[0032] Among them, the structure of the panel carrier can be as follows Figure 4 As shown, it is a container for carrying panels, generally an openable box structure, in which panels are stored, such as PCB panels, etc. The shape of the panel carrier is adapted to the U-shaped area of ​​the anti-collision structure, so that the panel carrier can be placed in the anti-collision structure, and can be blocked by a retractable material stopper 1, so that the automatic transport vehicle can transport the panel carrier.

[0033] It can be seen that in this embodiment, a "U"-shaped anti-collision structure is provided on the guide vehicle body, which can be used to prevent collisions on both sides of the panel carrier, and a retractable material stopper 1 is also provided in the "U"-shaped structure to prevent the material from dumping when the automatic conveyor vehicle brakes suddenly during transportation, thereby realizing the transportation of the panel carrier by the automatic conveyor vehicle, improving the circulation efficiency and reducing the labor cost of manual pushing.
