Description
図1は、本発明の第1実施形態に係る樹脂溶着方法の工程図と各工程における樹脂材の状態を示すものである。第1実施形態の樹脂溶着方法は、第2の樹脂材2の表面(境界面となる側の表面)21に対し吸収部22を形成する吸収部形成工程PA1と、吸収部22が形成された第2の樹脂材2に対し第1の樹脂材1を重ね合わせる重ね合わせ工程PA2と、重ね合わさせた第1及び第2の両樹脂材1,2を互いに溶着させる溶着工程PA3とを備えている。
溶着工程PA3では、レーザ装置41から連続レーザ光Rcを出射させて、第1の樹脂材1の上から上記第2の樹脂材の表面21の吸収部22に入射させる。すなわち、図2(b)にも示すように、連続レーザ光Rcを第1の樹脂材1の上から照射させると、その連続レーザ光Rcは第1の樹脂材1を透過して当接境界面を構成する表面21の吸収部22(図2(a)参照)に入射される。この連続レーザ光Rcの照射を受けて吸収部22が発熱し、この発熱により吸収部22近傍の第2の樹脂材2が溶融し、さらに吸収部22の発熱及び上記の溶融熱を受けて吸収部22近傍の第1の樹脂材1も溶融し始める。そして連続レーザ光Rcの通過後の放熱冷却により当接境界面を挟んだ両樹脂材1,2の溶融部分が互いに結合した状態で硬化し、両樹脂材1,2を互いに連結する溶着部23が形成されることになる。これにより、両樹脂材1,2のレーザ溶着が完了する。
図3は、本発明の第2実施形態に係る樹脂溶着方法の工程図と各工程における樹脂材の状態を示すものである。第2実施形態の樹脂溶着方法は、まず第1及び第2の両樹脂材1,2を互いに重ね合わせる重ね合わせ工程PB1を行い、次に、この重ね合わせた状態で当接境界面を構成する第2の樹脂材2の表面21に対し吸収部22を形成する吸収部形成工程PB2を行い、続いてその第1及び第2の両樹脂材1,2を互いに溶着させる溶着工程PB3を行うものである。なお、以後の説明では、第1実施形態の構成要素と同じものには第1実施形態と同一符号を付してその詳細な説明を省略する。
図4及び図5は、第1又は第2実施形態の樹脂溶着方法を適用して、浴室電気機器であるリモコン5の外装ケース51を構成する2つの部材である本体6と蓋7とを互いにレーザ溶着し、これにより、外装ケース51を水密構造にするようにした第3実施形態を示すものである。
