The invention relates to a square battery liquid injection machine, which comprises an electrolyte solution storage box (10), a liquid injection system (20) and a vacuum pumping system (30). The liquid injection system (20) and the vacuum pumping system (30) are in integrated combination. The liquid injection system (20) comprises a hibar pump (21), a liquid injection machine body (22) and a liquid injection fixture (23). The hibar pump (21) is connected to the tail end of the liquid injection fixture (23) through a liquid outlet pipe (40). The liquid injection machine body (22) includes a mobile frame (221) and a mobile frame driving device able to make the mobile frame (221) do horizontal movement. The mobile frame (221) is provided with a vertical moving mechanism (222) able to moving vertically. The vacuum pumping system (30) subjects the well injected liquid injection fixture (23) to positive and negative pressure exchange so to make the electrolyte solution rapidly enter a square electrical core aluminum shell (50). The combined integrated design of the liquid injection system and the vacuum pumping system is in favor of fast injection of the electrolyte solution.
Description
technical field [0001] The invention relates to a battery production equipment, more specifically, to a battery liquid injection machine for filling electrolyte solution for a square battery. Background technique [0002] With the continuous development of modern society, mobile devices such as smartphones, tablet computers, laptops, cameras, and hybrid electric vehicles and pure electric vehicles will use lithium-ion batteries more and more widely, and lithium-ion battery injection equipment will also follow With the progress of society, it is also constantly improved. In the past, 1Ah batteries were generally injected with a high-yield suction-type liquid injection machine. The disadvantages are that the minimum number of operators is 3-4, the injection volume is unstable, the electrolyte is wasted, and the surface of the aluminum shell is corroded. It is suitable for the liquid injection of large power batteries above 10Ah-20Ah; while the investment cost of fully automat...
