Description

Technical Field

[0001] The invention relates to the technical field of imaging testing, and in particular to a multi-station fully automatic IRCF imaging testing device. Background Art

[0002] I RCF, also known as infrared cutoff filter, is a filter used to filter infrared bands. When light enters the lens, visible light and infrared light will be refracted and imaged on different target surfaces. Visible light images are in color, and infrared light images are in black and white. Dirt, broken edges, and cracks on IRCF will have a great impact on the image quality of the camera.

[0003] At present, the market uses AOI camera equipment for identification and testing. Since it does not use actual module playback testing, some I RCF will be misjudged as NG, thereby reducing the pass rate. However, if it is only actual module playback testing, some products with damaged edges or cracks cannot be detected.

[0004] Using a single-station I RCF tester or manually using an optical magnifying instrument for testing has low production efficiency and is not suitable for large-scale production in factories. Summary of the invention
