Description

この発明は、大判なガラス基板に大割の切断線を入れて大割し、この大割したガラス基板に小割の切断線を入れて製品サイズに小割するガラス基板の切断、分断方法及びその装置に関する。   The present invention relates to a method for cutting and dividing a glass substrate by dividing a large glass substrate with a large cutting line and dividing the large glass substrate with a small cutting line to make a product size. It relates to the device.
大判なガラス基板(片面に膜を設けてある例えば液晶パネル)から製品サイズのガラス基板を得るには、ガラス基板の膜のない面、すなわち、下面に切断線を入れたのち、ガラス基板の上面に応力を加えて割断する(特許文献1)。   In order to obtain a product-sized glass substrate from a large glass substrate (for example, a liquid crystal panel provided with a film on one side), a cutting line is made on the surface of the glass substrate without a film, that is, the lower surface, and then the upper surface of the glass substrate. The material is cleaved by applying stress (Patent Document 1).
また、切断線を入れたガラス基板は、ガラス基板の保持ステージの切断線の片側を上昇方向に傾動しながら、切断線を分断して大割する(特許文献2)。
特開平8−133774号公報 特開平8−283033号公報
Moreover, the glass substrate into which the cutting line is put is divided by cutting the cutting line while tilting one side of the cutting line of the holding stage of the glass substrate in the upward direction (Patent Document 2).
JP-A-8-133774 JP-A-8-283033
ところで、特許文献1の割断方法は、テーブル上にガラスパネルを載置したのち、テーブルに沿って移動するカッタによってガラスパネルの下面でテーブルにより覆われない部分にカッタによりガラスパネルの一端縁から他端縁にまで達するように条痕を形成し、次いでガラスパネルの上面側から上記条痕の形成部分に応力を加えて大割割断する方式のため、大判なガラスパネルから大割パネルの分断のみで、大割パネルをさらに製品サイズの小割パネルに分断するには、次の小割加工機(条痕加工及び応力を加える割断加工を行なう)に搬入しなければならない。   By the way, the cleaving method of Patent Document 1 is such that after placing the glass panel on the table, the cutter moves from the one end edge of the glass panel to the portion that is not covered by the table on the lower surface of the glass panel. Since the striations are formed so as to reach the edge, and then the crevice formation is performed by applying stress to the formation of the streaks from the upper surface side of the glass panel, only the division of the large panel from the large glass panel. In order to further divide the large panel into product-sized small panels, it must be carried into the next small cutting machine (which performs streaking and cleaving that applies stress).
このため、大割から小割迄の加工能率が著しく低下すると共に、大割と小割の二台の加工機を必要とするため、設備費が大幅に高騰する問題もあった。   For this reason, the machining efficiency from the large part to the small part is remarkably lowered, and two processing machines, a large part and a small part, are required, so that there is a problem that the equipment cost is significantly increased.
また、特許文献2のガラス基板のカット方法は、ガラス基板の電極パターンの形成されていない面を吸着保持すると共に、保持状況下に保持側面にスクライブラインを入れたのち、カット位置の両側を吸着保持ステージの上昇傾動により相対的に折り曲げて大割分割する方式のため、大割から製品サイズの小割迄の一連の分断が一台の加工機ではできない。   In addition, the glass substrate cutting method of Patent Document 2 sucks and holds the surface of the glass substrate where the electrode pattern is not formed, and puts a scribe line on the holding side surface under the holding state, and sucks both sides of the cutting position. Because of the method of relatively bending and dividing into large parts by ascending tilt of the holding stage, a series of divisions from a large part to a small part of the product size cannot be performed with a single processing machine.
このため、大割、小割の二台の加工機が必要になると共に、大幅な能率低下やコストのアップになるなどの問題が発生した。   For this reason, two processing machines, large and small, are required, and problems such as a significant reduction in efficiency and an increase in cost have occurred.
そこで、この発明は、大判なガラス基板を供給することで、まず切断線(スクライブライン)を入れて、この切断線の部分を分断して大割ガラス基板に分割し、この分割された大割ガラス基板に切断線(スクライブライン)を入れて、この切断線の部分を分断して製品サイズの小割ガラス基板に分割するようにしたガラス基板の切断、分断装置を提供する。   Therefore, the present invention supplies a large glass substrate, first puts a cutting line (scribe line), divides the cutting line portion and divides it into a large glass substrate. Provided is a glass substrate cutting and cutting apparatus in which a cutting line (scribe line) is inserted into a glass substrate, and the portion of the cutting line is divided to divide into a small glass substrate having a product size.
上記の課題を解決するために、この発明は、第1テーブル上の定位置に上面に膜面を有するガラス基板を搬入したのち、上記第1テーブルのガラス基板搬入方向に沿う少なくとも1条の走行路内の第1カッタの走行により前記ガラスの下面に第1切断線を入れ、次いで前方の第2テーブル上に搬出手段により、上記ガラス基板を所定の長さ搬出後、上記第1テーブルと第2テーブルとの間で走行する第2カッタによりガラス基板の下面に上記第1切断線を横切る第2切断線を入れ、その後に上記第2切断線の直上に第1分断手段の応力を加えて分断し、分断された大割ガラス基板を搬出手段により搬出し、搬出途中に大割ガラス基板を旋回手段により90度旋回したのち、分断位置に到達した上記大割ガラス基板の第1切断線の直上に第2分断手段の応力を加えて分断することを特徴とするガラス基板の切断、分断方法を採用する。   In order to solve the above-mentioned problems, the present invention carries at least one run along the glass substrate loading direction of the first table after loading a glass substrate having a film surface on the upper surface at a fixed position on the first table. A first cutting line is made on the lower surface of the glass by traveling of the first cutter in the road, and then the glass substrate is unloaded for a predetermined length by the unloading means on the second table in front, and then the first table and the first table. A second cutting line that crosses the first cutting line is put on the lower surface of the glass substrate by a second cutter that travels between two tables, and then the stress of the first dividing means is applied immediately above the second cutting line. The divided glass substrate is unloaded by the unloading means, and the unfolded glass substrate is turned 90 degrees by the turning means in the middle of unloading, and then the first cutting line of the above-mentioned broken glass substrate that has reached the dividing position. The second minute directly above Cutting of the glass substrate, which comprises dividing by adding stress means, adopting the cutting method.
また、上面に膜面を有するガラス基板を荷受けする第1テーブルと、この第1テーブルに上記ガラス基板を定位置迄の搬入及び上記第1テーブルの前方に設けてある第2テーブル上への搬入をするように設けた第1搬送手段と、上記第1テーブルに上記ガラス基板の搬入方向に沿う少なくとも1条の走行路内で往復走行すると共に、前記ガラス基板の下面前後縁間に第1切断線を入れるように設けた第1カッタと、上記第1テーブルと第2テーブルとの間で往復走行すると共に、上記ガラス基板の両側縁間に第2切断線を入れるように設けた第2カッタと、この第2切断線に上方から応力を加えて分断するように設けた第1分断手段と、第テーブル上の大割ガラス基板を前方に搬送するように設けた前半第2搬送手段と、この前半第2搬送手段により搬送された上記大割ガラス基板を荷受け、荷受け後に90度旋回させるように設けた旋回装置と、この旋回した大割ガラス基板を荷受けして前方に設けてある第3テーブルに搬出するように設けた後半第2搬送手段と、上記大割ガラス基板の上記第2テーブルと第3テーブルとの間に位置する上記第1切断線に上方から応力を加えて分断するように設けた第2分断手段とからなるガラス基板の切断、分断装置を採用する。
Also, a first table for receiving a glass substrate having a film surface on the upper surface, and carrying the glass substrate to a fixed position on the first table and carrying it onto a second table provided in front of the first table. And a first cutting means between the front and rear edges of the lower surface of the glass substrate, and a reciprocating travel in at least one travel path along the loading direction of the glass substrate to the first table. A first cutter provided so as to insert a wire, and a second cutter provided so as to reciprocate between the first table and the second table and to insert a second cutting line between both side edges of the glass substrate. And a first dividing means provided so as to divide the second cutting line by applying stress from above, and a first half second conveying means provided so as to convey the large glass substrate on the second table forward. , the first half of the second transport And load receiving the large split glass substrate conveyed by stages, a turning device provided to pivot 90 degrees after consignment is unloaded in the third table is provided in the front to the load-receiving large split glass substrate This pivoting The second transport means provided in the latter half and the first cutting line positioned between the second table and the third table of the large glass substrate are provided so as to be divided by applying stress from above. A glass substrate cutting / cutting device comprising two cutting means is employed.
すると、大判なガラス基板を供給することで、第1カッタにより第1切断線を入れ、次いで第2カッタにより第1切断線を横切る第2切断線を入れ、この第2切断線を分断して大割ガラス基板を得る。   Then, by supplying a large glass substrate, a first cutting line is put by the first cutter, then a second cutting line crossing the first cutting line is put by the second cutter, and the second cutting line is divided. A large glass substrate is obtained.
そして、得られた大割ガラス基板を搬出し、かつ搬出途中に90度旋回したのち、第1切断線を分断して製品サイズの小割ガラス基板を一台の機械で能率よく得る。   And after carrying out the obtained large glass substrate and turning 90 degree | times in the middle of carrying out, a 1st cutting line is parted and the small glass substrate of a product size is efficiently obtained with one machine.
以上のように、この発明のガラス基板の切断、分断方法及びその装置によれば、一枚の大判なガラス基板に製品サイズの小割用の第1切断線を入れ、次いでガラス基板に大割用の第2切断線を入れて、この第2切断線を分断して大割ガラス基板に分断し、この分断した大割ガラス基板を搬出しながら、まず90度旋回し、次いで分断位置に送り込んで第1切断しながら製品サイズの小割ガラス基板に分断する一連の作業を一台の機械で行なうことができる。   As described above, according to the method and apparatus for cutting and dividing a glass substrate according to the present invention, a first cutting line for a product size is placed on one large glass substrate, and then the glass substrate is roughly divided. A second cutting line is inserted, and the second cutting line is divided into large glass substrates, and then the divided large glass substrate is unloaded and turned 90 degrees first, and then sent to the dividing position. Thus, a series of operations for dividing into a small glass substrate having a product size while performing the first cutting can be performed by one machine.
このため、切断線を入れて大判なガラス基板から大割ガラス基板を分断し、この分断しした大割ガラス基板に切断線を入れ、次に切断線を分断して製品サイズの小割ガラス基板とする大幅な能率低下をまねく二台の機械が不要になると共に、著しい能率の向上をはかる効果がある。   For this reason, a cutting glass is used to divide a large glass substrate from a large glass substrate, a cutting line is inserted into the divided large glass substrate, and then the cutting line is divided to produce a small glass substrate of a product size. This eliminates the need for two machines that cause a significant reduction in efficiency and significantly improves efficiency.
また、膜面を上側にしてガラス基板の裏面(下面)に大割、小割用の切断線を入れると共に、膜面の分断応力作用面を無接触で処理できるので、膜面の汚れや傷がつくようなこともない。   In addition, with the film surface facing upward, cutting lines for large and small portions are placed on the back surface (bottom surface) of the glass substrate, and the dividing stress acting surface of the film surface can be processed without contact. There's no such thing as
以下、この発明の実施の形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.
この発明の実施形態では、図1から図6に示すように、ローラコンベヤ1により第1テーブルAに搬入するガラス基板Xは、第1テーブルAに設けてある第1搬送手段Dにより前方の定位置迄送り込まれ、この送り込んだガラス基板Xを数値制御により大割ガラス基板Yに見合う長さ順次送り出されるようになっている。   In the embodiment of the present invention, as shown in FIGS. 1 to 6, the glass substrate X carried into the first table A by the roller conveyor 1 is fixed in front by the first transport means D provided on the first table A. The glass substrate X is fed to the position, and the fed glass substrate X is sequentially sent out by the numerical control to the length corresponding to the large glass substrate Y.
そして、第1テーブルA上に搬入したガラス基板Xは、第1テーブルAに設けてある搬入方向に沿う少なくとも1条の走行路2内で往復走行する第1カッタ3によりガラス基板Xの下面に小割用の第1切断線4が入るようになっている。   And the glass substrate X carried in on the 1st table A is made into the lower surface of the glass substrate X by the 1st cutter 3 which reciprocates in the at least 1 running path 2 along the carrying-in direction provided in the 1st table A. A first cutting line 4 for splitting is inserted.
勿論、第1カッタ3は、小割の枚数に応じて(図示1条から2条など)増設することもある。   Of course, the first cutter 3 may be added according to the number of pieces (one or two in the figure).
上記の第1搬送手段Dは、例えば図3に示すように、第1テーブルAの両側部にガラス基板Xの搬入方向に沿う走行路5を設けて、この走行路5の両端に片方をモーター(図示省略)により可逆駆動するスプロケット6と、このスプロケット6間にかけ渡したタイミングベルトなどの無端体7と、この無端体7に据え付けたシリンダ8の伸長作用により上昇してガラス基板Xの下面(膜のない裏面)を吸引する吸盤9とで構成し、吸盤9によるガラス基板Xの下面を吸引したのち、無端体7を走行させてガラス基板Xを搬入、搬出するようにしたが、その他の構成によって目的を達成するようにしてもよい。   For example, as shown in FIG. 3, the first transport means D is provided with a traveling path 5 along the loading direction of the glass substrate X on both sides of the first table A, and one motor is provided at both ends of the traveling path 5. The sprocket 6 reversibly driven (not shown), the endless body 7 such as a timing belt spanned between the sprockets 6, and the cylinder 8 installed on the endless body 7 are lifted by the extending action to lower the bottom surface of the glass substrate X ( The suction plate 9 sucks the back surface without the film), and after sucking the lower surface of the glass substrate X by the suction cup 9, the endless body 7 is moved to carry the glass substrate X in and out. You may make it achieve the objective by structure.
上記の走行路2内で往復走行する第1カッタ3は、図2に示すように、モーター10により可逆駆動する定位置での軸承雄ネジ11と、ガイドレール12により不回転状態にして雄ネジ11にねじ込む雌ネジ13と、この雌ネジ13の上面に据え付けたシリンダ14の伸長作用により上昇してガラス基板Xの下面に第1カッタ3を押し付けると共に、押し付け状態を維持しながらモーター10の正転運転により雄ネジ11をドライブしながら、雌ネジ13を前進させながら第1切断線4を入れるようにしてある。   As shown in FIG. 2, the first cutter 3 that reciprocates in the traveling path 2 has a male screw 11 in a non-rotating state with a bearing male screw 11 at a fixed position that is reversibly driven by a motor 10 and a guide rail 12. 11 and the cylinder 14 installed on the upper surface of the female screw 13 is lifted by the extending action to press the first cutter 3 against the lower surface of the glass substrate X, and the motor 10 is adjusted while maintaining the pressed state. While driving the male screw 11 by rolling operation, the first cutting line 4 is inserted while the female screw 13 is advanced.
上記の走行路2、5は、図示の場合並列四枚のテーブルを並べて、センターに第1カッタ3用の一本の走行路2を、両サイドに吸盤9用の計二本の走行路5を設けたが、並列間隙にかえて第1テーブルAに上下面が開放する長孔を設けて、この長孔内で第1カッタ3、吸盤9を走行させてもよい。   In the illustrated case, the traveling paths 2 and 5 are arranged in parallel with four tables, one traveling path 2 for the first cutter 3 at the center and two traveling paths 5 for the suction cups 9 on both sides. However, instead of the parallel gap, a long hole whose upper and lower surfaces are opened may be provided in the first table A, and the first cutter 3 and the suction cup 9 may be run in the long hole.
なお、ガラス基板Xの下面に第1切断線4を入れる要因は、液晶パネルなどのガラス基板Xの上面(表面)に膜(電極パターンなどの)が設けてあることによる。   The reason for putting the first cutting line 4 on the lower surface of the glass substrate X is that a film (such as an electrode pattern) is provided on the upper surface (front surface) of the glass substrate X such as a liquid crystal panel.
また、第1テーブルAの搬出端両側部にシリンダ15の伸長作用により上方に突出させるストッパ16を設けて、このストッパ16にガラス基板Xの搬入方向辺縁を当接させて、搬入したガラス基板Xの停止位置決めを行なうようにしてある。   In addition, a stopper 16 is provided on both sides of the carry-out end of the first table A so as to protrude upward by the extension action of the cylinder 15, and the glass substrate X carried in is brought into contact with the stopper 16 at the edge in the carry-in direction of the glass substrate X. X stop positioning is performed.
そして、周知のように(図示のように)、両ストッパ16の手前上方にカメラ17、17を配置して、カメラ17、17によりガラス基板Xの搬入先行辺の両角の印(図示省略)を読み取って第1切断線4を入れる正確な位置決めを、第1テーブルAの下面中心の旋回軸18の時計、反時計方向の駆動により修正するように(第1のテーブルAの旋回にかえて、第1カッタ3の走行ラインを変更してもよい)なっている。   Then, as is well known (as shown), the cameras 17 and 17 are arranged in front of the stoppers 16 and both corners (not shown) of the leading edge of the glass substrate X are introduced by the cameras 17 and 17. Correct positioning by reading and inserting the first cutting line 4 is corrected by driving the pivot shaft 18 at the center of the lower surface of the first table A in the clockwise and counterclockwise directions (instead of pivoting the first table A, The travel line of the first cutter 3 may be changed).
さらに、図示のように、第1テーブルAを中空のボックスとし、かつ頂壁に小孔19群を設けてボックス内の吸引により第1テーブルAにガラス基板Xを吸引保持する。   Further, as shown in the figure, the first table A is a hollow box, and a small hole 19 group is provided on the top wall, and the glass substrate X is sucked and held on the first table A by suction in the box.
すると、切断線を入れる加工時のガラス基板Aの移動をなくすることができる。   Then, the movement of the glass substrate A at the time of the process which puts a cutting line can be eliminated.
また、第1テーブルAの前方に第2テーブルBを設けると共に、この第1テーブルAと第2テーブルBとの間には、第1テーブルA上から第2テーブルB上に所定の長さ搬出され、搬出停止後のガラス基板Xの下面に第1切断線4に対し直角に交差する第2切断線21を入れる往復走行の第2カッタ22が設けてある。   In addition, a second table B is provided in front of the first table A, and a predetermined length is carried out from the first table A to the second table B between the first table A and the second table B. In addition, a second cutter 22 for reciprocating is provided on the lower surface of the glass substrate X after the carry-out is stopped, and a second cutting line 21 that intersects the first cutting line 4 at a right angle.
上記第2カッタ22の往復走行の構成は、第1カッタ3の往復走行の構成と同様につき説明を省略する。   The configuration of the reciprocating travel of the second cutter 22 is the same as that of the reciprocating travel of the first cutter 3, and the description thereof is omitted.
さらに、第2カッタ22の走行ラインの上側には、ガラス基板Xの第2切断線21上に応力を加えて第2切断線21の部分を分断する第1分断手段23が設けてある。   Further, on the upper side of the travel line of the second cutter 22, first dividing means 23 is provided for applying stress on the second cutting line 21 of the glass substrate X to divide the portion of the second cutting line 21.
上記の第1分断手段23は、図2、4、5に示すように、ガイド軸24によりガイドされて昇降する水平な折割バー材25と、この折割バー材25を昇降するシリンダ26とで構成され、シリンダ26の伸長作用によって降送する折割バー材25をガラス基板Xの上面第2切断線21の直上に押し付けながら応力を加えて第2切断線21を分断する。   As shown in FIGS. 2, 4, and 5, the first dividing means 23 includes a horizontal folding bar member 25 that is guided by a guide shaft 24 and moves up and down, and a cylinder 26 that lifts and lowers the folding bar member 25. The second cutting line 21 is divided by applying stress while pressing the folding bar member 25 that is lowered by the extending action of the cylinder 26 directly above the upper surface second cutting line 21 of the glass substrate X.
すると、ガラス基板Xから大割ガラス基板Yを分割する。   Then, the large glass substrate Y is divided from the glass substrate X.
上記の分断された第2テーブルB上の大割ガラス基板Yは、第2テーブルBの第1テーブルA側辺縁から前途中迄の前半第2搬送手段Eによって搬出されて荷受けすると共に、荷受後に90度の旋回手段31に旋回させる。   The large glass substrate Y on the divided second table B is unloaded and received by the first half second conveying means E from the first table A side edge of the second table B to the front halfway. Later, the turning means 31 is turned 90 degrees.
上記の旋回手段31は、図1、6に示すように、第2テーブルBの中間中央にモーター32の運転により90度回転し、かつシリンダ33の作用により昇降する回転軸34の上端旋回座35の上面に吸盤36を設けて構成し、旋回座35の直上に大割ガラス基板Yが搬入されると、シリンダ33の伸長作用により旋回座35を上昇させて大割ガラス基板Yの下面に吸盤36を当接し、次いでモーター32の運転により回転軸34を90度回転させて、大割ガラス基板Yを旋回する。   As shown in FIGS. 1 and 6, the turning means 31 is rotated 90 degrees by the operation of the motor 32 in the middle center of the second table B and is moved upward and downward by the action of the cylinder 33, and the upper turning seat 35 of the rotating shaft 34. The suction glass 36 is provided on the upper surface of the glass substrate Y. When the large glass substrate Y is loaded immediately above the swivel seat 35, the swivel seat 35 is raised by the extension action of the cylinder 33, and the suction glass is placed on the lower surface of the large glass substrate Y. Then, the rotary shaft 34 is rotated 90 degrees by the operation of the motor 32, and the large glass substrate Y is turned.
しかして、旋回後にシリンダ33の収縮作用により回転軸34と共に大割ガラス基板Yを降下させて、第2テーブルBの途中から前方の第3テーブルCに向け後半第2搬送手段E′に荷受け後搬出する。
Thus, after turning, the large glass substrate Y is lowered together with the rotating shaft 34 by the contraction action of the cylinder 33, and is received by the second-half second transport means E ′ from the middle of the second table B toward the third table C ahead. Take it out.
上記の前半搬送手段E及び後半搬送手段E′は、第1搬送手段Dと同形式を採用のため構成の説明を省略する。   The above-mentioned first half transport means E and second half transport means E ′ adopt the same format as the first transport means D, and the description of the configuration is omitted.
そして、第1分断手段23により分断された大割ガラス基板Yを、前半搬送手段Eのシリンダ8の伸長作用により上昇する吸盤9により荷受けして搬送し、旋回座35の直上に大割ガラス基板Yが到着すると、シリンダ33の伸長作用により旋回座35を上昇させて、大割ガラス基板Yの下面に吸盤36を当接させて吸引する。   Then, the large glass substrate Y divided by the first dividing means 23 is received and conveyed by the suction cup 9 which is lifted by the extension action of the cylinder 8 of the first half conveying means E, and is conveyed immediately above the swivel seat 35. When Y arrives, the swivel seat 35 is raised by the extension action of the cylinder 33, and the suction cup 36 is brought into contact with the lower surface of the large glass substrate Y for suction.
上記の吸引後に、吸盤9による吸引を解除し、次いでシリンダ8の収縮作用により吸盤9を降下後、旋回の動作を行なう。   After the above suction, the suction by the suction cup 9 is released, and then the suction cup 9 is lowered by the contracting action of the cylinder 8, and then the turning operation is performed.
旋回後に、後半搬送手段E′の吸盤9をシリンダ8の伸長作用により上昇させて、吸引した吸盤9に大割ガラス基板Yを荷受けしたのち、シリンダ33の収縮作用によって吸盤36を降下する。   After the turn, the suction cup 9 of the second half transport means E ′ is raised by the extension action of the cylinder 8 and the large glass substrate Y is received by the sucked suction cup 9, and then the suction cup 36 is lowered by the contraction action of the cylinder 33.
しかして、後半搬送手段E′によって大割ガラス基板Yを搬出するようになっている。   Accordingly, the large glass substrate Y is unloaded by the latter half transport means E ′.
そして、第2テーブルBと第3テーブルCとの間に大割ガラス基板Yの第1切断線4が到着すると、第1切断線4の直上に設けてある第2分断手段41により大割ガラス基板Yの上面第1切断線4の部分に応力を作用させる。   And when the 1st cutting line 4 of the large glass substrate Y arrives between the 2nd table B and the 3rd table C, the large glass is carried out by the 2nd dividing means 41 provided immediately above the 1st cutting line 4. Stress is applied to the portion of the upper surface first cutting line 4 of the substrate Y.
この応力の作用により大割ガラス基板Yを分断して、製品サイズの小割ガラス基板Zを得る。   The large glass substrate Y is divided by the action of the stress to obtain a small glass substrate Z having a product size.
上記の第2分断手段41は、第1分断手段23と同様につき構成並びに作用の説明を省略する。   Since the second dividing means 41 is the same as the first dividing means 23, the description of the configuration and operation is omitted.
また、第3テーブルCを第1搬送手段Dや第2搬送手段E、E′と同様の第3搬送手段Fを設けて、小割ガラス基板Zを取り下ろすようにしたが、その他の手段で取り下ろすこともある。   Further, the third table C is provided with the third transport means F similar to the first transport means D and the second transport means E and E ′, and the small glass substrate Z is taken down, but other means are used. May be withdrawn.
なお、第2テーブルB及び第3テーブルCを第1テーブルAと同様に小孔19群を設けて、エアーの噴出によりスムーズな搬送を行なうようにしてもよい。   The second table B and the third table C may be provided with a group of small holes 19 similarly to the first table A so as to perform smooth conveyance by blowing air.
次に前述の構成に基づいて図9の切断、分断工程図により切断、分断方法を説明する。   Next, based on the above-described configuration, the cutting and dividing method will be described with reference to the cutting and dividing process diagram of FIG.
