Abstract

The present invention discloses a touch panel scribing detection device and a detection method thereof. The touch panel scribing detection device includes a loading platform, a scribing standardization unit, a test unit and a signal unit. The touch panel scribing detection device can provide an accurate scribing test path, so the accuracy and efficiency of manual test on a touch panel can be improved.

First claim

The invention claimed is:

1. A touch panel scribing detection device comprising:
a loading platform;
a scribing standardization unit movably arranged above the loading platform and configured to provide a standard scribing path for a touch panel to be tested;
a test unit configured to receive a touch signal of the touch panel to be tested, identifying an actual scribing path on the touch panel to be tested, and comparing the identified actual scribing path on the touch panel to be tested with the standard scribing path provided by the scribing standardization unit to judge the performance of the touch panel to be tested; and
a signal unit connected with the test unit, capable of being connected with the touch panel to be tested and a test signal input device, respectively, and configured to access a picture signal as a test signal and transmit the test signal to the touch panel to be tested, and transmit the touch signal of the touch panel to be tested to the test unit,
wherein a groove is arranged on an upper surface of the loading platform, the scribing standardization unit comprises a path plate, a track groove having the standard scribing path is arranged in the path plate, the path plate is movably arranged above the groove, and the touch panel to be tested is arranged in the groove and is located below the path plate, and
wherein the scribing standardization unit further comprises a fixing plate which is capable of being mutually engaged with the path plate, the fixing plate is movably arranged on the periphery of the groove, the size of the path plate is smaller than that of the groove, and the path plate is arranged on the fixing plate and is located at least above a central region of the groove.

2. The touch panel scribing detection device of claim 1 ,
wherein the fixing plate is of a frame-shaped structure with an opening on at least one side, the path plate has a plate-shaped structure with the track groove provided therein, upper surfaces of opposite inner frames of the fixing plate are lower than those of opposite outer frames, and the path plate is arranged on and absorbed to the upper surfaces of the opposite inner frames of the fixing plate with magnets.

3. The touch panel scribing detection device of claim 1 ,
wherein the fixing plate is connected with the loading platform by means of a slide rail or a hinge, and the path plate is detachably arranged above the fixing plate.

4. The touch panel scribing detection device of claim 1 ,
wherein the signal unit comprises a signal adapter plate, the signal adapter plate is provided with a plurality of interfaces, and each interface is configured to connect with the test signal input device to receive a picture signal for testing, or is configured to connect with the touch panel to be tested and outputting output the picture signal for testing to the touch panel to be tested, or is configured to connect with the test unit and output the touch signal of the touch panel to be tested to the test unit.

5. The touch panel scribing detection device of claim 4 ,
wherein the signal unit further comprises a signal connector, and the signal connector is configured to connect the signal adapter plate and the touch panel to be tested to transmit the picture signal or the touch signal between the signal adapter plate and the touch panel to be tested.

6. The touch panel scribing detection device of claim 5 ,
wherein the signal unit further comprises a pull-out module, the pull-out module is arranged above the loading platform and is provided with a pull-out groove, and a connector of the signal connector is inserted into the pull-out groove and is configured to connect with the touch panel to be tested.

7. The touch panel scribing detection device of claim 6 ,
wherein the pull-out module comprises a pull-out sheet or a semi-contact pressure head.

8. The touch panel scribing detection device of claim 1 ,
wherein the test unit comprises:
an identification module configured to identify the actual scribing path on the touch panel to be tested according to the received touch signal of the touch panel to be tested; and
a comparison module provided with a database corresponding to the standard scribing path therein, and configured to compare the identified actual scribing path on the touch panel to be tested with the standard scribing path provided by the scribing standardization unit to judge the performance of the touch panel to be tested.

9. The touch panel scribing detection device of claim 1 , further comprising a touch pen, wherein the touch pen is used by a tester to scribe on the touch panel to be tested according to the standard scribing path provided in the path plate, the touch pen comprises two contacts which are separately arranged in the same straight line and a connector for connecting the two contacts, and the two contacts are elastically connected.

10. The touch panel scribing detection device of claim 1 , further comprising a control button, wherein the control button is connected with the signal unit and the test unit, respectively, and is configured to start or close the test on the touch panel to be tested.

11. A touch panel scribing detection method, wherein the touch panel scribing detection device of claim 1 is used in the touch panel scribing detection method for detection, and in the touch panel scribing detection method, a replaceable scribing standardization unit having a function of fixing the touch panel to be tested and a function of standardizing a set path is adopted to manually scribe on the touch panel to be tested according to a set and replaceable standard scribing path and obtain a result indicating whether the performance of the touch panel to be tested is qualified.
