以使用极片料轮820在工作,备用极片料轮821为为例。当使用极片料轮820上的料卷快用完时,压力传感器930向控制器报警,压带机构压住当前使用极片不让它动。这时,手动将备用极片料轮821上的备用极片穿过自动接带装置1的该第一接带吸盘729与第二接带吸盘769之间再与废料收集轴941连接。启动自动接带装置1,该第一接带吸盘729与第二接带吸盘769等高对贴吸住该使用极片料带与备用极片料带两条极片料带。
切极片刀732在切刀气缸734的作用下从第一接带吸盘729或者第二接带吸盘769中间伸出切断两个极片料带,然后废料收集轴941和放卷轴822在放卷电机901和废料收集轮电机驱动下转动,带动两个余料极片料带脱离两个接带吸盘,第一接带吸盘729和第二接带吸盘769。清除余料后,第一接带吸盘729和第二接带吸盘769所吸取的极片料为使用极片料带剩余部分和备用极片料带的初始部分。然后控制器驱动左侧备胶机构备胶,由第一贴胶机构贴胶从左侧对该使用极片料带与备用极片料带的切断接口处贴胶;然后控制器驱动右侧备胶机构备胶,由第二贴胶机构贴胶从右侧对该使用极片料带与备用极片料带的切断接口处贴胶。
左右备胶机构上的第一胶带和第二胶带通过进给机构开始备胶,比如第一进给机构的备胶轮、过胶牙轮213、过胶光轮214以及过胶光轮215。穿过夹胶机构,比如穿过第二夹胶机构中的夹胶固定块116和夹胶转动块117。通过夹胶机构夹稳胶带,比如,该第一夹胶机构的第一夹胶气缸239作用下使得夹胶转动块117与夹胶固定块116并拢而夹紧胶带,在第一拉胶气缸237的推动使得第一贴胶移动板409向前移动,然后贴胶吸盘430向前移动贴近和吸附胶带。然后,就是第一压胶气缸349启动带动第一压胶块346转动将从夹胶机构中伸出的胶带压在第一贴胶吸盘430上,胶带被第一贴胶吸盘430和第一压胶块346压紧后,夹胶机构松开夹紧的胶带,然后该第一贴胶移动板409退回原来位置,夹胶机构又夹紧胶带。两头被夹紧的胶带被切胶机构切断,比如,被第一切胶机构的切胶刀106切断。切断的胶段被贴胶吸盘吸住,比如被第一贴胶吸盘430吸住,吸住胶片的第一贴胶吸盘430向上移动与第二接带吸盘769对贴,从而将两极片料带的切断接口处一侧用胶段粘贴连接。同理,第二贴胶吸盘向上移动与第一接带吸盘729对贴,在另一侧贴住两极片料带切断接口处,实现两侧粘贴连接。最后,剩余的使用极片料带牵引新接带的备用极片料带继续工作,从而实现自动换带换卷。反之亦然。
本实施例的用于电芯卷绕的自动换带装置,通过备胶机构裁切所需长度的胶带,再通过该第一贴胶机构和第二贴胶结构全自动对该使用极片料带与备用极片料带的切断接口处完成双面贴胶,提供接带效果更好的全自动换带装置,以实现自动换带,使用极片料带快用完时,备用极片料带在自动换带装置上与该使用极片料带连接,无须停机继续工作。同时,本实施例的用于电芯卷绕的自动换带装置设置废料收集轴,可及时清除多余余料。本实施例的用于电芯卷绕的自动换带装置还设置极片纠偏装置,保证在极片接带的过程中极片能够准确对齐,提高设备卷绕电芯的良品率。
以上所述仅为本申请的实施方式,并非因此限制本申请的专利范围,凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换,或直接或间接运用在其他相关的技术领域,均同理包括在本申请的专利保护范围内。
