电池的极耳部是从电芯中将正负极引出壳体的金属导电体,因此在电池的装配过程中,电池的极耳部需要引出壳体外部,以作为电池进行充放电时的接触点。但是在电池的装配过程中,电池的电芯在装配壳体时,极耳部容易弯折在壳体内部而无法延伸出壳体外,电芯和壳体之间难以顺利完成装配,因此导致电池的装配制备工艺的难度较高,且电池的制备良品率较低。
为了实现电极组件的精准入壳,顺利将极耳部从壳体内延伸出壳体外,可以在电极组件入壳时对极耳部进行引导,使得极耳部顺利从壳体内延伸出壳体外。
基于以上考虑,本申请提供电池的穿极耳装置、组装设备和装配方法。电池包括壳体和电极组件;壳体具有容纳腔,壳体上开设有连通容纳腔和外界的通孔,电极组件设置于容纳腔,穿极耳装置用于引导电极组件的极耳部从通孔伸出。穿极耳装置包括导向件和支撑机构,导向件用于穿入通孔,支撑机构与导向件连接,用于固定导向件的第一端。其中,导向件用于伸入容纳腔,并引导极耳部经过通孔伸出容纳腔。如此,在不对壳体造成影响和损坏的前提下,能够引导极耳部顺利穿入通孔内,使得极耳部能够顺利延伸出壳体,从而使得极耳部不易阻挡壳体套入电极组件,极耳部也不易与壳体发生磕碰而造成损坏或无法顺利穿入通孔,进而实现电极组件的精准入壳,有效提高穿极耳装置的工作稳定性和可靠性,有效降低电池的装配难度,有效提升电池的装配效率和良品率。
