[0002] In the design of lithium - ion battery windings, for some batteries with larger thickness, two or more cores need to be designed in the same housing. Due to the limitations of battery design and winding technology, there are corresponding differences in the positions of the positive and negative electrode tabs of the two cores. The two cores are respectively called core A and core B. Since the same machine of the cutting and winding equipment outputs one type of core, while the assembly line requires two types of cores at the same time.
[0003] For most production lines, usually multiple cutting and winding lines are matched with multiple assembly lines. Therefore, a special mechanism needs to be set up to pair core A and core B to meet the requirements of the assembly line for cores. Content of the Utility Model

The logistics system transports core A and core B to a preset blanking position. The steering robot turns core A or core B so that the same - pole electrode tabs of core A and core B face each other, facilitating subsequent welding process.

The blanking position of line A is set on the A assembly line, and the blanking position of line B is set on the B assembly line. The A conveyor line is connected to the core - cutting machine on line A, and the B conveyor line is connected to the core - cutting machine on line B.
[0009] Furthermore, there are two core - cutting machines on line A and line B respectively, which increases the production speed of core A and core B.
[0010] Furthermore, there are two A assembly lines and two B assembly lines respectively, and two groups of blanking positions are correspondingly provided, which increases the speed of core matching.
[0011] Further, a traversing device for conveying the A core to the A assembly line is provided on the A conveyor line; a traversing device for conveying the B core to the B assembly line is provided on the B conveyor line.
[0012] Further, a photoelectric sensor is provided at the traversing device to facilitate monitoring whether there is a core that needs to be transported to the assembly line at the traversing device.
[0013] Further, conveying robotic arms are provided at the A assembly line and the B assembly line, enabling the flexible layout of the assembly line and reducing the floor area of the production line.
[0014] Further, a first positioning device is provided at the positions corresponding to the conveying robotic arms on the A assembly line and the B assembly line to position the cores, facilitating the operation of the conveying robotic arms.

At the loading position, a loading robotic arm for placing the A core and the B core at the second positioning device is provided. The loading robotic arm positions the cores, facilitating the operation of the turning robotic arm.
