Rare earth metal block automatic detection and sorting control system and method based on industrial Internet of Things

The invention discloses a rare earth metal block automatic detection and sorting control system and method based on the industrial Internet of Things. The system comprises a buffer feeding conveying device, a transfer device, a detection device, a weighing device, a marking device, a sorting output device, and a control system. The sorting output device is controlled to classify the current to-be-processed rare earth metal blocks according to the detection result; and the transfer device is controlled to transfer the rare earth metal blocks on the buffer feeding conveying device to the detection device, the transfer device is controlled to transfer the inspected rare earth metal blocks to the weighing device and the marking device, and the transfer device is controlled to transfer the weighed and marked rare earth metal blocks to the sorting output device. Control and remote monitoring of a production line are achieved through the Internet of Things platform, and automatic detection, sorting, weighing and cod
