Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electronic products and relates to a ceramic piece performance processing device, in particular to a high-precision polarization device. Background Art
[0002] Piezoelectric ceramics, as functional materials that convert mechanical and electrical properties into each other, are widely used in various fields such as communications, measurement, biology, and aerospace. Polarization is the process of applying a strong DC electric field or voltage to a piezoelectric ceramic to orient the electric domains in the ceramic along the direction of the electric field. Before the polarization process, the distribution of the spontaneous polarization directions of the electric domains 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 the electric domains is aligned to a certain extent according to the external electric field orientation, so the polarization intensity in the ceramic is no longer zero, and the ceramic exhibits a piezoelectric effect. In order to achieve perfect polarization of piezoelectric ceramics and give full play to their piezoelectric properties, it is necessary to reasonably select the polarization conditions, namely the polarization electric field (polarization voltage per unit length of the sample), polarization temperature, and polarization time.
[0003] However, the existing polarization devices have a single function and poor precision, which reduces the qualified rate of finished products. Therefore, there is a need to provide a high-precision polarization device. Utility Model Content

The fine-tuning probe positioning mechanism is arranged above the constant temperature heating mechanism and can move up and down under the action of the pressure-holding mechanism. 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 includes 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.
[0007] Preferably, the fine-tuning probe positioning mechanism includes a horizontal substrate, an X / Y axis micrometer adjuster is provided on the horizontal substrate, and the conductive probe is provided below the X / Y axis micrometer adjuster.
[0008] Preferably, guide rods are further provided on both sides of the horizontal base plate, and the horizontal base plate is slidably connected to the guide rods and can move up and down along the guide rods under the action of the pressure-maintaining mechanism.

DETAILED DESCRIPTION
[0018] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments described are merely a portion of the embodiments of the present invention, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and in no way limits the present invention, its application, or use. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.
[0019] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.
[0020] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.
[0021] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
[0022] For the purposes of the description, reference can be made to spatially relative terms, such as "on", "above", "over", "top", "bottom", "side", "down", "up", "right", "left", "front", "back", etc. to describe the relative position of one element to another element as illustrated in the figures. It is understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientations depicted in the figures. For example, if a device is inverted, then the element described as "above" or "over" another element would now be positioned "below" or "under" the other element. Thus, the example term "above" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. The terms "first", "second", "third", etc. do not necessarily indicate any ordinal, chronological or other sequence unless expressly stated to do so.
[0023] In addition, it should be noted that the use of "first", "second", etc. words to define parts, only for the convenience of the corresponding parts, as there is no declaration, the above words have no special meaning, therefore can not be understood as the limitation of the scope of protection of the utility model.
