Description
본 발명은, 패널연마용 툴에 관한 것으로서, 보다 상세하게는, 음극선관용 패널의 표시면을 연마하는 패널연마용 툴에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool for panel polishing, and more particularly, to a panel polishing tool for polishing a display surface of a cathode ray tube panel.
일반적으로 음극선관은 화상이 투사되는 패널과, 패널의 배후에 결합되는 깔때기 형상의 펀넬과, 전자총을 구비하여 펀넬에 결합되는 넥크를 가진다. 패널은 화상이 투사되는 표시면과, 표시면의 연부로부터 둘레 방향을 따라 절곡형성된 스커트부를 가진다.Generally, a cathode ray tube has a panel on which an image is projected, a funnel-shaped funnel coupled to the rear of the panel, and a neck coupled to the funnel with an electron gun. The panel has a display surface on which an image is projected and a skirt portion bent along the circumferential direction from the edge of the display surface.
패널은 압축성형장치에 의해 성형된 후, 표시부 및 접합단면부의 연마과정을 거쳐 펀넬과 플리트실링에 의해 접합된다.The panel is molded by a compression molding apparatus, and then bonded by a funnel and pleat sealing through a polishing process of the display portion and the bonded end portion.
도 3은 종래의 패널연마용 툴이 장착된 연마장치의 부분단면도이고, 도 4는 도 3의 패널연마용 툴의 저면도이다. 이들 도면에 도시된 바와 같이, 축심을 따라 연마재공급로(102)가 형성된 연마장치의 회전스핀들(101)의 하단에는 반경방향을 따라 연장된 툴장착부(105)가 형성되어 있으며, 툴장착부(105)에는 패널연마용 툴(107)이 일체로 회전가능하도록 결합되어 있다.3 is a partial cross-sectional view of a polishing apparatus equipped with a conventional panel polishing tool, and FIG. 4 is a bottom view of the panel polishing tool of FIG. As shown in these figures, a tool mounting portion 105 extending along the radial direction is formed at the lower end of the rotary spindle 101 of the polishing apparatus in which the abrasive supply path 102 is formed along the axis, and the tool mounting portion 105 ) Is coupled to the panel polishing tool 107 to be integrally rotatable.
회전스핀들(107)의 하측에는 연마될 패널(109)이 적치될 수 있도록 웨어테이블(111)이 배치되어 있으며, 웨어테이블(111)에는 원형고리상의 지지부재(113)가 고정되어 패널(109)을 수용지지하고 있다.A wear table 111 is disposed at the lower side of the rotary spindle 107 so that the panel 109 to be polished can be loaded. Is supported.
한편, 패널연마용 툴(107)은 회전스핀들(101)의 툴장착부(105)에 결합되는 고정부(121)와, 고정부(121)의 일측 판면으로부터 돌출형성되어 패널(109)의 표면을 접촉연마하는 복수의 연마부(131)를 가진다. 고정부(121)의 중앙영역에는 회전스핀들(101)의 축심을 따라 형성된 연마재공급로(102)와 연통되도록 관통공(123)이 형성되어 있으며, 고정부(121)의 연부에는 툴장착부(105)에 형성된 볼트공과 상호 연통되도록 복수의 볼트통과공(125)이 둘레방향을 따라 형성되어 있다.Meanwhile, the panel polishing tool 107 is formed to be fixed to the fixing part 121 coupled to the tool mounting part 105 of the rotary spindle 101 and protrudes from one side surface of the fixing part 121 to form the surface of the panel 109. It has a some grinding | polishing part 131 contact-polishing. A through hole 123 is formed in the central area of the fixing part 121 so as to communicate with the abrasive supply path 102 formed along the axis of the rotary spindle 101, and the tool mounting part 105 is formed at the edge of the fixing part 121. A plurality of bolt through holes 125 are formed along the circumferential direction so as to be in communication with the bolt holes formed in the).
각 연마부(131)는 고정부(121)의 판면으로부터 부채꼴형상을 가지도록 소정 돌출되어 방사상을 따라 배치되며, 각 연마부(131)의 사이영역에는 슬러리상의 연마재가 배출될 수 있도록 연마재배출로(127)가 방사상을 따라 형성되어 있다. 그리고, 각 연마부(131)에는 말단영역으로부터 방사상을 따라 소정 절취된 연마재배출로(129)가 형성되어 있다.Each abrasive part 131 is disposed along the radial direction by a predetermined protrusion so as to have a fan shape from the plate surface of the fixing part 121, and the abrasive discharge path to discharge the slurry-like abrasive material in the area between each abrasive part 131. 127 is formed along the radial line. Each abrasive portion 131 is provided with an abrasive discharge path 129 cut along a radial direction from the distal region.
그런데, 이러한 종래의 패널연마용 툴에 있어서는, 연마재배출로가 방사상으로 형성되어 있어 연마재의 체류시간이 충분히 확보되지 못하게 되어 연마력이 떨어지게 될 뿐만 아니라, 연마력향상을 위해 큰 가압력을 가지고 패널과 연마툴이 접촉됨으로 연마부의 열화가 비교적 쉽게 발생되는 문제점이 있다. 또한, 연마부가 부채꼴형상을 가지도록 형성되어 있어 표시면이 복합곡률로 형성되는 비구면패널의 경우 균일한 연마면을 얻기가 어렵다는 문제점이 있다.By the way, in such a conventional panel polishing tool, the abrasive discharge path is radially formed so that the residence time of the abrasive is not sufficiently secured so that the polishing force is lowered, and the panel and the polishing tool have a large pressing force to improve the polishing force. There is a problem that deterioration of the polishing portion occurs relatively easily due to this contact. In addition, in the case of the aspherical panel having the polishing portion having a fan shape, the display surface is formed with a compound curvature, there is a problem that it is difficult to obtain a uniform polishing surface.
따라서, 본 발명의 목적은, 연마재의 체류시간을 연장시켜 연마력을 향상시킬 수 있으며 연마부의 열화를 억제시킬 수 있는 패널연마용 툴을 제공하는 것이다. 본 발명의 다른 목적은, 균일한 연마면을 얻을 수 있는 패널연마용 툴을 제공하는 것이다.Accordingly, an object of the present invention is to provide a tool for panel polishing, which can improve the polishing force by extending the residence time of the abrasive and suppress the deterioration of the polishing portion. Another object of the present invention is to provide a tool for panel polishing which can obtain a uniform polishing surface.

도 1은 본 발명에 따른 패널연마용 툴이 장착된 상태를 도시한 패널연마장치의 부분단면도이다. 도시된 바와 같이, 패널연마장치의 회전스핀들(1)의 하단에는 반경방향을 따라 연장된 툴장착부(5)가 형성되어 있으며, 툴장착부(5)에는 패널연마용 툴(7)이 일체로 회전가능하도록 결합되어 있다. 회전스핀들(1)의 하측에는 웨어테이블(11)상에 고정된 지지부재(13)내에 연마될 패널(9)이 회전가능하도록 지지되어 있다.1 is a partial cross-sectional view of a panel polishing apparatus showing a state in which a panel polishing tool according to the present invention is mounted. As shown, a tool mounting portion 5 extending along the radial direction is formed at the lower end of the rotary spindle 1 of the panel polishing apparatus, and the tool polishing portion 7 rotates integrally on the tool mounting portion 5. Are combined as possible. On the lower side of the rotary spindle 1, the panel 9 to be polished in the support member 13 fixed on the wear table 11 is rotatably supported.
한편, 본 발명에 따른 패널연마용 툴(7)은 회전스핀들(1)의 툴장착부(5)에 결합되는 고정부재(21)와, 패널(9)의 표면을 접촉연마하는 복수의 연마돌기(33)를 가지고 고정부재(21)의 일표면에 접촉결합되는 연마부재(31)를 가진다.Meanwhile, the panel polishing tool 7 according to the present invention includes a fixing member 21 coupled to the tool mounting part 5 of the rotary spindle 1 and a plurality of polishing protrusions contacting and polishing the surface of the panel 9. 33) and a polishing member 31 in contact with one surface of the fixing member 21.
도 2는 도 1의 패널연마용 툴의 확대저면도이다. 도시된 바와 같이, 고정부재(21)는 원형의 판상부재로 형성되며, 고정부재(21)의 연부에는 회전스핀들(1)의 툴장착부(5)에 형성된 결합공과 상호 연통되도록 복수의 볼트통과공(25)이 둘레방향을 따라 형성되어 있다. 고정부재(21)의 중앙영역에는 회전스핀들(1)의 축심을 따라 형성된 연마재공급로(2)와 상호 연통되도록 관통공(23)이 형성되어 있다.FIG. 2 is an enlarged bottom view of the panel polishing tool of FIG. 1. As shown, the fixing member 21 is formed of a circular plate-like member, the plurality of bolt through holes to be in communication with the coupling hole formed in the tool mounting portion 5 of the rotary spindle 1 at the edge of the fixing member 21 25 is formed along the circumferential direction. The through hole 23 is formed in the central region of the fixing member 21 so as to communicate with the abrasive feed path 2 formed along the axis of the rotary spindle 1.
연마부재(31)는 고정부재(21)에 비해 축소된 반경을 가지며 판면에는 육각단면형상을 가지는 복수의 연마돌기(33)가 형성되어 있으며, 연마돌기(33)의 사이영역에는 파형상의 연마재배출로(35)가 형성되어 있어 평면투영시 전체적인 모습은 허니콤(Honey Comb)형상을 가지게 된다.The polishing member 31 has a radius smaller than that of the fixing member 21, and a plurality of polishing protrusions 33 having a hexagonal cross-sectional shape are formed on the plate surface, and a wavy abrasive discharge is formed in the region between the polishing protrusions 33. The furnace 35 is formed so that the overall appearance has a honeycomb (Honey Comb) shape when projecting.
여기서, 고정부재(21)와 연마부재(31)는 상호 다른 재질의 고무부재로 형성되며 연마부재(31)에 비해 고정부재(21)를 연질의 고무부재로 하는 것이 바람직하다. 예를 들면, 고정부재(21)는 신축성이 우수한 천연고무부재로 형성하고, 연마부재(31)는 내마모특성이 우수한 클로르프랜고무부재와 같은 합성고무부재로 형성하는 것이 효과적이다. 상호 다른 재질의 고무부재로 각각 형성된 연마부재(31)와 고정부재(21)는 접착제 등에 의해 상호 결합된다.Here, the fixing member 21 and the polishing member 31 is formed of a rubber member of a different material, it is preferable to use the fixing member 21 as a soft rubber member compared to the polishing member 31. For example, it is effective that the fixing member 21 is formed of a natural rubber member having excellent elasticity, and the polishing member 31 is formed of a synthetic rubber member such as chloroprene rubber member having excellent wear resistance. The polishing members 31 and the fixing members 21 formed of rubber members of different materials are joined to each other by an adhesive or the like.
이러한 구성에 의하여, 회전스핀들(1)의 하단에 형성된 툴장착부(5)에 형성된 결합공과 고정부재(21)의 둘레연부에 형성된 볼트통과공(25)이 상호 연통되도록 하고, 고정부재(21)와 툴장착부(5)를 체결용 볼트(37) 및 너트(39)로 체결고정되도록 한다.By this configuration, the coupling hole formed in the tool mounting portion 5 formed at the lower end of the rotary spindle 1 and the bolt passing hole 25 formed at the circumferential edge of the fixing member 21 to communicate with each other, the fixing member 21 And the tool mounting portion 5 to be fastened and fastened with a fastening bolt 37 and a nut 39.
웨어테이블상(11)에 연마될 패널(9)이 적치되면 회전스핀들(1)이 하강을 개시하게 되며, 회전스핀들(1)이 회전을 개시하게 되면 웨어테이블(11)상에 적치된패널(9)은 웨어테이블(11)과 함께 회전스핀들(1)과 반대방향으로 회전하게 된다. 이 때, 패널(9)의 표시면에는 회전스핀들(1)의 축심을 따라 형성된 연마재공급로(2)를 통하여 슬러리상의 연마재가 공급되며 연마돌기(33)는 패널(9)의 표시면에 가압접촉된다.When the panel 9 to be polished on the wear table 11 is loaded, the rotating spindles 1 start to descend, and when the rotating spindle 1 starts to rotate, the panel deposited on the wear table 11 ( 9) rotates in a direction opposite to the rotating spindle 1 with the wear table (11). At this time, a slurry-like abrasive is supplied to the display surface of the panel 9 through the abrasive supply path 2 formed along the axis of the rotary spindle 1 and the polishing protrusion 33 is pressed against the display surface of the panel 9. Contact.
그러면, 연마재는 연마돌기(33)와 패널(9)의 표시면사이에 개재되어 연마작용을 수행하게 되며, 이 때, 연마돌기사이영역에 파형상을 가지도록 형성된 연마재 배출로(35)에 의해 연마재의 배출시간이 지연됨으로써 연마력이 향상되게 된다.Then, the abrasive is interposed between the abrasive projection 33 and the display surface of the panel 9 to perform the polishing action, at this time, by the abrasive discharge path 35 formed to have a wavy shape in the region between the abrasive projections As the discharge time of the abrasive is delayed, the polishing force is improved.
또한, 패널(9)의 표시면을 따라 접촉선회하는 연마돌기(33)는 내마모성이 우수한 클로르프랜고무부재와 같은 합성고무부재로 형성되므로 교체주기를 연장시키게 되며, 비교적 연질의 천연고무부재로 형성된 고정부재(21)에 의해 탄성지지됨으로써 복합곡률로 형성된 비구면 표시면을 효과적으로 연마하게 된다.In addition, the abrasive projections 33 contacting along the display surface of the panel 9 are formed of a synthetic rubber member such as chloroprene rubber member having excellent abrasion resistance, thereby extending the replacement period, and being formed of a relatively soft natural rubber member. By being elastically supported by the fixing member 21, the aspherical display surface formed by the compound curvature is effectively polished.
이상 설명한 바와 같이, 본 발명에 따르면, 연마재의 체류시간을 연장시켜 연마력을 향상시킬 수 있으며 연마부의 열화를 억제시킬 수 있는 패널연마용 툴이 제공된다. 그리고, 연마돌기가 연질의 고정부재에 의해 탄성지지됨으로써 비교적 균일한 연마면을 얻을 수 있다.As described above, according to the present invention, there is provided a tool for panel polishing, which can improve the polishing force by extending the residence time of the abrasive and suppress the deterioration of the polishing portion. Then, the polishing protrusion is elastically supported by the soft fixing member to obtain a relatively uniform polishing surface.
