[Detailed description of the device]

[0001]

[Industrial application]

 This invention relates to a soldering iron.

[0002]

[Prior Art]

 FIG. 4 is a diagram showing an example of a conventional soldering iron. This soldering iron is of a so-called piston type and has a solder supply mechanism.

Reference numeral 1 is a substantially T-shaped case, and the case 1 includes a grip portion 1a and an upper side portion 1b. A so-called grip type switch 2 is arranged above the grip portion 1a. The switch 2 operates the solder supply device. Reference numeral 3 denotes a soldering iron chip, and a tip portion 3a of the soldering iron chip 3 is curved downward. A heater (not shown) is internally provided in the soldering chip 3.

Reference numeral 4 denotes a solder guide pipe (hereinafter, referred to as “pipe”) that constitutes a solder supply mechanism, and a delivery port 4 a of the pipe 4 faces the tip portion 3 a. Then, the solder wire 5 is supplied from the delivery port 4a of the pipe 4 toward the tip portion 3a. In other words, in this soldering iron, the solder wire 5 is supplied to the tip portion 3a in an arbitrary amount by appropriately operating the switch 2. Then, soldering is performed.

[0005]

[Problems to be solved by the device]

 By the way, in the soldering iron shown in FIG. 4, carbonized residue (dust) of the flux or extra solder is attached to the tip portion 3a during the soldering. Therefore, in order to perform proper soldering, it is necessary to remove dust and the like from the tip portion 3a. Therefore, the tip portion 3a to which the dust and the like is attached is rubbed onto a cleaner (sponge containing water) 6 as shown in FIG. 4 to remove the dust and the like.

However, in this case, the scraps and the like cannot be removed unless the tip portion 3a is rubbed to the cleaner 6, and the soldering work cannot be performed smoothly and quickly. In particular, since the tip portion 3a is rubbed onto the cleaner 6, the temperature of the tip portion 3a is lowered, which may hinder the subsequent soldering work.

Therefore, an object of the present invention is to smoothly and swiftly remove scraps and the like to improve the soldering work.

[0008]

[Means for Solving the Problems]

 In this invention, the air pipe outlet is arranged so as to face the tip of the soldering iron chip. Further, when heating the air pipe, a part of the air pipe is installed inside the heater cover of the soldering iron chip so that the heat of the heater for heating the soldering iron chip is conducted to the air pipe.

[0009]

[Action]

 During the soldering, compressed air is discharged from the blowout port 10a of the air pipe 10 to the tip portion 3a of the soldering iron. The compressed air blows off carbonized residue 15 of the flux attached to the tip portion 3a and excess solder from the tip portion 3a. That is, the dust 15 and the like are removed from the tip a. Therefore, the tip 3a of the soldering iron does not have to be rubbed on the cleaner to remove the scraps 15 and the like, and the scraps 15 and the like can be removed smoothly and quickly, and the soldering work can be favorably performed. ..

Further, when the air pipe 10 is heated, compressed air is discharged as hot air from the air outlet 10a of the air pipe 10, so that dust and the like can be removed without lowering the temperature of the tip portion 3a more than necessary. The subsequent soldering work can be performed better. Particularly when the air pipe 10 is provided inside the heater cover 8 of the soldering iron chip 3, the heat of the heater 9 can be effectively used.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. In these figures, the portions corresponding to those in FIG. 4 are designated by the same reference numerals, and detailed description thereof will be omitted.

A heater cover 8 is attached to one end of the upper side portion 1b. The heater cover 8 projects from the case 1. As shown in FIG. 2, the soldering iron chip 3 and the air pipe 10 are attached to the heater cover 8. The air pipe 10 is bent and formed so that its tip corresponds to the tip 3 a of the soldering iron chip 3. The outlet 10a of the air pipe 10 faces the tip 3a of the soldering iron chip 3 that faces the outlet 4a of the pipe 4. An air compressor (not shown) is connected to the base end of the air pipe 10.

As shown in FIG. 2, the soldering iron chip 3 is internally provided with a heater 9. The heater 9 heats the soldering iron chip 3. The heater 9 is connected to a commercial power source via a transformer (not shown). As shown in FIG. 1, the case 1 is provided with a switch 11 above the switch 2 for opening and closing an air valve (not shown).

First, for soldering, a plug (not shown) is connected to an outlet to heat the heater 9. Then, after the tip portion 3a reaches an arbitrary temperature, the switch 2 is operated to send the thread solder 5 to the tip portion 3a (see FIG. 1). When the solder wire 5 comes into contact with the tip portion 3a, the solder wire 5 melts, so that soldering is performed.

Next, in order to remove the carbonized residue 15 of the flux from the tip portion 3a during the soldering, the switch 11 is pressed and compressed air is blown to the tip portion 3a from the air outlet 10a of the air pipe 10. The dust 15 is discharged to blow away the dust 15. As a result, as shown in FIG. 2, the dust 15 is removed from the tip portion 3a. Further, as shown in FIG. 2, since a part of the air pipe 10 is arranged in the same heater cover 8 as the soldering iron chip 3, the air pipe 10 is heated and passes through the air pipe 10. The compressed air is also heated. Therefore, the compressed air discharged from the air outlet 10a of the air pipe 10 becomes hot air, and the dust 15 is removed without lowering the temperature of the tip 3a more than necessary.

According to this example, the dust 15 or the like attached to the tip portion 3a of the soldering iron chip 3 is blown off from the tip portion 3a by the compressed air discharged from the air outlet 10a of the air pipe 10. The portion 3a does not have to be rubbed on the cleaner, and the glass 15 and the like can be removed smoothly and quickly, and the soldering work can be performed well. Further, according to this example, since compressed air is discharged as hot air from the air outlet 10 of the air pipe 10, the dust 15 and the like can be removed without lowering the temperature of the tip portion 3a of the soldering iron chip 3 more than necessary. The soldering work can be performed better. Particularly, since a part of the air pipe 10 is provided inside the heater cover 8, the heat of the heater 9 can be effectively used.

Further, according to the present example, since the blowout port 10a of the air pipe 10 is opposed to the portion of the tip 3a of the soldering iron chip 3 facing the delivery port 4a of the pipe 4, the dust 15 and the like can be removed. You can do better.

FIG. 3 shows another embodiment of the present invention. This example is a so-called stick soldering iron, and the soldering iron chip 3 has a linear shape. Therefore, in this example, only the tip of the air pipe 10 is bent toward the tip 3a. In this example, a solder supply mechanism for supplying solder to the tip 3a of the soldering iron chip 3 is not provided. Other configurations and operational effects are similar to those of the above-described embodiment.

In each of the above-described embodiments, the solder code chip 3 and the air pipe 10 are both provided inside the heater cover 8, but the air pipe 10 may be arranged outside the heater cover 8. .. However, in this case, the heat of the heater 9 cannot be used.

Further, the present invention can be similarly applied to soldering irons other than the above-mentioned embodiments regardless of their shapes. The point is that the tip of the soldering iron chip is made to face the air outlet of the air pipe to blow off dust and the like.

[0021]

[Effect of the device]

 According to this invention, the air outlet of the air pipe is arranged so as to face the tip of the soldering iron chip. Therefore, the carbonized residue of the flux attached to the tip by the compressed air discharged from the outlet is removed from the tip. It can be blown off, scraps and the like can be removed smoothly and quickly, and soldering work can be improved.

Further, when the air pipe is heated, it is possible to remove dust and the like without lowering the temperature of the tip portion of the soldering iron chip more than necessary, and to perform the subsequent soldering work better. Particularly when the air pipe is installed inside the heater cover of the soldering iron chip, the heat of the heater can be effectively used.
