Description

Technical Field

[0001] The utility model relates to the technical field of negative electrode material packaging, in particular to a vibration compacting device for packaging negative electrode materials of lithium batteries. Background Art

[0002] Lithium-ion batteries are rechargeable batteries that rely primarily on the movement of lithium ions between the positive and negative electrodes. During the charge and discharge process, lithium ions are intercalated and deintercalated between the two electrodes. Batteries, which generally use materials containing lithium as electrodes, are the epitome of modern high-performance batteries. Currently, lithium-ion battery negative electrode materials are packaged in drums. Because the bulk density of lithium-ion negative electrode materials is generally low, at 0.4-0.5g / cm³, and the bulk density varies across different sizes, mass production requires that each drum contain essentially the same material mass. Consequently, lighter-density materials cannot be packaged in drums of the same volume.

[0003] For example, the patent document with the announcement number CN207683810U discloses a vibration compaction device for packaging lithium battery negative electrode materials, including a platform, a base, a vibration motor, a shock-absorbing pad and a clamping component; the shock-absorbing pad includes a first shock-absorbing pad and a second shock-absorbing pad; the clamping component includes a long bolt, a locking nut, a pressure plate and a sleeve; the base includes a top plate, a bottom plate and a support column; the two ends of multiple support columns are vertically connected to the top plate and the bottom plate respectively; the long bolt passes through the U-shaped notch of the top plate, the inner hole of the first shock-absorbing pad, the U-shaped notch of the platform, the inner hole of the sleeve and the inner hole of the pressure plate in sequence and is then locked by a locking nut; the vibration motor is placed between the multiple support columns and connected to the top of the bottom plate; the screw passes through the countersunk hole and through hole of the second shock-absorbing pad and is inserted into the first threaded through hole of the bottom plate from the bottom end of the bottom plate. In the prior art, the fixing of the packaging barrel still requires manual fixing of the pressure plate, which is labor-intensive and has low work efficiency. Utility Model Content
