Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production equipment, in particular to a lithium battery packaging device. Background Art

[0002] The battery is the cell except for the protective circuit board. Lithium battery is a primary battery with lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high requirements on the environment. Flexible lithium batteries have higher flexibility than traditional lithium batteries. Lithium batteries and cell production need to be packaged after assembly.

[0003] After searching, it was found that the announcement number is CN220106584U, and the name is a lithium battery production cell packaging equipment. The application proposes that in the existing equipment, the packaging equipment does not have a buffer structure. During the packaging process, the packaging pressure plate will frequently collide with the base. The impact of the packaging pressure plate on the base will not only produce noise, but also accelerate the damage rate of the base. By setting components such as dampers, placement plates and springs, during the stamping and packaging process, the packaging pressure block squeezes the material and drives the placement plate, and the placement plate then squeezes multiple dampers and springs. The setting of the damper and spring can prevent the base from being directly applied with impact force, which not only has the effect of shock absorption and noise reduction, but also can extend the service life of the base. At the same time, by setting mounting sleeves, threaded columns and packaging pressure blocks, etc. Components, when the punching torque is too large, the distance between the packaging block and the material to be packaged can be extended by rotating the threaded column, so as to achieve the purpose of quickly adjusting the punching torque. At the same time, components such as alarms, central controllers, control panels and pressure sensors are also provided, which can promptly sound an alarm when the torque is too large to ensure the packaging quality of the material. However, the packaging blocks in this application need to be rotated and adjusted one by one during adjustment, which is more troublesome, and it is difficult to ensure that the bottom surfaces of the packaging blocks after adjustment are in the same plane, which easily leads to uneven heights, affecting the accuracy and efficiency of packaging. At the same time, dampers and springs are used for shock absorption in this application. Although the shock absorption effect is good, its structure is more complicated, and maintenance and replacement are more troublesome, and the manufacturing cost is high. Further improvements can also be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
