Description

Technical Field

[0001] This invention belongs to the field of defect detection technology, and in particular relates to an intelligent identification and detection device for defects in clothing fabrics. Background Technology

[0002] In the quality inspection stage of garment production, fabric defect detection is a key process to ensure product quality. Currently, the mainstream detection methods still rely on manual visual inspection or traditional optical inspection equipment, which has many pain points that need to be addressed. Manual inspection is affected by subjective factors such as fatigue and experience, resulting in a high rate of missed detection of small defects such as yarn defects and hidden holes. In addition, it requires manual turning over and opening of pockets for inspection, which is inefficient and difficult to adapt to the needs of mass production. Although traditional optical inspection equipment has achieved partial automation, it mostly uses visual sensors with fixed angles and lacks angle adjustment and full-range movement mechanisms. There are obvious blind spots in areas such as the sides of shorts and the inside of pockets. Furthermore, there is no precise fabric tensioning mechanism, and wrinkles can easily cover up defects or create false defects, leading to frequent misjudgments and limited detection accuracy.

[0003] Meanwhile, existing equipment lacks a flexible adaptation and adjustment mechanism. Special clamps need to be replaced for shorts with different leg widths, and it is even more difficult to hold styles with hanging ornaments on the leg openings stably, resulting in extremely poor adaptability. Moreover, the clamping and support components are mostly rigid designs, which can easily cause fabric damage and are not practical enough. In addition, the visual sensors of traditional equipment lack intelligent collaborative detection capabilities and cannot work with mechanical mechanisms to achieve targeted detection of hidden areas, further limiting the detection accuracy and scope of application.

[0036] The operating principle of the present invention is described as follows:

[0037] During the initial detection phase, the device first uses the support flipping component 5 to position and fix the shorts and flatten the fabric, providing a stable detection benchmark for optical detection (avoiding detection errors caused by wrinkles).

[0038] The control third electric slide rail 54 is started, driving the two third slide plates 55 to move synchronously in opposite directions along the inner wall of the second groove 53, so that the distance between the two mounting rods 57 is precisely matched with the distance between the two legs of the shorts to be tested, ensuring that the legs can be stably fitted.

[0039] The staff puts the shorts on the outside of the two mounting rods 57, so that the waistband faces the third slide plate 55; then the second electric telescopic rods 59 in each third groove 58 are controlled to extend synchronously, driving the first support plate 510 to fit against the inner wall of the leg. Through the radial support of multiple sets of first support plates 510, the leg of the shorts and the surface fabric of the main body are kept taut, eliminating natural wrinkles.

[0040] Then, the third electric telescopic rod 514 and the fifth electric telescopic rod 518 are extended synchronously, driving the second clamping plate 519 and the U-plate 523 to move, so that the center of the opening of the U-plate 523 is aligned with the corresponding position of the waistband and leg end of the shorts; then the fourth electric slide rail 512 and the fifth electric slide rail 516 are activated, driving the fourth sliding plate 513 and the fifth sliding plate 517 to move the U-plate 523 towards the waistband and leg end until the U-plate 523 completely covers the corresponding part; the fourth electric telescopic rod 524 is extended, driving the clamping plate 525 to clamp and fix the waistband and leg end; the fourth electric slide rail 512 and the fifth electric slide rail 516 are activated in the opposite direction, driving the U-plate 523 to move outward, realizing the longitudinal stretching of the shorts, so that the entire surface of the fabric reaches a uniform tight state, providing a clear imaging carrier for optical detection;

[0041] For shorts of different sizes or with hanging accessories at the hem, the fourth motor 56 is started to drive the mounting rod 57 to rotate, adjusting the clamping position of the clamping plate 525 to ensure that the clamping plate 525 only contacts the fabric, avoiding interfering parts such as hanging accessories, and ensuring clamping stability and fabric integrity.

[0042] The intelligent optical inspection module, built using the first vision sensor 313, achieves full-dimensional detection of defects on the outer surface of the shorts through angle adjustment, position movement, and intelligent image analysis.

[0043] Intelligent calibration of detection angle: ① Start the first motor 37 to drive the first electric telescopic rod 38 to rotate, initially adjusting the pitch direction of the first vision sensor 313; ② Start the second motor 311 to drive the first round rod 310 to rotate, which in turn drives the first vision sensor 313 to rotate around the axis of the first round rod 310 through the side rod 312, so that the sensor detection end (lens) is perpendicular to the surface to be detected, ensuring no perspective distortion during imaging and improving the accuracy of defect recognition; ③ The intelligent calibration module built into the first vision sensor 313 automatically acquires the reference image and completes the adaptive adjustment of white balance and focal length;

[0044] Precise control of detection distance: Activate the extension and retraction of the first electric telescopic rod 38 to drive the first vision sensor 313 to move towards the surface of the shorts to a preset detection distance (this distance is adaptively matched by the sensor's built-in algorithm according to the fabric texture density), so that the sensor can clearly capture the detailed features of the fabric such as yarn texture and color distribution.

[0045] Full surface coverage inspection: ① Activate the first electric slide rail 33 and the second electric slide rail 35 to drive the first slide plate 34 and the second slide plate 36 to move along the horizontal XY axis, thereby driving the first vision sensor 313 to collect full-coverage images of the shorts surface according to a preset path (such as a serpentine scanning path); ② The intelligent analysis unit built into the first vision sensor 313 compares the collected images with the preset standard fabric texture database in real time, and identifies defects such as holes, skipped stitches, missing yarns, stains, and color variations through features such as grayscale differences, texture abrupt changes, and color anomalies, and simultaneously marks the coordinate position and type of the defects; ③ During the inspection process, the sensor provides real-time feedback on the image clarity data. If blurring occurs, the first electric telescopic rod 38 is automatically triggered to fine-tune the detection distance to ensure the continuity of the inspection.

[0046] Taking advantage of the highly concealable nature of the pocket's internal fabric, the internal detection component 6 drives the second vision sensor 615 deep into the pocket, combining tensioning and multi-angle scanning to achieve comprehensive detection without blind spots.

[0047] Detection end positioning and insertion: ① Activate the sixth electric slide rail 62 and the sixth electric telescopic rod 65 to drive the sixth slide plate 63, L rod 64 to move the side block 66 and the insertion rod 68, so that the axis of the insertion rod 68 is aligned with the center of the shorts pocket opening; ② Activate the seventh electric telescopic rod 616 to extend, drive the insertion rod 68 to slowly insert into the pocket. During the insertion process, the second vision sensor 615 collects the image of the pocket opening in real time, and the edge recognition algorithm ensures that the insertion rod 68 extends along the central axis of the pocket to avoid scratching the fabric;

[0048] Tight support for the inner wall of the pocket: Activate the eighth electric telescopic rod 610 to extend, drive the second support plate 611 to fit against the inner wall of the pocket, and make the inner fabric of the pocket tight through the radial support of multiple sets of second support plates 611, eliminate the wrinkles of the inner wall, and provide a clear view for internal imaging.

[0049] Internal full-dimensional inspection: ① The seventh electric slide rail 613 is activated to drive the seventh sliding plate 614, which in turn moves the second vision sensor 615 along the axis of the insertion rod 68 to perform axial scanning imaging of the inside of the pocket; ② The sixth motor 67 is activated to drive the seventh electric telescopic rod 616 to rotate, which in turn drives the insertion rod 68 and the second vision sensor 615 to rotate around the axis, achieving full coverage inspection of the inner wall of the pocket; ③ The second vision sensor 615 uses the same intelligent analysis algorithm as the first vision sensor 313 to identify hidden yarn defects, local damage, and other defects that may exist inside the pocket, marks the defect information, and uploads it to the system; ④ After the inspection is completed, the second support plate 611 is first controlled to retract, and then the seventh electric telescopic rod 616 and the sixth electric telescopic rod 65 are driven to remove the insertion rod 68 from the pocket to avoid taking out the fabric.

[0050] By supporting the flipping and resetting action of the flipping component 5, full coverage detection of the inner and outer surfaces of the shorts is achieved, avoiding the inefficiency and detection omissions caused by manual flipping:

[0051] Top and bottom surface flipping inspection: ① After completing the inspection of the top surface of the shorts and the corresponding pocket, control the first vision sensor 313 and the second vision sensor 615 to reset; ② Start the third motor 52 to drive the support rod 4 to rotate 180° around its axis, driving the mounting block 51 and the shorts to flip synchronously, so that the original bottom surface of the shorts faces upward; ③ Repeat the above surface inspection and pocket inspection process to complete the defect inspection of the bottom surface of the shorts and the pocket on the other side.

[0052] Inner and outer surface flipping inspection: ① After completing the full inspection of the outer surface, control the first support plate 510 and clamping plate 525 to retract, keeping the shorts fitted on the mounting rod 57; ② Start the fourth electric slide rail 512 and the fifth electric slide rail 516 to drive the fourth slide plate 513 and the fifth slide plate 517 to move in opposite directions. At the same time, start the fifth motor 521 on the side of the third electric telescopic rod 514 and the fifth electric telescopic rod 518 to drive the second round rod 520 to rotate 180° in the opposite direction of movement. Through the coordinated action of the U plate 523 and the clamping plate 525, the shorts are flipped along the axis of the mounting rod 57, so that the inner side of the shorts faces outward; ③ Control the first support plate 510 and clamping plate 525 to extend and fix them again, so that the inner side material is taut; ④ Repeat the surface inspection process to complete the defect inspection of the inner side material of the shorts.

[0053] After the full-dimensional inspection is completed, the system automatically summarizes the detection data of the first vision sensor 313 and the second vision sensor 615 to generate a defect detection report (including information such as location, type, and size); then controls the reset of each electric telescopic rod, electric slide rail, and motor, the clamp 525 is released, the staff removes the shorts, and the device enters the preparation state for the next round of inspection.
