Description

一种换型方法以及电池托盘
本申请要求于2022年09月28日提交中国专利局、申请号为202211196813.3、申请名称为“一种换型方法以及电池托盘”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电池生产设备技术领域，特别涉及一种换型方法以及电池托盘。
背景技术
在电池的生产过程中，如拔钉、化成、分容等众多工序中，往往采用托盘转运电池以及将电池装载在托盘内进行加工。然而，电池的型号众多，各型号的电池尺寸也会有差异，为了能够兼容多种不同尺寸的电池，现阶段通常是通过设置不同尺寸的分隔板对电池进行夹持，分隔板旨在对不同宽度的电池进行兼容，并利用分隔板对电池夹紧，从而兼容不同宽度的电池。然而，如果分隔板对电池的夹持力过大，容易损坏电池，如果夹持力过小，又容易因夹持不稳而导致电池偏移。
如果再设计多种不同尺寸的分隔板来对电池的长度进行限位，不仅大大增加了成本，而且还需要在厂房腾出空间设置存放区来存放分隔板。
再者，若想使用机械臂来更换用于对电池的长度限位的分隔板，则还需要再设置一个分隔板更换区，即人工将所需分隔板从分隔板存放区筛选出来，并将其调度至该分隔板更换区后，再通过机械臂来夹持，操作复杂；然而即使如此，由于分隔板尺寸不同，机械手对分隔板进行夹持和安装也是极大的考验。

如图1所示，本申请中所描述的容置腔的长度方向为L、宽度方向为W、高度方向为H，第一容置腔400/第二容置腔500的中心面如图中虚线所示平面。
参照图1至图5，本申请公开了一种换型方法，包括通过一对限位组件300对被限位件进行限位，限位组件300设有第一限位面330和第二限位面340；一对限位组件300的两个第一限位面330相向设置并形成第一容置腔400，第一容置腔400的长度为L1；调整一对限位组件300的状态，以使两个第二限位面340相向设置并形成第二容置腔500，第二容置腔500的长度为L2，L1不等于L2。
可以理解的是，一对限位组件300应该包括偶数个限位组件300，如2个、4个等。一对限位组件300的状态包括仅调换一对限位组件300中的每个限位组件300的位置，或者是仅改变一对限位组件300 中的每个限位组件300的朝向，以实现通过一对限位组件300对不同尺寸的被限位件的两端进行限位。应当理解的是，为了使被限位件的受力更加均衡，一对限位组件300呈轴对称设置，即一对限位组件300关于第一容置腔400/第二容置腔500的中心面对称设置，该中心面沿第一容置腔400/第二容置腔500的高度方向延伸。
此外，第一容置腔400和第二容置腔500是相对的，本申请对此处描述的第一容置腔400和第二容置腔500不作限制，只要第一容置腔400的长度L1和第二容置腔500的长度L2不相等即可，也就是说，当L1大于L2时，利用本申请的换型方法可以将兼容大尺寸的被限位件的第一容置腔400切换为兼容小尺寸的被限位件的第二容置腔500；同理，当L1小于L2时，利用本申请的换型方法可以将兼容小尺寸的被限位件的第一容置腔400切换为兼容大尺寸的被限位件的第二容置腔500。
通过一对限位组件300的状态即可形成不同尺寸的容置腔，从而兼容不同尺寸的被限位件，方法简单，可方便快捷地对被限位件进行限位。进一步说，由于需要调整的是同一对限位组件300，即限位组件300的结构和尺寸不变，有利于调节机械臂的夹持力以及机械臂调度限位组件300时的行程，进而有助于利用机械臂实现自动化换型以适应不同尺寸的被限位件。限位组件300为型材。
第一限位面330和第二限位面340为同一限位组件300的相互背离的两个端面。一种状态下，一个限位组件300的第一限位面330与另一个限位组件300的第一限位面330相向，两个第一限位面330之间的区域为第一容置腔400，两个第一限位面330形成第一容置腔400在长度方向上的两个侧壁。另一种状态下，一个限位组件300的第二限位面340与另一个限位组件300的第二限位面340相向，两个第二限位面340之间的区域为第二容置腔500，两个第二限位面340形成第二容置腔500在长度方向上的两个侧壁。
参见图2和图3，一对限位组件300所处区域分别为第一位置和第二位置，调整一对限位组件300的状态包括：将第一位置的限位组件300移动至第二位置，将第二位置的限位组件300移动至第一位置，以使一对限位组件300的两个第二限位面340相向设置并形成第二容置腔500。一对限位组件300进行位置互换即可实现第一容置腔400与第二容置腔500的切换，进而实现对不同尺寸的被限位件的限位。
可以想象的是，将第一位置的限位组件300移动至第二位置，将第二位置的限位组件300移动至第一位置这一步骤可以是通过两个机械臂分别同时抓取位于第一位置和第二位置的限位组件300，并进行位置互换后，再同时将位置互换后的限位组件300放入第一位置和第二位置。
将第一位置的限位组件300移动至第二位置，将第二位置的限位组件300移动至第一位置这一步骤还可以是，将第二位置的限位组件300移动至第三位置，第三位置为第一容置腔400/第二容置腔500的外侧区域，然后将第一位置的限位组件300移动至第二位置，接着将第三位置的限位组件300移动至第一位置，以使一对限位组件300的两个第二限位面340相向设置并形成第二容置腔500。第三位置作为中转位置，设于第一容置腔400/第二容置腔500的外侧区域，不会对调度作业造成障碍。如此设置，可通过一个机械臂实现第一位置的限位组件300和第二位置的限位组件300的位置互换，操作简单。优选地，第三位置与第一位置、第二位置两两平行，在机械臂抓取限位组件后，仅需要平移即可完成互换， 路径简单，有利于提高准确率。
需要说明的是，第一位置和第二位置是相对的，本申请对此处描述的第一位置和第二位置不作限制，也就是说如图2所示的实施例中，若第一位置位于沿第一容置腔400/第二容置腔500的长度方向的一端，则第二位置位于沿第一容置腔400/第二容置腔500的长度方向的另一端，反之亦然。
参见图4和图5，一对限位组件300均具有第一轴，第一轴沿第一容置腔400的高度方向延伸，调整一对限位组件300的状态进一步包括：一对限位组件300以第一轴为旋转轴旋转180°，以使一对限位组件300的两个第二限位面340相向设置并形成第二容置腔500。
可以理解的是，一对限位组件300中的每一个限位组件300均具有第一轴，采用每个限位组件300绕自身的第一轴自转的方式，无需互换一对限位组件300的位置即可是实现第一容置腔400与第二容置腔500之间的切换。
参见图2和图3，一对限位组件300均具有第二轴，第二轴沿第一容置腔400的宽度方向延伸，调整一对限位组件300的状态进一步包括：一对限位组件300分别绕自身的第二轴旋转180°，以使一对限位组件300的两个第二限位面340相向设置并形成第二容置腔500。
可以理解的是，一对限位组件300中的每一个限位组件300均具有第二轴，采用限位组件300绕自身第二轴自转的方式，无需互换一对限位组件300的位置即可实现第一容置腔400与第二容置腔500之间的切换。
可以想象的是，第一限位面330与第二限位面340形成M度的夹角，或者第一限位面330的延长线与第二限位面340的延长线形成M度的夹角，一对限位组件300均具有第三轴，第三轴沿第一容置腔400的高度方向延伸，调整一对限位组件300的状态进一步包括：一个限位组件300以自身的第三轴正向旋转N度，另一个限位组件300以自身的第三轴反向旋转N度，其中，N＝180°-M，0°＜M＜180°，以使一对限位组件300的两个第二限位面340相向设置并形成第二容置腔500。
以M＝90°为例，参见图6、图7、图10和图11，第一限位面330与第二限位面340相互垂直，一对限位组件300均具有第三轴，第三轴沿第一容置腔400的高度方向延伸。调整一对限位组件300的状态进一步包括：一个限位组件300以自身的第三轴正向旋转90°，另一个限位组件300以自身的第三轴反向旋转90°，以使一对限位组件300的两个第二限位面340相向设置并形成第二容置腔500。
正向和反向中的其中一个为顺时针，另一个则为逆时针。
当然，M还可以是其他角度，比如20°、30°、45°、120°等，具体根据实际需求进行选择。
上述换型方法均需要先将一对限位组件300抽离第一容置腔400，调整一对限位组件300的状态后，再将一对限位组件300插入以形成第二容置腔500。
需要解释的是，形成第一容置腔400和形成第二容置腔500的一对限位组件300的定位基准不变，而上述换型方法中的第一轴、第二轴和第三轴仅限定了其延伸方向，也就是说，在调整一对限位组件300的状态后，存在两种情况，一是调整前后的一对限位组件300的定位基准共线，此时能够直接将一对限位组件300插入以形成第二容置腔500；另一种情况是调整前后的一对限位组件300的定位基准不 共线，则需要将一对限位组件300先平移一段距离后再插入以形成第二容置腔500。
参见图1至图3，本申请还公开了一种电池托盘，包括至少一对限位组件300和隔板组件，隔板组件包括支撑结构和至少两块分隔板200，支撑结构和至少两块分隔板200连接，限位组件300设有第一限位面330和第二限位面340，至少一对限位组件300与支撑结构或分隔板200连接，一对限位组件300的两个第一限位面330相向设置，以与两块分隔板200形成第一容置腔400，第一容置腔400的长度为L1，或一对限位组件300的两个第二限位面340相向设置，以与两块分隔板200形成第二容置腔500，第二容置腔500的长度为L2，L1不等于L2。
一对限位组件300的两个第一限位面330相向设置时，一对限位组件300和两块分隔板200合围形成第一容置腔400，第一容置腔400用于限位电池，一对限位组件300的两个第一限位面330和两块分隔板200为第一容置腔400的侧壁。一对限位组件300的两个第二限位面340相向设置时，一对限位组件300和两块分隔板200合围形成第二容置腔500，第二容置腔500用于限位电池，一对限位组件300的两个第二限位面340和两块分隔板200为第二容置腔500的侧壁。因为L1不等于L2，所以第一容置腔400和第二容置腔500所限位的电池的尺寸不同，从而使得电池托盘兼容不同尺寸的电池。
对于厂家来说，应用电池托盘具有以下优点，第一点，仅需要调整限位组件300的状态即可使得电池托盘可以承载和限位不同大小的电池，无需额外增加用于存放各种不同尺寸的限位组件300的存放区，从而避免存放区占用过多的厂房空间；第二点，由于不需要长距离地调度不同尺寸的限位组件300，可以减少物流线复杂程度。第三点，限位组件300调整状态前后所形成的第一容置腔400和第二容置腔500的中心位置不变，也就是定位基准不变，便于调节生产设备以对不同尺寸电池进行操作，从而保证不同尺寸电池的生产工序能够有效进行；第四点，通过限位组件300对电池的长度进行限位，分隔板200对电池的宽度进行限位，降低电池在电池托盘内发生位置偏移的可能。
限位组件300包括第一安装部310和限位部320，第一安装部310和限位部320连接，第一安装部310用于与支撑结构或分隔板200连接，第一限位面330和第二限位面340为同一限位部320上相互背离的两个端面或两个相互垂直的端面，即沿第一容置腔400/第二容置腔500沿长度方向上的两端面。第一安装部310和限位部320的结构较简单，第一安装部310和限位部320之间不相互干涉。
第一安装部310与支撑结构或分隔板200之间形成相互配合的滑轨和滑块机构，便于第一安装部310与支撑结构或分隔板200的连接和分拆。
限位组件300的第一安装部310和限位部320可以呈如图2和图3所示的L型，也可以设为如图4和图5所示的T型，还可以是梯形、矩形等其他形状。
限位组件300也可以为图10所示的T型以及如图11所示的矩形，限位组件300的第一安装部310设为竖直的安装通孔或安装柱，安装通孔或安装柱设于限位部320上。当然，为了避免限位组件300在电池的抵接时相对于安装部310转动，安装通孔和安装柱还可以设置相应的限位槽，以对不同安装状态的限位组件300进行定位。
也就是说，以与支撑结构和/或分隔板连接的第一安装部310的安装中心面为连接基准，该安装中 心面沿第一容置腔400/第二容置腔500的高度方向延伸，第一限位面330与连接基准的距离不等于第二限位面340与连接基准的距离即可实现安装限位组件300后，所形成的第一容置腔400的长度L1不等于第二容置腔500的长度L2。
在一实施例中，参见图2至图5，第一限位面330和第二限位面340为同一限位部320上相互背离的两个端面，即沿第一容置腔400/第二容置腔500沿长度方向上的两端面，优选地，第一限位面330和第二限位面340相互平行。
另一实施例中，第一限位面330和第二限位面340为同一限位部320上相邻且相互垂直的的两个端面。参见图10和图11，限位组件300包括第一安装部310和限位部320，第一安装部310设于限位部320上，限位部320设有第一限位面330和第二限位面340，第一限位面330和第二限位面340相邻设置，第一限位面330和第二限位面340与第一安装部310的距离不相等。
在其他实施例中，限位组件300还可以设置为如图6和图7所示，限位组件300包括两个第一安装部310和两个连接部，两个连接部的一端垂直连接，两个所述连接部的另一端分别与两个所述第一安装部310连接，两个连接部中的一个设有第一限位面330，与设有第一限位面330的连接部连接的第一安装部310上设有第二限位面340，第一限位面330和第二限位面340相互垂直。
优选地，为了使第一安装部310与支撑结构或分隔板200连接更加可靠，两个第一安装部310尺寸结构相同。
参见图8和图9，支撑结构包括托板100和设于托板100上的侧板，侧板与分隔板200连接，侧板和/或分隔板200与托板100连接，从而实现支撑结构与分隔板200的连接，采用该连接方式，可快速方便地将分隔板200、侧板和托板100三者装配起来。
分隔板200、侧板和托板100中的一个设有第二安装部，第二安装部用于与第一安装部310连接，第一安装部310和第二安装部中的一个为凹槽，另一个为凸起，凹槽与凸起相卡接，采用该连接方式，限位组件300可至少采用与分隔板200或侧板或托板100的三种连接方式。
由于第二安装部与分隔板200、侧板和托板100中的一个固定连接，即第二安装部的位置不变且仅有一个，因而本申请的电池托盘结构简单，无需加工多个第二安装部，能够有效降低电池托盘的加工难度和加工成本，也可以避免因存在空置的第二安装部而导致电池托盘对电池的夹持力不均衡的问题以及进一步降低电池在容置腔内部窜动的可能。采用本方案，仅需调整限位组件300状态即可实现对不同尺寸的电池的兼容。
参照图2至图7，限位组件300与分隔板200可拆卸连接。具体的，限位组件300的第一安装部310能够在分隔板200的凹槽的导引下实现限位组件300与分隔板200可拆卸连接。
参见图10至图13，限位组件300与托板100可拆卸连接。具体的，限位组件300和托板100中的一个设有安装杆，另一个设有安装孔，安装杆能够卡接于安装孔内，以实现限位组件300和托板100可拆卸连接。限位组件300为方体状，或限位组件300的横截面呈T形。
可以想到的是，限位组件300还可以与侧板可拆卸连接。
参见图8和图9，侧板包括多块固定块600，分隔板200的数量为多块，分隔板200的沿第一容置腔400的长度方向的两端分别与两个固定块600连接，优选地，固定块600与托板100连接，分隔板200通过固定块600实现与托板100的连接。多块固定块600、多块分隔板200和多个限位组件300沿图示的W方向和L方向排列设置，可形成多个纵横排列的第一容置腔400/第二容置腔500。即，电池托盘形成多行多列的用于容纳电池的第一容置腔400/第二容置腔500。
可以理解的是，分隔板200的一端与固定块600之间形成滑移机构，分隔板200的另一端与另一固定块600之间形成另一滑移机构，滑移机构便于分隔板200和固定块600的装配。滑移机构为相互配合的凹槽和凸起。
电池托盘还包括调节组件，调节组件与固定块600连接以调节相邻的分隔板200之间的距离，以使相邻的分隔板200夹紧或松开电池，从而将电池固定在托板100上。
调节组件包括导杆120、驱动组件130和两块挡板110，驱动组件130与两块挡板110的其中之一连接，与驱动组件130连接的挡板110上设有与导杆120相配合的导孔，导杆120与固定块600连接，驱动组件130用于驱动挡板110运动以调节相邻的分隔板200之间的距离，相邻的分隔板200将电池夹持并固定在托板100上。
本实施例中，导杆120和固定块600的列数均为五列，相邻两列导杆120或相邻两列固定块600之间设置一列分隔板200，所以分隔板200的列数和电池托盘所能承载的电池的列数均为四列。每列导杆120包括上中下设置的三根导杆120，固定块600上设有上中下分布的导孔，三根导杆120分别穿设于同一固定块600上的三个导孔。导杆120的横截面可为圆形或者方形。
分隔板200上设有多个透气孔210，透气孔210贯穿分隔板200的上下端面。透气孔210起到减重和流体空气的作用。电池加工化成的时候会发热，热量传递到分隔板200上，穿过透气孔210的空气可带走分隔板200的热量，有利于分隔板200和电池的降温。
托板100的上表面设有若干条左右分布的滑槽，滑槽向第一容置腔/第二容置腔的宽度方向延伸，滑槽的长度方向同时与导杆120的长度方向相同，分隔板200的下端和固定块600的下端均伸进滑槽，滑槽起到导向分隔板200和固定块600的作用，使得同一列的分隔板200/固定块600沿同一方向靠拢。
下面将描述电池托盘的具体工作原理。
针对第一限位面330和第二限位面340分设于限位组件300的相背离的两个端面的实施例中，调整限位组件300的方法包括：
第一种，请参照图2至图5、图12和图13，将第一位置和第二位置的限位组件300位置互换，以实现第一容置腔400/第二容置腔500的调整，第一位置和第二位置为沿第一容置腔400/第二容置腔500的长度方向上的两端。
第二种：请参照图2至图5，通过将一对限位组件300抽离第二安装部，使一对限位组件300分别绕自身的第二轴旋转180°后，将一对限位组件300插入第二安装部，以实现第一容置腔400/第二容置腔500的调整。第二轴沿第一容置腔400/第二容置腔500的宽度方向延伸且位于第一安装部310的安装 平面内，安装平面即第一安装部310和分隔板200连接时，第一安装部310的沿第一容置腔400/第二容置腔500高度方向延伸的中心面。
或者，请参照图12和图13，限位组件300的第一安装部310为设于限位部320上的安装孔或安装柱，第一安装部310与托板100连接，第一限位面330和第二限位面340与第一安装部310的距离不相等，通过将一对限位组件300抽离第二安装部，使一对限位组件300分别绕自身的第二轴旋转180°后，将一对限位组件300插入第二安装部，即可实现第一容置腔400/第二容置腔500的调整。第二轴沿第一容置腔400/第二容置腔500的宽度方向延伸且位于第一安装部310的沿第一容置腔400/第二容置腔500高度方向的中心面内。

或者，请参照图12和图13，限位组件300的第一安装部310为设于限位部320上的安装孔或安装柱，第一安装部310与托板100连接，第一限位面330和第二限位面340与第一安装部310的距离不相等，通过将一对限位组件300抽离第二安装部，使一对限位组件300分别绕自身的第一轴旋转180°后，将一对限位组件300插入第二安装部，即可实现第一容置腔400/第二容置腔500的调整。第一轴沿第一容置腔400/第二容置腔500的高度方向延伸且与第一安装部310的中心线共线。
针对第一限位面330和第二限位面340设于限位组件300的相互垂直的两个端面的实施例中，调整限位组件300的方法为：
请参照图6和图7，限位组件300包括两个第一安装部310和两个连接部，一个连接部的一端与另一个连接部垂直连接，另一端与第一安装部310连接，两个连接部中的一个设有第一限位面330，与设有第一限位面330的连接部连接的第一安装部310设有第二限位面340。一对限位组件300的每个限位组件300均通过一个第一安装部310与分隔板200连接以形成第一容置腔400，此时通过将一对限位组件300抽离第二安装部，使一对限位组件300中的一个限位组件300以自身的第三轴正向旋转90°，另一个限位组件300以自身的第三轴反向旋转90°后，将一对限位组件300的每个限位组件300的另一个第一安装部插入第二安装部，即可实现第一容置腔400/第二容置腔500的调整。第三轴沿第一容置腔400/第二容置腔500高度方向延伸，第三轴设于两个第一安装部310的中心线交点上，即当其中一个第一安装部310与分隔板200连接时，与分隔板200连接的第一安装部310的中心线指的是沿第一容置腔400/第二容置腔500的宽度方向上的中心线；另一安装部310的中心线指的是沿第一容置腔400/第二容置腔500的长度方向上的中心线。
