Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] see figure 1 , figure 2 and image 3 , the present invention is realized in the following manner:

[0024] The method of continuous polarization of chip piezoelectric transformer is carried out in the following steps:

[0025] 1). Directly put the piezoelectric ceramic transformer into the polarization car correctly according to its electrode end, and the hydraulic propulsion system pushes the polarization car into the continuous heating furnace at a certain speed according to the set procedure, and uses air as the medium for polarization ;

[0026] 2). The maximum zone temperature of the continuous heating furnace should be controlled to be 20°C to 30°C above the Curie point temperature of the polarized material;

[0027] a. It takes 5 minutes from normal temperature zone to 150℃ zone;

[0028] b. It takes 17 minutes from the 150°C area to the ...

Abstract

The present inventino has opened a continuous polarization unit of lamellar piezoelectric ceramic transformer (including single and multi sheet transformer) tothe public, which voltage control system, teperature control system, oil-pressure propulsion system, continuous heating furnace and polarization vechile for setting guarding tools are included in the unit. It can polarize piezoelectric end and electricity generating end of lamellar piezoelectric ceramic transformer simultaneously by using air as a media and it also can be used to polarize some other piezoelectric products produced by piezoelectric material as a raw material such as piezoelectric ceramic filter, piezoelectric hummer and etc..

Description

[0001] 1. Field [0002] The invention relates to a polarization method and a polarization control device for piezoelectric ceramic materials. It is not only used for the polarization of piezoelectric ceramic transformers, but also suitable for the polarization of other products made of piezoelectric ceramic materials. It particularly relates to a chip A continuous polarization method and device for piezoelectric transformers. 2. Background technology [0003] Polarization is an important process stage of the piezoelectric ceramic transformer. The sintered piezoelectric ceramic transformer generally does not show piezoelectric performance to the outside because the polarization intensity of the micro-domains in the body is chaotic and the probability along all directions is equal. The most effective way to obtain the piezoelectric characteristics of the piezoelectric ceramic transformer is electric polarization. The so-called electric polarization is to apply a certain DC volt...
