[0040] In one embodiment of the present invention, referring to Figure 1 and Figure 2A large flat soft-pack battery formation and capacity division device 1 comprises a bracket 100, a battery clamp 200, a driving mechanism 300, a lifting mechanism 400 and a power connection mechanism 500. Support seats 101 are arranged on both sides of the upper end of the bracket 100, and rotating connecting shafts 201 are arranged on both sides of the battery clamp 200, which are rotatably connected with the corresponding support seats 101. Specifically, a bearing seat is arranged on the support seat 101, and the rotating connecting shaft 201 is connected to the bearing in the corresponding bearing seat. The battery clamp 200 is used for positioning and clamping during battery formation or capacity division. The bottom of the battery clamp 200 is provided with a clearance position 202 for avoiding empty battery pole ears. The driving mechanism 300 is arranged on one of the support seats 101, and is used to drive the battery clamp 200 to flip. The power connection mechanism 500 is arranged in the bracket 100 and is located at the bottom end of the battery clamp 200. The lifting end of the lifting mechanism 400 is connected to the power connection mechanism 500, which is used to lift the power connection structure 500 to connect with the positive and negative ears of the battery clamped in the battery clamp 200 to energize the battery. In this embodiment, when the battery is clamped into the battery clamp 200, the driving mechanism 300 drives the battery clamp to be in a vertical state, and the battery is placed horizontally in the battery clamp 200 and clamped, thereby ensuring that the battery is flat and the internal structure of the battery is evenly distributed. After the battery is clamped, the driving mechanism 300 drives the battery clamp 200 to flip 90° to a horizontal state, thereby avoiding the uneven internal structure of the battery due to gravity and ensuring the quality of battery formation or capacity distribution. When the battery is clamped in the battery clamp 200, when the power is connected, the lifting mechanism 400 pushes the power connection mechanism 500 to rise and clamp the positive and negative ears of the battery, so as to energize the battery. Since the ears of the battery extend out of the battery clamp, the heat dissipation performance is increased, and the heat of the ears is prevented from being transferred to the inside of the battery. And since the battery clamp and the power connection mechanism are independent of each other, the cross-section of the conductive part of the power connection mechanism can be increased, thereby increasing the current, thereby realizing large current formation and capacity division.

[0041] More specifically, in this embodiment, a battery is disposed between adjacent layers in the battery clamp 200 , and when the battery is clamped, the layers are pushed by power to compress the battery.

[0042] Furthermore, in an embodiment of the driving mechanism 300 , the driving mechanism 300 is an electric mechanism, including a driving motor disposed on the support seat 101 and a transmission mechanism for connecting the driving motor and the rotating connecting shaft 201 .

[0043] Furthermore, in another embodiment of the driving mechanism 300, the driving mechanism 300 includes a gear disposed on the rotating connecting shaft 201, a cylinder disposed on the supporting seat 201, and a rack connected to the cylinder piston rod, wherein the rack is meshed with the gear.

[0044] Furthermore, a limiting support frame 110 is also provided on the bracket 100. When the driving mechanism 300 drives the battery clamp 200 to rotate to a horizontal state, the bottom of the battery clamp 200 is supported on the bracket 100. When the driving mechanism 300 drives the battery clamp 200 to rotate to a vertical state, the limiting support frame 110 limits the battery clamp 200.

[0045] Furthermore, the large flat soft pack battery formation and capacity division device also includes a plurality of battery positioning clamps 600, please refer to Figure 1 and Figure 2 , used to position and clamp the battery. The battery positioning clamp 600 clamped with the battery is arranged between adjacent layers of the battery clamp 200. In this embodiment, for large flat batteries, due to their large volume, they are easy to deform and will cause the problem of uneven internal structure distribution. Therefore, when forming or dividing the large flat battery, the battery is positioned and clamped by the battery positioning clamp 600 to ensure that the battery is flat and the internal structure is evenly distributed. Ensure that the battery can be formed and divided normally, and ensure the quality of the battery.

[0046] Further, refer to Figure 3 and Figure 4 The battery positioning clamp 600 includes a first clamp 610, a second clamp 620, and a locking mechanism 630, wherein the locking mechanism 630 is used to lock the first clamp 610 and the second clamp 620; the first clamp 610 and the second clamp 620 are clamped together to form a accommodating cavity for accommodating battery cells, and a free position for avoiding the battery exhaust port is provided at the upper end of the accommodating cavity, and pressing members 640 are provided on both sides and the lower end of the clamping surface of the first clamp 610, which are used to press the battery edge seal on the inner side of the second clamp 620. In this embodiment, the battery cell portion of the large planar battery is placed in a accommodating cavity formed by the first clamping plate 610 and the second clamping plate 620, and the unsealed end of the battery passes through the avoidance position. The locking mechanism 630 locks the first clamping plate 610 and the second clamping plate 620, so that the clamping member 640 presses the sealed edge of the battery on the inner side of the second clamping plate 620, thereby tightening the battery, thereby fixing and positioning the battery and preventing it from deforming. Therefore, during battery processing and production, deformation can be prevented, and normal production and transportation during the production process can be ensured.

[0047] Further, refer to Figure 5 and Figure 6, there are multiple pressing members 640 arranged on both sides and the lower end of the clamping surface of the first clamping plate 610; the pressing members 640 include a pressing block 641 and a compression spring 642. The first clamping plate 610 is provided with a step hole for installing the pressing block 641, and the two sides of the pressing block 641 are provided with limiting parts 643, one end of the pressing block 641 passes through the step hole, and the two limiting parts 643 are limited on the step surface of the step hole; the compression spring 642 is arranged in the step hole, one end of the compression spring 642 abuts against the top wall of the step hole, and the other end abuts against the end of the pressing block 641. In this embodiment, when the first clamping plate 610 and the second clamping plate 620 press the battery, when the pressing block 641 contacts the second clamping plate 620, the compression spring 642 is compressed to press the edge of the battery, and at the same time, the first clamping plate 610 and the second clamping plate 620 move toward each other to further fix the battery cell.

[0048] Further, refer to Figure 4 , Figure 5 and Figure 6 The first clamping plate 610 includes a frame 611, a cover plate 612 and a silicone plate 613.

In this embodiment, when positioning the battery, the cover plate 612 and the silicone plate 613 are pressed together with the second clamping plate 620 to protect the battery, and the frame 611 is used to position the battery. In addition, the cover plate 612 can also limit the end of the compression spring 642.

[0049] Furthermore, the locking mechanism 630 is provided in multiple groups and is disposed on the first clamping plate 610. Figure 7 , Figure 8 and Fig. 9The locking mechanism 630 includes a connecting sleeve 631, a locking spring 632, a movable pin 633, a limiting pin 634 and a pressing sleeve 635. A mounting hole 614 is provided on the inner side of the first clamping plate 610, and a through hole for avoiding air is provided at the bottom of the mounting hole 614. The connecting sleeve 631 is installed in the mounting hole 614, and a blind hole is provided in the connecting sleeve 631. A guide hole is provided at the bottom of the blind hole, and the movable pin 633 passes through the guide hole in a sliding manner.

A limiting ring 636 for limiting the pressing sleeve 635 is provided at the end of the movable pin 633. A card slot is provided at the end of the movable pin 633 to facilitate connection with a tool for rotating the movable pin 633. The limit pin 634 passes through the movable pin 633 and extends out of one end of the blind hole. The locking spring 632 pushes the limit pin 634 to be limited at the end of the connecting sleeve 631. The second clamping plate 620 is provided with a connecting hole 621 corresponding to the locking mechanism 630, and both sides of the connecting hole 621 are provided with a clearance groove 622 for avoiding the limit pin 634. The pressing sleeve 635 is pushed to compress the locking spring 632, so that the movable pin 633 can slide along the guide hole, and the limit pin 634 passes through the second clamping plate 620 through the two clearance grooves 622. The movable pin 633 is rotated so that the limit pin 634 is misaligned with the clearance groove 622 and is limited on the outside of the first clamping plate 610. In this embodiment, when the first clamping plate 610 and the second clamping plate 620 are locked, they are locked by the locking mechanism 630; specifically, by pushing the pressing sleeve 635, the locking spring 632 is engaged, so that the locking spring 632 releases the movable pin 633, so that the movable pin 633 can rotate freely; therefore, when the movable pin 633 is rotated, the limiting pin 634 is misaligned with the avoidance groove 622, and the limiting ring 636 of the movable pin 633 and the locking spring 632 will not cause friction, which can not only avoid wear of both, but also smoothly rotate the movable pin 633. In addition, in this embodiment, the locking spring 632 is used to provide the locking force, so that the clamping force is too large to crush the battery, thereby protecting the battery.

In this embodiment, when the limiting pin 634 is limited on the outer side of the second clamping plate 620, the limiting pin 634 is positioned in the positioning groove 623 to prevent the movable pin 633 from rotating.

[0051] Furthermore, a pressing ring 637 is extended outwardly from the periphery of the pressing sleeve 635, and the limiting ring 636 is located inside the pressing ring 637. In this embodiment, the pressing sleeve 635 can be pushed by squeezing the pressing ring 637, so that the pressing sleeve 635 is easily squeezed.

[0052] Further, refer to Figure 3 and Fig.10 The two sides of the bottom of the battery positioning clamp 600 are also provided with supporting feet 601 supported on the bottom of the battery clamp 200. In this embodiment, the two supporting feet 601 of the battery positioning clamp 600 are supported on the bottom of the battery clamp 200, so that the battery positioning clamp 600 holding the battery can be supported in the battery clamp 200 and located between the layers.

[0054] Furthermore, a recessed cavity 624 is provided on the inner side of the second clamping plate 620, and a fixing frame 625 is provided in the cavity 624 for positioning the battery cell.
