However, the existing robots cannot prevent materials from rolling while transporting quickly. During the transportation process, cylindrical materials roll and fall on the conveyor belt, affecting the transportation efficiency. If the materials are cylindrical glass products, they may be damaged seriously in severe cases.

The blocking door is used for blocking or releasing the materials placed on the conveyor belt 1; that is, the blocking door can block the materials to prevent them from detaching from the conveyor belt 1 during the movement of the mobile chassis 15, or release the materials to make them detach from the conveyor belt 1 when the mobile chassis 15 stops moving, or upload the materials to the conveyor belt 1 when the mobile chassis 15 stops moving.

[0030] The rolling prevention mechanism includes a plurality of rolling prevention plates, and the rolling prevention plates are located between the mobile chassis 15 and the conveyor belt 1. Strip-shaped protrusions are formed on the rolling prevention plates; in this embodiment, the rolling prevention plates are installed on a conveying support plate 16 arranged below the conveyor belt 1.

[0031] In this embodiment, the robot further includes a lifting mechanism. The blocking door is used for lifting in the height direction under the drive of the lifting mechanism, and the height direction refers to the direction perpendicular to the mobile chassis 15. In other embodiments of the present invention, the blocking door is hinged to one end of the conveyor belt 1 through a rotating shaft, and the rotating shaft is connected to the output end of the driving device. The blocking door is used for rotating around the rotating shaft under the drive of the driving device, that is, flipping outwards to open one end of the conveyor belt 1, or flipping upwards to block one end of the conveyor belt 1;

[0032] The robot further includes a driving device, and the driving device is used for driving the blocking door to lift or flip relative to the conveyor belt to realize that the blocking door blocks or releases the materials placed on the conveyor belt.
