Description

Technical Field

[0001] This utility model relates to the field of piezoelectric ceramic material polarization technology, and in particular to a polarization fixture applicable to piezoelectric ceramic products of various sizes. Background Technology

[0002] In this era of rapid development in electronic products, functional piezoelectric ceramics are ubiquitous in our daily lives. Piezoelectric ceramics are functional ceramic materials capable of converting mechanical energy into electrical energy. Due to their excellent mechanical properties and stable piezoelectric properties, and as an important force, heat, electricity, and photosensitive material, they are widely used in high-tech fields such as mobile communications, satellite broadcasting, electronic equipment, instruments, biology, and aerospace. With the rapid development of science and technology, the performance requirements for piezoelectric ceramic materials are becoming increasingly stringent, especially in the polarization process, where it is necessary to ensure the quality and production efficiency of piezoelectric ceramic products. However, traditional polarization fixtures often only polarize piezoelectric ceramics of specific sizes, failing to meet the needs of products of various sizes, which greatly limits production efficiency and flexibility. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a polarization fixture applicable to piezoelectric ceramic products of various sizes, which can be easily adjusted to adapt to piezoelectric ceramic products of different sizes, thereby improving production efficiency.

[0004] To achieve the above objectives, this utility model proposes a polarization fixture applicable to piezoelectric ceramic products of various sizes, including a PCB board, a polytetrafluoroethylene (PTFE) block, and a copper block. The PCB board is provided with a positive copper post and a negative copper post. The PTFE block and the copper block are symmetrically arranged on the PCB board, with the copper block fixedly connected to the PCB board and the PTFE block slidably connected to the PCB board. A row of pins is fixedly fixed along the length of the PTFE block near the copper block, with the pins extending forward and backward and the front ends of each pin being flush. The row of pins is arranged diagonally from the upper right corner to the lower left corner of the PTFE block. Each pin is connected to the positive copper post through an electronic wire, and the copper block is connected to the negative copper post through an electronic wire.

[0005] In the above scheme: the PCB board is provided with front and rear extending guide grooves, and the polytetrafluoroethylene block is slidably limited in the guide grooves by bolts and nuts, thereby realizing the sliding connection with the PCB board. The structure is simple and easy to process. The guide grooves can be set as two or three parallel ones.

[0006] In the above scheme: the polytetrafluoroethylene block is provided with through holes corresponding to each ejector pin, and the ejector pins are fixedly installed in each through hole by sealant. The end of the ejector pin can protrude through the through hole to facilitate the subsequent connection of electronic wires.

[0007] In the above scheme: each ejector pin is equipped with a fuse, which is fixed to the PCB board by a fuse clip. The end of each ejector pin is connected to the corresponding fuse via a spiral electronic wire. The fuse is connected to the positive copper pillar via a high-temperature resistant electronic wire, and the copper block is also connected to the negative copper pillar via a high-temperature resistant electronic wire. The spiral electronic wire design allows for longer wiring lengths within a limited space. This electronic wire easily follows the movement of the PTFE block, avoiding restrictions on the movement of the PTFE block.

[0008] In the above scheme: a total of 18 to 20 ejector pins are arranged on the polytetrafluoroethylene block, with each ejector pin evenly spaced and sufficient in number, so that ejector pins are provided at all heights of the polytetrafluoroethylene block, which facilitates the fixing and positive polarization of products of different thicknesses.

[0009] In the above scheme: the PCB board is provided with four support bolts, which are located at the four bottom corners of the PCB board respectively. The support bolts play a supporting role and isolate the polarization fixture from the ground or table.

[0010] The beneficial effects of this utility model are:

[0011] 1. The PTFE block can slide towards the copper block, thereby adjusting the distance between the PTFE block and the copper block to accommodate piezoelectric ceramic products of different sizes; 2. The ejector pins are arranged diagonally from the upper right corner to the lower left corner of the PTFE block, enabling the fixing and positive polarization of products of different thicknesses. In summary, this invention is applicable to piezoelectric ceramic products of various sizes, greatly improving production efficiency and flexibility, reducing polarization costs, and is simple in structure and easy to operate.
