The mounting plate 191 drives the fixed rod 195 and the cleaning block 192 to move left. The fixed rod 195 moves left and slides in the straight hole plate 196. When the fixed rod 195 moves left and contacts the inclined surface of the straight hole plate 196, the straight hole plate 196 drives the fixed rod 195 to move upward, and the fixed rod 195 drives the mounting plate 191 to move upward. The reset spring 197 is stretched, and the mounting plate 191 drives the cleaning block 192 to move upward. The cleaning block 192 moves left and moves upward to contact the friction member after use. 13 contact, close the electric push rod 194, start the servo motor 193, the servo motor 193 drives the cleaning block 192 to rotate through the synchronous belt assembly, the cleaning block 192 rotates to remove the debris attached to the friction member 13, when the debris on the friction member 13 is cleaned up, start the electric push rod 194 to drive the movable frame 19 to move right and reset, the movable frame 19 drives the cleaning block 192 and the fixed rod 195 to move right through the mounting plate 191, the slotted hole plate 196 drives the fixed rod 195 moving rightward to move downward, the fixed rod 195 drives the mounting plate 191 to move downward, the reset spring 197 is reset, the mounting plate 191 drives the cleaning block 192 to move downward, the cleaning block 192 moves downward and moves to the right to break away from the friction member 13, after the cleaning block 192 is reset, close the electric push rod 194, and repeat this process to remove all the debris attached to the friction members 13. In this way, a large amount of debris adhering to the friction member 13 can be prevented from affecting the subsequent anti-friction performance test of the touch screen, thereby improving the accuracy of the anti-friction performance test of the touch screen.

[0044] See also Fig.13 As shown, the touch screen anti-friction performance detection device also includes an observation window 20, and the left sides of the front and rear sides of the box body 1 are fixedly connected with the observation window 20.
