Problems solved by technology

[0002] At present, with the multi-functionalization of mobile phones, touch-type mobile phones are more and more widely used, and touch-type multi-functional mobile phones require relatively high viscosity strength of mobile phone TP , it is necessary to test the viscosity of the TP of the mobile phone. Before the multi-functional mobile phone did not test the reliability of the TP paste, the user used it for a long time. The viscosity of the TP of the mobile phone is not up to the standard, and the TP will be generated when the customer uses it. Warping, leading to defects such as graying of the display screen and TP failure

Embodiment 1

[0030] Embodiment one A method for testing the sticking reliability of a mobile phone TP touch screen, comprising the following steps:

[0031] A), fix the mobile phone on the clamping device of the test device for testing the sticking reliability of the TP touch screen of the mobile phone of the present invention;

[0032] B), using the suction pull device of the test device for testing the sticking reliability of the mobile phone TP touch screen of the present invention, apply a gradually larger suction pull on the surface of the mobile phone TP touch screen to carry out the outward suction test; the pull gradually increases from 0, Stop after 5kg;

[0033] C) Detect the TP touch screen of the mobile phone after the suction pull test. If the edge of the TP touch screen of the mobile phone exceeds the frame of the mobile phone case, it is a defective product, and the edge of the TP touch screen of the mobile phone does not exceed the frame of the mobile phone case. It is a ...

Embodiment 2

[0034] Embodiment two A method for testing the sticking reliability of a mobile phone TP touch screen, comprising the following steps:

[0035] A), fix the mobile phone on the clamping device of the test device for testing the sticking reliability of the TP touch screen of the mobile phone of the present invention;

[0036] B), using the suction pull device of the test device for testing the sticking reliability of the mobile phone TP touch screen of the present invention, apply a gradually larger suction pull on the surface of the mobile phone TP touch screen to carry out the outward suction test; the pull gradually increases from 0, Stop until 4kg;

[0037] C) Detect the TP touch screen of the mobile phone after the suction pull test. If the edge of the TP touch screen of the mobile phone exceeds the frame of the mobile phone case, it is a defective product, and the edge of the TP touch screen of the mobile phone does not exceed the frame of the mobile phone case. It is a ...

Embodiment 3

[0038] Embodiment Three A method for testing the sticking reliability of a mobile phone TP touch screen, comprising the following steps:

[0039]A), fix the mobile phone on the clamping device of the test device for testing the sticking reliability of the mobile phone TP touch screen of the present invention;

[0040] B), using the suction pull device of the test device for testing the sticking reliability of the mobile phone TP touch screen of the present invention, apply a gradually larger suction pull on the surface of the mobile phone TP touch screen to carry out the outward suction test; the pull gradually increases from 0, Stop after 3kg;

[0041] C) Detect the TP touch screen of the mobile phone after the suction pull test. If the edge of the TP touch screen of the mobile phone exceeds the frame of the mobile phone case, it is a defective product, and the edge of the TP touch screen of the mobile phone does not exceed the frame of the mobile phone case. It is a good p...

Abstract

The invention discloses a device for testing the adhesion reliability of a mobile phone TP touch screen. The device for testing the adhesion reliability of the mobile phone TP touch screen comprises a test base, wherein an adjusting base plate is arranged on the rear side of the test base; a clamping device for clamping a mobile phone is arranged on the upper end surface of the test base; a tension device capable of moving up and down is arranged on the adjusting base. A method for testing the adhesion reliability of the mobile phone TP touch screen mainly comprises the following steps: suspending and fixing the mobile phone in the state without stress on four sides by using the device for testing the adhesion reliability of the mobile phone TP touch screen, then drawing TP by means of a push-pull gauge and a sucking disc to test the adhesion reliability of the TP, and determining that the TP is unqualified if the drawn TP is higher than a mobile phone framework, otherwise, determining that the TP is qualified if the TP is lower than the framework.

Description

technical field [0001] The invention relates to a sticking reliability testing technology of a TP touch screen of a mobile phone, in particular to a device and a method for testing the sticking reliability of a TP touch screen of a mobile phone. Background technique [0002] At present, with the multi-functionalization of mobile phones, touch-type mobile phones are more and more widely used. Touch-type multi-function mobile phones have relatively high requirements for the viscosity strength of mobile phone TP, and it is necessary to test the viscosity of mobile phone TP. Without testing the sticking reliability of the TP, the viscosity of the mobile phone TP is not up to the standard during the long-term use of the user, and the TP will warp when the customer uses it, which will lead to defects such as dust entering the display screen and TP failure. Contents of the invention [0003] The object of the present invention is to aim at the above-mentioned defects of the prio...
