Fixing piece 200 is installed in the mounting base 203;
Rotary position-limit mechanism is provided between the rotating member 201 and the fixing piece 200, the rotary position-limit mechanism is used In the rotational angle for limiting the rotating member 201;
The lifting device is installed on the rotating member 201;
The image acquisition device includes bindiny mechanism and image collection mechanism;
The image collection mechanism is installed on the top of the lifting device by the bindiny mechanism;
The image collection mechanism can vertically be swung by the bindiny mechanism;
First transmission mechanism is installed on the lifting device end;
First transmission mechanism can drive video acquisition device to swing laterally in a certain range;
The transport vehicle includes moveable transport vehicle chassis structure;
The rotating device is mounted on the transport vehicle chassis structure.
The AGV material transfer trolley provided by the utility model, is moved to by transport vehicle and requires position, pass through rotation The rotating member of device drives lifting device and the outstanding rotation of image acquisition device.Lifting device can drive first transmission mechanism and Video acquisition device lifting.Image acquisition device can be preliminary to the carry out such as surrounding image collection.Since rotating device is provided with Rotary position-limit mechanism can limit rotating member, will not infinite rotational, fast and easy adjust turned position, while again make turn Moving part can be rotated freely locally, it might even be possible to reach 360 ° of rotation.Therefore, can be made by rotating image collection mechanism and Video acquisition device is rotated to suitable position.Simultaneously as the image collection mechanism can vertically be swung, therefore, can adjust Save suitable acquisition angles.So as to carry out preliminary acquisition so that image collection mechanism reaches optimal acquisition position, judge Preliminary direction.In turn, video acquisition device hoisting depth can be made by lifting device, expands the acquisition visual field, is carried out preliminary Positioning.After Primary Location, video acquisition device decline, at the same time it can also lateral in a certain range by the first transmission mechanism It swings, can choose suitable acquisition position, accurately to be acquired and be positioned.
As shown in Fig. 2 to Figure 10, in the optinal plan of the present embodiment, the rotary position-limit mechanism includes fixed locating part 100, swing component 101 and rotary stopper part 102;
The fixed locating part 100 is fixed on fixing piece 200;The fixed locating part 100 is provided with retention bead 1001;
The rotary stopper part 102 is fixed on the rotating member 201 reciprocally rotated, and the rotary stopper part 102 includes Two limited blocks 1021;
The swing component 101 is located between two limited blocks 1021, the swing component 101 and the rotary stopper Part 102 or the rotating member 201 are hinged, keep the swing component 101 swingable;
When the rotating member 201 be located at rotation initial position when, the two sides of the swing component 101 respectively with the limit convex Play 1001 and the abutting of one of limited block 1021;
When the rotating member 201 turns to maximum rotation angle position, the two sides of the swing component 101 respectively with it is described Retention bead 1001 and another limited block 1021 abut;The maximum rotation angle of the rotating member 201 is not less than 360 °;
