Description
Technical field
The invention relates to it is a kind of for brittle material substrate, especially to the glass substrate comprising strengthened glass into
The break bar and scoring device of row delineation.
Background technique
Strengthened glass, with by the chemically processing of the ion exchange in manufacturing step, and in the superficial layer of glass plate
(depth is 5 μm~50 μm or so from surface) forms the remaining compressive stress layers of compression stress, and remains in inside of glass plate
Glass manufactured by the mode of stretching stress.
The feature of strengthened glass has and is difficult to the property ruptured for external force because of the influence of compressive stress layers, on the contrary,
Once generating cracking in glass pane surface and to inside of glass plate existing for residual stretching stress, then make in having instead instantly
Cracking becomes easy the property for deepening to be impregnated with.
In general, in the method for break bar disjunction glass plate, be by first with break bar (also known as scribe wheel) in glass plate
Surface formed finite depth score line (rib trace) the step of and thereafter by the back side from glass plate along score line with brisement bar
Or brisement roller is pressed and constitutes (referring to patent document 1 and patent document 2) the step of brisement.
In in the method for break bar delineation glass plate, there are " circumscribed " and " inscribe ", and circumscribed and inscribe delineation side
Method can be selectively used separately according to type or thickness, the purposes of glass plate (referring to patent document 2).
Patent document 1: No. 3074143 bulletins of Japanese Patent Publication No.
Patent document 2: Japanese Unexamined Patent Publication 2009-208237 bulletin
The former " circumscribed " is as shown in Figure 7 A the method for delineation performed in the following way: by the bottom of break bar K
To drop to compared in the state of the surface glass plate M (above) slightly lower section, it is set in the outer fix of the unilateral end of glass plate M
(delineation starting position).Then, it moves horizontally break bar K from setting position, is collided with the end glass plate M and form initial trace,
Further on one side pressed with set delineation, while move horizontally.
In above-mentioned circumscribed means (method), the sword front end of break bar K is good in being carved into of the end glass plate M (intrusion), energy
Enough initial traces easy to form, and since machined score line is to the end for reaching glass plate M, in following step
In brisement can easily and accurately carry out.
However, in the situation of strengthening glass sheets, for invading sword front end due to the influence of the residual stress of its superficial layer
Glass plate ends need stronger pressing load, especially as shown in Figure 8 by the base of end face R progress chamfered
Plate, since sword front end is easy sliding, it is therefore necessary to set stronger pressing load, become the impact in the collision of base ends
Greatly.Therefore, it has sometimes and generates shortcoming in the end of strengthening glass sheets, be broken from glass plate ends and irregular cracking is leading
Situations such as.In addition, also break bar side because with strengthening glass sheets end have it is stronger collision due to be easy to produce sword front end abrasion or
Sword damage etc., so that service life shortens.
" inscribe " of the latter is as shown in Figure 7 B the method for delineation performed in the following way: at the end from glass plate M
(delineation starting position) keeps break bar K lowered from above and compresses with set delineation to be connected to glass on the inside of genesis 2mm~10mm or so
Glass plate M moves horizontally break bar K while pressing.
In above-mentioned inscribe means, as break bar K do not have with the end glass plate M collision as situation, no
It has the case where the end glass plate M generates shortcoming.In addition, the consume about sword front end can also be obtained compared to circumscribed situation
It must inhibit.
However, in the situation of strengthening glass sheets, when making sword front end press down and be connected to glass pane surface, sword front end
Intrusion toward glass pane surface layer is bad in the extreme, therefore, has the feelings for becoming difficult delineation processing due to generation because sliding sometimes
Shape.In addition, there is such as such as the following bad situation sometimes: if being loaded and being carried out with stronger pressing to invade sword front end
Delineation then causes disposably to be broken and complete disjunction because of the influence of the residual stretching stress of strengthened glass intralamellar part, if by sword
The toe angle of front end is set as smaller, then makes the antecedent circumstance in front of the irregular direction of travel for being cracked and resulting from sword front end
It is easy to produce.
As so, the delineation of strengthening glass sheets is processed, with the quarter to existing known used sodium lime glass plate etc.
It is different to draw processing, even by " circumscribed ", even or by " inscribe ", being difficult to form score line well.The tendency,
The biggish glass plate of thicker and residual stress or the cover glass as protected liquid crystal surfactant in the compressive stress layers of glass pane surface
The curvilinear situation delineated to 4 corners significantly more occurs Deng as.
It can be seen that above-mentioned existing break bar and scoring device are in structure and use, it is clear that there are still have it is inconvenient with it is scarce
It falls into, and needs to be further improved.To solve the above problems, relevant manufactures there's no one who doesn't or isn't painstakingly are sought to solve
Road, but have no that applicable design is developed completion always for a long time, and common product is able to solve without appropriate structure
The above problem, this is clearly the problem of correlation dealer is suddenly to be solved.
