Description

【0001】
【発明の属する技術分野】
本発明は、チップ部品等の四角柱形状の電子部品を長さ向きに整列して供給する電子部品供給装置に関する。
【0002】
【従来の技術】
従来、この種の電子部品供給装置を開示するものとして特開平6−232596号公報がある。同公報に開示された装置は、貯蔵室内にバルク状態で収納されたチップ部品を部品搬送管を通じてベルト上に排出し、排出されたチップ部品をベルトによって前方に搬送する機能を有する。
【0003】
【発明が解決しようとする課題】
前記装置は、基本的には円柱形状のチップ部品を供給対象とするものであるため、近年主流となっている四角柱形状の電子部品(チップ部品を含む)の供給には不向きである。即ち、四角柱形状のチップ部品を供給する場合には、長さ方向の両端面を除く4側面の向きを揃える必要があるが、前記装置ではこのような姿勢制御を行うことができない。
【0004】
本発明は前記事情に鑑みて創作されたもので、四角柱形状の電子部品の供給に適した電子部品供給装置を提供することにある。
【0005】
【課題を解決するための手段】
前記目的を達成するため、本発明の電子部品供給装置は、長さ>幅=高さの寸法関係を有する四角柱形状の電子部品を方向無規制状態で収容し得る部品貯蔵室と、電子部品の幅寸法または高さ寸法よりも僅かに大きな間隙寸法と部品貯蔵室に向く上部開口と傾斜底面とを有し部品貯蔵室内の電子部品を1方向規制状態で取り込み得る扁平間隙が中央に形成されると共に該扁平間隙の両内壁の上部それぞれに内側に向かって下向きに傾く案内面が形成され、部品貯蔵室の下側に上下移動可能に配置されたスライダと、スライダに所定の上下運動を付与する駆動機構と、スライダが上下移動する過程で該スライダの扁平間隙内に1方向規制状態で取り込まれ傾斜底面の傾きに従って移動する電子部品を2方向規制状態で取り込み得るように扁平間隙に隣接して形成された部品通路とを備える、
ことを特徴とする電子部品供給装置。
【0006】
この電子部品供給装置によれば、スライダに上下運動を付与することにより、部品貯蔵室内に方向無規制状態で収容されている電子部品を扁平間隙内に1方向規制状態で取り込み、そして、この電子部品を部品通路内に2方向規制状態で取り込むことができる。
【0007】
本発明の前記目的とそれ以外の目的と、構成特徴と、作用効果は、以下の説明と添付図面によって明らかとなる。
【0008】
【発明の実施の形態】
[第1実施形態]
図1〜図6は本発明の第1実施形態を示すもので、以下の説明では図1における左を前、右を後、手前側を左、奥側を右として表記する。
【0009】
図1は装置の左面図、図2は図1のA1−A1線断面図、図3は図1のA2−A2線断面図、図4は図2のA3−A3線断面図、図5及び図6は装置の動作説明図である。
【0010】
第1実施形態として示した装置は、メインボディ1と、リッドプレート2と、取込パイプ3と、スライダ4と、スライダ駆動用のソレノイド5とを備える。
【0011】
メインボディ1は、上面を開口した直方体形状の空洞1aを有しており、この空洞1aの底面中央には、取込パイプ3の外形とほぼ一致した横断面形を有する取込パイプ用の取付孔1bが形成されている。また、取付孔1bの下側には、横断面正方形の部品通路1cが形成されている。この部品通路1cの横断面形は正方形であり、後述する電子部品Pの端面形状と相似形で僅かに大きい。ちなみに図示例では、縦部分と2つの傾斜部分と横部分とを連続させたものを部品通路1cとして示してある。さらに、メインボディ1の右側面には、ソレノイド5のアーム5aが上下移動可能に挿入される縦長の長穴1dが形成されている。
【0012】
取込パイプ3は所定長の金属パイプ等から成り、横断面正方形の内孔を有しその外形も正方形である。取込パイプ3の内孔の横断面形は電子部品Pの端面形状と相似形で僅かに大きく、前記部品通路1cの横断面形とほぼ一致している。取込パイプ3内に電子部品Pが取り込まれるときに、電子部品Pが取込パイプ3の上端で引っかからないようにするため、取込パイプ3の内孔上端の4辺には面取りや丸みが設けられている。この取込パイプ3はその下端部をメインボディ1の取付孔1bに差し込まれて固定されている。
【0013】
スライダ4は、メインボディ1の空洞1aの左右寸法よりも僅かに小さな左右寸法と空洞1aの前後寸法よりも僅かに小さな前後寸法を有しており、前後方向に延びる扁平な間隙4aを左右中央に有している。この扁平間隙4aは上部を開口しており、その左右寸法は電子部品Pの幅寸法または高さ寸法よりも僅かに大きく、且つ、電子部品Pの長さ寸法よりも小さい。また、扁平間隙4aには左側面から見てV字状となる傾斜底面4a1が形成されている。さらに、傾斜底面4a1の最深部には、前記取込パイプ3の外形と相似形で僅かに大きな横断面形を有するパイプ挿通孔4bが形成されている。さらにまた、扁平間隙4aの左内壁と右内壁の上部それぞれには、内側に向かって下向きに傾く案内面4cが形成されている。このスライダ4は、メインボディ1の空洞1a内に上下移動可能に挿入配置されており、パイプ挿通孔4bには取込パイプ3が挿入されている。スライダ4が下降位置にある状態では、パイプ挿通孔4bの上端は取込パイプ3の上端とほぼ一致している。
【0014】
ソレノイド5はメインボディ1の右側面に取り付けられ、そのアーム5aは長穴1dを通じてスライダ4に連結されている。
【0015】
この第1実施形態の装置では、メインボディ1の空洞1a内にスライダ4を挿入配置した状態においてスライダ4の上方空間が部品貯蔵室となり、この部品貯蔵室の上面開口はリッドプレート2によって開閉自在に覆われている。尚、以下の説明では部品貯蔵室に空洞1aと同じ符号1aを引用する。
【0016】
ここで、前述の装置における部品供給動作を説明する。
【0017】
部品供給に際しては、リッドプレート2を開けて電子部品Pを部品貯蔵室1a内に収容する。電子部品Pは、例えばチップコンデンサやチップインダクタやチップ抵抗器やチップジャンパー等の周知のチップ部品で、長さ>幅=高さの寸法関係を有した四角柱形状である。勿論、同様の形状を有するチップ部品以外の電子部品を収容しても構わない。
【0018】
部品供給を行うときには、部品収容後に、ソレノイド5によって下降位置にあるスライダ4を上昇させ、そして上昇位置から下降位置に復帰させる動作を繰り返す(図5及び図6参照)。
【0019】
このスライダ4の上下移動により、部品貯蔵室1a内に方向無規制状態で収容されている電子部品Pが撹拌作用を受け、収容部品Pが案内面4cを通じて或いは直接にスライダ4の扁平間隙4a内に1方向規制状態で取り込まれる。ちなみに、「方向無規制状態」とは、電子部品Pが3次元的に自由に動ける状態を意味し、「1方向規制状態」とは、電子部品Pが1方向の動きを規制されていて、電子部品Pが2次元的(平面的)に動ける状態を意味する。
【0020】
スライダ4の扁平間隙4a内に1方向規制状態で取り込まれた電子部品Pは同状態のまま下方に自重移動し、傾斜底面4a1の傾きに従ってパイプ挿通孔4bの上端に向かって移動する。スライダ4が下降位置にあるときは電子部品Pは直接取込パイプ3内に2方向規制状態で取り込まれるが、スライダ4が下降位置よりも上にあるときには電子部品Pは一旦パイプ挿通孔4b内に2方向規制状態で取り込まれ、ここから取込パイプ3内に2方向規制状態で取り込まれる。ちなみに、「2方向規制状態」とは、電子部品Pが2方向の動きを規制されていて、電子部品Pが1次元的(直線的)に動ける状態を意味する。
【0021】
取込パイプ3内に2方向規制状態で取り込まれた電子部品Pは同状態のまま下方に自重移動して部品通路1c内に取り込まれる。部品通路1c内に2方向規制状態で取り込まれた電子部品Pは、部品通路1cの縦部分と2つの傾斜部分を下方に自重移動して横向き姿勢で横部分に取り込まれる。
【0022】
部品通路1c内に2方向規制状態で取り込まれた電子部品Pを前方に搬送するときには、図示省略の吸引源、例えば機械的に動作されるシリンダや電動式真空ポンプ等を利用して、部品通路1cの前端に負圧を作用させる。部品通路1c内の電子部品Pはこの負圧作用によって前方に引き込まれ、部品通路1c内を前方に移動して目的位置まで搬送される。図示を省略してあるが、目的位置に搬送された電子部品Pは、前記負圧を一時的に解除したタイミングで吸着ノズル等によって順次外部に取り出され基板等に実装される。
【0023】
このように第1実施形態の装置によれば、スライダ4に上下運動を付与することにより、部品貯蔵室1a内に方向無規制状態で収容されている電子部品Pをスライダ4の扁平間隙4a内に1方向規制状態で取り込み、そして、この電子部品Pをパイプ挿通孔4b及び取込パイプ3を通じて部品通路1c内に2方向規制状態で取り込むことができる。
【0024】
つまり、四角柱形状の電子部品Pを、長さ方向の両端面を除く4側面の向きを揃えた状態で的確に供給することが可能であり、近年における需要者の要求(四角柱形状の電子部品の適正供給)に追従できる利点がある。また、装置構成がシンプルであるので装置を安価に構成でき、実用的効果も高い。
【0025】
[第2実施形態]
図7〜図13は本発明の第2実施形態を示すもので、以下の説明では図7における左を前、右を後、手前側を左、奥側を右として表記する。
【0026】
図7は装置の左側面図、図8は図7のB1−B1線断面図、図9は図7のB2−B2線断面図、図10は図8のB3−B3線断面図、図11はカバープレートとスライダの斜視図、図12及び図13は装置の動作説明図である。
【0027】
第2実施形態として示した装置は、メインボディ11と、カバープレート12と、リッドプレート13と、スライダ14と、スライダ駆動用のソレノイド15とを備える。
【0028】
メインボディ11は、左側面及び上面を開口した部品貯蔵室用の第1空洞11aを有し、その下部左側に左側面を開口したスライダ用の第2空洞11bを有しており、第1空洞11aには左側に左側に向かって下向きに傾く傾斜底面11a1が形成されている。また、メインボディ1の前側下部には、カバープレート12の張出部12bとの協同によって部品通路の一部を構成する延長部11cが形成されている。さらに、メインボディ11の右側面には、ソレノイド15のアーム15aが上下移動可能に挿入される縦長の長穴11dが形成されている。
【0029】
カバープレート12は、メインボディ11の左側面開口を閉塞する役目を果たし、その前側下部には、前記延長部11cと上下寸法を一致する延長部12aが形成されている。図11(A)から分かるように、カバープレート12の右側面下部の前側には、延長部12aにまで及ぶように、所定の厚みを有する張出部12bが形成されている。この張出部12bの厚みは、後述する電子部品Pの幅寸法または高さ寸法よりも僅かに大きく、且つ、電子部品Pの長さ寸法よりも小さい。また、張出部12bの上端には後側に向かって下向きに傾く傾斜面12b1が形成されている。また、張出部12bには、部品通路用の溝12b2が傾斜面12b1の最も低い箇所から延長部12aに及んで形成されている。この溝12b2の横断面形は正方形で、電子部品Pの端面形状と相似形で僅かに大きい。ちなみに図示例では、縦部分と2つの傾斜部分と横部分とを連続させたものを部品通路用の溝12b2として示してあり、縦部分の後壁はスライダ14の張出部14の前面を利用する関係から存在しない。
【0030】
スライダ14は、メインボディ11の第2空洞11bの左右寸法よりも小さな左右寸法と第2空洞11bの前後寸法よりも僅かに小さな前後寸法を有しており、左側に向かって下向きに傾く案内面14aを上部に有している。図示例ではこの案内面14aの傾斜角度を第1凹部11aの傾斜底面11a1の傾斜角度と一致させたものを示してあるが、案内面14aの傾斜角度は第1凹部11aの傾斜底面11a1よりも大きく(急に)したほうが好ましい。図11(B)から分かるように、スライダ14の左側面下部の後側には、カバープレート12の張出部12bと同一の厚みを有する張出部14bが形成されている。また、張出部14bの上端には後側に向かって下向きに傾く傾斜面14b1が形成されている。
【0031】
ソレノイド15はメインボディ11の右側面に取り付けられ、そのアーム15aは長穴11dを通じてスライダ14に連結されている。
【0032】
この第2実施形態の装置では、メインボディ11の第2空洞11b内にスライダ14を挿入配置し、メインボディ11左側面開口を閉塞した状態において、スライダ14及び傾斜底面11a1の上方空間が部品貯蔵室となり、この部品貯蔵室の上面開口はリッドプレート13によって開閉自在に覆われてる。尚、以下の説明では部品貯蔵室に第1空洞11aと同じ符号11aを引用する。
【0033】
また、同状態では、カバープレート12の張出部12bの右側面がスライダ14の張出部14bの存しない左側面に接していて、スライダ14の張出部14bの左側面がカバープレート12の張出部12の存しない右側面に接しており、カバープレート12の張出部12bの後面はスライダ14の張出部14bの前面と接している。
【0034】
さらに、同状態では、カバープレート12の張出部12bに形成されている部品通路用の溝12b2の右側面開口がスライダ14の張出部14bの存しない左側面と延長部11cの内面によって閉塞されて、これにより部品通路が構成されている。尚、以下の説明では部品通路に溝12b2と同じ符号12b2を引用する。
【0035】
さらにまた、同状態では、スライダ14の張出部14bの存しない左側面とカバープレート12の張出部12の存しない右側面との間に、電子部品Pの幅寸法または高さ寸法よりも僅かに大きく、且つ、電子部品Pの長さ寸法よりも小さな上部開口の扁平間隙(符号なし)が形成される。
【0036】
ここで、前述の装置における部品供給動作を説明する。
【0037】
部品供給に際しては、リッドプレート13を開けて電子部品Pを部品貯蔵室11a内に収容する。電子部品Pは、例えばチップコンデンサやチップインダクタやチップ抵抗器やチップジャンパー等の周知のチップ部品で、長さ>幅=高さの寸法関係を有した四角柱形状である。勿論、同様の形状を有するチップ部品以外の電子部品を収容しても構わない。
【0038】
部品供給を行うときには、部品収容後に、ソレノイド15によって下降位置にあるスライダ14を上昇させ、そして上昇位置から下降位置に復帰させる動作を繰り返す(図12及び図13参照)。
【0039】
このスライダ14の上下移動により、部品貯蔵室11a内に方向無規制状態で収容されている電子部品Pが撹拌作用を受け、収容部品Pが傾斜底面11a1及び案内面14aを通じて或いは直接にスライダ14とカバープレート12との間の扁平間隙内に1方向規制状態で取り込まれる。ちなみに、「方向無規制状態」とは、電子部品Pが3次元的に自由に動ける状態を意味し、「1方向規制状態」とは、電子部品Pが1方向の動きを規制されていて、電子部品Pが2次元的(平面的)に動ける状態を意味する。
【0040】
スライダ14とカバープレート12との間の扁平間隙内に1方向規制状態で取り込まれた電子部品Pは同状態のまま下方に自重移動し、傾斜面12b1及び傾斜面14b1の傾きに従って部品通路12b2の上端に向かって移動し、そして、部品通路12b2内に2方向規制状態で取り込まれる。ちなみに、「2方向規制状態」とは、電子部品Pが2方向の動きを規制されていて、電子部品Pが1次元的(直線的)に動ける状態を意味する。
【0041】
部品通路12b2内に2方向規制状態で取り込まれた電子部品Pは、部品通路12b2の縦部分と2つの傾斜部分を下方に自重移動して横向き姿勢で横部分に取り込まれる。
【0042】
部品通路12b2内に2方向規制状態で取り込まれた電子部品Pを前方に搬送するときには、図示省略の吸引源、例えば機械的に動作されるシリンダや電動式真空ポンプ等を利用して、部品通路12b2の前端に負圧を作用させる。部品通路12b2内の電子部品Pはこの負圧作用によって前方に引き込まれ、部品通路12b2内を前方に移動して目的位置まで搬送される。図示を省略してあるが、目的位置に搬送された電子部品Pは、前記負圧を一時的に解除したタイミングで吸着ノズル等によって順次外部に取り出され基板等に実装される。
【0043】
このように第2実施形態の装置によれば、スライダ14に上下運動を付与することにより、部品貯蔵室11a内に方向無規制状態で収容されている電子部品Pをスライダ14とカバープレート12との間の扁平間隙内に1方向規制状態で取り込み、そして、この電子部品Pを部品通路12b2内に2方向規制状態で取り込むことができる。
【0044】
つまり、四角柱形状の電子部品Pを、長さ方向の両端面を除く4側面の向きを揃えた状態で的確に供給することが可能であり、近年における需要者の要求(四角柱形状の電子部品の適正供給)に追従できる利点がある。また、装置構成がシンプルであるので装置を安価に構成でき、実用的効果も高い。
【0045】
[第3実施形態]
図14〜図19は本発明の第3実施形態を示すもので、以下の説明では図14における左を前、右を後、手前側を左、奥側を右として表記する。
【0046】
図14は装置の左側面図、図15は図14のC1−C1線断面図、図16は図15のC2−C2線断面図、図17はスライダの前面図と後面図、図18及び図19は装置の動作説明図である。
【0047】
第3実施形態として示した装置は、メインボディ21と、リッドプレート22と、スライダ23と、スライダ駆動用のソレノイド24とを備える。
【0048】
メインボディ21は、上面を開口した横断面長方形の空洞21aを有しており、この空洞21aには左側面から見てV字状となる傾斜底面21a1が形成されている。また、空洞21aの下側には、横断面長方形のスライダ挿通孔21bが形成されている。さらに、スライダ挿通孔21bの下部前側には、横断面正方形の部品通路21cが形成されている。この部品通路21cの横断面形は正方形であり、後述する電子部品Pの端面形状と相似形で僅かに大きい。ちなみに図示例では、傾斜部分と横部分とを連続させたものを部品通路21cとして示してある。さらに、メインボディ21の右側面には、ソレノイド24のアーム24aが上下移動可能に挿入される縦長の長穴(符号なし)が形成されている。
【0049】
スライダ23は、メインボディ21のスライダ挿通孔21bの左右寸法よりも僅かに小さな左右寸法とスライダ挿通孔21bの前後寸法よりも僅かに小さな前後寸法を有している。図17(A),(B)に示すように、このスライダ23は、前側に向かって下向きに傾く傾斜上面23aが形成されており、前後方向に延びる扁平な間隙23bを左右中央に有している。この扁平間隙23bは上部を開口しており、その左右寸法は電子部品Pの幅寸法または高さ寸法よりも僅かに大きく、且つ、電子部品Pの長さ寸法よりも小さい。また、扁平間隙23bには傾斜上面23aと同方向の傾きを有する傾斜底面23b1が形成されている。さらに、扁平間隙23bの左内壁と右内壁の上部それぞれには、内側に向かって下向きに傾く案内面23cが形成されている。このスライダ23は、メインボディ21のスライダ挿通孔21b内に上下移動可能に挿入配置されている。スライダ23が下降位置にある状態では、傾斜底面23b1の前端は部品通路21cの入口下辺とほぼ一致しており、傾斜上面23aの上端はスライダ挿通孔21bの上端よりも低いところにある。
【0050】
ソレノイド24はメインボディ21の右側面に取り付けられ、そのアーム24aは長穴を通じてスライダ23に連結されている。
【0051】
この第3実施形態の装置では、メインボディ21の空洞21aが部品貯蔵室となり、この部品貯蔵室の上面開口はリッドプレート22によって開閉自在に覆われている。尚、以下の説明では部品貯蔵室に空洞21aと同じ符号21aを引用する。
【0052】
部品供給に際しては、リッドプレート22を開けて電子部品Pを部品貯蔵室21a内に収容する。電子部品Pは、例えばチップコンデンサやチップインダクタやチップ抵抗器やチップジャンパー等の周知のチップ部品で、長さ>幅=高さの寸法関係を有した四角柱形状である。勿論、同様の形状を有するチップ部品以外の電子部品を収容しても構わない。
【0053】
部品供給を行うときには、部品収容後に、ソレノイド24によって下降位置にあるスライダ23を上昇させ、そして上昇位置から下降位置に復帰させる動作を繰り返す(図18及び図19参照)。
【0054】
このスライダ23の上下移動により、部品貯蔵室21a内に方向無規制状態で収容されている電子部品Pが撹拌作用を受け、収容部品Pが案内面23cを通じて或いは直接にスライダ23の扁平間隙23b内に1方向規制状態で取り込まれる。ちなみに、「方向無規制状態」とは、電子部品Pが3次元的に自由に動ける状態を意味し、「1方向規制状態」とは、電子部品Pが1方向の動きを規制されていて、電子部品Pが2次元的(平面的)に動ける状態を意味する。
【0055】
スライダ23の扁平間隙23b内に1方向規制状態で取り込まれた電子部品Pは同状態のまま下方に自重移動し、傾斜底面23b1の傾きに従って前方に滑動する。傾斜底面23b1の傾きに従って滑動する電子部品Pは、スライダ23が下降したときに部品通路21c内に2方向規制状態で取り込まれる。ちなみに、「2方向規制状態」とは、電子部品Pが2方向の動きを規制されていて、電子部品Pが1次元的(直線的)に動ける状態を意味する。
【0056】
部品通路21c内に2方向規制状態で取り込まれた電子部品Pは、部品通路21cの傾斜部分を下方に自重移動して横向き姿勢で横部分に取り込まれる。
【0057】
部品通路21c内に2方向規制状態で取り込まれた電子部品Pを前方に搬送するときには、図示省略の吸引源、例えば機械的に動作されるシリンダや電動式真空ポンプ等を利用して、部品通路21cの前端に負圧を作用させる。部品通路21c内の電子部品Pはこの負圧作用によって前方に引き込まれ、部品通路21c内を前方に移動して目的位置まで搬送される。図示を省略してあるが、目的位置に搬送された電子部品Pは、前記負圧を一時的に解除したタイミングで吸着ノズル等によって順次外部に取り出され基板等に実装される。
【0058】
このように第3実施形態の装置によれば、スライダ23に上下運動を付与することにより、部品貯蔵室21a内に方向無規制状態で収容されている電子部品Pをスライダ23の扁平間隙23b内に1方向規制状態で取り込み、そして、この電子部品Pを部品通路21c内に2方向規制状態で取り込むことができる。
【0059】
つまり、四角柱形状の電子部品Pを、長さ方向の両端面を除く4側面の向きを揃えた状態で的確に供給することが可能であり、近年における需要者の要求(四角柱形状の電子部品の適正供給)に追従できる利点がある。また、装置構成がシンプルであるので装置を安価に構成でき、実用的効果も高い。
【0060】
図20と図21は前記スライダ23の変形例をそれぞれ示してある。
【0061】
図20に示したスライダ25は、前記スライダ23と同様の、前側に向かって下向きに傾く傾斜上面25aと、前後方向に延びる扁平な間隙25bと、傾斜底面25b1と、案内面25cを有する他、前面下部の左右中央に、扁平間隙25bと同じ左右寸法を有し、且つ、電子部品Pの幅寸法または高さ寸法よりも僅かに大きな前後寸法を有する補助通路用の溝25dを扁平間隙25bの前側下部と連続するように有している。溝25dはスライダ25をスライダ挿通孔21b内に挿入配置した状態で前面開口を塞がれて補助通路(25d)となる。また、スライダ挿通孔21bの下部前側には、溝25d内の下部に入り込む案内突起21dが設けられている。
【0062】
図20(B)に示すように、扁平間隙25b内に1方向規制状態で取り込まれた電子部品Pは同状態のまま下方に自重移動し、傾斜底面25b1の傾きに従って前方に滑動して補助通路25d内に2方向規制状態で取り込まれる。補助通路25d内に2方向規制状態で取り込まれた電子部品Pは、案内突起21dによって移動方向を制御されつつ、部品通路21c内に2方向規制状態で取り込まれる。つまり、スライダ25の上下方向の位置に拘わらず、補助通路25d内に取り込まれた電子部品Pを部品通路21c内に送り込むことが可能となる。

DETAILED DESCRIPTION OF THE INVENTION
[First Embodiment]
1 to 6 show a first embodiment of the present invention. In the following description, the left in FIG. 1 is described as front, the right is rear, the front side is left, and the back side is right.
[0009]
1 is a left side view of the apparatus, FIG. 2 is a cross-sectional view taken along line A1-A1 of FIG. 1, FIG. 3 is a cross-sectional view taken along line A2-A2 of FIG. FIG. 6 is a diagram for explaining the operation of the apparatus.
[0010]
The apparatus shown as the first embodiment includes a main body 1, a lid plate 2, an intake pipe 3, a slider 4, and a solenoid 5 for driving the slider.
[0011]
The main body 1 has a rectangular parallelepiped cavity 1a having an open top surface. At the center of the bottom surface of the cavity 1a, the main body 1 is mounted for an intake pipe having a cross-sectional shape that substantially matches the outer shape of the intake pipe 3. A hole 1b is formed. Further, a component passage 1c having a square cross section is formed below the attachment hole 1b. The cross-sectional shape of the component passage 1c is a square, which is slightly larger than the end surface shape of the electronic component P described later. Incidentally, in the illustrated example, the part passage 1c is formed by connecting a vertical part, two inclined parts, and a horizontal part. Further, on the right side surface of the main body 1, a vertically long slot 1d into which the arm 5a of the solenoid 5 is inserted so as to be vertically movable is formed.
[0012]
The intake pipe 3 is made of a metal pipe or the like having a predetermined length, has an inner hole with a square cross section, and its outer shape is also square. The cross-sectional shape of the inner hole of the intake pipe 3 is similar to the end face shape of the electronic component P and slightly larger, and substantially coincides with the cross-sectional shape of the component passage 1c. In order to prevent the electronic component P from being caught at the upper end of the intake pipe 3 when the electronic component P is taken into the intake pipe 3, chamfering and rounding are provided on the four sides of the upper end of the inner hole of the intake pipe 3. Is provided. The lower end of the intake pipe 3 is fixed by being inserted into the mounting hole 1 b of the main body 1.
[0013]
The slider 4 has a lateral dimension slightly smaller than the lateral dimension of the cavity 1a of the main body 1 and a longitudinal dimension slightly smaller than the longitudinal dimension of the cavity 1a. Have. The flat gap 4a is open at the top, and its left and right dimensions are slightly larger than the width or height of the electronic component P and smaller than the length of the electronic component P. The flat gap 4a is formed with an inclined bottom surface 4a1 that is V-shaped when viewed from the left side. Further, a pipe insertion hole 4b having a slightly larger cross-sectional shape similar to the outer shape of the intake pipe 3 is formed in the deepest portion of the inclined bottom surface 4a1. Furthermore, a guide surface 4c is formed on each of the upper left and right inner walls of the flat gap 4a. The slider 4 is inserted and arranged in the cavity 1a of the main body 1 so as to be movable up and down, and the intake pipe 3 is inserted into the pipe insertion hole 4b. In the state where the slider 4 is in the lowered position, the upper end of the pipe insertion hole 4 b substantially coincides with the upper end of the intake pipe 3.
[0014]
The solenoid 5 is attached to the right side surface of the main body 1, and its arm 5a is connected to the slider 4 through a long hole 1d.
[0015]
In the apparatus of the first embodiment, the space above the slider 4 becomes a component storage chamber in a state where the slider 4 is inserted into the cavity 1 a of the main body 1, and the upper surface opening of the component storage chamber can be opened and closed by the lid plate 2. Covered with In the following description, the same reference numeral 1a as the cavity 1a is used for the parts storage chamber.
[0016]
Here, the component supply operation in the above-described apparatus will be described.
[0017]
When supplying the components, the lid plate 2 is opened and the electronic component P is accommodated in the component storage chamber 1a. The electronic component P is a known chip component such as a chip capacitor, a chip inductor, a chip resistor, or a chip jumper, and has a quadrangular prism shape having a dimensional relationship of length> width = height. Of course, electronic components other than chip components having the same shape may be accommodated.
[0018]
When supplying the parts, after the parts are accommodated, the operation of raising the slider 4 in the lowered position by the solenoid 5 and returning from the raised position to the lowered position is repeated (see FIGS. 5 and 6).
[0019]
Due to the vertical movement of the slider 4, the electronic component P accommodated in the component storage chamber 1 a in an unregulated direction is subjected to a stirring action, and the accommodated component P passes through the guide surface 4 c or directly in the flat gap 4 a of the slider 4. In a one-way restricted state. Incidentally, the “direction unregulated state” means a state in which the electronic component P can freely move three-dimensionally, and the “one-direction restricted state” means that the electronic component P is restricted from moving in one direction, This means that the electronic component P can move two-dimensionally (planar).
[0020]
The electronic component P taken in the flat gap 4a of the slider 4 in the one-way restricted state moves by its own weight while keeping the same state, and moves toward the upper end of the pipe insertion hole 4b according to the inclination of the inclined bottom surface 4a1. When the slider 4 is in the lowered position, the electronic component P is directly taken into the take-in pipe 3 in a two-way restricted state, but when the slider 4 is above the lowered position, the electronic component P is once in the pipe insertion hole 4b. Are taken in the two-way restricted state, and are taken into the intake pipe 3 from here in the two-way restricted state. Incidentally, the “two-way restricted state” means a state in which the electronic component P is restricted from moving in two directions and the electronic component P can move one-dimensionally (linearly).
[0021]
The electronic component P taken in the take-in pipe 3 in the two-way restricted state moves under its own weight while being in the same state, and is taken into the component passage 1c. The electronic component P taken in the component passage 1c in the two-direction restricted state is taken into the horizontal portion in a lateral posture by moving its own weight along the vertical portion and the two inclined portions of the component passage 1c.
[0022]
When the electronic component P taken in the two-way restricted state in the component passage 1c is transported forward, a suction source (not shown) such as a mechanically operated cylinder or an electric vacuum pump is used to A negative pressure is applied to the front end of 1c. The electronic component P in the component passage 1c is pulled forward by this negative pressure action, moves forward in the component passage 1c, and is transported to the target position. Although not shown, the electronic component P transported to the target position is sequentially taken out to the outside by a suction nozzle or the like at the timing when the negative pressure is temporarily released and mounted on the substrate or the like.
[0023]
As described above, according to the apparatus of the first embodiment, the electronic component P accommodated in the component storage chamber 1a in the direction unrestricted state is provided in the flat gap 4a of the slider 4 by giving the slider 4 a vertical motion. The electronic component P can be taken into the component passage 1c through the pipe insertion hole 4b and the intake pipe 3 in a two-way restricted state.
[0024]
In other words, the quadrangular prism-shaped electronic component P can be accurately supplied in a state in which the directions of the four side surfaces except the both end surfaces in the length direction are aligned. There is an advantage that it can follow the proper supply of parts). Further, since the apparatus configuration is simple, the apparatus can be configured at a low cost, and the practical effect is high.
[0025]
[Second Embodiment]
7 to 13 show a second embodiment of the present invention. In the following description, the left in FIG. 7 is represented as front, the right is rear, the near side is left, and the far side is right.
[0026]
7 is a left side view of the apparatus, FIG. 8 is a cross-sectional view taken along line B1-B1 of FIG. 7, FIG. 9 is a cross-sectional view taken along line B2-B2 of FIG. Is a perspective view of a cover plate and a slider, and FIG. 12 and FIG.
[0027]
The apparatus shown as the second embodiment includes a main body 11, a cover plate 12, a lid plate 13, a slider 14, and a solenoid 15 for driving the slider.
[0028]
The main body 11 includes a first cavity 11a for a component storage chamber having an opening on the left side and an upper surface, and a second cavity 11b for a slider having an opening on the left side on the lower left side thereof. An inclined bottom surface 11a1 is formed in the left side 11a. In addition, an extension portion 11 c that forms a part of the component passage is formed at the front lower portion of the main body 1 in cooperation with the overhang portion 12 b of the cover plate 12. Further, on the right side surface of the main body 11, a vertically long slot 11d into which the arm 15a of the solenoid 15 is inserted so as to be vertically movable is formed.
[0029]
The cover plate 12 serves to close the left side opening of the main body 11, and an extension portion 12a having the same vertical dimension as that of the extension portion 11c is formed at the front lower portion thereof. As can be seen from FIG. 11A, an overhanging portion 12b having a predetermined thickness is formed on the front side of the lower right side surface of the cover plate 12 so as to reach the extension portion 12a. The thickness of the overhanging portion 12b is slightly larger than the width or height of the electronic component P, which will be described later, and smaller than the length of the electronic component P. Further, an inclined surface 12b1 that is inclined downward toward the rear side is formed at the upper end of the overhang portion 12b. Further, a groove 12b2 for component passage is formed in the overhanging portion 12b from the lowest portion of the inclined surface 12b1 to the extension portion 12a. The cross-sectional shape of the groove 12b2 is a square, which is similar to the end face shape of the electronic component P and slightly larger. Incidentally, in the illustrated example, a continuous portion of a vertical portion, two inclined portions, and a horizontal portion is shown as a groove 12b2 for a part passage, and the rear wall of the vertical portion uses the front surface of the overhanging portion 14 of the slider 14. Does not exist from the relationship.
[0030]
The slider 14 has a lateral dimension smaller than the lateral dimension of the second cavity 11b of the main body 11 and a longitudinal dimension slightly smaller than the longitudinal dimension of the second cavity 11b, and is a guide surface inclined downward toward the left side. 14a at the top. In the illustrated example, the inclination angle of the guide surface 14a is shown to coincide with the inclination angle of the inclined bottom surface 11a1 of the first recess 11a. However, the inclination angle of the guide surface 14a is larger than that of the inclined bottom surface 11a1 of the first recess 11a. Larger (sudden) is preferable. As can be seen from FIG. 11B, an overhanging portion 14 b having the same thickness as the overhanging portion 12 b of the cover plate 12 is formed on the rear side of the lower portion of the left side surface of the slider 14. Further, an inclined surface 14b1 that is inclined downward toward the rear side is formed at the upper end of the overhanging portion 14b.
[0031]
The solenoid 15 is attached to the right side surface of the main body 11, and its arm 15a is connected to the slider 14 through a long hole 11d.
[0032]
In the apparatus according to the second embodiment, when the slider 14 is inserted into the second cavity 11b of the main body 11 and the left side opening of the main body 11 is closed, the space above the slider 14 and the inclined bottom surface 11a1 is used as a component storage. The upper opening of the component storage chamber is covered with a lid plate 13 so as to be opened and closed. In the following description, the same reference numeral 11a as that of the first cavity 11a is used for the parts storage chamber.
[0033]
In the same state, the right side surface of the overhanging portion 12b of the cover plate 12 is in contact with the left side surface of the overhanging portion 14b of the slider 14 and the left side surface of the overhanging portion 14b of the slider 14 is in contact with the cover plate 12. The projecting portion 12 is in contact with the right side surface where the projecting portion 12 does not exist, and the rear surface of the projecting portion 12 b of the cover plate 12 is in contact with the front surface of the projecting portion 14 b of the slider 14.
[0034]
Further, in this state, the right side opening of the component passage groove 12b2 formed in the overhanging portion 12b of the cover plate 12 is blocked by the left side surface where the overhanging portion 14b of the slider 14 does not exist and the inner surface of the extension portion 11c. Thus, a component passage is configured. In the following description, the same reference numeral 12b2 as that of the groove 12b2 is used for the component passage.
[0035]
Furthermore, in the same state, the width dimension or height dimension of the electronic component P is between the left side surface where the projecting portion 14 b of the slider 14 does not exist and the right side surface where the projecting portion 12 of the cover plate 12 does not exist. A flat gap (unsigned) of the upper opening that is slightly larger and smaller than the length dimension of the electronic component P is formed.
[0036]
Here, the component supply operation in the above-described apparatus will be described.
[0037]
When supplying the components, the lid plate 13 is opened and the electronic component P is accommodated in the component storage chamber 11a. The electronic component P is a known chip component such as a chip capacitor, a chip inductor, a chip resistor, or a chip jumper, and has a quadrangular prism shape having a dimensional relationship of length> width = height. Of course, electronic components other than chip components having the same shape may be accommodated.
[0038]
When supplying parts, after the parts are housed, the operation of raising the slider 14 in the lowered position by the solenoid 15 and returning it from the raised position to the lowered position is repeated (see FIGS. 12 and 13).
[0039]
Due to the vertical movement of the slider 14, the electronic component P accommodated in the component storage chamber 11 a in an unregulated direction is subjected to a stirring action, and the accommodated component P is brought into contact with the slider 14 through the inclined bottom surface 11 a 1 and the guide surface 14 a or directly. It is taken into the flat gap between the cover plate 12 in a one-way restricted state. Incidentally, the “direction unregulated state” means a state in which the electronic component P can freely move three-dimensionally, and the “one-direction restricted state” means that the electronic component P is restricted from moving in one direction, This means that the electronic component P can move two-dimensionally (planar).
[0040]
The electronic component P taken in the one-way restricted state into the flat gap between the slider 14 and the cover plate 12 moves under its own weight in the same state and moves in the component passage 12b2 according to the inclination of the inclined surface 12b1 and the inclined surface 14b1. It moves toward the upper end and is taken into the component passage 12b2 in a two-way restricted state. Incidentally, the “two-way restricted state” means a state in which the electronic component P is restricted from moving in two directions and the electronic component P can move one-dimensionally (linearly).
[0041]
The electronic component P captured in the component passage 12b2 in the two-direction restricted state is taken into the lateral portion in a lateral orientation by moving its weight downward along the vertical portion and the two inclined portions of the component passage 12b2.
[0042]
When the electronic component P captured in the two-way restricted state in the component passage 12b2 is transported forward, a suction source (not shown), for example, a mechanically operated cylinder or an electric vacuum pump is used. A negative pressure is applied to the front end of 12b2. The electronic component P in the component passage 12b2 is pulled forward by this negative pressure action, moves forward in the component passage 12b2, and is conveyed to the target position. Although not shown, the electronic component P transported to the target position is sequentially taken out to the outside by a suction nozzle or the like at the timing when the negative pressure is temporarily released and mounted on the substrate or the like.
[0043]
As described above, according to the apparatus of the second embodiment, by giving the slider 14 up and down movement, the electronic component P accommodated in the component storage chamber 11a in the direction unrestricted state is transferred to the slider 14, the cover plate 12, and the like. The electronic component P can be taken into the component passage 12b2 in a two-way restricted state.
[0044]
In other words, the quadrangular prism-shaped electronic component P can be accurately supplied in a state in which the directions of the four side surfaces except the both end surfaces in the length direction are aligned. There is an advantage that it can follow the proper supply of parts). Further, since the apparatus configuration is simple, the apparatus can be configured at a low cost, and the practical effect is high.
[0045]
[Third Embodiment]
14 to 19 show a third embodiment of the present invention. In the following description, the left in FIG. 14 is represented as front, the right is rear, the near side is left, and the far side is right.
[0046]
14 is a left side view of the apparatus, FIG. 15 is a cross-sectional view taken along line C1-C1 of FIG. 14, FIG. 16 is a cross-sectional view taken along line C2-C2 of FIG. 19 is an explanatory diagram of the operation of the apparatus.
[0047]
The apparatus shown as the third embodiment includes a main body 21, a lid plate 22, a slider 23, and a slider driving solenoid 24.
[0048]
The main body 21 has a cavity 21a having a rectangular cross section with an open top surface, and an inclined bottom surface 21a1 having a V shape when viewed from the left side surface is formed in the cavity 21a. A slider insertion hole 21b having a rectangular cross section is formed below the cavity 21a. Furthermore, a part passage 21c having a square cross section is formed on the lower front side of the slider insertion hole 21b. The cross-sectional shape of the component passage 21c is square, and is slightly larger than the end surface shape of the electronic component P described later. Incidentally, in the illustrated example, a part passage 21c is shown in which an inclined portion and a lateral portion are continuous. Further, on the right side surface of the main body 21, a vertically long slot (not shown) into which the arm 24a of the solenoid 24 is inserted so as to be vertically movable is formed.
[0049]
The slider 23 has a lateral dimension slightly smaller than the lateral dimension of the slider insertion hole 21b of the main body 21 and a longitudinal dimension slightly smaller than the longitudinal dimension of the slider insertion hole 21b. As shown in FIGS. 17A and 17B, the slider 23 is formed with an inclined upper surface 23a inclined downward toward the front side, and has a flat gap 23b extending in the front-rear direction at the center of the left and right. Yes. The flat gap 23b is open at the top, and its left and right dimensions are slightly larger than the width dimension or height dimension of the electronic component P and smaller than the length dimension of the electronic component P. In addition, an inclined bottom surface 23b1 having an inclination in the same direction as the inclined upper surface 23a is formed in the flat gap 23b. Furthermore, a guide surface 23c is formed on each of the upper part of the left inner wall and the right inner wall of the flat gap 23b. The slider 23 is inserted and arranged in the slider insertion hole 21b of the main body 21 so as to be vertically movable. When the slider 23 is in the lowered position, the front end of the inclined bottom surface 23b1 substantially coincides with the lower entrance side of the component passage 21c, and the upper end of the inclined upper surface 23a is lower than the upper end of the slider insertion hole 21b.
[0050]
The solenoid 24 is attached to the right side surface of the main body 21, and its arm 24a is connected to the slider 23 through a long hole.
[0051]
In the apparatus of the third embodiment, the cavity 21a of the main body 21 serves as a component storage chamber, and the upper surface opening of the component storage chamber is covered with a lid plate 22 so as to be freely opened and closed. In the following description, the same reference numeral 21a as the cavity 21a is referred to in the parts storage chamber.
[0052]
When supplying the components, the lid plate 22 is opened and the electronic component P is accommodated in the component storage chamber 21a. The electronic component P is a known chip component such as a chip capacitor, a chip inductor, a chip resistor, or a chip jumper, and has a quadrangular prism shape having a dimensional relationship of length> width = height. Of course, electronic components other than chip components having the same shape may be accommodated.
[0053]
When supplying parts, after the parts are housed, the operation of raising the slider 23 in the lowered position by the solenoid 24 and returning it from the raised position to the lowered position is repeated (see FIGS. 18 and 19).
[0054]
Due to the vertical movement of the slider 23, the electronic component P accommodated in the component storage chamber 21a is subjected to a stirring action, and the accommodated component P passes through the guide surface 23c or directly in the flat gap 23b of the slider 23. In a one-way restricted state. Incidentally, the “direction unregulated state” means a state in which the electronic component P can freely move three-dimensionally, and the “one-direction restricted state” means that the electronic component P is restricted from moving in one direction, This means that the electronic component P can move two-dimensionally (planar).

The electronic component P taken in the flat gap 23b of the slider 23 in the unidirectional restriction state moves under its own weight while keeping the same state, and slides forward according to the inclination of the inclined bottom surface 23b1. The electronic component P that slides according to the inclination of the inclined bottom surface 23b1 is taken into the component passage 21c in a two-way restricted state when the slider 23 is lowered. Incidentally, the “two-way restricted state” means a state in which the electronic component P is restricted from moving in two directions and the electronic component P can move one-dimensionally (linearly).
[0056]
The electronic component P taken in the component passage 21c in a two-way restricted state is taken into the lateral portion in a lateral posture by moving its weight downward in the inclined portion of the component passage 21c.
[0057]
When the electronic component P taken in the two-way restricted state into the component passage 21c is transported forward, the component passage is utilized by using a suction source (not shown) such as a mechanically operated cylinder or an electric vacuum pump. A negative pressure is applied to the front end of 21c. The electronic component P in the component passage 21c is pulled forward by this negative pressure action, moves forward in the component passage 21c, and is conveyed to the target position. Although not shown, the electronic component P transported to the target position is sequentially taken out to the outside by a suction nozzle or the like at the timing when the negative pressure is temporarily released and mounted on the substrate or the like.

In addition, an inclined surface 26b1 that is V-shaped when viewed from the front surface is formed at the upper end of the overhanging portion 26b, and a groove 26b2 having a lateral dimension slightly larger than the width dimension or the height dimension of the electronic component P is formed in the center of Is formed. The groove 26b2 closes the front opening in a state where the slider 26 is inserted and arranged in the slider insertion hole 21b, and becomes an auxiliary passage (26b2). Further, in the state where the slider 26 is inserted into the slider insertion hole 21b, the width dimension or height of the electronic component P is between the portion where the protruding portion 26 on the front surface of the slider 26 does not exist and the inner surface of the slider insertion hole 21b. A flat gap (unsigned) that is slightly larger than the length and smaller than the length of the electronic component P is formed. Furthermore, a guide projection 21d that enters the lower portion of the groove 26b2 is provided on the lower front side of the slider insertion hole 21b.
[0064]
As shown in FIG. 21B, the housing component P is taken in a one-way restricted state through the guide surface 26a or directly into the flat gap between the slider 26 and the slider insertion hole, and the electronic component P is inclined to the inclined surface 26b1. Is taken into the auxiliary passage 26b2 in a two-way restricted state. The electronic component P taken into the auxiliary passage 26b2 in the two-way restricted state is taken into the component passage 21c in the two-way restricted state while the movement direction is controlled by the guide projection 21d. That is, regardless of the vertical position of the slider 26, the electronic component P taken into the auxiliary passage 26b2 can be sent into the component passage 21c.
