Abstract
A machine learning device which learns an operation of a laminated core manufacturing apparatus for stacking a plurality of core sheets to manufacture a laminated core, wherein the machine learning device includes a state observation unit which observes states of the core sheets and the laminated core manufacturing apparatus; and a learning unit which updates a manipulated variable for stacking the core sheets, on the basis of a state variable observed by the state observation unit.
Claims12
A laminated core manufacturing apparatus, comprising:
- a robot having a hand portion configured to stack core sheets having a predetermined shape one by one or in groups of at least two core sheets to manufacture a laminated core;
- and
- a robot vision system attached to the hand portion, wherein
- the laminated core manufacturing apparatus is configured to manufacture the laminated core by stacking the core sheets based on
- (1) shape data of the core sheets detected by the robot vision system,
- (2) operation data of the laminated core manufacturing apparatus, and
- (3) time data for stacking the core sheets.
A machine learning method of learning an operation of a laminated core manufacturing apparatus for stacking a plurality of core sheets to manufacture a laminated core, the method comprising:
- observing states of the core sheets and the laminated core manufacturing apparatus;
- and
- updating a manipulated variable for stacking the core sheets, on the basis of a state variable obtained in the observing, the state variable representing
- (1) shape data of the core sheets,
- (2) operation data of the laminated core manufacturing apparatus, and
- (3) time data for stacking the core sheets,
- wherein
- the laminated core manufacturing apparatus comprises a robot comprising a robot vision system attached to one of a hand portion and an area which provides a broad view of a workspace, and
- in said observing, the shape data of the core sheets are received from the robot vision system.
