[0067] As shown in Figures 1-8 The present embodiment provides a battery cell module feeding and discharging system for feeding single-row battery cell modules 100 and discharging double-row battery cell modules 200. The single-row battery cell module 100 in the present embodiment refers to a battery cell module in which a plurality of battery cells are arranged in one direction.

The battery cell module feeding and discharging system has a first direction X, a second direction Z, and a third direction Y that intersect and are perpendicular.

[0068] The battery cell module feeding and discharging system includes a gantry 1, a workbench 2, a feeding device 3, and a discharging device 4.

The discharging device 4 is arranged on the sliding rail 11 and can slide along the sliding rail 11. The discharging device 4 is used to clamp the double-row battery cell module 200 located on the pre-pressing station 20 and transport the double-row battery cell module 200 to the discharging station 30.

[0069] The battery cell module feeding and discharging system provided in the present embodiment cooperates with the gantry 1 to feed the single-row battery cell module 100 from the feeding station 10 to the pre-pressing station 20, pre-presses two single-row battery cell modules 100 into a double-row battery cell module 200 at the pre-pressing station 20, and cooperates with the gantry 1 to discharge the double-row battery cell module 200 from the pre-pressing station 20 to the discharging station 30.

The first gripper group 32 is used to clamp a single row of battery cell modules 100. When loading a single-row battery cell module 100, the first drive mechanism 31 drives the first gripper group 32 to approach and move away from the loading station 10 along the height direction of the gantry 1 to grip the single-row battery cell module 100 on the loading station 10, and drives the first gripper group 32 to move the single-row battery cell module 100 from above the loading station 10 to above the pre-pressing station 20. Then, the first gripper group 32 is driven to place the single-row battery cell module 100 on the pre-pressing station 20. After the first gripper group 32 releases the single-row battery cell module 100, the first drive mechanism 31 drives the single-row battery cell module 100 to reset to above the loading station 10.

The second gripper group 42 then places the dual-row battery module 200 on the unloading station 30. After the second gripper group 42 releases the dual-row battery module 200, the second drive mechanism 41 drives the dual-row battery module 200 to reset to above the pre-pressing station 20.
