| With the development of economy and technology, the enterprises of metallurgical industry transfer and upgrade their structure of automation continuously. Currently, most of the domestic metallurgical industry workers are in enterprises poor working environment and efficiency is low. As a result, robot automation came into being. Use of robot technology, we solve the problem that is how to auto blow slag in the casting of aluminum production line.In the paper, the control system based on "PLC(programmable logical control) + frequency conversion device + AC Asynchronous motor " was studied. In the first, the situation and development trend of aluminum casting manipulator the composition were introduced. Then the casting of aluminum production line and the basic profiles were introduced, through the analysis of the basic profile of the aluminum casting of automatic production lines, we know that the functional requirements and action processes. The AUTO CAD and 3-D CATIA design software were used to complete the parts of the auto blowing slag robot device design. The control system of the auto blowing slag robot device uses a Siemens S7-200 PLC as controller, including the frequency conversion device, Fujitsu FRN1.5C1S-4C1. Finally, to know the control flow analysis of the auto-blow slag robot device, we completed the PLC hardware and the hardware wiring.At present, the auto blowing slag device has been in normally trouble-free operation in the relevant aluminum casting manufacturing enterprises. The Control System based on "PLC + frequency conversion device + AC Asynchronous motor" is low-cost, high-performance, reliability. |
