Abstract

<P>PROBLEM TO BE SOLVED: To provide a scribing device which enables a large-area hard brittle sheet to be worked by acquiring a technical means which helps scribe (including breakless scribing) the large-area hard brittle sheet using a small-area platen. <P>SOLUTION: The scribing device comprises the platen 2 with a shorter feed direction size than the feed direction size of a work to be fed, a forward conveyor 3 and a rear conveyor 4 arranged at the forward and backward positions of the feed direction of the platen 2 and a gyrating lifter 5 arranged in the center of either of the conveyors 3 and 4. The platen 2 is of a slender band shape in an orthogonal direction with the feed direction of the work and has a far smaller area than the size of the work. Thus the device is lightweight and the platen 2 is easily worked. The hard brittle sheet 1 to be split is fed onto the platen 2 by the feed operation of the conveyors 3 and 4 and the splitting position is set on the platen 2 by stopping the conveyors 3 and 4 at a desired position. The splitting position is also set by inching or fine-gyrating the platen 2 or a scribing head according to necessity. <P>COPYRIGHT: (C)2004,JPO

Description

【０００１】
【発明の属する技術分野】
この発明は、硬質脆性板のスクライブ装置、特にディスプレイパネル用のガラス基板などを所望寸法に割断するために、当該基板などの表面に交差する縦横のスクライブ線（引っ掻き溝）を刻設するのに適した装置に関するものである。
【０００２】
【従来の技術】
液晶ディスプレイパネルなどの製造には、大きなガラス基板を縦横に割断（割って切断）する工程が必要で、この工程を行うためにスクライブ装置が用いられている。ガラス基板などの硬質脆性板の割断には、板表面に溝ないし微小クラックを形成するスクライブ工程と、形成したスクライブ線に沿って分離するブレーク工程とで行うのが一般的であるが、スクライブと同時に板を分断するブレークレススクライブという方法も試みられている。スクライブ線の刻設は、レーザビームで行う方法も提案されているが、一般的には回転カッタを割断線に沿って転動させる方法が採用されており、この際にはワークとなる硬質脆性板が定盤上にしっかりと固定されていることが必要である。
【０００３】
ディスプレイパネルの大面積化と生産性を上げるための多数個取りの要請から、割断対象となる硬質脆性板の面積が大きくなる。その結果スクライブ装置は、大型のワークをしっかりと固定するための大面積の定盤を必要とし、この定盤を移動させて割断位置の位置決めを行い、またこの定盤を旋回して互いに交差する方向のスクライブ線の刻設を可能にしている。
【０００４】
【発明が解決しようとする課題】
スクライブの際に硬質脆性板に形成される溝やクラックの性状を一定にして、欠けや割れなどのない割断パネルを歩留まりよく得るためには、精度の高い定盤面が必要である。そのため、定盤面積が大きくなると、定盤の加工に大型で高精度の工作機械と長い加工時間とを必要とし、定盤の加工コストが上昇し、スクライブ装置が高価になる。
【０００５】
この発明は、面積の狭い定盤で大面積の硬質脆性板のスクライブ（ブレークレススクライブを含む）を可能にする技術手段を得ることにより、大面積の硬質脆性板の加工が可能なスクライブ装置を安価に提供することを課題としている。
【０００６】
【課題を解決するための手段】
この発明のスクライブ装置は、ワークを定盤に固定した状態で当該ワークの送り方向と直交する方向のスクライブ線を刻設する硬質脆性板のスクライブ装置において、送り込まれるワークの送り方向寸法Ｌ１、Ｌ２・・・より短い送り方向寸法を備えた上記定盤２と、当該定盤の送り方向前後に配置された前コンベア３及び後コンベア４と、当該コンベアの一方の中央部に設けられた旋回リフタ５とを備えている。
【０００７】
定盤２は、ワークの送り直角方向に細長い帯板状のものとし、その幅（ワーク送り方向の寸法）は、加工前のワークや割断パネル（割断された後のパネル）が定盤２から前後方向に突出して、その突出部分が前後のコンベア３、４で支持される寸法にする。定盤２の面積は、ワーク寸法に比べてはるかに小さくなり、機械を軽量化できると共に定盤２の加工が容易になる。前後のコンベア３、４は、一般的にはベルトコンベア又はローラコンベアである。旋回リフタ５としては、コンベア３の上面より高く上昇する載荷面を備えた構造や、硬質脆性板の上面を吸着して当該板をコンベア上から持ち上げて旋回する構造のものを採用できる。旋回リフタ５の昇降（リフト）は、コンベア面に対して相対的なものであればよい。
【０００８】
上記装置において、割断しようとする硬質脆性板１は、前コンベア３に載せられ、コンベア３、４の送り動作により定盤２上へと送られる。所望位置でコンベア３、４を停止することにより、割断位置を定盤２上に位置させ、必要なら当該定盤やスクライブヘッドの微小移動や微小旋回により割断位置を設定する。そして、従来と同様に回転カッタ１４を走行させるなどして、硬質脆性板上にスクライブ線を刻設する。スクライブ線を刻設したら、再びコンベア３、４を駆動してワークを送り、次の割断位置を定盤２上に位置させる。
【０００９】
このような操作を繰り返して硬質脆性板の第１の方向のスクライブ線を刻設したら、旋回リフタ５の位置にワークを運搬して停止し、この位置で旋回リフタ５が上昇、旋回及び下降してワークを新たな方向に向ける。旋回リフタ５の上昇及び下降は、コンベア３に対する相対的なものである。そして、新たな方向に向けた硬質脆性板に第１の方向のスクライブ線を刻設したと同じ手順により、第２の方向のスクライブ線を刻設して、後コンベア４からクロススクライブされたワークを次の工程へと送り出す。
【００１０】
ブレークレススクライブを行うときは、スクライブ線の刻設と同時に硬質脆性板が分断される。割断パネルは、定盤２の前後のコンベア３、４の駆動開始タイミングに差を持たせることにより、相互の間に間隔を持たせて搬送する。この操作を実現するために、請求項２の発明では、前コンベア３と後コンベア４とが同一速度で駆動されかつその駆動開始及び停止タイミングを個別に制御可能に設けている。
【００１１】
上記装置おいて、第１の方向にブレークレススクライブされた割断パネルを、コンベア３、４の異なるタイミングでの駆動により、相互に間隔を隔てて搬送し、先頭の割断パネルが旋回リフタ５の位置に来たときに、コンベア３、４を停止して、旋回リフタ５で最初の割断パネルを第２の方向に向け、次に２番目の割断パネルを旋回リフタ５の位置に送って第２の方向に向けるという動作で、割断パネルの向きを変え、かつ先頭の割断パネルから順に第２の方向の割断位置を定盤２上に送って、第２の方向のブレークレススクライブを行う。縦横に割断されたパネルは、後コンベア４から順次次工程に搬送される。
【００１２】
【発明の実施の形態】
以下、図面に示す実施例を参照して、この発明のスクライブ装置と当該装置を使用したクロススクライブ方法を説明する。図１は、スクライブ装置を示す斜視図で、割断するガラス板１（図１に想像線で示されている）の送り方向と直交する装置幅方向に細長い定盤２と、その送り方向前後に配置したコンベア３、４と、前コンベア３の中間に配置した旋回リフタ５とを備えている。
【００１３】
定盤２の上方には、装置幅方向の走行桁１０が設けられ、この走行桁に沿って走行する走行台１１が設けられている。走行台１１には、ワーク送り方向に微小移動可能に取付板１２が装着され、この取付板に付勢装置１３を介して回転カッタ１４が搭載されている。定盤２は、機台１５に固定して設けられており、コンベア３、４で定盤２上へ送られたガラス板の微小な停止位置誤差は、取付板１２をワーク送り方向に微小移動させることによって補正し、また、ガラス板の微小な傾きは、走行台１１の装置幅方向の走行距離に比例して取付板１２をワーク送り方向に微小移動させることにより修正して、回転カッタ１４を所望の切断線に沿って走行させる。
【００１４】
定盤２の上面には、多数の空気孔６が設けられており、これらの空気孔は図示しない切換弁を介して負圧空気源と加圧空気源とに連結されている。定盤２上に送り込まれたガラス板は、この空気孔に供給した負圧で吸着された状態でスクライブ加工される。一方コンベア３、４を駆動してガラス板を搬送するときは、この空気孔に加圧空気を供給してガラス板を定盤２の上面から浮かせた状態で行う。
【００１５】
図の実施例では、コンベア３、４は、装置幅方向に並置されて同期駆動される４本のコンベアベルトを備えている。前コンベア３においては、内側のコンベアベルト７が送り方向上流側と下流側とに分割して設けられており、その間の位置に旋回リフタ５が配置されている。旋回リフタの旋回台８は、その下部に図示されていない旋回駆動装置と昇降駆動装置とを備えており、旋回台８の上面に４本の支持ピン９が立設されている。前記昇降駆動装置が支持ピン９を上昇させたとき、これらの４本の支持ピンが前コンベア３上のガラス板を持ち上げる。
【００１６】
各コンベア３、４におけるコンベアベルトないしコンベアローラの配置は、一定寸法の板材を加工するのか、大小様々な大きさの板材を加工するのかを考慮して、板材を撓ませないで支持できるように配置する。前コンベア３と後コンベア４とは、１個又は複数のモータで同期駆動される。ブレークレススクライブを行うときは、前コンベア３と後コンベア４とを個別のモータで駆動するか、それらの駆動伝達系にクラッチを設けて、前後のコンベア３、４を個別のタイミングで駆動できるようにする。コンベア駆動用のモータは、図には示してないが、サーボモータを用いることにより、コンベア３、４で搬送するガラス板の定盤２上での停止位置を高い精度で制御することができる。
【００１７】
図２及び３は、図１のスクライブ装置におけるクロススクライブ方法を模式的に示した図である。図２は通常のスクライブ（次段のブレーク工程で分断するスクライブ）の場合を示し、図３はブレークレススクライブ（ブレーク工程を設けないでスクライブ時に分断する）の場合を示している。
【００１８】
通常のスクライブの場合には、前コンベア３上に送り込まれたガラス板１をコンベア３、４で送って、その割断位置を定盤２上に位置決めし、コンベア３、４を停止し、ガラス板１を定盤２上に負圧吸着した状態で回転カッタ１４を走行させて、第１の方向のスクライブ線を刻設する。ガラス板１の停止位置誤差や傾き誤差への対応は、前述したように回転カッタを装着した取付板１２を微小移動させることにより行っているが、定盤２の微小移動機構を設けて行うこともできる。
【００１９】
第１の方向のスクライブ線を２本以上刻設するときは、その間隔分だけコンベア３、４を駆動して複数の割断位置を順次定盤２上に位置決めして、所望の本数のスクライブ線を刻設する。次にコンベア３、４を反転して、ガラス板１を旋回リフタ５の真上の位置に戻し、旋回リフタ５の上昇、旋回及び下降の動作により、ガラス板１を９０度旋回させる。そして、再びコンベア３、４を駆動し、第２の方向の割断位置を定盤２上に位置決めして、第２の方向のスクライブ線を刻設する。所定のスクライブ線の刻設が完了したら、後コンベア４でガラス板を図示しない次工程のブレーク装置に搬送する。
【００２０】
ブレークレススクライブの場合には、第１の方向のスクライブ線を刻設したときに、ガラス板は当該スクライブ線に沿って分断される。そこで図３に示すように、スクライブ後、後コンベア４のみを駆動して、分断されたガラス板相互の間に間隔を開ける。所定の間隔が開いたら、コンベア３、４を同期駆動して、次の割断位置を定盤２上に位置決めする。この動作を繰り返すことで、第１の方向にブレークレススクライブされた割断パネル相互は、所定の間隔を隔てて後コンベア４上に送り出される。この状態から、コンベア３、４を逆回転し、先頭の（最初に分断された）割断パネルが旋回リフタ５の位置にきたときにコンベア３、４を停止し、旋回リフタ５で当該割断パネルを９０度旋回する。そして、コンベア３、４を再び順送り方向に駆動し、旋回後のパネルの第２の方向の割断位置が定盤２上に来たときには、コンベア３、４を停止して第２の方向のブレークレススクライブを行い、旋回前の割断パネルが旋回リフタ５の位置に来たときには、コンベア３、４を停止して、旋回リフタで当該割断パネルを９０度旋回するという動作を繰り返すことにより、最終寸法に割断されたガラス板が後コンベア４から順次次工程へ送り出される。
【００２１】
以上の説明から理解されるように、ブレークレススクライブの場合には、個々の割断パネルの旋回に必要な間隔を割断パネル相互の間に持たせるために、コンベア３、４の異なるタイミングでの起動停止が必要である。
【００２２】
【発明の効果】
以上説明したこの発明のスクライブ装置によれば、定盤２の面積を小さくすることができ、精度の高い定盤を安価に製造することができるので、大面積のガラス板のスクライブが可能な装置を安価に提供できるという効果がある。また、この発明の装置では、同一機台上でガラス板に縦横方向のスクライブ線を刻設することができ、スクライブと同時にガラス板が分断されるブレークレススクライブにおいても、縦横両方向の加工を同一機台上で行うことができるという効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention is intended to cut longitudinal and horizontal scribing lines (scratch grooves) intersecting the surface of a substrate such as a scribing device for cutting a hard brittle plate, particularly a glass substrate for a display panel, into a desired size. It concerns a suitable device.
[0002]
[Prior art]
Manufacturing of a liquid crystal display panel or the like requires a process of cutting (cutting) a large glass substrate vertically and horizontally, and a scribe device is used to perform this process. The cutting of a hard brittle plate such as a glass substrate is generally performed by a scribing process of forming grooves or minute cracks on the plate surface and a breaking process of separating along a formed scribe line. At the same time, a method called breakless scribing, which divides the board, has been attempted. A method of engraving a scribe line using a laser beam has been proposed, but a method of rolling a rotary cutter along a cutting line is generally employed, and in this case, a hard brittle material serving as a work is used. The board must be firmly fixed on the surface plate.
[0003]
Due to a demand for a large-sized display panel and a large number of pieces to increase productivity, the area of the hard brittle plate to be cut becomes large. As a result, the scribing device requires a large surface plate to firmly fix a large work, moves the platen to position the cutting position, and turns the surface plate to cross each other. It is possible to engrave scribe lines in different directions.
[0004]
[Problems to be solved by the invention]
In order to make the properties of the grooves and cracks formed in the hard brittle plate during scribing constant and to obtain a cut panel without chipping or cracking with good yield, a highly accurate surface plate surface is required. Therefore, when the surface area of the surface plate becomes large, a large and high-precision machine tool and a long processing time are required for processing the surface plate, the processing cost of the surface plate increases, and the scribe device becomes expensive.
[0005]
The present invention provides a scribing apparatus capable of processing a large-area hard brittle plate by obtaining technical means that enables scribing (including breakless scribe) of a large-area hard brittle plate on a small surface plate. The task is to provide it at low cost.
[0006]
[Means for Solving the Problems]
The scribing device according to the present invention is a scribing device of a hard brittle plate for engraving a scribe line in a direction orthogonal to a feed direction of the work while the work is fixed to a surface plate. ... the platen 2 having a shorter dimension in the feed direction, the front conveyor 3 and the rear conveyor 4 arranged before and after the platen in the feed direction, and a swing lifter provided at one central portion of the conveyor. 5 is provided.
[0007]
The platen 2 has a strip shape elongated in the direction perpendicular to the feed direction of the workpiece. The width (dimensions in the workpiece feed direction) of the workpiece before processing and the cleaving panel (panel after being cleaved) are from the platen 2 It protrudes in the front-rear direction, and the protruding portion is dimensioned to be supported by the front and rear conveyors 3 and 4. The area of the surface plate 2 is much smaller than the size of the work, so that the weight of the machine can be reduced and the surface plate 2 can be easily processed. The front and rear conveyors 3 and 4 are generally belt conveyors or roller conveyors. As the revolving lifter 5, a structure having a loading surface that rises higher than the upper surface of the conveyor 3 or a structure that adsorbs the upper surface of a hard brittle plate and lifts the plate from the conveyor to revolve can be adopted. The lift (lift) of the swing lifter 5 may be any relative to the conveyor surface.
[0008]
In the above-described apparatus, the hard brittle plate 1 to be cut is placed on the front conveyor 3 and is sent onto the surface plate 2 by the feeding operation of the conveyors 3 and 4. By stopping the conveyors 3 and 4 at a desired position, the cutting position is positioned on the surface plate 2, and if necessary, the cutting position is set by minute movement or small rotation of the surface plate or the scribe head. Then, a scribe line is carved on the hard brittle plate by, for example, running the rotary cutter 14 as in the related art. After the scribe line is engraved, the conveyors 3 and 4 are driven again to feed the work, and the next cutting position is positioned on the surface plate 2.
[0009]
After the above operation is repeated and a scribe line in the first direction of the hard brittle plate is engraved, the work is transported to the position of the turning lifter 5 and stopped, and the turning lifter 5 rises, turns and descends at this position. Orient the work in a new direction. The lifting and lowering of the swivel lifter 5 is relative to the conveyor 3. Then, a scribe line in the second direction is engraved in the same procedure as the scribe line in the first direction is engraved on the hard and brittle plate in a new direction, and the work cross-scribed from the rear conveyor 4 is formed. To the next step.
[0010]
When performing a breakless scribe, the hard brittle plate is cut at the same time as the scribe line is carved. The split panels are conveyed with an interval between them by giving a difference in the drive start timing of the conveyors 3 and 4 before and after the platen 2. In order to realize this operation, in the invention of claim 2, the front conveyor 3 and the rear conveyor 4 are driven at the same speed, and the drive start and stop timings thereof are provided so as to be individually controllable.
[0011]
In the above-mentioned apparatus, the break panels scribed breaklessly in the first direction are transported at an interval from each other by driving the conveyors 3 and 4 at different timings. , The conveyors 3 and 4 are stopped, the first split panel is turned in the second direction by the swivel lifter 5, and the second split panel is sent to the position of the second lift With the operation of turning in the direction, the direction of the cutting panel is changed, and the cutting position in the second direction is sequentially sent to the surface plate 2 from the leading cutting panel to perform the breakless scribe in the second direction. The panels cut vertically and horizontally are sequentially conveyed from the rear conveyor 4 to the next process.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a scribe device of the present invention and a cross scribe method using the device will be described with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing a scribing device, and a platen 2 elongated in a device width direction orthogonal to a feeding direction of a glass plate 1 to be cut (indicated by imaginary lines in FIG. 1), and before and after the feeding direction. The conveyor 3 includes the arranged conveyors 3 and 4 and the turning lifter 5 arranged in the middle of the front conveyor 3.
[0013]
A traveling girder 10 in the apparatus width direction is provided above the surface plate 2, and a traveling platform 11 traveling along the traveling girder is provided. A mounting plate 12 is mounted on the traveling table 11 so as to be able to move minutely in the workpiece feed direction, and a rotary cutter 14 is mounted on the mounting plate via an urging device 13. The platen 2 is fixed to the machine base 15, and a slight stop position error of the glass plate sent onto the platen 2 by the conveyors 3, 4 causes the mounting plate 12 to move slightly in the workpiece feed direction. The small inclination of the glass plate is corrected by slightly moving the mounting plate 12 in the workpiece feed direction in proportion to the traveling distance of the traveling base 11 in the apparatus width direction. Along the desired cutting line.
[0014]
A large number of air holes 6 are provided on the upper surface of the surface plate 2, and these air holes are connected to a negative pressure air source and a pressurized air source via a switching valve (not shown). The glass plate fed onto the platen 2 is scribed while being sucked by the negative pressure supplied to the air holes. On the other hand, when driving the conveyors 3 and 4 to convey the glass plate, pressurized air is supplied to the air holes and the glass plate is floated from the upper surface of the platen 2.
[0015]
In the illustrated embodiment, the conveyors 3 and 4 include four conveyor belts which are arranged side by side in the apparatus width direction and driven synchronously. In the front conveyor 3, the inner conveyor belt 7 is divided into an upstream side and a downstream side in the feeding direction, and the turning lifter 5 is disposed at a position between them. The swivel 8 of the swivel lifter is provided with a swivel drive and a lift drive (not shown) at its lower part, and four support pins 9 are provided upright on the upper surface of the swivel 8. When the lifting drive raises the support pins 9, these four support pins lift the glass plate on the front conveyor 3.
[0016]
The arrangement of the conveyor belt or the conveyor roller in each of the conveyors 3 and 4 is designed so that the plate material can be supported without bending in consideration of processing a plate material of a fixed size or a plate material of various sizes. Deploy. The front conveyor 3 and the rear conveyor 4 are synchronously driven by one or a plurality of motors. When performing a breakless scribe, the front conveyor 3 and the rear conveyor 4 may be driven by separate motors or a clutch may be provided in their drive transmission system so that the front and rear conveyors 3 and 4 can be driven at separate timings. To Although a motor for driving the conveyor is not shown in the figure, a stop position of the glass plate conveyed by the conveyors 3 and 4 on the surface plate 2 can be controlled with high accuracy by using a servomotor.
[0017]
2 and 3 are diagrams schematically showing a cross scribe method in the scribe device of FIG. FIG. 2 shows the case of a normal scribe (scribed in the next break step), and FIG. 3 shows the case of breakless scribe (divided at the time of scribe without providing a break step).
[0018]
In the case of a normal scribe, the glass plate 1 sent on the front conveyor 3 is sent by the conveyors 3 and 4, the cutting position is positioned on the surface plate 2, and the conveyors 3 and 4 are stopped. The rotary cutter 14 is caused to travel in a state where 1 is suction-adsorbed onto the surface plate 2 to cut a scribe line in the first direction. The stop position error and the tilt error of the glass plate 1 are dealt with by slightly moving the mounting plate 12 on which the rotary cutter is mounted as described above. You can also.
[0019]
When engraving two or more scribe lines in the first direction, the conveyors 3 and 4 are driven by the distance between the scribe lines and a plurality of cutting positions are sequentially positioned on the surface plate 2 so that a desired number of scribe lines are formed. Is engraved. Next, the conveyors 3 and 4 are turned over, the glass plate 1 is returned to a position immediately above the turning lifter 5, and the glass plate 1 is turned 90 degrees by the upward, turning and lowering operations of the turning lifter 5. Then, the conveyors 3 and 4 are driven again, the cutting position in the second direction is positioned on the surface plate 2, and a scribe line in the second direction is carved. When the engraving of the predetermined scribe line is completed, the glass sheet is conveyed by the post-conveyor 4 to a break device in a next step (not shown).
[0020]
In the case of a breakless scribe, when a scribe line in the first direction is carved, the glass plate is cut along the scribe line. Therefore, as shown in FIG. 3, after scribing, only the rear conveyor 4 is driven to leave an interval between the divided glass plates. When a predetermined interval is opened, the conveyors 3 and 4 are driven synchronously to position the next cutting position on the surface plate 2. By repeating this operation, the split panels that have been breaklessly scribed in the first direction are sent out onto the rear conveyor 4 at predetermined intervals. From this state, the conveyors 3 and 4 are rotated in the reverse direction, and the conveyors 3 and 4 are stopped when the leading (first divided) split panel comes to the position of the turning lifter 5. Turn 90 degrees. Then, the conveyors 3 and 4 are driven again in the forward direction, and when the cut position of the panel in the second direction after turning is on the surface plate 2, the conveyors 3 and 4 are stopped to break in the second direction. When the scribing panel before turning comes to the position of the turning lifter 5 by performing a rescue scribe, the conveyors 3 and 4 are stopped, and the operation of turning the cutting panel by 90 degrees by the turning lifter is repeated, so that the final dimensions are obtained. The glass sheet cut into pieces is sequentially sent out from the rear conveyor 4 to the next process.
[0021]
As can be understood from the above description, in the case of the breakless scribe, the conveyors 3 and 4 are started at different timings in order to provide an interval required for turning the individual split panels between the split panels. A stop is required.
[0022]
