Field of the Invention The present invention relates to a glass substrate transfer apparatus, and more particularly to a glass substrate transportation apparatus for use in a wet environment. [Prior Art] With advances in optical technology and semiconductor technology, liquid crystal display devices (LCDs) have been widely used in electronic product display devices. LCD monitors have high image quality, small size, light weight, low voltage drive, low power consumption and wide application range. They have been widely used in portable TVs, mobile phones, video recorders, and notebook computers. In consumer electronics or computer products such as desktop monitors and projection TVs, it has become the mainstream of displays. Generally, the main body of the liquid crystal display is a liquid crystal cell, which is mainly composed of two glass substrates and a liquid crystal sealed between the substrates. At present, the liquid crystal display is mainly based on a thin film transistor (TFT) liquid crystal display, the upper and lower glass substrates of the liquid crystal are mainly used for sandwiching the liquid crystal, the lower substrate has a thin film transistor, and the upper substrate is a color. Filter (Color fther). The color filter forms a color filter layer of two primary colors of red (R), green (G), and blue (B) on the upper substrate, so that the liquid crystal display exhibits a rich color image. In the production process of liquid crystal displays, it is often necessary to transport the glass substrates in various processes. The conventional glass substrate conveying apparatus is composed of a lower bearing seat, a lower roller set, an upper bearing seat and an upper roller set. The lower roller set is pivotally connected to the lower bearing housing, and has a lower shaft and a lower roller shaft and a lower roller 296835 lower gear. The upper bearing seat is located on the lower bearing housing. The upper roller set is pivotally connected to the upper bearing housing, and has an upper rotating shaft and a roller piece and an upper gear which are disposed on the upper rotating shaft. Wherein, the gear train on the upper roller group meshes with the gear wheel under the lower roller group, so that the upper roller group rotates by the lower roller group. Thus, the user only needs to place the glass substrate between the upper roller and the lower roller in the rolling direction, and the glass substrate can be advanced by the driving of the upper and lower roller blades.
然而，使用上所述之玻璃基板輸送設備，會有下列缺 點： N (1) 上滾輪組之上齒輪容易因下滾輪組之下齒輪的推 斥而輕起，使得上滾輪組之上滚輪片肖下滾輪組之下滾輪 片之間的距離變大，造成上、下滾輪片與玻璃基板間的^ 擦力下降，因而產生傳送異常；以及 (2) 上滾輪組之上滾輪片與下滾輪組之下滾輪片之間 的距離因磨耗而增加，使得玻璃基板與上、下滾輪片之門 的摩擦力減少，造成玻璃基板前進不順。 特別是在玻璃基板的清潔製程中，由於製程環境非常 地潮濕且易滑，因此上滾輪片所提供的摩擦力往往不足: 再加上清潔製程常會施加特定的化學藥劑保養清洗，此將 使得原本就已經很濕滑的製程環境將更加地惡劣，這此: 素再再都使得傳送異常頻頻地發生。 沒一口 【發明内容】 此本發明—方面就是錢供—種_騎 其可增加上、下滾輪組與玻璃基板間的摩擦‘& 減少傳送異常的發生。 ’、’進而 1296835

之外側，而槽孔亦可具有槽孔螺紋，用以配合套筒螺紋。 這樣，使用者即可將定位件輕易地旋入槽孔中，並依旋入 槽孔的殊度，來計算施加給上滾輪組的下壓力。 續以上所述，定位件另可包含限位件，設置於套筒背 對上滾輪組的一端，當套筒螺紋完全旋入槽孔螺紋時，限 位件恰抵住頂壁。換言之，限位件係限制了定位件旋入槽 孔的距離，此將確保當限位件抵住頂壁時，上滾輪組所承 受的下壓力為一定值，其可讓使用者無須費心計算旋入槽 孔的距離。 1296835 ^另外，上述之上滾輪組可具有一抵接平面，而定位件 係抵住此抵接平面。也就是說，定位件與上滾輪組間的接 觸屬於平面接觸，其可確保上滾輪組承受穩定的下壓力， 避免因疋位件與上滾輪組間發生滑位而導致下壓力大俨 化。 田 本發明另一方面就是在提供一種玻璃基板之輸送設 備，其提供一對連續式的定位架及複數個定位件於滾輪輸 迗組的兩端，用以減少因濕滑及摩擦力不均所產生的 異常及破損。 ' ^根據本發明另一較佳實施例，一種玻璃基板之輸送設 備係由複數個滾輪輸送組、一對定位架及複數個定位件所 組成。其中’上述之複數個滾輪輸送組係彼此間隔一距離 设置，且每-滾輪輸送組均具有一對下輛承座、兩端分別 槐接此對下軸承座之下滾輪組、分別設置於此對下軸承座 上之-對上軸承座，以及兩端分別樞接於此對上轴承座並

140、上滾輪組150、定位架16〇及定位件2〇〇所組成。其 中，下滾輪組130係樞接於下軸承座12〇。上軸承座14〇 係設置於下軸承座120上。上滾輪組15〇係樞接於上軸承 座140,並嚙合下滾輪組13〇。定位架16〇係設置於上軸承 座14〇上，並具有槽孔162設置於定位架160之頂壁163 上。定位件200則設置於槽孔162，並抵住上滾輪組15〇, 使上滾輪組150承受下壓力，進而提升上滾輪組15〇、下滾 輪組130與玻璃基板之間的摩擦力。 ’…、第1B及ic圖’其分別緣示第ία圖中之定位件 =〇於安裝前後的剖面圖。由第1B及1C圖可知，上述之 定位件200係由套筒210、彈簧220及活塞230所組成。其 Ϊ296835 中，套筒210具有活塞孔212設置套筒210之第一端214。 彈簧220設置於套筒210内。活塞230則部分設置於套筒 210内，且活塞230之第一端234係抵住彈簧220，而活塞 230之第二端232則穿過活塞孔212並抵住'上滾輪組（第1A 圖所繪示之上滾輪組150)。進一步地比較第1B及1C圖可 知，彈簧220於定位件200安裝前後僅產生壓縮變形，而 無其他方向的變形（如：挫屈或彎曲），此係由於套筒21〇 拘束著彈簧220的行程，故彈簧220僅能在其軸向產生變 形，此將使得定位件200所提供的下壓力較為穩定，不致 因彈簧220挫屈而使下壓力大幅變化。此外，由於彈箬僅 在其軸向產生變形，故依照虎克定律，上滾輪組所承受的 下壓力與彈簧變形將是線性關係，因此上滾輪組所承受的 下壓力可輕易藉由彈簧變形來推知，而不需要複雜的計算。 再次參照第1A及1C圖，在本實施例中，定位件2〇〇 更可具有套筒螺紋240，設置於套筒21〇之外側，而槽孔 162亦可具有槽孔螺紋164,用以配合套筒螺紋24〇。這樣， 使用者即可將定位件200輕易地旋入槽孔162中，並依旋 入槽孔162的深度，來計算施加給上滾輪組15〇的下壓力。 續以上所述，疋位件200另可包含限位件250，設置於 套筒210背對上滾輪組150的第二端216，當套筒螺紋24〇 完全旋入槽孔螺紋164時，限位件25〇將恰抵住頂壁163。 換言之，限位件250係限制了定位件2〇〇旋入槽孔162的 距離，此將確保當限位件250抵住頂壁163時， 150所承受的下壓力為—定值，其可讓使用者無須費心言;算 旋入槽孔162的距離。 12 1296835 參照第ID圖，其繪示第1A圖之定位件200抵住上滾 輪組150部分的剖面圖。更具體地說，第1D圖係繪示第 1Α圖之上滾輪組150拆除齒輪151後的示意圖。在第1D 圖中，上述之上滾輪組可具有一抵接平面152，而定位件 200係抵住此抵接平面152。具體而言，上滾輪組可具有一 矩形塊153穿設於齒輪的内側，而定位件200係抵住此矩 形塊153上的抵接平面152。也就是說，定位件200與上滾 輪組間的接觸屬於平面接觸，其可確保上滾輪組承受穩定 的下壓力，避免因定位件200與上滾輪組間發生滑位而導 致下壓力大幅變化。 參照第2Α及2Β圖，其繪示依照本發明另一較佳實施 例玻璃基板之輸送設備的部分側視及正視圖。在第2Α及 2Β圖中，一種玻璃基板之輸送設備係由複數個滾輪輸送組 310、一對定位架360及複數個定位件400所組成。其中， 上述之複數個滾輪輸送組310係彼此間隔一距離設置，且 每一滾輪輸送組310均具有一對下軸承座320、兩端分別樞 接此對下軸承座320之下滾輪組330、分別設置於此對下軸 承座320上之一對上軸承座340,以及兩端分別樞接於此對 上轴承座340並喃合下滾輪組330之上滾輪組350。上述之 兩定位架360分別位於滾輪輸送組310的兩端，並設置於 每一滾輪輸送組310之上軸承座340上。此外，每一定位 架360均具有複數個槽孔362設置於其頂壁363上。而上 述之複數個定位件400則分別設置於這些槽孔362中，並 抵住每一滾輪輸送組310之上滾輪組350的兩端，使其承 受一下壓力，進而提升上滾輪組350、下滾輪組330與玻璃 13 1296835 基板之間的摩擦力。值得注意得是，抵住每—上滾輪組 兩端之定位件400將提供相同的下壓力，以避免玻璃 因兩端受力不等而產生旋轉’進而造成玻璃基板的破才)。 在本實施例中，每一定位件4〇〇的細部結構均與前述 相同，在此不再贅述。惟在本實施例中，每一定位件之套 同的長度均相等，因此當限位件4〇2抵住頂壁363時，每 一疋位件400提供給上滾輪組的下壓力均為一定值，其可 避免玻璃基板因受力不均而破損。 另外，每一滾輪輸送組310之上滾輪組3·5〇兩端均可 具有一抵接平面352,而定位件4〇〇係抵住此抵接平面 352。換言之，定位件4〇〇與上滾輪組35〇間的接觸係屬於 平面接觸，其可確保上滾輪組35〇承受穩定的下壓力，避 免因定位件400與上滾輪組35〇間發生滑位而導致下壓力 大幅變化。

easily lifted by the repulsive force of the gears under the lower roller set, so that the roller on the upper roller set The distance between the roller pieces under the lower roller group becomes larger, causing the friction between the upper and lower roller pieces and the glass substrate to decrease, thereby causing abnormal transmission; and (2) the roller piece and the lower roller on the upper roller group The distance between the roller pieces under the group increases due to wear, so that the friction between the glass substrate and the upper and lower roller pieces is reduced, and the glass substrate is not advanced smoothly. Especially in the cleaning process of glass substrates, because the process environment is very humid and slippery, the friction provided by the upper roller is often insufficient: plus the cleaning process often applies a specific chemical maintenance cleaning, which will make the original The process environment, which is already very slippery, will be even worse, and this: The transmissions will often occur frequently. There is no one. [Invention] The present invention - the aspect is the money supply - the type of riding - which increases the friction between the upper and lower roller sets and the glass substrate ‘& reduces the occurrence of transmission anomalies. ',' and then 1296835 are composed of a month-best embodiment, a glass substrate conveying device II, a lower roller set, an upper bearing seat, an upper roller, a group, a positioning frame and a positioning member. The towel and the lower roller set are pivotally connected to the lower bearing seat. ^ The bearing housing is placed on the lower housing. The upper roller (4) is pivoted to the seat' and the lower roller set is halved. The positioning frame is disposed on the upper bearing seat, and the slot is disposed on the top wall of the positioning frame. The positioning member is disposed in the slot and abuts against the upper roller group, so that the ± roller group is subjected to the downward pressure, thereby improving the friction between the upper and lower roller groups and the glass substrate. More specifically, the above-mentioned positioning member is composed of a sleeve, an elastomer, and a piston. Wherein, the sleeve has a piston hole provided at one end thereof. The spring is placed inside the sleeve ::. The piston is partially disposed within the sleeve, and one end of the piston abuts the magazine and the other end passes over the piston bore and abuts the upper roller set. Since the sleeve is restrained by the stroke of the spring, the spring can only be deformed in its axial direction, which will make the downward pressure provided by the positioning member more stable, and the downforce will not be greatly changed due to the spring buckling. According to the above, the positioning member may further have a sleeve thread disposed on the outer side of the sleeve, and the slot may also have a slot thread for engaging the sleeve thread. In this way, the user can easily screw the positioning member into the slot and calculate the downforce applied to the upper roller group according to the degree of screwing into the slot. Continuing the above, the positioning member may further comprise a limiting member disposed at one end of the sleeve opposite the upper roller set. When the sleeve thread is completely screwed into the slot thread, the limiting member abuts against the top wall. In other words, the limiting member limits the distance that the positioning member is screwed into the slot, which ensures that when the limiting member abuts against the top wall, the lowering pressure of the upper roller group is a certain value, which allows the user to calculate without any trouble. The distance that is screwed into the slot. 1296835 ^ In addition, the upper roller set may have an abutment plane against which the positioning member abuts. That is to say, the contact between the positioning member and the upper roller group is a planar contact, which ensures that the upper roller group is subjected to a stable downforce, thereby avoiding a large downforce due to the slippage between the clamp member and the upper roller group. Another aspect of the invention is to provide a glass substrate conveying device, which provides a pair of continuous positioning frames and a plurality of positioning members at both ends of the roller conveying group for reducing unevenness due to wet skid and friction. Abnormalities and damages. According to another preferred embodiment of the present invention, a glass substrate transporting apparatus is composed of a plurality of roller transporting sets, a pair of positioning brackets, and a plurality of positioning members. Wherein the plurality of roller conveying groups are arranged at a distance from each other, and each of the roller conveying groups has a pair of lower bearing seats, and the two ends are respectively connected to the roller groups below the lower bearing housings, respectively disposed thereon The pair of upper bearing housings on the lower bearing housing, and the two ends are respectively pivotally connected to the upper bearing housing and salivating the roller group above the lower roller group. The two positioning brackets are respectively located in the roller conveying group, and both ends are disposed on the bearing seat above each roller conveying group. In addition, the female one positioning frame has a plurality of slots disposed on the top wall thereof. The plurality of positioning members are respectively disposed in the slots, and clamp the two ends of the roller group above each roller conveying group to receive a force, thereby improving the upper and lower roller groups and the glass substrate. Friction between. It is worth noting that the positioning members that resist the ends of each of the upper roller sets will provide the same lower star force to prevent the glass substrate from rotating due to the unequal force at both ends, thereby causing damage to the glass substrate. More specifically, each of the above-mentioned positioning members is composed of a sleeve, an elastic crystal and a live 1296835 plug. Wherein, the sleeve has a piston hole provided at one end thereof. The spring is placed inside the sleeve. The piston is partially disposed within the sleeve with one end of the piston against the spring and the other end passing through the piston bore and against the upper roller set. Since the sleeve is constrained by the stroke of the spring, the spring can only be deformed in its axial direction. As a result, the positioning member can provide a stable downforce to the upper roller set without causing a large change in the downforce due to the spring buckling. According to the above description, each of the positioning members may have a sleeve thread disposed on the outer side of the sleeve, and the slot may also have a slot thread for matching the sleeve thread. In this way, the user can easily screw the positioning member into the slot and calculate the downward pressure applied to the upper roller group depending on the depth of the slot. Continuing to be noted above, each of the positioning members may further include a limiting member disposed at one end of the sleeve opposite the upper roller set. When the sleeve thread is completely screwed into the slot thread, the limiting member abuts against the top wall. In this embodiment, the lengths of the sleeves of each positioning member are equal, so when the limiting member abuts against the top wall, the downward pressure provided by each positioning member to the upper roller group is a certain value, which can be used. There is no need to bother to calculate the distance that is screwed into the slot. In addition, the roller set above each of the roller transport groups can have an abutment plane against which the clamp member abuts. In other words, the contact between the positioning member and the upper roller set is a planar contact, which ensures that the upper roller set is subjected to a stable downforce to avoid a large change in the downforce due to the slippage between the positioning member and the upper roller set. Therefore, the glass substrate conveying apparatus disclosed by the present invention has the following advantages: (1) the friction between the upper and lower roller groups and the glass substrate can be increased, thereby reducing the transmission abnormality; (2) increasing the upper and lower roller groups and the glass The frictional force ensures the balance of the two ends of the glass substrate to avoid damage caused by the rotation of the second material 1296835 substrate; and (3) is particularly suitable for conveying the glass substrate in a wet and slippery process environment. [Embodiment] The present invention increases the friction between the upper glass substrate and the lower glass roller and the glass substrate, so that the abnormality of the transmission is reduced, so that the glass substrate conveying device of the present invention can be applied to the moisture. And in a slippery process environment. The spirit of the present writing will be clearly illustrated by the following description and detailed description. It will be apparent to those skilled in the art that the present invention may be modified and modified without departing from the spirit and scope of the present invention. Referring to Figure 1A, a partial side view of a glass substrate transport apparatus in accordance with a preferred embodiment of the present invention is shown. In Fig. 1A, a glass substrate transporting apparatus is composed of a lower bearing housing 120, a lower roller set 13A, an upper bearing housing 140, an upper roller set 150, a positioning frame 16A, and a positioning member 2''. The lower roller set 130 is pivotally connected to the lower bearing housing 12A. The upper bearing housing 14 is disposed on the lower bearing housing 120. The upper roller set 15 is pivotally connected to the upper bearing block 140 and engages the lower roller set 13A. The positioning frame 16 is disposed on the upper bearing housing 14b and has a slot 162 disposed on the top wall 163 of the positioning frame 160. The positioning member 200 is disposed in the slot 162 and abuts against the upper roller set 15〇, so that the upper roller set 150 is subjected to the downward pressure, thereby improving the friction between the upper roller set 15〇 and the lower roller set 130 and the glass substrate. '..., 1B and ic diagram' respectively indicate the positioning member in the Fig. 〇α diagram = the sectional view before and after the installation. As can be seen from Figs. 1B and 1C, the above-described positioning member 200 is composed of a sleeve 210, a spring 220, and a piston 230. In Ϊ296835, the sleeve 210 has a piston bore 212 that defines a first end 214 of the sleeve 210. The spring 220 is disposed within the sleeve 210. The piston 230 is partially disposed within the sleeve 210, and the first end 234 of the piston 230 abuts against the spring 220, and the second end 232 of the piston 230 passes through the piston bore 212 and abuts the 'upper roller set (Fig. 1A) The upper roller set 150) is depicted. Further, comparing FIGS. 1B and 1C, the spring 220 only produces compression deformation before and after the positioning member 200 is installed, and there is no deformation in other directions (such as frustration or bending), because the sleeve 21 is restrained by the spring 220. The stroke, so the spring 220 can only be deformed in its axial direction, which will make the downward pressure provided by the positioning member 200 relatively stable, and the downforce will not be greatly changed due to the spring 220 being frustrated. In addition, since the magazine is only deformed in its axial direction, according to Hooke's law, the downforce subjected to the upper roller group and the spring deformation will be linear, so the downforce applied to the upper roller group can be easily deformed by the spring. To infer without the need for complicated calculations. Referring to FIGS. 1A and 1C again, in the embodiment, the positioning member 2 can further have a sleeve thread 240 disposed on the outer side of the sleeve 21 , and the slot 162 can also have a slot thread 164 for Fit the sleeve thread 24〇. Thus, the user can easily screw the positioning member 200 into the slot 162 and calculate the downward pressure applied to the upper roller set 15〇 according to the depth of the slot 162. Continuing the above, the clamping member 200 can further include a limiting member 250 disposed on the second end 216 of the sleeve 210 opposite to the upper roller set 150. When the sleeve thread 24 is fully screwed into the slot thread 164, The bit 25 will be just against the top wall 163. In other words, the limiting member 250 limits the distance that the positioning member 2 is screwed into the slot 162, which ensures that when the limiting member 250 abuts against the top wall 163, the downforce that the 150 is subjected to is a constant value. The user is not required to bother; the distance that is screwed into the slot 162 is counted. 12 1296835 Referring to the ID drawing, a cross-sectional view of the positioning member 200 of Fig. 1A against the upper roller set 150 is shown. More specifically, Fig. 1D is a schematic view showing the roller group 150 after the gear 151 is removed on the first drawing. In the 1D view, the upper roller set may have an abutment plane 152 against which the positioning member 200 abuts. Specifically, the upper roller set may have a rectangular block 153 extending through the inner side of the gear, and the positioning member 200 is abutted against the abutting plane 152 on the rectangular block 153. That is to say, the contact between the positioning member 200 and the upper rolling wheel group is a planar contact, which ensures that the upper roller group is subjected to a stable downforce and avoids a large change in the downforce due to the slippage between the positioning member 200 and the upper roller group. Referring to Figures 2 and 2, there are shown partial side elevational and front elevational views of a delivery apparatus for a glass substrate in accordance with another preferred embodiment of the present invention. In Figures 2 and 2, a glass substrate transport apparatus is comprised of a plurality of roller transport groups 310, a pair of locating frames 360, and a plurality of locating members 400. The plurality of roller transport groups 310 are disposed at a distance from each other, and each of the roller transport groups 310 has a pair of lower bearing blocks 320, and the two ends are respectively pivotally connected to the lower roller set 330 of the lower bearing housing 320, The upper bearing housing 340 is disposed on the pair of lower bearing housings 320, and the two ends are respectively pivotally connected to the upper bearing housing 340 and the roller group 350 above the lower roller group 330. The two positioning brackets 360 are respectively located at two ends of the roller conveying group 310, and are disposed on the bearing housing 340 of each roller conveying group 310. In addition, each of the locators 360 has a plurality of slots 362 disposed in the top wall 363 thereof. The plurality of positioning members 400 are respectively disposed in the slots 362, and are respectively pressed against the two ends of the roller group 350 on each roller conveying group 310 to receive a pressure, thereby lifting the upper roller group 350 and the lower portion. Friction between the roller set 330 and the glass 13 1296835 substrate. It is worth noting that the positioning members 400 that resist the ends of each of the upper roller sets will provide the same downforce to prevent the glass from rotating due to unequal forces on both ends, thereby causing the glass substrate to break. In this embodiment, the detailed structure of each of the positioning members 4 is the same as the foregoing, and details are not described herein. However, in this embodiment, the sleeves of each positioning member have the same length, so when the limiting member 4〇2 abuts against the top wall 363, the pressing force provided to the upper roller group by each of the clamping members 400 is constant. A value that prevents the glass substrate from being damaged due to uneven force. In addition, each roller transporting group 310 can have an abutting plane 352 at both ends of the roller set 3·5〇, and the positioning member 4 is pressed against the abutting plane 352. In other words, the contact between the positioning member 4〇〇 and the upper roller set 35〇 is a planar contact, which ensures that the upper roller set 35〇 is subjected to a stable downforce, avoiding the occurrence of slippage between the positioning member 400 and the upper roller set 35. As a result, the downforce has changed dramatically. It will be apparent from the above-described preferred embodiments of the present invention that the application of the present invention has the following advantages. (1) The friction between the upper and lower roller sets and the glass substrate can be increased, thereby reducing the transmission abnormality; (2) increasing the friction between the upper and lower roller groups and the glass substrate while ensuring the balance of the two ends of the glass substrate, Avoid damage due to rotation of the glass substrate; and (3) Particularly suitable for transporting glass substrates in a wet and slippery process environment. Although the present invention has been described above in terms of a preferred embodiment, it is not intended to limit the invention, and those skilled in the art can make various changes and modifications without departing from the scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
