In this way, the welding quality of the tab 210 is improved, the qualified rate of the cell 200 product is improved, the number of scrapped cell 200 with dislocated tab 210 is reduced, and the production efficiency is improved.

In this way, the battery cell 200 can be better positioned during the correction process, so as to improve the correction accuracy and improve the quality of the battery cell 200.

[0053] The working principle of the battery cell correction device 100 provided in the embodiment of the utility model is as follows:

[0054] The battery cell 200 is placed between the first correction plate 101 and the second correction plate 102. The first mounting base plate 113 and the first correction plate 101 are moved by the first driving member 111 and the first transmission member 112, the distance between the first correction plate 101 and the second correction plate 102 is adjusted, and the first correction plate 101 and the second correction plate 102 are pressed against the battery cell 200 in the first direction. Then, the first correction plate 101 and the second correction plate 102 are moved in the second direction by the second driving member 121 and the third driving member 131 respectively, and the friction between the first correction plate 101 and the battery cell 200 and the friction between the second correction plate 102 and the battery cell 200 are used to correct the position of the tab 210.

[0055] Specifically, the correction method is as follows:

[0056] Suppose that the tab 210 is misaligned to the left by 10 mm, the first correction plate 101 is moved downward under the driving of the first driving member 111, and stops when the first correction plate 101 is lowered to a set distance. At this time, the first correction plate 101 contacts the battery cell 200 on the second correction plate 102 and exerts a certain pressure on the battery cell 200. The first correction plate 101 is moved to the left in the second direction by the second driving member 121, so that the upper part of the battery cell 200 is moved to the left by 5 mm according to a set size. The second correction plate 102 is moved to the right in the second direction by the third driving member 131, so that the lower part of the battery cell 200 is moved to the right by 5 mm according to a set size. After the correction range is corrected, the first driving member 111 is started to continue driving the first correction plate 101 to lower to a set size, and then remains for a period of time, so that the battery cell 200 is fixed after correction. Then, the first driving member 111 drives the first correction plate 101 to rise and separate from the battery cell 200. The second driving member 121 and the third driving member 131 drive the first correction plate 101 and the second correction plate 102 to reset respectively, and the correction of one battery cell 200 is completed.

[0057] Suppose that the tab 210 is misaligned to the right. The battery cell 200 is placed on the second correction plate 102, the first correction plate 101 is lowered to contact the battery cell 200 and exerts a certain pressure on the battery cell 200. Then, the first correction plate 101 is moved to the right, and at the same time, the second correction plate 102 is moved to the left. The moving distance of the first correction plate 101 to the right is equal to the moving distance of the second correction plate 102 to the left. In this way, the position of the tab 210 can be adjusted to prevent the tab 210 from being misaligned.

[0058] It should be understood that, with the center line 201 in the Figure 8 The upper part of the battery cell 200 is above the center line 201, and the lower part of the battery cell 200 is below the center line 201.

[0059] In summary, the battery cell correction device 100 provided by the embodiment of the utility model has the following beneficial effects, including:

[0060] The first moving assembly 110 drives the first correction plate 101 to move up and down to adjust the gap between the first correction plate 101 and the second correction plate 102, keep clamping the battery cell 200, and fix the position of the battery cell 200 during the correction process. According to the misalignment of the tab 210, the second moving assembly 120 and the third moving assembly 130 are used to drive the first correction plate 101 and the second correction plate 102 to move reversely, respectively. The friction between the first correction plate 101, the second correction plate 102 and the battery cell 200 can be used to make the upper part and the lower part of the battery cell 200 move to the opposite direction, respectively, to correct the position of the tab 210, thereby improving the alignment accuracy of the tab 210. In this way, it is beneficial to improve the welding quality of the tab 210, improve the qualified rate of the battery cell 200 product, improve the product quality of the battery cell 200, reduce the scrap quantity of the misaligned battery cell 200, and improve the production efficiency.
