Currently, the application of power batteries is more widespread from the development of market situation. The power battery is not only applied to energy storage power supply systems such as hydraulic power, firepower, wind power and solar power stations, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric automobiles, and the like, and a plurality of fields such as military equipment, aerospace, and the like. With the development of electric vehicles, military equipment, aerospace and the like, batteries are becoming key to the sustainable development of the automotive industry. Battery technology is an important factor in the development of electric vehicles, military equipment, aerospace, and the like.
The inventor notes that in the existing battery cell formation fixture, when the existing square battery cell is injected, the battery cell is placed in a bushing, then the battery cell with the bushing is placed in a clamping mechanism, the position of the battery cell is fixed, and then the vacuum injection is performed. The side of bush is "protruding" style of calligraphy, and the both shoulders of electric core are exposed to its both shoulders position, and the position of exposing of electric core is used for going up unloading manipulator to snatch electric core, and sets up the purpose of bush for electric core change type is convenient, when the electric core model that needs annotate the liquid changes, only need change the bush of corresponding size can, and the clamping part need not change. The existing arrangement mode has a plurality of problems: firstly, the process of filling pressure gas into the battery cell exists in the liquid injection process, and the process can lead the battery cell to generate plastic deformation, so that when the battery cell is grabbed by the feeding and discharging manipulator and is extracted after the liquid injection is finished, friction exists between the battery cell and the bushing, and the surface of the battery cell can be scratched; secondly, as the space for grabbing by the feeding and discharging mechanical arm is reserved on the side wall of the bushing, the battery cell is subjected to plastic deformation in the liquid injection process, and the surface of the battery cell is uneven; moreover, since the cell cannot be deformed too much, when the cell is put into the bushing, the gap between the bushing and the cell is not large, which requires high positioning accuracy of the loading and unloading manipulator.
Based on the above consideration, in order to solve the above problems, the applicant has designed a battery cell formation fixture and a battery cell formation system through intensive studies, which not only can adjust the depth of the accommodating space for accommodating the battery cells to adapt to battery cells with different sizes (such as battery cells with different heights), but also can effectively improve the universality of the battery cell fixture and greatly reduce the die opening cost and the material management cost.
