Problems solved by technology

[0010] But if carry out drag welding with existing jet soldering device, then because the surface tension of molten solder 2 is bigger, the molten solder 2 that may be attached to the soldering position is also drawn after the soldering position passes jet nozzle 6 tops. Pull, so that the excess molten solder 2 remains in the state of drooping on the soldered part
The excess molten solder 2 left in this way causes soldering failures such as the so-called "bridging phenomenon" and "icicle phenomenon".

Abstract

Provided is a jet soldering device with which it is possible to reduce problems associated with soldering such as bridging and protrusion formation. The disclosed jet soldering device is characterized by having: a solder bath (11) that stores melted solder; a jet nozzle (15) that comprises an end surface from which the melted solder is ejected, a cutout (30) provided in the aforementioned end surface, and a recovery wall (32) provided in the aforementioned end surface; a solder feeding mechanism (13, 20, 21, 22) that feeds the melted solder stored in the solder bath (11) to the jet nozzle (15); a tank driving mechanism (23, 24, 25, 26) that moves the solder bath (11); a solder receiving wall (42) that surrounds the jet nozzle (15) with a prescribed space therebetween and is connected to the jet nozzle (15); and a rotating mechanism (44, 45, 46) that transmits a drive force from the outside of the solder receiving wall (42) and rotates the solder receiving wall (42) and the adhesion nozzle (15).

Description

technical field [0001] The present invention relates to a jet brazing device and a brazing method for brazing a brazing component to a brazing object by bringing molten solder into local contact with the brazing object. Background technique [0002] Hereinafter, a conventional jet brazing device will be described with reference to the drawings. Figure 12 It is a figure which shows the outline of the structure of the conventional jet brazing apparatus. [0003] Such as Figure 12 As shown, the solder tank 1 contains molten solder 2 . The solder in the solder tank 1 can be melted by heating the solder tank 1 . Moreover, by controlling the temperature at which the solder tank 1 is heated, the molten solder 2 in the solder tank 1 can be kept at a constant temperature. [0004] A propeller 3 and a solder supply path 4 are provided in the solder tank 1 . The propeller 3 is arranged at one end of the solder supply path 4 . The molten solder 2 is pressure-fed inside the solder ...
