Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and the same reference numerals in each drawing refer to the same components.

2 is a perspective view showing a basic embodiment of the external structure of the horn to which the tip of the present invention is coupled.

As can be seen from Figure 2, the horn 10 of the present invention is based on the body 100 and the tip 200 is combined.

The main body 100 may be a known horn 10 that transmits the ultrasonic vibration energy generated by the vibrator to the object, and the known horn 10 is a bar horn, a block horn, and a step It can be made in various shapes such as a stepped horn.

Among them, a bar horn is a shape that can effectively transmit ultrasonic vibration energy to a cleaning solution, and can be used generally compared to a conical step horn and a simple block horn having insufficient transmission power. As illustrated, the main body 100 is made of a bar horn.

In addition, as can be seen from FIG. 2, the main body 100 in the shape of a bar horn has a surface providing an area to which the tip 200 to be described later can be coupled, that is, the upper surface 110 of the main body (in FIG. The main body 100 and the tip 200 are in contact with each other).

At this time, the upper surface 110 of the main body may be formed in various shapes such as a rectangle, an ellipse, and a square, but in FIG. 2, the upper surface 110 of the main body is known in the shape of the upper surface 110 of the main body of a bar horn. It is illustrated that it is made of a rectangular flat surface extending in the longitudinal direction (the width direction of the main body 100 when looking at FIG. 2).

The main body 100 may be made of a material that is easy to transmit ultrasonic vibration energy, and such a material is generally a metal material such as aluminum, titanium, and steel. In the present invention, the metal material forming the main body 100 is' It is called'first metal material'.

This body 100 can be coupled to the booster through a face facing down when looking at FIG. 2, that is, a coupling face. The body 100 and the booster can be coupled through fasteners or screws, but are provided integrally with ultrasonic waves. It is also possible to minimize the loss of vibration energy.

The tip 200 is coupled to the upper surface 110 of the main body, and the tip 200 and the main body 100 may be combined in various ways such as insertion bonding, use of a metal adhesive, and brazing.

The tip 200 has a width corresponding to the width of the top surface 110 of the body and has a constant thickness (height), and the thickness of the tip 200 is through the tip 200. It can be made in various thicknesses that do not impede the transmission of ultrasonic vibration energy.

That is, the tip 200 may have a plate-like shape as shown in FIG. 2 depending on the thickness, as well as a bar shape such as a rectangular parallelepiped.

In addition, the fact that the width of the tip 200 corresponds to the width of the upper surface 110 of the main body is that when there is a difference in the width of the tip 200 and the upper surface 110 of the main body, the tip 200 protrudes or This is because when a part of the upper surface 110 is exposed, ultrasonic vibration energy may be lost through the protruding or exposed surface.

The material of the tip 200 may be a metal material such as iron, titanium, carbide, etc. having a bulk modulus higher than that of the first metal material, and the metal material forming the tip 200 is used in the present invention. It is called'metal material'.

At this time, the cannibalization of the propagation speed of the wave through the medium

를 보아 알 수 있듯이 파동의 전파 속도는 체적탄성계수의 제곱근에 비례하고 매질 밀도의 제곱근에 반비례하는데, 다시 말해 체적탄성계수가 큰 제 2 금속재는 제 1 금속재에 비하여 초음파 진동에너지를 잘 전달하여 본 발명의 혼(10)의 출력을 높일 수 있고, 초음파 진동에너지가 팁(200) 방향으로 발산되도록 유도할 수도 있다.

As can be seen, the propagation speed of a wave is proportional to the square root of the volumetric modulus and inversely proportional to the square root of the medium density.In other words, the second metal material with a larger volumetric modulus transmits ultrasonic vibration energy better than the first metal material. The output of the horn 10 of the invention may be increased, and ultrasonic vibration energy may be induced to be radiated toward the tip 200.

In addition, in the case of ultrasonic vibration energy transmission through the tip 200, the above-described equation of the propagation speed is dominantly corrected in the volume modulus rather than the density of the second metal material by reflecting the thinner characteristics of the tip 200 compared to the main body 100. It could be.

In summary, the horn 10 of the present invention increases the output of ultrasonic vibration energy by combining a tip 200 made of a second metal material having a high volume modulus to the body 100, and the ultrasonic vibration energy is applied to the object (washing or processing, etc.). It provides a characteristic that can be induced to diverge toward the upper surface 110 of the main body installed toward the target).

Further, the first metal material described above may be made of aluminum, and the second metal material may be made of iron.

As described above, the first metal material may be aluminum, lithium sulfate, molybdenum, and the like. Of these, lithium sulfate is known as a material that can transmit ultrasonic vibration energy very effectively, but it is decomposed in water, so there are restrictions on use, and molybdenum is It is a material with a calendar and excellent durability, but it is difficult to process and has a high cost due to its strong mechanical strength.

Therefore, it is preferable that the first metal material is made of aluminum, and aluminum has a low density and light so that it can transmit ultrasonic vibration energy well, and, as is well known, it is a metal that has the largest amount in the soil and has a low cost burden. It is a metal that has the advantage of being easy to process. In addition, the volume modulus of aluminum is 7.46*10 ² kgf/cm ² .

As described above, the second metal material may be iron, cobalt, nickel, etc., of which cobalt is classified as a material with a volume modulus of 1.87*10 ³ kgf/cm ² higher than aluminum or rare earths, and its production area is limited, making it difficult to supply in large quantities. , Nickel is a material having a volume modulus of 1.89*10 ³ kgf/cm ² , but its density is high, so the propagation speed is lowered and the weight of the tip 200 may be excessively heavy.

Therefore, it is preferable that the second metal material is made of iron, and iron has a volume modulus of 1.83*10 ³ kgf/cm ² , which is higher than that of aluminum, so that ultrasonic vibration energy can be effectively transmitted, and a processing method is also widely known.

In other words, since the first metal material is made of aluminum and the second metal material is made of iron, the horn 10 of the present invention can implement a function of amplifying the ultrasonic vibration energy and inducing it to be radiated toward the upper surface 110 of the main body. Of course, iron having a mechanical strength higher than that of aluminum is made of a second metal material to provide a characteristic of protecting the upper surface 110 of the body which is easily worn by ultrasonic vibration.

In addition, since aluminum, which is the first metal material, has high thermal conductivity, it can easily dissipate heat generated during the ultrasonic operation to prevent the frequency of the ultrasonic wave from changing when the heat of the medium increases. Through this, the target of the horn 10 of the present invention It is also possible to improve the quality of the horn and extend the life of the horn (10).

3 is an exploded perspective view showing a modified embodiment of the external structure of the horn to which the tip of the present invention is coupled.

As can be seen from FIG. 3, a tip hole 120 may be recessed in the upper surface 110 of the main body.

The tip hole 120 is recessed along the length direction of the upper surface 110 of the body (the width direction of the upper surface 110 in FIG. 3), and may be recessed in various shapes such as a circle, a square, and a rectangle along the length direction. have. Here, the depth at which the tip hole 120 is inserted may be an appropriate depth at which the coupling block 220, which will be described later, can be inserted.

In addition, the tip hole 120 may be formed as if extending along the length direction. Referring to FIG. 3, for example, the tip hole 120 extends in a rectangular shape and is recessed, so that the inside of the tip hole 120 has a rectangular parallelepiped shape. Space can be formed.

At this time, since the tip holes 120 may be formed in plural, the plurality of tip holes 120 may be formed in two along the length direction as shown in FIG. 3, but a larger number or matrix structure may be formed. It is possible. In addition, the plurality of tip holes 120 formed in this way may be formed at regular intervals.

Correspondingly, the coupling block 220 may be formed on the bottom surface 210 of the tip, that is, the surface where the upper surface 110 and the tip 200 of the main body contact each other.

The coupling block 220 is formed protruding from the bottom surface 210 of the tip, and is protruded in a size and shape corresponding to the size and shape of the tip hole 120 so that the coupling block 220 is inserted and coupled to the tip hole 120 Can be.

That is, since the coupling block 220 may be formed to protrude in the same number as the plurality of tip holes 120, a specific method of inserting and coupling the coupling block 220 into the tip hole 120 will be described later.

In summary, the main body 100 and the tip 200 of the present invention include the tip hole 120 and the coupling block 220 to provide a characteristic that can be inserted and coupled to be stronger than that of a flat surface.

Figure 4 is a flow chart showing a method of manufacturing the horn of the present invention.

The manufacturing method of the horn 10 of the present invention is to ensure a solid uneven coupling between the upper surface 110 of the body having the above-described tip hole 120 and the bottom surface 210 of the tip having the coupling block 220 As a basis, it is specifically composed of three steps.

In other words, as can be seen from FIG. 4, the horn 10 of the present invention may be manufactured through a first step (S100), a second step (S110), and a third step (S120).

The first step (S100) is a step of expanding the tip hole 120 by heating the main body 100 at 150 to 450° C. for 1 to 2 hours. At this time, the melting point of aluminum, which is the first metal material, is known to have a melting point of 660°C. During the first step (S100), a phase change does not occur with a solution, and the coefficient of thermal expansion is 23.8*10 ^-6 mm/°C. It is included in the tip hole 120 through the first step (S100) is expanded, the coupling block 220 can be easily seated.

The second step S110 is a step of seating the tip 200 on the upper surface 110 of the main body so that the coupling block 220 of the tip 200 is inserted into the tip hole 120. Here, it may be seated as if the coupling block 220 is inserted into the expanded tip hole 120 through the first step (S100).

The third step (S120) is a step of cooling the main body 100 to which the tip 200 is coupled, and the tip hole 120 expanded by heating is re-contracted so that the tip hole 120 and the coupling block 220 are Can be firmly inserted and coupled. In addition, the third step (S120) may be quickly cooled at a low temperature, but gradually cooling at room temperature for 1 to 2 hours is preferable because cracking of the main body 100 can be prevented.

In other words, through the first, second, and third steps described above, the main body 100 and the tip 200 form a solid uneven coupling, so that they may not be easily separated by ultrasonic vibration energy.

Furthermore, the above-described first step S100 may include a first heating step and a second heating step. That is, it is preferable that the first step S100 is performed in a furnace or a heating chamber in which a heating segment can be set.

The first heating step is a step of raising the temperature of the main body 100 from 150 to 200° C. at a rate of 3 to 5° C. per minute for 30 to 60 minutes. In this case, by gradually increasing the heating temperature, it is possible to prevent the occurrence of microcracks due to rapid heating of aluminum having a large coefficient of thermal expansion.

The second heating step is a step of raising the body 100 to 150 to 200°C at a heating rate of 2 to 4°C per minute for 30 to 60 minutes, and having a lower heating rate than the first heating step is heated to a certain temperature level. This is to adjust the shape of the body 100 to reach the melting point so that it does not collapse.

In summary, by separating the first step (S100) into the first and second heating steps, it is possible to prevent the body 100 of the present invention from being destroyed or deformed by heat.

Furthermore, between the first and second heating steps, a step of applying 1 to 5% by volume of ETFE (Ethylene Tetra fluoro Ethylene) powder to the tip hole 120 relative to the inner volume of the tip hole 120 may be added. I can.

At this time, ETFE is a material that serves to prevent aluminum, which is the first metal material, from being oxidized, and is gradually removed at a temperature of 300°C or higher, so that the entire amount can be removed when the second heating step is finished.

In addition, aluminum is easily thermally oxidized at high temperatures to form alumina (Al ₂ O ₃ ). Alumina is a material that exhibits ceramic properties, not metallic properties, and can be ruptured by ultrasonic vibration energy, as well as first metal materials and materials. 2 Diffraction may occur when ultrasonic vibration energy passes through the interface by forming a new interface between metal materials.

Therefore, by applying ETFE to prevent oxidation in the tip hole 120 into which the coupling block 220 is inserted, the formation of a ceramic-metal interface by alumina is prevented, and ultrasonic vibration energy is easily transmitted through the tip 200. Can be lost.

As another embodiment, the above-described second step (S110) may include an adhesive film including propylene oxide and butanon oxime.

Specifically, the adhesive film may be applied to any one or more of the standing walls of the tip hole 120 before being seated as if the coupling block 220 is inserted into the tip hole 120, during the first step (S100) After being dissolved by the heat of the heated body 100, the tip hole 120 and the coupling block 220 may be attached by being solidified again through the third step S120, which is a cooling step.

A specific method of manufacturing such an adhesive film is as follows.

Figure 5 is a flow chart showing a method of manufacturing the adhesive film of the present invention.

The adhesive film may be manufactured through a first material manufacturing step (S200), a second material manufacturing step (S210), a third material manufacturing step (S220), and an injection step (S230).

First, the first material manufacturing step (S200) is a mixture of 50 to 60 parts by weight of propylene oxide, 30 to 40 parts by weight of sorbitol, and 5 to 10 parts by weight of potassium hydroxide at 150 to 180°C for 5 to 7 hours. It is the process of manufacturing a substance.

Here, propylene oxide is a material capable of producing a polyether-based polyol through ring-opening polymerization in which a ring contained in a molecule is opened, and sorbitol is a polyvalent polyol including six hydroxyl groups (-OH) including active hydrogen. Since a polyol can be prepared, an adhesive film prepared including a polyhydric polyol can have reinforced adhesion. In addition, potassium hydroxide serves as a basic ion catalyst.

Next, the secondary material manufacturing step (S210) is to prepare a secondary material by mixing 60 to 70 parts by weight of Toluene diisocyanate (TDI) and 25 to 35 parts by weight of cyclohexanone at 60 to 80°C for 1 to 3 hours. It is a process.

At this time, TDI is one of the isocyanates and can be polymerized with a primary material, which is a polyol, in a tertiary material manufacturing step (S220) to be described later, to produce a polyurethane-based polymer, and cyclohexanone is a secondary material. It is a solvent to dissolve and disperse.

Subsequently, the third material manufacturing step (S220) includes 35 to 45 parts by weight of the primary material, 35 to 45 parts by weight of the secondary material, 15 to 25 parts by weight of glycerin, and 1 to 5 parts by weight of DBTL (Dibutyltin dilaurate) at 60 to 80°C. It is a process of preparing a tertiary material by mixing for 1 to 3 hours.

Here, the tertiary material is a polyurethane-based material in which a primary material and a secondary material are polymerized as described above, and glycerin is a material having three hydroxyl groups, forming a long chain of the tertiary material and reinforcing adhesion by replenishing hydroxyl groups. Play a role. In addition, DBTL acts as a catalyst to reduce the polymerization temperature and time.

Finally, the injection step (S230) is a process of mixing 60 to 80 parts by weight of a tertiary substance and 20 to 40 parts by weight of butanone oxime at 150 to 180°C for 1 to 3 hours, and then injecting to a thickness of 0.05 to 1 mm.

Here, butanone oxime is a material that plays a role of stopping polymerization by substituting an isocyanate group (-NCO) of the tertiary material terminal, and can form an adhesive film that is not a completely solid state and inject it to a predetermined thickness. At this time, injection can be performed in various ways such as a roller capable of injecting a film shape, uniaxial pressurization, and biaxial pressurization.

In summary, the adhesive film of the present invention is a material showing adhesiveness and thermoplasticity, which is included in the second step (S110), melted by heat, and then returns to a solid state during cooling of the third step (S120), and the tip hole ( 120) and the coupling block 220 serves to securely insert coupling.

Further, the above-described injection step (S230) may include an adhesion promoter including aminopropyltriethoxysilane (APS) and ortho-hydroxybenzylamine (OHBA).

Specifically, the injection step (S230) is a tertiary material 60 to 70 parts by weight, butanone oxime 20 to 30 parts by weight, APS (Aminopropyltriethoxysilane) and OHBA (ortho-hydroxybenzylamine) 10 to 15 parts by weight of an adhesion promoter containing 150 to 150 to It may be a process of mixing at 180° C. for 1 to 3 hours and then injecting to a thickness of 0.05 to 1 mm.

Here, APS is a silane-based chelating agent and can reinforce the adhesion of the adhesive film by forming a metal-oxygen-silicon bond, and OHBA is a polymer-based chelating agent, forming metal and insoluble salts to reinforce the adhesion of the adhesive film. It is a substance that can do.

The adhesion promoter including APS and OHBA may be prepared through a first solution preparation step, a second solution preparation step, and a mixing step.

First, in the first solution preparation step, 50 to 60 parts by weight of APS, 20 to 30 parts by weight of water, and 20 to 30 parts by weight of phosphoric acid (H ₃ PO ₄ ) are mixed at 50 to 70° C. for 1 to 3 hours to prepare the first solution. It is a manufacturing process.

Here, APS is a silane-based chelating agent as described above, and water is a solvent for dissolving and dispersing APS. In addition, since phosphoric acid serves to adjust the pH of the first solution to an acidic atmosphere, the pH of the first solution is preferably adjusted to 3 to 4.

Subsequently, the second solution preparation step is to prepare a second solution by mixing 50 to 60 parts by weight of OHBA, 30 to 40 parts by weight of ethanol, and 5 to 15 parts by weight of dimethyl sulfoxide (DMSO) at 50 to 70° C. for 1 to 3 hours. It's a process.

At this time, OHBA is a polymer-based chelating agent as described above, and ethanol is a solvent that dissolves and disperses OHBA, and OHBA is not easily soluble in the solvent, so the polarity of the solvent further includes DMSO, an aprotic polar solvent. Can strengthen.

Finally, the mixing step is a process of mixing 50 to 60 parts by weight of the first solution and 40 to 50 parts by weight of the second solution at 120 to 150°C for 2 to 4 hours, and the adhesion promoter may be completed through the mixing step.

The adhesion promoter prepared through this process includes silane-based and polymer-based chelating agents to reinforce the adhesion of the adhesive film so that the insertion and bonding of the tip hole 120 and the bonding block 220 are not easily released by ultrasonic vibration energy. It provides the function to do.
