[0032] Please refer to Figure 5, the turnover table 33 is further provided with two clamping jaws 35 driven by a sixth motor 34. In the embodiment, a gear is connected to the output end of the sixth motor 34, and the gear is engaged with two racks, both of which are installed on the turnover table 33 (the racks are prior art, and thus the structure thereof will not be described here again). The two racks are respectively connected with the two clamping jaws 35, so that the sixth motor 34 drives the two clamping jaws 35 to move in the same direction or opposite directions when the sixth motor 34 operates.

[0034] Please refer to Figures 1 to 6In the operation of this utility model, the multi-layer stacked trays 14 are first placed on the receiving platform 13. The tray lifting assembly 12 drives the receiving platform 13 and the multi-layer trays 14 (and the digital tubes on them) to rise, so that the uppermost tray 14 moves to the same height as the gantry 157. At this time, the first motor 152 drives the first belt 153 to move, which drives the two first supports 156 to move in the same direction, so that the gantry 157 moves towards the side where the second pushing structure 16 is located, thereby pushing the uppermost tray 14 closer to the second pushing structure 16, so that the first row of digital tubes on the tray 14 can fall onto the conveyor belt 18. Then, the second motor 161 drives the second belt 162 to move, so that the second support 164 drives the pusher plate 165 to push the digital tubes that have fallen on the conveyor belt 18 onto the first conveyor belt 23 (then the gantry 157 continues to run, pushing the digital tubes that have fallen on the conveyor belt 18 onto the first conveyor belt 23). Rows of digital tubes are gradually fed to conveyor belt 18); the third motor 22 drives the first conveyor belt 23 to run. When the digital tubes are running on the first conveyor belt 23, the fourth motor 24 needs to run to drive the rack 25 to move, so that the limiting plate 26 moves above the first conveyor belt 23 to a suitable position to straighten the digital tubes moving on the first conveyor belt 23 and prevent them from being arranged in a disorderly manner; then the digital tubes are sent to the end of the first conveyor belt 23, and the fifth motor 32 drives the tilting table 33 to tilt, so that the sixth motor 34 and the two grippers 35 move to the end of the first conveyor belt 23 to receive them. During reception, the digital tubes are placed between the two grippers 35. The sixth motor 34 drives the two grippers 35 to move closer to each other to clamp the digital tubes. Then the fifth motor 32 drives the tilting table 33, the sixth motor 34 and the two grippers 35 to rotate 180° (see appendix). Figure 4 and attached Figure 5 (as shown in the image), the digital tube is moved to the position of the product conveyor block 54; at this time, the seventh motor 52 is driven to run, driving the second conveyor belt 53 and the product conveyor block 54 on it to run. The digital tube moves with the product conveyor block 54 to the bottom of the CCD vision inspection device 4 and is inspected by the CCD vision inspection device 4 (the technical principle of the CCD vision inspection device 4 is existing technology and will not be described in detail here); after the inspection is completed, the digital tube is held by the robot arm 55 and sent to the end of the second conveyor belt 53, and then received by the third conveyor belt 62 and sent to the cavity of the collection box 61, completing the inspection process of the digital tube.
