Now non-woven fabrics in the production process will produce a lot of various defects stain, nodes, etc., seriously affecting the quality of products and corporate image. No Xisaimofei Science and Technology Co., Ltd. In response to this phenomenon, research production of precision measurement and control spectrum of non-woven surface defect online inspection system is mainly based on advanced machine vision technology, combined with the characteristics of non-woven fabrics and sparse texture, the use of positive exposure, negative projection imaging modalities combined, enables online high-speed, accurate surface defect detection; binding site process online alarm, automatic reports, statistics and product classification disposal for the production of information technology and product quality and so provide an effective solution.
Control spectra of the nonwoven fabric surface defects fine line detection system works:
Aiming at the randomness of the non-woven fabric itself, the structural sparse, the randomness (front, back and middle) of the defect distribution (the front, back and middle) of the nonwoven fabric is easy to cause the system's misproductive inspection and false positives. Control spectra fine line detection system using a nonwoven fabric flaw shadowless bright field detecting ambient composition, i.e., a material that transmits light below, an additional light source reflector above the material in the production line starts running, the CCD camera is acquired in accordance with the encoder scanning velocity imaging synchronizing signal, the dynamic image is acquired by dividing the fine spectral Control for image analysis software algorithm, with the normal grayscale difference image defect products, to discover defects and make an alarm, statistics, classification, records and other operations.
Control spectra of the nonwoven fabric surface defects fine line detection system mainly performance
1. Typical defects: stains, node, mosquitoes, foreign matter, oil, wrinkles and fiber
2. Detection Width: any width (the increase to meet different combinations of camera width);
3. Detection speed: Maximum 2000m / min;
4. Detection Accuracy: maximum detection accuracy of 1um (increasing the number of cameras to improve the detection accuracy)
Control spectra of the nonwoven fabric surface defects fine line detection system Scope:
For determining fracture textile material, glass fiber, composite, nonwoven fabric, felt paper, nonwoven material, geotextile material, waterproof material, rope, plastic bags, rubber, plastics and other strength and elongation at break. This machine is a multi-function type other functions can be customized according to customer requirements: monofilament strength, elongation set, constant load, position shift, tearing, peeling, bursting, bending, the seam slippage at the tensile test.
Control spectra of the nonwoven fabric surface defects fine line detection system specifications and functions:
Main configuration: High-speed high-performance industrial computer, special purpose machine vision image processing software, high-resolution line scan camera, led long-life light source independent intellectual property rights, etc.
Key Features: You can configure any number (recommended configuration 3-4) industrial cameras, in order to achieve the required resolution, the maximum test speed of up to 500m / min;
Main features: front finished, the finished surface of various defect detection, to record the position (roll length direction and the width direction), automatically determine the type of defect, the defect is automatically saved image information, the system automatically generates a report and the web quality defect distribution graph.
Typical defects such as: particles, black spots, leakage woven, microporous, nodes, drawing, folding, fibers, stain, gum, oil / stain, oligomer powder, foreign bodies (insects / hair, etc.) and breakage . (0.01mm precise accuracy at high speed, adjustable speed)
