Apparatus and methods for determining surface compliance for a glass surface

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.

1. A method for determining surface quality for a glass surface, the method comprising:
depositing a pattern of drops over a first portion and a second portion of the glass surface using a drop dispensing apparatus after the first portion and the second portion of the glass surface undergo a cleaning operation, where adjacent drops have a predetermined deposit size and a predetermined deposit spacing; generating a first output of drop information for the pattern of drops on the first portion of the glass surface and a second output of drop information for the pattern of drops on the second portion of the glass surface using a vision apparatus; determining an out-of-parameter condition using a controller analyzing the first output of drop information for the pattern of drops on the first portion of the glass surface and the second output of drop information for the pattern of drops on the second portion of the glass surface caused by surface tension variations across the first portion and the second portion of the glass surface resulting from the cleaning operation; and providing an indication of the out-of-parameter condition using the controller, for determining the surface quality for the glass surface.
