Description

Technical Field

[0002] As is well known, after printing silver paste (silver coating) on ​​the surface of piezoelectric ceramics, polarization treatment is required to achieve the inverse piezoelectric effect. Polarization involves applying a strong DC electric field to the piezoelectric ceramic, causing the electric domains in the ceramic to align along the direction of the electric field; this is also known as artificial polarization or single-domain treatment. In existing technologies, piezoelectric ceramic sheets generally use silicone oil or hydraulic oil as the insulating medium, and polarization is performed under specific polarization electric field, temperature, and time conditions. Existing polarization devices are mainly used for polarizing piezoelectric ceramic sheets; there are currently no polarization devices specifically designed for piezoelectric ceramic tubes.

[0013] like Figure 1 , Figure 2As shown, the piezoelectric ceramic tube polarization device includes: an insulating substrate 1, with a support rod 2 at each of the four corners of the insulating substrate 1, supporting the insulating substrate 1; eight clamping components 3 arranged in two rows along the front-back direction on the front of the insulating substrate 1; each clamping component 3 consisting of an elastic clamp 4 and a columnar clamp 5, which can clamp the piezoelectric ceramic tube from the left and right sides respectively; the elastic clamps 4 and columnar clamps 5 in each row are aligned front-back; a first copper strip 6 is provided on the back of the insulating substrate 1 below each row of elastic clamps 4; a second copper strip 7 is provided on the back of the insulating substrate 1 below each row of columnar clamps 5; a screw is passed through the base of each elastic clamp 4, and the screw passes through the insulating substrate 1 and the first copper strip 6 below the elastic clamp 4 before being tightened with a nut, so that each elastic clamp 4 can be fixed to the insulating substrate 1. It can also be connected to the corresponding first copper strip 6. Each columnar clamp 5 has a stud section at the bottom. The stud section passes through the insulating substrate 1 and the second copper strip 7 below the columnar clamp 5 and is then fixed by two nuts. This allows each columnar clamp 5 to be fixed on the insulating substrate 1 and to be connected to the corresponding second copper strip 7. One end of the two first copper strips 6 is connected to the first overlapping copper strip 8, and one end of the two second copper strips 7 is connected to the second overlapping copper strip 9. The first overlapping copper strip 8 and the second overlapping copper strip 9 are located at both ends of the insulating substrate 1. The connection between the first overlapping copper strip 8 and the two first copper strips 6 is fixed by the first conductive screw 10 and the nut passing through the insulating substrate 1. The connection between the second overlapping copper strip 9 and the two second copper strips 7 is fixed by the second conductive screw 11 and the nut passing through the insulating substrate 1. Two electrode posts 12 are also provided on the front side of the insulating substrate 1. The two electrode posts 12 are connected to the first conductive screw 10 and the second conductive screw 11, respectively.

[0014] An oil passage hole 13 is provided on the insulating substrate 1 below the two rows of clamping components 3. The oil passage hole 13 is provided so that the tooling can be quickly immersed in the oil when it is placed in the oil, thereby improving work efficiency.

[0015] The elastic chuck 4 is a Z-shaped spring piece. The Z-shape can make the chuck more elastic. The top of the elastic chuck 4 is also provided with an arc-shaped boss 14. The arc surface of the arc-shaped boss 14 clamps the piezoelectric ceramic tube. The arc-shaped boss 14 is less likely to scratch the silver paste surface of the piezoelectric ceramic.

[0018] During operation, the piezoelectric ceramic tube 16 is fitted onto the cylindrical clamp 5, and then the elastic clamp 4 and the cylindrical clamp 5 clamp the piezoelectric ceramic tube. The fixture is then immersed in insulating oil. Next, the positive and negative terminals of the power supply are connected to the two electrode posts 12 via electrical clamps, respectively. Under the conductivity of the copper strip, the elastic clamp 4 and the cylindrical clamp 5 carry positive and negative charges, respectively, polarizing the piezoelectric ceramic tube. The cylindrical clamp 5 is more suitable for clamping piezoelectric ceramic tubes; even small-diameter piezoelectric ceramic tubes can be clamped between the elastic clamp 4 and the cylindrical clamp 5, making the piezoelectric ceramic tube polarization fixture more suitable for polarizing piezoelectric ceramic tubes.
