【発明の属する技術分野】
本発明は、文字板、文字板の製造方法および時計に関する。より詳しくは、表面に文字などの装飾部材を備えた文字板、その製造方法およびその文字板を備えた時計に関する。
【0002】
【背景技術】
従来より、時計の文字板に文字等の装飾部品を装飾する方法として、装飾部品を粘着剤によって文字板に貼り付ける方法が知られている。この方法によると、まず装飾部品の裏に粘着剤を塗布しておき、粘着剤側に剥離紙を、また装飾部品側に転写シートを貼って三層構造のシールを構成する。装飾部品を文字板に貼る際には、剥離紙を剥がし、粘着剤を文字板に貼り付けた後に転写シートを剥がして装飾部品を文字板に転写する。この際、粘着剤としては通常、水分が蒸発することで粘着性を調整する水溶性のものや、溶剤を揮発させて粘着性を調整する溶剤性のもの、紫外線(UV)を照射することで粘着性を調整するものなどが使用されている。
【0003】
【発明が解決しようとする課題】
ところが、転写シートを剥がした後の装飾部品の外周部分には粘着剤の層が露出しているため、微小なゴミが粘着剤に張り付いたままの状態となって、文字板の外観を損ねてしまう場合がある。このような微小なゴミを除去するために細い綿棒等に溶剤をつけてふき取る方法も考えられる。しかしながらこの方法では、作業工数が増えるばかりでなく、溶剤で粘着剤が糸状に尾をひいてしまうので、文字板を汚してしまうことがある。あるいは、綿棒等で触れるために粘着剤が動いて装飾部品の位置がずれてしまうなどの不都合がある。また、ふき取った後に溶剤が完全に除去されていないと、シミの原因になる。
文字板にエアーを吹き付けて除去する方法も考えられるが、この方法では粘着剤に粘着したゴミを確実に除去することは難しい。
【0004】
本発明の目的は、装飾部品の外周部分にゴミが粘着せず、外観の良好な文字板を提供することにある。また、本発明の他の目的は、外観の良好な文字板の製造方法を提供することにある。さらに、本発明の他の目的は、外観の良好な文字板を備えた時計を提供することにある。
【0005】
【課題を解決するための手段】
そのため、本発明の文字板は、文字基板と、この文字基板の上に接着部を介して接着された装飾部材とを備えている文字板において、接着部は、流動性を有する粘着手段と、固化あるいは硬化によって接着部を不可逆的に流動状態から固体状態へ相転移させる不可逆相転移手段とを含んで構成されていることを特徴とする。
ここで、固化とは、水分や溶剤を取り除くことによって接着部を固体化させることをいう。また、硬化とは、重合反応によって接着部を固体化させることをいい、例えば紫外線(UV)などを照射して固体化させる光硬化や、加熱や熱線の照射などにより固体化させる熱硬化などがある。
この構成の文字板では、接着部を構成する粘着手段によって装飾部材が文字基板に良好に接着される。なおかつ、粘着手段によって良好な接着力を維持したまま、不可逆的相転移手段によって接着部全体あるいは装飾部材の外周部分を固体状態に相転移させることができるため、相転移後には微小なゴミが接着部に粘着することがなく、文字板の外観が良好になる。
また、この構成の文字板によれば、従来とは異なって、溶剤などでゴミをふき取るなどの工程が不要になるので、製造工程が簡略化される。
【0006】
また、この際、粘着手段は、溶剤を揮発させることにより粘着性を調整する溶剤性粘着型、水分を蒸発させることにより粘着性を調整する水溶性粘着型、および紫外線(UV)を照射することにより粘着性を調整するUV粘着型のいずれかであることが望ましい。
この構成の文字板では、粘着手段はそれぞれ所定の処理を行うことにより粘着性を調整できるので文字板の製造が簡単かつ確実である。ここで、所定の処理とは、例えば溶剤性粘着型や水溶性粘着型の粘着手段の場合では、装飾部材に塗布された接着部を一定時間放置したり、加熱によって溶剤の揮発や水分の蒸発を促進するなどの方法をいう。また、UV粘着型の粘着手段の場合では、所定の光量の紫外線(UV)を照射することをいう。これにより、接着部の粘着性を簡単に調整でき、装飾部材が文字基板に良好に接着する。
【0007】
また、本発明の文字板では、不可逆相転移手段は、紫外線(UV)を照射することにより硬化するUV硬化型、または加熱することにより硬化する熱硬化型であることが望ましい。
この構成の文字板では、接着部はそれぞれ所定の処理を行うことにより所望の時期に固体化させることができる。例えば、装飾部材を文字基板に接着した状態でこの処理を行えば、装飾部材と文字基板とが良好な接着力を維持したまま接着部を固体化させることができる。したがって、装飾部材の外周部分へのゴミの粘着が簡単かつ確実に防止される。ここで、所定の処理とは、UV硬化型の不可逆相転移手段を使用する場合では、所定の光量の紫外線を照射することをいう。また、熱硬化型の不可逆相転移手段を使用する場合には、所定の温度で加熱することをいう。これらの処理により、簡単に接着部を固体化することができる。
【0008】
以上のような文字板の製造方法は、少なくとも装飾部材の接着面に接着部を有し、装飾部材の接着部を有する側に剥離シートが貼られ、かつ装飾部材の剥離シートが設けられた側とは反対側に転写シートが貼られたシート状のシールを用いて製造する文字板の製造方法であって、シート状のシールの接着部を、予め流動性を有する粘着手段と固化あるいは硬化によって接着部を不可逆的に流動状態から固体状態に相転移させる不可逆相転移手段とを含んで構成しておき、シート状のシールの剥離シートを剥がし、剥離シートを剥がして接着部が露出した面を粘着手段により文字基板に貼り付け、文字基板に貼り付けられた装飾部材から転写シートを剥がした後に、文字基板および装飾部材の間の接着部を不可逆的に流動状態から固体状態に相転移させることを特徴とする。
【0009】
この方法の文字板の製造方法では、シート状のシールに形成された装飾部材を接着部の粘着力によって文字基板に転写する。その後、接着部を不可逆的に流動状態から固体状態に相転移させるので、装飾部材は良好な接着力を維持したまま文字基板に固定される。接着部が固体状態に相転移しているので、装飾部材の外周部分に微小なゴミが粘着せず、外観が良好となる。また、これにより、従来とは異なって、ゴミを溶剤などでふき取る作業が不要となり、製造工程が簡略化する。
【0010】
あるいは、以上のような文字板の製造方法は、少なくとも装飾部材の接着面に接着部を有し、装飾部材の接着部を有する側に剥離シートが貼られ、かつ装飾部材の剥離シートが設けられた側とは反対側に転写シートが貼られたシート状のシールを用いて製造する文字板の製造方法であって、シート状のシールの接着部を、予め流動性を有する粘着手段と固化あるいは硬化によって接着部を不可逆的に流動状態から固体状態へ相転移させる不可逆相転移手段とを含んで構成しておき、シート状のシールの剥離シートを剥がし、剥離シートを剥がして接着部が露出した面を粘着手段により文字基板に貼り付け、文字基板および装飾部材の間の接着部を不可逆的に流動状態から固体状態に相転移させた後に、装飾部材から転写シートを剥がすことを特徴とする。
【0011】
この方法の文字板の製造方法では、シート状のシールに形成された装飾部材を接着部の粘着力によって文字基板に転写する。その後、転写シートを剥がす前に、接着部を不可逆的に流動状態から固体状態に相転移させる。つまり、装飾部材が転写シートで保護された状態で接着部が固体状態に相転移される。よって、ゴミの粘着がより一層確実に防止される。
また、例えば接着部が装飾部材の接着面だけでなく、装飾部材が配置されていない部分の転写シートにも連続して設けられている場合がある。この場合には特に、接着部が固体状態に相転移してから転写シートを剥がすので、装飾部材が配置されてない部分の接着部が文字基板に粘着せず、文字基板上に余分な接着部が残らない。よって、外観が良好になる。
さらに、従来では、転写シートを剥がす際に装飾部材の外周部分で接着部が分離しにくく、装飾部材の外周部分に残ってしまう場合があった。本発明の文字板の製造方法では、転写シートを剥がす時に接着部が既に固体状態に相転移している。したがって、接着部が伸びずに装飾部材の外周部分で分離されやすく、装飾部材の外周部分に接着部がはみ出さない。したがって外観が良好な仕上がりとなる。特に不可逆相転移手段としてUV硬化型のものを使用する場合には、装飾部材と文字基板との間に配置された接着部は紫外線が照射されにくいので半硬化となる。一方、その他の装飾部材が配置されていない部分の接着部は完全に硬化する。よって、転写シートを剥がす際に装飾部材の外周部分で接着部が良好に分離される。
【0012】
また、このような文字板は、前述のようにゴミの粘着がなく、外観が良好となるので、時計の文字板に使用されることに適している。
【0013】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。
図1には、本実施形態に係る文字板1(図6参照)の製造に用いられる文字シール3の一部断面図が示されている。文字シール3は、文字基板4(図6参照)に装飾される装飾部材としての文字部材2をシート状に形成したものである。
【0014】
この図1において、文字部材2は、文字や数字(本実施形態では数字)の形状に形成され、複数の文字部材2が文字基板4に接着される配置で設けられている。この文字部材2は、文字基板4と接着する面が平面状の接着面2Aとなっている。また、接着面2Aの反対側の面は、文字基板4に接着したときに外部から視認可能な断面円弧状の凸部2Bとなっている。
文字部材2は電鋳めっきによって形成され、形成後のめっき応力が小さくなるように、例えばニッケル(Ni)、銅(Cu)、金(Au)、銀(Ag)などの材料からなる。
【0015】
文字部材2の凸部2Bには、その凸部2Bの形状に沿うように透明なフィルム状の転写シート6が密着されている。この転写シート6には、文字部材2が密着する側の面に図示しない接着剤が塗布されており、適度な接着力で文字部材2と接着されている。転写シート6は、文字部材2を文字基板4に転写する際に文字部材2の相互の位置ずれを防止する他、文字部材2に傷がつかないように文字部材2の保護シートも兼ねている。
ここで、転写シート6の材料としては、文字部材2に対して剥離が容易でかつ密着しやすい非通気性の材料であればよく、例えばポリエチレンやポリプロピレンなどの軟質のフィルムなどが採用できる。
【0016】
文字部材2の接着面2Aおよび文字部材2が配置されていない部分の転写シート6には、これらを文字基板4に接着するための接着部としての接着剤7が塗布されている。この接着剤7は、流動性を有する粘着手段としての粘着剤と、固化または硬化により接着剤7を不可逆的に流動状態から固体状態に相転移させる不可逆相転移手段としての硬化剤とを含んで構成されている。
ここで、粘着剤としては、例えば溶剤を揮発させることにより粘着性を調整する溶剤性粘着型や、水分を蒸発させることにより粘着性を調整する水溶性粘着型、紫外線(UV)を照射することにより粘着性を調整するUV粘着型などが採用できる。溶剤性粘着型としては、例えばウレタン系樹脂などが採用でき、また、水溶性粘着型およびUV粘着型としては、アクリル系樹脂などが採用できる。
また、硬化剤としては、例えば加熱することにより硬化する熱硬化型や、紫外線を照射することにより硬化するUV硬化型などが採用できる。熱硬化型としては、例えばエポキシ系樹脂などが採用でき、また、UV硬化型としてはアクリル系樹脂などが採用できる。
【0017】
なお、粘着剤および硬化剤の材料の選定やこれらの配合比などは、両者の材料の相性や、必要とされる接着力等を勘案して適宜決定される。つまり、例えば溶剤性粘着型とUV硬化型とを組み合わせる場合には、ウレタン系樹脂とアクリル系樹脂とを適切な配合比で混合する。この配合比によって、UV硬化型を硬化させた際に接着力が向上したり、低下したりする。よって、配合比および材料は、耐久性向上のため強固な接着力を得たい場合や、製品のモデルチェンジの容易性を考慮して、比較的接着力を小さな値に設定したい場合など、使用される目的に合わせて適宜選定される。
【0018】
文字部材2の接着面2A側には、接着剤7と密着するように剥離シート8が設けられている。剥離シート8の材料は、非通気性で接着剤7との剥離性が良好な、例えばフッ素系樹脂を表面に処理した紙や、樹脂製のフィルムなどで構成されている。この剥離シート8により、接着剤7へのゴミの粘着や接着剤7の溶剤の揮発あるいはや水分の蒸発が防止されている。
【0019】
このような文字シール3は、例えば縦横に複数個の文字シール3を整列させて文字シート13(図4参照)を形成し、これを切断することにより製造する。以下に文字シール3の製造方法について説明する。
【0020】
文字シール3は、電鋳めっきによって製造した文字部材2をシート状のシールに形成することにより製造する。そこで、まず、文字部材2の製造方法について説明する。
図2には、文字部材2を電鋳めっきによって製造する製造工程が示されている。文字部材2を製造するには、まず、図2(A)および(B)に示されるように、板状の基材9の片面にレジスト剤10を塗布する。
基材9は、めっきの厚さが均一になるように表面仕上げが平滑な鏡面状態からなることが好ましい。なお、基材9の表面が平滑でない場合には、銅めっきを下地めっきとして施し、平滑化すればよい。基材9の材料は、導電性を有するものであればよく、例えば洋白(NS)や、銅(Cu)、鋼材などが採用できる。あるいは、非導電性の材料の表面に導電性皮膜処理を施したものでもよい。基材9の大きさは、多数の文字シール3が縦横に複数個整列配置された大きさを有していればよい。また、基材9の厚さも、作業性、取扱性の良好な強度を有する厚さであればよく、基材9の材質や大きさなどを勘案して適宜決定される。
【0021】
レジスト剤10は、非導電性で、望ましくは露光現像タイプのものが使用でき、印刷や、塗装、フィルム貼付等の方法により基材9の表面に形成される。このレジスト剤10により、基材9の片面に耐酸性、非導電性の層が形成される。レジスト剤10の厚さは、文字部材2の厚さや太さなどを勘案して適宜決定される。一般的には、10μm以上の厚さであれば、良好な立体的な文字部材2を得ることができる。厚めっきを施したい場合には、文字部材2の寸法精度を確保するためレジスト剤10の厚さも厚くする必要がある。この場合には、フィルム状のレジスト剤を重ねて所望の厚さに設定すればよい。
【0022】
次に図2(C)に示されるように、文字部材2の形状のネガ11を作成する。そして、このネガ11を基材9のレジスト剤10が塗布された面に被せ、紫外線露光Eを行う。ここで、ネガ11の形状は、電鋳めっきを施した際に形成される文字部材2の形状が所望の寸法となるように、予め諸工程で発生する寸法誤差を補正値として盛り込んだ寸法で作成する。
【0023】
その後に、紫外線露光Eが施された基材9を、図2(D)に示されるように一般的なアルカリ現像あるいは溶剤方式などの方法によって現像する。すると、ネガ11の形状に沿ってレジスト剤10が除去される。これにより、文字部材2とほぼ同じ形状に導電性の基材9が露出しためっき形成部9Aを形成する。
その後、図2(E)に示されるように、基材9のめっき形成部9Aの反対側の面(裏面)にマスキング層12を形成する。マスキング層12は、電鋳めっきを行う際に導電性を有する基材9の裏面にめっきが形成されるのを防止するために施すものである。マスキング層12は、非導電性の材料で構成され、例えば合成樹脂などの塗料を塗装やスクリーン印刷によって塗布したり、合成樹脂製のフィルムを貼り付けるなどの方法により形成する。
【0024】
このような基材9に、図2(F)に示されるように電鋳めっきを施す。この際、基材9の導電性を確保し、なおかつ電鋳めっきによって形成された文字部材2が基材9から剥離しやすくする必要がある。そこで、電鋳めっきを施す前に、基材9に活性化処理および不動態化処理を行う。
その後、電鋳めっき槽で基材9に電鋳めっき形成を行う。電鋳めっきは、一般的な電気めっきの条件で行われる。めっき液の材料は、前述のような文字部材2に使用される材料などである。電鋳めっきの厚さは、所望の外観上の立体感が得られるように適宜設定される。この電鋳めっきにより、基材9上のめっき形成部9Aには、めっき液が充填され、さらに、このめっき形成部9Aから一部はみだして、肉盛り状に凸部2Bが形成される。
電鋳めっき後、所望の厚さに形成された文字部材2に、色調や仕上げのバリエーションを持たせるために、様々な後処理を施してもよい。このような後処理としては、例えばAuめっきや、Rhめっき、黒Niめっき、Snめっき、黒Crめっき、つや消しNiめっき等などがある。あるいは、吹きつけ塗装、電着塗装等により着色してもよい。
【0025】
次に、以上のような方法で形成された文字部材2を、文字シート13に形成する方法について説明する。
図3には、文字シート13の製造工程が示されている。この図3(A)に示されるように、まず、電鋳めっきによって形成された文字部材2の凸部2Bを含む基材9に転写シート6を密着させる。この状態で、図3(B)に示されるように、転写シート6を基材9から剥離させる。転写シート6には、前述のように接着剤が塗布してあるので、凸部2Bは転写シート6に粘着する。一方、基材9には文字部材2が剥離しやすいように処理が施されている。ここで、基材9と文字部材2との接着力は、文字部材2と転写シート6との接着力より弱くなるように設定されている。したがって、文字部材2は、転写シート6を剥離するにしたがって、基材9から転写シート6に転写される。
【0026】
次に、図3(C)に示されるように、文字部材2の接着面2Aに接着剤7をスプレーやスクリーン印刷等の方法で塗布する。接着剤7の厚さは、文字部材2および文字基板4の形状、寸法や表面粗さなどを勘案して適宜設定され、例えば20μm以上などに設定される。スクリーン印刷の方法による場合には、接着剤7の粘度とスクリーンのメッシュの粗さによって塗布厚さを設定でき、均一な厚さで平滑な表面が得られる。接着剤7は、転写シート6の全面に塗布するため、転写シート6上の文字部材2がない部分にも塗布される。
この際、作業の簡便性を考慮して流動性を有する液状体の接着剤7を塗布する。そして、その後接着剤7に所定の処理を施すことにより粘着性を調整する。ここで、所定の処理とは例えば、溶剤性粘着型や水溶性粘着型の粘着剤を含む接着剤7では、接着剤7を転写シート6に塗布後、放置することによって溶剤を揮発あるいは水分を蒸発させて粘着性を調整する。または、接着剤7を加熱することにより、溶剤の揮発や水分の蒸発を促進してもよい。この場合には、転写シート6の耐熱温度を勘案して所定温度を設定し、例えば100℃以下で加熱すればよい。
【0027】
接着剤7に粘着性を持たせた後、図3(D)に示されるように、接着剤7の塗布面に剥離シート8を貼る。
以上の方法により、文字部材2は、接着面2Aに接着剤7を有し、両面を転写シート6および剥離シート8に覆われた文字シート13に形成される。この文字シート13は、図4に示されるように、多数の文字シール3が縦横に連続的に配置されているものである。よって、文字シール3を使用する際には、文字シート13の供給形態に合わせて必要に応じて文字シート13を切断すればよい。文字シート13を切断する場合には、例えばカッティングマシン等を使用して、あるいは手作業により切り出す。
【0028】
このようにして形成された文字シール3を文字基板4に貼り付けて文字板1を製造する方法について説明する。
まず、文字部材2との密着性をよくするために、文字基板4の汚れを予め洗浄などによって除去する。ここで、文字基板4は、図示はしないが略四角形状の平板状部材で、中央に形成された文字板形成部と、この文字板形成部の周囲に形成された把持部とを備える。文字板形成部と把持部との間には溝などが形成され、両者が切断されやすくなっている。また、把持部には、文字部材2の貼付時に位置決めをするための位置決め用孔が設けられている。
このような文字基板4を文字部材2に対して位置決めするために貼付治具に固定する。貼付治具には、文字基板4を位置決めするためのピンが設けられている。このピンに文字部材2の位置決め用孔を合わせ、位置決めを行う。なお、把持部を有さず、文字板形成部のみで文字基板4が構成されている場合には、文字基板4の外周に切り欠き等を設けて位置決めを行えばよい。
【0029】
一方、文字シート13から切り出された一つの文字シール3の剥離シート8を、図5(A)に示されるように剥がす。ここで、剥離シート8と接着剤7との接着力は、接着剤7と転写シート6との接着力より弱くなるように設定されているので、剥離紙8を剥がすと文字部材2および接着剤7は転写シート6に残る。
次に、剥離シート8を剥がして接着剤7が露出した面を図5(B)で示されるように、文字基板4に貼り付ける。ここで、図1に示されるように、文字部材2が配置されている領域の外側両端には、文字基板4に対して貼り付け位置を規定するための位置決め部5が設けられている。この位置決め部5は、互いに平行に配置された棒状部5Aと、この棒状部5Aの長さ方向中央に形成された位置決め孔5Bとを有する。よって、貼付治具に設けられた別のピンに位置決め部5の位置決め孔5Bを合わせることにより、文字部材2を文字基板4に対して位置決めする。文字部材2が文字基板4上の所定の位置に配置された後、これらの文字部材2を文字基板4に確実に密着させるために転写シート6の上から加圧する。
【0030】
次に、図5(C)に示されるように、転写シート6を剥がす。この際、文字部材2は加圧されて文字基板4に密着しており、文字部材2を押さえながら転写シート6を剥がすと、文字部材2は文字基板4に接着されて残る。一方、文字部材2のない部分の接着剤7である周辺部7Aは転写シート6に接着して一緒に剥がれ、文字部材2と文字基板4との間の接着剤7である文字下部7Bと分離される。したがって、この際には、転写シート6と接着剤7との接着力は、接着剤7と文字基板4との接着力よりも大きな値に設定されることが望ましい。また、接着剤7と文字基板4との接着力は、文字部材2と転写シート6との接着力よりも大きな値に設定されることが望ましい。このような条件下では、周辺部7Aが転写シート6とともに良好に剥がれる。なお、このような条件を満たすことが難しい場合でも、文字部材2を押さえながら転写シート6を剥がすことにより、文字部材2を文字基板4に残し、周辺部7Aを転写シート6とともに剥がすことができる。
【0031】
このような状態で、図5(D)に示されるように、接着剤7を不可逆的に流動状態から固体状態に相転移、つまり固体化させる。固体化させる方法は、使用している硬化剤によって異なる。例えば、熱硬化型の硬化剤を用いている場合には、文字部材2が接着された文字基板4を加熱する。加熱Fの温度は、硬化剤の材質や文字部材2および文字基板4の材質等を勘案して設定され、例えば120℃以上で加熱される。なお、この際に加熱Fとともに赤外線や遠赤外線等の熱線の照射を併用してもよい。また、例えば、UV硬化型の硬化剤を用いている場合では、所定の光量の紫外線Fを接着剤7に向かって照射する。紫外線Fの光量は、UV硬化型の硬化剤の材質によって異なるが、一般的には光量が800 mj/cm以上となるように設定される。
なお、粘着剤にUV粘着型を用い、硬化剤にUV硬化型を用いた場合には、UVの照度を調節することによって粘着性を調整し、後に光硬化を行う。この場合は、一般的にUV硬化型はUV粘着型よりも多くの照度を必要とし、例えば150 mW/cm以上の照度で光硬化を行う。
また、UV硬化型の硬化剤を用いる場合には、UVを照射すると文字部材2の外周部分の硬化剤は硬化する。この時、文字部材2の形状によっては内部の硬化剤が文字部材2に被われて硬化しない場合がある。そのような場合でも、文字下部7Bの内周部分は粘着剤の粘着力により良好に粘着し、かつ文字下部7Bの外周部分は確実に硬化する。
【0032】
このような方法によって文字部材2が貼り付けられた文字基板4の文字板形成部を、把持部との間に形成された溝などに沿って切断することにより、図6に示されるような文字板1を形成する。なお、把持部を備えていない文字基板4の場合には、このような切断工程が不要となる。
【0033】
以上のような実施形態によれば、次のような効果が得られる。
接着剤7に粘着剤と硬化剤とが設けられているので、所望の時期に粘着性および硬化性を得ることができる。つまり、文字部材2を文字基板4に貼り付ける際には粘着性が調整されているので、両者を良好に接着できる。また、文字部材2を貼り付けた後に硬化剤によって接着剤7が硬化されるので、文字部材2の外周部分に微小なゴミが粘着しない。そして、文字部材2の外周部分に微小なゴミが付着した場合でも、エアーなどを吹き付けることによって容易に除去できる。したがって、外観を良好にできる。なお、硬化剤としてUV硬化型のものを使用した場合でも、文字下部7Bの外周部分は、UV照射により確実に硬化しているため、微小なゴミが粘着せず、外観を良好にできる。そして、文字下部7Bの内部は半硬化の状態となるため、粘着剤によって良好に粘着できる。
【0034】
また、従来文字部材2の外周部分に付着したゴミを溶剤を含浸させた綿棒などで除去していたが、本実施形態によれば微小なゴミの粘着が防止されるので、このような作業が不要となる。したがって、文字板1の製造工程が簡略化できる。さらに、溶剤でふき取る作業によって文字部材2の配置がずれてしまったり、文字基板4にシミを付着させてしまったりすることがないので、不良品を減少でき、歩留まりを向上させることができる。
【0035】
従来の粘着剤では製品完成後にも粘着剤が流動性を有するので、外力が加わると文字部材2の位置が動いたり、取れたりすることがあった。しかし、本実施形態によれば、接着剤7を硬化させるので、文字部材2を文字基板4の確実に固定できる。

接着剤7の粘着剤は、溶剤性粘着型、水溶性粘着型、UV粘着型等が用いられているので、それぞれ前述のような処理を施すことにより所望の時期に確実に粘着性を調整させることができる。
また、接着剤7の硬化剤は、UV硬化型、熱硬化型等が用いられているので、前述のような処理を施すことにより所望の時期に確実に接着剤7を硬化させることができる。

このような文字板1が時計に適用されれば、微小なゴミの粘着を防止でき、外観を良好にできる。
【0038】
なお、本発明は前述の実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれるものである。
例えば、前記実施形態では、文字板1に配置される全ての文字部材2を一つの文字シール3に形成したが、本発明ではこれに限らない。例えば、一つの文字部材2を一つの文字シール3として形成してもよい。あるいは、一つの文字板1に色違いや素材違いの文字部材2が配置される場合などでは、色や素材によって文字シール3を複数枚形成してもよい。
また、文字部材2は数字であったが、これに限らず文字、マーク、メーカー名、商品名のロゴ、注意事項や、その他装飾模様等の任意の形状であってよい。
さらに、文字板1は、現在時刻を表示するものに限らず、日を表示する日車や、曜を表示する曜車などでもよい。
【0039】
文字部材2を文字基板4に貼り付ける時には、本実施形態では転写シート6を文字基板4から剥がした後に接着剤7を固体化させていたが、転写シート6を剥がす前に固体化させてもよい。
つまり、図7に示されるように、(B)において文字部材2を文字基板4に貼り付けた後、図7(C)に示されるように、硬化剤の材料に応じて加熱、加熱および熱線照射を組み合わせたものやUV照射を行い、硬化剤を硬化させる。この際、加熱処理を行う場合には、転写シート6の耐熱性を考慮して加熱温度を調整する必要があり、例えば80℃以上で加熱すればよい。
その後に、図7(D)のように、転写シート6を文字基板4から剥がす。文字部材2が配置されていない周辺部7Aは、転写シート6とともに文字基板4から剥がれる。
【0040】
従来では、転写シート6を剥がす際に、周辺部7Aが文字基板4に残り、良好な外観が得られない場合があった。そこで、残留した接着剤7を除去するために、洗剤を塗布したブラシや溶剤を含浸させた綿棒などで文字基板4を拭っていた。しかし、接着剤7は、粘着性を有しているので接着剤7が糸状に尾をひいてしまい文字基板4を汚してしまったり、文字部材2の配置がずれてしまったり、文字基板4に傷やシミが付くなどの不都合があった。
このような本発明によれば、転写シート6を剥がす際には接着剤7が硬化剤によって固体化しているので、周辺部7Aが文字基板4に粘着せず、良好な外観の文字板1が得られる。これにより洗剤などで拭き取る作業を省略でき、生産効率を向上させることができる。
また、転写シート6を剥がす際に文字部材2の外周部分で接着剤7が分離されやすく、文字部材2の外周部分に接着剤7がはみ出さないので、より一層外観を良好にできる。
さらに、この方法によれば、転写シート6を被せた状態で接着剤7を硬化させるので、ゴミの粘着をより確実に防止できる。
【0041】
文字部材2は電鋳めっきによって形成されていたが、これに限らず、例えば塗料入れや印刷によって形成されていてもよい。塗料入れによって文字部材2を形成する場合には、本実施形態におけるめっき形成部9Aに塗料を入れ、これを固めることによって形成する。この場合には、基材9に設けるレジスト剤10の厚さを電鋳めっきの場合よりも厚く、例えば150μm以上に設定すればよい。また、この場合には、レジスト剤10は非導電性である必要はなく、基材9も導電性の材料でなくてよい。ここで、レジスト剤10を厚く構成するためには、フィルムを重ねて形成することが望ましい。
また、印刷によって文字部材2を形成する場合には、レジスト剤10を形成する必要はなく、基材9は、導電性の材料である必要はない。
【0042】
文字板1の製造工程における各工程は、手作業に限らず、機械等で作業を自動化してもよい。例えば、転写シート6の文字部材2への貼付工程は、転写シート6をロール状に供給して自動で文字部材2に貼り付けてもよい。また、文字部材2を文字基板4へ貼り付ける際にもロボット等によって自動に行ってもよい。
【0043】
文字シール3は、平面状のシート状に形成されたが、文字シール3の形状はこれに限定されない。例えば、曲面に文字部材2を貼るときには、その曲面に合わせた曲面を有する文字シール3を形成すればよい。このようにすれば、形成された文字部材2が曲面に合わせて良好に接着される。
【0044】
マスキング層12は、必ずしも設けなくても文字部材2を形成することができる。ただし、マスキング層12を設けた場合には、当該部分にめっきが形成されないので、めっきの使用量を節約できる。ゆえに、文字板1の肉盛りめっきを施すべき部分の電流密度を大きくすることが可能となるので、文字部材2の肉盛りめっきの厚さを増して、立体的な装飾性を向上することができる。
【0045】
粘着剤は、前述のような溶剤性粘着型、水溶性粘着型、UV粘着型に限らず、所望の粘着力を得ることができるものであればよい。また、硬化剤は、前述のようなUV硬化型、熱硬化型に限らず、不可逆的に接着剤7を固体状態の相転移させることができるものであればよい。
【0046】
接着剤7は、転写シート6全面に塗布されていたが、これに限らず、例えば何らかの方法により文字部材2の接着面2Aのみに塗布されていてもよい。この場合では、接着面2Aのみに接着剤7を塗布するので、転写シート6を剥がした際に、接着剤7が文字基板4上の文字部材2が配置されない部分に残ることがない。よって、文字板1の外観が良好になる。また、必要な部分のみに接着剤7が塗布されているので、接着剤7の使用量を節約できる。
【0047】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dial, a dial manufacturing method, and a timepiece. More specifically, the present invention relates to a dial having a decorative member such as a character on the surface, a method of manufacturing the dial, and a timepiece having the dial.
[0002]
[Background Art]
BACKGROUND ART Conventionally, as a method of decorating decorative parts such as characters on a timepiece dial, a method of attaching a decorative part to a dial with an adhesive has been known. According to this method, first, an adhesive is applied to the back of the decorative component, a release paper is attached to the adhesive, and a transfer sheet is attached to the decorative component to form a three-layered seal. When attaching the decorative component to the dial, the release paper is peeled off, the adhesive is attached to the dial, and then the transfer sheet is peeled off to transfer the decorative component to the dial. At this time, the adhesive is usually a water-soluble adhesive that adjusts the adhesiveness by evaporating water, a solvent-based adhesive that adjusts the adhesiveness by volatilizing a solvent, or irradiated with ultraviolet (UV). Those that adjust the adhesiveness are used.
[0003]
[Problems to be solved by the invention]
However, since the adhesive layer is exposed on the outer peripheral part of the decorative component after the transfer sheet is peeled off, fine dust remains on the adhesive and impairs the appearance of the dial. In some cases. In order to remove such minute dust, a method of applying a solvent to a thin cotton swab or the like and wiping it off may be considered. However, in this method, not only the number of working steps is increased, but also the dial may be stained because the solvent causes the tail of the adhesive to form a thread. Alternatively, there is an inconvenience that the position of the decorative component is shifted due to the movement of the adhesive when touched with a cotton swab or the like. Also, if the solvent is not completely removed after wiping, it may cause stains.
A method of removing air by blowing air to the dial is also conceivable, but it is difficult to reliably remove dust adhered to the adhesive by this method.
[0004]
An object of the present invention is to provide a dial having a good appearance without dust adhering to an outer peripheral portion of a decorative component. Another object of the present invention is to provide a method for manufacturing a dial having a good appearance. Another object of the present invention is to provide a timepiece provided with a dial having a good appearance.
[0005]
[Means for Solving the Problems]
Therefore, the dial of the present invention has a character substrate and a decorative member having a decorative member bonded to the character substrate via the bonding portion, wherein the bonding portion has adhesive means having fluidity, Irreversible phase transition means for irreversibly changing the phase of the bonded portion from a fluid state to a solid state by solidification or hardening.
Here, solidification refers to solidifying the bonded portion by removing water or a solvent. Curing refers to solidification of the bonded portion by a polymerization reaction. Examples of the curing include photocuring for solidifying by irradiating ultraviolet (UV) or the like, and thermosetting for solidifying by heating or irradiation with heat rays. is there.
In the dial of this configuration, the decorative member is favorably adhered to the character substrate by the adhesive means constituting the adhesive portion. In addition, while maintaining good adhesive strength by the adhesive means, the entire bonded portion or the outer peripheral portion of the decorative member can be phase-transformed to a solid state by the irreversible phase transition means, so that fine dust adheres after the phase transition. The appearance of the dial is improved without sticking to the part.
Further, according to the dial having this configuration, unlike the related art, a step of wiping dust with a solvent or the like is not required, so that the manufacturing process is simplified.
[0006]
At this time, the adhesive means includes a solvent-based adhesive type that adjusts adhesiveness by volatilizing a solvent, a water-soluble adhesive type that adjusts adhesiveness by evaporating water, and irradiation of ultraviolet (UV). It is desirable to use one of the UV-adhesive types for adjusting the adhesiveness by using a UV-adhesive type.
In the dial of this configuration, the adhesive means can adjust the adhesiveness by performing a predetermined process, so that the dial is easily and reliably manufactured. Here, the predetermined treatment is, for example, in the case of a solvent-based pressure-sensitive adhesive or a water-soluble pressure-sensitive adhesive, the adhesive applied to the decorative member is left for a certain period of time, or the solvent is evaporated or water is evaporated by heating. Means to promote, for example. In the case of UV adhesive type adhesive means, it means that a predetermined amount of ultraviolet light (UV) is applied. Thereby, the adhesiveness of the bonding portion can be easily adjusted, and the decorative member is well bonded to the character substrate.
[0007]
In the dial of the present invention, the irreversible phase transition means is desirably a UV-curing type that cures by irradiating ultraviolet rays (UV) or a thermosetting type that cures by heating.
In the dial having this configuration, the adhesive portions can be solidified at a desired time by performing a predetermined process. For example, if this processing is performed in a state where the decorative member is bonded to the character substrate, the bonded portion can be solidified while maintaining a good adhesive force between the decorative member and the character substrate. Therefore, adhesion of dust to the outer peripheral portion of the decorative member is easily and reliably prevented. Here, the predetermined processing refers to irradiating a predetermined amount of ultraviolet light when using a UV-curable irreversible phase transition unit. When a thermosetting irreversible phase transition means is used, it means heating at a predetermined temperature. By these treatments, the bonded portion can be easily solidified.
[0008]
As described above, the method for manufacturing a dial has at least an adhesive portion on an adhesive surface of a decorative member, a release sheet attached to a side having the adhesive portion of the decorative member, and a side on which the release sheet of the decorative member is provided. A method for manufacturing a dial using a sheet-like seal having a transfer sheet attached to the opposite side, wherein the adhesive portion of the sheet-like seal is solidified or cured by an adhesive means having fluidity in advance. Irreversible phase transition means for irreversibly changing the state of the adhesive portion from the fluid state to the solid state, and peeling off the release sheet of the sheet-like seal, peeling off the release sheet, and removing the surface where the adhesive portion is exposed. After sticking to the character substrate by the adhesive means and peeling off the transfer sheet from the decorative member attached to the character substrate, the adhesive part between the character substrate and the decorative member is irreversibly changed from the fluid state to the solid state. And wherein the causing the transfer.
[0009]
In the method for manufacturing a dial according to this method, the decorative member formed on the sheet-shaped seal is transferred to the character substrate by the adhesive force of the adhesive portion. Then, since the bonded portion is irreversibly changed from the fluid state to the solid state, the decorative member is fixed to the character substrate while maintaining a good adhesive force. Since the bonded portion has changed into a solid state, fine dust does not adhere to the outer peripheral portion of the decorative member, and the appearance is improved. In addition, unlike the related art, there is no need to wipe off dust with a solvent or the like, and the manufacturing process is simplified.
[0010]
Alternatively, in the method for manufacturing a dial as described above, at least an adhesive portion is provided on an adhesive surface of the decorative member, a release sheet is attached to a side of the decorative member having the adhesive portion, and a release sheet of the decorative member is provided. A method for manufacturing a dial using a sheet-like seal having a transfer sheet attached to the opposite side to the opposite side, wherein an adhesive portion of the sheet-like seal is solidified with an adhesive means having fluidity in advance, or Irreversible phase transition means for irreversibly changing the state of the bonded portion from the fluid state to the solid state by curing, peeling off the release sheet of the sheet-like seal, peeling off the release sheet, and exposing the bonded portion. Affixing the surface to the character substrate with an adhesive means, and after irreversibly changing the bonded portion between the character substrate and the decorative member from the fluid state to the solid state, removing the transfer sheet from the decorative member. And butterflies.
[0011]
In the method for manufacturing a dial according to this method, the decorative member formed on the sheet-shaped seal is transferred to the character substrate by the adhesive force of the bonding portion. Thereafter, before peeling off the transfer sheet, the bonded portion is irreversibly phase-transformed from a fluid state to a solid state. In other words, the bonded portion undergoes a phase transition to a solid state while the decorative member is protected by the transfer sheet. Therefore, adhesion of dust is more reliably prevented.
Further, for example, the adhesive portion may be continuously provided not only on the adhesive surface of the decorative member but also on the transfer sheet where the decorative member is not disposed. In this case, in particular, since the transfer sheet is peeled off after the bonding portion has changed to a solid state, the bonding portion of the portion where the decorative member is not disposed does not stick to the character substrate, and an extra bonding portion is formed on the character substrate. Does not remain. Therefore, the appearance is improved.
Further, in the related art, when the transfer sheet is peeled off, the adhesive portion is difficult to be separated at the outer peripheral portion of the decorative member, and may remain on the outer peripheral portion of the decorative member. In the method for manufacturing a dial according to the present invention, when the transfer sheet is peeled off, the bonded portion has already undergone a phase transition to a solid state. Therefore, the adhesive portion is not extended and is easily separated at the outer peripheral portion of the decorative member, and the adhesive portion does not protrude from the outer peripheral portion of the decorative member. Therefore, the appearance is excellent. In particular, when a UV-curable type transition means is used as the irreversible phase transition means, the adhesive portion disposed between the decorative member and the character substrate is hardly irradiated with ultraviolet rays, and thus becomes semi-cured. On the other hand, the bonded portion where the other decorative members are not disposed is completely cured. Therefore, when peeling off the transfer sheet, the adhesive portion is favorably separated at the outer peripheral portion of the decorative member.
[0012]
In addition, such a dial is suitable for use as a dial of a timepiece because it has no sticking of dust and has a good appearance as described above.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a partial sectional view of a character seal 3 used for manufacturing the dial 1 (see FIG. 6) according to the present embodiment. The character seal 3 is formed by forming a character member 2 as a decorative member to be decorated on a character substrate 4 (see FIG. 6) in a sheet shape.
[0014]
In FIG. 1, a character member 2 is formed in a shape of a character or a number (a number in the present embodiment), and a plurality of character members 2 are provided so as to be adhered to a character substrate 4. The surface of the character member 2 to be bonded to the character substrate 4 is a flat bonding surface 2A. The surface opposite to the bonding surface 2A is a convex portion 2B having an arc-shaped cross section that can be visually recognized from the outside when bonded to the character substrate 4.
The character member 2 is formed by electroforming plating, and is made of a material such as nickel (Ni), copper (Cu), gold (Au), silver (Ag) or the like so as to reduce plating stress after the formation.
[0015]
A transparent film-like transfer sheet 6 is adhered to the convex portion 2B of the character member 2 so as to follow the shape of the convex portion 2B. An adhesive (not shown) is applied to the surface of the transfer sheet 6 on the side where the character member 2 is in close contact, and is adhered to the character member 2 with an appropriate adhesive force. The transfer sheet 6 prevents the character members 2 from being displaced from each other when transferring the character members 2 to the character substrate 4, and also serves as a protection sheet for the character members 2 so that the character members 2 are not damaged. .
Here, the material of the transfer sheet 6 may be a non-breathable material that can be easily peeled off and adheres to the character member 2, and for example, a soft film such as polyethylene or polypropylene can be used.
[0016]
An adhesive 7 is applied to the adhesive surface 2 </ b> A of the character member 2 and the transfer sheet 6 where the character member 2 is not disposed, as an adhesive portion for bonding these to the character substrate 4. The adhesive 7 includes a pressure-sensitive adhesive as a pressure-sensitive adhesive having fluidity, and a curing agent as an irreversible phase transition means for irreversibly changing the phase of the adhesive 7 from a fluid state to a solid state by solidification or curing. It is configured.
Here, as the pressure-sensitive adhesive, for example, a solvent-based pressure-sensitive adhesive for adjusting the tackiness by volatilizing a solvent, a water-soluble pressure-sensitive adhesive for adjusting the tackiness by evaporating water, or irradiation with ultraviolet (UV) light UV-adhesive type for adjusting the adhesiveness can be adopted. For example, a urethane-based resin or the like can be used as the solvent-based adhesive type, and an acrylic resin or the like can be used as the water-soluble adhesive type or the UV-based adhesive type.
As the curing agent, for example, a thermosetting type that cures by heating, a UV curing type that cures by irradiating ultraviolet rays, and the like can be adopted. As the thermosetting type, for example, an epoxy resin can be adopted, and as the UV curing type, an acrylic resin can be adopted.
[0017]
The selection of the materials of the pressure-sensitive adhesive and the curing agent, the mixing ratio thereof, and the like are appropriately determined in consideration of the compatibility of the two materials, the required adhesive strength, and the like. That is, for example, when a solvent-based adhesive type and a UV curable type are combined, a urethane-based resin and an acrylic-based resin are mixed at an appropriate mixing ratio. Depending on the compounding ratio, the adhesive strength is improved or lowered when the UV curing type is cured. Therefore, the compounding ratio and the material are used when it is desired to obtain a strong adhesive force for improving the durability or when it is desired to set the adhesive force to a relatively small value in consideration of the easiness of a product model change. It is appropriately selected according to the purpose.
[0018]
A release sheet 8 is provided on the adhesive surface 2A side of the character member 2 so as to be in close contact with the adhesive 7. The material of the release sheet 8 is made of, for example, paper whose surface is treated with a fluororesin or resin film, which is non-breathable and has good releasability from the adhesive 7. The release sheet 8 prevents adhesion of dust to the adhesive 7 and evaporation of a solvent of the adhesive 7 or evaporation of moisture.
[0019]
Such a character seal 3 is manufactured by, for example, arranging a plurality of character seals 3 vertically and horizontally to form a character sheet 13 (see FIG. 4) and cutting the same. Hereinafter, a method for manufacturing the character seal 3 will be described.
[0020]
The character seal 3 is manufactured by forming the character member 2 manufactured by electroforming plating into a sheet-like seal. Therefore, first, a method of manufacturing the character member 2 will be described.
FIG. 2 shows a manufacturing process for manufacturing the character member 2 by electroforming plating. To manufacture the character member 2, first, as shown in FIGS. 2A and 2B, a resist agent 10 is applied to one surface of a plate-shaped base material 9.
It is preferable that the base material 9 be a mirror-finished surface with a smooth surface finish so that the plating thickness is uniform. If the surface of the substrate 9 is not smooth, copper plating may be applied as a base plating to smooth the surface. The material of the base material 9 may be any material having conductivity, and for example, nickel silver (NS), copper (Cu), steel, or the like can be used. Alternatively, a conductive film treatment may be applied to the surface of a non-conductive material. The size of the base member 9 may be any size as long as a large number of character seals 3 are arranged in rows and columns. Also, the thickness of the base material 9 may be a thickness having good strength with good workability and handleability, and is appropriately determined in consideration of the material and size of the base material 9.
[0021]
The resist agent 10 is non-conductive, preferably an exposure-development type, and is formed on the surface of the base material 9 by a method such as printing, painting, or film sticking. The resist agent 10 forms an acid-resistant, non-conductive layer on one surface of the substrate 9. The thickness of the resist agent 10 is appropriately determined in consideration of the thickness and thickness of the character member 2. Generally, if the thickness is 10 μm or more, a good three-dimensional character member 2 can be obtained. When thick plating is desired, the thickness of the resist agent 10 needs to be increased in order to secure the dimensional accuracy of the character member 2. In this case, the desired thickness may be set by superimposing a film-like resist agent.
[0022]
Next, as shown in FIG. 2C, a negative 11 having the shape of the character member 2 is created. Then, the negative 11 is placed on the surface of the base material 9 on which the resist agent 10 has been applied, and ultraviolet exposure E is performed. Here, the shape of the negative 11 is a dimension in which dimensional errors generated in various processes are included as correction values in advance so that the shape of the character member 2 formed at the time of performing electroforming plating has a desired dimension. create.
[0023]
Thereafter, the base material 9 subjected to the ultraviolet exposure E is developed by a general alkali developing method or a solvent method as shown in FIG. 2 (D). Then, the resist agent 10 is removed along the shape of the negative 11. As a result, a plated portion 9A in which the conductive base material 9 is exposed is formed in substantially the same shape as the character member 2.
Thereafter, as shown in FIG. 2E, a masking layer 12 is formed on the surface (back surface) of the base material 9 opposite to the plating formation portion 9A. The masking layer 12 is provided for preventing plating from being formed on the back surface of the conductive base material 9 when performing electroforming plating. The masking layer 12 is made of a non-conductive material, and is formed by, for example, applying a paint such as a synthetic resin by painting or screen printing, or attaching a film made of a synthetic resin.
[0024]
Such a base material 9 is subjected to electroforming plating as shown in FIG. At this time, it is necessary to ensure the conductivity of the base material 9 and to make it easier for the character member 2 formed by electroforming plating to be separated from the base material 9. Therefore, an activation process and a passivation process are performed on the base material 9 before performing the electroforming plating.
Thereafter, electroforming plating is performed on the substrate 9 in an electroforming plating tank. Electroforming plating is performed under general electroplating conditions. The material of the plating solution is the material used for the character member 2 as described above. The thickness of the electroformed plating is appropriately set so as to obtain a desired three-dimensional appearance. By this electroforming plating, a plating solution is filled in the plating forming portion 9A on the base material 9, and a part of the plating forming portion 9A is protruded from the plating forming portion 9A to form a convex portion 2B in a build-up shape.
After the electroforming plating, the character member 2 formed to have a desired thickness may be subjected to various post-treatments so as to have a variation in color tone and finish. Such post-processing includes, for example, Au plating, Rh plating, black Ni plating, Sn plating, black Cr plating, matte Ni plating, and the like. Alternatively, it may be colored by spray coating, electrodeposition coating or the like.
[0025]
Next, a method of forming the character member 2 formed as described above on the character sheet 13 will be described.
FIG. 3 shows a manufacturing process of the character sheet 13. As shown in FIG. 3A, first, the transfer sheet 6 is brought into close contact with the base material 9 including the convex portions 2B of the character member 2 formed by electroforming plating. In this state, the transfer sheet 6 is peeled off from the substrate 9 as shown in FIG. Since the adhesive is applied to the transfer sheet 6 as described above, the protrusions 2B adhere to the transfer sheet 6. On the other hand, the base material 9 is treated so that the character member 2 is easily peeled off. Here, the adhesive force between the base member 9 and the character member 2 is set to be weaker than the adhesive force between the character member 2 and the transfer sheet 6. Therefore, the character member 2 is transferred from the base material 9 to the transfer sheet 6 as the transfer sheet 6 is peeled off.
[0026]
Next, as shown in FIG. 3C, an adhesive 7 is applied to the bonding surface 2A of the character member 2 by a method such as spraying or screen printing. The thickness of the adhesive 7 is appropriately set in consideration of the shapes, dimensions, surface roughness, and the like of the character member 2 and the character substrate 4, and is set to, for example, 20 μm or more. In the case of the screen printing method, the coating thickness can be set according to the viscosity of the adhesive 7 and the roughness of the screen mesh, and a smooth surface with a uniform thickness can be obtained. Since the adhesive 7 is applied to the entire surface of the transfer sheet 6, the adhesive 7 is also applied to a portion of the transfer sheet 6 where the character member 2 is not provided.
At this time, the liquid adhesive 7 having fluidity is applied in consideration of the simplicity of the operation. Then, the adhesive 7 is subjected to a predetermined treatment to adjust the adhesiveness. Here, the predetermined treatment is, for example, in the case of an adhesive 7 including a solvent-based adhesive or a water-soluble adhesive, after applying the adhesive 7 to the transfer sheet 6, the solvent is volatilized or water is removed by leaving the adhesive 7 to stand. Evaporate to adjust tack. Alternatively, by heating the adhesive 7, the evaporation of the solvent and the evaporation of the water may be promoted. In this case, a predetermined temperature may be set in consideration of the heat-resistant temperature of the transfer sheet 6 and, for example, heating may be performed at 100 ° C. or less.
[0027]
After the adhesive 7 has tackiness, as shown in FIG. 3 (D), a release sheet 8 is attached to the surface to which the adhesive 7 is applied.
By the above method, the character member 2 has the adhesive 7 on the bonding surface 2A and is formed on the character sheet 13 covered on both sides with the transfer sheet 6 and the release sheet 8. As shown in FIG. 4, the character sheet 13 has a large number of character stickers 3 arranged vertically and horizontally continuously. Therefore, when using the character seal 3, the character sheet 13 may be cut as needed in accordance with the supply form of the character sheet 13. When cutting the character sheet 13, the character sheet 13 is cut out, for example, using a cutting machine or the like, or by hand.
[0028]
A method of manufacturing the dial 1 by attaching the thus formed character seal 3 to the character substrate 4 will be described.
First, in order to improve the adhesion to the character member 2, the stain on the character substrate 4 is removed in advance by washing or the like. Here, although not shown, the character substrate 4 is a substantially square plate-shaped member, and includes a dial forming portion formed in the center and a grip portion formed around the dial forming portion. A groove or the like is formed between the dial forming portion and the grip portion, and both are easily cut. In addition, a positioning hole for positioning when attaching the character member 2 is provided in the grip portion.
Such a character substrate 4 is fixed to a sticking jig in order to position the character substrate 4 with respect to the character member 2. The sticking jig is provided with pins for positioning the character substrate 4. The positioning hole of the character member 2 is aligned with this pin to perform positioning. In the case where the character substrate 4 is composed of only the dial forming portion without the grip portion, the positioning may be performed by providing a notch or the like on the outer periphery of the character substrate 4.
[0029]
On the other hand, the release sheet 8 of one character seal 3 cut out from the character sheet 13 is peeled off as shown in FIG. Here, since the adhesive force between the release sheet 8 and the adhesive 7 is set to be weaker than the adhesive force between the adhesive 7 and the transfer sheet 6, the character member 2 and the adhesive 7 remains on the transfer sheet 6.
Next, the release sheet 8 is peeled off, and the surface where the adhesive 7 is exposed is attached to the character substrate 4 as shown in FIG. Here, as shown in FIG. 1, at both ends outside the region where the character member 2 is arranged, positioning portions 5 for defining the attachment position with respect to the character substrate 4 are provided. The positioning portion 5 has a rod-shaped portion 5A arranged in parallel with each other and a positioning hole 5B formed at the center of the rod-shaped portion 5A in the longitudinal direction. Therefore, the character member 2 is positioned with respect to the character substrate 4 by aligning the positioning hole 5B of the positioning part 5 with another pin provided on the attaching jig. After the character members 2 are arranged at predetermined positions on the character substrate 4, pressure is applied from above the transfer sheet 6 to ensure that these character members 2 adhere to the character substrate 4.
[0030]
Next, as shown in FIG. 5C, the transfer sheet 6 is peeled off. At this time, the character member 2 is pressed and adheres to the character substrate 4. When the transfer sheet 6 is peeled off while pressing the character member 2, the character member 2 is adhered to the character substrate 4 and remains. On the other hand, the peripheral portion 7A, which is the adhesive 7 in the portion where the character member 2 is not provided, is adhered to the transfer sheet 6 and peeled off together, and separated from the character lower portion 7B, which is the adhesive 7 between the character member 2 and the character substrate 4. Is done. Therefore, in this case, it is desirable that the adhesive strength between the transfer sheet 6 and the adhesive 7 is set to a value larger than the adhesive strength between the adhesive 7 and the character substrate 4. It is desirable that the adhesive force between the adhesive 7 and the character substrate 4 be set to a value larger than the adhesive force between the character member 2 and the transfer sheet 6. Under such conditions, the peripheral portion 7A peels off well with the transfer sheet 6. Even when it is difficult to satisfy such a condition, the character sheet 2 can be peeled off while pressing the character member 2, so that the character member 2 can be left on the character substrate 4 and the peripheral portion 7A can be peeled off together with the transfer sheet 6. .
[0031]
In such a state, as shown in FIG. 5D, the adhesive 7 irreversibly undergoes a phase transition from a fluid state to a solid state, that is, solidifies. The method of solidification differs depending on the curing agent used. For example, when a thermosetting curing agent is used, the character substrate 4 to which the character member 2 is adhered is heated. The temperature of the heating F is set in consideration of the material of the curing agent and the material of the character member 2 and the character substrate 4, and is heated at, for example, 120 ° C. or more. At this time, irradiation with heat rays such as infrared rays and far infrared rays may be used together with the heating F. For example, when a UV-curable curing agent is used, a predetermined amount of ultraviolet light F is irradiated toward the adhesive 7. The amount of the ultraviolet light F varies depending on the material of the UV-curable curing agent, but is generally 800 mj / cm. 2 The setting is made as described above.
When a UV adhesive type is used as the adhesive and a UV curable type is used as the curing agent, the adhesiveness is adjusted by adjusting the UV illuminance, and photocuring is performed later. In this case, the UV curing type generally requires more illuminance than the UV adhesive type, for example, 150 mW / cm. 2 Light curing is performed with the above illuminance.
When a UV curing type curing agent is used, the curing agent on the outer peripheral portion of the character member 2 is cured by irradiation with UV. At this time, depending on the shape of the character member 2, the curing agent inside may be covered by the character member 2 and may not be cured. Even in such a case, the inner peripheral portion of the character lower portion 7B adheres well due to the adhesive force of the adhesive, and the outer peripheral portion of the character lower portion 7B surely hardens.
[0032]
By cutting the dial plate forming portion of the character substrate 4 to which the character member 2 is stuck by such a method along a groove formed between the dial member and the grip portion, a character as shown in FIG. A plate 1 is formed. In the case of the character substrate 4 having no grip portion, such a cutting step is not required.
[0033]
According to the above embodiment, the following effects can be obtained.
Since the adhesive 7 is provided with a pressure-sensitive adhesive and a curing agent, it is possible to obtain tackiness and curability at a desired time. That is, when the character member 2 is attached to the character substrate 4, the adhesiveness is adjusted, so that both can be satisfactorily adhered. Further, since the adhesive 7 is cured by the curing agent after attaching the character member 2, fine dust does not adhere to the outer peripheral portion of the character member 2. Even when minute dust adheres to the outer peripheral portion of the character member 2, it can be easily removed by blowing air or the like. Therefore, the appearance can be improved. Even when a UV-curable curing agent is used as the curing agent, since the outer peripheral portion of the character lower part 7B is surely cured by UV irradiation, fine dust does not stick and the appearance can be improved. Since the inside of the character lower part 7B is in a semi-cured state, it can be satisfactorily adhered by the adhesive.
[0034]
Further, conventionally, dust attached to the outer peripheral portion of the character member 2 has been removed with a cotton swab impregnated with a solvent. However, according to the present embodiment, the adhesion of minute dust is prevented, and such work is not performed. It becomes unnecessary. Therefore, the manufacturing process of the dial 1 can be simplified. Further, since the arrangement of the character member 2 is not displaced by the operation of wiping with the solvent, and the stain is not attached to the character substrate 4, defective products can be reduced and the yield can be improved.
[0035]
With a conventional adhesive, the adhesive has fluidity even after the product is completed, so that when an external force is applied, the position of the character member 2 may move or be removed. However, according to the present embodiment, since the adhesive 7 is cured, the character member 2 can be securely fixed to the character substrate 4.
[0036]
As the pressure-sensitive adhesive of the adhesive 7, a solvent-based pressure-sensitive adhesive, a water-soluble pressure-sensitive adhesive, a UV-sensitive pressure-sensitive adhesive, or the like is used. be able to.
Moreover, since the curing agent of the adhesive 7 is a UV-curing type, a thermosetting type, or the like, by performing the above-described processing, the adhesive 7 can be surely cured at a desired time.
[0037]
If such a dial 1 is applied to a timepiece, adhesion of minute dust can be prevented, and the appearance can be improved.
[0038]
It should be noted that the present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved.
For example, in the above embodiment, all the character members 2 arranged on the dial 1 are formed on one character seal 3, but the present invention is not limited to this. For example, one character member 2 may be formed as one character seal 3. Alternatively, when character members 2 of different colors or different materials are arranged on one dial 1, a plurality of character seals 3 may be formed by colors or materials.
The character member 2 is a numeral, but is not limited thereto, and may have any shape such as a character, a mark, a maker name, a logo of a product name, notes, and other decorative patterns.
Furthermore, the dial 1 is not limited to the one that displays the current time, but may be a date wheel that displays the day, a day wheel that displays the day of the week, or the like.
[0039]
When the character member 2 is attached to the character substrate 4, in the present embodiment, the adhesive 7 is solidified after the transfer sheet 6 is peeled from the character substrate 4, but may be solidified before the transfer sheet 6 is peeled. Good.
That is, as shown in FIG. 7, after the character member 2 is attached to the character substrate 4 in (B), as shown in FIG. 7 (C), heating, heating, and heating are performed according to the material of the curing agent. A combination of irradiation and UV irradiation are performed to cure the curing agent. At this time, when performing the heat treatment, it is necessary to adjust the heating temperature in consideration of the heat resistance of the transfer sheet 6, and for example, the heating may be performed at 80 ° C. or more.
Thereafter, as shown in FIG. 7D, the transfer sheet 6 is peeled off from the character substrate 4. The peripheral portion 7A where the character member 2 is not arranged is peeled off from the character substrate 4 together with the transfer sheet 6.
[0040]
Conventionally, when the transfer sheet 6 is peeled off, the peripheral portion 7A remains on the character substrate 4, and a good appearance may not be obtained. In order to remove the remaining adhesive 7, the character substrate 4 is wiped with a brush coated with a detergent or a cotton swab impregnated with a solvent. However, since the adhesive 7 has tackiness, the adhesive 7 has a tail like a thread and stains the character substrate 4, the arrangement of the character member 2 is displaced, or the character substrate 4 There were inconveniences such as scratches and spots.
According to the present invention, since the adhesive 7 is solidified by the curing agent when the transfer sheet 6 is peeled off, the peripheral portion 7A does not adhere to the character substrate 4, and the dial 1 having a good appearance can be obtained. can get. Thereby, the work of wiping with a detergent or the like can be omitted, and the production efficiency can be improved.
Further, when peeling off the transfer sheet 6, the adhesive 7 is easily separated at the outer peripheral portion of the character member 2, and the adhesive 7 does not protrude to the outer peripheral portion of the character member 2, so that the appearance can be further improved.
Further, according to this method, the adhesive 7 is cured while the transfer sheet 6 is covered, so that adhesion of dust can be more reliably prevented.
[0041]
The character member 2 is formed by electroforming plating, but is not limited to this, and may be formed by, for example, coating with paint or printing. In the case where the character member 2 is formed by putting paint, the paint is put into the plating forming portion 9A in the present embodiment and formed by solidifying the paint. In this case, the thickness of the resist agent 10 provided on the base material 9 may be set to be thicker than in the case of electroforming plating, for example, 150 μm or more. In this case, the resist agent 10 does not need to be non-conductive, and the base material 9 need not be a conductive material. Here, in order to configure the resist agent 10 to be thick, it is desirable to form the film by overlapping.
When forming the character member 2 by printing, it is not necessary to form the resist agent 10, and the base material 9 does not need to be a conductive material.
[0042]
Each step in the manufacturing process of the dial 1 is not limited to a manual operation, and the operation may be automated by a machine or the like. For example, in the step of attaching the transfer sheet 6 to the character member 2, the transfer sheet 6 may be supplied in a roll shape and automatically attached to the character member 2. Also, when the character member 2 is attached to the character substrate 4, it may be automatically performed by a robot or the like.
[0043]
Although the character seal 3 is formed in a flat sheet shape, the shape of the character seal 3 is not limited to this. For example, when attaching the character member 2 to a curved surface, a character seal 3 having a curved surface matching the curved surface may be formed. In this way, the formed character member 2 is properly bonded to the curved surface.
[0044]
The character member 2 can be formed without necessarily providing the masking layer 12. However, when the masking layer 12 is provided, no plating is formed on the portion, so that the amount of plating used can be saved. Therefore, it is possible to increase the current density of the portion of the dial 1 where the overlay plating is to be performed, so that it is possible to increase the thickness of the overlay of the character member 2 and improve the three-dimensional decorativeness. it can.
[0045]
The pressure-sensitive adhesive is not limited to the solvent-based pressure-sensitive adhesive, the water-soluble pressure-sensitive adhesive, and the UV pressure-sensitive adhesive as described above, and may be any as long as it can obtain a desired pressure. The curing agent is not limited to the UV-curing type and the thermosetting type as described above, and may be any as long as it can irreversibly cause the adhesive 7 to undergo a solid-state phase transition.
[0046]
The adhesive 7 is applied to the entire surface of the transfer sheet 6, but is not limited to this, and may be applied to only the adhesive surface 2A of the character member 2 by, for example, some method. In this case, since the adhesive 7 is applied only to the adhesive surface 2A, when the transfer sheet 6 is peeled off, the adhesive 7 does not remain on the portion of the character substrate 4 where the character member 2 is not arranged. Therefore, the appearance of the dial 1 becomes good. Further, since the adhesive 7 is applied only to the necessary portions, the amount of the adhesive 7 used can be reduced.
[0047]
