Abstract

The invention provides a diagnostic device and a machine learning device. The diagnostic device is a device for estimating the tension of a belt of an industrial machine for transmitting power, and is provided with a control unit configured to control a diagnostic operation in which the belt is driven, a data acquisition unit configured to acquire at least feedback data at the time of the diagnostic operation, a preprocessing unit configured to analyze frequency-gain characteristics of the feedback data and create, as input data, a range including a resonant frequency and an anti-resonant frequency in the characteristics, and a machine learning device configured to perform processing related to machine learning, based on the data created by the preprocessing unit. The diagnostic device supports inference or abnormality detection of the value of the belt tension.

Description

technical field [0001] The present invention relates to a diagnostic device and a machine learning device, and more particularly to a diagnostic device and a machine learning device for diagnosing the tension of a conveyor belt that transmits power. Background technique [0002] Introduce a diagnostic device that diagnoses the operating status of industrial machinery such as robots, machine tools, and injection molding machines installed on production lines at manufacturing sites such as factories. The diagnostic device monitors the operation status of industrial machinery so that the production line does not stop, and it can recover quickly when the production line stops. [0003] An industrial machine has a mechanism for transmitting the rotational power of a motor to a shaft via a power transmission unit such as a belt. Whether the tension of the conveyor belt used as the power transmission part is too weak or too strong, the service life will be shortened. In addition,...
