[0002] Lithium-ion batteries are divided into square lithium batteries (such as commonly used mobile phone battery cells), cylindrical lithium batteries (such as 18650, 18500, etc.) and button lithium batteries according to their appearance; lithium batteries are divided into aluminum shell lithium batteries, steel Shell lithium battery, soft pack battery; divided into lithium cobalt oxide, lithium iron phosphate, lithium manganese oxide, and lithium polymer according to the positive electrode material; in this article, a square battery refers to a lithium battery with a square shape and a metal case; After the liquid injection of the square battery is completed, the liquid injection hole needs to be sealed to prevent the electrolyte from overflowing. The sealing process needs to be tightly sealed. The previous process is relatively simple in operation, and one device is operated in each step, continuously The performance is not very good, and the work efficiency is not high. The present invention expects to seek a sealing device with a high degree of automation to improve production efficiency.

The invention relates to automatic sealing equipment for electrolyte injection holes of square batteries, which comprises an operating platform (1), a circular groove (2) arranged in the middle of theoperating platform, a square turntable (3) arranged in the middle of the circular groove (2) and four clamping devices arranged on the square turntable (3) for fixing square batteries (3). The automatic sealing equipment further comprises a battery shift-in device (5), a steel ball transfer device (6), a stamping device (7) and a battery shift-out device (8) which are installed around the squareturntable. The central idea is to design a turntable, wherein the turntable is provided with the square battery fixing devices thereon, the edge of the turntable is provided with the square battery transfer device, the round steel ball injection device and the stamping device, the turntable rotates by an angle, and the four devices simultaneously work, so that the production efficiency is very high. In addition, the overall equipment is concentrated in the same place, thereby extremely saving the occupied space.
