The present embodiment differs from the previous embodiment in that the compression end in the present embodiment includes two compacts 74 so that the compression end is adjustable in the first direction. Thus, the pressing block 63 in the previous embodiment is suitable for a sub-cell having a smaller thickness, whereas the pressing block 74 in the present embodiment is adjustable and suitable for a sub-cell having a larger thickness.

In addition, because two pressing blocks 74 are provided, an extension driving member 73 is additionally provided in the present embodiment, and the extension driving member 73 is a gripper cylinder.

It should be explained that, when the first rotating plate 14 and the second rotating plate 15 are located at the first core combining position and the second core combining position, the two sub-battery cells are perpendicular to the first direction, and a certain distance is left between the two sub-battery cells, and the tab is located below the sub-battery cell, the thicker the thickness of the sub-battery cell is, the larger the distance between the tabs is, so that the adjustable pressing end is provided, and the pressing of the tab of the thicker sub-battery cell is realized.

In addition, in the process that the rotating plate rotates from the loading position to the core closing position, the pressing end does not always abut against the lug, in actual use, the rotating plate can rotate from the loading position to the core closing position after being turned for 90 degrees, and the pressing end is withdrawn when the rotating plate is turned for 60 degrees.

In order to facilitate understanding of the technical solution in the above embodiment, the workflow of the core combining device in the above embodiment is roughly described here:

initially, the first rotating plate 14 and the second rotating plate 15 are located at a first feeding position and a second feeding position respectively, the mechanical arm places the sub-cells at the first fixing position and the second fixing position, then the sub-cells are located in the second direction by the first locating assembly 31 and the second locating assembly 32, and the top cover is located by the second locating mechanism.

After positioning, the sub-battery cell is fixed through the fixing assembly 40, then the compression end rises to a certain height, the translational driving piece drives the compression end to move to the upper part of the electrode lug, and then the compression end descends to abut against the electrode lug (for a thicker sub-battery cell, the compression end can be unfolded by the stretching driving piece to form two pressing blocks and then descends).

After the compressing end is abutted to the lug, the rotating plate rotates, and when the rotating plate rotates to 60 degrees, the compressing end is withdrawn (when the compressing end comprises two pressing blocks, the two pressing blocks are lifted firstly, then the two pressing blocks are close to each other, and finally the pressing blocks are withdrawn along the second direction).

After the compressing end is withdrawn, the first rotating plate 14 and the second rotating plate 15 continue to rotate to the first core combining position and the second core combining position, respectively, and then the first driving assembly 21 and the second driving assembly 22 drive the first moving and supporting plate 12 and the second moving and supporting plate 13 to approach each other, so that the two sub-electric cores are attached to each other and compress the two sub-electric cores.

The utility model discloses still relate to a close core method, including following step:

s110, respectively placing the sub-cells in the first fixing position of the first rotating plate 14 and the second fixing position of the second rotating plate 15.

S120, the first rotating plate 14 is rotated to a first core-combining position around the first rotating axis, and the second rotating plate 15 is rotated to a second core-combining position around a second rotating axis parallel to the first rotating axis.

S130, the first transfer plate 12 and the second transfer plate 13 are close to each other, so that the sub-battery cells at the first fixing position and the sub-battery cells at the second fixing position are attached to each other and compressed.

When the first rotating plate 14 is located at the first core-closing position and the second rotating plate 15 is located at the second core-closing position, the first rotating plate 14 and the second rotating plate 15 are parallel to each other, a side of the first rotating plate 14 having the first fixing position and a side of the second rotating plate 15 having the second fixing position are disposed opposite to each other, and the first fixing position and the second fixing position are opposite to each other in the first direction.

By adopting the core combining method, after the sub-cells are placed on the first fixing position and the second fixing position, the first rotating plate 14 and the second rotating plate 15 are rotated to the first core combining position and the second core combining position, and then the first moving support plate 12 and the second moving support plate 13 are mutually close to each other, so that the sub-cells on the first fixing position and the sub-cells on the second fixing position are attached and compressed, a gap between the two sub-cells is avoided, and the core combining effect is improved.

In some embodiments, step S110 further comprises: the cap is positioned by the cap mount 51.

Further, step S120 further includes: and the top cover holder 51 is driven by the top driving member 52 to move in a third direction perpendicular to the first direction.
