Description

本発明は板ガラスの加工装置に関し、特に、薄板ガラスに孔及び／又は抉りを設けることができる、薄板ガラスの加工装置に関する。   The present invention relates to a processing apparatus for flat glass, and more particularly to a processing apparatus for thin glass, in which holes and / or creases can be provided in the thin glass.

電子機器を始め、多くの機器はディスプレーとしての表示窓を有しているが、昨今の機器の小型化によるスペースの都合上、表示窓の一部にスイッチ類又はスピーカー等を配置する必要が生じ、表示窓に長孔又は抉り部等が設けられることが多い。これらの孔や抉りの位置及び寸法は、特に製品自体が小型である場合、寸法誤差が±0.1mm以下という、高い精度が要求される。
特に最近は、これらの機器のデザインが多様化し複雑化するのに合わせて、より高い精度が要求される傾向にある。このような孔や抉りを有する表示窓の製造には、通常、軽量である上加工が容易なポリカーボネート樹脂が主として使用されている。 Many devices, including electronic devices, have a display window as a display, but due to space limitations due to the recent miniaturization of devices, it is necessary to place switches or speakers in part of the display window. In many cases, the display window is provided with a long hole or a bent portion. The positions and dimensions of these holes and punches are required to be highly accurate with a dimensional error of ± 0.1 mm or less, particularly when the product itself is small.
In particular, recently, as the design of these devices is diversified and complicated, there is a tendency for higher accuracy to be required. For manufacturing display windows having such holes and ridges, polycarbonate resins that are lightweight and easy to process are mainly used.

特に、最近の機器にはタッチパネルが導入される傾向がある。しかしながら、タッチパネルは頻繁に指で触れられたり強く押されたりするので、ポリカーボネート樹脂では、傷や歪みが生ずることが懸念される。そこで、厚さ0.5〜1.1mmの薄板ガラスが表示窓に使用されることが多くなっているものの、薄板ガラスの場合には、小型又は複雑な形状の抉りや孔を設ける加工が困難であるという欠点があった。   In particular, there is a tendency for touch panels to be introduced in recent devices. However, since the touch panel is frequently touched with a finger or pressed strongly, there is a concern that the polycarbonate resin may be scratched or distorted. Therefore, although thin glass with a thickness of 0.5 to 1.1 mm is often used for display windows, in the case of thin glass, it is difficult to process a small or complicated shape of a ring or a hole. There were drawbacks.

従来、板ガラスに長方形や楕円形等の、円形以外の孔又は抉りを設ける加工を行う場合には、孔又は抉りの形状に沿って、ドリルを用いて一列に並べた多数の小孔を開け、該小孔に囲まれた部分を打ち抜いた後、切断面を研磨して整える方法が採用されていた。
しかしながら、この方法は加工に長時間を要し、効率的ではないという問題があった。 Conventionally, when performing processing to provide a hole other than a circle, such as a rectangle or an ellipse, or a hole in a plate glass, a number of small holes arranged in a line using a drill are made along the shape of the hole or hole, After punching out the part surrounded by the small holes, a method of polishing and preparing the cut surface has been adopted.
However, this method has a problem that it takes a long time for processing and is not efficient.

上記の欠点を改良する、板ガラスに抉り部を設ける場合の切断方法として、素板ガラスの抉り部のスクライブ線と抉り部以外の部分のスクライブ線との間に隙間を設け、抉り部のスクライブ線を素板ガラスの周縁部付近まで延長する異形切断方法が開示されている（特許文献１）。   As a cutting method in the case of providing a bent portion on the plate glass to improve the above disadvantages, a gap is provided between the scribe line of the bent portion of the base plate glass and the scribe line of the portion other than the bent portion, and the scribe line of the bent portion is provided. A modified cutting method that extends to the vicinity of the peripheral edge of the base glass has been disclosed (Patent Document 1).

しかしながらこの方法では、スクライブ線が不連続であり、該不連続部分は亀裂の波及効果によって切断される（特許文献１、５頁３２‐３３行参照）ので、薄板ガラスの場合は破損する恐れがある。また、仮に破損を回避することができたとしても、スクライブ線がなかった部分については、寸法に狂いが生じる恐れがある。このような寸法の狂いは、抉りが大きい場合にはそれほどの影響はないが、抉りが小さい場合には相対的に大きな寸法の狂いとなる。   However, in this method, the scribe line is discontinuous, and the discontinuous portion is cut by the ripple effect of the crack (see Patent Document 1, page 5, lines 32-33). is there. Moreover, even if damage can be avoided, there is a possibility that the dimension of the portion where there is no scribe line may be out of order. Such a dimensional deviation is not so much affected when the sag is large, but becomes relatively large when the sag is small.

Further, the shape of the ring and the hole is not limited to a shape consisting of only a straight line or a curve such as a rectangle, a circle or an ellipse, but may be a shape formed by combining a straight line and a curve.
Moreover, it is preferable to use soda-lime glass which is inexpensive and excellent in workability as the thin glass.
Hereinafter, the present invention will be described in detail based on examples.

本発明の薄板ガラスの加工装置は、少なくとも、サンドブラスト装置及び研磨装置からなる。図１は、本発明における、サンドブラスト工程で使用される装置における１つのサンドブラスト手段近辺の概略図であり、図２はこの一組の装置を複数有する装置の概念図を表す。尚、本図の場合には、マスキングプレートは、１枚で３組分を覆うようになっている。前記サンドブラスト装置は、マスキングプレートと整合するように、薄板ガラス６を固定する手段を有するテーブル１、該テーブル１に予め定められた位置に上下に可動に、例えば蝶番を介して固定された前記薄板ガラスをマスキングするマスキングプレート２、及びサンドブラスト手段３を有している。テーブル１に固定された薄板ガラス６は、切り欠き２１を有するマスキングプレートによりマスキングされ、次いで、前記切り欠き２１によって薄板ガラスが露出した部分を、サンドブラスト手段３により切削する。本装置は、図２に示すように、複数の薄板ガラスを同時に処理することができるように構成されることが好ましい。   The thin glass processing apparatus of the present invention comprises at least a sandblasting apparatus and a polishing apparatus. FIG. 1 is a schematic view of the vicinity of one sandblasting means in an apparatus used in the sandblasting process according to the present invention, and FIG. 2 is a conceptual diagram of an apparatus having a plurality of this set of apparatuses. In the case of this figure, one masking plate covers three sets. The sandblasting device includes a table 1 having means for fixing the thin glass 6 so as to be aligned with the masking plate, and the thin plate fixed to the table 1 at a predetermined position in a vertically movable manner, for example, via a hinge. A masking plate 2 for masking glass and a sandblasting means 3 are provided. The thin glass 6 fixed to the table 1 is masked by a masking plate having a notch 21, and then the portion where the thin glass is exposed by the notch 21 is cut by the sandblasting means 3. As shown in FIG. 2, this apparatus is preferably configured so that a plurality of thin glass sheets can be processed simultaneously.

図３は、テーブル１に設けられる、薄板ガラスを予め定められた位置に位置決めする手段の１例である。この場合には、矢印の方向に可動なガイド１３を用いて薄板ガラス６を移動させ、テーブル上に固定されたＬ字型固定具１２に薄板ガラス６を固定して位置決めする。   FIG. 3 shows an example of means for positioning the thin glass plate provided at the table 1 at a predetermined position. In this case, the thin glass 6 is moved using the guide 13 movable in the direction of the arrow, and the thin glass 6 is fixed and positioned on the L-shaped fixture 12 fixed on the table.

また、位置決めされた薄板ガラス６をテーブルに固定する手段としては、薄板ガラス６を傷つけず該薄板ガラス６の着脱を容易に行うことができる、真空吸着手段（図示せず）が好ましい。   Moreover, as means for fixing the positioned thin glass 6 to the table, vacuum suction means (not shown) that can easily attach and detach the thin glass 6 without damaging the thin glass 6 is preferable.

前記テーブル１に固定された前記薄板ガラス６にマスキングするマスキングプレート２としては、サンドブラストによる破損を防ぐ観点から、通常金属製のものを使用することが好ましい。また、マスキングプレート２の薄板ガラス６と接触する面は、薄板ガラス６を保護するために、樹脂フィルム等で被覆されている必要がある。このマスキングプレートは、例えばガイドピン１５等により予め定位置に上下可動に配置されており、該マスキングプレートと整合するように位置決めされ、吸引固定された前記薄板ガラス６の上面を覆うことができる。また加工時には、例えばマスキングプレートを保持する保持枠１１等の公知の手段によって、加工される前記薄板ガラス６の上面に、上部から圧接されることが好ましい。   As the masking plate 2 for masking the thin glass 6 fixed to the table 1, it is preferable to use a metal plate usually from the viewpoint of preventing breakage due to sandblasting. The surface of the masking plate 2 that contacts the thin glass 6 needs to be covered with a resin film or the like in order to protect the thin glass 6. The masking plate is disposed in advance in a fixed position in advance by a guide pin 15 or the like, for example, and can cover the upper surface of the thin glass 6 that is positioned so as to be aligned with the masking plate and fixed by suction. Further, at the time of processing, it is preferable that the upper surface of the thin glass 6 to be processed is pressed from above by a known means such as a holding frame 11 for holding a masking plate.

図４に、本発明に使用される、切り欠きを有するマスキングプレートの１例を示す。マスキングプレート２に設ける切り欠き２１は、後工程の研磨工程で切削される分を考慮して、前記薄板ガラス６をマスキングしたときに、破線で示した所望する孔及び／又は抉りの形状６１よりも0.2〜0.35mm内側の部分が露出するように、小さめに設けられる。本発明で使用するマスキングプレートは、１枚の薄板ガラスを個別にマスキングするものであってもよいが、作業効率を上げるため、2枚以上の薄板ガラスを同時にマスキングできるようにしてもよい。   FIG. 4 shows an example of a masking plate having a notch used in the present invention. The notch 21 provided in the masking plate 2 is based on a desired hole and / or ridge shape 61 indicated by a broken line when the thin glass 6 is masked in consideration of a portion to be cut in a subsequent polishing step. Also, it is provided small so that the inner part of 0.2 to 0.35 mm is exposed. The masking plate used in the present invention may individually mask one thin glass plate, but may be configured to simultaneously mask two or more thin glass plates in order to increase working efficiency.

前記マスキングプレートに設けられた切り欠き部から露出した薄板ガラス６の部分を、サンドブラスト手段３を用いて切削する。この場合、サンドブラストのノズル３１は、コンピューター数値制御（CNC）により、薄板ガラス６の露出部外週に沿って研磨剤粒子を吹き付けながら移動する。   The portion of the thin glass 6 exposed from the notch provided in the masking plate is cut using the sand blasting means 3. In this case, the sandblast nozzle 31 is moved by spraying abrasive particles along the weeks outside the exposed portion of the thin glass 6 by computer numerical control (CNC).

本発明におけるサンドブラストに用いる研磨剤粒子は、例えばアルミナ、ジルコニア、チタニア等の、公知の研磨剤粒子の中から適宜選択して使用することができる。研磨剤粒子の粒径は特に制限されるものではないが、100〜120メッシュであることが好ましい。100メッシュのものより粒径が大きいと、薄板ガラス６を破損するおそれがあり、120メッシュのものより粒径が小さいと、効率的に薄板ガラス６を切削できなくなる。   The abrasive particles used for sandblasting in the present invention can be appropriately selected from known abrasive particles such as alumina, zirconia, titania and the like. The particle size of the abrasive particles is not particularly limited, but is preferably 100 to 120 mesh. If the particle size is larger than that of 100 mesh, the thin glass 6 may be damaged. If the particle size is smaller than 120 mesh, the thin glass 6 cannot be cut efficiently.

また、サンドブラストの吹き付けの圧力は特に制限されるものではないが、500〜600kPaであることが好ましい。吹き付けの圧力が500kPaより小さいと効率的に切削することができず、600kPaより大きいと、薄板ガラス６が破損するおそれがある。   Further, the pressure of sandblasting is not particularly limited, but is preferably 500 to 600 kPa. If the pressure of spraying is less than 500 kPa, cutting cannot be performed efficiently, and if it is greater than 600 kPa, the thin glass 6 may be damaged.

本発明のサンドブラスト装置は、切り替え手段によって研磨剤粒子の粒径を変えられる装置であることが好ましい。研磨粒子の粒径を変えることによって、粗切削のみならず精密な切削も可能となるからである。研磨粒子の粒径によって、ノズル径を切り替えて変更するか交換することが好ましい。しかしながら、本発明においては、サンドブラストを一定の粒径の研磨材で行い、後記するように、後工程の研磨工程で粗研磨及び仕上げ研磨をしてもよいし、必要に応じて、サンドブラスト工程と研磨工程の両方をそれぞれ２段ずつ行っても良い。   The sandblasting apparatus of the present invention is preferably an apparatus that can change the particle size of the abrasive particles by the switching means. This is because by changing the particle size of the abrasive particles, not only rough cutting but also precise cutting becomes possible. It is preferable to change or replace the nozzle diameter depending on the particle size of the abrasive particles. However, in the present invention, sand blasting is performed with an abrasive having a constant particle size, and as described later, rough polishing and finish polishing may be performed in a subsequent polishing step, and if necessary, a sand blasting step and Both of the polishing steps may be performed in two stages.

前記研磨装置は、前記サンドブラスト手段により切削された薄板ガラスを、予め定められた位置に固定する手段を有するテーブル４、及び前記サンドブラスト手段により切削された部分の端面を研磨する研磨手段５を有する。
前記サンドブラスト装置により切削された薄板ガラス６は、切削された面を整え、予め定められた孔及び／又は抉りの形状に調整するため研磨装置を用いて研磨される。 The polishing apparatus includes a table 4 having means for fixing the thin glass cut by the sand blasting means to a predetermined position, and polishing means 5 for polishing the end face of the portion cut by the sand blasting means.
The thin glass 6 cut by the sand blasting apparatus is polished using a polishing apparatus in order to adjust the cut surface and adjust the shape to a predetermined hole and / or grooving shape.

研磨手段５としては、通常、ダイヤモンドを使用した回転式の砥石５１を用いる。回転式の砥石５１は、CNCにより、薄板ガラスの縦横及び厚さ方向に移動することが可能であり、薄板ガラスの切削部の端部６２を、所望する孔及び／又は抉りの形状になるように、切削及び研磨する。本発明で使用する回転式の砥石５１としては、通常、500〜800番で、直径が0.2mm以下のものを使用する。   As the polishing means 5, a rotary grindstone 51 using diamond is usually used. The rotary grindstone 51 can be moved in the vertical and horizontal directions and in the thickness direction of the thin glass by the CNC so that the end 62 of the thin glass cutting portion has a desired hole and / or round shape. Then, cut and polish. As the rotating grindstone 51 used in the present invention, one having a number of 500 to 800 and a diameter of 0.2 mm or less is usually used.

図５に、本発明で使用する研磨装置の概略図を示す。
切削部端部の研磨は、薄板ガラス６をテーブル４上に位置決めした後、固定して行う。位置決めの手段は、図３で表されるような、前記サンドブラスト装置の場合と同様の手段でよい。また位置決め後の固定手段も、前述したサンドブラストの場合と同様に、公知の真空吸着による固定手段であることが好ましい。 FIG. 5 shows a schematic view of a polishing apparatus used in the present invention.
Polishing of the end portion of the cutting portion is performed after the thin glass 6 is positioned on the table 4 and then fixed. The positioning means may be the same as that in the case of the sandblasting device as shown in FIG. Also, the fixing means after positioning is preferably a well-known fixing means by vacuum suction as in the case of the sandblast described above.

本発明においては、研磨時のテーブルとサンドブラスト時のテーブルを共通にしてもよい。何れにしても、研磨を行う場合に用いる薄板ガラス６を固定するテーブルには、研磨手段の先端を逃すため、孔及び／又は抉りに対応する箇所に、所望する該孔及び／又は抉りよりも大きめの孔４２を開けておくか、それに替わるスペーサー又は板を配置する必要がある。   In the present invention, the table for polishing and the table for sandblasting may be shared. In any case, the table for fixing the thin glass 6 used when polishing is used, in order to escape the tip of the polishing means, so that the position corresponding to the hole and / or sag is more than the desired hole and / or sag. It is necessary to open a large hole 42 or to arrange a spacer or plate in place of it.

本発明における研磨装置は、粗研磨手段と仕上げ研磨手段を、交換可能に有することが好ましい。即ち、サンドブラスト工程の仕上がり具合や、目標精度に応じて、先ず粗研磨によって所望の孔及び／又は抉りより0.25〜0.2mm内側までを切削し、仕上げ研磨によって、所望の孔及び／又は抉りの形状となるように研磨しても良いし、サンドブラスとによって所望の孔及び／又は抉りより0.25〜0.2mm内側までを切削した場合には、粗研磨を省略し、仕上げ研磨だけを行っても良い。回転式の砥石５１として、粗研磨では、500〜600番のものを使用し、仕上げ研磨では、800番程度のものを使用する。   The polishing apparatus in the present invention preferably has a rough polishing means and a final polishing means in an exchangeable manner. That is, depending on the finish of the sandblasting process and the target accuracy, first cut the desired holes and / or 0.25 to 0.2 mm inside by rough polishing, and finish polishing to form the desired holes and / or edges. It may be polished so as to be, or when the desired hole and / or 0.25 to 0.2 mm inside is cut from the hole by sandblasting, rough polishing may be omitted and only final polishing may be performed. . As the rotary grindstone 51, those of No. 500 to 600 are used for rough polishing, and those of No. 800 are used for finish polishing.

本発明の薄板ガラスの加工装置は、厚さが0.5〜1.1mmの薄板ガラスに、迅速且つ高精度で孔や抉り等を設けることができるので、携帯電話等の機器類の表示窓に、スピーカー孔やスイッチ取り付け孔等を設ける場合に有用である。   The thin glass processing apparatus of the present invention can quickly and accurately provide holes and swells in a thin glass sheet having a thickness of 0.5 to 1.1 mm, so that a speaker is displayed on a display window of a device such as a mobile phone. This is useful when holes or switch mounting holes are provided.
