Description

本発明は、部品を保持したキャリヤテープを走行させて部品供給位置に部品を供給するテープフィーダに関するものである。 The present invention relates to a tape feeder that runs a carrier tape holding a component to supply the component to a component supply position.

従来、部品実装装置における代表的な部品供給装置の一つとしてテープフィーダが知られている。部品実装装置は、吸着ノズルにより部品を吸着して基板に装着する装置であり、テープフィーダは、部品を保持したキャリヤテープをテープ走行機構によって走行させることで、吸着ノズルによる部品の吸着位置である部品供給位置に部品を位置させる。部品供給位置の近傍領域のキャリヤテープはテープ押さえ部材によって上方から押さえられており、部品はテープ押さえ部材に設けられた部品供給開口から吸着ノズルによって吸着して取り出される。キャリヤテープのカバーテープは、剥離されて部品供給開口から引き出される。カバーテープの剥離の際に発生する静電気の影響や、キャリヤテープの搬送時の衝撃によって部品がキャリヤテープから飛び出してしまうことがある。このため、部品供給位置を走行するキャリヤテープの下方に磁石部材を設け、磁石部材の磁力によって部品を下方に引き寄せるようにしたものが知られている（例えば、下記の特許文献１）。この場合、磁石部材の磁力は、吸着ノズルによる部品の吸着が妨げられない程度に設定される。 Conventionally, a tape feeder is known as one of the typical component supply devices in a component mounting device. The component mounting device is a device that sucks the component by the suction nozzle and mounts it on the substrate, and the tape feeder is the suction position of the component by the suction nozzle by running the carrier tape holding the component by the tape traveling mechanism. Position the parts at the parts supply position. The carrier tape in the region near the component supply position is pressed from above by the tape holding member, and the component is sucked and taken out by the suction nozzle from the component supply opening provided in the tape holding member. The cover tape of the carrier tape is peeled off and pulled out from the component supply opening. Parts may pop out of the carrier tape due to the influence of static electricity generated when the cover tape is peeled off or the impact during transportation of the carrier tape. For this reason, it is known that a magnet member is provided below the carrier tape traveling at the component supply position so that the component is attracted downward by the magnetic force of the magnet member (for example, Patent Document 1 below). In this case, the magnetic force of the magnet member is set to such an extent that the suction of the component by the suction nozzle is not hindered.

また、近年、部品のサイズが一段と小さくなってきており、カバーテープを部品供給開口から引き出す際、静電気の影響で部品がカバーテープに付着してしまい、キャリヤテープ内から部品が脱落してしまう場合がある。このため、部品供給開口よりもキャリヤテープの走行方向の上流側の位置にスリットを設け、このスリットからカバーテープを引き出す「事前剥離」を行うことによって、静電気の影響でカバーテープに付着した部品がキャリヤテープから脱落しないようにしたものが知られている。 Further, in recent years, the size of parts has become smaller and smaller, and when the cover tape is pulled out from the parts supply opening, the parts adhere to the cover tape due to the influence of static electricity, and the parts fall off from the carrier tape. There is. For this reason, a slit is provided at a position on the upstream side of the carrier tape in the traveling direction from the component supply opening, and the cover tape is pulled out from this slit by "pre-peeling" so that the component attached to the cover tape due to the influence of static electricity can be removed. It is known that the carrier tape is prevented from falling off.

しかしながら、上記のように事前剥離をする場合であっても、部品のサイズが極めて小さい場合には、静電気でカバーテープに付着した部品がスリットから飛び出し、スリットに噛み込まれたりするなどの事態が生じるおそれがあった。 However, even in the case of pre-peeling as described above, if the size of the part is extremely small, the part attached to the cover tape due to static electricity may pop out from the slit and be bitten into the slit. There was a risk of it occurring.

このため本発明は、事前剥離の際、静電気でカバーテープに付着した部品がスリットから飛び出してしまう事態を防止でき、安定した部品供給動作を実現することができるテープフィーダを提供することを目的とする。 Therefore, an object of the present invention is to provide a tape feeder capable of preventing a component adhering to the cover tape from popping out from the slit during pre-peeling and realizing a stable component supply operation.

以下、図面を参照して本発明の実施の形態について説明する。図１に示す部品実装装置１は基板２に部品３を実装する装置であり、基台１１上に基板搬送部１２と部品装着部１３を備えている。基台１１には台車１４で移動されるフィーダベース１５が連結されており、フィーダベース１５にはテープフィーダ１６が取り付けられている（図２）。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The component mounting device 1 shown in FIG. 1 is a device for mounting a component 3 on a substrate 2, and includes a substrate transport unit 12 and a component mounting unit 13 on a base 11. A feeder base 15 moved by a carriage 14 is connected to the base 11, and a tape feeder 16 is attached to the feeder base 15 (FIG. 2).

図１において、基板搬送部１２はＹ軸方向（作業者ＯＰから見た前後方向）に配置された一対のコンベア１２ａを備えて成り、基板２をＸ軸方向（作業者ＯＰから見た左右方向）に搬送する。部品装着部１３は吸着ノズル１３ａを備えた装着ヘッド１３ｂと、装着ヘッド１３ｂを水平面内方向に移動させるヘッド移動機構１３ｃから構成されている。装着ヘッド１３ｂは吸着ノズル１３ａをＺ軸方向（上下方向）に移動させることができるとともに、Ｚ軸回りに回転させることができる。 In FIG. 1, the substrate transport unit 12 includes a pair of conveyors 12a arranged in the Y-axis direction (front-back direction as seen from the worker OP), and the substrate 2 is in the X-axis direction (left-right direction as seen from the worker OP). ). The component mounting portion 13 is composed of a mounting head 13b provided with a suction nozzle 13a and a head moving mechanism 13c for moving the mounting head 13b in the horizontal plane direction. The mounting head 13b can move the suction nozzle 13a in the Z-axis direction (vertical direction) and can rotate it around the Z-axis.

フィーダベース１５には複数のテープフィーダ１６がＸ軸方向に並んで取り付けられている。図１に示すように、各テープフィーダ１６には台車１４に保持されたリール１７から引き出されたキャリヤテープ１８が導入されており（図２も参照）、各テープフィーダ１６は、キャリヤテープ１８をピッチ送りすることで、キャリヤテープ１８に保持された部品３を、吸着ノズル１３ａによる部品３の吸着位置である部品供給位置１６Ｋに間欠的に供給する。 A plurality of tape feeders 16 are attached to the feeder base 15 side by side in the X-axis direction. As shown in FIG. 1, each tape feeder 16 is introduced with a carrier tape 18 drawn from a reel 17 held by a carriage 14 (see also FIG. 2), and each tape feeder 16 has a carrier tape 18 By pitch feeding, the component 3 held by the carrier tape 18 is intermittently supplied to the component supply position 16K, which is the suction position of the component 3 by the suction nozzle 13a.

キャリヤテープ１８は、図３に示すように、ベーステープ２１の上面に透明のカバーテープ２２が貼り付けられた構成を有している。ベーステープ２１には複数の部品収納部２３が一列に並んで設けられており、各部品収納部２３には部品３が収納されている。カバーテープ２２は各部品収納部２３を上方から覆っており、部品収納部２３からの部品３の脱落を防止している。ベーステープ２１の部品収納部２３の列と平行な位置には送り孔２４が一列に並んで設けられている。 As shown in FIG. 3, the carrier tape 18 has a configuration in which a transparent cover tape 22 is attached to the upper surface of the base tape 21. A plurality of component storage units 23 are provided side by side in a row on the base tape 21, and the component 3 is stored in each component storage unit 23. The cover tape 22 covers each component storage unit 23 from above to prevent the component 3 from falling off from the component storage unit 23. Feed holes 24 are provided in a row at positions parallel to the row of component storage portions 23 of the base tape 21.

テープフィーダ１６は、図２及び図４に示すように、フィーダベース１５に着脱自在に取り付けられる本体部３１に、テープ走行機構３２、テープ押さえ部材３３及びカバーテープ回収機構３４を備えている。本体部３１には、キャリヤテープ１８が走行するテープ走行面３５が形成されている。テープ走行面３５は、本実施の形態では、本体部３１の後端下部に形成されたテープ導入口３１Ｇ（図２及び図４）から前方に水平に延びた後、本体部３１の中間部で前上方へ向けて斜めに延び、本体部３１の上面に露出した状態で本体部３１の前方に延びている。 As shown in FIGS. 2 and 4, the tape feeder 16 includes a tape traveling mechanism 32, a tape holding member 33, and a cover tape collecting mechanism 34 in a main body portion 31 that is detachably attached to the feeder base 15. A tape running surface 35 on which the carrier tape 18 runs is formed on the main body 31. In the present embodiment, the tape running surface 35 extends horizontally forward from the tape introduction port 31G (FIGS. 2 and 4) formed in the lower part of the rear end of the main body portion 31 and then at the intermediate portion of the main body portion 31. It extends diagonally forward and upward, and extends forward of the main body 31 in a state of being exposed on the upper surface of the main body 31.

図２及び図４において、テープ走行機構３２は、本体部３１の前上方の位置に設けられたスプロケット４１と、スプロケット４１をＸ軸回りに間欠的に回転駆動する駆動モータ４２を備えている。スプロケット４１はキャリヤテープ１８の送り孔２４に外周歯４１Ｔ（図３）を係合させて回転することにより、テープ走行面３５上でキャリヤテープ１８をピッチ送りする（図２及び図４中に示す矢印Ａ）。これによりキャリヤテープ１８は、部品収納部２３を（すなわち部品３を）部品供給位置１６Ｋに間欠的に位置させる。 In FIGS. 2 and 4, the tape traveling mechanism 32 includes a sprocket 41 provided at a position in front of and above the main body 31, and a drive motor 42 for intermittently rotating and driving the sprocket 41 around the X axis. The sprocket 41 rotates by engaging the outer peripheral teeth 41T (FIG. 3) with the feed hole 24 of the carrier tape 18, so that the carrier tape 18 is pitch-fed on the tape running surface 35 (shown in FIGS. 2 and 4). Arrow A). As a result, the carrier tape 18 intermittently positions the component storage portion 23 (that is, the component 3) at the component supply position 16K.

図２及び図４において、テープ押さえ部材３３は本体部３１の前上方の位置に前後方向に延びて設けられている。テープ押さえ部材３３は、テープ走行面３５を走行するキャリヤテープ１８のうち、スプロケット４１の外周歯４１Ｔが係合する部分の近傍領域（すなわち部品供給位置１６Ｋの近傍領域）を覆っており、その部分のキャリヤテープ１８を上方から押さえている。図５に示すように、テープ押さえ部材３３には、部品供給位置１６Ｋに位置した部品収納部２３の上方を開放するように設けられた部品供給開口３３Ｔと、剥離されたカバーテープ２２を引き出すためのスリット３３Ｓと、スプロケット４１の外周歯４１Ｔとの干渉を避けるための溝部３３Ｍが設けられている。スリット３３Ｓは部品供給開口３３Ｔの後方に位置している。 In FIGS. 2 and 4, the tape holding member 33 is provided so as to extend in the front-rear direction at a position in front of and above the main body portion 31. The tape holding member 33 covers a region (that is, a region near the component supply position 16K) of the carrier tape 18 traveling on the tape traveling surface 35 where the outer peripheral teeth 41T of the sprocket 41 are engaged. Carrier tape 18 is pressed from above. As shown in FIG. 5, the tape holding member 33 has a component supply opening 33T provided so as to open above the component storage portion 23 located at the component supply position 16K, and a peeled cover tape 22 for pulling out. A groove 33M is provided for avoiding interference between the slit 33S of the sprocket 41 and the outer peripheral teeth 41T of the sprocket 41. The slit 33S is located behind the component supply opening 33T.

ここで、カバーテープ２２は、その先頭側の一部が作業者ＯＰによって予めベーステープ２１から剥離されたうえでスリット３３Ｓから後上方に引き出されており（図２及び図５）、本体部３１の中間部の上方位置に設けられたカバーテープ回収機構３４に導かれている。カバーテープ回収機構３４は、テープ走行機構３２がキャリヤテープ１８をピッチ送りするのに応じて間欠的にカバーテープ２２を引っ張り（図２、図４及び図５中に示す矢印Ｂ）、本体部３１内の後部に形成されたカバーテープ収容部３６内に収容する。このためカバーテープ２２はスリット３３Ｓを剥離位置としてベーステープ２１から剥離され、部品収納部２３が部品供給位置１６Ｋに到達した時点で部品収納部２３はカバーテープ２２によって覆われていない露出状態となる。これにより装着ヘッド１３ｂは、部品供給位置１６Ｋに位置した部品３を吸着ノズル１３ａにより吸着することができる。 Here, a part of the leading side of the cover tape 22 is peeled off from the base tape 21 in advance by the operator OP and then pulled out from the slit 33S rearward and upward (FIGS. 2 and 5), and the main body 31 It is guided to a cover tape collecting mechanism 34 provided at an upper position in the middle portion of the above. The cover tape collecting mechanism 34 intermittently pulls the cover tape 22 in response to the tape traveling mechanism 32 pitch-feeding the carrier tape 18 (arrow B shown in FIGS. 2, 4 and 5), and the main body 31 It is housed in the cover tape housing part 36 formed at the rear part of the inside. Therefore, the cover tape 22 is peeled off from the base tape 21 with the slit 33S as the peeling position, and when the component storage section 23 reaches the component supply position 16K, the component storage section 23 is in an exposed state not covered by the cover tape 22. .. As a result, the mounting head 13b can suck the component 3 located at the component supply position 16K by the suction nozzle 13a.

図６において、本体部３１の上面のうち、テープ押さえ部材３３によって覆われる部分にはテープ下受け部材５０が設けられている。テープ下受け部材５０は、テープ押さえ部材３３によって上方から押さえられるキャリヤテープ１８の下面を下受けする。 In FIG. 6, a tape underlay member 50 is provided on a portion of the upper surface of the main body 31 that is covered by the tape holding member 33. The tape bottom receiving member 50 receives the lower surface of the carrier tape 18 pressed from above by the tape holding member 33.

図６及び図７（ａ），（ｂ）において、テープ下受け部材５０は水平に延びる水平部５０ａと、水平部５０ａの後端部から後方斜め下方に延びた後方傾斜部５０ｂと、水平部５０ａの前端部から前方斜め下方に延びた前方傾斜部５０ｃを有している。水平部５０ａの上面はテープ走行面３５の一部を構成している。 In FIGS. 6 and 7 (a) and 7 (b), the tape underlay member 50 has a horizontal portion 50a extending horizontally, a rear inclined portion 50b extending diagonally backward and downward from the rear end portion of the horizontal portion 50a, and a horizontal portion. It has a forward inclined portion 50c extending diagonally forward and downward from the front end portion of 50a. The upper surface of the horizontal portion 50a forms a part of the tape running surface 35.

図６及び図７（ａ），（ｂ）において、テープ下受け部材５０の下方には、吸着位置側磁石５１（第１の磁石部材）とスリット側磁石５２（第２の磁石部材）が設けられている。吸着位置側磁石５１の後部の上面は水平面５１ａとなっており、前部の上面はキャリヤテープ１８の走行方向（Ｙ軸方向）の上流側から下流側に向かって（図６における紙面左方から右方に向かって）傾斜した傾斜面５１ｂとなっている。スリット側磁石５２は上面が水平面であり、その高さは吸着位置側磁石５１の後部の上面と同じ高さとなっている。 In FIGS. 6 and 7 (a) and 7 (b), a suction position side magnet 51 (first magnet member) and a slit side magnet 52 (second magnet member) are provided below the tape underlay member 50. Has been done. The upper surface of the rear portion of the suction position side magnet 51 is a horizontal plane 51a, and the upper surface of the front portion is from the upstream side to the downstream side in the traveling direction (Y-axis direction) of the carrier tape 18 (from the left side of the paper surface in FIG. 6). It has an inclined surface 51b that is inclined (to the right). The upper surface of the slit-side magnet 52 is a horizontal plane, and the height thereof is the same as the upper surface of the rear portion of the suction position-side magnet 51.

図６において、吸着位置側磁石５１は部品供給位置１６Ｋの下方に位置している。スリット側磁石５２は、吸着位置側磁石５１の後方（キャリヤテープ１８の走行方向の上流側）であって、スリット３３Ｓの下方に位置している。吸着位置側磁石５１とスリット側磁石５２とは互いに独立した別個の部材として構成されている。 In FIG. 6, the suction position side magnet 51 is located below the component supply position 16K. The slit-side magnet 52 is located behind the suction position-side magnet 51 (upstream in the traveling direction of the carrier tape 18) and below the slit 33S. The attraction position side magnet 51 and the slit side magnet 52 are configured as separate members independent of each other.

キャリヤテープ１８内の各部品３は磁石によって引き寄せられる電極部（図示せず）を有しており、吸着位置側磁石５１は部品供給位置１６Ｋに位置した部品３をテープ下受け部材５０の側（すなわち下方）に磁力で引き寄せる。スリット側磁石５２は吸着位置側磁石５１よりも大きい磁力を有しており、スリット３３Ｓの下方に位置した部品３を吸着位置側磁石５１よりも大きい磁力でテープ下受け部材５０の側（下方）に引き寄せる。 Each component 3 in the carrier tape 18 has an electrode portion (not shown) attracted by a magnet, and the suction position side magnet 51 puts the component 3 located at the component supply position 16K on the side of the tape underlay member 50 (not shown). That is, it is attracted downward) by magnetic force. The slit-side magnet 52 has a larger magnetic force than the suction position-side magnet 51, and the component 3 located below the slit 33S is placed on the side (lower side) of the tape underlay member 50 with a larger magnetic force than the suction-position-side magnet 51. Attract to.

図６において、吸着位置側磁石５１の傾斜面５１ｂの上方にはテープ下受け部材５０の水平部５０ａと前方傾斜部５０ｃの境が位置しているが、テープ下受け部材５０の水平部５０ａ上を水平前方に走行するキャリヤテープ１８は水平部５０ａを通過した後もそのまま水平方向に進む。このため、吸着位置側磁石５１の傾斜面５１ｂとキャリヤテープ１８の下面との間の距離は、キャリヤテープ１８の走行方向に（キャリヤテープ１８の走行方向の上流側から下流側に向かって）徐々に大きくなる。すなわち本実施の形態において、吸着位置側磁石５１の上面のうち、キャリヤテープ１８が部品供給位置１６Ｋを通過する前後の領域と上下に対向する部分（すなわち傾斜面５１ｂ）は、キャリヤテープ１８の走行方向の上流側から下流側に向かってキャリヤテープ１８の下面との距離が漸増するようになっている。 In FIG. 6, the boundary between the horizontal portion 50a of the tape underlaying member 50 and the forward inclined portion 50c is located above the inclined surface 51b of the suction position side magnet 51, but above the horizontal portion 50a of the tape underlaying member 50. The carrier tape 18 traveling horizontally forward travels in the horizontal direction as it is even after passing through the horizontal portion 50a. Therefore, the distance between the inclined surface 51b of the attraction position side magnet 51 and the lower surface of the carrier tape 18 gradually increases in the traveling direction of the carrier tape 18 (from the upstream side to the downstream side in the traveling direction of the carrier tape 18). Becomes larger. That is, in the present embodiment, on the upper surface of the attraction position side magnet 51, the portion (that is, the inclined surface 51b) that faces up and down with the region before and after the carrier tape 18 passes the component supply position 16K is the traveling of the carrier tape 18. The distance from the lower surface of the carrier tape 18 gradually increases from the upstream side to the downstream side in the direction.

図８は、キャリヤテープ１８内の部品３が吸着位置側磁石５１及びスリット側磁石５２から受ける磁力を、吸着位置側磁石５１及びスリット側磁石５２の上面の位置と対向する位置に応じて示したグラフである。このグラフに示すように、スリット側磁石５２の上面は、その直上に位置する領域Ｒ１内の部品３に対して一定の磁力Ｇ１を及ぼし、吸着位置側磁石５１の上面のうち水平面５１ａは、その直上に位置する領域Ｒ２内の部品３に対して一定の磁力Ｇ２を及ぼす。また、上述したように、吸着位置側磁石５１の傾斜面５１ｂは、キャリヤテープ１８の走行方向の上流側から下流側に向かってキャリヤテープ１８の下面との距離が漸増するようになっているので、吸着位置側磁石５１の上面のうち傾斜面５１ｂは、その直上に位置する領域Ｒ３内の部品３に対して、キャリヤテープ１８の走行方向に漸減する磁力を及ぼす。 FIG. 8 shows the magnetic forces received by the component 3 in the carrier tape 18 from the suction position side magnet 51 and the slit side magnet 52 according to the positions facing the upper surfaces of the suction position side magnet 51 and the slit side magnet 52. It is a graph. As shown in this graph, the upper surface of the slit side magnet 52 exerts a constant magnetic force G1 on the component 3 in the region R1 located directly above the slit side magnet 52, and the horizontal plane 51a of the upper surface of the attraction position side magnet 51 is the horizontal surface 51a. A constant magnetic force G2 is applied to the component 3 in the region R2 located directly above. Further, as described above, the inclined surface 51b of the attraction position side magnet 51 gradually increases in distance from the lower surface of the carrier tape 18 from the upstream side to the downstream side in the traveling direction of the carrier tape 18. The inclined surface 51b of the upper surface of the attraction position side magnet 51 exerts a magnetic force that gradually decreases in the traveling direction of the carrier tape 18 on the component 3 in the region R3 located immediately above the inclined surface 51b.

ここで、磁力Ｇ２は、吸着ノズル１３ａにより部品３の吸着が妨げられない程度の磁力に制限されるが、スリット側磁石５２は吸着位置側磁石５１とは独立して設けられるので、磁力Ｇ１を磁力Ｇ２よりも大きい任意の磁力に設定することができる。このため、スリット３３Ｓの下方領域の部品３を、部品供給位置１６Ｋの下方領域の部品３よりも大きい磁力でテープ下受け部材５０の側に引き寄せることができ、スリット３３Ｓの下方を通過する部品３はキャリヤテープ１８の部品収納部２３内に留められる。これにより、スリット３３Ｓによりキャリヤテープ１８のベーステープ２１からカバーテープ２２が事前剥離される際、静電気によって部品３がカバーテープ２２に付着してスリット３３Ｓから飛び出してしまう事態を防止できる。 Here, the magnetic force G2 is limited to a magnetic force that does not hinder the attraction of the component 3 by the attraction nozzle 13a, but since the slit side magnet 52 is provided independently of the attraction position side magnet 51, the magnetic force G1 is used. It can be set to any magnetic force larger than the magnetic force G2. Therefore, the component 3 in the lower region of the slit 33S can be attracted to the side of the tape underlay member 50 with a magnetic force larger than that of the component 3 in the lower region of the component supply position 16K, and the component 3 passing under the slit 33S. Is fastened in the component storage portion 23 of the carrier tape 18. As a result, when the cover tape 22 is pre-peeled from the base tape 21 of the carrier tape 18 by the slit 33S, it is possible to prevent the component 3 from adhering to the cover tape 22 due to static electricity and popping out from the slit 33S.

一方、吸着位置側磁石５１は部品供給位置１６Ｋの下方に位置しており、部品供給位置１６Ｋを通る部品３を磁力で引き寄せるため、カバーテープ２２が引き剥がされた後のベーステープ２１の部品収納部２３から部品３が飛び出る事態を防止できる。ここで、前述したように、吸着位置側磁石５１の傾斜面５１ｂがその直上に位置する部品３に及ぼす磁力は磁力Ｇ２からキャリヤテープ１８の走行方向に向けて漸減するため、吸着ノズル１３ａによる部品３の吸着が、吸着位置側磁石５１から受ける磁力によって妨げられる事態は極めて生じにくくなっている。 On the other hand, the attraction position side magnet 51 is located below the component supply position 16K, and magnetically attracts the component 3 passing through the component supply position 16K, so that the component storage of the base tape 21 after the cover tape 22 is peeled off. It is possible to prevent the component 3 from popping out from the portion 23. Here, as described above, the magnetic force exerted by the inclined surface 51b of the attraction position side magnet 51 on the component 3 located directly above the magnet 51 gradually decreases from the magnetic force G2 toward the traveling direction of the carrier tape 18, so that the component by the attraction nozzle 13a It is extremely unlikely that the suction of 3 is hindered by the magnetic force received from the magnet 51 on the suction position side.

上記構成の部品実装装置１では、基板搬送部１２、部品装着部１３、テープフィーダ１６等の作動制御は部品実装装置１が備える制御装置Ｃ（図１）が行う。制御装置Ｃに制御された基板搬送部１２は先ず、上流工程側から送られてきた基板２を搬入し、作業位置に位置決めする。そして、テープフィーダ１６が作動して部品供給位置１６Ｋに部品３を供給するとともに、ヘッド移動機構１３ｃが装着ヘッド１３ｂをテープフィーダ１６と基板２との間で往復移動させる。装着ヘッド１３ｂはテープフィーダ１６が部品供給位置１６Ｋに位置させる部品３を、部品供給開口３３Ｔを通して吸着ノズル１３ａによりピックアップし、そのピックアップした部品３を基板２に装着する。装着ヘッド１３ｂが基板２に装着すべき部品３を全て基板２に装着したら、基板搬送部１２は基板２を下流工程側に搬出する。 In the component mounting device 1 having the above configuration, the control device C (FIG. 1) included in the component mounting device 1 controls the operation of the board transport unit 12, the component mounting unit 13, the tape feeder 16, and the like. The substrate transport unit 12 controlled by the control device C first carries in the substrate 2 sent from the upstream process side and positions it at the working position. Then, the tape feeder 16 operates to supply the component 3 to the component supply position 16K, and the head moving mechanism 13c reciprocates the mounting head 13b between the tape feeder 16 and the substrate 2. The mounting head 13b picks up the component 3 located at the component supply position 16K by the tape feeder 16 through the component supply opening 33T by the suction nozzle 13a, and mounts the picked up component 3 on the substrate 2. When the mounting head 13b mounts all the components 3 to be mounted on the board 2 on the board 2, the board transport unit 12 carries the board 2 to the downstream process side.

このような基板２に対する部品３の装着過程において、各テープフィーダ１６は、部品実装装置１が備える吸着ノズル１３ａによる部品３の吸着位置である部品供給位置１６Ｋに部品３を供給するが、吸着位置側磁石５１及びスリット側磁石５２により、部品供給位置１６Ｋからの部品３の吸着は妨げられず、事前剥離の際、静電気でカバーテープ２２に付着した部品３がスリット３３Ｓから飛び出すこともない。 In the process of mounting the component 3 on the substrate 2, each tape feeder 16 supplies the component 3 to the component supply position 16K, which is the suction position of the component 3 by the suction nozzle 13a provided in the component mounting device 1, but the suction position The side magnet 51 and the slit side magnet 52 do not prevent the component 3 from being attracted from the component supply position 16K, and the component 3 attached to the cover tape 22 due to static electricity does not pop out from the slit 33S during pre-peeling.

以上説明したように、本実施の形態におけるテープフィーダ１６は、部品供給位置１６Ｋに位置した部品３を吸着位置側磁石５１によってテープ下受け部材５０の側に磁力で引き寄せ、スリット３３Ｓの下方に位置した部品３をスリット側磁石５２によってテープ下受け部材５０の側に磁力で引き寄せるようになっている。スリット側磁石５２は吸着位置側磁石５１とは独立して設けられて（別個の部材から成って）おり、吸着位置側磁石５１よりも大きい磁力を発揮させることができるので、部品供給位置１６Ｋにおいては、吸着ノズル１３ａにより部品３の吸着が妨げられない程度の磁力が発揮されるようにしつつ、スリット３３Ｓの位置においては、カバーテープ２２の剥離に伴う静電気によるキャリヤテープ１８からの部品３の飛び出しを確実に防止できる程度の磁力を発揮させることができる。このため部品供給位置１６Ｋからの部品３の吸着を妨げることなく、事前剥離の際、静電気でカバーテープ２２に付着した部品３がスリット３３Ｓから飛び出してしまう事態を防止でき、安定した部品供給動作を実現することができる。 As described above, the tape feeder 16 in the present embodiment magnetically attracts the component 3 located at the component supply position 16K to the side of the tape underlay member 50 by the attraction position side magnet 51, and is positioned below the slit 33S. The part 3 is magnetically attracted to the side of the tape underlay member 50 by the slit side magnet 52. The slit-side magnet 52 is provided independently of the attraction-position-side magnet 51 (consisting of a separate member), and can exert a larger magnetic force than the attraction-position-side magnet 51. Therefore, at the component supply position 16K. Is such that the suction nozzle 13a exerts a magnetic force that does not hinder the suction of the component 3, and at the position of the slit 33S, the component 3 pops out from the carrier tape 18 due to static electricity due to the peeling of the cover tape 22. It is possible to exert a magnetic force that can surely prevent. Therefore, it is possible to prevent the component 3 adhering to the cover tape 22 from popping out from the slit 33S due to static electricity at the time of pre-peeling without hindering the adsorption of the component 3 from the component supply position 16K, and a stable component supply operation can be performed. It can be realized.

事前剥離の際、静電気でカバーテープに付着した部品がスリットから飛び出してしまう事態を防止でき、安定した部品供給動作を実現することができるテープフィーダを提供する。 Provided is a tape feeder capable of preventing a situation in which a part attached to a cover tape due to static electricity pops out from a slit at the time of pre-peeling and realizing a stable part supply operation.
