The six-axis robot is mainly used for the transfer of lightweight electrolyte loading sampling cups, sample pressing steel rings, and raw aluminum, while the truss manipulator is mainly used for the transfer of heavier vibration grinding sample boxes, thus realizing the automation of the material transfer process.

[0008] Furthermore, the PLC unit control system uses a large PLC controller as its hardware basis and software programming as its means to perform sequential and logical control over the various components of the fully automatic sample preparation and testing equipment, monitor and alarm abnormal conditions of the equipment, and communicate with the logistics system and the industrial computer master control system to achieve equipment action linkage and data transmission; the industrial computer master control system automatically identifies product identity information, tracks product processes, and ultimately makes product identity and test data correspond one-to-one, automatically records and stores test data, and performs production quantity statistics.

[0009] Furthermore, the industrial computer master control system sends instructions to the PLC unit control system to control the PLC to execute corresponding actions in sequence and display the status of the PLC executing the actions; the PLC unit control system issues control instructions to execute the required actions on each sub-functional module, and after the actions are completed, feedback signals are sent to the PLC unit control system; the PLC unit control system interacts with the six-axis robot control system, the truss manipulator control system, and the component detection system to control the start and stop of each subsystem; the component detection system (85) transmits the detection data to the industrial computer master control system (81), and the industrial computer master control system (81) stores, analyzes and displays the data.

[0010] The present invention has the following technical effects:

[0011] The hardware system of the present invention is designed with miniaturized non-standard equipment and is highly integrated. All equipment occupies an area of ​​2.5 meters x 3 meters. Compared with the existing sample preparation and testing methods, the floor space is reduced by eight to ten times, solving the problem of scattered equipment space layout and large floor space. This patent uses a robot combined with a truss manipulator for transportation. The transportation process does not require human intervention. At the same time, the processing equipment is designed and modified for automation. Compared with the existing sample preparation and testing methods, the number of operators is reduced from 7 to 1, solving the problem of high human resource consumption.

[0012] Therefore, the present invention is used for sample preparation and detection of electrolyte and raw aluminum in the electrolytic aluminum industry, and has the advantages of small footprint, low labor cost, high detection efficiency, good detection quality, significant production benefits, and high degree of automation.
