DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soldering iron used for removing excess solder or scum adhered to a soldering iron or an oxide film formed on the iron. About tip cleaner.

[0002]

2. Description of the Related Art While using a soldering iron, frequent cleaning of the soldering iron is indispensable for performing good soldering. As shown in FIG. 7, a main part is provided with a pair of rotating shafts 1 and 2 which are rotated by a motor or the like at a specific position such as a base. Two foam rolls 3 having a flat surface without irregularities,
4 is fixed so that these peripheral surfaces are close to or in contact with each other.

[0003] When using this cleaner, two rolls 3 and 4 are impregnated with water by means of a spoiler and the like, and then these rolls 3 and 4 are rotated in the directions of arrows f1 and f2. The tip w is inserted between 3 and 4.

[0004]

In the conventional tip cleaner described above, when the tip w is inserted between the two foam rolls 3, 4, the rolls 3, 4 are inserted into the tip. When the tip w is pressed and elastically deformed,
Thus, the triangular gaps s, s as shown in FIG. 4 are formed. Therefore, the side portions of the tip w located at the gap places s, s are cleaned without contacting the peripheral surfaces of the rolls 3 and 4. It will not be.

Excess solder adhering to the upper and lower portions of the tip w is pushed by the peripheral surfaces of the foam rolls 3 and 4, moves on the surface of the tip w toward the side portions, and escapes to the gap. Therefore, it is not efficiently removed.

For this reason, in order to clean the entire periphery of the tip w, the tip w must be swung several times in the circumferential direction. The complexity is greatly reduced as compared to the processing by the work, but it still requires considerable effort and time.

Further, since the conventional processing still requires a considerable amount of time, the excess solder of the tip w is cooled by water contained in the rolls during the processing and solidifies, so that it cannot be removed. In order to remove such excess solder, the tip w must be once separated from the rolls 3 and 4 and heated again, and then the same cleaning process as described above must be performed again.

Further, as described above, the rolls 3 and 4 are made to contain an appropriate amount of water. However, if water is directly poured onto the peripheral surface of the rolls 3 and 4 during the rotation of the rolls 3 and 4, this causes Water is repelled by the centrifugal force generated by the rotation of the rolls 3 and 4 and is not efficiently absorbed by the rolls 3 and 4. For this reason, the rotation of the rolls 3 and 4 must be stopped each time the water supply process needs to be performed frequently when performing the above-described water supply process, which makes the operation cumbersome. I have.

It is an object of the present invention to provide a tip cleaner capable of solving the above-mentioned problems.
