[0030] In addition, if the terms "first", "second" and the like are used only to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0032] With the continuous development of the battery industry, cylindrical battery cells have become a mainstream. The cylindrical battery cell has the following advantages compared with other battery cells: 1) good consistency of a single one, can be mass-produced; 2) high temperature resistance of cylindrical lithium battery, safe and not easy to explode, and good mechanical properties of a single cylindrical battery cell. Compared with square batteries and soft package batteries, the closed cylindrical battery can obtain higher bending strength under the same size; in addition, the sealing performance of the cylindrical battery is good, not easy to explode, and the cost is low. 3) high energy density, small single energy, easy to control when a safety accident occurs. 4) small internal resistance, greatly reducing the self-consumption of the battery, increasing the endurance of the battery. 5) wide range of applications, applied to laptop computers, handheld interphones, portable disc machines, instrument and meter equipment, sound equipment, model airplanes, digital video cameras, lighting equipment, children's toy enterprise products, pneumatic tools and other electronic equipment. At present, on the automatic production line of most cylindrical battery cells, the battery cell needs to be turned over for assembly during some processes.

[0033] In the battery production process, the battery cell needs to be turned over and adjusted to be loaded into the shell. However, the battery cell may generate debris during the turning process, and the surface of the battery cell may also adsorb impurities, which will affect the subsequent welding process, affect the processing quality, and further affect the performance of the battery. The battery cell in the embodiment mainly refers to a cylindrical battery cell, but is not limited to a cylindrical battery cell, and can also be a square battery cell or a soft package battery cell.

[0034] Based on this, please refer to Figure 1 、 Figure 2 and Figure 3The technical problems mentioned above can be effectively improved by the cell overturning device 100 provided in the embodiments of the present application. The cell overturning device 100 can remove dust on the cell, remove impurities on the surface of the cell and debris generated in the overturning process, and ensure the quality and performance of subsequent battery production. Moreover, the cell overturning device 100 has a simple structure. The cell overturning device 100 can be applied to the cell production line 1000, and the equipment or production line with the cell overturning device 100 has the same functions mentioned above, which will not be repeated here.

[0035] Figure 1 The present application provides a first perspective view of the cell production line 1000 provided in the embodiments of the present application. Figure 2 The present application provides a second perspective view of the cell production line 1000 provided in the embodiments of the present application. As shown in Figure 1 and Figure 2 The present application provides a cell production line 1000 provided in the embodiments of the present application, which comprises a cell overturning device 100 and a conveying device. The cell overturning device 100 is arranged on the side of the conveying device. The cell overturning device 100 can clamp and overturn the cells transported on the conveying device, and then put them back on the conveying device after dust removal, so as to perform the next process. Of course, the cell production line 1000 can also comprise a winding device, a rolling device and the like, so as to realize multiple processing steps in the cell production process, which will not be limited here.

[0036] In the cell production process, multiple cells often need to be matched in groups for production. In the prior art, each cell is usually overturned individually. This production method is easy to cause the relative positions of multiple cells to deviate, which affects the processing accuracy of subsequent production and thus affects the quality of the cells. Moreover, multiple cells cannot be overturned simultaneously, which causes low production efficiency. In order to simultaneously overturn multiple cells and improve production efficiency, the number of the cell overturning device 100 in the present embodiment is multiple, and multiple cell overturning devices 100 are arranged at intervals. Multiple cell overturning devices 100 can simultaneously overturn multiple cells, which improves the production efficiency. Multiple cell overturning devices 100 in the present embodiment are arranged in parallel and at intervals. By arranging multiple cell overturning devices 100 on the same horizontal line, the relative positions of multiple cells after overturning can be ensured not to deviate, so as to improve the processing accuracy of subsequent production and ensure the quality of battery production.

One end of the dust removal pipe 130 is used for being connected with an external dust removal machine. The other end of the dust removal pipe 130 is used for cleaning the electric core and the clamping assembly 110 in the case that the dust removal machine is started. After the clamping assembly 110 stably clamps the electric core, the rotating assembly 120 drives the clamping assembly 110 to rotate, so as to overturn the electric core to the required angle for installation. Then the dust removal pipe 130 is connected with the dust removal machine, and the dust removal machine is started, so that the dust removal pipe 130 cleans the electric core and other structural members of the electric core overturning device 100, so as to remove the impurities and the debris generated in the overturning process on the electric core and the electric core overturning device 100, so as to facilitate the subsequent processing of the electric core, thereby ensuring the quality and performance of the battery. The end of the dust removal pipe 130 for cleaning the electric core and the clamping assembly 110 can be directly aimed at the electric core and the clamping assembly 110 for cleaning.
