Description
本發明係關於一種背光模組光學膜之自動組裝系統與方法。The invention relates to an automatic assembly system and method for an optical film of a backlight module.
由於液晶顯示器的重量輕、外形薄、驅動功率消耗低等原因，已經得到廣泛的應用。這種液晶顯示器被用作攜帶式電腦例如膝上型個人電腦、辦公自動化裝置、音頻/視訊裝置、室內/室外廣告顯示裝置等。透過控制被應用至液晶層之電場以調節來自背光模組之光線，佔據大多數液晶顯示裝置之傳輸型液晶顯示裝置由此顯示影像。Liquid crystal displays have been widely used due to their light weight, thin profile, and low driving power consumption. Such a liquid crystal display is used as a portable computer such as a laptop personal computer, an office automation device, an audio/video device, an indoor/outdoor advertising display device, and the like. By controlling the electric field applied to the liquid crystal layer to adjust the light from the backlight module, the transmission type liquid crystal display device occupying most of the liquid crystal display devices thereby displays an image.
背光模組主要被分類為直射型與側光型。在側光型背光模組的結構中，放置一光源以面對導光板的側面，複數個光學膜被放置於液晶顯示面板與導光板之間。在側光型背光模組中，此光源向導光板的一側發射光線，導光板轉換線光源或點光源為面光源。在直射型背光模組的結構中，複數個光源被放置於液晶顯示面板下方。這種背光模組包含複數個光學膜，從而增加被照射到液晶顯示面板的光線的面均勻度與亮度。光學膜包含稜鏡膜與擴散膜，稜鏡膜包含稜鏡圖案且改變光線以沿與液晶顯示面板完全垂直的方向傳輸，擴散膜則使用擴散珠擴散光線。Backlight modules are mainly classified into direct type and side light type. In the structure of the edge type backlight module, a light source is placed to face the side of the light guide plate, and a plurality of optical films are placed between the liquid crystal display panel and the light guide plate. In the edge-light type backlight module, the light source emits light on one side of the light guide plate, and the light guide plate converts the line light source or the point light source into a surface light source. In the structure of the direct type backlight module, a plurality of light sources are placed under the liquid crystal display panel. The backlight module includes a plurality of optical films to increase the uniformity and brightness of the light that is incident on the liquid crystal display panel. The optical film comprises a ruthenium film and a diffusion film, the ruthenium film contains a ruthenium pattern and the light is changed to be transmitted in a direction completely perpendicular to the liquid crystal display panel, and the diffusion film diffuses the light using the diffusion beads.
「第1圖」與「第2圖」所示係為直射型背光模組20的結構的例子。The "first figure" and the "second figure" show an example of the structure of the direct type backlight module 20.
請參考「第1圖」與「第2圖」，直射型背光模組20包含光源31、底殼32、擴散板33與複數個光學膜34。Referring to "1st drawing" and "2nd drawing", the direct type backlight module 20 includes a light source 31, a bottom case 32, a diffusing plate 33, and a plurality of optical films 34.
底殼32容納複數個光源31。反射膜附著於底殼32中與光源正對的表面上。擴散板33被放置於光源31上方，複數個光學膜34被堆疊於擴散板33上。液晶顯示面板10被排列於最上的光學膜34之上。The bottom case 32 houses a plurality of light sources 31. The reflective film is attached to the surface of the bottom case 32 that faces the light source. The diffusion plate 33 is placed above the light source 31, and a plurality of optical films 34 are stacked on the diffusion plate 33. The liquid crystal display panel 10 is arranged above the uppermost optical film 34.
「第3圖」與「第4圖」所示係為側光型背光模組40的結構的例子。The example of the structure of the edge type backlight module 40 is shown in FIG. 3 and FIG.
「第3圖」與「第4圖」中，側光型背光模組40包含光源41、導光板42以及複數個光學膜34。光源41正對導光板42的側面。反射膜被放置於導光板42的側面與底面之上。複數個光學膜34被放置於導光板42與液晶顯示面板10之間。In the "Fig. 3" and "Fig. 4", the edge type backlight module 40 includes a light source 41, a light guide plate 42, and a plurality of optical films 34. The light source 41 faces the side of the light guide plate 42. The reflective film is placed on the side and bottom surfaces of the light guide plate 42. A plurality of optical films 34 are placed between the light guide plate 42 and the liquid crystal display panel 10.
如果光學膜34未準確地組裝於背光模組20與40中，由於照射到液晶顯示面板10的光線的亮度與面均勻度的原因，所以準確地組裝光學膜34很重要。光源、光源線與底殼等被組裝，大量工人在導光板或擴散板上堆疊光學膜，從而組裝背光模組。If the optical film 34 is not accurately assembled in the backlight modules 20 and 40, it is important to accurately assemble the optical film 34 due to the brightness and surface uniformity of the light that is incident on the liquid crystal display panel 10. The light source, the light source line and the bottom case are assembled, and a large number of workers stack an optical film on the light guide plate or the diffusion plate to assemble the backlight module.
在習知技術中，光學膜的組裝大部分係透過工人人工完成。因為光學膜的人工組裝依賴工人的人工作業，所以難以減少製程時間，並且需要大量人員，例如***光學膜的人員、使用搬運車運輸光學膜的人員、堆疊光學膜的人員、檢查光學膜的人員等等，此外還需要相對較大的工作空間。另外，光學膜的人工組裝的問題在於在運輸或堆疊這些光學膜期間，光學膜被直接暴露給工人的手或者來自工人的外來物質，在組裝光學膜的過程中光學膜被外來物質污染，光學膜在堆疊時於其間滑動等。最輕微的滑動或磨擦會刮擦光學膜的表面，從而損傷光學膜的表面上形成的精細 圖案。In the prior art, the assembly of the optical film is mostly done manually by a worker. Since the manual assembly of the optical film relies on the manual work of the worker, it is difficult to reduce the process time, and a large number of people are required, such as a person who inserts the optical film, a person who transports the optical film using the truck, a person who stacks the optical film, and a person who inspects the optical film. Etc. In addition, a relatively large workspace is required. In addition, the problem of manual assembly of optical films is that during transport or stacking of these optical films, the optical film is directly exposed to a worker's hand or a foreign substance from a worker, and the optical film is contaminated with foreign matter during the assembly of the optical film, optical The film slides therebetween during stacking. The slightest sliding or rubbing scratches the surface of the optical film, thereby damaging the fineness formed on the surface of the optical film. pattern.

The two-axis transport robot in the second stacking module 62 moves the pad fixing frame 71 and the non-contact pads 72 in the z direction and transports them in the x-axis direction.
非接觸墊72可由眾所周知的非接觸墊實施。非接觸墊72可根據貝努里定理(Bernoulli’s Theorem)提升且浮動這些光學膜。例如，每一非接觸墊72包含進氣孔72a、中央部72b以及傾斜面72c，其中藉由進氣孔72a在固定壓力下供應乾淨的乾燥氣體(CDA)，中央部72b增加空氣壓力以產生一噴流，從而產生一提升壓力。非接觸墊72用以增加中央部72b側壁處移動空氣的速度以減少空氣壓力並且產生真空，從而向非接觸墊72吸引光學膜101至104。噴流從非接觸墊72的邊緣附近噴出，從而推出光學膜101至104。因此，光學膜101至104可提升且向非接觸墊72浮動，以無接觸的狀態被輸送。當非接觸式輸送機輸送光學膜101至104時，因為未與非接觸墊72接觸，所以光學膜101至104不會被刮擦或者損傷。The non-contact pads 72 can be implemented by well-known non-contact pads. The non-contact pads 72 can lift and float these optical films according to Bernoulli's Theorem. For example, each non-contact pad 72 includes an air intake hole 72a, a central portion 72b, and an inclined surface 72c, wherein a clean drying gas (CDA) is supplied at a fixed pressure by the air inlet hole 72a, and the central portion 72b increases the air pressure to generate A jet flows to create a lifting pressure. The non-contact pads 72 serve to increase the velocity of the moving air at the sidewalls of the central portion 72b to reduce air pressure and create a vacuum to attract the optical films 101 to 104 to the non-contact pads 72. The jet is ejected from the vicinity of the edge of the non-contact pad 72, thereby ejecting the optical films 101 to 104. Therefore, the optical films 101 to 104 can be lifted and floated toward the non-contact pad 72, and are conveyed in a contactless state. When the non-contact conveyor conveys the optical films 101 to 104, since the non-contact pads 72 are not in contact, the optical films 101 to 104 are not scratched or damaged.
非接觸式輸送機使得光學膜101至104在非接觸狀態中提升且浮動，從而在主輸送機裝置81中將它們輸送。透過阻擋空氣進入非接觸墊72，非接觸式輸送機在位於主輸送機裝置81上的其他光學膜101至104上堆疊光學膜101至104。主輸送機裝置81提供一對齊導引裝置82，這樣非接觸式輸送機或第一可延伸式輸送機裝置110轉遞的這些光學膜則自行對齊。對齊導引裝置82包含一彎曲面，相對主輸送機裝置81成預定角。The non-contact conveyor causes the optical films 101 to 104 to be lifted and floated in a non-contact state, thereby conveying them in the main conveyor device 81. The non-contact conveyor stacks the optical films 101 to 104 on the other optical films 101 to 104 located on the main conveyor device 81 by blocking air from entering the non-contact pads 72. The main conveyor unit 81 provides an alignment guide 82 such that the optical films conveyed by the non-contact conveyor or the first extendable conveyor unit 110 are self-aligned. The alignment guide 82 includes a curved face at a predetermined angle relative to the main conveyor device 81.
「第11圖」與「第12圖」所示係為使用第一可延伸式輸送機裝置110作為例子堆疊光學膜的作業的剖面圖。The "Fig. 11" and "Fig. 12" are sectional views showing the operation of stacking the optical film using the first extendable conveyor device 110 as an example.
請參考「第11圖」與「第12圖」，第一可延伸式輸送機裝置110包含驅動滾輪111、第一至第三閑置滾輪112至114以及滾帶115。Referring to "11th" and "12th", the first extendable conveyor device 110 includes a drive roller 111, first to third idle rollers 112 to 114, and a roller belt 115.
第一閑置滾輪112、驅動滾輪111以及第二閑置滾輪113排列為L形。滾帶115於第一閑置滾輪112與第二閑置滾輪113之間捲動。驅動滾輪111的直徑小於捲動滾帶115中相對表面之間的距離，並且被放置於L形的彎曲部。第三閑置滾輪114被放置於L形的另一彎曲部且與滾帶115接觸。The first idle roller 112, the drive roller 111, and the second idle roller 113 are arranged in an L shape. The roller belt 115 is rolled between the first idle roller 112 and the second idle roller 113. The diameter of the driving roller 111 is smaller than the distance between the opposing surfaces in the rolling belt 115, and is placed in the L-shaped bent portion. The third idle roller 114 is placed on the other curved portion of the L shape and is in contact with the roller belt 115.
第一閑置滾輪112的旋轉軸可旋轉地與x軸線性導桿(圖中未表示)耦合，從而沿x軸方向線性移動。當滾帶115連同驅動滾輪111的旋轉一起旋轉時，與滾帶115連結的第一閑置滾輪112在x軸方向線性被移動。第二閑置滾輪113的旋轉軸可旋轉地與z軸線性導桿(圖中未表示)耦合，從而沿z軸方向線性移動。The rotating shaft of the first idle roller 112 is rotatably coupled to an x-axis linear guide (not shown) to linearly move in the x-axis direction. When the roller belt 115 rotates together with the rotation of the drive roller 111, the first idle roller 112 coupled to the roller belt 115 is linearly moved in the x-axis direction. The rotating shaft of the second idle roller 113 is rotatably coupled to the z-axis linear guide (not shown) to linearly move in the z-axis direction.
驅動滾輪111被固定至固定區塊(圖中未表示)，並且受到固定位置的伺服馬達(圖中未表示)的驅動力而旋轉。驅動滾輪111令第一閑置滾輪112在x軸方向與第二閑置滾輪113在z軸方向前進或倒退。驅動滾輪111的旋轉方向可控制第一閑置滾輪112與第二閑置滾輪113的前進與倒退。位於滾帶115的L形狀的另一彎曲部的第三閑置滾輪114旋轉以導引滾帶115的旋轉。The drive roller 111 is fixed to a fixed block (not shown) and is rotated by a driving force of a servo motor (not shown) at a fixed position. The driving roller 111 causes the first idle roller 112 to advance or retreat in the z-axis direction with the second idle roller 113 in the x-axis direction. The direction of rotation of the driving roller 111 controls the advancement and retreat of the first idle roller 112 and the second idle roller 113. The third idle roller 114 located at the other curved portion of the L shape of the roller belt 115 rotates to guide the rotation of the roller belt 115.
如「第11圖」與「第13圖」所示，當非接觸式輸送機所傳送的光學膜101至104被接收時，第一可延伸式輸送機裝置110的驅動滾輪111順時針旋轉。因此，當滾帶115順時針方向旋轉時，第一閑置滾輪112沿x軸方向前進以接收光學膜101至104，同時第二閑置滾輪113上向移動第一閑置滾輪112的移動距離D。As shown in "Fig. 11" and "Fig. 13", when the optical films 101 to 104 conveyed by the non-contact conveyor are received, the driving roller 111 of the first extendable conveyor device 110 rotates clockwise. Therefore, when the roller belt 115 rotates in the clockwise direction, the first idle roller 112 advances in the x-axis direction to receive the optical films 101 to 104 while the second idle roller 113 moves the moving distance D of the first idle roller 112 upward.
如「第12圖」與「第14圖」所示，當光學膜101至104被放到主輸送機裝置81上時，第一可延伸式輸送機裝置110的驅動滾輪111反時針方向旋轉。此時，如「第15圖」所示，第一可延伸式輸送機裝置110的滾帶115沿光學膜101至104向下移動的方向(反時針方向)旋轉，因此滾帶115與光學膜101至104之間沒有滑移。因此，當滾帶115反時針方向旋轉時，第一閑置滾輪112在主傳送器裝置81上放下光學膜101至104，且與光學膜101至104未發生滑移，如「第15圖」所示，同時第二滾輪113向下移動第一閑置滾輪112的移動距離D。As shown in "Fig. 12" and "Fig. 14", when the optical films 101 to 104 are placed on the main conveyor device 81, the driving roller 111 of the first extendable conveyor device 110 rotates counterclockwise. At this time, as shown in FIG. 15, the roller belt 115 of the first extendable conveyor device 110 rotates in the direction in which the optical films 101 to 104 move downward (counterclockwise direction), and thus the roller belt 115 and the optical film There is no slip between 101 and 104. Therefore, when the roller belt 115 rotates counterclockwise, the first idle roller 112 lowers the optical films 101 to 104 on the main conveyor device 81, and does not slip with the optical films 101 to 104, as shown in Fig. 15. It is shown that the second roller 113 moves the moving distance D of the first idle roller 112 downward.
第一閑置滾輪112前進與倒退時，第一閑置滾輪112的移動距離D與移動速度V與第二閑置滾輪113的D’與V’相同。When the first idle roller 112 advances and retreats, the moving distance D and the moving speed V of the first idle roller 112 are the same as D' and V' of the second idle roller 113.
上述實施例中各裝置的作業時序可藉由控制程式例如程式邏輯控制(program logic control；PLC)被控制。The operation timing of each device in the above embodiment can be controlled by a control program such as program logic control (PLC).
如上所述，依照實施例，放置自動設備例如於無塵室中安裝的主輸送機裝置、非接觸式輸送機以及可延伸式輸送機，以及使用這些自動設備堆疊光學膜。因此，可最小化光學膜組裝製程的人工作業並且可減少製程時間。此外，依照實施例，透過使用非接觸式輸送機與可延伸式輸送機，可避免光學膜的輸送與堆疊程序中由於外來物質、滑移、刮擦等原因導致的污染，從而最小化光學膜之劣質組裝。As described above, according to the embodiment, the automatic conveyor such as the main conveyor device, the non-contact conveyor, and the extendable conveyor installed in the clean room are placed, and the optical film is stacked using these automatic devices. Therefore, the manual work of the optical film assembly process can be minimized and the process time can be reduced. In addition, according to the embodiment, by using a non-contact conveyor and an extendable conveyor, contamination of the optical film during transport and stacking due to foreign matter, slippage, scratching, and the like can be avoided, thereby minimizing the optical film. Inferior assembly.
