Abstract
【解決手段】ブリーダケース1におけるケース本体3と前蓋5との接合方法は、前蓋5の筒状部5bの内側にケース本体3を嵌め合わせる嵌合工程と、前蓋5とケース本体3とにレーザ光Lを照射し、前蓋5とケース本体3とをレーザ溶着させる溶着工程と、を備える。溶着工程では、嵌合工程で嵌め合わされた前蓋5とケース本体3とを回転軸線A方向に互いに押し付けながら、前蓋5とケース本体3とを、レーザ光Lの照射中に回転軸線A周りに複数回転させる。
【選択図】図3
Description
図1〜図3に示すように、本発明に係る樹脂部材の接合方法が適用されるブリーダケース1は、光電子増倍管を駆動するための回路基板を収納するものである。このブリーダケース1は、直径約17mmの円柱のカップ状をなす樹脂製のケース本体(第2の樹脂部材)3と、このケース本体3の開口側に取り付けられる樹脂製の前蓋(第1の樹脂部材)5と、ケース本体3の底側に取り付けられる樹脂製の後蓋7とを有している。前蓋5は、円盤状の基部5aと、この基部5aの周縁部に立設された円筒部(筒状部)5bとを有している。後蓋7も同様に、円盤状の基部7aと、基部7aの周囲に立設された円筒部7bとを有している。
図5に示すように、ブリーダケース21は、ケース本体23の嵌合部23cと前蓋25の嵌合部25cとが同じ高さに形成されている点で、上記ブリーダケース1と相違している。従って、嵌合工程において、嵌合部23cと嵌合部25cとが嵌合したときに、先端面23dと端面25dとが密着し、ブリーダケース1の第1の間隙s1に相当する間隙は形成されない。
図6に示すように、ブリーダケース31では、ケース本体33の嵌合部33cの外側面33eがテーパ面とされており、前蓋35の嵌合部35cの内側面35eも、その外側面33eに嵌合するテーパ面とされている。また、嵌合部33cの高さは、嵌合部35cの高さよりもわずかに低く形成されているので、先端面33dと端面35dとの間には、間隙s31が形成される。
図7に示すように、ブリーダケース41では、ケース本体43の嵌合部43cの外側面43eがテーパ面とされており、前蓋45の嵌合部45cの内側面45eも、その外側面43eに嵌合するテーパ面とされている。更に、嵌合部43cと嵌合部45cとが嵌合したときには、嵌合部43cの先端面43dが嵌合部45cの端面45dに突き当てられることで、このケース本体43と前蓋45とが位置決めされる。従って、先端面43dと端面45dとが密着し、ブリーダケース1の第1の間隙s1に相当する間隙は形成されない。
図8に示すように、ブリーダケース51において、前蓋55における嵌合部55cの先端には、内側面55eから内側に突出した爪部55gが形成されている。ケース本体53における嵌合部53cの外側面53eには、上記爪部55gに嵌合する溝53gが形成されている。また、嵌合部53cの高さは、嵌合部55cの高さよりもわずかに低く形成されているので、先端面53dと端面55dとの間には、間隙s51が形成される。
図9に示すように、ブリーダケース61では、ケース本体63の先端に嵌合部63cが形成されており、嵌合工程では、この嵌合部63cが、前蓋65における筒状部65bの先端部65cの内側に嵌め込まれることで、前蓋65とケース本体63とが連結される。
図10に示すように、ブリーダケース71は、円柱形状のブリーダケース1とは異なり、四角柱形状をなしている。このブリーダケース71は、嵌合部73cを有し略四角形の開口をもつカップ状のケース本体73と、嵌合部73cに嵌合する四角形の筒状部75bを有する前蓋75とを備えている。
図11に示すように、小型CCDカメラ80は、円柱形状をなし、レンズ86とCCD87とを収納する樹脂ケース81を備えている。樹脂ケース81は、円筒部85bを有するカップ状のケース本体(第1の樹脂部材)85と、キャップ83(第2の樹脂部材)とを備えている。このCCDカメラ80のレンズ86は、キャップ83の中央に形成された開口83hの縁部に、前方のレンズ面86aを当接させることで位置決めされ樹脂ケース81内に固定される。
図12に示すように、小型CCDカメラ90の樹脂ケース91は、キャップ(第1の樹脂部材)95と、ケース本体(第2の樹脂部材)93とを備えている。そして、ケース本体93の開口側の先端には、キャップ95の筒状部95bの内側に嵌め込まれる嵌合部93cが形成されている。このような構成にすれば、上記樹脂ケース81とは逆に、キャップ95の材料としてレーザ光Lを透過させる樹脂材料を用い、ケース本体93の材料としてレーザ光Lを吸収する樹脂材料を用いることができる。
図13に示す樹脂チューブ(第1の樹脂部材)105は、医療用等に用いられるものである。この樹脂チューブ105同士を連結するジョイント(第2の樹脂部材)103には、ジョイント本体103aから前後に突出した円筒状の突起部103c,103cが形成されている。この前後の突起部103c,103cがそれぞれ断面円形の樹脂チューブ105,105の内側に嵌め込まれることにより、樹脂チューブ105同士が連結される。このような樹脂チューブ105及びジョイント103の材料としては、PP(ポリプロピレン)やナイロンを用いることができが、例えば、双方ともPPを用いる、或いは、双方ともナイロンを用いるといったように、接合される樹脂チューブ105とジョイント103とを同種の材料とするのが接合強度の点で好ましい。ここで、樹脂チューブ105を形成する樹脂材料は、レーザ光Lを透過させるように調整されており、ジョイント103を形成する樹脂材料は、レーザ光Lを吸収するように調整されている。
