In recent years, non-woven fabrics have been widely used in various aspects of industrial, commercial, corporate, and residents, and it is very important in the role played in modern industrial production. It is produced by high temperature melting, spinning, spreading, and hot pressing. It is called the fabric and certain performance of the cloth. Non-woven fabric is a new generation of environmentally friendly materials, with strong powerful, breathable waterproof, environmental protection, flexible, non-toxic and tasteless, and cheap. The surface of the non-woven fabric seriously affects the quality of the product itself, how to avoid the surface of the non-woven fabric, the quality control has always been the biggest problem facing manufacturers, the traditional artificial testing cost is expensive, the test personnel are easy to fatigue and easy to test Waiting for the short-term production system, the use of non-woven surface defect testing systems "is a new solution provided by non-woven surface defect testing. Detection: For non-woven fabrics itself Thickness and unevenness, structural sparse materials and randomness (front, reverse and middle) of 疵 (front, back and middle), traditional transmission lighting methods easily cause system missions and false positives. Non-woven stain detection The instrument is used as a shadowless field, which is transmitted below the material. The other light source reflects above the material. When the production line starts running, the CCD camera performs synchronous scanning shooting according to the speed signal acquired by the encoder, will collect The image of the image is dynamically distinguished by the image analysis software algorithm. Through the grayscale difference between the 疵 image and the normal product, it is discovered to operate and perform alarm, statistics, classification, record and other operations. Technical parameters: 1, detection object: spin Adhesive, spun, hot tie, chemical bonding, hot air and other non-woven fabric production process, defects and defect detection 2, detection speed: maximum 800 m / min 3, detection width: Adaptable to any width (multi camera Combination) 4, detection accuracy: 0.1mm-0.5mm5, detection content: non-woven surface stain detection (stain, hole, melting point, bright spot, insect, etc.) 6, disposal method: screenshot sound alarm, 自动 automatic classification, automatic record Location, picture automatic storage and retrieval 7, the test summary: the system automatically generates non-woven fabric quality report and defects. System function: 1.100% non-woven surface defects online detection, discovery, can be set according to system setting Light alarm, and the product formation can be automatically tagged (optional) as needed, prompt timely repair, avoid the production of a large defective product; 2. The complete product formation of information statistics, when detecting 疵, system automatically statistics, current 疵Information, area, location, size, etc., each volume of the product has a complete defect image, position distribution, and quantity statistics, can be connected to the printer selection print; 3. High-precision, scheme can detect the set accuracy The hole defects meet the quality requirements for the continuous improvement of customers; 4. Software database management functions can accurately quality statistics, detailed defect record (size and location) and statistics for production process and equipment. State adjustment provides convenient, off-line analysis, for subsequent division and quality management, can effectively guarantee product quality; system main configuration: 1. Adoption of imported high-end brand high-speed industrial camera, board, data cable and Japanese professional optical lens, Ensure that the image acquisition signal is accurate and reduced interference; 2. Adopting industrial control computer system, improve system operation reliability, stability; 3. For industry application characteristics and customer different needs, software can conduct special customization Modification, maximize the actual requirements of the customer; 4. High-brightness LED linear concentrated cold light source, long service life, high detection accuracy, reduce the light source replacement cost; 5. Camera and light source for secondary package fixation, maintenance work is simple, reduce The system has brought more detection errors due to the surrounding environment. FQJ, read full text
