Automatic offline test scheme for touch screen function

Abstract

The invention relates to touch screen function test, and particularly relates to an automatic offline test scheme for a touch screen function, which comprises a voltage-stabilizing power supply, a key switch, a controller, a solenoid valve, a cylinder, a pressing head, and a touch screen offline tester, wherein the power supply voltage of the voltage-stabilizing power supply is 12 V; the key switch (SW) is a three-pin self reset-type switch; the solenoid valve has a working voltage of 12 V and a rated power of 0.3 W; and the working voltage of the controller is 5 V, and voltage reduction on DC 12 V through a voltage reduction circuit of the controller is carried out for realizing power supply. No test software needs to be loaded in a PC, a test file is stored to the controller touch screen offline tester, and offline test can be realized; after the controller detects the switch SW is pressed, a time delay state set by a program is entered; at the same time, the controller brakes the solenoid valve to brake the cylinder through the gas, an M4 hexagon socket head cap screw is used between the pressing head and the cylinder for locking, the pressing head presses downwardly to be connected with the touch screen, and the touch screen offline tester reads firmware information of the to-be-tested touch screen; and the controller ends a delay state, driving signals are generated, the touch screen offline tester carries out test actions on the touch screen, and automatic test is thus realized.

Description

technical field [0001] The invention relates to the test of the touch screen function, in particular to an automatic off-line test scheme of the touch screen function. Background technique [0002] In the current touch screen factory, the touch screen function is tested by manually clicking the mouse driver after connecting the product to the fixture. This traditional operation method requires a PC to work, and the PC is not only bulky, has many wires, but also has low work efficiency. The stability of the production process is relatively poor. If it is still a manual operation, the efficiency is even lower , but also affect the company's image. Therefore, a stable and efficient offline automated testing solution is the goal pursued by major manufacturers. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an automatic off-line test solution for touch screen functions, which can ensure the stability of the ...
