Description

Technical Field

[0001] The present invention relates to the technical field of detection systems, and in particular to an intelligent textile defect detection system based on Internet of Things technology and a process thereof. Background Art

[0002] Textile defect detection is a key link in improving textile quality. Through detection, surface quality problems can be discovered and dealt with in a timely manner, thereby improving the overall quality and market competitiveness of products. Detection methods mainly include manual detection and machine vision detection. Although manual detection is easy to operate, it is time-consuming and has low accuracy; while machine vision detection uses computer vision technology to capture images of the fabric surface in real time through a camera and compare them with the standard. It has the advantages of fast speed and high accuracy, but the equipment cost is relatively high.

[0003] Defect detection mainly relies on visual inspection and measurement technology. Visual inspection technology takes pictures of the cloth through a camera, and then uses image processing technology to identify the location and size of the defect. Measurement technology is used to measure the size and location of the defect in order to assess its severity and impact. In addition, some advanced defect detection technologies can also use machine learning and artificial intelligence algorithms to classify and identify defects, improving the accuracy and efficiency of detection.

[0004] Defect detection process, sample preparation: select a batch of cloth samples to be tested to ensure that the quality and quantity of the samples meet the requirements. Photo and image processing: use a camera to take pictures of the cloth, and then use image processing technology to identify the location and size of the defects. Defect measurement: measure the size and location of the defects, and evaluate their severity and impact. Result output: output the test results to the relevant departments or customers so that appropriate treatment measures can be taken.

[0005] Defect detection method: Manual detection: Use manual visual detection to observe the defect location and size of the cloth, classify and record. Although this method is low-cost, the detection efficiency is not high and it is easily affected by subjective factors. Automated detection: Use automated equipment for detection, and use machine vision technology and measurement technology to achieve automatic detection and classification of cloth. This method has high detection efficiency and good accuracy, but requires a high cost. Joint detection: Combine manual detection and automated detection, and use different detection methods according to different situations to improve the accuracy and efficiency of detection.

[0006] ‌The application of machine vision technology in textile defect detection has made significant progress. ‌The textile defect detection system consists of a high-precision linear array camera, a linear array LED light source, detection software, an algorithm model and a high-performance computer. The system can detect defects such as holes, color spots, broken warps and wefts, etc., both facing and through light, and has the characteristics of high detection accuracy and low false alarm rate. The system is suitable for factories with a single variety and large production batches. It can significantly improve the detection speed and accuracy, and reduce the risk of manual missed detection and customer complaints.

[0007] ‌Textile defect detection has a wide range of applications, including textile, clothing and home textile industries. ‌In the textile industry, it can monitor problems such as yarn breakage and hairiness; in the clothing industry, it is used to check the quality of accessories such as buttons and zippers; in the home textile industry, it is used to check the quality of products such as bedding and curtains. In short, cloth defect detection is an important link in the textile industry and needs to be strictly tested and managed in accordance with requirements. By adopting advanced detection technologies and methods, the accuracy and efficiency of detection can be improved, thereby ensuring the quality and reputation of the cloth.

[0008] For example, the application number 202322425854.1 discloses a textile defect detection platform, which belongs to the field of textile detection technology. It mainly includes: a bracket and a turning assembly, on which a first conveyor belt and a second conveyor belt are respectively installed, and a gap is formed between the first conveyor belt and the second conveyor belt. In a textile defect detection platform of the present application, a user can place multiple textiles on the first conveyor belt, and the textiles can be clamped by the turning assembly to ensure the stability of the textiles moving on the first conveyor belt, and then the textiles are brought from the first conveyor belt to the second conveyor belt by the turning assembly, and the textiles are turned over. At the same time, the first visual camera and the second visual camera take pictures of both sides of the textile respectively, thereby realizing continuous automatic turning over and automatic detection of multiple textiles, avoiding frequent manual replacement of textiles by staff, reducing manual labor, improving detection efficiency, and improving the degree of production automation.

[0009] However, most of the current textile defect detection systems have problems such as the shaking of the cloth roller due to the pulling force during the cloth detection process, which often causes the cloth tension to be disturbed due to the cloth roller continuing to rotate due to inertia when the detection is suspended; conventional single-sided detection has low detection efficiency, complicated detection procedures, long detection time, high detection cost, high labor cost, manual on-site detection and marking, unsatisfactory detection effect, and difficulty in forming quality data; conventional automated detection equipment does not level and tighten the sides of the cloth before defect inspection, which often causes defect detection due to uneven corners and identifies this as a defect point, resulting in inaccurate detection data, affecting the validity of product quality data. Summary of the invention

[0010] The technical problem to be solved by the present invention is to solve the problem that during the cloth detection process, the cloth roller shakes due to the pulling force, which causes the cloth roller to continue to rotate due to inertia when the detection is suspended in the middle, causing cloth tension disorder; to improve the conventional single-sided detection method, improve the detection efficiency, reduce the detection process, reduce the detection time, reduce the detection cost, replace manual on-site detection and marking, reduce labor costs, improve the detection effect, and easily form quality data; optimize the conventional automatic detection equipment, level and tighten the side of the cloth before defect inspection, so as to solve the problem that the defect detection caused by uneven edges and corners is identified as a defect point, resulting in inaccurate detection data and affecting the validity of product quality data.

When the inspection is completed, the roller seat cylinder extends, drives the auxiliary roller away from the cloth outlet roller, and lifts out the cloth outlet roller; Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a portable cloth loading mechanism, the cloth roller for inspection can be easily replaced. It can be directly lifted and replaced, saving labor costs. The design of auxiliary support wheels, articulated arms, triangular positioning seats, and auxiliary support pressure wheels avoids the shaking of the cloth roller due to pulling force during the cloth inspection process. At the same time, the friction load of the cloth roller is increased to reduce the cloth tension disorder caused by the continuous rotation of the cloth roller due to inertia when the inspection is suspended midway.

[0013] 2. By setting up a front defect detection mechanism and a back defect detection mechanism, defect detection can be performed on both sides of the textile at the same time in one detection, thereby improving detection efficiency, reducing detection procedures, reducing detection time, and reducing detection costs. Through the design of the defect detection mechanism in conjunction with the defect marking mechanism, after defect detection, the system identifies the defect position. In addition to feeding back to the system terminal and providing detection image data, the defect position is physically marked by the defect marking mechanism, thereby improving the intelligence of the equipment, reducing manual on-site detection and marking actions, and improving the information level of the equipment.

[0014] 3. The accuracy of defect detection is improved by setting up a visual inspection camera, an industrial lens, a lens adjustment seat, a U-shaped groove, and a lighting lamp. The shooting and focusing of the visual inspection camera can be adjusted by adjusting the industrial lens. Combined with the cooperation of the ring lighting lamp, the ability to identify surface defects of the cloth is greatly improved, and the accuracy of defect detection is improved.

[0015] 4. By setting the first cloth feed support roller, the first cloth outlet support roller and the first cloth feed support plate, the stability of cloth batch operation during defect detection is effectively improved. At the same time, a stable downward pressure platform is provided for the defect marking mechanism, thereby improving the accuracy and freshness of the marking.

[0016] 5. By setting the first and second direction-changing rollers, the running direction of the detected cloth is effectively changed, which ensures the effective detection work while reducing the floor space of the equipment and improving the intensiveness of the equipment.

[0017] 6. By setting up a cloth feeding edge straightening mechanism, the cloth can be leveled and tightened on the sides before defect inspection, and the cloth can be flattened with the active roller and pressure roller to prevent defect detection caused by uneven edges and corners from being identified as defect points, resulting in inaccurate test data and affecting the validity of product quality data.

[0018] 7. By setting the cloth discharging mechanism on the same side as the cloth loading mechanism, the process path is reduced and the work efficiency is improved. The friction between the auxiliary roller and the cloth discharging roller drives the cloth discharging roller to rotate, making it easier to unload the cloth, thereby improving the degree of automation of the equipment.

[0019] 8. By setting up an image display, the images and data of the defect detection mechanism and the defect marking mechanism can be displayed on-site. At the same time, the data can be remotely fed back to the office computer online in real time to generate a quality data report, which can not only meet the on-site viewing of on-site management, but also realize remote office data viewing, thereby improving the intelligence of the equipment.
