a bearing member arranged on the base through the rotating member;

a first driving mechanism configured to apply a force to the bearing member from a first side of the bearing member; and

a second driving mechanism configured to apply a force to the bearing member from a second side, adjacent to the first side, of the bearing member;

wherein when the bearing member is subjected to force, a force is applied to the rotating member, the rotating member rotates in situ to drive the bearing member to move, and the bearing member is configured to, when moving to a first preset position, bear an energy storage cabinet in the production process of an energy storage production line of batteries.

2 . The positioning apparatus according to claim 1 , wherein:

two first driving mechanisms are provided and are respectively arranged on the first side and a third side, opposite to the first side, of the bearing member; and

the first driving mechanisms are configured to apply forces to the bearing member from the first side and the third side respectively.

3 . The positioning apparatus according to claim 2 , wherein:

each of the first driving mechanisms comprises a first driving member, a lead screw, and a first pushing member;

the first driving member and the first pushing member are connected to two ends of the lead screw respectively, the first driving member is fixed to the base, and the first pushing member is located between the bearing member and the first driving member;

the lead screw is driven by the first driving member to rotate so as to drive the first pushing member to move in the axis direction of the lead screw; and

the first pushing member pushes the bearing member when moving.

4 . The positioning apparatus according to claim 3 , further comprising:

a clamping mechanism, wherein the clamping mechanism comprises:

two supports which are arranged on the first side and the third side respectively, the supports being fixed to the lead screws; and

two clamping plates which are fixed to the supports respectively, arranged in the direction facing the bearing member, and configured to clamp the energy storage cabinet borne by the bearing member;

wherein the lead screws rotate to drive the supports to move in the axis direction of the lead screws, to increase or decrease the distance between the two supports, and therefore the two clamping plates clamp the energy storage cabinet.

5 . The positioning apparatus according to claim 4 , wherein the clamping mechanism further comprises:

at least two third driving mechanisms fixed to the supports;

at least two second pushing members which are respectively connected to the third driving mechanisms and arranged in the direction facing the bearing member, the two third driving mechanisms being configured to drive the two second pushing members respectively to reciprocate in the direction of the second side, so that the two second pushing members clamp the energy storage cabinet from two opposite sides of the energy storage cabinet; and

at least two fourth driving mechanisms which are fixed to the supports and respectively connected to the second pushing members, the two fourth driving mechanisms being configured to drive the two second pushing members respectively to reciprocate in the direction of the first side, the second pushing members applying a force to the energy storage cabinet when moving, and the energy storage cabinet applying a friction force to the bearing member so as to push the energy storage cabinet to a second preset position.

6 . The positioning apparatus according to claim 1 , wherein:

the second driving mechanism comprises a third pushing member and a second driving member;

the third pushing member is connected to the second driving member;

the second driving member is fixed to the base;

the second driving member is configured to drive the third pushing member to move; and

the third pushing member applies a force to the bearing member when moving.

7 . The positioning apparatus according to claim 1 , wherein:

the bearing member is provided with a first position-limiting mechanism, and the base is provided with a second position-limiting mechanism; and

when the bearing member moves to a third preset position, the bearing member is limited on the base through the cooperation of the first position-limiting mechanism and the second position-limiting mechanism, and therefore relative displacement between the bearing member and the base is avoided.

8 . The positioning apparatus according to claim 7 , further comprising:

a fifth driving mechanism which is connected to the second position-limiting mechanism and configured to drive the second position-limiting mechanism to move to the first position-limiting mechanism to cooperate with the first position-limiting mechanism when the bearing member moves to the third preset position.

9 . The positioning apparatus according to claim 1 , further comprising:

a sensor which is fixed to the base and configured to detect the position of the bearing member;

wherein the sensor is connected with a peripheral device, to enable the peripheral device to place the energy storage cabinet on the bearing member according to the position, detected by the sensor, of the bearing member.

10 . The positioning apparatus according to claim 1 , wherein the rotating member comprises universal balls arranged on the base at intervals.

11 . A positioning system, comprising:

the positioning apparatus according to claim 1 ; and

a peripheral device configured to place the energy storage cabinet on the bearing member.
