CCD Camera Film Surface Defect Online Visual Inspection System

Technical parameters

Inspection principle

The output of the vision system is not the image and video signal, but the detection result (such as defect, size, etc.) after calculation and processing. Usually, machine vision inspection is to use machines instead of naked eyes for measurement and judgment. First, a CCD camera is used to convert the captured object into an image signal, which is sent to a dedicated image processing system, and converted into a digital signal according to pixel distribution, brightness, color and other information.

Inspection details

Due to the influence of the production process and the on-site environment, it is easy to cause black spots, crystal spots, pockmarks, holes, lines, folds, mosquitoes, scratches and other defects on the surface of the film, which not only affect the appearance of serious film products, but also bring great harm to the enterprise. to economic loss. Only by detecting the defects on the surface of the film in time during the production process can the defects be eliminated from the root of the production.

Compared with the traditional manual naked eye detection, the CCD-based thin film surface defect detection system has the advantages of fast, reliable and accurate, real-time online detection, automatic alarm and display of specific information of the current defect, so as to deal with it in time.

Features of system

Rich software functions, the system can partition the detection area by column; accurate defect coordinate distribution map, showing the specific images of multiple defects in the current period and before and after; real-time defect information display, recording the type, area (diameter), horizontal and vertical position of the current defect and other information; product basic information module, which records product batch number, model, specification, shift number, operator and other information (can be modified by yourself); real-time detection of meters and alarm information display; Classification.

Automatic alarm for periodic and continuous defects, you can set the alarm density by yourself; automatically generate defect record reports for each roll of products, and users can call information to print at any time; automatically change rolls and automatically print quality reports; can be linked with the user's production line to provide remote Technical services; software functions and interfaces can be customized and developed according to user requirements.
