Abstract

The invention discloses a multi-process integrated device for a lithium battery. The multi-process integrated device comprises a lifting device, a jig and a battery cell positioning clamp for positioning lithium battery cells. The lifting device comprises a power piece and a moving piece, wherein the power piece is used for driving the moving piece to lift. The jig comprises a main body, wherein the main body is hung on the moving piece and provided with fluid holes, injection nozzles and conductive pins which correspond to the battery cells one to one; the fluid holes are communicated with the injection nozzles; and all fluid holes are connected in series to form a fluid pipeline used for connecting a fluid injection system. The jig also comprises a steel ball delivery mechanism for delivering steel balls to the injection nozzles, wherein the steel ball delivery mechanism is arranged on the main body. The battery cell positioning clamp is provided with conductors used for connecting battery cell shells in series. By virtue of the multi-process integrated device, the manufacturing technology of the battery cell can be greatly improved, multiple processes such as baking, fluid injection, formation, opening sealing and capacity grading can be finished on one device, the processes are greatly simplified and the battery cell quality is enhanced.

Description

technical field [0001] The invention relates to an integrated machine for battery drying, liquid injection, formation, sealing and volume separation. Background technique [0002] The lithium battery (battery core) includes a shell, a core and an electrolyte. The shell includes a shell and a cap. The cap has a rivet (electrode) insulated from the cover (a part of the shell), and the shell seals the core and the electrolyte. , the winding core is wound together by the positive electrode sheet, the diaphragm, and the negative electrode sheet. For aluminum shell batteries, the positive electrode sheet is connected to the casing from the inside through the positive connecting conductor, and the positive electrode of the winding core is led to the casing, and the negative electrode sheet is connected to the casing through the negative connecting conductor. It is connected with the rivet (electrode) of the cap, and the negative pole of the winding core is drawn out of the battery ...
