OVERFLOW BRICK AND GROOVE BOTTOM CURVE DESIGN OPTIMIZATION METHOD THEREFOR

Document Type and Number:

WIPO Patent Application WO/2021/057800

Kind Code:

A1

Abstract:

The present invention relates to the field of glass substrate manufacturing, and disclosed are an overflow brick and a groove bottom curve design optimization method therefor. The method comprises: S1, obtaining a standard lead-out amount of an overflow brick according to design parameters of the overflow brick; S2, obtaining an initial overflow brick groove bottom curve according to the standard lead-out amount of the overflow brick; S3, performing rectilinear correction on the initial overflow brick groove bottom curve according to the length of an overflow brick shunting block to obtain an overflow brick groove bottom curve; S4, obtaining, according to the overflow brick groove bottom curve and the design parameters of the overflow brick, a thickness range of a formed glass substrate by means of overflow simulation; and S5, when the thickness range of the formed glass substrate is smaller than or equal to a preset threshold, using the overflow brick groove bottom curve and the design parameters of the overflow brick to perform overflow brick machining, and when the thickness range of the formed glass substrate is greater than the preset threshold, adjusting the design parameters of the overflow brick and repeating steps S1-S4. The problem of fluctuation of the forming thickness of a glass substrate is solved, and the production allowance is increased in design, so that the forming thickness of the glass substrate can satisfy the requirements.
