Description

切割机构及入料装置 技术领域
本申请涉及电池制造设备技术领域，特别是涉及一种切割机构及入料装置。
背景技术
在电池生产制造过程中，需要使用切割机构对极片进行切割。切割机构包括刀座、定刀及动刀组件，定刀固设于刀座上，动刀组件包括导杆及导杆架，导杆与刀座滑动连接，动刀与导杆架分别与导杆的两端连接。切割机构还包括驱动组件，驱动组件与导杆架连接。工作时，驱动组件驱动导杆架带动导杆运动，以使动刀向定刀运动，动刀与定刀相配合以对极片进行切割。
一般地，驱动组件与导杆架的一端相连，造成驱动组件施加于导杆架上的施力点在导杆架的一端，这样导致靠近施力点一端的导杆的受力较大，磨损严重，进而造成各处导杆的磨损程度不同。正是各处导杆的磨损程度不同，造成导向倾斜，使得动刀与定刀之间产生间隙，导致切割效果不佳，如易于产生切割毛刺。

参阅图1，本申请一实施例提供一种入料装置100，用于被切割件200的入料以及切割被切割件200。具体地，被切割件200为用于制造电池的极片。应当理解的是，在另一些实施例中，对于被切割件200的种类不作限定。
下面以入料装置100用于极片的入料及切割为例，对本申请做详细说明，但是该说明并不会限制本申请的保护范围。
入料装置100包括安装座10及切割机构20，切割机构20安装于安装座10上。具体地，参阅图1及图2，切割机构20包括刀座21、定刀22、动刀组件23及驱动组件28。刀座21安装于安装座10上，定刀22固设于刀座21上。参阅图3，动刀组件23包括安装件231及动刀232，安装件231沿第一方向滑动设于刀座21上，动刀232安装于安装件231上。参阅图1及图4，入料装置100 还包括导向机构50，驱动组件28包括第一端和第二端，第一端与导向机构50配合设置，第二端与安装件231连接。
进一步，刀座21与安装座10沿第二方向滑动连接，第一方向与第二方向相交。具体地，安装座10上设有沿第二方向延伸的第二滑轨30，刀座21上设有第二滑块，第二滑块与第二滑轨30滑动连接。刀座21通过第二滑块与第二滑轨30配合以与安装座10沿第二方向滑动连接，使得刀座21的移动更加顺畅。在刀座21带动位于其上的部件相对于安装座10沿第二方向运动的过程中，导向机构50能够驱使驱动组件28沿第一方向施加驱动力于安装件231，以使安装件231带动动刀232靠近定刀22运动以在预设位置切割被切割件200。
入料装置100在工作时，极片进入定刀22与动刀232之间。控制刀座21带动位于其上的部件相对于安装座10沿第二方向运动，运动速度与极片的传送速度相等，在刀座21相对于安装座10沿第二方向运动的过程中，导向机构50能够驱使驱动组件28沿第一方向施加驱动力于安装件231，安装件231带动动刀232靠近定刀22运动，最终在预设位置动刀232与定刀22配合以将极片切断。这样，刀座21带动位于其上的部件沿第二方向相对于安装座10运动的过程中，驱动组件28能够施加驱动力于安装件231，安装件231带动动刀232靠近定刀22运动以在预设位置与定刀22配合将极片切断，实现了飞切的效果，以便于快速切割极片，减少切割时间，提高了生产效率。
在此需要说明的是，在预设位置切割极片的意思是：在刀座21相对于安装座10沿第二方向运动的过程中，并非在任何位置驱动组件28都会向安装件231施加驱动力，而是当刀座21相对于安装座10运动至一定位置时，驱动组件28才能沿第一方向施加驱动力于安装件231。而当驱动组件28沿第一方向向安装件231施加驱动力时，动刀232才能向定刀22运动，并最终与定刀22配合以 在预设位置切割极片。
第二方向与极片的传送方向(即为极片的长度方向)平行。具体地，第二方向与第一方向垂直。第一方向为与极片所在平面相垂直的方向，也即为，第一方向为极片的厚度方向。
进一步，定刀22及动刀232均沿平行于第三方向的方向延伸，第一方向、第二方向及第三方向两两垂直。此时，第三方向为极片的宽度方向。设置定刀22及动刀232沿第三方向延伸的长度大于极片的宽度，以便于将极片切断。
参阅图1，第一方向为图1中的X方向，第二方向为图1中的Z方向。参阅图3，第三方向为图3中的Y方向，也为图1所示的垂直纸面的方向。
参阅图5，入料装置100还包括第一驱动件40，刀座21与第一驱动件40的第一驱动端连接，第一驱动件40能够驱动刀座21带动其上的部件沿第二方向运动。具体地，第一驱动件40为电机，电机通过丝杆模组和刀座21连接。当然，在另一些实施例中，对于第一驱动件40的种类不作限定，如第一驱动件40还可以为气缸等。
一实施例中，参阅图2，切割机构20还设有第二弹性件24，第二弹性件24夹设于刀座21与定刀22之间。通过设置第二弹性件24，以便于调节定刀22与动刀232之间的间隙。
一实施例中，参阅图3，安装件231具有一与第一方向平行的中心线L，驱动组件28的第二端与安装件231对应中心线L的部位相连。而正是由于驱动组件28与安装件231对应中心线L的部位相连，使得驱动组件28施加于安装件231上的施力点位于安装件231的中心线L上，这样，使得安装件231位于中心线L两侧的部分受力均衡，相对于现有技术中驱动组件28的施力点靠近安装件231一端的情况，避免安装件231与刀座21连接部位中靠近施力点的一端磨损 程度较大而造成动刀232与定刀22之间产生切割间隙的情况发生，切割效果较好。
在此需要说明的是，中心线L为安装件231所在平面的中心线。驱动组件28的第二端与安装件231对应中心线L的部位相连的意思是：在中心线L的延伸方向上，驱动组件28能够与安装件231对应中心线L的位置相连，保证驱动组件28施加于安装件231上的施力点位于安装件231的中心线L上，以保证安装件231位于中心线L两侧的部分受力均衡。
参阅图3，安装件231包括导向件2311及连接件2312，导向件2311沿第一方向滑动设于刀座21上。沿第一方向，动刀232及连接件2312分别连设于导向件2311的两端，驱动组件28的第二端与连接件2312连接。驱动组件28的第二端与连接件2312对应中心线L的部位连接。参阅图3，驱动组件28的第二端与连接件2312沿第三方向的中间部位连接。驱动组件28驱动连接件2312运动时，通过导向件2311带动动刀232沿第一方向运动。
由于驱动组件28的第二端与连接件2312的沿第三方向的中间部位相连，则驱动组件28施加于连接件2312的施力点在连接件2312的中间部位。这样，使得导向件2311沿第三方向的左右两侧受力均衡，避免一侧导向件2311磨损程度较多而造成的动刀232与定刀22之间产生切割间隙的情况发生，切割效果较好。
导向件2311包括至少两组导杆组，每组导杆组包括至少一根导杆23111，每根导杆23111的延伸方向与第一方向平行。两组导杆组对称设于中心线L的两侧，每根导杆23111的两端分别与动刀232及连接件2312相连。通过设置导向件2311包括两组导杆组，使得导向件2311与刀座21的滑动更加顺畅。
一个具体实施方式中，每组导杆组包括一根导杆23111，驱动组件28的第 二端与连接件2312在第三方向的中间部位连接。这样，使得两根导杆23111的受力均衡，以避免一侧导杆23111磨损较严重的情况发生。
具体地，参阅图6，刀座21内设有导向套25，每根导杆23111套接于相对应的导向套25内，以减小导杆23111与刀座21之间的摩擦力，减少磨损。切割机构20还包括第一弹性件26，第一弹性件26设于导向套25与连接件2312之间，为动刀组件23提供缓冲。
优选地，连接件2312也为杆状结构，以进一步减轻安装件231的重量，便于安装件231相对于刀座21滑动。
可以理解的是，在另一些实施例中，对于安装件231的具体设置不作限定，只要能够实现与驱动组件28连接，且能够在驱动组件28的驱动作用下带动安装于其上的动刀232相对于刀座21运动的效果即可。
一实施例中，参阅图6，安装件231还包括安装板2313，安装板2313与导杆23111连接，动刀232安装于安装板2313上。如此，便于动刀232的安装。
进一步，切割机构20还包括压紧件27，压紧件27沿第一方向活动设于安装板2313上，以在动刀232与定刀22配合切割极片之前，将极片压紧于定刀22上，方便极片的切割。
继续参阅图4，驱动组件28包括驱动板282、配合件281及连接块283。配合件281与驱动板282相连，并与导向机构50配合设置，连接块283连接于驱动板282与安装件231。如此设置，简化了驱动组件28的结构。具体地，配合件281为设于驱动板282端部的滚轮，滚轮设于导向机构50的导向槽51(下述)内。
一个具体实施方式中，驱动板282为L型结构，滚轮与L型结构的短边2821相连，连接块283与L型结构的长边2822外侧相连。这样，驱动板282不会妨 碍滚轮与导向槽51配合，且便于与连接件2312连接。当然，在其他一些实施例中，对于驱动板282的具体形状不作限定。
进一步，驱动板282与刀座21中一者上设有与第一方向平行的第一滑轨60，另一者上设有第一滑块70，第一滑块70与第一滑轨60滑动连接，驱动板282与刀座21通过第一滑块70与第一滑轨60配合实现沿第一方向的滑动连接。具体地，第一滑轨60具有两个，沿第三方向，两个第一滑轨60分布于连接块283的两侧。第一滑块70也为与第一滑轨60相配合的两组。如此，能够提高整个结构的运行稳定性。
一个实施例中，继续参阅图4，连接块283包括第一连接部2831及第二连接部2832，第一连接部2831与安装件231及驱动板282中一者相连，第二连接部2832与安装板2313及驱动板282中另一者相连。第一连接部2831内开设有配合孔，第二连接部2832沿与第二方向平行的方向延伸，第二连接部2832穿设于配合孔内。
具体地，第二连接部2832与安装件231连接，第一连接部2831与驱动板282连接。应当理解的是，在另一些实施例中，第二连接部2832也可以与驱动板282连接，此时，第一连接部2831与安装件231连接。
上述设置，通过第二连接部2832与配合孔的配合方便驱动组件28与安装件231的连接，同时，便于消除驱动组件28与安装件231沿第二方向(第二连接部2832的轴向)的安装误差。
第一连接部2831的配合孔为腰形孔，腰形孔沿平行于第三方向的方向(定刀22及动刀232的延伸方向)纵长延伸，使得第二连接部2832在第三方向上与配合孔之间具有活动间隙，便于消除驱动组件28与安装件231沿第三方向的安装误差。
一个具体实施方式中，继续参阅图6，第二连接部2832包括本体2833及套接于本体2833外的套筒2834，本体2833与套筒2834均穿设于配合孔内。这样设置，使得驱动组件28与安装件231相对运动时摩擦力较小，减小磨损。
一实施例中，参阅图7，导向机构50面向驱动组件28的一侧设有导向槽51，导向槽51具有依次连通的第一直槽段511、弧形槽段512及第二直槽段513，第一直槽段511及第二直槽段513均沿第二方向延伸，弧形槽段512沿第一方向向定刀22的一侧弯曲。这样，当刀座21带动安装于其上的部件相对于安装座10沿第二方向运动时，滚轮在导向槽51内沿导向槽51的轨迹运动，而当滚轮运动至弧形槽段512时，在弧形槽段512的作用下，驱动组件28带动安装件231沿第一方向运动，以使得安装件231带动动刀232靠近定刀22运动，并与定刀22在预设位置切割极片，以实现飞切。
当然，在另一些实施例中，对于导向机构50的具体设置方式不作限定，只要能够实现在第二方向导向驱动组件28，且能够促使驱动组件28施加驱动力于安装件231，以使安装件231在第一方向带动动刀232运动的设置方式均可。
入料装置100还包括第二驱动件，导向机构50与第二驱动件的第二驱动端连接。第二驱动件通过驱动导向机构50远离或靠近滚轮运动，调整导向机构50与滚轮之间的距离，进而控制导向机构50的导向槽51与滚轮之间的距离，也即为控制导向机构50对驱动组件28的限制。具体地，当滚轮完全脱离导向机构50的导向槽51时，解除导向机构50对驱动组件28的限制，也即为解除导向机构50对动刀组件23的限制；当滚轮与导向机构50的导向槽51配合时，通过导向机构50对动刀组件23的运动轨迹进行限制。
一实施例中，继续参阅图1，入料装置100还包括夹持机构80，夹持机构80沿第二方向与安装座10滑动连接，并与切割机构20沿第二方向依次布设。 沿第二方向，夹持机构80能够与切割机构20相对于安装座10同步滑动，具体地，夹持机构80的移动的速度与极片的传送速度相等，以在切割机构20切割极片前，将极片夹紧。这样设置，刀座21带动其上的部件沿第二方向运动时，夹持机构80能够同步运动，而动刀232与定刀22在预设位置切割极片前，夹持机构80能够将极片夹紧，以防止切割机构20切割极片时发生偏移，以提高切割精度。
参阅图8及图9，夹持机构80包括夹持座81、固定夹持辊82和活动夹持辊83。夹持座81与安装座10沿第二方向滑动连接，固定夹持辊82固设于夹持座81上，活动夹持辊83与夹持座81活动连接，以与固定夹持辊82配合夹紧极片。夹持机构80还包括设于夹持座81上的第三驱动件84，活动夹持辊83与第三驱动件84的第三驱动端连接，第三驱动件84受控驱动活动夹持辊83靠近或远离固定夹持辊82运动。具体地，第三驱动件84为驱动气缸。在另一些实施例中，对于第三驱动件84不作具体限定，只要能够实现驱动活动夹持辊83运动的目的即可。
另一些实施例中，对于夹持机构80的具体结构不作限定，只要能够达到夹紧极片的目的即可。
进一步，安装座10上设有第三滑轨，夹持座81上设有第三滑块，第三滑块与第三滑轨滑动连接。夹持座81通过第三滑块与第三滑轨配合以与安装座10沿第二方向滑动连接。更进一步，第一滑轨60与第三滑轨为同一滑轨，以使得结构更为紧凑，减小入料装置100的体积。
一实施例中，继续参阅图5，入料装置100还包括第四驱动件90，夹持座81与第四驱动件90的第四驱动端连接，第四驱动件90受控驱动夹持座81带动其上的部件沿第二方向运动。具体地，第四驱动件90为电机。当然，在另一些 实施例中，对于第四驱动件90的种类不作限定，如第四驱动件90还可以为气缸等。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
