The shape of the crimp body 12 is cylindrical, and the cylindrical crimp body 12 is placed in the first circular cavity 4 to protect the crimp body 12 from being flattened; the extended tab 11 is received in the second circular cavity 5 to avoid buckling or flattening. The loading part can be made of plastic or metal material, and the plastic piece can be molded at one time by injection molding. The loading part has the advantages of simple structure, convenient processing and low manufacturing cost.

As shown in fig. 1 and 2, the diameter of the first circular chamber 4 is larger than the diameter of the second circular chamber 5. Since the negative electrode tab 111 of the crimp 1 is located at the inner side position of the crimp body 12, not at the outermost surface position, the caliber of the second circular cavity 5 may be smaller than that of the first circular cavity 4. The second circular cavity 5 is circular, so that the coiled 12 body is convenient to insert, the direction is not restricted, the loading process is easy to control and realize, and the production efficiency is improved. The depth of the first circular cavity 4 is less than the height of the crimp body 12 and the depth of the second circular cavity 5 is greater than the length of the tab 11. After the wound product 1 is mounted on the mounting member 8, the upper half of the wound body 12 and the positive electrode tab 112 are exposed, and when the wound product 1 is transported to the next step, the upper half of the wound body 12 is gripped by the gripping means and lifted upward, and the wound product 1 is taken out from the mounting member.

In the extended state of the tab 11, the depth of the second circular cavity 5 is sufficient to prevent the tab 11 from being crushed or bent.

As shown in fig. 3-7, the directional conveying mechanism of the battery curls 1 comprises a rotary table 6 capable of continuously rotating, more than three conveying positions capable of accommodating the loading parts 8 are arranged on the periphery of the rotary table 6, the first conveying position 71 is used for accommodating the loading parts 8, the second conveying position 72 is used for accommodating the curls 1 in the loading parts 8, and the loading parts 8 with the curls 1 are pushed away from the rotary table 6 from the third conveying position 73; the loading part 8 comprises a base body 3, at least one end of the base body 3 is provided with a first circular cavity 4 for accommodating a crimping body 12, a second circular cavity 5 for accommodating a tab 11 is arranged in the base body 3 below the first circular cavity 4, and the first circular cavity 4 is communicated with the second circular cavity 5.

As shown in fig. 2, the first circular cavities 4 are arranged at both ends of the loading part 8, so that the design of the conveying mechanism can be reduced and the flow process can be simplified without paying attention to the forward and reverse directions of the loading part 8 during the conveying process.
