Description

Technical Field

[0001] The present invention relates to a piezoelectric material clamping device, and in particular to a piezoelectric material polarization clamping device and a use method thereof. Background Art

[0002] Piezoelectric materials are crystalline materials that will generate voltage between their two end faces when subjected to pressure. Piezoelectric materials that will generate voltage between their two end faces when subjected to pressure. In 1880, French physicists P. Curie and J. Curie discovered that placing a heavy object on a quartz crystal would generate charges on certain surfaces of the crystal, and the amount of charge was proportional to the pressure. This phenomenon is called the piezoelectric effect. Immediately afterwards, the Curie brothers discovered the inverse piezoelectric effect, that is, piezoelectric bodies will deform under the action of an external electric field. The mechanism of the piezoelectric effect is that piezoelectric crystals have low symmetry. When deformed by external forces, the relative displacement of positive and negative ions in the unit cell causes the centers of positive and negative charges to no longer coincide, resulting in macroscopic polarization of the crystal. The surface charge density of the crystal surface is equal to the projection of the polarization intensity on the surface normal, so when the piezoelectric material is deformed by pressure, charges of opposite signs will appear on the two end faces. Conversely, when a piezoelectric material is polarized in an electric field, the displacement of the charge center will cause the material to deform.

[0003] Piezoelectric ceramics are information functional ceramic materials that can convert mechanical energy and electrical energy into each other - piezoelectric effect. In addition to piezoelectricity, piezoelectric ceramics also have dielectric properties and elasticity, etc., and have been widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors, etc. Piezoelectric ceramics use the fact that under the action of mechanical stress, the internal positive and negative charge centers are relatively displaced and polarized, resulting in the appearance of bound charges of opposite signs on the surfaces of both ends of the material, i.e., piezoelectric effect, and are made. Piezoelectric ceramics have sensitive characteristics. They are mainly used to manufacture ultrasonic transducers, hydroacoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high-voltage generators, infrared detectors, surface acoustic wave devices, electro-optical devices, ignition and detonation devices, and piezoelectric gyroscopes. In addition to being used in high-tech fields, it is more for people in daily life and strives to create a better life for people. Before using piezoelectric ceramics, they need to be polarized to improve their performance. When polarizing piezoelectric ceramics, they need to be clamped and moved using a clamping device, so as to facilitate industrial production.

[0004] At present, there are still some defects and shortcomings in the use of the clamping device. The specific areas that need to be improved are as follows:

[0005] 1. The existing clamping device does not have the functions of automatic separation clamping and mobile transmission, which reduces its automation level and reduces the efficiency of industrial production of piezoelectric ceramic polarization processing;

[0006] 2. The existing clamping device does not have the function of pushing or pulling the piezoelectric ceramics, thus affecting the subsequent automatic clamping operation;

[0007] 3. The existing clamping device does not have the function of automatically pushing and clamping piezoelectric ceramics of different sizes, which makes the device single-function and limited in use;

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention provides a rotating member, a dial member, a linkage member, a corner member and a clamping member, so that the clamping member can clamp and fix the piezoelectric ceramic pushed by the dial member, and then rely on the corner member and the rotating member to rotate, transfer and place with the polarization equipment. In this way, the device can have automatic clamping and transmission for polarization treatment of piezoelectric ceramics, thereby improving its automation level and facilitating the efficiency of polarization treatment for industrial production of piezoelectric ceramics.

[0031] 2. The present invention provides a rotating part, a track part and a dial part, so that the dial part and the track part can automatically push and pull multiple piezoelectric ceramics, thereby automatically pushing and moving multiple piezoelectric ceramics, thereby facilitating a single clamping protrusion with the self-clamping part, which is beneficial to the subsequent clamping operation.

[0032] 3. The present invention sets a track member, a self-clamping member and a dial member. By adjusting the track member, the piezoelectric ceramics between the two baffle plates can be bounced by the rotation of the dial member, so that the piezoelectric ceramics are forced to move automatically and clamp between the two clamping plates on the self-clamping member and slide out. In this way, piezoelectric ceramics of different sizes can be automatically clamped, slid out and clamped, thereby improving the functional diversity of the device and the wide application of piezoelectric ceramic compression.

[0033] 4. The present invention provides linkage parts, corner parts and clamping parts, so that the corner parts can adjust the lifting and rotation of the clamping parts, thereby facilitating the clamping of the piezoelectric ceramics on the clamping parts, and then rotating them to the polarization equipment for polarization treatment by means of the rotating parts. In this way, the device will not affect the transmission effect of the piezoelectric ceramics for polarization treatment.

[0034] 5. The present invention provides linkage parts and clamping parts, so that the clamping parts can clamp the piezoelectric ceramics between the two clamping plates, while the two clamping plates on the clamping parts clamp and move together, so that it is convenient to clamp and move piezoelectric ceramics of different sizes, so that the piezoelectric ceramics can be separated from the clamping plates for transfer and transmission. This will not affect the clamping operation, but also improve the effect of automatically clamping piezoelectric ceramics of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS
