The outer surfaces of the first test rod 2010, the second test rod 2012 and the third test rod 2015 are all soft rubber layers for protecting the flexible touch screen.
The initial positions of the induction transmitter 204 and the induction receiver 205 are on the same horizontal line.
A worker can manually operate or use an external conveying device to position the flexible touch screen right above the two pressure rods 1010, then the external conveying device is controlled to place the flexible touch screen on the two bearing rods 107, then the four first electric telescopic pieces 108 are controlled to operate simultaneously, the four first electric telescopic pieces 108 respectively drive one supporting block 109 to move downwards, at the moment, the two pressure rods 1010 move downwards along with the four supporting blocks 109 and position the flexible touch screen on the two bearing rods 107, and meanwhile, the four second elastic pieces 1011 effectively realize a buffering function, so that the situation that the surface of the flexible touch screen is directly damaged due to the fact that the two pressure rods 1010 are directly pressed down is avoided; meanwhile, the centers of the flexible touch screens are positioned right above the third test rod 2015 under the action of the elastic forces of the four first elastic pieces 104, so that the flexible touch screens are positioned rightly and prevented from moving transversely.
