[0046] Refer to the following Figures 1 to 8 A device for eliminating bubble spots inside a soft-pack battery according to some embodiments of the present application is described.

[0047] Embodiment 1

[0048] See also Figures 1 to 4 As shown, an embodiment of the present application provides a device for eliminating bubble spots inside a soft-pack battery, comprising: a conveying mechanism 3 and two rolling mechanisms, which are respectively named as a first rolling mechanism 1 and a second rolling mechanism 2 for the convenience of distinguishing the two rolling mechanisms; wherein the first rolling mechanism 1 and the second rolling mechanism 2 are sequentially arranged along a preset direction; the conveying mechanism 3 is formed with a first rolling area 38 and a second rolling area 39 sequentially arranged along the preset direction;

[0049] The first rolling zone 38 of the conveying mechanism 3 can reciprocate relative to the first rolling mechanism 1, and is used to reciprocate and roll the soft-pack batteries placed on the first rolling zone 38. The second rolling zone 39 of the conveying mechanism 3 can reciprocate relative to the second rolling mechanism 2, and is used to synchronously reciprocate and roll the soft-pack batteries placed on the second rolling zone 39.

[0050] Based on the structure described above, it can be seen that the working principle of the device for eliminating bubble spots inside a soft-pack battery provided in the present application is as follows:

[0051] In the initial state, the second rolling area 39 is located at the middle position 7 between the first rolling mechanism 1 and the second rolling mechanism 2. The robot moves the No. 2 soft-pack battery 10 from the waiting rolling area to the second rolling area 39, and then moves the No. 2 soft-pack battery 10 forward along the preset direction, that is, the first preset direction a, to the No. 2 rolling position 8, and cooperates with the second rolling mechanism 2 to roll the No. 2 soft-pack battery 10 once;

[0052] After the first rolling of the No. 2 soft-pack battery 10 is completed, the first rolling zone 38 is located at the middle position 7, and the robot puts the No. 1 soft-pack battery 9 newly added to the rolling area in the first rolling zone 38;

[0053] Then, the No. 1 soft-pack battery 9 and the No. 2 soft-pack battery 10 are moved in the direction opposite to the first preset direction a, that is, the second preset direction b, so that the No. 1 soft-pack battery 9 passes through the No. 1 rolling position 6, and the first rolling mechanism 1 performs a first rolling on the No. 1 soft-pack battery 9, and at the same time, the No. 2 soft-pack battery 10 passes through the No. 2 rolling position, and the second rolling mechanism 2 performs a second rolling on the No. 2 soft-pack battery 10;

[0054] After the first rolling of the No. 1 soft-pack battery 9 and the second rolling of the No. 2 soft-pack battery 10 are completed, the second rolling area 39 is relocated to the middle position 7, and then the No. 2 soft-pack battery 10 located at the middle position 7 is removed from the second rolling area 39 by a robot, and the No. 3 soft-pack battery 11 is moved from the waiting rolling area to the second rolling area 39, and then the above steps are repeated.

[0055] It can be seen that the device for eliminating bubble spots inside soft-pack batteries provided in the present application is based on the form of rolling, and a rolling process is added after the original double sealing process. That is to say, a rolling process is added for each soft-pack battery, so that the small amount of gas remaining in the battery pole piece after the double sealing is vacuumed is discharged from the pole piece surface, which can efficiently and stably eliminate the bubble spots on the battery pole piece. In addition, the two rolling positions are synchronously linked, which greatly improves the production efficiency and realizes continuous and uninterrupted production.

[0056] It should be noted that the middle position 7 refers to the workstation located between the first rolling mechanism 1 and the second rolling mechanism 2, the first rolling position refers to the rolling position when rolling in contact with the first pressing roller 104, and the second rolling position refers to the rolling position when rolling in contact with the second pressing roller 204.

[0111] After the first rolling of the No. 2 soft-pack battery 10 is completed, the first rolling zone 38 is located at the middle position 7, and the robot puts the No. 1 soft-pack battery 9 newly added to the rolling area in the first rolling zone 38;

[0112] Then, the No. 1 soft-pack battery 9 and the No. 2 soft-pack battery 10 are moved in the direction opposite to the first preset direction a, that is, in the second preset direction b (that is, backward), until the No. 1 soft-pack battery 9 enters the No. 1 rolling position 6. At this time, the first driving device 102 drives the first pressing roller 104 to descend to a preset height, so that the first pressing roller 104 is pressed on the rear end of the No. 1 soft-pack battery 9. At this time, the second pressing roller 204 is in contact with the rear end of the No. 2 soft-pack battery 10, and the conveying driving device 31 drives the No. 1 soft-pack battery 9 and the No. 2 soft-pack battery 10 to move backward at the same time along the second preset direction b, thereby realizing the first rolling of the No. 1 soft-pack battery 9 and the second rolling of the No. 2 soft-pack battery 10;

[0113] When the first rolling of the No. 1 soft-pack battery 9 and the second rolling of the No. 2 soft-pack battery 10 are completed at the same time, the second rolling area 39 is relocated to the middle position 7, and then the No. 2 soft-pack battery 10 located at the middle position 7 is removed from the second rolling area 39 by a robot, and the No. 3 soft-pack battery 11 is moved from the waiting rolling area to the second rolling area 39, and then the above steps are repeated.
