Description

디스플레이부 분리방법 및 디스플레이부 분리장치DISPLAY APPARATUS AND DISPLAY APPARATUS
본 발명은 디스플레이부 분리방법 및 디스플레이부 분리장치에 관한 것으로서, 보다 상세하게는 화면표시모듈이 손상되는 것을 방지할 수 있는 디스플레이부 분리방법 및 디스플레이부 분리장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a display unit separation method and a display unit separation apparatus, and more particularly, to a display unit separation method and a display unit separation apparatus capable of preventing a display display module from being damaged.
일반적으로 휴대용 단말기에는 디스플레이부가 설치된다. 디스플레이부는 화면표시모듈과 커버 글라스를 포함한다. 화면표시모듈의 외측면에는 광학점착층에 의해 커버 글라스가 부착된다. 화면표시모듈은 박막트랜지스터, 액정, 컬러필터 및 편광판 등이 적층되어 이루어진다.Generally, a portable terminal has a display unit. The display unit includes a display module and a cover glass. A cover glass is attached to the outer surface of the screen display module by an optical adhesive layer. The screen display module is formed by stacking a thin film transistor, a liquid crystal, a color filter, and a polarizing plate.
화면표시모듈에서 셀 불량이나 화소 불량이 발생되는 경우, 화면표시모듈과 커버 글라스를 분리하여 화면표시모듈과 커버 글라스를 재활용한다. If a cell defect or pixel defect occurs in the display module, separate the display module and cover glass to reuse the display module and cover glass.
그러나, 종래에는 화면표시모듈과 커버 글라스를 고온으로 가열한 후 화면표시모듈에서 커버 글라스를 분리하는 경우, 광학점착층이 분리되지 않고 화면표시모듈 내부의 어느 한 접착층이 분리됨에 따라 화면표시모듈이 손상될 수 있다.However, in the related art, when the cover glass is separated from the screen display module after the display module and the cover glass are heated to a high temperature, the adhesive layer in the display module is separated without separating the optical adhesive layer, It can be damaged.
또한, 저온 상태에서는 화면표시모듈 내부의 접착층의 강도가 커버 글라스의 광학점착층의 강도보다 상대적으로 약하다. 따라서, 화면표시모듈을 저온 상태에서 분리하는 경우, 분리 나이프가 가하는 압력에 의해 화면표시모듈 내부의 어느 한 접착층이 분리됨에 따라 화면표시모듈이 손상될 수 있다.Further, in the low temperature state, the strength of the adhesive layer inside the screen display module is relatively weaker than the strength of the optical adhesive layer of the cover glass. Therefore, when the screen display module is separated from the low temperature state, the display display module may be damaged due to the separation of one adhesive layer in the screen display module by the pressure applied by the separation knife.

또한, 본 발명에 따르면, 안착 스테이지가 공기에 의해 냉각되므로, 디스플레이부가 안착 스테이지의 냉기에 의해 냉각된다. 따라서, 가열부의 열기에 의해 디스플레이부의 화면표시모듈이 가열되는 것을 방지할 수 있다.Further, according to the present invention, since the seating stage is cooled by air, the display portion is cooled by the cold air of the seating stage. Therefore, it is possible to prevent the screen display module of the display unit from being heated by the heating of the heating unit.
또한, 본 발명에 따르면, 디스플레이부가 접착억제장치에서 냉각되므로, 광학접착층이 화면표시모듈에 재점착되는 것을 방지할 수 있다.Further, according to the present invention, since the display portion is cooled in the adhesion suppressing device, it is possible to prevent the optical adhesive layer from being reattached to the display module.
또한, 본 발명에 따르면, 디스플레이부가 냉각지그에 안착된 상태로 글라스 분리장치로 이송되므로, 디스플레이부가 냉각지그에 의해 냉각되면서 이송된다. 따라서, 디스플레이부가 외부 공기와 접촉되더라도 광학접착층이 재점착 가능한 온도로 상승하는 것을 지연시킬 수 있다.Further, according to the present invention, since the display portion is conveyed to the glass separating device while being placed on the cooling jig, the display portion is conveyed while being cooled by the cooling jig. Therefore, even if the display portion is brought into contact with the outside air, it is possible to delay the rise of the optical adhesive layer to the re-stickable temperature.
또한, 본 발명에 따르면, 글라스 분리장치는 기체를 분사하여 광학접착층과 커버 글라스를 분리시키므로, 광학접착층과 커버 글라스가 용이하게 분리될 수 있다.Further, according to the present invention, since the glass separator separates the optical adhesive layer from the cover glass by jetting the gas, the optical adhesive layer and the cover glass can be easily separated.

도 3은 본 발명의 일 실시예에 따른 디스플레이부 분리장치에서 전처리장치를 개략적으로 도시한 구성도이고, 도 4는 본 발명의 일 실시예에 따른 디스플레이부 분리장치의 전처리장치에서 국부 분리부가 광학접착층의 일단부를 국부적으로 분리시킨 상태를 개략적으로 도시한 구성도이다.FIG. 3 is a schematic view illustrating a preprocessing apparatus in a display section separating apparatus according to an embodiment of the present invention, and FIG. 4 is a block diagram of a preprocessing apparatus for a display section separating apparatus according to an embodiment of the present invention. And schematically showing a state in which one end of the adhesive layer is locally separated.
도 3 및 도 4를 참조하면, 전처리장치(110)는 가열부(111), 안착 스테이지(114), 국부 분리부(117)를 포함한다.3 and 4, the pretreatment apparatus 110 includes a heating unit 111, a seating stage 114, and a local separation unit 117.
가열부(111)는 화면표시모듈(11)과 커버 글라스(15)를 접합하는 광학접착층(13)을 국부적으로 가열한다. 화면표시모듈(11)의 터치전극연결부(미도시) 측 단부에는 인쇄회로기판(미도시)에 연결될 전선(미도시)이 연결된다. 터치전극연결부는 카메라(미도시)가 설치될 베젤 영역을 포함한다. The heating unit 111 locally heats the optical adhesive layer 13 joining the screen display module 11 and the cover glass 15. A wire (not shown) to be connected to a printed circuit board (not shown) is connected to the end of the screen display module 11 on the side of the touch electrode connection portion (not shown). The touch electrode connection portion includes a bezel region where a camera (not shown) is to be installed.
가열부(111)는 광학접착층(13)의 단부를 국부적으로 가열하는 가열히터이다. 가열부(111)는 화면표시모듈(11)의 둘레부의 단부를 국부적으로 가열할 수 있도록 화면표시모듈(11)의 폭방향으로 길게 형성된다. 가열부(111)가 광학접착층(13)의 단부를 국부적으로 가열하므로, 가열부(111)의 열기에 의해 화면표시모듈(11)이 가열되는 것을 방지할 수 있다. 따라서, 화면표시모듈(11)의 접착층이 가열부(111)의 열기에 의해 연화되는 것을 방지하므로, 화면표시모듈(11)에서 커버 글라스(15)가 분리될 때에 화면표시모듈(11)이 손상되는 것을 방지할 수 있다.The heating unit 111 is a heating heater for locally heating the end portion of the optical adhesive layer 13. The heating unit 111 is formed to be long in the width direction of the screen display module 11 so that the edge of the periphery of the screen display module 11 can be locally heated. Since the heating unit 111 locally heats the end portion of the optical adhesive layer 13, it is possible to prevent the screen display module 11 from being heated by the heating of the heating unit 111. [ Therefore, since the adhesive layer of the screen display module 11 is prevented from being softened by the heat of the heating unit 111, when the cover glass 15 is separated from the screen display module 11, Can be prevented.
가열부(111)는 광학접착층(13)의 단부에서 5mm 정도만 국부 가열한다. 가열부(111)의 가열 온도는 50-70℃ 범위 내에서 설정된다. 광학접착층(13)이 가열 온도로 가열됨에 따라 광학접착층(13)의 경도를 저하시킬 수 있으므로, 광학접착층(13)이 화면표시모듈(11)에서 용이하게 분리될 수 있다.The heating section 111 heats only about 5 mm at the end of the optical adhesive layer 13 by local heating. The heating temperature of the heating unit 111 is set within the range of 50-70 占 폚. Since the hardness of the optical adhesive layer 13 can be lowered as the optical adhesive layer 13 is heated to the heating temperature, the optical adhesive layer 13 can be easily separated from the screen display module 11. [
이때, 가열부(111)는 광학접착층(13)에서 터치전극연결부 측의 일단부(13a)를 국부적으로 가열한다. 터치전극연결부에는 화면표시모듈(11)의 외곽으로 빛이 투과되는 것을 방지하도록 투과방지 페인트(미도시)가 도포된다. At this time, the heating unit 111 locally heats one end 13a of the optical adhesive layer 13 on the side of the touch electrode connection part. A transparent protective paint (not shown) is applied to the touch electrode connection part to prevent light from being transmitted to an outer periphery of the display module 11. [
안착 스테이지(114)에는 디스플레이부(10)의 상기 커버 글라스(15)가 안착되고, 커버 글라스(15)를 냉각시킨다. 안착 스테이지(114)에는 커버 글라스(15)를 냉각시키도록 에어가 유동되는 냉각라인(116)이 설치된다. 안착 스테이지(114)에는 기판을 진공압에 의해 흡착하도록 복수의 흡착포트(139)가 설치된다.The cover glass 15 of the display unit 10 is seated on the seating stage 114 and the cover glass 15 is cooled. The seating stage 114 is provided with a cooling line 116 through which air flows to cool the cover glass 15. In the seating stage 114, a plurality of suction ports 139 are provided to suction the substrate by vacuum pressure.
국부 분리부(117)는 광학접착층(13)의 가열된 부분과 커버 글라스(15)를 국부적으로 분리시킨다. 국부 분리부(117)가 광학접착층(13)의 가열된 부분과 커버 글라스(15)를 국부적으로 분리시키므로, 화면표시모듈(11)에는 국부 분리부(117)에 의한 외력이 거의 가해지지 않게 된다. 따라서, 광학접착층(13)과 커버 글라스(15)의 국부 분리시 화면표시모듈(11)이 손상되는 것을 방지할 수 있다.The local demultiplexer 117 locally separates the heated portion of the optical adhesive layer 13 and the cover glass 15. The local splitting section 117 locally separates the heated portion of the optical adhesive layer 13 and the cover glass 15 so that the external force by the local splitting section 117 is hardly applied to the screen display module 11 . Therefore, it is possible to prevent the screen display module 11 from being damaged when the optical adhesive layer 13 and the cover glass 15 are locally separated.
국부 분리부(117)는 광학접착층(13)의 가열된 부분과 커버 글라스(15) 사이에 삽입되는 분리 나이프일 수 있다. 분리 나이프는 플랙시블한 얇은 필름으로 제작될 수 있다. 또한, 분리 나이프는 얇은 스테인리스 패널로 제작될 수 있다. 분리 나이프는 화면표시모듈(11)의 손상을 방지할 수 있도록 경도가 낮은 수지재질로 제작될 수 있다. 이러한 분리 나이프는 광학접착층(13)과 커버 글라스(15)를 국부적으로 분리시키는 한 다양한 재질로 제작될 수 있다.The localized part 117 may be a separate knife inserted between the heated part of the optical adhesive layer 13 and the cover glass 15. [ The release knife can be made of a flexible thin film. Also, the separating knife can be made of a thin stainless steel panel. The separation knife may be made of a resin material having a low hardness so as to prevent the display module 11 from being damaged. The separation knife may be made of various materials as long as the optical adhesive layer 13 and the cover glass 15 are locally separated.
또한, 국부 분리부(117)는 광학접착층(13)의 가열된 부분과 커버 글라스(15) 사이에 유체를 분사하는 유체분사 나이프일 수 있다. 유체분사 나이프가 광학접착층(13)과 커버 글라스(15) 사이에 유체를 분사하므로, 광학접착층(13)의 가열된 부분이 유체의 분사압력에 의해 국부적으로 분리될 수 있다. 국부 분리부(117)에서 분사되는 유체는 에어, 질소 등 다양하게 선택될 수 있다.The localized portion 117 may be a fluid ejection knife for ejecting a fluid between the heated portion of the optical adhesive layer 13 and the cover glass 15. [ The fluid injection knife injects the fluid between the optical adhesive layer 13 and the cover glass 15 so that the heated portion of the optical adhesive layer 13 can be locally separated by the injection pressure of the fluid. The fluid ejected from the local separator 117 can be selected in various ways such as air, nitrogen, and the like.

At this time, the display portion 10 is moved to the adhesion suppression device 120 in a state where the local separation portion 117 is inserted into the separated portion of the optical adhesive layer 13 and the cover glass 15. The display unit 10 is moved to the adhesion restraining apparatus 120 in a state where the knife magazine 105 supports the local separating unit 117. Since the display portion 10 is cooled in the adhesion suppressing device 120, it is possible to prevent the locally separated optical adhesive layer 13 from increasing in viscosity so as to have re-adhesion property.
접착억제장치(120)는 냉각챔버(121), 냉각도어(122), 냉각패널부(124) 및 온도조절히터(125)를 포함한다.The adhesion suppression device 120 includes a cooling chamber 121, a cooling door 122, a cooling panel portion 124 and a temperature regulation heater 125.
복수의 냉각챔버(121)는 케이스의 내부에 배열된다. 냉각챔버(121)는 일렬로 배열되거나 복수의 층을 이루도록 배열될 수 있다(도 9 참조).A plurality of cooling chambers 121 are arranged inside the case. The cooling chambers 121 may be arranged in a row or arranged to form a plurality of layers (see FIG. 9).
냉각도어(122)는 복수의 냉각챔버(121)를 각각 개폐시키도록 설치된다. 냉각도어(122)는 냉각챔버(121)마다 하나씩 설치된다.The cooling door 122 is provided to open and close the plurality of cooling chambers 121, respectively. One cooling door 122 is provided for each cooling chamber 121.
냉각패널부(124)는 복수의 냉각챔버(121)에 설치된다. 이때, 케이스에는 하나의 냉각패널부(124)가 설치되고, 냉각패널부(124)의 상면에 복수의 냉각챔버(121)가 배치된다. 따라서, 하나의 냉각패널부(124)가 냉각됨에 따라 복수의 냉각챔버(121)의 내부를 냉각시킬 수 있다.The cooling panel portion 124 is installed in the plurality of cooling chambers 121. At this time, one cooling panel section 124 is provided in the case, and a plurality of cooling chambers 121 are disposed on the upper surface of the cooling panel section 124. Therefore, the inside of the plurality of cooling chambers 121 can be cooled as one cooling panel portion 124 is cooled.
물론, 냉각패널부(124)는 냉각챔버(121)마다 하나씩 설치될 수 있다. 이 경우, 냉각패널부(124)는 개별적으로 냉각 온도가 제어된다.Of course, the cooling panel portions 124 may be installed one by one for each of the cooling chambers 121. In this case, the cooling panel portion 124 is individually controlled at a cooling temperature.
온도조절히터(125)는 복수의 냉각챔버(121)에 각각 설치된다. 이때, 온도조절히터(125)는 복수의 냉각챔버(121)에 대응되도록 냉각패널부(124)에 설치된다. 냉각챔버(121)의 내부 온도가 기 설정된 온도보다 낮아지면, 온도조절히터(125)에 전원이 공급됨에 따라 온도조절히터(125)가 발열되어 냉각챔버(121)의 온도를 기 설정된 온도로 상승시킨다. 따라서, 냉각챔버(121)의 내부 온도가 기 설정된 온도 범위 내에서 일정하게 유지될 수 있다.The temperature control heater 125 is installed in each of the plurality of cooling chambers 121. At this time, the temperature control heater 125 is installed in the cooling panel unit 124 so as to correspond to the plurality of cooling chambers 121. When the internal temperature of the cooling chamber 121 becomes lower than the preset temperature, the temperature adjusting heater 125 generates heat as the power is supplied to the temperature adjusting heater 125 to raise the temperature of the cooling chamber 121 to a predetermined temperature . Therefore, the internal temperature of the cooling chamber 121 can be kept constant within a predetermined temperature range.
냉각챔버(121)의 기 설정된 온도 범위는 영하(-) 55℃ 정도로 설정된다. 이러한 기 설정된 온도 범위는 화면표시모듈(11)이 손상되지 않으면서도 광학접착층(13)이 점착성을 갖지 않도록 방지할 수 있는 온도이다. The predetermined temperature range of the cooling chamber 121 is set to about minus (-) 55 deg. Such a predetermined temperature range is a temperature that can prevent the optical adhesive layer 13 from being tacky without damaging the screen display module 11.
온도조절히터(125)의 둘레부에는 온도조절히터(125)의 열기가 냉각패널부(124)에 전달되는 것을 억제하도록 열교환 차단부(126)가 설치된다. 열교환 차단부(126)가 온도조절히터(125)와 냉각패널부(124) 사이의 열전달을 차단하므로, 냉각패널부(124)의 온도가 정확하게 제어될 수 있다.The heat exchange blocking portion 126 is installed at the periphery of the temperature control heater 125 to prevent the heat of the temperature control heater 125 from being transmitted to the cooling panel portion 124. Since the heat exchange blocking portion 126 blocks the heat transfer between the temperature control heater 125 and the cooling panel portion 124, the temperature of the cooling panel portion 124 can be accurately controlled.
열교환 차단부(126)는 온도조절히터(125)의 둘레부를 둘러싸도록 설치되는 열차단부재일 수 있다. 열차단부재가 온도조절히터(125)와 냉각팬러부 사이의 틈새를 밀봉시키므로, 냉각챔버(121)의 냉기가 외부로 누설되는 것을 방지할 수 있다. The heat exchange blocking portion 126 may be a heat terminal member installed to surround the periphery of the temperature control heater 125. Since the heat insulating member seals the gap between the temperature control heater 125 and the cooling fan portion, it is possible to prevent the cool air in the cooling chamber 121 from leaking to the outside.
또한, 열교환 차단부(126)는 온도조절히터(125)의 둘레부를 둘러싸도록 형성되는 열차단공간일 수 있다. 열차단 공간는 별도의 밀봉부재(미도시)에 의해 밀봉되어 냉각챔버(121)의 냉기가 열차단 공간을 통해 외부로 누설되는 것을 방지할 수 있다.The heat exchange blocking portion 126 may be a heat insulating space formed to surround the periphery of the temperature control heater 125. The heat insulating space can be sealed by a separate sealing member (not shown) to prevent the cold air in the cooling chamber 121 from leaking out through the heat insulating space.
접착억제장치(120)는 냉각챔버(121)의 개구부에 배치되고, 냉각도어(122)의 개방시 냉각챔버(121)에 외부공기가 유입되는 것을 차단하도록 기체커튼을 형성하는 기체커튼 형성부(128)를 더 포함한다. 기체커튼 형성부(128)가 냉각도의 개방시 냉각챔버(121)의 개구부에 기체커튼을 형성하므로, 냉각챔버(121)의 내부에 수분이 침투되는 것을 방지할 수 있다. 기체커튼 형성부(128)는 질소를 분사하여 질소커튼을 형성할 수 있다.The adhesion suppression device 120 is disposed at the opening of the cooling chamber 121 and includes a gas curtain forming part (not shown) for forming a gas curtain to block external air from entering the cooling chamber 121 when the cooling door 122 is opened 128). The gas curtain forming portion 128 forms a gas curtain in the opening portion of the cooling chamber 121 when the cooling degree is opened, so that moisture can be prevented from penetrating into the cooling chamber 121. The gas curtain forming portion 128 can form nitrogen curtain by spraying nitrogen.

도 10 내지 17을 참조하면, 글라스 분리장치(130)는 접착억제장치(120)에서 인출되는 디스플레이부(10)에서 광학접착층(13)과 커버 글라스(15)의 벌어진 틈새로 가스를 분사하여 커버 글라스(15)를 분리시킨다. 광학접착층(13)과 커버 글라스(15)의 벌어진 틈새로 가스를 분사하여 커버 글라스(15)를 분리시키므로, 화면표시모듈(11)에는 가수 분사 압력을 제외한 외력이 거의 가해지지 않는다. 따라서, 커버 글라스(15)를 분리할 때에 화면표시모듈(11)이 손상되는 것을 방지할 수 있다.10 to 17, the glass separating apparatus 130 injects gas into a gap formed between the optical adhesive layer 13 and the cover glass 15 in the display unit 10 drawn out from the adhesion suppressing apparatus 120, The glass 15 is separated. The gas is sprayed to the gap between the optical adhesive layer 13 and the cover glass 15 to separate the cover glass 15 so that external force except for the pressure of the water jetting is hardly applied to the screen display module 11. [ Therefore, it is possible to prevent the screen display module 11 from being damaged when the cover glass 15 is detached.
글라스 분리장치(130)는 냉각지그(131) 및 글라스 분리부(135)를 포함한다.The glass separator 130 includes a cooling jig 131 and a glass separator 135.
냉각지그(131)는 디스플레이부(10)를 냉각시킨다. 디스플레이부(10)가 냉각챔버(121)에서 인출되었을 때에 냉각지그(131)가 디스플레이부(10)를 냉각시키므로, 디스플레이부(10)가 - 45℃에 도달되는 시간을 연장시킬 수 있다. 따라서, 화면표시모듈(11)과 커버 글라스(15)가 분리될 때에 광학접착층(13)이 점착성을 갖도록 온도로 상승되는 것을 지연시킬 수 있으므로, 화면표시모듈(11)에서 커버 글라스(15)를 분리시키는 시간을 충분히 확보할 수 있다.The cooling jig 131 cools the display portion 10. The cooling jig 131 cools the display unit 10 when the display unit 10 is drawn out of the cooling chamber 121 so that the time when the display unit 10 reaches -45 캜 can be prolonged. Therefore, when the screen display module 11 and the cover glass 15 are separated from each other, it is possible to delay the rise of the optical adhesive layer 13 to the temperature so that the optical adhesive layer 13 can stick to the cover glass 15, It is possible to secure a sufficient time for separation.
예를 들면, 냉각지그(131)가 디스플레이부(10)를 냉각시키지 않는 경우, 디스플레이부(10)가 인출 후 대략 8초 정도 경과되면 광학접착층(13)의 온도가 - 45℃ 정도로 상승되어 광학접착층(13)이 점착성을 갖게 된다(도 11 참조). For example, when the cooling jig 131 does not cool the display portion 10, when the display portion 10 has elapsed about 8 seconds after being drawn out, the temperature of the optical adhesive layer 13 is raised to about -45 캜, The adhesive layer 13 becomes sticky (see Fig. 11).
반면, 냉각지그(131)가 디스플레이부(10)를 냉각시키는 경우, 디스플레이부(10)가 인출 후 대략 60초 정도 경과되면 광학접착층(13)의 온도가 - 45℃ 정도로 상승되어 광학접착층(13)이 점착성을 갖게 된다. 따라서, 화면표시모듈(11)에서 커버 글라스(15)를 분리할 수 있는 시간을 충분히 확보할 수 있다(도 12 참조).On the other hand, when the cooling jig 131 cools the display unit 10, when the display unit 10 has elapsed about 60 seconds after the drawing, the temperature of the optical adhesive layer 13 is raised to about -45 캜, ) Has a stickiness. Therefore, it is possible to secure a sufficient time for separating the cover glass 15 from the screen display module 11 (refer to Fig. 12).
글라스 분리부(135)는 디스플레이부(10)에서 광학접착층(13)과 화면표시모듈(11)의 틈새를 벌려주는 분리니들(136)과, 분리니들(136)에 의해 벌려진 틈새에 기체를 분사하여 커버 글라스(15)를 분리시키는 기체분사노즐(137)을 구비한다. 분리니들(136)이 광학접착층(13)과 화면표시모듈(11)의 틈새를 벌려주므로, 기체분사노즐(137)에서 분사되는 기체가 벌려진 틈새로 집중적으로 분사될 수 있다. 따라서, 커버 글라스(15)가 기체의 분사력에 의해 용이하게 분리될 수 있다.The glass separator 135 is provided with a separating needle 136 for opening a gap between the optical adhesive layer 13 and the screen display module 11 in the display unit 10 and a separating needle 136 for injecting a gas into a gap opened by the separating needle 136 And a gas injection nozzle 137 for separating the cover glass 15. Since the separation needle 136 opens the gap between the optical adhesive layer 13 and the screen display module 11, the gas ejected from the gas ejection nozzle 137 can be intensively ejected into the open gap. Therefore, the cover glass 15 can be easily separated by the jetting force of the gas.
글라스 분리장치(130)는 화면표시모듈(11)에서 분리된 커버 글라스(15)를 화면표시모듈(11)의 외측으로 이동시키는 글라스 이동부(138)를 더 포함한다. 이때, 글라스 이동부(138)는 커버 글라스(15)를 흡착한 후 화면표시모듈(11)의 외측으로 반전시킬 수 있다. 글라스 이동부(138)가 커버 글라스(15)를 화면표시모듈(11)의 외측으로 이동시키므로, 화면표시모듈(11)에 잔류된 광학접착층(13)을 용이하게 분리할 수 있다.The glass separating apparatus 130 further includes a glass moving unit 138 for moving the cover glass 15 separated from the screen display module 11 to the outside of the screen display module 11. [ At this time, the glass moving part 138 can reverse the display module 11 to the outside after the cover glass 15 is sucked. Since the glass moving part 138 moves the cover glass 15 to the outside of the screen display module 11, the optical adhesive layer 13 remaining on the screen display module 11 can be easily separated.
글라스 분리장치(130)는 화면표시모듈(11)에 제거비드와 기체를 분사하여 화면표시모듈(11)에 잔류된 광학접착층(13)을 제거하는 접착층 제거부(141)를 더 포함한다. 접착층 제거부(141)가 제거비드와 기체를 분사하여 화면표시모듈(11)에 잔류된 광학접착층(13)을 제거하므로, 광학접착층(13)이 깨끗하게 제거될 수 있다. 또한, 광학접착층(13) 제거시 화면표시모듈(11)에 스크래치가 생기거나 화면표시모듈(11)이 손상되는 것을 방지할 수 있다.The glass separating apparatus 130 further includes an adhesive layer removing unit 141 for removing the optical adhesive layer 13 remaining on the screen display module 11 by spraying a removal bead and a gas onto the screen display module 11. [ The adhesive layer removing part 141 ejects the removed bead and the gas to remove the optical adhesive layer 13 remaining on the screen display module 11 so that the optical adhesive layer 13 can be removed cleanly. It is also possible to prevent the screen display module 11 from being scratched or the screen display module 11 from being damaged when the optical adhesive layer 13 is removed.
제거비드는 드라이아이스 비드일 수 있다. 따라서, 드라이아이스 비드가 광학접착층(13)을 제거한 후 대기 중으로 증발되므로, 제거비드를 수거할 필요가 없다.The removal beads may be dry ice beads. Therefore, since the dry ice beads are evaporated into the air after removing the optical adhesive layer 13, there is no need to collect the removed beads.
글라스 분리장치(130)는 접착층 제거부(141)에 의해 분리되는 광학접착층(13)과 기체를 흡입하는 이물질 흡입부(143)를 더 포함한다. 이물질 흡입부(143)가 분리되는 광학접착층(13)과 기체를 흡입하므로, 분리된 광학접착층(13)이 화면표시모듈(11)에 재점착되는 것을 방지할 수 있다.The glass separating apparatus 130 further includes an optical adhesive layer 13 separated by the adhesive layer removing unit 141 and a foreign matter suction unit 143 for sucking the gas. Since the foreign matter suction part 143 sucks the gas with the optical adhesive layer 13 from which the separated foreign matter suction part 143 is separated, it is possible to prevent the separated optical adhesive layer 13 from being reattached to the screen display module 11. [
글라스 분리장치(130)는 이물질 흡입부(143)에 흡입되는 광학접착층(13)에 액적을 분사하도록 이물질 흡입부(143)에 설치되는 액적 분사부(145)를 더 포함한다. 흡입되는 광학접착층(13)이 액적에 의해 적셔짐에 따라 광학접착층(13)의 점착성을 제거할 수 있다.The glass separator 130 further includes a droplet jetting unit 145 installed in the foreign matter suction unit 143 to jet droplets onto the optical adhesive layer 13 sucked into the foreign matter suction unit 143. The adhesiveness of the optical adhesive layer 13 can be removed as the optical adhesive layer 13 sucked by the droplet is wetted.

The cover glass 15 moved by the glass moving part 138 is seated on the glass seating part 150. That is, the glass moving part 128 inverts the cover glass 15 separated from the screen display module 11, and the inverted cover glass 15 is moved to the glass seating part 150 by a pickup device (not shown) Lt; / RTI > At this time, the cover glass 15 is seated on the glass seating portion 150 such that the optical adhesive layer 13 faces upward.
글라스 안착부(150)에는 커버 글라스(15)가 글라스 안착부(150)에 흡착되도록 진공흡착부(151)가 설치된다. 진공흡착부(151)는 진공압에 의해 커버 글라스(15)를 글라스 안착부(150)에 위치 고정시킨다. 글라스 안착부(150)의 표면은 커버 글라스(15)가 미끄러지는 것을 방지하도록 마찰력이 있은 재질로 형성된다.A vacuum adsorption unit 151 is installed in the glass deposit unit 150 such that the cover glass 15 is adsorbed to the glass deposit unit 150. The vacuum adsorption part 151 fixes the cover glass 15 to the glass seating part 150 by the vacuum pressure. The surface of the glass seating portion 150 is formed of a friction material so as to prevent the cover glass 15 from slipping.
접착층 제거롤러(155)는 글라스 안착부(150)의 폭방향 길이보다 길게 형성된다. 접착층 제거롤러(155)는 롤러회전장치(미도시)와 롤러이송장치(미도시)에 연결된다. 접착층 제거롤러(155)의 표면에는 마찰층(미도시)이 형성된다. 글라스 안착부(150)에 잔류된 광학접착층(13)을 제거하도록 커버 글라스(15)에 밀착된 상태로 회전되면서 이송된다. 접착층 제거롤러(155)가 회전되면서 이송되므로, 커버 글라스(15)에 잔존하는 광학접착층(13)이 접착층 제거롤러(155)에 의해 롤형태로 말리면서 제거된다.The adhesive layer removing roller 155 is formed to be longer than the width direction length of the glass seating portion 150. The adhesive layer removing roller 155 is connected to a roller rotating device (not shown) and a roller feeding device (not shown). A friction layer (not shown) is formed on the surface of the adhesive layer removing roller 155. And is conveyed while being tightly attached to the cover glass 15 so as to remove the optical adhesive layer 13 remaining on the glass seating portion 150.

상기와 같이 구성되는 본 발명의 일 실시예에 따른 디스플레이부 분리방법에 관해 설명하기로 한다.A method of separating a display unit according to an embodiment of the present invention will now be described.
도 22는 본 발명의 일 실시예에 따른 디스플레이부 분리장치의 디스플레이부분리방법을 도시한 플로우 차트이다.FIG. 22 is a flowchart showing a display sub-method of the display sub-separation apparatus according to an embodiment of the present invention.
도 22를 참조하면, 안착 스테이지(114)에 디스플레이부(10)가 안착된다. 이때, 화면표시모듈(11)과 커버 글라스(15)를 접합하는 광학접착층(13)의 단부에 가열부(111)가 대응된다. 또한, 디스플레이부(10)의 커버 글라스(15)가 안착 스테이지(114)의 상면에 접촉된다.Referring to Fig. 22, the display unit 10 is seated on the seating stage 114. Fig. At this time, the heating portion 111 corresponds to the end portion of the optical adhesive layer 13 joining the screen display module 11 and the cover glass 15. Further, the cover glass 15 of the display unit 10 is brought into contact with the upper surface of the seating stage 114.
안착 스테이지(114)의 진공 흡착포트(115)에 의해 디스플레이부(10)가 안착 스테이지(114)의 상면이 흡착된다. 안착 스테이지(114)의 내부에는 공기가 유동됨에 따라 안착 스테이지(114)가 냉각된다.The upper surface of the seating stage 114 is sucked by the display portion 10 by the vacuum suction port 115 of the seating stage 114. As the air flows into the seating stage 114, the seating stage 114 is cooled.
가열부(111)가 구동됨에 따라 디스플레이부(10)에서 화면표시모듈(11)과 커버 글라스(15)를 접합하는 광학접착층(13)이 국부적으로 가열된다(S11). 광학접착층(13)의 일단부(13a)가 가열부(111)의 열기에 의해 국부적으로 가열되므로, 광학접착층(13)의 일단부(13a)의 경도가 감소됨에 따라 광학접착층(13)이 용이하게 분리될 수 있는 상태가 된다. 또한, 화면표시모듈(11)이 가열부(111)의 열기에 의해 거의 가열되지 않으므로, 화면표시모듈(11)이 가열부(111)의 열기에 의해 손상되는 것을 방지할 수 있다.As the heating unit 111 is driven, the optical adhesive layer 13 joining the screen display module 11 and the cover glass 15 on the display unit 10 is locally heated (S11). Since the one end 13a of the optical adhesive layer 13 is locally heated by the heating of the heating part 111 and the hardness of the one end 13a of the optical adhesive layer 13 is reduced, So that it can be separated. In addition, since the screen display module 11 is hardly heated by the heating of the heating unit 111, it is possible to prevent the screen display module 11 from being damaged by the heating of the heating unit 111. [
또한, 안착 스테이지(114)가 공기에 의해 냉각되므로, 디스플레이부(10)가 안착 스테이지(114)의 냉기에 의해 냉각된다. 따라서, 가열부(111)의 열기에 의해 디스플레이부(10)의 화면표시모듈(11)이 가열되는 것을 방지할 수 있다.Further, since the seating stage 114 is cooled by air, the display portion 10 is cooled by the cold air of the seating stage 114. [ Therefore, it is possible to prevent the screen display module 11 of the display unit 10 from being heated by the heating of the heating unit 111.
광학접착층(13)의 가열된 부분과 커버 글라스(15)를 국부적으로 분리시킨다(S12). 이때, 국부 분리부(117)가 분리 나이프인 경우, 국부 분리부(117)가 광학접착층(13)의 가열된 부분과 커버 글라스(15) 사이로 삽입됨에 따라 광학접착층(13)을 국부적으로 분리시킨다. 또한, 국부 분리부(117)가 유체분사 나이프인 경우, 광학접착층(13)의 가열된 부분과 커버 글라스(15) 사이에 유체가 분사됨에 따라 광학접착층(13)을 국부적으로 분리시킨다. The heated portion of the optical adhesive layer 13 and the cover glass 15 are locally separated (S12). At this time, when the local separator 117 is a separating knife, the local separator 117 locally separates the optical adhesive layer 13 as it is inserted between the heated portion of the optical adhesive layer 13 and the cover glass 15 . Further, when the local separation portion 117 is a fluid injection knife, the optical adhesive layer 13 is locally separated as the fluid is injected between the heated portion of the optical adhesive layer 13 and the cover glass 15.
광학접착층(13)의 가열된 부분과 커버 글라스(15)가 국부적으로 분리된 후 디스플레이부(10)와 국부 분리부(117)는 나이프 매거진(105)에 의해 접착억제장치(120)로 이송된다.After the heated portion of the optical adhesive layer 13 and the cover glass 15 are locally separated, the display portion 10 and the local separation portion 117 are transferred to the adhesion suppression device 120 by the knife magazine 105 .
디스플레이부(10)를 접착억제장치(120)에 투입하여 냉각시킨다(S13). 이때, 냉각지그(131)는 냉각지그 안착부(103)에 대기되고, 광학접착층(13)이 국부 분리된 디스플레이부(10)가 안착 스테이지(114)에서 냉각지그(131)로 나이프 매거진(105)에 의해 이송된다. 디스플레이부(10)가 냉각지그(131)에 안착되면, 냉각도어(122)가 개방된 후 냉각챔버(121)의 내부에 디스플레이부(10)가 안착된 냉각지그(131)가 투입된다. 이때, 디스플레이부(10)의 화면표시모듈(11)이 냉각지그(131)의 상면에 접촉된다. 냉각도어(122)가 닫힘에 따라 냉각챔버(121)의 내부에서 디스플레이부(10)가 냉각된다. 디스플레이부(10)가 냉각챔버(121)에서 냉각되므로, 광학접착층(13)이 화면표시모듈(11)에 재점착되는 것을 방지할 수 있다.The display unit 10 is put into the adhesion suppression apparatus 120 and cooled (S13). At this time, the cooling jig 131 stands by in the cooling jig seating part 103 and the display part 10 in which the optical adhesive layer 13 is locally separated is moved from the seating stage 114 to the cooling jig 131, . When the display unit 10 is mounted on the cooling jig 131, the cooling jig 131 having the display unit 10 mounted therein is inserted into the cooling chamber 121 after the cooling door 122 is opened. At this time, the screen display module 11 of the display unit 10 is brought into contact with the upper surface of the cooling jig 131. As the cooling door 122 is closed, the display portion 10 is cooled inside the cooling chamber 121. Since the display portion 10 is cooled in the cooling chamber 121, it is possible to prevent the optical adhesive layer 13 from being reattached to the screen display module 11. [
냉각패널부(124)가 구동됨에 따라 냉각챔버(121)의 내부는 기 설정된 온도, 예를 들면 - 55℃ 정도의 온도로 유지된다. 또한, 각 냉각챔버(121)에는 냉각챔버(121)의 온도를 측정할 수 있도록 온도센서가 설치된다. 냉각챔버(121)가 기 설정된 온도보다 낮은 온도로 냉각되면, 온도조절히터(125)를 구동시켜 냉각챔버(121)의 온도를 기 설정된 온도로 증가시킨다. 냉각챔버(121)가 다시 기 설정된 온도에 도달되면, 온도조절히터(125)에 공급되는 전원을 차단한다. 따라서, 냉각챔버(121)는 온도조절히터(125)의 온오프 제어에 의해 기 설정된 온도 범위로 유지될 수 있다.As the cooling panel section 124 is driven, the inside of the cooling chamber 121 is maintained at a predetermined temperature, for example, about -55 ° C. Further, a temperature sensor is installed in each cooling chamber 121 so that the temperature of the cooling chamber 121 can be measured. When the cooling chamber 121 is cooled to a temperature lower than a predetermined temperature, the temperature adjusting heater 125 is driven to increase the temperature of the cooling chamber 121 to a predetermined temperature. When the cooling chamber 121 again reaches a predetermined temperature, the power supplied to the temperature control heater 125 is cut off. Therefore, the cooling chamber 121 can be maintained in a predetermined temperature range by on-off control of the temperature control heater 125. [
온도조절히터(125)는 냉각패널부(124)에 복수개 설치되고, 온도조절히터(125)의 둘레에는 냉각패널부(124)와 열교환되는 것을 방지하도록 열교환 차단부(126)가 설치된다. 열교환 차단부(126)는 온도조절히터(125)의 열기가 냉각패널부(124)에 전달되는 것을 방지한다.A plurality of temperature control heaters 125 are provided on the cooling panel unit 124 and a heat exchange blocking unit 126 is installed around the temperature control heaters 125 to prevent heat exchange with the cooling panel unit 124. The heat exchange blocking portion 126 prevents the heat of the temperature control heater 125 from being transmitted to the cooling panel portion 124.
접착억제장치(120)의 냉각챔버(121)에서 디스플레이부(10)를 인출한다(S14). 이때, 냉각도어(122)가 개방되면, 디스플레이부(10)가 도어의 개방과 동시에 냉각챔버(121)의 외부로 인출된다. 이때, 디스플레이부(10)는 냉각지그(131)에 안착된 상태로 인출된다. 디스플레이부(10)의 화면표시모듈(11)이 냉각지그(131)의 상면에 접촉되고, 커버 글라스(15)는 상측을 향하도록 배치된다.The display unit 10 is taken out of the cooling chamber 121 of the adhesion suppression apparatus 120 (S14). At this time, when the cooling door 122 is opened, the display unit 10 is drawn out of the cooling chamber 121 simultaneously with opening of the door. At this time, the display unit 10 is taken out in a state of being seated in the cooling jig 131. The screen display module 11 of the display unit 10 is brought into contact with the upper surface of the cooling jig 131 and the cover glass 15 is arranged with the upward direction.
냉각도어(122)가 개방될 때에 기체커튼 형성부(128)는 냉각챔버(121)의 개구부에 기체를 분사하여 기체커튼을 형성한다(S15). 이때, 기체로는 질소가스가 적용될 수 있다. 기체커튼은 외부 공기가 냉각챔버(121)의 내부로 유입되는 것을 차단한다. 따라서, 냉각챔버(121)의 내측면에 습기나 성애가 끼는 것을 방지할 수 있다. When the cooling door 122 is opened, the gas curtain forming portion 128 forms a gas curtain by blowing gas into the opening of the cooling chamber 121 (S15). At this time, nitrogen gas may be applied to the gas. The gas curtain blocks external air from entering the interior of the cooling chamber (121). Therefore, it is possible to prevent the inside surface of the cooling chamber 121 from being caught in moisture or sexual intercourse.
디스플레이부(10)가 안착된 냉각지그(131)는 지그 이송장치(미도시)에 의해 글라스 분리장치(130)로 이송된다. 글라스 분리장치(130)는 냉각지그(131), 글라스 분리부(135) 및 글라스 이동부(138)를 포함한다. 디스플레이부(10)가 냉각지그(131)에 안착된 상태로 글라스 분리장치(130)로 이송되므로, 디스플레이부(10)가 냉각지그(131)에 의해 냉각되면서 이송된다. 따라서, 디스플레이부(10)가 외부 공기와 접촉되더라도 광학접착층(13)이 재점착 가능한 온도로 상승될 때까지는 대략 60초 정도 걸리게 된다. 따라서, 디스플레이부(10)가 냉각챔버(121)에서 배출된 후 광학접착층(13)이 재점착 온도에 도달되기 이전에 커버 글라스(15)를 분리할 수 있다. 디스플레이부(10)가 냉각챔버(121)에서 배출된 후 커버 글라스(15)의 분리 완료시까지는 60초보다 현저히 짧은 시간이 소요된다.The cooling jig 131 on which the display unit 10 is mounted is transferred to the glass separator 130 by a jig transfer device (not shown). The glass separating apparatus 130 includes a cooling jig 131, a glass separating unit 135, and a glass moving unit 138. The display unit 10 is transferred to the glass separating apparatus 130 while being placed on the cooling jig 131 so that the display unit 10 is cooled while being cooled by the cooling jig 131. Therefore, even if the display portion 10 is brought into contact with the outside air, it takes about 60 seconds until the optical adhesive layer 13 is raised to a re-adhesive temperature. Therefore, the cover glass 15 can be separated before the optical adhesive layer 13 reaches the re-adhesion temperature after the display portion 10 is discharged from the cooling chamber 121. [ It takes a considerably shorter time than 60 seconds until the display unit 10 is discharged from the cooling chamber 121 and the cover glass 15 is completely removed.
글라스 분리장치(130)에서는 광학접착층(13)과 커버 글라스(15)의 분리된 틈새로 기체를 분사하여 광학접착층(13)과 커버 글라스(15)를 분리시킨다(S16). 기체를 분사하여 광학접착층(13)과 커버 글라스(15)를 분리시키므로, 광학접착층(13)과 커버 글라스(15)가 용이하게 분리될 수 있다. 기체로는 에어를 제시한다.The glass separator 130 separates the optical adhesive layer 13 and the cover glass 15 by spraying gas with the separated gaps between the optical adhesive layer 13 and the cover glass 15 (S16). The optical adhesive layer 13 and the cover glass 15 are separated from each other by jetting the gas so that the optical adhesive layer 13 and the cover glass 15 can be easily separated. The air presents the air.
이때, 광학접착층(13)과 커버 글라스(15)의 분리된 틈새에 분리니들(136)을 삽입하여 틈새 간격을 벌려주고, 광학접착층(13)과 커버 글라스(15)의 벌려진 틈새에 기체분사노즐(137)이 기체를 분사하여 광학접착층(13)과 커버 글라스(15)를 분리시킨다. 분리니들(136)이 광학접착층(13)과 커버 글라스(15)의 틈새를 벌려주므로, 기체분사노즐(137)에서 분사되는 기체가 틈새에 집중적으로 분사될 수 있다. 따라서, 광학접착층(13)과 커버 글라스(15)가 보다 용이하게 분리되고, 화면표시모듈(11)이 손상되는 것을 방지할 수 있다. 또한, 광학접착층(13)과 커버 글라스(15)의 분리 속도가 빨라지므로, 광학접착층(13)이 분사되는 기체와 마찰됨에 따라 재점착 온도로 상승되는 것을 방지할 수 있다. 따라서, 분리된 광학접착층(13)에 화면표시모듈(11)에 재점착되는 것을 방지할 수 있다.At this time, the separation needles 136 are inserted into the separated gaps between the optical adhesive layer 13 and the cover glass 15 to enlarge the gap between the optical adhesive layer 13 and the cover glass 15, (137) blows gas to separate the optical adhesive layer (13) and the cover glass (15). Since the separation needle 136 opens the gap between the optical adhesive layer 13 and the cover glass 15, the gas injected from the gas injection nozzle 137 can be intensively injected into the gap. Therefore, the optical adhesive layer 13 and the cover glass 15 can be separated more easily, and the display module 11 can be prevented from being damaged. Further, since the separation speed between the optical adhesive layer 13 and the cover glass 15 is increased, it is possible to prevent the optical adhesive layer 13 from rising to the re-adhesion temperature as it rubs against the gas to be injected. Therefore, it is possible to prevent the optical adhesive layer 13 from being reattached to the screen display module 11.
광학접착층(13)과 커버 글라스(15)가 분리될 때에 화면표시모듈(11)은 냉각지그(131)의 진공라인(133)에 의해 흡착되므로, 화면표시모듈(11)과 커버 글라스(15)가 분리니들(136)의 가압력과 기체의 분사압력에 의해 냉각지그(131)에서 움직이는 것을 방지할 수 있다.The screen display module 11 and the cover glass 15 are attracted by the vacuum line 133 of the cooling jig 131 when the optical adhesive layer 13 and the cover glass 15 are separated. Can be prevented from moving in the cooling jig (131) by the pressing force of the separation needle (136) and the gas injection pressure.
광학접착층(13)과 커버 글라스(15)가 화면표시모듈(11)에서 완전히 분리된 후 글라스 이동부(138)가 커버 글라스(15)를 화면표시모듈(11)의 외측으로 이동시킨다(S17). 글라스 이동부(138)는 커버 글라스(15)를 흡착한 후 화면표시모듈(11)의 외측으로 반전시킨다. 글라스 이동부(138)에는 커버 글라스(15)를 흡착하도록 흡착포트(115)가 형성된다.The glass moving part 138 moves the cover glass 15 to the outside of the screen display module 11 after the optical adhesive layer 13 and the cover glass 15 are completely separated from the screen display module 11 (S17) . The glass moving part 138 sucks the cover glass 15 and then reverses it to the outside of the screen display module 11. A suction port (115) is formed in the glass moving part (138) to absorb the cover glass (15).
화면표시모듈(11)에 잔류된 광학접착층(13)이 제거된다(S18). 이때, 접착층 제거부(141)가 화면표시모듈(11)에 제거비드와 기체를 분사하여 화면표시모듈(11)에서 광학접착층(13)을 제거한다. 제거비드는 드라이아이스 비드이므로, 제거비드가 광학접착층(13)을 제거한 후에는 공기 중으로 증발된다. 따라서, 화면표시모듈(11)에서 제거비드를 회수하거나 청소할 필요가 없다. 또한, 제거비드와 기체의 분사력을 제외하고 화면표시모듈(11)에 물리적인 압력이 거의 가해지지 않으므로, 화면표시모듈(11)이 손상되는 것을 방지할 수 있다. 또한, 제거비드가 광학접착층(13)을 타격하여 제거하므로, 화면표시모듈(11)에서 광학접착층(13)이 깨끗하게 제거될 수 있다.The optical adhesive layer 13 remaining on the screen display module 11 is removed (S18). At this time, the adhesive layer removing unit 141 ejects the removal beads and the gas to the screen display module 11 to remove the optical adhesive layer 13 from the screen display module 11. [ Since the removal beads are dry ice beads, the removal beads evaporate into the air after the optical adhesive layer 13 is removed. Therefore, the screen display module 11 does not need to collect or clean the removed beads. In addition, since physical pressure is hardly applied to the screen display module 11 except for the ejection force of the removed bead and the gas, it is possible to prevent the screen display module 11 from being damaged. Further, since the removal beads strike the optical adhesive layer 13 and remove it, the optical adhesive layer 13 can be removed from the screen display module 11 cleanly.
이물질 흡입부(143)가 화면표시모듈(11)에서 제거되는 광학접착층(13)을 흡입한다(S19). 이물질 흡입부(143)는 화면표시모듈(11)에서 접착층 제거부(141)에 분사방향에 대향되게 배치된다. 이물질 흡입부(143)는 접착층 제거부(141)와 일정 간격 이격된 상태에서 접착층 제거부(141)와 함께 이동되면서 제거되는 광학접착층(13)과 기체를 흡입한다. 이물질 흡입부(143)가 제거되는 광학접착층(13)을 흡입하므로, 제거되는 광학접착층(13)이 온도 상승되어 화면표시모듈(11)이나 주변 구조물에 재점착되는 것을 방지할 수 있다.The foreign matter suction unit 143 sucks the optical adhesive layer 13 removed from the screen display module 11 (S19). The foreign matter suction unit 143 is disposed in the screen display module 11 so as to face the adhesive layer removal unit 141 in the spray direction. The foreign matter suction unit 143 sucks the gas and the optical adhesive layer 13, which is removed while moving together with the adhesive layer removing unit 141 in a state of being spaced apart from the adhesive layer removing unit 141 by a predetermined distance. Since the foreign substance suction part 143 sucks the optical adhesive layer 13 from which the foreign substance suction part 143 is removed, it is possible to prevent the optical adhesive layer 13 from being re-adhered to the screen display module 11 or the peripheral structure.
액적 분사부(145)에서는 이물질 흡입부(143)에 흡입되는 광학접착층(13)에 액적을 분사한다(S20). 흡입되는 광학접착층(13)에 액적을 분사하므로, 액적에 의해 광학접착층(13)의 재점착성이 제거된다. 따라사, 흡입되는 광학접착층(13)이 액적 분사부(145)의 내부에서 재점착되는 것을 방지할 수 있다.In the droplet jetting unit 145, droplets are jetted onto the optical adhesive layer 13 sucked into the foreign matter suction unit 143 (S20). Since the droplets are jetted onto the optical adhesive layer 13 to be sucked, the repacking property of the optical adhesive layer 13 is removed by the droplet. Adhesion of the optical adhesive layer 13 to be sucked in the droplet jetting section 145 can be prevented.
상기한 과정을 통해 분리된 화면표시모듈(11)과 커버 글라스(15)는 세정장치(107)로 이송된 후 세정되고, 배출장치(108)로 배출된다.The screen display module 11 and the cover glass 15 separated through the above process are transferred to the cleaning device 107 and then cleaned and discharged to the discharge device 108.
또한, 글라스 분리장치(130)에서 화면표시모듈(11)과 커버 글라스(15)가 이송되면, 글라스 분리장치(130)에 위치된 냉각지그(131)는 냉각지그 이송부(미도시)에 의해 다시 냉각지그 안착부(103)로 복귀된다. 복수의 냉각지그(131)가 냉각지그 안착부(103)와 글라스 분리장치(130) 사이의 구간을 순환 이동됨에 따라 디스플레이부(10)의 분리 공정이 계속적으로 진행될 수 있다.When the screen display module 11 and the cover glass 15 are transferred from the glass separating apparatus 130, the cooling jig 131 located in the glass separating apparatus 130 is returned again by the cooling jig transferring unit And returned to the cooling jig seat 103. The separation process of the display unit 10 can be continuously performed as the plurality of cooling jigs 131 are circularly moved in the section between the cooling jig receiving unit 103 and the glass separator 130.
한편, 글라스 이동부(128)에 의해 반전된 커버 글라스(15)를 픽업장치(미도시)로 픽업한 후 글라스 안착부(150)에 안착시킨다. 이때, 커버 글라스(15)는 광합접착층(13)이 형성된 면이 상측을 향하도록 글라스 안착부(150)에 안착된다.On the other hand, the cover glass 15 inverted by the glass moving part 128 is picked up by a pick-up device (not shown), and then put on the glass seating part 150. At this time, the cover glass 15 is seated on the glass seating portion 150 such that the surface on which the photo-integrating adhesive layer 13 is formed faces upward.
진공흡착부(151)가 구동되면, 진공흡착부(151)의 진공압에 의해 커버 글라스(15)가 글라스 안착부(150)에서 안착된다. 또한, 커버 글라스(15)는 글라스 안착부(150)에 마찰됨에 따라 이동되지 않도록 고정된다.When the vacuum suction part 151 is driven, the cover glass 15 is seated in the glass receiving part 150 by the vacuum pressure of the vacuum suction part 151. Further, the cover glass 15 is fixed so as not to move as it is rubbed against the glass seating portion 150.
커버 글라스(15)에 잔류된 광학접착층(13)을 제거한다(S21). 이때, 접착층 제거롤러(155)가 하강하여 커버 글라스(15)의 상면에 밀착된다. 이어, 접착층 제거롤러(155)가 회전되면서 재점착 방지판(153) 측으로 이동되어 커버 글라스(15)에 잔류된 광학접착층(13)을 제거한다(S21). 이때, 광학접착층(13)은 접착층 제거롤러(155)에 밀림에 의해 롤형태로 말리면서 제거된다. 제거된 광학접착층(13)은 접착층 제거롤러(155)에 밀려 재점착 방지판(13)으로 이동된다.The optical adhesive layer 13 remaining on the cover glass 15 is removed (S21). At this time, the adhesive layer removing roller 155 is lowered and brought into close contact with the upper surface of the cover glass 15. Then, the adhesive layer removing roller 155 is rotated and moved to the side of the re-adhesion preventing plate 153 to remove the optical adhesive layer 13 remaining in the cover glass 15 (S21). At this time, the optical adhesive layer 13 is curled to the adhesive layer removing roller 155 to be dried while being rolled. The removed optical adhesive layer 13 is pushed by the adhesive layer removing roller 155 and moved to the re-adhesion preventive plate 13.
제거된 광학접착층(13)을 접착층 배출통(157)에 배출한다(S22). 이때, 접착층 배출노즐(156)에서 제거된 광학접착층(13)에 에어를 분사하여 접착층 배출통(157)에 광학접착층(13)이 배출되게 한다. 접착층 배출통(157)에 광학접착층(13)이 배출되므로, 광학접착층(13)이 재점착 방지판(153)이나 글라스 안착부(150)에 재점착되는 것을 방지할 수 있다.The removed optical adhesive layer 13 is discharged to the adhesive layer discharge cylinder 157 (S22). At this time, air is jetted to the optical adhesive layer 13 removed from the adhesive layer discharge nozzle 156 so that the optical adhesive layer 13 is discharged to the adhesive layer discharge cylinder 157. The optical adhesive layer 13 is discharged to the adhesive layer discharge cylinder 157 so that the optical adhesive layer 13 can be prevented from being reattached to the reattaching plate 153 or the glass seating portion 150. [
상기와 같이, 광학접착층(13)의 일단부(13a)가 가열부(111)의 열기에 의해 국부적으로 가열되므로, 광학접착층(13)의 일단부(13a)의 경도가 감소됨에 따라 광학접착층(13)이 용이하게 분리될 수 있는 상태가 된다. 또한, 화면표시모듈(11)이 가열부(111)의 열기에 의해 거의 가열되지 않으므로, 화면표시모듈(11)이 가열부(111)의 열기에 의해 손상되는 것을 방지할 수 있다.Since the one end portion 13a of the optical adhesive layer 13 is locally heated by the heating of the heating portion 111 as described above, the hardness of the one end portion 13a of the optical adhesive layer 13 is reduced, 13) can be easily separated. In addition, since the screen display module 11 is hardly heated by the heating of the heating unit 111, it is possible to prevent the screen display module 11 from being damaged by the heating of the heating unit 111. [
또한, 안착 스테이지(114)가 공기에 의해 냉각되므로, 디스플레이부(10)가 안착 스테이지(114)의 냉기에 의해 냉각된다. 따라서, 가열부(111)의 열기에 의해 디스플레이부(10)의 화면표시모듈(11)이 가열되는 것을 방지할 수 있다.Further, since the seating stage 114 is cooled by air, the display portion 10 is cooled by the cold air of the seating stage 114. [ Therefore, it is possible to prevent the screen display module 11 of the display unit 10 from being heated by the heating of the heating unit 111.
또한, 디스플레이부(10)가 접착억제장치(120)에서 냉각되므로, 광학접착층(13)이 화면표시모듈(11)에 재점착되는 것을 방지할 수 있다.In addition, since the display portion 10 is cooled in the adhesion suppressing device 120, it is possible to prevent the optical adhesive layer 13 from being reattached to the screen display module 11. [
또한, 디스플레이부(10)가 냉각지그(131)에 안착된 상태로 글라스 분리장치(130)로 이송되므로, 디스플레이부(10)가 냉각지그(131)에 의해 냉각되면서 이송된다. 따라서, 디스플레이부(10)가 외부 공기와 접촉되더라도 광학접착층(13)이 재점착 가능한 온도로 상승하는 것을 지연시킬 수 있다.The display unit 10 is conveyed while being cooled by the cooling jig 131 because the display unit 10 is transferred to the glass separator 130 while being placed on the cooling jig 131. Therefore, even when the display portion 10 is in contact with the outside air, it is possible to delay the rise of the optical adhesive layer 13 to a re-stickable temperature.
또한, 글라스 분리장치(130)는 기체를 분사하여 광학접착층(13)과 커버 글라스(15)를 분리시키므로, 광학접착층(13)과 커버 글라스(15)가 용이하게 분리될 수 있다.The glass separator 130 separates the optical adhesive layer 13 and the cover glass 15 by jetting the gas so that the optical adhesive layer 13 and the cover glass 15 can be easily separated.
