The first code scanning assembly 15 realizes the overall code scanning of the pallet group of multiple pallets stacked on one body, the second code scanning assembly 16 realizes the code scanning of a single pallet, and the third code scanning assembly 17 realizes the code scanning of a single screen to be tested. Scanning and detecting by three code scanning assemblies can effectively avoid misdetection of wrong code products, thereby improving the accuracy of the overall screen detection system, while avoiding wrong code products from entering the detection program, and improving detection efficiency.

[0027] A visual docking component 21 is provided at the end of the docking assembly line 13, and the visual docking component 21 performs visual photography correction on the screen to be tested that has completed three scans and is retained, so as to facilitate the loading unit to grab the screen to be tested.

[0028] Generally, the feeding unit is also provided with a discharge robot 22 for moving the wrong code tray or the wrong code screen determined by scanning by the first scanning component 15, the second scanning component 16, and the third scanning component 17 out of the feeding unit.

[0032] The specific working process of the feeding unit is as follows:

[0033] S1, the pallet group of multiple stacked pallets transported by an automatic logistics trolley or an overhead crane enters the inflow assembly line. When the pallet group moves to the inflow scanning position due to the braking action of the inflow assembly line, the first scanning component 15 scans the pallet.

[0034] S2, after completing the first code scanning process, the inflow assembly line continues to move the pallet group into the correction position, at which the clamping guide assembly 14 performs preliminary clamping positioning correction on the pallet group.

During the separation, the separation component 23 also performs a second positioning correction on the separated pallet, so as to facilitate the handling by the pallet robot 18. The pallet robot 18 sucks up the separated pallet and moves it to the lifting component 20 of the discharge assembly line 12 after a second scan confirmation by the second scanning component 16.

[0036] S4, the material picking robot 19 picks up the screen to be tested on the tray and places it on the mobile platform; preferably, the material picking robot 19 is provided with a visual positioning device, through which the tray is visually photographed with a wide field of view to determine the position of the screen to be tested on the tray, so as to correct the position and posture of the material picking robot 19, thereby achieving accurate grasping of the screen to be tested. The mobile platform is generally configured as a microporous ceramic platform, which is suitable for flexible screens to be tested; the mobile platform drives the screen to be tested to the docking scanning position, and the third scanning component 17 scans the screen to be tested for the third time at the docking scanning position. The discharge robot 22 arranged on the docking assembly line 13 excludes the screen to be tested that has been scanned incorrectly.

[0037] S5, after completing the third code scanning, the screen to be tested that is retained is moved to the position of the visual docking component 21 through the docking assembly line 13, and the visual docking component 21 performs visual photography correction on the screen to be tested.
