Polarization process is optimized, and improves some problems that current polarization clamp is present, and improves the efficiency and effect of polarization, reduction polarization
Cost, improve piezoelectric transducer sensitivity and sensing accuracy be particularly important.
In view of this, the present invention is directed to propose the piezoelectric membrane polarization clamp that a kind of multichannel can be clamped, existing to solve
Some contradictions present in Polarization technique：（1）Piezoelectric membrane polarization area is small, and polarization speed is slow, and efficiency is low, and cost is high；（2）Pressure
Conductive film polarization area is big, and polarizing voltage is low, and the effect after polarization is poor, and sensitivity is low；（3）Piezoelectric membrane and polarization sheet metal it
Between fit not tight, electric arc can be produced during polarization, causes film easily to puncture, is difficult to obtain high-quality product.
The content of the invention
The utility model proposes that the purpose is to provide a kind of piezoelectricity of multichannel to solve the problem of prior art is present
Membrane polarization fixture.
The technical solution of the utility model is：A kind of piezoelectric membrane polarization clamp of multichannel, including deckle board is clamped, it is described
The loading steel plate for being provided with close to or away from and being parallel to each other in the space that deckle board is enclosed is clamped, the loading steel plate two is relative
The polarization copper sheet for clamping piezoelectric membrane is provided with end face.
Positive outside wire or negative outside wire are provided with the opposite end face of the polarization copper sheet.
The polarization copper sheet is connected with positive outside wire, negative outside wire by pad, described and DC high-voltage power supply
Earth leakage protective device be connected.
The polarization copper sheet independently forms loop.
The clamping deckle board is in "] " font, the clamping deckle board biside plate is relative to preset nut.
The loading steel plate back is provided with fishbolt, and the fishbolt external screw thread is meshed with nut.
The clamping deckle board is formed using epoxy resin integral cast.
The loading steel plate end face formation assembling nib, the polarization copper sheet back forms connection mould post, the connection mould
Post is fixed in assembling nib.
The assembling nib is hexagon, and the connection mould post shapes are adapted with assembling nib.
The polarization copper sheet is with being connected the shaping of mould post formed by integrally casting.
The beneficial effects of the utility model are as follows：
（1）The polarization clamp of large area is changed to the single facet of multichannel by the invention by the design of multichannel
Loop is formed alone between product fixture, each passage, is not interfere with each other, this improvement improves the polarizing voltage of film.It is especially right
For PZT/PVDF piezo-electricity composite materials film or the later PVDF thin film of stretching, area is bigger, internal existing defects
Possibility is bigger, and local breakdown possibility is bigger in polarization process.So from polarization area for this angle
Bigger, the polarizing voltage that can apply during polarization is lower, and the sensitivity of the film after polarization is lower, so this programme solution
Determine this problem, improved polarizing voltage, improve the sensitivity of piezoelectric transducer.
（2）The invention in polarization process, can pass through and clamp in the clamping device setting up and down of polarization copper sheet
Bolt, makes polarization copper sheet tightly be fit together with piezoelectric membrane, so as to prevent the copper sheet and thin of being polarized in polarization process
There are closed air bubbles between film, prevent high-voltage arc from forming caused film breakdown.
（3）The multi-passage design of the invention, by increasing the quantity of polairzed area, improves the polarization of piezoelectric membrane
Speed, reduces cost, and preparation work is simple, workable, can carry out large-scale industrial production.
