Abstract

The invention belongs to the technical field of lithium ion batteries, and particularly relates to a lithium ion battery efficient liquid injection device which comprises a base, a vacuum standing boxfixed to the left side of the base, a right side fixing support, a liquid injection frame fixed to the support, a liquid injection clamp arranged below the liquid injection frame, a battery cell arranged in the liquid injection clamp, and a stroke motor fixed to the liquid injection frame through a template. A liquid injection head fixing base is arranged on the stroke motor, a rotating screw rodmoving up and down is arranged in the center of the liquid injection frame, and two movable fixing rods are arranged on the liquid injection frame on the two sides of the rotating screw rod. The problems that large battery liquid injection is difficult and large battery bulging and electrolyte spraying are caused by liquid injection can be effectively solved, and remote battery carrying is avoided due to the integrated design of the liquid injection device and the vacuumizing device; the liquid injection clamps of the battery cells of different specifications can be replaced by controlling the rotary screw rod according to the size of the battery; and the relative position between the lithium battery cell and the liquid injection clamp can be adjusted by controlling the stroke motor according to the number of batteries, multiple batteries can be injected at a time, and the liquid injection efficiency is improved.

Description

Technical field[0001]The invention belongs to the technical field of lithium ion batteries, and specifically relates to a high-efficiency lithium ion battery liquid injection device and a battery liquid injection method thereof.Background technique[0002]At present, lithium batteries use the traditional mode of liquid injection, which is difficult to inject for batteries with a height of more than 300 meters, and the existing lithium ion battery injection device cannot be moved, and the operation is difficult when large batteries are injected. The spacing of the injection clamps is fixed. The liquid injection device cannot be adjusted with the size of the battery. Sometimes when the size of the lithium battery does not match the liquid injection fixture, manual injection is required. After the injection is completed, the battery cell needs to be moved to the vacuum box to vacuum and stand still. Laborious. In addition, the traditional battery injection method is to apply positive pre...
