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 mechanism 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, probe groups and cylinder 30, fixture
21 are used to fix fingerprint module 50, probe groups towards fixture 21 and can opposed jaw 21 move, cylinder 30 is used to drive correspondence
Probe groups vertically move.Specifically, probe groups include being used for the positive probe 22 that is connected with impedance instrument or universal meter and
Negative probe 23, positive probe 22 is connected to probe fixed block 24, every group of fingerprint module test suite with negative probe 23
Two probe fixed blocks 24 in 20 are driven while vertically moving by the cylinder 30 in this group of fingerprint module test suite 20.
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 connected with corresponding cylinder 30, and driving plate 26 is used to drive two probe fixed blocks 24 along slide rail
25 slide.
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, with the gas
The driving plate 26 that cylinder 30 is connected is moved along slide rail 25 towards fingerprint module 50, and in moving process, driving plate 26 compresses spring 28, bullet
Spring 28 compresses probe fixed block 24, so as to drive probe fixed block 24 to be moved along slide rail 25 towards fingerprint module 50, visits positive pole
Pin 22 moves towards fingerprint module 50 with negative probe 23 and contacts two testing impedance points of fingerprint module 50, works as positive probe
22 are touched after two testing impedance points with negative probe 23, and due to the elastic reaction of spring 28, driving is being passed through when cylinder 30
When plate 26 continues to press, the accumulation elastic potential energy of spring 28 continues to apply more pressure to fingerprint module to reduce probe, so that
Ensure that positive probe 22 can be contacted with testing impedance point well with negative probe 23 and be avoided that positive probe 22 and negative pole
Probe 23 is to the excessive damage fingerprint module of fingerprint module pressure.
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,
