trigger the flattening device for flattening.

[0026] (3) Dynamic feedback adjustment: The intelligent code recorder monitors the displacement distance of the fabric in real time through the meter wheel and the lifting mechanism. The tension detector links the main control system to adjust the speed of the unwinding roller to ensure constant fabric tension and reduce detection errors.

[0029] (2) AI dynamically optimizes detection accuracy: The algorithm library is combined with the data migration module to enable the machine to autonomously learn the manual cloth inspection standards, reduce the missed detection rate and adapt to diversified production needs, and solve the problem of parameter rigidity of traditional cloth inspection machines.

[0030] (3) Multi-dimensional collaborative inspection system: The defect detection and wrinkle detection systems complement each other, and the three-step flattening device (spiral reverse flattening roller) is combined to eliminate the interference of fabric deformation and improve the inspection accuracy; the intelligent code recorder and tension closed-loop control ensure the inspection position and tension stability.

[0031] (4) Modular expansion capability: The supply chain interface supports external device access, the algorithm library is expandable and compatible with new defect types, and the label transfer mechanism and robotic arm device are adaptable to labels of different sizes, enhancing the versatility of the equipment.

[0032] (5) Friendly human-computer interaction: The weight sensor and display screen display the weight of the fabric roll in real time. The opening and closing of the cloth clamping plate triggered by the first cylinder simplifies the manual intervention steps and reduces the complexity of the operation.

[0049] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0050] See also Figures 1 to 13As shown, the present invention provides an intelligent cloth inspection machine, including a frame 1, a cloth transmission system 2, a detection and marking system 3 and a main control system 4. Each system cooperates with each other to achieve efficient cloth inspection, intelligent analysis and automatic marking of cloth. The cloth transmission system 2 is composed of a reeling device 21, a reeling device 23 and an automatic cloth threading device 22. The reeling device 21 is responsible for carrying and releasing the cloth, the reeling device 23 collects the detected cloth, and the automatic cloth threading device 22 ensures that the cloth is smoothly and orderly transmitted from the reeling device 21 to the reeling device 23 to avoid uneven tension or wrinkles in the cloth.

[0051] The detection and marking system 3 is composed of a detection device 32, a mechanical arm device 31 and a labeling device 33. The detection device 32 is installed on the fabric transmission path between the unwinding device 21 and the rewinding device 23, scans the fabric surface in real time, identifies the defect position, and transmits the data to the main control system 4. The mechanical arm device 31 accurately locates according to the defect position information, and drives the labeling device 33 to mark the defect area to ensure the accuracy of the marking and reduce manual intervention. The present invention realizes high-precision and efficient intelligent fabric inspection through automated mechanical transmission, detection and marking devices, reduces manual dependence, improves production consistency, and provides real-time quality data support for the supply chain.

[0052] Specifically, the detection device 32 includes an arc-shaped cloth guiding platform 351 arranged on the frame 1, a first fill light 352 arranged on one side of the arc-shaped cloth guiding platform 351, and a first detection camera 353 arranged in cooperation with the first fill light 352. The arc-shaped cloth guiding platform 351 has an outer convex smooth arc surface for supporting the cloth guided by the cloth guiding mechanism. The first fill light 352 is used to emit straight light on the outer convex smooth arc surface. The first detection camera 353 is used to photograph the cloth supported by the outer convex smooth arc surface illuminated by the straight light. The main control system 4 receives the image taken by the first detection camera 353 and detects and analyzes whether the cloth has defects.

[0053] Specifically, the first fill light 352 uses a high-brightness LED line light source, which can emit stable straight light and illuminate the convex smooth curved surface of the arc-shaped cloth guide 351 at a specific angle. After the straight light is irradiated, a uniform light band will be formed on the surface of the fabric to enhance the visibility of the details of the fabric surface. The first detection camera 353 uses a high-resolution CMOS sensor and is equipped with an industrial-grade lens, which can accurately capture the surface image of the fabric after the straight light is irradiated. When there are defects in the fabric (such as broken yarn, holes, color difference or oil stains), it will affect the reflection characteristics of the straight light, which will appear as distortion, missing or color change of the light band in the camera imaging.

[0054] Specifically, after receiving the image from the inspection camera, the main control system 4 uses a deep learning algorithm (such as a CNN convolutional neural network) to classify the defect type and automatically trigger a marking or alarm mechanism based on the severity of the defect:

[0055] Minor defects (such as slight color difference): record the location data and store it in the inspection log;

[0056] Serious defects (such as large-area damage): trigger the automatic labeling device, attach defect labels to the corresponding fabric areas, and upload the data to the production management system.

[0057] If multiple serious defects are detected, the system can control the equipment to pause and prompt the operator to check.

[0058] Specifically, the first base 211 of the unwinding device 21 is fixed to the left side of the frame 1 through the ground support feet and is connected to the frame 1 without locking, which is convenient for subsequent maintenance and replacement. The unwinding bracket 212 is welded with H-shaped steel and is vertically fixed to the center of the base. The weight sensor 213 (model HBM PW15C3, range 0-500kg) is embedded in the installation groove between the base and the bracket, and is pre-tightened by four sets of M12 high-strength bolts to monitor the weight of the cloth roll in real time (accuracy ±0.1% FS). The two unwinding rollers 214 are connected to the unwinding bracket 212 through double-row tapered roller bearings, and the fourth drive motor 215 drives the unwinding rollers 214 to rotate through the gear synchronous belt mechanism. The weight display screen is embedded and installed on the top of the unwinding bracket 212, and communicates with the weight sensor 213 and the main control system 4 through the RS485 interface to display the roll weight, remaining length (through weight-density conversion) and unwinding speed in real time.

[0059] Specifically, in this embodiment, two slidable cloth baffles 216 are provided in the length direction of the unwinding bracket 212 (radial direction of the unwinding roller 214). In actual use, the distance between the two slidable cloth baffles 216 can be adjusted to adapt to cloths of different widths, thereby improving the compatibility of the cloth inspection machine.

[0060] Specifically, the cloth transmission system 2 further includes a tension control device 25 arranged in cooperation with the unwinding device 21, and the tension control device 25 includes a buffer space 251 arranged in the frame 1 and a tension detector 252 for detecting the cloth unwound by the unwinding device 21 in the buffer space 251; the buffer space 251 is arranged inside the frame 1, between the unwinding device 21 and the subsequent transmission path, and in this embodiment is designed as an S-shaped path (composed of a plurality of guide rollers 2223), and the cloth first enters this area after being unwound from the unwinding device 21. The function of the buffer space 251 is to absorb the tension fluctuation during the cloth transmission process.

[0061] In this embodiment, the tension detector 252 is an ultrasonic analog electric eye installed in the buffer space 251, which measures the stacking height of the cloth in the buffer space 251. When the cloth is stacked too much or too little, it reflects that the tension is insufficient or too large. It transmits the collected tension data or height data to the main control system 4. The main control system 4 analyzes the current cloth state according to the preset tension threshold and generates a control instruction.

[0062] When the tension detector 252 detects that the fabric tension is too large (or the stacking height is too low), it indicates that the unwinding speed is insufficient, and the main control system 4 instructs the fourth drive motor 215 to speed up the rotation speed, increase the fabric unwinding speed, and relieve the tension. When the tension detector 252 detects that the fabric tension is too small (or the stacking height is too high), it indicates that the unwinding speed is too fast, and the main control system 4 instructs the fourth drive motor 215 to slow down the rotation speed, reduce the fabric supply, and restore the tension to normal. Through closed-loop feedback control, the rotation speed of the fourth drive motor 215 can respond to the signal of the tension detector 252 in real time, ensuring that the fabric tension is always in the best state.

[0063] Specifically, the second base 230 of the winding device 23 is fixed to the right side of the frame 1 through supporting feet, and the winding bracket 231 is reciprocatingly arranged on the second base 230 via a transverse driving mechanism 232. Two winding rollers 233 are rotatably arranged on the winding bracket 231, and the fifth driving motor 234 is connected to the two winding rollers 233 via a gear synchronous belt mechanism.

[0064] The transverse driving mechanism 232 includes a roller bracket 2321 arranged on the second base 230, a roller member 2322 rotatably arranged on the roller bracket 2321, a rack 2323 arranged on the second base 230, a correction roller 2324 rollingly arranged on the roller member, and a sixth driving motor 2325 arranged on the correction roller 2324, the output end of the sixth driving motor 2325 is connected to a second gear 2326 meshing with the rack 2323, the sixth driving motor 2325 is electrically connected to a slot-type electric eye 2327, the slot-type electric eye 2327 is used to detect the offset of the cloth wound by the winding roller 233 and trigger the sixth driving motor 2325 to drive the winding bracket 231 to move back and forth in the radial direction of the winding roller 233 for correction.

[0065] Specifically, the automatic cloth threading device 22 includes a circulating cloth feeding mechanism 221 movably arranged on the frame 1, a cloth feeding transmission mechanism 222 connected to the circulating cloth feeding mechanism 221, and a cloth feeding drive mechanism 223 connected to the cloth feeding transmission mechanism 222; the circulating cloth feeding mechanism 221 includes a cloth clamping robot 224 for limiting one end of the cloth unwound by the unwinding device 21, and the cloth feeding drive mechanism 223 drives the cloth clamping robot 224 to move back and forth between the unwinding device 21 and the winding device 23 via the cloth feeding transmission mechanism 222.

[0066] Specifically, the cloth feeding transmission mechanism 222 includes a plurality of first gears 2221 rotatably arranged on the frame 1, an annular toothed belt 2222 meshing with the plurality of first gears 2221, and a guide roller 2223 rotatably arranged coaxially with the first gears 2221, and the plurality of first gears 2221 are spaced apart on the frame 1; the cloth feeding drive mechanism 223 includes a first driving motor connected to the first gear 2221, and the cloth clamping manipulator 224 is connected to the annular toothed belt 2222, and the annular toothed belt 2222 drives the cloth clamping manipulator 224 to reciprocate under the drive of the first driving motor to form an S-shaped moving path between the unwinding device 21 and the winding device 23. The cloth limited by the cloth clamping manipulator 224 is transferred to the winding device 23 at one end of the cloth unwound by the unwinding device 21 under the action of the cloth feeding drive mechanism 223 and the cloth feeding transmission mechanism 222 to realize the cloth threading operation. It replaces the traditional manual cloth threading operation and improves the efficiency by more than 80%.

[0067] Specifically, the cloth clamping manipulator 224 includes a moving plate 2241 fixedly mounted on the annular toothed belt 2222, a cloth clamping plate 2243 rotatably arranged on the moving plate 2241 via a torsion spring 2242, one end of the torsion spring 2242 is provided with a transmission bracket 2244, and the cloth clamping manipulator 224 also includes a first cylinder 2245 arranged on the frame 1, and the piston rod of the first cylinder 2245 is used to resist the transmission bracket 2244. When the moving plate 2241 is driven by the annular toothed belt 2222 to move downward, the cloth clamping plate 2243 is rotated by the torsion spring 2242. A transmission bracket 2244 is provided at one end of the torsion spring 2242. When the first cylinder 2245 is moved, the first cylinder 2245 drives its piston rod to contact the transmission bracket 2244, thereby compressing the torsion spring 2242 to make the cloth clamping plate 2243 away from the movable plate 2241. At this time, the operator can move one end of the cloth on the unwinding device 21 to between the movable plate 2241 and the cloth clamping plate 2243. Then the first cylinder 2245 drives the piston rod to reset, and the torsion spring 2242 resets to drive the cloth clamping plate 2243 to reset and clamp the cloth between the movable plate 2241 and the cloth clamping plate 2243. Then the cloth feeding drive mechanism 223 and the cloth feeding transmission mechanism 222 start to work, so that the cloth clamping manipulator 224 clamps one end of the cloth and guides it to the winding roller 233 of the winding device 23. The operator only needs to take off one end of the cloth and wrap it around the winding roller 233 to fix it.

[0068] Specifically, the robot arm device 31 includes a first driving mechanism 311 and a second driving mechanism 312, the first driving mechanism 311 includes a first slide rail 3112 arranged on the frame 1, a first slide 3113 slidably arranged on the first slide rail 3112, a first drag chain arranged on the first slide 3113 at one end, a first lead screw screwed to the first slide 3113, and a second servo motor connected to the first lead screw, the other end of the first drag chain is connected to the first slide rail 3112; the second driving mechanism 312 includes a second servo motor arranged on the first slide 3113 A slide rail 3121, a second slide table 3122 slidingly arranged on the second slide rail 3121, a second drag chain with one end arranged on the second slide table 3122, a second lead screw threadedly arranged on the second slide table 3122, and a third drive motor 3123 connected to the second lead screw, the other end of the second drag chain is connected to the second slide rail 3121; the labeling device 33 includes a suction nozzle part 331 arranged on the second slide table 3122 and a cylinder part connected to the suction nozzle part 331, and the moving direction of the first slide table 3113 is cross-arranged with the moving direction of the second slide table 3122.

[0069] Specifically, the first slide 3113 moves horizontally along the X axis (stroke 1.5m), and the second slide 3122 moves vertically along the Y axis (stroke 0.5m), and the two axes are linked to achieve any trajectory in the plane; the robot arm device 31 realizes large-scale, high-precision, and multi-material automated labeling operations through a double-layer orthogonal slide structure and a high-dynamic servo system. The combination of its rigid guide rail and lightweight design takes into account both speed and stability.

[0070] Specifically, the labeling device 33 also includes a label transfer mechanism 332, which includes a label placing wheel 3321 rotatably arranged on the first slide 3113 via a mounting plate 3320 for unrolling external labels, a label track 3322 coordinated with the label placing wheel 3321, a label feeding roller 3323 rotatably arranged on one side of the label track 3322, and a paper receiving wheel 3324 rotatably arranged on the other side of the label track 3322. The label unrolled by the label placing wheel 3321 is flattened to the label track 3322 via the label feeding roller 3323, and the air source module is used to drive the suction nozzle 331 to absorb the label on the label track 3322 and attach it to the defective position of the fabric under the coordinated action of the robot arm device 31 and the detection device 32.

[0071] Specifically, a peeling guide slope (chamfer angle 35°, surface roughness Ra≤0.8μm) is provided at the end of the label track 3322 (adjacent to the opposite end of the paper receiving wheel 3324). When the composite label belt (including spaced labels and continuous backing paper) moves along the track driven by the label feeding roller 3323 and the paper receiving wheel 3324, the backing paper and the label diverge at the peeling guide slope. The backing paper is pulled by the paper receiving wheel 3324, moves downward close to the guide slope and changes its direction of movement. The combined force direction of its surface tension and the label adhesion force suddenly changes, resulting in shear stress at the bonding interface between the label and the backing paper. Due to the label spacing distribution (spacing L≥2mm), only the blank area of ​​the backing paper contacts the guide slope when it moves downward. The label is automatically separated from the backing paper due to elastic deformation due to the suspension of the unsupported section. The separated label enters the picking station after inertial sliding of about 3-5mm at the end of the track, which is convenient for the suction nozzle 331 to pick up.

[0072] Specifically, the detection and marking system 3 also includes an intelligent code recorder 34 arranged between the unwinding device 21 and the winding device 23, and the intelligent code recorder 34 includes a lifting mechanism 341 arranged on the frame 1, a meter wheel 342 arranged at the output end of the lifting mechanism 341 for contacting the cloth, a code recorder 343 coaxially connected to the meter wheel 342, and a first position sensor 344 electrically coordinated with the lifting mechanism 341; the first position sensor 344 is used to detect the position information of one end of the cloth transferred by the automatic cloth threading device 22, and trigger the lifting mechanism 341 to drive the meter wheel 342 to move forward to contact the cloth, and when the first position sensor 344 does not detect the cloth, it triggers the lifting mechanism 341 to drive the meter wheel 342 to move reversely and reset.

[0073] The lifting mechanism 341 includes a second cylinder, which is electrically matched with the first position sensor 344. When the sensor detects that the cloth has arrived, the second cylinder drives its piston rod to press down the meter wheel 342 (the surface is covered with anti-slip rubber) to close to the cloth, and rotates synchronously with the movement of the cloth. Its coaxial encoder 343 converts the number of rotations into length data; after the cloth has moved, the sensor signal disappears, and the lifting mechanism 341 automatically lifts the meter wheel 342 to reset. This design ensures metering accuracy (error ≤ 0.05%) and avoids manual intervention through contact pressure control and real-time data feedback, and integrates a reset protection mechanism to prevent equipment idling damage.

[0074] In this embodiment, the arc-shaped cloth guide 351 is composed of two guide rollers 2223, wherein the central axis of one guide roller 2223 is located obliquely above the central axis of the other guide roller 2223. An antistatic coating is added to the surface of the arc-shaped cloth guide 351 to reduce the tiny wrinkles of the cloth caused by electrostatic adsorption and improve the detection accuracy. The first fill light 352 is located on one side of the arc-shaped cloth guide 351 and adopts an LED light source with an adjustable angle to provide uniform detection illumination to avoid affecting the accuracy of wrinkle recognition due to different reflective properties of the cloth. The brightness of the fill light can be dynamically adjusted according to the material of the cloth (such as smooth silk, cotton and linen fabrics, etc.) to adapt to different detection environments.

[0075] The first detection camera 353 is installed on the opposite side of the first fill light 352, parallel to the curved cloth guide 351, responsible for capturing the surface image of the cloth in real time, and uploading it to the main control system 4 to identify wrinkle defects through image processing algorithms. The camera is a high-resolution industrial camera, and integrates image processing algorithms such as edge enhancement, contrast optimization, and surface correction to ensure accurate identification of tiny wrinkles and defects. The second position sensor 354 is installed on the other side of the curved cloth guide 351, used to detect the real-time position of the cloth in the detection area, and electrically cooperates with the main control system 4. When the cloth enters the detection area, the sensor triggers the first detection camera 353 to start shooting, and at the same time detects the tension and displacement of the cloth to ensure that the camera captures complete wrinkle and defect data.

[0076] Specifically, the cloth transmission system 2 further includes a cloth flattening device 26, which includes a flattening roller 261 rotatably disposed on the frame 1 and two flattening members 262 spirally wound around the flattening roller 261, and the spiral directions of the two flattening members 262 are opposite. In this embodiment, the flattening roller 261 is driven by a separate seventh drive motor 263, and the seventh drive motor 263 is electrically connected to the first detection camera 353.

[0077] When the cloth enters the cloth transmission system 2 from the unwinding device 21, it passes through the automatic cloth threading device 22 and reaches the wrinkle detection device. The second position sensor 354 detects that the cloth has reached the arc-shaped cloth guide table 351, and sends a signal to the main control system 4, triggering the first fill light 352 and the first detection camera 353 to start. The first fill light 352 provides uniform illumination, and the first detection camera 353 photographs the cloth surface and identifies the wrinkle area through the AI ​​algorithm. After identifying the wrinkle defect, the main control system 4 adjusts the flattening force of the cloth flattening device 26 according to the severity of the wrinkle, and controls the robot arm device 31 and the labeling device 33 to mark the defect position according to the defect position. If the cloth tension is abnormal, the main control system 4 can optimize the cloth conveying tension by adjusting the speed of the fourth drive motor 215 of the unwinding device 21 or the speed of the fifth drive motor 234 of the winding device 23. After the processing is completed, the cloth continues to enter the defect detection system for subsequent detection and labeling.

[0078] The arc-shaped cloth guide 351 provides uniform lighting, combined with AI image analysis, to improve the accuracy of wrinkle defect recognition; the brightness of the fill light, the camera focal length and the angle of the arc-shaped cloth guide 351 can be dynamically adjusted, suitable for cloths of different thicknesses and materials. After wrinkles are detected, the flattening force of the cloth flattening device 26 is automatically adjusted to make the cloth flatter when it enters the defect detection link, improving the quality of subsequent detection and winding.

[0079] Specifically, the frame 1 is provided with a plurality of tension rollers 24 (in this embodiment, the tension rollers 24 are guide rollers 2223) rotatably disposed between the unwinding device 21 and the winding device 23, and the detection device 32 includes a detection platform 321 located between two adjacent tension rollers 24, a second fill light 322 disposed on the detection platform 321, a lampshade 3221 disposed above the detection platform 321 and the second fill light 322, and a second detection camera 323 disposed above the detection platform 321, and the second detection camera 323 is electrically coordinated with the robot device 31 and the labeling device 33 via the main control system 4. The lampshade 3221 is integrated with a control panel electrically connected to the second fill light 322, for adjusting parameters such as the brightness and irradiation angle of the light.

[0080] The second detection camera 323 is used to take a second picture of the fabric image and upload it to the main control system 4 for analysis to ensure the detection accuracy.

[0081] The tensioning roller 24 is arranged on the frame 1 and installed between the unwinding device 21 and the winding device 23. Its main function is to stabilize the tension of the fabric, keep the fabric flat in the defect detection area, and reduce the detection error caused by fabric swinging or loosening. The setting of multiple tensioning rollers 24 can ensure that the fabric does not wrinkle or stretch during the transmission process, thereby ensuring the accuracy of the detection. The detection platform 321 is set between two adjacent tensioning rollers 24, and its surface is made of high-reflectivity material or optical diffuse reflection coating to optimize the reflection effect of the light source and make the light distribution in the detection area more uniform. When the fabric passes over the detection platform 321, the platform can provide a stable background contrast to improve the detection accuracy.

[0082] The second fill light 322 is installed above the detection platform 321 to provide a stable light source and improve the imaging quality of the detection camera. The second fill light 322 uses a high-brightness LED light source and can automatically adjust the brightness according to the color and material of the fabric to ensure uniform detection. The irradiation angle of the light source is optically optimized to avoid reflections or shadows caused by direct light. The lampshade 3221 is installed above the detection platform 321 and the fill light to control the irradiation range of the light source, reduce ambient light interference, and improve detection stability. The interior of the lampshade 3221 uses an anti-reflective coating to ensure that the light is evenly distributed in the detection area.

[0083] The second detection camera 323 is installed above the detection platform 321 to photograph the surface of the fabric and identify defects through high-resolution image processing technology. The camera can capture the details of the fabric surface in real time through an industrial-grade CMOS sensor, and analyze the defect type (such as broken yarn, color difference, oil stains, damage, etc.) in combination with an AI algorithm. The camera is connected to the main control system 4 and transmits the defect information to the robot arm device 31 and the labeling device 33 for marking.

[0084] Specifically, when the fabric processed by the wrinkle detection device is transmitted to the detection area, after the tension is adjusted by the tension roller 24, it passes smoothly through the detection platform 321; the second fill light 322 provides a uniform light source to ensure that the fabric surface is evenly illuminated without shadows or reflections; the second detection camera 323 takes a picture of the fabric surface and transmits the image data to the main control system 4; then the main control system 4 analyzes the image, identifies the defect type, and sends instructions to the robot device 31; the robot device 31 drives the labeling device 33 to attach a label to the detected defect position to complete automatic marking. The detection data can be uploaded to the AI ​​collaborative system and shared with the supply chain to improve the efficiency of quality control and production management.

[0085] The intelligent cloth inspection machine of the present invention realizes efficient cloth inspection, intelligent analysis and automatic marking of cloth through the cooperation of cloth transmission, automatic labeling and intelligent winding systems. Its working process is as follows:

[0086] First, the cloth unwinding device 21 carries and releases the cloth to ensure that the cloth enters the cloth inspection process stably. The weight sensor 213 monitors the weight of the cloth roll in real time, and communicates with the main control system 4 through the RS485 interface to calculate the remaining length of the cloth and the unwinding speed. The tension control device 25 is provided with a buffer space 251 inside the frame 1 to form an S-shaped path, which is composed of a plurality of guide rollers 2223, and is used to buffer the fluctuation of cloth tension and avoid wrinkles or breaks during the cloth transmission process. The ultrasonic analog electric eye in the buffer space 251 monitors the cloth stacking height and feeds back to the main control system 4. If the tension is too large or the cloth supply is insufficient, the main control system 4 controls the fourth drive motor 215 to speed up the unwinding speed; if the tension is too small or the cloth is too much, the unwinding speed is slowed down to ensure that the cloth conveying tension is always in the best state.

[0087] After entering the detection area, the straight light generated by the first fill light 352 will form a uniform light band on the surface of the fabric to enhance the visibility of the details on the surface of the fabric. The first detection camera 353 uses a high-resolution CMOS sensor and an industrial-grade lens to accurately capture the surface image of the fabric after being illuminated by the straight light. When there are defects in the fabric (such as broken yarn, holes, color difference or oil stains), it will affect the reflection characteristics of the straight light, which will appear as distortion, missing or color change of the light band in the camera imaging.

[0088] After receiving the image from the inspection camera, the main control system 4 uses a built-in deep learning algorithm (such as a CNN convolutional neural network) to classify the defect type and automatically trigger a marking or alarm mechanism based on the severity of the defect.

[0089] The automatic cloth threading device 22 replaces manual operation to ensure that the cloth is automatically guided to the winding device 23. The cloth clamping manipulator 224 is driven by a cylinder to clamp the cloth and transfer it to the winding device 23 through the ring toothed belt 2222. The cloth feeding drive mechanism 223 drives the cloth clamping manipulator 224 to run along the S-shaped track, transferring the cloth from the unwinding device 21 to the winding device 23, and finally the operator manually fixes the cloth on the winding roller 233. This process reduces manual intervention, improves the automation of cloth transportation, and improves the cloth threading efficiency by more than 80%.

[0090] When the cloth enters the secondary inspection area, the second inspection camera (323) of the inspection device 32 starts working. The cloth is transmitted through the tensioning roller 24 to ensure that the cloth remains flat on the inspection platform 321 to prevent swinging or tension changes from affecting the inspection accuracy. The second fill light 322 provides a uniform light source to optimize the imaging quality and can automatically adjust the brightness according to the cloth material. The second inspection camera 323 photographs the surface of the cloth and analyzes defects through the AI ​​algorithm, including broken yarn, color difference, oil stains, damage, etc. The AI ​​algorithm is trained based on the manual cloth inspection standard, can accurately identify different types of defects, and send defect location information to the main control system 4. The main control system 4 calculates the defect coordinates and instructs the robotic arm device 31 to accurately locate the defect location. The secondary inspection system further ensures the accurate marking of the defect location and improves the quality of cloth inspection.

[0091] After receiving the defect location information, the labeling device 33 automatically performs the marking operation. The robot arm device 31 adopts a double-layer slide structure, combined with a high-dynamic servo system, to achieve precise positioning of the X-axis and Y-axis. The labeling mechanism automatically peels off the label through the peeling guide slope, and the pneumatic suction nozzle picks up the label and attaches it to the defect area. The labeling process is combined with AI detection data to ensure that the label is attached accurately and the label is clearly marked, thereby improving the efficiency of subsequent production links.

[0092] The winding device 23 ensures that the fabric is neatly wound and performs real-time deviation correction. The slotted electric eye 2327 detects whether the fabric is offset during the winding process, and triggers the servo motor to drive the winding bracket 231 to fine-tune the position in the radial direction so that the fabric is arranged neatly. The winding roller 233 is driven by the fifth drive motor 234 to ensure that the fabric is wound with constant tension. The meter wheel 342 records the length of the fabric, and converts the data through the encoder 343 and uploads it to the AI ​​collaborative system to achieve accurate storage of production data.

[0093] The present invention realizes an efficient, high-precision and standardized cloth inspection process through technologies such as automated cloth transmission, automatic labeling and intelligent winding. The whole system works in coordination, so that the whole process from unwinding to winding of cloth does not require human intervention, greatly reducing human errors, improving production consistency, and providing an intelligent quality control solution for the textile industry.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
