The sensor camera 6b is connected to a visual recognition system and can perform visual analysis on the white paper passing below to process it into a control electrical signal to control the suction device 5 to suck the unqualified white paper.

[0032] The specific implementation process is as follows:

[0033] When the automatic paper selection device needs to be used, it is first installed at the position where it needs to be used, and the position needs to be horizontal. Then, the white paper to be sorted is introduced from the left end of the conveyor belt 2, and the driving device body 3 is started to drive the conveyor belt 2 to start conveying it;

[0035] Next, when the white paper passes under the sensor camera 6b, it is analyzed and detected to detect the position of the unqualified white paper on the conveyor belt, and the third motor 532 is started to start working. The third motor 532 rotates with the threaded rod 536, and the threaded rod 536 moves relative to the two sets of displacement members 537 to move to the corresponding position of the unqualified white paper. At this time, the cylinder 5310 is started to start working, and the push-out plate 534 is pushed, so that the suction head 535 can contact the white paper board to suck it up, and then the first motor 5b is started to work, and the rotating cylinder 52 is rotated, so that the sucked white paper is moved to the upper right corner of the collection box 6 and put down, and can be collected by the collection box 6. There are four groups of adjustment suction mechanisms in the suction device 5, which can perform high-efficiency circulation work.
