Embodiment
Improve an installation method for infrared imaging detector environmental suitability, comprise the steps:
Step one: processing U-type groove
Detector fixed base plate 11 processes U-type groove, and the position of U-type groove is arranged on the side of detector fixed base plate 11 near detector focal plane 6.This U-type groove is for installing elasticity trim ring, and therefore the size of U-type groove is mated with elasticity trim ring.
Step 2: install sensing circuit plate
Sensing circuit plate 8 is installed on detector 1.Described sensing circuit plate 8 arranges contact pin groove, and detector 1 is provided with the contact pin corresponding with contact pin groove.Only need the contact pin Matching installation on the contact pin groove of sensing circuit plate 8 and detector 1 when installing.
Step 3: install detector
First by detector fixed base plate 11 horizontal positioned, the elasticity lower clamping ring 10 of elasticity trim ring is placed in the U-type groove held successfully in advance, then the detector 1 with sensing circuit plate 8 in step 2 is placed on detector fixed base plate 11, during placement with detector fixed base plate 11 with tommy 13 locate, again with detector gib screw 12, detector 1 is fixedly connected with detector fixed base plate 11, then trim ring in elasticity 9 is placed on elasticity lower clamping ring 10, and with screw, trim ring in elasticity 9 and elasticity lower clamping ring 10 are fixedly connected to form complete elasticity trim ring.
Described elasticity trim ring is elastic fixing part, and teflon can be selected as the making material of elasticity trim ring.
Step 4: fixed mount after installation sensing circuit plate
Fixed mount 4 after sensing circuit plate is set between sensing circuit plate 8 and elasticity trim ring, fixed mount 7 before the opposite side of sensing circuit plate 8 arranges sensing circuit plate, then fixes with sensing circuit plate gib screw 5 pairs of sensing circuit plates 8.When sensing circuit plate 8 is fixed, utilize the protruding circular ring that detector 1 is arranged, fastening towards the direction of elasticity trim ring from the outside of protruding circular ring with sensing circuit plate gib screw 5, now fixed mount 7 before fixed mount 4, sensing circuit plate 8 and circuit board after sensing circuit plate is fastenedly connected by sensing circuit plate gib screw 5, and the above-mentioned parts be fastenedly connected are spacing by elasticity trim ring.
With the detector 1 that the method for the application is installed; the cantilever of elasticity trim ring to detector 1 is utilized to be fixed; simultaneously because elasticity trim ring has characteristic that is spacing and portion deforms buffering, can well protect the cantilever of detector 1 can not damage in vibration because remainder fixes tension when fixed detector 1.The application to be provided with after sensing circuit plate fixed mount 7 before fixed mount 4 and circuit board in addition, is fixed on detector 1 by sensing circuit plate 8, avoids sensing circuit plate 8 and come off in vibration with above-mentioned two fixed mounts.
Applicant has also done contrast test to the resistance to shock of the detector 1 installed by the application's method, and test result is as follows: at present, take the tolerance vibration mechanics of direct hard-wired detector as shown in table 1 below, far can not meet current demand.
Vibration adaptation environment before table 1 mounting means improves
The vibration environment adaptive faculty test result of the detector installed by the application is as table 2.
Vibration adaptation environment after table 2 mounting means improves
As can be seen from the contrast of two forms, when providing identical vibration frequency point (frequency in table), the power spectrum density of the detector installed by the application's method obviously increases, then always root-mean-square value also just obviously becomes large, and the resistance to shock of the detector of therefore the application's method installation is obviously better than the detector of conventional art installation method installation.
