以上のシート貼付装置10において、被着体WKに接着シートASを貼付する手順について説明する。
先ず、原反RSを図1に示すようにセットする。そして、図示しない操作パネルやパーソナルコンピュータ等の入力手段を介して運転開始の信号を入力すると、保持手段20が充填手段22および排出手段23を駆動し、貯留室27内を所定の圧力(第1圧力)に調整した後、供給手段40が回動モータ44Aを駆動し、原反RSを繰り出す。次いで、剥離板43上に位置する先頭の接着シートASが所定位置に到達したことを光学センサや撮像手段等の図示しない検知手段が検知すると、供給手段40が回動モータ44Aの駆動を停止し、シート貼付装置10がスタンバイ状態となる。
In the above sheet sticking apparatus 10, the procedure for sticking the adhesive sheet AS to the adherend WK will be described.
First, the raw fabric RS is set as shown in FIG. Then, when an operation start signal is input via an input means such as an operation panel (not shown) or a personal computer, the holding means 20 drives the filling means 22 and the discharge means 23, and the storage chamber 27 has a predetermined pressure (first pressure). After the pressure is adjusted, the supply means 40 drives the rotation motor 44A to feed out the original fabric RS. Next, when a detection unit (not shown) such as an optical sensor or an imaging unit detects that the leading adhesive sheet AS positioned on the peeling plate 43 has reached a predetermined position, the supply unit 40 stops driving the rotation motor 44A. The sheet sticking device 10 is in a standby state.
そして、搬送手段CVがコンベア等を駆動し、図1に示すように、被着体WKを保持部材21の下方所定位置で停止させる。次に、供給手段40が回動モータ44Aを駆動し、接着シートASを供給し、保持手段20が静電チャック26を駆動し、供給された接着シートASを保持面25Aで保持する。次いで、押圧手段30が直動モータ31を駆動し、保持部材21を被着体WKに向かって下降させる。そして、接着シートASが被着体WKの被着面WK1に当接すると、図1中二点鎖線で示すように、変形許容部25が変形することにより保持面25Aの変形が許容されて被着面WK1の凹凸に追従し、接着シートAS全体を被着面WK1に押圧して貼付する。この際、接着シートASは、貯留室27内の気体の圧力(第1圧力)によって、全体的に適切で均等な押圧力が付与される。   Then, the conveying means CV drives a conveyor or the like, and stops the adherend WK at a predetermined position below the holding member 21 as shown in FIG. Next, the supply means 40 drives the rotation motor 44A to supply the adhesive sheet AS, the holding means 20 drives the electrostatic chuck 26, and the supplied adhesive sheet AS is held by the holding surface 25A. Next, the pressing means 30 drives the linear motor 31 to lower the holding member 21 toward the adherend WK. When the adhesive sheet AS comes into contact with the adherend surface WK1 of the adherend WK, as shown by the two-dot chain line in FIG. 1, the deformation permitting portion 25 is deformed to allow deformation of the holding surface 25A. Following the unevenness of the wearing surface WK1, the entire adhesive sheet AS is pressed and stuck to the wearing surface WK1. At this time, the adhesive sheet AS is given an appropriate and uniform pressing force as a whole by the pressure of the gas in the storage chamber 27 (first pressure).
ここで、貯留室27内の圧力を検出する圧力センサやロードセル等の図示しない検知手段を設け、当該検知手段の検知結果を基にして保持手段20が排出手段23を駆動し、貯留室27内の圧力(第1圧力)を保った状態で気体を徐々に排出するように構成してもよい。このとき、押圧手段30が直動モータ31を駆動し、保持部材21を下降させることができる。これにより、保持面25Aの変形を促進させることができ、被着面WK1の凹凸が大きい場合でも、当該凹凸に保持面25Aを追従させることができ、被着面WK1に接着シートASを密着させることができる。また、貯留室27内の圧力を保った状態で、気体を徐々に排出して被着面WK1に接着シートASを密着させた後、保持手段20が充填手段22を駆動し、貯留室27内の圧力を第1圧力よりも高い第2圧力として、接着シートAS全体に大きな押圧力を付与する構成としてもよい。なお、貯留室27内の気体を徐々に排出して被着面WK1に接着シートASを密着させるとき、貯留室27内の圧力を第1圧力よりも低い第3圧力としてもよい。   Here, a detection means (not shown) such as a pressure sensor for detecting the pressure in the storage chamber 27 or a load cell is provided, and the holding means 20 drives the discharge means 23 based on the detection result of the detection means. The gas may be gradually discharged while maintaining the pressure (first pressure). At this time, the pressing means 30 can drive the linear motor 31 to lower the holding member 21. Thereby, the deformation of the holding surface 25A can be promoted, and even when the unevenness of the adherend surface WK1 is large, the retainer surface 25A can follow the unevenness, and the adhesive sheet AS is brought into close contact with the adherend surface WK1. be able to. Further, after the gas is gradually exhausted and the adhesive sheet AS is brought into close contact with the adherend surface WK1 while the pressure in the storage chamber 27 is maintained, the holding unit 20 drives the filling unit 22 to It is good also as a structure which gives a big pressing force to the adhesive sheet AS whole as a 2nd pressure higher than a 1st pressure. In addition, when the gas in the storage chamber 27 is gradually discharged to bring the adhesive sheet AS into close contact with the adherend surface WK1, the pressure in the storage chamber 27 may be a third pressure lower than the first pressure.
次に、押圧手段30が直動モータ31の駆動を停止させた状態で、保持手段20が静電チャック26の駆動を停止し、接着シートASの保持を解除する。そして、保持手段20が充填手段22および排出手段23を駆動し、貯留室27内の気体の量を増減させ、被着体WKに貼付された接着シートASに対する押圧動作を1回または複数回行う貼付補助動作を実行する。この貼付補助動作は、図2に示すように、変形許容部25を収縮させて、被着体WKに貼付された接着シートASに対して保持面25Aを少なくとも1度離間させてから、再度貯留室27内の圧力を第1圧力にして当接させる。このような貼付補助動作を行った後、押圧手段30が直動モータ31を駆動し、保持部材21を図1中実線で示す位置に復帰させ、搬送手段CVがコンベア等を駆動し、接着シートASが貼付された被着体WKを次工程の装置等に搬送し、以降上記同様の動作が繰り返される。なお、貼付補助動作を行う度に第1圧力よりも高い第4圧力、第5圧力・・・となるように、貯留室27内の圧力を段階的に上昇させ、念押しの押圧が確実に接着シートASに付与されるように構成してもよい。また、貼付補助動作を行う際、保持面25Aを接着シートASから離間させなくてもよい。   Next, in a state where the pressing unit 30 stops driving the linear motor 31, the holding unit 20 stops driving the electrostatic chuck 26 and releases the holding of the adhesive sheet AS. Then, the holding unit 20 drives the filling unit 22 and the discharge unit 23 to increase or decrease the amount of gas in the storage chamber 27, and performs the pressing operation on the adhesive sheet AS attached to the adherend WK one or more times. Execute sticking assist operation. As shown in FIG. 2, the sticking assisting operation is performed by contracting the deformation allowing portion 25 and separating the holding surface 25A from the adhesive sheet AS attached to the adherend WK at least once, and then storing again. The pressure in the chamber 27 is brought into contact with the first pressure. After performing such a sticking assisting operation, the pressing means 30 drives the linear motor 31 to return the holding member 21 to the position indicated by the solid line in FIG. 1, and the conveying means CV drives the conveyor and the like, and the adhesive sheet The adherend WK to which the AS is affixed is conveyed to the next process apparatus or the like, and thereafter the same operation is repeated. It should be noted that the pressure in the storage chamber 27 is increased step by step so that the fourth pressure, the fifth pressure,. You may comprise so that it may be provided to adhesive sheet AS. Further, when performing the sticking assist operation, the holding surface 25A may not be separated from the adhesive sheet AS.
以上のような実施形態によれば、気体を貯留可能な変形許容部25により保持面25Aの変形を許容するため、従来のようにスポンジの側面から吸引用のエアが漏れるような不都合を防止し、接着シートASを確実に保持することができ、接着シートAS全体に適切な押圧力を付与することができる。   According to the embodiment as described above, since the deformation of the holding surface 25A is permitted by the deformation permitting portion 25 capable of storing gas, it is possible to prevent inconvenience that suction air leaks from the side surface of the sponge as in the past. The adhesive sheet AS can be reliably held, and an appropriate pressing force can be applied to the entire adhesive sheet AS.

Such an adhesive sheet AS is, for example, a single layer having only an adhesive AD layer, an adhesive layer having an intermediate layer between the base sheet BS and the adhesive AD layer, and a cover on the upper surface of the base sheet BS. It may be a layer having three or more layers, such as a so-called double-sided adhesive sheet that can peel the base sheet BS from the adhesive AD layer. It may have a multilayer intermediate layer, or may be a single layer or a multilayer without an intermediate layer. Examples of the adherend WK include food, resin containers, semiconductor wafers such as silicon semiconductor wafers and compound semiconductor wafers, information recording substrates such as circuit boards and optical disks, glass plates, steel plates, ceramics, wood plates, resin plates, and the like. Any form of member or article can also be targeted. In addition, the adhesive sheet AS is replaced with a functional and intended reading, for example, any information label, decorative label, protective sheet, dicing tape, die attach film, die bonding tape, recording layer forming resin sheet, etc. Arbitrary sheets, films, tapes, and the like can be attached to any adherend WK as described above.
