Specific embodiment
Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
As shown in Figure 1, the fingerprint module automatic impedance-testing mechanism of the present invention, including pedestal 10, sets side by side on 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 for fixing fingerprint module 50, probe groups towards fixture 21 and can opposed jaw 21 move, cylinder 30 is for driving correspondence
Probe groups longitudinal movement.Specifically, probe groups include for the positive probe 22 that is connected with impedance instrument or universal meter and
Negative probe 23, positive probe 22 are 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 are vertically moved by the cylinder 30 in this group of fingerprint module test suite 20.
In order to which two probes in every group of fingerprint module test suite 20 is made all smoothly to move, to touch finger exactly
Two testing impedance points of line module 50, every group of fingerprint module test suite 20 of the invention further include two slides 25 and drive
Movable plate 26, two slides 25 are arranged in parallel on pedestal 10 and are slidably connected respectively with two probe fixed blocks 24, driving plate 26
It is slidably connected with two slides 25 and is connected with corresponding cylinder 30, driving plate 26 is used to drive two probe fixed blocks 24 along cunning
Rail 25 slides.
In order to control pressure of the probe to fingerprint film group 50, drive of the present invention in every group of fingerprint module test suite 20
The guide rod 27 that driving plate 26 is guided to move is respectively connected between movable plate 26 and two probe fixed blocks 24, positioned at driving plate
Spring 28 is arranged on guide rod 27 between 26 and probe fixed block 24.In this way, when the telescopic arm of cylinder 30 stretches out, with this
The driving plate 26 that cylinder 30 connects is moved along slide 25 towards fingerprint module 50, and in moving process, driving plate 26 compresses spring
28, spring 28 compresses probe fixed block 24, so as to which probe fixed block 24 be driven to be moved along slide 25 towards fingerprint module 50, makes
Positive probe 22 moves towards fingerprint module 50 with negative probe 23 and contacts two testing impedance points of fingerprint module 50, when just
After pole probe 22 touches two testing impedance points with negative probe 23, due to the elastic reaction of spring 28, lead to when cylinder 30
When plate 26 of overdriving continues pressure, spring 28 accumulates elastic potential energy, continues to apply fingerprint module more pressures to reduce probe
Power, so that it is guaranteed that positive probe 22 and negative probe 23 with testing impedance point contact and can be avoided that positive probe well
22 with negative probe 23 to fingerprint module pressure it is excessive damage fingerprint module.
For the sake of beauty, using outline border by every group of fingerprint module test suite 20 driving plate 26, 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 outline border
Structure afterwards, other three groups of fingerprint module test suites have been respectively mounted outline border in Fig. 1.
In the present invention, four groups of probe groups are operated alone respectively by corresponding cylinder 30, for convenience of four cylinders 30 are installed, this
Invention is equipped with the support plate 40 for supporting four cylinders 30 simultaneously on pedestal 10.Four cylinders 30 can drive corresponding probe simultaneously
Group also can drive corresponding probe groups during difference.As the preferred embodiment of the present invention, the present invention is additionally provided on pedestal 10
The switch 60 of each cylinder 30 start and stop simultaneously is controlled, makes four cylinders 30 while drives corresponding probe groups, while respectively to four
Fingerprint module 50 is tested, and can improve work efficiency.
During work, by fingerprint module 50 be put into fixture 21 (fixture here for those skilled in the art it is usually used, according to finger
The structure of the shape respective design of line module, does not repeat here) on be fixed；After lower switch 60, four cylinders 30 are same
When move downward distance to a declared goal, the positive probe 22 in every group of fingerprint module test suite 20 is respectively contacted with negative probe 23
Two testing impedance points of fingerprint module 50 show impedance value on testing impedance instrument；After a certain period of time, such as can be 10
Second, four cylinders 30 move upwards simultaneously returns to initial position, and testing impedance terminates.
As it can be seen that the fingerprint module automatic impedance-testing device of the present invention can once carry out the resistance of four fingerprint modules automatically
Anti- test, it is easy to operate, cost is saved, improves testing efficiency.
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 cannot be construed in any way.Based on explanation herein, the technology of this field
Personnel would not require any inventive effort the other specific embodiments that can associate the present invention, these modes are fallen within
