Visual flash tester is a high-precision optical measuring instrument mainly used for rapid detection of parameters such as size, shape, and positional tolerances of workpieces. It adopts optical imaging technology and image processing algorithms, and avoids damage to the workpiece caused by traditional contact measurement through non-contact measurement. The core advantage of the visual flash tester lies in its fast and accurate measurement ability. Multiple dimensional data can be obtained simultaneously in a single measurement, which is much more efficient than traditional tools such as calipers and micrometers. The measurement accuracy can reach the micrometer level and is suitable for batch inspection of precision parts.
Visual flicker testers are widely used in multiple industries, especially in the quality control process of automotive manufacturing, 3C electronics, and other fields, playing an important role. It is easy to operate, with automatic focusing and intelligent contour recognition, reducing human operation errors and improving detection efficiency and product quality. In addition, the visual flash tester is also suitable for batch measurement of small workpieces, supporting batch measurement of 1000 workpieces, and has built-in software to quickly generate inspection reports.
The visual flicker tester captures two-dimensional or three-dimensional images of the object being measured through a high-resolution camera, and combines them with algorithms for automated analysis. The core process includes:
Optical imaging: Using a dual telecentric lens with a large field of view, large depth of field, high numerical aperture, and low distortion, the image contour of the measured object is reduced several times to tens of times, and transmitted to a high-resolution camera for digital processing.
Image processing: The backend drawing and measurement software quickly captures the product contour according to preset programming instructions, compares it with the ruler formed by the camera's tiny pixels, and calculates the product size and tolerance.
Data output: Automatically generate data tables after measurement is completed, support SPC statistical report generation, facilitate production process statistics and analysis.
No need for professional operation, workpieces can be placed freely, and the instrument automatically recognizes, matches templates, and measures with one click, greatly reducing training costs. Support CAD file import, automatically matching measurements without programming, simplifying the operation process. Avoiding potential damage to precision workpieces from traditional contact measuring tools such as calipers and micrometers, it is suitable for detecting surface sensitive objects.
