Abstract
Description
回路基板搬送保持装置4は、回路基板P(以下、基板Pと略称する)を水平な姿勢で搬送して保持するものであり、図1において、基板Pの搬送方向をx方向、基板Pの幅方向をy方向、基板Pの厚み方向をz方向とする。y方向は装着機の前後方向であり、z方向は上下方向である。これら、x方向、y方向、z方向は互いに直交する。部品供給装置6は、基板Pに装着される電子部品(以下、部品と略称する)sを供給するものであり、複数のテープフィーダ14等を含む。ヘッド移動装置8は、装着ヘッド16を保持してx、y、z方向へ移動させるものであり、装着ヘッド16は、部品sを吸着して保持する吸着ノズル18を有する。
突出部36bは、図6B,図6Cに示すように、溝部46に係合可能な大きさ、形状を成す。突出部36bは、下溝部46bに係合する下溝係合部57と、上溝部46aの一部に係合する上溝係合部58とを含む。上溝係合部58は、溝部46の一対の傾斜面48a、48bの一部に対向する一対の傾斜面58a、58bを有する。下溝係合部57は、それぞれ、下溝部46bの底面50、一対の壁面51a、51bに対向する下端面57d、一対の側面57a,57bを有する。本体部36aは、溝部46の一対の傾斜面48a、48bから離間している。
測定装置22は、常には、図9Aに示す初期状態にある。可動子36は後退端位置にあり、載置台32は前進端位置にある。部品sの電気的特性の測定指令が出されると、装着ヘッド16が移動させられる。吸着ノズル18によって部品sが保持され、移動させられ、溝部46に載置させられる。
