Description

Technical Field

[0001] The utility model relates to the field of battery manufacturing, in particular to a device for adjusting the fixed pressure and thickness of a horizontal terminal used in battery formation. Background Art

[0002] During the manufacturing process of lithium batteries, lithium batteries need to be continuously charged and discharged to adjust and test the performance of lithium batteries. In the charging and discharging process, a pressing mechanism is generally used. The pressing mechanism includes positive and negative electrode needle plate assemblies that can be opened and closed toward each other. The positive and negative electrode needle plate assemblies are arranged horizontally in mirror images. During charging and discharging, the lithium battery is arranged in the accommodation space between the spacers to form a queue. The probe queue is arranged on the top frame, and the probe queue is located on the left and right of the lithium battery queue. When the needle plate assembly is closed, the probe contacts the pole of the lithium battery to charge and discharge the lithium battery.

[0003] In order to ensure stable and reliable charging and discharging of lithium batteries, it is necessary to pay attention to the stability of the pressing between the battery pole and the probe, that is, the vertical projection position of the probe and the lithium battery pole needs to coincide. If the position of the probe and the lithium battery pole deviates, the probe will not be able to effectively contact the lithium battery pole, affecting the charging and discharging of the lithium battery.

[0004] At the same time, in conventional battery capacity separation equipment, the restraint tray is not compatible with batteries with large deviations in the incoming batteries, and cannot provide a constant pressure for the batteries during operation. Moreover, when the batteries expand during the capacity separation process, they cannot be positioned dynamically, which will affect the displacement of the batteries and the probes, thereby affecting the battery performance and appearance. Traditional conventional capacity separation equipment uses a spray-type fire extinguishing method. After the battery catches fire, an automatic triggering spray system is used to first extinguish the fire with gas and then start water spraying to extinguish the fire. This fire extinguishing method has the problem that the internal heat of the battery cannot be completely reduced, which can easily lead to secondary fires in the battery, thus posing a great safety hazard to the equipment and factory buildings.
