Beschreibung
Zusammenfassung:	An optical positioning code disk, device and method for a microfluidic chip are provided. A cross section of an outer contour of the code disk is circular. N light transmissive openings are arranged uniformly around the code disk. The device includes: the code disk, a positioning pin, a rotating shaft, a motor, an internal photoelectric switch and an external photoelectric switch. A positioning surface is provided on the rotating shaft. The motor is fixedly connected with an end of the rotating shaft, and the other end of the rotating shaft passes through a center of the cross section of the code disk. The internal and external photoelectric switches are configured to identify the light transmissive openings on the code disk.
