Description
Technical field
The present invention relates to transducer technology field, in particular to a kind of raising high-frequency wide-beam transmitting transducer reliability
Method.
Background technique
Improving the method for high-frequency wide-beam transmitting transducer reliability at present is in the wrapped one layer of expoxy glass fibre of radiating surface
Tie up cloth composite layer.As shown in Figure 1, fixing two fixing screws 13 on the metal base of energy converter 14 first, then exist
The radiating surface of ceramics 12 coats epoxy resin, with the both ends of fixing screws 13 wrapped glass fabric 11 back and forth；Wrapped glass fibers
Apply pulling force when tieing up cloth 11, is in close contact glass cloth and ceramic 12 radiating surfaces, and make glass fabric 11 and epoxy resin
Sufficiently infiltration makes epoxy resin cure form epoxy glass fiber cloth composite layer, ring by the regular hour at high temperature
There are convergent force when oxygen resin solidification, epoxy glass fiber cloth composite layer applies certain answer to ceramics using convergent force
Power improves transmitting transducer reliability.
Due to fix glass cloth on fastening screw 13, it will usually so that the expoxy glass at the radiating surface both ends of ceramics 12
Cloth composite layer out-of-flatness causes directive property fluctuating to become larger.Since 13 area of fastening screw is small, when the width of radiating surface is larger
When (more than 15mm), the wrapped number of plies are thicker, it is difficult to using the method for above-mentioned wrapped one layer of epoxy glass fiber cloth composite layer
It realizes.
Summary of the invention
The purpose of the present invention is to provide a kind of methods for improving high-frequency wide-beam transmitting transducer reliability, existing to solve
The problem of some methods are difficult to realize in the case where the width of radiating surface is big or the wrapped number of plies is thicker.
In order to solve the above technical problems, the present invention provides a kind of side for improving high-frequency wide-beam transmitting transducer reliability
Method includes the following steps:
Glass fabric is wrapped around metal base and the whole circle of ceramics progress；
At the both ends of metal base, mounting plate fixes glass fabric respectively, glass fabric and the epoxy coated in advance
Epoxy glass fiber cloth composite layer is collectively formed in resin；
It polishes epoxy glass fiber cloth composite layer, removes fixed plate.
Optionally, the metal base bottom be equipped with preformed groove, it is whole circle it is wrapped when glass fabric be placed in preformed groove.
Optionally, the both ends of the metal base are respectively equipped with mounting plane.
Optionally, the fixed plate is mounted on the both ends of the metal base by fastening screw.
Optionally, the epoxy resin is coated in the radiating surface of the ceramics.
A kind of method for improving high-frequency wide-beam transmitting transducer reliability is provided in the present invention, by glass fabric
It is wrapped that whole circle is carried out around metal base and ceramics；Distinguish mounting plate at the both ends of metal base to consolidate glass fabric
Fixed, epoxy glass fiber cloth composite layer is collectively formed in glass fabric and the epoxy resin coated in advance；To expoxy glass
Fiber cloth composite layer is polished, and fixed plate is removed.The whole circle of epoxy glass fiber cloth composite layer is wrapped, complete after solidification
Whole no breakpoint；The bottom of metal base is equipped with preformed groove, for placing glass fabric, and without removal when installing assembly.
It is wrapped that this method progress also can be used at the width of radiating surface larger (more than 15mm), can be used for the width direction of radiating surface
The phased or lesser transmitting transducer of launching beam width of upper needs.

Specific embodiment
It can to a kind of raising high-frequency wide-beam transmitting transducer proposed by the present invention below in conjunction with the drawings and specific embodiments
Method by property is described in further detail.According to following explanation and claims, advantages and features of the invention will be more clear
Chu.It should be noted that attached drawing is all made of very simplified form and using non-accurate ratio, only to conveniently, lucidly
Aid in illustrating the purpose of the embodiment of the present invention.
Embodiment one
The present invention provides a kind of method for improving high-frequency wide-beam transmitting transducer reliability, process is as shown in Figure 2.It is described
The method for improving high-frequency wide-beam transmitting transducer reliability includes the following steps:
Step S21, wrapped around metal base and the whole circle of ceramics progress by glass fabric；
Step S22, at the both ends of metal base, mounting plate fixes glass fabric respectively, glass fabric and applies in advance
Epoxy glass fiber cloth composite layer is collectively formed in the epoxy resin covered；
Step S23, it polishes epoxy glass fiber cloth composite layer, removes fixed plate.
Specifically, the both ends of the metal base 21 are respectively equipped with mounting plane, and set below the metal base 21
Just like preformed groove shown in Fig. 3；Epoxy resin is coated in the radiating surface of ceramics 22；As shown in figure 4, glass fabric 23 is surrounded
Metal base 21 and ceramics 22 carry out it is whole circle it is wrapped, it is whole circle it is wrapped when glass fabric 23 be placed in preformed groove；Referring next to
Fig. 5 passes through 25 mounting plate 24 of fastening screw in mounting plane, by glass fibre at the both ends of the metal base 21 respectively
Cloth is fixed, and makes epoxy resin cure and glass fabric that epoxy glass fiber cloth be collectively formed by the regular hour at high temperature
Composite layer；It polishes epoxy glass fiber cloth composite layer, removes fastening screw 25 and fixed plate 24, reduce empty
Between waste.
In the method provided by the invention for improving high-frequency wide-beam transmitting transducer reliability, to the wrapped glass fibre of ceramics
Cloth generates convergent force when using epoxy resin cure, applies stress to ceramics, improves transmitting transducer reliability；Glass fibre
Cloth is wrapped around metal base and the whole circle of ceramics, and completely without breakpoint after solidification, generation convergent force is uniform, is conducive to improve directive property
It rises and falls；Fastened after wrapped using fixed plate, it is easy to operate, compared to method before can realize according to actual needs multilayer around
Packet.
