Although above-mentioned scheme can make the material be difficult for dropping to the production line and distribute the clearance between the dolly, it can not take the material from the goods shelves steadily to because of freely landing through gravity and lead to the material state unstable when transporting the material to the production line by the AGV dolly, be particularly unsuitable for the transportation of precision parts.

In order to solve the problems, the application provides a AGV is with plugging into moving and carrying device and material transfer car (buggy), and it can realize steadily plugging into between goods shelves and transfer chain and transport to can satisfy the not co-altitude needs of goods shelves and transfer chain, the commonality is higher.

Specifically, referring to fig. 1 to 3, an embodiment of the present invention provides a material transfer trolley 1, which may include an AGV body 10 and a transfer device 20 for AGV that is suitable for being correspondingly disposed on the AGV body 10, so as to pass through the AGV body 10 will the transfer device 20 for AGV for plugging transports to a position corresponding to the goods shelf 2 or the conveying line 3, so that the transfer device 20 for AGV for plugging can be followed the goods shelf 2 or the conveying line 3 is located to pick and place the material W. It can be understood that the material W mentioned in the present application may be implemented as, but not limited to, a box body for carrying parts, and may also be implemented as specific parts that need to be transported, which is not described in detail in the present application.

More specifically, as shown in fig. 1 and 3, the docking transfer device 20 for AGVs may include a carrier assembly 21, a lift platform 22, and a translation mechanism 23. The carrier assembly 21 includes a carrier platform 211 for carrying the material W and a transfer mechanism 212, and the transfer mechanism 212 is disposed on the carrier platform 211 for transferring the material W to and from the carrier platform 211. The lifting platform 22 is controlled to lift the carrier assembly 21 to adjust the height of the carrier platform 211. The translation mechanism 23 is correspondingly disposed between the lifting platform 22 and the loading platform 211, and is used for translating the loading platform 211 relative to the lifting platform 22 so as to extend the conveying mechanism 212 out of the lifting platform 22.

It should be noted that, as shown in fig. 2A, when the material W needs to be taken from the rack 2, the docking transfer device 20 for AGVs of the present application can first raise the loading platform 211 of the loading assembly 21 to the lateral lower side of the material W through the lifting platform 22, and then translate the loading platform 211 of the loading assembly 21 out of the lifting platform 22 through the translation mechanism 23, so that the conveying mechanism 212 is located right below the material W to contact the bottom of the material W, and further smoothly dock the material W from the rack 2 into the loading platform 211 through the conveying mechanism 212. Subsequently, as shown in fig. 2B, the carrier assembly 21 carrying the material W is translated back to the lifting platform 22 by the translation mechanism 23, and the carrier assembly 21 carrying the material W is lowered to the lowest point by the lifting platform 22, so as to ensure smooth transportation of the material transfer trolley 1. It is understood that in other examples of the present application, after the translation mechanism 23 translates the conveying mechanism 212 to the position right below the material W, the carrier assembly 21 may be further lifted by the lifting platform 22, so that the conveying mechanism 212 is in close contact with the material W, so as to ensure that the material W is conveyed to the central area of the carrier platform 211 by the conveying mechanism 212.

Similarly, as shown in fig. 2C, when the material W needs to be placed on the conveying line 3, the docking transfer device 20 for AGVs of the present application can first lift the loading platform 211 of the loading module 21 to a position flush with the conveying line 3 by the lifting platform 22, and then translate the loading platform 211 of the loading module 21 out of the lifting platform 22 by the translation mechanism 23, so that the conveying mechanism 212 docks with the conveying line 3, and then smoothly dock the material W from the loading platform 211 into the conveying line 3 by the conveying mechanism 212. It will be appreciated that after transferring the material W to the conveyor line 3, the translation mechanism 23 may retract the carrier module 21 and the lifting platform 22 lowers the carrier module 21 to the lowest point for rapid movement to the pick-and-place station.

Thus, when the translation motor 231 drives the translation lead screw 232 to rotate, the lead screw nut 233 is pushed by the translation lead screw 232 to drive the object stage 211 to perform a translation motion, so that the translation mechanism 23 translates the object stage assembly 21 relative to the lifting platform 22 is realized.

Preferably, as shown in fig. 1 and 3, the translation mechanism 23 further includes a telescopic rail 234, wherein the telescopic rail 234 includes a first rail 2341 fixedly arranged on the lifting platform 22 and a second rail 2342 fixedly arranged on the carrier platform 211, and the second rail 2342 is slidably matched with the first rail 2341 to guide the translation direction of the carrier assembly 21 relative to the lifting platform 22 through the telescopic rail 234 and support the carrier platform 211 through the telescopic rail 234 to improve the carrying capacity of the carrier assembly 21. It can be understood that the first guide rail 2341 and the second guide rail 2342 may be matched in an inserting or embedding manner, as long as the telescopic guide rail 234 is limited to be telescopic along the axial direction of the translation screw 232 while the two are ensured to be slidable relative to each other, and details of the telescopic guide rail 234 are not repeated herein.

Alternatively, as shown in fig. 1 and 3, the first rail 2341 of the telescopic rail 234 is fixedly mounted on the upper surface of the lifting plate 222 of the lifting platform 22, and the second rail 2342 of the telescopic rail 234 is fixedly mounted on the lower surface of the carrier platform 211.
