【従来の技術】[Prior art]

OA機器や家庭電気製品には多数のリード線が配線され、また近年は自動車に もそのエレクトロニクス化に伴い多数のリード線が配線されている。これらのリ ード線は回路基板への実装時には予め半田が付着される。 A large number of lead wires are wired in office automation equipment and home electric appliances, and in recent years, a large number of lead wires are also wired in automobiles due to the shift to electronics. Solder is attached to these lead wires in advance when they are mounted on the circuit board.

【0003】 図4は従来の半田付着装置を示したもので、溶融半田1を収容する半田槽2に は、溶融半田の循環路の一部を形成する半田吐出パイプ3が内蔵されている。こ の半田吐出パイプ3には半田循環用のファン4が設置され、このファン4はモー タ5によって回転駆動される。ファン4の回転によって、溶融半田1は矢印で示 されたように、半田吐出パイプ3内に流入しそこを上昇流動して、半田吐出パイ プ3の上端開口から流れ落ちる。こうして、半田槽2内の溶融半田1はファン4 によって半田吐出パイプ3を通って循環される。FIG. 4 shows a conventional solder depositing apparatus, in which a solder bath 2 for containing the molten solder 1 contains a solder discharge pipe 3 forming a part of a circulation path for the molten solder. A fan 4 for solder circulation is installed on the solder discharge pipe 3, and the fan 4 is rotationally driven by a motor 5. By the rotation of the fan 4, the molten solder 1 flows into the solder discharge pipe 3 and flows upward as shown by the arrow, and then flows down from the upper end opening of the solder discharge pipe 3. Thus, the molten solder 1 in the solder bath 2 is circulated through the solder discharge pipe 3 by the fan 4.

【0004】 電線6は先端部の被覆が取り除かれ、露出した線材7にはフラックスが塗布さ れている。電気部品把持具8はこの電線6を把持した状態で矢印のように旋回さ れる。この旋回によって、線材7は半田吐出パイプ3の上端開口から吐出される 溶融半田の吐出上面1Aに浸漬され、溶融半田が付着する。電気部品把持具8の 旋回は、浸漬される線材7の長さ及び浸漬時間が正確に制御されるように行われ 、これによって、線材7への半田の付着量が常に一定となる。The electric wire 6 is stripped of the coating at the tip, and the exposed wire 7 is coated with flux. The electric component gripper 8 is swung as shown by the arrow while gripping the electric wire 6. By this turning, the wire rod 7 is immersed in the molten solder discharge upper surface 1A discharged from the upper end opening of the solder discharge pipe 3, and the molten solder adheres thereto. The swiveling of the electric component gripping tool 8 is performed so that the length of the wire 7 to be dipped and the dipping time are accurately controlled, so that the amount of solder adhered to the wire 7 is always constant.

【考案が解決しようとする課題】[Problems to be solved by the device]

ところが、上述の従来の半田付着装置は、溶融半田が空気と接触することによ って溶融半田の表面に薄い酸化皮膜が形成され、この半田の酸化皮膜によって線 材への半田の付着量が一定にならず、バラツキが生じてしまうといった問題が存 在する。 そこで、本考案の目的は、半田の酸化膜を除去して、電気部品への溶融半田の 付着量を一定にすることができる半田酸化膜除去装置を提供することである。 However, in the above-described conventional solder attaching apparatus, when the molten solder comes into contact with air, a thin oxide film is formed on the surface of the molten solder, and the oxide film of the solder increases the amount of the solder attached to the wire. There is a problem that it is not constant and there are variations. Therefore, an object of the present invention is to provide a solder oxide film removing device capable of removing the oxide film of the solder and making the amount of the molten solder adhered to the electric component constant.

There is. Thus, the scraper 12 is connected to the air cylinder output shaft 9a by the connecting member 11 so as to extend in the direction perpendicular to the moving direction of the air cylinder output shaft 9a. The scraper 12 is in contact with the discharge surface 1A of the molten solder discharged from the upper end opening of the solder discharge pipe 3.

【0010】 次に、この実施例の作用を説明する。 電気部品把持具8によって把持された電線6は、予め先端部の被覆が取り除か れ、露出した線材7にはフラックスが塗布されている。エアシリンダ9は図示を 省略した制御装置からの信号に応じて起動され、出力軸9aを駆動して連結部材 11を介してスクレーパー12を図1に矢印で示したように一方向に所定距離だ け水平移動させる。こうして、スクレーパー12は、溶融半田の吐出面1Aの内 の所定領域1aを移動し、このスクレーパー12の所定距離の水平移動によって 、所定領域1aに形成されている半田の酸化膜が除去される。Next, the operation of this embodiment will be described. The electric wire 6 gripped by the electric component gripping tool 8 has the coating of the tip portion removed in advance, and flux is applied to the exposed wire rod 7.

Therefore, the wire 7 of the electric wire 6 is always immersed in the molten solder from which the oxide film of the solder has been removed, so that the amount of the molten solder adhered to the wire 7 is always constant. In the above embodiments, the molten solder is attached to the electric wire 6, but the present invention is not limited to this, and can be applied to the case where the molten solder is attached to any electric component other than the electric wire.
