Abstract: Integrated circuit (IC) equipment research and development occupies an important position in the machinery manufacturing industry, which is an important factor to improve the technical level and international competitiveness. In the context of university-industry collaborative education, this paper combines IC equipment to design an IC precise sorting and positioning experimental teaching system with virtual-reality integration. This system uses the virtual model to debug and optimise the mechanical design and control program, and combines the experimental equipment to verify the program. Also, this system integrates multidisciplinary knowledge of optoelectronic sensing, electromechanical transmission and circuit design, aiming at realising cross-curricular experimental teaching of mechanical majors. The system supports experiments such as electromechanical transmission control, virtual programme debugging, programmable controller programming and IC precise sorting and positioning. Based on the design of IC sorter, it introduces real-world industrial application scenarios into experimental teaching. The teaching method of virtual-real fusion effectively meets the experimental demand of PLC programme debugging of a large number of students, and provides an efficient and flexible solution for experimental teaching. Experimental data show that the system achieves a positioning repeatability of ±0.15 mm, a communication delay under 5 ms, and a synchronous error between virtual and real movements under 30 ms, meeting the requirements of teaching experiments.
