TECHNICAL FIELD

[0001] The patent belongs to the technical field of tray logistics conveying equipment, and particularly relates to a tray lifting and reversing device. BACKGROUND

[0002] In an automated production line, products or materials are usually placed in trays for transmission on a logistics line. For example, in a battery production line, batteries are placed in trays for transmission on a logistics line. For different battery production processes or between different devices, the trays need to be transmitted and transferred on different direction logistics lines and different height logistics lines. However, manual transfer is time-consuming and laborious, and has low work efficiency. Some existing tray lifting devices or lifting mechanisms solve the problem of tray transfer between different height upper and lower logistics lines, but cannot meet the needs of simultaneous transmission and transfer of trays on different direction logistics lines and different height logistics lines. Therefore, there is an urgent need to develop a new type of tray lifting and reversing device to solve the problems in the prior art. SUMMARY
