Abstract

For cleaning hot soldering iron bits which are contaminated or soiled by tin oxides and soldering residues a flat felt or sponge has often been heretofore used. This cleaning technique is impractical, incomplete and frequently causes spatters of soldering tin or pewter at the place of work. This is unacceptable, especially when precision soldering electronic devices. This problem is solved by using an apparatus driven by an electric motor. The hot soldering iron bit or tip is momentarily placed between two cleaning bodies which rotate towards each other. These two rotating cleaning bodies thus enclose the soldering iron bit and protectively clean the same. The cleaning bodies are mounted in a removable holder or cage provided with a tin collection container or receptacle. For enhancing the self-cleaning action of the two cleaning bodies the spacing between the axes or shafts of the two cleaning bodies is smaller than the mean diameter of both cleaning bodies. Additionally, two strippers or scrapers engage into each cleaning body.

Claims

1. An apparatus for mechanically cleaning hot soldering iron bits contaminated with contaminants, such as tin oxides and soldering residues, comprising:

at least two cooperating oppositely situated, counter-rotating cleaning bodies for cleaning a soldering iron bit of contaminants;

each of said cleaning bodies having a lengthwise extending axis;

means for mounting said two cleaning bodies such that the distance between said lengthwise extending axes is less than the mean diameter of said cleaning bodies, so that said cleaning bodies are continuously in mutual contact with one another at least at portions of their circumference; and

means for rotatably driving said counter-rotating cleaning bodies at different rotational speeds, whereby said mutually contacting portions of said cleaning bodies exert a kneading action upon one another and thus a self-cleaning action upon one another, to thereby ensure that during cleaning of a contaminated soldering iron bit essentially only non-contaminated portions of said counter-rotating cleaning bodies come into contact with said contaminated soldering iron bit.

2. The apparatus as defined in claim 1, wherein:

said two cleaning bodies are arranged such that said lengthwise extending axes thereof extend substantially axially parallel to each other; and

each of said two cleaning bodies being arranged upon a related entrainment shaft.

3. The apparatus as defined in claim 1, wherein:

said rotatably driving means comprise electrical drive means for driving said two cleaning bodies.

4. The apparatus as defined in claim 3, wherein:

said electrical drive means comprises an individual drive for each of said two cleaning bodies.

5. The apparatus as defined in claim 1, wherein:

said each of said two cleaning bodies possess a substantially brush-like surface.

6. The apparatus as defined in claim 1, wherein:

said two cleaning bodies possess a substantially porous surface.

7. The apparatus as defined in claim 5 or 6, wherein:

said two cleaning bodies are formed of a synthetic material of high molecular weight.

8. The apparatus as defined in claim 7, wherein:

said synthetic material is polytetrafluoroethylene.

9. The apparatus as defined in claim 7, wherein:

said synthetic material is a chlorinated rubber.

10. The apparatus as defined in claim 5 or 6, wherein:

said cleaning bodies contain a natural organic substance.

11. The apparatus as defined in claim 10, wherein:

said natural organic substance is a sponge.

12. The apparatus as defined in claim 10, wherein:

said natural organic substance is linen.

13. The apparatus as defined in claim 1, further including:

a housing within which there are mounted said cleaning bodies; and

a tin collecting device provided for said housing.

14. The apparatus as defined in claim 13, wherein:

said housing includes means enabling said housing to be selectively opened and closed.

15. The apparatus as defined in claim 13, wherein:

said mounting means includes a removable cage member for mounting said cleaning bodies.

16. An apparatus for mechanically cleaning hot soldering iron bits contaminated with contaminants, such as tin oxides and soldering residues, comprising:

at least two oppositely situated, interacting counter-rotating cleaning bodies formed of a sponge-like material for cleaning a soldering iron bit of contaminants;

each of said sponge-like cleaning bodies having a lengthwise extending axis;

means for mounting said two sponge-like cleaning bodies such that the distance between said lengthwise extending axes is less than the sum of the radii of said sponge-like cleaning bodies, so that said sponge-like cleaning bodies are continuously in mutual surface contact with one another at least at portions of their circumference;

means for rotatably driving said counter-rotating sponge-like cleaning bodies at different rotational speeds, whereby said mutually contacting portions of said sponge-like cleaning bodies exert a kneading action upon one another and thus a self-cleaning acting upon one another, to thereby ensure that during cleaning of a contaminated soldering iron bit essentially only non-contaminated portions of said counter-rotating, sponge-like cleaning bodies come into contact with said contaminated soldering iron bit.
