The invention discloses an
electrolyte injection device in a
lithium ion battery, relates to the technical field of
lithium battery production, and includes a
workbench, a conveying mechanism, a positioning mechanism, a clamping mechanism and a
liquid injection mechanism, wherein the conveying mechanism is arranged on the
workbench The upper side is used to realize the delivery before and after the
lithium battery injection. The delivery mechanism includes a support plate and a
drive motor. The positioning mechanism is located on the lower side of the delivery mechanism and is used to realize the positioning of the
lithium battery injection. The positioning mechanism includes a
telescopic cylinder. , Hinge strip 1, Hinge strip 2, and positioning strip. The clamping mechanism is located on the upper side of the conveying mechanism and is used to clamp the
lithium battery when liquid is injected. The clamping mechanism includes an overhang strip, a clamping plate, and a hinge strip 3. , a linkage column and a linkage strip. The
liquid injection mechanism is arranged on the upper side of the clamping mechanism and is used to realize the
liquid injection of the
lithium battery. The liquid injection mechanism includes a
hydraulic cylinder and an
electrolyte tank. In summary, the present invention can realize automatic delivery, automatic positioning, automatic clamping and automatic filling of lithium batteries.
