Description

【0001】
【産業上の利用分野】
本発明は、コイル部品の巻線装置及び巻線方法に関する。
【0002】
【従来の技術】
従来、トランスやインダクタ等のコイル部品にワイヤを巻き回すには、図4、図5に示す方法が知られている。まず、図4▲1▼に示すように、所定位置にセットされたコア1の鍔部2上にノズル3から引き出されたワイヤWを位置決めし、ヒータチップ4を下降させてワイヤWを鍔部2に設けた第1電極(図示せず)上に圧着固定する。次に、図4▲2▼に示すように、ワイヤWの余剰線W’をチャック5で把持し、カットバー6を上昇させる。これにて、余剰線W’がカットされ、この余剰線W’はチャック5によって廃棄される(図4▲3▼参照)。次に、ノズル3を上下動させつつコア1を回転させることによりワイヤWをコア1に巻き回す(図5▲4▼参照)。その後、ワイヤWを鍔部2上に引き出し、再びヒータチップ4を下降させて第2電極(図示せず)上に圧着固定する(図5▲5▼参照)。
【0003】
【発明が解決しようとする課題】
ところで、従来の巻線方法では、1回の巻線処理ごとに必ず余剰線W’が発生し、不経済であった。また、余剰線W’をカットするのにカットバー6、廃棄するのにチャック5が必要であり、それらの駆動機構を含めて設備が複雑化、大型化するという問題点を有していた。
【0004】
そこで、本発明の目的は、余剰線が発生することがなく、かつ、設備を簡略化、小型化できる巻線装置及び巻線方法を提供することにある。
【0005】
【発明の構成及び作用】
以上の目的を達成するため、本発明に係る巻線装置は、ワイヤを電極上に固着する端末処理手段と、挿通されたワイヤの先端部分をコアに対して位置決め及びガイドするノズルと、このノズルの後方に位置してワイヤを把持/解放可能なブレーキと、このブレーキをワイヤの延在方向に往復移動させる移動手段と、前記ノズル、ブレーキ及び移動手段を保持して三次元的に移動させるアーム部材とを備えている。端末処理手段としてはヒータチップを用いることが好ましい。
【0006】
以上の構成からなる巻線装置は次のようにしてコアの胴部にワイヤを巻き回す。但し、この巻線方法に限定されない。
まず、コアの第1電極上にワイヤの始端部を位置させて端末処理手段で固着する。ワイヤを第1電極上に位置させるのはアーム部材の移動による。次にコアの胴部にワイヤを所定のターン数巻き回す。このとき、ブレーキはワイヤを解放しており、かつ、アーム部材の移動によってノズルを適当な位置に移動させて巻き回し処理を行う。この巻き回し処理はコアを回転させるか、コアを固定してアーム部材をコアの周囲で旋回させて行う。
【0007】
次に、巻き回されたワイヤをコアの第2電極上に位置させて端末処理手段で固着する。そして、ブレーキを所定量x後退させてワイヤを把持させ、かつ、ワイヤの終端部を端末処理手段で第2電極上に固着する。さらに、ブレーキを所定量x後退させる。これにてワイヤの終端部が後方に引っ張られてカットされる。
【0008】
その後、ワイヤが巻き回されたコアを巻線処理位置から取り去り、新たなコアを該位置にセットし、ブレーキを所定量x+x前進させる。これにて、前回の巻線処理でカットされたワイヤの終端部がコアの鍔部上に位置し、新たに始端部として第1電極上に固着される。
【0009】
【実施例】
以下、本発明に係る巻線装置及び巻線方法の実施例について添付図面を参照して説明する。
【0010】
図1において、チャック装置10はコア15を保持して回転させる機能を有するもので、装置10自体はロータリ装置(図示せず)に設置されており、コア15を図1に示す巻線処理位置から次の工程位置へと間欠的に移動させる。なお、チャック装置10やロータリ装置は周知である。コア15は胴部16とその上下部に鍔部17,18を備え、鍔部18上には第1電極19a、第2電極19bが設けられている。
【0011】
本巻線装置は、主に、ヒータチップ20とノズル21とブレーキ23と図2に示すアーム25とで構成されている。ワイヤWは図示しない周知の供給装置から引き出され、ガイドレール26からブレーキ23を通じてノズル21に挿通されている。ノズル21はブラケット22を介してアーム25の先端に取付けられている。ブレーキ23は二つのセグメントが図示しないシリンダを駆動源として密着/離間可能であり、ワイヤWを挟着/解放する。また、このブレーキ23はアーム25の水平部分上に設置したガイドレール24上にスライド可能に装着され、図示しない駆動源(例えば、モータ)によってワイヤWの延在方向に所定のストロークで往復移動可能である。アーム25は三次元的に、即ち、ワイヤWの延在方向、これと直交する水平方向及び上下方向に移動可能である。このようにアーム25を三次元的に移動させる装置は種々のものが知られており、その説明は省略する。
【0012】
前記ヒータチップ20は上下動可能であり、常時上方に待機しており、下降することによってワイヤWを電極19a,19b上に熱圧着して固定させる。このヒータチップ20はワイヤWをカットする機能をも有するため、先端部20aはエッジ状であることが好ましい。
【0013】
次に、図3を参照して巻線方法について説明する。
まず、アーム25を駆動してノズル21の先端から引き出されているワイヤWの先端をコア15の第1電極19a上に位置させ、ヒータチップ20を下降させる(図3(a)参照)。これにて、ワイヤWの始端部が第1電極19a上に熱圧着/固定される。
【0014】
次に、ブレーキ23を解放した状態でアーム25を駆動し、ノズル21を所定の巻線位置に移動させつつコア15を回転させる(図3(b)参照)。これにて、ワイヤWがコア15の胴部16に巻き回される。ワイヤWの巻き回しが終了すると、アーム25を駆動してワイヤWを第2電極19b上に位置させ、図3(c)に示すように、ブレーキ23をストロークxだけ後退させ、その位置でブレーキ23を閉じてワイヤWを挟着させる。
【0015】
その後、ヒータチップ20を再度下降させてワイヤWの終端部を第2電極19b上に熱圧着/固定する(図3(d)参照)。そして、ブレーキ23をワイヤWを挟着した状態でストロークxだけ後退させる(図3(e)参照)。このとき、ワイヤWの終端部はヒータチップ20のエッジ部20a(図1参照)部分でカットされる。これにて、コア15に対する巻線が終了する。
【0016】
その後は、前記コア15を巻線処理位置から取り去り、図3(f)に示すように、次のコア15’を巻線処理位置へセットする。そして、ブレーキ23をストロークx+xだけ前進させる(図3(g)参照)。これにて、ワイヤWの先端部が第1電極19a上に位置する。この状態は図3(a)と同じであり、以下、前記と同じ手順でコア15’に対して巻線処理が実行される。
【0017】
以上説明した本実施例によれば、カットされたワイヤの終端部が次回の巻線処理では始端部として使用され、従来のように廃棄せざるを得ない余剰線が発生することはなく、非常に経済的である。また、従来必要とされていたカットバーや廃棄用チャックが不要で、ブレーキ23を設けるだけで済み、設備の面でも簡略化、小型化が達成される。
【0018】
なお、本発明に係る巻線装置及び巻線方法は前記実施例に限定するものではなく、その要旨の範囲内で種々に変更可能である。
特に、ヒータチップ20やブレーキ23の構成は任意である。また、巻き回し処理の際、コア15を回転させるのではなく、ノズル21等を含めてアーム25をコア15を中心として旋回させる方式でもよい。
【0019】
【発明の効果】
以上の説明で明らかなように、本発明によれば、ノズルの後方にワイヤを把時/解放可能なブレーキをワイヤの延在方向に往復移動可能に設けたため、前の巻線処理でカットされたワイヤの終端部を次の巻線処理の始端部として使用でき、余剰線は全く発生することがなく、経済的である。また、ブレーキを新たに設けるだけでよく、従来必要とされていたカットバー、廃棄用チャックが不要となり、設備のコンパクト化を達成できる。

[Industrial applications]
The present invention relates to a winding device and a winding method for a coil component.
[0002]
[Prior art]
Conventionally, a method shown in FIGS. 4 and 5 is known for winding a wire around a coil component such as a transformer or an inductor. First, as shown in FIG. 4 (1), the wire W drawn out of the nozzle 3 is positioned on the flange 2 of the core 1 set at a predetermined position, and the heater chip 4 is lowered to connect the wire W to the flange. 2 is pressed and fixed on a first electrode (not shown) provided on the second electrode. Next, as shown in FIG. 4B, the excess wire W ′ of the wire W is gripped by the chuck 5 and the cut bar 6 is raised. Thus, the surplus line W 'is cut, and the surplus line W' is discarded by the chuck 5 (see FIG. 4 (3)). Next, the wire W is wound around the core 1 by rotating the core 1 while moving the nozzle 3 up and down (see FIG. 5 (4)). Thereafter, the wire W is pulled out onto the flange portion 2, and the heater chip 4 is lowered again to be fixed by pressure bonding on a second electrode (not shown) (see FIG. 5 (5)).
[0003]
[Problems to be solved by the invention]
By the way, in the conventional winding method, a surplus wire W 'is always generated for each winding processing, which is uneconomical. Further, a cut bar 6 is required to cut the surplus line W ', and a chuck 5 is required to discard the surplus line W', and there has been a problem that the equipment including the driving mechanism thereof becomes complicated and large.
[0004]
Therefore, an object of the present invention is to provide a winding device and a winding method that do not generate extra wires and that can simplify and reduce equipment.
[0005]
Configuration and Function of the Invention
In order to achieve the above object, a winding device according to the present invention includes a terminal processing means for fixing a wire on an electrode, a nozzle for positioning and guiding a distal end portion of an inserted wire with respect to a core, , A brake capable of gripping / releasing the wire, a moving means for reciprocating the brake in the extending direction of the wire, and an arm for holding the nozzle, the brake and the moving means and moving three-dimensionally And a member. It is preferable to use a heater chip as the terminal processing means.
[0006]
The winding device having the above configuration winds a wire around the body of the core as follows. However, it is not limited to this winding method.
First, the starting end of the wire is positioned on the first electrode of the core and fixed by the terminal processing means. The position of the wire on the first electrode is due to the movement of the arm member. Next, the wire is wound around the body of the core for a predetermined number of turns. At this time, the brake releases the wire and moves the nozzle to an appropriate position by the movement of the arm member to perform the winding process. This winding process is performed by rotating the core or by fixing the core and rotating the arm member around the core.
[0007]
Next, the wound wire is positioned on the second electrode of the core, and is fixed by terminal processing means. Then, the brake by a predetermined amount x 1 retracted to grip the wire and to secure the end of the wire on the second electrode in the terminal processing unit. Further, the brake by a predetermined amount x 2 retracted. As a result, the end of the wire is pulled rearward and cut.
[0008]
Thereafter, the core around which the wire is wound is removed from the winding processing position, a new core is set at the position, and the brake is advanced by a predetermined amount x 1 + x 2 . As a result, the terminal end of the wire cut in the previous winding process is located on the flange of the core, and is newly fixed on the first electrode as a start end.
[0009]
【Example】
Hereinafter, embodiments of a winding device and a winding method according to the present invention will be described with reference to the accompanying drawings.
[0010]

Note that the chuck device 10 and the rotary device are well known. The core 15 includes a body 16 and upper and lower flanges 17 and 18, and a first electrode 19 a and a second electrode 19 b are provided on the flange 18.
[0011]
The winding device mainly includes a heater chip 20, a nozzle 21, a brake 23, and an arm 25 shown in FIG. The wire W is drawn out from a known supply device (not shown), and is inserted into the nozzle 21 from the guide rail 26 through the brake 23. The nozzle 21 is attached to the tip of an arm 25 via a bracket 22. The brake 23 has two segments that can be brought into close contact with and separated from each other by using a cylinder (not shown) as a drive source, and clamps / releases the wire W. The brake 23 is slidably mounted on a guide rail 24 installed on a horizontal portion of the arm 25, and can be reciprocated at a predetermined stroke in a direction in which the wire W extends by a driving source (eg, a motor) not shown. It is. The arm 25 can move three-dimensionally, that is, in the extending direction of the wire W, in the horizontal direction perpendicular to the wire W, and in the vertical direction. Various devices are known for three-dimensionally moving the arm 25 in this manner, and a description thereof will be omitted.
[0012]
The heater chip 20 can be moved up and down, and is always on standby, and is lowered to fix the wire W on the electrodes 19a and 19b by thermocompression. Since the heater chip 20 also has a function of cutting the wire W, it is preferable that the distal end portion 20a has an edge shape.
[0013]
Next, a winding method will be described with reference to FIG.
First, the arm 25 is driven to position the tip of the wire W pulled out from the tip of the nozzle 21 on the first electrode 19a of the core 15, and the heater chip 20 is lowered (see FIG. 3A). Thereby, the starting end of the wire W is thermocompression-bonded / fixed on the first electrode 19a.
[0014]
Next, the arm 25 is driven with the brake 23 released, and the core 15 is rotated while moving the nozzle 21 to a predetermined winding position (see FIG. 3B). Thereby, the wire W is wound around the trunk 16 of the core 15. When winding the wire W is completed, by driving the arm 25 to position the wire W on the second electrode 19b, as shown in FIG. 3 (c), to retract the brake 23 by the stroke x 1, in that position The brake 23 is closed to clamp the wire W.
[0015]
Thereafter, the heater chip 20 is lowered again, and the terminal end of the wire W is thermocompression-bonded / fixed on the second electrode 19b (see FIG. 3D). Then, to retract the brake 23 while clamped to the wire W by a stroke x 2 (see FIG. 3 (e)). At this time, the end of the wire W is cut at the edge 20a (see FIG. 1) of the heater chip 20. Thus, the winding on the core 15 is completed.
[0016]
Thereafter, the core 15 is removed from the winding processing position, and the next core 15 'is set to the winding processing position as shown in FIG. Then, to advance the brake 23 by a stroke x 1 + x 2 (see FIG. 3 (g)). Thus, the tip of the wire W is located on the first electrode 19a. This state is the same as that in FIG. 3A, and thereafter, the winding process is performed on the core 15 ′ in the same procedure as described above.
[0017]
According to the present embodiment described above, the end portion of the cut wire is used as the start end portion in the next winding process, and there is no surplus wire that has to be discarded unlike the related art. It is economical. Further, a cut bar and a disposal chuck, which are conventionally required, are not necessary, and only the brake 23 is required, and simplification and downsizing of equipment can be achieved.
[0018]
The winding device and the winding method according to the present invention are not limited to the above-described embodiment, but can be variously modified within the scope of the gist.
In particular, the configurations of the heater chip 20 and the brake 23 are arbitrary. Further, in the winding process, the arm 25 including the nozzle 21 and the like may be turned around the core 15 instead of rotating the core 15.
[0019]
【The invention's effect】
As is apparent from the above description, according to the present invention, since the brake capable of gripping / releasing the wire is provided at the rear of the nozzle so as to be able to reciprocate in the extending direction of the wire, the brake is cut in the previous winding process. The end of the wire can be used as the beginning of the next winding process, and no surplus wire is generated, which is economical. In addition, it is only necessary to newly provide a brake, and a cut bar and a discarding chuck, which are conventionally required, are not required, and the equipment can be downsized.
