Description

Battery liquid filling mouth cleaning device Technical Field The utility model relates to the technical field of lithium ion battery manufacturing equipment, in particular to a cleaning device for a battery liquid injection port. Background In the process of manufacturing lithium ion batteries, electrolyte injection (simply referred to as "injection") is a critical process. The quality of electrolyte injection is directly related to the electrochemical performance, safety performance and service life of the battery. However, in actual production, a small amount of electrolyte often remains in the region of the liquid injection port after the injection of the electrolyte. Because the electrolyte has stronger corrosiveness, the residue on the surface of the battery shell can cause corrosion damage to shell materials, especially aluminum shells or aluminum plastic films, and even lead to perforation and sealing failure of the shell when serious, thereby causing potential safety hazards such as leakage, short circuit, bulge and the like. In addition, the residual electrolyte also can interfere the subsequent welding and sealing process of the battery, so that the quality and sealing effect of welding spots are affected, and the consistency and the yield of the battery are reduced. Therefore, the cleaning link after the battery liquid injection is completed is particularly important. At present, a manual wiping mode is generally adopted in the industry, namely, a worker cleans the periphery of a liquid injection port by using non-woven fabrics or other adsorptive materials so as to remove electrolyte residues. The method has the advantages of low technical threshold, less equipment investment, low efficiency and multiple non-negligible defects of firstly high manual operation strength, inapplicability to the rhythm of a large-scale continuous production line, high cleaning quality, poor stability, volatility and certain toxicity of electrolyte, easiness in causing health damage to operators due to long-time manual contact, and inconvenience in safe production management, and thirdly difficult standardization and datamation of repeated manual operation, and is not in line with the trend of intelligent upgrading of the current manufacturing industry. In order to solve the above technical problems, the prior art provides an automatic wiping device, which solves the problems of high manual operation strength and inapplicability to the rhythm of large-scale and continuous production, however, most of the existing automatic wiping devices on the market adopt a threaded connection mode or other structures such as a buckle and a plug-in type. Although the structure can meet the replacement requirement to a certain extent, the problems of complicated replacement steps, high alignment difficulty and long time consumption generally exist, the quick switch of the production line is not facilitated, and the overall production beat and the operation efficiency are affected. Therefore, how to realize efficient, stable and automatic cleaning of the residual electrolyte at the liquid injection port, optimize the structure of the wiping head, simplify the replacement process and shorten the replacement time becomes a technical problem to be solved urgently. Disclosure of utility model The utility model mainly aims to provide a cleaning device for a battery liquid injection port, which aims to realize efficient, stable and automatic cleaning of residual electrolyte in the liquid injection port, optimize a wiping head structure, simplify a replacement process and shorten a mold replacement time.
