Abstract

PURPOSE:To always feed a string solder at a fixed position for a soldering iron tip even if the upper and lower positions of a soldering substrate vary, by performing the positioning of a solder supporting part by the stopper in the space with a soldering iron tip supporting part and fixing the relative position of the both supporting parts. CONSTITUTION:With the actuation of an air cylinder 3 a soldering iron tip and solder supporting parts 11, 10 are descended symmetrically by being pushed down with springs 18, 19 and a string solder 2 is pinched between the soldering iron tip 1 and a pad lead 4. The soldering iron tip 1 is lifted by a spring 5 just before its abutting the lead 4 and finally positioned by the stopper 6, which is adjusted so that the soldering iron tip 1 and solder 2 may become an optimum positional relation in advance and the positional relation of the both is always made constant. The supporting parts 11, 10 are pressed via springs 18, 19 by the cylinder 3 and when the soldering iron tip 1 is abutted to a substrate 14 before the stroke end of the cylinder 3, the springs 18, 19 are contracted and the soldering iron tip stops at that time. The soldering iron tip is therefore following up the substrate 14 at all times even if the soldering position moves up and down by the deflection of the substrate 14, etc. and the solder 2 follows the soldering iron tip as well, so it becomes feedable to the constant position always.

[Prior Art] As shown in FIGS. 3 and 4, in the conventional device, a soldering iron tip supporting portion 11 having a soldering iron tip 1 attached to a slide rail 7 is attached to a slider 9 and slides up and down. A solder support part 10 supporting a solder feed tube 13 that feeds the solder thread 2 is also attached to the slider 8 and slides up and down. Solder tip support part 11 and solder support part 1
0 is held by an air cylinder 3 and fixed by a spring. As shown in Fig. 3, before soldering, the solder wire 2 is positioned below the iron tip.
When soldering, the solder is inserted between the iron tip 1 and the pad lead 4, and the solder is used as solder to efficiently preheat.

During actual soldering, use the air cylinder 3 as shown in Figure 4.
As a result, the tip of the soldering iron and the solder wire descend in the positional relationship shown in FIG. The part 10 is lifted and the solder wire 2 is lifted to the optimum position for supplying solder to the pad bond 4. This is intended to improve the soldering success rate by controlling the incoming solder and the actual solder supply point.

The above purpose is not to position the soldering support part 10 by a fixed positioning stopper 17 fixed to the slide rail 7, but to provide a positioning stopper between the soldering support part 11 and the soldering iron tip support part 11. This is achieved by fixing the relative position with the support part 10.
