Jacking positioning device and material transfer system

The utility model relates to the technical field of material transfer, in particular to a jacking and positioning device and a material transfer system, and aims to solve the problem that the deviation of a box body of a battery pack easily exceeds the upper limit of allowable deviation after the box body is jacked and positioned along with an AGV (Automatic Guided Vehicle). In order to achieve the purpose, the jacking and positioning device comprises a rack and a lifting mechanism, a horizontal moving assembly is arranged at the top of a lifting component of the lifting mechanism and used for supporting materials or carriers of the materials and allowing the materials or the carriers to freely move in the horizontal plane. At least two sub guide structures extending in the vertical direction are arranged on the upper surface of the material, and a mother guide structure matched with the guide structures and extending in the vertical direction is arranged on the rack; the child guiding structure and the mothe
