이하, 본 발명의 동작과정에 대하여 설명하면 다음과 같다.Hereinafter, the operation of the present invention will be described.

상기한 바와 같이 용접 마스크에 있어서, 용접 마스크부(220)의 전면에 구비한 카메라(110)와, 초기 용접작업전 작업자가 용접 마스크를 착용한 상태에서 용접부위를 확인할 수 있도록 상기 카메라(110)로부터 전송된 영상을 용접투시창(230) 측 내면에 구비한 LCD디스플레이부(120)와, 용접 마스크부(220)의 전면에 초기 용접작업시 발생하는 용접불꽃을 감지하여 LCD디스플레이부(120) 에서의 용접 영상 디스플레이 동작이 차단되게 함과 더불어 투광동작시켜 용접투시창(230)을 통하여 투과된 용접작업불꽃을 작업자가 볼 수 있게 용접 마스크부(220)의 전면에 구비한 용접불꽃센서(130) 및 LCD디스플레이부(120)의 동작을 위한 전원을 공급하는 전원부(140)로 구성한 것이다.

여기서, 상기 LCD디스플레이부(120)는 용접투시창(230) 측에 구비되어 외부로부터의 빛이 내부로만 투과되게 구성된 디스플레이반밀러(121)와, 상기 디스플레이반밀러(121)의 전면에 구비되어 빛의 투과를 제어하는 액정부(122)와, 상기 디스플레이반밀러(121)와 액정부(122) 사이의 측면에 구비되어 액정부(122)의 디스플레이를 위한 빛을 조사하는 디스플레이조광부(123) 및 상기 디스플레이조광부(123) 및 액정부(122)의 동작을 제어하는 디스플레이제어부(124)로 구성한 본 발명이 적용된 용접 마스크를 착용하게 되면, 착용부(210)에 구비된 착용감압센서(161)가 디스플레이제어부(124)에 착용신호를 전송한다.As described above, in the welding mask, the camera 110 provided on the front surface of the welding mask part 220 and the camera 110 so that the operator can check the welding part in a state in which the operator wears the welding mask before the initial welding operation. LCD display unit 120 provided on the inner surface of the welding viewing window 230 and the welding flame generated during the initial welding operation on the front surface of the welding mask unit 220 is detected by the LCD display unit 120. And a welding flame sensor 130 provided on the front side of the welding mask unit 220 to allow a worker to see the welding work flame transmitted through the welding see-through window 230 by the light emission operation. It is composed of a power supply unit 140 for supplying power for the operation of the LCD display unit 120.

Here, the LCD display unit 120 is provided on the welding see-through window 230 side, the display vane mirror 121 is configured to transmit the light from the outside only to the inside, and is provided on the front of the display vane mirror 121 light A liquid crystal part 122 for controlling the transmission of light and a display illuminating part 123 provided at a side surface between the display vane mirror 121 and the liquid crystal part 122 to irradiate light for display of the liquid crystal part 122. And a wearing pressure sensor 161 provided in the wearing unit 210 when the welding mask to which the present invention is configured includes the display lighting unit 123 and the display control unit 124 controlling the operation of the liquid crystal unit 122. ) Transmits a wearing signal to the display control unit 124.

그리고, 작업자가 용접 마스크부(220)를 닫게 되면 힌지부(211)에 구비된 닫힘감지센서(162)가 이를 감지하여 디스플레이제어부(124)에 닫힘 신호를 전송한다.Then, when the worker closes the welding mask 220, the closing sensor 162 provided in the hinge portion 211 detects this and transmits a closing signal to the display control unit 124.

이상과 같이 착용감압센서(161)와 닫힘감지센서(162) 모두에서 신호가 입력되면 디스플레이제어부(124)가 디스플레이조광부(123)와 액정부(122)를 제어하여 용접 마스크부(220)의 전면에 구비된 카메라(110)에서 촬영된 영상이 LCD디스플레이부(120)에 디스플레이되게 하여 작업자가 용접 마스크부(220)를 닫은 상태에서도 용접부를 확인할 수 있게 되는 것이다.As described above, when a signal is input from both the wearing pressure reducing sensor 161 and the closing detecting sensor 162, the display control unit 124 controls the display dimming unit 123 and the liquid crystal unit 122 to control the welding mask unit 220. The image captured by the camera 110 provided on the front side is displayed on the LCD display unit 120 so that the operator can check the weld even when the welding mask unit 220 is closed.

상기한 바와 같이 용접 마스크부(220)를 닫은 상태에서 용접부를 터치하여 용접을 실시하게 되면, 용접불꽃센서(130)가 이를 감지하여 디스플레이제어부(124)로 용접불꽃감지신호를 전송함으로써 LCD디스플레이부(120)의 동작이 정지되고 용접투시창(230)을 통하여 감광 투시되는 용접불꽃을 확인하며 용접작업을 실시할 수 있게 되는 것이다.As described above, when the welding is performed by touching the welding unit while the welding mask unit 220 is closed, the welding flame sensor 130 detects this and transmits the welding flame detection signal to the display control unit 124. The operation of the 120 is stopped and the welding flame which is photosensitive through the welding see-through window 230 is to be able to perform the welding operation.

한편, 상기 용접불꽃센서(130)에 의한 용접불꽃감지가 이루어지면 상기 용접불꽃센서(130)에서 감지된 불꽃 감지신호가 용접불꽃차단셔터(111)로 전송되어 상기 용접불꽃차단셔터(111)가 닫힘 동작 됨으로써 용접불꽃에 의한 카메라(110)의 촬상소자 손상이 방지되는 것이다.On the other hand, when the welding flame detection by the welding flame sensor 130 is made, the flame detection signal detected by the welding flame sensor 130 is transmitted to the welding flame blocking shutter 111 to the welding flame blocking shutter 111 The closing operation is to prevent damage to the image pickup device of the camera 110 by the welding spark.

또한, 상기 카메라(110)를 통하여 용접과정의 과도한 조도의 용접불꽃 영상이 촬영되어 전송되게 되면, 영상조도조정부(150)가 이를 감지하여 전송되는 영상의 조도를 조절하여 전송되게 하여 과도한 조도의 영상신호가 전송되어 LCD디스플레이부(120)에서 디스플레이되는 것을 차단되게 하여 작업자를 보호할 수 있게 하는 것이다.
In addition, when the welding flame image of the excessive illumination of the welding process is photographed and transmitted through the camera 110, the image illumination adjustment unit 150 detects it and adjusts the illumination of the transmitted image to transmit the image of the excessive illumination The signal is transmitted to block the display on the LCD display unit 120 to protect the operator.
