Description

本発明は、長手方向に一定間隔で部品を収納したテープ部材を進行させて部品取り出し口に部品を供給するテープフィーダ及びこのテープフィーダを備えた部品実装装置に関するものである。   The present invention relates to a tape feeder that feeds a component to a component take-out port by advancing a tape member that accommodates the component at regular intervals in the longitudinal direction, and a component mounting apparatus including the tape feeder.

基板に部品(電子部品)を装着する部品実装装置は、基板の位置決めを行う基板位置決め部、部品の供給を行う部品供給部、部品供給部より供給された部品をピックアップして基板位置決め部により位置決めされた基板に装着する装着ヘッドを備えている。部品供給部としては、例えば、長手方向に一定間隔で部品を収納したテープ部材を進行させて部品取り出し口に部品を供給するテープフィーダが知られている。   A component mounting apparatus that mounts a component (electronic component) on a substrate includes a substrate positioning unit that positions the substrate, a component supply unit that supplies components, and picks up the components supplied from the component supply unit and positions them using the substrate positioning unit. A mounting head for mounting on the printed circuit board. As a component supply unit, for example, a tape feeder is known in which a tape member that stores components at regular intervals in the longitudinal direction is advanced to supply components to a component take-out port.

テープフィーダは、テープ部材の通路であるテープ通路を備えたフィーダ本体と、フィーダ本体に設けられて外周部に多数の突起を有したスプロケットを備えて成り、テープ部材はポケット状の各部品収納部に部品を収納させたベーステープと、ベーステープの表面に貼り付けられて部品収納部に収納された部品がベーステープから脱落することを防止するトップテープから成る。テープ部材の長手方向には一定間隔で送り孔が設けられており、リールから繰り出されたテープ部材はフィーダ本体のテープ通路上を延び、フィーダ本体の先端部において送り孔にスプロケットの突起が係合される。スプロケットの間欠的な回転によってテープ通路上をテープ部材が進行し、部品収納部が一定時間おきに部品取り出し位置に到達して部品が供給される。   The tape feeder comprises a feeder main body having a tape passage which is a passage of the tape member, and a sprocket provided on the feeder main body and having a plurality of protrusions on the outer peripheral portion, and the tape member is a pocket-shaped component storage portion. And a top tape that prevents a component that is affixed to the surface of the base tape and stored in the component storage unit from falling off the base tape. Feed holes are provided at regular intervals in the longitudinal direction of the tape member. The tape member fed from the reel extends on the tape passage of the feeder body, and the sprocket protrusion engages with the feed hole at the tip of the feeder body. Is done. The tape member advances on the tape path due to intermittent rotation of the sprocket, and the component storage unit reaches the component take-out position at regular intervals to supply the component.

トップテープは部品収納部が部品取り出し位置に到達する手前の位置においてベーステープから引き剥がされ、スプロケットの近傍位置においてテープ部材の上方を覆うカバー部材のトップテープ引き出し口からテープ部材の進行方向とは反対の方向に引き出され、一定のテンションが与えられた状態で巻き取られて回収される。スプロケットの各突起の位置はスプロケットの回転角度と関連づけて把握され、部品取り出し位置に対する部品収納部の位置が正確にコントロールされる。   The top tape is peeled off from the base tape at a position just before the parts storage part reaches the parts take-out position, and the tape member travel direction from the top tape outlet of the cover member covering the top of the tape member at a position near the sprocket. It is pulled out in the opposite direction, and is wound and collected in a state where a certain tension is applied. The position of each projection of the sprocket is grasped in association with the rotation angle of the sprocket, and the position of the component storage portion with respect to the component removal position is accurately controlled.

このようなテープフィーダでは、スプロケットの回転動作によるテープ部材の進行が進んでテープ部材が終端部に至ったときには、そのテープ部材の終端部に新たなリールのテープ部材の先頭部がテープ状の連結部材によってスプライシングされるが(例えば、特許文献1)、そのテープ部材の連結部の位置(連結部材の位置)は、部品のロット管理等のために検出される必要があり、従来のテープフィーダにはテープ部材の連結部(連結部材が取り付けられた部分)を検出するための連結部検出装置が備えられている。この連結部検出装置は、テープ通路上を進行するテープ部材の送り孔の移動経路上に検査光を射出し、その射出した検査光をテープ部材の送り孔が横切る状態が変化したことに基づいてテープ部材の連結部を検出するようになっている。具体的には、射出した検査光がスプロケットの回転動作に応じて進行するテープ部材の送り孔によって周期的に断続される状態が続いた後、スプロケットが回転動作を行っているにも拘らず検査光が断続される状態が一定時間検出されなかったことを検知したときには、そのとき連結部材が検査光を通過したものとしてテープ部材の連結部の位置を検出する。   In such a tape feeder, when the tape member advances due to the rotating operation of the sprocket and the tape member reaches the terminal portion, the leading portion of the tape member of the new reel is connected in a tape-like manner to the terminal portion of the tape member. Although splicing is performed by a member (for example, Patent Document 1), the position of the connecting portion of the tape member (the position of the connecting member) needs to be detected for part lot management, etc. Is provided with a connecting part detecting device for detecting a connecting part of the tape member (part to which the connecting member is attached). This connecting part detection device emits inspection light onto the moving path of the feed hole of the tape member that travels on the tape path, and based on the change in the state that the feed hole of the tape member crosses the emitted inspection light. The connection part of a tape member is detected. Specifically, after the inspection light that has been emitted continues to be periodically interrupted by the tape member feed hole that travels in response to the rotation of the sprocket, the inspection is performed even though the sprocket is rotating. When it is detected that the state where light is interrupted is not detected for a certain period of time, the position of the connecting portion of the tape member is detected as the connecting member has passed the inspection light at that time.

しかしながら、上記従来のテープフィーダでは、検査光の射出位置は設定された設計上の位置から幾分ずれてしまうことがあるうえ、フィーダ本体のテープ通路上を進行するテープ部材はテープ部材の横方向(テープ部材の進行方向と直交する方向)に移動し得ることから、テープ通路上をテープ部材が進行してもテープ部材の送り孔が検査光を横切らず、テープ部材の送り孔から外れた箇所において検査光が遮断された状態が継続した場合には、実際にはテープ部材の連結部でない箇所が連結部であると誤認(誤検出)されてしまい、これがもとで部品のロット管理等が正しく行われなくなる不具合が発生するおそれがあるという問題点があった。   However, in the conventional tape feeder, the inspection light emission position may slightly deviate from the set design position, and the tape member traveling on the tape path of the feeder body is in the lateral direction of the tape member. Since the tape member can move in the direction perpendicular to the direction of travel of the tape member, the tape member feed hole does not cross the inspection light even if the tape member travels on the tape path, and the location where the tape member feed hole is removed. In the case where the inspection light is interrupted in step 2, the part that is not the connecting part of the tape member is actually misidentified (erroneously detected) as the connecting part. There was a problem that there was a possibility that a malfunction that would not be performed correctly occurred.

図4において、カバー部材33の部品取り出し口33aの前方の位置には覗き窓33nが設けられている。この覗き窓33nは、カバー部材33がフィーダ本体31に対して閉じた状態において、スプロケット32の突起32bがテープ部材20の送り孔22と係合する位置の直上に設けられている。このため部品実装装置1のオペレータは、この覗き窓33nからスプロケット32の突起32bがテープ部材20の送り孔22に正常に係合しているかどうかを確認することができる。   In FIG. 4, a viewing window 33n is provided at a position in front of the component outlet 33a of the cover member 33. The viewing window 33n is provided immediately above the position where the protrusion 32b of the sprocket 32 engages with the feed hole 22 of the tape member 20 in a state where the cover member 33 is closed with respect to the feeder main body 31. For this reason, the operator of the component mounting apparatus 1 can confirm whether or not the projection 32b of the sprocket 32 is normally engaged with the feed hole 22 of the tape member 20 from the viewing window 33n.

スプロケット32が間欠的に回転すると、スプロケット32によって牽引されたテープ部材20がフィーダ本体31のテープ通路31a上を進行し、テープ部材20の部品収納部21が一定時間間隔でカバー部材33の部品取り出し口33aの下方位置に位置して部品取り出し口33aに部品4が供給される。トップテープ20bは各部品収納部21がカバー部材33の部品取り出し口33aに到達する以前にベーステープ20aから引き剥がされてカバー部材33の上面側に引き出され、トップテープ回収部34によって回収されるので、部品収納部21がカバー部材33の部品取り出し口33aに到達した時点において、部品4は部品収納部21から取り出せる状態となる。   When the sprocket 32 rotates intermittently, the tape member 20 pulled by the sprocket 32 advances on the tape passage 31a of the feeder body 31, and the component storage portion 21 of the tape member 20 takes out the component of the cover member 33 at regular time intervals. The component 4 is supplied to the component take-out port 33a located below the port 33a. The top tape 20 b is peeled off from the base tape 20 a before each component storage portion 21 reaches the component take-out port 33 a of the cover member 33, pulled out to the upper surface side of the cover member 33, and collected by the top tape collection portion 34. Therefore, when the component storage unit 21 reaches the component extraction port 33 a of the cover member 33, the component 4 can be extracted from the component storage unit 21.

図3及び図4において、トップテープ回収部34はテンション付与機構35、一対の回収ローラ36及び回収ボックス37を有して成り、テンション付与機構35のばね部材35aによってテンションを与えた状態のトップテープ20bを一対の回収ローラ36によって挟み込んで引っ張り、回収ボックス37内に収納して回収する。   3 and 4, the top tape recovery unit 34 includes a tension applying mechanism 35, a pair of recovery rollers 36 and a recovery box 37, and the top tape in a state where tension is applied by the spring member 35 a of the tension applying mechanism 35. 20b is sandwiched and pulled by the pair of collection rollers 36, and stored in the collection box 37 for collection.

図5及び図6(a),(b)に示すように、カバー部材33の下面、すなわちカバー部材33のテープ通路31aと上下に対向する面には押圧部材50が設けられている。この押圧部材50はその後端部がカバー部材33の下面に片持ち固定された板ばね状の部材から成り、カバー部材33がフィーダ本体31に対して閉じてテープ通路31a上のテープ部材20を上方から覆った状態では、押圧部材50の前端部がカバー部材33の下面に接触し、押圧部材50の中間部がテープ通路31aに上方から接触することで、テープ通路31a上のテープ部材20をテープ通路31aに押し付ける(図6(b))。   As shown in FIGS. 5 and 6A and 6B, a pressing member 50 is provided on the lower surface of the cover member 33, that is, the surface of the cover member 33 that faces the tape passage 31a in the vertical direction. The pressing member 50 is a leaf spring-like member whose rear end is cantilevered to the lower surface of the cover member 33. The cover member 33 is closed with respect to the feeder body 31, and the tape member 20 on the tape passage 31a is moved upward. In the state covered, the front end portion of the pressing member 50 is in contact with the lower surface of the cover member 33, and the intermediate portion of the pressing member 50 is in contact with the tape passage 31a from above, whereby the tape member 20 on the tape passage 31a is taped. Press against the passage 31a (FIG. 6B).

このように、本実施の形態におけるテープフィーダ12では、カバー部材33のテープ通路31aと上下に対向する面に設けられた押圧部材50によって、テープ通路31a上のテープ部材20がテープ通路31aに押し付けられので、トップテープ20bの摩擦係数が小さい場合や、ベーステープ20aの厚さが薄い場合であっても、トップテープ20bに付与されるテンションによってスプロケット32が回転方向に動いてしまうことが防止される。なお、押圧部材50には、カバー部材33がフィーダ本体31に対して閉じている状態(押圧部材50がテープ通路31a上のテープ部材20をテープ通路31aに押し付けている状態)において、押圧部材50がスプロケット32の突起32bとの干渉を避けるための孔51がフィーダ本体31の前後方向に延びて設けられている(図5及び図6(a),(b))。   As described above, in the tape feeder 12 according to the present embodiment, the tape member 20 on the tape path 31a is pressed against the tape path 31a by the pressing member 50 provided on the surface of the cover member 33 facing the tape path 31a in the vertical direction. Therefore, even when the friction coefficient of the top tape 20b is small or the thickness of the base tape 20a is thin, the sprocket 32 is prevented from moving in the rotation direction due to the tension applied to the top tape 20b. The The pressing member 50 is in a state where the cover member 33 is closed with respect to the feeder body 31 (the pressing member 50 presses the tape member 20 on the tape passage 31a against the tape passage 31a). A hole 51 for avoiding interference with the protrusion 32b of the sprocket 32 is provided extending in the front-rear direction of the feeder body 31 (FIGS. 5 and 6A, 6B).

図4及び図7において、フィーダ本体31の前後方向の中間部の上部には光学センサ部61が設けられている。光学センサ部61は、フィーダ本体31に固定されたフレーム下部62a、フレーム下部62aから上方に延びた支柱部62b、支柱部62bの上端に設けられたフレーム上部62cから成るセンサフレーム62と、センサフレーム62のフレーム上部62cに設けられた投光器63及びセンサフレーム62のフレーム下部62aに設けられた受光器64を有して成る。   4 and 7, an optical sensor unit 61 is provided on the upper portion of the middle portion of the feeder main body 31 in the front-rear direction. The optical sensor unit 61 includes a sensor frame 62 including a frame lower part 62a fixed to the feeder body 31, a column part 62b extending upward from the frame lower part 62a, a frame upper part 62c provided at the upper end of the column part 62b, and a sensor frame. 62 includes a light projector 63 provided on a frame upper part 62 c of the sensor 62 and a light receiver 64 provided on a frame lower part 62 a of the sensor frame 62.

図4及び図7に示すように、投光器63と受光器64はフィーダ本体31のテープ通路31a上を進行するテープ部材20の送り孔22を上下方向に挟む位置に設けられており、投光器63はフィーダ本体31のテープ通路31a上を進行するテープ部材20の送り孔22の移動経路VL上に検査光61Lを投光し、投光器63が投光する検査光61Lを受光した受光器64は受光信号を制御装置17の判断部17aに出力する。本実施の形態では、フィーダ本体31にテープ部材送り機構が2組設けられているため、光学センサ部61を構成する投光器63及び受光器64も2組設けられている(図4)。   As shown in FIGS. 4 and 7, the projector 63 and the light receiver 64 are provided at positions where the feed hole 22 of the tape member 20 traveling on the tape passage 31 a of the feeder body 31 is sandwiched in the vertical direction. A light receiver 64 that projects the inspection light 61L onto the moving path VL of the feed hole 22 of the tape member 20 traveling on the tape passage 31a of the feeder body 31 and receives the inspection light 61L emitted by the light projector 63 is a light reception signal. Is output to the determination unit 17 a of the control device 17. In the present embodiment, since two sets of tape member feeding mechanisms are provided in the feeder main body 31, two sets of the projector 63 and the light receiver 64 constituting the optical sensor unit 61 are also provided (FIG. 4).

テープ通路31a上をテープ部材20が進行している状態では、投光器63が投光する検査光61Lはテープ部材20の送り孔22によって一定時間間隔で横切られるために、受光器64による検査光61Lの受光状態は周期的に断続するが、連結部材20Gによってスプライシングされたテープ部材20の連結部が検査光61Lを横切っている間は、スプロケット32が回転動作を行っているにも拘らず受光器64による検査光61Lの受光状態が周期的に断続しない(非受光状態が継続する)。このため制御装置17の判断部17aは、検査光61Lがスプロケット32の回転動作に応じて進行するテープ部材20の送り孔22によって周期的に断続される状態が続いた後、スプロケット32が回転動作を行っているにも拘らず検査光61Lが断続される状態が一定時間検出されなかったことを検知したときには、そのとき連結部材20Gが検査光61Lを通過したものとしてテープ部材20の連結部の位置を検出する。   In a state where the tape member 20 is traveling on the tape path 31a, the inspection light 61L emitted by the light projector 63 is crossed by the feed hole 22 of the tape member 20 at a constant time interval. The light receiving state is intermittently interrupted. However, while the connecting portion of the tape member 20 spliced by the connecting member 20G crosses the inspection light 61L, the light receiver is in spite of the rotation of the sprocket 32. 64 is not periodically interrupted (the non-light receiving state continues). Therefore, the determination unit 17a of the control device 17 causes the sprocket 32 to rotate after the inspection light 61L continues to be periodically interrupted by the feed hole 22 of the tape member 20 that travels according to the rotation of the sprocket 32. When it is detected that the state in which the inspection light 61L is intermittent is not detected for a certain period of time despite the fact that the inspection light 61L is being performed, the connection member 20G is assumed to have passed the inspection light 61L at that time and the connection portion of the tape member 20 Detect position.

すなわち、本実施の形態において、光学センサ部61と制御装置17の判断部17aは、フィーダ本体31のテープ通路31a上を進行するテープ部材20の送り孔22の移動経路VL上に検査光61Lを射出し、その射出した検査光61Lをテープ部材20の送り孔22が横切る状態が変化したことに基づいてテープ部材20の連結部を検出する連結部検出装置となっている。   That is, in this embodiment, the optical sensor unit 61 and the determination unit 17a of the control device 17 emit the inspection light 61L on the moving path VL of the feed hole 22 of the tape member 20 that travels on the tape path 31a of the feeder body 31. The connecting portion detecting device detects the connecting portion of the tape member 20 based on the fact that the inspection light 61L is emitted and the state in which the feed hole 22 of the tape member 20 crosses is changed.

なお、図2に示すように、連結部材20Gには送り孔22の並びに沿って厚さ方向に貫通する溝20Sが設けられており、連結部材20Gによって覆われた送り孔22内に下方から入り込んだスプロケット32の突起32bはこの溝20Sを通り抜けて送り孔22に係合するので、連結部材20Gがスプロケット32によるテープ部材20の進行動作の妨げとなることはない。   As shown in FIG. 2, the connecting member 20G is provided with a groove 20S penetrating in the thickness direction along the feed hole 22, and enters the feed hole 22 covered by the connecting member 20G from below. Since the protrusion 32b of the sprocket 32 passes through the groove 20S and engages with the feed hole 22, the connecting member 20G does not hinder the advancing operation of the tape member 20 by the sprocket 32.

図3及び図4において、フィーダ本体31の中間部の上部にはテープ移動規制部材70が設けられている。このテープ移動規制部材70は、連結部検出装置の投光器63が射出する検査光61Lがテープ部材20の送り孔22の移動経路VLと交わる箇所P(図7)におけるテープ部材20の幅方向(テープ部材20の進行方向と直交する方向(X軸方向))の移動を規制するものである。   3 and 4, a tape movement restricting member 70 is provided at the upper part of the intermediate portion of the feeder main body 31. This tape movement restricting member 70 is formed in the width direction of the tape member 20 at the point P (FIG. 7) where the inspection light 61L emitted from the light projector 63 of the connecting portion detection device intersects the movement path VL of the feed hole 22 of the tape member 20 The movement of the member 20 in the direction orthogonal to the traveling direction (X-axis direction) is restricted.

図8(a),(b)において、テープ移動規制部材70は、水平に広がって延びた水平部71及び水平部71のX軸方向の両端部から下方に延びて設けられた2つの側壁部72を有して成り、2つの側壁部72の下端がフィーダ本体31の側面の溝部31b(図9(a),(b))に係合することによってフィーダ本体31に着脱自在に取り付けられる。図8(a),(b)及び図9(a),(b)に示すように、水平部71には、2つの側壁部72がフィーダ本体31の溝部31bに係合した状態でフィーダ本体31の前後方向に延びる切り欠き部73が設けられている。この切り欠き部73はセンサフレーム62の支柱部62bの幅寸法よりも若干大きい幅を有しており、2つの側壁部72をフィーダ本体31の溝部31bに係合させた後、2つの側壁部72を溝部31b上で滑らせるようにしてフィーダ本体31の全体を前方に移動させることにより、切り欠き部73をセンサフレーム62の支柱部62bに係合させてテープ移動規制部材70を安定的にフィーダ本体31に取り付けることができる(図9(a)→図9(b))。   8A and 8B, the tape movement restricting member 70 includes a horizontal portion 71 extending horizontally and two side wall portions provided extending downward from both ends of the horizontal portion 71 in the X-axis direction. 72, and the lower ends of the two side wall portions 72 are detachably attached to the feeder main body 31 by engaging the groove portions 31b (FIGS. 9A and 9B) on the side surface of the feeder main body 31. As shown in FIGS. 8A and 8B and FIGS. 9A and 9B, the horizontal portion 71 has a feeder main body with two side wall portions 72 engaged with the groove 31b of the feeder main body 31. 31 is provided with a notch 73 extending in the front-rear direction. The notch 73 has a width that is slightly larger than the width of the support 62b of the sensor frame 62. After engaging the two side walls 72 with the groove 31b of the feeder body 31, the two side walls 72, the entire feeder main body 31 is moved forward by sliding on the groove 31b, whereby the notch 73 is engaged with the column 62b of the sensor frame 62, and the tape movement regulating member 70 is stably provided. It can be attached to the feeder body 31 (FIG. 9 (a) → FIG. 9 (b)).

ここで、図8(a),(b)に示すように、テープ移動規制部材70の水平部71の切り欠き部73を挟む2箇所には、テープ移動規制部材70がフィーダ本体31に取り付けられた状態で投光器63が透光する検査光61Lが通過する検査光通過孔74が設けられており、テープ移動規制部材70がフィーダ本体31に取り付けられた状態であっても光学センサ部61によるテープ部材20の送り孔22の検出が妨げられることがないようになっている。   Here, as shown in FIGS. 8A and 8B, the tape movement restriction member 70 is attached to the feeder main body 31 at two positions sandwiching the notch 73 of the horizontal portion 71 of the tape movement restriction member 70. The inspection light passage hole 74 through which the inspection light 61L transmitted through the projector 63 passes is provided, and the tape by the optical sensor unit 61 is provided even when the tape movement restriction member 70 is attached to the feeder body 31. The detection of the feed hole 22 of the member 20 is not hindered.

テープ移動規制部材70がフィーダ本体31に取り付けられると、テープ移動規制部材70の2つの側壁部72はテープ部材20が確実にテープ通路31a上を進行するようにテープ部材20を案内するガイド部材として機能し、これによりテープ部材20がテープ通路31aから外れて進行することが防止される。このため、連結部検出装置の投光器63の取り付け位置に設計上の位置からの誤差が生じ、検査光61Lの射出位置が設定された設計上の位置から幾分ずれている場合であっても、テープ通路31a上を進行するテープ部材20の送り孔22が確実に検査光61Lを横切るようにすることができる。   When the tape movement restricting member 70 is attached to the feeder main body 31, the two side wall portions 72 of the tape movement restricting member 70 serve as guide members for guiding the tape member 20 so that the tape member 20 surely advances on the tape path 31a. This prevents the tape member 20 from moving away from the tape passage 31a. For this reason, even if the error from the design position occurs in the mounting position of the projector 63 of the connecting portion detection device, and the emission position of the inspection light 61L is somewhat deviated from the set design position, It is possible to ensure that the feed hole 22 of the tape member 20 traveling on the tape path 31a crosses the inspection light 61L.

図1において、ベルトコンベア11による基板2の搬送及び位置決め動作は、制御装置17がベルトコンベア11の作動制御を行うことによってなされ、各テープフィーダ12による部品取り出し口33aへの部品4の供給動作は、制御装置17が前述のスプロケット駆動モータ41及びローラ駆動モータ33cの作動制御を行うことによってなされる。   In FIG. 1, the conveyance and positioning operation of the substrate 2 by the belt conveyor 11 is performed by the control device 17 controlling the operation of the belt conveyor 11, and the operation of supplying the component 4 to the component extraction port 33 a by each tape feeder 12 is performed. The control device 17 performs the operation control of the sprocket drive motor 41 and the roller drive motor 33c described above.

図1において、装着ヘッド14の移動動作は、制御装置17が前述のヘッド移動ロボット13の作動制御を行うことによってなされ、装着ヘッド14に設けられた吸着ノズル14aの装着ヘッド14に対する昇降及び上下軸回りの回転動作は、制御装置17が前述のノズル駆動機構18の作動制御を行うことによってなされる。また、各吸着ノズル14aによる部品4の吸着とその吸着解除動作は、制御装置17が前述の吸着機構19の作動制御を行うことによってなされる。このように装着ヘッド14は、各テープフィーダ12の部品取り出し口33aに供給された部品をピックアップしてベルトコンベア11により位置決めされた基板2に装着するものとなっている。   In FIG. 1, the movement operation of the mounting head 14 is performed by the control device 17 performing the operation control of the head moving robot 13 described above. The suction nozzle 14 a provided in the mounting head 14 is moved up and down with respect to the mounting head 14 and the vertical axis. The rotating operation is performed when the control device 17 controls the operation of the nozzle drive mechanism 18 described above. Further, the suction of the component 4 by the suction nozzles 14a and the suction release operation thereof are performed by the control device 17 performing the operation control of the suction mechanism 19 described above. As described above, the mounting head 14 picks up the components supplied to the component take-out port 33 a of each tape feeder 12 and mounts the components on the substrate 2 positioned by the belt conveyor 11.

図1において、基板カメラ15による撮像動作の制御と部品カメラ16による撮像動作の制御は制御装置17によってなされ、基板カメラ15及び部品カメラ16の撮像動作によって得られた画像データは制御装置17に入力され、制御装置17が備える画像認識部17bにおいて画像認識処理がなされる。なお、基板カメラ15の移動は、制御装置17がヘッド移動ロボット13の作動制御を行って装着ヘッド14を移動させることよってなされる。   In FIG. 1, the control of the imaging operation by the substrate camera 15 and the imaging operation by the component camera 16 are performed by the control device 17, and image data obtained by the imaging operations of the substrate camera 15 and the component camera 16 are input to the control device 17. Then, image recognition processing is performed in the image recognition unit 17b included in the control device 17. The substrate camera 15 is moved by the control device 17 moving the mounting head 14 by controlling the operation of the head moving robot 13.

このような構成の部品実装装置1により、基板2上の電極部3に部品4を装着する部品実装作業(部品実装方法)を実行するには、制御装置17は先ず、ベルトコンベア11を作動させ、部品実装装置1の上流工程側の装置から送られてきた基板2を受け取って部品実装装置1の内部に搬入し、所定の作業位置に位置決めする(図10に示すステップST1の基板位置決め工程)。   In order to execute a component mounting operation (component mounting method) for mounting the component 4 on the electrode 3 on the substrate 2 by the component mounting apparatus 1 having such a configuration, the control device 17 first operates the belt conveyor 11. Then, the board 2 sent from the apparatus on the upstream process side of the component mounting apparatus 1 is received, carried into the component mounting apparatus 1, and positioned at a predetermined work position (board positioning process of step ST1 shown in FIG. 10). .

制御装置17は、基板2の位置決めを行ったら、装着ヘッド14を移動させて基板カメラ15を基板2の上方に移動させ、基板カメラ15に基板2上の一対の基板マーク2m(図1)の撮像を行わせて画像認識する。そして、得られた一対の基板マーク2mの位置を予め設定された基準の位置と比較することによって、基板2の基準の位置からの位置ずれを算出する(図10に示すステップST2の基板位置ずれ算出工程)。   After positioning the substrate 2, the control device 17 moves the mounting head 14 to move the substrate camera 15 above the substrate 2, and the substrate camera 15 moves the pair of substrate marks 2 m (FIG. 1) on the substrate 2. Image recognition is performed by performing imaging. Then, the positional deviation of the substrate 2 from the reference position is calculated by comparing the obtained position of the pair of substrate marks 2m with a preset reference position (the substrate positional deviation of step ST2 shown in FIG. 10). Calculation step).

制御装置17は、基板2の基準の位置からの位置ずれを算出したら、テープフィーダ12の作動制御を行ってそのテープフィーダ12の部品取り出し口33aに部品4を供給するとともに(図10に示すステップST3の部品供給工程)、装着ヘッド14をテープフィーダ12の上方に位置させたうえで(図3)、テープフィーダ12の部品取り出し口33aに供給された部品4をピックアップ(吸着)させる(図10に示すステップST4の部品ピックアップ工程)。   When the controller 17 calculates the positional deviation of the substrate 2 from the reference position, the controller 17 controls the operation of the tape feeder 12 to supply the component 4 to the component take-out port 33a of the tape feeder 12 (step shown in FIG. 10). (ST3 component supply step) After the mounting head 14 is positioned above the tape feeder 12 (FIG. 3), the component 4 supplied to the component take-out port 33a of the tape feeder 12 is picked up (sucked) (FIG. 10). Step ST4 shown in FIG.

上記部品供給工程において、テープ部材20の連結部が連結部検出装置の投光器63が投光する検査光61Lを横切ったときには制御装置17の判断部17aがこれを検出し、その検出したテープ部材20の連結部の位置の情報は、制御装置17による部品4のロット管理等に利用される。また、上記部品供給工程において、テープ部材20はカバー部材33に設けられた押圧部材50によってフィーダ本体31のテープ通路31aに押し付けられるので、部品4は供給ずれを生じることなくテープフィーダ12の部品取り出し口33aに供給される。   In the component supply step, when the connecting portion of the tape member 20 crosses the inspection light 61L projected by the projector 63 of the connecting portion detecting device, the determination portion 17a of the control device 17 detects this, and the detected tape member 20 is detected. The information on the position of the connecting portion is used for the lot management of the parts 4 by the control device 17. In the component supply step, the tape member 20 is pressed against the tape passage 31a of the feeder main body 31 by the pressing member 50 provided on the cover member 33, so that the component 4 is removed from the tape feeder 12 without causing a supply shift. It is supplied to the mouth 33a.

制御装置17は、吸着ノズル14aに部品4をピックアップさせたら、その部品4が部品カメラ16の上方を通過するように装着ヘッド14を移動させ、部品カメラ16に部品4の撮像を行わせて画像認識を行い(図10に示すステップST5の画像認識工程)、部品4の吸着ノズル14aに対する位置ずれ(吸着ずれ)を算出する(図10に示すステップST6の吸着ずれ算出工程)。   When the control device 17 causes the suction nozzle 14 a to pick up the component 4, the control device 17 moves the mounting head 14 so that the component 4 passes above the component camera 16, and causes the component camera 16 to capture the component 4. Recognition is performed (image recognition process in step ST5 shown in FIG. 10), and a positional shift (suction shift) of the component 4 with respect to the suction nozzle 14a is calculated (a suction shift calculation process in step ST6 shown in FIG. 10).

制御装置17は、部品4の吸着ノズル14aに対する位置ずれを算出したら、装着ヘッド14を基板2の上方に位置させ、吸着ノズル14aによりピックアップした部品4を基板2上の電極部3に接触させたうえで吸着ノズル14aへの真空圧の供給を解除し、部品4を基板2に装着する(図10に示すステップST7の部品装着工程)。この部品装着工程では、制御装置17は、ステップST2で求めた基板2の位置ずれと、ステップST6で求めた部品4の吸着ずれが修正されるように、基板2に対する吸着ノズル14aの位置補正(回転補正を含む)を行う。   After calculating the positional deviation of the component 4 relative to the suction nozzle 14a, the control device 17 positions the mounting head 14 above the substrate 2 and brings the component 4 picked up by the suction nozzle 14a into contact with the electrode portion 3 on the substrate 2. Then, the supply of the vacuum pressure to the suction nozzle 14a is released, and the component 4 is mounted on the substrate 2 (component mounting step of step ST7 shown in FIG. 10). In this component mounting process, the control device 17 corrects the position of the suction nozzle 14a relative to the substrate 2 so that the positional deviation of the substrate 2 obtained in step ST2 and the suction deviation of the component 4 obtained in step ST6 are corrected. (Including rotation correction).

制御装置17は、基板2に対する部品4の装着を行ったら、基板2に装着すべき全ての部品4の装着が終了したか否かの判断を行う(図10に示すステップST8の第1の判断工程)。そして、基板2に装着すべき全ての部品4の装着が終了していなかったときにはステップST4に戻って吸着ノズル14aによる次の部品4のピックアップを行い、基板2に装着すべき全ての部品4の装着が終了していたときには、ベルトコンベア11を作動させて基板2を部品実装装置1から搬出する(図10に示すステップST9の基板搬出工程)。   After mounting the components 4 on the board 2, the control device 17 determines whether or not all the components 4 to be mounted on the board 2 have been mounted (first determination in step ST8 shown in FIG. 10). Process). When the mounting of all the components 4 to be mounted on the substrate 2 has not been completed, the process returns to step ST4 to pick up the next component 4 by the suction nozzle 14a, and all the components 4 to be mounted on the substrate 2 are picked up. When the mounting is completed, the belt conveyor 11 is operated to carry out the board 2 from the component mounting apparatus 1 (board carrying-out process in step ST9 shown in FIG. 10).

制御装置17は、基板2を搬出したら、次いで、まだ部品4の装着を行うべき基板2があるかどうかの判断を行う(図10に示すステップST10の第2の判断工程)。そして、部品4の装着を行うべき基板2があった場合にはステップST1に戻り、部品4の装着を行うべき基板2がなかった場合には、一連の作業を終了する。   After carrying out the board 2, the control device 17 then judges whether there is still the board 2 on which the component 4 is to be mounted (second judgment step of step ST <b> 10 shown in FIG. 10). If there is a board 2 on which the component 4 is to be mounted, the process returns to step ST1, and if there is no board 2 on which the component 4 is to be mounted, a series of operations is terminated.

以上説明したように、本実施の形態における部品実装装置1では、テープフィーダ12のフィーダ本体31に設けられたテープ移動規制部材70によって、連結部検出装置の投光器63が射出する検査光61Lがテープ部材20の送り孔22の移動経路VLと交わる箇所Pにおけるテープ部材20の幅方向(テープ部材20の進行方向と直交する方向)の移動が規制されるようになっており、検査光61Lの射出位置が設定された設計上の位置から幾分ずれている場合であっても、テープ通路31a上を進行するテープ部材20の送り孔22が確実に検査光61Lを横切るようにすることができるので、テープ部材20の連結部(連結部材20G)の誤検出を防いでこれによる不具合の発生を抑えることができる。   As described above, in the component mounting apparatus 1 according to the present embodiment, the inspection light 61L emitted from the light projector 63 of the connecting portion detection device is the tape by the tape movement restriction member 70 provided in the feeder main body 31 of the tape feeder 12. The movement of the tape member 20 in the width direction (direction perpendicular to the traveling direction of the tape member 20) at a position P that intersects the movement path VL of the feed hole 22 of the member 20 is restricted, and the inspection light 61L is emitted. Even if the position is somewhat deviated from the set design position, the feed hole 22 of the tape member 20 traveling on the tape path 31a can be surely crossed the inspection light 61L. In addition, it is possible to prevent erroneous detection of the connecting portion (connecting member 20G) of the tape member 20 and suppress the occurrence of problems due to this.

なお、上記テープ移動規制部材70は、フィーダ本体31に設けられ、連結部検出装置が射出する検査光61Lがテープ部材20の送り孔22の移動経路VLと交わる箇所Pにおけるテープ部材20の幅方向(テープ部材20の進行方向と直交する方向)の移動を規制するものであればよく、必ずしも上述した形態のものに限定されない。また、テープ移動規制部材70はフィーダ本体31に対して着脱自在になっていなくてもよい。   The tape movement regulating member 70 is provided in the feeder main body 31, and the width direction of the tape member 20 at the point P where the inspection light 61L emitted from the connecting portion detection device intersects the movement path VL of the feed hole 22 of the tape member 20 is provided. What is necessary is just to restrict | limit the movement of (the direction orthogonal to the advancing direction of the tape member 20), and it is not necessarily limited to the thing of the form mentioned above. Further, the tape movement regulating member 70 may not be detachable from the feeder main body 31.

テープ部材の連結部の誤検出による不具合の発生を抑えることができるテープフィーダ及び部品実装装置を提供する。   Provided are a tape feeder and a component mounting apparatus capable of suppressing the occurrence of problems due to erroneous detection of a connecting portion of tape members.
