Abstract

PURPOSE:To perform diagnosis of abnormality of a robot as a work is carried out by providing an irradiating means to irradiate space with a pair of lights crossing each other and providing a robot with a target to simultaneously cut off or transmit a pair of the lights. CONSTITUTION:A hand to which a target 15 is attached is moved and a specified position wherein a pair of lights generated by an optical fiber switch 11 and crossing each other are both cut off by the target 15 is previously taught. The specified position is contained in a working program at a specified period. In this case, the three wrist shafts being fourth-sixth wrists for rotation, bending, and inclination of a wrist are brought into a posture approximately equal to right angles with each other. When dislocation occurs, the target 15 is easy to displace from an intersection between lights. When a work is started, the target 15 passes the intersection between the lights at a specified period and when light is cut off, as taught, by the target 15, it is judged to be no abnormality and the robot continues a work. When one or both of the lights are not cut off, it is judged to be dislocation and to bring a work to a stop.

Conventionally, the following method has been used for inspecting the presence or absence of misalignment. As shown in FIG. 5, the alignment jig 2 for alignment is attached to the hand 1 of the robot, while the fixing jig 3 having the same shape as the alignment jig 2 is provided on the floor surface through the columns 4. Then, the turning angles of the respective turning parts of the robot when the matching jig 2 is opposed to the fixing jig 3 and the entire facing surface is brought into contact with each other are stored in advance. And
Each rotating part of the robot is set to the same angle as the stored rotating angle, and the fixing jig 3 and the aligning jig 4 at this time are set.
Detect the deviation with the eye or visually with a gap gauge. At this time, if the fixing jig 3 and the aligning jig 2 are in full contact with each other without any gap, there will be no displacement.

However, in order to detect the positional deviation, it is necessary to temporarily stop the work by the robot and stop the line, and then start the program for the positional deviation inspection. Work is required by the worker to inspect the deviation. Further, since the fixing jig is arranged near the joint of the robot for checking, the detection accuracy is lower than that for checking with the arm of the robot extended.
