Abstract

Taking the semi-finished product inspection and laser unit as the research object, this study designs its digital twin system based on the Tecnomatix platform. Through mapping and modeling, a 3D twin model library of the unit is constructed, and its kinematic mechanism and PLC signal mapping are defined. With the help of TIA, PS, and S7-PLCSIM Advanced, a virtual commissioning environment is built to complete the modular design of the PLC program and the full-process joint commissioning of the semi-finished product inspection and laser unit. This system can verify the production line logic in advance, avoid equipment interference, simplify the programming process, shorten the commissioning cycle, and reduce costs. The research shows that the designed digital twin system can effectively support the stable operation of the Kongming Lock demonstration line, and provide a technical reference for the digital transformation of manufacturing enterprises and the upgrading of traditional intelligent manufacturing.
