Background
The touch liquid crystal screen technology is a man-machine interaction input mode, and compared with the traditional keyboard and mouse input mode, the touch liquid crystal screen input is more visual, and is widely applied to electronic products such as flat panels. In order to ensure that the touch liquid crystal screen works normally, the touch liquid crystal screen needs to be checked before leaving the factory; during inspection, the touch liquid crystal screen is connected with the test circuit board through a flat cable, and after power-on, a tester needs to touch a screen operation interface on the liquid crystal screen by hand to inspect whether the touch liquid crystal screen is qualified.
It should be noted that, when the wiring operation between the touch liquid crystal screen and the test circuit board is performed, the tester will usually back-off the touch liquid crystal screen on the desktop, and since several interfaces between the touch liquid crystal screen and the test circuit board are all on the back of the touch liquid crystal screen, the vicinity of the interfaces is a metal plate with bare leakage, so as to avoid the risk of short circuit caused by direct contact between the test circuit board and the metal plate with bare leakage on the back of the touch liquid crystal screen, the touch liquid crystal screen needs to be isolated from the test circuit board by using an insulating isolation board.
After power-on, when a tester touches a screen operation interface on the liquid crystal screen by hand to test the quality of the touch liquid crystal screen, the tester is required to turn over the inverted touch liquid crystal screen and the test circuit board together, but the size of the test circuit board is small due to the large size of the touch liquid crystal screen, the insulating isolation board between the touch liquid crystal screen and the test circuit board is easy to fall off in the turning process, and the test circuit board is easy to directly contact with the metal plate with naked leakage on the back of the touch liquid crystal screen after falling off; meanwhile, in the overturning process, the touch screen can alarm due to the fact that the fingers of the testers touch the operation interface by mistake.
In order to solve the above problems, an ideal technical solution is always sought.

After the touch liquid crystal screen 5 is put into the tool, the liquid crystal screen positioning bracket 4 is rotated, and the angle rotating component indirectly drives the touch liquid crystal screen 5 to be tested to rotate to the back of the detection tool, so that a tester can conveniently connect the back of the liquid crystal screen with the test circuit board 7 through the flat cable 6;
after the wiring operation of the back surface of the liquid crystal screen is completed, the liquid crystal screen positioning support 4 is rotated again, the touch liquid crystal screen 5 to be detected is indirectly driven to rotate to the front surface of the detection tool through the angle rotating component, the front surface operation interface of a tester is facilitated, and the touch liquid crystal screen detection is carried out.
Therefore, when the back wiring operation and the front operation interface of the liquid crystal display are switched, the angle rotating component can effectively avoid the false alarm phenomenon caused by the false touch of fingers on the interface of the liquid crystal display, and the method is more in line with the human engineering concept.
Further, the angle rotating component is a turntable 3; in other specific embodiments, the angle rotating component may be another component capable of driving the liquid crystal display positioning bracket 4 to rotate by 360 degrees.
