When the upper pressing plate 31 and the conveying belt line 32 are close to each other, the battery core wound into a roll can be flattened; the flattened coiled battery cell 4 is conveyed by the conveying belt line 32 for blanking, so that the production efficiency of the battery cell is further improved.
Specifically, the conveying belt line 32 includes a conveying belt 321, a driving wheel 322 and a driven wheel 323, two ends of the conveying belt 321 are sleeved on the driving wheel 322 and the driven wheel 323, the driving wheel 322 is in transmission connection with an output end of a motor 5, the driving wheel 322 drives the driven wheel 323 to rotate through the conveying belt 321, and the conveying belt 321 moves and drives the coiled battery cell 4 to discharge.
When the coiled battery cell 4 is discharged, the upper pressing plate 31 and the conveying belt line 32 are firstly close to each other to flatten the coiled battery cell 4 in a round coil, so that the phenomenon that the coiled battery cell 4 is easy to loosen in the carrying process is avoided; then, the upper press plate 31 and the conveyor belt line 32 are away from each other, the conveyor belt 321 of the conveyor belt line 32 is driven to work, and the flattened coiled battery cell 4 is conveyed and discharged to complete discharging.
In the preferred embodiment, and as further shown in FIGS. 1 a-1 c, the upper platen 31 is mounted on an elevator mechanism. The vertical lifting mechanism comprises a longitudinal linear rail 6, a ball screw 7 and a motor 5, wherein the longitudinal linear rail is arranged in the vertical direction along the length direction, one end, far away from the coiled battery cell 4, of the upper pressing plate 3 is connected with the ball screw 7 and is arranged on the longitudinal linear rail 6 in a sliding mode, the ball screw 7 is connected with the output end of the motor 5 through a coupler 8, and the upper pressing plate 31 can be driven to move up and down through the motor 5.
Similarly, the conveyor belt line 32 is also provided in an elevating mechanism which also includes a longitudinal wire rail 6 whose length direction runs in the up-down direction, a ball screw 7, a motor 5, and an elevating platform 324. The lifting platform 324 is connected with the wheel shaft of the driving wheel 322 and the driven wheel 323 through bearings, the conveying belt 321 is actually arranged outside the lifting platform 324, and when the upper pressing plate 31 and the conveying belt line 32 approach each other to flatten the coiled battery cell 4, the conveying belt line 32 actually presses the coiled battery cell 4 through the lifting platform 324, so that damage to the conveying belt 321 caused by overlarge pressure when the upper pressing plate 31 presses the coiled battery cell 4 is avoided, or the coiled battery cell 4 cannot be flattened due to deformation of the conveying belt 321. The bottom of the lifting platform 324 is connected with the ball screw 7 and is arranged on the longitudinal wire track 6 in a sliding mode, the ball screw 7 is connected with the output end of the motor 5 through the coupler 8, and the motor 5 can drive the conveying belt wire 32 to move up and down.
Therefore, the upper pressing plate 31 and the conveying belt line 32 can be controlled to be close to or away from each other, and accordingly the coil battery cell 4 can be effectively flattened. Further, the motor 5 in the up-down lifting mechanism connecting the upper platen 31 and the up-down lifting mechanism connecting the conveyor belt line 32 can be controlled in linkage by the controller.
