[0035] Working principle:

[0036] When the gravity center of the goods is offset on the tray, the tray will have a tendency to overturn, at this time, since the channel plate locking curve and the rotating center of the yoke coincide, the yoke only bears the radial force and does not bear the external force to drive the yoke to rotate, so that the driving assembly can make the tray reliably self-lock in the horizontal state without being powered, the schematic diagram is shown in the attached Figure 2 and the attached Figure 3 , in the figure, G is the gravity of the goods, F is the external force for limiting the tray from overturning, O1 is the overturning center of the tray, and O2 is the rotating center of the yoke. The yoke mainly comprises a yoke rotating shaft, a triangular plate, a driving roller one, a driving roller two and an auxiliary roller three, the structural schematic diagram is shown in the attached Figure 4 . The channel plate structural schematic diagram is shown in the attached Figure 5 .

[0037] When the tray is turned to the side, the rubber pad limits the further turning of the tray, and the reverse impact will occur at the moment of limiting, the tray has a tendency of reverse turning, at this time the auxiliary roller three on the fork contacts the channel plate to limit the reverse turning of the tray, so that the tray can realize the self-locking state after turning to the position, the schematic diagram is shown in the accompanying Figure 6 , F1 is the external force limiting the further turning of the tray, and F2 is the external force limiting the reverse turning of the tray.

[0038] The working channel of the driving roller adopts an "eight" type down-lying curved surface design, which can make the driving assembly always maintain a large force arm during the whole turning process, provide sufficient torque for the turning process of the tray, and thus realize the low-power large-load work of the driving assembly, the turning power and force arm schematic diagram is shown in the accompanying Figure 7 , F is the driving force suffered by the tray during turning, and L is the force arm.

[0039] If the working channel is designed as an up-lying curved surface, the action line of the turning power will be close to the center of the tray turning, at this time the force arm is small, which is easy to cause insufficient turning torque of the tray, the turning power and force arm schematic diagram is shown in the accompanying Figure 8 , F ， is the driving force suffered by the tray during turning, and L ， is the force arm.

[0040] The contact form of the main tray and the driven tray is optimized from sliding friction to rolling friction, when the main tray and the driven tray have relative motion, the rolling bearing can roll on the driven tray, avoiding the friction noise generated when the main tray and the driven tray have relative motion, realizing the low-noise operation of the bearing tray, the contact form schematic diagram is shown in the accompanying Figure 9 and Figure 10 .

[0041] Whenever the device is powered on again, it is necessary to find the origin first, and after the origin finding is completed, the tray can be normally turned, the working process schematic diagram is shown in the accompanying Figure 11 .

[0042] Method one: after the device is powered on, if the tray is in the horizontal position, it will be detected by the horizontal detector, the displacement value of the driving assembly is set to M (M is obtained in advance by testing), and the motor back to origin completion signal is set to 1.

[0043] Method two: after the device is powered on, if the tray is not in the horizontal position, it will not be detected by the horizontal detector, the driving assembly will drive the tray to rotate in the opposite direction at low speed, while monitoring the output torque, when the driving assembly rotates to the structural limit, the torque output will reach the set torque threshold, after the torque output lasts for a set time, the driving assembly will stop the rotation instruction, the current position is taken as the origin, the displacement value of the driving assembly is set to 0, the set position value is 0, and the driving assembly back to origin completion signal is set to 1.
