Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the disclosure.It should be understood that this place is retouched
The specific embodiment stated is only used for describing and explaining the disclosure, is not limited to the disclosure.
In the disclosure, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower " typically refers to equipment reality
" upper and lower " when border uses.
It is sometimes different in the identical situation identical with manufacturing condition of raw material in glass substrate production process
The performances such as yields, warpage fraction defective and the percentage of damage of the glass substrate of batch have large change, the disclosed invention people's will other places
It was found that shaping furnace heat sink has the yields of glass substrate, warpage fraction defective and percentage of damage at a distance from overflow brick brick point line
Larger impact, concrete reason are as follows:
Glass substrate is in press over system production process, and in the lower section of overflow brick, glass metal exists two blocks of heat sinks of shaping furnace
Overflow brick point merge become glass tape and towards ground direction flow and form cured glass tape, heat sink to glass tape around
Region heating forms warm area of the glass tape from molten condition to Solid State Transformation.As shown in Figure 1, in production equipment installation process,
Two blocks of heat sinks generally in the lower section two sides of overflow brick brick point and are arranged symmetrically.After heat sink installation at present, staff is general
Two sides heat sink is measured to the distance of overflow brick brick point, the according to this distance entire sizing of adjustment with Steel Ruler or other measuring tools
Furnace achievees the purpose that Indirect method heat sink.But since heat sink and overflow brick brick point have certain difference in height (h in Fig. 1),
It causes staff that can not directly measure heat sink to the actual distance of overflow brick brick point in measurement, can only estimate, cause to pacify
It is not high to fill precision, heat sink is typically due in subsequent production process and is not waited to overflow brick brick point distance and causes technique adjustment
It can not quantify, bring great inconvenience, and then influence yields, warpage fraction defective and the percentage of damage of glass substrate.Due to dissipating
The adjustment process of hot plate to overflow brick brick point distance is generally carried out when equipment is installed, and subsequent technique personnel are difficult to find above-mentioned original
Cause, to cause glass substrate quality irregular all the time.Therefore, the disclosure provides a kind of adjustment heat sink centering overflow
The method and glass substrate production equipment of brick brick point, to solve the above problems.
As shown in Figs. 1-2, the disclosure provides a kind of method for adjusting heat sink centering overflow brick brick point, this method packet first
It includes: the first ink line meter 4-1 and the second ink line meter 4-2 is respectively placed in the first heat sink 1-1 and the second length side heat sink 1-2
