Abstract
Aspects of the disclosed technology provide an Artificial Intelligence Process Control (AIPC) for automatically detecting errors in a manufacturing workflow of an assembly line process, and performing error mitigation through the update of instructions or guidance given to assembly operators at various stations. In some implementations, the disclosed technology utilizes one or more machine-learning models to perform error detection and/or propagate instructions/assembly modifications necessary to rectify detected errors or to improve the product of manufacture.
Claims20
A method for optimizing workflow in an assembly line, the method comprising:
- receiving first motion data from a first image capture device disposed at a first station in the assembly line, wherein the first motion data corresponds with motions executed by a first operator while interacting with an article of manufacture, and wherein the first operator is selected from among one or more operators associated with the first station;
- calculating an error variance for the motions executed by the first operator based on the first motion data;
- identifying, based on the error variance, deviations in the article of manufacture;
- and
- automatically adjusting assembly instructions that are provided to at least one of the one or more operators based on the calculated error variance to generate modified assembly instructions.
A system for optimizing workflow in an assembly line, the system comprising:
- a plurality of image capture devices, wherein each of the image capture devices is disposed at one or more of a plurality of stations in an assembly line;
- and
- an assembly instruction module configured to automatically modify guidance and instructions provided to one or more of the plurality of stations, wherein the assembly instruction module is coupled to the plurality of image capture devices, and wherein the assembly instruction module is configured to perform operations comprising:
- receiving, by the assembly instruction module, first motion data from a first image capture device from among the plurality of image capture devices, and wherein the first image capture device is disposed at a first station in the assembly line, wherein the first motion data corresponds with motions executed by a first operator while interacting with an article of manufacture, and wherein the first operator is selected from among one or more operators associated with the first station;
- calculating an error variance for the motions executed by the first operator based on the first motion data;
- identifying, based on the error variance, deviations in the article of manufacture;
- and
- automatically adjusting assembly instructions that are provided to at least one of the one or more operators based on the calculated error variance to generate modified assembly instructions.
A non-transitory computer-readable media comprising instructions stored thereon which, when executed by one or more processors, are configured to cause the processors to execute instructions comprising:
- receiving first motion data from a first image capture device disposed at a first station in the assembly line, wherein the first motion data corresponds with motions executed by a first operator while interacting with an article of manufacture, and wherein the first operator is selected from among one or more operators associated with the first station;
- calculating an error variance for the motions executed by the first operator based on the first motion data;
- identifying, based on the error variance, deviations in the article of manufacture;
- and
- automatically adjusting assembly instructions that are provided to at least one of the one or more operators based on the calculated error variance to generate modified assembly instructions.
