Description
真空ホルダは、照明装置を製造する際のように、反射体としての中空体の開口部に照明板をレーザー光線で溶接するときに用いられ、当該中空体を真空室に対して真空保持する装置である。具体的には、真空室に環状のパッキン板を載置し、このパッキン板に中空体を載せ、開口部に照明板を継ぎ合わせ、真空室を負圧に維持する。負圧はパッキン板の環状孔を通して中空体の内部に通じ、照明板を開口部に吸引保持する。この状態でレーザー光線を継目に沿って照射することで、照明板が中空体の開口部に溶接される。負圧を暫く維持することで、溶接継目が密に形成されたか否かを検査することができる。しかしながら、真空室の真空漏れを防止するためにパッキン板やOリングのようなシール部材が必要であり、しかも、これらのシール部材は、使用回数が増えるとともに劣化が避けられず、頻繁な交換を強いられるという問題がある。

前記治具は、前記収納ケースを支持する支持台と、前記支持台に前記コネクタ部を挿入可能に設けられており前記コネクタ部の挿入状態で前記支持台上での前記収納ケースの位置決めをする孔部とを備えており、
前記孔部に接続されており、レーザー光溶着の際に前記コネクタ部を吸引して前記ハウジングを前記支持台上に吸引支持する吸引機構が設けられていること
を特徴とする収納ケースのレーザー光溶着装置。 - 前記収納部と前記コネクタ部とは通気孔を通じて連通構成とされており、前記レーザー光溶着の際に、前記吸引機構による負圧が前記通気孔を通じて前記収納部に及ぶことで前記カバーを前記ハウジングの前記開口部に吸引保持することを特徴とする請求項5に記載の収納ケースのレーザー光溶着装置。
- 前記吸引機構による吸引後に、負圧低下の有無を圧力センサで検出することにより、前記レーザー光溶着の実施後における前記レーザー光溶着部分の負圧漏れの検査を行うことを特徴とする請求項6に記載の収納ケースのレーザー光溶着装置。
- 前記孔部には、前記コネクタ部の先端部分に密着当接するとともに前記孔部に通じる吸引孔が形成されているラバー部材が設けられていることを特徴とする請求項5〜7のいずれか1項に記載の収納ケースのレーザー光溶着装置。
