Description

【0001】
【発明の属する技術分野】
この発明は、例えば、多数のチップ状の電子部品が格子状に連接されたシート基板を複数のチップ状の電子部品が一列に連接された短冊状に分割して搬送し、収納するワーク搬送収納装置及びワーク搬送収納方法に関する。
【0002】
【従来の技術】
図4は、多数のチップ状の電子部品1を格子状に連接されたシート基板2であり、2aは耳の部分を示す。図5は、シート基板2を分割して複数のチップ状の電子部品1を一列に連接した短冊状の電子部品3(以下、単にワーク3という)を示す。
シート基板2を分割して電子部品1を一列に連接したワーク3は、従来、図6及び図7に示すワーク搬送収納装置によって搬送・収納している。図6は搬送収納部分の平面図で、図7は搬送収納部分の正面図である。
少なくとも一対のベルト駆動輪4(一方のみ図示)には搬送ベルト5が掛け渡され、ベルト駆動輪4は駆動機構(図示しない)によって間欠回転し、搬送ベルト5は矢印方向に1ピッチずつ間欠走行するようになっている。前記シート基板2から分割手段(図示しない)によって分割されたワーク3は1本ずつ分離されてその長手方向が搬送ベルト5の搬送方向と直角方向に載置され、搬送ベルト5の間欠走行に伴って搬送される。この場合、搬送ベルト5の間欠送り区間一つに対してワーク3が1本の割合で載置される。
搬送ベルト5の搬出側には移載機構6が設けられている。この移載機構6には水平方向にアーム7が設けられている。このアーム7の基端部下側には搬送ベルト5の搬送方向と直角方向の横搬送路8が設けられ、このアーム7の先端部は搬送ベルト5の水平下流端位置Cより上流側まで延長している。
アーム7にはワーク3を吸着するための吸着ヘッド9が設けられ、この吸着ヘッド9は吸着ヘッド駆動機構10によってアーム7の基端部と先端部との間を直線往復運動可能である。
横搬送路8の上面にはその長手方向に亘って搬送溝11が設けられ、搬送溝11の一端側にはアクチュエータ12のプッシャ13が設けられている。搬送溝11の他端側にはワーク3を次工程へ搬送するためのマガジン14への投入口15が設けられている。
【0003】
なお、マガジン14はベルト駆動輪4の支持機構あるいはアーム7の支持及び駆動機構の設置上、ベルト5の駆動輪4の直後から離して設けられている。
従って、搬送ベルト5によって搬送されたワーク3が水平下流端位置Cより上流側の吸着ヘッド9の待機位置に到達すると、真空吸引された吸着ヘッド9によってワーク3が吸着される。なお、ここで、吸着ヘッド9の待機位置が水平下流端位置Cより下流側にすると、ワーク3が搬送ベルト5の湾曲した折り返し部に位置して傾斜あるいは落下するため吸着不能となる。
吸着ヘッド9にワーク3が吸着されると、吸着ヘッド駆動機構10によって吸着ヘッド9がアーム7の先端部側から基端部側へ直線移動する。そして、ワーク3を吸着した吸着ヘッド9が横搬送路8の搬送溝11の上部に位置すると、吸着ヘッド9は吸着を解放し、吸着ヘッド9に吸着されていたワーク3が搬送溝11に移載される。
次に、アクチュエータ12が作動し、プッシャ13によって搬送溝11内のワーク3は押圧されて投入口15に位置すると、ワーク3はマガジン14に収納される。この間に、吸着ヘッド9は吸着ヘッド駆動機構10によってアーム7の先端部側へ移動し、待機位置に復帰するとともに、プッシャ13もアクチュエータ12によって後退する。この動作を繰り返して搬送ベルト5によって順次搬送されるワーク3をマガジン14に収納することができる。
【0004】
【発明が解決しようとする課題】
しかしながら、前述したワーク搬送収納装置は、吸着ヘッド9とプッシャ13の往復動作と、さらにこの往復動作に同期させた搬送ベルト5でそれぞれが間隔の開いたワーク3を間欠的に搬送させるため、各作業には例えば往復動作が終了しないと次の作業に移れない等のシーケンス要素もあって、速度に限界があり、一連の処理の高速化が困難である。また、マガジン14が一杯となったとき、マガジン14を交換するには、ワーク搬送収納装置を一時停止させる必要がある。
【0005】
この発明は、前記事情に着目してなされたもので、その目的とするところは、例えば、複数のチップ状電子部品を一列に連接した短冊状のワークを搬送して収納するまでの一連の処理速度の高速化が可能で、しかも装置を停止させることなくマガジンを交換できるワーク搬送収納装置及びワーク搬送収納方法を提供することにある。
【0006】

【0010】
【発明の実施の形態】
以下、この発明の実施の形態を図面に基づいて説明する。
【0011】
図1及び図2はワーク搬送収納装置の一つの実施形態を示し、図1は搬送収納部分の平面図で、図2は搬送収納部分の縦断正面図、図3は移載機構の拡大した正面図である。このワーク搬送収納装置は、例えば、図4に示す、多数のチップ状の電子部品1を格子状に連接されたシート基板2を図5に示すように、シート基板2を分割して複数のチップ状の電子部品1を一列に連接した短冊状電子部品3(以下、単にワーク3という)を搬送収納するものである。
【0012】
搬送路20は、搬送路20の両側に設けられた一次搬送ベルト21と、この一次搬送ベルト21の搬出側に設けられた二次搬送ベルト22とによって構成されている。搬送路20にはアイドラホイール23が設けられ、この両端部に一次搬送ベルト用転輪24が設けられている。
【0013】
一次搬送ベルト用転輪24の間には二次搬送ベルト用転輪25が設けられている。一次搬送ベルト用転輪24には一次搬送ベルト21が掛け渡されている。二次搬送ベルト用転輪25には二次搬送ベルト22が掛け渡されている。
【0014】
一次搬送ベルト用転輪24と二次搬送ベルト用転輪25とは同軸で、かつ各々が独立して回転自在に設けられている。すなわち、図示しないベルト駆動輪からアイドラホイール23及びその他のアイドラホイール23aを経由して二列の一次搬送ベルト21が平行に設けられ、ベルト駆動輪とアイドラホイール23間において概ね水平の一次搬送路が形成されている。
【0015】
アイドラホイール23の中央部の二次搬送ベルト用転輪25の両端側からベルト駆動輪26及び他のアイドラホイール23bを経由してベルト駆動輪26とアイドラホイール23間において概ね水平で、かつ一次搬送路と概ね面一に二次搬送路が形成されている。さらに、二次搬送路の搬送速度は一次搬送路の搬送速度に対して少なくとも1.5倍になるように設定されている。そして、一次搬送路から二次搬送路にワーク3が移載される際に、先頭のワーク3aと後続のワーク3とが分離搬送されるようになっている。
【0016】
二次搬送路のワーク移載位置P1には、分離搬送された先頭のワーク3aを位置決めするためのストッパ27が二次搬送路の外側にそれぞれ1個設けられ、さらにワーク移載位置P1の先頭のワーク3aの有無を検知する検知センサ28が設けられている。
【0017】
二次搬送路を構成する二次搬送ベルト22の搬出側における上側には駆動手段(図示しない)によって間欠回転する搬送テーブル30が設けられている。この搬送テーブル30は円板状で、その上面は搬送路20の水平面と平行に設けられている。この搬送テーブル30の上面には後述する複数の移載機構31が放射状に等配して設けられている。そして、搬送テーブル30の間欠回転に伴って複数の移載機構31のうち、一つが二次搬送路のワーク移載位置P1で先頭のワーク3aと対峙するようになっている。
【0018】
搬送テーブル30の隣側で、かつ下側には収納テーブル32がその周縁部の一部が搬送テーブル30とラップするように設けられている。この収納テーブル32は円板状で、駆動手段33によって一定角度毎に回転自在であり、収納テーブル32の上面は搬送テーブル30の上面と平行に設けられている。
【0019】
収納テーブル32の上面には複数のワーク3を収納する収納部としてのマガジン34が放射状に等配して設けられている。このマガジン34は、収納テーブル32の外側に設けられた外側マガジンガイド35と内側マガジンガイド36にそれぞれ対向して設けられた保持手段としてのガイド溝35a,36aに上下方向に抜き差し自在に立設されている。
【0020】
次に、前記移載機構31について説明すると、図3に示すように、搬送テーブル30には一対のリニアボールブッシュ37が上下方向に貫通して設けられている。リニアボールブッシュ37にはリニアシャフト38がスライド自在に貫通されている。一対のリニアシャフト38の上端部はコイルスプリング39を貫通して上部に設けられた受け部材40に連結されている。
【0021】
一対のリニアシャフト38の下端部は緩衝部材41を貫通して吸着ヘッド42の上面に連結されている。吸着ヘッド42の下面における左右両端部には吸着面43が突出して設けられている。さらに、両吸着面43は複数の真空吸引孔44が設けられ、この真空吸引孔44は真空連通孔45を介して真空発生源(図示しない)に連通している。
【0022】
前記受け部材40の長手方向の中間部には調整ポインタ46が調整可能に螺合されている。調整ポインタ46の直下の搬送テーブル30には下限ストッパ47が調整可能に螺合されている。そして、調整ポインタ46及び下限ストッパ47によってそれぞれ吸着面43のストローク及び吸着面高さが調整できるようになっている。
【0023】
また、ワーク移載位置P1及びワーク収納位置P2には移載機構31の調整ポインタ46を押圧して吸着ヘッド42を下方にスライドさせるためのプッシャ48aを有するアクチュエータ48が設けられている。そして、調整ポインタ46及び下限ポインタ47により、それぞれの吸着面43のストローク及び吸着面高さが調整されるようになっている。
【0024】
さらに、ワーク移載位置P1とワーク収納位置P2との間には搬送されるワーク3の良否を判定する白黒の明度差を検知するセンサ49が設けられている。センサ49は、チップ部品1の黒色系を検知して良品と判定するとともに、チップ部品1が含まれない所謂耳と呼ばれる部分2a(図4参照)のセラミックスの白色を検知して不良ワーク3bと判定するようになっている。不良と判定された不良ワーク3bはワーク収納位置P2より搬送テーブル30の回転前方に設けられた不良ワーク収納箱50に収納する不良ワーク収納手段を備えている。
【0025】
また、ワーク収納位置P2より収納テーブル32の回転後方には満載マガジン34を検知するためのセンサ51が設けられている。さらに、ワーク収納位置P2には、その上面が収納テーブル32の下面より下方を待避位置P3とするスライド支持板52が設けられている。このスライド支持板52は、図示しない駆動手段により上下方向にスライド移動自在に設けられ、収納テーブル32に設けられた貫通孔53を貫通してマガジン34内を上下にスライドできるようになっている。
【0026】
次に、前述のように構成されたワーク搬送収納装置の作用について説明する。
図5に示すように、シート基板2を分割して複数のチップ状の電子部品1を一列に連接した複数の短冊状のワーク3が連接されて搬送路20の一次搬送ベルト21によって図1及び図2の矢印方向に搬送される。一次搬送ベルト21の水平下流端Bであるアイドラホイール23まで搬送されると、一次搬送ベルト21とアイドラホイール23を共有する二次搬送ベルト22は、その水平上流端Baが一次搬送ベルト21の水平下流端Bと共通であるため、その水平上流端Baにおいて一次搬送ベルト21から二次搬送ベルト22に先頭のワーク3aが移載される。
【0027】
一次搬送ベルト21の搬送速度に対して二次搬送ベルト22の搬送速度は1.5倍以上に設定されているため、一次搬送ベルト21で搬送されてきた先頭のワーク3aが二次搬送ベルト22に移載されると、搬送速度の差で後続するワーク3と分離される。そして、二次搬送ベルト22によって搬送され、ワーク移載位置P1においてストッパ27に当接して位置決めされる。
【0028】
一次搬送ベルト21の先頭のワーク3aが二次搬送ベルト22により搬送されると、後続のワーク3が新たな先頭のワーク3aとなって二次搬送ベルト22に移載される。そして、前述のように後続のワーク3と分離され、この繰り返しによりワーク3が順次搬送される。
【0029】
ワーク移載位置P1において検知センサ28により二次搬送ベルト22の先頭のワーク3aが検知されると、アクチュエータ48が作動してプッシャ48aが突出する。そして、プッシャ48aによって移載機構31の調整ポインタ46を押し下げ、リニアシャフト38を介して吸着ヘッド42を押し下げる。
【0030】
吸着ヘッド42の吸着面43が先頭のワーク3aに接近すると同時に、吸着面43の真空吸引孔44から吸引される吸引力によって吸着面43にワーク3aが吸着される。このとき、吸着面43の下降位置は受け部材40の下面が下限ストッパ47に当接することにより規制される。
【0031】
ワーク3aが吸着面43に吸着保持されると、アクチュエータ48は解放され、プッシャ48aが没入して調整ポインタ46への押圧力が低減すると、コイルスプリング39によって受け部材40が押し戻される。受け部材40が押し戻されると、リニアシャフト38がリニアボールブッシュ37内をスライドしてリニアシャフト38の下端に連結された吸着ヘッド42を引き戻す。
【0032】
一方、このとき、収納テーブル32にセットされた複数のマガジン34のうち、一つが駆動手段33によって割出し駆動されてワーク収納位置P2に位置決めされて待機している。
【0033】
ワーク3aが未収納のマガジン34がワーク収納位置P2に位置決めされると、スライド支持板52が駆動手段によって駆動されて待避位置P3からスライド上昇し、割出しテーブル32の貫通孔53を貫通してマガジン34の底部からマガジン34内に進入して移載機構31からマガジン34にワーク3aを移載される位置(高さ)に上面が到達して停止する。
【0034】
移載機構31にワーク3aが吸着保持され、吸着ヘッド42がコイルスプリング39に付勢されて引き戻されると、搬送テーブル30が駆動手段によって間欠回転してワーク収納位置P2に搬送される過程で、センサ49により搬送されるワーク3aの良否が判定される。ここで、不良ワーク3bとは、例えば、白色セラミックス製のシート基板2のうち、黒色のチップ部品が含まれない通常の耳2aと呼ばれる白色の両端部分であって、色の濃淡検知、すなわち白黒の明度差を検知するセンサ49により耳2aが検知されると、ワーク収納位置P2を通過して不良ワーク収納箱50まで搬送されて不良ワーク収納箱50に収納される。また、センサ49が正常ワーク3aと判定した場合はワーク収納位置P2に搬送され、アクチュエータ48のプッシャ48aによって吸着ヘッド42が押し下げられ、マガジン34への移載位置(高さ)において真空吸引孔44が大気開放されてワーク3aがマガジン34に落下して移載収納される。
【0035】
ワーク3がマガジン34に収納される毎に、スライド支持板52がワーク3の厚さ分だけスライド下降し、収納されたワーク3の上面が常にワーク移載レベルに保たれる。
【0036】
アクチュエータ48が解放されて吸着ヘッド42が上昇位置に引き戻されると、再び搬送テーブル30が間欠回転して後続する移載機構31がワーク収納位置P2に位置決めされる。そして、前述したプロセスに従ってワーク3が順次マガジン34に収納され、マガジン34がワーク3で満杯になると、スライド支持板52が待避位置P3にスライド下降する。
【0037】
その後、収納テーブル32が割出し回転して満載マガジン34が割出し1ピッチ分搬送されると共に、次の空のマガジン34がワーク収納位置P2に搬送されて位置決めされて待機する。満載となってマガジン34は、収納テーブル32が1周する間に空マガジン34と交換され、ワーク収納位置P2には常に空のマガジン34が位置決めされる。しかし、満載マガジン34と空マガジン34とが交換されなかった場合は、ワーク収納位置P2の手前において、センサ51により満載マガジン34が検出されることにより、全ての前記プロセスが停止して待機する。
【0038】
従って、搬送路20から搬送されたワーク3は搬送テーブル30によって搬送される過程で、ワーク3の良否を判定し、良品のワーク3のみを収納テーブル32のマガジン34に収納することができる。しかも、マガジン34がワーク3で満杯となっても装置を停止することなく、空のマガジン34と交換でき、搬送路20からマガジン34に収納されるまでの一連の処理速度が高速化されるという効果がある。

[0020]
Next, the transfer mechanism 31 will be described. As shown in FIG. 3, the transfer table 30 is provided with a pair of linear ball bushes 37 vertically penetrating therethrough. A linear shaft 38 is slidably penetrated through the linear ball bush 37.

Further, both suction surfaces 43 are provided with a plurality of vacuum suction holes 44, and the vacuum suction holes 44 communicate with a vacuum generation source (not shown) through vacuum communication holes 45.
[0022]
An adjustment pointer 46 is threadably engaged with an intermediate portion of the receiving member 40 in the longitudinal direction. A lower limit stopper 47 is threadably engaged with the transport table 30 immediately below the adjustment pointer 46. The stroke of the suction surface 43 and the height of the suction surface can be adjusted by the adjustment pointer 46 and the lower limit stopper 47, respectively.
[0023]
An actuator 48 having a pusher 48a for pressing the adjustment pointer 46 of the transfer mechanism 31 to slide the suction head 42 downward is provided at the work transfer position P1 and the work storage position P2. Then, the stroke and the suction surface height of each suction surface 43 are adjusted by the adjustment pointer 46 and the lower limit pointer 47.
[0024]
Further, between the work transfer position P1 and the work storage position P2, there is provided a sensor 49 for detecting a difference in brightness between black and white for judging pass / fail of the work 3 to be conveyed. The sensor 49 detects the black color of the chip part 1 and determines that the chip part 1 is non-defective, and detects the white color of the ceramic in a so-called ear portion 2a (see FIG. 4) that does not include the chip part 1 and determines the defective work 3b. The judgment is made. The defective work 3b which is determined to be defective is provided with a defective work storage means for storing the defective work 3b in a defective work storage box 50 provided in the rotation front of the transfer table 30 from the work storage position P2.
[0025]
Further, a sensor 51 for detecting the full loaded magazine 34 is provided behind the work storage position P2 in the rotation of the storage table 32. Further, at the work storage position P2, a slide support plate 52 whose upper surface is lower than the lower surface of the storage table 32 is set as a retracted position P3. The slide support plate 52 is provided so as to be slidable in a vertical direction by a driving unit (not shown), and can slide up and down in the magazine 34 through a through hole 53 provided in the storage table 32.
[0026]
Next, the operation of the work transport / storage device configured as described above will be described.
As shown in FIG. 5, a plurality of strip-shaped works 3 in which the sheet substrate 2 is divided and a plurality of chip-shaped electronic components 1 are connected in a row are connected to each other, It is transported in the direction of the arrow in FIG. When transported to the idler wheel 23 which is the horizontal downstream end B of the primary transport belt 21, the secondary transport belt 22 sharing the idler wheel 23 with the primary transport belt 21 has its horizontal upstream end Ba horizontal to the primary transport belt 21. Since it is common to the downstream end B, the leading work 3a is transferred from the primary conveyance belt 21 to the secondary conveyance belt 22 at the horizontal upstream end Ba.
[0027]
Since the transport speed of the secondary transport belt 22 is set to be 1.5 times or more the transport speed of the primary transport belt 21, the first work 3 a transported by the primary transport belt 21 is removed from the secondary transport belt 22. Is separated from the succeeding work 3 by a difference in the transport speed. Then, the sheet is conveyed by the secondary conveying belt 22 and is positioned by contacting the stopper 27 at the work transfer position P1.
[0028]
When the first work 3a of the primary transfer belt 21 is transferred by the secondary transfer belt 22, the subsequent work 3 becomes a new first work 3a and is transferred to the second transfer belt 22. Then, the work 3 is separated from the subsequent work 3 as described above, and the work 3 is sequentially conveyed by this repetition.
[0029]
When the leading sensor 3a of the secondary transport belt 22 is detected by the detection sensor 28 at the workpiece transfer position P1, the actuator 48 operates to push the pusher 48a. Then, the adjustment pointer 46 of the transfer mechanism 31 is pushed down by the pusher 48a, and the suction head 42 is pushed down via the linear shaft 38.
[0030]
At the same time as the suction surface 43 of the suction head 42 approaches the leading work 3a, the work 3a is sucked to the suction surface 43 by the suction force sucked from the vacuum suction hole 44 of the suction surface 43. At this time, the lowering position of the suction surface 43 is regulated by the lower surface of the receiving member 40 abutting on the lower limit stopper 47.
[0031]
When the work 3a is sucked and held on the suction surface 43, the actuator 48 is released, and when the pusher 48a enters and the pressing force on the adjustment pointer 46 decreases, the receiving member 40 is pushed back by the coil spring 39. When the receiving member 40 is pushed back, the linear shaft 38 slides in the linear ball bush 37 and pulls back the suction head 42 connected to the lower end of the linear shaft 38.
[0032]
On the other hand, at this time, one of the plurality of magazines 34 set on the storage table 32 is indexed and driven by the driving means 33, is positioned at the work storage position P2, and stands by.
[0033]
When the magazine 34 in which the work 3a has not been stored is positioned at the work storage position P2, the slide support plate 52 is driven by the driving means and slides up from the retreat position P3, and passes through the through hole 53 of the indexing table 32. The upper surface reaches the position (height) at which the work 3a enters the magazine 34 from the bottom of the magazine 34 and is transferred from the transfer mechanism 31 to the magazine 34, and stops.
[0034]
When the work 3a is sucked and held by the transfer mechanism 31 and the suction head 42 is urged by the coil spring 39 and pulled back, the transfer table 30 is intermittently rotated by the driving means and is transferred to the work storage position P2. The quality of the work 3a conveyed by the sensor 49 is determined. Here, the defective work 3b is, for example, the both ends of white called a normal ear 2a which does not include a black chip part in the sheet substrate 2 made of white ceramics. When the ear 2a is detected by the sensor 49 that detects the difference in brightness of the workpiece, the ear 2a is conveyed to the defective work storage box 50 through the work storage position P2 and stored in the defective work storage box 50. If the sensor 49 determines that the workpiece 3a is normal, it is transported to the workpiece storage position P2, the suction head 42 is pushed down by the pusher 48a of the actuator 48, and the vacuum suction hole 44 is transferred to the magazine 34 at the transfer position (height). Is released to the atmosphere, and the work 3a falls to the magazine 34 and is transferred and stored.
[0035]
Each time the work 3 is stored in the magazine 34, the slide support plate 52 slides down by the thickness of the work 3, and the upper surface of the stored work 3 is always maintained at the work transfer level.
[0036]
When the actuator 48 is released and the suction head 42 is returned to the raised position, the transport table 30 rotates again intermittently, and the subsequent transfer mechanism 31 is positioned at the work storage position P2. Then, the works 3 are sequentially stored in the magazine 34 according to the above-described process, and when the magazine 34 is filled with the works 3, the slide support plate 52 slides down to the retreat position P3.
[0037]
Thereafter, the storage table 32 is indexed and rotated, the full magazine 34 is conveyed by one pitch, and the next empty magazine 34 is conveyed to the work storage position P2 and is positioned and stands by. When full, the magazine 34 is replaced with an empty magazine 34 while the storage table 32 makes one round, and the empty magazine 34 is always positioned at the work storage position P2. However, if the full magazine 34 and the empty magazine 34 are not exchanged, the full magazine 34 is detected by the sensor 51 just before the work storage position P2, and all the processes stop and wait.
[0038]
Therefore, the quality of the work 3 conveyed from the conveyance path 20 can be determined in the process of being conveyed by the conveyance table 30, and only the good work 3 can be stored in the magazine 34 of the storage table 32. Moreover, even if the magazine 34 is full of the work 3, the apparatus can be replaced with an empty magazine 34 without stopping the apparatus, and a series of processing speeds from the transfer path 20 to the storage in the magazine 34 are increased. effective.
Further, by simultaneously performing the suction holding and the transfer / storage of the work 3 independently and independently, there is no loss time required for the reciprocating operation, and the conveyance / storage can be performed with high efficiency.
[0039]
In the above-described embodiment, a case is described in which a plurality of chip-shaped electronic components are divided into sheet substrates connected in a grid pattern, and a plurality of chip-shaped electronic components are conveyed and housed in a strip. Although described, the present invention is not limited to the transport of electronic components, but can be applied to the transport and storage of all components. In addition, although the components are sucked and transported by the suction head, they may be gripped and transported by a gripping hand.
[0040]
