Description

【０００１】
【発明の属する技術分野】
この発明は、曲面形状でも皺を発生させることなく張り付けることができる圧力センサシートに関するものである。
【０００２】
【従来の技術】
圧力センサシートは、印加側端子とこれに配線接続された印加側電極が印刷形成されているベースフィルムと、レシーブ側端子とこれに配線接続されたレシーブ側電極が印刷形成されているベースフィルムとを、前記印加・レシーブ側電極相互間に感圧インク層を介在させる態様で粘着一体化して形成されている（例えば、特許文献１参照。）。この圧力センサシートでは、印加・レシーブ側電極相互間に感圧インク層を介在させた部分が感圧部と成り、この感圧部には多数の感圧素子が存在している。
【０００３】
しかしながら、従来の圧力センサシートＳは上述した如く二枚のベースフィルム８，９を貼り合わせた平面構造であるため、図８に示すように円筒体Ｐやその他円錐体の表面に張り付けた場合、内面側のベースフィルム９に図９に示すような皺が発生し、できた皺により無負荷状態で出力がでる異常出力となってしまう。
【０００４】
ここで、平面上の圧力センサシートを曲面に装着する場合には、一旦、感圧部分周りの粘着部分を切り取るか若しくは、粘着部分を剥がす等して、二枚のベースフィルム相互を剥離させ、円筒体Ｐに押し付けながら張り直すという作業が必要であった。
【０００５】
前者の場合、装着した際に改めて粘着剤を塗布するか又はテープ等で固定する必要があるため作業が煩雑である。また、テープで固定した場合には、水や蒸気等が当たる環境下ではセンサの封止が十分に行えない等の問題がある。
【０００６】
後者の場合、圧力センサシートの電極印刷面を破損させる恐れがあるという問題がある。
【０００７】
【特許文献１】
特許第３３３８９８３号公報（図２）
【０００８】
【発明が解決しようとする課題】
そこで、この発明では、▲１▼簡単な作業で、▲２▼センサを破損させることなく十分に封止ができ、▲３▼曲面形状でも皺を発生させることなく張り付けることができる圧力センサシートを提供することを課題とする。
【０００９】
【課題を解決するための手段】
（請求項１記載の発明）
この発明の圧力センサシートは、二枚のベースフィルム相互を感温性粘着剤で貼り合わせて成るものとしている。
（請求項２記載の発明）
この発明の圧力センサシートは、少なくとも、曲面形状部に張り付けられる二枚のベースフィルム部分相互が感温性粘着剤で貼り合わせて成るものとしている。
（請求項３記載の発明）
この発明の圧力センサシートは、請求項２記載の発明に関し、感圧部を構成する二枚のベースフィルム部分相互が、感温性粘着剤で貼り合わせてある。
【００１０】
この発明の圧力センサシートの作用・効果については、発明の実施の形態の欄で明らかにする。
【００１１】
【発明の実施の形態】
この発明の実施形態の圧力センサシートを図面に従って説明する。
〔実施形態１〕
図１はこの実施形態の圧力センサシートの部分斜視図、図２は前記圧力センサシートの感圧部の分解斜視図である。
（この圧力センサシートＳの構成について）
この圧力センサシートＳは、図３に示すように円筒体Ｐに巻き付ける態様で張り付けるためのものであり、図１に示すように、二枚のベースフィルム１，２相互を感温性粘着剤３で貼り合わせて成るものとしている。
【００１２】
ベースフィルム１には、図１や図２に示すように、感圧インク層１２で覆われた印加側電極１０とこれに配線１１で接続された印加側端子（図示せず）が印刷形成されており、他方、ベースフィルム２には、同図に示すように、感圧インク層２２で覆われたレシーブ側電極２０とこれに配線２１で接続されたレシーブ側端子（図示せず）が印刷形成されている。
【００１３】
そして、感圧インク層１２，２２の配設域相互を対向させる態様でベースフィルム１，２を貼り合わせた状態では、図１や図２に示すように、感圧インク層１２で覆われた印加側電極１０と、感圧インク層２２で覆われたレシーブ側電極２０とにより、感圧部Ｋ（図１における実線と破線が交互に描かれている部分）が構成されている。なお、感圧部Ｋにおいて、感圧インク層１２で覆われた印加側電極１０と、感圧インク層２２で覆われたレシーブ側電極２０との重なり部分が感圧素子として機能する。
【００１４】
また、この実施形態では、図１に示すようにベースフィルム１，２における感圧部Ｋの外側部分に貼り合わせ代１ａ，２ａを設けてあり、前記貼り合わせ代１ａ，２ａ相互は感温性粘着剤３により剥離不能となっている。
【００１５】
上記した感温性粘着剤３としては、アクリル系接着剤が使用されており、ベースフィルム１，２に厚さ５〜５０μｍ程度の層で塗布してある。ここで、感温性粘着剤３とは、環境温度により粘着性の有無が発現するもので、設定温度以上で粘着力を有し且つ設定温度以下で粘着力が無くなるタイプのものと、設定温度以下で粘着力を有し且つ設定温度以上で粘着力が無くなるタイプのものがある。ここでいう設定温度は感温性粘着剤３が粘着性を発現するかしないかの境界となる温度（スイッチング温度）をいい、粘着剤の組成変更により例えば２０〜６０℃の範囲で任意に設定することが可能なものである。この感温性粘着剤３としては、例えば特開２０００−３５１９５１、特開２０００−３５１９４６に示されたものが採用できる。また、感温性粘着剤３は、繰り返し使用を可能にすべく可逆性を有するものを採用してある。
【００１６】
また、感圧インク層１２，２２を形成するための感圧インクは、導電性インク（例えば黒鉛、ビニル樹脂及びブチル・セロソルブ・アセテートを含む）と、絶縁インク（例えば二酸化チタンのファイラー、ビニル樹脂のバインダー及びブチル・セロソルブ・アセテートの溶剤を含む）とから成り、感度はこれらの相対比率を変えることにより設定できる。
（この圧力センサシートＳの機能について）
この圧力センサシートＳを、図３に示すように円筒体Ｐに巻き付ける態様で張り付ける場合、以下のようにすればよい。
▲１▼．貼り合わせ代１ａ，２ａを剥離不能にしている感温性粘着剤３を、粘着力がほとんど無くなる温度まで冷却又は加温する。
▲２▼．上記冷却又は加温状態では、感温性粘着剤３は粘着力がほとんど無いので、貼り合わせ代１ａ，２ａ相互は簡単に剥離できる。
▲３▼．図３に示す如く、ベースフィルム１の感圧部相当部分を円筒体Ｐに巻付け、その後、ベースフィルム２の感圧部相当部分をベースフィルム１の上に沿わせるようにして巻付ける。このような方法を採ると、ベースフィルム１側は図４に示すように皺は発生することはない。
▲４▼．雰囲気温度になると、感温性粘着剤３には粘着力が戻り、貼り合わせ代１ａ，２ａ相互が粘着状態となり、ベースフィルム１，２相互は封止状態になる。
（この圧力センサシートＳの優れた点について）
▲１▼．この圧力センサシートＳでは、図４に示す如く皺が発生しないから、無負荷状態において異常出力が出ることはない。
▲２▼．従来の技術の欄に記載した前者の技術の如く、装着した際に改めて粘着剤を塗布したり又はテープ等で固定する必要がないため、作業が簡単である。
▲３▼．ベースフィルム１，２相互は封止状態になるから、水や蒸気等が当たる環境下でも使用できる。
▲４▼．貼り合わせ代１ａ，２ａを剥離不能にしている感温性粘着剤３を、粘着力がほとんど無くなる温度まで冷却又は温め，その後円筒体Ｐにベースフィルム１，２の感圧部相当部分を順に巻き付けるだけであるから、ベースフィルム１，２の電極印刷面を破損させる恐れは少ない。
（この圧力センサシートＳの使用について）
この実施形態１の圧力センサシートＳは、ロボットの指先、マニピュレータの腕部、ボールジョイントのシャフト部分等、円筒形の部分又は一部に巻き付ける態様で張り付けることができる。
（その他）
この実施形態１と同等の構成を用いれば、筒体の内面にも張り付けることができる。この場合においても、簡単な作業で、センサを破損させることなく十分に封止ができ、曲面形状でも皺を発生させることなく張り付けることができる。なお、この例としては、シリンダーの内面に張り付けて、シリンダーの当たりを見る場合に使用できる。
〔実施形態２〕
図５はこの実施形態の圧力センサシートの部分斜視図、図６は前記圧力センサシートを円錐体の傾斜面に貼り付けた状態を示す斜視図、図７は前記圧力センサシートの円錐殻内の傾斜面に張り付けた状態を示す斜視図である。
（圧力センサシートＳの構成について）
この圧力センサシートＳは、図６に示すように、円錘体Ｅの傾斜面に沿って張り付けるためのものであり、実施形態１と同様に二枚のベースフィルム４，５相互を感温性粘着剤３で貼り合わせて成るものとしている。
【００１７】
ここで、この圧力センサシートＳでは、円錘体Ｅの傾斜面に沿って張り付けることを考慮して、感圧部Ｋの平面視形状を図５に示すように扇形に形成してあり、ベースフィルム４，５における感圧部Ｋの外周側には貼り合わせ代４ａ，５ａを設けてある。
【００１８】
ベースフィルム４，５において、感圧インク層で覆われた電極とこれに配線で接続された端子が印刷形成されている点、前記感圧インク層相互を対向させる態様でベースフィルム４，５相互を貼り合わせて感圧部を構成する点等は実施形態１と同様である。
【００１９】
この圧力センサシートＳは上記のような構成であるので、実施形態１と同様の機能と優れた効果を奏することが明らかである。
（その他）
この実施形態２の圧力センサシートＳは、図７に示すように、円錐殻Ｅ１内の傾斜面に、張り付けることもできる。
〔他の実施形態〕
二枚のベースフィルム相互を感温性粘着剤で貼り合わせる部分は、▲１▼当該ベースフィルムの全周であってもよいし、▲２▼少なくとも、曲面形状部に張り付けられる二枚のベースフィルム部分、例えば感圧部を構成する二枚のベースフィルム部分のみであってもよい。▲２▼の場合、他の部分は通常の粘着剤で貼り合わせる。
【００２０】
また、上記実施形態１、２の感圧部にかえて、感圧インク層で覆われた一枚の大きな共通電極と、感圧インク層で覆われた多数の小さな電極とを、双方の感圧インク層を対向させて感圧部を採るものとすることができる。
【００２１】
【発明の効果】
この発明は上記のような構成であるから次の効果を有する。
【００２２】
発明の実施の形態の欄に記載した内容から、▲１▼簡単な作業で、▲２▼センサを破損させることなく十分に封止ができ、▲３▼曲面形状でも皺を発生させることなく張り付けることができる圧力センサシートを提供できた。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a pressure sensor sheet that can be stuck on a curved surface without generating wrinkles.
[0002]
[Prior art]
The pressure sensor sheet includes a base film on which an application-side terminal and an application-side electrode connected to the wiring are printed and formed, and a base film on which a reception-side terminal and a reception-side electrode connected to the wiring are printed and formed. Are integrally formed in such a manner that a pressure-sensitive ink layer is interposed between the application / reception-side electrodes (for example, see Patent Document 1). In this pressure sensor sheet, a portion where a pressure-sensitive ink layer is interposed between the application / reception-side electrodes serves as a pressure-sensitive portion, and the pressure-sensitive portion has a large number of pressure-sensitive elements.
[0003]
However, since the conventional pressure sensor sheet S has a planar structure in which the two base films 8 and 9 are bonded as described above, when the conventional pressure sensor sheet S is attached to the surface of the cylindrical body P or other conical bodies as shown in FIG. Wrinkles as shown in FIG. 9 are generated in the base film 9 on the inner surface side, and the wrinkles formed result in an abnormal output in which no output is generated.
[0004]
Here, when the pressure sensor sheet on a flat surface is mounted on a curved surface, once the adhesive part around the pressure-sensitive part is cut off or the adhesive part is peeled off, the two base films are separated from each other, It was necessary to re-stretch while pressing against the cylindrical body P.
[0005]
In the former case, it is necessary to apply a pressure-sensitive adhesive again or fix it with tape or the like at the time of mounting, so that the operation is complicated. Further, when the sensor is fixed with a tape, there is a problem that the sensor cannot be sufficiently sealed in an environment where water, steam, or the like is applied.
[0006]
In the latter case, there is a problem that the electrode printing surface of the pressure sensor sheet may be damaged.
[0007]

Japanese Patent No. 3338983 (FIG. 2)
[0008]
[Problems to be solved by the invention]
Therefore, according to the present invention, (1) a pressure sensor sheet that can be sufficiently sealed with a simple operation without damaging a sensor, and (3) can be stuck without generating wrinkles even in a curved surface shape. The task is to provide
[0009]
[Means for Solving the Problems]
(Invention of claim 1)
The pressure sensor sheet of the present invention is formed by bonding two base films to each other with a temperature-sensitive adhesive.
(Invention of claim 2)
In the pressure sensor sheet of the present invention, at least two base film portions attached to the curved surface portion are bonded to each other with a temperature-sensitive adhesive.
(Invention of claim 3)
In the pressure sensor sheet according to the second aspect of the present invention, two base film portions constituting the pressure-sensitive portion are bonded to each other with a temperature-sensitive adhesive.
[0010]
The operation and effect of the pressure sensor sheet of the present invention will be clarified in the section of the embodiment of the present invention.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
A pressure sensor sheet according to an embodiment of the present invention will be described with reference to the drawings.
[Embodiment 1]
FIG. 1 is a partial perspective view of a pressure sensor sheet of this embodiment, and FIG. 2 is an exploded perspective view of a pressure-sensitive portion of the pressure sensor sheet.
(About the configuration of the pressure sensor sheet S)
This pressure sensor sheet S is to be attached in a manner of being wound around a cylindrical body P as shown in FIG. 3, and as shown in FIG. It is assumed to be formed by bonding at step 3.
[0012]
As shown in FIGS. 1 and 2, an application-side electrode 10 covered with a pressure-sensitive ink layer 12 and an application-side terminal (not shown) connected to this by a wiring 11 are formed on the base film 1 by printing. On the other hand, on the base film 2, as shown in the figure, a receiving-side electrode 20 covered with a pressure-sensitive ink layer 22 and a receiving-side terminal (not shown) connected to this by a wiring 21 are printed. Is formed.
[0013]
Then, in a state where the base films 1 and 2 are stuck together so that the arrangement areas of the pressure-sensitive ink layers 12 and 22 face each other, the base films 1 and 2 are covered with the pressure-sensitive ink layer 12 as shown in FIGS. The application-side electrode 10 and the reception-side electrode 20 covered with the pressure-sensitive ink layer 22 constitute a pressure-sensitive portion K (a portion where solid lines and broken lines in FIG. 1 are alternately drawn). In the pressure-sensitive portion K, an overlapping portion between the application-side electrode 10 covered with the pressure-sensitive ink layer 12 and the receive-side electrode 20 covered with the pressure-sensitive ink layer 22 functions as a pressure-sensitive element.
[0014]
In this embodiment, as shown in FIG. 1, bonding margins 1a and 2a are provided outside the pressure-sensitive portions K of the base films 1 and 2, and the bonding margins 1a and 2a are temperature-sensitive. The adhesive 3 makes it impossible to peel off.
[0015]
An acrylic adhesive is used as the above-mentioned temperature-sensitive adhesive 3, which is applied to the base films 1 and 2 in a layer having a thickness of about 5 to 50 μm. Here, the temperature-sensitive adhesive 3 is a material which exhibits the presence or absence of adhesiveness depending on the environmental temperature. The temperature-sensitive adhesive 3 has a tackiness at a temperature equal to or higher than a set temperature and loses the tackiness at a temperature lower than the set temperature. There is a type which has adhesive strength below and loses adhesive strength at a temperature higher than a set temperature. The set temperature here refers to a temperature (switching temperature) that is a boundary between whether or not the temperature-sensitive adhesive 3 exhibits adhesiveness, and is arbitrarily set within a range of, for example, 20 to 60 ° C. by changing the composition of the adhesive. It is possible to do. As the temperature-sensitive adhesive 3, for example, those described in JP-A-2000-351951 and JP-A-2000-351946 can be employed. The temperature-sensitive adhesive 3 has reversibility so that it can be used repeatedly.
[0016]
The pressure-sensitive ink for forming the pressure-sensitive ink layers 12 and 22 includes a conductive ink (for example, including graphite, vinyl resin and butyl cellosolve acetate), and an insulating ink (for example, titanium dioxide filer, vinyl resin). And a solvent of butyl cellosolve acetate), and the sensitivity can be set by changing the relative ratio thereof.
(About the function of this pressure sensor sheet S)
In a case where the pressure sensor sheet S is attached in such a manner as to be wound around the cylindrical body P as shown in FIG. 3, the following may be performed.
▲ 1 ▼. The temperature-sensitive adhesive 3, which makes the bonding margins 1a and 2a unpeelable, is cooled or heated to a temperature at which the adhesive strength is almost eliminated.
▲ 2 ▼. In the above-mentioned cooling or heating state, since the temperature-sensitive adhesive 3 has almost no adhesive strength, the bonding margins 1a and 2a can be easily separated from each other.
(3). As shown in FIG. 3, a portion corresponding to the pressure-sensitive portion of the base film 1 is wound around the cylindrical body P, and then the portion corresponding to the pressure-sensitive portion of the base film 2 is wound along the base film 1. When such a method is employed, wrinkles do not occur on the base film 1 side as shown in FIG.
▲ 4 ▼. When the ambient temperature is reached, the adhesive force returns to the temperature-sensitive adhesive 3, the bonding margins 1a and 2a are in an adhesive state, and the base films 1 and 2 are in a sealed state.
(About the excellent point of this pressure sensor sheet S)
▲ 1 ▼. In this pressure sensor sheet S, no wrinkles are generated as shown in FIG. 4, so that no abnormal output is generated in the no-load state.
▲ 2 ▼. Unlike the former technique described in the section of the prior art, there is no need to apply an adhesive or fix it with a tape or the like at the time of mounting, so that the operation is simple.
(3). Since the base films 1 and 2 are in a sealed state, the base films 1 and 2 can be used even in an environment where water, steam, or the like is applied.
▲ 4 ▼. The temperature-sensitive adhesive 3, which makes the bonding margins 1a and 2a non-peelable, is cooled or heated to a temperature at which the adhesive strength is almost eliminated, and then the portions corresponding to the pressure-sensitive portions of the base films 1 and 2 are sequentially wound around the cylinder P. Therefore, there is little risk of damaging the electrode printing surfaces of the base films 1 and 2.
(About the use of this pressure sensor sheet S)
The pressure sensor sheet S of the first embodiment can be attached to a cylindrical part or a part such as a fingertip of a robot, an arm part of a manipulator, a shaft part of a ball joint, or the like.
(Other)
If a configuration equivalent to that of the first embodiment is used, it can be attached to the inner surface of the cylindrical body. Even in this case, the sensor can be sufficiently sealed with a simple operation without damaging the sensor, and can be stuck without causing wrinkles even in a curved surface shape. In addition, as an example of this, it can be used in a case where it is attached to the inner surface of a cylinder to see the contact of the cylinder.
[Embodiment 2]
FIG. 5 is a partial perspective view of the pressure sensor sheet of this embodiment, FIG. 6 is a perspective view showing a state in which the pressure sensor sheet is attached to an inclined surface of a cone, and FIG. It is a perspective view showing the state where it was stuck on the slope.
(About the configuration of the pressure sensor sheet S)
As shown in FIG. 6, this pressure sensor sheet S is for attaching along the inclined surface of the cone E, and as in the first embodiment, the two base films 4, 5 are thermosensitive. It is made to adhere by the adhesive 3.
[0017]
Here, in the pressure sensor sheet S, in consideration of sticking along the inclined surface of the conical body E, the shape of the pressure-sensitive portion K in plan view is formed in a fan shape as shown in FIG. Lamination margins 4a and 5a are provided on the outer peripheral side of the pressure-sensitive portion K in the base films 4 and 5.
[0018]
In the base films 4 and 5, electrodes covered with the pressure-sensitive ink layer and terminals connected to the electrodes by printing are formed by printing, and the base films 4 and 5 are mutually opposed so that the pressure-sensitive ink layers face each other. Are the same as those in the first embodiment in that the pressure-sensitive portion is formed by bonding together.
[0019]
Since the pressure sensor sheet S has the above-described configuration, it is apparent that the pressure sensor sheet S has the same functions and excellent effects as those of the first embodiment.
(Other)
As shown in FIG. 7, the pressure sensor sheet S of the second embodiment can be attached to an inclined surface in the conical shell E1.
[Other embodiments]
The portion where the two base films are bonded to each other with the temperature-sensitive adhesive may be (1) the entire circumference of the base film, or (2) at least the two base films to be attached to the curved surface portion. A portion, for example, only two base film portions constituting a pressure-sensitive portion may be used. In the case of (2), the other parts are bonded with a normal adhesive.
[0020]
In addition, instead of the pressure-sensitive portions of the first and second embodiments, one large common electrode covered with a pressure-sensitive ink layer and a large number of small electrodes covered with a pressure-sensitive ink layer are connected to each other. The pressure-sensitive portion may be adopted by facing the pressure ink layer.
[0021]
【The invention's effect】
The present invention has the following effects because it has the above configuration.
[0022]
From the contents described in the embodiments of the invention, (1) simple operation, (2) sufficient sealing without damaging the sensor, and (3) bonding without wrinkling even with a curved surface shape. The pressure sensor sheet which can be provided can be provided.
