[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the AGV robot with a visual target recognition mechanism not only realizes the function of facilitating target recognition and unloading, but also realizes the function of facilitating position limiting and clamping;

[0013] (1) By providing a protective frame, an identification plate, a visual identification module, a protective plate and an elastic rod, the visual identification module on the protective frame facilitates the AGV robot body to identify the target during the handling process. The two sets of visual identification modules at different heights can improve the efficiency of the AGV robot body in target identification.

[0014] (2) By providing a placement plate, a reserved slide groove, a ball bearing, a screw guide rail, a second motor and a screw guide sleeve, the goods can be transported and delivered by being piled on the placement plate. When unloading, the goods can be unloaded from the rear end of the placement plate. During the unloading process, the second motor drives the screw guide rail to rotate, and the screw guide rail drives the placement plate to move above the AGV robot body. The placement plate moves to the rear end to facilitate the staff to quickly unload the goods. This structure realizes the function of facilitating unloading and loading.

[0015] (3) By providing a movable seat, a limit plate, a clamping plate, a clamping cylinder and a first motor, the limit plate can limit the goods placed on the top of the AGV robot body. After the goods are placed on the placement plate of the AGV robot body, the first motor drives the limit plate to be perpendicular to the AGV robot body to protect the goods, and then starts the clamping cylinder. The clamping cylinder pushes the clamping plate to limit and clamp the goods, thereby improving the stability of cargo transportation. This structure realizes the function of facilitating limit clamping. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Specifically, if Figure 1 and Figure 3 As shown, the goods can be transported and conveyed by piling them on the placement plate 3.
