* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

본 고안은 소형용접물을 용접하기에 적합한 전기 저항 용접기의 회로에 관한 것으로서 특히 자동정타기용 못을 철선에 고속으로 연속 용접하기에 가장 적합 하도록 한 것이다.The present invention relates to a circuit of an electric resistance welder suitable for welding small welds, and is particularly suitable for continuous welding of high speed nails to wires.

일반적으로 전기저항 용접은 대전류를 단시간에 흘러 줄 필요가 있으며 종래,이에 대한 방법으로서 콘덴서 충전식의 용접기가 사용되었으나 이는 콘덴서 충전시간이 소요되므로 고속 용접이 불가능하고 콘덴서 수명상의 문제로 인하여 장시간 연속 사용이 곤란한 결점이 있었으며 공개특허번호 제83-7200호와 같이 트랜지스터를 브리지 접속하여 정류된 직류전압을 인가하는 인버터 제어형 용접기도 있었으나 이는 트랜지스터를 교호로 동작시키기 위한 구동회로. 제어뢰로 및 플립플롭회로 등의 부가회로가 필요하게 되어 구조가 복잡한 등의 단점이 있었다.In general, the electric resistance welding needs to flow a large current in a short time. Conventionally, as a method for this, a capacitor-type welding machine is used. However, since it takes a long time to charge the capacitor, high-speed welding is not possible, and it is difficult to use it continuously for a long time due to problems in the life of the capacitor. There was an inconvenient drawback, and there was an inverter-controlled welding machine which applied rectified DC voltage by bridge-connecting transistors as disclosed in Korean Patent No. 83-7200, but this is a driving circuit for operating transistors alternately. An additional circuit such as a control furnace and a flip-flop circuit is required, which has a disadvantage in that the structure is complicated.

또한 용접물의 위치를 검출함에 있어서도 종래의 간접식 위치 검출방식은 용접물과 위치검출장치의 상대위치 관계를 일치시키기 위한 타이머회로에 의해 용접 전류를 통전 제어해야 하고 타이머회로를 정밀 조정해야 하거나 기계적 오차에 의한 불일치상의 문제점이 있었다.In addition, in detecting the position of a weldment, the conventional indirect position detection method requires energizing and controlling the welding current by a timer circuit for matching the relative positional relationship between the weldment and the position detection device, and requires precise adjustment of the timer circuit or mechanical error. There was a problem of inconsistency.

본 고안은 이러한 제반 문제점을 해결하기 위하여 병렬 접속된 S.C.R을 위상제어회로에 의하여 용접전류를 제어하고 용접물의 위치를 직접 검출하도록 구성한 것으로서 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is configured to control the welding current by the phase control circuit to the S.C.R connected in parallel in order to solve these problems as described in detail by the accompanying drawings as follows.

"제1도" 에서와 같이 S. C. R(1)(2)을 역방향으로 병렬 접속하여 용접변압기(3)의 1차권선을 통하여 교류전원에 접속하고 감지회로(5)와 터언오프회로(6)의 신호에 의해 제어 동작되는 위상제어회로(4)의 출력은 S.C.R(1)(2)의 게이트(G1)(G2)에 각각 접속하였다.As shown in FIG. 1, SC R (1) 2 is connected in parallel in the reverse direction, connected to the AC power supply through the primary winding of the welding transformer 3, and the sensing circuit 5 and the turn-off circuit 6 are connected. The output of the phase control circuit 4 which is controlled and operated by the signal of is connected to the gates G 1 and G 2 of the SCR 1 and 2 , respectively.

위상제어회로(4)는 감지회로(5)와 터언오프회로(6)의 신호에 의해 S.C.R(1)(2)을 터언 온 또는 터언 오프함과 동시에 용접전류를 제어한다.The phase control circuit 4 turns on or off the S.C.R (1) 2 by the signals of the sensing circuit 5 and the turn-off circuit 6 and simultaneously controls the welding current.

감지회로(5)는 통상의 수광감지방법에 의해 용접물을 감지하고 그 신호는 위상제어회로(4)와 터언 오프 회로(6)를 동작 시킨다.The sensing circuit 5 detects the weld by a conventional light receiving sensing method, and the signal operates the phase control circuit 4 and the turn off circuit 6.

터언오프 회로(6)는 타이머회로로서 감지회로(5)의 신호가 입력된 후 일정시간 후에 S.C.R(1)(2)을 터언오프시켜 용접전류를 차단한다.The turn-off circuit 6 turns off the S.C.R (1) 2 after a predetermined time after the signal of the sensing circuit 5 is input as a timer circuit to cut off the welding current.

"제2도"는 본고안 실시예의 구성도로서 외주면에 홈(8')이 종설된 원판(8)은 모터(도시안됨)에 의하여 회동되고 못(7)은 슈우트(9)로부터 공급되어 홈(8')에 삽설된다.FIG. 2 is a block diagram of the present embodiment, in which a disc 8 having a groove 8 'formed on its outer circumference is rotated by a motor (not shown), and a nail 7 is supplied from the chute 9. It is inserted into the groove 8 '.

철선(12)은 공급기에 의해 못(7)의 외측에 공급된다.The iron wire 12 is supplied to the outside of the nail 7 by a feeder.

로울러 전극(10)(11)에는 용접변압기(3)의 2차권선에 접속되어 있으며 원판(8)의 측면에 맞닿아 회동하면서 못(7)과 철선(12)을 저항 용접하게 되는 것이다.The roller electrodes 10 and 11 are connected to the secondary windings of the welding transformer 3, and the nails 7 and the iron wires 12 are resistance-welded while being rotated in contact with the side surfaces of the disc 8.

이와같이 구성된 본 고안은 슈우트(9)로 부터 공급된 못(7)이 원판(8)의 홈(8')에 삽설되고 원판(8)이 회동하여서 로울러 전극(10)(11)에 못(7)이 접근하게 되면 감지회로(5)는 못(7)이 지나갈때 마다 계속해서 신호를 송출하게 되고 감지회로(5)의 신호는 위상 제어회로(4)를 동작시키며 위상제어 회로(4)의 신호는S.C.R(1)(2)의 게이트(G1)(G2)에 인가되어 트리거 신호로 작용한다.According to the present invention, the nail (7) supplied from the chute (9) is inserted into the groove (8 ') of the disc (8) and the disc (8) is rotated so that the nail (10) (11) When 7) approaches, the sensing circuit 5 continuously transmits a signal each time the nail 7 passes, and the signal of the sensing circuit 5 operates the phase control circuit 4, and the phase control circuit 4 Is applied to the gate (G 1 ) (G 2 ) of the SCR (1) (2) to act as a trigger signal.

따라서 S.C.R(1)(2)은 터언 온 되어 용접변압기(3)의 1차권선에 교류전원이 인가된다.Therefore, the S.C.R (1) (2) is turned on and the AC power is applied to the primary winding of the welding transformer (3).

위상제어회로(4)는 수동조작에 의해서 적절히 조정하므로서 용접전류를 제어하고 용접이 적절히 이루어지게 한다.The phase control circuit 4 adjusts the welding current appropriately by manual operation so that the welding is made properly.

한편 감지회로(5)의 신호는 터언 오프 회로(6)에도 인가되어 타이머로 구성된 터언오프 회로(6)를 동작시키게 되고 감지회로(5)의 신호가 인가되지 않으면 즉 못(7)의 공급이 중단되면 설정된 일정 시간후 S.C.R(1)(2)을 터언 오프 시켜 용접전류를 차단하게 된다.On the other hand, the signal of the sensing circuit 5 is also applied to the turn-off circuit 6 to operate the turn-off circuit 6 composed of a timer, and if the signal of the sensing circuit 5 is not applied, that is, the supply of the nail 7 If interrupted, the welding current is cut off by turning off the SCR (1) (2) after a predetermined time.

이상과 같은 작용에 의하여 못의 공급 여부를 직접 검출함과 동시에 S.C.R(1)(2)을 터언 온 또는 터온 오프시키는 간단한 방법으르 대전류를 순간적으로 제어할뿐 아니라 위상제어회로에 의하여 용접전뮤를 제어함과 동시에 용접물이 용접점위에 위치할때만 용접전류가 공급되므로 장시간 동안 효율적인 용접이 연속 가능하게되는 것이다.With the above-mentioned action, it is possible to directly detect whether nails are supplied and to turn on or turn off SCR (1) (2). At the same time, the welding current is supplied only when the welding material is located on the welding point, so that efficient welding can be continuously performed for a long time.

따라서 본 고안은 구성이 매우 간편하면서도 보다 정확히 작동하며 고속으로 장시간 연속 용접이 가능한등의 효과가 있는 것이다.Therefore, the present invention is very easy to configure, but more precisely, it is possible to effect long time continuous welding at high speed.
