Description
Technical field
The present invention relates to the end-working and method of processing end of glass plate.
Background technology
In recent years, from from the viewpoint of space-saving, instead of the CRT escopes of conventional popularization, liquid crystal display, etc.
The flat-panel monitors such as gas ions display, organic el display, Field Emission Display are gradually popularized.Also, these FPD
Device is required further slimming.
Particularly, in organic el display, organic EL illuminating, very small (thin) this point of its thickness can be utilized
Come the function of realizing to fold, winding.Thus, be not only convenient for carry, and except used under conventional flat state with
Outward, additionally it is possible to realize the use under curved surface state, it is therefore contemplated that being flexibly applied to various purposes.Therefore, these can
Glass substrate that the electronic equipment of deformation is used, cover glass are also required to further improve flexible.
In order to improve the flexibility of above-mentioned glass plate, glass plate thin-walled property is set to be effective.Here, for example in patent document 1
In propose the glass plate (glass plate of the size is also referred to as glass-film sometimes) that thickness is less than 300 μm, thus, energy
Enough flexibility that the degree for using that can be realized under curved surface state is assigned to glass plate.
On the other hand, the glass plate that is used electronic equipments such as flat-panel monitor, solar cells implement secondary operation,
The various electronic equipment manufacturing relevant treatments such as cleaning.If however, making the glass plate thin-walled that these electronic equipments are used
Change, even if then producing stress slightly to change the situation for also resulting in breakage, when the manufacture relevant treatment of electronic equipment is carried out, deposit
Operating extremely difficult etc problem.On this basis, because thickness is less than 300 μm, particularly less than 200 μm
The rich flexibility of glass plate (glass-film), therefore also it is difficult to asking for positioning etc in the presence of when carrying out various manufacture relevant treatments
Topic.
On above mentioned problem, such as in patent document 2, it is proposed that using a pair of endless belts while carrying on the back sandwich from table
The direction moving glass plate that the edge of glass plate one specifies, and by being configured at the method that the grinding stone of side is ground to end.
On the other hand, for the surface of this glass plate, other components are installed sometimes according to the purposes of glass plate, or be
Face precision very high is directly required so that original state is used.Therefore, if possible, it is desirable to do not make any component with least
The mode that the face that table carries on the back a side abuts carries out the processing such as being ground.
Accordingly, it is considered to for example carry on the back the face (the usually face of downside) of a side by the table of the only supporting glass plate such as platform
Implement the method for grinding under state to end, but in this case, added in the glass plate to conventional thickness
Man-hour can produce the problem that I had never expected.
That is, in this processing (grinding), generally, the mill of the flour milling with shape corresponding with processing mode is used
Stone, in addition, when grinding is carried out using the grinding stone, material, size according to glass plate, grinding method, by the mill of high pressure
Cut the main injection of liquid (water etc.) to grinding stone and the abutting part of the end of glass plate.Now, although the back side of glass plate be (downside
Face) supported by platform etc., but based on it is above-mentioned the reasons why, the surface (face of upside) of glass plate is ground in the state of exposing
Cut processing.
Thus, for example proposing following abrasive machining device in patent document 3, set in the abrasive machining device
There is the cover portion of covering grinding stone, and opening portion is formed in the cover portion, the glass plate to be ground can be made via the opening portion
End abutted with grinding stone.Thus, supply to grinding stone and the mill of the abutting part of the end of glass plate is prevented as far as possible by cover portion
Liquid is cut to be splashed to the face center side of glass plate and be attached to the situation on the surface.

However, glass plate with its thickness diminish and easily because it is external load be deformed so that because being supported with grinding stone
Load when connecing and produce the misgivings of the deformation for bending downwards to increase.Implement grinding in the state of after in so deformation
When, it is impossible to avoid the harmful effect caused to the grinding accuracy of chamfer amount etc..In addition, thickness is smaller, for external load
Intensity it is also smaller, therefore worry cause the breakage (rupture) of glass plate because of the abutting with grinding stone.
In addition, it is necessary to make the end of the glass plate to be processed in the case of by the supporting glass plate such as platform
It is processed in the state of being stretched out from platform etc..If however, in the state of a not part for supporting glass plate implement processing,
Worry that the end of glass plate produces deflection deformation because of its deadweight.Further, since grinding fluid is generally with high pressure conditions supply (spray
Blow), therefore when grinding fluid is born in the end of the glass plate of the state not being supported by completely, worry that the end is rocked (vibration).
Above-mentioned phenomenon more significantly manifests as the thickness of glass plate diminishes.
In addition, the end of glass plate deforms or vibrates because of above-mentioned the reasons why, it may occur that the opening portion of cover portion and glass plate
Gap expand situation.Generally, according to the grinding fluid for being used supply conditions (water, hydraulic pressure etc.), the thickness of glass plate
Size etc. and the gap is set as appropriate size, but when thickness becomes hour, gap correspondingly increases thickness
Become in a small amount, be additionally, since and easily produce above-mentioned deformation, vibration, the misgivings that gap significantly changes (increase) also increase.In the situation
Under, the misgivings of the face center side splashed and be attached to glass plate due to grinding fluid increase, therefore worry to surface accuracy, cleaning
The product qualities such as degree bring harmful effect.In order to tackle because of the increase in the caused gaps such as deformation, though also can in advance by glass
Plate sets smaller with the gap of opening portion, if but do so, rear extended meeting produces because of the flexure of glass plate, rocks and cause glass
The new problem that plate is interfered with opening portion.
The content of the invention
The invention problem to be solved
In view of the foregoing, in this manual, by the invention solves the problems that technical task be, even thickness gauge

Scheme for solving problem
Above-mentioned problem is solved by the end-working of glass plate involved in the present invention.That is, the end-working
Possess supporting glass plate supporting station, for be supported by platform supporting state glass plate end implement regulation processing plus
The Ministry of worker and the cover portion of covering processing department and the opening portion for being provided with making the end of glass plate be abutted with processing department, its
It is characterised by, supporting station has the first support of the central side region of supporting glass plate and the end side of supporting glass plate
Second support in region, the thickness of the second support is set as smaller than the thickness of the first support and can make
Second support passes through the size of the degree of the opening portion of cover portion in the state of the end side region of supporting glass plate.Need
Bright, central side region mentioned here is referred respectively to end side region, in the state of top view glass plate
Center is border with the centre position of end position, and end is leaned on by the region of central side and than centre position than centre position
The region of side.
So, in the present invention, due to supporting station be provided with the central side region of supporting glass plate the first support, with
And the second support of the end side region of supporting glass plate, so even in the case where the thickness of glass plate is small,
It is capable of the end side region of reliably supporting glass plate.In addition, in this case, due to the thickness of the second support being set
It is set to state smaller than the thickness of the first support and that end side region of second support in supporting glass plate can be made
Pass through the size of the opening portion of cover portion down, therefore, it is possible to the state supported by the second support in the end side region of glass plate

By the way that the second support is formed with the first supporting part body like this such that it is able to supporting glass plate will be required
First support of central side region is set to different specifications from the second support of the end side region for requiring supporting glass plate.
Thereby, it is possible to prevent each support specification from determining to obtain too high (over spec), the cost of manufacture of each support can be suppressed
It is relatively low and be accurately processed.In addition, generally, in order to smoothly and reliably be processed the processing in portion, glass plate
End side region is so that the state that given size is stretched out in its end from the second support is supported by the second support.In the situation
Under, sent out during the relation of the thickness for stretching out size and the glass plate stretched out from the second support in the end for studying glass plate
It is existing：From conventional size it is changed into nearest thin-walled size due to the difference of the thickness of glass plate, particularly thickness (so-called
Film size), and the appropriate size (scope) for stretching out size significantly changes.Thus, it is configured to by by the second support
It is enough to be loaded and unloaded relative to the first support, even if in the glass by the identical machining production line multiple species different to thickness
In the case that glass plate is processed, as long as also replacing the second support can just form the bearing state of appropriate glass plate.By
