Abstract
【解決手段】本樹脂成形品は、第1樹脂材(プラグ材2)及び第2樹脂材(通路形成材3)を突き合わせてレーザ光の照射により接合してなる樹脂成形品(オイルフィルタブラケット1)であって、第1樹脂材及び第2樹脂材の突き合わせ面側にレーザ光の照射により形成される溶着部7と、第1樹脂材及び第2樹脂材の突き合わせ面側の溶着部の両側に設けられ、レーザ光の照射時に生じる発泡樹脂の流れを防止する流れ防止部8と、を備える。
【選択図】図2
Description
請求項2に記載の発明は、請求項1記載において、前記第1樹脂材及び前記第2樹脂材のうちの一方の樹脂材には、他方の樹脂材に向かって突出する凸部が設けられ、他方の樹脂材には該凸部が入り込む凹部が設けられ、前記流れ防止部は、前記凸部を形成する凸部側壁面、及び該凸部側壁面に当接し且つ前記凹部を形成する凹部側壁面により構成されていることを要旨とする。
請求項3に記載の発明は、請求項2記載において、前記凸部側壁面及び前記凹部側壁面のそれぞれは、前記第1樹脂材及び前記第2樹脂材の突き合わせ方向に対して傾斜していることを要旨とする。
上記問題を解決するために、請求項4に記載の発明は、請求項1乃至3のいずれか一項に記載の樹脂成形品の製造方法であって、前記第1樹脂材及び前記第2樹脂材を突き合わせる工程と、突き合わされた前記第1樹脂材及び前記第2樹脂材をレーザ光の照射により接合する工程と、を備え、前記突き合わせる工程では、前記第1樹脂材及び前記第2樹脂材の突き合わせ面側の溶着予定部の両側に前記流れ防止部が形成され、前記接合する工程では、前記第1樹脂材及び前記第2樹脂材の突き合わせ面側に前記溶着部が形成されるとともに、前記流れ防止部により前記レーザ光の照射時に生じる発泡樹脂の流れが防止されることを要旨とする。
また、前記第1樹脂材及び前記第2樹脂材のうちの一方の樹脂材に凸部が設けられ、他方の樹脂材に凹部が設けられ、前記流れ防止部が凸部側壁面及び凹部側壁面により構成されている場合は、これら凸部側壁面及び凹部側壁面の当接により発泡樹脂の流れが防止される。
さらに、前記凸部側壁面及び前記凹部側壁面のそれぞれが、前記第1樹脂材及び前記第2樹脂材の突き合わせ方向に対して傾斜している場合は、これら凸部側壁面及び凹部側壁面が更に強固に当接される。
本実施形態1.に係る樹脂成形品は、第1樹脂材(2)及び第2樹脂材(3)を突き合わせてレーザ光の照射により接合してなる樹脂成形品(1)であって、第1樹脂材及び第2樹脂材の突き合わせ面側にレーザ光の照射により形成される溶着部(7)と、第1樹脂材及び第2樹脂材の突き合わせ面側の溶着部の両側に設けられ、レーザ光の照射時に生じる発泡樹脂の流れを防止する流れ防止部(8)と、を備えることを特徴とする(例えば、図2等参照)。上記流れ防止部は、通常、レーザ光の照射部位から離間している。なお、上記「両側」とは、第1樹脂材及び第2樹脂材の突き合わせ方向に略直交する方向の両側を意図する。また、上記「流れ」とは、レーザ光の照射部位からその両側に向かう流れを意図する。
本実施形態2.に係る樹脂成形品の製造方法は、上記実施形態1.に係る樹脂成形品の製造方法であって、第1樹脂材(2)及び第2樹脂材(3)を突き合わせる工程と、突き合わされた第1樹脂材及び第2樹脂材をレーザ光(L)の照射により接合する工程と、を備え、突き合わせる工程では、第1樹脂材及び第2樹脂材の突き合わせ面側の溶着予定部の両側に上記流れ防止部(8)が形成され、接合する工程では、第1樹脂材及び第2樹脂材の突き合わせ面側に溶着部が形成されるとともに、流れ防止部によりレーザ光の照射時に生じる発泡樹脂(S)の流れが防止されることを特徴とする(例えば、図6等参照)。上記接合する工程では、通常、流れ防止部にはレーザ光が照射されない。
本実施例に係るオイルフィルタブラケット1は、図1に示すように、レーザ透過性樹脂(例えば、ナイロン等)からなるプラグ材2(本発明に係る「第1樹脂材」として例示する。)と、レーザ吸収性樹脂(例えば、ナイロン等)からなる通路形成材3(本発明に係る「第2樹脂材」として例示する。)と、を備えている。
次に、上記構成のオイルフィルタブラケット1の製造方法について説明する。図5に示すように、プラグ材2の雄ネジ部2aを通路形成材3の雌ネジ部3dに螺合して、プラグ材2を開口部3cを塞ぐように通路形成材3に装着する。すると、プラグ材2のフランジ部2bと通路形成材3の表面側とが所定の加圧力(例えば、約1MPa程度)で突き合わされる。また、図6(a)に示すように、各凸部10が各凹部11に嵌合して、各凸部10の内側壁面10aが各凹部11の内側壁面11aに当接することで流れ防止部8が形成される。なお、各凸部10の外側壁面10bと各凹部11の外側壁面11bとは隙間をもって対向している。
以上より、本実施例のオイルフィルタブラケット1によると、プラグ材2及び通路形成材3の突き合わせ面側の溶着部7の両側に設けられる流れ防止部8を備えるので、流れ防止部8によりレーザ光Lの照射時に生じる発泡樹脂Sがレーザ光の照射部位の両側へ流れることが防止される。その結果、プラグ材2及び通路形成材3を密封状態で且つ強固に接合することができる。
