施試驗塗佈’因此，必須另外設置試驗塗佈面。 又’當透過目視而實施對準位置時’該位置會因作業者而 ❹有偏差，其精確度也有界限。且，該作業複雜又花費時間。 因此，本發明之目的為提供一種不必使用攝影機或感測器 等之特殊的機器，可以簡單之構成而機械地實施位置調整之 喷嘴位置修正機構及具備該機構之塗佈裝置。 (解決問題之手段） 第1發明係，藉由驅動機構使吐出液體材料之噴嘴與載置

在短時間内實施噴嘴位置調整’且不需要塗佈作業開始位置 等之設定修正。 【實施方式】 以下說明本發明之一實施形態。 (定位構件） 參 參 圖1表示本發明之定位構件仙的概略斜視®，圖2表示 前視圖。圖i及圖2之構成例中，定位構件1〇h系由搬合構 件1〇2與抵接構件103之2個構件所構成。嵌合構件ι〇2 係大致呈直方體形狀，吐出裝置7〇5具有之喷嘴7〇7的前端 部份被插通的孔1〇4自上面向下面貫通而被設置。 孔104被形成比喷嘴707稍為大徑，具有可修正喷嘴術 的偏差之充份的深度（例如，噴嘴的長度之1/3〜丨^。 孔104 ’在噴嘴進入侧的緣部設有推拔部ι〇5。換士之，孔 1〇4的入口部份係圓錐台狀’自圓錐台之前端一二口部 份成為圓筒狀。如此藉由設置推拔部⑽，_ 構3〇1而使喷嘴707前端部份嵌合於孔ΠΜ時，則可更容易 插入喷嘴707。又’嵌合構件⑽ Z更-易 脹或收縮)優越的塑膠材料(例 ^質(特別是膨 田或# ( j如聚醚醚酮）構成較佳。苴 因為，第一，可藉由抑制因 八 置修正的誤差減低為最錢收縮所發生顿嘴嘴位 在孔104中插入喷嘴7()7時 1金屬材料構成時， 」有谷易抽傷喷嘴707之虞。只 098125811 201012549 要可達成此等目的’則以塑膠材料僅構成定位構件ι〇ι的一 部份（例如’只有嵌合構件1〇2)亦可。 又’孔104之形狀只要配合喷嘴707的形狀而形成即可， 其並不被限定於圓筒狀。 抵接構件103，係在中央具有凹陷部1〇8之凹形狀在此 凹陷部108的底面，構成和喷嘴7〇7前端部份的吐出口所形 成之面相接觸之抵接面106。藉由在抵接構件1〇3與嵌合構 件102之間開設間隙而設置抵接面1〇6，則在利用後述調整 機構301嵌合喷嘴7〇7而使噴嘴前端接觸抵接面時，則其可 藉由目視而予以確認（具有窗口的作用）。圖i及圖2之構成 例中，上述2個構件（1〇2、1〇3)係以螺絲1〇7等的繫緊構件 而被固定以構成定位構件1〇1。當藉由以個別構件而構成嵌 合構件102與抵接構件1〇3時，在孔1〇4的内侧或外侧的緣 部等如附著液體材料之情形，或要變更喷嘴7〇7的口徑之情 形，則不必卸下定位構件101全體而只要卸下嵌合構件1〇2 即可實施清掃或和其他零件作交換。 又，如上述2個構件（1〇2、103)不以個別構件構成時亦 可’而噴嘴707的嵌合之孔1〇4或喷嘴前端所抵接之抵接面 106以1個構件設成亦可。又，凹陷部108並不是必須的構 成’如不設置亦可。 定位構件101，係相對於驅動機構（702、703、704)的基 準位置（例如，原點等）被相對配設於所規定的位置（自基準 098125811 8 201012549 位置起被指定之座標位置）。例如，定位構件ι〇ι，雖然被 配設於和作業台710上的塗佈對象物·不重疊之位置，但 只要是設在嘴嘴707的可動範圍内即可。由於定位構件ι〇ι 被固定設在特定的位置，因此，只要藉定位構件ι〇ι而實施 喷嘴707的位置調㈣，即可對記憶在控制部的位置（座標） 使喷嘴707的位置對準。如此，由於被位置調整之喷嘴μ? 與工件上之塗佈位置的關係係和記憶在控制部的位置（座標） ® —致，因此，其亦不需要塗佈開始位置之特定作業。 又，在定位構件1〇1之嵌合構件1〇2，藉由對工件面設置 和垂直的直線平行之比較深（長）的直線狀之孔時，在替換喷 嘴707時則可修正喷嘴中心轴自前述垂直直線之偏差（傾斜 等）。在本發明中，於噴嘴707之前端部份接觸抵接構件1〇3 的抵接面之位置而調整喷嘴707時，由於前述喷嘴γογ的前 端部份之Z軸方向的位置（自基準面之高度）經常相同，因 ❿此’其不需變更為了在工件上塗佈時所必要間隙（c丨earance ) 之設定。因此，其可容易對應於喷嘴7〇7的種類或製造誤差 所致之噴嘴前端部份形狀等之偏差。 如此’藉由使用本發明之定位構件1〇1，噴嘴？〇7之塗佈 位置或和工件間隙之設定不必以自動或手動地變更，即可簡 單地使位置對準。 (調整機構） 圖3表示本發明之調整機構301的概略斜視圖，圖4表示 098125811 9 201012549 其三面圖。在圖4中，（a)表示前視圖，（b)表示俯視圖， (c)表示左側視圖。此處，X、γ、z麵各方向之座標轴的 方向在圖3中以符號302表示。 如圖3所示’調整機構301被設在：吐出裝置705(以虛 線圖示）；以及，被安裝在Z軸驅動機構7〇4(以虛線圖示）之 連接構件303之間。又，調整機構3〇1係由：X方向調整部 304、Y方向調整部305、及Z方向調整部306所構成，各調 整部（304、305、306)係由各別的滑動導件（3〇7、308、309) 及滑動構件（310、311、312)所構成。各滑動導件（ 307、 308、309)被安裝成如圖3箭頭所示朝各方向可使各滑動構 件（310、311、312)移動，由此’其可使吐出裝置705朝 向XYZ之各方向移動。 又，在各調整部（304、305、306)被安裝有為了在任意 的位置固定各調整部用之夾緊板（313、314、315)與夾緊 螺絲（316、317、318)。夾緊板（313)被設成橫跨滑動構 件與連接構件間’而夾緊板（314、315)被設在橫跨二個滑 動構件間。夾緊板（313、314、315) —邊以固定螺絲319被 固定’另一邊以夾緊螺絲（316、3Π、318)所固定。在夾緊 板（313、314、315)的夾緊螺絲（316、317、318)側，其開 設有對應於移動方向之長圓孔32〇。夾緊螺絲（316、317、 318)係由大徑的手抓部份與細徑的螺紋部份所構成，而該 螺紋部份’對該孔320的寬度具有微小之間隙而被插通於 098125811 201012549 孔，該螺紋部份的前端被螺入至滑動構件或連接構件。 以下對Z方向調整部306舉例如下說明夾緊板（313、314、 315)及夾緊螺絲（316、317、318)的作用。如鬆脫z夾緊螺 絲318時，在Z夾緊螺絲318之手抓部份與Y滑動構件311 間夾住Z夾緊板315的力量會鬆弛，而固定螺絲319側的z 滑動構件312則變成可移動。相反地，鎖緊z夾緊螺絲318 時，Z夾緊板315被夾在z夾緊螺絲318的手抓部份與γ滑 ❹動構件311之間而其動作被限制，而z滑動構件312被固 疋。Z滑動構件312於Z夾緊板315所開設的長圓孔320之 長度的範圍内成為可移動。 (修正次序） 以下說明使用上述定位構件1〇1及調整機構3〇1之喷嘴 707的位置之修正次序。又，以下為了說明方便起見，雖然 附有符唬，但其並不限定和符號相對應之圖面構成的次序。 圖5表示本發明之第一修正次序的流程圖。 首先’在塗佈裝置7〇1的驅動機構（ 702、703、704)藉 由5周整機構301而安襞具有喷嘴之吐出裝置705(步驟11)。 此處’以調整機構3〇1將噴嘴7〇7朝z方向向上方移動（步 驟12)。适是為了使在次一步驟移動喷嘴7〇7時，不會使喷 嘴707之前端碰觸到定位構件1〇1者。其次，湘驅動機構 (702、703、704)朝預先所設定之定位構件1〇1的位置（χγζ 定位位置）移動喷嘴步驟⑶。又，為了使定位位置在 098125811 11 201012549 一旦設定後即不會變更，使用調整機構3〇1來實施喷嘴707 之位置調整.變更（步驟14〜15)。喷嘴7〇7移動至定位構 件ι〇1的上方時，首先，利用X及γ方向之調整部304、305 微調整喷嘴707前端的位置而使喷嘴707前端料嵌合構件 之孔104的位置。當此定位完了後，鎖緊夹緊螺絲316、317 而固定X及Y方向調整部（步驟⑷。其次，利用z方向調 整部306朝嵌合構件之孔1〇4插入喷嘴7〇7，使喷嘴前 端下降抵觸至抵接面106。此時，以目視一面確認噴嘴7〇7 的前端另—面實施即可。在抵觸位置鎖緊夹緊螺絲318而固 定z方向調整部306(步驟15)。自嵌合構件之孔1〇4抽出喷 嘴707而開始塗佈作業（步驟16)。 又，其他的方法中，亦可以如次所示之次序來實施喷嘴 707之位置調整。 圖6表示本發明之第二修正次序的流程圖。 首先’在塗佈裝置701的驅動機構（7〇2、703、704)藉 由調整機構301而安裝具有喷嘴707之吐出裝置705 (步驟 21 )。其次，利用驅動機構（7〇2、703)對預先所設定之χγζ 疋位位置中除了 Ζ位置對X及γ位置使噴嘴7〇7移動（步驟 22)。當喷嘴移動至定位構件ιοί的上方時，利用X及γ方 向之調整部304、305微調整喷嘴707前端的位置使喷嘴 之前端位置對準嵌合構件之孔104的位置。在此定位完了 後’鎖緊夾緊螺絲316、317而固定X及γ方向調整部（步驟 098125811 12 201012549 23)。其次，利用驅動機構（704)僅對預先所設定之χγζ定位 位置中之向ζ位置之移動實施至途中（步驟24)。在步驟24 中利用Ζ方向調整部306使插入至嵌合構件的孔1〇4之喷嘴 707下降到喷嘴707前端抵觸至抵接面ι〇6。此時，以目視 一面確認喷嘴707的前端另一面實施即可。在抵觸位置鎖緊 夾緊螺絲318而固定Ζ方向調整部（步驟25)。自嵌合構件 之孔104抽出喷嘴707而開始塗佈作業（步驟26)。 ❹ 以上，雖然例示二種次序，但只要利用定位構件ιοί與調 整機構301，則並不受限於上述二種次序，其如藉其他之次 序實施亦可。 以下雖然藉實施例而詳細說明本發明，但本發明並不受限 於任一實施例。 [實施例1] (塗佈裝置） 如圖7所示，本實施例之塗佈裝置7〇1具有：χ驅動機構 702 ’及’ Υ驅動機構703 ;及，Ζ驅動機構704 ;及，吐出 裝置705 ;及控制此等動作之控制部709。 在X驅動機構702設置Ζ驅動機構704。在Υ驅動機構703 上设置可载置塗佈對象物708之作業台710。吐出裝置705 具備·可貯存液體材料之貯存容H 7G6 ;及，在其前端可吐 出液體材料之嗔嘴術。雖然吐出裝置705以貯存容器7〇6 和喷嘴7〇7 + Λ 、、且合來表不’但其並不受限於此，其只要且有 098125811 13 201012549 喷嘴707者即可。 調整機構301被配δ又在Z驅動機構7〇4與吐出裝置7〇5 之間。此時，調整機構301、4驅動機構704及吐出裝置 705不在Υ方向串聯安裝’而吐出裝置7{)5係被配置在調整 機構3(Π的X方向之部位（例如滑動構件312)為佳。由此， 則可容易對調整機構301操作。又，當使吐出裝置配設 於調整機構则之X方向時，自X軸驅動機構的距離則 變短’其比將吐出裝置705及調整機構謝串聯配設在γ 方向之情形可使Z軸驅動裝置704 f曲而使負荷減低。 定位構件101被配設在和作業台71〇上之塗佈對象物7〇8 不重疊的位置。本實施例中，雖然使定位構件1〇1設在作業 台710上，但其並不一定要設在作業台71〇上，只要設在喷 嘴707之可動範圍内即可。又，當設在作業台71〇上時則 使抵接構件103和作業台710 —體設置，而僅使嵌合構件 102可裝却’如此亦可。不管任一設置方法，其定位構件1 〇 1 對驅動機構（ 702、703、704)之基準位置（例如原點等）均 被配設在相對的規定位置（自基準位置被指定之座標位 置）。為了確保交換等時之安裝位置的再現性，如使安裂面 岗準確度地加工或者設置未圖示之定位銷，如此為佳。 在塗佈作業時，首先，在塗佈裝置701設置所準備之吐出 裝置705。其後，以前述方法調整喷嘴707的位置。又，使 塗佈對象物708栽置固定於作業台710上。其次，向嘴嘴 098125811 14 201012549 707下方移動，而開始塗佈作業。當塗佈終了時，作業台7i〇 及吐出裝置705藉由各驅動機構（7〇2、703、704)朝向等待 位置移動，而使對一個塗佈對象物7〇8之塗佈作業終了。要 對複數個塗佈對象物708繼續塗佈作業時，則將已塗佈之塗 佈對象物708和未塗佈之塗佈對象物7〇8交換而反覆上述作 業。又，如要實施補充液體材料或交換喷嘴7〇7之作業則將 吐出裝置705卸下或安裝，而實施前述之喷嘴位置調整，並 ❹重新開始上述作業。 [實施例2] (在定位構件設置複數個孔之構成例） 在實施例1中，雖然定位構件1〇1的喷嘴嵌合之孔1〇4 只有1個，但為了對應於假設使用複數種類的喷嘴直徑亦 可設置複數個不同内徑的孔（8〇5〜8〇9)。圖8表示該構成 例。 φ 圖8所表示之定位構件801，係和實施例丨同樣由嵌合構 件802與抵接構件803之2個構件所構成。在嵌合構件8〇2 上於其中央設置最常使用之喷嘴嵌合之孔8〇5。又，在其右 侧設置比中央的孔805更大徑之孔（8〇6、807)，而在左侧則 設置比中央的孔805更小徑之孔（808、809)。在各別的孔 (805〜809)中配合孔之直徑被設置和前述相同的推拔部 810。如此藉由預先設置複數種類的孔（8〇5〜8〇9)時則不 必交換定位構件801即可對應於液體材料之變更或變更所 098125811 15 201012549 希望之塗佈量。又，如預先決定所使用之噴嘴直徑，則只要 設置該噴嘴嵌合的孔即可。被形成於抵接構件8〇3之抵接面 804係對應於孔（805〜809)的個數所形成者。 (產業上之可利用性） 本發明在藉由喷嘴吐出液體材料之各種裝置中可被實施。 除了實施例所列舉之在前端具有喷嘴之貯存容器内的液

Description of the Invention: [Technical Leadership of the Invention] The present invention relates to a nozzle position correcting mechanism and a coating device having the same. More specifically, the liquid material is discharged by the '_ mechanism Nozzle > When the liquid material is applied to the workpiece surface while moving relative to the workpiece placed on the work table, the nozzle positive mechanism for correcting the nozzle position deviation can be corrected in accordance with the maintenance work. > © [Prior Art] When performing work such as replenishment or maintenance of liquid material > Remove the discharge device including the nozzle or the storage container. Further, when the operation of the coating device or the maintenance is completed, the dispensing device is attached to the tip end of the nozzle, and is formed at the tip end of the nozzle having the discharge device. Coating device. This will deviate from the position before removal. When the state of the sputum is reopened and the ϋ state is re-opened, the liquid material 纴13 is applied to the position where the coating is not applied, and the product is coated with the working material, which is a defective product. Therefore, as a result, there are various proposals for the liquid to be coated, and it is recommended to adjust the nozzle when the discharge device is installed, and to avoid the above-mentioned situation or method. For example, in Patent Document 1, a night body is coated on a substrate surface, and a nozzle having a coating device mounted on a liquid material and discharging a liquid material toward the substrate surface is disclosed. The ejector photographs the nozzle, and the positional deviation of the nozzle from the machine side and the vertical line from the front end of the nozzle is detected from the photographic image. The height of the detector is η 098125811 201012549 according to the position detector The controller in which the positional deviation of the injection|| is performed by the height position and the position deviation amount mentioned above; Further, Patent Document 2 discloses a method of detecting the position of the (four) in a coating device having a coating nozzle and an image forming apparatus, and is characterized in that a coating agent is applied to a test coating surface by a coating nozzle. At the same time, the second position at the position of the photographing h of the photographing device is obtained. Next, the center position of the coating agent and the photographing device are obtained by photographing the coating agent applied to the test coated surface by the photographing device. In the second position of the photographing center, the difference between the X-axis direction and the ¥axis direction of the first position and the second position is obtained, and the relative position of the imaging device of the application nozzle is indicated. A method of detecting the relative position of a coating nozzle. The position detecting device used in Patent Document 1 or 2 is a camera, but other optical devices such as a 'laser displacement meter or a photo sensor may be used. However, there are still people who are tired of having to set up such a special machine, but still operate the XYZ drive mechanism equipped with the discharge device by hand, and visually align the target position such as the application position to move the nozzle end' and from the difference between the movement amounts Correct the settings such as the start position of the coating operation. Patent Document 1: Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. 2 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In the inventions described in 1 and 2, it is necessary to use a special machine such as a camera or a sensor for detecting the position, and the calculation processing or control based on the detection result is also quite complicated. Further, in the invention described in Patent Document 2, it is necessary to perform test coating in order to detect the position. Therefore, it is necessary to separately provide a test coated surface.

[Embodiment] An embodiment of the present invention will be described below. (Positioning member) Reference Fig. 1 shows a schematic squint® of the positioning member of the present invention, and Fig. 2 shows a front view. In the configuration example of Fig. 1 and Fig. 2, the positioning member 1〇h is composed of two members of the carrying member 1〇2 and the abutting member 103. The fitting member ι 2 has a substantially rectangular parallelepiped shape, and the tip end portion of the nozzle 7〇7 of the discharge device 7〇5 is inserted through the hole 1〇4 which is inserted from the upper surface to the lower surface. The hole 104 is formed to have a slightly larger diameter than the nozzle 707, and has a sufficient depth to correct the deviation of the nozzle (for example, 1/3 to 长度 of the length of the nozzle. The hole 104' is provided at the edge of the nozzle entry side. Pull the 〇 〇 。 。 。 。 换 换 换 换 换 换 换 换 换 换 换 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 换 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 When the front end portion of the nozzle 707 is fitted into the hole 〇1, the nozzle 707 can be inserted more easily. Further, the 'fitting member (10) Z is more swellable or contracted) superior plastic material (except for the expansion) Field or # (j such as polyetheretherketone) is preferred. Because, first, the nozzle 7 can be inserted into the hole 104 by suppressing the error due to the eight-set correction to the most contraction. When 7:1 metal material is formed, "there is a gluten-free nozzle 707. Only 098125811 201012549 can achieve such a goal." The member 1〇2) may be combined. The shape of the hole 104 may be formed by matching the shape of the nozzle 707, and The abutting member 103 has a concave shape having a depressed portion 1〇8 at the center, and a bottom surface of the depressed portion 108 is formed to be in contact with a surface formed by the discharge port of the front end portion of the nozzle 7〇7. When the contact surface 106 is provided with a gap between the contact member 1〇3 and the fitting member 102, the nozzle 7〇 is fitted to the nozzle 7〇7 by the adjustment mechanism 301 described later. When the surface is abutted, it can be confirmed by visual observation (having the function of a window). In the configuration example of Fig. i and Fig. 2, the above two members (1〇2, 1〇3) are screwed 1〇7 The fastening member is fixed to constitute the positioning member 1〇1. When the fitting member 102 and the abutting member 1〇3 are configured by individual members, the inner or outer edge of the hole 1〇4 is equal to or the like. When the liquid material is attached or the diameter of the nozzle 7〇7 is to be changed, it is not necessary to remove the entire positioning member 101, and the cleaning member or the other parts can be exchanged by removing the fitting member 1〇2. If the two members (1〇2, 103) are not formed by individual members, the nozzle 707 can be embedded. The hole 1〇4 or the abutting surface 106 to which the tip end of the nozzle abuts may be provided by one member. Further, the recessed portion 108 is not necessarily required to be configured. The positioning member 101 may be opposed to The reference position (for example, the origin) of the drive mechanism (702, 703, 704) is relatively disposed at a predetermined position (a coordinate position designated from the position of 098125811 8 201012549). For example, the positioning member ι〇ι Although it is disposed at a position that does not overlap with the application object on the work table 710, it may be provided within the movable range of the mouth 707. Since the positioning member ι〇 is fixed at a specific position Therefore, by performing the position adjustment (4) of the nozzle 707 by the positioning member ι〇, the position of the nozzle 707 can be aligned with the position (coordinate) stored in the control unit. Thus, since the position-adjusted nozzle μ? is related to the coating position on the workpiece and the position (coordinate) stored in the control portion, it does not require a specific operation of the coating start position. Further, in the fitting member 1〇2 of the positioning member 1〇1, when the workpiece surface is provided with a relatively deep (long) linear hole parallel to the vertical line, the nozzle center can be corrected when the nozzle 707 is replaced. The deviation of the axis from the aforementioned vertical line (tilt, etc.). In the present invention, when the nozzle 707 is adjusted by the position of the front end portion of the nozzle 707 contacting the abutting surface of the abutting member 1〇3, the position of the front end portion of the nozzle γογ in the Z-axis direction (from the reference surface) The height is often the same, because it does not need to change the setting of the necessary clearance (c丨earance) for coating on the workpiece. Therefore, it can easily correspond to the variation of the shape of the nozzle 7〇7 or the shape of the tip end portion of the nozzle due to manufacturing errors. So by using the positioning member 1〇1 of the present invention, the nozzle? The setting of the coating position of the crucible 7 or the gap with the workpiece does not have to be changed automatically or manually, so that the position can be simply aligned. (Adjustment Mechanism) Fig. 3 is a schematic perspective view showing an adjustment mechanism 301 of the present invention, and Fig. 4 is a three-side view of 098125811 9 201012549. In Fig. 4, (a) shows a front view, (b) shows a plan view, and (c) shows a left side view. Here, the direction of the coordinate axis in each of the X, γ, and z faces is indicated by reference numeral 302 in Fig. 3 . As shown in Fig. 3, the adjustment mechanism 301 is provided between the discharge device 705 (shown by a broken line) and the connection member 303 of the Z-axis drive mechanism 7〇4 (shown by a broken line). Further, the adjustment mechanism 3〇1 is composed of an X-direction adjustment unit 304, a Y-direction adjustment unit 305, and a Z-direction adjustment unit 306, and each adjustment unit (304, 305, 306) is composed of a separate slide guide ( 3〇7, 308, 309) and sliding members (310, 311, 312). Each of the sliding guides (307, 308, 309) is mounted to move the sliding members (310, 311, 312) in various directions as indicated by the arrows in Fig. 3, thereby allowing the ejection device 705 to face each of the XYZ Move in direction. Further, clamp plates (313, 314, 315) and clamp screws (316, 317, 318) for fixing the respective adjustment portions at arbitrary positions are attached to the respective adjustment portions (304, 305, 306). A clamping plate (313) is provided across the sliding member and the connecting member' and the clamping plates (314, 315) are disposed across the two sliding members. The clamping plates (313, 314, 315) are fixed by the fixing screws 319 and the other side is fixed by the clamping screws (316, 3, 318). On the side of the clamping screw (316, 317, 318) of the clamping plate (313, 314, 315), it is provided with an oblong hole 32 对应 corresponding to the moving direction. The clamping screws (316, 317, 318) are formed by a large-diameter grip portion and a threaded portion of a small diameter, and the threaded portion 'with a slight gap in the width of the hole 320 is inserted into 098125811 201012549 Hole, the front end of the threaded portion is screwed into the sliding member or the connecting member. Hereinafter, the action of the clamp plates (313, 314, 315) and the clamp screws (316, 317, 318) will be described below with respect to the Z-direction adjustment portion 306. When the z-clamping screw 318 is loosened, the force of clamping the Z-clamping plate 315 between the grip portion of the Z-clamping screw 318 and the Y-sliding member 311 is relaxed, and the z-sliding member 312 on the side of the fixing screw 319 is Becomes movable. Conversely, when the z-clamping screw 318 is locked, the Z-clamping plate 315 is sandwiched between the grip portion of the z-clamping screw 318 and the gamma sliding and sliding member 311, and its action is restricted, and the z-sliding member 312 is restrained. Be fixed. The Z sliding member 312 is movable within the range of the length of the oblong hole 320 formed by the Z clamping plate 315. (Revisional order) The correction procedure of the position of the nozzle 707 using the above-described positioning member 1〇1 and adjustment mechanism 3〇1 will be described below. Further, in the following, for convenience of explanation, although the symbol is attached, it does not limit the order of the drawings corresponding to the symbols. Figure 5 is a flow chart showing the first modification sequence of the present invention. First, the drive mechanism (702, 703, 704) of the coating device 7〇1 is used to mount the discharge device 705 having the nozzle by the five-week mechanism 301 (step 11). Here, the nozzle 7〇7 is moved upward in the z direction by the adjustment mechanism 3〇1 (step 12). It is desirable that when the nozzle 7〇7 is moved in the next step, the front end of the nozzle 707 is not touched to the positioning member 1〇1. Next, the Xiang drive mechanism (702, 703, 704) moves the nozzle step (3) toward the position (χγζ positioning position) of the positioning member 1〇1 set in advance. Further, in order to make the positioning position not change after setting 098125811 11 201012549, the position adjustment and change of the nozzle 707 are performed using the adjustment mechanism 3〇1 (steps 14 to 15). When the nozzle 7〇7 is moved above the positioning member ι〇1, first, the position of the tip end of the nozzle 707 is finely adjusted by the adjustment portions 304 and 305 in the X and γ directions, and the position of the hole 104 of the tip end of the nozzle 707 is fitted. When the positioning is completed, the clamping screws 316 and 317 are locked to fix the X and Y direction adjusting portions (step (4). Secondly, the z direction adjusting portion 306 is inserted into the holes 1〇4 of the fitting member to insert the nozzles 7〇7. The tip end of the nozzle is lowered against the abutting surface 106. At this time, it is preferable to visually confirm the tip end of the nozzle 7〇7. The clamping screw 318 is locked at the contact position to fix the z-direction adjusting portion 306 (step 15). The nozzle 707 is taken out from the hole 1〇4 of the fitting member to start the coating operation (step 16). Further, in other methods, the position adjustment of the nozzle 707 may be performed in the order shown in the next step. Flowchart of the second modification sequence of the invention. First, the drive mechanism (7〇2, 703, 704) of the coating device 701 is mounted with the discharge device 705 having the nozzle 707 by the adjustment mechanism 301 (step 21). The nozzle 7〇7 is moved by the driving mechanism (7〇2, 703) to the previously set χγζ clamping position except for the Ζ position pair X and γ positions (step 22). When the nozzle moves over the positioning member ιοί, Fine adjustment using the X and γ direction adjustment sections 304, 305 The position of the front end of the nozzle 707 is such that the position of the front end of the nozzle is aligned with the position of the hole 104 of the fitting member. After the positioning is completed, the clamping screws 316 and 317 are locked to fix the X and γ direction adjusting portions (step 098125811 12 201012549 23). Next, the movement mechanism (704) is used only for the movement of the ζ position in the χγζ positioning position set in advance (step 24). In step 24, the Ζ direction adjustment unit 306 is inserted into the fitting member. The nozzle 707 of the hole 1〇4 is lowered until the tip end of the nozzle 707 abuts against the abutting surface 〇6. At this time, it is only necessary to visually confirm the other end of the nozzle 707. The clamping screw 318 is locked at the contact position and fixed. Direction adjustment unit (Step 25): The nozzle 707 is taken out from the hole 104 of the fitting member to start the coating operation (Step 26). ❹ Above, although the two orders are exemplified, the positioning member ιοί and the adjustment mechanism 301 are used. The present invention is not limited to the above two orders, and may be embodied in other orders.
