Description
Technical field
The invention mainly relates to a kind of new transducer architecture, the especially ultrasonic transducer of piezoelectric chip form.
Background technology
Ultrasonic transducer is most crucial part in ultrasonic equipment, is that high-frequency electrical energy is converted to mechanical energy by one kind
The energy conversion device of (i.e. ultrasonic wave), generally there is two kinds of magnetostrictive transducer and piezo crystals chip transducer.Magnetostriction
The electro-acoustic conversion efficiency of transducer can slowly lose electroacoustic transfer capability than relatively low after a certain period of use time, so using
It is less.
Current comparative maturity is reliably piezoelectric transducer, the main piezo-electric effect using piezoelectric ceramic piece, and its is general
Structure back shroud, potsherd, electrode slice, front shroud, prestressing force screw rod as shown in figure 1, be made up of.Can be divided into according to shape
Several shapes such as cap-type, middle folder aluminium flake after cylindricality, trumpet type, steel.It is mainly used in ultra-sonic welded, ultrasonic wave cleaning, surpasses
The fields such as sound wave extracting and emulsifying.
The transducer of the structure type is primarily present following 2 points of deficiencies：
First, the transducer electrode piece of steel construction is general to be made by scale copper or nickel sheet, and because existing piezoelectric type is changed
Energy device crystalline substance heap is not distributed on the nodal section of transducer typically, so while transducer produces extensional vibration, electrode slice
The consistent extensional vibration of frequency therewith can be produced.Because of ultrasonic high-frequency characteristic so that electrode slice is tired in high intensity all the time
Under labor state, the phenomenon of fracture is easily produced after work a period of time.
Secondly, electric signal is input to transducer for convenience, and existing electrode slice would generally extend two welderings in outer rim
Point, for connecting signal cable line.Because the potsherd of transducer at work can carry non-security voltage higher, in order to increase
Plus security, it is actually used in would generally increase on the transducer one protection shell, now, because electrode slice is to the size of shell
Bring limitation so that whole product cannot accomplish smaller.
The content of the invention
The technical problem to be solved in the present invention is to be easier fracture, shelling machine limitation after work for electrode slice
A kind of big deficiency of property, there is provided ultrasonic transducer that the electrode slice life-span can be substantially improved, and by changing the shape of potsherd
To obtain bigger installing space.
To solve the above problems, the technical scheme is that：
A kind of improved piezo crystals chip ultrasonic transducer, including multigroup spaced apart potsherd and electrode are provided
Piece, and located at the back shroud and front shroud at head and the tail two ends；Prestressing force screw rod passes through back shroud, potsherd, electrode slice and protecgulum
Back shroud, potsherd described in the center of plate are the consistent cyclic structure of size with electrode slice；Wherein, in back shroud and potsherd
Breach is provided with, the electrode slice surface exposed in indentation, there is provided with the welding position that voltage supplied input cable is accessed.
Improved as one kind, described each breach aligns or interlaced arrangement.
Improved as one kind, being shaped as the breach is oval, recessed moon shape, arch, sector or fan are annular.
Improved as one kind, the front shroud is provided with threaded mounting hole.
Compared with prior art, the present invention does not set up reinforcement feature but simple by doing subtraction using thinking is reverse-engineered
Change modular construction.Thus, the technical effects of the invention are that：
1st, the potsherd that transducer of the invention is used is changed into notched by traditional positive circular ring type in shape
Annular, while being adjusted accordingly to the size and shape of back shroud.So that produced ultrasonic vibration intensity and traditional form
On the premise of transducer is consistent, the situation of electrode slice fracture can be largely reduced.
2nd, the present invention is improved by back shroud, potsherd outer rim shape, by using circular ring electrode piece, significantly
The drop shadow spread for reducing electrode slice, make the design of protection shell and using scope it is more flexible.
3rd, the present invention improves the area of electrode slice welding position by the improvement design to potsherd edge shape, therefore
The intensity at the position is increased, the probability that electrode slice fracture occurs is significantly reduced.

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples, but protection scope of the present invention is not limited to
This.
Ultrasonic transducer of the invention includes the back shroud 1, potsherd 2, electrode slice 3, the front shroud 4 that are sequentially arranged, its
Middle potsherd 2 and electrode slice 3 have some groups and spaced arrangement, and have been connected with by the through its center of prestressing force screw rod 5
Come.The material of back shroud 1 can choose aluminium alloy, titanium alloy, stainless steel or steel alloy, and electrode slice 3 typically selects copper alloy or nickel
Alloy material is manufactured.A threaded mounting hole is reserved on front shroud 4, using bolt by conventional ultrasonic variable amplitude bar
(being likely to be directly connected to mould) is connected with front shroud 4.Ultrasonic transducer of the invention successively with ultrasonic transformer, supersonic mould
It is connected with ultrasonic wave driving power supply and forms a complete ultrasonic wave emission system.
In the present invention, back shroud 1, potsherd 2 are the consistent cyclic structure of size with electrode slice 3；Wherein, in back shroud
1 and potsherd 2 be provided with breach, the surface of electrode slice 3 exposed in indentation, there be provided with voltage supplied input cable access welding position.
Each breach can be alignment, or interlaced arrangement.The shape of breach has diversified forms optional, such as oval, recessed
Month shape, arch, sector or fan are annular.
The present invention makes guarantor by using the design for keeping circular outer rim, being greatly reduced the drop shadow spread of electrode slice 3
Protect the design of shell and use scope more flexible.By retain the circular of electrode slice 3 and to back shroud 1 and the shape of potsherd 2
The design of improvement, can be effectively increased electrode slice 3 and set the area of welding bit position, and increase the intensity of electrode slice 3, significantly reduce disconnected
Split the probability of generation.
