Description

  The present invention relates to a stick-type dust removing tool made of a conductive material that removes dust adhering to the surface of a polarizing plate in the assembly process of a liquid crystal panel or the like, or a narrow part or corner part of various precision instruments. It is.

In recent years, liquid crystal panels have become popular in place of CRT television monitors. Despite being working in a clean environment at the parts assembly site of each manufacturer that manufactures the LCD panel, various materials (for example, polarizing plates, light guide plates, various films, the backlight itself, etc.) A great deal of effort was spent on collecting the remaining garbage. Above all, the difficulty of removing the dust scattered in places that are difficult to reach in the product was not very common. Conventionally, as one method for removing the spot dust, a shaped object such as a pencil with an eraser is used, and the eraser side of the pencil is made of a rubber having an adhesive property. .
This is the work of attaching and removing the dust adhering to the product to the adhesive rubber, and attaching and removing the adhering dust to a transfer rubber plate having a stronger adhesive force than the separately prepared adhesive rubber. Is repeated. This adhesive rubber part is attached to a removable base, and is connected to the main body by screws, so that it can be exchanged (see FIG. 2).
In addition, an adhesive rubber is inserted into a portion corresponding to the pencil core empty portion provided in the mechanical pencil-shaped main body, and a gap portion is provided at the upper portion of the main body so as to form a gap in the upper portion of the adhesive rubber. There is a pencil-type dust remover (see, for example, Patent Document 1) in which a weight is inserted into the gap portion so as to freely move up and down.
JP 2002-177910 A (see paragraphs of claims, paragraphs {0010}, {0015} to {0020} in the column of examples, see FIGS. 1 to 3)

However, in the prior art, when used for a long period of time, the adhesive rubber portion is worn and the adhesive strength is also reduced. In addition, since the adhesive surface between the pedestal and the adhesive rubber is small, the adhesive rubber is often broken and removed from the pedestal. Then, it is necessary to unscrew the rubber base of the adhesive rubber, remove it from the main body, and replace it with new adhesive rubber. However, since they are connected by screws, there is a problem that replacement takes time and labor. In addition, since the portion of the adhesive rubber that adheres to the dust has a hemispherical shape, the contact area that contacts the dust-adhering surface when removing the dust is small, and the dust is difficult to remove. In addition, there is a problem that the work must be performed while paying attention to maintaining a contact angle at which dust easily adheres.
In addition, the pencil-type dust removing tool and the lightweight article adsorbing / transferring tool of Patent Document 1 that are the prior art are certainly problems of the above-mentioned prior art. In addition, since the adhesive surface of the pedestal and the adhesive rubber is small, the adhesive rubber often breaks and comes off from the pedestal. It is necessary to replace it with rubber. ”The point has been solved, but there is a problem that it is difficult to remove dust in flat narrow portions and corners. At the same time, there is a problem in that dust is easily reattached due to the influence of the residual charge even if the corner dust is successfully removed even when the dust is removed when the dust is removed.
Therefore, in view of such circumstances, the present invention, unlike the conventional one, winds a cotton fiber around a flat flat portion that can be elastically deformed at the tip of a stick-shaped conductive body, Since the flat part including cotton fiber is covered with conductive adhesive rubber, it is possible to prevent the reattachment of dust due to static electricity, and the amount of elastic deformation changes due to the force applied by the flat part at the tip. It is an object of the present invention to provide a stick-type dust removing tool that can increase the contact area with the dust and can remove the sticking of dust existing in a narrow gap by inserting a thin flat portion.

A first invention of the present invention for solving the above-mentioned problems is a stick type dust removing tool as described in claim 1, and is as follows.
The tip of the stick-shaped conductive swab-shaped body is flattened, cotton fibers are wound around the flat tip, and the flat portion including the cotton fibers is covered with conductive adhesive rubber. .

A second invention of the present invention for solving the above-mentioned problems is a stick-type lightweight article adsorption transfer device as described in claim 2, and is as follows.
The tip of the stick-shaped conductive swab-shaped body is flattened, cotton fibers are wound around the flat tip, and the flat portion including the cotton fibers is covered with conductive adhesive rubber. .

Since the stick-type dust removing tool and the light weight article adsorption / transfer tool according to the present invention have the configuration as described above, the following effects can be obtained.
(1) Dust adhering to the liquid crystal panel and precision equipment can be removed reliably, and the thin flat part at the tip can be inserted into a narrow gap, so that the dust present in the gap can be caught with adhesive rubber and further elastic Because it has the characteristics, it is possible to remove dust efficiently by adjusting the pressing force so that it can hold dust by increasing the contact area in the surface contact state instead of line contact with the liquid crystal panel surface. .
(2) The stick-shaped body and the adhesive rubber at the tip are made of a conductive material, which prevents static electricity from being generated on the surface of the insulator due to friction such as pressing and prevents suction of dust due to static electricity. As described above, electrostatic coupling from the outside can be removed, and reattachment of dust from the other can be prevented, so that the cleaning can be performed extremely well.

  The tip of the stick-shaped conductive body is made flat with elasticity and can be deformed, and cotton fiber is wound around this flat part to have conductivity so as to cover the flat part including the cotton fiber. A stick type dust removing tool coated with an adhesive rubber and a light weight article adsorption transfer tool.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
First, the structure of the stick-type dust removing tool 1 will be described.
Conductivity is imparted to the main body 2 which is a shaft rod employed in the present invention, a flat flat portion 4 is formed at the tip of the main body 2, and cotton fibers are wound around the flat portion 4 so as to include the cotton fibers. The flat rubber portion 4 is covered with the adhesive rubber 3 by dipping or the like.
As the conductive main body 2, a conductive metal such as stainless steel, aluminum, or brass, or a plastic such as conductive polystyrene, ABS (acrylonitrile butadiene styrene), or polypropylene can be used. Further, as the adhesive rubber 3 having conductivity, polyurethane rubber, butyl rubber, silicon rubber or the like having conductivity can be adopted.

  In addition, what is described as the above-mentioned cotton fiber is not limited to cotton like a commercially available cotton swab, but may be any cotton-like one having a water-capturing ability instead of cotton, for example, chemicals such as polyester and nylon. It goes without saying that fibers are also targeted.

  In the above description, the adhesive rubber 3 having conductivity covered with the flat portion 4 wound with the cotton fiber at one end of the conductive main body 2 has been described. However, the adhesive rubber 3 having various shapes at both ends is described. By coating, it is easy to use and the usable time can be extended by a factor of two.

  The conductive adhesive rubber 3 has an adhesive force for adhering and holding fine dust and the like, and with the strength of the adhesive force, there is an influence of the transfer of rubber quality from the adhesive rubber itself to the object to be cleaned. It is covered only with pure rubber that does not affect the surface.

However, since the conductive adhesive rubber 3 is coated on the flat portion 4 including the cotton fibers of the conductive main body 2, it is disposable if the adhesive force deteriorates while the dust is removed. . In addition, the shape of the front end portion of the conductive main body 2 is slightly inferior even if it is not flat, but the cross-sectional shape is a columnar shape, a triangular prism shape, a quadrangular prism shape, etc. The same effect is produced.
Note that, as a precaution, when the flat portion 4 provided at the tip of the conductive main body 2 is formed of a non-conductive material, the whole is covered with the conductive adhesive rubber 3. Needless to say, it is better to completely cover the flat portion having no conductivity.

Next, the conductive adhesive rubber 3 will be described more specifically.
Most of the conductive adhesive rubber 3 is mainly composed of urethane rubber, silicon rubber, or butyl rubber, and its adhesive strength has an inversely proportional relationship with the finished hardness.
That is, as the degree of polymerization increases, the hardness increases and at the same time the adhesive strength decreases. In other words, dust adheres to the medium (for example, a tape, a sheet, a polarizing plate, and a glass plate) to which the dust adheres, and the adhesive prevents the rubber component from transferring to the medium. The adjustment of the force is a point for maintaining the function of the conductive adhesive rubber 3.

  In addition, most of the commercially available adhesive rubbers are those that have been added with a pigment so as to exhibit light blue, light green, light gray, etc. so that the adhesion of dust can be easily confirmed. However, on the other hand, the presence of the pigment is not preferable, and there is a view that an additive-free transparent one is better.

  Moreover, it can utilize also for transferring a lightweight article from A point to B point by the adsorption | suction effect | action of the adhesive rubber 3 which has electroconductivity.

  It can be used not only for removing dust adhering to liquid crystal panels and precision equipment, but also for cleaning electrical equipment at home.

It is a perspective view which shows the stick type | mold dust removal tool and adsorption | suction transfer tool of a lightweight article of this invention. It is a perspective view which shows the conventional dust removal tool.
