Description

Technical Field

[0001] The invention belongs to the technical field of electronic products and relates to a ceramic sheet performance processing device, in particular to a high-precision polarization device. Background Art

[0002] As a functional material with mutual conversion between mechanical and electrical properties, piezoelectric ceramics are widely used in various fields such as communication, measurement, biology, and aerospace. The so-called polarization is to apply a strong DC electric field or voltage to the piezoelectric ceramic so that the electric domains in the ceramic are oriented along the direction of the electric field. Before the polarization process, the distribution of the spontaneous polarization direction of each electric domain in the ceramic is chaotic, so the polarization intensity in the ceramic is zero, and the ceramic has no piezoelectric effect. After the polarization process, the spontaneous polarization of each electric domain is arranged according to the external electric field orientation to a certain extent, so the polarization intensity in the ceramic is no longer zero, and the ceramic has a piezoelectric effect. In order to make the piezoelectric ceramics perfectly polarized and give full play to their piezoelectric properties, it is necessary to reasonably select the polarization conditions, that is, the polarization electric field (polarization voltage per unit length of the sample), polarization temperature and polarization time.

[0003] However, the existing polarization devices currently have single functions and poor precision, which results in a reduced qualified rate of finished products. Therefore, a high-precision polarization device needs to be provided. Summary of the invention

The fine-tuning probe positioning mechanism is also provided with an X / Y-axis micrometer adjuster for adjusting the conductive probe.

[0006] Preferably, the pressure-maintaining mechanism comprises a vertically arranged column, a cylinder is arranged on the column, and an output end of the cylinder is connected to a fine-tuning probe positioning mechanism.
