摘　　要：为解决电池包装机中吸头对封套的吸附不稳定而影响整机的包装效率的问题。通过封套受力理论分析得到吸头性能的评价指标,运用Fluent软件对不同结构参数吸头的流场进行数值模拟正交试验,并对结果进行分析,根据分析结果对吸头的结构进行优化设计。优化结果表明:各因素对吸头吸嘴口平均流速的影响重要性顺序由大到小依次为吸气管口径、真空度、内腔直径,当取吸气管口径8 mm、真空度80kPa、内腔直径为9mm时,吸嘴口流速的平均值最大,较改进前提高了约27%,样机试验结果表明优化后吸头使封套张开率达99.3%,提高电池包装效率的同时也为其它吸附装置的研究提供了参考依据。In order to solve the problem that the adsorption of the suction head to the envelope in the battery packaging machine is unstable and the packaging efficiency of the whole machine is affected,e.In this paper,the evaluation index of the performance of the suction head was obtained through the theoretical analysis of the envelope force.The flow field of different structural parameters was simulated by Fluent software and the results were analyzed.The structure of the suction head was optimized according to the analysis results.The optimization results showed that the importance of each factor on the average flow velocity of the nozzle mouth is from the largest to the smallest,the diameter of the suction pipe,the degree of vacuum,and the diameter of the cavity.When the diameter of the suction pipe is 8 mm,the vacuum is 80 kPa and the cavity diameter is 9 mm,the average value of the flow rate of the nozzle mouth is the largest,which is about 27%higher than that before the improvement.The prototype test results showed that the optimized nozzle has the opening rate of the envelope of 99.3%,which improves the packaging efficiency of the battery.The research of adsorption device provides a reference basis.
