Fingerprint mould is installed also referring to the fingerprint mould group test fixture that Fig. 1 (a) and Fig. 6, Fig. 6 are the embodiment of the present application six
The structural schematic diagram of group.The structure of embodiment six and the structure of embodiment one are essentially identical, the difference is that, in the present embodiment
In, the support base 100 offers container 100a, when the fingerprint mould group test fixture 10 is to the finger of the electronic device 1
When line mould group 1A is tested, the container 100a is used to accommodate and fix the display screen 500 of the electronic device 1, institute
Display screen 500 is stated for showing the fingerprint mould group test fixture 10 to the test result of fingerprint mould group 1A.
Specifically, in another embodiment, the container 100a is also used to accommodate and fix the electronic device 1
Main circuit board 600, the main circuit board 600 are electrically connected with the fingerprint mould group 1A by flexible circuit board, the fingerprint mould group
The finger print information of 1A acquisition is transmitted to the main circuit board 600 via the flexible circuit board.
It should be noted that when carrying out functional test to fingerprint mould group 1A using fingerprint mould group test fixture 10, firstly,
Fingerprint mould group 1A is installed on locating piece 200, press device 300 is then adjusted, so that press device 300 and fingerprint mould group 1A
Then face controls press device 300 and moves towards the direction close to locating piece 200, so that the emulation on press device 300
Finger 410 presses fingerprint mould group 1A.Since flexible circuit board is connected between main circuit board 600 and fingerprint mould group 1A,
When the artificial finger 410 on press device 300 presses fingerprint mould group 1A, with the fingerprint on gathering simulation finger 410
When information, the finger print information is transmitted on the main circuit board 600 by flexible circuit board, then on main circuit board 600
Processor handles the finger print information, and will store in the memory in treated result and main circuit board 600
Comparison data compares and analyzes, and obtains comparison result.And form and be electrically connected between display screen 500 and main circuit board 600, because
This, comparison result is transmitted to electronic device 1 and obtains display screen 500 by main circuit board 600, and then by comparison result in display screen 500
On show.When being consistent according to the comparison data stored in the collected fingerprint of artificial finger 410 and memory, it is believed that refer to
The function of line mould group 1A is intact, can show " OK " on display screen 500；When according to the collected fingerprint of artificial finger 410 with
When the comparison data stored in memory is not inconsistent, it is believed that the function of fingerprint mould group 1A is defective, can show on display screen 500
" NG " avoids being installed on electronic device 1 using fingerprint mould group 1A to need that fingerprint mould group 1A is repaired or replaced
In, to just be tested the function of fingerprint mould group 1A before installing fingerprint mould group 1A, discovery fingerprint mould group 1A early
It is whether defective, it avoids having defective fingerprint mould group 1A and is installed in electronic device 1, therefore the electronic device 1 after general assembly produces
Life is bad.
It is the structural representation of the fingerprint mould group test fixture of the embodiment of the present application seven also referring to Fig. 1 (a) and Fig. 7, Fig. 7
Figure.The structure of embodiment seven and the structure of embodiment one are essentially identical, the difference is that, in the present embodiment, the fingerprint
Mould group test fixture 10 further includes levelling device 700, and the levelling device 700 is for adjusting the support base 100 and horizontal plane
Between tilt angle.
Wherein, levelling device 700 can be level meter.Level meter is a kind of common measurer for measuring low-angle.In machinery
In industry and instrument manufacture, for measuring the flatness and straight line at the inclination angle relative to horizontal position, lathe class equipment guide rail
Degree, the horizontal position of equipment installation and upright position etc..It can be divided by the shape difference of level meter: Universal level-metre, cylinder water
Level, integrated water level, mini level meter, camera level meter, frame level, ruler formula level meter；By the fixation of spirit level
Mode can be divided into again: adjustable water level and can not mode level meter.
In a better embodiment, when the support base 100 is 0 compared to the angle of horizontal plane, at this time, it is believed that pressing
Pressure device 300 and locating piece 200 are also horizontally arranged, at this point, press device 300 is to the fingerprint mould group being installed on locating piece 200
The direction of the pressing force of 1A and the fingerprint mould group 1A face, help avoid fingerprint mould group 1A and the case where unbalance stress occur,
So as to provide uniform pressing dynamics to fingerprint mould group 1A, fingerprint mould group test fixture 10 is helped to improve to fingerprint mould group
The detection accuracy of 1A.
Specifically, in use, first being leveled using levelling device 700 to the support base 100, so that described
Support base 100 is located in same level, and then fingerprint mould group 1A is placed on the locating piece 200 again and is fixed, then again
So that fingerprint mould group 1A described in 300 face of press device is pressed, the stress of fingerprint mould group 1A is helped so that more
Uniformly.
It is the fingerprint module group test system that one preferred embodiment of the application provides also referring to Fig. 1 (a) and Fig. 8, Fig. 8
