Embodiment 1

[0033] see figure 1 , is a flow chart of the method for manufacturing the piezoelectric ceramic transducer provided in this embodiment. It includes steps S1-S6:

[0034] S1: Slicing and segmenting the three-dimensional structure of the high-frequency ultrasonic transducer to obtain a series of two-dimensional cross-sections of the high-frequency ultrasonic transducer.

[0035] Specifically, in this step, computer software such as AutoCAD is used to slice and segment the three-dimensional structure of the high-frequency ultrasonic transducer to obtain a series of two-dimensional cross-sections of the high-frequency ultrasonic transducer.

[0036] S2: The high-frequency ultrasonic transducer includes a plurality of components; select one of the components of the high-frequency ultrasonic transducer, and prepare a printing paste for the selected component.

[0037] This step is used to prepare the printing paste, adding the solid powder into the photocuring agent solution to pr...

Abstract

The invention discloses a method of manufacturing a piezoelectric ultrasonic transducer. The method comprises the following steps: S1, segmenting a slice of a three-dimensional structure of a high frequency ultrasonic transducer to obtain a series of two-dimensional sections of the high frequency ultrasonic transducer; S2, as the high frequency ultrasonic transducer comprises a plurality of parts,selecting one of the parts of the high frequency ultrasonic transducer to prepare printing slurry of the selected part; S3, irradiating the part with a curing light source, projecting a mask image ofthe two-dimensional section of the selected part to the surface of the printing slurry, and curing and forming the selected part to obtain a biscuit of the selected part; S4, drying and degreasing the biscuit of the selected part to obtain a blank of the selected part; and S5, repeating S2-S5, and forming a next part of the high frequency ultrasonic transducer till every part of the high frequency ultrasonic transducer is formed to obtain a whole blank of the high frequency ultrasonic transducer. The method provided by the invention meets a high precision demand in manufacturing the ultrasonic transducer, and the work efficiency is improved greatly.

Description

technical field [0001] The invention relates to a method of manufacturing a piezoelectric ultrasonic transducer. Background technique [0002] Piezoelectric ceramics are the most common materials used in the manufacture of ultrasonic transducers. The traditional piezoelectric ceramic materials are manufactured in the form of subtractive manufacturing, which has the problems of long investment time and complicated procedures. However, piezoelectric ceramic materials have been widely used now, and the traditional manufacturing mode has been far away. far from meeting the needs of society. With the continuous development of science and technology, the precision and complexity of piezoelectric ceramic materials produced by traditional techniques also have great limitations. [0003] With the continuous development of 3D technology, 3D technology has also been used in the manufacturing process of ultrasonic transducers, and the complexity and precision of the manufactured produ...
