[0026] Please continue reading Figure 1 The test component 200 is connected to the test frame 100 and includes a touch chip 210 embedded in the center of the test frame 100. A plurality of communication line pads 220 are connected to the upper outer side of the test frame 100. A touch screen interface 230 is provided at the lower outer side of the test frame 100. The communication line pads 220 and the touch screen interface 230 are both connected to the touch chip 210, and RST and GND are introduced to the two ends of the external button switch through external wires;

[0027] The plurality of communication line pads 220 are linearly and equidistantly arranged from left to right along the outer side of the test frame 100, and the communication line pads 220 are connected to the test frame 100;

[0028] Example:

[0029] If the touch screen is directly connected Figure 1After the test of the adapter board, since the touch chip 210 on the adapter board is always in the power-on state and cannot be actively reset, when the next touch screen is connected, it cannot be automatically tested, and it is necessary to manually click the test software with the mouse to test it, which is very time-consuming. Therefore, a button switch is added between the RST and GND communication line pads 220. When the next touch screen is connected, press the button switch to short-circuit RST and GND. After pressing for 1 second, the IC will perform a reset. After the reset, the touch screen test software will automatically test;

[0030] Please continue reading Figure 1-2 To facilitate auxiliary fixation of the test frame 100, both ends of the test frame 100 are connected to connecting components 300, and the connecting components 300 include connecting frames 310 that are clamped to both ends of the test frame 100. Both sides of the connecting frame 310 are connected to tension springs 311. The ends of the tension springs 311 are connected to supports 320. The bottom of the supports 320 is connected to angle brackets 321. The angle brackets 321 are threaded with locking bolts 330. The ends of the locking bolts 330 are connected to the pressure plates 331 corresponding to the inner sides of the angle brackets 321.

[0031] action:

[0032] Before testing, the two sets of connecting brackets 310 are clamped on both ends of the test frame 100, and the angle brackets 321 are stretched. The two sets of angle brackets 321 are clamped on the base surface (which can be a table or a test bench) by the action of the tension spring 311. Then, the locking mechanism 330 is rotated to drive the pressure plate 331 to stabilize the entire device on the base surface.

[0033] Working principle: When using this utility model, after the previous touch screen is tested, a button switch is added between the RST and GND communication line pads 220. When the next touch screen is connected, the button switch is pressed to short-circuit RST and GND. After pressing for 1 second, the IC will reset. After resetting, the touch screen test software will automatically test to improve test efficiency.
