Industrial applicibility
With reference to Fig. 1, Fig. 2, the specific work process of the touch panel tester of the present embodiment is briefly described.
By touch panel 7 to be tested（Do not install cover board additional）It is fixed in the program-controlled plus microscope carrier 8 made an uproar on platform 1, and by touch-control
The communication interface of panel 7 is reliably connected with Panel connector 5.
By input unit 62 to threshold under the distance of fall upper threshold value, distance of fall of the input certified products of data processing centre 61
Value and output noise power.
Click starts to test, it is program-controlled plus make an uproar platform 1 in data handling under the control of the heart 61 output setting power noise, mould
Intend the background noise of product.Data processing centre 61 sends signal by Panel connector 5 to touch panel 7, controls touch surface
Plate 7 opens touch sensible channel, into test mode.Lifting gear 3 drives touch-control array of terminals 2 close to touch surface to be tested
Plate 7 after movement in place, sequentially falls according to the setting each touch-control terminal of sequential control, moves closer to touch panel to be tested
7.When the two apart from it is small to a certain extent when, touch panel 7 senses touch control operation, and output touching signals are transmitted to data processing
Center 61, while lifting gear 3 will also record the distance of fall of touch-control terminal, and pass to data processing centre 61.
In touch panel 7, multiple touch sensible channels are sequentially generated touching signals according to the whereabouts sequence of touch-control terminal and send out
It send to data processing centre 61.Data processing centre 61 is when receiving each touching signals, when recording touching signals generation,
The distance of fall of touch-control terminal corresponding to it, if the distance of fall of touch-control terminal is more than the distance of fall upper threshold value of setting,
It represents that the sensitivity of touch panel 7 is too low, is determined as defective products.If the distance of fall of touch-control terminal is less than the distance of fall of setting
Lower threshold value, then it represents that the sensitivity of touch panel 7 is excessively high, is determined as defective products.If touch-control terminal fall before or touch surface
Plate 7 does not generate touching signals according to the whereabouts of touch-control terminal sequence, then it represents that the poor anti jamming capability of touch panel 7 still judges
For defective products.If the distance of fall of touch-control terminal between the distance of fall lower threshold value of setting and distance of fall upper threshold value, and
Touch panel 7 is to be sequentially generated touching signals according to the whereabouts sequence of touch-control terminal, then it represents that the sensitivity of touch panel 7 is fitted
In, strong antijamming capability is determined as certified products.
It will judge to export on a display screen during fructufy by display unit 63, guidance is provided for reprocessing for defective products.
Before induction sensitivity test is carried out to touch panel 7, a large amount of qualified samples and failed test sample should be used（Packet
Include that sensitivity is too low and the excessively high sample of sensitivity）It repeatedly measures, under the support of mass data, determines the downthrow of certified products
From lower threshold value, distance of fall upper threshold value and noise power.
The touch panel tester of the utility model can be completed to sense touch panel in the case of not contact product
The test of sensitivity is avoided since product caused by contact scratches, can be excessively high according to actual product demand control sensitivity
Or the bad products that sensitivity is too low.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made in the essential scope of the utility model,
It should also belong to the protection scope of the utility model.
