Description
本發明係有關液晶面板的除電裝置。 The present invention relates to a static elimination device for a liquid crystal panel.
液晶顯示器，作為平面顯示器的一種係受到廣泛使用。又，液晶面板為液晶顯示器的重要零件。在液晶面板製造的後期階段工程中，偏光膜等光學膜會被貼附於液晶面板的兩面。通常，光學膜是以隔著黏著劑層而層積有載具膜(carrier film)的形態下供給，在貼附至液晶面板時，該載具膜會在使黏著劑層殘留於光學膜側的狀態下被剝離，而光學膜隔著黏著劑層貼附於液晶面板。然而，光學膜的貼附過程及載具膜的剝離過程中，由於載具膜的摩擦帶電及剝離帶電，液晶面板全體會帶有靜電。該靜電帶電會妨礙光學檢査裝置的正常檢査，且液晶面板恐會被靜電破壞，影響正常的生產稼動。 Liquid crystal displays, which are widely used as a type of flat panel display, are widely used. Moreover, the liquid crystal panel is an important part of the liquid crystal display. In the later stage of the manufacture of the liquid crystal panel, an optical film such as a polarizing film is attached to both sides of the liquid crystal panel. Usually, the optical film is supplied in a form in which a carrier film is laminated via an adhesive layer, and when attached to a liquid crystal panel, the carrier film leaves the adhesive layer on the optical film side. In the state of being peeled off, the optical film is attached to the liquid crystal panel via the adhesive layer. However, during the attaching process of the optical film and the peeling process of the carrier film, the liquid crystal panel is electrostatically charged as a whole due to frictional charging and peeling of the carrier film. The electrostatic charging may hinder the normal inspection of the optical inspection device, and the liquid crystal panel may be destroyed by static electricity, which may affect normal production operations.
日本特開2013-4274號公報中提出一種技術，是在生產工程中，令顯示器面板停止於除電裝置的下方，並使除電裝置之導電性構件與貼附於顯示器面板之功 能性膜片的端部接觸規定時間，藉此除去前一工程中產生之靜電帶電。 Japanese Laid-Open Patent Publication No. 2013-4274 proposes a technique in which a display panel is stopped under a static elimination device in a production process, and a conductive member of the static elimination device and a work attached to the display panel are attached. The end of the energy film is brought into contact for a predetermined time, thereby removing the electrostatic charging generated in the previous process.
此外，日本特開2012-3897號公報中提出一種技術，是使除電刷與基板的端子電極部接觸，以除去靜電帶電。若要具體敍述，是在生產線中，例如令液晶面板停止於除電裝置的前方的位置之後，藉由使除電刷移動之移動機構，以和基板表面呈傾斜的方式使除電刷與端子電極部接觸，來除去靜電，防止基板的電路零件的破壞。 Further, Japanese Laid-Open Patent Publication No. 2012-3897 proposes a technique in which a static eliminating brush is brought into contact with a terminal electrode portion of a substrate to remove electrostatic charging. To be specifically described, in the production line, for example, after the liquid crystal panel is stopped at the position in front of the static eliminating device, the removing brush is brought into contact with the terminal electrode portion in a manner inclined to the surface of the substrate by moving the removing mechanism of the removing brush. To remove static electricity and prevent damage to the circuit components of the substrate.
然而，上述習知技術，存在著以下問題。首先，除電中，由於除電構件僅接觸面板的一端部或端子電極部，因此接觸面積受限，無法有效地除去面板表面全體的靜電帶電。此外，它們是於除電中令面板停止搬運，而在停止的面板進行除電，除電過程本身亦需花費一定程度的時間，因此生產線的稼動率會降低。又，上述這樣的除電裝置，必須有用來使除電構件正確地移動至目標位置之移動機構及對位機構，因此除電裝置本身的構造變得複雜，生產成本變高。 However, the above conventional techniques have the following problems. First, in the static elimination, since the static eliminating member contacts only one end portion of the panel or the terminal electrode portion, the contact area is limited, and the electrostatic charging of the entire panel surface cannot be effectively removed. In addition, they stop the handling of the panel during the de-energization, and the static elimination process takes a certain amount of time, so the production rate of the production line is reduced. Further, in the above-described static eliminating device, since the moving mechanism and the positioning mechanism for accurately moving the static eliminating member to the target position are required, the structure of the static eliminating device itself is complicated, and the production cost is increased.
本發明係有鑑於上述問題而研發，目的在於提供一種除電裝置，其於除電過程中能夠與液晶面板表面全體接觸，於除電中不需停止液晶面板的搬運，且除電裝置本身的構造非常簡單。 The present invention has been made in view of the above problems, and an object thereof is to provide a static eliminating device which can be in contact with the entire surface of a liquid crystal panel during a static elimination process, and does not need to stop the transportation of the liquid crystal panel during the static elimination, and the structure of the static eliminating device itself is very simple.

The second holding means and the second static eliminating means held by the second holding means are disposed in contact with each of the terminal regions on both sides in the conveyance path direction of the liquid crystal panel.
按照本發明的該態樣之液晶面板的除電裝置，於除電過程中，和沿著液晶面板的搬運路徑方向的兩側之端子區域的接觸面積及接觸時間會大幅增加，因此對於搬運中的液晶面板能夠確保充分的除電。 According to the static eliminator of the liquid crystal panel of the aspect of the present invention, the contact area and the contact time of the terminal regions on both sides along the direction of the transport path of the liquid crystal panel are greatly increased during the erasing process, and thus the liquid crystal during transport is carried out. The panel ensures adequate power removal.
按照本發明之較佳態樣，液晶面板的除電裝置中，一對第2除電單元係設置成，能夠沿著液晶面板的寬度方向調整對於前述第1除電單元的固定位置。 According to a preferred embodiment of the present invention, in the static eliminator of the liquid crystal panel, the pair of second static eliminating units are provided so that the fixing position to the first static eliminating unit can be adjusted along the width direction of the liquid crystal panel.
按照這樣構成之液晶面板的除電裝置，能夠因應尺寸相異之液晶面板而於液晶面板的寬度方向設置第2除電單元的位置，能夠彈性地因應各種型式及尺寸的液晶面板的除電。 According to the liquid-removal device of the liquid crystal panel having the above-described configuration, the position of the second static eliminating unit can be set in the width direction of the liquid crystal panel in accordance with the liquid crystal panel having different sizes, and the liquid-removal of the liquid crystal panel of various types and sizes can be flexibly responded to.

按照這樣配置之液晶面板的除電裝置，藉由將除電裝置設置於光學膜貼附裝置之後，可防止在除電裝置產生的異物對光學膜的貼附造成問題，且藉由除電裝置設於光學檢査裝置之前，可消弭靜電對於光學檢査裝置的檢査之影響。 According to the static eliminator of the liquid crystal panel thus disposed, after the static eliminator is disposed in the optical film attaching device, it is possible to prevent the problem that the foreign matter generated by the static eliminator is attached to the optical film, and the optical device is provided for the optical inspection. Before the device, the influence of static electricity on the inspection of the optical inspection device can be eliminated.

第1除電單元CD20，沿著和搬運路徑方向正交之方向(亦即液晶面板100的寬度方向)而設置於搬運單元CD10的上方，包含沿著液晶面板100的寬度方向而固定於搬運單元框架CD11之第1保持機構CD21、及被第1保持機構CD21保持之第1除電機構CD22。 The first static eliminating unit CD20 is disposed above the transport unit CD10 in a direction orthogonal to the direction of the transport path (that is, the width direction of the liquid crystal panel 100), and is fixed to the transport unit frame along the width direction of the liquid crystal panel 100. The first holding mechanism CD21 of the CD 11 and the first static eliminating mechanism CD22 held by the first holding mechanism CD21.
第1保持機構CD21，例如為導電性良好的金屬托架，藉由螺絲201等緊固機構而固定於搬運單元框架 CD11，透過搬運單元框架CD11成為接地狀態。 The first holding mechanism CD21 is, for example, a metal bracket having good electrical conductivity, and is fixed to the transport unit frame by a fastening mechanism such as a screw 201. The CD 11 is grounded through the transport unit frame CD11.
如圖4A所示，第1除電機構CD22，由第1導電刷CD221及第1導電刷托座CD222所構成。第1導電刷CD221，由導電率108~1012Ω/□之導電性纖維材料所成，藉由在第1導電刷托座CD222的上部以相同間隔排列之螺絲201等鎖固機構，而被夾持於由金屬所成之第1導電刷托座CD222。因此，第1導電刷CD221與第1導電刷托座CD222係電性連接。 As shown in FIG. 4A, the first static eliminating mechanism CD22 is composed of a first conductive brush CD221 and a first conductive brush holder CD222. The first conductive brush CD221 is made of a conductive fiber material having a conductivity of 10 8 to 10 12 Ω/□, and is locked by a screw 201 or the like which is arranged at the same interval on the upper portion of the first conductive brush holder CD222. It is clamped to the first conductive brush holder CD222 made of metal. Therefore, the first conductive brush CD221 is electrically connected to the first conductive brush holder CD222.
如圖3B所示，第1除電機構CD22，藉由螺絲201而固定於第1保持機構CD21。因此，第1導電刷CD221，透過第1導電刷CD222、第1保持機構CD21、搬運單元框架CD11而被接地。 As shown in FIG. 3B, the first neutralization mechanism CD22 is fixed to the first holding mechanism CD21 by a screw 201. Therefore, the first conductive brush CD221 is grounded through the first conductive brush CD222, the first holding mechanism CD21, and the transport unit frame CD11.
第1導電刷CD221的長度，雖是依據實際情況來決定，但一般而言被設定在400~1200mm左右。如圖3C所示，第1導電刷CD221的長度只要比液晶面板100的寬度方向的長度還大即可。第1保持機構CD21中的第1除電機構CD22的位置係被設定成，搬運中的液晶面板100能夠在其寬度全體的範圍內與第1除電機構CD22接觸。因此，當液晶面板100於搬運中通過除電裝置CD時，第1導電刷CD221會接觸液晶面板100的寬度全體範圍內的表面。如圖3D所示，隨著液晶面板100被搬運而通過除電裝置，第1導電刷CD221會從液晶面板100的長度方向先端開始與液晶面板100接觸，直到離開液晶面板100的長度方向末端為止保持接觸。因此，在液 晶面板100通過除電裝置的過程中，第1導電刷CD221能夠與液晶面板100的表面全體接觸，存在於液晶面板100的表面及2個寬度方向的端子區域之靜電，會透過第1導電刷CD221、第1導電刷托座CD222、第1保持機構CD21、搬運單元框架CD11而流出，藉此被除去。 Although the length of the first conductive brush CD221 is determined depending on the actual situation, it is generally set to about 400 to 1200 mm. As shown in FIG. 3C, the length of the first conductive brush CD221 may be larger than the length of the liquid crystal panel 100 in the width direction. The position of the first neutralization mechanism CD22 in the first holding mechanism CD21 is set such that the liquid crystal panel 100 being conveyed can come into contact with the first neutralization mechanism CD22 over the entire width thereof. Therefore, when the liquid crystal panel 100 passes through the static eliminating device CD during transportation, the first conductive brush CD221 contacts the surface of the entire width of the liquid crystal panel 100. As shown in FIG. 3D, as the liquid crystal panel 100 is transported and passed through the static eliminating device, the first conductive brush CD221 comes into contact with the liquid crystal panel 100 from the longitudinal end of the liquid crystal panel 100 until it is separated from the longitudinal end of the liquid crystal panel 100. contact. Therefore, in liquid When the crystal panel 100 is passed through the static eliminator, the first conductive brush CD221 can be in contact with the entire surface of the liquid crystal panel 100, and static electricity existing on the surface of the liquid crystal panel 100 and the terminal regions in the two width directions passes through the first conductive brush CD221. The first conductive brush holder CD222, the first holding mechanism CD21, and the transport unit frame CD11 flow out and are removed.
較佳是，除電裝置CD具備一對第2除電單元CD30。如圖3A、3B、3C所示，一對第2除電單元CD30，係分別設於第1保持機構CD21，沿著液晶面板100的搬運方向延伸，除去液晶面板100的長度方向的2個端子區域中的靜電帶電。 Preferably, the static eliminating device CD includes a pair of second static eliminating units CD30. As shown in FIGS. 3A, 3B, and 3C, the pair of second static elimination units CD30 are provided in the first holding mechanism CD21, and extend in the conveyance direction of the liquid crystal panel 100, and the two terminal regions in the longitudinal direction of the liquid crystal panel 100 are removed. The electrostatic charge in the middle.
一對第2除電單元CD30的各者，由第2保持機構CD31及第2除電機構CD32所構成。 Each of the pair of second static elimination units CD30 is composed of a second holding mechanism CD31 and a second neutralization mechanism CD32.
第2保持機構CD31，為導電性良好的金屬托架，如圖3B所示，其一側藉由螺絲201等緊固機構而固定於第1保持機構CD21，朝液晶面板100的搬運方向延伸之另一側則藉由螺絲201等緊固機構與第2除電機構CD32連結。 The second holding mechanism CD31 is a metal bracket having good conductivity. As shown in FIG. 3B, one side of the metal holder is fixed to the first holding mechanism CD21 by a fastening mechanism such as a screw 201, and extends toward the conveyance direction of the liquid crystal panel 100. The other side is coupled to the second neutralization mechanism CD32 by a fastening mechanism such as a screw 201.
如同第1除電機構CD22，第2除電機構CD32，由第2導電刷CD321及第2導電刷托座CD322所構成。第2導電刷CD321，由導電率108~1012Ω/□之導電性纖維材料所成，藉由在第2導電刷托座CD322的上部以相同間隔排列之螺絲201等鎖固機構，而被夾持於由金屬所成之第2導電刷托座CD322。因此，第1導電刷CD221與第1導電刷托座CD222係電性連接。第2導電 刷CD321的長度，雖是依據實際情況來決定，但一般而言被設定在50~300mm左右，只要能與液晶面板100的長度方向的端子區域之間確保充分的接觸即可。 Like the first neutralization mechanism CD22, the second neutralization mechanism CD32 is composed of a second conductive brush CD321 and a second conductive brush holder CD322. The second conductive brush CD321 is made of a conductive fiber material having a conductivity of 10 8 to 10 12 Ω/□, and is locked by a screw 201 or the like which is arranged at the same interval on the upper portion of the second conductive brush holder CD322. It is clamped to the second conductive brush holder CD322 made of metal. Therefore, the first conductive brush CD221 is electrically connected to the first conductive brush holder CD222. The length of the second conductive brush CD321 is determined depending on the actual situation. However, it is generally set to about 50 to 300 mm as long as sufficient contact can be ensured with the terminal region in the longitudinal direction of the liquid crystal panel 100.
如圖3B所示，第2除電機構CD32，藉由螺絲201而固定於第2保持機構CD31。因此，第2導電刷CD321，透過第2導電刷托座CD322、第2保持機構CD32、第1保持機構CD21、搬運單元框架CD11而被接地。 As shown in FIG. 3B, the second neutralization mechanism CD32 is fixed to the second holding mechanism CD31 by a screw 201. Therefore, the second conductive brush CD321 is grounded through the second conductive brush holder CD322, the second holding mechanism CD32, the first holding mechanism CD21, and the transport unit frame CD11.
當液晶面板100通過除電裝置時，如圖3B、3C、3D所示，一對第2導電刷分別與液晶面板100的長度方向的2個端子區域接觸，液晶面板100的長度方向的2個端子區域中的靜電透過第2導電刷CD321、第2導電刷托座CD322、第2保持機構CD31、第1保持機構CD21、搬運單元框架CD11而流出，藉此被除去。由於第2導電刷CD321沿著液晶面板100的搬運方向設置，因此當液晶面板100通過除電裝置時，第2導電刷CD321能夠與液晶面板100的長度方向的2個端子區域確保充分的接觸面積及接觸時間，故能對搬運中的液晶面板100充分地進行除電。 When the liquid crystal panel 100 passes through the static eliminator, as shown in FIGS. 3B, 3C, and 3D, the pair of second conductive brushes are respectively in contact with the two terminal regions in the longitudinal direction of the liquid crystal panel 100, and the two longitudinal directions of the liquid crystal panel 100 are two. The static electricity in the terminal region passes through the second conductive brush CD 321 , the second conductive brush holder CD 322 , the second holding mechanism CD 31 , the first holding mechanism CD 21 , and the transport unit frame CD 11 , and is discharged. Since the second conductive brush CD 321 is disposed along the transport direction of the liquid crystal panel 100, when the liquid crystal panel 100 passes through the static eliminator, the second conductive brush CD 321 can secure a sufficient contact area with the two terminal regions in the longitudinal direction of the liquid crystal panel 100. Since the contact time is sufficient, the liquid crystal panel 100 being transported can be sufficiently neutralized.
更佳是，如圖5所示，第2除電單元CD30係設置成能夠沿著液晶面板100的寬度方向而調整對於第1除電單元CD20上的固定位置。例如，如圖3C所示，將第1保持機構CD21中用來固定第2保持機構CD31之螺絲孔202形成為長型狀，藉此便能設計成於液晶面板100 的寬度方向容易地調整第2保持機構CD31的固定位置。此外，例如亦可設計成在第1保持機構CD21以規定的間隔形成一列的螺絲孔202，而固定第2保持機構CD31之螺絲201與不同螺絲孔202螺合，藉此便能在液晶面板100的寬度方向調整第2保持機構CD31的固定位置。 More preferably, as shown in FIG. 5, the second static eliminating unit CD30 is provided so as to be able to adjust the fixed position on the first static eliminating unit CD20 along the width direction of the liquid crystal panel 100. For example, as shown in FIG. 3C, the screw hole 202 for fixing the second holding mechanism CD31 in the first holding mechanism CD21 is formed into a long shape, whereby the liquid crystal panel 100 can be designed. The fixed position of the second holding mechanism CD31 is easily adjusted in the width direction. Further, for example, it is also possible to design a screw hole 202 that is formed in a row at a predetermined interval in the first holding mechanism CD21, and the screw 201 that fixes the second holding mechanism CD31 is screwed with the different screw holes 202, whereby the liquid crystal panel 100 can be formed. The fixed position of the second holding mechanism CD31 is adjusted in the width direction.
按照上述構造，能夠因應尺寸相異之液晶面板而於液晶面板的寬度方向設置第2除電單元CD30的位置，能夠彈性地因應各種型號及尺寸的液晶面板的除電。 According to the above configuration, the position of the second static eliminating unit CD30 can be set in the width direction of the liquid crystal panel in accordance with the liquid crystal panel having different sizes, and the liquid-removal of the liquid crystal panel of various models and sizes can be flexibly responded to.
