The centering and adjusting member 403 comprises a supporting slide frame 4034, an adjusting push plate 4032, two adjusting vertical plates 4031 and two centering side plates 4035, the adjusting push plate 4032, the two adjusting vertical plates 4031 and the two centering side plates 4035 are all rectangular in shape, and the adjusting push plate 4032, the two adjusting vertical plates 4031 and the two centering side plates 4035 are all fixedly provided with buffer plates on the side in contact with the battery cell 5.

[0028] The supporting slide frame 4034 is suspended on the bearing flat plate 402, the top of the supporting slide frame 4034 is located above the bearing flat plate 402, and the bottom of the supporting slide frame 4034 is located in the gap between the bearing flat plate 402 and the mounting platform 2. The two adjusting vertical plates 4031 are arranged at the bottom of the supporting slide frame 4034 and are respectively located at the two sides of the bearing flat plate 402, and the two adjusting vertical plates 4031 are opposite to the side of the fixed stacking vertical plate 401 to form a reference surface for positioning the front side of the battery cell 5. The adjusting cylinder 4037 is arranged below the supporting slide frame 4034, and the adjusting cylinder 4037 can drive the two adjusting vertical plates 4031 to move relatively close to the bearing flat plate 402 along the transverse direction of the bearing flat plate 402 to serve as the reference surface for adjusting the front side of the battery cell 5.

[0029] The adjusting push plate 4032 is arranged at the top of the supporting slide frame 4034, and the top of the supporting slide frame 4034 is provided with a push-moving driving member for driving the adjusting push plate 4032 to move towards the fixed stacking vertical plate 401, and the push-moving driving member is a push-moving cylinder 4033, the adjusting push plate 4032 is pushed to move the battery cell 5 along with the extension of the extension rod of the push-moving cylinder 4033, the battery cell 5 is first pushed against the reference surface of the adjusting vertical plate 4031 for adjustment, and after the adjustment and centering of the battery cell 5 are completed, the battery cell 5 is pushed towards the fixed stacking vertical plate 401 for stacking.

[0030] Further, two push-moving stabilizing slide columns are slidably arranged around the extension rod in the push-moving cylinder 4033, the end of the push-moving stabilizing slide column extending out of the push-moving cylinder 4033 is fixedly connected with the adjusting push plate 4032, and the arrangement of the push-moving stabilizing slide column can increase the stability of the extension rod of the push-moving cylinder 4033 when pushing the adjusting push plate 4032 to move.

[0031] Two centering side plates 4035 are arranged between the adjusting vertical plates 4031 and the support carriages 4034 to bear the flat plates 402 on both sides, and a centering cylinder 4036 is arranged between the support carriages 4034 and the adjusting cylinder 4037 to drive the two centering side plates 4035 to move synchronously and in the same amplitude. The two centering side plates 4035 can move relative to each other to clamp and center the battery cell 5 under the driving of the centering cylinder 4036. After the battery cell 5 is centered, the two centering side plates 4035 move in opposite directions under the driving of the centering cylinder 4036 to release the battery cell 5, so that the adjusting push plate 4032 can push the centered battery cell 5 to complete the stacking. The centering and adjusting member 403 in the device can quickly center and adjust the battery cell 5 before stacking, so as to avoid misalignment and misalignment during stacking.

[0032] The number of the joint driving assembly 7 is two, and one joint driving assembly 7 is arranged between each adjacent two flat plates 402. The joint driving assembly 7 can drive the two adjacent centering and adjusting members 403 to move synchronously along the flat plate 402 and can cooperate with the fixed stacking vertical plate 401 to stack the battery cell 5.

[0033] The joint driving assembly 7 comprises a lead screw 703, a nut installed on the lead screw 703, and a second driving motor 702 for driving the lead screw 703 to rotate. The lead screw 703 is arranged in parallel with the two flat plates 402, and the two ends of the lead screw 703 are arranged on the mounting platform 2 through bearing supports arranged for supporting and rotating. The output shaft of the second driving motor 702 is connected to one end of the lead screw 703 near the fixed stacking vertical plate 401 through a shaft coupling.

[0034] A few-shaped connecting plate 701 is fixed on the nut. The left and right ends of the connecting plate 701 are fixedly connected to the bottoms of the adjacent two support carriages 4034, so that when the nut moves with the rotation of the lead screw 703, the two support carriages 4034 can be driven by the connecting plate 701 to move synchronously along the corresponding flat plate 402 to adjust and center the stacked battery cell 5.

[0035] Further, in order to ensure that the two support carriages 4034 remain stable during movement, a second sliding rail 4038 and a bent wire tube 6 are arranged on the mounting platform 2 outside the adjacent two flat plates 402. One of the two adjacent support carriages 4034 is connected to the movable end of the corresponding side bent wire tube 6 through a support plate 601, and the other support carriage 4034 is provided with a second sliding block 4039 for sliding cooperation with the corresponding side second sliding rail 4038, so that the two adjacent support carriages 4034 can slide and push the stacked battery cell 5 stably.

[0036] Further, the joint drive assembly 7 is provided with a protective cover 4040 outside the periphery, and two rollers are rotatably arranged on the upper side of the connecting plate 701. When the nut moves along the screw rod 703, the connecting plate 701 can be rolled with the inner side of the protective cover 4040 through the two rollers.

[0037] As shown in Figure 1 Any one layer of the cell adjusting and stacking mechanism can be slid to the loading port on the right side of the mounting chassis 1 or the discharging port on the left side through the sliding drive assembly 3, so that two layers of the cell adjusting and stacking mechanism can alternately stack the cells 5 to form a battery module and move the stacked cell 5 module to the position of the discharging port for the next process, realizing the synchronous operation of the assembly and discharging of the battery module, and greatly improving the stacking efficiency of the cells 5.

[0038] The sliding drive assembly 3 includes a first drive motor 301 and two first sliding rails 303. One first sliding rail 303 is arranged on each of the mounting support vertical plates 101 on both sides of the mounting platform 2 of the upper cell adjusting and stacking mechanism. The direction in which the first sliding rail 303 is arranged on the upper cell adjusting and stacking mechanism is set, and a plurality of first sliding blocks 302 are arranged on each first sliding rail 303.

[0039] The first drive motor 301 is fixed on the mounting slide 201, and a driving gear is mounted on the output shaft end of the first drive motor 301. One rack 304 is mounted on the outer side of one of the two first sliding rails 303, and the rack 304 can be engaged with the corresponding driving gear. The rack 304 is distributed along the length of the first sliding rail 303. When the cells 5 on the upper cell adjusting and stacking mechanism are stacked, the upper cell adjusting and stacking mechanism at the loading port on the right side of the mounting chassis 1 can be moved to the position of the discharging port on the left side of the mounting chassis 1 under the drive of the first drive motor 301, so as to move the battery module to the next process.

[0040] Correspondingly, the structure of the sliding drive assembly 3 at the lower cell adjusting and stacking mechanism is the same as that of the sliding drive assembly 3 at the upper cell adjusting and stacking mechanism, and the only difference is that the two first sliding rails 303 on both sides of the lower cell adjusting and stacking mechanism are fixed on the mounting platform. When the battery module on the lower cell adjusting and stacking mechanism is discharged, the lower cell adjusting and stacking mechanism at the discharging port on the left side of the mounting chassis 1 can be moved towards the loading port on the right side of the mounting chassis 1 under the drive of the corresponding first drive motor 301 to stack the cells 5. Through the reciprocating movement of the upper and lower cell adjusting and stacking mechanisms, the stacking efficiency of the cells 5 is greatly improved.

[0041] The process of adjusting the center stacking of the battery cells 5 of the utility model is as follows: first, the four battery cells 5 grabbed by the battery cell 5 robot are placed as follows: Figure 1 As shown, on the four upper supporting plates 402, the battery cells 5 are positioned between corresponding two centering plates 4035. The alignment cylinder 4037 is activated, causing the two alignment vertical plates 4031 to slide relative to each other and approach the supporting plates 402. The push cylinder 4033 is then activated, causing the alignment push plate 4032 to move and push the front side of the battery cell 5 against the reference surfaces of the two centering plates 4035, completing the alignment. The two centering plates 4035 then move in opposite directions, and the alignment cylinder 4036 is activated again. The two centering plates 4035 slide relative to each other, clamping the centering battery cell 5 before opening.

[0042] The second drive motor 702 is then started, and the entire support slide 4034 moves toward the fixed stacking riser 401. The centered battery cells 5 are then stacked under the push of the alignment push plate 4032. When the battery cells 5 on the upper-level adjustment battery cell 5 stacking mechanism are stacked, the corresponding first drive motor 301 is started, and the upper-level adjustment battery cell 5 stacking mechanism moves from the feed port to the discharge port for discharge. At the same time, the lower-level adjustment battery cell 5 stacking mechanism, which has discharged the stacked battery cells 5, is driven by the corresponding first drive motor 301 to move to the feed port to stack the battery cells 5 again.
