Overflow brick and groove bottom curve design optimization method therefor

A groove bottom curve design optimization method for an overflow brick, comprising:

• S1:
• obtaining a standard output of the overflow brick based on design parameters of the overflow brick;
• S2:
• obtaining an initial groove bottom curve of the overflow brick based on the design parameters of the overflow brick and the standard output of the overflow brick;
• S3:
• obtaining a groove bottom curve of the overflow brick through straight line correction of the initial groove bottom curve of the overflow brick based on a length of a splitting block of the overflow brick;
• S4:
• obtaining an extreme thickness difference of a formed glass substrate through overflow simulation based on the groove bottom curve of the overflow brick and the design parameters of the overflow brick;
• and
• S5:
• when the extreme thickness difference of the formed glass substrate is smaller than or equal to a preset threshold, processing the overflow brick based on the groove bottom curve of the overflow brick and the design parameters of the overflow brick;
• and when the extreme thickness difference of the formed glass substrate is greater than the preset threshold, adjusting the design parameters of the overflow brick and repeating steps S1 to S4.
