Machine learning device for learning assembly operation and component assembly system

A machine learning device for learning an assembly operation in which at least one operating machine assembles a first component and a second component to produce an assembly, the machine learning device comprising:

• a state observation unit for observing state variables that include at least one of the state of the assembly, a time required to assemble the first component and the second component, and information on a force required to assemble the first component and the second component, the result of a continuity test on the assembly, and at least one of position and posture command values for at least one of the first component and the second component before the assembly operation, speed and force command values for the assembly operation;
• and
• a learning unit for learning, in a related manner, at least one of the state of the assembly, the time required to assemble the first component and the second component, and the information on the force required to assemble the first component and the second component, the result of the continuity test on the assembly, and at least one of the position and posture command values for at least one of the first component and the second component before the assembly operation, and the speed and force command values for the assembly operation, observed by the state observation unit.
