Description

Technical Field

[0001] The present disclosure relates to the technical field of glass substrate production and manufacturing, and in particular to a supporting structure and a shaping furnace. Background Art

[0002] During the production of optoelectronic display glass, glass substrates can experience uneven light transmittance due to large local variations in thickness. A sudden decrease in thickness can cause the glass to scatter light, resulting in dark bands. Conversely, a sudden increase in thickness can cause the glass to focus light, resulting in bright bands. To address this issue, the forming process installs alumina ceramic platinum heating ducts in the A3 area above the cooling ducts in the shaping furnace to correct the thickness variations and eliminate the bright and dark band problem on the glass substrate.

[0003] Currently, there is no standard support structure on the production line to support and fix the heating air duct. The positioning of the heating air duct is inaccurate and can easily change due to accidental touch. This will cause the quality of the bright and dark bands of the glass to be excessive, affecting the quality of the glass substrate and the production yield.
