The container that integrated heating device comprises the adjustable integrated heating device pedestal of temperature 9 and is attached thereto, container content has silicone oil or transformer oil 7, insulation board II 6 and conductive plate 5 are dipped in silicone oil or transformer oil 7, polarized sample 8 is positioned on conductive plate 5, is pressed into completely in silicone oil or transformer oil 7 by conductive pole IV 4-1 of suit in through hole 4.The through hole 4 of top crown is no less than 1, conductive pole IV 4-1 supporting with through hole 4 is quite a few in one, in practice, select the through hole of varying number and the conductive pole supporting with through hole according to the actual needs of polarized sample, meet device in the general object in laboratory and factory.Can connect hours relay 10 on connecting line between the upper end of conductive pole I 3-1 simultaneously in polarization device and the positive pole of high-voltage DC power supply, accurate control can be carried out by the time of the time relay 10 to plan.
Above-mentioned polarization clamp comprises conductive pole IV and the bottom crown of suit in through hole 4, and this polarization clamp not only serves the effect of fixing leadless piezoelectric ceramics sheet, and the upper and lower surface of returning leadless piezoelectric ceramics sheet provides voltage.
Conductive pole III 3-3 for supporting top crown and bottom crown is also provided with between top crown and bottom crown, conductive pole III 3-3 is no less than 1, and the two ends of conductive pole III 3-3 are separately fixed on insulation board I 1 and insulation board II 6, and do not contact with thin conductive plate 2 and conductive plate 5.
In above-mentioned top crown and bottom crown, insulation board I 1 and insulation board II 6 select heat-resisting quantity insulation board.
And in top crown, bottom crown, polarization clamp, identical electric conducting material selected by electric conducting material, the material of electric conducting material can be any material that can conduct electricity, but in concrete enforcement, because the cost performance of copper is the highest, therefore, preferably copper is as conductive material.The material of namely above-mentioned thin conductive plate 2, conductive plate 5, conductive pole I 3-1, conductive pole IV 4-1, conductive pole II 3-2, conductive pole III 3-3 is copper.
As shown in Fig. 1 ~ Fig. 5, as a kind of execution mode, selection copper is conductive material, selects top crown and bottom crown to be rectangle, the number of copper post III 3-3 is two, together with copper post II 3-2, copper post I 3-1, be distributed in four angles of top crown and bottom crown, well support top crown and bottom crown, simultaneously in the present embodiment, the number selecting through hole 4 is 5, accordingly when polarizing shown in Fig. 3, Fig. 4, Fig. 5, selects 5 copper post IV 4-1.
In above-mentioned polarization device, when connecting high-voltage DC power supply, sheet copper 2 on top crown is connected with the positive pole of high-voltage DC power supply by copper post I 3-1, therefore electromotive force is just, copper post II 3-2 upper end is connected with the ground wire of high-voltage DC power supply by wire, when connecting high-voltage DC power supply, electromotive force on bottom crown on copper foil 5 is zero, therefore, copper post I 3-1 and copper post II 3-2 not only plays the effect supporting top crown and bottom crown, provide electrical potential difference for top crown and bottom crown, i.e. voltage simultaneously.And copper post III 3-3 is not connected with any one copper coin, only play the effect of pillar.Through hole 4 is set to the certain circular hole of radius, when needs polarize to polarized sample, actual conditions per sample and quantity, select copper post IV 4-1 of suitable number, the diameter of copper post IV 4-1 is close with the diameter of through hole 4, utilizes the gravity of copper post IV 4-1 self to be firmly pressed on bottom crown by leadless piezoelectric thin slice.Because copper post IV 4-1 inserted in through hole 4 contacts with the sheet copper 2 on top crown, so the electromotive force of the upper surface of leadless piezoelectric thin slice 8 can be made equal with the positive electrode potential of high-voltage DC power supply.For bottom crown, when polarized sample, because the lower surface of sample contacts with copper coin 5, so the electromotive force of polarized sample lower surface is also zero.
When specifically polarizing, first will the sample 8 of polarization be needed to be placed on copper coin 5, then copper post identical with through hole 4 for diameter is pressed in the upper surface of polarized sample through the through hole 4 on top crown, due to the Action of Gravity Field of copper post self, need the polarized sample of polarization can be fixed on firmly between copper post and bottom crown.When connecting high-voltage DC power supply, the upper surface of polarized sample is communicated with the positive pole of power supply by pressure copper post thereon, electromotive force be on the occasion of, lower surface is connected with ground wire by contact bottom crown, electromotive force is zero, there is electrical potential difference up and down like this in polarized sample between two surfaces, by regulating the magnitude of voltage of high-voltage DC power supply, change and be added in upper and lower two the surperficial magnitudes of voltage of polarized sample, it is polarized.Bottom crown is placed in silicone oil or transformer oil 7 with needing the polarized sample polarized simultaneously.By regulating integrated heating device, the temperature of silicone oil or transformer oil in adjustable integrated heating apparatus container, and then controlling the poling temperature of polarized sample, being controlled by the time of the time relay 10 to polarization simultaneously.When improving poling temperature, can the polarization time be shortened, enhance productivity.
When leadless piezoelectric ceramics sheet, lead-free piezoelectric thin film or lead-free piezoelectric thick film are polarized, when they are not polarized in silicone oil or transformer oil, poling temperature not only can be made to keep constant, and leadless piezoelectric ceramics sheet, lead-free piezoelectric thin film or lead-free piezoelectric thick film and air exclusion can be made, not only avoid exposed the polarization in atmosphere of leadless piezoelectric ceramics sheet, lead-free piezoelectric thin film or lead-free piezoelectric thick film easily to puncture but also unsafe shortcoming, the coefficient of safety that both improve operating environment turn improves rate of finished products.
In the use procedure of equipment, can according to the quantity of the sheet number that once polarizes, the quantity of adjustment through hole 4 and the copper post through through hole 4, this apparatus structure is simple, be easy to operation, poling temperature and polarization time adjustable controlled, the place such as laboratory and Corporation R & D can be used for can be used for again the places such as factory mass production, lead piezoelectric ceramics sheet, lead-free piezoelectric thin film or lead-free piezoelectric thick film and air insulated can be accomplished in polarization process, not only increase the fail safe of operation, turn improve rate of finished products.
