이러한, 용접 팁 드레싱 검사장치(100)는 몸체(110), 광전센서(120), 개폐부재(130)로 이루어진다.The welding tip dressing inspecting apparatus 100 includes a body 110, a photoelectric sensor 120, and an opening and closing member 130.

몸체(110)는 기본 골격이 되는 것으로서, 내부에는 광전센서(120)가 설치되는 공간부(미도시)가 형성되고, 외측면에는 용접 팁(12)이 안착되는 팁 안착부(112)가 공간부가 연통되게 형성된다.The body 110 has a basic skeleton and a space portion (not shown) in which the photoelectric sensor 120 is installed is formed therein. A tip seating portion 112, on which the welding tip 12 is seated, And is formed so as to communicate with each other.

또한, 몸체(110)의 측면에는 후술하는 커버(132)의 탄성 이동을 안내하는 가이드(114)가 설치된다. 이때, 가이드(114)에는 커버(132)의 측면이 끼워질 수 있는 안내홈(114a)이 형성된다. 이때, 커버(132)의 측면에는 안내돌기(132a)가 형성된다. 그러나, 이에 한정되지 않고 가이드(114)에 안내돌기를 형성하고, 커버(132)의 측면에 안내홈을 형성할 수 있다.A guide 114 for guiding the elastic movement of the cover 132, which will be described later, is provided on the side surface of the body 110. At this time, the guide 114 is formed with a guide groove 114a through which the side of the cover 132 can be fitted. At this time, a guide protrusion 132a is formed on the side surface of the cover 132. [ However, the present invention is not limited to this, and guide grooves may be formed on the side surfaces of the cover 132 by forming guide protrusions on the guide 114. [

그리고, 가이드(114)의 축선방향 소정 위치에는 리미트스위치(116)가 설치되는 것이 바람직하다. 즉, 리미트스위치(116)는 커버(132)에 의해 폐쇄되어 있던 팁 안착부(112)가 완전히 개방되는 시점을 제어부(미도시)에 알려줌으로써 용접 건(10)의 단부에 결합된 용접 팁(12)이 팁 안착부(112)에 정확하게 안착되게 한다.It is preferable that a limit switch 116 is provided at a predetermined position in the axial direction of the guide 114. That is, the limit switch 116 informs a control unit (not shown) when the tip seating unit 112, which was closed by the cover 132, is fully opened, 12 to be accurately seated in the tip seating portion 112.

아울러, 가이드(114)의 축선방향 소정 위치에는 팁 안착부(112)를 향해 에어를 분사할 수 있는 에어분사노즐(118)이 설치된다. 에어분사노즐(118)은 용접 팁(12)의 가압에 의해 커버(132)가 개방될 때 팁 안착부(112)에 에어를 분사하여 팁 안착부(112)에 존재하는 이물질이 제거되게 한다.In addition, an air injection nozzle 118 is provided at a predetermined position in the axial direction of the guide 114 so as to inject air toward the tip seating portion 112. The air injection nozzle 118 injects air into the tip seating portion 112 when the cover 132 is opened by pressing the welding tip 12 to remove foreign substances present in the tip seating portion 112.

광전센서(120)는 몸체(110)의 내부에 설치되어 팁 안착부(112)에 안착된 용접 팁(12)에 빛을 투광한 후 수광하여 용접 팁(12)의 드레싱 상태 및 오염물질의 부착유무를 검사한다. 광전센서(120)는 투광 및 수광을 할 수 있도록 두 개가 한 쌍으로 이루어지고, 각각은 단부에는 팁 안착부(112)와 마주보도록 센서홈(122)이 서로 반대방향으로 형성된다.The photoelectric sensor 120 is installed inside the body 110 to transmit light to the welding tip 12 mounted on the tip seating part 112 and receive the light so that the dressing state of the welding tip 12 and the attachment . The photoelectric sensor 120 is formed of two pairs so that light can be transmitted and received. Each end of the photoelectric sensor 120 is formed in a direction opposite to the sensor groove 122 so as to face the tip seating portion 112.

개폐부재(130)는 용접 팁(12)의 드레싱 상태 및 오염물질의 부착유무를 검사하지 않을 때 팁 안착부(112)를 폐쇄하여 팁 안착부(112) 및 팁 안착부(112)를 통해 광전센서(120)에 이물질이 유입되지 않게 하고, 용접 팁(12)의 드레싱 상태 및 오염물질의 부착유무를 검사하고자 할 때 팁 안착부(112)를 개방하여 광전센서(120)를 통해 용접 팁(12)의 드레싱 상태 및 오염물질의 부착유무를 검사할 수 있게 한다.The opening and closing member 130 closes the tip seating portion 112 when the dressing state of the welding tip 12 and the presence or absence of the contaminants are not inspected to allow the tip portion 112 and the tip seating portion 112, The tip seating part 112 is opened to inspect the dressing state of the welding tip 12 and the adhesion of the contaminants so that foreign matter does not flow into the sensor 120, 12) and the presence or absence of contaminants.

이러한, 개폐부재(130)는 몸체(110)의 측면에 팁 안착부(112)를 개폐하도록 설치된 커버(132)와, 커버(132)의 상부에 설치되고, 용접 팁(12)의 외주면 일부분이 안착되는 가압부(134)와, 커버(132)의 하부에 일단이 지지되고, 타단이 몸체(110)의 상면에 지지되는 탄성체(136)를 가진다.The opening and closing member 130 includes a cover 132 installed on the side surface of the body 110 to open and close the tip seating portion 112 and a cover 132 provided on the cover 132 and a portion of the outer circumferential surface of the welding tip 12 And a resilient body 136 whose one end is supported by the lower portion of the cover 132 and whose other end is supported by the upper surface of the body 110. [

여기서, 가압부(134)는 커버(132)의 상부에 설치된 지지대(134a)와, 지지대(134a)의 단부에 축회전 가능하게 결합되고, 외주면에는 용접 팁(12)의 외주면 일부분이 안착되는 안착홈(134c)이 형성된 가압롤러(134b)로 이루어진다. The pressing portion 134 is rotatably coupled to an end portion of the support base 134a and a support base 134a provided on the upper portion of the cover 132. On the outer circumferential surface of the support base 134a, And a pressure roller 134b having a groove 134c.

이와 같은 구성에 의해 용접 팁(12)이 지지대(134a)의 단부에 결합된 가압롤러(134b)의 안착홈(134c)에 안착된 상태로 커버(132)를 가압하면서 커버(132)가 개방되도록 수직 이동한 후 팁 안착부(112)를 향해 수평이동하면서 가압롤러(134b)를 축회전시키기 때문에 용접 팁(12)이 가압롤러(134b)에 회전에 의해 가이드 되면서 자연스럽게 팁 안착부(112)에 안착될 수 있고, 용접 팁(12)이 가압롤러(134b)로부터 이탈되어 검사장치 주변의 기타 기구부와 충돌하는 것을 방지할 수 있다.With this configuration, the cover 132 is opened while pressing the cover 132 while the welding tip 12 is seated in the seating groove 134c of the pressing roller 134b coupled to the end of the supporting table 134a The welding tip 12 is guided by the pressing roller 134b by rotation and naturally moves to the tip seating portion 112 as it moves horizontally toward the tip seating portion 112 after being vertically moved, And it is possible to prevent the welding tip 12 from separating from the pressure roller 134b and colliding with other mechanical parts around the inspection apparatus.

커버(132)는 가압부(134)에 안착되는 용접 팁(12)의 가압에 의해 탄성체(136)를 압축하면서 팁 안착부(112)를 개방하고, 용접 팁(12)에 의한 가압부(134)의 가압이 해제되었을 때 탄성체(136)의 탄성력에 의해 팁 안착부(112)를 폐쇄한다.The cover 132 opens the tip seating portion 112 while compressing the elastic body 136 by pressing the welding tip 12 seated on the pressing portion 134 and presses the pressing portion 134 by the welding tip 12 The tip seating portion 112 is closed by the elastic force of the elastic body 136. As a result,
