The working principle of the invention is as follows:

a driving motor on the display screen loading device drives a transmission shaft to rotate, the display screen moves forwards through the transmission shaft, then a second driving motor on a display screen displacement assembly drives a movable sliding seat to move left and right through a driving belt, so that a first jacking cylinder is positioned at the position of the display screen, the first jacking cylinder drives a positioning optical shaft to position the display screen, then a third driving motor on a display screen turnover mechanism drives a turnover rotating shaft to rotate, so that a turnover suction plate is contacted with the display screen for suction, then a third driving motor continues to rotate the turnover rotating shaft, so that the turnover suction plate rotates to a horizontal position, the second jacking cylinder drives the whole turnover suction plate to move upwards, at the moment, a fourth driving motor on the display screen loading detection device drives a loading support seat to move to the turnover suction plate to be discharged, at the moment, the third jacking cylinder drives a detection positioning plate to move downwards, so that a suction nozzle display screen is grabbed and sucked on the detection positioning plate, then the fourth driving motor continues to drive the feeding supporting seat to move forwards, so that the detection positioning plate moves to the position above the large rotary table, then the display screen is conveyed to the display screen jacking assembly of the large rotary table, the display screen on the large rotary table is detected by the CCD detector, then the qualified display screen is conveyed to the position below the display screen rolling and labeling device by the large rotary table, at the moment, the sixth driving motor drives the label feeding assembly and the label cutting assembly to move downwards, then the feeding motor drives the feeding plate to rotate, the label moves to the labeling roller wheel group along the roller group, at the moment, the pressing cylinder drives the labeling driving column to rotate, the display screen is labeled by the labeling roller wheel, then the label which is labeled is completely labeled is cut off by the hot cutter, then the large rotary table continues to move to the blanking device, the blanking device blanks the labeled display screen, and when the CCD detector detects the unqualified display screen, the big rotary table can be directly rotated to the lower part of the blanking device, and blanking is carried out on unqualified display screens.
