Description
本発明はチップコイルなどの電子部品にワイヤを巻線するための巻線装置に関するものである。
The present invention relates to a winding device for winding a wire around an electronic component such as a chip coil.
従来、ボビンにワイヤを巻線する巻線装置として、特許文献1に記載のものがある。この巻線装置は、線材を供給する線材供給部と、線材が巻線される線材巻取部とからなり、線材供給部は線材の供給位置を規制するノズルを備え、線材巻取部は線材が巻付けられるボビンが装着されるスピンドルと、スピンドルを回転する回転機構と、スピンドルを3次元方向へ移動する移動機構とを備え、ボビンが搬送される搬送機構に対峙されてなる巻線装置である。線材供給部にノズルを3次元方向へ移動する移動機構を備えている。
Conventionally, there is a device described in Patent Document 1 as a winding device for winding a wire around a bobbin. The winding device includes a wire rod supply unit that supplies a wire rod and a wire rod winding unit around which the wire rod is wound. The wire rod supply unit includes a nozzle that regulates a supply position of the wire rod, and the wire rod winding unit is a wire rod. A winding device comprising a spindle on which a bobbin around which a bobbin is wound is mounted, a rotating mechanism for rotating the spindle, and a moving mechanism for moving the spindle in a three-dimensional direction, facing a conveying mechanism for conveying the bobbin. is there. The wire supply unit is provided with a moving mechanism for moving the nozzle in a three-dimensional direction.
特許文献1には、ポビンの端子に線材(ワイヤ)の始線部及び終線部を巻き付ける際に、ノズルを移動させることが記載されている。しかし、ノズルはワイヤをガイドしているだけであるから、ワイヤの端末部を端子に張力をもって巻付けることができず、巻付けを補助するための自動補助機構が別に必要になる。また、品種変更などで端子の位置が変更されたり、チップコイルのように端子が突出していない部品に端末処理を行う場合には、自動補助機構の変更も必要になり、大幅な設計変更を必要とする。さらに、回転駆動系が連結されたスピンドルを3次元方向に移動させるために、設備が大型かつ複雑になるという欠点がある。
Patent Document 1 describes that a nozzle is moved when winding a start line part and an end line part of a wire (wire) around a terminal of a pobin. However, since the nozzle only guides the wire, the terminal portion of the wire cannot be wound around the terminal with tension, and an automatic auxiliary mechanism for assisting winding is separately required. In addition, when the terminal position is changed due to change of product type, or when terminal processing is performed on parts that do not protrude such as chip coils, it is also necessary to change the automatic auxiliary mechanism, which requires significant design changes. And Furthermore, since the spindle connected to the rotational drive system is moved in a three-dimensional direction, there is a disadvantage that the equipment becomes large and complicated.
特許文献2には、コアをチャックするチャック爪の間に巻線を挿通すると共に、チャック爪に対してカッタ刃を移動させ、巻線の端末をチャック爪の軸心に挿通されたプッシャの軸端縁とカッタ刃とで切断するカッタ機構を配設した巻線機が開示されている。

A winding machine is disclosed in which a cutter mechanism for cutting with an edge and a cutter blade is provided.
特許文献2の場合には、カット刃を動かすための駆動装置を必要とし、この駆動装置を組み込むスペースが必要になる。そのため、インデックステーブル等を用いて巻線ステージとは別のステージでカット動作を行う必要があり、装置が複雑で大きくなるという問題がある。また、カット刃を動かすため、コアに対するカット位置のズレが発生する可能性がある。
In the case of Patent Document 2, a driving device for moving the cutting blade is required, and a space for incorporating this driving device is required. Therefore, it is necessary to perform a cutting operation on a stage different from the winding stage using an index table or the like, and there is a problem that the apparatus becomes complicated and large. Moreover, since the cutting blade is moved, there is a possibility that the cutting position is shifted from the core.
本発明の目的は、ワイヤを高精度で位置決めでき、品種変更等にフレキシブルに対応できる巻線装置を提供することにある。

Another object of the present invention is to provide a winding device that can be cut with a simple mechanism without causing a shift in the cut position of the start and end portions of the wire.
本発明に係る巻線装置は、コアにワイヤを巻線する巻線装置において、前記コアをチャックするスピンドルチャックと、前記スピンドルチャックを、一定位置で当該コアの軸線回りに回転駆動させる回転駆動機構と、前記ワイヤを案内しつつ供給するワイヤノズルと、前記ワイヤをチャック/開放するワイヤチャックと、前記ワイヤノズルを3軸方向に移動させる第1作動機構と、前記ワイヤチャックを3軸方向に移動させ、前記ワイヤノズルとワイヤチャックとの間に張り渡されたワイヤを前記コアの所定位置へと位置決めする第2作動機構と、を備えたことを特徴とする。
A winding device according to the present invention is a winding device that winds a wire around a core, and a spindle chuck that chucks the core, and a rotation drive mechanism that rotates the spindle chuck around the axis of the core at a fixed position. A wire nozzle for guiding and feeding the wire, a wire chuck for chucking / releasing the wire, a first operating mechanism for moving the wire nozzle in three axial directions, and moving the wire chuck in three axial directions And a second operating mechanism for positioning a wire stretched between the wire nozzle and the wire chuck to a predetermined position of the core.
本発明の巻線装置では、スピンドルチャックを一定位置で回転させ、ワイヤを供給するワイヤノズルを移動させることで、コアにワイヤを巻線する。スピンドルチャックはコアの軸線回りに一定位置で回転するだけであるから、スピンドルチャックの回転駆動機構を3軸方向に移動させる機構が不要となるため、回転駆動機構が簡素になり、高精度の回転と装置の小型化とを実現できる。ところで、ワイヤの始線部及び終線部を処理するに当たって、ワイヤをコアの所定位置(例えば一端部の電極部)に正確に位置決めする必要がある。本発明では、ワイヤノズルの他にワイヤチャックを用い、ワイヤノズルとワイヤチャックとをそれぞれ作動機構によって3軸方向に移動させる。ワイヤはワイヤノズルとワイヤチャックとの間に張り渡されるため、所定のテンションを保ちながらワイヤをコアの所定位置に正確に位置決めすることができる。また、コアの品種変更等があった場合でも、ワイヤノズルとワイヤチャックの組み合わせを変更する必要がなく、それらの作動機構の位置及び移動量を変更するだけで済むので、品種変更にフレキシブルに対応できる。
In the winding device of the present invention, the wire is wound around the core by rotating the spindle chuck at a fixed position and moving the wire nozzle for supplying the wire. Since the spindle chuck only rotates at a fixed position around the axis of the core, there is no need for a mechanism for moving the spindle chuck rotation drive mechanism in the three-axis direction, so the rotation drive mechanism is simplified and high-precision rotation is achieved. And downsizing of the apparatus can be realized. By the way, when processing the start line part and the end line part of the wire, it is necessary to accurately position the wire at a predetermined position of the core (for example, an electrode part at one end). In the present invention, a wire chuck is used in addition to the wire nozzle, and the wire nozzle and the wire chuck are respectively moved in three axial directions by the operation mechanism. Since the wire is stretched between the wire nozzle and the wire chuck, the wire can be accurately positioned at a predetermined position of the core while maintaining a predetermined tension. Even if there is a change in the core type, etc., it is not necessary to change the combination of the wire nozzle and wire chuck, and it is only necessary to change the position and amount of movement of those operating mechanisms. it can.
ワイヤの始線部を処理するに当たって、ワイヤチャックでワイヤの先端部をチャックし、コアの一端部にワイヤの始線部を位置決めするようにワイヤノズルとワイヤチャックとを移動させ、ワイヤをコアに巻線するに当たって、スピンドルチャックでコアを一定位置で回転させながら、ワイヤノズルをコアの軸線方向に往復移動させ、ワイヤの終線部を処理するに当たって、ワイヤチャックで巻線終了後のワイヤノズルとコアとの間のワイヤをチャックし、ワイヤチャックを移動させてワイヤの終線部をコアの一端部に位置決めするよう動作するのがよい。このように動作させることで、ワイヤに弛みを発生させずに、コアに対してワイヤの始線部及び終線部を正確に位置決めできると共に、コアの巻胴部に対してワイヤを正確に巻線できる。
In processing the wire start line, the wire chuck is used to chuck the wire tip, and the wire nozzle and wire chuck are moved so that the wire start line is positioned at one end of the core. When winding, the wire nozzle is reciprocated in the axial direction of the core while rotating the core at a fixed position with the spindle chuck, and the wire nozzle after winding is finished with the wire chuck when processing the end of the wire. The wire between the core and the core may be chucked, and the wire chuck may be moved to position the end of the wire at one end of the core. By operating in this way, the start and end portions of the wire can be accurately positioned with respect to the core without causing the wire to sag, and the wire can be accurately wound around the winding body of the core. I can make a line.
スピンドルチャックは、ワイヤをコアの一端部側面との間で挟持する支持面と、カット刃とを有し、コアの一端部側面にワイヤを位置決めした状態で、スピンドルチャックの支持面とコアの一端部側面との間でワイヤを挟持し、この状態でワイヤチャックをスピンドルチャック方向に移動させることにより、ワイヤをカット刃に押しつけてカットするのが望ましい。この場合には、ワイヤをカットするカット刃がスピンドルチャックに内蔵されているので、カット刃を駆動するための駆動機構が不要になると共に、カット刃とコアとの位置関係が固定され、カット位置のずれが発生しない。スピンドルチャックとコアとの間でワイヤが挟持されるので、カット後のワイヤに緩みが発生しない。
The spindle chuck has a support surface for clamping the wire between one end side surface of the core and a cutting blade, and the spindle chuck support surface and one end of the core are positioned with the wire positioned on the one end side surface of the core. It is desirable that the wire is pressed against the cutting blade to be cut by sandwiching the wire between the side surfaces and moving the wire chuck in the spindle chuck direction in this state. In this case, since the cutting blade for cutting the wire is built in the spindle chuck, a driving mechanism for driving the cutting blade becomes unnecessary, and the positional relationship between the cutting blade and the core is fixed, and the cutting position is fixed. No deviation occurs. Since the wire is sandwiched between the spindle chuck and the core, the wire after cutting does not loosen.
以上のように、本発明によれば、一定位置で回転するスピンドルチャックに対して、ワイヤノズルとワイヤチャックとを3軸方向に移動させてワイヤの巻線処理、始線部及び終線部の端末処理を行うことができるので、1つのステージで全ての巻線処理を実施できると共に、品種変更にフレキシブルに対応できる。またスピンドルの回転駆動機構を簡素化でき、高精度な回転を実現できる。
As described above, according to the present invention, with respect to the spindle chuck that rotates at a fixed position, the wire nozzle and the wire chuck are moved in the three axial directions to perform the wire winding process, the start line portion, and the end line portion. Since terminal processing can be performed, all winding processes can be performed in one stage, and it is possible to respond flexibly to changes in product type. In addition, the spindle rotation drive mechanism can be simplified and high-precision rotation can be realized.
以下に、本発明の好ましい実施の形態を図面に基づいて説明する。
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

The core chuck 10 includes a pair of chuck claws 11 and 12 that chuck the collar portion 2 of the core 1 in the Z-axis direction. In this embodiment, one chuck claw 11 is a fixed claw, and the other chuck claw 12 is a movable claw that moves in a direction opposite to the fixed claw, but may be configured by a pair of movable claws. The inner surface 11a of the chuck claw 11 is a reference surface in the Z direction. The chuck nail 11 on the fixed side is provided with a support portion 11b that supports the bottom surface of the collar portion 2 of the core 1, and a suction hole 13 for air suction of the core 1 is formed in the support portion 11b. As shown in FIG. 1, the chuck claw 11 is attached to the supply member 16 via a bearing 15, so that the chuck claw 11 is rotatable about the X axis. The movable chuck claw 12 is attached to the supply member 16 so as to be rotatable about a shaft 12a and to be opened and closed in the Z direction by an opening / closing mechanism (not shown). The supply member 16 is moved to convey the core 1 between the core supply / removal position and the winding position shown in FIG. In this embodiment, the movable side chuck claw 12 is attached to the supply member 16, and the chuck claw 12 does not rotate integrally with the fixed side chuck claw 11, but the chuck claw 12 rotates integrally with the chuck claw 11. 11 may be attached.
スピンドルチャック20は、コアチャック10と対峙して配置され、スピンドルチャック20とコアチャック10とは、予め機械精度によってそれらの回転中心が合致するように調整されている。スピンドルチャック20は、図2に示すようにコア1のつば部3をY軸方向にチャックする一対のチャック爪21,22を備えている。この実施形態では、一方のチャック爪21が固定爪であり、他方のチャック爪22が固定爪に対して対向方向に可動する可動爪であるが、一対の可動爪で構成してもよい。チャック爪21の内側面21aがY方向の基準面であり、チャック爪21の底面21bがコア1のつば部3の底面を支持する支持面である。可動側のチャック爪22は固定爪21に対して図示しない開閉機構と共に取り付けられている。チャック爪21の支持面21bの下縁側(Z方向)には、図3に示すように支持面21bより後退した斜面21c又は段差面が形成され、この斜面21cにカット刃23が固定されている。このカット刃23は後述するワイヤチャック42と協動してワイヤ5をカットする機能を備える。なお、支持面21bとつば部3とでワイヤ5を挟持したとき、カット刃23の先端がワイヤ5に接触できるように、支持面21bとカット刃23の先端位置とをほぼ同一高さに揃えるのがよい。
The spindle chuck 20 is disposed so as to face the core chuck 10, and the spindle chuck 20 and the core chuck 10 are adjusted in advance so that their rotational centers coincide with each other according to mechanical accuracy. As shown in FIG. 2, the spindle chuck 20 includes a pair of chuck claws 21 and 22 that chuck the collar portion 3 of the core 1 in the Y-axis direction. In this embodiment, one chuck claw 21 is a fixed claw, and the other chuck claw 22 is a movable claw that moves in a direction opposite to the fixed claw, but may be constituted by a pair of movable claws. The inner surface 21 a of the chuck claw 21 is a reference surface in the Y direction, and the bottom surface 21 b of the chuck claw 21 is a support surface that supports the bottom surface of the collar portion 3 of the core 1. The movable chuck claw 22 is attached to the fixed claw 21 together with an opening / closing mechanism (not shown). On the lower edge side (Z direction) of the support surface 21b of the chuck claw 21, as shown in FIG. 3, an inclined surface 21c or a step surface which is recessed from the support surface 21b is formed, and the cutting blade 23 is fixed to the inclined surface 21c. . The cutting blade 23 has a function of cutting the wire 5 in cooperation with a wire chuck 42 described later. In addition, when the wire 5 is clamped between the support surface 21b and the flange portion 3, the support surface 21b and the tip position of the cut blade 23 are aligned at substantially the same height so that the tip of the cut blade 23 can come into contact with the wire 5. It is good.
図1に示すように、チャック爪21にはX軸方向に延びる回転軸24が連結され、この回転軸24はカップリング25を介してモータ(回転駆動機構)26の駆動軸26aと連結されている。このカップリング25は、両軸間で回転力は伝達するが、軸方向には摺動自在である。回転軸24の中間部は、軸受27を備えた軸受ホルダ28によって回転自在に支持されており、軸受ホルダ28はスライダ29によって設置ベース30上にX軸方向にスライド自在に支持されている。軸受ホルダ28はシリンダ(直線駆動機構)31と連結されており、シリンダ31を駆動することによって軸受ホルダ28と回転軸24とをX軸方向に一体に往復移動させることができる。回転軸24の周囲には圧縮スプリング32が挿通されており、このスプリング32は、スピンドルチャック20と軸受ホルダ28との間に配置されて、スピンドルチャック20をコアチャック10との対向方向に付勢している。回転軸24の軸受ホルダ28より後方側にはストッパ33が固定され、ストッパ33が軸受ホルダ28に当接することにより、スピンドルチャック20の軸受ホルダ28からの突出量が規定されている。
As shown in FIG. 1, a rotation shaft 24 extending in the X-axis direction is connected to the chuck claw 21, and this rotation shaft 24 is connected to a drive shaft 26 a of a motor (rotation drive mechanism) 26 via a coupling 25. Yes. The coupling 25 transmits rotational force between both shafts, but is slidable in the axial direction. An intermediate portion of the rotating shaft 24 is rotatably supported by a bearing holder 28 having a bearing 27, and the bearing holder 28 is supported by a slider 29 so as to be slidable in the X-axis direction. The bearing holder 28 is connected to a cylinder (linear drive mechanism) 31, and by driving the cylinder 31, the bearing holder 28 and the rotary shaft 24 can be reciprocated integrally in the X-axis direction. A compression spring 32 is inserted around the rotary shaft 24, and this spring 32 is disposed between the spindle chuck 20 and the bearing holder 28 and urges the spindle chuck 20 in a direction facing the core chuck 10. is doing. A stopper 33 is fixed to the rear side of the bearing holder 28 of the rotary shaft 24, and the amount of protrusion of the spindle chuck 20 from the bearing holder 28 is defined by the stopper 33 coming into contact with the bearing holder 28.
ワイヤ供給機構40は、図2のように、ワイヤ5を案内するワイヤノズル41と、ワイヤ5をチャック/開放するワイヤチャック42とを備えている。ワイヤノズル41には、図示しないワイヤ供給源からワイヤ5が連続的に供給されている。ワイヤノズル41及びワイヤチャック42には、それぞれ3軸方向に移動させる作動機構43,44が連結されている。スピンドルチャック20でコア1のつば部3をチャックする際、図5の(a)で示すように、ワイヤチャック42でワイヤ5の始端部をチャックし、ワイヤノズル41とワイヤチャック42との間に張り渡されたワイヤ5をコア1のつば部3裏面側に事前に位置決めしておき、ワイヤ5をスピンドルチャック20の支持面21bとコア1のつば部3との間に挟み込むようにする。その状態で、図5の(b),(c)のようにワイヤチャック42をX軸方向に移動させることで、カット刃23によってワイヤ5を引きちぎることができる。この際、ワイヤ5のワイヤチャック側の部分はスピンドルチャック20の斜面21cに入り込むので、ワイヤ5がカット刃23に強く押し付けられ、ワイヤ5を切断しやすくなる。カット刃23は固定されているので、コア1に対するカット位置のズレが発生せず、しかもワイヤ5のテンションはワイヤノズル41に掛からないので、ワイヤ5に伸びや弛みが発生しない。コア1にワイヤ5を巻線した後にワイヤ5の終端部を処理する場合にも、スピンドルチャック20の支持面21bとコア1のつば部3との間にワイヤ5を挟み込むようにし、ワイヤチャック42をX軸方向に移動させることで、カット刃23によってワイヤ5を引きちぎることができる。
2, the wire supply mechanism 40 includes a wire nozzle 41 that guides the wire 5 and a wire chuck 42 that chucks / releases the wire 5. A wire 5 is continuously supplied to the wire nozzle 41 from a wire supply source (not shown). Actuating mechanisms 43 and 44 are connected to the wire nozzle 41 and the wire chuck 42, respectively, to move in three axial directions. When chucking the collar portion 3 of the core 1 with the spindle chuck 20, as shown in FIG. 5A, the wire chuck 42 chucks the start end portion of the wire 5, and between the wire nozzle 41 and the wire chuck 42. The stretched wire 5 is positioned in advance on the back surface side of the flange portion 3 of the core 1, and the wire 5 is sandwiched between the support surface 21 b of the spindle chuck 20 and the flange portion 3 of the core 1. In this state, the wire 5 can be broken by the cutting blade 23 by moving the wire chuck 42 in the X-axis direction as shown in FIGS. At this time, the wire chuck side portion of the wire 5 enters the inclined surface 21c of the spindle chuck 20, so that the wire 5 is strongly pressed against the cutting blade 23 and the wire 5 is easily cut. Since the cutting blade 23 is fixed, no deviation of the cutting position with respect to the core 1 occurs, and the tension of the wire 5 is not applied to the wire nozzle 41, so that the wire 5 does not stretch or slack. Even when the end portion of the wire 5 is processed after the wire 5 is wound around the core 1, the wire 5 is sandwiched between the support surface 21 b of the spindle chuck 20 and the collar portion 3 of the core 1, and the wire chuck 42. Is moved in the X axis direction, the wire 5 can be torn off by the cutting blade 23.
ここで、前記構成よりなる巻線装置による動作手順を、図6にしたがって説明する。なお、図6では説明を簡単にするために、コアチャック10のチャック方向とスピンドルチャック20のチャック方向とを同一方向(Z方向)としているが、実際には直交している。
Here, the operation procedure by the winding apparatus having the above-described configuration will be described with reference to FIG. In FIG. 6, for ease of explanation, the chucking direction of the core chuck 10 and the chucking direction of the spindle chuck 20 are the same direction (Z direction), but are actually orthogonal.
まず、(a)のようにコアチャック10によりコア1のつば部2をZ方向にチャッキングした状態で、コア1をスピンドルチャック20との対向位置へ供給する。この際、コアチャック10はコア1をエア吸引により保持するのがよい。この時点では、ワイヤチャック42はコアチャック10より上方に位置しており、ワイヤ5の始端をチャックしている。
First, as shown in (a), the core 1 is supplied to a position facing the spindle chuck 20 with the collar 2 of the core 1 chucked in the Z direction by the core chuck 10. At this time, the core chuck 10 may hold the core 1 by air suction. At this time, the wire chuck 42 is located above the core chuck 10 and chucks the starting end of the wire 5.
次に(b)のように、ワイヤ5をチャックしたワイヤチャック42をコアチャック10より下方へ移動させ、ワイヤ5をワイヤノズル41から引き出す。そして、ワイヤノズル41とワイヤチャック42とをX方向に移動させて、破線で示すようにワイヤ5の始線部分をコア1のつば部3裏面の所定位置に位置決めする。図7は、ワイヤ5の始線部分をコア1の所定位置に位置決めした様子を示す。
Next, as shown in (b), the wire chuck 42 that has chucked the wire 5 is moved downward from the core chuck 10, and the wire 5 is pulled out from the wire nozzle 41. Then, the wire nozzle 41 and the wire chuck 42 are moved in the X direction, and the starting line portion of the wire 5 is positioned at a predetermined position on the back surface of the collar portion 3 of the core 1 as indicated by a broken line. FIG. 7 shows a state in which the starting line portion of the wire 5 is positioned at a predetermined position of the core 1.
次に(c)のように、スピンドルチャック20を前進させ、ワイヤ5をスピンドルチャック20の支持面21bとコア1のつば部3との間に挟み込む。このとき、ワイヤ5がスピンドルチャック20に内蔵されたカット刃23とつば部3との間に挟み込まれるようにするのが望ましい。
Next, as shown in (c), the spindle chuck 20 is advanced, and the wire 5 is sandwiched between the support surface 21b of the spindle chuck 20 and the collar portion 3 of the core 1. At this time, it is desirable that the wire 5 is sandwiched between the cutting blade 23 built in the spindle chuck 20 and the collar portion 3.
次に(d)のように、コアチャック10を開放すると共に、スピンドルチャック20によりコア1をY方向にチャッキングし、Y方向の位置決めをする。この時、コアチャック10のエア吸引は継続しており、コア1をコアチャック10からスピンドルチャック20に掴み変える間、コア1にずれが生じないようにするのがよい。コア1は最初にコアチャック10によりZ方向に位置決めされ、次にスピンドルチャック20によってY方向に位置決めされるので、コア1の軸心がX軸と同軸になるように正確に位置決めされる。この状態から、スピンドルチャック20に内蔵したカット刃23方向にワイヤチャック42をX方向へ移動させ、ワイヤ5の始線部を引きちぎるようにカットする。
Next, as shown in (d), the core chuck 10 is opened, and the core 1 is chucked in the Y direction by the spindle chuck 20 and positioned in the Y direction. At this time, air suction of the core chuck 10 is continued, and it is preferable that the core 1 is not displaced while the core 1 is gripped from the core chuck 10 to the spindle chuck 20. Since the core 1 is first positioned in the Z direction by the core chuck 10 and then positioned in the Y direction by the spindle chuck 20, the core 1 is accurately positioned so that the axis of the core 1 is coaxial with the X axis. From this state, the wire chuck 42 is moved in the X direction in the direction of the cutting blade 23 built in the spindle chuck 20, and the wire 5 is cut so as to tear.
次に(e)のように、スピンドルチャック20を一定位置で回転駆動させ、ワイヤノズル41をX方向に往復移動させながら、ワイヤ5をコア1に巻き付ける。その際、コアチャック10はスピンドルチャック20の回転駆動力によって追従回転する。コア1はコアチャック10のエア吸引によって保持され、かつスピンドルチャック20の押圧力によりX方向に押されているので、コア1は両端支持された状態で巻線される。そのため、ワイヤ5のテンションが作用しても、回転軸心に対するコア1の傾きを抑制でき、コア1の振れを抑制できる。なお、ワイヤチャック42はワイヤの始線カット終了後、スピンドルチャック20より上方へ移動し、巻線動作に邪魔にならない位置で待機している。
Next, as shown in (e), the spindle chuck 20 is rotationally driven at a fixed position, and the wire 5 is wound around the core 1 while reciprocating the wire nozzle 41 in the X direction. At that time, the core chuck 10 rotates following the rotational driving force of the spindle chuck 20. Since the core 1 is held by air suction of the core chuck 10 and is pressed in the X direction by the pressing force of the spindle chuck 20, the core 1 is wound in a state where both ends are supported. Therefore, even if the tension of the wire 5 acts, the inclination of the core 1 with respect to the rotation axis can be suppressed, and the shake of the core 1 can be suppressed. Note that the wire chuck 42 moves upward from the spindle chuck 20 after completion of the wire start line cutting, and stands by at a position that does not interfere with the winding operation.
コア1への巻線終了後、(f)のように、スピンドルチャック20の開放と共にコアチャック10によりコア1をチャッキングし、スピンドルチャック20を後退させる。
After the winding of the core 1 is completed, the core 1 is chucked by the core chuck 10 as the spindle chuck 20 is opened and the spindle chuck 20 is moved backward as shown in (f).
次に(g)のように、ワイヤチャック42が横方向に移動し、コア1とワイヤノズル41との中間のワイヤ5をチャックする。
Next, as shown in (g), the wire chuck 42 moves in the lateral direction and chucks the wire 5 between the core 1 and the wire nozzle 41.
次に(h)のように、ワイヤチャック42がコアチャック10より下方へ移動すると共にXY方向に移動しながら、コア1に巻線されたワイヤ5の終線部をコア1のつば部3裏面の所定位置に位置決めする。この際、ワイヤノズル41とワイヤチャック42との間のワイヤ5がスピンドルチャック20と干渉しないように、ワイヤノズル41も同様に3軸方向に移動する。図8は、ワイヤ5の終線部分をコア1のつば部3裏面の所定位置に位置決めした様子を示す。
Next, as shown in (h), the wire chuck 42 moves downward from the core chuck 10 and moves in the XY direction, and the end portion of the wire 5 wound around the core 1 is replaced with the back surface of the collar portion 3 of the core 1. Is positioned at a predetermined position. At this time, the wire nozzle 41 similarly moves in the three-axis directions so that the wire 5 between the wire nozzle 41 and the wire chuck 42 does not interfere with the spindle chuck 20. FIG. 8 shows a state in which the end portion of the wire 5 is positioned at a predetermined position on the back surface of the collar portion 3 of the core 1.
次に(i)のように、スピンドルチャック20を再び前進させ、スピンドルチャック20でコア1をチャックし、支持面21bとコア1のつば部3との間にワイヤ5の終線部を挟み込んだ状態で、ワイヤチャック42をX軸方向に移動させ、カット刃23によってワイヤ5の終線部をカットする。
Next, as shown in (i), the spindle chuck 20 is advanced again, the core 1 is chucked by the spindle chuck 20, and the end portion of the wire 5 is sandwiched between the support surface 21b and the collar portion 3 of the core 1. In this state, the wire chuck 42 is moved in the X-axis direction, and the end portion of the wire 5 is cut by the cutting blade 23.
最後に(j)のように、スピンドルチャック20を開放・後退させ、コアチャック10でチャックされた巻線後のコア1(チップコイルC)を、別の取出位置へと搬送する。
Finally, as shown in (j), the spindle chuck 20 is opened and retracted, and the wound core 1 (chip coil C) chucked by the core chuck 10 is transported to another take-out position.
前記実施例では、チップコイルのように一方のつば部裏面にワイヤの始線部と終線部を位置決めする例について説明したが、一方のつば部に端子が突設されている場合にも本発明の巻線装置を適用することができる。特に、ワイヤチャックによってワイヤの先端部を3次元方向に移動させることができるので、ワイヤに弛みを発生させずに端子に巻き付けることができる。
In the above-described embodiment, an example in which the starting and ending portions of the wire are positioned on the back surface of one collar portion as in the case of a chip coil has been explained. The winding device of the invention can be applied. In particular, since the tip of the wire can be moved in a three-dimensional direction by the wire chuck, the wire can be wound around the terminal without causing slack in the wire.
前記実施例では、巻線時にスピンドルチャックとコアチャックとでコアを両端支持したが、巻線時にはコアチャックがコアから離れ、スピンドルチャックだけでコアの一端部をチャックしてもよい。
In the above embodiment, both ends of the core are supported by the spindle chuck and the core chuck at the time of winding. However, at the time of winding, the core chuck may be separated from the core and only one end of the core may be chucked by only the spindle chuck.
前記実施例では、カット刃をスピンドルチャックに内蔵したが、移動可能なカット刃をスピンドルチャックとは別に設けてもよい。その場合には、ワイヤチャックを移動させてワイヤをカット刃に押し付けながら引きちぎる必要はなく、ワイヤノズルとワイヤチャックとの間に張り渡されたワイヤをカット刃でカットすることも可能である。
In the above embodiment, the cutting blade is built in the spindle chuck, but a movable cutting blade may be provided separately from the spindle chuck. In that case, it is not necessary to move the wire chuck and press the wire against the cutting blade and tear it off, and the wire stretched between the wire nozzle and the wire chuck can be cut with the cutting blade.
前記実施例では、コアの一端部をコアチャックでZ方向にチャックして供給した後、コアの他端部をスピンドルチャックでY方向に掴み替えして巻線を行う例を示したが、コアに中心穴が設けられている場合には、スピンドルチャックにコアの中心孔に挿入される軸部を設け、スピンドルチャックの軸部によってコアを挿通支持した状態で巻線を行ってもよい。
In the above embodiment, an example is shown in which after one end of the core is chucked in the Z direction with a core chuck and supplied, the other end of the core is gripped in the Y direction with a spindle chuck to perform winding. If the center hole is provided in the spindle chuck, a shaft portion inserted into the center hole of the core may be provided on the spindle chuck, and the winding may be performed in a state where the core is inserted and supported by the shaft portion of the spindle chuck.
