    摘要: A operation program of a robot is simply changed by using a workpiece body without using a master body. The operation program of the robot is corrected by correction data obtained from cameras. When a point of the operation program is desired to be changed to another point, a point on the workpiece body is changed to a changed point. A robot control unit reads the changed point as the coordinate values of the respective axes and changes the same to space coordinate values. Further, the space coordinate values are converted to reference space coordinate values on the master body by an inverse conversion matrix of the correction data. The reference space coordinate values are inversely converted to the coordinate values of respective reference axes. Since the operation program is commanded by the coordinate values of the respective reference axes, the point of the operation program is converted to the another point by using the coordinate values of the respective reference axes. With this method, the operation program can be simply changed without using the master body.

    摘要: First, an operator sequentially teaches the start point A, the end point F and junction points B, C, D, E on the welding path by moving the torch head by jog feed without paying attention to the torch orientation. Next, a reference plane to define the orientation of the torch is specified, and an inclination angle and a forward angle representing the torch orientation be inputted into a robot controller. On the basis of these inputted angle data and the taught data, a basic welding orientation is automatically calculated. Further auxiliary points are set around the junction points B through E each forming corner parts connecting straight lines; tool vectors which may give a smooth torch orientation change through the corner parts are automatically calculated for the auxiliary points and the junction points; and on the basis of the results, a welding program is produced. Among elements which determine the torch orientation, an element relating to the rotation around the torch axis reflects the state at the time of teaching of points A to E.

    摘要: A robot teaching position method for easily modifying an original position of one of a plurality of taught points arranged on a straight line to a modified position moved a distance along the straight line from the original position. An operator selects one of the plurality of taught points, inputs a distance of movement along the straight line from the one taught point to the modified point, and selects two arbitrary taught points arranged on the straight line, using a display device attached to a manual data input device attached to a robot controller. The modified position is determined based on the inputted first taught point, the distance, and the second and third taught points. A robot performs an operation based on the modified position.

    摘要: A sealing gun (31) of a sealant application unit, which controls the flow of the sealant in accordance with the value of an input signal, is attached to the end of a robot arm. The value of a signal applied to the sealant application unit (30) is controlled in association with acceleration/deceleration control of the moving speed of the sealing gun. The moving speed (TSA) of the sealing gun and the flow (SC) of the sealant discharged from the sealing gun are in direct proportion; therefore, the bead width becomes uniform independently of the moving speed (TSA) of the sealing gun.

    摘要: A robot operating method capable of easily performing manual correction of a previously taught teaching point during an automatic robot operation, and of accurately and effectively performing a desired robot operation without the need of employing a visual sensor. After switching is made from an automatic operation mode to a manual operation mode in response to reading of a predetermined command code from a program (S1, S2), a robot tool positioned at a first teaching position is moved to a first working position on a workpiece by a control apparatus which responds to an operation of a remote operation board by an operator, so as to compensate for a dislocation of the teaching point attributable to a positional dislocation of the workpiece (S3), and then a correction data indicative of the results of a manual adjustment is calculated in response to supply of an external signal generated by an operator's operation and is stored in a memory (S4, S5). After completion of robot working at the first working position, second and later teaching points are sequentially corrected based on the correction data in response to reading of a position correcting command code from the program, whereby the robot working is accurately carried out at second and later working positions on the workpiece.

    摘要: A robot which is capable of automatically generating movement path patterns based on taught data and in which a data teaching operation associated with pattern generation is simplified and no special data teaching is required even when the pitch between pattern segments is to be changed. During a manual robot operation, when start and end points (P0, Pn) of a spraying pattern which consists of a series of subpatterns, and a first cornering point (P1) of a first subpattern are taught to the robot, taught data representing these three point is stored in a robot control unit, together with a spraying command code and a spraying pitch (d) taught separately. During a playback robot operation, in response to the spraying command code, a vector (A) directed from the start point (P0) to the first cornering point (P1) and a vector (D) directed from the first cornering point (P1) to a second cornering point (P2) are calculated based on the taught data and the pitch. Each time a plasma jet torch reaches one of the start point, first to third cornering points and end point of a subpattern, the end point of a corresponding one of the vector (A), the vector (B), and a vector derived by reversing the vector (A), all having a start point thereof coinciding with the reached point, is determined as a new target position, thereby generating a spraying pattern.

    摘要: A system for setting a tool coordinate system brings directions ( , , ) of respective basic axes of the tool coordinate system into coincidence with directions (X, Y, Z) of basic axes of a robot reference coordinate system. A tool center point (TCP) serves as an origin, and the system causes a robot to memorize metric values on each motion axis of the robot at the moment of coincidence as setting information for setting the tool coordinate system. The system uses this setting information as information for subsequent robot motion. With the present invention, the setting of tool coordinates, which was a troublesome operation in the prior art, can be performed easily and accurately through a simple method.
