AI Technical Summary
Existing ink breakage detection technology for inkjet printers suffers from insufficient real-time performance, low accuracy, and inability to accurately locate individual nozzles, resulting in high product scrap rates and low production efficiency.
By establishing a mapping relationship between pixel coordinates and physical coordinates, the camera's frame rate is dynamically adjusted. Adaptive filtering and color space conversion technologies are used to achieve real-time image preprocessing and ink breakage identification, accurately locate faulty nozzles, and output audible and visual alarm signals and linkage control commands according to the severity.
It enables real-time ink interruption detection during the inkjet printing process, providing rapid response and accurate positioning of individual nozzles, thereby reducing product scrap rates and improving detection accuracy and production efficiency.
