Black Spot Detection Equipment On The Film Production Process

Technical parameters

Inspection background

The surface flaws of industrial products seriously affect the quality of the product itself. How to avoid surface flaws and carry out quality control has always been the biggest problem facing manufacturers. The traditional manual inspection is not only expensive, the inspectors are prone to fatigue, and defects are easily missed. However, it has been difficult to adapt to the high-speed production system. It is necessary to know that the application of intelligent visual inspection in industry provides a new solution for surface defect detection.

Inspection principle

The film surface inspection system is mainly used to detect black spots, crystal points, scratches, holes, lines, wrinkles, mosquitoes and other defects on the surface of the film during the production process.

With the aid of an imaging system for film surface defect detection consisting of an industrial CCD camera and a high-brightness LED linear concentrating light source, it can timely and accurately reflect specific information such as the picture, shape, size and position of the defect, and provide quality control and product rating. While providing accurate data, it effectively saves production costs and improves product quality.

Inspection details

For thin film materials with high light transmittance, the system adopts the transmission lighting detection method for detection, that is, the light source is below the film, and the camera is above the film for image shooting (for opaque materials, the reflective lighting method is used, that is, the light source on the same side of the surface to be inspected as the camera).

When the production line is running, the system collects the real-time running status information of the production line through the encoder and starts to detect. The system uses the image collected by the camera to process the defect through the precision measurement and control image analysis software. Because the defect and the image of the normal product are on the gray scale There are obvious differences, so that the system can find the flaws, and determine the size, location, type and other information of the flaws through further calculation and analysis.
