Automated optical inspection equipment for glass core substrates

Abstract

An automated optical inspection device for glass core carriers is suitable for detecting cracks in the glass core layer of a glass core carrier. It includes a stage, a first light source group, a first image capturing device, a control device, and an analysis device. The stage supports the glass core carrier to be inspected. The first light source group is located on a first side of the stage, illuminating the side of the glass core carrier. The first image capturing device is located on a second side of the stage, capturing a first image generated by the first light source group illuminating the glass core carrier from the first side to the second side. The control device controls the opening and closing of the first light source group and the first image capturing device. The analysis device receives the first image and compares it with a built-in first target image to determine whether the first image matches the first target image.
