技术领域
本实用新型涉及电池叠片设备,具体是涉及一种动力电池电芯的全自 动制极片袋设备。 背景技术
现有采用先制极片袋后叠制极片方式制作大型锂离子动力电池电芯 时,有一种制袋方法是:在将预先裁好的极片用两层隔膜包裹后,采用热 焊方式焊接先进行单缝竖向热焊一次,再进行第二次横向热焊接封合成袋, 且将极片极耳露在袋外。这种制袋方法的缺陷是不能保证两个相邻竖焊缝 之间的距离,难以采用切刀切断下料,且热焊刀温度控制的高低对焊接口 有很大的影响,尤其是焊接时间过短,隔膜难以焊上,焊接时间过长,又 会损坏隔膜。 发明内容:

本实用新型具体实施方式的工作过程如下:
(一) 极片取料
如图5、 6所示,极片上料组件6的转盘603上设有三个装载有预先裁 好的极片的储料盒602,左伺服驱动电机606驱动顶料座605,带动顶块控 制储料盒602中极片的高度,实现极片的吸附动作。吸附极片由两个真空 吸盘703、 705动作完成,当顶杆把极片顶到传感器感应到的位置,由右真 空吸盘703开始从储料盒602中吸取极片到极片送料整形组件7上。送料 伺服驱动电机701开始带动右真空吸盘703去吸取下一极片,为保证极片 按设定位置稳定地进入下一工序,由左定位固定块707和下定位固定块709 对前一极片相邻两边定位,整形过程中由两整形组件汽缸710带动定位块 711将极片的两边进行整形,定位整形后由左真空吸盘705将极片送至隔 膜3上,重复上述动作完成极片取料过程。
(二) 制袋焊接
如图3、 4所示,先进行竖向热焊,固定在竖向热焊接组件4上模固定 板402上的双刀刃压焊切刀403,刀刃相距2mm,由上模汽缸408带动上 下移动。竖向热焊接下模上垫设有硅胶,由下模汽缸405带动上下移动, 竖向热焊接上模、竖向热焊接下模通过固定板固定于基板上,当PLC控制 竖向热焊接组件4动作时,竖向热焊接上模、竖向热焊接下模同时动作, 双刀刃压焊切刀403竖向热焊接极片袋的两侧袋边。
竖向热焊接完成后,隔膜3由隔膜夹持牵拉组件7驱动到达程序控制 设定位置进行第二道横向热焊。横向热焊接组件5的动作原理与竖向热焊 接组件4类似,但热焊刀504是安装在横向热焊接组件下模上,分别位于 两端,下模上的压头下板503起缓冲作用,橫向热焊接上模上垫设有硅胶。焊接时横向热焊接上模、横向热焊接下模同时动作,长热焊刀横向热焊接 极片袋的袋底,短热焊刀横向热焊接极片袋的袋口,将极片极耳露在袋外。 直到按参数设定完成动作后返回原位,极片袋的焊接过程结束。 (三)隔膜驱动与成品焊片切断下料
如图7〜10所示,隔膜夹持牵拉组件8的左、右两侧机械夹手805的 固定端安装在夹持汽缸804上,夹持汽缸804固定在固定块803上,再通 过滑块定位连接在同步带上。右侧机械夹手夹紧隔膜3时,左侧机械夹手 处于张开状态,动作时,右侧机械夹手牵扯隔膜3通过左侧机械夹手中间 缝隙向左移动,同时相对应的左侧机械夹手向右移动,当左、右两侧机械 夹手805互换位置时,左侧机械夹手闭合夹紧隔膜3,隔膜切断组件9的 热切刀901向上动作,切断隔膜3,由下料输送组件10的下料伺服驱动电 机1004带动输送皮带1001完成成品下料动作,动作完成后,右侧机械夹 手张开,然后上述动作重复进行。在隔膜3移动过程中,通过PLC程序控 制隔膜放料张力组件11的放料电机的运转速度,保证隔膜3张力基本恒定。
本实用新型在各部分动作中,通过PLC程序控制,通过传感器进行检 测定位,如各汽缸到位与否的判断,热焊切刀和热切刀的动作时间,隔膜 夹持牵拉组件动作行程,极片吸盘是否吸取到极片都由PLC和传感器控制 反馈执行,以及热焊切刀和热切刀的温度由温度控制装置进行精确的控制。
以上内容是结合具体的优选实施方式对本实用新型所作的进一步详细 说明,不能认定本实用新型的具体实施只局限于这些说明。对于本发明所 属技术领域的普通技术人员来说,在不脱离本实用新型构思的前提下做出 若干等同替代或明显变型,而且性能或用途相同,则应当视为属于本实用 新型由所提交的权利要求书确定的保护范围。
