How is the detection efficiency of the non-woven online defect detection equipment

As users have increasingly strict requirements on the quality of non-woven fabrics, more and more manufacturers have begun to pay attention to the surface quality of non-woven fabrics. Black spots, mosquitoes, melting points, holes, wrinkles, hanging silk and other defects are non-woven fabrics. Major defects on the surface, even minor defects will affect the quality of the product. In addition, online testing equipment is also a standard for customers to purchase products.

At present, traditional production enterprises rely on human eyes for defect detection. However, due to the high cost of manual inspection, fatigue and the inability of human eyes to detect on high-speed production lines, traditional human eye inspection cannot meet high-quality production processes. Requirements. Okplazas. com's non-woven fabric surface defect online detection system can perform high-speed and accurate online defect detection, and combine with on-site process online alarm, report statistics and product classification processing to provide effective solutions for companies to ensure product quality.

Detection principle:

In view of the uneven thickness of the non-woven fabric, the sparse and uneven structure of the material characteristics, and the randomness of the distribution of defects (the front, back and middle of the non-woven fabric), the traditional transmission lighting method is likely to cause system missed detection and false alarms. The non-woven stain detector uses a shadowless bright field to form the detection environment, that is, one light source transmits under the material, and the other light source reflects above the material. When the production line starts to run, the CCD camera synchronizes according to the speed signal collected by the encoder Scanning and shooting, the collected images are dynamically segmented through image analysis software algorithms, and the grayscale differences between the flawed image and the normal product are used to find the flaws and perform alarm, statistics, classification, and recording operations.

technical parameter:

1. Inspection object: detection of fabric surface defects and defects in the production process of spunbond, spunlace, hot-rolling, chemical bonding, hot air and other non-woven fabrics

2. Detection speed: up to 800 m/min

3. Detection width: can adapt to any width (multiple cameras can be combined)

4. Detection accuracy: 0.1mm-0.5mm

5. Detection content: detection of stains on the surface of non-woven fabrics (stains, holes, melting points, bright spots, insects, etc.)

6. Disposal methods: screenshots, sound and light alarm, automatic classification of defects, automatic recording location, automatic storage and retrieval of pictures

7. Inspection summary: The system automatically generates non-woven web quality reports and defect distribution charts.

Software function:

1. Simple operation interface, convenient for workers to operate.

2. Support the setting function of different customers and different quality standards.

3. Defects of the same customer are classified according to requirements.

4. Synchronize with on-site equipment production, display defect location information and image information in real time.

5. The batch number can be generated in real time according to customer requirements; the batch number can be modified during the production process.

6. When the production of each batch number is finished, the quality report of the batch number product is automatically generated; automatic printing function is supported.

7. The product quality of all batch numbers can be called back at any time to analyze product quality information.

8. The history record supports long-term storage, and can be deleted regularly and quantitatively to automatically delete the history record, saving computer space and displaying the defect location distribution map;

9. Gold medal technical service function to solve operational difficulties at any time.
