Principle and Function of Defect Detection System for Melt Blown Non-woven Fabric

Detection method of precision spectrum measurement and control melt blown non-woven fabric defect detection system - at present, the detection of non-woven fabric defects is mainly solved by manual detection. However, this method has a slow detection and processing speed, and will cause relatively high labor intensity to workers. At the same time, the final detection effect will be greatly affected by the work experience of inspectors Due to the influence of many factors such as familiarity with process operation, the test results are not reliable. With the continuous development of textile industry and the continuous expansion of production scale, it is more and more urgent to develop a non-woven fabric defect on-line detection system to realize stable, fast and accurate detection.

The precision spectrum measurement and control melt blown non-woven fabric defect detection system integrates the current leading machine image vision acquisition technology, photoelectric identification technology, as well as the supporting powerful and complete computer machine vision image software and hardware combination suitable for the production of domestic non-woven fabric products, so as to accurately, accurately and quickly detect the surface defects (defects) of on-line non-woven fabrics at a high speed High resolution industrial camera image display defects are intuitive and super clear. Abandon the "original" online quality inspection relying on cumbersome and low-quality manual naked eyes. Because machine vision inspection adopts unified standards, it is not affected by artificial fatigue / emotion / misjudgment and other factors, which can greatly improve the production efficiency and yield, reduce the labor cost and return rework cost, and realize safety, speed, convenience, quality and quantity.

Detection principle of precision spectrum measurement and control melt blown non-woven fabric defect detection system:

In view of the uneven thickness, sparse and uneven structure of non-woven fabric and the randomness of defect distribution (front, back and middle of non-woven fabric), the traditional transmission lighting method is easy to cause systematic missed detection and false alarm. The non-woven stain detector adopts a shadowless bright field to form the detection environment, that is, one light source transmits below the material and the other light source reflects above the material. When the production line starts running, the CCD camera scans and shoots synchronously according to the speed signal collected by the encoder, and the collected image is dynamically segmented through the image analysis software algorithm, Through the gray-scale difference between the defect image and the normal product, we can find the defect and carry out alarm, statistics, classification, recording and other operations.

Functions of precision spectrum measurement and control melt blown non-woven fabric defect detection system:

1. Real time display of defect location distribution map;

2. Real time defect image specific information display;

3. Automatically generate the product batch number, and manually modify the product batch number during production;

4. Establish a complete historical database query according to the product batch number;

5. The history record automatically generates the defect position distribution map in reverse order corresponding to the batch number, which is convenient for later volume division;

6. Statistical generation and printing of information report;

7. Real time capture and display of defect pictures;

8. Long time and large capacity history storage;

9. Remote technical services;
