Silver coating device for piezoelectric ceramic piece

Abstract

The invention discloses a silver coating device for a piezoelectric ceramic piece, and the device comprises a bottom plate and a placement plate; two symmetrically-distributed T-shaped sliding grooves are formed in the outer wall of the top of the bottom plate, sliding blocks are slidably connected to the inner walls of the two T-shaped sliding grooves, supporting columns are fixed to the outer walls of the tops of the two sliding blocks, and trapezoidal connecting blocks are fixed to the top ends of the two supporting columns; and the same material collecting frame is fixed to the outer walls of the tops of the two trapezoidal connecting blocks. According to the device, the placement plate is arranged, a piezoelectric ceramic piece can be placed on the placement plate, then iron blocks on the two limiting rods make contact with annular magnets on the bottom plate so that the piezoelectric ceramic piece can be clamped, and the placing plates of different specifications and sizes and pressing plates, sealing gaskets, the limiting rods and the iron blocks matched with the placement plate can be arranged according to needs; and then, a thread groove matched with the external thread block only needs to be formed in the bottom of the corresponding placement plate, replacement is convenient, and the clamping device can be suitable for clamping piezoelectric ceramic pieces of different specifications.

Description

technical field [0001] The invention relates to the technical field of piezoelectric ceramic sheets, in particular to a silver coating device for piezoelectric ceramic sheets. Background technique [0002] Piezoelectric ceramic chip is a kind of electronic sounding element. A piezoelectric ceramic dielectric material is placed between two copper circular electrodes. When an AC audio signal is connected to the two electrodes, the piezoelectric chip will Vibration produces corresponding sound. At present, silver-coated devices on piezoelectric ceramic sheets cannot adapt to piezoelectric ceramic sheets of different specifications and sizes, and cannot meet different work requirements. Contents of the invention [0003] The object of the present invention is to propose a silver-coating device for piezoelectric ceramic sheets in order to solve the shortcomings in the prior art. [0004] In order to achieve the above object, the present invention adopts the following technical...
