Description

Restraint tray Technical Field The utility model relates to the technical field of battery trays, in particular to a restraint tray. Background In the production process of the battery cells, a restraint tray is often used for carrying out batch processing on dozens of battery cells. The restraint tray is used for stably fixing the battery cell, so that links such as insertion of the liquid injection needle into the liquid injection hole, contact of the probe with the pole terminal and the like are ensured to be smoothly carried out. In addition, the restraint tray is also responsible for applying proper pressure to the large surface of the battery cell, so that the pole piece is better contacted with electrolyte in the formation link of the battery cell, and the uniform formation of the solid electrolyte interface film is promoted. In the related art, the used restraint tray is fixed in structure in the production process of the battery cells, on one hand, the tray can only be suitable for the production of the battery cells with single thickness dimension, when the production requirements of the battery cells with different thicknesses are met, the tray is required to be replaced or manufactured again, the production cost and the time consumption are increased, and on the other hand, the restraint tray with fixed structure is difficult to exert an effective restraint effect on the large surface of the battery cells, and the performance of the battery cells is influenced.
