Description

정전기 제거용 통전 유닛{Electric current unit for removing static electricity}Electric current unit for removing static electricity

본 발명은 정전기 제거용 통전 유닛에 관한 것으로, 특히 PDP 패널 이송시스템에 적용되는 회전샤프트에 접속되어 정전기를 제거시킬 수 있도록 한 정전기 제거용 통전 유닛에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrostatic eliminating electrification unit, and more particularly, to an electrostatic eliminating electrification unit connected to a rotating shaft applied to a PDP panel transfer system to remove static electricity.

PDP(플라즈마 디스플레이 패널)는 기체의 방전에 의한 플라즈마를 이용해 영상을 발현시키는 장치이다. PDP는 제조시 상하판 내부에 RGB 형광체 및 ITO, MgO 등 박막을 형성·소성시키는 공정들과, 노광, 현상, 인쇄, 건조, 에칭 등의 공정들로 이루어진다.PDP (Plasma Display Panel) is an apparatus which expresses an image using plasma by gas discharge. PDP consists of processes for forming and firing thin films such as RGB phosphor, ITO, and MgO in the upper and lower plates during manufacturing, and processes such as exposure, development, printing, drying, and etching.

이러한 PDP 패널의 생산라인에서 PDP 패널의 물류 흐름을 위해 도 1과 같이 PDP 패널을 다수개의 롤러(2)로 지지하여 놓고, 롤러들을 회전샤프트(3)를 통해 회전 구동시키게 되어 있다.In the production line of the PDP panel, the PDP panel is supported by a plurality of rollers 2 as shown in FIG. 1 for the logistics flow of the PDP panel, and the rollers are driven to rotate through the rotary shaft 3.

따라서 회전샤프트(3)가 회전 구동되면 롤러(2)가 PDP 패널(1)을 일방향으로 이동 흘러가게 한다. 이때 발생된 정전기는 PDP 훼손과 불량을 야기한다.Therefore, when the rotary shaft 3 is driven to rotate, the roller 2 causes the PDP panel 1 to move in one direction. The static electricity generated at this time causes PDP damage and defects.

각 공정에서는 크린룸의 온, 습도 관리 및 이오나이저를 통하여 정전기 발생 을 억제하고 있으나 위와 같이 PDP 패널과 롤러와의 사이에서 발생되는 정전기를 제거시키기는 어려운 실정이다.In each process, static electricity is suppressed through temperature, humidity control and ionizer in the clean room, but it is difficult to remove static electricity generated between the PDP panel and the roller as described above.

따라서 본 발명은 상기와 같은 사정을 감안하여 창안된 것으로, PDP 패널 이송시스템의 롤러를 구동시키는 회전샤프트로부터 정전기를 즉시 접지로 흘려보내서 정전기를 제거하는 정전기 제거용 통전 유닛을 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, and an object thereof is to provide an electrostatic removal energization unit for removing static electricity by immediately flowing static electricity from the rotating shaft driving the roller of the PDP panel transfer system to ground. .

상기의 목적을 달성하기 위한 본 발명의 구체적인 수단은,Specific means of the present invention for achieving the above object,

PDP 패널을 이동시키는 구동롤러에 연결된 회전샤프트로부터 정전기를 제거하기 위한 정전기 제거용 통전 유닛에 있어서,In the electrostatic removal unit for removing static electricity from the rotating shaft connected to the drive roller for moving the PDP panel,

상기 회전샤프트와 결합되는 통전소켓과;An energizing socket coupled to the rotary shaft;

상기 통전소켓의 회전 중심선상에 위치하는 접지축과;A ground shaft positioned on a center line of rotation of the electricity supply socket;

상기 접지축과 통전소켓의 사이에 설치되어, 상기 접지축이 고정된 상태에서 상기 통전소켓의 회전이 자유롭도록 하는 베어링수단이 포함되어 구성된 것을 특징으로 한다.It is installed between the ground shaft and the power supply socket, characterized in that configured to include a bearing means for freely rotating the power supply socket in the state that the ground shaft is fixed.

또한 본 발명에 따르면,Also according to the invention,

상기 통전소켓의 내부에는 상기 접지축에 정전기를 전달하는 다수의 통전용 볼이 구비되어 있는 것을 특징으로 한다.The inside of the electricity supply socket is characterized in that a plurality of electricity supply balls for transmitting static electricity to the ground shaft is provided.

또한 본 발명에 따르면,Also according to the invention,

상기 회전샤프트는 상기 통전소켓에 하나 이상의 절개부를 갖는 삽입공에 삽입되고, The rotary shaft is inserted into the insertion hole having one or more incisions in the energized socket,

상기 통전소켓은 그의 외주면측 테이퍼부에 나사 체결된 너트에 의해 상기 회전샤프트에 고정 결합된 것을 특징으로 한다.The energizing socket is fixedly coupled to the rotary shaft by a nut screwed to its outer peripheral surface side tapered portion.

본 발명의 정전기 제거용 통전 유닛에 따르면, PDP 패널과 롤러와의 사이에서 발생된 정전기는 회전샤프트에 연결된 통전유닛을 통해 접지로 신속히 흐름된다. 따라서 정전기로 인한 PDP 패널의 훼손과 불량이 방지된다.According to the electrostatic eliminating electrification unit of the present invention, the static electricity generated between the PDP panel and the roller is quickly flowed to the ground through the energization unit connected to the rotary shaft. Therefore, damage and defects of the PDP panel due to static electricity are prevented.

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

도 1은 정전기가 발생되는 PDP 패널의 이동 시스템의 개념 및 본 발명의 통전유닛이 설치 상태를 나타내는 구성도이고, 도 2는 본 발명에 따른 정전기 제거용 통전 유닛의 구성도로서 조립단면도이고, 도 3은 본 발명에 따른 정전기 제거용 통전 유닛의 접지 사용상태도이고, 도 4는 도 3의 A-A선에서 본 단면도이다.1 is a block diagram showing the concept of the movement system of the PDP panel in which static electricity is generated and the installation state of the power supply unit of the present invention, Figure 2 is an assembly cross-sectional view as a block diagram of the power supply unit for removing static electricity according to the present invention, 3 is a ground use state diagram of the electrostatic unit for removing static electricity according to the present invention, Figure 4 is a cross-sectional view seen from the line AA of FIG.

도 1에서와 같이 PDP 패널(1)을 이동시키는 구동롤러(2)에 연결된 회전샤프트(3)로부터 정전기를 제거하기 위한 장치로서, 통전유닛(10)이 구비된다.As a device for removing static electricity from the rotary shaft 3 connected to the drive roller 2 for moving the PDP panel 1 as shown in FIG. 1, an electricity supply unit 10 is provided.

상기 통전유닛(10)은 도 1및 도 2에서와 같이 기본적으로 통전소켓(12), 접지축(14) 및 베어링(16)을 구성된다. 이때 이들 통전소켓(12), 접지축(14) 및 베어링(16)은 전도성 금속으로 제작된 것이다.As shown in FIGS. 1 and 2, the power supply unit 10 basically includes a power supply socket 12, a ground shaft 14, and a bearing 16. At this time, the energizing socket 12, the ground shaft 14 and the bearing 16 is made of a conductive metal.

상기 통전소켓(12)은 회전샤프트(3)와 연결되기 위해 일단에 1개 이상의 절개부(12b)를 갖는 삽입공(12a)이 형성되고, 상기 삽입공(12a)에 회전샤프트(3)가 끼워지게 되어 있다.The energizing socket 12 has an insertion hole 12a having one or more cutouts 12b at one end thereof so as to be connected to the rotary shaft 3, and the rotation shaft 3 is inserted into the insertion hole 12a. It is to be fitted.

또한 통전소켓(12)의 외주면에는 나사산(11)이 형성되어 있고, 나사산에는 상기 삽입공(12a)을 조임하기 위해 소정의 기울기(θ)(예로, 3도)를 갖는 테이퍼 구간이 존재한다. 따라서 나사산(11)에 나사 체결된 도 3 및 도 4의 너트(20)를 테이퍼 구간으로 이동시키면 삽입공(12a)의 내경이 수축하여 도 3과 같이 회전샤프트(3)에 확고히 고정 연결된다.In addition, a thread 11 is formed on the outer circumferential surface of the energizing socket 12, and a taper section having a predetermined inclination θ (for example, 3 degrees) exists in the thread to tighten the insertion hole 12a. Therefore, when the nut 20 of FIGS. 3 and 4 screwed to the thread 11 is moved to the tapered section, the inner diameter of the insertion hole 12a contracts and is firmly connected to the rotary shaft 3 as shown in FIG. 3.

상기 접지축(14)은 상기 통전소켓(12)의 회전 중심선상에 위치하여 베어링(16)을 매개로 통전소켓(12)에 연결되어 있다. 이때 상기 접지축(14)은 외주면에 수나사를 형성시켜 체결수단(너트)으로 접지선(100)을 고정시키도록 할 수 있다.The ground shaft 14 is located on the center line of rotation of the energizing socket 12 and is connected to the energizing socket 12 via a bearing 16. At this time, the ground shaft 14 may be a male screw on the outer circumferential surface to fix the ground wire 100 by a fastening means (nut).

본 실시예에서는 베어링(16)의 외륜에 통전소켓(12)이 끼움 결합되어 있고, 접지축(14)은 베어링(16)의 내륜에 끼움 결합되어 있다.In this embodiment, the energization socket 12 is fitted to the outer ring of the bearing 16, the ground shaft 14 is fitted to the inner ring of the bearing 16.

따라서 통전소켓(12)이 어느 방향으로 회전하여도 베어링(16)의 내륜과 결합된 접지축(14)은 회전하지 않는다.Therefore, even if the current supply socket 12 rotates in any direction, the ground shaft 14 coupled with the inner ring of the bearing 16 does not rotate.

한편, 바람직하게는 상기 통전소켓(12)의 내부에 상기 접지축(14)에 정전기를 전달하는 다수의 통전용 볼(18)이 구비된다.On the other hand, preferably, a plurality of balls for energizing 18 to transfer the static electricity to the ground shaft 14 is provided in the energizing socket 12.

이때 상기 통전용 볼(18)은 삽입공(12a)에 연통된 나사공(12c)을 통하여 조립되고, 이 나사공(12c)은 도시안된 플러그(plug) 의해 폐쇄된다.At this time, the electricity supply ball 18 is assembled through a screw hole 12c communicated with the insertion hole 12a, and the screw hole 12c is closed by a plug (not shown).

이와 같이 구성된 통전유닛(10)은 통전소켓(12)이 회전샤프트(3)와 일체로 회전하는 회전부가 되고, 접지축(14)이 고정단이 되고, 접지축(14)에 접지선(100)의 일단을 연결하고 접지선(100)의 타단을 대지에 연결시킴으로서 정전기를 제거하기 위한 접지 회로가 이루어진다.The power supply unit 10 configured as described above is a rotary part in which the power supply socket 12 rotates integrally with the rotary shaft 3, the ground shaft 14 becomes a fixed end, and the ground wire 100 on the ground shaft 14. The ground circuit for removing static electricity is made by connecting one end of the wire and connecting the other end of the ground wire 100 to the earth.

이를 위해 통전유닛(10)은 회전샤프트(3)에 결합시킨다.To this end, the energizing unit 10 is coupled to the rotary shaft (3).

먼저, 통전소켓(12)의 삽입공(12a)을 회전샤프트(3)의 말단부에 끼워넣은 후 너트(20)를 체결한다.First, the insertion hole 12a of the energization socket 12 is inserted into the distal end of the rotary shaft 3, and then the nut 20 is fastened.

이렇게 되면 삽입공(12a)이 회전샤프트(3)를 조임하여 통전소켓(12)과 회전샤프트(3)의 결합이 완료된다.In this case, the insertion hole 12a tightens the rotation shaft 3 to complete the coupling of the energization socket 12 and the rotation shaft 3.

다음, 접지축(14)에 접지선(100)의 일단을 연결하고, 이 접지선(100)의 타단을 대지에 연결시켜 놓음으로써 정전기 처리 회로가 이루어진다.Next, one end of the ground wire 100 is connected to the ground shaft 14, and the other end of the ground wire 100 is connected to the ground to form an electrostatic treatment circuit.

따라서 도 1에서와 같이 PDP 패널(1)의 이동중에 PDP 패널(1)과 롤러(2)와의 사이에서 발생된 정전기는 도 3과 같이 회전샤프트(3), 통전유닛(10)을 순차적으로 거친 후 접지로 흐름된다.Therefore, as shown in FIG. 1, the static electricity generated between the PDP panel 1 and the roller 2 during the movement of the PDP panel 1 passes through the rotary shaft 3 and the energizing unit 10 sequentially as shown in FIG. 3. Then flows to ground.

이때 통전유닛(10)에서는 통전소켓(12), 통전볼(18), 접지축(14)의 순으로 정전기가 신속히 흐르게 된다. 또한 접지선(100)은 접지축(14)에 연결되고, 접지축(14)은 통전소켓(12)의 회전으로부터 자유롭게 고정되어 있으므로 꼬임되는 현상을 발생되지 않는다.At this time, in the energization unit 10, the static electricity flows quickly in the order of the energization socket 12, the energization ball 18, the ground shaft (14). In addition, the ground wire 100 is connected to the ground shaft 14, the ground shaft 14 is free from the rotation of the power supply socket 12, so there is no twisting phenomenon occurs.

따라서 도 1과 같이 PDP 패널(1)을 롤러(2)로 지지하여 놓고, 회전 샤프트(3)를 회전 구동시겨 PDP 패널(1)을 이동시킬 경우 롤러(2)와 PDP 패널(1)의 사이에서 발생되는 정전기가 통전유닛(10)을 통해 즉시 접지되어 흐름으로써 정전기로 인한 PDP 패널의 훼손과 불량은 발생되지 않는다.Therefore, the PDP panel 1 is supported by the roller 2 as shown in FIG. 1, and the roller 2 and the PDP panel 1 are moved when the rotation shaft 3 is driven to move the PDP panel 1. Since the static electricity generated between the ground immediately flows through the conduction unit 10, the damage and defect of the PDP panel due to the static electricity does not occur.

본 실시예에서 베어링(16)은 볼 베어링으로 구성하였으나 본 발명은 이에 한정되는 것은 아니며 롤러 베어링 등으로 선택될 수 있음은 물론이다.In the present embodiment, the bearing 16 is configured as a ball bearing, but the present invention is not limited thereto and may be selected as a roller bearing.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto, and the technical idea of the present invention and the following by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
