본 고안은 프린터에 사용되는 도트 매트릭스 헤드(Dot matrics head)에 관한 것으로서 스프링빔(Spring Beam)의 체결을 용이하게 하며 외부에서 스프링빔의 작동각도를 조절할 수 있도록 구조를 개량한 것이다.The present invention relates to a dot matrix head (Dot matrics head) used in the printer to facilitate the fastening of the Spring Beam (Spring Beam) and improved structure to adjust the operating angle of the spring beam from the outside.
종래의 매트릭스 헤드는 스프링빔의 체결을 위해 나사를 이용하거나 스프링빔을 일정각도 밴딩(Bending)하여 일체로 조립하는 경우가 있었다. 이러한 경우 스프링 빔이 지속적으로 오래 작업하게 되면 밴딩부위가 피로강도가 감소하게 되어 밴딩부위에 균열이 생겨 파괴되는 경우가 발생하게 되며 또한 조립후에는 프린트핀의 스트로크를 조절하기가 매우 어려워 양산성이 매우 저조하였으며 조립후 프린트핀의 스트로크가 일정 범위의 허용한도를 벗어나게 되면 이를 조절할 수 있는 방법이 없으므로 분해하여 처음부터 다시 조립해야 하므로 생산성이 매우 저조하였으므로 원가 상승의 요인이 되었다.Conventional matrix heads have been assembled integrally by using screws for fastening the spring beam or by bending the spring beam at an angle. In this case, if the spring beam continues to work for a long time, the bending area will be reduced in fatigue strength, causing cracking and breaking at the bending area, and it is very difficult to adjust the stroke of the print pin after assembly. It is very low, and if the stroke of the print pin after assembly is out of the allowable range of a certain range, there is no way to adjust it, so it has to be disassembled and reassembled from the beginning.
본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로서, 스프링빔의 회전각도를 외부에서 조절할 수 있도록 하여 프린트핀의 스트로크를 세트 조립후 조절 가능하게 하여 인자기구의 정밀도를 향상시키고 생산성을 향상시킬 수 있도록 함을 본 고안의 목적으로 한다.The present invention was devised to solve the above problems, to adjust the rotation angle of the spring beam from the outside to enable the adjustment of the stroke of the print pin after assembling the set to improve the precision of the printing mechanism and improve the productivity It is the purpose of the present invention.
본 고안의 또 다른 목적은 고정판의 외곽에 소정각도의 경사면을 주어 스프링빔의 회전각도를 용이하게 얻도록 하여 스프링빔을 밴딩하지 않고 조립할 수 있도록 하여 스프링빔의 수명을 연장할 수 있으므로 제품의 신뢰성을 향상시킬 수 있도록 한다.Another object of the present invention is to give an inclined surface of a predetermined angle to the outer side of the fixing plate to easily obtain the rotation angle of the spring beam to be assembled without bending the spring beam to extend the life of the spring beam product reliability To improve.
상기와 같은 목적을 달성하기 위한 바람직한 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.When described in detail with reference to the accompanying drawings a preferred embodiment for achieving the above object as follows.
우선 제1도를 참조하여 본 고안의 구성을 설명하면 원통형의 메인베이스(1)의 내측중앙에는 프린트핀(2), 안내통공(3)을 갖는 안내구(4)를 홀더(5)를 이용하여 고정하게 되는데 이때 안내구(4)를 홀더(5)를 이용하여 고정하게 되는데 이때 안내구(4)는 외부에 형성된 돌기(6)가 홀더(5)에 형성된 고정홈(7)에 끼워지도록 하여 고정하고 일측에 형성된 코어(8)에는 코일(9)이 감긴 보빈(10)을 압입하여 고정시킨다.First, referring to FIG. 1, the structure of the present invention will be described. A holder 5 may be used as a guide pin 4 having a print pin 2 and a guide hole 3 in the inner center of the cylindrical main base 1. In this case, the guide 4 is fixed by using the holder 5, wherein the guide 4 is fitted into the fixing groove 7 formed in the holder 5. And the bobbin 10 wound around the coil 9 is pressed into the core 8 formed on one side.
이러한 상태에서 메인베이스(1)의 상면에 고정판(11)과 상면판(12)을 나사(13)를 이용하여 체결하게 되는데 이때에는 고정판(11)하면의 고정홈(14)을 메인베이스(1) 외곽에 형성된 돌기(15)에 끼워 조립하고 고정판(11) 상면의 스프링빔(16)이 고정되는 곳에서 θ°만큼의 경사면(22)을 주어 스프링빔(16)이 θ°만큼 경사지게 설치하여 θ링(17)을 이용하여 설치되게 되는데 이때 스프링빔 중간에 설치된 아마튜어(18)는 고정판(11)의 통공(19)을 통하여 상기 코어(8) 상면에 위치되도록 하고 끝단에는 프린트핀(2)을 용접하여 고정한다. 또한 상면판(12)에는 스프링빔(16)상단에 스프링빔(16)의 작동스트로크를 조절할 수 있도록 외주면이 나사로 된 스트로크조절기(20)를 설치하며 스트로크조절기(20) 하면에는 스프링빔의 충격을 완충할 수 있는 댐퍼(21)를 설치한다.In this state, the fixing plate 11 and the upper plate 12 are fastened to the upper surface of the main base 1 by using the screws 13. At this time, the fixing groove 14 of the lower surface of the fixing plate 11 is fixed to the main base 1. Assembled into the protrusion 15 formed on the outer side and the inclined surface 22 as much as θ ° in the place where the spring beam 16 of the upper surface of the fixing plate 11 is fixed to install the spring beam 16 inclined by θ ° It is installed using the θ ring 17, wherein the armature 18 installed in the middle of the spring beam is positioned on the upper surface of the core 8 through the through hole 19 of the fixing plate 11 and the print pin (2) at the end. ) By welding. In addition, the upper surface plate 12 is provided with a stroke controller 20 of the outer peripheral surface of the screw to adjust the operating stroke of the spring beam 16 on the top of the spring beam 16, the impact of the spring beam on the lower surface of the stroke controller (20) A damper 21 capable of buffering is installed.
이와 같이 구성된 본 고안의 작용 효과는 우선 코일(9)의 전원이 공급되지 않은 상태에서는 스프링빔(16)의 끝단이 0링(17)에 의해 눌려진 상태에서 고정판의 경사면(22)을 따라 θ°만큼의 경사져서 댐퍼(21)에 의해 지지되어 정지해 있게 된다.The effect of the present invention configured as described above is θ ° along the inclined surface 22 of the fixed plate in the state where the end of the spring beam 16 is pressed by the 0 ring 17 in the state that the power of the coil 9 is not supplied. As much as it is inclined, it is supported by the damper 21 and is stopped.
이러한 상태에서 도시하지 않은 별도의 도트 매트릭스 헤드 구동장치에 의해 코일(9)에 전류가 흐르게 되면 메인베이스(1)의 코어(8)는 자화되어 자기력이 발생하게 되며 이 자기력은 아마튜어(18)를 끌어 당기게 되어 코어(8)상부에 아마튜어(18)를 밀착시키게 된다.In this state, when a current flows in the coil 9 by a separate dot matrix head driving device (not shown), the core 8 of the main base 1 is magnetized to generate a magnetic force, which is the armature 18. At the top, the armature 18 is brought into close contact with the core 8.
즉 스프링빔(16)은 회전 중심점(A)를 중심으로 하향 방향으로 회전되어 프린트핀(2)을 일정거리만큼 하향으로 움직이게 되는데 이때 프린트핀(2)은 안내통공(3)에 안내되어 직선으로 하강하게 된다.That is, the spring beam 16 is rotated in a downward direction about the rotation center point A to move the print pin 2 downward by a predetermined distance, where the print pin 2 is guided to the guide hole 3 in a straight line. Will descend.
이러한 상태에서 코일(9)에 전류가 차단되면 코어(8)의 자기력이 상실되므로 아마튜어(18)는 스프링빔(16)의 탄성력에 의해 원상으로 복귀되는데 이때 복귀되는 스프링빔(16)은 상면판(12)에 설치된 댐퍼(21)에 의해 충격을 완화하여 리바운드 현상은 거의 억제된다.In this state, when the current is interrupted in the coil 9, the magnetic force of the core 8 is lost. Thus, the armature 18 is returned to its original state by the elastic force of the spring beam 16. At this time, the spring beam 16 is returned. Shock is alleviated by the damper 21 provided in the plate 12, and the rebound phenomenon is almost suppressed.
이와 같은 과정을 반복하여 프린트핀(2)의 상하 운동을 얻어내고 이를 이용하여 도트를 형성시킬 수 있으며 이 도트의 배열을 조합하여 문자 또는 기호 및 그래프를 그릴 수 있도록 한다.By repeating such a process, the vertical motion of the print pin 2 can be obtained and a dot can be formed using the same, and the arrangement of the dots can be combined to draw letters, symbols, and graphs.
상기한 바와 같이 본 고안에 의하면 고정판의 경사면에 의하여 스프링빔이 회전할 수 있는 각도를 가지므로 스프링빔을 구부리지 않아도 되므로 스프링빔의 응력분포를 균일하게 하므로 스프링빔의 수명을 연장할 수 있으며 0링에 의해 간단히 조립할 수 있으므로 작업능률을 향상시킬 수 있다. 또한 스프링빔을 조립한 상태에서 외부에서 스트로크조절기를 이용하여 스프링빔의 왕복거리를 조절할 수 있으므로 조립능률을 향상시킬 수 있는 효과가 있다.As described above, according to the present invention, since the spring beam is rotated by the inclined surface of the fixing plate, the spring beam does not need to be bent, so that the stress distribution of the spring beam is uniform, thereby extending the life of the spring beam. Can be easily assembled to improve work efficiency. In addition, as the spring beam is assembled, the reciprocating distance of the spring beam can be adjusted using a stroke controller from the outside, thereby improving the assembly efficiency.
