Description

本発明は、例えば鉛蓄電池の端子の如き、蓄電池用端子の製造方法に関するものである。   The present invention relates to a method for manufacturing a storage battery terminal, such as a lead storage battery terminal.

従来、例えば鉛蓄電池用端子を製造する場合、図２に示すように鉛蓄電の電槽蓋１に埋設された中空円筒状のブッシング端子２内に端子極柱３を挿着した後、フラックスを含浸させた刷毛４やスポンジにより、図２のように端子極柱３の頂部にフラックスを塗布し、しかる後バーナー等の加熱手段にて加熱して溶接して、図３に示すようにブッシング端子２と端子極柱３の頂部とを一体化して蓄電池用の端子を形成していた。   Conventionally, for example, when manufacturing a lead storage battery terminal, as shown in FIG. 2, after inserting a terminal pole column 3 into a hollow cylindrical bushing terminal 2 embedded in a battery case lid 1 for lead storage, With the impregnated brush 4 or sponge, a flux is applied to the top of the terminal pole 3 as shown in FIG. 2, and then heated and welded by a heating means such as a burner, as shown in FIG. 2 and the top of the terminal pole 3 are integrated to form a terminal for a storage battery.

あるいはまた端子極柱３の頂部に凹部を設けてこれにフラックスを充填し、かつブッシング端子２と端子極柱３の各頂部に各々電極を取り付け、かつまたブッシング端子２の側面に絶縁性治具を当接した後、前記電極間に電流を流してブッシング端子２と端子極柱３の両頂部部分を溶接する方法も提案されていた（特許文献１）。
特開平２−２３４３４７号公報 Alternatively, a recess is provided at the top of the terminal pole 3 and filled with flux, and electrodes are attached to the tops of the bushing terminal 2 and the terminal pole 3, respectively, and an insulating jig is provided on the side of the bushing terminal 2. There has also been proposed a method in which a current is passed between the electrodes and the top portions of the bushing terminal 2 and the terminal pole column 3 are welded after the contact is made (Patent Document 1).
JP-A-2-234347

ところで前記図２に示す方法のように、フラックスを含浸させた刷毛４やスポンジでフラックスを端子極柱３の頂部に塗布する方法では、端子極柱３の頂部のみにフラックスを塗布することは困難で、度々ブッシング端子２の頂部や側面へもフラックスを塗布してしまっていた。加えて、この図２に示す方法では、端子極柱３の頂部へのフラックスの塗布量の制御が難しく、フラックスを多めに塗布してしまうことが多かった。   By the way, as in the method shown in FIG. 2, it is difficult to apply the flux only to the top of the terminal pole column 3 by the method of applying the flux to the top of the terminal pole column 3 with the brush 4 or sponge impregnated with the flux. Thus, the flux is often applied to the top and side surfaces of the bushing terminal 2. In addition, in the method shown in FIG. 2, it is difficult to control the amount of flux applied to the top of the terminal pole 3, and the flux is often applied excessively.

このようにフラックスを端子極柱３の頂部だけでなく、ブッシング端子２の頂部や側面にまで塗布したり、あるいは多めに塗布してしまうと、溶接後フラックスが残留し、端子の頂部あるいは側面５にヌメリが発生し、出来上がったこの端子に負荷端子を接続した際、このヌメリが原因で負荷端子が回動して端子から抜け易くなる、という問題があった。   As described above, if the flux is applied not only to the top of the terminal pole 3 but also to the top or side of the bushing terminal 2 or excessively applied, the flux remains after welding and the top or side 5 of the terminal. When the load terminal is connected to the completed terminal, there is a problem that the load terminal is rotated due to the slime and is easily detached from the terminal.

そのため、溶接後出来上がった端子の表面を研磨し、残留フラックスを取り除かねばならなかった。   For this reason, the surface of the terminal completed after welding had to be polished to remove residual flux.

また特許文献１に記載の方法では、溶接作業の前に、予め端子極柱３の頂部に凹部を設け、これにフラックスを充填しておく必要があったり、かつブッシング端子２と端子極柱３の各頂部に各々電極を取り付け、さらにはブッシング端子２の側面に絶縁性治具を当接しなければならない等多くの準備が必要で、端子の製造が大変であった。   Further, in the method described in Patent Document 1, it is necessary to provide a concave portion at the top of the terminal pole column 3 in advance and fill it with flux before welding work, and the bushing terminal 2 and the terminal pole column 3. Many preparations such as attaching an electrode to each of the tops of each of the wires and abutting an insulating jig on the side surface of the bushing terminal 2 are necessary, and the manufacture of the terminals was difficult.

前記問題に鑑み本発明の目的は、端子極柱頂部にのみフラックスを正確に塗布できるとともに、その塗布量も精度良く一定量供給でき、もって溶接後端子表面にヌメリの発生しない、しかも製造が容易な蓄電池用端子の製造方法を提供することにある。   In view of the above problems, the object of the present invention is to accurately apply the flux only to the top of the terminal pole column, and also to supply a certain amount with a high accuracy, so that the surface of the terminal after welding does not cause slimming and is easy to manufacture. Another object of the present invention is to provide a method for manufacturing a storage battery terminal.

前記目的を達成すべく本発明の蓄電池用端子の製造方法は、電槽蓋に下端部を埋設した中空筒状のブッシング端子内に端子極柱を挿着し、かつ該端子極柱の頂部にのみ計量手段を介してノズルによりフラックスを載置した後、前記端子極柱と前記ブッシング端子とを溶接することを特徴とするものである。   In order to achieve the above object, a method for manufacturing a storage battery terminal according to the present invention includes inserting a terminal pole column into a hollow cylindrical bushing terminal having a bottom end embedded in a battery case lid, and placing the terminal pole column on the top of the terminal pole column. Only after the flux is placed by the nozzle through the measuring means, the terminal pole column and the bushing terminal are welded.

このようにしてなる本発明の蓄電池用端子の製造方法によれば、頂部が平坦な端子極柱へのフラックスの供給及び塗布を、バルブに装着された計量用の計量器による計量手段を介してノズルにより行うため、塗布する位置及び塗布量とも正確、かつ精度良く制御できる。 According to the storage battery terminal manufacturing method of the present invention thus configured, the supply and application of the flux to the terminal pole having a flat top portion are performed via the measuring means by the measuring meter attached to the valve. Since the nozzle is used, it is possible to accurately and accurately control the application position and the application amount.

それ故、フラックスを端子極柱の頂部にのみ供給、塗布でき、その量も精度良く制御できるので溶接に必要な量以上のフラックスを供給する恐れがなくなる。その結果、ブッシング端子と端子極柱の各頂部を溶接後、両者の頂部やブッシング端子の側面部、すなわち端子表面にヌメリが発生することがなくなる。   Therefore, the flux can be supplied and applied only to the top of the terminal pole, and the amount thereof can be controlled with high accuracy, so there is no possibility of supplying more flux than necessary for welding. As a result, after welding the bushing terminals and the tops of the terminal poles, no slimes are generated on the tops of the bushing terminals and the side surfaces of the bushing terminals, that is, the terminal surfaces.

しかも特許文献１に記載の発明のような事前の準備がほとんど必要でないため、製造も極めて容易になる。   Moreover, since there is almost no prior preparation as in the invention described in Patent Document 1, manufacturing is extremely easy.

本発明の蓄電池用端子の形成方法によれば、端子極柱頂部のみにフラックスを正確に載置でき、しかも精度良く一定量塗布できるので、製造した端子表面にヌメリのない、それ故、溶接後ヌメリを研磨する必要のない蓄電池用端子を、しかも容易に製造することができる。   According to the method for forming a storage battery terminal of the present invention, the flux can be accurately placed only on the top of the terminal pole column, and it can be applied with a certain amount with high accuracy. A storage battery terminal that does not need to be polished can be easily manufactured.

図１に本発明の蓄電池用端子の形成方法の一実施例を示す。
図１に示すように本発明の蓄電池用端子の製造方法は、まず電槽蓋１にその下端部を埋設した鉛合金製の、具体的には例えば、鉛―アンチモン合金製の中空筒状のブッシング端子２内に、これも鉛合金からなる端子極柱３を挿着し、かつ該端子極柱３の頂部にのみノズル７によりフラックスを一定量載置する。しかる後、前記端子極柱３と前記ブッシング端子２の各頂部同士をバーナー等の加熱手段で加熱して溶接するものである。 FIG. 1 shows an embodiment of a method for forming a storage battery terminal of the present invention.
As shown in FIG. 1, the method for manufacturing a storage battery terminal according to the present invention is made of a lead alloy having a lower end embedded in a battery case lid 1, specifically, for example, a hollow cylindrical shape made of lead-antimony alloy. A terminal pole 3 also made of a lead alloy is inserted into the bushing terminal 2, and a fixed amount of flux is placed by the nozzle 7 only on the top of the terminal pole 3. Thereafter, the tops of the terminal pole column 3 and the bushing terminal 2 are heated and heated by a heating means such as a burner.

図１において、符号８はフラックスを貯蔵するフラックスタンクを示し、符号９はバルブを示している。   In FIG. 1, the code | symbol 8 shows the flux tank which stores a flux, and the code | symbol 9 has shown the valve | bulb.

ところでこのバルブ９には計量用のシリンダー１０が装着されていて、例えばこのシリンダー１０を引くことで一定量のフラックスがフラックスタンク８側から吸引される。吸引された一定量のフラックスは、前記シリンダー１０を押すことでノズル７へと供給される。   By the way, a metering cylinder 10 is attached to the valve 9. By pulling the cylinder 10, for example, a certain amount of flux is sucked from the flux tank 8 side. A certain amount of sucked flux is supplied to the nozzle 7 by pushing the cylinder 10.

ノズル７の直下には、予め端子極柱３の頂部が位置決めされており、前述したように計量用のシリンダー１０により正確にその量が制御されたフラックスがノズル７より端子極柱３の頂部に滴下され、載置される。   The top of the terminal pole 3 is positioned immediately below the nozzle 7, and the flux whose amount is accurately controlled by the measuring cylinder 10 as described above is fed from the nozzle 7 to the top of the terminal pole 3. Dropped and placed.

図１において符号２０はこのようにして端子極柱３の頂部に載置されたフラックスを示して、その量は例えば０．１ｍｌである。なお端子極柱の頂部の径は例えば４．５ｍｍである。   In FIG. 1, reference numeral 20 indicates the flux placed on the top of the terminal pole 3 in this way, and the amount thereof is, for example, 0.1 ml. The diameter of the top of the terminal pole is 4.5 mm, for example.

このように一定量のフラックス２０を端子極柱３の頂部にのみ載置したら、通常行われているようにバーナー等の加熱手段でこれを加熱し、ブッシング端子２と端子極柱３の頂部を溶接して一体化し、前述した図３に示すような端子を形成した。   When a certain amount of flux 20 is placed only on the top of the terminal pole 3 in this way, it is heated by a heating means such as a burner as usual, and the bushing terminal 2 and the top of the terminal pole 3 are connected. By welding and integrating, a terminal as shown in FIG. 3 was formed.

溶接後製造した端子の表面、すなわちブッシング端子２と端子極柱３との溶接部及びブッシング端子２の側面を観測したが、従来問題になっていたヌメリは全く発生していなかった。   The surface of the terminal manufactured after welding, that is, the welded portion between the bushing terminal 2 and the terminal pole column 3 and the side surface of the bushing terminal 2 were observed.

さらに本発明の蓄電池用端子の製造方法の効果を確認すべく、本発明の方法で端子を１００個製造した。   Furthermore, in order to confirm the effect of the manufacturing method of the storage battery terminal of the present invention, 100 terminals were manufactured by the method of the present invention.

一方、これと比較するため予めスポンジにフラックスを含浸させておき、このスポンジを押し当てることにより端子極柱３の頂部にフラックスを塗布し、しかる後ブッシング端子２と端子極柱３の頂部をバーナーで加熱し、溶接して１００個の端子を製造した。   On the other hand, for comparison, a sponge is impregnated with flux in advance, and the sponge is pressed to apply the flux to the top of the terminal pole column 3, and then the bushing terminal 2 and the top of the terminal pole column 3 are burnered. 100 terminals were manufactured by heating and welding.

製造後の端子各１００個についてヌメリの発生を調べた。その結果、本発明の方法で製造した端子表面にはヌメリは全く見られず、１００個すべてについて問題がなかった。   The occurrence of slime was examined for each 100 terminals after manufacture. As a result, no slime was found on the surface of the terminal manufactured by the method of the present invention, and there was no problem for all 100 terminals.

しかしながら従来の方法で製造した１００個については、８５個について端子の表面にヌメリが発生していた。   However, about 100 pieces manufactured by the conventional method, the surface of the terminals of 85 pieces was slimmed.

以上のように、本発明の蓄電池用端子の製造方法によれば、従来のようにフラックスを含浸させた刷毛やスポンジに代えて、シリンダーの如き計量手段を介して、しかもノズルといった、いわゆる吐出口が細い供給手段によりフラックスを供給するため、端子極柱の頂部といった極めて狭い場所にも正確に、かつ一定量のフラックスを載置できる。それ故、製造した端子表面にヌメリの発生のない蓄電池用端子を製造することができる。   As described above, according to the method for manufacturing a storage battery terminal of the present invention, instead of a brush or sponge impregnated with flux as in the prior art, a so-called discharge port such as a nozzle is provided via a measuring means such as a cylinder. However, since the flux is supplied by a thin supply means, a certain amount of flux can be placed accurately and in a very narrow place such as the top of the terminal pole. Therefore, it is possible to manufacture a storage battery terminal in which no slime is generated on the manufactured terminal surface.

加えて溶接に先立ち、事前にブッシング端子２や端子極柱３に電極を接続する等の準備作業も必要でないため、製造も簡単である。   In addition, prior to welding, preparation work such as connecting electrodes to the bushing terminal 2 and the terminal pole column 3 in advance is not necessary, so that the manufacturing is easy.

ところで前記実施例において計量手段としてシリンダー１０を用いているが、計量手段としてはこのシリンダー１０に限定されるものではなく、フラックスのような液状体を計量できる計量器であれば他の計量器でも使用できる。   By the way, although the cylinder 10 is used as the measuring means in the embodiment, the measuring means is not limited to this cylinder 10, and any other measuring instrument can be used as long as it is a measuring instrument capable of measuring a liquid material such as flux. Can be used.

また同様に前記実施例ではシリンダー１０をバルブ９の位置に設置しているが、シリンダー１０はこの位置に限るものではなく、ノズル７の前であればどの位置に設けることもできる。   Similarly, in the above embodiment, the cylinder 10 is installed at the position of the valve 9, but the cylinder 10 is not limited to this position and can be installed at any position before the nozzle 7.
