Abstract

A mask for a roller printer with a nozzle is provided to prevent the mask from being eroded due to an injection of a solder by arranging the nozzle made of a material with a high intensity on a solder injection hole. A mask(100) of a roller printer is implemented on a base(4). A PCB is implemented under the mask. A roller of the roller printer is slid to spray a solder on the PCB(Printed Circuit Board). The solder is sprayed on an accurate land position of the PCB, when a solder injection hole is compressed by the roller(6). A nozzle is inserted into the solder injection hole. The nozzle is made of a material with a higher intensity than the mask, so that the nozzle is not eroded, even when a large amount of solders are sprayed on the nozzle.

본 발명은 노즐이 설치된 롤러 인쇄기용 마스크에 관한 것으로, 보다 상세하게는 피시비(PCB)의 랜드(Land) 위치에 솔더(Solder)를 도포하기 위하여 롤러에 의 해 주입되는 솔더를 안내하도록 노즐이 설치됨으로써, 종래 마스크에 직접 형성된 솔드주입공의 확대에 의해 마스크 전체를 교체하여야 했던 문제점을 해소하고 마스크의 내구 수명을 증대시킨 노즐이 설치된 롤러 인쇄기용 마스크에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mask for a roller printing machine in which a nozzle is installed. More specifically, the nozzle is installed to guide solder injected by the roller in order to apply solder to a land position of a PCB. Accordingly, the present invention relates to a mask for a roller printing machine provided with a nozzle that solves the problem of having to replace the entire mask by enlarging the solder injection hole formed directly in the conventional mask and increasing the endurance life of the mask.

롤러 인쇄기는 PCB의 랜드 위치에 크림 형태의 가공용 납인 솔더를 도포하는 장치이다. 이와 같은 솔더는 롤러에 의해 마스크에 형성된 솔더주입공으로 방출되어, 마스크의 하부에 결합된 PCB의 랜드 위치에 정확하게 도포된다.The roller press is a device for applying a cream-type soldering solder to a land position of a PCB. This solder is discharged to the solder injection hole formed in the mask by the roller, and is accurately applied to the land position of the PCB bonded to the lower portion of the mask.

롤러는 마스크의 상부에서 이동되면서 솔더를 압출하여 솔더주입공을 통해 하부의 PCB로 보내게 되는데, 이 때 솔더가 압출되는 압력으로 인하여 마스크의 솔트주입공은 변형이 일어나게 된다.The roller is moved from the upper part of the mask to extrude the solder and send it to the lower PCB through the solder injection hole. At this time, the salt injection hole of the mask is deformed due to the pressure from which the solder is extruded.

따라서 계속되는 솔더의 압출에 의하여 솔더주입공은 점차 넓어지게 되고, 이로 인하여 제조된 PCB 상의 회로가 정확하게 형성되지 못하여 단락되는 현상까지 일어나게 된다. 그리고 이로 인하여 종래의 경우는 마스크의 수 많은 솔더주입공 중 어느 하나라도 손상이 생기면 전체 마스크를 교체하여야 하는 손실이 있었다.Therefore, the solder injection hole gradually widens due to the continuous extrusion of the solder, which causes a short circuit due to the inability to form a circuit on the manufactured PCB. And because of this, in the conventional case, if any one of the many solder injection holes of the mask is damaged, there is a loss to replace the entire mask.

본 발명의 목적은 상기와 같은 종래의 문제점을 해소하고자 함에 있는 것으로, 계속되는 솔더의 압출 압력에도 솔더주입공의 변형을 방지하여 PCB 상의 회로가 정확하게 형성될 수 있도록 함에 있다. 이를 위하여 본 발명은 솔더주입공에 별도로 제작된 강도 높은 노즐이 삽입된 구조의 마스크를 제공함에 구체적인 목적이 있다.An object of the present invention is to solve the conventional problems as described above, to prevent the deformation of the solder injection hole even in the extrusion pressure of the solder so that the circuit on the PCB can be formed accurately. To this end, the present invention has a specific purpose to provide a mask having a structure in which a high-strength nozzle is separately inserted into the solder injection hole.

이하 본 발명의 구성 및 작용을 첨부 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 솔더주입공(1)이 다수개 형성된 마스크(100)에 있어서, 상기 솔더주입공(1)에 솔더(2)가 압출되는 노즐(3)이 교체 가능하게 설치됨을 특징으로 한다.The present invention is characterized in that in the mask (100) having a plurality of solder injection holes (1), the nozzle (3) in which the solder (2) is extruded in the solder injection hole (1) is installed to be replaceable.

상기의 노즐(3)은 원통형으로서 상부와 하부의 외경이 다르게 형성되어 단턱이 형성된 구조이고, 솔더주입공(1)에 체결시 상기 단턱이 걸려 하중을 지지할 수 있는 구조로 되어 있다.The nozzle 3 is cylindrical and has a structure in which upper and lower outer diameters are formed to be different from each other, and has a stepped structure. When the nozzle 3 is fastened to the solder injection hole 1, the nozzle 3 is supported to support a load.

물론 본 발명의 노즐(3)은 마스크(100)의 재질보다 높은 강도를 가지는 것이 바람직하다.Of course, the nozzle 3 of the present invention preferably has a higher strength than the material of the mask 100.

이와 같은 구조를 가진 본 발명은 도 1에 일반적인 롤러 인쇄기가 도시되어 있고, 도 2에 본 발명의 특징인 노즐(3)이 설치된 마스크(100)가 도시되어 있으며, 도 3에 노즐(3)이 설치된 부분의 상세 단면도가 도시되어 있다.In the present invention having such a structure, a general roller printing machine is illustrated in FIG. 1, a mask 100 in which a nozzle 3 is installed in FIG. 2, and a nozzle 3 is illustrated in FIG. 3. A detailed cross section of the installed part is shown.

도 1에서와 같이 롤러 인쇄기에서는 베이스(4)의 상부에 마스크(100)가 설치되고, 마스크(100)의 하부에는 PCB(5)가 설치된다. 롤러 인쇄기의 롤러(6)는 도 3에 도시된 바와 같이 구름운동을 하면서 솔더(2)를 하부에 설치된 PCB(5)로 압출하게 된다.In the roller printing machine as shown in FIG. 1, a mask 100 is installed on an upper portion of the base 4, and a PCB 5 is installed on a lower portion of the mask 100. The roller 6 of the roller printing machine extrudes the solder 2 to the PCB 5 installed at the bottom while rolling in the rolling motion as shown in FIG. 3.

솔더(2)는 마스크(100)에 형성된 솔더주입공(1)을 롤러(6)에 의해 압출되면 서, PCB(5)상의 랜드 위치에 정확하게 도포된다. 이때 본 발명은 솔더(2)가 노즐(3)을 통하여 압출됨에 특징이 있다. 즉, 솔더주입공(1)에는 노즐(3)이 삽입되어 있고, 노즐(3)은 통상의 마스크(100)의 재질보다 높은 강도를 가지고 있으므로, 많은 솔더(2)의 압출이 이루어지더라도 노즐(3)의 내부가 마모되지 않게 된다. 그리고 솔더(2)에 의해 노즐(3)에 마모가 일어나더라도 노즐(3)의 내부에서 일어나게 되므로, 마스크(100)를 교체하여야 하는 문제는 없된다.The solder 2 is accurately applied to the land position on the PCB 5 while the solder injection hole 1 formed in the mask 100 is extruded by the roller 6. At this time, the present invention is characterized in that the solder (2) is extruded through the nozzle (3). That is, since the nozzle 3 is inserted into the solder injection hole 1 and the nozzle 3 has a higher strength than the material of the normal mask 100, even if a lot of solder 2 is extruded, the nozzle The inside of (3) is not worn. And even if abrasion occurs in the nozzle 3 by the solder (2) is generated inside the nozzle 3, there is no problem that the mask 100 must be replaced.

그리고 노즐(3)이 손상되어 교체를 하여하 하는 경우는 문제가 발생된 노즐만을 교체하면 되므로, 전체 마스크(100)를 교체하여야 하는 손실은 방지하게 된다.When the nozzle 3 is damaged and replaced, only a nozzle having a problem needs to be replaced, so that the loss of replacing the entire mask 100 is prevented.

또한 노즐(3)은 상하 외경이 다르게 형성된 단턱이 형성되는데, 이러한 단턱은 도 3의 확대부분에서와 같이 아래로 누를 경우 노즐(3)이 상부로 올라가는 것을 방지하게 된다.In addition, the nozzle 3 is formed with a stepped upper and lower outer diameter is formed, this step prevents the nozzle 3 to rise to the top when pressed down as in the enlarged portion of FIG.

이와 같은 구조에 의하여 솔더(2)에 의한 마스크(100)의 마모가 방지되고, 단턱의 구조에 의하여 상부에사 하부로 힘이 가해지더라도 노즐(3)이 빠지지 않게 된다.Such a structure prevents abrasion of the mask 100 by the solder 2, and the nozzle 3 does not fall even when a force is applied to the upper and lower portions by the stepped structure.

이와 같이 본 발명은 마스크(100)의 솔더주입공(1)에 마스크(100)보다 강도가 높은 재질로 된 노즐(3)이 설치됨으로써, 솔더(2)의 주입에 의한 종래의 마스크(100) 마모가 방지되고, 이로 인하여 정확하게 솔더(2)가 PCB(5)의 랜드에 도포 되며, 마모된 노즐(3)만을 교치하면 되므로 전체 마스크(100)의 교체에 따른 손실을 방지할 수 있게 된다.As described above, according to the present invention, a nozzle 3 made of a material having a higher strength than that of the mask 100 is installed in the solder injection hole 1 of the mask 100, thereby providing a conventional mask 100 by injecting solder 2. Abrasion is prevented, and thus, the solder 2 is precisely applied to the land of the PCB 5, and only the worn nozzles 3 need to be interposed, thereby preventing loss due to replacement of the entire mask 100.
