With regard to low level of automation in pulse-echo measurement of medical ultrasonic transducers and the influence of subjective judgment on the test results, an automatic pulse-echo measurement system of ultrasonic transducers has been designed based on an industrial robot. Design for the pulse-echo measurement system was explained in detail. The key to the construction of the measurement system - the realization of automatic alignment function is compared and analyzed. A complete setting of parameters, automatic alignment function, and an echo acquisition and processing program are developed in the Matlab environment. The automatic alignment algorithm is described in detail. The test results show that the system has reached the design target, the coefficient of variable of sensitivity measurement is less than 0.5%, and can meet the testing needs of daily work. The work in this paper has laid a good foundation for the intelligent manufacturing of the whole process of medical ultrasonic transducer R&D (Research & Design) and production.
