AI Technical Summary
In existing technologies, the heating range of a single nozzle is limited, making it difficult to cover the entire edge of the overflow port. This results in uneven temperature distribution, which can easily lead to localized solidification and stress marks, reducing the yield of glass substrates.
The device employs a dual-nozzle design, heating the edge of the overflow port through two nozzles. The nozzle spacing can be adjusted using an adjustment component to accommodate overflow port edges of varying widths, resulting in a wider heating range and ensuring temperature uniformity. Furthermore, the easy-to-replace nozzles facilitate replacement and maintenance.
It enables large-area heating of the overflow port edge, ensuring temperature uniformity, improving the yield of glass substrates, and facilitating the maintenance and replacement of the gun head.
