Due to the fact that both the positive pole and the negative pole of the piezoelectric ceramic piece set are made up of the components of the integrated structures, assembling efficiency is improved and the rejection rate and the defective rate of products are reduced.
Description
Technical field
The present invention relates to the transducer that ultrasonic scaling machine or piezosurgery osteotomy machine use.
Background technology
Ultrasonic transducer is the critical piece of ultrasonic medical equipments such as ultrasonic scaling machine, osteotome machine, be installed in the inside of handle, usually be divided into upper, middle and lower three parts, it specifically is the luffing bar on top, the piezoelectric ceramic piece group at middle part and the mobile jib of bottom, the effect of piezoelectric ceramic piece group is the mechanical energy that converts electrical energy into dither.
Piezoelectric ceramic wafer in the piezoelectric ceramic piece group in the ultrasonic transducer that uses in existing ultrasonic scaling machine, the osteotome machine has four usually, the end face of the identical polar of adjacent two piezoelectric ceramic wafers abuts in together during placement, be equipped with electrode slice between adjacent two piezoelectric ceramic wafers, each electrode slice is copper sheet independently, and electrode slice is positive and negative interval and places.When the assembling transducer, realize the dual mode that is electrically connected with of piezoelectric ceramic piece group: (1) welds together power line and an anode electrode sheet (or negative electricity pole piece) earlier, and then other anode electrode sheet (or negative electricity pole piece) is welded on this power line; (2) earlier all anode electrode sheets (or negative electricity pole piece) are welded on the lead, and then this lead is connected with power line.But no matter be to adopt any mode, all have the many deficiencies of pad, and how pad not only can reduce efficiency of assembling, improves production cost, the more important thing is because needs repeat multiple welding to cause useless, the defect rate of transducer to increase.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of assemble simple and the high transducer of efficient.
Transducer of the present invention, mainly by the luffing bar on top, the piezoelectric ceramic piece group at middle part and the mobile jib of bottom are formed, described piezoelectric ceramic piece group is made up of four piezoelectric ceramic wafers at least, unlike the prior art be:
The parts of the parts of described formation piezoelectric ceramic piece group positive pole and formation piezoelectric ceramic piece group negative pole all are structure as a whole, the parts that wherein constitute piezoelectric ceramic piece group positive pole comprise a sheet metal, and setting at least two electrode slices thereon, the distance on the described sheet metal between adjacent two electrode slices is for placing two piezoelectric ceramic wafers with the form that stacks; The parts of described formation piezoelectric ceramic piece group negative pole are identical with the modular construction that constitutes piezoelectric ceramic piece group positive pole;
Electrode slice in the parts of described formation piezoelectric ceramic piece group negative pole is placed at interval with the electrode slice in the parts that constitute piezoelectric ceramic piece group positive pole.
In the technique scheme, each electrode slice that is arranged on the sheet metal is preferably vertical with this sheet metal.
In the technique scheme, when the piezoelectric ceramic piece group is made up of six piezoelectric ceramic wafers, should be provided with three electrode slices on the sheet metal.
In the technique scheme, described sheet metal and electrode slice are copper sheet.
In the transducer of the present invention, the parts that constitute piezoelectric ceramic piece group positive pole and being connected of power line can be that sheet metal or the electrode slice during it is formed is connected with power line, and the parts of formation piezoelectric ceramic piece group negative pole are as the same with being connected of power line.
Compared with prior art, transducer of the present invention, adopt the parts of integrative-structure to constitute piezoelectric ceramic piece group positive pole and negative pole, only there is the pad between parts and the power line, significantly reduced the pad in the assembling process, improve efficiency of assembling on the one hand, reduced production cost; On the other hand because not needing the repetition multiple welding, thereby effectively reduce useless, the defect rate of product.
