Description
본 고안은 LCD(Liquid Crystal Dispaly)용 더미 실(Dummy Seal)에 관한 것으로, 특히 원판상에 LCD용 셀을 놓고 두장의 원판을 겹쳐서 진공하여 실링함에 있어서 두장의 원판이 실링(Sealing)시에 미끄러짐이나 비틀림을 방지할 뿐만 아리나 셀(Cell)의 분리시에 깨짐을 방지하기 위한 깨짐방지용 더미 실 구조체에 관한 것이다.The present invention relates to a dummy seal for liquid crystal dispersion (LCD), and in particular, two discs slide during sealing when a cell for LCD is placed on a disc and two discs are overlapped and vacuum-sealed. The present invention relates to a crack preventing dummy seal structure for preventing breakage during separation of the cell or the cell.
종래에는 LCD용 사용되는 더미 실(Dummy Seal)의 구조형태는 원판의 글래스(2)상에 LDC용 셀(8)을 보통 두장을 얻어 놓고 진공하면서 실링(Sealing) 작업을 하였다.Conventionally, in the form of a dummy seal used for an LCD, two sheets of the LDC cell 8 are usually obtained on a glass 2 of a disc, and sealing is performed while vacuuming.
상기 원판의 글래스(2)상에 두장의 셀(8)을 올려 놓은 후 상부측에 글래스(2)를 겹쳐서 실링함에 있어서 상기 두장의 글래스(2)를 겹쳐서 실링하게 되면 글래스의 표면이 미끄럽기 때문에 두장을 겹쳐서 가압하여 실링시에 미끄러지거나 비틀림 등이 나타나는 문제점으로 인하여 상기 원판의 글래스(2)에 셀(8)이 놓여진 부분의 외부측상에 길게 더미 실(6a,6b)을 형성하고 있다.When the two sheets of glass 8 are placed on the glass 2 of the disc, and the two glasses 2 are overlapped to seal the glass 2 on the upper side, the surface of the glass is slippery. Due to the problem of slipping and twisting at the time of sealing by overlapping the two sheets, dummy seals 6a and 6b are formed long on the outer side of the portion where the cell 8 is placed on the glass 2 of the disc.
상기 종래의 사용되어 오고 있는 더미 실(6a,6b)은 길게 형성되어 더미 실(6)의 끝부분이 더미 실(6a)과 더미 실(6b)의 끝부분 즉 원판 글래스(2)의 모서리 부분의 측이 연결이 되지 않은 것으로 진공하면서 셀(8)을 실링할 때 내부의 공기를 밖으로 내보내주는 통로 역할을 해주도록 되어 있다.The conventionally used dummy seals 6a and 6b are formed long so that the end of the dummy seal 6 is the end of the dummy seal 6a and the dummy seal 6b, that is, the corner portion of the disc glass 2. The side of is not connected to serve as a passage to discharge the air inside when sealing the cell 8 while vacuuming.
그러나 상기와 같은 종래의 원판 글래스(2)상에 형성된 미끄럼 방지용 더미 실(6a,6b)과 같은 구조는 셀(8)의 실링작업이 끝난후에 원하는 크기의 셀을 떼어내기 위한 스크라이브 작업시 더미 실(6a,6b)의 구조에 의해 힘을 받는 부분이 일정하지 않아 이탈된 셀(8)의 한쪽면이 거칠어져 불량품이 많이 발생되거나 더미 실(6a,6b)의 끝부분이 구조상 연결되어 있지않은 것으로 이와 같은 문제점이 발생되었고, 상기 셀의 크기가 대형으로 되어짐에 의해 원판 글래스(2)의 크기가 커지기 때문에 이동시 더미 실(6a,6b)이 형성되어 있지 않은 부분으로 인한 서로 힘에 대한 응력의 차이가 생겨 셀이 깨지는 문제점이 발생되었다.However, such a structure as the non-slip dummy seals 6a and 6b formed on the conventional disc glass 2 as described above is a dummy seal during scribing to detach a cell of a desired size after the sealing operation of the cell 8 is finished. Due to the structure of (6a, 6b), the part subjected to the force is not constant, so that one side of the detached cell 8 is roughened, causing a lot of defective products, or the ends of the dummy seals 6a, 6b are not structurally connected. This problem has occurred, and since the size of the cell increases, the size of the disc glass 2 increases, so that the stress on the force of each other due to the portion where the dummy seals 6a and 6b are not formed during the movement. The difference caused the cell breakage.
상술한 종래의 문제점을 감안하여 창안된 것으로, 본 고안의 목적은 작업자가 원하는 크기의 셀을 떼어내는 작업인 스크라이브 작업시 셀이 깨지는 것을 방지할 수 있는 깨짐방지용 더미 실 구조체를 제공함에 있다.The present invention was devised in view of the above-described problems, and an object of the present invention is to provide a dummy seal structure for preventing breakage of a cell during a scribing operation in which a worker detaches a cell of a desired size.

본 고안은 상기와 같은 목적을 달성하기 위하여, 깨짐방지용 더미 실 구조체를 LCD용 셀의 실링작업시 미끄럼방지와 비틀림 방지를 위한 더미 실에 있어서, 원판 글래스강의 셀이 놓여져 있는 셀의 모서리부분을 감싸도록자형 더미 실과 대향되는자형 더미 실(20b)를 형성하고, 셀(26)의 면부분측에는 공기통로(28)가 형성되도록 일자형 더미 실(21)이 형성되어 있는 것이 특징이다.The present invention, in order to achieve the above object, in the dummy seal for preventing slipping and torsion during the sealing operation of the LCD cell to prevent the breakage of the dummy seal structure, wrap the edge of the cell where the cell of the disc glass steel is placed so that As opposed to the dummy pile thread The dummy dummy chamber 20b is formed, and the straight dummy chamber 21 is formed on the surface portion side of the cell 26 so that the air passage 28 is formed.
상기와 같이 구성된 본 고안의 깨짐방지용 더미 실 구체를 첨부된 도면을 참조하여 상세하게 설명한다.With reference to the accompanying drawings will be described in detail with reference to the accompanying drawings, the dummy seal sphere of the present invention configured as described above.
도 2는 본 고안의 더 실 구조체를 나타내는 도면이다.2 is a view showing a more seal structure of the present invention.
LCD용 셀의 실링작업시 미끄럼방지와 비틀림 방지를 위하여 더미 실을 원판의 글래스상에 형성하는 것으로 상기 두장의 셀(26)을 보통 아래위로 놓고 실링 작업을 하도록 되어 있다.In order to prevent slipping and torsion during sealing of LCD cells, dummy seals are formed on the glass of the original plate to seal the two sheets of cells 26 up and down.
원판 글래스(24)상에 보통 두장의 셀(26)이 놓여지게 되면 두장의 셀(26)이 놓여진 부분의 상부측 모서리부분과 하부측 모서리부분에 실링작업시 또는 스크라이브 작업시 받는 힘의 응력을 균일하게 셀(26)의 모서리부분을 감쌓도록자형 더미 실(20a)과 마주보도록자형 더미 실(20b)를 형성한다.When two cells 26 are normally placed on the disc glass 24, the stress of the force applied during sealing or scribing is applied to the upper and lower corners of the portion where the two cells 26 are placed. To evenly wrap the edges of the cell 26 To face the female dummy seal 20a The male dummy chamber 20b is formed.
상기와 같이자형 더미 실(20a,20b)을 셀(26)의 모서리부에 형성하고, 더미 실이 형성되지 않은 부분인 셀(26)의 면부분측에는 공기통로(28)가 형성되도록 일자형 더미 실(21)을 겹치게 형성한다.As above The linear dummy chambers 21 are formed so that the female dummy chambers 20a and 20b are formed at the corners of the cell 26 and the air passage 28 is formed at the side of the surface portion of the cell 26 which is a portion where the dummy chambers are not formed. Form overlap.
상기자형 더미 실(20a,20b)과 일자형 더미 실(21)을 겹치게 형성하므로 두자의 글래스에서 발생되는 내부공기는 공기통로(28)를 통하여 쉽게 배출된다.remind Since the dummy dummy seals 20a and 20b and the straight dummy seal 21 overlap each other, internal air generated from the glass of the two characters is easily discharged through the air passage 28.
따라서, 본 고안의 더미 실 구조체는 상기 원판 글래스(24)상에서 실링된 셀(26)을 원하는 크기로 떼어내는 스크레이브 작업시 원판의 글래스를 들어서 작업을 할 경우에 종래에는 더미 실이 있는 부분과 없는 부분의 응력의 차이가 생겨 셀이 표면이 거칠거나 잘 깨지던 것을 본 고안의 더미 실 구조는 서로의 원판의 표면에서 받는 응력의 차이를 줄이므로 깨짐을 방지하여 불량품을 줄여 단가를 낮출 수 있고, 또한 대형 셀을 제작함에 있어서 큰 효과를 나타내고 있다.Therefore, the dummy seal structure of the present invention is conventionally a portion having a dummy seal in the case of working by lifting the glass of the disc during the scraping operation to remove the cell 26 sealed on the disc glass 24 to a desired size. The difference between the stresses of the missing parts caused the surface of the cell to be rough or cracked. The dummy seal structure of the present invention reduces the difference in the stresses received from the surfaces of the discs of each other. Moreover, it has shown a big effect in manufacturing a large cell.
