Referring to fig. 1, the present invention provides a touch screen monitoring system, including: support frame 1, clamp plate 2, camera and control module. The pressing plate 2 is a transparent hard plate.
The pressing plate 2 is horizontally arranged on the supporting frame 1, a groove 20 is formed in the lower surface of the pressing plate 2, and the groove 20 forms a continuous curve shape on the lower surface of the pressing plate 2 to serve as a detection curve. An expansion pipe 3 is arranged in the groove 20, one end of the expansion pipe 3 is connected with an air supply device 4, and the other end is connected with a vacuum pump 5. The expansion pipe 3 is a transparent hose.
Still install splint 6 on the support frame 1, splint 6 are located clamp plate 2 below, and 6 upper surfaces of splint are equipped with the detection groove that is used for placing touch-sensitive screen A. When the touch screen A is placed in the detection groove, the projection of the groove 20 on the horizontal plane is positioned on the touch screen A and covers the full screen of the touch screen A. And, in the detection process, the expansion pipe 3 in the inflation state expands out of the pressure plate 2 and abuts against the touch screen A.
Specifically, in the present embodiment, the clamp plate 6 is vertically movably mounted on the supporting frame 1, and during the detection process, the clamp plate 6 is located at the upper end of the movement track. Specifically, when the clamping plate 6 moves downwards, the clamping plate 6 is far away from the pressing plate 2, so that the touch screen A is convenient to mount; after the touch screen A is installed in the detection groove, the clamping plate 6 is moved upwards, so that the clamping plate 6 and the pressing plate 2 can be conveniently matched.
In this embodiment, before the detection, through vacuum pump 5 with expansion pipe 3 evacuation for expansion pipe 3 is accomodate in recess 20 completely, thereby splint 6 carries touch-sensitive screen A and moves the back up, can make splint 6 and clamp plate 2 laminate. And then, starting detection, wherein in the detection process, firstly, the air supply device 4 is started, the expansion pipe 3 is inflated to expand the expansion pipe 3, the expansion pipe 3 is extruded out of the groove 20 to extrude the touch screen A to form a touch screen pressing action, and the touch screen generates a touch signal.
In the embodiment, the expansion pipe 3 is sequentially pressed on the touch screen in the section-by-section expansion process after being vacuumized and recharged, so that the continuity of curves drawn on the touch screen by inflating the expansion pipe 3 is ensured.
The camera is installed on support frame 1 and is located clamp plate 2 top, and the camera is used for shooing touch-sensitive screen A on splint 6. Therefore, in the detection process, the drawing track formed by the expansion of the expansion pipe 3 on the touch screen can be shot and recorded through the camera. In the embodiment, the pressing plate 2 and the expansion pipe 3 are both made of colorless materials so as to improve the definition of images shot by the camera.
