Embodiment
It is described in detail below in conjunction with accompanying drawing embodiment of this disclosure.It should be appreciated that this place is retouched
The embodiment stated is merely to illustrate and explained the disclosure, is not limited to the disclosure.
In the disclosure, in the case where not making opposite explanation, it is real that the noun of locality used such as " upper and lower " typically refers to equipment
" upper and lower " when border is used.
In glass substrate production process, raw material is identical and manufacturing condition identical in the case of, it is sometimes different
The performances such as yields, warpage fraction defective and the percentage of damage of the glass substrate of batch have large change, and the disclosed invention people is unexpectedly
It was found that, the distance of shaping furnace heat sink and the sharp line of overflow brick brick has to the yields of glass substrate, warpage fraction defective and percentage of damage
Considerable influence, concrete reason is as follows：
Glass substrate is with press over system production process, and two blocks of heat sinks of shaping furnace are in the lower section of overflow brick, and glass metal exists
Overflow brick point merge as glass tape and towards ground direction flow and formed solidification glass tape, heat sink to glass tape around
Region is heated, and 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 typically in the lower section both sides of overflow brick brick point and are arranged symmetrically.After current heat sink is installed, staff is general
Both sides heat sink is measured to the distance of overflow brick brick point with Steel Ruler or other survey tools, according to the whole sizing of distance adjustment
Stove, reaches the purpose of Indirect method heat sink.But it is due to that heat sink has certain difference in height (h in Fig. 1) with overflow brick brick point,
Cause staff measurement when can not direct measurement heat sink to overflow brick brick point actual distance, can only estimate, cause pacify
Fill precision not high, heat sink is typically due in follow-up 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
Hot plate is typically carried out to the adjustment process of the sharp distance of overflow brick brick when equipment is installed, and subsequent technique personnel are difficult to find above-mentioned original
Cause, so as to cause glass substrate quality uneven 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 Figure 1-2, the disclosure provides a kind of method for adjusting heat sink centering overflow brick brick point, this method bag first
Include：First marker 4-1 and the second marker 4-2 are respectively placed in the first heat sink 1-1 and the second heat sink 1-2 length sides
To opposite sides；Wherein, the first heat sink 1-1 and the second heat sink 1-2 is located in shaping furnace and perpendicular along short transverse
It is straight to place, the first heat sink 1-1 and the second heat sink 1-2 be parallel to each other along its length and between to form spacing be L's
Overflow brick 2 is provided with above clearance space 100, the first heat sink 1-1 and the second heat sink 1-2, the overflow brick
The sharp line 7 of the brick of bottom brick point 21 is located at the surface of the clearance space 100；By the first marker 4-1 and second line of ink marker
Instrument 4-2 releases first laser face 5 and second laser face 6 respectively in perpendicular, and makes the first laser face 5 and second laser face
6 overlap and both pass through the sharp line 7 of brick of the brick point 21；The first heat sink 1-1 and the second heat sink 1-2 and institute are determined respectively
State first laser face 5 apart from L1 and L2；According to L1 and L2 numerical value, by the first heat sink 1-1 and the second heat sink 1-2 and institute
The absolute value for stating the difference of the distance in first laser face 5 is adjusted to no more than 0.1 millimeter.
By the above method, staff can utilize marker direct measurement heat sink to the distance of lasing area, i.e., straight
The horizontal range of the sharp line of measurement heat sink and brick is connect, measurement accuracy is improved, so that by the first heat sink 1-1 and the second heat sink 1-
2 and the absolute value of difference of distance in the first laser face 5 be adjusted to no more than 0.1 millimeter, improve the non-defective unit of glass substrate
