Abstract

PURPOSE:To clean easily a soldering iron in a short time, by piercing the soldering iron into a slender band-like member which has heat resistance and elasticity, and is irregularly twined and continued. CONSTITUTION:When a soldering iron 1 to which molten solder 4 is adhering is pierced into a slender band-like member 6 contained in a vessel, the tip 1a of the soldering iron 1 goes into space since the slender band-like member 6 is irregularly twined and also continued, and the whole circumference of the soldering iron 1 is surrounded by the slender band-like member 6. In this state, when the soldering iron is made to execute a reciprocative motion upwards and downwards, the slender band-like member 6 scrapes off the molten solder 4 from the soldering iron 1 by its edge 6a. The scraped molten solder 4 is cooled by contacting with the slender band-like member 6, drops downwards gradually, is solidified, becomes powdery solder 4b, and collects in the bottom part of the vessel.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for cleaning a soldering iron, and in particular, it is possible to easily clean a soldering iron to which molten solder has adhered when used in irregularly intertwined strip-like members. The present invention relates to a method and apparatus for cleaning a soldering iron.

Conventionally, soldering irons conveniently used in electronic parts assembly factories, etc. have a copper core plated with nickel or iron, so the tip of the soldering iron oxidizes during use. Therefore, there is no need to use a file or the like to scrape the surface of the solder tip.

Therefore, conventionally, as shown in FIG.
I was cleaning it by pressing it against it. However, according to this method,
Although the sponge 3 is generally thin and porous, it exhibits considerable resistance to the piercing force of the solder tip.
It is impossible to clean the sponge 3 by piercing it with a soldering tip. For this reason, it is necessary to turn the soldering tool L sideways as shown in the figure, press only one side against the sponge 3, move it back and forth as shown by arrow A or B, and then rotate it as indicated by arrow C or D at F. It was not possible to remove the bath melted solder 4 adhering to the entire circumference of the soldering iron l. Therefore, cleaning the soldering iron 1 takes time, and the operator's hands tend to get tired due to the rotating operation of the soldering iron 1.

The surface and holes of the worn sponge 3 are clogged with solidified molten solder 4 and other impurities, and the sponge 3 becomes stained in a relatively short period of time.
It was uneconomical because the river could no longer be drained.

To apply additional pressure, the sponge 3 must be soaked in normal pressure water, so you have to be careful about replenishing the water, which is extremely troublesome. Manual soldering is a process step. The cleaning work of soldering irons has been a considerable obstacle in improving efficiency.

The present invention has been made to eliminate the drawbacks of the prior art described above, and its purpose is to easily pierce the soldering iron with molten solder and move it back and forth in the vertical direction. , and to clean the soldering iron in a short time. That is, instead of using a sponge that has been used in the past, a soldering iron is inserted into a heat-resistant and elastic thin strip member that is irregularly intertwined and connected, and the entire surface of the VC solder is simultaneously soldered to v'. This also eliminates the need to rotate the soldering iron during Shinsaki, thereby reducing the fatigue of the operator's hands. Another purpose is to cool the melted solder from the soldering iron with a thin strip-shaped member and let it fall from the soldering iron, thereby making it possible to use the cleaning device semi-permanently and repeatedly, thereby reducing costs. It is to aim for low sincerity. Another purpose is to facilitate maintenance of the cleaning device by reducing the use of water, and to improve the efficiency of the manual soldering process.

In other words, the method of the present invention is to pierce a solder tip with molten solder adhered to the continuous narrow band-like part of the irregular VC entanglement base having blood + Sa and elasticity into the material, and then apply it once. and peel off the melted material 111 at the edge of the narrow strip-shaped member,
This is a symptom of cleaning the soldering iron described in item 11 by solidifying the melted solder T while cooling it with a metal member and dropping it downward. Further, the device of the present invention includes a heat-resistant and elastic strip-shaped member that is irregularly intertwined and continuous, and a container that accommodates the strip-shaped member, and the container is open at the top and the narrow strip-shaped member is The IVi characteristic is that the soldering iron is exposed and the soldering iron with the melted solder force i attached to the thin strip-like member is pierced and reciprocated to clean the soldering iron.

The present invention will be explained below based on embodiments shown in the drawings. Broom 2
As shown in the figure, the mm soldering device 5 according to the present invention has heat resistance and elasticity L7, and continuous thin strips f16 intertwined irregularly are housed in a container 7, and the container 7 has an upper part. 7
a is opened and the thin strip-like member 6 is ejected, and the solder iron 1 is pierced and reciprocated to clean the soldering iron. It is composed of The strip V member 6 and [7] are preferably rust-free metal fly flakes with edges such as brass flakes or stainless steel flakes. Alternatively, a commercially available metal scrubbing brush for polishing the bottom of a pot or the like may be used.

The container 7 is preferably made of ceramic, crow, metal, heat-resistant plastic, etc., and the shape is not limited to cylindrical, but may be rectangular, etc.
It's okay.

The present invention is configured as described above. Fu・shi, 9 below, its effect e (I will explain about it.

In this state, by passing the soldering iron 1 to the FK, the thin strip-shaped member 6 is surrounded by the edge 6 of the iron, and the molten solder 4 is removed. Then, the stripped molten solder 4i1 is brought into contact with the narrow strip-shaped member 6, thereby attaching it to the narrow strip-shaped member VC while cooling the cooling field 11.
*xtc falls below l, solidifies [-7 and powdery solder 4
b, and the bottom 7bK of the container 7 accumulates as shown in FIG. The reason why the molten solder 4 is not applied to the thin strip-shaped member (for example, brass) during operation is that 7 lux has been removed from the I1w% VC of the semi-solid iron, and the thin strip-shaped member VC1 euflux is This is to prevent it from sticking.

In this way, the soldering iron 1 can be easily cleaned by simply sticking the soldering iron 1 into the narrow strip-shaped member 6 and moving it up and down, and no molten solder 4 is welded to the narrow strip-shaped member 6. Therefore, the thin strip member 6 can be used semi-permanently, and all you have to do is take out the strip member 6 from the container 7 from time to time and discard the powdery solder 4b that has accumulated on the bottom 7b. Cleaning is also extremely easy.

Since the present invention is configured and operates as described above, the soldering iron can be easily and quickly removed by simply sticking the soldering iron to which molten solder has adhered and moving it up and down. The effect of cleaning can be obtained. That is, instead of the conventionally used sponge, the entire surface of the soldering iron can be simultaneously soldered by piercing the soldering iron into a heat-resistant and elastic thin band-like member that is irregularly intertwined and continuous. It has the effect of being able to be cleaned. Further, as a result, there is no need to rotate the soldering iron during cleaning, which has the effect of reducing the fatigue of the operator's hands. Furthermore, since the molten solder removed from the solder tip can be cooled by the thin strip-shaped member and allowed to fall, it is possible to use the sweeping jet repeatedly semi-permanently, resulting in a low-cost machine. You can get the effect of bending. In addition, since the aluminum used for water is small, maintenance and management of the cleaning equipment becomes easier.
As a result, the semi-circle cutting technique developed by Chisaku was able to improve the efficiency of the process, making it an extremely useful invention for production lines.
