[0044] The conveying device 100 provided in the present application is mainly used for conveying battery cells or other sheet materials; it can also convey materials of other shapes.

[0045] like Figure 1 and Figure 2 As shown, the conveying device 100 includes a first conveying mechanism 1 , a second conveying mechanism 2 and a support assembly 3 .

[0046] The first conveying mechanism 1 and the second conveying mechanism 2 are spaced apart along the Y direction. The conveying direction of the first conveying mechanism 1 is the X direction, and the conveying direction of the second conveying mechanism 2 is the X direction.

[0047] To further illustrate, a first mounting portion 14 is provided on the first conveying mechanism 1, and a second mounting portion 24 is provided on the second conveying mechanism 2. The projections of the first mounting portion 14 and the second mounting portion 24 in the Y direction coincide with each other. That is, when the first conveying mechanism 1 causes the first mounting portion 14 to move along the X direction and the second conveying mechanism 2 causes the second mounting portion 24 to move along the X direction, the first mounting portion 14 and the second mounting portion 24 will move synchronously, and their projections in the Y direction will always remain in a coincidence state.

The second driving wheel 21 and the second driven wheel 22 are spaced apart in the X direction. The second conveyor belt 23 is sleeved on the second driving wheel 21 and the second driven wheel 22. The second conveyor belt 23 can rotate around the second driving wheel 21 and the second driven wheel 22, that is, the second conveyor belt 23 can move along the X direction, thereby realizing the movement of the second conveying mechanism 2 in the X direction. The conveying device 100 also includes a driving mechanism 4, the conveying shaft of the driving mechanism 4 is connected to the first driving wheel 11 and the second driving wheel 21, and the driving mechanism 4 can simultaneously drive the first driving wheel 11 and the second driving wheel 21 to rotate, so that the first conveyor belt 13 and the second conveyor belt 23 can rotate at the same time, thereby improving the movement synchronization rate of the first conveyor belt 13 and the second conveyor belt 23, reducing the probability of the support assembly 3 tilting, and thus reducing the probability of the battery cell breaking.

[0055] To further illustrate, there are multiple support assemblies 3, each spaced apart along the X-direction, with two adjacent support assemblies 3 supporting one material. For example, there are three support assemblies 3, each comprising a first support assembly, a second support assembly, and a third support assembly. The first, second, and third support assemblies are arranged in sequence, with the first and second support assemblies jointly supporting one material, and the second and third support assemblies jointly supporting one material. The minimum number of support assemblies 3 is two. One end of each support assembly 3 is connected to a first mounting portion 14, and the other end of each support assembly 3 is connected to a corresponding second mounting portion 24.

[0056] The two adjacent support assemblies 3 support the material together, so that the material moves along with the support assemblies 3 in the X direction, thereby realizing the transfer of the material.

[0059] Further, the end face of the support assembly 3 facing the first conveying mechanism 1 and the end face of the support assembly 3 facing the second conveying mechanism 2 are the same end face, and the support assembly 3 is provided with a third mounting portion 31 and a fourth mounting portion 32 on the end face, and the third mounting portion 31 and the fourth mounting portion 32 are arranged along the Y direction at intervals. The third mounting portion 31 is connected with the first mounting portion 14, and the fourth mounting portion 32 is connected with the second mounting portion 24, so as to mount the support assembly 3 on the first conveying mechanism 1 and the second conveying mechanism 2, so that the support assembly 3 can move along the X direction with the first conveying belt 13 and the second conveying belt 23, thereby conveying the materials in the X direction.

The first table 335 is located below the first supporting end surface 333 in the Z direction. When the battery cell is partially located on the first supporting end surface 333, since the first table 335 is lower than the first supporting end surface 333, a gap is formed between the first table 335 and the battery cell in the Z direction; second steps 344 are provided at both edges of the second supporting end surface 343 relative to the X direction, and the second steps 344 form a second table 345.
