Description

보텍스 코팅건Vortex Coating Gun
본 발명은 기판 등에 컨포멀 코팅을 하기 위한 보텍스 코팅건에 관한 것이다. 여기서, 보텍스 코팅건은 니들 코팅건과 멤브레인 코팅건의 기능을 선택적으로 사용할 수 있는 코팅건을 의미한다.The present invention relates to a vortex coating gun for conformal coating on a substrate or the like. Here, the vortex coating gun means a coating gun that can selectively use the functions of the needle coating gun and the membrane coating gun.
코팅건은 기판 등에 컨포멀 코팅을 하기 위해 사용된다. 여기서, 컨포멀 코팅이란 기판 상으로 유전체 물질을 도포하는 공정을 의미한다. Coating guns are used to conformally coat substrates and the like. Here, conformal coating means a process of applying a dielectric material onto a substrate.
일반적으로, 컨포멀 코팅에 사용되는 코팅액은 실리콘, 아크릴, 폴리우레탄, 에폭시, 합성 수지 및 다양한 포리머들을 포함한다. 상기한 코팅액이 코팅건에 의해 분사되어 기판 상에 도포되어 막을 형성한다. 이렇게 도포되어 막을 형성한 코팅액은, 습기, 곰팡이, 먼지, 부식, 마모 및 다른 이물질 등으로부터 기판을 보호하는 역할을 한다. Generally, coating liquids used in conformal coatings include silicones, acrylics, polyurethanes, epoxies, synthetic resins and various polymers. The coating solution is sprayed by a coating gun and applied onto a substrate to form a film. The coating liquid thus applied to form a film serves to protect the substrate from moisture, mold, dust, corrosion, abrasion, and other foreign matter.
코팅건은 분사 방식에 따라 크게 니들 코팅건(Needle Coating Gun)과 멤브레인 코팅건(Membrane Coating Gun)으로 구분된다. 니들 코팅건에 의해 분사되는 코팅액은 일직선으로 분사되며, 멤브레인 코팅건에 의해 분사되는 코팅액은 분사노즐로부터 멀어질수록 도포폭이 커지도록 퍼지며 분사된다.Coating guns are divided into needle coating gun and membrane coating gun according to the spraying method. The coating liquid sprayed by the needle coating gun is sprayed in a straight line, and the coating liquid sprayed by the membrane coating gun is spread and spread so that the coating width increases as it is far from the spray nozzle.
종래의 니들 코팅건은 일직선으로만 분사되므로 기판 상의 좁은 공간을 코팅하기 위해서는 유리하지만 넓은 면적을 코팅하기 위해서는 지나치게 많은 시간과 인력이 낭비되는 문제가 있다.Conventional needle coating gun is sprayed only in a straight line is advantageous for coating a narrow space on the substrate, but there is a problem that too much time and manpower is wasted to coat a large area.
또한, 종래의 멤브레인 코팅건은 퍼지는 형태로만 분사되므로 기판 상의 좁은 공간을 코팅하기 위해서는 사용할 수 없다. 특히, 종래의 멤브레인 코팅건은 분사되는 코팅액을 퍼뜨리기 위해 고압의 공기를 주입하는데, 이 경우 고압의 공기와 만나 비산하는 코팅액의 양이 많아 멤브레인 코팅건을 사용하는 주변이 뿌옇게 보일 정도이며, 기판에 닿는 코팅액의 속도도 빨라 기판에 닿는 코팅액 중에서도 약 30% 정도만이 기판에 도포되고 나머지는 튕겨져 나가 비산하는 문제점이 있다.In addition, the conventional membrane coating gun is sprayed only in the form of spreading, so it cannot be used to coat a narrow space on the substrate. In particular, the conventional membrane coating gun injects high-pressure air to spread the sprayed coating liquid, in which case the amount of coating liquid that meets and scatters with the high-pressure air is so high that the surroundings of the membrane coating gun appear cloudy. The speed of the coating liquid to reach the speed is also fast, only about 30% of the coating liquid in contact with the substrate is applied to the substrate and the rest is bounced off there is a problem.

도 1을 참조하면, 본 발명의 일례에 따른 보텍스 코팅건은 분사부(100), 개폐부(200), 및 개폐량 조절부(300)를 포함할 수 있다.Referring to FIG. 1, the vortex coating gun according to the exemplary embodiment of the present invention may include an injection part 100, an opening and closing part 200, and an opening and closing amount adjusting part 300.
분사부(100)는, 개폐부(200)와 연결되어 개폐부(200)가 코팅액(40)의 유동을 개방하는 경우 코팅액(40)을 분사하는 역할을 한다.The injection part 100 is connected to the opening and closing part 200 and serves to inject the coating liquid 40 when the opening and closing part 200 opens the flow of the coating liquid 40.
분사부(100)는, 일례로서 도 2에 도시된 바와 같이 노즐캡(110), 보텍스 에어 노즐(120), 연결 바디(130), 주사기(140), 주사기 조립 너트(150), 주사기 실링 캡(160), 및 분리 바디(170)를 포함할 수 있다.As shown in FIG. 2, the injection unit 100 includes, for example, a nozzle cap 110, a vortex air nozzle 120, a connection body 130, a syringe 140, a syringe assembly nut 150, and a syringe sealing cap. 160, and separation body 170.

When the length of the vortex air nozzle 120 is secured for a predetermined length or more, the spray radius of the coating liquid may be sufficiently widened by simply introducing low pressure air through the injection air inlet 20.

The air flowing through the space between the connecting body 130 and the injector 140 passes through the plurality of recesses 122 of the vortex air nozzle 120 supported and fixed in front of the connecting body 130. The flow of air will be described later in detail.

The syringe 140 is screwed to the syringe assembly nut 150 as shown in FIG. 2 as an example. In this case, when the coating solution 40 is hardened and clogged inside the syringe 140, there is an advantage that only the syringe 140 can be easily replaced.
주사기 조립 너트(150)는, 주사기(140) 및 분리 바디(170)를 연결한다. 살핀 바와 같이, 주사기 조립 너트(150)의 전방에는 주사기(140)가 나사 결합되며 주사기 조립 너트(150)의 후방에는 분리 바디(170)가 나사 결합된다. 주사기 조립 너트(150) 내부에는 주사기 실링 캡(160)이 구비된다.The syringe assembly nut 150 connects the syringe 140 and the separating body 170.

개폐부(200)는, 코팅액(40)이 유입되는 코팅액 유입구(10)를 포함하며 상기 코팅액 유입구(10)를 통해 유입된 코팅액(40)의 유동을 선택적으로 개폐하는 역할을 한다.The opening and closing part 200 includes a coating liquid inlet 10 through which the coating liquid 40 flows, and selectively opens and closes the flow of the coating liquid 40 introduced through the coating liquid inlet 10.
개폐부(200)는, 일례로서 도 2에 도시된 바와 같이 개폐 공이(210), 공이 연결부(220), 탄성부재 가이드(230), 탄성부재(240), 메인바디(250), 에어 실린더 샤프트(260), 에어 실린더 샤프트 고정 너트(270), 스냅링(280), 접시 스프링 고정부(291), 접시 스프링(290), 및 접시 스프링 수용부(292)를 포함할 수 있다.Opening and closing portion 200, for example, as shown in Figure 2 opening and closing ball 210, the ball connecting portion 220, elastic member guide 230, elastic member 240, main body 250, air cylinder shaft ( 260, an air cylinder shaft retaining nut 270, a snap ring 280, a dish spring fixture 291, a dish spring 290, and a dish spring receiving portion 292.
개폐 공이(210)는, 후술할 공이 연결부(220)와 연결되며 분리 바디(170)의 개폐공(175)을 선택적으로 개폐하는 역할을 한다. 즉, 개폐 공이(210)가 개폐공(175)에 삽입되면 코팅액(40)이 개폐공(175)을 통과할 수 없는 상태가 되고, 개폐 공이(210)가 개폐공(175)으로부터 이격되면 코팅액(40)이 개폐공(175)을 통과할 수 있는 상태가 된다.Opening and closing ball 210, the ball to be described later is connected to the connecting portion 220 serves to selectively open and close the opening and closing hole 175 of the separating body 170. That is, when the opening and closing ball 210 is inserted into the opening and closing hole 175, the coating liquid 40 cannot pass through the opening and closing hole 175, and when the opening and closing ball 210 is spaced apart from the opening and closing hole 175, the coating liquid. 40 is in a state capable of passing through the opening and closing hole (175).
개폐 공이(210)는, 전방으로 갈수록 지름이 좁아지는 경사면(211)을 포함할 수 있다.The opening and closing ball 210 may include an inclined surface 211, the diameter of which is narrowed toward the front.
경사면(211)의 전방에 코팅액(40)이 유입되면 경사면(211)을 후방으로 밀게되고 이 힘에 의해 개폐 공이(210)는 후방으로 밀릴 수 있다. 그러나, 개폐 공이(210)는 후방에 공이 연결부(220)와 연결되어 있어 공이 연결부(220)가 후방으로의 이동이 제한된 상황이라면 개폐 공이(210) 역시 후방으로 이동될 수 없다.When the coating liquid 40 flows in front of the inclined surface 211, the inclined surface 211 is pushed backward, and the opening and closing ball 210 may be pushed backward by this force. However, the opening and closing ball 210 is the ball is connected to the connecting portion 220 at the rear, so that the opening and closing ball 210 can also be moved to the rear if the ball connection portion 220 is limited to the rear movement.
공이 연결부(220)는, 개폐 공이(210) 및 후술할 에어 실린더 샤프트(260)를 연결하는 역할을 한다. 즉, 개폐 공이(210)의 이동력을 에어 실린더 샤프트(260)에 제공하거나 에어 실린더 샤프트(260)의 이동력을 개폐 공이(210)에 제공한다.The ball connection part 220 serves to connect the opening and closing ball 210 and the air cylinder shaft 260 to be described later. That is, the moving force of the opening and closing ball 210 is provided to the air cylinder shaft 260 or the moving force of the air cylinder shaft 260 is provided to the opening and closing ball 210.
다만, 공이 연결부(220)는, 개폐 공이(210) 및 에어 실린더 샤프트(260)와 분리된 부재이므로 개폐 공이(210) 또는 에어 실린더 샤프트(260) 중 어느 한 부재와는 이격되어 이동될 수 있다.However, since the ball connection part 220 is a member separated from the opening / closing ball 210 and the air cylinder shaft 260, the ball opening part 220 may be moved away from any one of the opening / closing ball 210 or the air cylinder shaft 260. .
공이 연결부(220)는, 일례로서 도 2에 도시된 바와 같이 돌출부(221)를 포함할 수 있다.The ball connecting portion 220 may include a protrusion 221 as shown in FIG. 2 as an example.
돌출부(221)는, 공이 연결부(220)의 외주면으로부터 외측으로 돌출되어 구비된다. 돌출부(221)는 후술할 탄성부재 가이드(230)의 전단이 접하게 되며 탄성부재(240)의 탄성력이 전달되는 부분이 된다.The protruding portion 221 is provided with a ball protruding outward from the outer circumferential surface of the connecting portion 220. The protruding portion 221 is in contact with the front end of the elastic member guide 230 to be described later and becomes a portion to which the elastic force of the elastic member 240 is transmitted.
즉, 메인바디(250)의 내측에 구비되는 탄성부재 지지부(251)에 일단이 지지되는 탄성부재(240)는, 타단에 지지되는 돌출부(221)를 밀어내는 방향으로 탄성력을 제공한다. 이에 따라, 공이 연결부(220) 전체가 전진하려는 힘을 받게 된다. 이와 같은 공이 연결부(220)의 움직임은 에어 실린더 샤프트(260)와는 별개의 움직임을 유의해야 한다.That is, the elastic member 240 having one end supported by the elastic member support part 251 provided inside the main body 250 provides an elastic force in the direction of pushing the protrusion 221 supported at the other end. Accordingly, the ball is subjected to the force to move the entire connecting portion 220. The movement of the ball connecting portion 220 should be noted that the movement separate from the air cylinder shaft 260.
따라서, 이 경우 에어 실린더 샤프트(260)가 후방으로 밀려난 상황일지라도 코팅액(40)이 충분히 공급되지 않으면 공이 연결부(220) 및 개폐 공이(210)는 개폐공(175)을 닫게 된다. 이를 통해, 공급액(40)의 공급이 원활하지 않은 경우에는 일정량 이상의 공급액(40)이 개폐 공이(210)의 경사면(211) 전방에 모여 경사면(211)을 충분한 힘으로 밀어내는 경우에만 개폐공(175)이 열리게 된다. 즉, 코팅액(40)이 부족하게 분사되는 현상이 최소화되는 것이다. 이를 통해, 사용자는 일정한 폭의 컨포멀 코팅을 수행할 수 있는 장점이 있다.Therefore, in this case, even when the air cylinder shaft 260 is pushed backward, if the coating liquid 40 is not sufficiently supplied, the ball connecting portion 220 and the opening and closing ball 210 will close the opening and closing hole 175. Through this, when the supply of the supply liquid 40 is not smooth, the opening and closing hole only when a predetermined amount or more of the supply liquid 40 gathers in front of the inclined surface 211 of the opening and closing ball 210 and pushes the inclined surface 211 with sufficient force. 175) is opened. That is, the phenomenon that the coating liquid 40 is insufficiently sprayed is minimized. Through this, the user has the advantage of performing a conformal coating of a constant width.
앞서, 개폐 공이(210) 및 공이 연결부(220)를 별도의 부재로 설명하였으나, 개폐 공이(210) 및 공이 연결부(220)는 일체의 부재로 형성될 수 있다. 다만, 양자가 별도의 부재로 구비되는 경우, 다양한 사이즈의 보텍스 코팅건에 개폐 공이(210) 및 공이 연결부(220)가 사용될 수 있는 장점이 있다.Although the opening and closing ball 210 and the ball connecting portion 220 has been described as a separate member, the opening and closing ball 210 and the ball connecting portion 220 may be formed as an integral member. However, when both are provided as a separate member, there is an advantage that the opening and closing ball 210 and the ball connecting portion 220 can be used in the vortex coating gun of various sizes.
탄성부재 가이드(230)는, 공이 연결부(220)의 적어도 일부를 수용하며 공이 연결부(220)의 돌출부(221)와 접하고 후술할 탄성부재(240)를 가이드 하는 역할을 한다.The elastic member guide 230, the ball receives at least a portion of the connecting portion 220 and the ball is in contact with the protrusion 221 of the connecting portion 220 serves to guide the elastic member 240 to be described later.
탄성부재(240)는, 탄성부재 가이드(230)에 외삽되어 일단은 탄성부재 가이드(230)에 지지되고 타단은 메인바디(250)의 내측에 구비되는 탄성부재 지지부(251)에 지지된다. 탄성부재 지지부(251)는 이동이 불가능한 부재이므로, 탄성부재(240)는 앞서 살핀바와 같이 공이 연결부(220)에 전방으로 밀어내는 탄성력을 제공한다. 공이 연결부(220)에 제공되는 탄성력은 개폐 공이(210)에도 전달되는바 탄성부재(240)가 개폐 공이(210)에 탄성력을 제공하는 것으로도 설명될 수 있다.The elastic member 240 is extrapolated to the elastic member guide 230 so that one end is supported by the elastic member guide 230 and the other end is supported by the elastic member support part 251 provided inside the main body 250. Since the elastic member support part 251 is a member that is not movable, the elastic member 240 provides an elastic force that pushes the ball forward to the connection part 220 like the salping bar. The elastic force provided to the ball connecting portion 220 is also transmitted to the opening and closing ball 210 bar elastic member 240 may be described as providing an elastic force to the opening and closing ball 210.
메인바디(250)는, 개폐부(200)의 외관을 형성하며 중공의 내부에는 개폐 공이(210), 공이 연결부(220), 탄성부재 가이드(230), 탄성부재(240), 및 에어 실린더 샤프트(260)를 수용한다. 메인바디(250)의 전방에는 분리 바디(170)가 나사 결합되며 후방에는 접시 스프링 수용부(292)가 결합된다.The main body 250 forms the appearance of the opening and closing portion 200, the inside of the hollow opening and closing ball 210, the ball connecting portion 220, elastic member guide 230, elastic member 240, and air cylinder shaft ( 260). Separation body 170 is screwed to the front of the main body 250 and the plate spring receiving portion 292 is coupled to the rear.
메인바디(250)의 내측에는 중앙을 향하여 돌출되어 상기 탄성부재(240)를 지지하는 탄성부재 지지부(251)가 구비된다.An inner side of the main body 250 is provided with an elastic member support part 251 protruding toward the center to support the elastic member 240.
탄성부재 지지부(251)는 탄성부재(240)의 일단을 지지하는 역할을 하며, 탄성부재 지지부(251)에 형성된 중공으로는 에어 실린더 샤프트(260)가 통과한다.The elastic member supporter 251 serves to support one end of the elastic member 240, and the air cylinder shaft 260 passes through the hollow formed in the elastic member supporter 251.
에어 실린더 샤프트(260)는, 메인바디(250)의 개폐 공기 유입구(30)를 통해 유입되는 공기의 압력에 의해 이동한다. The air cylinder shaft 260 moves by the pressure of the air flowing through the opening / closing air inlet 30 of the main body 250.
에어 실린더 샤프트(260)는, 도 2에 도시된 바와 같이 공기 접촉부(261) 및 샤프트축(262)을 포함할 수 있다.The air cylinder shaft 260 may include an air contact 261 and a shaft shaft 262 as shown in FIG. 2.
공기 접촉부(261)는, 개폐 공기 유입구(30)를 통해 유입되는 공기와 접촉하여 공기의 압력에 의해 이동되는 부분이다. 공기 접촉부(261)는, 일례로서 메인바디(250)의 내경에 대응하는 지름을 갖는 원판 형상일 수 있으나, 이에 제한되는 것은 아니며 개폐 공기 유입구(30)를 통해 유입되는 공기와 접촉하여 이동될 수 있는 어떠한 형상도 가능하다.The air contact part 261 is a part which is contacted with the air which flows in through the open / close air inlet 30, and is moved by the pressure of air. The air contact portion 261 may be, for example, a disk shape having a diameter corresponding to the inner diameter of the main body 250, but is not limited thereto. The air contact portion 261 may be moved in contact with air introduced through the opening / closing air inlet 30. Any shape is possible.
샤프트축(262)은, 공기 접촉부(261)의 중심에 구비되어 전방으로 연장형성된다. 따라서, 샤프트축(262)은 공기 접촉부(261)와 함께 이동한다. 또한, 샤프트축(262)의 말단은 공이 연결부(220)와 만난다. 이와 같은 구조를 통해, 공기 접촉부(261)가 이동하면 샤프트축(262)의 말단이 공이 연결부(220)를 이동시킬 수 있다.또한, 공이 연결부(220)는 개폐 공이(210)를 이동시켜 개폐공(175)을 개폐할 수 있다. 따라서, 에어 실린더 샤프트(260)는 개폐 공기 유입구(30)를 통해 유입되는 공기와 접촉하여 공기의 압력에 의해 개폐공(175)을 선택적으로 개폐하는 것으로 설명될 수 있다.The shaft shaft 262 is provided at the center of the air contact portion 261 and extends forward. Thus, shaft shaft 262 moves with air contact 261. In addition, the end of the shaft shaft 262, the ball meets the connecting portion (220). Through this structure, when the air contact portion 261 is moved, the end of the shaft shaft 262 can move the ball connecting portion 220. In addition, the ball connecting portion 220 is opened and closed by moving the opening and closing ball 210 The ball 175 can be opened and closed. Therefore, the air cylinder shaft 260 may be described as selectively opening and closing the opening and closing hole 175 by the pressure of the air in contact with the air flowing through the opening and closing air inlet 30.
에어 실린더 샤프트(260)의 후방에는 에어 실린더 샤프트 고정 너트(260)가 구비되며, 에어 실린더 샤프트(260)의 후단은 접시 스프링(290)에 의해 탄성 지지된다.An air cylinder shaft fixing nut 260 is provided at the rear of the air cylinder shaft 260, and the rear end of the air cylinder shaft 260 is elastically supported by the disc spring 290.
에어 실린더 샤프트 고정 너트(270)는, 에어 실린더 샤프트(260)의 움직임을 전후 방향 움직임으로 제한하기 위해 에어 실린더 샤프트(260)의 후단에 구비된다. 에어 실린더 샤프트 고정 너트(270)는 일례로서 홀을 포함하며, 상기 홀에 에어 실린더 샤프트(260)의 돌출된 부분이 삽입되는 형식으로 에어 실린더 샤프트 고정 너트(270)가 에어 실린더 샤프트(260)에 고정될 수 있다.The air cylinder shaft fixing nut 270 is provided at the rear end of the air cylinder shaft 260 to limit the movement of the air cylinder shaft 260 to forward and backward movement. The air cylinder shaft fixing nut 270 includes a hole as an example, and the air cylinder shaft fixing nut 270 is inserted into the air cylinder shaft 260 in such a way that a protruding portion of the air cylinder shaft 260 is inserted into the hole. Can be fixed.
스냅링(280)은, 후술할 접시 스프링(290)이 접시 스프링 수용부(292)에서 전방으로 이탈되는 것은 방지하기 위해 구비된다.The snap ring 280 is provided to prevent the plate spring 290, which will be described later, from moving forward from the plate spring receiving unit 292.
접시 스프링(290)은, 에어 실린더 샤프트(260)의 후방에 구비되어 에어 실린더 샤프트(260)에 탄성력을 제공한다. 접시 스프링(290)의 일단은 접시 스프링 수용부(292)에 의해 지지되며, 접시 스프링(290)의 타단은 접시 스프링 고정부(291)에 지지된다. 접시 스프링 고정부(291)는 전후 방향으로 유동가능한 부재로써 에어 실린더 샤프트(260)에 이동력을 제공한다. 따라서, 접시 스프링(290)은 에어 실린더 샤프트(260)에 탄성력을 제공하는 것으로도 설명될 수 있다.The disc spring 290 is provided at the rear of the air cylinder shaft 260 to provide elastic force to the air cylinder shaft 260. One end of the dish spring 290 is supported by the dish spring receiving portion 292, and the other end of the dish spring 290 is supported by the dish spring fixing portion 291. The disc spring fixed portion 291 is a member movable in the front-rear direction to provide a moving force to the air cylinder shaft 260. Thus, the disc spring 290 may also be described as providing an elastic force to the air cylinder shaft 260.
접시 스프링(290)은, 외압이 없는 상태에서 에어 실린더 샤프트(260)에 전방으로 미는 힘을 제공한다. 따라서, 에어 실린더 샤프트(260)와 연결된 공이 연결부(220), 및 공이 연결부(220)와 연결된 개폐 공이(210)도 전방으로 밀려 개폐공(175)이 닫힌 상태로 유지되는 것이다. 다만, 개폐 공기 유입구(30)로 공기가 유입되어 에어 실린더 샤프트(260)의 공기 접촉부(261)를 후방으로 밀면 접시 스프링(290)이 압축되어 공이 연결부(220) 및 개폐 공이(210)도 후방으로 이동가능한 상태가 되는 것이다.The disc spring 290 provides a force to push the air cylinder shaft 260 forward in the absence of external pressure. Therefore, the ball connected to the air cylinder shaft 260 is connected to the connection part 220, and the opening and closing ball 210 is connected to the connection part 220 is also pushed forward to maintain the opening and closing hole 175 is closed. However, when the air is introduced into the open / close air inlet 30 and pushes the air contact portion 261 of the air cylinder shaft 260 backward, the disc spring 290 is compressed so that the ball connection part 220 and the open / close ball 210 are also rearward. It becomes the state which can move to.
본 발명에서는, 에어 실린더 샤프트(260)의 후방에 코일 스프링이 아닌 접시 스프링(290)이 사용되는데, 이 경우 본 발명의 보텍스 코팅건을 장시간 사용하는 경우, 즉 접시 스프링(290)이 장시간 압축 상태로 유지되는 경우에도 코일 스프링에 비하여 복원력이 감소하지 않는 장점이 있다.In the present invention, the dish spring 290 is used in the rear of the air cylinder shaft 260, not the coil spring, in which case the vortex coating gun of the present invention is used for a long time, that is, the dish spring 290 is compressed for a long time Even when maintained as, there is an advantage that the restoring force is not reduced compared to the coil spring.
접시 스프링 고정부(291)는, 접시 스프링(290)의 전방에 구비되어 접시 스프링(290)을 고정하며 스냅링(280)에 의해 전방으로의 움직임이 제한된다.The dish spring fixing part 291 is provided in front of the dish spring 290 to fix the dish spring 290 and the movement forward is limited by the snap ring 280.
접시 스프링 수용부(292)는, 접시 스프링(290), 접시 스프링 고정부(291), 및 스냅링(280)을 내부에 수용하며 외관을 형성한다.The dish spring receiving portion 292 accommodates the dish spring 290, the dish spring fixing portion 291, and the snap ring 280 therein, and forms an appearance.
개폐량 조절부(300)는, 분사부(100)를 통해 분사되는 코팅액의 양을 조절하는 역할을 한다. The opening / closing amount adjusting unit 300 serves to adjust the amount of the coating liquid sprayed through the spraying unit 100.
개폐량 조절부(300)는, 일례로서 도 2에 도시된 바와 같이 마이크로미터 고정블럭(310), 마이크로미터(320), 및 마이크로미터 고정너트(330)를 포함할 수 있다.The opening and closing amount adjusting unit 300 may include, for example, a micrometer fixing block 310, a micrometer 320, and a micrometer fixing nut 330 as shown in FIG. 2.
마이크로미터 고정블럭(310)은, 후술할 마이크로미터(320)를 회전 가능하게 고정하는 역할을 한다.The micrometer fixing block 310 serves to rotatably fix the micrometer 320 to be described later.
마이크로미터(320)는, 에어 실린더 샤프트(260)의 후방에 위치하며 회전에 의해 전후 방향으로 이동되어 에어 실린더 샤프트(260)의 이동 가능 거리를 제한하는 역할을 한다.The micrometer 320 is positioned at the rear of the air cylinder shaft 260 and moved in the front-rear direction by rotation to limit the movable distance of the air cylinder shaft 260.
마이크로미터 고정너트(330)는, 마이크로미터(320)의 후방에 삽입되어 마이크로미터(320)를 회전 가능하게 고정한다.The micrometer fixing nut 330 is inserted into the rear of the micrometer 320 to fix the micrometer 320 to be rotatable.
이하에서는 본 발명의 일례에 따른 보텍스 코팅건의 작동을 도면을 참조하여 상세하게 설명한다.Hereinafter will be described in detail with reference to the operation of the vortex coating gun according to an example of the present invention.
도 3은 본 발명의 일례에 따른 보텍스 코팅건을 도시하는 단면도이다.3 is a cross-sectional view showing a vortex coating gun according to an example of the present invention.
또한, 도 4의 (a)는 본 발명의 일례에 따른 보텍스 코팅건이 니들 코팅건으로 기능하도록 코팅액을 도포하는 모습을 도시한 것이며, 도 4의 (b)는 본 발명의 일례에 따른 보텍스 코팅건이 멤브레인 코팅건으로 기능하도록 코팅액을 도포하는 모습을 도시한 것이다.In addition, Figure 4 (a) shows the appearance of coating the coating solution so that the vortex coating gun according to an example of the present invention functions as a needle coating gun, Figure 4 (b) is a membrane vortex coating gun according to an example of the present invention The coating liquid is applied to function as a coating gun.
도 3를 참조하면, 본 발명의 일례에 따른 보텍스 코팅건은, 사용 전 단계에서는 에어 실린더 샤프트(260)가 접시 스프링(290)의 탄성력에 의해 전방으로 밀리는 힘을 받고 있는 상태이며, 에어 실린더 샤프트(260)와 연결된 공이 연결부(220) 및 개폐 공이(210)에도 상기 탄성력이 전달되고 있는 상태이다. 따라서, 개폐 공이(210)가 개폐공(175)을 닫고 있는 상태이다.Referring to FIG. 3, the vortex coating gun according to an example of the present invention is a state in which the air cylinder shaft 260 is pushed forward by the elastic force of the disc spring 290 in a pre-use step, and the air cylinder shaft The ball connected to 260 is a state in which the elastic force is also transmitted to the connecting portion 220 and the opening and closing ball 210. Accordingly, the opening and closing ball 210 is in a state of closing the opening and closing hole 175.
이때에는, 코팅액 유입구(10)를 통해 코팅액(40)이 유입(a)되더라도 개폐 공이(210)에 의해 개폐공(175)이 닫힌 상태이므로 코팅액(40)이 주사기(140)로 공급될 수 없다.At this time, even if the coating liquid 40 is introduced (a) through the coating liquid inlet 10, the coating liquid 40 may not be supplied to the syringe 140 because the opening and closing hole 175 is closed by the opening and closing ball 210. .
개폐 공기 유입구(30)에 공기가 일정 압력이상으로 공급(b)되면, 개폐 공기 유입구(30)를 통해 유입된 공기가 에어 실린더 샤프트(260)의 공기 접촉부(261)를 후방으로 밀게 된다(c). 공기가 공기 접촉부(261)를 미는 힘이 접시 스프링(290)의 탄성력을 초과하게 되면 에어 실린더 샤프트(260)는 후퇴하게 된다. When the air is supplied to the open / close air inlet 30 at a predetermined pressure or more (b), the air introduced through the open / close air inlet 30 pushes the air contact portion 261 of the air cylinder shaft 260 backward (c). ). The air cylinder shaft 260 retracts when the force that air pushes the air contact 261 exceeds the elastic force of the disc spring 290.
따라서, 에어 실린더 샤프트(260)의 전방에 위치하는 공이 연결부(220) 및 개폐 공이(210)도 후퇴할 수 있는 상황이 된다. 그러나, 코팅액 유입구(10)를 통해 코팅액(40)이 유입되고 있는 상황이 아니라면 탄성부재(240)에 의해 공이 연결부(220)가 탄성 지지되고 있어 후퇴하지 않게 된다. 즉, 에어 실린더 샤프트(260) 및 공이 연결부(220)는 이격되게 된다. 이와 같이, 코팅액 유입구(10)를 통한 코팅액(40)의 유입이 없는 경우에는 공이 연결부(220) 및 개폐 공이(210)가 개폐공(175)을 막고 있으므로 개폐공(175)으로 이물질이 유입되는 현상을 방지하는 장점이 있다.Therefore, the ball located in front of the air cylinder shaft 260 is a situation that the connection portion 220 and the opening and closing ball 210 can also retreat. However, if the coating liquid 40 is not introduced through the coating liquid inlet 10, the ball connecting portion 220 is elastically supported by the elastic member 240 so as not to retreat. That is, the air cylinder shaft 260 and the ball connecting portion 220 is spaced apart. As such, when there is no inflow of the coating liquid 40 through the coating liquid inlet 10, the ball is connected to the opening 220 and the opening and closing ball 210 so that the foreign matter is introduced into the opening and closing hole 175. There is an advantage to prevent the phenomenon.
