Piezoelectric ceramic piece positive and negative electrode electrical connection device

Abstract

A piezoelectric ceramic piece positive and negative electrode electrical connection device comprises a silver slurry tank, conductive silver slurry, a cylindrical rod, bearings, a piezoelectric ceramic piece, and electrodes. The silver slurry tank contains the conductive silver slurry. The bearings are mounted at one end of the silver slurry tank. One end of the cylindrical rod passes through one end of the silver slurry tank, and the other end of the cylindrical rod is fixed to the bearings at the other end of the silver slurry tank. The piezoelectric ceramic piece is arranged on the cylindrical rod, and the circular surface of the piezoelectric ceramic piece is perpendicular to the length direction of the cylindrical rod. The electrodes are arranged on the piezoelectric ceramic piece. By using the device, the width and depth of electrode connection can be controlled, the appearance consistency of connection is good, the electrical reliability of connection is high, and the consumption of silver slurry is reduced by about 2 / 3.

Description

technical field [0001] The invention relates to the technical field of piezoelectric ceramics, in particular to an electrical connection device for front and back electrodes of a piezoelectric ceramic sheet. Background technique [0002] At present, the application fields of piezoelectric ceramic sheets are becoming wider and wider, especially in piezoelectric ultrasonic transducers. Such as ultrasonic atomization tablets, ultrasonic fetal heart tablets, ultrasonic cosmetic tablets, etc., most of these products require the positive and negative electrodes of the piezoelectric ceramic sheet to be set on the same surface of the ceramic for electrical extraction. The traditional method is to level the silver paste on the plastic cloth and then press the piezoelectric ceramic sheet into the silver paste. This method has poor appearance consistency and serious waste of silver paste. Another method is to stick the silver paste with a brush and paint it on the area that needs elec...

Problems solved by technology

The traditional method is to level the silver paste on the plastic cloth and press the piezoelectric ceramic sheet into the silver paste. This method has poor appearance consistency and serious waste of silver paste.

Another method is to stick the silver paste with a brush and paint it on the area that needs electrical connection. This method does not meet the requirements for electrical connection reliability, and the appearance consistency is very poor.
