[0003] In the prior art, there is a battery automatic flipping and loading and unloading device with announcement number CN219296506U, which includes: a conveying mechanism, a material moving mechanism arranged on one side of the conveying mechanism, and a flipping mechanism arranged on the other side of the conveying mechanism and corresponding to the material moving mechanism; the material moving mechanism is used to transfer materials between the conveying mechanism and the flipping mechanism, and the flipping mechanism is used to flip the materials. The structure of the flipping mechanism is not only simple in structure, but also convenient for maintenance and installation, and effectively saves costs; at the same time, through the mutual cooperation of the conveying mechanism, the material moving mechanism and the flipping mechanism, the battery is automatically flipped and loaded, and the battery is automatically switched between the horizontal state and the vertical state, meeting the battery state requirements of different process technologies, facilitating subsequent process operations, and significantly improving production efficiency; and solving the problem that manual flipping is time-consuming and labor-intensive, and has low production efficiency and cannot meet the current growing demand for production capacity.

[0004] However, although the existing loading and unloading device can well transport and transfer the workpiece when in use, it is not very effective in automatically reversing and leveling the workpiece when transporting the workpiece, and the buffering effect between the workpiece and the conveying roller is not very good when the workpiece is reversed and transported, so that when the suction cup separates the workpiece, the workpiece will collide with each other and produce noise. At the same time, the collision between the workpiece and the conveying roller will cause the workpiece to deviate, which reduces the efficiency of leveling and transporting the workpiece and does not meet people's use needs. For this reason, we propose an automatic reversing loading and unloading device. Summary of the Invention
