Description

Technical Field

[0001] The utility model relates to the technical field of compression devices, in particular to a compression device for lithium battery capping. Background Art

[0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution. It is different from rechargeable lithium-ion battery and lithium-ion polymer battery. The lithium battery cap pressing device is a device that tightens the top surface of the lithium battery during production. Before the lithium battery sealing process, it must be ensured that the lithium battery cap is pressed in place. The quality of the battery cap tightening determines the service life of the battery. The tightness of the lithium battery cap is also a key factor in whether the lithium battery has good conductivity.

[0003] Publication No. CN211556061U discloses a lithium battery cap pressing device, which structure includes a U-shaped groove, a flip cover, a battery storage groove, a cylinder, a pressure rod, and a pressure block. The cylinder is connected to the pressure block through the pressure rod and is fixed to the upper part of the flip cover. One end of the flip cover is movably connected to one end of the upper part of the U-shaped groove. The battery storage groove has a plurality of grooves. The lower part of the flip cover has depressions corresponding to the number and positions of the plurality of grooves. The pressure block extends into the depressions. When the utility model is in use, the battery to be processed is loaded into the battery storage groove, and then the battery storage groove is pushed into the U-shaped groove, the flip cover is closed, and the cylinder is started to drive the pressure block to press the lithium battery cap. After the pressing is completed, the flip cover is opened, the battery storage groove is pushed out of the U-shaped groove, and the next stage of processing can be carried out. The utility model has a simple structure, can process multiple batteries at the same time, and can be processed continuously, which greatly improves the production efficiency. Although the clamping device can process multiple batteries at the same time, after processing, the staff needs to take them out manually one by one. The compressed lithium batteries are not easy to take out from the U-shaped groove, which needs to be improved. Utility Model Content
