將液晶用的玻璃基板或半導體晶圓等之薄片狀的工件 . 搬進搬出儲存櫃之多關節機械手，已進展爲大型化，要求 〇 處理基板的片數要增加並且要在短時間內處理，又爲了要 提高基板的良品率，還要求盡力抑制來自機械手的粉塵。 因而，機械手儘管配置基板的儲存櫃變成直達頂棚程度的 高度導致設備本身大型化，但實現高速、高精度、低粉塵 乃是最大的課題。一方面，大型化的設備，爲了要保持周 圍的乾淨度，必須要投資大金額的設備，因而，最好是令 儲存櫃配置更多的基板並進行處理。另外，最好是縮小多 關節機械手的機體，縮小迴旋半徑以使不會干涉到工廠中 所配置的裝置。 -6- 200932456 另外，液晶基板或半導體晶圓的生產片數逐年增加中 ，爲了要提升生產速度，機械手則被要求搬送的流量。然 而，機械手包含有機械零件，因而必須要維修，維修時間 也成爲關係到流量的因素，最好是很容易就可以進行維修 〇 . 然而，習知的多關節機械手係以臂基端突出移動面而 與搬送基板相對向的方式來配置的構造，故會發生無法防 Φ 範來自上下移動機構的粉塵導致微細的粉塵堆積在基板上 的問題。 另外，臂藉利用上下移動機構來往下方移動的情況， 臂的支撐構件會與台座起衝突，故會發生無法移動到上下 移動機構的最下面爲止，可動範圍變小的問題，且會發生 液晶基板或半導體晶圓搬進搬出之儲存櫃的高度變高的問 - 題。進一部來說明，儲存櫃的高度會受限於工廠建築物的 _ 高度，故會發生面板或基板的配置片數，因上下移動機構 ® 的可動範圍變小而減少，使生產速度下降的問題。 另外，在臂基端設有電動機或皮帶輪，故會成爲上下 方向很厚的構造。因而，會發生儲存櫃內液晶基板或半導 體晶圓的配置間隔不得不加大的問題。也就是會發生儲存 櫃內所可以配置之面板或基板的片數變少致使生產速度下 降的問題。爲了要避免這個問題，雖想要在利用上下移動 機構進行搬進搬出時改變臂的高度，但此情況，由於令臂 上下移動的順序反覆進行，故會發生耗費時間致使作業時 間變長的問題。 200932456 另外，習知的多關節機械手係向上下同軸地配置臂基 端的構造。因而，配置在臂基端之屬於機構組件之電動機 或皮帶輪要進行更換的話’不得不採用拆下其中一方的臂 後再進行更換等的方法，故會發生維修時間很長致使生產 性降低的問題。 _ 另外，習知的多關節機械手係1個柱體上利用移動機 構來移動支撐構件，故儲存櫃高度直達頂棚部程度’則當 0 然必須加長柱體長度，剛性會降低，並且配置在內部之移 動機構的導引機構也必須設成符合柱體的長度。然而’加 長導引機構的情況，導引精度會因增長而降低，故利用移 動機構來移動之支撐構件的移動精度降低，且載置在臂先 端的手部8之液晶基板或半導體晶圓的定位精度降低，會 發生引起基板或晶圓與儲存櫃起衝突導致良品率降低的問 - 題。 發明係鑑於上述的問題點而提案，其目的是提供將防 φ 止來自上下移動軸的粉塵對基板的污染，並且讓生產性提 高之液晶用的玻璃基板或半導體晶圓等之薄片狀的工件搬 進搬出儲存櫃之多關節機械手。 <用以解決課題之手段> 爲了要解決上述問題，本發明的構成如以下所述。 本發明的申請專利範圍第1項所述之多關節機械手， 是一種由載置搬送物之手部、及與前述手部相連結且具備 至少2個以上的迴轉關節並以朝向1個方向移動前述手部 -8 -

[Prior Art] Conventionally, the proposed multi-joint robot system biases the center of rotation of the shoulder joint and the center of rotation of the pedestal to reduce the radius of gyration of the multi-joint manipulator when the pedestal is rotated (for example, Reference is made to Japanese Patent Document 1). As shown in Fig. 5, the conventional multi-joint robot 1 is rotatably coupled by the joint portions 3, 4, and 5, and transmits the turning force of the turning drive source, so that the arm 2 that performs the desired operation has two sets. The composition is configured such that the center axis of rotation of the joint portion 3 provided at the base end of the two sets of arms 2 is arranged up and down (or in the axis-direction). The multi-joint robot 1 includes two sets of arms 2, one of which is for supply and the other for take-out, and can simultaneously supply the workpiece 9 and take out other workpieces 9. . Further, the conventional multi-joint robot 1 is configured by the arm 2 for holding the hand 8 of the workpiece 9 linearly movable in the take-out/supply direction of the workpiece 9 indicated by the arrow X in the figure. Further, the conventional multi-joint robot 1 includes a moving member 11 (hereinafter referred to as an up-and-down moving mechanism 11) for moving the support member 10 on which the arm 2 is mounted up and down, and the vertical position of the arm 2 can be adjusted. Further, the pedestal 13 of the upper and lower moving mechanism 11 is rotatably provided, and is formed to swing the -4-200932456 joint robot 1 to change the direction. Further, in the multi-joint robot 1 of the present embodiment, in the direction indicated by the arrow Y in the figure, that is, in the direction in which the direction of movement of the hand 8 and the vertical movement direction of the support member 10 are perpendicular to each other, The pedestal 13 is movably mounted on the table 14, and the position of the up-and-down moving mechanism 11 can be adjusted. Further, the conventional two-joint robot 1 is provided with two sets of arms 2, for example, a plurality of joint portions, that is, the multi-joint robot 1 is composed of a horizontal multi-joint φ-type robot. The arm 2 in the present embodiment includes a first arm 6 (hereinafter referred to as an upper wrist 6)' and a second arm 7 (hereinafter referred to as a front wrist 7) coupled to the upper wrist 6, and is coupled to the front wrist 7. The hand 8 of the workpiece 9 is held. The proximal end of the upper wrist 6 is coupled to the support member 1B by a drive shaft to constitute a rotatable joint portion 3 (hereinafter referred to as a shoulder joint portion 3). The shoulder joint portion 3 serves as the joint portion 3 of the base end of the arm 2. Further, the distal end of the upper wrist 6 and the proximal end of the front wrist 7 are coupled by a drive shaft to constitute a joint portion 4 (hereinafter referred to as an elbow joint portion 4) that can be rotated. Further, the distal end of the front wrist 7 and the hand 8 are coupled by a drive shaft to constitute a rotatable joint portion 5 (hereinafter referred to as a hand joint portion 5). The center axis of rotation of the shoulder joint portion 3 is arranged on the same axis, and the upper and lower directions are opposite to each other. The arm 2 rotates the shoulder joint portion 3, the elbow joint portion 4, and the hand joint portion 5 by a turning drive source (not shown) to move the hand 8 in the workpiece take-out/supply direction. At this time, the arm 2 is linearly moved between the extended position where the upper wrist 6 and the front wrist 7 are fully extended and the retracted position where the upper wrist 6 and the front wrist 7 are folded in the direction in which the hand 8 is oriented in one direction. -5- 200932456, for expansion and contraction. Here, the conventional multi-joint robot 1 is in such a manner that the center of the workpiece 9 held by the hand 8 at the retracted position of the arm 2 shown in Fig. 6 coincides with the center of rotation of the pedestal 13 design. Further, the center of rotation of the shoulder joint portion 4 and the center of rotation of the pedestal 13 are displaced in a direction perpendicular to the direction of movement of the hand portion 8. When the pedestal 13 is rotated, the elbow joint portion 4 or the hand portion 8 does not protrude much. The zero-area circle 15 necessary for the circumference of the joint manipulator 1 can reduce the radius of gyration of the multi-joint robot 1. Patent Document 1: Japanese Patent Laid-Open No. 2001- 2742 1 8 (pages 4 to 5, first and second figures) [Summary of the Invention] <Problems to be Solved by the Invention> - Glass substrate or semiconductor crystal for liquid crystal A flaky workpiece such as a circle. The multi-joint robot that has been moved in and out of the storage cabinet has been enlarged to require an increase in the number of substrates to be processed and to be processed in a short period of time, in order to increase the yield of the substrate. It is also required to try to suppress the dust from the robot. Therefore, although the robot has a large height of the storage cabinet in which the substrate is placed so as to reach the ceiling, achieving high speed, high precision, and low dust is the biggest problem. On the one hand, large-scale equipment must invest in a large amount of equipment in order to maintain cleanliness around it. Therefore, it is better to have more substrates in the storage cabinet and process them. In addition, it is preferable to reduce the body of the multi-joint robot and reduce the radius of the gyration so as not to interfere with the device configured in the factory. -6- 200932456 In addition, the number of productions of liquid crystal substrates or semiconductor wafers has increased year by year. In order to increase the production speed, the robot is required to carry the flow rate. However, the robot contains mechanical parts and must be repaired. The repair time also becomes a factor related to the flow. It is best to carry out the repairs easily. However, the conventional multi-joint robots protrude from the base of the arm. Since the moving surface is disposed so as to face the transport substrate, there is a problem in that it is impossible to prevent fine dust from being deposited on the substrate due to dust from the vertical moving mechanism. Further, when the arm is moved downward by the vertical movement mechanism, the support member of the arm collides with the pedestal, so that the movable portion cannot be moved to the lowermost position of the vertical movement mechanism, and the liquid crystal substrate may occur. Or the question of the height of the storage cabinet in which the semiconductor wafer is moved in and out. In addition, the height of the storage cabinet is limited by the height of the factory building, so the number of panels or substrates can be reduced, and the movable range of the upper and lower moving mechanism® is reduced, which reduces the production speed. . Further, since the motor or the pulley is provided at the base end of the arm, the structure is thick in the up and down direction. Therefore, there arises a problem that the arrangement interval of the liquid crystal substrate or the semiconductor wafer in the storage cabinet has to be increased. That is, there is a problem that the number of panels or substrates that can be disposed in the storage cabinet is reduced, resulting in a decrease in production speed. In order to avoid this problem, it is desirable to change the height of the arm when moving in and out by the vertical movement mechanism. However, in this case, since the order of moving the arm up and down is repeated, it takes time and the working time becomes long. . In addition, the conventional multi-joint robot is configured such that the base end of the arm is disposed coaxially upward and downward. Therefore, if the motor or the pulley that is disposed at the base end of the arm is to be replaced, it is necessary to remove the arm of one of the arms and then replace it, so that the maintenance time is long and the productivity is lowered. . _ In addition, the conventional multi-joint robot system uses a moving mechanism to move the support member on one cylinder, so the height of the storage cabinet reaches the ceiling level. When 0, the length of the cylinder must be lengthened, the rigidity is lowered, and the configuration is The guiding mechanism of the internal moving mechanism must also be set to match the length of the cylinder. However, in the case of the lengthening guide mechanism, the guiding accuracy is lowered due to the increase, so that the movement accuracy of the supporting member moved by the moving mechanism is lowered, and the liquid crystal substrate or the semiconductor wafer of the hand 8 placed at the tip end of the arm is lowered. The positioning accuracy is lowered, and a problem occurs in which the substrate or the wafer collides with the storage cabinet to cause a decrease in the yield. The present invention has been made in view of the above-mentioned problems, and an object of the invention is to provide a sheet-like workpiece such as a glass substrate or a semiconductor wafer for preventing liquid crystal contamination from the upper and lower moving shafts and preventing productivity from being improved. A multi-joint robot that moves in and out of the storage cabinet. <Means for Solving the Problem> In order to solve the above problems, the configuration of the present invention is as follows.
