    摘要: Disclosed is an apparatus for characterizing attributes of a moving glass sheet comprising complementary mechanical material handling technologies that progressively stabilize, position, capture, flatten, and release the lower portion of glass sheets traveling past the apparatus while posing minimal constraint on the top section of the sheet. The apparatus includes a pressure-vacuum (PV)-type device comprising distinct regions such that the glass sheets experience a non-contact but gradual increase in constraining force until the point where measurements can be performed, then a gradual decrease in constraining force until the glass sheets are released from the inspection station. This graduated force technique is applied along the direction of travel of the sheets and may also be applied vertically upwards along the height of the sheet to restrict the motion of the sheet without constraining it at pinch points near the conveyor.

    摘要: A thickness of at least one preselected portion of a substrate, such as glass substrate for example, is controlled. A laser beam is directed to the at least one preselected portion of the substrate in a viscous state, thereby increasing a temperature and reducing a viscosity of the at least one preselected portion of the substrate in a viscous state sufficiently to cause the at least one preselected portion of the glass substrate to attain a desired thickness. The laser beam after it is generated can be directed to a reflecting surface from which the laser beam is reflected to the at least one preselected portion of the substrate in the viscous state. The substrate can comprise a glass ribbon produced in a downdraw glass forming process for example, and the laser beam can be directed onto a plurality of preselected portions of the glass ribbon.

    摘要: A method for determining surface quality for a glass surface is provided. The method includes depositing a pattern of drops over the glass surface using a drop dispensing apparatus. Adjacent drops have a predetermined deposit size and a predetermined deposit spacing. Drop information for the pattern of drops is generated using a vision apparatus. An out-of-parameter condition is detected by analyzing the drop information and an indication of the out-of-parameter condition is provided.

    摘要: A method for inspecting a transparent substrate provides an index-matching fluid between an index-matched optical coupler and a surface of the transparent substrate. The method repeats, at two or more positions along the surface of the transparent substrate, steps of illuminating an inspection volume within the transparent substrate by directing a ribbon of light through the optical coupler and into the transparent substrate and detecting scattered light from the inspection volume at a detector that is optically conjugate with the inspection volume.
