Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery vacuum sealing, and in particular relates to a lithium battery vacuum sealing device. Background Art

[0002] Lithium battery is a rechargeable battery that uses lithium ions as positive and negative electrode materials. It has the advantages of high energy density, long cycle life and lightweight, and is widely used in mobile devices, electric vehicles, energy storage systems and other fields. During production and use, lithium batteries need to be packaged to ensure their safety and stability. When lithium batteries are formed, they will produce gases. These gases (such as HF, CO, CO2, NO, etc.) will affect the performance and life of the battery, causing the battery to swell. When sealing, the battery fluid will be discharged, the battery capacity will be reduced, and the gas will affect the activity of the battery fluid, which will ultimately affect the service life of the battery. Therefore, lithium batteries should be vacuumed before sealing.

[0003] The existing patent announcement number is CN201478346U, and the public name is a lithium battery vacuum sealing machine, which includes a controller, a vacuum device and a sealing device, wherein the vacuum device includes a vacuum pressing cylinder, an upper vacuum pressing strip connected to the pressure head of the vacuum pressing cylinder, a lower vacuum pressing strip fixed on the machine body opposite to the upper vacuum pressing strip, a vacuum hose and a vacuum pump connected to the vacuum hose; the sealing device consists of a head cylinder, a heat sealing head connected to the head cylinder, and a heat sealing head leveling silicone strip arranged on the machine body opposite to the heat sealing head; the heat sealing head and the heat sealing head leveling silicone strip are arranged on the sides of the upper and lower vacuum pressing silicone strips.

[0004] Although the above-mentioned vacuum sealing machine can place the battery cell seal from the side between the seal head and the vacuum strip when processing the battery, vacuumization is performed first and then sealing, and the uneven areas on the battery cell surface are manually processed in time to ensure the quality of the battery. In addition, the vacuumization of large batteries will not be limited by the volume of the vacuum chamber in the prior art, thereby reducing the processing cost of large batteries. However, the above-mentioned vacuum sealing machine is not convenient for tightening the limit and centering the battery when processing the battery, and the battery will be offset during the sealing process, thereby causing an offset between the battery and the sealing machine, and then the vacuumization and sealing effects are poor.
