[0076] Then, the first driving member 321 drives the first limiting member 322 to extend along the Y axis, so that the first limiting member 322 extends along the Y axis from the front side of the frame 11 of the mobile vehicle 1 to block the push-in end of the mobile vehicle 1; after the mobile vehicle 1 is pushed into the two guide plates 35, the second driving member 323 drives the second limiting member 324 to rotate around the Z axis to abut against the push-in end of the frame 11 of the mobile vehicle 1, so as to limit the entire mobile vehicle 1 between the first limiting member 322 and the second limiting member 324; at this time, the bearing plate 2 is placed on each jack 3324.

[0077] Then, the third driving member 331 drives the wedge-shaped block 3321 to slide along the X axis, so that the roller 3325 rolls along the wedge-shaped top surface of the wedge-shaped block 3321, so as to drive the jack 3324 to slide upward along the Z axis, thereby driving the bearing plate 2 upward along the Z axis through the jack 3324, until the bearing plate 2 is completely separated from the top end of the frame 11, at this time, the bearing plate 2 is supported by each jack 3324.

[0078] Then, the positioning driving member 341 drives the positioning member 342 to insert into the positioning hole 221 of the positioning plate 22 along the Z axis, so as to position the bearing plate 2, thereby realizing accurate positioning of the battery pack 10 on the bearing plate 2, that is, at this time, the position of the battery pack 10 matches the position of the processing equipment of the processing position, so as to ensure the processing and assembling effect of the processing equipment on the battery pack 10, and improve the assembling qualified rate of the battery pack 10.

[0079] The battery pack positioning device in the embodiment can position the battery pack 10 through the bearing plate 2 and each limiting block 21 thereon for the first time, and then position the battery pack 10 through the first limiting member 322 and the second limiting member 324, each jack 3324 and the positioning member 342 for the second time, so as to ensure the accuracy and reliability of the positioning position of the battery pack 10 at the processing position.

[0080] The above is only a preferred embodiment of the present application, and for those skilled in the art, according to the idea of the present application, the specific implementation and application range can be changed, and the content of the specification should not be understood as a limitation of the present application.
