Description
本発明は、部品実装機の実装ヘッドに装着された複数のフィルターユニットを一括して交換するフィルターユニット交換装置に関する発明である。
The present invention is an invention relating to a filter unit exchanging apparatus that collectively replaces a plurality of filter units mounted on a mounting head of a component mounting machine.
特許文献１（特開２０１１－２９５２７号公報）に記載された部品実装機は、複数の吸着ノズルを保持する実装ヘッドの上面外周部に沿って複数のフィルター装着孔が複数の吸着ノズルのエアー流路に連通するように形成され、複数のフィルター装着孔に複数のフィルターユニットを装着して、各エアー流路から各吸着ノズルに供給するエアーを各フィルターユニットで濾過するようにしている。
In the component mounting machine described in Patent Document 1 (Japanese Patent Laid-Open No. 2011-29527), a plurality of filter mounting holes are provided along the outer periphery of the upper surface of the mounting head that holds a plurality of suction nozzles. A plurality of filter units are mounted in a plurality of filter mounting holes so as to communicate with the passage, and the air supplied from the air flow paths to the suction nozzles is filtered by the filter units.
ところで、実装ヘッドの各フィルター装着孔に装着した各フィルターユニットは、使用時間が長くなるに従って目詰りしていくため、定期的に交換する必要がある。フィルターユニットの交換時には、フィルターユニットを１個ずつ実装ヘッドのフィルター装着孔から取り外して新しいフィルターユニットをフィルター装着孔に装着するという作業を繰り返す必要があるが、近年の部品の小型化に伴って実装ヘッドが小型化してフィルターユニットも小型化しているため、作業者がフィルターユニットを指先でつまんで交換することが困難になっている。このため、作業者がフィルターユニットを１個ずつピンセットでつまんで交換するという手間のかかる作業を行わなければならず、実装ヘッドの複数のフィルター装着孔に装着された複数のフィルターユニットを交換する作業が甚だ面倒であった。
By the way, each filter unit mounted in each filter mounting hole of the mounting head clogs as the usage time becomes longer, so it is necessary to replace it periodically. When replacing the filter unit, it is necessary to repeat the work of removing the filter unit one by one from the filter mounting hole of the mounting head and mounting a new filter unit to the filter mounting hole. Since the head is miniaturized and the filter unit is also miniaturized, it is difficult for an operator to pinch and replace the filter unit with a fingertip. For this reason, an operator has to perform the laborious work of picking and replacing the filter units one by one with tweezers, and replacing the plurality of filter units mounted in the plurality of filter mounting holes of the mounting head. However, it was troublesome.
そこで、本発明が解決しようとする課題は、実装ヘッドの複数のフィルター装着孔に装着された複数のフィルターユニットを交換する作業を簡単に行うことができるフィルターユニット交換装置を提供することである。
Therefore, a problem to be solved by the present invention is to provide a filter unit exchanging device that can easily perform an operation of exchanging a plurality of filter units mounted in a plurality of filter mounting holes of a mounting head.
上記課題を解決するために、本発明は、部品実装機の実装ヘッドに装着された複数のフィルターユニットを一括して交換するフィルターユニット交換装置であって、前記実装ヘッドには、前記複数の吸着ノズルにそれぞれエアーを供給する複数のエアー流路が設けられていると共に、前記実装ヘッドにその外側から前記複数のエアー流路に連通する複数のフィルター装着孔が設けられ、前記複数のフィルターユニットは、前記実装ヘッドの外側から前記複数のフィルター装着孔に着脱可能に装着されて前記複数のエアー流路を流れるエアーを濾過するものであり、前記複数のフィルターユニットを連結して一体化する変形可能な連結部材を備えていることを特徴とするものである。
In order to solve the above-described problems, the present invention provides a filter unit exchanging device that collectively replaces a plurality of filter units mounted on a mounting head of a component mounting machine, wherein the mounting head includes the plurality of suction units. A plurality of air flow paths for supplying air to the nozzles are provided, and a plurality of filter mounting holes that communicate with the plurality of air flow paths from the outside of the mounting head are provided in the mounting head. The filter unit is detachably mounted in the plurality of filter mounting holes from the outside of the mounting head and filters the air flowing through the plurality of air flow paths, and is deformable by connecting and integrating the plurality of filter units. It is characterized by comprising a simple connecting member.
この構成では、実装ヘッドの複数のフィルター装着孔に装着する複数のフィルターユニットを、変形可能な連結部材で連結して一体化しているため、フィルターユニットの交換時に作業者が実装ヘッドの複数のフィルター装着孔に装着されている複数のフィルターユニットを取り外す際に、連結部材で連結された複数のフィルターユニットを芋づる式に簡単に取り外すことができる。しかも、新たな複数のフィルターユニットを実装ヘッドの複数のフィルター装着孔に装着する際に、複数のフィルターユニットの表裏を一括して簡単に識別でき、複数のフィルターユニットの交換作業を簡単に行うことができる。
In this configuration, since the plurality of filter units to be mounted in the plurality of filter mounting holes of the mounting head are connected and integrated by a deformable connecting member, the operator can replace the plurality of filters of the mounting head when replacing the filter unit. When removing the plurality of filter units mounted in the mounting hole, the plurality of filter units connected by the connecting member can be easily removed in a manner that grips them. Moreover, when installing multiple new filter units in multiple filter mounting holes in the mounting head, the front and back of the multiple filter units can be easily identified together, and the replacement of multiple filter units can be performed easily. Can do.
本発明は、連結部材に、複数のフィルターユニットを複数のフィルター装着孔の間隔と同じ間隔で保持させるようにすると良い。このようにすれば、複数のフィルターユニットを実装ヘッドの複数のフィルター装着孔に装着する際に、最初に１つのフィルターユニットを最初のフィルター装着孔に装着すれば、順番に、次のフィルター装着孔に対して次のフィルターユニットを簡単に位置合わせして装着していくことができ、複数のフィルターユニットの装着作業を簡単に行うことができる。
In the present invention, the connecting member may be configured to hold the plurality of filter units at the same interval as the interval between the plurality of filter mounting holes. In this way, when a plurality of filter units are mounted in the plurality of filter mounting holes of the mounting head, if one filter unit is first mounted in the first filter mounting hole, the next filter mounting hole is sequentially installed. On the other hand, the next filter unit can be easily aligned and mounted, and mounting of a plurality of filter units can be easily performed.
また、連結部材に、複数のフィルターユニットを着脱可能に係合保持させるようにしても良い。このようにすれば、連結部材に係合保持された複数のフィルターユニットのうちの一部のフィルターユニットのみが目詰りしている場合には、その目詰りしたフィルターユニットのみを連結部材から取り外して、新たなフィルターユニットを連結部材に係合保持させるという使用方法が可能となり、複数のフィルターユニットを全て目詰りするまで使用することができる。
Also, a plurality of filter units may be detachably engaged with the connecting member. In this way, when only some of the filter units engaged and held by the connecting member are clogged, remove only the clogged filter unit from the connecting member. The use method of engaging and holding a new filter unit with the connecting member becomes possible, and the filter unit can be used until all the filter units are clogged.
本発明は、複数のフィルターユニットを装着する実装ヘッドであれば、どの様なタイプの実装ヘッドであっても適用可能であり、例えば、複数の吸着ノズルを円周方向に配列した回転型の実装ヘッドである場合は、その実装ヘッドの外周面の同一円周線上に複数のフィルター装着孔を等間隔で形成するようにすれば良い。このようにすれば、実装ヘッドの複数のフィルター装着孔のうちのいずれのフィルター装着孔に、最初にフィルターユニットを装着しても、連結部材に保持された複数のフィルターユニットを実装ヘッドの複数のフィルター装着孔に全て装着することができる。
The present invention can be applied to any type of mounting head as long as it mounts a plurality of filter units. For example, a rotary mounting in which a plurality of suction nozzles are arranged in the circumferential direction. In the case of a head, a plurality of filter mounting holes may be formed at equal intervals on the same circumferential line on the outer peripheral surface of the mounting head. According to this configuration, even if the filter unit is first mounted in any one of the plurality of filter mounting holes of the mounting head, the plurality of filter units held by the connecting member are connected to the plurality of mounting heads. All can be installed in the filter mounting hole.

本実施例の実装ヘッド１１は、複数の吸着ノズル１２を円周方向に配列した回転型（リボルバー型又はロータリー型とも呼ばれる）の実装ヘッドである。図示はしないが、部品実装機には、実装ヘッド１１を基板の搬送方向（以下この方向を「Ｘ軸方向」と定義する）に移動させるＸ軸スライド機構と、このＸ軸スライド機構を実装ヘッド１１と共にＹ軸方向（基板の搬送方向と直交する方向）に移動させるＹ軸スライド機構と、部品吸着動作時や実装動作時に実装ヘッド１１の吸着ノズル１２を昇降させるノズル昇降機構１３等が設けられている。
The mounting head 11 of this embodiment is a rotary type (also called a revolver type or rotary type) mounting head in which a plurality of suction nozzles 12 are arranged in the circumferential direction. Although not shown, the component mounter includes an X-axis slide mechanism that moves the mounting head 11 in the board transport direction (hereinafter, this direction is defined as “X-axis direction”), and the X-axis slide mechanism as a mounting head. 11 is provided with a Y-axis slide mechanism that moves in the Y-axis direction (a direction orthogonal to the board conveyance direction), a nozzle lifting mechanism 13 that lifts and lowers the suction nozzle 12 of the mounting head 11 during component suction operation and mounting operation, and the like. ing.
図１に示すように、実装ヘッド１１は、Ｘ軸スライド機構のＸ軸スライド１４に固定された支持ブラケット１５に回転可能に組み付けられ、ヘッド回転用のモータ１６によって該実装ヘッド１１の中心軸の回りを吸着ノズル１２の配列ピッチ角度ずつ間欠的に回転する（ピッチ駆動する）ように構成されている。この実装ヘッド１１には、吸着ノズル１２を保持する複数本のノズルホルダ１７が上下方向（Ｚ方向）に昇降可能に組み付けられ、部品吸着・実装動作時には、所定の部品吸着・実装ステーションに位置する１本のノズルホルダ１７（吸着ノズル１２）がノズル昇降モータ１８を駆動源とするノズル昇降機構１３によって昇降されるように構成されている。
As shown in FIG. 1, the mounting head 11 is rotatably assembled to a support bracket 15 fixed to an X-axis slide 14 of an X-axis slide mechanism, and the center axis of the mounting head 11 is rotated by a head rotation motor 16. The rotation is intermittently rotated (pitch driven) by the arrangement pitch angle of the suction nozzles 12. A plurality of nozzle holders 17 that hold the suction nozzle 12 are assembled to the mounting head 11 so as to be movable up and down (Z direction), and are located at a predetermined component suction / mounting station during component suction / mounting operations. One nozzle holder 17 (suction nozzle 12) is configured to be moved up and down by a nozzle lifting mechanism 13 using a nozzle lifting motor 18 as a drive source.
図２に示すように、実装ヘッド１１の内部には、複数の吸着ノズル１２にそれぞれエアーを供給する複数のエアー流路２１が設けられ、該実装ヘッド１１の外周部には、その外側から複数のエアー流路２１に連通する複数のフィルター装着孔２２が該実装ヘッド１１の外周面の同一円周線上に等間隔（等ピッチ）で形成されている。各フィルター装着孔２２には、それぞれ、実装ヘッド１１の外側からフィルターユニット２３が着脱可能に押し込まれて装着されている。
As shown in FIG. 2, a plurality of air flow paths 21 that supply air to the plurality of suction nozzles 12 are provided inside the mounting head 11, and a plurality of air flow paths 21 are provided on the outer periphery of the mounting head 11 from the outside. A plurality of filter mounting holes 22 communicating with the air flow path 21 are formed at equal intervals (equal pitch) on the same circumferential line on the outer peripheral surface of the mounting head 11. A filter unit 23 is detachably inserted into each filter mounting hole 22 from the outside of the mounting head 11.
図３に示すように、各フィルターユニット２３は、フィルターケース２４内に円筒状のフィルター部材２５を装着した構成であり、該フィルターケース２４には、実装ヘッド１１の各エアー流路２１に連通する通気孔２６が形成され、該フィルターケース２４の外周部には、フィルター装着孔２２の内周面との間の隙間をシールするＯリング等のシール部材２７，２８が装着されている。各吸着ノズル１２に吸着した部品を解放する場合は、実装ヘッド１１の各エアー流路２１に正圧のエアーを供給し、該エアーを各フィルターユニット２３の通気孔２６からフィルター部材２５を通過させ、その過程で、該エアーを濾過する。これにより、エアーに含まれた塵埃が取り除かれ、該エアーが各ノズルホルダ１７内のエアー流路２９（図２参照）を流れて各吸着ノズル１２に供給される。各吸着ノズル１２に部品を吸着する場合は、エアーの流れが上記の方向とは逆方向となる。
As shown in FIG. 3, each filter unit 23 has a configuration in which a cylindrical filter member 25 is mounted in a filter case 24, and the filter case 24 communicates with each air flow path 21 of the mounting head 11. A vent hole 26 is formed, and seal members 27 and 28 such as O-rings that seal a gap between the filter case 24 and the inner peripheral surface of the filter mounting hole 22 are mounted on the outer periphery of the filter case 24. When releasing the component adsorbed by each suction nozzle 12, positive pressure air is supplied to each air flow path 21 of the mounting head 11, and the air is passed through the filter member 25 from the vent hole 26 of each filter unit 23. In the process, the air is filtered. Thereby, the dust contained in the air is removed, and the air flows through the air flow path 29 (see FIG. 2) in each nozzle holder 17 and is supplied to each suction nozzle 12.

At the end of each filter unit 23 on the connection side, an inversely tapered engagement convex portion 34 that can be elastically engaged with each engagement hole 33 of the connection member 31 is formed. When engaging the engaging projections 34 of the filter unit 23 with the engaging holes 33 of the connecting member 31, the engaging members 33 are elastically deformed to increase the opening diameter of the engaging holes 33. The engaging convex part 34 is engaged with.

次に、上記構成のフィルターユニット連結体３２の使用方法を説明する。
本実施例では、連結部材３１に複数のフィルターユニット２３を着脱可能に係合保持するようにしているため、部品実装機の運転中は、実装ヘッド１１に装着した複数のフィルターユニット２３から連結部材３１を取り外して、フィルターユニット２３の交換時のみに連結部材３１を使用するようにしても良いし、勿論、複数のフィルターユニット２３に連結部材３１を取り付けた状態のままで部品実装機を運転するようにしても良い。以下、フィルターユニット２３の交換時のみに連結部材３１を使用する場合について説明する。 Next, the usage method of the filterunit coupling body 32 of the said structure is demonstrated.
In the present embodiment, since the plurality offilter units 23 are detachably engaged with and held by the connecting member 31, during operation of the component mounting machine, the connecting members are connected to the plurality of filter units 23 attached to the mounting head 11. 31 may be removed, and the connecting member 31 may be used only when the filter unit 23 is replaced. Of course, the component mounting machine is operated with the connecting members 31 attached to the plurality of filter units 23. You may do it. Hereinafter, a case where the connecting member 31 is used only when the filter unit 23 is replaced will be described.
本実施例では、連結部材３１に複数のフィルターユニット２３を着脱可能に係合保持するようにしているため、部品実装機の運転中は、実装ヘッド１１に装着した複数のフィルターユニット２３から連結部材３１を取り外して、フィルターユニット２３の交換時のみに連結部材３１を使用するようにしても良いし、勿論、複数のフィルターユニット２３に連結部材３１を取り付けた状態のままで部品実装機を運転するようにしても良い。以下、フィルターユニット２３の交換時のみに連結部材３１を使用する場合について説明する。 Next, the usage method of the filter
In the present embodiment, since the plurality of
図２に示すように、実装ヘッド１１の複数のフィルター装着孔２２に装着された複数のフィルターユニット２３を交換する場合は、まず、作業者が実装ヘッド１１に装着した複数のフィルターユニット２３に連結部材３１を取り付ける。この後、複数のフィルターユニット２３が保持された連結部材３１の片方の端を指先で摘んで、該連結部材３１を実装ヘッド１１の外周部から引き剥がすようにすれば、該連結部材３１に保持された複数のフィルターユニット２３が１個ずつ順番にフィルター装着孔２２から引き出される。これにより、連結部材３１で連結された複数のフィルターユニット２３を芋づる式に簡単に取り外すことができる。
As shown in FIG. 2, when replacing the plurality of filter units 23 mounted in the plurality of filter mounting holes 22 of the mounting head 11, first, the operator connects to the plurality of filter units 23 mounted on the mounting head 11. The member 31 is attached. Thereafter, if one end of the connecting member 31 holding the plurality of filter units 23 is grasped with a fingertip and the connecting member 31 is peeled off from the outer peripheral portion of the mounting head 11, the connecting member 31 is held by the connecting member 31. A plurality of the filter units 23 are pulled out from the filter mounting hole 22 one by one in order. As a result, the plurality of filter units 23 connected by the connecting member 31 can be easily removed according to a formula.
この後、新たな複数のフィルターユニット２３を実装ヘッド１１の複数のフィルター装着孔２２に装着する場合は、まず、作業者が複数のフィルターユニット２３を連結部材３１に取り付ける。この状態では、複数のフィルターユニット２３が連結部材３１で連結されて一体化されているため、複数のフィルターユニット２３の表裏を一括して簡単に識別できる。しかも、連結部材３１に保持された複数のフィルターユニット２３の間隔が複数のフィルター装着孔２２の間隔と同じ間隔となっているため、最初に１つのフィルターユニット２３を最初のフィルター装着孔２２に装着すれば、順番に、次のフィルター装着孔２２に対して次のフィルターユニット２３を簡単に位置合わせして装着していくことができる。更に、本実施例では、実装ヘッド１１の外周面の同一円周線上に複数のフィルター装着孔２２が等間隔で形成されているため、実装ヘッド１１の複数のフィルター装着孔２２のうちのいずれのフィルター装着孔２２に、最初にフィルターユニット２３を装着しても、連結部材３１に保持された複数のフィルターユニット２３を実装ヘッド１１の複数のフィルター装着孔２２に全て装着することができる。これにより、複数のフィルターユニット２３の装着作業を極めて簡単に行うことができる。
Thereafter, when a plurality of new filter units 23 are mounted in the plurality of filter mounting holes 22 of the mounting head 11, the operator first attaches the plurality of filter units 23 to the connecting member 31. In this state, since the plurality of filter units 23 are connected by the connecting member 31 and integrated, the front and back of the plurality of filter units 23 can be easily identified collectively. Moreover, since the interval between the plurality of filter units 23 held by the connecting member 31 is the same as the interval between the plurality of filter mounting holes 22, one filter unit 23 is first mounted in the first filter mounting hole 22. Then, in order, the next filter unit 23 can be easily positioned and attached to the next filter attachment hole 22. Furthermore, in this embodiment, since the plurality of filter mounting holes 22 are formed at equal intervals on the same circumferential line of the outer peripheral surface of the mounting head 11, any of the plurality of filter mounting holes 22 of the mounting head 11 is formed. Even if the filter unit 23 is first mounted in the filter mounting hole 22, the plurality of filter units 23 held by the connecting member 31 can all be mounted in the plurality of filter mounting holes 22 of the mounting head 11. Thereby, the mounting operation of the plurality of filter units 23 can be performed very easily.
しかも、本実施例では、連結部材３１に、複数のフィルターユニット２３を着脱可能に係合保持させるようにしたので、連結部材３１に係合保持された複数のフィルターユニット２３のうちの一部のフィルターユニット２３のみが目詰りしている場合には、その目詰りしたフィルターユニット２３のみを連結部材３１から取り外して、新たなフィルターユニット２３を連結部材３１に係合保持させるという使用方法が可能となり、複数のフィルターユニット２３を全て目詰りするまで使用することができ、経済的である。
In addition, in the present embodiment, since the plurality of filter units 23 are detachably engaged with the connecting member 31, some of the plurality of filter units 23 engaged with the connecting member 31 are retained. When only the filter unit 23 is clogged, it is possible to use such a method that only the clogged filter unit 23 is removed from the connecting member 31 and the new filter unit 23 is engaged with the connecting member 31. The plurality of filter units 23 can be used until they are all clogged, which is economical.
尚、本実施例では、回転型の実装ヘッド１１で説明したが、本発明は、複数のフィルターユニットを装着する実装ヘッドであれば、例えば、複数のフィルターユニットを一直線上に配列した実装ヘッド等、どの様なタイプの実装ヘッドであっても適用可能である。
In this embodiment, the rotary mounting head 11 has been described. However, if the present invention is a mounting head on which a plurality of filter units are mounted, for example, a mounting head in which a plurality of filter units are arranged in a straight line, etc. Any type of mounting head is applicable.
その他、本発明は、フィルターユニットの構造を変更したり、連結部材に対するフィルターユニットの保持構造を変更しても良い等、要旨を逸脱しない範囲内で、種々変更して実施できることは言うまでもない。
Besides, it goes without saying that the present invention can be implemented with various modifications within a range not departing from the gist, such as changing the structure of the filter unit or changing the holding structure of the filter unit with respect to the connecting member.
