Title:
GLASS PLATE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2017/104354
Kind Code:
A1
Abstract:
A glass plate manufacturing method 1 is provided with: a machining step S2 of machining a glass plate; a cleaning step S3 of cleaning the glass plate machined in the machining step S2; and an inspection step S4 of detecting defects in the glass plate cleaned in the cleaning step S3. The inspection step S4 includes: a defect coordinate identifying step S4a of identifying defect coordinates; and a defect detail identifying step S4b of identifying the details of the defect at the coordinates identified in the defect coordinate identifying step S4a. The number of lines for implementing the defect detail identifying step S4b is greater than the number of lines for implementing the defect coordinate identifying step S4a, and the glass plates that have passed through the line for implementing the defect coordinate identifying step S4a are allocated to the lines for implementing the defect detail identifying step S4b.
