Problems solved by technology

[0003] (1) The existing lithium battery liquid injection device not only has poor liquid injection efficiency when performing liquid injection operations on lithium batteries, but also has high requirements on the size of lithium batteries, which is inconvenient for quick adjustment of height and angle;
[0004] (2) The existing lithium battery liquid injection device needs to be fixed and limited by the operator to prevent the lithium battery from moving during liquid injection, but it will increase the workload of the operator and is inconvenient Quickly limit the lithium battery; therefore, the above problems need to be improved

Embodiment 1

[0028] Embodiment 1: see Figure 1-6 , a lithium battery liquid injection device, including a base 1, a linkage mechanism, a clamping mechanism, a drive assembly, a buffer assembly and a transmission assembly, the base 1 is a rectangular plate-shaped horizontally arranged, and the middle parts on both sides of the top surface of the base 1 are vertical The fixed columns 2 are fixed, and the middle part of the top surface of each fixed column 2 is vertically fixed with a threaded rod 3, and the thread direction on the surface of the threaded rod 3 is set in the opposite direction; horizontal beams 4 are arranged between the threaded rods 3, and the beams 4 Both sides of the top surface of the top surface are provided with mounting ports vertically, and a threaded barrel 5 is vertically movable in each mounting port, and the top and bottom of the outer wall of each threaded barrel 5 are fixedly sleeved with first bearings, and each threaded barrel The outer ring of 5 is fixedly ...

Embodiment 2

[0035] Embodiment 2: In this embodiment, the present invention also proposes a method for using a lithium battery liquid injection device, comprising the following steps:

[0036] Step 1, firstly fix the liquid injection instrument 8 on the bottom end of the fixed shaft, then electrically connect the motor 6, the electric push rod, the single-chip microcomputer, the electric push rod and the electric push cylinder 24 to an external power supply through wires respectively, and connect the The lithium battery to be filled is placed on the lifting plate in the placement tank;

[0037] Step 2, when the position of the liquid injection tube of the liquid injection instrument 8 needs to be adjusted according to the position of the liquid injection hole of the lithium battery, the lifting plate 22 is driven to lift in the transmission box 7 by controlling the expansion and contraction of the electric push cylinder 24, and the lifting plate The lifting of 22 is convenient to drive the...
