Two kinds of alignment schemes which are suitable for the high-precision automatic docking coupling of optical waveguides are designed, which overcomes the difficulties in the accurate measurement of the micro-deformation signals in the conventional alignment process. Completed the alignment system optical mechatronics, control procedures and interface interface. Single-mode fiber as a standard waveguide end-face coupling automatic alignment test showed that the average coupling loss were 0 .0 75dB (1310nm wavelength) and 0. 062dB (1550nm wavelength), the corresponding standard error of 0 .0 0 99dB and 0. 0 6 6dB, alignment process completed in 2min. The experimental results of single-mode fiber single-mode waveguide single-mode fiber docking coupling show that the average of the end-face coupling loss is respectively 0.14 0dB (1310nm wavelength) and 0.109dB (1550nm wavelength), the standard errors are 0 .0 0 82dB and 0 .0 10 7dB, adjusting the total time does not exceed 8min
