Abstract
Description
この搬送装置であれば、搬送装置が成形対象物を樹脂注入部側に向かう第1方向に移動させる第1移動機構と、当該第1方向とは異なる第2方向に移動させる第2移動機構を有するので、成形型に成形対象物を位置決めするための位置決めピンを設けなくても、また、成形対象物に成形型に対して位置決めするための位置決め孔を設けなくても、成形型に対して成形対象物を位置決めできる。これによって、成形型のコストダウンや製作期間の短縮等が可能となる。そして、搬送装置により位置決めされた成形対象物を樹脂封止することができるので、樹脂バリの発生を低減して、品質の良い樹脂成形品を製造することができる。
この構成であれば、第1移動機構の駆動部と第2移動機構の駆動部とを共通にすることができるので、構成を簡単化できるだけでなく、コストダウンを可能にすることができる。
この構成であれば、第1駆動部による第1方向の移動をカム部により第2方向の移動に変換できるので、その構成を簡単化することができる。
この構成であれば、第1接触部の移動量のバラツキや成形対象物の寸法のバラツキを吸収しつつ、成形対象物を第1方向において位置決めできるようになる。
この構成であれば、第2接触部の移動量のバラツキや成形対象物の寸法のバラツキを吸収しつつ、成形対象物を第2方向において位置決めできるようになる。
この構成において、位置決め途中における成形対象物の反りを抑えるためには、前記昇降移動機構を用いて、前記第1移動機構及び前記第2移動機構により位置決めされる前記成形対象物に対して前記押さえ部材を接近させることが望ましい。
この構成であれば、第1接触部と押さえ部材とを第1方向に移動させる駆動部を共通化することができるので、構成を簡単にすることができる。
この構成において、前記昇降移動機構は、前記樹脂を前記樹脂注入部に供給する際に、前記押さえ部材を前記成形対象物に接触しない位置に移動させることが望ましい。
この樹脂成形装置であれば、搬送装置により位置決めされた成形対象物を樹脂封止することができるので、樹脂バリの発生を低減して、品質の良い樹脂成形品を製造することができる。
この樹脂成形品の製造方法であれば、成形型に成形対象物を位置決めするための位置決めピンを設けなくても、また、成形対象物に成形型に対して位置決めするための位置決め孔を設けなくても、成形型に対して成形対象物を位置決めできるようになる。これによって、成形型のコストダウンや製作期間の短縮等が可能となる。そして、搬送装置により位置決めされた成形対象物を樹脂封止することができるので、樹脂バリの発生を低減して、品質の良い樹脂成形品を製造することができる。
以下に、本発明に係る樹脂成形装置の一実施形態について、図面を参照して説明する。なお、以下に示すいずれの図についても、わかりやすくするために、適宜省略し又は誇張して模式的に描かれている。同一の構成要素については、同一の符号を付して説明を適宜省略する。
本実施形態の樹脂成形装置100は、電子部品Wxが実装された成形対象物W1を樹脂材料Jを用いたトランスファー成形によって樹脂成形するものである。

次に、ローダ13の搬送動作及び位置決め動作について図7、図9〜図14を参照して説明する。
本実施形態の樹脂成形装置100によれば、搬送装置13が成形対象物W1をカルブロック141側に向かう第1方向に移動させる第1移動機構21と、当該第1方向とは異なる第2方向に移動させる第2移動機構22を有するので、下型15に成形対象物W1を位置決めするための位置決めピンを設けなくても、また、成形対象物W1に下型15に対して位置決めするための位置決め孔を設けることなく、下型15に対して成形対象物W1を位置決めできるようになる。
