본 발명은 용접 시뮬레이터에 관한 것으로, 더욱 상세하게는, 가상으로 용접이 수행되는 모습을 실시간으로 작업자에게 보여주고, 실시간으로 용접작업시의 용접토치각,용접속도등 자신이 실시하고 있는 용접작업에 대한 구체적이고 객관적인 데이터를 확인하면서 훈련이 가능한 용접 시뮬레이터에 관한 것이다. The present invention relates to a welding simulator, and more particularly, to a worker in real time showing the state in which the welding is performed virtually, the welding torch angle, the connection diagram during the welding operation in real time, such as to the welding work carried out by oneself The present invention relates to a welding simulator that can be trained while checking specific and objective data.

일반적으로, 용접이란 접합하고자 하는 두 개 이상의 물체(주로 금속)의 접합부분에 존재하는 방해물질을 제거하여 결합시키는 과정이라고 할 수 있는데 주로 열로 두 금속을 용융시켜 이 작업을 수행하게 된다.In general, welding is a process of removing the interference substances present in the joints of two or more objects (mainly metals) to be joined to each other. This is mainly performed by melting two metals by heat.

이러한 용접작업은 일반적으로 열악한 작업환경에서 이루어 지는 것이 보통이다. 따라서 용접기술의 발달과 더불어 로봇기술이 발달함에 따라 다양한 용접작업 자동화 기술개발이 진행중이고 현장에서 이미 많은 자동용접장치가 사용되고 있는 현실이다.This welding work is usually done in a harsh working environment. Therefore, with the development of welding technology and the development of robot technology, the development of various welding work automation technology is in progress, and many automatic welding devices are already used in the field.

그러나, 아직까지도 용접작업 환경에 따라 작업자가 직접 용접하여야 하는 수동용접이 필요한 곳이 다수이다.However, there are still many places where manual welding is required to be welded directly by the operator according to the welding working environment.

수동용접은 작업자의 고도의 용접기술과 많은 경험을 요구하는 작업이다. 특히, 열악한 작업환경에서 고도의 정밀성까지 요하는 용접부재를 용접하는 경우에는 더욱 그러할 것이다.Manual welding is a task that requires the operator's advanced welding skills and experience. This is especially true when welding welding elements that require a high degree of precision in harsh working environments.

따라서, 용접 작업자들은 숙련된 용접기술을 익히기 위하여 많은 용접훈련을 할 필요가 있다. 그러나 실제 용접훈련의 경우, 작업자가 훈련시 실시하고 있는 용접작업에 대한 구체적이고 객관적인 용접상태에 대한 데이터없이 실시되는 경우가 많고 작업자의 육안 또는 치구를 사용하여 용접상태의 양호성을 판단하는 문제점이 있다.Therefore, welding workers need to perform a lot of welding training in order to learn a skilled welding technique. However, in the case of actual welding training, it is often performed without data on the specific and objective welding state of the welding work performed by the worker. .

또한, 용접 훈련의 반복 횟수가 증가할수록 훈련시 필요한 용접재료들의 소모량도 크게 증가하기 때문에 비용이 많이 드는 문제점도 발생한다. In addition, as the number of repetitions of welding training increases, the consumption of welding materials required for training also increases significantly, which causes costly problems.

본 발명은 상기와 같은 문제점들을 해결하기 위하여 안출된 것으로, 작업자가 자신이 실시하고 있는 용접작업에 대한 구체적이고 객관적인 데이터를 확인하면서 훈련하는 것이 가능하고 용접재료를 소모하지 않고도 용접훈련이 가능한 가상 용접환경을 제공하는 용접 시뮬레이터를 제공하는데 있다.The present invention has been made in order to solve the above problems, it is possible for the operator to train while checking the specific and objective data on the welding work that he is performing and virtual welding capable of welding training without consuming the welding material It is to provide a welding simulator that provides an environment.

It is realized by the welding simulator comprising a; display unit for displaying the shape of the weld bead in real time using the extracted weld bead data.

한편, 상기 감지부는 상기 용접토치와 용접부재와의 각도을 측정하는 각도측정부; 상기 용접토치의 궤적을 측정하는 궤적측정부를 포함하여 구성된다.On the other hand, the detection unit is an angle measuring unit for measuring the angle of the welding torch and the welding member; It comprises a trajectory measurement unit for measuring the trajectory of the welding torch.

그리고 상기 표시부는 상기 용접비드의 형상과 함께 용접속도 표시화면과 용접토치와 용접부재와의 각도를 나타내는 용접토치각 표시화면을 실시간으로 동시에 제공하는 것을 특징으로 한다.The display unit may simultaneously provide a welding speed display screen and a welding torch angle display screen indicating an angle between the welding torch and the welding member together with the shape of the welding bead.

이하, 본 발명의 바람직한 실시예를 첨부 도면을 참조하여 설명한다. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은, 본 발명에 따른 용접 시뮬레이션의 구성을 나타낸 블록도이다.1 is a block diagram showing the configuration of a welding simulation according to the present invention.

도 1에서 도시한 바와 같이, 본 발명에 따른 용접 시뮬레이션은 연습용 용접토치(10)와 상기 용접토치(10)에 설치되어 용접토치(10)의 움직임을 감지하는 감지부(20)와 사용자가 용접조건데이터를 입력하는 입력부(30)를 포함하며, 상기 감지부(20)에서 수신된 용접토치(10)의 위치데이터와 상기 입력부(30)에서 입력된 용접조건데이터를 신호처리하여 용접비드 데이터를 추출하는 제어부(40)와 상기 제어부(40)에서 추출된 용접비드 데이터를 이용하여 용접비드의 형상을 실시간으로 나타내는 표시부(50)를 포함하여 구성된 것을 특징으로 한다.As shown in Figure 1, the welding simulation according to the present invention is installed on the practice welding torch 10 and the welding torch 10, the sensing unit 20 for detecting the movement of the welding torch 10 and the user welds And an input unit 30 for inputting condition data, and processing the welding bead data by signal processing the position data of the welding torch 10 received from the sensing unit 20 and the welding condition data input from the input unit 30. It characterized in that it comprises a control unit 40 to extract and the display unit 50 to display the shape of the weld bead in real time using the weld bead data extracted from the control unit 40.

이하, 위와 같은 본 발명에 따른 용접 시뮬레이션의 일 실시예의 구성을 구체적으로 살펴본다.Hereinafter, the configuration of an embodiment of a welding simulation according to the present invention as described above will be described in detail.

도 2는, 본 발명에 따른 용접 시뮬레이션에서 사용되는 연습용 용접토치를 나타낸 사시도이다.Figure 2 is a perspective view showing a practice welding torch used in the welding simulation according to the present invention.

도 2에서 도시한 바와 같이, 연습용 상기 용접토치(10)는 무게나 크기등 실 제 용접작업에서 사용하는 용접토치와 동일한 것으로 구성하여 작업자의 용접훈련의 효과를 극대화하는 것이 바람직하다.As shown in Figure 2, the welding torch 10 for practice is preferably configured to be the same as the welding torch used in the actual welding work, such as weight or size, to maximize the effect of the welding training of the operator.

또한, 용접부재도 작업자가 실제 용접작업을 수행해야 하는 용접부재의 시편(W:LNG탱크의 멤브레인)을 마련하는 것이 좋다. In addition, the welding member is also good to prepare a specimen (W: membrane of the LNG tank) of the welding member that the operator should perform the actual welding work.

다만 상기 용접토치(10)는 실제 용접작업에서 쓰이는 용접토치와 달리 내부에 상기 용접토치의 움직임을 감지하는 센서들로 이루어진 감지부(20)가 설치된다.However, the welding torch 10, unlike the welding torch used in the actual welding operation, the sensor 20 is formed of a sensor 20 for detecting the movement of the welding torch inside.

상기 감지부(20)는 상기 용접토치(10)와 용접부재와의 각도을 측정하는 각도센서(21)가 상기 용접토치(10)의 손잡이부분에 설치되고, 상기 용접토치(10)의 궤적을 측정하는 광센서(22)가 상기 용접토치(10)의 끝단에 설치되는 것을 특징으로 한다.The sensing unit 20 is an angle sensor 21 for measuring the angle between the welding torch 10 and the welding member is installed on the handle portion of the welding torch 10, and measures the trajectory of the welding torch 10. The optical sensor 22 is characterized in that it is installed at the end of the welding torch 10.

일반적으로, 용접토치와 용접부재가 이루는 용접토치각은 용접작업중 용착금속의 용착위치와 용입방향을 결정하는 중요한 요소이다.In general, the welding torch angle formed by the welding torch and the welding member is an important factor in determining the welding position and welding direction of the weld metal during the welding operation.

즉, 용접토치각에 따라 용접비드(weld bead)의 크기나 형상이 달라지기 때문에 작업자가 연습용 상기 용접토치(10)를 가지고 용접연습을 할 때 실시간으로 용접토치각을 측정하여야 한다.That is, because the size or shape of the weld bead (weld bead) varies depending on the welding torch angle, the welding torch angle should be measured in real time when the worker exercises the welding torch 10 for practice.

이를 위해서 1축 각도센서(21)가 상기 용접토치(10)의 손잡이 부분에 설치된다.To this end, the one-axis angle sensor 21 is installed in the handle portion of the welding torch 10.

여기서 용접비드(weld bead)란 아크용접시 모재와 용접봉을 전기열로 용접할때 용접진행방향으로 생기는 이음부를 용접비드라고 한다. Here, the weld bead (weld bead) is called a weld bead that is generated in the welding direction when welding the base material and the electrode by electric heat during arc welding.

한편, 상기 용접토치(10)의 궤적을 측정하기 위하여 광센서(22)가 상기 용접 토치(10)의 끝단에 설치된다.On the other hand, in order to measure the trajectory of the welding torch 10, an optical sensor 22 is installed at the end of the welding torch 10.

이는 용접토치(10)의 궤적을 측정하여 작업자의 용접속도를 파악하고, 용접선을 따라 용접이 제대로 되었는지를 디스플레이 하기 위함이다.This is to determine the welding speed of the operator by measuring the trajectory of the welding torch 10, and to display whether the welding is properly along the welding line.

작업자의 용접속도는 앞서 언급한 용접토치각과 마찬가지로 용접비드의 크기나 형상을 결정하는 중요한 요소이기 때문에 이를 파악하는 것이 중요하다.It is important to know the welding speed of the worker because it is an important factor that determines the size and shape of the welding bead, as mentioned above.

상기 입력부(30)는 작업자가 용접조건데이터를 작업환경에 맞게 입력하는 부분이다. 작업자가 직접 입력하는 용접조건데이터는 부재종류(Corrugation Type) 용접자세(Floor, Horizontal, Vertical, Overhead)등이 있다.The input unit 30 is a part in which an operator inputs welding condition data according to a working environment. The welding condition data input by the operator directly include the corrugation type welding posture (Floor, Horizontal, Vertical, Overhead).

도 3은, 본 발명에 따른 용접 시뮬레이터의 입력부에서 나타낸 코루게이션의 크기와 용접자세를 선택할 수 있는 메뉴화면을 나타낸 그림이다.3 is a view showing a menu screen for selecting the size and the welding posture of the corrugation shown in the input unit of the welding simulator according to the present invention.

한편, 위와 같은 용접조건데이터외에 작업자는 코루게이션의 크기와 용접자세를 선택하여 입력할 수 있다. 용접자세에 따라 용접비드의 크기나 형상이 달라질 수 있기 때문에 도 3에서 도시한 바와 같이, 용접할 부분의 위치에 따라 취하여야 할 작업자세를 선택할 수 있는 용접자세 선택메뉴(P)를 작업자에게 제공한다.On the other hand, in addition to the above welding condition data, the operator can select and input the size and welding position of the corrugation. Since the size or shape of the welding bead may vary depending on the welding posture, as shown in FIG. do.

일 실시예의 경우, LNG탱크의 멤브레인을 용접부재로 선택하였기 때문에 멤브레인 용접에 필요한 4가지 방향에서의 용접자세를 선택하여 입력할 수 있다.In the exemplary embodiment, since the membrane of the LNG tank is selected as the welding member, the welding posture in four directions necessary for the welding of the membrane may be selected and input.

코루게이션(CORRUGATION)의 크기 선택메뉴(C)에서는 멤브레인에 형성되어 있는 코루게이션의 크기에 따라 2가지로 분류하여 선택할 수 있다.In the size selection menu (C) of the corrugation (CORRUGATION) can be classified into two types according to the size of the corrugation formed in the membrane.

멤브레인의 코루게이션 구간은 정확한 용접이 까다로운 곳으로 그 크기에 따라 용접비드의 형상과 크기가 다르게 나타나므로 코루게이션의 크기를 나누어 작업 자가 보다 효율적으로 용접작업을 가상으로 연습할 수 있도록 한다.Corrugation section of the membrane is a place where accurate welding is difficult, and the shape and size of the welding bead is different depending on the size, so that the operator can practice the welding work more efficiently by dividing the size of the corrugation.

한편, 상기 제어부(40)는 상기 1축 각도센서(21), 광센서(22),및 입력부(30)와 연결되어 이로부터 얻은 용접토치(10)의 위치데이터와 작업자가 입력한 전류값, 아르곤(Ar)가스량, 전극봉의 굵기등의 용접조건데이터등을 신호처리하여 용접비드의 형상을 디스플레이하기 위한 용접비드데이터를 추출한다.On the other hand, the controller 40 is connected to the one-axis angle sensor 21, the optical sensor 22, and the input unit 30, the position data of the welding torch 10 obtained therefrom and the current value input by the operator, The welding bead data for displaying the shape of the welding bead is extracted by signal processing the welding condition data such as the amount of argon (Ar) gas and the thickness of the electrode.

상기 제어부(40)는 용접 시뮬레이터의 휴대성을 고려하여 이동형 PC등이 사용되는 것이 바람직하다.The controller 40 is preferably a mobile PC in consideration of the portability of the welding simulator.

상기 표시부(50)는 상기 제어부(40)와 연결되어 상기 제어부(40)에서 추출한 용접비드 데이터를 이용하여 용접이 수행되는 용접부재상의 용접비드의 형상을 실시간으로 나타낸다.The display unit 50 is connected to the control unit 40 to represent the shape of the welding bead on the welding member to be welded using the welding bead data extracted by the control unit 40 in real time.

이하, 본 발명에 따른 일 실시예의 용접 시뮬레이터가 작동시 나타나는 표시부의 화면을 구체적으로 살펴본다.Hereinafter, the screen of the display unit that appears when the welding simulator of the embodiment of the present invention operates is described in detail.

Meanwhile, a weld bead shape display unit 53 is provided at the lower end of the weld data display unit 51 to provide an enlarged screen of a weld bead shape to a worker in real time. Through the weld bead shape display unit 53, the operator can more easily observe the shape of the weld bead 53a in real time.

상기 용접비드형상 표시부(53)를 통해 용접토치각에 따른 용접비드(53a)의 형상을 구체적으로 살펴보면, 도 4의 53a에서 도시한 바와 같이, 용접토치각이 90°일 때는 용접비드의 모양이 원형에 가깝다는 것을 알 수 있다. 그러나, 도 5의 53a, 도 6의 53a에서 도시한 바와 같이, 용접토치각이 각각 60°, 30°일 경우에는 용접비드의 모양이 점점 타원형에 가까워짐을 알 수 있다.

However, as shown in 53a of FIG. 5 and 53a of FIG. 6, when the welding torch angles are 60 ° and 30 °, respectively, it can be seen that the shape of the welding bead becomes closer to an ellipse.

그리고 상기 용접비드형상 표시부(53)의 우측에는 실시간으로 용접이 되는 용접부재(W)의 정면과 측면을 나타낸 용접부재 표시부(54)가 마련된다.In addition, a welding member display unit 54 showing front and side surfaces of the welding member W to be welded in real time is provided on the right side of the welding bead shape display unit 53.
