(5) (5)200406280 ，進行單體表面的淸潔作業。 如第6圖所示，在傳統的淸潔方法中，爲了縮短淸潔 時間及達成裝置的小型化，是令接觸滾子3 1的按壓力直 接作用於單體70的表面上地，使頭部或面板移動手段在 前後左右的方向移動，並在接處滾子3 1位於單體7 0表面 上的狀態下（係指頭部旋轉軸位於單體7 0的表面上）， 開始進行淸潔（硏磨帶開始旋轉，頭部或面板移動手段開 始在前後左右的方向上移動）。然後在淸潔的過程中，頭 部是根據虛線3 5 '所示的軌道在單體7 〇的表面上蛇行， 進而使頭部或面板支承手段在前後左右的方向移動，而頭 部蛇行移動的折返，是在頭部旋轉軸34位於單體70表面 的狀態下進行。 [專利文獻1]日本特開平11-19859號公報（0002、 0010、0011 段落及第 1、2、4、5 圖）。 [專利文獻2 ]日本特開2 0 0 1 - 1 9 8 7 5 3號公報（ 0017〜0020段落及第2圖）。 【發明內容】 [發明欲解決之課題] 然而’在上述的傳統淸潔方法中，由於開始淸潔時接 觸端子的按壓力直接作用於單體的表面上，且在單體的表 面上執行頭部蛇行移動的折返，故產生以下的問題。 第1，被封入單體之面板間的間隔材（第5 ( a )、( b )圖中以圖號7 4表示），將被淸潔時作用於單體表面之 一 11 一 (6) (6)200406280 接觸滾子的初期按壓力所壓潰而產生變形，因此，導致使 用液晶顯示裝置時，其晝面產生局部變黑，形成所謂無法 淸楚地顯示圖像的問題。此外，當淸潔開始時、或折返頭 部的蛇行移動之際，將於該面板表面上的特定範圍造成所 謂局部性硏磨帶之皺紋或傷痕的問題。 第2，當開始淸潔初期之接觸滾子的按壓力直接作用 於單體表面上時，單體導軌與單體之間將產生段差，以致 當旋轉中的接觸滾子通過單體導軌的表面之際，由接觸滾 子所運送的硏磨帶鉤掛於單體導軌與單體之間的段差，進 而造成所謂硏磨帶破損的問題。除此之外，在前述的狀態 下，有時也會造成接觸滾子的磨損。 第3，由於在單體導軌與單體之間設有間隙（約2的 間隙）（在第5圖中爲圖號22 )，當折返頭部的蛇行移 動之際’單體將隨著頭部形成輕微振動，使單體的邊緣衝 撞單體導軌，導致產生所謂單體邊緣損傷的問題。 第4，當淸潔TFT液晶單體側的單體表面時，於淸潔 開始、或折返頭部的蛇行移動之際，把單體的傳遞形成領 域按壓於單體導軌，將產生所謂傳遞形成領域損傷的問題 〇 本發明是有鑑於上述問題所硏發的發明，因此，本發 明的目的是在使用旋轉式面板淸潔裝置，對於兩張面板間 封入液晶與間隔材的單體進行淸潔的方法中，提供一種： 不會使封入單體面板間的間隔材變形；當淸潔開始時、或 折返頭部的蛇行移動之際，不會在面板表面上的特定範圍 一 12 - (7) (7)200406280 造成局部性硏磨帶之皺紋或傷痕；不會導致硏磨帶及接觸 滾子受損；不會損傷單體的邊緣；不會損傷傳遞形成領域 :可以淸潔單體全體表面的方法。 [用以解決課題之手段] 本發明爲使用旋轉式面板淸潔裝置，對單體表面進行 淸潔的方法。 本發明所採用的旋轉式面板淸潔裝置是由：用來支承 面板的手段（面板支承手段）；和於下端配置接觸滾子， 並具有透過該接觸滾子來運送硏磨帶之手段（帶供給手段 )的頭部；和通過接觸滾子的中央沿著垂直於面板表面之 軸線產生旋轉的手段（頭部旋轉手段）；和使頭部或面板 支承手段在上下方向上移動的手段（Z移動手段）；及使 頭部或面板支承手段在前後左右的方向上移動的手段（ XY移動手段）所構成。 本發明的方法，首先是將面板支承於上述旋轉式面板 淸潔裝置的面板支承手段上。 該面板支承手段，具有一個包含與面板平面形狀大致 相同之開口的單體導軌。該單體導軌是用來保護面板的外 緣部。一旦將面板放置於單體導軌的開口內，該面板的表 面係與單體導軌的表面位於大略相同的平面上。 面板最好是藉由面板內已知的吸附裝置形成吸附後， 固定於面板支承手段上的預定位置。然後，藉由將該面板 配置於單體導軌之開口內的方式來配置單替導軌，藉此可 一 13 - (8) (8)200406280 使面板被支承於面板支承手段上。 而單體導軌，可採用一張厚度略等於面板厚度且表面 平坦的板子，在中央形成一個略等於面板平面形狀的開口 來作爲單體導軌，或者在四角形的面板週邊配置四張板子 作爲單體導軌亦無妨。 接下來，利用使頭部旋轉軸位於單體導軌表面上的方 式’決定頭部或面板支承手段的位置，使頭部或面板支承 手段朝上下移動，並透過接觸滾子將硏磨帶按壓於單體導 軌的表面。 然後，一邊透過接觸滾子運送硏磨帶，一邊使頭部在 頭部旋轉軸上旋轉，並使頭部在面板的表面上形成蛇行移 動地，令頭部或面板支承手段在前後左右的方向移動。而 頭部蛇行移動的折返，是在頭部旋轉軸位於單體導軌表面 的狀態下進行。 換言之，爲了解決上述的問題，本發明是在頭部旋轉 軸位於單體導軌表面的狀態下開始面板的淸潔作業。此外 ，淸潔過程中之頭部蛇行移動的折返，是在頭部旋轉軸位 於單體導軌表面的狀態下開始執行。 這樣一來，面板的全體表面便能獲得淸潔。 【實施方式】 本發明的方法，是對將液晶與間隔材封入如將第5圖 所示之兩張面板7 1、7 2而成的單體之類的表面進行淸潔 的方法。本發明的面板淸潔方法，是採用如第2〜4圖中已 一 14 一 200406280 Ο) 知的旋轉式面板淸潔裝置進行。 <旋轉式面板淸潔裝置> 如第2〜4圖所示地，旋轉式面板淸潔裝置1 〇是由·· 用來支承面板7 0的面板支承手段2 0 ;和於下端配置略呈 圓筒形的接觸滾子3 1，並具有透過該接觸滾子3 1來運送 硏磨帶T之帶供給手段的頭部3 0 ·，和使頭部3 0通過接觸 浪子3 1中央之軸線（第1圖中以圖號3 4表示，稱爲頭部 旋轉軸）產生旋轉的頭部旋轉手段；和使頭部3 〇在上下 方向（箭號Z指示的方向）上移動的Z移動手段；及使 頭部30在前後左右的方向（箭號X、γ指示的方向）上 移動的XY移動手段所構成（請參考譬如日本特開平11-1 9 8 5 9號公報）。雖然在圖式的範例中，頭部3 0是在上 下級前後左右的方向上移動，但是亦可固定頭部3 0的位 置’使面板支承手段2 0在上下級前後左右的方向上移動 <面板支承手段> 如第1〜4圖所示，面板支承手段2 0，是由用來吸附 面板7〇背面的吸附裝置（圖面中未顯示）、及具有一個 略等於面板平面形狀之開口的單體導軌2 1所構成。面板 7 0係藉由以吸附裝置吸附該面板背面的方式，固定於面 板支承手段20的預定位置。藉由將單體70配置於單體導 軌2 1之開口內的方式來配置單替導軌2 1。藉此，可使單 -15- 200406280 do) 體7〇被支承於單體支承手段上。面板70的外緣部，係由 導軌2 1所保護，如第5圖（a ) 、（ b )所示地，在面板 70與單體導軌21之間設有間隙22。而放置於單體導軌 2 1開口內之面板7 〇的表面，係與單體導軌2 1的表面位 於大略相同的平面上。 雖然圖面中並未顯示，但亦可採用配置於面板7 0四 週的4張板子作爲單體導軌2 1，其作法是利用上述的吸 附裝置來吸附由具有通氣性的皮帶式輸送機移送至面板支 承手段20上特定位置之面板70的背面，再以前述4張板 子採包圍吸附於特定位置的面板70之前後左右的方式， 包夾於面板70的四周，藉此使面板70支承於面板支承手 段20 (請參考日本特開200卜1 9 8 7 5 3號公報）。 <頭部> 頭部3 0具有硏磨帶供給手段。該硏磨帶供給手段是 由：可自由拆卸地安裝纒繞著硏磨帶T之硏磨帶滾子的滾 子安裝部3 2 ;及可自由拆卸地安裝有捲取滾子安裝部3 2 的硏磨帶滾子所送出之硏磨帶T用捲取滾子的帶捲取部 3 3。頭部3 0更於下端配置接觸滾子3 1，並透過該接觸滾 子3 1將滾子安裝部3 2之硏磨帶滾子所送處的硏磨帶τ , 按壓於由面板支承手段所支承之面板7 〇的表面。 <頭部旋轉手段> 頭部3 0是連接在安裝於後述Z移動手段的Z移動台 -16 (11) (11)200406280 4 〇之心軸4 3的正下方。心軸4 3則是透過皮帶與安裝於z 移動台4〇的馬達44形成連結，並藉由馬達的驅動使 心軸4 3產生旋轉，藉此，可使頭部3 〇沿著通過接觸滾子 中央的軸線（第1圖所示的頭部旋轉軸3 4 )產生旋轉。 在此，Z移動台4〇的上方式形成開放，並經由心軸中 空的旋轉軸（圖面中未顯示）由該Z移動台4 0的上方， 將電力供應至使頭部3 〇中帶捲取部3 3之捲取滾子產生旋 轉的馬達（圖面中未顯示）。 < Z移動手段> z移動台40是透過軌道41可上下移動地安裝於貫穿 上下方向（箭號Z的方向）之X移動台5〇的中空內部。 在由X移動台後方突出的棚架上，固定著連接於外 部供氣手段（圖面中未顯示）的活塞氣壓缸4 2，該活塞 氣壓缸4 2是經由設置於χ移動台5 〇後方之上下長形細 縫5 1 ’連結於配置在X移動台5 〇中空內部的Ζ移動台 4〇，藉由驅動活塞氣壓缸42，可使ζ移動台4〇在上下方 向（箭號Ζ的方向）上移動。 < ΧΥ移動手段> X移動台50是可自由左右（箭號χ的方向）移動地 配置在具有左右長形開口 61之γ移動台6〇的開口 61內 。該Υ移動台6〇上安裝有於開口 6】前後側分別朝左右 延伸的導軌62，而ζ移動台是透過該導軌安裝於 一17 -

[Prior art] Liquid crystal display devices used in precision electronic equipment such as computers, televisions, mobile phones, computers, watches, etc. Generally, after the TFT liquid crystal monomer and the color filter are bonded, the liquid crystal is sealed in the panel to make a single A polarizing plate is bonded to both sides of the monomer to make a liquid crystal monomer. Next, a TCP (Tape Carrier Package) and a printed circuit board are mounted around the liquid crystal cell ', and a backlight as a light source is mounted on the TFT liquid crystal cell side rear assembly frame. TFT liquid crystal monomers are formed by retaining L-shaped regions for transmission along two sides of a glass substrate, forming electrodes and transistors on the glass substrate, and subsequently forming an alignment film on the surface and honing the surface of the alignment film. Panel. In addition, the color filter is a panel formed by coating a pigment photoresist on a glass substrate, and repeating exposure, development, and removal of resistance to form 3 colors, and then forming an alignment film thereon and honing the surface of the alignment film. . The laminating action of these panels can be implemented in the following ways. First, one '~ 1 one (2) (2) 200406280 is used around the alignment film of the TFT liquid crystal monomer, and the coating height is about 3 0 // with a meter. After the thermosetting sealing material of m is formed, it is formed by being transmitted in an L-shaped region on a glass substrate. Next, evenly distribute the spacers in the area of the alignment film surrounded by the sealing material, so that a space of about 5 // m is formed between the alignment films of the above panel, and then attach the color filter to the previously coated TFT. The liquid crystal monomer is only oriented on the sealing material around the film. Apply a sealant as much as possible on the periphery of the alignment film of the TFT liquid crystal cell at a gap of 10 to 20 width on one side of the glass substrate other than the L-shaped region. The liquid crystal passes through this gap (also called sealing). The entrance) is sealed between the panels laminated in the above manner. After the liquid crystal is sealed between the panels, an ultraviolet curing resin is applied to the sealing opening, and the sealing opening is sealed by ultraviolet curing. After the monomer is produced in the above manner, and both sides of the monomer are cleaned, the polarizing plate is adhered to both sides of the monomer to complete the production of the liquid crystal monomer. Then, after the above-mentioned steps of TCP installation, circuit board installation, and backlight installation are completed, the production of the liquid crystal display device is completed. Although the liquid crystal display device is manufactured in the above manner, once the polarizing plate is attached to the surface of the monomer in the state where foreign matter is attached to the surface of the monomer, the light will be polarized due to being blocked by the foreign material, which will cause the so-called "dust "NG" display quality issues. Moreover, once the dust NG is found, it is necessary to restart the cleaning of the surface of the single body and the adhesion of the polarizing plate. This repeated operation is quite tedious and time-consuming. Therefore, the cleaning operation on both sides of the single body before laminating the polarizing plate is an extremely important step in the manufacturing process of the liquid crystal display device. (3) (3) 200406280 The cleaning operation on both sides of the single body adopts a conventional rotary panel cleaning device commonly used for panels formed of glass, plastic, etc. (for example, Patent Document 1), and Proceed in a 1-sided manner. The rotary panel cleaning device is composed of: a panel supporting means for supporting the panel; and a head provided with a slightly cylindrical contact roller at the lower end and having a conveying means for conveying the honing belt by the contact roller ; And means for rotating the center of the contact roller along an axis perpendicular to the surface of the panel; and means for moving the head or panel support means in the up-down direction; and means for moving the head or panel support means in the front-rear direction It is constituted by means of upward movement (refer to the device described in Patent Document 1). For the cleaning method using the panel of the rotary panel cleaning device (represented by a single body), first, the monomer must be supported by the panel supporting means of the rotary surface cleaning device. As shown in Fig. 6, the panel supporting means 20 has a single-unit guide 21 including an opening having substantially the same shape as that of the single-unit 70. The single-piece guide 21 is used to protect the outer edge of the single-piece 70 (especially, as shown in Figs. 5 (a) and (b), the L-shape for transmission formation on the TFT liquid-crystal single-piece 71 side Type area 7 1 ′), and the surface of the single unit 70 placed in the opening of the single unit guide 21 is located on the substantially same plane as the surface of the single unit guide 21. The monomer 70 is used to adsorb the back surface of the monomer 70 by a known means such as an adsorption device and fix it to a predetermined position on the panel supporting means 20 *. In addition, by arranging the single unit 70 in the opening of the single unit guide 2 1, the single unit guide 2 1 ′ can be arranged so that the single unit 70 is supported on the single unit support 9 9 (4) (4) 200 406 280 Support method. FIG. 5 is a partial cross-sectional view showing the unit 70 and the unit guide 21 when the unit 70 is supported on the unit guide 21. Fig. 5 (a) is a partial cross-section view of the unit 7 when the color filter 72 is positioned above and the unit guide 2] [The section 5 (b) is a diagram when the TFT liquid crystal unit 71 is positioned above Partial sectional view of the unit 70 and the unit guide 21. As shown in the figure, the cell 70 is a liquid crystal and a spacer 74 sealed between the TFT liquid crystal cell 71 and the color filter 72, and the liquid crystal and the spacer 74 are sealed by a sealing material 73. The transfer formation area 7 Γ is formed in a portion protruding from the TFT liquid crystal cell 71 'as shown in the figure, and is protected by a stepped portion of the cell guide 21' and is formed between the cell 70 and the cell guide 21 A gap 22 is provided therebetween to avoid friction with the unit guide rail 21 due to the micro movement of the unit 70 caused by the vibration of the device during the cleaning process. It is also possible to use a board forming an opening approximately equal to the flat shape of the unit 70 as the unit guide rail 21 (refer to FIG. 6), or arrange four boards around the unit unit 70 (not shown) It does not matter as a single guide rail 2 1. (For example, Patent Document 2). Next, the head or the panel supporting means is moved up and down, and the honing belt is pressed against the single surface supported by the panel supporting means by the contact roller. Then, while the honing belt is conveyed through the contact roller, the head is moved. The part rotates on an axis passing through the center of the contact roller (hereinafter referred to as the head rotation axis), and the contact roller is used to press the honing belt against the surface of the monomer, so that the head or the panel support means is in the front, rear, left, and right directions. Move, in this way a 10-(5) (5) 200406280, to clean the surface of the monomer. As shown in FIG. 6, in the conventional cleaning method, in order to shorten the cleaning time and achieve miniaturization of the device, the pressing force of the contact roller 31 is directly applied to the surface of the monomer 70 to make the head The part or panel moving means moves in the front-back, left-right, and left-right directions, and starts when the roller 31 is on the surface of the unit 70 (the rotation axis of the head is on the surface of the unit 70). Jie (the honing belt starts to rotate, and the head or panel moving means starts to move in the front, back, left, and right directions). Then, in the process of cleaning, the head snakes on the surface of the unit 70 according to the track shown by the dotted line 3 5 ′, so that the head or the panel support means moves in the forward, backward, leftward, and rightward direction, and the head snakes. The return is performed in a state where the head rotation shaft 34 is located on the surface of the single body 70.

[Summary of the Invention] [Problems to be Solved by the Invention] However, in the above-mentioned conventional cleaning method, since the pressing force of the contact terminal at the beginning of cleaning is directly applied to the surface of the cell, and the head is executed on the surface of the cell. Since the back and forth movement of the part zigzags, the following problems arise. First, the spacer between the panels enclosed in the monomer (shown in Figure 5 (a), (b) as Figure No. 7 4), will act on one of the surfaces of the monomer when being cleaned 11-(6) (6) 200406280 The initial contact pressure of the roller is crushed and deformed. Therefore, when the liquid crystal display device is used, the daytime surface of the liquid crystal display device becomes partially black, causing a problem that the image cannot be displayed clearly. In addition, the problem of wrinkles or scars on the so-called local honing belt will be caused in a specific area on the surface of the panel when scouring is started or when the meandering movement of the head is turned back. Second, when the pressing force of the contact roller at the beginning of cleaning is directly applied to the surface of the monomer, a step will be created between the monomer guide and the monomer, so that when the contact roller in rotation passes through the surface of the monomer guide At this time, the honing belt conveyed by the contact roller is caught on the step between the single guide rail and the single body, which causes a problem that the so-called honing belt is broken. In addition, under the aforementioned conditions, wear of the contact roller may occur. Third, because a gap (a gap of about 2) is provided between the monorail and the monolith (in Fig. 5, it is Figure No. 22). When the serpentine moves back to the head, the monolith will follow the head. The part vibrates slightly, causing the edge of the cell to hit the rail of the cell, leading to the problem of so-called cell edge damage. Fourth, when the cell surface on the cell side of the TFT liquid crystal is cleaned, the cell transfer formation area is pressed against the cell guide at the beginning of the cleaning or the meandering movement of the head. The so-called transfer formation occurs. The problem of damage in the field. The present invention is an invention that was developed in view of the above problems. Therefore, the object of the present invention is to clean a monomer in which a liquid crystal and a spacer are sealed between two panels using a rotary panel cleaning device. In the method, a method is provided: the spacers enclosed between the individual panels will not be deformed; when the cleaning is started, or when the head is snaked back and forth, it will not be in a specific range on the surface of the panel-12-(7 ) (7) 200406280 Causes wrinkles or scars on the local honing belt; does not cause damage to the honing belt and contact roller; does not damage the edge of the monomer; does not damage the transmission area: can clean the entire monomer Surface approach. [Means for solving the problem] The present invention is a method for cleaning the surface of a single body using a rotary panel cleaning device. The rotary panel cleaning device used in the present invention comprises: means for supporting the panel (panel supporting means); and a contact roller disposed at the lower end, and means for conveying the honing belt through the contact roller (belt (Supply means) head; and means for rotating the head or panel support means in the up-and-down direction by contacting the center of the roller along an axis perpendicular to the surface of the panel (head rotation means) (Z Moving means); and means for moving the head or panel supporting means in the forward, backward, leftward, and rightward direction (XY moving means). In the method of the present invention, first, the panel is supported on the panel supporting means of the rotary panel cleaning device. The panel supporting means has a single guide rail including an opening substantially the same as the planar shape of the panel. The single rail is used to protect the outer edge of the panel. Once the panel is placed in the opening of the monorail, the surface of the panel is located on approximately the same plane as the surface of the monorail. The panel is preferably fixed to a predetermined position on the panel supporting means after being adsorbed by a known adsorption device in the panel. Then, the single replacement rail is arranged by arranging the panel in the opening of the single rail, so that the panel can be supported on the panel supporting means by 13-(8) (8) 200406280. For a single guide rail, a single plate with a thickness slightly equal to the thickness of the panel and a flat surface can be formed in the center as a single guide rail, or four plates can be arranged around the quadrilateral panel as a single unit. The rails are fine. Next, the position of the head or panel support means is determined by positioning the head rotation axis on the surface of the single guide rail. The head or panel support means is moved up and down, and the honing belt is pressed against the roller by the contact roller. The surface of the monorail. Then, while conveying the honing belt through the contact roller, the head is rotated on the rotation axis of the head, and the head forms a meandering movement on the surface of the panel, so that the head or the panel support means is in the front, back, left, and right directions. mobile. The meandering movement of the head is performed while the head rotation axis is located on the surface of the single guide rail. In other words, in order to solve the above-mentioned problem, the present invention starts the cleaning operation of the panel in a state where the head rotation shaft is located on the surface of the single guide rail. In addition, the retracement of the head's meandering movement during the cleaning process is performed when the head's rotation axis is located on the surface of the single guide rail. In this way, the entire surface of the panel can be cleaned.
