Double screen ultrasonic probe of the invention has the following advantages that：Due to using double-screen structure design, enable it to by
The information detected shows more complete, improves its detection accuracy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of double screen ultrasonic probe of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description.
As shown in Figure 1, double screen ultrasonic probe of the invention, including shell 1, conductive lever is provided in the shell 1
2,2 lower end of conductive lever is provided with lug plate 3, and 3 lower end of lug plate is provided with connecting line 4, and the connecting line 4 is arranged
Block 6 is absorbed in being provided in a storage space 5 in the storage space 5,6 lower end of absorption block is provided with protective film 7, institute
It states and is provided with piezoelectric chip 8 between protective film 7 and the absorption block 6, the side of the conductive lever 2 is provided with the first screen 9,
The other side is provided with the second screen 10.
Further, first screen 9 and the second screen 10 are LCD Panel.
Further, the receiving sheet 3 is electrode.
Further, the absorption block 6 is formed by damping wafer fabrication.
Further, the damping chip is formed by tungsten powder and epoxy preparation.
Further, the protective film 7 is the film that metal material is made.
Further, the metal material is Steel material.
Further, first screen 9 and the second screen 10 are electrically connected with the connecting line 4.
Further, the piezoelectric chip 8 is piezoelectric ceramic wafer.
Further, the material of the shell 1 is plastic material or metal material.
Specifically, wherein piezoelectric chip 8 is mainly used for emitting and receives ultrasonic wave, piezoelectric chip 8 is pressed by piezoelectric single crystal
Certain way and certain orientation cutting are formed or are made of piezoelectric ceramics through polarization.8 two sides of piezoelectric chip is covered with as electrode
Silver layer keeps the voltage for supplying piezoelectric chip 8 uniform, and 8 top electrode of piezoelectric chip line of starting to exchange fire leads to circuit, bottom surface be then grounded mouth with
The common point of circuit connects to be formed into a loop.The effect of protective film 7 is protection piezoelectric chip 8 and electrode, prevents from wearing and touch
Bad, protective film must wear-resisting property be good, intensity is high, material acoustic attenuation is small, sound translative performance is good, thickness is suitable, and protective film is divided into soft
Protective film and hard protecting film；Hard protecting film often uses aluminium oxide (corundum), sheet metal etc. to be made, and soft protective film often uses poly-glue fat soft
Plastics are made.The back side that block is adhered to piezoelectric chip 8 is absorbed, effect is to prevent the inertial oscillation and absorption pressure of piezoelectric chip 8
The sound energy of electric 8 back side radiant of chip, to reduce pulse width and noise signal interference.In pulse reflection method flaw detection, need
Stationary state is recovered immediately after chip vibration, prepares receives echo-signal, the vibration that continues of piezoelectric chip 8 will affect echo letter
Number reception, result increases blind area, and resolving power reduces.In addition, sound can from two sides before and after piezoelectric chip while be emitted,
The sound of back side radiant, which can return to chip, will generate noise signal.Increase braking absorption medium in back surface of the wafer, on the one hand can hinder
The only inertial oscillation of piezoelectric chip 8, the sound energy that on the other hand absorbable back surface of the wafer radiates again.However detectable signal is fed back to
First screen 9 and the second screen 10.Shell 1 is made of metal or plastics, it plays work that is fixed and protecting entire probe element
With, on shell 1 have probe cable connector, have screw socket, also there is socket or bayonet etc..
Obviously, described embodiment is only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts all other
Embodiment shall fall within the protection scope of the present invention.
