Description

本発明は、溶接方法に係り、より詳しくは、絶縁板を間として両面に重ね合わせた第１金属部材と第２金属部材とを電気的に接続する際の溶接方法に関する。   The present invention relates to a welding method, and more particularly, to a welding method when electrically connecting a first metal member and a second metal member that are superposed on both sides with an insulating plate interposed therebetween.

従来、電子部品において、絶縁板を間として銅箔等の第１金属部材と第２金属部材とを両面に重ね合わせたものが存在する。このような電子部品では、第１金属部材と第２金属部材とを電気的に接続する場合があるが、これらを溶接により直接的に接続するのは非常に困難であった。そこで、従来、絶縁板の両面の第１金属部材と第２金属部材とを電気的に接続するには、絶縁板に貫通孔を形成し、その貫通孔に金属製の接合部材を挿通して、かしめる方法がとられていた。また、他の方法として、半田付けによる方法や、絶縁板に形成した貫通孔に導電性ペーストを充填し、この導電性ペーストを経由して絶縁板の両面に重ね合わせた第１金属部材と第２金属部材とを電気的に接続する方法も行なわれていた（例えば、特許文献１参照）。
特開平６−２０９１４８号公報 Conventionally, there is an electronic component in which a first metal member such as a copper foil and a second metal member are overlapped on both surfaces with an insulating plate interposed therebetween. In such an electronic component, the first metal member and the second metal member may be electrically connected, but it is very difficult to connect them directly by welding. Therefore, conventionally, in order to electrically connect the first metal member and the second metal member on both sides of the insulating plate, a through hole is formed in the insulating plate, and a metal joining member is inserted into the through hole. The method of caulking was taken. In addition, as another method, the first metal member and the first metal member which are overlapped on both surfaces of the insulating plate through the conductive paste filled with the conductive paste in the through hole formed in the insulating plate as the method by soldering. A method of electrically connecting two metal members has also been performed (see, for example, Patent Document 1).
JP-A-6-209148

しかしながら、絶縁板の貫通孔に金属製の接合部材を挿通してかしめる従来の接続方法では、接合不良が多かった。また、インピーダンスや抵抗のばらつきも大きく、品質が安定しなかった。また、従来では、絶縁板に貫通孔を形成する工程と、貫通孔に金属製の接合部材を挿通してかしめる工程とは、極めて短時間に連続的に行なうことが困難であった。これにより、製造時の作業時間の短縮を図ることが困難であった。また、上記特許文献１のような導電性ペーストを用いる方法でも、同様に、絶縁板に貫通孔を形成する工程や、貫通孔に導電性ペーストを充填する工程等を、極めて短時間に連続的に行なうことが困難であった。
そこで、本発明は、絶縁板の両面に重ね合わせた第１金属部材と第２金属部材とを電気的に接続した部品の品質を安定かつ向上させると共に、製造時の作業時間を短縮し得る溶接方法を提供することを目的とする。 However, in the conventional connection method in which a metal bonding member is inserted into the through hole of the insulating plate and caulked, there are many bonding defects. In addition, variations in impedance and resistance were large, and the quality was not stable. Conventionally, it has been difficult to continuously perform the step of forming a through hole in an insulating plate and the step of caulking a metal joining member through the through hole in a very short time. As a result, it has been difficult to reduce the working time during manufacturing. Similarly, in the method using the conductive paste as in Patent Document 1, the process of forming the through hole in the insulating plate, the process of filling the through hole with the conductive paste, and the like are performed continuously in a very short time. It was difficult to do.
Accordingly, the present invention provides welding that can stably and improve the quality of a component in which the first metal member and the second metal member that are overlapped on both surfaces of the insulating plate are electrically connected, and can reduce the work time during manufacturing. It aims to provide a method.

上記目的を達成するために、本発明に係る溶接方法は、熱可塑性の樹脂絶縁板を間として両面に第１金属部材・第２金属部材を重ね合わせて、加熱状態の第１電極と第２電極とを押圧して、接合予定部位において上記樹脂絶縁板を軟化しつつ周囲へ追いやり、上記第１金属部材と上記第２金属部材とを上記接合予定部位にて接触状態として電流を流し、該第１金属部材と該第２金属部材とを抵抗溶接するものである。
また、上記第１電極・第２電極に、夫々、抵抗溶接とは異なる別の電源からの電流を流して上記加熱状態とする。
また、上記第１電極・第２電極に付設した電気ヒータにて上記加熱状態とする。 In order to achieve the above object, a welding method according to the present invention includes a first electrode and a second electrode in a heated state, with a first metal member and a second metal member overlapped on both sides with a thermoplastic resin insulating plate in between. The electrode is pressed, the resin insulating plate is softened at the site to be joined and driven to the surroundings, the first metal member and the second metal member are brought into contact at the site to be joined, and a current is passed, The first metal member and the second metal member are resistance welded.
In addition, a current from a different power source different from the resistance welding is applied to the first electrode and the second electrode, respectively, so that the heating state is achieved.
Moreover, it is set as the said heating state with the electric heater attached to the said 1st electrode and 2nd electrode.

本発明は、次のような著大な効果を奏する。
本発明に係る溶接方法は、インピーダンスや抵抗のばらつきを小さくすることができ、品質を安定かつ向上させることができる。
また、樹脂絶縁板を軟化しつつ周囲へ追いやる工程と、第１金属部材と第２金属部材とを抵抗溶接する工程との２工程を、極めて短時間に連続して行なうことができ、製造時の作業時間を短縮することができる。また、作業に必要な装置が複雑になることもない。
また、第１電極と第２電極とを加熱状態にするための構造を簡単にすることができる。 The present invention has the following remarkable effects.
The welding method according to the present invention can reduce variations in impedance and resistance, and can stably and improve quality.
Also, the two steps of the process of softening the resin insulating plate to the surroundings and the step of resistance welding the first metal member and the second metal member can be performed continuously in a very short time. The work time can be shortened. Moreover, the apparatus required for work does not become complicated.
Moreover, the structure for heating the first electrode and the second electrode can be simplified.

また、第１電極と第２電極とを加熱状態にするための電気回路と、第１電極と第２電極に電流を流して抵抗溶接するための電気回路とを完全に独立させることができ、安全性の高い溶接方法とすることができる。   In addition, the electric circuit for heating the first electrode and the second electrode and the electric circuit for resistance welding by flowing a current through the first electrode and the second electrode can be completely independent, It can be set as a highly safe welding method.

以下、実施の形態を示す図面に基づき本発明を詳説する。
図１に於て、本発明の実施の一形態に係る溶接方法は、熱可塑性の樹脂絶縁板１を間として両面に第１金属部材２・第２金属部材３を重ね合わせた部品10について、抵抗溶接により、第１金属部材２と第２金属部材３とを電気的に接続する方法である。
具体的には、本実施形態に係る溶接方法は、図２に於て示すように、例えばクレジットカード用のＩＣにアンテナがついた部品10を製造する際に用いられる。ここで、部品10の一方面側に配設される第１金属部材２，２は、アンテナとなる部材であり、帯状の銅箔にて形成されている。また、第１金属部材２，２の端部であると共に他方面側の第２金属部材３と電気的に接続する接合予定部位Ａ1 , Ａ2 では、第１金属部材２の形状は略丸型となっている。
また、部品10の他方面側に配設される第２金属部材３は、例えば厚さ20μm 〜40μm の銅箔にて形成されている。また、部品10の熱可塑性の樹脂絶縁板１は、例えば、ＰＥＴ材（ポリエチレンテレフタレート）により形成されている。 Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
In FIG. 1, a welding method according to an embodiment of the present invention includes a component 10 in which a first metal member 2 and a second metal member 3 are overlapped on both sides with a thermoplastic resin insulating plate 1 in between. In this method, the first metal member 2 and the second metal member 3 are electrically connected by resistance welding.
Specifically, as shown in FIG. 2, the welding method according to the present embodiment is used when, for example, a component 10 having an antenna attached to a credit card IC is manufactured. Here, the first metal members 2 and 2 disposed on one side of the component 10 are members that serve as antennas, and are formed of a strip-shaped copper foil. In addition, the shape of the first metal member 2 is substantially round at the joining portions A 1 and A 2 which are the end portions of the first metal members 2 and 2 and are electrically connected to the second metal member 3 on the other surface side. It is a type.
The second metal member 3 disposed on the other surface side of the component 10 is formed of, for example, a copper foil having a thickness of 20 μm to 40 μm. Further, the thermoplastic resin insulating plate 1 of the component 10 is formed of, for example, a PET material (polyethylene terephthalate).

20は、図１に示すように、本発明の実施の一形態に係る溶接方法を行なうための溶接装置を示す。この溶接装置20は、倒立略Ｕ字型の第１電極５と略Ｕ字型の第２電極６とを備えている。第１電極５と第２電極６は、部品10を間とするように上下に対向配置され、相互に接近離間自在（図１の矢印Ｂ方向）に構成されている。また、第１電極５と第２電極６とは、電気抵抗が大きな金属にて形成されている。また、第１電極５と第２電極６は、抵抗溶接するための電流Ｉ0 を流す電源となると共に制御を行なう電源部８と、電気的に接続されている。また、第１電極５と第２電極６は、夫々、交流の電源７と電気的に接続されている。これにより、第１電極５・第２電極６に、夫々、抵抗溶接とは異なる別の電源７，７からの電流Ｉ1 ，Ｉ2 を流して第１電極５・第２電極６を加熱状態とすることができるように構成されている。 As shown in FIG. 1, 20 shows the welding apparatus for performing the welding method which concerns on one Embodiment of this invention. The welding apparatus 20 includes an inverted substantially U-shaped first electrode 5 and a substantially U-shaped second electrode 6. The first electrode 5 and the second electrode 6 are arranged so as to face each other with the component 10 therebetween, and are configured to be close to and away from each other (in the direction of arrow B in FIG. 1). The first electrode 5 and the second electrode 6 are made of a metal having a large electric resistance. In addition, the first electrode 5 and the second electrode 6 are electrically connected to a power supply unit 8 that controls and controls the current I 0 for resistance welding. The first electrode 5 and the second electrode 6 are electrically connected to an AC power source 7, respectively. As a result, currents I 1 and I 2 from different power sources 7 and 7 different from resistance welding are passed through the first electrode 5 and the second electrode 6, respectively, to heat the first electrode 5 and the second electrode 6. It is comprised so that it can be.

次に、図１，図３〜図８を参照して、上述した溶接装置20を用いた溶接方法について具体的に説明する。
まず、図１及び図３に於て示すように、熱可塑性の樹脂絶縁板１を間として両面に第１金属部材２・第２金属部材３を重ね合わせた状態でかつ未溶接の部品10を、図示省略の搬送手段にて溶接装置20の第１電極５と第２電極６との間に搬送する。
次に、電源７，７にて第１電極５と第２電極６に電流Ｉ1 ，Ｉ2 を流して加熱状態とする。そして、図４に於て示すように、加熱状態の第１電極５と第２電極６とを押圧して（図４の矢印Ｆ方向）、接合予定部位Ａ1 において樹脂絶縁板１を軟化しつつ周囲へ追いやる（図４の矢印Ｄ方向）。 Next, a welding method using the welding apparatus 20 described above will be specifically described with reference to FIGS.
First, as shown in FIG. 1 and FIG. 3, the unwelded component 10 is formed with the first metal member 2 and the second metal member 3 overlapped on both surfaces with the thermoplastic resin insulating plate 1 in between. Then, it is transported between the first electrode 5 and the second electrode 6 of the welding apparatus 20 by a transport means (not shown).
Next, currents I 1 and I 2 are passed through the first electrode 5 and the second electrode 6 by the power sources 7 and 7 to bring them into a heated state. Then, as shown in FIG. 4, the heated first electrode 5 and the second electrode 6 are pressed (in the direction of arrow F in FIG. 4), and the resin insulating plate 1 is softened at the joining portion A 1 . While driving around (arrow D direction in FIG. 4).

そして、第１金属部材２と第２金属部材３とを接合予定部位Ａ1 にて接触状態として、その直後に、図１及び図５に於て示すように、電源部８から電流Ｉ0 を流し（図５の矢印Ｉ0 方向）、第１金属部材２と第２金属部材３とを抵抗溶接する。
なお、上述のように、樹脂絶縁板１を軟化しつつ周囲へ追いやる工程と、第１金属部材２と第２金属部材３とを抵抗溶接する２つの工程は、同じ第１電極５と第２電極６を用いて行なわれる。また、第１電極５と第２電極６が樹脂絶縁板１に接近し、離れる動作を１回行なう間に、上記２工程が行なわれる。従って、この２工程は、極めて短時間に連続して行なわれる。 Then, a contact state and a first metallic member 2 and the second metallic member 3 at predetermined joining portions A 1, and immediately thereafter, as shown At a 1 and 5, the current I 0 from the power supply unit 8 The first metal member 2 and the second metal member 3 are resistance-welded with the sink (in the direction of arrow I 0 in FIG. 5).
As described above, the step of driving the resin insulating plate 1 to the surrounding while being softened and the two steps of resistance welding the first metal member 2 and the second metal member 3 are the same as the first electrode 5 and the second electrode. This is performed using the electrode 6. Further, the above two steps are performed while the first electrode 5 and the second electrode 6 approach the resin insulating plate 1 and perform the operation of separating once. Therefore, these two steps are performed continuously in a very short time.

次に、図６及び図７に於て示すように、第１電極５と第２電極６とを、もう一方の接合予定部位Ａ2 側に移動させ、上述した作業を再び行なう。即ち、加熱状態の第１電極５と第２電極６とを押圧して（図６の矢印Ｆ方向）、接合予定部位Ａ2 において樹脂絶縁板１を軟化しつつ周囲へ追いやり（図６の矢印Ｄ方向）、第１金属部材２と第２金属部材３とを接合予定部位Ａ2 にて接触状態として電流Ｉ0 を流し（図７の矢印Ｉ0 方向）、第１金属部材２と第２金属部材３とを抵抗溶接する。
こうして、図８に於て示すように、熱可塑性の樹脂絶縁板１の両面の第１金属部材２と第２金属部材３とは、電気的に接続される。 Next, as shown in FIGS. 6 and 7, the first electrode 5 and the second electrode 6 are moved to the other site to be joined A 2 , and the above-described operation is performed again. That is, the heated first electrode 5 and the second electrode 6 are pressed (in the direction of arrow F in FIG. 6), and the resin insulating plate 1 is softened at the planned joining portion A 2 and driven to the surroundings (arrow in FIG. 6). D direction), the first metal member 2 and the second metal member 3 are brought into contact with each other at the part A 2 to be joined, and a current I 0 is passed (in the direction of arrow I 0 in FIG. 7). The metal member 3 is resistance welded.
Thus, as shown in FIG. 8, the first metal member 2 and the second metal member 3 on both surfaces of the thermoplastic resin insulating plate 1 are electrically connected.

次に、図９に於て、第１電極及び第２電極の他の加熱方法を説明するための全体概略正面図を示す。この図９に於ける溶接装置21では、図１の溶接装置20のように電源７，７にて第１電極５と第２電極６に電流Ｉ1 ，Ｉ2 を流して加熱状態とするのではなく、電気ヒータ４にて加熱状態とする場合を例示している。より具体的には、溶接装置21は、第１電極５・第２電極６に付設した棒状の電気ヒータ４にて、第１電極５と第２電極６とを加熱状態とするように構成されている。その他の構成は、図１に示した溶接装置20と同様である。 Next, FIG. 9 shows an overall schematic front view for explaining another heating method of the first electrode and the second electrode. In the welding apparatus 21 in FIG. 9, as in the welding apparatus 20 in FIG. 1, currents I 1 and I 2 are supplied to the first electrode 5 and the second electrode 6 by the power sources 7 and 7 to be in a heated state. Instead, the case where the electric heater 4 is used for heating is illustrated. More specifically, the welding apparatus 21 is configured so that the first electrode 5 and the second electrode 6 are heated by the rod-shaped electric heater 4 attached to the first electrode 5 and the second electrode 6. ing. Other configurations are the same as those of the welding apparatus 20 shown in FIG.

なお、本発明は、上述の実施の形態に限定されず、本発明の要旨を逸脱しない範囲で設計変更可能である。例えば、本実施形態では、樹脂絶縁板１は、ＰＥＴ材（ポリエチレンテレフタレート）により形成されている場合を例示したが、本発明はこれに限らず、他の種類の熱可塑性樹脂から形成されていてもよい。
また、第１電極５及び第２電極６の形状は、略Ｕ字型（倒立略Ｕ字型）に形成するものに限るのではなく、例えば略Ｖ字型（倒立略Ｖ字型）等の形状に形成してもよい。
また、電気ヒータ４の形状は、棒状に限るのではなく、コイル状としてもよい。
また、第１金属部材２と第２金属部材３とは、銅箔に限らず、他の種類の金属であってもよい。 The present invention is not limited to the above-described embodiment, and the design can be changed without departing from the gist of the present invention. For example, in the present embodiment, the case where the resin insulating plate 1 is formed of a PET material (polyethylene terephthalate) is exemplified, but the present invention is not limited to this and is formed of other types of thermoplastic resins. Also good.
Further, the shapes of the first electrode 5 and the second electrode 6 are not limited to those formed in a substantially U shape (inverted substantially U shape), but may be, for example, a substantially V shape (inverted substantially V shape). You may form in a shape.
The shape of the electric heater 4 is not limited to a rod shape, and may be a coil shape.
The first metal member 2 and the second metal member 3 are not limited to copper foil, but may be other types of metals.

以上のように本発明に係る溶接方法は、熱可塑性の樹脂絶縁板１を間として両面に第１金属部材２・第２金属部材３を重ね合わせて、加熱状態の第１電極５と第２電極６とを押圧して、接合予定部位Ａ1 ，Ａ2 において樹脂絶縁板１を軟化しつつ周囲へ追いやり、第１金属部材２と第２金属部材３とを接合予定部位Ａ1 ，Ａ2 にて接触状態として電流Ｉ0 を流し、第１金属部材２と第２金属部材３とを抵抗溶接するので、他の部材を介することなく直接的に第１金属部材２と第２金属部材３とを接触させて、第１金属部材２と第２金属部材３とを電気的に接続することができる。これにより、接合部材や導電性ペースト等の他の部材を介して電気的に接続していた従来と比較して、インピーダンスや抵抗のばらつきを小さくすることができる。その結果、樹脂絶縁板１の両面に重ね合わせた第１金属部材２と第２金属部材３とを電気的に接続した部品の品質を、安定かつ向上させることができる。 As described above, in the welding method according to the present invention, the first metal member 2 and the second metal member 3 are overlapped on both surfaces with the thermoplastic resin insulating plate 1 in between, and the first electrode 5 and the second electrode in the heated state are overlapped. by pressing the electrode 6, the predetermined joining portions a 1, a 2 Oiyari to ambient while softening the resin insulating plate 1, predetermined joining portions a 1 and the first metal member 2 and the second metal member 3, a 2 Since the current I 0 flows as a contact state and the first metal member 2 and the second metal member 3 are resistance-welded, the first metal member 2 and the second metal member 3 are directly connected without passing through other members. The first metal member 2 and the second metal member 3 can be electrically connected. Thereby, the dispersion | variation in an impedance and resistance can be made small compared with the former which was electrically connected through other members, such as a joining member and an electrically conductive paste. As a result, the quality of the component in which the first metal member 2 and the second metal member 3 superimposed on both surfaces of the resin insulating plate 1 are electrically connected can be stably and improved.

また、第１電極５と第２電極６にて、樹脂絶縁板１を軟化しつつ周囲へ追いやる工程と、第１金属部材２と第２金属部材３とを抵抗溶接する工程との２工程を、極めて短時間に連続して行なうことができる。これにより、絶縁板に貫通孔を形成する工程と、接合部材や導電性ペーストにて絶縁板の両面の第１金属部材と第２金属部材とを電気的に接続する工程と、を極めて短時間に連続的に行なうのが困難であった従来と比較して、製造時の作業時間を短縮することができる。また、作業に必要な溶接装置20, 21の構造が複雑になることもない。   Further, the first electrode 5 and the second electrode 6 are used to perform two steps, that is, the step of driving the resin insulating plate 1 to the surroundings while softening the resin insulating plate 1 and the step of resistance welding the first metal member 2 and the second metal member 3. Can be carried out continuously in a very short time. Thereby, the process of forming a through-hole in an insulating plate and the process of electrically connecting the first metal member and the second metal member on both surfaces of the insulating plate with a bonding member or a conductive paste are extremely short. Compared to the conventional method that is difficult to perform continuously, the working time at the time of manufacture can be shortened. Further, the structure of the welding devices 20 and 21 necessary for the work is not complicated.

また、第１電極５・第２電極６に、夫々、抵抗溶接とは異なる別の電源７，７からの電流Ｉ1 ，Ｉ2 を流して加熱状態とすることによって、第１電極５・第２電極６にヒータ４を付設してそのヒータ４にて加熱状態とする場合と比較して、第１電極５と第２電極６とを加熱状態にするための構造を簡単にすることができる。また、第１電極５と第２電極６とを直接的に加熱するので、適温に加熱するまでの時間を短くすることができる。 In addition, the first electrode 5 and the second electrode 6 are heated by flowing currents I 1 and I 2 from different power sources 7 and 7 different from resistance welding, respectively, so that the first electrode 5 and the second electrode 6 are heated. Compared with the case where the heater 4 is attached to the two electrodes 6 and the heater 4 is heated, the structure for bringing the first electrode 5 and the second electrode 6 into a heated state can be simplified. . Moreover, since the 1st electrode 5 and the 2nd electrode 6 are heated directly, the time until it heats to appropriate temperature can be shortened.

また、第１電極５・第２電極６に付設した電気ヒータ４にて加熱状態とすることによって、第１電極５と第２電極６には、電気ヒータ４の電流が流れないようにすることができる。即ち、第１電極５と第２電極６とを加熱状態にするための電気回路と、第１電極５と第２電極６に電流Ｉ0 を流して抵抗溶接するための電気回路とを完全に独立させることができるので、電気ヒータ４の電流と抵抗溶接の電流Ｉ0 とが同時に第１電極５・第２電極６に流れるトラブルを防止することができる。その結果、安全性の高い溶接方法とすることができる。 In addition, the electric heater 4 attached to the first electrode 5 and the second electrode 6 is heated to prevent the electric current of the electric heater 4 from flowing through the first electrode 5 and the second electrode 6. Can do. That is, an electric circuit for heating the first electrode 5 and the second electrode 6 and an electric circuit for resistance welding by flowing a current I 0 through the first electrode 5 and the second electrode 6 are completely provided. Since they can be made independent, it is possible to prevent troubles in which the current of the electric heater 4 and the resistance welding current I 0 flow to the first electrode 5 and the second electrode 6 at the same time. As a result, a highly safe welding method can be obtained.
