In general, as a stylus pen, a pressure (or pressure sensitive) stylus pen which applies a constant pressure on the touch screen to be recognized and a capacitive stylus pen using static electricity are used. Such stylus pens are classified into a built-in type embedded in a portable terminal and an external type used separately from the portable terminal.

Recently, a touch screen is used as a new input method in a portable terminal such as a web pad. The touch screen input method is very convenient because a desired operation or program is executed as the user directly presses various screen icons displayed on the touch screen. In this case, since the web pad is made in a small size for easy portability, the screen is also small and it is difficult to manipulate icons with a finger.

For this reason, a touch pen is used in the touch screen input method.

On the other hand, a protective film is attached to the glass surface of the touch screen (an LCD is used as an example) so that scratches or scratches are not generated on the glass surface due to the stylus pen tip when contacted with the stylus pen. At this time, the shape of the pen tip (pen tip) of the plastic material provided at the end of the stylus pen to form a sphere to minimize the contact area with the protective film of the touch screen.

When coating the conductive silicone material used as the pen tip described above, the coating film is easily peeled off due to friction when the pen tip is repeatedly contacted with the touch screen. As a result, carbon remaining on the touch screen may be contaminated by staining with hands or clothes, thereby reducing the reliability.

In addition, current capacitive touch pens for smartphones and smart tablet PCs are mostly made of conductive rubber, which is made by adding carbon to silicon. (Shore A about 70) is high and hard. As a result, when a user possessing a smart phone touches the smart phone, the power to touch the smart phone is excessively used to reduce the recognition ability of the smart phone and shorten the life of the smart phone.

Currently, most of the rubber capacitive touch pens on the market are designed to reduce the contact load by applying a hollow inside, but this can be considered in terms of reducing material costs, but only when the production cost is excessively applied. There is a problem.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a stylus pen according to an embodiment of the present invention.

Referring to FIG. 1, the stylus pen 1000 is a pen that selects a plurality of contents pre-installed in a communication terminal and instructs to perform an operation on a selected one of the plurality of contents through a touch. 100, a pointer 200, a recess 210 coupled to the upper portion of the pointer, a pen tip 300, a protective cap 400, a lid 500, and a fixing strap 510 connected to the upper portion of the lid.

As shown in FIG. 2 (a), the pointer 200 is connected to one surface of the stick type pen body 100, and then confronted with both supporting sides of the stick type pen body 100 to be attached to the stick type pen body ( By combining with 100) serves to prevent the following pen tip 300 is deformed beyond the elastic force.

Here, the pointer 200 is processed into a selected one of copper, brass, bronze, duralumin, nichrome, stainless steel, aluminum and alloys mixed with these, it is also possible to form a conductive plastic material for fast productivity.

The groove 210 formed on the pointer 200 is formed to correspond to the opening of the pen tip 300 to prevent the pen tip 300 from being separated from the pointer 200. It is manufactured in a shape or bar shape and attached to the upper part of the pointer 200.

In other words, the recess 210 secures the connection between the pointer 200 and the pen tip 300 as the recess 210 engages with the annular locking jaw formed in the opening of the pen tip 300.

The groove 210 shown in FIG. 2 (b) is formed in a round bar shape and inserted into a predetermined space provided in the pen tip 300 such that the separation between the upper portion of the pointer 200 and the pen tip 300 does not occur. It is a combination means designed to plug in.

In addition, the groove 210 shown in FIG. 2 (c) is provided with a round bar and two protrusions at both ends, respectively, so that the separation between the upper portion of the pointer 200 and the pen tip 300 does not occur. Another type of coupling means designed to be inserted and inserted into a predetermined space provided in the).

The pen tip 300 is coupled to one surface of the pointer 200 and is fixed by both supporting sides of the stick-type pen body 100. After the RTV oil is evenly mixed with silicon, carbon nanotubes, hardener and RTV oil Drying for a reference time set to evaporate is formed to have a hardness of SHORE A 10 to 15.

That is, since the pen tip 300 continuously contacting the touch panel part is formed of a non-conductive elastomer composed of silicon, carbon nanotubes, a hardener, and an RTV oil, the pen tip 300 may be easily restored to its original shape by its elastic force. .

The protective cap 400 is covered by covering the upper convex surface of the pen tip 300 to protect the upper convex surface of the pen tip 300, PET film, CNT fiber material, UV coating material, urethane, which is classified as a conductive fiber material It is formed of one selected from the coating material and the synthetic material mixed with them.

The unit fiber 410 of the protective cap 400 is formed to a thickness of 0.02 to 0.5mm, as shown in Figure 3, if the unit fiber 410 thickness of the protective cap 400 is less than 0.02mm It becomes too thin to be inferior in manufacturability and easily breaks upon contact with the touch panel part. When the thickness of the protective cap 400 is greater than 0.5 mm, the operation of the pen tip 300 to the touch panel part is not smooth.

For example, when the unit fiber 410 of the protective cap 400 is manufactured to a thickness of 0.02 mm by the deposition plating method, as shown in Figure 3 (a), the unit fiber 410 of the protective cap 400 is 0.0178 mm Based on the conductive fiber material having a thickness, 0.0002 mm nickel, 0.0007 mm copper, and 0.0002 mm nickel are sequentially stacked on one surface of the conductive fiber material, and at the same time, 0.0002 mm nickel, 0.0007 mm copper, and 0.0002 mm nickel are formed on the other surface of the conductive fiber material. Laminated sequentially.

Here, in manufacturing the unit fiber 410 of the protective cap 400, one selected from tin, cobalt, gold, and silver as an alternative to copper is easy to use, and it is also easy to use as tin instead of nickel.

In addition, a water-soluble polyurethane of 0.002 to 0.008 mm may be formed separately on the upper layer of nickel formed on the outermost layer of the protective cap 400. The reason for forming the material is that the nickel component may cause an allergy to the human body. In order to manufacture an environmentally friendly stylus pen 1000, it will be necessary to coat both outermost layers with a water-soluble polyurethane that is a harmless material.

As another example, when the unit fiber 410 of the protective cap 400 is manufactured to a thickness of 0.18 mm by the deposition plating method, the unit fiber 410 of the protective cap 400 is made of a conductive fiber material having a thickness of 0.1602 mm As a reference, 0.0018 mm nickel, 0.0063 mm copper, and 0.0018 mm nickel are sequentially stacked on one surface of the conductive fiber material, and 00.0018 mm nickel, 0.0063 mm copper, and 0.0018 mm nickel are sequentially stacked on the other surface of the conductive fiber material.

As in the above example, when manufacturing the unit fiber 410 of the protective cap 400, one selected from tin, cobalt, gold and silver as a substitute for copper, it is easy to use, note that it is also easy to use as tin instead of nickel.

In addition, a water-soluble polyurethane of 0.002 to 0.008 mm may be formed separately on the upper layer of nickel formed on the outermost layer of the protective cap 400. The reason for forming the material is that the nickel component may cause an allergy to the human body. In order to manufacture an environmentally friendly stylus pen 1000, it will be necessary to coat both outermost layers with a water-soluble polyurethane that is a harmless material.

As another example, when the unit fiber 410 of the protective cap 400 is manufactured to a thickness of 0.5 mm by the deposition plating method, the unit fiber 410 of the protective cap 400 is a conductive fiber material having a thickness of 0.445 mm 0.005 mm nickel, 0.0175 mm copper and 0.005 mm nickel are sequentially stacked on one surface of the conductive fiber material, and at the same time, 0.005 mm nickel, 0.0175 mm copper and 0.005 mm nickel are sequentially stacked on the other surface of the conductive fiber material.

As in the above example, when manufacturing the unit fiber 410 of the protective cap 400, one selected from tin, cobalt, gold and silver as a substitute for copper, it is easy to use, note that it is also easy to use as tin instead of nickel.

In addition, a water-soluble polyurethane of 0.002 to 0.008 mm may be formed separately on the upper layer of nickel formed on the outermost layer of the protective cap 400. The reason for forming the material is that the nickel component may cause an allergy to the human body. In order to manufacture an environmentally friendly stylus pen 1000, it will be necessary to coat both outermost layers with a water-soluble polyurethane that is a harmless material.

4 is a graph showing the surface contact area change of the pen tip during vertical load between the pen tip and the touch panel unit according to the embodiment of the present invention.

That is, as can be seen in Figure 4, after the stylus pen including a pen tip made of 6 mm diameter is perpendicular to the touch panel portion of the communication terminal, objects having a weight within the range of 5g to 60g alternately As a result of measuring the case applied to the upper part of the pen, it can be seen that the surface area of the pen tip in contact with the touch panel part is changed in the range of 3.5 to 8.8 mm ² .

In other words, when an object having a weight of 5 g is applied as a vertical load on the upper part of the stylus pen which is in contact with the touch panel part, the pen tip of the present invention is almost similar to the surface resistance of the human body (1 * 10 ^-6 Ωcm). Since carbon nanotubes (CNTs) are manufactured to show surface resistance (1 * 10 ^-6 Ωcm), they have a surface contact area of 3.5 mm. It can be seen that the surface contact area of 1.9mm showing a 1.6mm difference from the pen tip containing carbon nanotubes in the present invention.

In addition, when an object having a weight of 10 g is applied as a vertical load on the upper part of the stylus pen which is in contact with the touch panel portion, the pen tip of the present invention has a surface contact area of 4.2 mm for the same reason. It can be seen that the pen tip includes a surface contact area of 2.2 mm showing a 2.0 mm difference from the pen tip including the carbon nanotubes in the present invention.

In the same way, the carbon nanotubes of the present invention are applied when the objects having the weight of 15g, 20g, 25g, 30g, 35g, 40g, 45g, 50g, 55g and 60g are applied alternately with a vertical load on the top of the stylus pen. Pen tip of the present invention, including the carbon nanotubes produced by including the carbon nanotubes, even if the included pen tip has a change in surface contact area of 2.6mm difference more than the pen tip containing the conventional carbon It can be said that it is superior in terms of surface contact area change rate than the conventional pen tip, it can be seen that the touch sensitivity is more improved than the conventional pen tip when touching the touch panel unit of the communication terminal.

Here, the conventional pen tip is produced by including carbon, but had a hardness of SHORE A 10, but the pen tip of the present invention is produced by including carbon nanotubes, it is noted that the hardness of SHORE A 10 to 15 appears do.

5 is a graph showing the yield (life) of the pen tip when the pen tip is dragged in the touch panel unit of the communication terminal with a round trip frequency of 50,000 to 160,000 round trips.

That is, as can be seen in Figure 5, after the stylus pen including the pen tip abuts perpendicularly to the touch panel portion of the communication terminal, when the stylus pen is dragged over 50,000 to 160,000 times, the touch panel portion and The wear rate of the abutted pen tip is less than 0.1% before 50,000 to 130,000 drags based on 100%, and only 0.2 to 0.4% is reached when reaching 130,000 to 160,000 times. .

More specifically, with the carbon nanotubes pen tip (300, sameum as an example that produced as a 6 ㎜ diameter) of the present invention, when a drag than make up 13 and back can see that finally the wear rate is dropped from 100% In addition, even when dragged close to 160,000 round trips, it can be seen that the wear rate dropped by only 0.4% to 99.6%.

Conventional carbon-containing pen tip drastically dropped from 100% to 98.6% when dragged more than 110,000 times, and dropped to about 5.9% by 100% when it reached 160,000 times. It can be seen that a difference of about 5.5% remains with the pen tip 300 of the present invention.

Through this, it can be seen that the pen tip 300 containing the carbon nanotube of the present invention is superior in terms of wear rate than the pen tip containing the conventional carbon, even if dragging the touch panel portion at least 120,000 times or so as it is It can be seen that it is maintained.

In addition, it can be determined that the pen tip 300 including the carbon nanotubes of the present invention has no serious problem on lifespan even if the number of touch panels is dragged at least 120,000 times.

Subsequently, the lid 500 is easily removable to protect the pen tip 300 and the protective cap 400, and is covered from the upper portion of the protective cap 400 to a partial surface of the pointer 200 to protect from an impact generated by an external force. Not only the cap 400 but also serves to protect the pen tip 300 and the pointer 200.

The lid 500 may be a stick-type pen body so as to protect the stylus pen 1000 from foreign matters or impacts such as dust that may be present in the protective cap 400 and the pen tip 300 when the stylus pen 1000 is not in use. In conjunctival with 100).

The fixing strap 510 connected to the upper portion of the lid 500 connects the lid 500 and the communication terminal to each other, thereby preventing the stylus pen 1000 from being lost from the vicinity of the communication terminal in advance.

In a comprehensive description, when the stylus pen 1000 touches a touch panel unit such as a web pad, the cap 500 is removed from the stick type pen body 100, and then the stick type pen body 100 is held. The pen tip 300 touches the corresponding icon already formed on the touch panel unit.

In this case, the stylus pen 1000 may not only reduce the frictional force of the pen tip 300 in contact with the touch panel part by the protective cap 400 of the thin film form covered by the pen tip 300, but also the pen tip 300. By reducing the wear rate to the maximum, the yield (life) and the contact with the touch panel part can be improved.

In addition, since the stylus pen 1000 is formed in a simple structure including a protective cap 400 that protects the pen tip 300 and the pen tip 300 which are main components, cost and manufacturing cost may also be reduced.

6 is a flowchart illustrating a method of manufacturing a stylus pen according to an embodiment of the present invention.

The manufacturing method of the stylus pen is a manufacturing method for selecting a plurality of contents pre-installed in the communication terminal and instructing to perform an operation on a selected one of the plurality of contents through a touch.

First, as nickel, copper, and nickel are sequentially laminated on both surfaces of the conductive fiber material by the deposition plating method, protective caps, which are conductive fiber materials, are formed (S10 and S20).

As a copper substitute in the manufacture of a protective cap, it can be substituted with one selected from tin, cobalt, gold and silver.

After the protective cap is placed on the standard pen tip mold (S30), it is molded into a mold matching the pen tip mold by applying a predetermined pressure (or external force) set at 25 to 35 kgf / cm 2 per second ( S40, S50).

After the inner surface of the protective cap is painted with a standard ratio adhesive is dried for 25 to 35 minutes (S60, S70).

Here, the adhesive is a material produced by evenly mixing 54 to 73% by weight of siloxane, 25 to 32% by weight of silicic acid, 1 to 7% by weight of propanol, and 1 to 7% by weight of benzene relative to the total 100% by weight. Be careful.

After the conductive liquid is injected into the upper surface of the protective cap is dried (S80), as a solidified for a predetermined time is formed a cylindrical pen tip adhered to the protective cap (S90, S100).

That is, the conductive tip in the liquid state and the hardened material prepared in the liquid state are mixed evenly so that the pen tip has a hardness of SHORE A 10 to 15 and solidified in the liquid state.

For example, the pen tip is manufactured by containing a hardener in the conductive liquid, wherein the conductive liquid used is 67.3 to 75.7% by weight of silicon, 1.7 to 2.4% by weight of carbon nanotubes, and 7.6 to 10.1 based on the total 100% by weight. By weight of hardener and 15 to 20.2% by weight of RTV oil are produced evenly in the order specified.

At this time, the hardening material used is 60 to 79% by weight of poly dimethylsiloxane, 10 to 15% by weight of tetrapropyl orthosilicate, 10 to 15% by weight of phenyl trimethoxysilane, 0.9 to 9% by weight based on 100% by weight of the total. Produced by mixing evenly dimethyl tin di-neodecyl isler, 0.1 to 1% by weight of methyl alcohol.

As another example, the SHORE A pen tip exhibiting a hardness of 16 to 20 hardness is 55 to 65% by weight of poly dimethylsiloxane, 34 to 40% by weight of hydroxyl-based dimethylsiloxane, 1 to 5% by weight based on 100% by weight. 56-66% by weight of tetraoxyl silicate, 17-22% by weight of dioctyl carboxyl relative to 100% by weight of the conductive liquid and alpha-hydro-omega-hydroxy-polyglycol produced in a uniform order Lyne, 17-22% by weight of di & octyltindodecate, is produced by the resulting hardened material.

As another example, even if the pen tip is unmixed with the hardener in the conductive liquid, the conductive liquid may be solidified in a solid state when the temperature of 140 to 160 degrees Celsius is heated for 18 to 22 minutes.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. It can be understood that it is possible.
