In an embodiment, referring to fig. 1-3, the stacking and compacting device includes a connecting seat 13 and a clamping mechanism, the connecting seat 13 is movably arranged on the mounting seat 10 along a first direction, two first sliding rails 101 parallel to each other are fixed on the upper surface of the mounting seat 10, the first sliding rails 101 extend along the first direction, and two opposite sides of the bottom of the connecting seat 13 are respectively connected with the two first sliding rails 101 in a sliding manner through sliding blocks; the clamping mechanism is arranged on the connecting seat 13 and is used for clamping the opposite side surfaces of the battery cells 30 to be stacked. It can be seen that the clamping mechanism is actuated in a first direction by the connecting seat 13.
In an embodiment, in order to enable the connection seat 13 to automatically move along the first direction, the stacking and compacting device further includes a driving unit, which is disposed on the mounting seat 10, and is used for driving the connection seat 13 to drive the clamping mechanism to move along the first direction; when the clamping mechanism moves to the set position under the driving of the connecting seat 13, the clamping mechanism is also used for placing the self-clamped battery cell 30 on the bearing plate 102. Specifically, the clamping mechanism includes a clamping cylinder 11 and two clamping jaws 110, the clamping cylinder 11 is disposed on the connecting seat 13, each clamping jaw 110 extends along the first direction, the clamping cylinder 11 is in driving connection with the two clamping jaws 110, and the clamping cylinder 11 is used for driving the two clamping jaws 110 to open and close. It can be understood that the two clamping jaws 110 can move along the first direction along with the connecting seat 13, and when two opposite sides of the battery cells 30 to be stacked need to be clamped, the clamping cylinders 11 drive the two clamping jaws 110 to close and clamp the battery cells 30 to be stacked; when the battery cell 30 needs to be placed on the carrier plate 102, the battery cell 30 can be placed on the carrier plate 102 by driving the two clamping jaws 110 to open through the clamping cylinder 11.
In an embodiment, referring to fig. 1-3, the clamping mechanism is slidably arranged on the connection seat 13 along the first direction, i.e. the clamping cylinder 11 of the clamping mechanism is capable of sliding along the first direction at the connection seat 13. In addition, a pushing mechanism is further disposed on the connection base 13, and the pushing mechanism is used for driving the clamping mechanism to move along the first direction and pushing the stacked battery cells 30 disposed on the carrier plate 102 along the first direction. Specifically, the pushing mechanism includes a pushing cylinder 14, a connecting plate 141 and a pushing plate 140, the pushing cylinder 14 is fixed on the connecting seat 13, the telescopic end of the pushing cylinder 14 extends along the first direction, the telescopic end of the pushing cylinder 14 is in driving connection with the connecting plate 141, the connecting plate 141 is in sliding connection with the second sliding rail 131 arranged on the connecting seat 13, the pushing plate 140 is fixed on the end surface of the connecting plate 141 facing away from the pushing cylinder 14, the clamping cylinder 11 is fixed on the bottom surface of the connecting plate 141, and the pushing plate 140 is located between the two clamping jaws 110. For example, when the two clamping jaws 110 clamp the first battery cell 30 and the two clamping jaws 110 are driven by the driving unit to move to the set position along the first direction, the clamping cylinder 11 releases the two clamping jaws 110 to place the first battery cell 30 on the carrier plate 102, and the pushing cylinder 14 pushes the pushing plate 140 to move along the first direction, so that the first battery cell 30 moves to abut against the limiting block 1021 along the first direction; when the two clamping jaws 110 of the clamping mechanism clamp the second battery cell 30 and the two clamping jaws 110 are driven by the driving unit to move to the set position along the first direction, the clamping cylinder 11 releases the two clamping jaws 110 to place the second battery cell 30 on the carrier plate 102, at this time, the pushing cylinder 14 pushes the pushing plate 140 to move along the first direction to move the second battery cell 30 to abut against the surface of the first battery cell 30 facing away from the limiting block 1021, and because the two clamping jaws 110 also move along with the pushing plate 140 along the first direction, in the process that the pushing plate pushes the second battery cell 30 to abut against the surface of the first battery cell 30 facing away from the limiting block 1021 along the first direction, the two clamping jaws 110 play a role of adjusting the side surfaces of the first battery cell 30 and the second battery cell 30.
It should be noted that, in the process of stacking the battery cells 30, since the surface of the carrying plate 102 carrying the battery cells 30 is a plane, and the two clamping jaws 110 play a role in adjusting the side surface parallel and level of the adjacent battery cells 30, the top surface of the battery cells 30 is pressed by the pressing mechanism without deviation, so that the four sides parallel and level of the stacked battery cells 30 can be ensured, the irregular external dimension of the battery pack formed by the stacked battery cells 30 is avoided, and the yield of the battery is improved.

Of course, the second flexible buffer member 1510 is disposed on the pressing surface of the first pressing member 151, so that the first pressing member 151 can be prevented from pressing the battery cell 30, and the battery cell 30 is protected.
