Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a lithium battery tray restraint release mechanism. Background Art

[0002] The restraint battery tray is a device specially used in the lithium battery formation process. It is mainly used to maintain the consistency of battery size, especially in the assembly line process of automated battery production. When the battery cell swells in shape due to poor raw materials, poor electrolyte, etc. in the formation process, the restraint battery tray can correct it by applying pressure to ensure the accuracy of the battery size, thereby avoiding affecting the assembly of subsequent processes.

[0003] The utility model patent with the authorization announcement number CN218957801U discloses a portable restraint tray for lithium batteries, which includes a restraint tray shell, a plurality of battery separators, a plurality of battery separators arranged at intervals in the restraint tray shell, and a restraint structure, wherein the restraint structure includes an adjustment restraint plate and an adjustment rod, wherein the adjustment restraint plate is arranged parallel to the battery separator, the adjustment restraint plate is arranged between the battery separator and the end surface fixing plate of the restraint tray shell, the adjustment rod sequentially penetrates the end surface fixing plate and the adjustment restraint plate, the adjustment rod is threadedly connected with the end surface fixing plate, and the adjustment rod is rotationally connected with the adjustment restraint plate. The restraint structure is rotationally connected between the adjustment rod and the adjustment restraint plate, and the adjustment rod is threadedly connected with the end surface connecting plate, so as to realize the control of the adjustment rod on the adjustment restraint plate, so that the adjustment restraint plate can move to press the battery separator and loosen the battery separator respectively, thereby realizing the purpose of flexible restraint of lithium batteries of different models in the process of disintegration and capacity division.

[0004] Although the portable restraint tray for lithium batteries is convenient for flexible restraint of different models, the device still has the following shortcomings in actual use. Specifically, multiple partitions of the device are installed between the restraint plates. When the number of restraint spaces between the partitions needs to be adjusted during the production process, the restraint plates on both sides have to be disassembled and then the partitions are removed from the guide rods. Then, the number of partitions is readjusted according to actual conditions. This disassembly method is time-consuming and labor-intensive. In view of this, we propose a lithium battery tray restraint release mechanism. Utility Model Content

[0039] When it is necessary to remove the excess restraint plate 13, the user first holds the adjustment knob 152 and turns it. The adjustment knob 152 drives the transmission shaft 15 to rotate. As the transmission shaft 15 rotates, the two connecting plates 16 move synchronously inward relative to each other in the cavity 131. The limiting rods 161 at both ends of the connecting plate 16 disengage from the limiting holes 1431 at the same time, and the restriction of the limiting rod 161 on the insert block 143 is released.
