Set detection signal simultaneously receives feedback information, to reach the purpose to function built-in testing.Single-layer multi-point capacitive touch screen functional sheet
It is common because requirement on machining accuracy is high and caused by short circuit itself, open circuit situation it is relatively more, directly reach the standard grade, can lead if being not added with testing
Cause TP bad, material and manually waste bigger.
When being tested using probe functional sheet, probe requirement on machining accuracy is higher, so processing is more difficult, leads
Costly, probe is accomplished that the golden finger one on the golden finger and functional sheet on flexible PCB to the cost of cause test device
One correspondence.When the golden finger on design function piece especially more (reach more than 100), it is especially thin when, utilized due to probe
It is profile positioning, probe itself is also limited (too thin pin is easily broken and deforms) by minimum diameter, and aligning accuracy is poor.Due to
Profile position and PIN it is tiny the reason for, cause test accuracy it is very low, additionally, due to being used for multiple times, its probe easily damages
It is bad, improve with causing testing cost.
When being tested using the false pressure FPC of silica gel functional sheet, due to multiple use, silica gel elastomeric deformable is insufficient,
Cause FPC and the easy loose contact of sensor function piece, while during vacation is pressed, easy off normal, test can not be ensured
Accuracy and precision.Therefore a kind of exploitation for testing high, the accurate high single-layer multi-point capacitive touch screen test device of accuracy
It is necessary.

Embodiment
As shown in Figures 1 to 3, single-layer multi-point capacitive touch screen test device of the invention, the test device are true positioned at taking out
In empty device 3, test device includes the upper support plate 1 being mutually correspondingly arranged and lower support plate 2, and the lower surface of upper support plate 1, which is provided with, to be used for
The groove I11 of FPC is placed, groove I11 is used to place and fixing flexible wiring board, during fluting, it is impossible to mistake
Deep, groove I11 depth is slightly less than the thickness of FPC, so as to ensure that FPC can protrude the upper following table of support plate 1
The horizontal plane in face；The lower upper surface of support plate 2 is provided with the groove II21 for being used for placing functional sheet to be measured, and groove II21 is used to place and consolidate
Fixed functional sheet to be measured, equally can not be too deep during fluting, and groove II21 depth is slightly less than the thickness of functional sheet to be measured
Degree, so as to ensure that functional sheet to be measured can protrude the horizontal plane of lower support plate upper surface, groove I11 is mutually corresponding with groove II21；
Upper support plate 1 and lower support plate 2 are flexible contact, after upper support plate 1 and lower support plate 2 closure, upper support plate 1 and lower support plate 2 it
Between there is gap, test device of the invention is located in vacuum extractor 3, and vacuum extractor 3 passes through the cylinder of power drive unit 6
The power of offer makes test device of the present invention be placed in vacuum environment, due to pressure difference (upper gap between support plate 1 and lower support plate 2
Interior pressure is more than the pressure of upper support plate 1 and the external vacuum environment of lower support plate 2), the air meeting between upper support plate 1 and lower support plate 2
The gap between support plate 1 and lower support plate 2 is run out of, so that vacuum state is formed between upper support plate 1 and lower support plate 2, so that
FPC is accurately tightly bonded together with sensor function piece.
Wherein, the lower surface of upper support plate 1 is provided with multiple limited posts 12, and the lower upper surface of support plate 2 is provided with multiple and limited post 12
The stopper slot 22 of matching, in vacuum engagement, each limited post 12 can be sticked into corresponding stopper slot 22, limited post 12
With the position-limiting action of stopper slot 22 staff's accurate observation can be made whether accurate with sensor function piece to FPC
It is tightly bonded together, so as to adjust the contraposition degree of accuracy of FPC and functional sheet at any time and to avoid its right
The test that position is carried out when inaccurate.
Upper support plate 1 and lower support plate 2 are made of transparent and flexible plastics, and upper support plate 1 connects with lower support plate 2 for flexibility
Touch.
The top of vacuum extractor 3 is provided with cover plate 4, and the junction (at closure) of vacuum extractor 3 and cover plate 4 is provided with sealing ring
5, sealing ring 5, which can play, further prevents vacuum extractor 3 and extraneous cross-ventilation, vacuum extractor 3 and power drive knot
Structure 6 connects, and power drive structure 6 is cylinder, and power drive structure 6 is used to provide power for vacuum extractor 3.
Wherein, groove I11 shape is T-shaped, and groove II21's is shaped as rectangle.
The test device of the single-layer multi-point capacitive touch screen of the present invention is applied to single-layer multi-point capacitive touch screen function
The test of piece, its concrete operating principle are as follows：
Before testing, test device is placed in vacuum extractor 3, upper support plate 1 and lower support plate 2 is fitted in one in order
Rise, fixed placement has the FPC of test, the groove I11 T-shaped (flexible circuitry of shape in the groove I11 of upper support plate 1
The part of plate sidewards is bonded with functional sheet to be detected), fixed placement needs test function piece in the groove II21 of lower support plate 2, on
In the stopper slot 22 of the lower support plate 2 of the insertion of limited post 12 of support plate 1, FPC and the mutually corresponding placement of functional sheet to be detected
(FPC with functional sheet to be detected be flexible contact), now go up together with support plate 1 is mutually closed with lower support plate 2, still
Still there is air between upper support plate 1 and lower support plate 2, with reference to not close；When starting test, start power drive unit 6, power drive
Device 6 provides power to vacuum extractor 3, and vacuum extractor 3 makes test device of the present invention be placed in vacuum environment, due to pressure
Strong poor (upper pressure between support plate 1 and lower support plate 2 in gap is more than the pressure of upper support plate 1 and the external vacuum environment of lower support plate 2),
Air between upper support plate 1 and lower support plate 2 can run out of the gap between support plate 1 and lower support plate 2, and then upper support plate 1 and download
Plate 2 is brought into close contact together, in the stopper slot 22 of the tightly embedded lower support plate 2 of the limited post 12 on upper support plate 1, FPC
Together with (part sidewards) is brought into close contact with functional sheet to be detected；The cover plate 4 of vacuum extractor 3 is opened, the present invention is tested
Device is placed in air, and now the pressure outside test device is more than the pressure between upper support plate 1 and lower support plate 2, therefore more enters
Together with one step makes support plate 1 be brought into close contact with lower support plate 2.
FPC be brought into close contact with functional sheet to be detected together with after, utilize FPC pair and its exactitude position
Functional sheet to be detected carry out subsequent detection (utilize the detection driving plate being connected with FPC to add functional sheet sensor
Set detection signal simultaneously receives feedback information, to reach the purpose to functional sheet functional test).
Above-mentioned embodiment is the preferable embodiment of the present invention, but embodiments of the present invention are not by the embodiment
Limitation, other any Spirit Essences without departing from the present invention with made under principle change, modification, replacement, combine, simplification,
Equivalent substitute mode is should be, is included within protection scope of the present invention.
