摘 要:鋰離子電池的極柱結構有平面型和螺紋型,螺紋型結構極柱面積較小,充放電設備的輸出端無法完全接觸到電池極柱,因此需要引入轉接頭擴充電池極柱面積,保證設備和電池接觸良好。轉接頭使用頻率高,容易被污染,需要頻繁清洗。由于數量眾多,轉接頭的螺紋結構不易徹底清洗,所以手工清洗效率低、效果差。超聲波清洗轉接頭效率高,清洗徹底,可大量推廣。本文介紹超聲波清洗轉接頭的原理、參數選擇,并給出結構設計及清洗效果。

Abstract: Column structure of lithium-ion batteries has a thread model and plane model. Because the thread type of column area is lesser, the output of the charing and discharging equipment cannot access to the battery polo column. Connector is needed to extend battery pole column area, to ensure good contact. Connector is used in lithium-ion batteries in charing and discharging process. Because the connector use frequency is high, easy to be polluted, so we need to frequent cleaning. Manual cleaning efficiency is low and the effcct is poor, because of numerous and thread structure not to wash easily. Ultrasonic cleaning can be promoted a large number, because of high efficiency and clean thoroughly. In this paper, the principle, parameter selection, structure design and cleaning effect of ultrasonic cleaning adapter were introduced.

鋰離子電池出廠前,要進行內部電能激活,采用專用的化成設備對單個電池反復充放電。目前多數化成設備的充放電方式是:化成設備的輸出端壓在電池極柱上,形成電流回路,完成電池的充放電。電池極柱結構不同,有螺紋型和平面型,螺紋型的電池極柱面積小于充放電設備的輸出端,充放電設備的輸出端無法完全接觸到電池極柱,需要引入轉接頭作為中介,擴充電池極柱面積,保證充放電設備和電池接觸良好。由于使用頻率高、頻繁接觸指紋,使用環境中接觸電解液,因此轉接頭極易被污染,需要頻繁清洗。
常規的水浸泡無法溶解轉接頭表面的電解液和油漬,超聲波作為近幾年的一個新興技術,在工業清洗中的應用日趨成熟,采用超聲波清洗轉接頭能夠有效、高速地去除轉接頭表面的污漬[1]?!?br>
