Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery aluminum-plastic film rapid packaging machines, in particular to a closed lithium battery aluminum-plastic film rapid packaging machine. Background Art

[0002] With the development of portable electronic products, the demand for lithium batteries, the most important power supply for portable electronic products, is also increasing. Lithium-ion batteries have high working voltage, light weight and long cycle life. The electrolyte of lithium-ion batteries is sealed in aluminum-plastic packaging film, and the aluminum-plastic packaging film must be packaged by an aluminum-plastic film packaging machine. Lithium batteries are primary batteries with lithium metal or lithium alloy as negative electrode materials and non-aqueous electrolyte solutions. They are different from rechargeable batteries, lithium-ion batteries and lithium-ion polymer batteries. The inventor of lithium batteries is Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronics technology at the end of the 20th century, miniaturized equipment has increased, and high requirements have been placed on power sources. Lithium batteries have entered a large-scale practical stage. For example, the application number is 202122696189.0, which is called a lithium battery aluminum-plastic film packaging machine. The device includes a packaging frame and a packaging component, and the packaging component is arranged on the inner side of the packaging frame. The lithium battery aluminum-plastic film packaging machine is provided with an overhead heat-insulating layer in the existing packaging machine. The overhead heat-insulating layer is provided between the heat-conducting oil tank and the packaging machine frame. On the one hand, it affects the heating of the copper head by the heat-conducting oil in the heat-conducting oil tank. On the other hand, the overhead heat-insulating layer is a hollow structure. The heat conductivity of the gas in the hollow structure is poor. Compared with adopting some cooling settings, it can save energy for heating the heat-conducting oil. On the other hand, a corresponding heat-absorbing and heat-dissipating device is provided in the overhead heat-insulating layer. When the temperature is too high, it is started to absorb heat energy and extend the service life of the device. By combining the overhead columns with the load-bearing honeycomb plates, it is ensured that the overhead layer is filled with a large amount of air while leaving space for installing other cooling devices, and the strength of the packaging plate is also ensured.

[0003] During the use of the above-mentioned device, when the rapid packaging machine is plastic-sealing lithium batteries, some defective lithium batteries may have their temperature rise when the surface is heat-sealed, which may cause the lithium batteries to explode. The explosive lithium batteries may affect the surrounding good lithium batteries due to the lack of partition structure, and may even cause the surrounding good lithium batteries to explode as well. Therefore, we have proposed a closed lithium battery aluminum-plastic film rapid packaging machine to solve the above-mentioned problems. Utility Model Content
