[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soldering device used, for example, when mounting electronic components on a circuit board or the like.

0002

[Prior Art] In conventional soldering work using a soldering iron, the tip of the soldering iron is pressed against a board and heated by thermal conduction to melt the solder between the board and the electronic component.
After that, the soldering iron tip is separated and the soldered part is allowed to cool naturally, thereby joining the two.

0003

[Problems to be Solved by the Invention] Conventional soldering irons do not pose much of a problem when soldering parts to be joined with a small heat capacity, but for example, when soldering parts to be joined that have a small heat capacity, it is difficult to solder parts such as circuit boards containing planes or thick metal plates. When soldering components to a board with a large heat capacity, there is a problem in that heating and cooling take time and are inefficient.

The present invention has been made based on the above circumstances, and an object of the present invention is to provide a soldering device that can efficiently heat and cool parts to be joined.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a soldering apparatus that performs soldering by contacting and heating a soldering iron tip with a part to be joined, in which an atmosphere is applied to the soldering iron tip. The present invention is characterized in that a blower means for sending out gas is provided, and a heat generating means for generating heat to melt the solder is provided in the blower means or its ventilation path.

[0006] Preferably, the atmospheric gas is an inert gas.

[0007]

[Operation] With the above-described structure, the present invention presses the soldering iron tip against the part to be welded and heats it, and at the same time blows atmospheric gas heated by the blowing means or the heating means provided in the ventilation path onto the soldering iron tip. Perform auxiliary heating. After soldering is completed, the tip of the soldering iron is removed from the part to be joined, the heat generating means stops generating heat, and only air is blown, thereby promoting heat dissipation from the soldered part. Thereby, the time required for heating and cooling can be shortened.

[0008] By using an inert gas as the atmospheric gas, oxidation of the solder can be prevented.

Further, in the vicinity of the air outlet 24 of the ventilation path 26, a heat generating section 30 made of an electric heater is provided. Although not shown, the grip part 14 of the soldering iron part 10 has a heat generating part 3 at a position where it is easy to work.
0 switch and a ventilation valve to start and stop ventilation.

When using the apparatus of this embodiment, first, the soldering part of the board is heated by pressing the soldering iron tip 12 against the board, etc. At the same time, the heat generating part 30 is energized to blow hot air onto the soldering part. This assists the temperature increase by the soldering iron tip 12. After soldering, the soldering iron tip 12 is separated from the board, the heat generating part 30 is turned off, and only air is blown.
Blow cold air onto the soldered area to promote heat dissipation from the soldered area.

As described above, according to the apparatus of this embodiment, in addition to heating the soldering part by heat conduction from the tip of the soldering iron, the temperature of the soldering part can be increased by blowing hot air from the blower. Furthermore, by blowing cold air during cooling, heat dissipation from the soldered parts can be promoted, reducing work time.

Needless to say, the air blower 01 and 202 have a built-in heat generating part like the blower 20.

Further, in the above embodiment, the case where air is used as the atmospheric gas has been described, but an inert gas such as nitrogen gas or helium gas may also be used as the atmospheric gas. This can prevent solder from oxidizing.
