Problems solved by technology
During the manufacturing and processing of lithium batteries, the electrolyte needs to be injected through the liquid injection hole on the battery. The current injection mode mainly adopts the rotary disc type, but due to structural limitations, the efficiency is low, the leakage rate is high, and the electrolyte contacts The time in the air is too long, it is easy to absorb the moisture in the air, resulting in the failure of the electrolyte, which affects the quality, safety, consistency and service life of lithium-ion batteries
At the same time, the amount of liquid injection will directly affect the performance of the battery: too little liquid injection will reduce the battery capacity and the number of rechargeable cycles; too much liquid injection will easily cause the battery to bulge, resulting in battery thickness. Poor; uneven liquid injection will lead to unstable battery performance and potential safety hazards

The invention discloses a liquid-injecting mechanism used for liquid injecting to lithium ion batteries. The liquid-injecting mechanism comprises a floor stand, a sliding bracket, at least one liquid-injecting unit and cylinders. The sliding bracket is arranged on the floor stand in an up-and-down sliding manner, the liquid-injecting unit and the cylinders are mounted in the sliding bracket. The liquid-injecting unit comprises a liquid-injecting cup and a liquid-injecting rod, and the liquid-injecting cup is fixed on the sliding bracket and the bottom of the liquid-injecting cup is provided with a liquid outlet port communicated with exterior. One end of the liquid-injecting rod extends into a cavity in a sealing manner and is used for opening or blocking the liquid outlet port in the up-and-down sliding manner. The output ends of the cylinders are connected with the liquid-injecting rod and drive the same to slide in the liquid-injecting cup. Correspondingly, the invention further discloses a liquid-injecting machine provided with the liquid-injecting mechanism. By the aid of the liquid-injecting machine, liquid can be injected evenly without leakage, and liquid injection efficiency and good yield rate are high.
Description
technical field [0001] The invention relates to a battery liquid injection machine, in particular to a liquid injection mechanism used in the battery liquid injection machine. Background technique [0002] Lithium-ion batteries have the advantages of high energy, high battery voltage, wide operating temperature range, long storage life and small size, and have been widely used in military and civilian small electrical appliances. [0003] Lithium batteries need to go through a liquid injection process during the production process. Liquid injection refers to vacuumizing the formed lithium battery casing before filling it with electrolyte, so that the electrolyte completely wraps the battery core. As one of the important raw materials that determine the performance of lithium batteries, the electrolyte has strict requirements on liquid injection efficiency, liquid injection sealing and liquid injection anti-corrosion devices due to its volatility and irritation. During the ...
