However, the conventional soldering iron cleaner as described above has the following problems.
Soldering iron cleaners with a sponge containing water can remove excess solder, but flux such as pine resin used for soldering remains on the sponge surface and carbonizes by reattaching to the cleaned tip. There was a problem that the wettability deteriorated due to sticking to the tip.
In the technique described in Patent Document 1, although the excess solder is easy to wipe because it has a wiper portion equipped with a capture chip, the outer periphery of the soldering iron is uniformly wiped with the capture chip in order to remove the flux adhering to the tip. This is what you need. Therefore, there is a problem that the flux cannot be wiped efficiently. Further, when the tip is wiped with the capture tip, there is a problem that the solder coating portion provided at the tip of the tip is easily damaged or peeled off.
In recent years, in order to prevent diffusion of lead (Pb), which is a harmful metal, into the natural environment, instead of conventional lead-tin eutectic solder, a tin (Sn) -based low melting point alloy that does not use lead, so-called lead-free Increasing use of solder. Since lead-free solder has a high melting point, it is easy to set the tip temperature high, and therefore, the carbonization of the flux on the tip is likely to proceed.
Therefore, the techniques described in the related art and Patent Document 1 have problems that workability is deteriorated when lead-free solder is used, and high-quality soldering cannot be performed.

  The present invention has been made in view of the above problems, and a soldering iron cleaner capable of easily and reliably removing surplus solder and surface deposits such as flux from a soldering iron tip, and An object is to provide a soldering iron stand.

The configuration is such that it can be made.
According to this invention, the tip of the soldering iron is inserted between the heat-resistant brushes and moved in the width direction of the brush, so that each brush tip of the brush comes into contact from the side of the tip. Therefore, excess solder and flux adhering to the tip can be easily removed. Also, since the brush hits the tip, the tip surface is cleaned by the contact of a large number of brush tips, and the flexibility of the tip such as the solder plating part does not damage the tip. Can be cleaned.

According to a second aspect of the present invention, in the soldering iron cleaner according to the first aspect, the width direction of the brush is set to a substantially horizontal direction, and the facing distance between the brush tips gradually increases from vertically downward to vertically upward. The configuration is expanded to
According to the present invention, the brush tip comes into contact with the side surface of the tip substantially uniformly by inserting the soldering iron whose diameter is reduced toward the tip from the vertical direction and moving it in a substantially horizontal direction. Therefore, the tip can be cleaned efficiently.

According to a third aspect of the present invention, in the soldering iron cleaner according to the first or second aspect, the tip can be protruded along the facing position of the brush tip on the side in the thickness direction of the brush. In addition, a relief space is formed in which cleaning waste can be discharged.

FIG. 2A is an explanatory plan view for explaining the soldering iron cleaner according to the embodiment of the present invention. FIG.2 (b) is AA sectional drawing in Fig.2 (a). FIG. 2C is an explanatory diagram of the back surface as viewed in B in FIG.

A soldering iron cleaner and a soldering iron table according to an embodiment of the present invention will be described.
As shown in FIG. 1, the schematic configuration of the soldering iron table 1 of the present embodiment includes a soldering iron holder 4 and a cleaner housing part 9 provided on a base 8, and the cleaner housing part 9 has A sponge 3 and a soldering iron cleaner 2 are provided.
The soldering iron holder 4 is for holding and holding a heating part of a soldering iron (not shown), an opening 4a for inserting the soldering iron, and a guide part 4b for holding the heating part of the soldering iron, Is provided. And the arm 6 provided in the lower surface of the soldering iron holder 4 is engaged with the hinge part 7 standingly arranged on the base 8 so that rotation is possible. For this reason, the soldering iron holder 4 is configured to be able to change the inclination angle with respect to the installation plane of the base 8.
The cleaner storage unit 9 is a box-shaped container having a substantially rectangular shape in plan view with an opening on the upper side, and a partition plate 9a is provided upright at the center.
The sponge 3 is for separating excess solder from the tip by wiping the tip of the soldering iron with water, and is one side of the space partitioned by the partition plate 9a of the cleaner storage portion 9. It is stored in.
The soldering iron cleaner 2 is disposed in the other space partitioned by the partition plate 9a.

The soldering iron cleaner 2 according to this embodiment will be described.
The schematic configuration of the soldering iron cleaner 2 is on a plane extending in the horizontal direction of a support base 2a (see FIG. 2B) having a substantially rectangular shape in plan view (see FIG. 2A) and a substantially U-shaped cross section. The cleaning brushes 20 and 20 (brushes) are arranged to face each other.
The cleaning brush 20 is for scraping off surplus solder, flux, and surface deposits such as oxides and carbides attached to the surface of the heated tip from the surface, and is in contact with the heated tip. A number of brush bristles 20a made of a heat-resistant material that does not deteriorate, for example, a thin metal wire or metal wire, are aligned to a predetermined length and width, and the ends are pressed by the brush holder 20b, and the fixing screw 11 ... Is fixed to the support base 2a. That is, in the cross section in the direction orthogonal to the width direction (the thickness direction of the brush) (the cross section in the direction along the line AA in FIG. 2A), the brush bristles 20a open around the brush holder 20b, and the brush tip The envelope of 20A has a substantially fan shape.

As for the arrangement postures of the cleaning brushes 20 and 20, both sides of the substantially fan-shaped and the brush holder 20b are brought into contact with the support base 2a. The cross-sectional shape of the brush facing portion 10 is, as shown in FIG. 2 (b), the brush tips 20A, 20A that form a substantially fan-shaped arc portion, which are substantially in contact with each other on the lower side and open upward. It is made into a shape. That is, when the tip having a diameter reduced in the tip direction is inserted into the brush facing portion 10, a valley shape is formed so that the brush tip 20 </ b> A can come into contact with both the left and right sides of the tip.
The shape related to the brush tip 20 </ b> A, such as a substantially sector shape or a valley shape, represents the approximate shape. Therefore, the brush tips 20A, 20A being substantially in contact means that the virtual envelope surface formed by the tips of the plurality of brush tips 20A is substantially in contact, and the tips of the individual brush tips 20A are In the facing direction, they overlap each other or are slightly apart.

The material of the brush bristles 20a is, for example, when using a metal wire or metal wire, although it depends on the material and shape, the wire diameter is preferably about 0.1 mm to 0.5 mm, brass alloy (brass), stainless steel, and surface treated. Materials such as steel can be used. In particular, a material that is difficult to be soldered is preferable so that the solder coating layer of the tip is not lost. As a suitable example of the brush bristles 20a, a stainless steel wire having a wire diameter of about 0.2 mm can be employed.
Moreover, as long as it is a material suitable for cleaning the tip, it is not limited to metal, and may be heat-resistant synthetic resin, or a metal wire may be coated with heat-resistant synthetic resin, or metal wire and resin wire may be coated. It may be a twisted wire.
The shape of the brush bristles 20a is not limited to a straight wire, and may be a shape that is finely bent into a corrugated shape or a mountain shape so that the surface deposits can be easily scratched when abutting between the tip and the abdomen. .

On the other hand, the support 2a is provided with a slot 2c in the vicinity of the brush facing portion 10 along the direction in which the brush facing portion 10 extends (see FIG. 2C). The slot 2c extends over the entire length or most of the width direction of the brush facing portion 10.
The width of the slot 2c is such that at least the tip of the tip does not easily contact the hole end of the slot 2c when the tip of the soldering iron is inserted from above the brush facing portion 10. .
Since the support base 2a has a U-shaped cross section, cleaning waste falls along the brush facing portion 10 or the tip 12a protrudes between the slot 2c and the bottom of the cleaner housing portion 9. Can be. Accordingly, the groove 2c and the space 13 form a clearance space for the cleaning waste and the tip 12a.

The operation of the soldering iron cleaner 2 according to this embodiment will be described.
FIG. 3A is a perspective explanatory view for explaining a tip cleaning operation using the soldering iron cleaner according to the embodiment of the present invention. FIG.3 (b) is side explanatory drawing of the C view in Fig.3 (a).
In order to clean the tip 12a of the soldering iron 12, the soldering iron 12 is held in a posture that obliquely intersects a horizontal plane similar to that for soldering, and the brush facing portion of the soldering iron cleaner 2 is used. 10, the tip 12 a is inserted and reciprocated as many times as necessary in the width direction of the cleaning brush 20 where the brush facing portion 10 extends.
Then, as shown in FIG.3 (b), during this reciprocation, many brush tips 20A and 20A contact | abut on the tip 12a from the left and right sides. Therefore, the entire surface of the tip 12a is rubbed by the bristle tip strength and elasticity of the brush tip 20A, and excess solder, flux, oxides and carbides thereof, etc. attached to the surface are scraped off.

At that time, due to the flexibility and elasticity of the brush tip 20A, the original tip 12a or the minimum necessary solder coating layer is not scraped off. There is an advantage that there is no fear of damaging the tip 12a and the solder coating layer.
Also, in the conventional soldering iron cleaner, a member that scrapes off deposits from one side comes into contact with the surface, so that the cleaning waste scraped off on the contacting side goes around to the opposite side of the iron tip. Although there was a case where it could not be removed from the tip, according to the present embodiment, the cleaning waste that wraps around to the opposite side is scraped by the brush tip 20A on the opposite side, so that there is an advantage that the cleaning waste can be surely scraped off. .

  The cleaning waste peeled off from the tip 12a finally falls to the lower part of the support base 2a through the slot 2c and is discharged out of the brush bristles 20a. In this embodiment, since the soldering iron cleaner 2 is detachable from the cleaner housing portion 9, there is an advantage that cleaning waste accumulated at the bottom of the cleaner housing portion 9 can be appropriately discharged.

In this embodiment, since the flexible cleaning brush 20 is used, the angle of the soldering iron 12 is changed according to the size of the tip 12a, the amount of surface deposits, and the like. By rotating in the direction or changing the depth of insertion of the tip 12a, the brush bristles 20a are uniformly contacted with the surface of the tip 12a, or the amount of contact with the brush tip 20A is adjusted, More efficient cleaning can be performed.
At that time, since a clearance space is formed in the vicinity of the side of the brush facing portion 10, it is possible to prevent the tip 12a from being accidentally brought into contact with the support base 2a and the cleaner storage portion 9 to be damaged. it can.

As described above, according to the cleaning brush 20 of the present embodiment, a simple operation of reciprocating between the cleaning brushes 20 while maintaining a holding posture substantially the same as the soldering operation in which the soldering iron is set at an appropriate angle with respect to the horizontal surface. Further, surface deposits such as excess solder and flux can be easily and reliably removed from the tip of the soldering iron without accidentally damaging the tip. As a result, the surface of the tip can always be kept clean during the soldering operation, so that a high-quality soldering operation can be performed efficiently.
In this embodiment, in particular, the flux is often used in an increased amount, and the soldering operation using the lead-free solder, which requires the tip temperature to be relatively high, is performed while easily removing the flux. You can continue working. Therefore, there is an advantage that high-quality soldering work using lead-free solder can be performed.

Moreover, according to the soldering iron table 1 of this embodiment, by providing the cleaning brush 20, it is possible to provide an apparatus that has the same operational effects as described above and can easily discharge and remove cleaning waste. .
Further, since the cleaning brush 20 can be arranged in parallel with the sponge 3 containing water, the flux that tends to adhere to the tip 12a after the excess solder is dropped with the sponge 3 is immediately scraped off by the cleaning brush 20. Can be very convenient.

  In the above description, the soldering iron cleaner is described as having a set of brushes, but a plurality of sets may be provided. In that case, the material, flocking density, shape, etc. of the brush can be changed for each group. If it does so, there exists an advantage which can be set as the soldering iron cleaner which changed the cleaning degree in steps, such as rough cleaning and finishing cleaning, for example. Moreover, there is an advantage that a soldering iron cleaner that can be suitably used even when the degree of adhesion of surface deposits and the shape of the tip to be cleaned is different.

In the above description, the brush has been described as an example in which the width direction is set in a substantially horizontal direction. For example, the width direction is inclined so that the soldering iron can be moved in an operator's preferred posture. May be arranged. In that case, you may arrange | position the support stand 2a itself inclining, for example.
Further, in the above description, the escape space is described as an example including the slot 2c and the space 13 in the vicinity thereof. However, if the member is not disposed near the side of the brush facing portion 10, the slot is not necessarily provided. 2c may not be provided. For example, the structure etc. which divided | segmented the plane part of the support stand 2a into two, and formed the slit between them may be sufficient.

It is a perspective view for demonstrating the soldering iron stand which concerns on embodiment of this invention. It is a plane explanatory view for explaining a soldering iron cleaner concerning an embodiment of the present invention, an AA sectional view, and a back side explanatory view.
