[0021] In a further specific implementation of this embodiment:

[0022] During testing, the screen is placed on the placement post 8, and the screen size is scanned by the scanning probe 11. This size information is then transmitted to the microcontroller 10, which in turn transmits the information to the linear motor 5. The linear motor 5 moves to a set position corresponding to the size, and then the telescopic rod 6 extends to the set position, causing the screen to detach from the placement post 8. The vacuum suction cup 7 then contacts the bottom surface of the screen and is activated to hold the screen in place. The linear motor 5 then moves the screen left and right within the testing area of ​​the testing body 1 to perform the testing. After the testing is completed, the linear motor 5 returns to its initial position, the vacuum suction cup 7 detaches from the screen, the telescopic rod 6 resets, and the linear motor 5 resets, completing the screen testing.
