Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
As shown in figure 1, being set side by side on the fingerprint module automatic impedance-testing device of the present invention, including pedestal 10, pedestal 10
There are four groups of fingerprint module test suites 20, each fingerprint module test suite 20 includes fixture 21 and probe groups, and fixture 21 is used for
Fixed fingerprint module 50, probe groups towards fixture 21 and can opposed jaw 21 move.Specifically, probe groups include being used for and resistance
The positive probe 22 and negative probe 23 of anti-tester or universal meter connection, positive probe 22 are connected to negative probe 23
Probe fixed block 24, each probe fixed block 24 is driven while vertically moving by a cylinder 30 being arranged on pedestal 10.
In order that two probes in every group of fingerprint module test suite 20 are all smoothly moved, to touch finger exactly
Two testing impedance points of line module 50, every group of fingerprint module test suite 20 of the invention also includes two slide rails 25 and driving
Plate 26, two slide rails 25 are set in parallel on pedestal 10 and are slidably connected respectively with two probe fixed blocks 24, driving plate 26 with
Two slide rails 25 are slidably connected and are connected with cylinder 30, and driving plate 26 is used to drive two probe fixed blocks 24 to slide along slide rail 25
It is dynamic.
In order to control probe to the pressure of fingerprint film group 50, driving of the present invention in every group of fingerprint module test suite 20
The guide rod 27 for guiding driving plate 26 to move is respectively connected between plate 26 and two probe fixed blocks 24, positioned at driving plate 26
Spring 28 is arranged with guide rod 27 between probe fixed block 24.In this way, when the telescopic arm of cylinder 30 stretches out, driving plate
26 move along slide rail 25 towards fingerprint module 50, in moving process, and driving plate 26 compresses spring 28, and spring 28 compresses probe and fixed
Block 24, so as to drive probe fixed block 24 to be moved along slide rail towards fingerprint module 50, makes positive probe 22 and the court of negative probe 23
Two testing impedance points of fingerprint module 50 are moved and contacted to fingerprint module 50, when positive probe 22 is contacted with negative probe 23
To after two testing impedance points, due to the elastic reaction of spring 28, when cylinder 30 continues to press by driving plate 26, spring
28 accumulation elastic potential energys, continue to apply more pressure to fingerprint module, so that it is guaranteed that positive probe 22 is with bearing to reduce probe
Pole probe 23 can contact with testing impedance point and be avoided that positive probe 22 is applied with negative probe 23 to fingerprint module well
Press through big damage fingerprint module.
For the sake of attractive in appearance, using housing by the driving plate 26 in every group of fingerprint module test suite 20, guide rod 27,
Spring 28 and probe fixed block 24 are framed.The group fingerprint module test suite of the leftmost side one shown in Fig. 1 is to remove housing
Other three groups of fingerprint module test suites have been respectively mounted housing in structure afterwards, Fig. 1.
In order that a cylinder 30 can drive the driving plate 26 in four groups of fingerprint module test suites 20 simultaneously, the present invention will
Connected between driving plate 26 in adjacent fingerprint module test suite 20 by connecting plate 40.In this way, cylinder 30 starts, four drives
Dynamic plate 26 is moved along slide rail 25 simultaneously, and four groups of fingerprint module test suites 20 are tested four fingerprint modules respectively simultaneously.
During work, by fingerprint module 50 be put into fixture 21 (fixture here be those skilled in the art it is usually used, according to finger
The structure of the shape respective design of line module, is not repeated here) on be fixed；Press switch 60 (being arranged on pedestal 10)
Afterwards, cylinder 30 moves downward 23 points of positive probe 22 and negative probe in distance to a declared goal, every group of fingerprint module test suite 20
Do not touch and show impedance value on two testing impedance points of fingerprint module 50, testing impedance instrument；After certain time, for example may be used
To be 10 seconds, cylinder 30 moves back into initial position upwards, and testing impedance terminates.
It can be seen that, fingerprint module automatic impedance-testing device of the invention can once carry out the resistance of four fingerprint modules automatically
Anti- test, it is simple to operate, and the quantity of cylinder is saved, cost is saved, testing efficiency is improved.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's
Principle, and limiting the scope of the invention can not be construed in any way.Based on explanation herein, the technology of this area
