The predetermined number mentioned here may be the number of battery pieces included in one battery string, or may be the number of battery pieces included in a plurality of battery strings. As in some welding applications, the welding device only completes the welding of one battery string at a time, and thus in these application examples, the predetermined number referred to refers to the number of battery pieces required to form one battery string. In other welding applications, the welding device performs welding of multiple battery strings in parallel at a time, and thus in these applications, the predetermined number referred to refers to the number of battery pieces required to construct the multiple battery strings.

The stepping platform 20 is configured to be capable of stepping movement toward or away from the fixed platform 30. In the process of feeding the battery pieces, after i battery pieces are fed onto the conveying belt 60, the stepping platform 20 is away from the fixed platform for a predetermined distance until all the battery pieces with a predetermined number are fed onto the conveying belt 60, wherein i is a natural number greater than zero. The predetermined distance of each step of the stepping platform 20 mentioned here matches the length of the i-piece battery piece loaded onto the conveying belt 60 in the conveying direction of the conveying belt.
Through setting up the step platform 20 that can move step by step towards or keep away from fixed platform 30, in the battery piece material loading in-process, every time i piece battery piece of current batch is by material loading to the material loading position on the transmission band 60 after, step platform 20 keeps away from fixed platform step by step predetermined distance promptly to drive transmission band 60 and the material loading to the i piece battery piece of this batch above that step by step predetermined distance of fixed platform of keeping away from synchronously. Therefore, the feeding position close to the feeding station on the conveying belt 60 can be always kept vacant, and smooth feeding of the i-piece battery pieces of the next batch to the feeding position is achieved.

The conveyor belt 60 is mounted on the main drive roller 51, the first guide roller 53 and the second guide roller 54 and tensioned by the tension roller 52.
By adjusting the position of the tensioning roller 52 before the battery sheet is fed, tensioning of the conveyor belt 60 can be achieved, ensuring that the conveyor belt 60 is wound in a tensioned state on the conveyor belt drive 50.

Second embodiment
As shown in fig. 3, in the conveyor belt driving mechanism 50 of the first embodiment, the first guide roller 53 is directly installed at the bottom of the stepping platform 20, i.e., the first guide roller 53 is hidden under the stepping platform 20. With this arrangement, the portion of the conveyor belt 60 wound around the first guide roller 53 is also hidden under the stepping platform 20, which eventually causes inconvenience in the installation and adjustment processes of the conveyor belt 60.
For this reason, it is necessary to further optimize the belt driving mechanism 50 in the first embodiment, and the present embodiment is proposed based on this consideration.
As shown in fig. 4 to 5, the structure and the operation principle of the battery welding and conveying device provided in this embodiment are substantially the same as those of the first embodiment, and there are only differences: in the present embodiment, the first guide roller 53 of the belt drive mechanism 50 is mounted in a different manner from that in the first embodiment.
For the sake of brevity, in this embodiment, we only make a specific description of the differences, and please refer to the related contents in the first embodiment above directly for the rest.
As shown in fig. 4 to fig. 5, the battery welding and conveying device in this embodiment further includes a first guide roller mounting bracket 23, a first end of the first guide roller mounting bracket 23 is connected to the bottom of the stepping platform 20, a second end of the first guide roller mounting bracket 23 extends outward to an end of the stepping platform 20 far away from the fixing platform 30, and a first guide roller 53 is mounted at a second end of the first guide roller mounting bracket 23, so that the first guide roller 53 is located outside the stepping platform 20.
As a preferred embodiment, the first guide roller mounting bracket 23 in the embodiment of fig. 4 to 5 is configured as an L-shaped mounting bracket composed of a vertical portion connected to the bottom of the stepping platform 20 and a horizontal portion extending outward from the end of the stepping platform 20.
As shown in fig. 6, by providing the first guide roller mounting bracket 23 and indirectly mounting the first guide roller 53 at the bottom of the stepping platform 20 through the first guide roller mounting bracket 23, it can be ensured that the first guide roller 53 can extend out to the outside of the stepping platform 20, and thus, the transmission belt wound around the first guide roller 53 can also be exposed at the outside of the stepping platform 20, thereby facilitating the installation and adjustment of the transmission belt.
Third embodiment
The belt driving mechanism 50 of the first and second embodiments includes four roller structures, i.e., a main driving roller 51, a tension roller 52, a first guide roller 53, and a second guide roller 54, and the structure is complicated. In addition, in the first and second embodiments, when the conveying belt 60 passes around the first guide roller 53, the conveying surface (front surface) of the conveying belt 60 directly contacts the first guide roller 53, and therefore, the conveying surface of the conveying belt 60 is easily worn by the first guide roller 53.
In view of the above, the present embodiment provides a conveyor belt driving mechanism with a simpler structure, and with the conveyor belt driving mechanism, the conveying surface of the conveyor belt 60 does not contact with the roller, thereby reducing the wear of the conveying surface of the conveyor belt and prolonging the life of the conveyor belt.
It should be noted that the structure and the operation principle of the battery welding and conveying device provided in this embodiment are substantially the same as those of the first embodiment, and there are only differences: the belt driving mechanism in this embodiment is different in structure from the belt driving mechanism in the first embodiment.
Similarly, for the sake of brevity, the present embodiment only describes the driving mechanism of the belt, and the rest of the description refers to the related contents of the first embodiment above.
As shown in fig. 6 to 8, the conveyor belt driving mechanism 50 of the battery welding and conveying apparatus of the present embodiment includes a main driving roller 51, a guide roller 57, a rotating bracket 58, and a tension roller 59, wherein: the main driving roller 51 is arranged at the end of the fixed platform 30, the guiding roller 57 is connected to the bottom of the base 10, the first end of the rotating bracket 58 is rotatably connected to the bottom of the base 10 and can rotate around the base 10, and the second end of the rotating bracket 58 extends outwards to form the end of the stepping platform 20 away from the fixed platform. A tensioning roller 59 is attached to the second end of the rotating bracket 58.
As shown in fig. 9, the conveyor belt 60 is mounted on the main drive roller 51, the guide roller 57 and tensioned by the tensioning roller 59, and the conveying surface of the conveyor belt 60 is not in contact with any roller, thereby reducing wear of the conveying surface.
The rotating bracket 58 drives the tensioning roller 59 to act to tension the transmission belt 60, which comprises the following steps: rotating bracket 58 is configured to rotate toward stepping platform 20 during stepping of stepping platform 20 away from stationary platform 30, and to rotate away from stepping platform 20 during stepping of stepping platform 20 toward stationary platform 30. In this way, it can be ensured that the conveyor belt 60 is always wound around the conveyor belt drive 50 in a tensioned state.
In order to drive the rotating bracket 58 to rotate, a rotating bracket driving mechanism may be further provided in the present embodiment, and various known driving mechanisms may be adopted in the rotating bracket driving mechanism, such as a driving air cylinder, and the present embodiment is not particularly limited thereto.
It can be seen that in the present embodiment, the driving of the conveying belt can be realized only by providing three roller structures, such as the main driving roller 51, the guide roller 57, and the tensioning roller 59, which makes the structure of the conveying belt driving mechanism 50 simpler.
The invention also provides a battery welding and conveying method, which can be implemented by any battery welding and conveying device in the above embodiments of the invention, and comprises the following steps:
loading i battery pieces onto a conveying belt 60 on a stepping platform 20, wherein i is a natural number greater than 0;
controlling the stepping platform 20 to step for a preset distance in the direction away from the fixed platform;
when the number of the battery pieces on the conveying belt on the stepping platform 20 reaches a preset number, controlling the stepping platform 20 to step towards the fixed platform 30 until the battery pieces reach a position close to the fixed platform;
the conveyor belt 60 is controlled to convey a predetermined number of battery pieces toward the welding station. To perform a subsequent welding operation.
