[0002] The short knife battery cell is a new battery cell category launched for the future development of power batteries. It is obtained by stacking multiple long and thin batteries according to certain series-parallel rules based on the lamination process. It is shorter in length, has lower internal resistance, and generates less heat. The performance of the battery cell itself is better than that of the traditional module battery pack. In the manufacturing process of the short knife battery cell module, it is necessary to determine the positive and negative polarity direction of the battery cell. After adjusting the polarity direction of the battery cell based on the determination result, the positive and negative poles of several battery cells are arranged into groups according to certain series-parallel rules. The traditional adjustment scheme is to rotate the battery cell in the X direction and then in the Y direction. This action is more cumbersome and requires two rotations to complete the adjustment of the polarity direction of the battery cell. In addition, the two rotating devices take up a large space.

[0012] When the lifting mechanism drives the clamping mechanism to rise to the clamping position, the rotating mechanism drives the two battery cell clamps to rotate to reverse the polarity direction of the battery cell;

[0013] When the rotation of the battery core is completed and the lifting mechanism drives the clamping mechanism to descend to the rotation position again, the clamping mechanism drives the two side plates to open to release the battery core.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] It should be noted that in the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] Figure 1 A front view of a preferred embodiment of the present invention is given. Figure 2 A side view of a preferred embodiment for this purpose; Figure 1 , Figure 2 , Figure 6As shown, a battery cell rotation assembly device includes a clamping mechanism 1, a rotating mechanism 2, and two symmetrically arranged battery cell clamps 6. The battery cell clamps 6 include side plates 61 and battery cell blocks 62. The battery cell blocks 62 are rotatably arranged at the bottom of the side plates 61. The side plates 61 are transmission-connected to the clamping mechanism 1, and the rotating mechanism 2 is transmission-connected to the battery cell blocks 62. During operation, the clamping mechanism 1 drives the two side plates 61 to move toward each other, so that the battery cell clamps 6 are retracted to clamp the battery cell. Then, the rotating mechanism 2 drives the two battery cell blocks 62 to rotate to reverse the polarity of the battery cell. After the rotation of the battery cell is completed, the rotating mechanism 2 drives the two side plates 61 to move in opposite directions, so that the battery cell clamps 6 are opened to release the battery cell. Since only one rotation is required after clamping the battery cell, the original positive pole of the battery cell can be changed to the negative pole, thereby speeding up the production rhythm. The specific rotation direction of the battery cell is as follows: Fig. 9 As shown; specifically, the rotation angle of the battery cell can be set to 180 degrees so that the polarity direction of the battery cell can be completely reversed.

[0042] Further, such as Figure 4 , Figure 5 , Figure 8 As shown, the clamping mechanism 1 includes a clamping drive 11 and a mounting plate 12. The clamping drive 11 is horizontally arranged. The two ends of the clamping drive 11 are respectively connected to the mounting plate 12 and a side plate 61 in a battery cell clamp 6, and the side plate 61 in a battery cell clamp 6 is slidably mounted on the mounting plate 12. For example, the sliding mounting method includes installing two linear guides on the bottom surface of the mounting plate 12, and each linear guide is provided with two sliders. A connecting plate is connected to the top of the side plate 61, and the connecting plate is fixedly connected to the two sliders located on different linear guides; the slidable installation of the side plate 61 is realized by the linear guide, and the first side plate 12 and the second side plate 13 are driven to move toward or away from each other by the movable end of the clamping drive 11, so as to realize the clamping or loosening action of the battery cell. Specifically, the clamping drive 11 can use a clamping cylinder type drive. The side plates 61 in the two battery cell clamps 6 are respectively provided with a first rack 13 and a second rack 14, and a bearing 121 is rotatably mounted on the mounting plate 12. A gear 122 is sleeved on the outer side of the bearing 121, and the two sides of the gear 122 are respectively meshed with the first rack 13 and the second rack 14; the synchronous movement of the two side plates 61 is achieved through the meshing transmission of the rack 13, the second rack 14 and the gear 122.

[0043] Further, such as Figure 1 , Figure 2As shown, the battery cell rotation assembly device also includes a lifting mechanism 3 and a fixed bracket 4. The tightening mechanism 1 is arranged on the lifting mechanism 3, and the lifting mechanism 3 is arranged on the fixed bracket 4. The lifting mechanism 3 has a clamping position and a rotating position. The lifting mechanism 3 is used to drive the clamping mechanism 1 to perform a lifting action between the clamping position and the rotating position. When the lifting mechanism 3 drives the clamping mechanism 1 to descend to the clamping position for the first time, the clamping mechanism 1 drives the two side plates 61 to close to clamp the battery cell, and then the lifting mechanism 3 drives the clamping mechanism 1 to be lifted to the clamping position. After it is in place, the rotating mechanism 2 drives the battery cell to rotate to reverse the polarity direction of the battery cell; after the battery cell rotation action is completed, the lifting mechanism 3 drives the clamping mechanism 1 to descend to the rotating position again. After it is in place, the clamping mechanism 1 drives the two side plates 61 to open and release the battery cell; by setting the lifting mechanism 3 to drive the battery cell to lift a certain height and then using the rotating mechanism 2 to drive the battery cell to rotate, sufficient rotation space for the battery cell is guaranteed to avoid interference between the battery cell and other devices such as a feeding device when the battery cell is rotated.

[0044] Further, such as Figure 3 As shown, the fixed bracket 4 includes a top plate and two columns, and the two ends of the top plate are fixedly connected to the tops of the two columns respectively; the lifting mechanism 3 includes a lifting drive 31, which is vertically arranged on the top plate, and the action end of the lifting drive 31 is connected to the mounting plate 12 through a floating joint, and the floating joint is used to make the lifting drive 31 and the mounting plate 12 stably connected within the allowable eccentricity range, while maintaining the stable movement of the lifting drive 31; the fixed bracket 4 also includes a support plate and multiple guide columns, the support plate is located above the top plate, one end of the guide column is fixedly connected to the mounting plate 12, and the other end of the guide column passes through the top of the support plate; the guide column is used for guiding to improve the stability of the lifting mechanism 3 when performing lifting actions; the number of guide columns is generally set to more than 4, and this embodiment does not limit this. Specifically, the lifting drive 31 can use a lifting cylinder type drive.

[0045] Further, such as Figures 6 to 8As shown, the battery clamp 6 also includes a synchronization mechanism 5, a first rotating shaft 63 is inserted at the top of the side plate 61, a second rotating shaft 64 is inserted at the bottom of the side plate 61, the second rotating shaft 64 is connected to the battery clamp block 62, and the second rotating shaft 64 is also connected to the first rotating shaft 63 through the synchronization mechanism 5. The rotating mechanism 2 includes a rotating drive member 21 and a rotating main shaft 22. The rotating shaft of the rotating drive member 21 is connected to the first rotating shaft 63 in another battery clamp 6 through the first rotating shaft 63 and the rotating main shaft 22 in one battery clamp 6. The rotating drive member 21 rotates to drive the rotating main shaft 22 to rotate, and the rotating main shaft 22 rotates to drive the second rotating shaft 64 to rotate through the synchronization mechanism 5. The battery clamp block 62 rotates with the second rotating shaft 64, thereby realizing the reversal of the positive and negative poles of the battery; the battery clamps 6 on both sides use the rotating drive member 21 as the only power source, which is conducive to ensuring the synchronization of the rotation action. Specifically, the rotating drive member 21 can be a rotating cylinder type drive member.

[0046] Furthermore, the rotating main shaft 22 is a retractable universal coupling. The retractable universal coupling has both power transmission and retractable functions, that is, when the clamping mechanism 1 is clamping or releasing, it can still connect the first rotating shafts 63 on both sides, so that the first rotating shafts 63 on both sides keep rotating synchronously, thereby preventing the battery core from being deformed due to the asynchronous rotation of the two sides.

[0047] Further, such as Figure 6 , Figure 7 As shown, the synchronization mechanism 5 includes a first pulley 51, a second pulley 52, a synchronous belt 53, and a synchronous belt tensioner. The first pulley 51 is sleeved outside the first rotating shaft 63, and the second pulley 52 is sleeved outside the first rotating shaft 64. The first pulley 51 and the second pulley 52 are connected by the synchronous belt 53. The synchronous belt tensioner is arranged on the outside of the synchronous belt 53 to ensure the transmission stability of the first synchronization mechanism 6. The synchronization mechanism 5 ensures the synchronous rotation of both sides.

[0048] Further, such as Figure 4 , Figure 5 As shown, the battery cell rotation assembly device also includes a displacement sensor 7, which is installed on the clamping mechanism 1, specifically, on the mounting plate 12, and is used to detect the moving distance of the side plate 61. Since the side plates 61 on both sides move synchronously, it is only necessary to detect whether one of them moves to the right position. The maximum distance between the side plate 61 and the displacement sensor 7 is pre-set to prevent the battery cell from being deformed due to excessive clamping.

[0049] Further, such as Figure 7 As shown, the battery clamp 62 is provided with an elastic block 65, and the elastic block 65 is provided with a groove 651, and the groove 651 is used to match the side of the battery. The elastic block 65 is made of, for example, a rubber elastic material, and is used to protect the battery and prevent the battery from being scratched or deformed.

[0050] The present invention can complete the adjustment action of the polarity direction of the battery cell at one time, and there is no need to realize the battery cell adjustment and grouping function by rotating the battery cell multiple times, thereby simplifying the equipment structure, improving the action rhythm, improving the production efficiency, and reducing the space occupied by the equipment.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution, improvement, etc. made under the concept of the present invention should be included in the protection scope of the present invention.
