Description

本発明は、ピッチ変更装置に関し、特に電子部品を基板に実装する部品実装装置に関する。 The present invention relates to a pitch changing device, and more particularly to a component mounting device for mounting electronic components on a substrate.

従来から、基板に電子部品（以下、単に「部品」という）を実装する装置として部品実装装置がある。部品実装装置においては、実装ヘッドが部品トレイ及びテープフィーダから部品を取り出して基板に移送搭載する。 Conventionally, there is a component mounting apparatus as an apparatus for mounting an electronic component (hereinafter simply referred to as “component”) on a substrate. In the component mounting apparatus, a mounting head takes out components from a component tray and a tape feeder, and transfers and mounts them on a substrate.

このような部品実装装置に対する作業効率向上、つまり実装時間の短縮の要請から、部品実装装置の実装ヘッドとして、複数の吸着ノズルを備えるものが用いられている。これにより、実装ヘッドが部品供給装置と基板との間を往復する１タスクにおいて、複数の部品を取り出して実装することが可能になる。 In order to improve the working efficiency of such a component mounting apparatus, that is, to reduce the mounting time, a mounting head of a component mounting apparatus that includes a plurality of suction nozzles is used. Thereby, it is possible to take out and mount a plurality of components in one task in which the mounting head reciprocates between the component supply device and the substrate.

ところで、複数の吸着ノズルを用いて部品トレイ若しくはテープフィーダから同時に複数の部品を取り出そうとした場合、吸着ノズルのピッチを変更し、部品トレイにおける部品の間隔若しくはテープフィーダの並び間隔に対応させる必要がある。吸着ノズルのピッチを変更する技術としては、例えば特許文献１に記載の部品実装装置がある。この部品実装装置では、吸着ノズル毎に個別の駆動部を設け、これにより吸着ノズルを移動させて吸着ノズルのピッチを変更している。 By the way, when it is going to take out a plurality of parts simultaneously from a component tray or a tape feeder using a plurality of suction nozzles, it is necessary to change the pitch of the suction nozzles to correspond to the interval between parts in the component tray or the arrangement interval of the tape feeders. is there. As a technique for changing the pitch of the suction nozzle, for example, there is a component mounting apparatus described in Patent Document 1. In this component mounting apparatus, an individual drive unit is provided for each suction nozzle, and thereby the suction nozzle is moved to change the pitch of the suction nozzle.

このとき、吸着ノズルのピッチを変更する技術ではないが、並んで配置された複数の部材のピッチを変更する技術として、例えば特許文献２に記載のトレイ供給装置がある。このトレイ供給装置では、並んで配置された複数の部材としての複数のトレイのピッチを図７に示されるような機構を用いて変更している。すなわち、中央から上下逆向きのネジが形成されたボールネジ２１ａ、２１ｂを設け、一方のボールネジ２１ａの中央（ネジの向きが変わる位置）Ａにトレイ４ａを固定し、更に中央Ａに対して対称な部分にトレイ４ｂ、４ｃを固定し、他方のボールネジ２１ｂの中央（ネジの向きが変わる位置）Ｂに対して対称な部分にトレイ４ｄ、４ｅを固定する機構を用いてトレイのピッチを変更している。この機構においては、２つのボールネジ２１ａ、２１ｂをモータ２４により回転させることで、複数のトレイのピッチが等間隔を保ちながら変更される。
特開２００２−１７６２９１号公報特開平９−２１９４３６号公報 At this time, although not a technique for changing the pitch of the suction nozzles, there is a tray supply device described in Patent Document 2, for example, as a technique for changing the pitch of a plurality of members arranged side by side. In this tray supply device, the pitch of a plurality of trays as a plurality of members arranged side by side is changed using a mechanism as shown in FIG. In other words, ball screws 21a and 21b formed with screws upside down from the center are provided, and the tray 4a is fixed to the center (position where the direction of the screw changes) A of one ball screw 21a, and further symmetrical with respect to the center A. Tray 4b, 4c is fixed to the part, and the pitch of the tray is changed using a mechanism for fixing the trays 4d, 4e to a part symmetrical to the center (position where the direction of the screw changes) B of the other ball screw 21b. Yes. In this mechanism, by rotating the two ball screws 21a and 21b by the motor 24, the pitch of the plurality of trays is changed while maintaining an equal interval.

しかしながら、特許文献１に記載の技術を用いて吸着ノズルのピッチを変更する場合には、吸着ノズル毎に個別の駆動部が設けられるため、実装ヘッドの機構が複雑になり、その重量が大きくなる。その結果、実装ヘッドの停止に際して実装ヘッドに大きな慣性力が働くこととなり、部品実装の位置精度が悪くなる。この問題は、実装ヘッドを高速で移動させると特に顕著になる。 However, when the pitch of the suction nozzle is changed using the technique described in Patent Document 1, a separate drive unit is provided for each suction nozzle, so that the mechanism of the mounting head becomes complicated and its weight increases. . As a result, a large inertial force acts on the mounting head when the mounting head is stopped, and the position accuracy of component mounting deteriorates. This problem becomes particularly noticeable when the mounting head is moved at high speed.

また、特許文献２に記載の技術を用いて吸着ノズルのピッチを変更する場合には、実装ヘッド毎に個別の駆動部を設ける必要が無くなる。しかし、この技術は、１つのボールネジにより２つの部材を移動させる構成を採るため、吸着ノズルの数に応じたボールネジが必要となる。その結果、実装ヘッドの機構が複雑になるので、その重量が大きくなり、またコストが増大する。この問題は、多数の吸着ノズルを有する実装ヘッドにおいて特に顕著になる。 Further, when the pitch of the suction nozzle is changed using the technique described in Patent Document 2, it is not necessary to provide a separate drive unit for each mounting head. However, since this technique adopts a configuration in which two members are moved by one ball screw, a ball screw corresponding to the number of suction nozzles is required. As a result, since the mechanism of the mounting head becomes complicated, its weight increases and the cost increases. This problem is particularly noticeable in a mounting head having a large number of suction nozzles.

そこで、本発明は、かかる問題点に鑑み、簡素な機構を有するピッチ変更装置を提供することを目的とする。 In view of the above problems, an object of the present invention is to provide a pitch changing device having a simple mechanism.

Therefore, since a plurality of pitches can be changed without complicating the mechanism of the device, a pitch changing device having a simple structure can be realized. That is, a low-cost pitch changing device can be realized.

モータ１２５は、回転部材１２７が並び方向に平行な軸を中心とした自転をするように、回転部材１２７を回転させる。 The motor 125 rotates the rotating member 127 so that the rotating member 127 rotates around an axis parallel to the arrangement direction.

このとき、第１保持部固定部材１２３ａ、第２保持部固定部材１２３ｂ、第３保持部固定部材１２３ｃ及び第４保持部固定部材１２３ｄは、第１支持部材１２２及びレール１２６により支持されているため、回転部材１２７の自転に際して回転部材１２７と共に回転しない。 At this time, the first holding member fixing member 123a, the second holding member fixing member 123b, the third holding member fixing member 123c, and the fourth holding member fixing member 123d are supported by the first support member 122 and the rail 126.

Thereby, the pitch in the arrangement direction among the 1st holding | maintenance part fixing member 123a, the 2nd holding | maintenance part fixing member 123b, the 3rd holding | maintenance part fixing member 123c, and the 4th holding | maintenance part fixing member 123d is changed simultaneously.

具体的には、図４（ｂ）に示されるように、回転部材１２７を時計回りに回転させた場合、第１ネジ１２４ａの他端が第１保持部固定部材１２３ａの内部に徐々に挿入されていく。これに伴って、第１ネジ１２４ａの一端と係合した第２保持部固定部材１２３ｂは、並び方向において第１保持部固定部材１２３ａ及び第２保持部固定部材１２３ｂ間の第１ピッチ（図４におけるｄ１）を狭める方向に第１ネジ１２４ａと一体となって第１ネジ１２４ａと共に移動する。その結果、第２保持部固定部材１２３ｂの移動量（第１ネジ１２４ａの第１保持部固定部材１２３ａの内部に入った量）だけ第１ピッチが狭められる。この第１ピッチの縮小と同時に、第２ネジ１２４ｂの他端も第２保持部固定部材１２３ｂの内部に徐々に挿入されていく。これに伴って、第２ネジ１２４ｂの一端と係合した第３保持部固定部材１２３ｃは、並び方向において第２保持部固定部材１２３ｂ及び第３保持部固定部材１２３ｃ間の第２ピッチ（図４におけるｄ２）を狭める方向に第２ネジ１２４ｂと一体となって第２ネジ１２４ｂと共に移動する。その結果、第３保持部固定部材１２３ｃの移動量（第２ネジ１２４ｂの第２保持部固定部材１２３ｂの内部に入った量）だけ第２ピッチが狭められる。また第１ピッチ及び第２ピッチの縮小と同時に、第３ネジ１２４ｃの他端も第３保持部固定部材１２３ｃの内部に徐々に挿入されていく。これに伴って、第３ネジ１２４ｃの一端と係合した第４保持部固定部材１２３ｄは、並び方向において第３保持部固定部材１２３ｃ及び第４保持部固定部材１２３ｄ間の第３ピッチ（図４におけるｄ３）を狭める方向に第３ネジ１２４ｃと一体となって第３ネジ１２４ｃと共に移動する。その結果、第４保持部固定部材１２３ｄの移動量（第３ネジ１２４ｃの第３保持部固定部材１２３ｃの内部に入った量）だけ第３ピッチが狭められる。 Specifically, as shown in FIG. 4B, when the rotating member 127 is rotated clockwise, the other end of the first screw 124a is gradually inserted into the first holding portion fixing member 123a. To go. Accordingly, the second holding portion fixing member 123b engaged with one end of the first screw 124a has a first pitch between the first holding portion fixing member 123a and the second holding portion fixing member 123b in the alignment direction (FIG. 4). In the direction of narrowing d1), the first screw 124a moves together with the first screw 124a. As a result, the first pitch is narrowed by the amount of movement of the second holding portion fixing member 123b (the amount of the first screw 124a entering the first holding portion fixing member 123a). Simultaneously with the reduction of the first pitch, the other end of the second screw 124b is gradually inserted into the second holding portion fixing member 123b. Accordingly, the third holding portion fixing member 123c engaged with one end of the second screw 124b has a second pitch between the second holding portion fixing member 123b and the third holding portion fixing member 123c in the alignment direction (FIG. 4). In the direction of narrowing d2), the second screw 124b moves together with the second screw 124b. As a result, the second pitch is narrowed by the amount of movement of the third holding portion fixing member 123c (the amount of the second screw 124b entering the second holding portion fixing member 123b). Simultaneously with the reduction of the first pitch and the second pitch, the other end of the third screw 124c is gradually inserted into the third holding portion fixing member 123c. Accordingly, the fourth holding portion fixing member 123d engaged with one end of the third screw 124c has a third pitch (FIG. 4) between the third holding portion fixing member 123c and the fourth holding portion fixing member 123d in the alignment direction. In the direction of narrowing d3), the third screw 124c moves together with the third screw 124c. As a result, the third pitch is narrowed by the amount of movement of the fourth holding portion fixing member 123d (the amount of the third screw 124c entering the third holding portion fixing member 123c).

一方、回転部材１２７を反時計回りに回転させた場合、第１ネジ１２４ａの他端が第１保持部固定部材１２３ａの内部から徐々に出ていく。これに伴って、第１ネジ１２４ａの一端と係合した第２保持部固定部材１２３ｂは、並び方向において第１保持部固定部材１２３ａ及び第２保持部固定部材１２３ｂ間の第１ピッチを拡げる方向に第１ネジ１２４ａと一体となって第１ネジ１２４ａと共に移動する。その結果、第２保持部固定部材１２３ｂの移動量（第１ネジ１２４ａの第１保持部固定部材１２３ａの内部から出てきた量）だけ第１ピッチが拡げられる。この第１ピッチの拡大と同時に、第２ネジ１２４ｂの他端も第２保持部固定部材１２３ｂの内部から徐々に出ていく。これに伴って、第２ネジ１２４ｂの一端と係合した第３保持部固定部材１２３ｃは、並び方向において第２保持部固定部材１２３ｂ及び第３保持部固定部材１２３ｃ間の第２ピッチを拡げる方向に第２ネジ１２４ｂと一体となって第２ネジ１２４ｂと共に移動する。その結果、第３保持部固定部材１２３ｃの移動量（第２ネジ１２４ｂの第２保持部固定部材１２３ｂの内部から出てきた量）だけ第２ピッチが拡げられる。また第１ピッチ及び第２ピッチの拡大と同時に、第３ネジ１２４ｃの他端も第３保持部固定部材１２３ｃの内部から徐々に出ていく。これに伴って、第３ネジ１２４ｃの一端と係合した第４保持部固定部材１２３ｄは、並び方向において第３保持部固定部材１２３ｃ及び第４保持部固定部材１２３ｄ間の第３ピッチを拡げる方向に第３ネジ１２４ｃと一体となって第３ネジ１２４ｃと共に移動する。その結果、第４保持部固定部材１２３ｄの移動量（第３ネジ１２４ｃの第３保持部固定部材１２３ｃの内部から出てきた量）だけ第３ピッチが拡げられる。 On the other hand, when the rotating member 127 is rotated counterclockwise, the other end of the first screw 124a gradually protrudes from the inside of the first holding portion fixing member 123a. Accordingly, the second holding portion fixing member 123b engaged with one end of the first screw 124a expands the first pitch between the first holding portion fixing member 123a and the second holding portion fixing member 123b in the alignment direction. The first screw 124a moves together with the first screw 124a. As a result, the first pitch is increased by the amount of movement of the second holding portion fixing member 123b (the amount of the first screw 124a coming out of the first holding portion fixing member 123a). Simultaneously with the expansion of the first pitch, the other end of the second screw 124b gradually comes out of the second holding portion fixing member 123b. Accordingly, the third holding portion fixing member 123c engaged with one end of the second screw 124b expands the second pitch between the second holding portion fixing member 123b and the third holding portion fixing member 123c in the alignment direction. The second screw 124b moves together with the second screw 124b. As a result, the second pitch is increased by the amount of movement of the third holding portion fixing member 123c (the amount of the second screw 124b coming out of the second holding portion fixing member 123b). Simultaneously with the expansion of the first pitch and the second pitch, the other end of the third screw 124c gradually emerges from the inside of the third holding portion fixing member 123c. Accordingly, the fourth holding portion fixing member 123d engaged with one end of the third screw 124c expands the third pitch between the third holding portion fixing member 123c and the fourth holding portion fixing member 123d in the arrangement direction. The third screw 124c moves together with the third screw 124c. As a result, the third pitch is expanded by the amount of movement of the fourth holding portion fixing member 123d (the amount of the third screw 124c coming out of the third holding portion fixing member 123c).

このとき、第１ネジ１２４ａ、第２ネジ１２４ｂ、第３ネジ１２４ｃ及び第４ネジ１２４ｄは、同時に同じ量だけ回転し、かつその外面には同じ形態の螺条が形成されている。従って、第１ピッチ、第２ピッチ及び第３ピッチの変更量は、等しくなる。 At this time, the first screw 124a, the second screw 124b, the third screw 124c, and the fourth screw 124d are simultaneously rotated by the same amount, and the same shape of thread is formed on the outer surface thereof. Therefore, the change amounts of the first pitch, the second pitch, and the third pitch are equal.

なお、上記ピッチ変更装置１２０において、第１ネジ１２４ａの一端が第１保持部固定部材１２３ａに回転可能な状態で係合し、第１ネジ１２４ａの他端が第２保持部固定部材１２３ｂに入る、あるいは出てもよい。同様に、第２ネジ１２４ｂの一端が第２保持部固定部材１２３ｂに回転可能な状態で係合し、第２ネジ１２４ｂの他端が第３保持部固定部材１２３ｃに入る、あるいは出てもよい。また、第３ネジ１２４ｃの一端が第３保持部固定部材１２３ｃに回転可能な状態で係合し、第３ネジ１２４ｃの他端が第４保持部固定部材１２３ｄに入る、あるいは出てもよい。 In the pitch changing device 120, one end of the first screw 124a engages with the first holding portion fixing member 123a in a rotatable state, and the other end of the first screw 124a enters the second holding portion fixing member 123b. Or you can leave. Similarly, one end of the second screw 124b may be engaged with the second holding portion fixing member 123b in a rotatable state, and the other end of the second screw 124b may enter or exit the third holding portion fixing member 123c. . Further, one end of the third screw 124c may be engaged with the third holding portion fixing member 123c in a rotatable state, and the other end of the third screw 124c may enter or exit the fourth holding portion fixing member 123d.

上記構成を有する部品実装装置１０１は、ピッチ変更装置１２０により第１ノズル保持部１０５ａ、第２ノズル保持部１０５ｂ、第３ノズル保持部１０５ｃ及び第４ノズル保持部１０５ｄのピッチ、つまり吸着ノズル１１２間のピッチをトレイ１０３における部品１０３ａの間隔に対応させて変更した後、ピッチが変更された実装ヘッド１０５を用いてトレイ１０３から部品１０３ａを同時に吸着して取り出し、取り出された部品１０３ａを基板１０２ａに実装する。 The component mounting apparatus 101 having the above configuration causes the pitch changing apparatus 120 to use the pitches of the first nozzle holding unit 105a, the second nozzle holding unit 105b, the third nozzle holding unit 105c, and the fourth nozzle holding unit 105d, that is, between the suction nozzles 112. The pitch is changed in accordance with the interval of the components 103a in the tray 103, and then the components 103a are simultaneously picked up and taken out from the tray 103 by using the mounting head 105 with the changed pitch, and the taken out components 103a are placed on the substrate 102a. Implement.

以上のように本実施の形態の部品実装装置によれば、複数のネジを１本の回転部材１２７で支持し、その回転部材１２７を回転させて第１ネジ１２４ａ、第２ネジ１２４ｂ、第３ネジ１２４ｃ及び第４ネジ１２４ｄを同時に同量だけ回転させることで、ノズル保持部間のピッチを変更する。よって、実装ヘッドの機構を複雑化することなく吸着ノズルのピッチを変更することができるので、吸着ノズルのピッチを変更することが可能な簡素な構造の部品実装装置を実現することができる。すなわち、吸着ノズルのピッチを簡易に変更でき、かつ部品実装の位置精度が高い低コストの部品実装装置を実現することができる。 As described above, according to the component mounting apparatus of the present embodiment, a plurality of screws are supported by one rotating member 127, and the rotating member 127 is rotated to rotate the first screw 124a, the second screw 124b, and the third screw. By rotating the screw 124c and the fourth screw 124d simultaneously by the same amount, the pitch between the nozzle holding portions is changed. Therefore, since the pitch of the suction nozzle can be changed without complicating the mechanism of the mounting head, a component mounting apparatus having a simple structure that can change the pitch of the suction nozzle can be realized. That is, it is possible to realize a low-cost component mounting apparatus that can easily change the pitch of the suction nozzle and has high component mounting positional accuracy.

また、本実施の形態の部品実装装置によれば、第１ネジ１２４ａの並び方向における幅が第１保持部固定部材１２３ａの並び方向における幅よりも小さい。よって、第１ネジ１２４ａを第１保持部固定部材１２３ａとの螺合により貫通孔１３２ａに完全に挿入させることができるので、吸着ノズル１１２間のピッチを極めて小さくすることができる。その結果、高い自由度をもって吸着ノズル間のピッチを設定することが可能な部品実装装置を実現することができる。 Further, according to the component mounting apparatus of the present embodiment, the width in the alignment direction of the first screws 124a is smaller than the width in the alignment direction of the first holding portion fixing members 123a. Accordingly, since the first screw 124a can be completely inserted into the through hole 132a by screwing with the first holding portion fixing member 123a, the pitch between the suction nozzles 112 can be extremely reduced. As a result, a component mounting apparatus that can set the pitch between the suction nozzles with a high degree of freedom can be realized.

また、本実施の形態のピッチ変更装置によれば、吸着ノズル（保持部固定部材）が３個以上に増えても、保持部固定部材を並び方向にネジを介して連結するだけで、これに対応することができる。よって、吸着ノズル（保持部固定部材）が３個以上に増えても、１つのモータで吸着ノズルのピッチを変更することができるので、ピッチ変更装置の機構が複雑にならず、ピッチ変更装置の重量が大きくならない。その結果、ピッチ変更装置を備えたマルチノズルヘッドにおける、位置決め精度の低下を防止することができる。 Further, according to the pitch changing device of the present embodiment, even if the number of suction nozzles (holding portion fixing members) is increased to three or more, the holding portion fixing members are simply connected in the alignment direction via screws. Can respond. Therefore, even if the number of suction nozzles (holding member fixing members) is increased to three or more, the pitch of the suction nozzle can be changed by one motor, so the mechanism of the pitch change device is not complicated, and the pitch change device The weight does not increase. As a result, it is possible to prevent a decrease in positioning accuracy in the multi-nozzle head including the pitch changing device.

The warp correction unit 201 corrects the warp of the side edge portion of the flat panel 200b so that the flatness of the flat panel 200b is maintained at the time of joining. The warp correction unit 201 is provided with a plurality of bellows pads 201 a and air stop plugs 201 b, and the bellows pads 201 a are arranged in parallel with the backup stage 203.

By this adsorption, the flatness of the side edge of the flat panel 200b is maintained.

押圧部２０２は、固定台２１５と、固定台２１５上に順次並設された同一機能の第１押圧ヘッド駆動部２０５ａ、第２押圧ヘッド駆動部２０５ｂ、第３押圧ヘッド駆動部２０５ｃ及び第４押圧ヘッド駆動部２０５ｄと、上下軸駆動部２０４と、押圧ヘッド駆動部間の並び方向（図６におけるＸ方向）におけるピッチを変更する、第１の実施の形態のピッチ変更装置と同様の構成及び動作のピッチ変更装置１０２とから構成される。このとき、第１押圧ヘッド駆動部２０５ａ、第２押圧ヘッド駆動部２０５ｂ、第３押圧ヘッド駆動部２０５ｃ及び第４押圧ヘッド駆動部２０５ｄは、それぞれピッチ変更装置１０２の第１保持部固定部材１２３ａ、第２保持部固定部材１２３ｂ、第３保持部固定部材１２３ｃ及び第４保持部固定部材１２３ｄと一体化される。各押圧ヘッド駆動部は略同一機能の駆動部であるため、以下では第１押圧ヘッド駆動部２０５ａの構造についてのみ説明する。 The pressing unit 202 includes a fixed base 215, a first pressing head driving unit 205a, a second pressing head driving unit 205b, a third pressing head driving unit 205c, and a fourth pressing unit that are sequentially arranged on the fixing base 215 and have the same function. Configuration and operation similar to the pitch changing device of the first embodiment for changing the pitch in the alignment direction (X direction in FIG. 6) between the head driving unit 205d, the vertical axis driving unit 204, and the pressing head driving unit. The pitch change device 102 is configured. At this time, the first pressing head driving unit 205a, the second pressing head driving unit 205b, the third pressing head driving unit 205c, and the fourth pressing head driving unit 205d are respectively the first holding unit fixing member 123a of the pitch changing device 102, The second holding part fixing member 123b, the third holding part fixing member 123c, and the fourth holding part fixing member 123d are integrated. Since each pressing head driving unit is a driving unit having substantially the same function, only the structure of the first pressing head driving unit 205a will be described below.

なお、一体化された第１押圧ヘッド駆動部２０５ａ及び第１保持部固定部材１２３ａは本発明の第１押圧ユニットの一例であり、一体化された第２押圧ヘッド駆動部２０５ｂ及び第２保持部固定部材１２３ｂは本発明の第２押圧ユニットの一例であり、一体化された第３押圧ヘッド駆動部２０５及び第３保持部固定部材１２３ｃは本発明の第３押圧ユニットの一例である。 The integrated first pressing head driving unit 205a and the first holding unit fixing member 123a are an example of the first pressing unit of the present invention, and the integrated second pressing head driving unit 205b and the second holding unit. The fixing member 123b is an example of the second pressing unit of the present invention, and the integrated third pressing head driving unit 205 and the third holding unit fixing member 123c are an example of the third pressing unit of the present invention.

第１押圧ヘッド駆動部２０５ａは、押圧ヘッド２１０と、押圧ヘッド２１０を駆動するエアシリンダ２１１とから構成される。エアシリンダ２１１は、空気圧を駆動源とし、バックアップステージ２０３のフラットパネル２００ｂに向けて押圧ヘッド２１０を押圧する。押圧ヘッド２１０は、部品をバックアップステージ２０３上のフラットパネル２００ｂに向けて押圧し、かつ自身が押圧する部品を加熱する。 The first pressing head drive unit 205a includes a pressing head 210 and an air cylinder 211 that drives the pressing head 210. The air cylinder 211 presses the pressing head 210 toward the flat panel 200b of the backup stage 203 using air pressure as a driving source. The pressing head 210 presses the component toward the flat panel 200b on the backup stage 203 and heats the component that it presses.

上下軸駆動部２０４は、モータを駆動源とし、バックアップステージ２０３上のフラットパネル２００ｂに対して第１押圧ヘッド駆動部２０５ａ、第２押圧ヘッド駆動部２０５ｂ、第３押圧ヘッド駆動部２０５ｃ及び第４押圧ヘッド駆動部２０５ｄを上下動させる。すなわち、複数の押圧ヘッド２１０をフラットパネル２００ｂに対して同時に上下動させる。上下軸駆動部２０４は、サーボモータと、サーボモータを駆動するモータ駆動部と、押圧ヘッド駆動部に設けられたナットと係合し、サーボモータにより回転駆動されるボールねじ等の上下軸とから構成される。このような構成の上下軸駆動部２０４においては、サーボモータの作動により上下軸が回転し、これにより第１押圧ヘッド駆動部２０５ａ、第２押圧ヘッド駆動部２０５ｂ、第３押圧ヘッド駆動部２０５ｃ及び第４押圧ヘッド駆動部２０５ｄが同時に上下動する。 The vertical axis drive unit 204 uses a motor as a drive source, and the first press head drive unit 205a, the second press head drive unit 205b, the third press head drive unit 205c, and the fourth press with respect to the flat panel 200b on the backup stage 203. The pressing head drive unit 205d is moved up and down. That is, the plurality of pressing heads 210 are simultaneously moved up and down with respect to the flat panel 200b. The vertical axis driving unit 204 includes a servo motor, a motor driving unit that drives the servo motor, and a nut provided on the pressing head driving unit, and a vertical axis such as a ball screw that is rotationally driven by the servo motor. Composed. In the vertical axis driving unit 204 having such a configuration, the vertical axis is rotated by the operation of the servo motor, whereby the first pressing head driving unit 205a, the second pressing head driving unit 205b, the third pressing head driving unit 205c, and The fourth pressing head drive unit 205d moves up and down simultaneously.

上記構成を有する圧着装置２００は、ピッチ変更装置１２０により第１押圧ヘッド駆動部２０５ａ、第２押圧ヘッド駆動部２０５ｂ、第３押圧ヘッド駆動部２０５ｃ及び第４押圧ヘッド駆動部２０５ｄのピッチ、つまり押圧ヘッド２１０間のピッチをフラットパネル２００ｂに仮圧着されたフラットパネル２００ｂ上の部品の間隔に対応させて変更した後、ピッチが変更された押圧部２０２を用いて仮圧着された部品を押圧する。続いて、フラットパネル２００ｂの異なる辺に対して部品を押圧する場合には、その異なる辺における部品の間隔に対応させて押圧ヘッド２１０間のピッチを変更し、部品を押圧する。 The pressure bonding device 200 having the above configuration is configured so that the pitch changing device 120 uses the pitch of the first pressing head driving unit 205a, the second pressing head driving unit 205b, the third pressing head driving unit 205c, and the fourth pressing head driving unit 205d. After the pitch between the heads 210 is changed in accordance with the interval between the parts on the flat panel 200b that is temporarily press-bonded to the flat panel 200b, the parts that are temporarily press-bonded are pressed using the pressing portion 202 whose pitch is changed. Subsequently, when pressing components against different sides of the flat panel 200b, the pitch between the pressing heads 210 is changed in accordance with the interval between the components on the different sides, and the components are pressed.

以上のように本実施の形態の圧着装置によれば、複数のネジを１本の回転部材１２７で支持し、その回転部材１２７を回転させて第１ネジ１２４ａ、第２ネジ１２４ｂ、第３ネジ１２４ｃ及び第４ネジ１２４ｄを同時に同量だけ回転させることで、押圧ヘッド間のピッチを変更する。よって、押圧部の機構を複雑化することなく押圧ヘッドのピッチを変更することができるので、押圧ヘッドのピッチを変更することが可能な簡素な構造の圧着装置を実現することができる。すなわち、押圧ヘッドのピッチを簡易に変更でき、かつ部品圧着の位置精度が高い低コストの圧着装置を実現することができる。 As described above, according to the crimping apparatus of the present embodiment, a plurality of screws are supported by one rotating member 127, and the rotating member 127 is rotated to rotate the first screw 124a, the second screw 124b, and the third screw. The pitch between the pressing heads is changed by simultaneously rotating the 124c and the fourth screw 124d by the same amount. Therefore, since the pitch of the pressing head can be changed without complicating the mechanism of the pressing portion, it is possible to realize a crimping device having a simple structure capable of changing the pitch of the pressing head. That is, it is possible to realize a low-cost crimping apparatus that can easily change the pitch of the pressing head and has high positional accuracy for component crimping.

以上、本発明のピッチ変更装置について、実施の形態に基づいて説明したが、本発明は、この実施の形態の限定されるものではない。本発明の要旨を逸脱しない範囲内で当業者が思いつく各種変形を施したものも本発明の範囲内に含まれる。 As mentioned above, although the pitch change apparatus of this invention was demonstrated based on embodiment, this invention is not limited of this embodiment. The present invention includes various modifications made by those skilled in the art without departing from the scope of the present invention.

例えば、上記実施の形態において、第１支持部材１２２は、第１保持部固定部材１２３ａ、第２保持部固定部材１２３ｂ、第３保持部固定部材１２３ｃ及び第４保持部固定部材１２３ｄの貫通孔内に配設されるとした。しかし、第１保持部固定部材１２３ａ、第２保持部固定部材１２３ｂ、第３保持部固定部材１２３ｃ及び第４保持部固定部材１２３ｄが回転部材１２７の自転に際して回転部材１２７と共に回転しないようにする部材であればこれに限られず、第１支持部材はレール１２６と同様に第１保持部固定部材１２３ａ、第２保持部固定部材１２３ｂ、第３保持部固定部材１２３ｃ及び第４保持部固定部材１２３ｄをスライド可能に支持する部材であってもよい。また、レール１２６により、第１保持部固定部材１２３ａ、第２保持部固定部材１２３ｂ、第３保持部固定部材１２３ｃ及び第４保持部固定部材１２３ｄが回転部材１２７と共に回転しないようにできる目的は達成できるので、同様な機能を有する第１支持部材１２２を省略しても構わない。 For example, in the above embodiment, the first support member 122 is in the through hole of the first holding portion fixing member 123a, the second holding portion fixing member 123b, the third holding portion fixing member 123c, and the fourth holding portion fixing member 123d. It was supposed that it was arranged. However, the first holding portion fixing member 123a, the second holding portion fixing member 123b, the third holding portion fixing member 123c, and the fourth holding portion fixing member 123d are members that prevent the rotating member 127 from rotating together with the rotation of the rotating member 127. If it is, it will not be restricted to this, A 1st support member is the same as the rail 126, 1st holding | maintenance part fixing member 123a, 2nd holding | maintenance part fixing member 123b, 3rd holding | maintenance part fixing member 123c, and 4th holding | maintenance part fixing member 123d. The member may be slidably supported. Further, the rail 126 can achieve the purpose of preventing the first holding portion fixing member 123a, the second holding portion fixing member 123b, the third holding portion fixing member 123c, and the fourth holding portion fixing member 123d from rotating together with the rotating member 127. Therefore, the first support member 122 having a similar function may be omitted.

また、上記実施の形態において、第１ネジ１２４ａ、第２ネジ１２４ｂ、第３ネジ１２４ｃ及び第４ネジ１２４ｄの並び方向における幅は、それぞれ第１保持部固定部材１２３ａ、第２保持部固定部材１２３ｂ、第３保持部固定部材１２３ｃ及び第４保持部固定部材１２３ｄの並び方向における幅よりも小さいとしたが大きくてもよい。この場合には、吸着ノズル１１２又は押圧ヘッド２１０間のピッチを極めて大きくすることができる。 In the above embodiment, the widths of the first screw 124a, the second screw 124b, the third screw 124c, and the fourth screw 124d in the arrangement direction are respectively the first holding part fixing member 123a and the second holding part fixing member 123b. The third holding part fixing member 123c and the fourth holding part fixing member 123d may be larger than the width in the arrangement direction of the fourth holding part fixing member 123d. In this case, the pitch between the suction nozzle 112 or the pressing head 210 can be made extremely large.

また、上記実施の形態において、モータ１２５による回転駆動によりネジを回転させてピッチを変更するとしたが、第１保持部固定部材１２３ａ、第２保持部固定部材１２３ｂ、第３保持部固定部材１２３ｃ及び第４保持部固定部材１２３ｄの間にそれぞれ油圧駆動源を設け、この油圧駆動源の油圧駆動によりピッチを変更してもよい。 In the above embodiment, the pitch is changed by rotating the screw by the rotation drive by the motor 125, but the first holding part fixing member 123a, the second holding part fixing member 123b, the third holding part fixing member 123c, and A hydraulic drive source may be provided between the fourth holding portion fixing members 123d, and the pitch may be changed by hydraulic drive of the hydraulic drive source.

本発明は、ピッチ変更装置に利用でき、特に部品実装装置及び本圧着装置等に利用することができる。 The present invention can be used for a pitch changing device, and in particular, can be used for a component mounting device, a main pressure bonding device, and the like.
