Title:
MOULDING DEVICE FOR SPHERICAL ULTRASONIC TRANSDUCER AND RELATED METHOD
Document Type and Number:
WIPO Patent Application WO/2019/100210
Kind Code:
A1
Abstract:
Disclosed are a moulding device for a spherical ultrasonic transducer and a related method. The moulding device comprises: a supporting component, a moulding component and a compressing component, wherein the supporting component is used for supporting the moulding component; the moulding component comprises a moulding die (23) and a sphere (24), the moulding die (23) being made of an elastic material and having a recessed spherical face (23a) matching the sphere (24); a piezoelectric ceramic material is placed between the recessed spherical face (23a) of the moulding die (23) and the sphere (24); and the compressing component is used for exerting pressure on the moulding component for moulding of the piezoelectric ceramic material, and the supporting component, the moulding component and the compressing component are coaxially provided. The spherical transducer made by the moulding device has a precise radius of curvature, and spherical ultrasonic transducers with different radii of curvature can be made, giving wider universality. By means of the moulding device, the piezoelectric ceramic material is easily moulded, will not easily break, and has good uniformity and consistency. Furthermore, the moulding device is convenient to carry and easy to operate.
