Description
以下、樹脂製の筐体10と蓋体20とをレーザ溶着する例を、図面を用いて説明する。図1に示すように筐体10は、開口を有するキャビティ11を備えるとともに、筐体の底部に外部からキャビティ11まで通じた通気孔12が設けられている。そして、筐体10は、キャビティ11内にセンサや電子回路等の電子部品が格納されており、治具110を用いて載置台100の上に固定され、筐体10の開口部が蓋体20で蓋をされ、組立体を構成している。
本実施形態では、第1の実施の形態の変形例について説明する。本実施の形態における組立体(筐体10および蓋体20)の材料、並びに筐体と蓋体の溶着方法は、発明の第1の実施の形態と同様であるが、組立体は、以下のように構成される。すなわち、図2に示すように、筐体10は、蓋体20と当接する部位に開口に合わせて蓋体20に蓋をされた際に外部からキャビティ11まで通じる換気孔を形成する通気孔14が設けられている。なお、この換気孔(通気孔14)は、レーザ溶着等によって筐体10と蓋体20と溶着することによって塞がれ、筐体10と蓋体20は隙間なく溶着される。言い換えると、本実施の形態にかかる筐体と蓋体の溶着方法は、筐体10と蓋体20を溶着することで換気孔(通気孔14)を塞ぐことを含む。
第1の実施の形態、及び第2の実施の形態は、樹脂製の蓋体20を同じく樹脂製の筐体10にクランプ機構40で抑えてレーザ溶着する筐体と蓋体の溶着方法、及び筐体と蓋体の組立体についての例を示す図であるが、本発明はこれに限定されるものではない。すなわち、本発明は、溶着時にフュームが発生する筐体と蓋体の溶着方法、及び筐体と蓋体の組立体に好適に適用できる。本発明の他の実施の形態は、例えば金属製の筐体と蓋体とを筐体と蓋体の溶着方法、及び筐体と蓋体の組立体に適用されてもよい。また、筐体と蓋体は異種材料、例えば一方が金属製であり他方が樹脂製であってもよい。また、筐体は、異種材料を結合して構成されてもよい。例えば、蓋体と溶着される部位は樹脂製であり、その他は金属製であってもよい。同様に、蓋体も、異種材料を結合して構成されてもよい。また、本本実施の形態は、レーザ溶着とは異なる溶着技術、例えば筐体と蓋体とを溶着する際にフュームが発生するおそれがある熱溶着などの筐体と蓋体の溶着方法、及び筐体と蓋体の組立体に適用されてもよい。
