막힘 방지 기능을 갖는 비대칭형 액상물질 주입장치{Asymmetric liquid material injection device with clogging prevention function}Asymmetric liquid material injection device with clogging prevention function

본 발명은 액상물질 주입장치에 관한 것으로, 보다 구체적으로는 디스펜서에 수용된 액상물질이 모두 배출되도록 구조를 형성하여 반복적 사용시 토출 정량을 정확하게 유지할 수 있는 막힘 방지 기능을 갖는 비대칭형 액상물질 주입장치에 관한 것이다.The present invention relates to a liquid material injection device, and more particularly, to an asymmetric liquid material injection device having a clogging prevention function capable of accurately maintaining a discharge quantity during repeated use by forming a structure so that all liquid materials contained in a dispenser are discharged will be.

일반적으로 액상물질 토출장치는 중점도 또는 고점도를 갖는 액상물질을 정량으로 토출하는데 사용되는 장치로써, 반도체, 광학제품, 가전제품 등 다양한 분야에서 몰딩, 접착, 실링 작업에 주로 이용되고 있다.In general, a liquid material discharge device is a device used to quantitatively discharge a liquid material having a medium or high viscosity, and is mainly used for molding, bonding, and sealing operations in various fields such as semiconductors, optical products, and home appliances.

이러한 액상물질 토출장치는 통상적으로 솔레노이드밸브와 액츄에이터를 이용하여 노즐을 순간적으로 개방시켜 액상물질을 토출시키는 방식과, 모터와 로터를 이용하여 액상물질이 충전된 통로에서 로터를 회전시킴으로써 액상물질을 이송시켜 이송된 액상물질을 토출시키는 방식으로 구분될 수 있다. Such a liquid material discharging device typically uses a solenoid valve and an actuator to momentarily open a nozzle to discharge a liquid material, and a motor and a rotor to rotate a rotor in a passage filled with liquid material to transfer the liquid material. It can be divided into a method of discharging the transferred liquid material.

특히 반도체, 광학제품, 가전제품 등의 정밀함을 요구하는 분야에서 다소 정밀도가 필요한 경우, 상기한 토출 방식 중에서 액상물질의 연속적인 정량 토출을 위해 모터와 로터를 이용하여 액상물질을 토출시키는 방식이 주로 이용되어 왔다.In particular, when some precision is required in fields that require precision such as semiconductors, optical products, and home appliances, the method of discharging the liquid material using a motor and a rotor for continuous quantitative discharge of the liquid material among the above discharge methods is mainly has been used

이러한 액상물질 토출장치는 일반적으로 중점도 또는 고점도 액상물질이 충전되어 사용되는 경우가 일반적이다.In general, the liquid material discharging device is filled with a medium or high viscosity liquid material.

상기한 바와 같은 중점도 또는 고점도 액상물질은 도포 작업 시 상기 액상물질을 구성하고 있는 입자들이 분해되어 상기 액상물질이 고형화되는 현상이 발생하고, 이러한 고형화된 액상물질이 노즐의 분사구를 막아 균일한 도포가 불가능하여 불량률이 증대될 뿐 아니라, 디스펜서 니들의 교체 주기가 짧아 경제적으로 큰 손실을 가져오는 문제점을 갖고 있다.The medium viscosity or high viscosity liquid material as described above causes a phenomenon in which particles constituting the liquid material are decomposed during the application operation and the liquid material is solidified, and the solidified liquid material blocks the nozzle of the nozzle for uniform application This is not possible, so the defect rate increases, and the replacement cycle of the dispenser needle is short, resulting in great economic loss.

또한, 공지의 토출장치들은 액상물질의 고형화에 따른 상기 노즐의 막힘 현상을 용이하게 감지하는 기능을 구비하고 있지 않아 노즐이 막힌 상태에서 도포 작업이 수행되어 균일하지 않은 도포에 따른 불량률이 증대되고 이에 따른 경제적인 손실이 크게 발생하기도 한다.In addition, the known discharging devices do not have a function of easily detecting the clogging of the nozzle due to the solidification of the liquid material, so that the coating operation is performed in a state where the nozzle is clogged, thereby increasing the defect rate due to non-uniform application. There may be significant economic losses as a result.

특허문헌 1은 액상 혼합 토출장치에 관한 것으로, 상기 액상 혼합 토출장치는 2 이상의 액상인 원료를 개별적인 공급로로 공급하는 원료 공급장치; 일단은 상기 원료 공급장치와 결합하는 교반기 결합부재; 입구가 상기 교반기 결합부재의 타단에 결합되는 교반기 노즐; 입구가 상기 교반기 노즐의 토출구와 결합하는 노즐간 결합부재; 및 입구가 상기 노즐간 결합부재의 토출구와 결합하며, 끝단에 토출구가 형성된 도포 노즐을 포함하는 구성으로 공정 중에 폐기되는 원료를 감소시키고, 교체되는 부속품을 최소화하여 원가를 절감하며, 토출되는 양을 정밀하게 제어하는 기술을 제안하였다.Patent Document 1 relates to a liquid mixing and discharging device, the liquid mixing and discharging device comprising: a raw material supply device for supplying two or more liquid raw materials to separate supply paths; One end is a stirrer coupling member coupled to the raw material supply device; a stirrer nozzle having an inlet coupled to the other end of the stirrer coupling member; an inter-nozzle coupling member having an inlet coupled to a discharge port of the agitator nozzle; And the inlet is coupled with the discharge port of the coupling member between the nozzles, and the composition including an application nozzle having a discharge port formed at the end reduces the raw material discarded during the process, reduces the cost by minimizing the replacement parts, and reduces the amount discharged A precise control technique was proposed.

그러나, 특허문헌 1은 내부에 충전되어 있는 충전액 즉, 액상물질의 고형화에 따라 노즐의 막힘 현상을 방지하고자 하는 별도의 구성이 기재되어 있지 않다.However, Patent Document 1 does not describe a separate configuration for preventing clogging of the nozzle according to the solidification of the filling liquid filled therein, that is, the liquid material.

따라서, 상기 액상물질의 도포작업시 노즐의 막힘을 감지할 수 있고, 노즐의 막힘 현상이 감지되면 상기 노즐의 분사구를 막고 있는 고형화된 액상물질 입자들을 용이하게 제거하여 상기 충전액의 고형화에 따른 노즐의 막힘 현상을 방지하여 도포 작업의 불량률을 저감시킬 수 있도록 하는 막힘 방지 기능을 갖는 액상물질 토출장치의 개발이 요구되고 있다.Therefore, it is possible to detect the clogging of the nozzle during the application of the liquid material, and when the clogging of the nozzle is detected, the solidified liquid material particles blocking the nozzle of the nozzle are easily removed and the nozzle according to the solidification of the filling liquid There is a demand for the development of a liquid material dispensing device having a clogging prevention function that can prevent clogging and reduce the defect rate of the coating operation.

특히, 도 1에 도시와 같이, 주입장치를 토출하기 위해서는 대상물에 대응하여 45도 각도로 경사 주입하는 것이 유용하나, 디스펜서의 내측 하부에 액상물질이 잔류하여 고형화 됨으로 노즐에 막힘 형상이 발생하는 원인이 된다.In particular, as shown in FIG. 1, in order to discharge the injection device, it is useful to inject at an angle of 45 degrees in response to the object. becomes this

본 발명의 막힘 방지 기능을 갖는 비대칭형 액상물질 주입장치(10)는 도 2 내지 도 5에 도시된 바와 같이, 디스펜서(100)와 피스톤(200)의 상호 출몰 가능한 경합으로 노즐(120)을 통해 액상물질을 유입/토출시킬 수 있도록 구성될 수 있다.As shown in FIGS. 2 to 5 , the asymmetric liquid material injection device 10 having an anti-clogging function of the present invention is through the nozzle 120 in a mutually available competition between the dispenser 100 and the piston 200 . It may be configured to introduce/discharge the liquid material.

도 2에 의하면, 상기 디스펜서(100)는 내부에 액상물질을 수용하는 내부공간(130)을 갖는다.Referring to FIG. 2 , the dispenser 100 has an internal space 130 for accommodating a liquid material therein.

이때, 디스펜서(100)의 한쪽 끝에는 수용된 액상물질을 토출할 수 있는 노즐(120)이 형성되고, 반대쪽 끝에는 피스톤(200)의 로드(230)가 출몰되는 개구부(160)가 형성되며, 상기 개구부(160)의 둘레에는 플랜지(150)를 갖는다.At this time, a nozzle 120 capable of discharging the contained liquid material is formed at one end of the dispenser 100, and an opening 160 through which the rod 230 of the piston 200 protrudes and protrudes is formed at the opposite end, and the opening ( 160 has a flange 150 around the periphery.

그리고, 상기 피스톤(200)은 디스펜서(100)의 내부공간(130)을 따라 전/후진으로 이동하여 액상물질을 밀어내는 디스크(210)와, 디스펜서(100)의 개구부(160)를 통해 출몰되는 로드(230)가 디스크(210)에 일체로 연장되어 외력에 의해 디스크(210)를 전/후진시킬 수 있다.And, the piston 200 moves forward/backward along the inner space 130 of the dispenser 100 to push the liquid material out through the disk 210 and the opening 160 of the dispenser 100. The rod 230 may extend integrally to the disk 210 to move the disk 210 forward/backward by an external force.

이때, 상기 노즐(120) 측에 대응되는 디스크(210)에는 고무재질의 가압러버(220)가 더 구비될 수 있다.At this time, the disk 210 corresponding to the nozzle 120 side may further include a rubber pressure rubber 220 .

도 4에 의하면, 상기 로드(230)의 단부에 연결되는 전동기의 왕복운동에 의해 디스크(210)를 반복적으로 전/후진시켜 수용되는 액상물질을 노즐(120)을 통해 정량 토출할 수 있다.Referring to FIG. 4 , the disk 210 is repeatedly moved forward/backward by the reciprocating motion of the electric motor connected to the end of the rod 230 to discharge the liquid material accommodated in a fixed amount through the nozzle 120 .

여기서, 상기 디스펜서(100)의 내부공간(130) 중에 노즐(120) 측에 편심으로 제1경사면(110)이 형성되고, 상기 제1경사면(110)에 대응하여 상기 피스톤(200)에 제2경사면(240)이 형성될 수 있다.Here, in the inner space 130 of the dispenser 100 , a first inclined surface 110 is formed eccentrically on the nozzle 120 side, and a second inclined surface 110 is formed on the piston 200 in correspondence to the first inclined surface 110 . An inclined surface 240 may be formed.

이때, 상기 피스톤(200)의 가압러버(220)에 제2경사면(240)이 형성되는 것이 바람직하다.At this time, it is preferable that the second inclined surface 240 is formed on the pressure rubber 220 of the piston 200 .

특히, 본 발명의 막힘 방지 기능을 갖는 비대칭형 액상물질 주입장치(10)의 디스펜서(100)와 피스톤(200)이 수평 방향으로 배치되어 사용상 디스펜서(100)의 내부공간(130)에 수용된 액상물질이 노즐(120)을 통해 모두 배출될 수 있도록 상기 디스펜서(100)의 제1경사면(110)은 노즐(120)을 기준으로 상방향으로 경사 형성되고, 상기 가압러버(220)의 제2경사면(240)은 제1경사면에 대응하여 편심으로 형성될 수 있다.In particular, the dispenser 100 and the piston 200 of the asymmetric liquid material injection device 10 having a clogging prevention function of the present invention are arranged in the horizontal direction, and the liquid material accommodated in the inner space 130 of the dispenser 100 for use.

따라서, 상기 제2경사면(240)이 제1경사면(110)에 밀착되면서 제1경사면(110)을 따라 액상물질이 자중에 노즐(120)을 통해 토출될 수 있다.Accordingly, while the second inclined surface 240 is in close contact with the first inclined surface 110 , the liquid material may be discharged through the nozzle 120 in its own weight along the first inclined surface 110 .

또한, 상기 제1경사면(110)이 만나는 디스펜서(100)의 내측 모서리에는 필렛(140)이 더 형성될 수 있다.In addition, a fillet 140 may be further formed at an inner edge of the dispenser 100 where the first inclined surface 110 meets.

즉, 상기 제1경사면(110)의 각 모서리를 필렛(140) 형성하여 모서리에 액상물질이 잔류되는 것을 미리 예방할 수 있다.That is, by forming the fillet 140 at each edge of the first inclined surface 110 , it is possible to prevent the liquid material from remaining on the edge in advance.

한편, 상기 노즐(120)은 상기 피스톤(200)의 가압에 의해 상기 디스펜서(100)의 액상물질이 토출되는 노즐팁(121)과 내측에 나사산(125)이 형성되어 다른 구조물에 체결 결합되는 결합팁(123)이 이중 구조로 이루어질 수 있다.On the other hand, the nozzle 120 is a nozzle tip 121 from which the liquid material of the dispenser 100 is discharged by the pressure of the piston 200 and a thread 125 is formed on the inside to be fastened and coupled to another structure. The tip 123 may have a double structure.

그리고, 상기 플랜지(150)에 탄성부재(300)를 구비하여 작업자가 직접 피스톤(200)을 가압 작동시키며, 탄성부재(300)의 복원력에 의해 피스톤(200)을 후진 복귀시킬 수 있다.In addition, by providing the elastic member 300 on the flange 150 , the operator directly pressurizes the piston 200 , and the piston 200 can be returned backward by the restoring force of the elastic member 300 .

도 5에 도시된 수치해석 그래프에 따르면, 노즐(120)에 인접한 디스펜서(100)의 내부 상측에는 자중에 의해 노즐로 배출되고, 하측에는 액상물질의 고임 또는 고형화 현상이 발생하지 않는다.According to the numerical analysis graph shown in FIG. 5 , the inner upper side of the dispenser 100 adjacent to the nozzle 120 is discharged to the nozzle by its own weight, and the liquid material does not collect or solidify at the lower side.

상기와 같이 구성된 본 발명을 제공함으로써, 장기간 정량으로 토출되는 토출 정량을 정확하게 유지할 수 있는 효과가 있다.By providing the present invention configured as described above, there is an effect of accurately maintaining the amount of discharge that is discharged in a fixed amount for a long period of time.
