Abstract
Description
特開2005−246913号公報(特許文献2)には、樹脂同士を所定の間隔にあけた2本の溶着線上を2つのレーザ光をそれぞれ走査することによって予備溶着を行い、次いでその中間を溶着することで本溶着することが記載されている。
特開2006−73296号公報(特許文献3)には、ハウジングとレンズとを、それぞれ全周にわたってレーザ溶着される第1の溶着部と、第1の溶着部の外周側に全周にわたってレーザ溶着される第2の溶着部を備えられている構造やレーザ溶着方法が記載されている。
特開2010−162587号公報(特許文献4)には、電子機器や流量計において、レーザを含む熱溶着法を用いて、他の部材を固定する際に、回路基板等への熱の影響を抑制するために、断熱部が、流路保持体に設けられていることが記載されている。
上記特許文献1に開示されている技術では、接合する部分にレーザ走査を2回以上行うため、生産性に大きな問題がある。また、2回照射するため、溶着幅が増大し、バリが発生しやすいことも新たに発覚した。特許文献2に開示されている技術では、2つのレーザ光をそれぞれ走査するため、特許文献1と同様に生産性に大きな課題がある。その上、2つのレーザ光を照射するユニット自体が高く、装置コストも非常に高くなる。特許文献3に開示されている技術についても、上記特許文献1と同様に生産性に課題が残る。特許文献4に開示されている技術では、断熱部が、流路保持体に設けられていることが記載されているが、レーザ溶着を使用する場合、熱溶融領域はレーザ照射範囲近傍のみであり、電子部品に影響することはなく、問題にならない。特許文献5に開示されている技術では、予備溶着を行った後にその近傍に本溶着を実施するが、加圧時に予備溶着部を形成する樹脂同士の隙間が小さい場合などは、予備溶着部を形成した方が品質や信頼性が低下するという問題がある。これは、特許文献1の別形態、特許文献2、特許文献3についても同様のことが言える。
そこで、本発明の目的は、流量センサの生産性向上、高品質化・高信頼化、低コスト化を実現するカバーとハウジングのレーザ溶着構造や方法を提供することにある。
図17,18に本発明の一実施形態における流量センサのカバー(外形を破線で示す。)を外した内部の正面図、背面図を示す。
前記した回路パッケージ60は、図17,18に示す通り、流量センサ50のハウジング200内に設けられた回路室40に設置されており、図示されていないカバー(外形を破線で示す。)をハウジング200にレーザ溶着することによって、回路室の外気からの気密性が保たれる。本発明の主な特徴は、このレーザ溶着方法に係わる。
また、レーザ照射する際には、レーザ光源もしくはステージを移動させて、溶着させても良いし、ガルバノミラーを用いて高速にレーザ照射しても良い。
気泡(空孔)が残存すると、長期的な使用時に局所的に微小な剥離が起き、その微小な剥離の連結により、リークの発生原因となることは判っている。これに対して、多少の気泡が発生しても、強度自体の大幅な低下は起こさない特徴を持っていることが判った。
その際、金型上では、例えばH1とH3は0μm、H2は50μmと設計しておくことが望ましいが、実際のハウジング200では、ひけや反りを鑑みた形状に応じて、隙間H2>H3>H1となるようにすれば良い。ただし、その場合のH3及びH1は、最も隙間が大きい部分での値である。
これに対して、封止部を有する第1の溶着部301を形成する際に、図9に示すように、カバー100のレーザ溶着面と反対側に凹部を設け、カバー100の厚みを薄くしておくことが有効となる。本構造の場合、第1の溶着部301を形成する場合に、レーザ光が透過する部分を透明な加圧材2で加圧でき、加圧材2の劣化がない方法とすることが可能となる。その上、生産性向上の点でも有効な手段である。なお、第2の溶着部302に相当する部分にも、カバー100のレーザ溶着面と反対側に凹部を設けておいても良い。
