[0001] The utility model relates to the technical field of lithium battery assembly, in particular to automatic assembly equipment for lithium battery negative electrodes. Background Art

[0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as positive / negative electrode material and a non-aqueous electrolyte solution. The positive and negative electrodes of a lithium battery are round, cap-shaped metal sheets located at both ends of the battery. Therefore, a lithium battery negative electrode automatic assembly device is needed to assemble the positive and negative electrodes of the lithium battery for subsequent use and processing of the lithium battery.

Then the first electric push rod 33 pushes the upper pressure plate 32 to move downward and the second electric push rod pushes the lower pressure plate 31 to move upward, so that the lower pressure plate 31 and the upper pressure plate 32 move relative to each other, so that the lithium battery and the negative electrode sheet are squeezed by the upper pressure plate 32 and the lower pressure plate 31 to complete the installation of the lithium battery, and then the lithium battery and the negative electrode sheet are welded to complete the assembly of the negative electrode of the lithium battery, and then the first electric push rod 33 and the second electric push rod retract to complete the opening of the lower pressure plate 31 and the upper pressure plate 32, so as to take out the assembled lithium battery.

[0028] refer to Figure 1 , Figure 2 and Figure 4 As shown, a limit stabilization component 4 includes a slide groove opened on the mounting base 1 and a connecting plate 41 slidably installed on the slide groove, and a detachable pushing plate 42 is provided at one end of the connecting plate 41; a power component is provided inside the slide groove, and the power component includes a screw rod 44 rotatably installed inside the slide groove and a motor installed on one side of the mounting base 1, and an adjustment seat 43 is sleeved on the screw rod 44, and the top of the adjustment seat 43 is connected to the bottom of the connecting plate 41, and the motor is used to drive the screw rod 44 to rotate; a limit component is also provided inside the slide groove, and the limit component includes two guide rods 45 fixed inside the slide groove, and the screw rod 44 is located between the two guide rods 45, and the two guide rods 45 both pass through the adjustment seat 43.
