The invention discloses a side lifting and bottom supporting type carrying manipulator for a transferring box and a carrying method. The manipulator comprises a base, an inserting and bottom supporting mechanism, a side lifting mechanism and a pressing and edge hooking mechanism, wherein the inserting and bottom supporting mechanism, the side lifting mechanism and the pressing and edge hooking mechanism are correspondingly arranged on the base. The carrying method comprises the following steps: lifting one side of the transferring box through the side lifting mechanism so as to form an inclined gap in the bottom part of the transferring box; inserting the inserting and bottom supporting mechanism into the inclination gap and supporting to bottom part of the transferring box; hooking one side, relative to the side lifting mechanism, on the transferring box, through the pressing and edge hooking mechanism, and synchronously compressing the top surface of the transferring box, so as to fix the upper surface, the lower surface, the left surface and the right surface of the transferring box; then driving robot wrists to move to carry the transferring box. The carrying manipulator and the carrying method are specifically designed according to the properties of the general transferring box; each transferring box can be grasped from a surface layer of a stack and then carried to a specified place. Therefore, a plastic transferring box can be automatically removed from the stack, and an existing manual carrying manner is replaced, and as a result, the production efficiency can be effectively improved.
