Description
Technical Field
The invention relates to the field of polarization clamps and mechanical manufacturing of piezoelectric materials, in particular to a polarization clamp for a piezoelectric composite film material.
Background
Piezoelectric materials are important materials for converting mechanical energy into electrical energy, and are currently ubiquitous in social production and life. The piezoelectric materials are classified into inorganic piezoelectric materials and organic piezoelectric materials, and the inorganic piezoelectric materials include piezoelectric ceramics and piezoelectric single crystals. The organic piezoelectric material is a kind of organic piezoelectric film represented by polyvinylidene fluoride. The piezoelectric ceramic material is a novel piezoelectric material formed by compounding piezoelectric ceramic and other matrix materials in a certain mode. Compared with inorganic piezoelectric materials, the composite piezoelectric material has the advantages of good flexibility, low density, easy realization of large-area molding, good performance designability, high voltage piezoelectric coefficient and the like. Compared with the organic piezoelectric material, the composite piezoelectric material not only has the advantages of flexibility, designability and the like of the organic piezoelectric material, but also has a higher piezoelectric strain constant than the organic piezoelectric material, so that the piezoelectric composite material can be applied to the fields of water sound, ultrasound, medicine and the like.
Along with the development of piezoelectric materials, a polarization process of the piezoelectric materials is carried out, and the newly prepared piezoelectric materials do not have piezoelectric characteristics and must be polarized through the polarization process. After polarization, the anisotropic multi-domain structure in the piezoelectric material is converted into a single-domain structure, and piezoelectric properties are exhibited.
In the polarization process, the design of the clamp is a critical ring. The clamp ensures the fit between the piezoelectric material and the electrode. If the clamp is designed poorly, the adhesion between the piezoelectric material and the electrode is not tight, which is likely to cause film breakdown, lead to polarization failure, and even lead to polarization electrode revocation. Therefore, the invention provides the polarization clamp for the piezoelectric composite film material, which is specially used for clamping the piezoelectric composite film material with a smaller area, has small volume, can be used in parallel, has adjustable clamping force, and has strong interchangeability, convenient maintenance, convenient manufacture and low cost.
