the temporary storage assembly is configured to pick up a battery pack from the feeding module and push the battery piece picked up from the feeding module into the accommodating bin of the bin module; the temporary storage assembly is further configured to pick up a battery pack from a containing bin of the bin module and push the picked battery pack to the feeding module.

7. The battery pack stepper of claim 6, wherein the staging assembly comprises a mounting frame, a staging frame, a mounting plate, a displacement module, a rotation mechanism, wherein:

the temporary storage frame is used for accommodating at least one battery pack;

the temporary storage frame is rotatably mounted on the mounting frame through the rotating mechanism;

the displacement module drives the mounting frame to move along a second transverse direction, which is opposite to the first transverse direction;

the rotating mechanism drives the temporary storage frame to rotate, so that the material inlet and outlet of the temporary storage frame is in butt joint with the material inlet and outlet of the feeding module or the material inlet and outlet of the stock bin module.

8. The battery pack grading machine according to claim 7, wherein the temporary storage frame is provided with at least one storage bin, and the storage bin comprises a support plate, a push plate and a push plate driving member which are oppositely arranged;

the carrier plate is configured to carry a battery pack;

the push plate pulls the battery pack into the storage bin or pushes the battery pack out of the storage bin under the driving of the push plate driving piece.

9. The battery pack grading machine according to claim 8, wherein the pushing plate comprises a front pushing plate and a rear pushing plate, the front pushing plate is installed at a side close to the storage bin inlet/outlet, and the rear pushing plate is installed at a side far away from the storage bin inlet/outlet;

the height of the front push plate is smaller than that of the rear push plate;

the containing bin is internally provided with a bearing plate, and the side surface of the containing bin far away from the inlet and the outlet is provided with a barrier strip.

10. A battery pack grading method, wherein the battery pack grading machine according to claim 1 is used, and the battery pack grading method comprises:

when the battery pack at the first gear needs to be fed, the cache module is moved to the feeding module, and the cache module is controlled to pick up the battery pack which is loaded by the feeding module and has the first gear; the cache module is controlled to move to a position of a containing bin of a gear bin corresponding to a first gear, and the battery pack is pushed to the containing bin;

when the battery pack at the second gear needs to be discharged, controlling the cache module to move to a containing bin, corresponding to the gear bin at the second gear, where the battery pack is stored, and picking up and taking out the battery pack in the containing bin; and controlling the cache module to move to the feeding module, and pushing the picked battery pack to the feeding module.

11. The battery pack grading method according to claim 10, wherein with the battery pack grading machine according to claim 6, after the moving the buffer module to the feeding module, the battery pack grading method further comprises:

controlling a temporary storage frame of the temporary storage assembly to rotate 180 degrees so as to enable an inlet and an outlet of the temporary storage frame to be opposite to the feeding module;

after the cache module is controlled to move to the accommodating bin, corresponding to the gear bin of the second gear, where the battery pack is stored, the battery pack grading method further includes:

and controlling the temporary storage frame of the temporary storage assembly to rotate 180 degrees so as to enable the inlet and the outlet of the temporary storage frame to be opposite to the inlet and the outlet of the accommodating bin.
