Abstract: In the analysis of automatic production line, firstly, the PLC control circuit is studied, and the consistency of leakage pattern access and source pattern access between NPN, PNP photoelectric sensors and Mitsubishi FX3U is discussed; then, the application of photoelectric sensor in automatic production line is studied, and the non-contact work piece detection methods of diffuse reflection, mirror reflection and opposite reflection of photoelectric sensor are analyzed; finally, the PLC programming of the automatic production line is studied, and it is concluded that the light receiving opening and shading opening detection modes of the adjustable photoelectric sensor are represented by normally open and normally closed contacts respectively, and the inconsistency between the selected contacts and the detection mode will lead to the program cannot continue to run.
Keywords: photoelectric sensor; automatic production line; detection
