Description
これによれば、移動方向が長辺方向と交差しているため、移動方向が長辺方向に平行な場合に比べて、押圧面を覆うシート材をスライドさせる際のシート材の移動距離が短くなる。これに伴い、移動方向が長辺方向に平行な場合に比べてシート材の交換に要する時間を短くすることができる。したがって、溶着装置の運転効率をさらに向上できる。
以下、溶着装置、及び当該溶着装置を用いた電極ユニットの製造方法の第1実施形態について説明する。
図1及び図2に示すように、電極ユニット10は、電極板11と、第1樹脂部20と、第2樹脂部30と、を備える。
ワークとしての電極板11は、バイポーラ型の電極である。電極板11は、集電体12と、第1活物質層16と、第2活物質層17と、を備える。
集電体12は、金属箔により構成される。集電体12は、例えば、銅箔、アルミニウム箔、チタン箔、もしくはニッケル箔である。機械的強度を確保する観点から、集電体12は、ステンレス鋼箔であってもよい。ステンレス鋼箔は、例えばJIS G 4305:2015にて規定されるSUS304、SUS316、SUS301等である。集電体12は、上記金属の合金箔や、複数の上記金属箔を一体化させたものであってもよい。集電体12の表面には、公知のメッキ処理や表面処理が施されていてもよい。集電体12の厚さは、例えば、1μm以上100μm以下、詳細には、5μm以上70μm以下である。集電体12の形状は、長方形のシート状である。集電体12は、その周縁を構成する4つの辺部12aを備える。これらの4つの辺部12aは、電極板11の周縁を構成するものでもある。すなわち、電極板11の形状もまた、長方形のシート状である。そして、電極板11は、その周縁を構成する4つの辺部12aを備えるともいえる。なお、電極板11は、前述のような形態に限られず、2枚の金属箔を単に重ねたものであってもよい。
集電体12は、主面13を備える。主面13は、集電体12の厚さ方向に垂直な面である。主面13は、第1主面14と、第2主面15と、を含む。第2主面15は、第1主面14に対して集電体12の厚さ方向において反対に位置している。
活物質層としての第1活物質層16は、正極活物質を含む。正極活物質は、リチウムイオン等の電荷担体を吸蔵及び放出可能である。正極活物質の例には、例えば複合酸化物、金属リチウム、及び硫黄等が含まれる。第1活物質層16は、必要に応じて導電助剤、結着剤、その他成分を含んでもよい。第1活物質層16は、第1主面14に一体に接着されている。第1活物質層16の厚さは、例えば2~150μmである。第1主面14に第1活物質層16を接着する方法としては、例えば、ロールコート法等の公知の方法が挙げられる。
活物質層としての第2活物質層17は、負極活物質を含む。負極活物質は、リチウムイオン等の電荷担体を吸蔵及び放出可能である。負極活物質の例には、例えば黒鉛、カーボン、金属化合物、リチウムと合金化可能な元素又はその化合物、及びホウ素添加炭素等が含まれる。第2活物質層17は、必要に応じて導電助剤、結着剤、その他成分を含有してよい。第2活物質層17の厚さは、例えば2~150μmである。第2活物質層17は、第2主面15に一体に接着されている。第2活物質層17の厚さは、例えば2~150μmである。第2主面15に第2活物質層17を接着する方法としては、例えば、ロールコート法等の公知の方法が挙げられる。
樹脂部としての第1樹脂部20は、枠状に形成されている。第1樹脂部20は、長方形状の枠体である。第1樹脂部20は、4つの第1樹脂辺部21を備える。第1樹脂辺部21は、四角柱状に形成されている。第1樹脂辺部21の端部は、互いに接続されている。各第1樹脂辺部21は、他の第1樹脂辺部21の1つと向かい合っている。
<第2樹脂部30>
樹脂部としての第2樹脂部30は、枠状に形成されている。第2樹脂部30は、長方形状の枠体である。第2樹脂部30は、4つの第2樹脂辺部31を備える。第2樹脂辺部31は、四角柱状に形成されている。第2樹脂辺部31の端部は、互いに接続されている。各第2樹脂辺部31は、他の第2樹脂辺部31の1つと向かい合っている。
このように構成された電極ユニット10が樹脂部20,30を介して積層されることで、蓄電モジュールBを構成する。積層された電極ユニット10のうち、互いに隣り合う一方の電極ユニット10の第1樹脂部20と、他方の電極ユニット10の第2樹脂部30の周縁14b,15bからはみ出している部分同士は、一体化されている。周縁14b,15bからはみ出している部分同士の一体化は、当該はみ出している部分同士の溶着や、接着部材による接着により行われ得る。接着部材としては、例えば樹脂部20,30で例示された樹脂材料等が用いられる。本実施形態の蓄電モジュールBは、バイポーラ型のリチウムイオン蓄電池である。蓄電モジュールBは、例えばフォークリフト、ハイブリッド自動車、電気自動車等の各種車両のバッテリに用いられる。
次に、図3~図6を用いて、溶着装置40の一例について説明する。溶着装置40は、ワークとしての電極板11への樹脂部20,30の押圧及び溶着を行うことで、電極ユニット10を製造する。言い換えれば、溶着装置40は、電極ユニット製造装置である。以下、説明の便宜上、溶着装置40がワークを押圧する方向を押圧方向Zという。本実施形態の電極ユニット10の製造方法では、2つの溶着装置40が用いられる。ここでは、溶着装置40の1つの構成について説明する。
各脚部42は、地面に対して下部台座41を支持する。
<シリンダユニット45>
シリンダユニット45は、シリンダボディ46と、シリンダロッド47と、を備える。
シリンダロッド47は、上部台座43を押圧方向Zに貫通している。シリンダロッド47は、シリンダボディ46に対して押圧方向Zに出没可能に構成されている。シリンダロッド47は、例えばサーボモータの駆動によってシリンダボディ46に対して出没する。
<押圧アセンブリ50a,50b>
2つの押圧アセンブリ50a,50bは、それぞれ下部台座41と上部台座43との間に配置されている。第1の押圧アセンブリ50aは、シリンダユニット45によって上部台座43に支持されている。第1の押圧アセンブリ50aは、シリンダロッド47に接続されている。第1の押圧アセンブリ50aは、シリンダユニット45の操作、例えばシリンダロッド47の出没、によって押圧方向Zに移動可能に構成されている。
以下、各押圧アセンブリ50a,50bの各部材の詳細について説明する。以下で用いる押圧アセンブリ50a,50bの部材は、特に明示がない限り、第1の押圧アセンブリ50aが備える部材として取り扱う。なお、第2の押圧アセンブリ50bが備える各部材は、第1の押圧アセンブリ50aが備えるものと同様である。そのため、第2の押圧アセンブリ50bが備える各部材は、第1の押圧アセンブリ50aのものと同一の部材番号を付すことで、説明を省略することがある。
押圧部51は、樹脂部20,30を押圧方向Zに押圧するシールバーである。本実施形態の押圧部51は、四角柱状である。押圧部51の長辺方向Xは、押圧方向Zに垂直である。押圧部51の短辺方向Yは、押圧方向Z及び長辺方向Xの両方に垂直である。押圧部51は、接続面51aと、押圧面51bと、2つの端面51cと、2つのガイド部51dと、を備える。
接続面51aは、押圧方向Zに垂直な2つの平面のうち、シリンダロッド47の先端が接続される面である。本実施形態の接続面51aは、押圧方向Zに垂直な長方形である。接続面51aの長辺は、長辺方向Xに延びている。接続面51aの短辺は、短辺方向Yに延びている。
押圧面51bは、押圧方向Zに垂直な平面のうち、押圧方向Zにおいて接続面51aの反対に位置する面である。本実施形態の押圧面51bは、長方形である。押圧面51bの長辺は、長辺方向Xに延びている。押圧面51bの短辺は、短辺方向Yに延びている。長辺方向Xは、押圧面51bの長辺が延びる方向ともいえる。また、短辺方向Yは、押圧面51bの短辺が延びる方向ともいえる。
2つの端面51cは、押圧部51の長辺方向Xの端に位置している。2つの端面51cは、押圧面51bの2つの短辺のそれぞれから押圧方向Zに延びている。
ガイド部51dは、押圧方向Zに延びている柱状の部材である。本実施形態のガイド部51dは円柱状である。ガイド部51dは、押圧部51の接続面51aに接続されている。
絶縁部52は、押圧面51bの絶縁性を保つ絶縁層である。絶縁部52は、押圧面51bを覆っている。本実施形態の絶縁部52は、シート状である。絶縁部52の材料は、例えばガラス繊維、セラミクスなど任意である。なお、絶縁部52は、押圧部51の絶縁性を高めるために、さらに端面51cを覆っていてもよい。
緩衝部53は、押圧部51に比べて弾性変形が容易な弾性体である。緩衝部53は、押圧面51bを覆っている。詳細には、緩衝部53は、絶縁部52を介して、押圧面51bを覆っている。緩衝部53は、押圧部51が樹脂部20,30を押圧している場合に弾性変形することにより、押圧部51が樹脂部20,30に印加する圧力のばらつきを抑制する。緩衝部53の材料は、例えば天然ゴム、フッ素ゴム、ウレタンゴムなど任意である。特に緩衝部53の材料としてシリコンゴムを用いる場合、押圧部51の絶縁性が向上する。また、緩衝部53の材料としてシリコンゴムを用いた場合、緩衝部53は、絶縁部52等の隣接する部材の滑り止めとしても機能する。
加熱部54は、樹脂部20,30の加熱を行う。本実施形態の加熱部54は、押圧部51と一体に設けられている。加熱部54は、電熱シート55と、2つの加熱電極56と、を備える。
電熱シート55は、シート状の抵抗体である。電熱シート55は、角U字状に形成されている。電熱シート55の熱膨張率は、緩衝部53の熱膨張率より高い。電熱シート55は、絶縁部52、及び緩衝部53を介して、押圧面51bを覆う。電熱シート55は、2つの端面51cを覆う。なお、端面51cと電熱シート55との間は、図示しない絶縁部材等により絶縁されている。
加熱電極56は、電熱シート55に電流を流すための電極である。2つの加熱電極56のそれぞれは、電熱シート55を介して2つの端面51cのそれぞれに配置されている。加熱電極56は、図示しない電源装置に接続されている。電源装置の電力は、加熱電極56を介して電熱シート55に流入する。これにより、電熱シート55が抵抗発熱する。加熱部54は、電熱シート55の抵抗発熱を利用して、樹脂部20,30の加熱を行う。
溶着抑制機構TFは、押圧部51及び押圧面51b上に配置されている部材などへの樹脂部20,30の溶着を抑制する機構である。押圧部51及び押圧面51b上に配置されている部材とは、例えば絶縁部52、緩衝部53、及び加熱部54である。溶着抑制機構TFは、シート材60と、移動機構70と、を備える。
シート材60は、電極板11に比べて樹脂部20,30から剥離しやすい。シート材60の樹脂部20,30に対する剥離強度は、電極板11の樹脂部20,30に対する剥離強度に比べて小さい。例えば、シート材60の樹脂部20,30に対する剥離強度は、電極板11の樹脂部20,30に対する剥離強度の0.5倍以下、好ましくは0.1倍以下、より好ましくは0.01倍以下である。シート材60は、ポリテトラフルオロエチレンなどのフッ素系化合物を含んでもよい。本実施形態のシート材60は、フッ素系化合物を含浸させたガラスクロスである。ガラスクロスはフッ素系化合物に比べて熱伝導率が高いガラス繊維からなる。そのため、シート材60をガラスクロスとすることで、加熱部54から樹脂部20,30への熱の伝達を好適に行うことができる。なお、シート材60は、ガラスクロスに限らず、例えば上記フッ素系化合物からなる樹脂をシート状に成形した樹脂シートであってもよい。
移動機構70は、巻出部71と、巻出調節部72と、一対の支持部73a,73bと、巻取調節部74と、巻取部75と、を備える。移動機構70は、シート材60を支持することで、シート材60が移動するシート移動経路L1を形成する。シート移動経路L1は、巻出部71から供給されたシート材60が辿る経路である。巻出部71から供給されたシート材60は、シート移動経路L1を、巻出調節部72→支持部73a,73b→巻取調節部74→巻取部75の順番で辿る。
巻出部71は、短辺方向Yに平行な回転軸を中心に回転可能なリールである。巻出部71には、シート材60が巻回されている。これにより、巻出部71は、シート材60の長手方向の端部の1つを支持している。巻出部71は、シート移動経路L1へのシート材60の供給源である。巻出部71は、シート移動経路L1における最上流に位置する。
巻出調節部72は、巻出部71から供給されるシート材60の搬送量を調整する。シート材60の搬送量は、例えばシート材60の長手方向の長さ、体積、移動距離などで表すことができる。説明の便宜上、シート材60の長手方向の長さを、単にシート材60の長さという。巻出調節部72は、第1巻出ガイドローラ72aと、第2巻出ガイドローラ72bと、巻出ダンサーローラ72cと、を備える。第1巻出ガイドローラ72a、第2巻出ガイドローラ72b、及び巻出ダンサーローラ72cは、それぞれ短辺方向Yに平行な回転軸を中心に回転可能である。
第1巻出ガイドローラ72a及び第2巻出ガイドローラ72bは、ともに巻出部71から長辺方向Xに離れて配置されている。第1巻出ガイドローラ72aは、第2巻出ガイドローラ72bと巻出部71との間に位置している。
巻出ダンサーローラ72cは、長辺方向Xにおける第1巻出ガイドローラ72aと第2巻出ガイドローラ72bとの中間点から、押圧方向Zに離れて配置されている。巻出ダンサーローラ72cは、第1巻出ガイドローラ72a及び第2巻出ガイドローラ72bよりも押圧方向Zにおいて押圧部51に近い位置にある。巻出ダンサーローラ72cは、少なくとも押圧方向Zに移動可能に構成されている。本実施形態では、巻出ダンサーローラ72cは、押圧方向Zに移動可能に構成されている。これにより、巻出ダンサーローラ72cは、第1巻出ガイドローラ72a及び第2巻出ガイドローラ72bに対する押圧方向Zの距離を調節できる。巻出ダンサーローラ72cは、後述する支持部73a,73bに支持された状態のシート材60のテンションを調節できる。
支持部73a,73bは、長辺方向Xに離れて配置されている。支持部73a,73bは、シート材60を長辺方向Xに架け渡している。これにより、シート材60は、支持部73a,73bによって押圧部51と樹脂部20,30との間に位置するように支持される。言い換えれば、支持部73a,73bは、シート材60が押圧部51と樹脂部20,30との間に位置するようシート材60を支持する。本実施形態では、支持部73a,73bは、シート材60が押圧面51bと接するようにシート材60を支持する。なお、シート材60が押圧面51bと接している状態には、シート材60が押圧面51bに直接的に接している状態に限られず、シート材60が絶縁部52、緩衝部53、加熱部54等の部材を介して押圧面51bに間接的に接している状態が含まれる。なお、シート材60と押圧面51bとが接している場合であっても、シート材60は押圧面51bに固定されていない。すなわち、シート材60は、押圧面51bに対して相対的に移動可能に構成されている。
第1支持部73aは、第2巻出ガイドローラ72bから押圧方向Zに離れて配置されている。第1支持部73aは、押圧部51から長辺方向Xに離れて配置されている。第1支持部73aの少なくとも一部は、端面51cの1つと長辺方向Xに向かい合っている。
第2支持部73bは、第1支持部73aから長辺方向Xに離れて配置されている。押圧方向Zからの平面視において、押圧部51、詳細には押圧面51bは、第1支持部73aと第2支持部73bとの間に位置している。第2支持部73bの少なくとも一部は、端面51cの1つと長辺方向Xに向かい合っている。第2支持部73bが向かい合う端面51cは、第1支持部73aが向かい合う端面51cと長辺方向Xにおいて反対に位置する。
巻取調節部74は、シート移動経路L1における支持部73a,73bより下流へのシート材60の搬送量を調整する。巻取調節部74は、第1巻取ガイドローラ74aと、第2巻取ガイドローラ74bと、巻取ダンサーローラ74cと、を備える。第1巻取ガイドローラ74a、第2巻取ガイドローラ74b、及び巻取ダンサーローラ74cは、それぞれ短辺方向Yに平行な回転軸を中心に回転可能である。
第1巻取ガイドローラ74a及び第2巻取ガイドローラ74bは、ともに巻取部75から長辺方向Xに離れて配置されている。第2巻取ガイドローラ74bは、第1巻取ガイドローラ74aと巻取部75との間に位置している。
巻取ダンサーローラ74cは、長辺方向Xにおける第1巻取ガイドローラ74aと第2巻取ガイドローラ74bとの中間点から、押圧方向Zに離れている。巻取ダンサーローラ74cは、第1巻取ガイドローラ74a及び第2巻取ガイドローラ74bよりも押圧方向Zにおいて押圧部51に近い位置にある。巻取ダンサーローラ74cは、少なくとも押圧方向Zに移動可能に構成されている。本実施形態では、巻取ダンサーローラ74cは、押圧方向Zに移動可能に構成されている。これにより、巻取ダンサーローラ74cは、第1巻取ガイドローラ74a及び第2巻取ガイドローラ74bに対する押圧方向Zの距離を調節できる。これにより、巻取ダンサーローラ74cは、支持部73a,73bに支持された状態のシート材60のテンションを調節できる。
巻取部75は、短辺方向Yに平行な回転軸を中心に回転可能なリールである。巻取部75は、巻出部71からシート移動経路L1に沿って供給されたシート材60を巻き取る。詳細には、巻取部75は、巻取調節部74から供給されたシート材60を巻き取る。巻取部75は、シート材60を巻き取ることにより、シート材60の長手方向の端部の1つを支持している。巻取部75は、シート移動経路L1からのシート材60の排出先である。巻取部75は、シート移動経路L1における最下流に位置する。
このように構成された溶着抑制機構TFでは、巻出部71から供給されたシート材60が、巻出調節部72、第1支持部73a、第2支持部73b、巻取調節部74を順番に経由して巻取部75に搬送される。このとき、移動機構70は、支持部73a,73bによって支持された状態のシート材60を移動方向Tにスライドさせる。移動方向Tとは、支持部73a,73bによって支持された状態のシート材60がスライドする方向である。具体的には、移動方向Tとは、第1支持部73aから第2支持部73bに向かう方向である。
このように構成された第1の押圧アセンブリ50aの押圧部51と第2の押圧アセンブリ50bの押圧部51とは、互いの支持部73a,73bによって支持されたそれぞれのシート材60を介して押圧方向Zに向かい合っている。第1の押圧アセンブリ50aのシート材60のうち支持部73a,73bによって支持されている領域と、第2の押圧アセンブリ50bのシート材60のうち支持部73a,73bによって支持されている領域と、は、押圧方向Zに離れて向かい合っている。第1の押圧アセンブリ50aのシート材60のうち支持部73a,73bによって支持されている領域と、第2の押圧アセンブリ50bのシート材60のうち支持部73a,73bによって支持されている領域と、の間には、樹脂部20,30が配置されている電極板11を配置可能である。
制御回路90は、プロセッサと、記憶部と、を備える。プロセッサとしては、例えば、CPU(Central Processing Unit)、GPU(Graphics Processing Unit)、又はDSP(Digital Signal Processor)が用いられる。記憶部は、RAM(Random Access Memory)及びROM(Read Only Memory)を含む。記憶部は、処理をプロセッサに実行させるように構成されたプログラムコード又は指令を格納している。記憶部、即ち、コンピュータ可読媒体は、汎用又は専用のコンピュータでアクセスできるあらゆる利用可能な媒体を含む。制御回路90は、ASIC(Application Specific Integrated Circuit)やFPGA(Field Programmable Gate Array)等のハードウェア回路によって構成されていてもよい。処理回路である制御回路90は、コンピュータプログラムに従って動作する1つ以上のプロセッサ、ASICやFPGA等の1つ以上のハードウェア回路、或いは、それらの組み合わせを含み得る。
次に、図5~図7を用いて、上記溶着装置40を用いた樹脂溶着ワークとしての電極ユニット10の製造方法について説明する。本実施形態では、2つの溶着装置40を用いて、電極ユニット10の製造が行われる。2つの溶着装置40の長辺方向Xは平行である。2つの溶着装置40の短辺方向Yは平行である。2つの溶着装置40の押圧方向Zは平行である。2つの溶着装置40は、短辺方向Yに離れて配置されている。
図7に示すように、制御回路90は、初期化工程S1において、変数kを0に設定する。変数kは、0以上の整数である。
次に、配置工程S2に進む。配置工程S2では、電極板11及び樹脂部20,30が、第1の押圧アセンブリ50aと第2の押圧アセンブリ50bとの間に配置される。本実施形態では、樹脂辺部21,31が辺部12aに沿って配置されている。樹脂部20,30の電極板11への配置は、例えば圧着等により予め実現されていてもよいし、後述する溶着工程S3にて樹脂部20,30の一部が電極板11に溶着されているものでもよい。樹脂部20,30の一部とは、例えば向かい合う2つの第1樹脂辺部21及び向かい合う2つの第2樹脂辺部31である。このとき、互いに向かい合う2つの第1樹脂辺部21が、それぞれ異なる溶着装置40における第1の押圧アセンブリ50aの押圧部51と押圧方向Zに向かい合う。同様に、互いに向かい合う2つの第2樹脂辺部31が、それぞれ異なる溶着装置40における第2の押圧アセンブリ50bの押圧部51と押圧方向Zに向かい合う。当該電極板11は、例えば図示しないロボットハンド等によって第1の押圧アセンブリ50a及び第2の押圧アセンブリ50bの間に配置される。
次に、溶着工程S3に進む。溶着工程S3において、制御回路90は、2つの溶着装置40を用いて樹脂部20,30を電極板11に溶着することで、電極ユニット10を製造する。本実施形態では、配置工程S2にて各押圧アセンブリ50a,50bの間に配置された樹脂辺部21,31が電極板11に溶着される。
次に制御回路90は、押圧部51を用いて、シート材60を介して、溶融した樹脂部20,30を押圧する。具体的には、制御回路90は、シリンダロッド47をシリンダボディ46から押圧方向Zへさらに突出させることで、押圧面51bにシート材60を介して樹脂辺部21,31を押圧させる。
図7に示すように、溶着工程S3の終了後、計数工程S4に進む。計数工程S4において、制御回路90は、変数kの値を1増やす。
次に移動判定工程S5に進む。移動判定工程S5において、制御回路90は、溶着工程S3が所定の回数行われたか否かを判定する。本実施形態では、制御回路90は、変数kが判定値Nと一致しているか否かを判定する。すなわち、移動判定工程S5における所定の回数とは判定値Nで表される回数である。判定値Nは、1以上の整数であれば任意である。判定値Nは、例えばシート材60の耐用回数以下であれば任意である。シート材60の耐用回数とは、例えば溶着工程S3の後にシート材60を樹脂部20,30から剥離できることを1回として、この1回を実行可能な回数である。判定値Nは、例えば耐用回数の0.001~1倍、好ましくは0.005~0.5倍、より好ましくは0.01~0.1倍の範囲に含まれる。
シート材60の劣化の要因の1つとしては、樹脂部20,30の押圧の際に、電極板11の加工痕、例えば辺部12aのバリ、がシート材60に干渉することが考えられる。辺部12aのバリは、例えば電極板11の母材をダイカッター等で切断することで電極板11を製造する際に生じる。このような電極板11の加工痕による劣化は、押圧部51に押圧される樹脂辺部21,31が延びる長辺方向Xに生じる。
一方、移動判定工程S5の判定結果が肯定の場合、すなわち変数kが判定値Nに達している場合、移動工程S6に進む。移動判定工程S5の判定結果が肯定の場合とは、溶着工程S3が所定の回数行われた場合である。したがって、移動工程S6は、溶着工程S3が1回以上行われた場合に行われる。移動工程S6は、溶着工程S3の後に行われる工程ともいえる。
なお、シート材60の移動距離は、樹脂部20,30の材料や形状、シート材60の材料や形状、及び溶着工程S3の具体的態様に応じて適宜設定すればよい。
以下、本実施形態の作用について説明する。
以下、本実施形態の効果について説明する。
(1-1)溶着装置40は、ワークとしての電極板11に樹脂部20,30を溶着させる。溶着装置40は、押圧部51と、一対の支持部73a,73bと、移動機構70と、を備える。支持部73a,73bは、移動方向Tに離れて配置される。また、支持部73a,73bは、シート材60が押圧面51bを押圧方向Zから覆うようにシート材60を支持する。移動機構70は、支持部73a,73bによって支持された状態のシート材60を移動方向Tにスライドさせる。
次に、溶着装置、及び当該溶着装置を用いた電極ユニットの製造方法の第2実施形態について説明する。なお、説明の便宜上、第2実施形態の構成のうち、第1実施形態と同様の構成については同一の部材番号を付すことによって説明を省略するとともに、異なる構成を説明する。
<巻出部71>
巻出部71は、長辺方向Xに平行な回転軸を中心に回転可能なリールである。下部台座41及び上部台座43に対する巻出部71の位置は、第1実施形態と同様である。
第1巻出ガイドローラ72a、第2巻出ガイドローラ72b、及び巻出ダンサーローラ72cは、それぞれ長辺方向Xに平行な回転軸を中心に回転可能である。
第1巻出ガイドローラ72a及び第2巻出ガイドローラ72bは、ともに巻出部71から短辺方向Yに離れて配置されている。
巻出ダンサーローラ72cは、短辺方向Yにおける第1巻出ガイドローラ72aと第2巻出ガイドローラ72bとの中間点から、押圧方向Zに離れて配置されている。
第1支持部73a及び第2支持部73bは、それぞれ長辺方向Xに平行な回転軸を中心に回転可能である。
第1巻取ガイドローラ74a、第2巻取ガイドローラ74b、及び巻取ダンサーローラ74cは、それぞれ長辺方向Xに平行な回転軸を中心に回転可能である。
<巻取ダンサーローラ74c>
巻取ダンサーローラ74cは、短辺方向Yにおける第1巻取ガイドローラ74aと第2巻取ガイドローラ74bとの中間点から、押圧方向Zに離れている。
巻取部75は、長辺方向Xに平行な回転軸を中心に回転可能なリールである。巻取部75は、巻出部71と短辺方向Yに離れて配置されている。
第1支持部73aと第2支持部73bとは、短辺方向Yに離れて配置されている。したがって、本実施形態における移動方向Tは、短辺方向Yに平行である。短辺方向Yは押圧方向Zに垂直であるため、本実施形態の移動方向Tは、押圧方向Zと交差している。
第2実施形態の溶着装置40を用いた電極ユニット10の製造方法では、第1実施形態と同様の工程S1~S7が行われる。なお、第1実施形態の電極ユニット10の製造方法では移動方向Tが長辺方向Xであったのに対し、第2実施形態では、移動方向Tが短辺方向Yとなっている。
シート材60の劣化は、シート材60において、樹脂押圧領域R1のうちの特に端縁E1と接触する領域で進行しやすい。言い換えれば、シート材60の劣化は、シート押圧領域R2のうち、押圧方向Zからの平面視において端縁E1と重なる領域で進行しやすい。端縁E1は、長辺方向Xに延びている。そのため、シート材60のなかで劣化が進行しやすい領域は、長辺方向Xに沿って分布しやすい。
(2-1)長辺方向Xは、押圧面51bの長辺が延びる方向である。また、移動方向Tは、長辺方向Xと交差する。
かかる構成において、端縁E1が延びる方向を長辺方向Xとすると、移動方向Tは長辺方向Xと交差する。
実施形態は以下のように変更して実施できる。実施形態及び以下の変形例は、技術的に矛盾しない範囲で互いに組み合わせて実施できる。
・第1実施形態及び第2実施形態において、移動機構70は、巻出部71及び巻取部75を備えていればよく、例えば巻出調節部72、第1支持部73a、第2支持部73b、及び巻取調節部74を備えていなくてもよい。この場合、支持部73a,73bは、押圧部51を用いて実現されてもよい。
・第1実施形態及び第2実施形態において、押圧面51bの形状は長方形に限られず、押圧面51bで樹脂部20,30を押圧可能であれば任意である。押圧面51bは、押圧方向Zからの平面視において、押圧面51bが樹脂部20,30の全体を含むように構成されていてもよい。この場合、押圧部51は、樹脂部20,30の全体を一度に押圧してもよい。なお、支持部73a,73bは、押圧方向Zからの平面視において、シート材60が樹脂部20,30の全体を含むように、シート材60を支持すればよい。
・第1実施形態及び第2実施形態において、樹脂部20,30は長方形の枠体のものに限らず、例えば電極板11の形状に合わせて任意の形状のものを採用できる。
・第1実施形態及び第2実施形態において、電極板11は、第1主面14及び第2主面15の両面に第1活物質層16及び第2活物質層17が配置されている、いわゆるバイポーラ電極でなくてもよい。電極板11は、例えば第1主面14及び第2主面15のいずれか一方にのみ活物質層16,17が設けられている、いわゆるモノポーラ電極であってもよい。
・第1実施形態及び第2実施形態において、溶着装置40は、2つの押圧アセンブリ50a,50bの一方のみが加熱部54を備えるものであってもよい。このような溶着装置40は、例えば樹脂部20,30のうちのいずれか一方のみを電極板11に溶着する場合に用いることができる。
