The invention provides a manufacturing method of a two-dimensional array energy converter and the two-dimensional array energy converter and relates to the technical field of two-dimensional array energy converters. The method comprises the following steps: printing a first matching layer and a second matching layer through a 3D (Three Dimensional) printing technology; adhering the first matching layer to a ground electrode face of a piezoelectric wafer, and adhering the second matching layer to the first matching layer, so as to form a first integrated part through the piezoelectric wafer, the first matching layer and the second matching layer; cutting the first integrated part from a side face to form two-dimensional arrays which are orthogonal vertically and horizontally; molding the two-dimensional arrays which are orthogonal vertically and horizontally into a plane on a molding die; according to the two-dimensional arrays which are orthogonal vertically and horizontally and are molded into the plane, generating a public electrode lead wire and a signal transmission channel, so as to from a second integrated part; by virtue of the 3D printing technology, printing the outer part of the second integrated part into a back lining through adopting a back lining filling die; and by virtue of the 3D printing technology, printing an acoustic lens on the outer side of a part cured and molded by the back lining through adopting an acoustic lens filling die.
Description
technical field [0001] The invention relates to the technical field of two-dimensional array transducers, and in particular, to a manufacturing method of a two-dimensional array transducer and a two-dimensional array transducer. Background technique [0002] At present, ultrasonic diagnostic devices are widely used in the medical field. By transmitting ultrasonic waves into the body of the subject and performing in-vivo inspections according to the received echoes, human diseases can be found by measuring the physiological or tissue structure and morphology. At present, three-dimensional ultrasound imaging is one of the important directions of the development of ultrasound medicine. In three-dimensional ultrasound imaging, three-dimensional image acquisition generally needs to be realized by two-dimensional array transducers. [0003] At present, two-dimensional array transducers can be divided into rectangular arrays and circular arrays according to the arrangement of arra...
