本申请涉及电池制造技术领域，特别是涉及一种加热固化设备及加热固化方法。
背景技术
新能源汽车具有噪音小、行驶稳定性好、零排放等优势，对于维护能源安全、维护环境以及保障社会可持续发展都有积极意义。因此，新能源汽车越来越受到人们的青睐。其中，电池作为新能源汽车的动力来源，成为新能源汽车最为重要的部件之一。电池在充放电过程中会产生大量的热，如果不及时散发出去，会影响电池自身以及汽车的安全性，也会影响电池的使用寿命。
目前，电池多采用液冷的方式进行散热，在电池的底部设置有水冷板作为液冷散热的部件，水冷板通常是通过热固胶粘贴在电池模块的底部。相关技术中，受限于粘贴工艺，导致水冷板的装配精度较低，给电池的后续生产过程造成麻烦，甚至会导致电池最终报废。

目前，从市场形势的发展来看，动力电池的应用越加广泛。动力电池不仅被应用于水力、火力、风力和太阳能电站等储能电源系统，而且还被广泛应用于电动自行车、电动摩托车、新能源汽车等电动交通工具，以及军事装备和航空航天等多个领域。随着动力电池应用领域的不断扩大，其市场的需求量也在不断地扩增。
以新能源汽车为例，其因噪音小、行驶稳定性好、零排放等优势，引起了越来越多的人的关注。电池是新能源汽车的心脏，是新能源汽车的动力来源。电池的使用安全性和使用 寿命是人们在选择新能源汽车时最关注的问题。电池在充放电过程中会产生大量的热，如果不及时散发出去，会影响电池自身以及汽车的安全性，也会影响电池的使用寿命。因此，对电池进行散热尤其重要。目前，电池多采用液冷的方式进行散热，在电池的底部设置有水冷板作为液冷散热的部件，水冷板通常是通过热固粘结胶粘贴在电池模块的底部。
通常，电池包括多个电池单体，电池单体经过串联或并联组成电池模块。相关技术中，电池模块与电池的侧板之间、以及电池模块与水冷板之间均是通过热固粘结胶进行粘贴的。首先，在电池模块与侧板之间涂覆粘结胶，以及在电池模块与水冷板之间涂覆粘结胶，然后将电池模块、侧板和水冷板等转移至加热装置，通过加热使粘结胶固化，从而实现电池模块与侧板之间的连接，以及电池模块和水冷板之间的连接。其中，加热装置包括侧部加热板和底部加热板，侧部加热板用于电池侧板的加热固化，底部加热板用于电池底部水冷板的加热固化。
本申请的发明人注意到，在加热固化工序中，由于水冷板和电池模块仅是放置在底部加热板上，因此，两者之间在放置时可能存在位置偏差，从而影响水冷板的装配精度。发明人还注意到，加热装置的侧部加热板在实施加热之前，需要先利用侧部加热板对电池的侧板实施加压，以要保证电池模块和侧板之间的粘结胶均匀扩散。在对侧板进行加压时，也会导致电池模块和水冷板之间发生位置窜动，进一步影响水冷板的装配精度。
可以理解，水冷板的装配精度较低，会给电池的后续生产工序造成很大的麻烦。例如，电池被汽车厂商采购以后，会进一步在电池上装配用于给水冷板供制冷剂的进、出液管，进、出液管先以压装的方式与水冷板中内置的接口对接，再进一步将进、出液管与接口连接。当水冷板在电池中的装配精度较低时，压装后的进、出液管就会产生位置偏差，无法与水冷板中内置的接口对接，当位置偏差较大时还会压在水冷板结构较为薄弱的位置，从而将水冷板压损，压损后的水冷板一旦投入使用会有制冷剂泄露至电池模块，导致电池模块报废的风险。
基于上述问题，为了能够提高水冷板的装配精度，发明人经过深入研究，设计出了一种加热固化设备，该加热固化设备在用于电池制造时可以通过托盘组件对电池模块和水冷板进行预组装，并且可在托盘组件保持对电池模块和水冷板的定位的状态下，对水冷板进行加热固化，从而实现水冷板的装配。由于在加热固化过程中，通过托盘组件保持对电池模块、水冷板的定位，因此可以显著提高水冷板的装配精度。
基于上述加热固化设备，还提出了一种加热固化方法，能够提高水冷板的装配精度。
本申请提出的加热固化设备可以但不限于用于对电池的水冷板进行加热固化。
本申请实施例公开的电池可以但不限用于车辆、船舶或飞行器等用电装置中。
本申请实施例中提到的电池是指包括一个或多个电池单体以提供更高的电压和容量的单一的物理模块。多个电池单体可经由极柱与导电连接片的焊接而被串联和/或并联在一起以应用于各种应用场合。在一些诸如电动汽车等的大功率应用场合，电池的应用包括三个层 次：电池单体、电池模组和电池包。电池模组是为了从外部冲击、热、振动等中保护电池单体，将一定数目的电池单体电连接在一起并放入一个框架中而形成的。电池包则是装入电动汽车的电池系统的最终状态。目前的大部分电池包是在一个或多个电池模组上装配电池管理系统(BMS)、热管理部件等各种控制和保护系统而制成的。随着技术的发展，电池模组这个层次可以被省略，也即，直接由电池单体形成电池包。这一改进使得电池系统的重量能量密度、体积能量密度得到提升的同时零部件数量显著下降。本申请中所提到的电池包括电池模组或电池包。
在电池中，电池单体可以是多个，多个电池单体之间可串联、并联或混联，混联是指多个电池单体中既有串联又有并联。多个电池单体之间可直接串联或并联或混联在一起，再将多个电池单体构成的整体容纳于箱体内；当然，电池也可以是多个电池单体先串联或并联或混联组成电池模块形式，多个电池模块再串联或并联或混联形成一个整体，并容纳于箱体内。电池还可以包括其他结构，例如，电池还可以包括汇流部件，用于实现多个电池单体之间的电连接。其中，每个电池单体可以为二次电池或一次电池；还可以是锂硫电池、钠离子电池或镁离子电池，但不局限于此。电池单体可呈圆柱体、扁平体、长方体或其它形状等。
如图1至图4所示，本申请第一方面的实施例提出了一种加热固化设备。该加热固化设备包括加热组件100和托盘组件200。具体地，加热组件100包括支撑架110和设置在支撑架110上的发热板120。托盘组件200包括托盘210、第一定位件220和第二定位件230，托盘210用于承载电池模块和待安装于电池模块的水冷板，第一定位件220和第二定位件230均设置在托盘210上，第一定位件220用于对水冷板进行定位，第二定位件230用于对电池模块进行定位。其中，发热板120配置为对装载在托盘组件200上的电池模块和水冷板进行加热。
加热组件100是指能够产生高温，以对待加热对象进行加热的结构。加热组件100在工作时产生的热量可传递给电池模组和水冷板，从而促进涂覆在电池模组和水冷板之间的粘结胶固化。
发热板120是指加热组件100中直接产生高温的板状部件。具体地，发热板120可以是将电能转换为热量的电加热板，也可以是将电磁能转换为热量的电磁加热板。
支撑架110是指设置在发热板120的底部，用于支撑发热板120的架体。由于支撑架110具有一定的高度，使得发热板120可以处于合适的高度位置。另外，支撑架110还用于使加热组件100具有一定的结构强度和结构刚度，使得加热组件100能够承载一定的重量，进而使得电池模组和水冷板放置加热板上时，加热组件100的结构不会被破坏，也不会发生变形，始终维持结构的稳定性。支撑架110可以采用刚性的金属件制成，不仅稳固，而且结实耐用。
托盘组件200是指可以承载电池模块和水冷板，并可带着电池模块和水冷板在不同的 工序进行流转的部件。其中，托盘210为托盘组件200的主体结构，电池模块和水冷板的重量主要有托盘210承载。
第一定位件220是指安装在托盘210上的并且可以对水冷板进行限位的结构件，当水冷板装载在托盘210上之后，第一定位件220可以使水冷板在托盘210上保持在固定的位置而不会发生窜动。例如，示例性地，第一定位件220可以是定位柱、定位销或定位块等。
第二定位件230是指安装在托盘210上的并且可以对电池模块进行限位的结构件，当电池模块装置在托盘210上之后，第二定位件230可以使电池模块在托盘210上保持在固定的位置而不会发生窜动。例如，示例性地，第二定位件230可以是定位柱、定位销或定位块等。
根据本申请实施例的加热固化设备，包括加热组件100和托盘组件200，托盘210可以承载电池模块和水冷板，也就是说，电池模块和水冷板可以在托盘210上实现预组装。具体地，可以先将水冷板放置在托盘210上，并通过托盘210上的第一定位件220对水冷板进行定位，然后再水冷板和/或电池模块的底部涂覆粘结胶，之后再将电池模块放置在托盘210上，并通过托盘210上的第二定位件230对电池模块进行定位。通过托盘组件200将电池模块和水冷板一同转移至加热组件100处，在托盘组件200保持对电池模块和水冷板定位的状态下，通过加热组件100对水冷板进行加热，促进粘结胶固化，从而实现水冷板与电池模块之间的装配。由于在加热固化的过程中，托盘组件200始终维持电池模块以及水冷板的位置不变，因此，可以显著提高水冷板的装配精度。
在一些实施例中，如图2所示，托盘210设置有镂空区域211，镂空区域211用于使水冷板能够接触到发热板120。
镂空区域211为在托盘210上形成的孔槽结构。
在托盘210上设置有镂空区域211，当电池模块和水冷板装载托盘210上以后，通过镂空区域211，可以使水冷板直接与发热板120接触，从而可以更有效地利用发热板120发出的热量，避免热能的浪费。
在一些实施例中，第一定位件220的数量为多个，多个第一定位件220位于镂空区域211的相对的两侧，且靠近镂空区域211设置。第二定位件230的数量为多个，多个第二定位件230位于镂空区域211的另外相对的两侧，且靠近镂空区域211设置。
在该实施例中，第一定位件220的数量为多个，通过多个第一定位件220对水冷板进行限位，可以提高水冷板的位置稳定性和姿态稳定性，从而确保水冷板不会发生平移和转动。类似地，第二定位件230的数量为多个，通过多个第二定位件230对电池模块进行限位，可以提高电池模块的位置稳定性和姿态稳定性，从而确保电池模块不会发生平移和转动。另外，多个第一定位件220设置在镂空区域211的相对的两侧，多个第二定位件230设置在镂空区域211的另外相对的两侧，使得第一定位件220和第二定位件230不会相互干涉。
在一些实施例中，如图2、图3所示，托盘组件200还包括多个顶紧机构240，顶紧机构240设置在托盘210上，顶紧机构240用于与电池模块的侧壁相抵，以将电池模块固定在托盘210上。
顶紧机构240是指具有弹性的可以伸缩的机构，通常具有一个可伸缩端，在弹性作用下，可伸缩端能够与电池模块的侧壁紧密相抵。
可以理解的是，与第一定位件220和第二定位件230相对应地，在水冷板上设置有用于与第一定位件220相配合的定位孔，在电池模块上设置有用于与第二定位件230相配合的定位孔。尽管通过定位孔与第二定位件230的配合，使得电池模块定位在托盘210上，但是电池模块与托盘210之间依然可能存在有间隙。顶紧机构240的设置，其目的是消除上述间隙。具体地，在电池模块装载在托盘210上之后，使顶紧机构240与电池模块的侧壁紧密相抵，这样即可消除电池模块与托盘210之间的间隙，从而将电池模块固定在托盘210上，以便于进一步提高水冷板与电池模块的装配精度。
在一些实施例中，顶紧机构240的数量为多个，多个顶紧机构240分布于镂空区域211的相对的两侧。如此设置，当利用多个顶紧机构240顶紧电池模块时，电池模块相对的两侧都会受到来自于顶紧机构240的作用力，使得电池模块受力均匀，这样更有利于保持电池模块定位准确。
可以理解的是，电池模块通常为长方体结构，其具有四个侧面，其中两个侧面为大面，另外两个侧面为小面。在一个实施例中，多个顶紧机构240分布于大面的相对的两侧。当然，在另外一个实施例中，多个顶紧机构240也可以分布于小面的相对的两侧。
在一些实施例中，如图3所示，顶紧机构240包括安装块241、导轨242、滑动顶紧块244和弹性元件245。其中，安装块241固定连接在托盘210上，导轨242固定连接在托盘210上，滑动顶紧块244以滑动配合的方式连接于导轨242，弹性元件245设置在滑动顶紧块244和安装块241之间。
安装块241是指固定设置在托盘210上的刚性结构体，保证顶紧机构240与托盘210连接的可靠性。
滑动顶紧块244是指可直接与电池模块的侧壁接触，以对电池模块施加压力的结构件。
导轨242，也可以称之为滑轨或轨道，是指设置在托盘210上的用于限定滑动顶紧块244的运动轨迹的结构。本申请实施例中的滑动顶紧块244实现的是直线往复运动。示例性地，滑动顶紧块244可以进一步包括滑动部2441和顶紧部2442，顶紧部2442为滑动顶紧块244上的用于直接与电池模块的侧壁接触的部分，滑动部2441为与导轨242滑动配合的部分。
弹性元件245是指可以提供弹性力给滑动顶紧块244，以使滑动顶紧块244产生向靠近电池模块的方向运动的运动趋势。作为一种实施方式，弹性元件245可以例如为弹簧。
在电池模块装载于托盘210的情况下，弹性元件245作用于滑动顶紧块244，使滑动顶紧块244保持有向电池模块所在方向运动的运动趋势，从而使滑动顶紧块244与电池模块的侧壁紧密相抵。并且，在导轨242的导向作用下，滑动顶紧块244的运动方向不会发生偏离，由此，保证滑动顶紧块244能够有效地为电池模块提供顶紧作用。
在一些实施例中，如图1、图4、图5至图10所示，加热固化设备还包括托盘转运机构300，托盘转运机构300用于将托盘组件200转移至加热组件100，以使托盘组件200上的水冷板放置在发热板120上。
托盘转运机构300是指能够带动托盘组件200运动的机构，使托盘组件200能够在不同的加工工位之间进行转移。
在前置工序中，可以将水冷板和电池模块分别装载在托盘组件200上，并在水冷板和电池模块之间涂覆粘结胶，从而使水冷板和电池模块在托盘组件200上实现预组装。之后再利用托盘转运机构300将承载有电池模块和水冷板的托盘组件200转移至加热组件100所在位置，并且使托盘组件200上的水冷板放置在发热板120上，以利用发热板120对电池模块和水冷板进行加热，促使粘结胶固化。通过设置托盘转运机构300，便于使电池模块和水冷板在预组装工序位置和加热位置之间进行转移。
在一些实施例中，如图8至图10所示，托盘转运机构300包括升降架310和直线运动缸320，升降架310用于带动托盘组件200升降，以使托盘组件200上的水冷板放置在发热板120上。直线运动缸320设置在升降架310上，直线运动缸320用于拉动托盘组件200，以使托盘组件200沿水平方向运动至升降架310上。
升降架310是指可实现上升和下降功能的架体。可以理解的是，升降架310包括动力部件313和可升降结构314，其中，动力部件313可以是气缸、液压缸或直线电机等用于提供直线运动的动力装置。可升降结构314与动力部件的运动端连接，从而在动力部件313的驱动下，使得可升降结构314能够上升或者下降。
直线运动缸320是指用于提供直线运动的动力缸，直线运动缸320可以是气缸、液压缸等。直线运动缸320根据是否自带可输出直线运动的推拉杆，可分为无杆运动缸和有杠运动缸，顾名思义，无杆运动缸不自带可输出直线运动的推拉杆，而有杆运动缸自带有可输出直线运动的推拉杆。
在预组装工序位置，电池模块和水冷板装载在托盘组件200上，从而完成预组装。然后可以通过外部的连接杆将托盘组件200与直线运动缸320连接起来，然后启动直线运动缸320。直线运动缸320在运行时通过连接杆拉动托盘组件200，使得托盘组件200从预组装工序位置转移至升降架310上，然后拆下连接杆，再通过控制升降架310下降，从而使托盘组件200上的水冷板放置在发热板120上，以便于对水冷板进行加热固化处理。
在一些实施例中，如图4至图6，以及图9、图10所示，在升降架310的顶部设置有 多个第一支撑组件311，第一支撑组件311用于支撑托盘组件200。加热固化设备还包括固定架，在固定架上设置有多个第二支撑组件400，第二支撑组件400用于支撑托盘组件200。固定架的高度可以配置为，当托盘组件200下降至落到第二万向轴轴承上时，托盘组件200上的水冷板刚好与发热板120接触。
支撑组件是指利用球型连接实现不同轴的动力传送的机械结构，例如，支撑组件可以是万向轴承。
固定架是指高度保持不变的架体。
在该实施例中，升降架310的顶部设置有多个第一支撑组件311，在直线运动缸320拉动托盘组件200水平运动的过程中，托盘组件200可以在第一支撑组件311上滑动，由此，可以减小托盘组件200运动过程中的摩擦力，使托盘组件200运动顺畅。
加热固化设备还包括固定架，固定架上设置有多个第二支撑组件400，当托盘210运动组件在直线运动缸320拉动下运动至升降架310上后，升降架310带动托盘组件200下降，当升降架310下降至使第一支撑组件311与第二支撑组件400高度平齐时，托盘组件200同时支撑在第一支撑组件311和第二支撑组件400上，并且托盘组件200上的水冷板刚好与发热板120接触。之后，即可利用发热板120对水冷板进行加热固化处理。
在一些实施例中，升降架310上设置有多个通孔316，在加热固化设备的高度方向上，第二支撑组件400与通孔316相对设置，且通孔的内径大于第二支撑组件400的外径。
在升降架310下降的过程中，第二支撑组件400可以通过升降架310上的通孔显露出来，随着升降架310的继续下降，最终使第一支撑组件311与第二支撑组件400高度平齐。
在一些实施例中，如图1、图8所示，加热固化设备还包括机架500，加热组件100、升降架310、固定架等均设置在机架500上。如此设置，使得加热固化设备的各部件集成在一起。

根据本申请实施例的加热固化设备，包括加热组件100和托盘组件200，托盘210可以承载电池模块和水冷板，也就是说，电池模块和水冷板可以在托盘210上实现预组装。具体地，可以先将水冷板放置在托盘210上，并通过托盘210上的第一定位件220对水冷板进行定位，然后再水冷板和/或电池模块的底部涂覆粘结胶，之后再将电池模块放置在托盘210上，并通过托盘210上的第二定位件230对电池模块进行定位。通过托盘组件200将电池模块和水冷板一同转移至加热组件100处，在托盘组件200保持对电池模块和水冷板定位的状态下，通过加热组件100对水冷板进行加热，促进粘结胶固化，从而实现水冷板与电池模块之间的装配。由于在加热固化的过程中，托盘组件200始终维持电池模块以及水冷板的位置不变，因此，可以显著提高水冷板的装配精度。
另外，在托盘210上设置有镂空区域211，当电池模块和水冷板装载托盘210上以后，通过镂空区域211，可以使水冷板直接与发热板120接触，从而可以更有效地利用发热板120发出的热量，避免热能的浪。
再者，在前置工序中，可以将水冷板和电池模块分别装载在托盘组件200上，并在水冷板和电池模块之间涂覆粘结胶，从而使水冷板和电池模块在托盘组件200上实现预组装。之后再利用托盘转运机构300将承载有电池模块和水冷板的托盘组件200转移至加热组件100所在位置，并且使托盘组件200上的水冷板放置在发热板120上，以利用发热板120对电池模块和水冷板进行加热，促使粘结胶固化。通过设置托盘转运机构300，便于使电池模块和水冷板在预组装工序位置和加热位置之间进行转移。
