[發明所欲解決之課題] 在如專利文獻1中記載的搬送裝置那樣的搬送裝置中，若使第一臂部及第二臂部的長度變長，則可使搬送臂伸長時的搬送臂的前後方向的長度變長，因此可將搭載在手的半導體晶片在前後方向上搬送至離門型框架更遠的位置為止。另一方面，在所述搬送裝置的情況下，若使第一臂部及第二臂部的長度變長，則當伸長的搬送臂收縮時，產生第一臂部與第二臂部的連結部分、或第二臂部與手的連結部分干涉門型框架的支柱的擔憂。[The problem to be solved by the invention] In a transfer device such as the transfer device described in Patent Document 1, if the lengths of the first arm portion and the second arm portion are increased, the length of the transfer arm in the front-rear direction when the transfer arm is extended can be increased. Therefore, the semiconductor wafer mounted on the hand can be conveyed to a position farther from the gate frame in the front-rear direction. On the other hand, in the case of the above-mentioned conveying device, if the lengths of the first arm portion and the second arm portion are increased, when the extended conveying arm contracts, the connection between the first arm portion and the second arm portion occurs. There is a concern that part, or the connecting part of the second arm and the hand, interferes with the pillars of the portal frame.

因此，本發明的課題在於提供一種產業用機器人，包括具有以在左右方向上空開間隔的狀態配置的兩根支柱的門型的門型框架，即便可將搭載在手的搬送對象物在前後方向上搬送至離門型框架更遠的位置為止，也可以防止臂與支柱的干涉。 [解決問題的技術手段]Therefore, an object of the present invention is to provide an industrial robot including a portal frame having two pillars spaced apart from each other in the left-right direction, even if the object to be transported in the hand can be carried in the front-rear direction. It is also possible to prevent the interference between the arm and the column by transferring it up to a position farther from the door frame. [Technical means to solve the problem]

為了解決所述課題，本發明的產業用機器人的特徵在於包括：手，搭載搬送對象物；臂，手可轉動地連結在所述臂的前端側，並且在水平方向上伸縮；臂支撐部，臂的基端側可轉動地連結在臂支撐部；以及門型的門型框架，可升降地保持臂支撐部；臂包括：第一臂部，基端側可轉動地連結在臂支撐部；以及第二臂部，基端側可轉動地連結在第一臂部的前端側，並且供手可轉動地連結在前端側；若將水平方向中的規定的方向設為左右方向，將與上下方向及左右方向正交的方向設為前後方向，則門型框架包括以在左右方向上空開間隔的狀態配置的兩根支柱，手及臂在左右方向上配置在兩根支柱之間，若將第一臂部相對於臂支撐部的轉動中心設為第一轉動中心，將第二臂部相對於第一臂部的轉動中心設為第二轉動中心，將手相對於第二臂部的轉動中心設為第三轉動中心，將左右方向上的兩根支柱之間的中心位置設為支柱間中心，則第一轉動中心與第二轉動中心的距離、和第二轉動中心與第三轉動中心的距離變成相等，當第一臂部相對於臂支撐部轉動且第二轉動中心在前後方向上配置在與第一轉動中心相同的位置時，第二轉動中心配置在與支柱間中心相比更靠左右方向的一側的位置，第一轉動中心配置在與支柱間中心相比更靠左右方向的另一側的位置。In order to solve the above-mentioned problems, the industrial robot of the present invention is characterized by comprising: a hand on which an object to be conveyed is mounted; an arm, the hand being rotatably connected to the front end side of the arm and extending and retracting in the horizontal direction; and an arm support portion, The base end side of the arm is rotatably connected to the arm support portion; and a portal-shaped door frame holds the arm support portion in a liftable manner; the arm includes: a first arm portion, the base end side is rotatably connected to the arm support portion; and the second arm part, the base end side is rotatably connected to the front end side of the first arm part, and the hand is rotatably connected to the front end side; The direction perpendicular to the left-right direction is defined as the front-rear direction, and the portal frame includes two pillars arranged in a spaced state in the left-right direction, and the hand and the arm are arranged between the two pillars in the left-right direction. The rotation center of the first arm portion relative to the arm support portion is referred to as the first rotation center, the rotation center of the second arm portion relative to the first arm portion is referred to as the second rotation center, and the rotation center of the hand relative to the second arm portion is referred to as the second rotation center. Set as the third rotation center, and set the center position between the two pillars in the left-right direction as the center between pillars, the distance between the first rotation center and the second rotation center, and the distance between the second rotation center and the third rotation center. When the distance becomes equal, when the first arm portion rotates relative to the arm support portion and the second rotation center is arranged at the same position as the first rotation center in the front-rear direction, the second rotation center is arranged closer to the center between the struts. As for the position on one side in the left-right direction, the first rotation center is arranged on the other side in the left-right direction than the center between the struts.

在本發明的產業用機器人中，若將第一臂部相對於臂支撐部的轉動中心設為第一轉動中心，將第二臂部相對於第一臂部的轉動中心設為第二轉動中心，將手相對於第二臂部的轉動中心設為第三轉動中心，則第一轉動中心與第二轉動中心的距離、和第二轉動中心與第三轉動中心的距離變成相等。另外，在本發明中，若將左右方向上的兩根支柱之間的中心位置設為支柱間中心，則當第一臂部相對於臂支撐部轉動且第二轉動中心在前後方向上配置在與第一轉動中心相同的位置時，第二轉動中心配置在與支柱間中心相比更靠左右方向的一側的位置，另一方面，第一轉動中心配置在與支柱間中心相比更靠左右方向的另一側的位置。In the industrial robot of the present invention, the rotation center of the first arm portion relative to the arm support portion is referred to as the first rotation center, and the rotation center of the second arm portion relative to the first arm portion is referred to as the second rotation center , and set the rotation center of the hand relative to the second arm as the third rotation center, the distance between the first rotation center and the second rotation center and the distance between the second rotation center and the third rotation center become equal. In addition, in the present invention, if the center position between the two struts in the left-right direction is defined as the center between struts, when the first arm portion rotates with respect to the arm support portion, the second rotation center is arranged in the front-rear direction at When the position is the same as the first rotation center, the second rotation center is arranged on the left-right side of the center between the struts, while the first rotation center is arranged closer than the center between the struts. The position of the other side in the left and right direction.

因此，在本發明中，即便使第一臂部及第二臂部的長度變長，使臂伸長時的臂的前後方向的長度變長，當伸長的臂收縮時，也可以防止第一臂部與第二臂部的連結部分、或第二臂部與手的連結部分干涉支柱。因此，在本發明中，即便可將搭載在手的搬送對象物在前後方向上搬送至離門型框架更遠的位置為止，也可以防止臂與支柱的干涉。Therefore, in the present invention, even if the lengths of the first arm portion and the second arm portion are increased, and the length of the arm in the front-rear direction when the arm is extended is increased, the first arm can be prevented from being contracted when the extended arm is contracted. The connecting portion of the arm portion and the second arm portion or the connecting portion of the second arm portion and the hand interferes with the strut. Therefore, in the present invention, even if the object to be conveyed mounted on the hand can be conveyed to a position farther from the portal frame in the front-rear direction, the interference between the arm and the support can be prevented.

在本發明中，優選手在收縮狀態的臂伸長時，以手的前端朝向前後方向的一側的固定的姿勢朝前後方向的一側進行直線移動，若將門型框架的前後方向的中心位置設為框架中心，則第一轉動中心配置在與框架中心相比更靠前後方向的另一側的位置。若如此構成，則例如可使搭載在手的搬送對象物及手在前後方向上退避至離搬送對象物被產業用機器人搬送的規定的裝置更遠的位置為止。In the present invention, it is preferable that when the arm in the retracted state is extended, the hand moves linearly to the front-rear direction side with the front end of the hand facing the front-rear direction side. As the frame center, the first rotation center is arranged on the other side in the front-rear direction from the frame center. With this configuration, for example, the transport object mounted on the hand and the hand can be retracted in the front-rear direction to a position farther from a predetermined device to which the transport object is transported by the industrial robot.

在本發明中，優選手的前後方向的長度比第一臂部的長度及第二臂部的長度長。若如此構成，則例如當在搬送對象物被產業用機器人搬送的規定的處理裝置的蓋形成有手可進出，但臂無法進出的大小的開口部時，可防止處理裝置的蓋與臂的干涉，並將搭載在手的搬送對象物搬送至處理裝置的更裡側為止。In this invention, it is preferable that the length of the front-back direction of a hand is longer than the length of a 1st arm part and the length of a 2nd arm part. With this configuration, for example, when the cover of a predetermined processing apparatus in which the object to be conveyed is conveyed by an industrial robot is formed with an opening of a size that allows the hand to enter and exit, but the arm cannot enter and exit, interference between the cover of the processing apparatus and the arm can be prevented. , and transport the object to be transported on the hand to the further back side of the processing device.

在本發明中，優選產業用機器人包括以可實現將上下方向作為轉動的軸方向的門型框架的轉動的方式，載置門型框架的基底構件，手在臂伸縮時，以手的前端朝向前後方向的一側的固定的姿勢在前後方向上進行直線移動，若將門型框架相對於基底構件的轉動中心設為第四轉動中心，將手的左右方向的中心位置設為手中心，則第一轉動中心配置在左右方向上與第四轉動中心錯開的位置，手中心配置在左右方向上與第四轉動中心相同的位置。In the present invention, it is preferable that the industrial robot includes a base member on which the portal frame is placed so that the portal frame can be rotated with the vertical direction as the axis direction of the rotation, and when the arm is extended and retracted, the front end of the hand faces The fixed posture of one side in the front-rear direction moves linearly in the front-rear direction. If the rotation center of the door frame relative to the base member is the fourth rotation center, and the center position of the hand in the left-right direction is the hand center, the first The first rotation center is arranged at a position shifted from the fourth rotation center in the left-right direction, and the hand center is arranged at the same position as the fourth rotation center in the left-right direction.

若如此構成，則手中心配置在左右方向上與第四轉動中心相同的位置，因此即便第一轉動中心配置在左右方向上與第四轉動中心錯開的位置，例如和手中心配置在左右方向上與第一轉動中心相同的位置的情況相比，對搬送對象物進行搬送時的產業用機器人的控制也變得容易。 [發明的效果]With this configuration, the center of the hand is arranged at the same position as the fourth rotation center in the left-right direction. Therefore, even if the first rotation center is arranged at a position shifted from the fourth rotation center in the left-right direction, for example, the center of the hand is arranged in the left-right direction. Compared with the case where the first rotation center is at the same position, the control of the industrial robot at the time of conveying the conveying object becomes easier. [Effect of invention]

如上所述，在本發明中，在包括具有以在左右方向上空開間隔的狀態配置的兩根支柱的門型的門型框架的產業用機器人中，即便可將搭載在手的搬送對象物在前後方向上搬送至離門型框架更遠的位置為止，也可以防止臂與支柱的干涉。As described above, in the present invention, in the industrial robot including the portal frame having the two pillars spaced apart from each other in the left-right direction, even if the object to be transported in the hand can be It is also possible to prevent the interference between the arm and the column even when it is conveyed to a position farther from the door frame in the front-rear direction.

若第一臂部10相對於臂支撐部5轉動，則轉動中心C2如圖4所示，當從上下方向觀察時，在將轉動中心C1作為曲率中心，並且朝左側鼓起的半圓弧狀的假想線VL上穿過。若將左右方向上的兩根支柱16之間的中心位置設為支柱間中心CL1，則如圖4所示，當第一臂部10相對於臂支撐部5轉動且轉動中心C2在前後方向上配置在與轉動中心C1相同的位置時，轉動中心C2配置在與支柱間中心CL1相比更靠左側的位置。即，當轉動中心C2在前後方向上配置在與轉動中心C1相同的位置時，臂4以第一臂部10和第二臂部11的連結部分配置在與支柱間中心CL1相比更靠左側的位置的方式收縮。另外，此時，當從上下方向觀察時，轉動中心C1與轉動中心C3重疊。When the first arm portion 10 is rotated relative to the arm support portion 5, as shown in FIG. 4, the rotation center C2 is in a semi-circular arc shape bulging to the left with the rotation center C1 as the center of curvature when viewed from the up-down direction. traverses on the imaginary line VL. Assuming that the center position between the two pillars 16 in the left-right direction is the center between pillars CL1, as shown in FIG. When arrange|positioned at the same position as the rotation center C1, the rotation center C2 is arrange|positioned at the left side rather than the center CL1 between pillars. That is, when the rotation center C2 is arranged at the same position as the rotation center C1 in the front-rear direction, the arm 4 is arranged on the left side of the center CL1 between the struts at the connecting portion of the first arm portion 10 and the second arm portion 11 position in a way that shrinks. In addition, at this time, the rotation center C1 and the rotation center C3 overlap when viewed from the up-down direction.

另外，轉動中心C1配置在與支柱間中心CL1相比更靠右側的位置。即，臂支撐部5和第一臂部10的連結部分配置在與支柱間中心CL1相比更靠右側的位置。另外，如圖2所示，若將門型框架6的前後方向的中心位置設為框架中心CL2，則轉動中心C1配置在與框架中心CL2相比更靠後側的位置。另外，轉動中心C1在左右方向上，配置在與門型框架6相對於基底構件7的轉動中心C4錯開的位置。具體而言，轉動中心C1配置在與轉動中心C4相比更靠右側的位置。另外，轉動中心C1配置在與轉動中心C4相比更靠後側的位置。轉動中心C4配置在與支柱間中心CL1相比更靠右側的位置，並且配置在與框架中心CL2相比更靠後側的位置。本形態的轉動中心C4是第四轉動中心。Moreover, the rotation center C1 is arrange|positioned at the right side rather than the center CL1 between pillars. That is, the connection part of the arm support part 5 and the 1st arm part 10 is arrange|positioned to the right side rather than the center CL1 between pillars. Moreover, as shown in FIG. 2, if the center position of the front-back direction of the portal frame 6 is set as the frame center CL2, the rotation center C1 is arrange|positioned at the back side rather than the frame center CL2.

Moreover, the rotation center C1 is arrange|positioned at the back side rather than the rotation center C4. The rotation center C4 is arranged on the right side of the inter-pillar center CL1, and is arranged on the rear side of the frame center CL2. The rotation center C4 of this aspect is the fourth rotation center.

若將在臂4伸縮時，以手3的前端朝向前側的固定的姿勢在前後方向上進行直線移動的手3的左右方向的中心位置設為手中心CL3，則手中心CL3在左右方向上配置在與轉動中心C4相同的位置。即，在臂4伸縮時，若從上下方向觀察，則手中心CL3在轉動中心C4上穿過。When the arm 4 is extended and retracted, the hand center CL3 is arranged in the left-right direction when the center position in the left-right direction of the hand 3 that moves linearly in the front-rear direction with the front end of the hand 3 facing the front is fixed as the hand center CL3. at the same position as the center of rotation C4. That is, when the arm 4 expands and contracts, the hand center CL3 passes through the rotation center C4 when viewed from the up-down direction.

（本形態的主要效果） 如以上說明那樣，在本形態中，轉動中心C1與轉動中心C2的距離L1、和轉動中心C2與轉動中心C3的距離L2變成相等。另外，在本形態中，當第一臂部10相對於臂支撐部5轉動且轉動中心C2在前後方向上配置在與轉動中心C1相同的位置時，轉動中心C2配置在與支柱間中心CL1相比更靠左側的位置，另一方面，轉動中心C1配置在與支柱間中心CL1相比更靠右側的位置。(The main effect of this form) As described above, in this embodiment, the distance L1 between the rotation center C1 and the rotation center C2 and the distance L2 between the rotation center C2 and the rotation center C3 are equal. In addition, in this aspect, when the first arm portion 10 is rotated relative to the arm support portion 5 and the rotation center C2 is arranged at the same position as the rotation center C1 in the front-rear direction, the rotation center C2 is arranged at the same position as the center CL1 between the struts On the other hand, the rotation center C1 is located more to the right than the center CL1 between the struts.

因此，在本形態中，即便使第一臂部10及第二臂部11的長度變長，使臂4伸長時的臂4的前後方向的長度變長，當伸長的臂4收縮時，也可以防止第一臂部10與第二臂部11的連結部分、或第二臂部11與手3的連結部分干涉兩根支柱16。因此，在本形態中，即便可將搭載在手3的晶片2朝前側搬送至離門型框架6更遠的位置為止，也可以防止臂4與支柱16的干涉。Therefore, in the present embodiment, even if the lengths of the first arm portion 10 and the second arm portion 11 are increased, and the length of the arm 4 in the front-rear direction when the arm 4 is extended is increased, when the extended arm 4 is contracted, the The connection portion between the first arm portion 10 and the second arm portion 11 or the connection portion between the second arm portion 11 and the hand 3 can be prevented from interfering with the two struts 16 . Therefore, in this aspect, even if the wafer 2 mounted on the hand 3 can be transferred to a position farther from the gate frame 6 toward the front side, the arm 4 and the support column 16 can be prevented from interfering with each other.

在本形態中，轉動中心C1配置在與框架中心CL2相比更靠後側的位置。因此，在本形態中，當使臂4收縮至圖3中所示的狀態為止時，可使搭載在手3的晶片2及手3在前後方向上退避至離配置在機器人1的前側的處理裝置更遠的位置為止。因此，在本形態中，當機器人1回旋時，容易防止晶片2及手3與處理裝置的干涉。In this form, the rotation center C1 is arrange|positioned at the rear side rather than the frame center CL2. Therefore, in the present embodiment, when the arm 4 is retracted to the state shown in FIG. 3 , the wafer 2 and the hand 3 mounted on the hand 3 can be retracted in the front-rear direction away from the processing arranged on the front side of the robot 1 until the device is farther away. Therefore, in this aspect, when the robot 1 turns, it is easy to prevent the wafer 2 and the hand 3 from interfering with the processing apparatus.

在本形態中，手3的前後方向的長度比第一臂部10的長度及第二臂部11的長度長。因此，在本形態中，例如當在構成處理裝置的後表面的蓋形成有手3可進出，但臂4無法進出的大小的開口部時，可防止處理裝置的蓋與臂4的干涉，並將搭載在手3的晶片2搬送至處理裝置的更裡側（前側）為止。In this aspect, the length of the hand 3 in the front-rear direction is longer than the length of the first arm portion 10 and the length of the second arm portion 11 . Therefore, in the present embodiment, when, for example, the cover constituting the rear surface of the processing apparatus is formed with an opening of a size that allows the hand 3 to enter and exit, but the arm 4 cannot enter and exit, the interference between the cover of the processing apparatus and the arm 4 can be prevented, and the The wafer 2 mounted on the hand 3 is transported to the further back side (front side) of the processing apparatus.

在本形態中，手中心CL3在左右方向上配置在與轉動中心C4相同的位置。因此，在本形態中，即便轉動中心C1在左右方向上配置在與轉動中心C4錯開的位置，例如和手中心CL3在左右方向上配置在與轉動中心C1相同的位置的情況相比，搬送晶片2時的機器人1的控制也變得容易。In this form, the hand center CL3 is arrange|positioned at the same position as the rotation center C4 in the left-right direction. Therefore, in the present embodiment, even if the rotation center C1 is arranged at a position shifted from the rotation center C4 in the left-right direction, for example, compared with the case where the hand center CL3 is arranged at the same position as the rotation center C1 in the left-right direction, the wafer is transferred. The control of the robot 1 at 2 o'clock also becomes easy.
