본 고안은 완성된 음극선관을 검사용 편향요크등과 함께 정해진 위치에 적합하게 세트시켜 음극선관의 각종 전자기적 특성들을 정밀검사하는데에 사용되는 음극선관 검사대에 관한 것으로, 특히 검사시 음극선관에 걸리는 고압전류가 잔류하지 않도록 검사대 자체에서 완전방전토록하여 이러한 음극선관취급 및 검사상에 안전성을 높이고 또 잔류 고전압방전을 위한 별도의 방전작업을 생략할 수 있도록 안출한 것이다.The present invention relates to a cathode ray tube inspection table, which is used to precisely inspect various electromagnetic characteristics of the cathode ray tube by setting the completed cathode ray tube at a predetermined position together with an inspection deflection yoke, and the like. In order to ensure that the high voltage current is completely discharged from the inspection table itself, it is designed to increase safety in handling and inspecting such cathode ray tube and to omit a separate discharge operation for residual high voltage discharge.
이러한 종류의 음극선관 검사대는 전형적으로 하나의 음극선관을 높이조절이 자유롭게 지지하는 수단과 검사용 편향요크를 일정 높이상에서 전후 이동이 가능하게 지지하는 수단등을 기대에 설치구비하여 이들 수단을 통해 임의의 검사대상 음극선관을 검사의 목적에 맞게 적합히 세트시킨 다음 이 음극선관에 고전압을 걸어 모걱하는 바의 검사를 행할 수 있도록 되어 있는데, 검사후 상기 음극선관상에는 감전사고를 일으킬 수 있는 정도의 상당한 고전압이 잔류하게 된다.This type of cathode ray tube inspection table typically includes a means for supporting one cathode ray tube freely in height adjustment and a means for supporting an inspection deflection yoke to be moved back and forth on a certain height. The cathode ray tube to be inspected can be set appropriately for the purpose of the inspection, and then the high voltage is applied to the cathode ray tube to inspect the bar. After the inspection, a significant amount of electric shock may be caused on the cathode ray tube. High voltage will remain.
이와같이 음극선관에 잔류된 고전압은 이를 방전제거하지 않을 경우 추후의 취급과정이나 다른 검사과정에서의 불의의 감전사고를 불러 일으키거나 검사세트의 오동작 및 소손을 유발하는 큰 위험요인으로 작용하게 된다.As such, the high voltage remaining in the cathode ray tube causes a great risk factor that causes an accidental electric shock in a later handling process or other inspection process or causes malfunction and burnout of the test set.
종래의 음극선관 검사대는 검사의 목적에만 부합되도록 설계구성되어 검사된 음극선관상의 잔류고전압을 방전시켜줄 수 있는 수단을 구비하고 있지 않았기 때문에 이를 통해 검사를 마친 음극선관을 하나씩 일일히 별도의 방전수단을 통해 잔류 고전압의 방전처리를 해주어야 함으로써 그 과정에서 부주의로 인한 감전사고가 빈발했을 뿐만 아니라 방전처리를 위한 별도의 설비와 인력 및 시간이 소요되는 문제점이 있었다.The conventional cathode ray tube inspection table is designed and configured to meet the purpose of inspection only and does not include a means for discharging the residual high voltage on the inspected cathode ray tube. Through the discharge treatment of the residual high voltage through the process was not only frequent electric shock accidents due to carelessness, but also had a problem that requires a separate facility, manpower and time for the discharge treatment.
본 고안은 이러한 종래의 문제점을 효과있게 해소할 목적으로 안출된 새롭고 유용한 음극선관 검사장치인 것으로, 그 구체적인 구성내용과 작용효과를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is a new and useful cathode ray tube inspection device devised for the purpose of effectively solving such a conventional problem, the specific configuration and working effects will be described in detail based on the accompanying drawings.
첨부된 도면들에는 현재 음극선관의 전자기적 특성들을 검사하기 위해 사용되고 있는 한 전형적인 음극선관 검사대가 도시되어 있는데, 이 검사대는 도시된 바와 같이 기대(1)와, 이 기대상의 전방에 핸들(2)을 통해 승강조작될 수 있도록 설치된 리프트(3)와, 리프트(3) 상단에 결합설치된 음극선관받침대(4)와, 기대(1) 후방에 핸들(5)을 통해 전후이동조작될 수 있도록 설치된 가동틀체(6)와, 이 틀체(6)상에 검사용 편향요크(7)를 도시된 양태로 잡아 지지할 수 있도록 설치된 척장치(8)와, 척조정용 핸들(9)등의 요소들로 구성되어 있으며, 이는 받침대(4) 상애 검사대상 음극선관(10)을 올려놓고 핸들(2)로 리프트(3)를 상승조작하여 상기 음극선관을 소망되는 높이상에 위치시킨 다음 핸들(5)을 조작, 틀체(6)를 전진시켜 이 틀체(6)상에 척장치(8)를 통해 지지된 편향요크(7)를 제 2 도, 3 도와 같이 음극선관(10) 후부에 세트시킨 상태에서 목적하는 바의 검사를 행하도록 된 것이다.The accompanying drawings show one typical cathode ray tube inspection stand that is currently being used to inspect the electromagnetic properties of the cathode ray tube, which is the base 1 as shown and the handle 2 in front of the base. A lift (3) installed so as to be operated by lifting and lowering, a cathode ray tube support (4) coupled to the top of the lift (3), and a movable (5) installed at the rear of the base (1) so as to be moved back and forth through a handle (5) Consists of elements such as frame 6, chuck device 8 provided to hold and hold inspection deflection yoke 7 on the frame 6 in the illustrated embodiment, chuck adjustment handle 9 and the like. It puts the cathode ray tube 10 to be inspected on the pedestal 4 and lifts the lift 3 with the handle 2 to position the cathode ray tube at a desired height, and then operates the handle 5. , The frame body 6 is advanced to be supported by the chuck device 8 on the frame body 6. The incense yoke 7 2, is adapted to perform the inspection of the bar that purpose, while it is set to the rear cathode ray tube 10 as three help.
본 고안은 이러한 음극선관 검사대에 있어서, 상기 받침대(4)상에 예컨대 동판과 같은 전도성이 양호한 재질로 된 접지판(11)을 부착하되 이 접지판(11)상에 검사대상 음극선관(10)의 방폭밴드(10a)에 접지되는 받침돌부(11a)를 형성하고, 상기 받침돌부(11a) 일측에는 검사대상 음극선관(10)의 외장도전막(10b)에 접촉되는 접지코일(11b)을 부착설치하여서 된 것이다.According to the present invention, in the cathode ray tube inspection table, a ground plate 11 made of a good conductive material such as a copper plate is attached to the pedestal 4, and the cathode ray tube 10 to be inspected is placed on the ground plate 11. Forming a supporting protrusion 11a grounded at the explosion-proof band 10a, and attaching a grounding coil 11b to one side of the supporting protrusion 11a in contact with the exterior conductive film 10b of the cathode ray tube 10 to be inspected. It was installed.
이와같이 구성된 본 고안은 임의의 검사대상 음극선관(10)을 제 2 도, 3 도에 도시된 바와 같이 그 방폭랜드(10a)가 상기 받침돌부(11a)와 접촉되게 하는 동시에 외장도전막(10b)은 접지코일(11b)과 접촉되게 하여 검사대에 세트시켜 통상의 방법으로 검사를 행한 후 상기 음극선관(10)에 걸었던 전원을 해제하면 음극선관(10)에 잔류하는 고압전류가 상기와 같이 이의 방폭밴드(10a) 및 외장도전막(10b)에 접촉되어 있는 받침돌부(11a)와 접지코일(11b)을 통해 접지판(11)쪽으로 흘러 남김없이 자동방전되어지기 때문에 검사후 별도의 방전처리가 전혀 없고, 이에 따라 종래와 같이 검사가 행하여진 음극선관에 잔류하는 고전압으로 인한 감전사고의 위험성이 전혀 뒤따르지 않을 뿐만 아니라 방전처리를 위한 별도의 설비와 인력 및 시간을 절감할 수 있게 된 다대한 효과를 지닌 것이다.The present invention configured as described above allows any of the inspected cathode ray tubes 10 to be brought into contact with the supporting protrusions 11a at the same time as the explosion-proof land 10a as shown in FIGS. 2 and 3. Contact the ground coil 11b, set it on an inspection table, perform inspection in the usual manner, and then release the power applied to the cathode ray tube 10, so that the high voltage current remaining in the cathode ray tube 10 is Since the discharge is automatically discharged to the ground plate 11 through the support protrusion 11a and the ground coil 11b in contact with the explosion-proof band 10a and the outer conductive film 10b, a separate discharge treatment is performed after the inspection. There is no risk of electric shock due to the high voltage remaining in the cathode ray tube which has been inspected as in the prior art, and it is possible to save additional equipment, manpower and time for discharge treatment. Filial piety It is with.
