Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, the fingerprint module automatic impedance-testing device of the utility model, including pedestal 10, on pedestal 10 simultaneously
Row is equipped with four groups of fingerprint module test suites 20, and each fingerprint module test suite 20 includes fixture 21 and probe groups, fixture 21
For fixing fingerprint module 50, probe groups towards fixture 21 and can opposed jaw 21 move.Specifically, probe groups include being used for
The positive probe 22 and negative probe 23 being connect with impedance instrument or multimeter, positive probe 22 connect respectively with negative probe 23
Probe fixed block 24 is connected to, each probe fixed block 24 by a cylinder 30 driving being arranged on pedestal 10 move simultaneously by longitudinal direction
It is dynamic.
In order to which two probes in every group of fingerprint module test suite 20 is made all smoothly to move, accurately to touch finger
Two testing impedance points of line module 50, every group of fingerprint module test suite 20 of the utility model further include two 25 Hes of sliding rail
Driving plate 26, two sliding rails 25 are arranged in parallel on pedestal 10 and are slidably connected respectively with two probe fixed blocks 24, driving plate
26 are slidably connected with two sliding rails 25 and are connect with cylinder 30, and driving plate 26 is used to drive two probe fixed blocks 24 along sliding rail 25
It slides.
In order to control pressure of the probe to fingerprint film group 50, the utility model is in every group of fingerprint module test suite 20
The guide rod 27 for driving plate 26 to be guided to move is respectively connected between driving plate 26 and two probe fixed blocks 24, positioned at driving
Spring 28 is arranged on guide rod 27 between plate 26 and probe fixed block 24.In this way, when the telescopic arm of cylinder 30 stretches out, drive
Movable plate 26 is moved along sliding rail 25 towards fingerprint module 50, and in moving process, driving plate 26 compresses spring 28, and spring 28 compresses probe
Fixed block 24 so as to which probe fixed block 24 be driven to be moved along sliding rail towards fingerprint module 50, makes positive probe 22 and negative probe
