Visual alignment of OGS glass

     Because the MARK position of the product is coated with oil ink, consider how to see the MARK mark through the ink when registering.

    1 Use a high-brightness strip light source; the purpose is to prevent the ink area from reflecting, and let the CCD pass through the ink to see the MARK point clearly.

    2 High depth of field telecentric lens using Dehong Technology; the purpose is to make the product clear at a certain height

    3 If necessary, add additional light sources to make MARK more visible
