除非另有定义，本申请所使用的所有的技术和科学术语与属于本申请的技术领域的技术人员通常理解的含义相同；本申请中在申请的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本申请；本申请的说明书和权利要求书及上述附图说明中的术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含。本申请的说明书和权利要求书或上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序或主次关系。
在本申请中提及“实施例”意味着结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本申请所描述的实施例可以与其它实施例相结合。
在本申请的描述中需要说明的是除非另有明确的规定和限定术语“安装”、“相连”、“连接”、“附接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
本申请中出现的“多个”指的是两个以上(包括两个)。
本申请中，电池单体可以包括锂离子二次电池、锂离子一次电池、锂硫电池、钠锂离子电池、钠离子电池或镁离子电池等，本申请实施例对此并不限定。电池单体可呈圆柱体、扁平体、长方体或其它形状等，本申请实施例对此也不限定。电池单体一般按封装的方式分成三种：圆柱电池 单体、方形电池单体和软包电池单体。
电池单体包括电极组件和电解液，电极组件由正极极片、负极极片和隔离膜组成。电池单体主要依靠金属离子在正极极片和负极极片之间移动来工作。正极极片包括正极集流体和正极活性物质层，正极活性物质层涂覆于正极集流体的表面，未涂敷正极活性物质层的正极集流体凸出于已涂覆正极活性物质层的正极集流体，未涂敷正极活性物质层的正极集流体作为正极极耳。以锂离子电池为例，正极集流体的材料可以为铝，正极活性物质可以为钴酸锂、磷酸铁锂、三元锂或锰酸锂等。负极极片包括负极集流体和负极活性物质层，负极活性物质层涂覆于负极集流体的表面，未涂敷负极活性物质层的负极集流体凸出于已涂覆负极活性物质层的负极集流体，未涂敷负极活性物质层的负极集流体作负极极耳。负极集流体的材料可以为铜，负极活性物质可以为碳或硅等。为了保证通过大电流而不发生熔断，正极极耳的数量为多个且层叠在一起，负极极耳的数量为多个且层叠在一起。隔离膜的材质可以为PP(polypropylene，聚丙烯)或PE(polyethylene，聚乙烯)等。此外，电极组件可以是卷绕式结构，也可以是叠片式结构，本申请实施例并不限于此。
相关技术中，切刀装置包括相对设置的一对切刀，一对切刀共同裁切极片。如果裁切质量不良，切刀与极片接触时引起极片的金属断面层沿着切刀运动的方向产生延展，形成拉丝缺陷。当极片与隔膜复合时，极片的拉丝可能会刺穿隔膜。当极片卷绕或者层叠形成电芯时，可能会导致不同极性的两层极片直接接触，导致电池单体内部发生短路。
发明人经研究发现，极片厚度、切刀的刀速与切刀间距具有相关性，在确定极片厚度、切刀的刀速的情况下，调节控制一对切刀沿极片走带方向的间距能够有效避免上述的拉丝缺陷。但是，目前大多数切刀装置的切刀间距调节精度不高，且在调节到位后容易松动，需要频繁调试，不仅难以调节控制切刀间距，且调节到位后切刀间距的稳定性较差。
基于上述思路，本申请提供一种新的技术方案，能够有效调节切刀间距，且调节到位后切刀间距稳定性较好，提高了切刀装置的裁切精度，提高了料带的裁切精度，进而提高了极片的裁切质量，提高了所成型的电池单体的安全性能。
图1示出的是本申请一些实施例中切刀装置的一种视角的结构示意图；图2示出的是图1中A处的局部放大图；图3示出的是图2中的B-B剖面图。
如图1、图2和图3所示，本申请的一些实施例提出一种切刀装置100。
切刀装置100包括第一切刀10和调节机构20，调节机构20用于调节第一切刀10的位置。调节机构20包括螺杆21和调节件22，调节件22套设于螺杆21且与螺杆21螺纹配合，调节件22与第一切刀10通过一对配合面楔形配合，螺杆21被配置为转动以驱动调节件22沿螺杆21的轴向移动，以使调节件22推动第一切刀10沿第一方向X移动，第一方向X垂直于螺杆21的轴向。
其中，料带为极片，极片用于成型电池单体的电芯。在其他实施例中，料带也可以为极片与隔膜覆合后形成的复合料带，也可以为其他形式的金属料带或者包括金属夹层的复合料带。料带的输送方向可以与第一方向X平行设置，第一切刀10的厚度方向与第一方向X平行设置，切刀装置100沿料带的宽度方向裁切料带；料带的输送方向也可以与第一方向X倾斜设置，第一切刀10的厚度方向与第一方向X倾斜设置，切刀装置100沿倾斜于料带的宽度方向裁切料带。
图4是本申请的一些实施例中调节机构的原理示意图。
如图3和图4所示，螺杆21包括螺杆本体211以及形成于螺杆本体211的一端的传动部212，传动部212用于供施加外力以驱动螺杆21绕自身轴线转动。传动部212可以为螺帽，以供人手动驱动转动；也可以与电机的输出端传动连接，实现自动化转动。
螺杆21的轴向沿第一轴线P延伸，第一方向X与第一轴线P相互垂直。切刀装置100还包括第二切刀40(请参照图1)，第二切刀40和第一切刀10沿第二方向Z相对设置，第二切刀40和第一切刀10能够沿第二方向Z相互靠近以共同裁切料带。
第一轴线P的延伸方向可以与第二方向Z平行设置，且利用第一切刀10的远离第二切刀40的一侧的空间布置螺杆21且暴露出螺杆21的传动部212，以便于驱动螺杆21转动。第一轴线P的延伸方向也可以沿其他方向延伸，例如，第一轴线P可以与第二方向Z、第一方向X均垂直。
如图4所示，调节件22具有第一配合面221，第一切刀10具有第二配合面112，调节件22与第一切刀10通过第一配合面221和第二配合面112楔形配合，调节件22沿第一轴线P移动时可以推动第一切刀10沿第一方向X移动。
具体而言，沿着调节件22沿第一轴线P的某一侧的移动方向，第一配合面221向靠近螺杆21中心轴线的方向倾斜，第二配合面112与第一配合面221平行设置。例如，当第一轴线P沿竖直方向延伸，调节件22竖直朝下移动以推动第一切刀10向远离螺杆21的一侧移动时，第一配合面221的下端比上端更靠近螺杆21的中心轴线；再例如，当第一轴线P沿竖直方向延伸，调节件22竖直朝上移动以推动第一切刀10向远离螺杆21的一侧移动时，第一配合面221的上端比下端更靠近螺杆21的中心轴线。
转动螺杆21以驱动调节件22沿螺杆21的轴向移动，调节件22与第一切刀10通过一对配合面楔形配合，从而推动第一切刀10沿第一方向X移动，能够调节切刀装置100的切刀间距，提高料带的裁切质量。且调节件22的移动方向与第一切刀10的移动方向相互垂直，能够使调节机构20结构紧凑，占据空间小，从而减小了切刀装置100的外形和体积大小。
如图4所示，在本申请的一些实施例中，螺杆21的轴向(即第一轴线P)与配合面之间的锐角夹角α小于第一方向X与配合面之间的锐角夹角β。
α＜β时，能够使调节件22沿第一轴线P的位移量大于第一切刀10沿第一方向X的位移量。基于同等螺距的螺杆21，调节第一切刀10相同的位移量需要螺杆21转动更多的圈数，从而提高了第一切刀10的位移精度，提高了切刀装置100的切刀间距的调节精度。例如，α＝5°，β＝85°；再例如，α＝40°，β＝50°等。
在其他实施例中，α与β也可以相等，或者α＞β，以实现更大的间距调节范围。
转动螺杆21时，调节件22发生的位移量大于第一切刀10的位移量，从而在同样的调节件22的位移量下使第一切刀10具有更小的位移量，能够提高第一切刀10的移动精度，进而提高切刀装置100的间距调节精度，提高料带的裁切质量。
如图3和图4所示，在本申请的一些实施例中，调节机构20还包括第一弹性件23，设置于螺杆21与调节件22之间，以沿螺杆21的轴向(即第一轴线P)张紧调节件22与螺杆21。
如图3和图4所示，调节机构20还包括固定连接的第一安装块24和第二安装块25，螺杆21安装于第二安装块25，调节件22被限制于第一安装块24。
如图3所示，其中，第一安装块24沿第一轴线P设有过孔241，调节件22不可转动地限制于过孔241内且沿第一轴线P能够在过孔241内发生位移。调节件22设有内螺纹孔，螺杆21沿第一轴线P贯穿内螺纹孔且与调节件22螺纹配合。
其中，第二安装块25与第一安装块24通过螺纹件固定连接，螺杆21绕第一轴线P可转动且沿第一轴线P不可发生位移地安装于第二安装块25。
第二安装块25设有沿第一轴线P延伸且一侧开放的槽口251,槽口251与过孔241对齐且共同构造成连通的内腔，螺杆本体211沿第一轴线P贯穿槽口251。螺杆21还包括环形凸台213，环形凸台213和传动部212分别沿第一轴线P从两侧与第二安装块25抵接，以将螺杆21绕第一轴线P转动安装于第二安装块25。通过该种结构形式，将第二安装块25夹持螺杆21的一端，以实现螺杆21相对于第一安装块24能够转动且不可沿第一轴线P发生位移，占用空间小，容许第一安装块24的远离第二安装块25的一侧具有足够的空间与第一切刀10连接。
在其他实施例中，调节机构20还可以包括两个端部轴承座，两个端部轴承座分别沿第一轴线P分别安装于第一安装块24的两端，从轴向两端转动支撑螺杆21，以简化螺杆21的构造。
第一弹性件23设置于槽口251与过孔241共同构成的连通的内腔，第一弹性件23的两端分别抵接于环形凸台213和调节件22，通过弹性力使调节件22的内螺纹与螺杆本体211的外螺纹紧密咬合。第一弹性件23可以设置有一个，一个第一弹性件23套设于螺杆本体211以占用较小的空间；第一弹性件23也可以设置有多个，多个第一弹性件23围绕螺杆本体211的周向间隔设置。 第一弹性件23为直弹簧，也可以为液压推杆或者气缸。
第一弹性件23沿螺杆21的轴向(即第一轴线P)张紧调节件22与螺杆21，能够避免调节件22与螺杆21相对松动而导致第一切刀10沿第一方向X晃动，引起切刀装置100的切刀间距改变，影响料带的裁切质量。
图5示出的是本申请一些实施例中第一切刀的结构示意图。
如图5所示，第一切刀10包括第一部分11、第二部分12和第一导向轴(图中没有示出)，第一部分11用于与调节件22楔形配合，第二部分12形成有第一切刀10的刀刃13，第一部分11和第二部分12分别连接于第一导向轴沿第一方向X的两侧。
具体而言，切刀装置100还包括第一支架30，第一切刀10沿第一方向X滑动安装于第一支架30，调节机构20安装于第一支架30。第一支架30和第一切刀10的长度方向均沿第三方向Y延伸，第三方向Y与第一方向X垂直设置。
请参照图3、图4和图5，在上述的“调节机构20还包括固定连接的第一安装块24和第二安装块25，螺杆21安装于第二安装块25，调节件22被限制于第一安装块24”的具体实施方式中，第一安装块24沿第一方向X的一端安装于第一支架30，另一端与第一部分11同侧设置。
如图5所示，在本申请的一些实施例中，第一部分11和第二部分12沿第一方向X分别设置于第一支架30的两侧，第一导向轴设置有多个，第一支架30设有多个沿第一方向X延伸的第一导向孔，第一导向轴与第一导向孔一一对应，第一导向轴贯穿对应的第一导向孔。该种结构形式既能够容许第一切刀10基于第一支架30沿第一方向X移动以调节切刀间距，又能够缩小第一切刀10与第一支架30总体上沿第一方向X的外尺寸，使得切刀装置100结构紧凑。
在其他实施例中，第一切刀10也可以沿第一方向X整体上位于第一支架30的一侧，以简化第一切刀10的构造。
第一部分11与调节机构20的调节件22通过一对配合面楔形配合，调节件22沿第一轴线P移动以推动第一部分11沿第一方向X的某一侧移动。

当第二切刀40为超声波切刀时，在裁切过程中产生振动以及裁切料带的过程中与料带摩擦，均会导致第二切刀40的温度升高，第二切刀40长时间维持高温状态会影响第二切刀40的结构强度，进而降低第二切刀40的使用寿命。
散热件81可以设置有多个，多个散热件81沿第三方向Y间隔设置；散热件81也可以设置有一个，且为沿第三方向Y延伸的长条形。

S3：使用切刀装置100裁切料带。
可以理解的是，料带可以沿水平方向输送，也可以沿竖直方向或者其他方向输送。在上述的“调节机构20包括两个螺杆21和两个调节件22”的实施方式中，转动两个螺杆21分别实现调节切刀间距变大或者变小。
结合料带的厚度和驱动组件50中驱动件51的转速分析得出适宜的切刀间距，使用调节机构20调节切刀间距，以避免裁切料带时切口处出现拉丝缺陷。
使用本申请实施例中的裁切方法进行裁切料带，能够转动螺杆21以推动第一切刀10沿料带的走带方向移动，以调节切刀装置100的切刀间距，进而提高料带的裁切质量。

在使用切刀装置100裁切料带之前需要对切刀装置100的切刀间距进行调试，具体调试过程如下：
将第二切刀40固定于第二支架60；
拧动螺杆21，螺杆21转动并带动调节件22下降，调节件22与第一切刀10的第一部分11 楔形配合，调节件22下降时通过一对配合面推动第一切刀10沿第一方向X移动，以使切刀间距变小，第一弹性件23抵接于螺杆21与调节件22之间起到防松作用；或者拧动另一个螺杆21，使另一个螺杆21对应的调节件22下降，以使切刀间距变大。检测第二切刀40与第一切刀10沿第一方向X的间距，当第二切刀40与第一切刀10沿第一方向X的间距符合要求时，切刀装置100调试完毕，经过调试的切刀装置100在裁切料带作业过程中能够有效避免料带的切口产生拉丝缺陷。
使用切刀装置100裁切料带的过程如下：
极片沿输送路径行进，经过导向件82引导进入第一切刀10和第二切刀40之间的缝隙，第二切刀40在超声波发生器作用下振动，驱动件51驱动偏心轮转动，以通过连杆带动第一切刀10下降，压持件71下降以将料带压在第二切刀40的上表面，第一切刀10继续下降，刀刃13配合第二切到40的高频率振动共同裁切料带，第二切刀40表面贴有半导体冷却片以降低第二切刀40的温度。
在裁切料带的过程中，第一切刀10通过电机结合凸轮连杆组件的形式来实现往复运动，第一切刀10能够在运动至下限位后立即垂直向上进行回程运动，能够实现高频率往复运动，进而实现高频率裁切作业。通过压持件71的吸尘口711负压吸附粉尘，通过导向套筒组件90上安装的磁性件93利用磁性吸附金属粉尘，能够从切刀装置100的内部以及外部均进行粉尘清理，整体维持加工环境清洁。
