The bearing table 14 in each touch screen testing device 1 is fixed on the touch screen testing device placing frame 21 in a screw and screw hole matching mode.
Because the touch screen can take place elastic deformation under high temperature or low temperature environment to change the pressure value of touch-sensitive screen testing arrangement 1 pressure head 1303, consequently need adjust the lead screw working stroke of lift drive 1301 in its touch-sensitive screen testing arrangement 1, rectify the pressure value of pressure head 1303. For example, when the touch screen is placed in a touch screen testing device 1 in a high and low temperature testing box 2, a click scribing test is performed in a high temperature environment, the touch screen is elastically deformed, and a pressure test value fed back by a pressure sensor 1302 is greater than a pressure preset value, the pressure control device 32 shortens a lead screw working stroke of a lifting driving device 1301 corresponding to the touch screen testing device 1, shortens a movement distance of a pressure head 1303 in a third direction, and further reduces pressure of the pressure head 1303 on the touch screen. When the pressure test value fed back by the pressure sensor 1302 is smaller than the pressure preset value, the pressure control device 32 increases the working stroke of the lead screw of the lifting driving device 1301 corresponding to the touch screen testing device 1, increases the movement distance of the pressure head 1303 in the third direction, and further increases the pressure of the pressure head 1303 on the touch screen, so that the influence on the scribing or clicking pressure testing accuracy of the touch screen when the touch screen is elastically deformed in a high-temperature environment can be prevented.

The pressure value 1, the pressure value 2 and the pressure value 3 may be the same or different, and each pressure value is set according to a test requirement, which is not limited herein.

Therefore, the pressure value of each pressure head can be adjusted according to the scribing pressure test requirement of the touch screen, so that scribing tests with different pressure sizes can be carried out on the touch screen.
When the scribing test is performed on the touch screen, the touch screen is fixed on the touch screen fixing jig 16, the pressure control device 32 controls the first direction movement mechanism 11 to drive the first lifting mechanism 131, the second lifting mechanism 132 and the third lifting mechanism 133 to move in the first direction on the touch screen according to the test requirement of the touch screen, and controls the second direction movement mechanism 12 to move linearly in the second direction, so that the first pressure head 1313, the second pressure head 1323 and the third pressure head 1333 are controlled to perform linear or oblique scribing at different positions of the touch screen, and meanwhile, the pressure values of the first pressure head 1313, the second pressure head 1323 and the third pressure head 1333 can be controlled, so that each pressure head can perform scribing at different positions of the touch screen with different pressure values.
The pressure control device 32 can control the pressure value of the pressure head 1303 on the touch screen in the lifting mechanism corresponding to each touch screen testing device 1, so that the multiple touch screens can be simultaneously clicked or scribed in a high-temperature or low-temperature environment, the different positions of each touch screen can be clicked or scribed with different pressures, and the testing efficiency is high. The pressure control device 32 can adjust the clicking or scribing pressure values of the touch screens under the high-temperature or low-temperature environment, so that the touch screens are prevented from being deformed under the high-temperature or low-temperature environment, the clicking or scribing test pressure values of the touch screens are inaccurate, and the clicking or scribing test precision of each touch screen is improved.
The invention provides a high and low temperature test method for a touch screen, which comprises the following steps:

In the step 2, if the temperature test value fed back by the temperature sensor 24 deviates from the preset temperature value, the introduction amount of the high-temperature or low-temperature gas is adjusted until the temperature inside the box body of the high-temperature and low-temperature test box 2 is consistent with the preset temperature value.
And 3, the pressure control device 32 controls the pressure head 1303 of each touch screen testing device 1 to perform multi-point click or scribing test on the touch screen to be tested according to a preset program.
In the step 3, if the touch screen to be tested deforms in the high and low temperature environment, and a deviation occurs between the pressure value fed back by the pressure sensor 1302 and the preset pressure value, the pressure control device 32 controls the working stroke of the lead screw of the lifting driving device 1301 of the corresponding touch screen testing device 1 according to the pressure deviation value, adjusts the movement distance of the pressure head 1303 in the third direction, and changes the pressure of the pressure head 1303 on the touch screen until the pressure value fed back by the pressure sensor 1302 is consistent with the preset pressure value.
