CCD Camera Visual Inspection System for Texile Industry Defect Dedtection
Product background
The textile industry has penetrated into all aspects of our lives, such as clothing fabrics, luggage accessories, etc. The quality of textile fabrics directly affects the quality of our lives, so many textile manufacturers also attach great importance to quality testing. At present, most enterprises mainly rely on manual detection of fabric defects, marking, recording and classification. Once faced with large orders with short delivery times, manual operations are far from meeting the testing needs. In order to break through the bottleneck faced by the production and development of the textile industry, KEYE TECH has developed a textile optical automatic inspection equipment based on the visual inspection technology accumulated over the years and customer cases, which ensures the product quality of textiles and improves the production efficiency of the entire textile production line.
Inspection principle
The non-woven fabric surface defect detection system sets up a linear CCD camera above the production line.The camera is triggered by an encoder connected to the format driver shaft to obtain the format image information,the camera's resolution/line scan frequency and line width and other performance to determine the image sampling accuracy.The system has high precision and large image data processing capacity. After high-speed processing, the data retains the defect data information and outputs control signals. The computer system records and manages the specific location, size and image information of defects through the database.
Inspection detalis
In the production process of cloth, the highly repetitive and intelligent work such as cloth quality inspection can only be completed by manual inspection. Many inspection workers are often seen behind the modern assembly line to perform this process. While increasing huge labor costs and management costs, it still cannot guarantee a 100% inspection pass rate. The inspection of cloth quality is repetitive labor, prone to errors and inefficient.
The birth of the cloth inspection machine has turned the cloth production line into a fast, real-time, accurate and efficient assembly line. On the assembly line, the color and quantity of all fabrics must be automatically confirmed (hereinafter referred to as "fabric detection"). The automatic identification technology of machine vision is now used to complete the work that was previously done by humans. In large-scale cloth inspection, manual inspection of product quality is inefficient and low in accuracy. Using machine vision inspection methods can greatly improve production efficiency and production automation.
Advantages of CCD vision
| 1)High detection accuracy and fast detection efficiency:CCD visual inspection equipment uses machine control according to the system, with small error and high detection rate. |
| 2)Wide detection range to detect cosmetic defects and dimensional measurements:The multi-station inspection method can accurately measure the outline, specifications, appearance defects, product aspect ratio and other performance parameters of the product to be inspected at one time. |
| 3)Improve product quality and error rates:Vision inspection equipment is based on system control, which can distinguish good products from bad products through automatic inspection technology, and then automatically place them in different parts. |
| 4)Save labor costs and enable high repetitive work:CCD visual inspection can work stably for a long time, it is difficult for human eyes to observe the same object for a long time, and machine vision can perform measurement, analysis and recognition tasks for a long time. And it can continue to work, with low requirements for the natural environment of the application, in addition to saving product costs, it also greatly improves productivity. |
| 5)Improve company competitiveness and employee safety factor:Non-contact detection, which does not cause any damage to observers and observers, improves the reliability of the system. Machine vision technology guarantees the ultimate human-machine interaction technology, which ensures a better and safer workplace. |
