背景技术
在锂离子电池的生产过程中，极片生产完后，采用卷绕或者叠片的方式将正极极片、负极极片和隔膜组装形成电芯，然后再对电芯进行热压以对电芯整形。
在电芯的热压过程中，通常需要夹爪将组装形成的电芯移动放置到热压机上，如图1所示，夹爪01的夹持部011通常为凹槽形状，在夹爪01夹持电芯200时，电芯200的边缘部分嵌设在凹槽中，以使夹爪01能够较为牢固的夹持电芯200。热压机通常包括相对设置的上热压板和下热压板，其中，下热压板包括沿水平方向依次排列的第一下热压板、第二下热压板以及第三下热压板，第二下热压板连接有升降结构，以使得第二下热压板能够沿竖直方向移动，以在夹爪01夹持着电芯200放置在下热压板上时，第二下热压板在升降结构的驱动下上升至一定高度，以在夹爪01将电芯200放置到第二下热压板上时，电芯200的边缘是悬空于第二下热压板的外侧的，使得夹爪01不易与第一下热压板、第二下热压板以及第三下热压板出现接触的情况，方便了夹爪01对电芯200的松开和移动。

并且，驱动组件驱动第一支撑组件和第二支撑组件沿第一水平方向相背移动，使得第一支撑组件和第二支撑组件位于下热压板的沿第一水平方向的两侧时，位于上热压板沿第一水平方向的相对两侧的辅助压板可与上热压板同步移动，并先于上热压板与辅助上下料模块抵接，此时，辅助压板与上热压板继续同步移动，使得辅助压板能够挤压辅助上下料模块离开初始位置沿竖直方向向下移动，以使承载膜贴合于下热压板，使得承载于承载膜上的待热压的电芯能够承载于下热压板上，以在上热压板下压时能够对待热压的电芯施加较大的力进行热压，相比于将下热压板设置为三个依次排列的下热压板，能够有效防止电芯在热压的过程中出现压痕，提高了电芯的热压质量。
另外，电芯完成热压后，辅助压板与上热压板可同步向上移动，以解除对辅助上下料模块的挤压，使得第一支撑组件和第二支撑组件能够在外力的作用 下向上移动，以使承载膜能够悬于下热压板的上方，使得热压后的电芯能够悬于下热压板的正上方，此时，驱动组件可驱动第一支撑件和第二支撑组件相向移动以相互靠近并位于下热压板的正上方，使得热压后的电芯的沿第一水平方向的边缘部分能够处于悬空状态，以在夹爪对热压后的电芯进行夹持时，能够避免对电芯造成划伤等伤害，提高了热压机对电芯的热压质量。

本申请提供了一种热压机，能够有效避免电芯在热压的过程中出现压痕的情况，提高了热压机对电芯的热压质量。
下面将结合具体实施例和附图对本申请的技术方案进行详细说明。
实施例一
本申请实施例提供了一种热压机，如图2-图5所示，包括机架1、上热压板2a、下热压板2b、辅助上下料模块3以及辅助压板4。其中，上热压板2a沿 竖直方向可移动地设置于机架1。下热压板2b设置于机架1上且与上热压板2a相对设置。上热压板2a沿竖直方向在下热压板2b上的投影位于下热压板2b上。辅助上下料模块3包括驱动组件31、第一支撑组件32a、第二支撑组件32b以及承载膜32c。驱动组件31设置于机架1，驱动组件31的驱动端与第一支撑组件32a和第二支撑组件32b连接。驱动组件31用于驱动第一支撑组件32a和第二支撑组件32b沿第一水平方向(如图2中X所示的方向)相向或者相背移动，第一支撑组件32a和第二支撑组件32b用于支撑承载膜32c，并将承载膜32c张紧于上热压板2a和下热压板2b之间。辅助压板4位于上热压板2a沿第一水平方向的相对的两侧，并与上热压板2a同步移动。第一支撑组件32a和第二支撑组件32b位于下热压板2b的沿第一水平方向的两侧时，辅助压板4与上热压板2a同步移动，并先于上热压板2a与辅助上下料模块3抵接，以使位于第一支撑组件32a和第二支撑组件32b之间的承载膜32c贴合于下热压板2b。
在本实施例中，上热压板2a沿竖直方向可移动地设置于机架1，下热压板2b与上热压板2a相对设置，且上热压板2a沿竖直方向在下热压板2b上的投影位于下热压板2b上，使得上热压板2a和下热压板2b之间能够形成热压空间，以在上热压板2a相对于机架1向下热压板2b的方向移动时，能够对待热压的电芯200进行热压。
辅助上下料模块3中，驱动组件31设置于机架1，驱动组件31的驱动端与第一支撑组件32a和第二支撑组件32b连接。驱动组件31用于驱动第一支撑组件32a和第二支撑组件32b沿第一水平方向相向或者相背移动，以使第一支撑组件32a和第二支撑组件32b能够位于下热压板2b的正上方或下热压板2b的沿第一水平方向的两侧。第一支撑组件32a和第二支撑组件32b用于支撑承载膜32c，并将承载膜32c张紧于上热压板2a和下热压板2b之间，使得承载膜 32c能够承载待热压的电芯200，以在驱动组件31驱动第一支撑组件32a和第二支撑组件32b沿第一水平方向相向移动时，使得第一支撑组件32a和第二支撑组件32b能够相互靠近。此时，待热压的电芯200可承载于第一支撑组件32a、第二支撑组件32b以及承载膜32c上，使得待热压的电芯200的放置能够较为平稳，同时待热压的电芯200的边缘部分能够悬空于承载膜32c之外，以及能够悬空于下热压板2b的正上方，使得待热压的电芯200的被夹爪夹持的部分能够处于悬空状态，以在夹爪松开对待热压的电芯200的夹持时，夹爪能够稍微下移一定的距离(如2mm、5mm等)，避免了夹爪在松开对待热压的电芯200的夹持并移开的过程中拖拽电芯200或者划伤电芯200，能够有效提高热压机100对电芯200的热压质量。
并且，驱动组件31驱动第一支撑组件32a和第二支撑组件32b沿第一水平方向相背移动，使得第一支撑组件32a和第二支撑组件32b位于下热压板2b的沿第一水平方向的两侧时，辅助压板4可与上热压板2a同步移动，并先于上热压板2a与辅助上下料模块3抵接，此时，辅助压板4与上热压板2a继续同步移动，使得辅助压板4能够挤压辅助上下料模块3离开初始位置沿竖直方向向下移动，以使承载膜32c贴合于下热压板2b，使得承载于承载膜32c上的待热压的电芯200能够承载于下热压板2b上，以在上热压板2a下压时能够对待热压的电芯200施加较大的力进行热压，相比于将下热压板2b设置为三个依次排列的下热压板2b，能够有效防止电芯200在热压的过程中出现压痕，提高了电芯200的热压质量。
另外，电芯200完成热压后，辅助压板4与上热压板2a可同步向上移动，以解除对辅助上下料模块3的挤压，使得第一支撑组件32a和第二支撑组件32b能够在外力的作用下向上移动，以使承载膜32c能够悬于下热压板2b的上方， 使得热压后的电芯200能够悬于下热压板2b的正上方，此时，驱动组件31可驱动第一支撑件和第二支撑组件32b相向移动以相互靠近并位于下热压板2b的正上方，使得热压后的电芯200的沿第一水平方向的边缘部分能够处于悬空状态，以在夹爪对热压后的电芯200进行夹持时，能够避免对电芯200造成划伤等伤害，提高了热压机100对电芯200的热压质量。
上述的上热压板2a沿竖直方向在下热压板2b上的投影位于下热压板2b上，可以是上热压板2a沿竖直方向在下热压板2b上的投影完全位于下压热板上，即上热压板2a的板面的尺寸小于或者等于下热压板2b的板面的尺寸；也可以是，上热压板2a沿竖直方向在下热压板2b上的投影位于下热压板2b上且延伸出下热压板2b的板面，即上热压板2a的板面的尺寸大于下热压板2b的板面的尺寸，在此并不做限定。优选地，上热压板2a的板面尺寸可与下热压板2b的板面尺寸相同。
第一支撑组件32a和第二支撑组件32b位于下热压板2b的上方，可以是，第一支撑组件32a和第二支撑组件32b悬于下热压板2b的上方，也可以是，第一支撑组件32a和第二支撑组件32b刚好与下热压板2b的上表面相接触，在此并不做限定，只要能够使承载于第一支撑组件32a、第二支撑组件32b以及承载膜32c上的电芯200悬于下热压板2b即可。
可选地，如图3所示，辅助压板4朝向下热压板2b的一端凸出于上热压板2a，且辅助压板4凸出于上热压板2a的厚度与电芯200的厚度相同，或者，辅助压板4凸出于上热压板2a的厚度大于电芯200的厚度。
由此，可使得上热压板2a向下移动时，辅助压板4能够先与辅助上下料模块3相抵接并挤压辅助上下料模块3向下移动，以使第一支撑组件32a和第二支撑组件32b之间的承载膜32c贴合于下热压板2b上，能够使得上热压板2a 和辅助压板4仅进行一次或者很少次数向下移动的动作，即能够完成对电芯200的热压，操作简单快捷。
上述的，辅助压板4朝向下热压板2b的一端凸出于上热压板2a厚度与电芯200的厚度的差值小于电芯200的厚度时，易使得上热压板2a向下移动的距离较大，导致上热压板2a对电芯200的挤压的尺寸较大，造成热压后的电芯200中的正、负极片以及隔膜之间的间隙较小，不利于后续对电芯200进行注液的操作，甚至对电芯200的性能造成不好的影响。
其中，辅助压板4凸出于上热压板2a的厚度大于电芯200的厚度时，二者之间的差值可为A，0.5mm≤A≤1.5mm，使得热压后的电芯200的厚度能够在热压后的电芯200的预设厚度范围内，可使得热压后的电芯200具有较好的质量。
另外，辅助压板4朝向下热压板2b的一端凸出于上热压板2a厚度与电芯200的厚度的差值较大时，如大于1.5mm时，易使得上热压板2a向下移动的距离较小，导致上热压板2a对电芯200的挤压的尺寸较小，造成热压后的电芯200中的正、负极片以及隔膜之间的间隙较大，同样会对电芯200的质量造成影响。因此，辅助压板4朝向下热压板2b的一端凸出于上热压板2a，凸出的厚度与电芯200的厚度相同，或者凸出的厚度与电芯200的厚度的差值范围为0.5mm～1.5mm，可使得热压后的电芯200具有较好的质量。
上述的辅助压板4与上热压板2a同步移动，并先于上热压板2a与辅助上下料模块3抵接，以使第一支撑组件32a和第二支撑组件32b之间的承载膜32c贴合于下热压板2b。其中，位于第一支撑组件32a和第二支撑组件32b之间的承载膜32c在辅助压板4的作用下移动、贴合于下热压板2b的过程中，可以仅是第一支撑组件32a和第二支撑组件32b移动，以带动位于第一支撑组件32a和第二支撑组件32b之间的承载膜32c移动、并贴合于下热压板2b上；也可以 是，辅助上下料模块3的整体移动，以使第一支撑组件32a和第二支撑组件32b随着移动，从而带动位于第一支撑组件32a和第二支撑组件32b之间的承载膜32c移动、并贴合于下热压板2b上。
在一些实施例中，当仅是第一支撑组件32a和第二支撑组件32b在辅助压板4的作用下移动时：第一支撑组件32a和第二支撑组件32b中可设有弹性件33，第一支撑组件32a和第二支撑组件32b位于下热压板2b的沿第一水平方向的两侧时，辅助压板4先于上热压板2a与第一支撑组件32a和第二支撑组件32b抵接，并压缩弹性件33，以使第一支撑组件32a和第二支撑组件32b之间的承载膜32c贴合于下热压板2b。
由此，当辅助压板4与上热压板2a一起向下移动，与第一支撑组件32a和第二支撑组件32b相抵接，并继续向下移动、挤压第一支撑组件32a和第二支撑组件32b向下移动时，弹性件33可产生压缩变形，以对第一支撑组件32a和第二支撑组件32b的移动起到缓震的效果，提高了第一支撑组件32a和第二支撑组件32b的向下移动的平稳性；同时，当辅助压板4向上移动时，被压缩的弹性件33还可带动第一支撑组件32a和第二支撑组件32b向上移动，以恢复至初始位置，结构简单易于实现。
其中，弹性件33可以是弹簧、泡棉、硅胶块等中的任一种，在此并不做限定。
另外，弹性件33的数量可以是一个、两个或者更多个，在此也不做限定。
在另一些实施例中，当辅助压板4抵接、并挤压辅助上下料模块3的整体移动时，如图3-图5所示，辅助上下料模块3沿竖直方向可移动地设置于机架1，辅助上下料模块3还包括弹性件33，弹性件33设置于辅助上下料模块3背离辅助压板4的一侧，弹性件33用于为辅助上下料模块3提供复位至初始位置 的力。
需要解释说明的是，上述的初始位置是指辅助上下料模块3在未被辅助压板4挤压向下移动时，第一支撑组件32a和第二支撑组件32b所处于的位置。
由此，当辅助压板4挤压辅助上下料模块3并向下移动时，弹性件33可产生压缩变形，以对辅助上下料模块3的整体的移动起到缓震的效果，提高了辅助上下料模块3的向下移动的平稳性，从而能够使得承载膜32c的移动具有较好的平稳性；同时，当辅助压板4向上移动时，被压缩的弹性件33还可带动辅助上下料模块3向上移动，以恢复至初始位置，结构简单易于实现。
其中，弹性件33设置于辅助上下料模块3背离辅助压板4的一侧，弹性件33设置于辅助上下料模块3的位置可具有多种，如，弹性件33可设置于驱动组件31的背离辅助压板4的一侧，使得被压缩变形的弹性件33能够驱动驱动组件31向上移动，此时，驱动组件31可带动辅助上下料模块3中的其它部件一起向上移动，如可带动第一支撑组件32a和第二支撑组件32b等一起向上移动；也可以是，弹性件33设置于辅助上下料模块3中的其它部件的背离辅助压板4的一侧，如，设置于第一支撑组件32a或者第二支撑组件32b的背离辅助压板4的一侧，此时，在此并不做限定。
可选地，如图3-图5所示，辅助上下料模块3还包括两个压紧组件5，两个压紧组件5分别位于下热压板2b沿第一水平方向的两侧，且位于下热压板2b与驱动组件31之间，承载膜32c的两端分别设置于两个压紧组件5上，压紧组件5用于压紧或者松开承载膜32c的两端，以使承载膜32c张紧或者松弛。
由此，通过将承载膜32c的两端分别设置于两个压紧组件5上，压紧组件5压紧或者松开承载膜32c的两端，以使承载膜32c能够张紧或者松弛，以在承载膜32c悬于下热压板2b的上方时，承载膜32c的两端能够被压紧组件5压紧， 使得承载膜32c处于张紧状态，在承载膜32c贴合于下热压板2b上，上热压板2a对电芯200进行热压时，承载膜32c的两端能够被压紧组件5松开，使承载膜32c处于松弛状态，以使得电芯200再被热压时能够始终处于下热压板2b上，同时也可防止电芯200再被热压时因承载膜32c处于张紧状态而出现被撕裂的情况。
其中，压紧组件5可通过滑动部件沿竖直方向可移动地设置于机架1上，如，压紧组件5的朝向机架1的一侧可设置滑块，机架1的朝向压紧组件5的一侧可设置沿竖直方向延伸的滑槽，滑块可滑动地嵌设于滑槽中，以使压紧组件5能够沿滑槽相对于机架1上下移动，防止了压紧组件5沿竖直方向移动时出现偏移的情况；也可以在压紧组件5的朝向机架1的一侧设置滚珠，压紧组件5通过滚珠沿竖直方向与机架1移动连接，减小了压紧组件5与机架1之间的摩擦阻力，使得压紧组件5沿竖直方向的移动能够较为流畅。
可选地，如图3-图5所示，压紧组件5与第一支撑组件32a和第二支撑组件32b连接，弹性件33设置于压紧组件5的背离辅助压板4的一侧，弹性件33用于为压紧组件5提供复位的力。
由此，在电芯200完成热压后，辅助压板4向上移动时，被压缩的弹性件33可带动压紧组件5向上移动复位，压紧组件5与第一支撑组件32a和第二支撑组件32b连接，使得压紧组件5能够带动第一支撑组件32a和第二支撑组件32b向上移动复位至原始位置，相比于将弹性件33设置于可沿第一水平方向移动的第一支撑组件32a和第二支撑组件32b上，使得第一支撑组件32a和第二支撑组件32b在组装时可无需考虑与弹性件33的连接，降低了组装难度。
在一些实施例中，如图3-图5所示，驱动组件31沿竖直方向可移动地设置于机架1，压紧组件5包括连接板(图中未示出)、压紧气缸51和压紧块52， 连接板可移动地设置于机架1，压紧气缸51与压紧块52均设置于连接板，压紧块52与压紧气缸51的活塞杆相对设置，承载膜32c的端部设置于压紧块52与活塞杆之间，活塞杆与压紧块52相抵接时，承载膜32c处于张紧状态，活塞杆与压紧块52相远离时，承载膜32c处于松弛状态。
由此，当压紧气缸51的活塞杆伸出并与压紧块52相抵接时，即可将承载膜32c的端部压紧在活塞杆与压紧块52之间，使得承载膜32c能够处在张紧状态；当压紧气缸51的活塞杆缩回并与压紧块52之间具有间隙时，即能够松开对承载膜32c的端部的压紧，使得承载膜32c能够处在松弛状态，操作简单方便。
其中，压紧气缸51也可以是压紧液压缸，还可以是压紧电缸，在此并不做限定。
上述的驱动组件31沿竖直方向可移动地设置于机架1，驱动组件31的驱动端还与第一支撑组件32a和第二支撑组件32b连接，当电芯200完成热压后，第一支撑组件32a和第二支撑组件32b向上移动时，可以是，驱动组件31上设置有用于驱动向上移动的向上驱动件，也可以是，第一支撑组件32a和第二支撑组件32b上设置有用于驱动向上移动的向上驱动件，如气缸、弹性件等，第一支撑组件32a和第二支撑组件32b带动驱动组件31向上移动；还可以是，压紧组件5在弹性件33的驱动下向上移动时，带动驱动组件31向上移动，在此并不做限定。
并且，驱动组件31沿竖直方向可移动地设置于机架1，可使得驱动组件31可与第一支撑组件32a和第二支撑组件32b同步上下移动，使得驱动组件31与第一支撑组件32a和第二支撑组件32b之间的连接能够较为稳定牢固。
在另一些实施例中，压紧组件5也可包括连接板、压紧电机、丝杆、可滑 动地套设于丝杆上的螺母以及压紧块52，连接板可移动地设置于机架1，压紧电机、丝杆与压紧块52均设置于连接板，丝杆沿竖直方向延伸，压紧电机的驱动端与丝杆连接，压紧块52与螺母设置，承载膜32c的端部设置于压紧块52与螺母之间，以在压紧电机启动后，丝杆转动，螺母沿丝杆滑动至与压紧块52相抵接，将承载膜32c的端部压紧在螺母与压紧块52之间，使得承载膜32c能够处于张紧状态，在丝杆向相反的方向转动时，螺母朝远离压紧块52的方向滑动，螺母和压紧块52松开对承载膜32c的压紧，使得承载膜32c能够处于松弛状态。
可选地，如图3-图5所示，压紧组件5与辅助压板4相对设置，且压紧组件5的朝向辅助压板4的一侧设置有抵接件6，抵接件6用于在上热压板2a下压时与辅助压板4相抵接。
由此，辅助压板4向下移动与抵接件6相抵接时，可挤压抵接件6向下移动，抵接件6带动压紧组件5向下移动，防止了辅助压板4直接与压紧组件5相抵接而对压紧组件5对承载膜32c的压紧和松开造成影响。
其中，抵接件6的朝向辅助压板4的一侧还可设置有弹性垫，以在辅助压板4与抵接件6相抵接时，辅助压板4与抵接件6之间为软接触，防止了因辅助压板4在抵接、挤压抵接件6时抵接件6被撞击而受到损伤。

其中，第一驱动气缸311和第二驱动气缸313也可以是驱动电缸，还可以是驱动液压缸，在此并不做限定。
上述的第一驱动气缸311的活塞杆与第一支撑组件32a连接，可以是，第一支撑组件32a朝向线轨312的一侧设置有滑块，滑块与线轨312滑动连接，第一驱动气缸311的活塞杆与滑块连接。同样的，第二驱动气缸313的活塞杆与第二支撑组件32b连接，可与第一驱动气缸311的活塞杆与第一支撑组件32a的连接大致相同，具体可参考上述，在此不再进行赘述。
在另一种驱动组件31可能实现方式中，驱动组件31包括第一驱动电机、第二驱动电机、沿第一水平方向延伸的第一丝杆和第二丝杆，第一丝杆和第二丝杆均沿竖直方向可移动地设置于机架1，第一支撑组件32a螺纹连接在第一丝杆上，第一驱动电机的驱动端与第一丝杆连接，第一驱动电机用于驱动第一丝杆旋转，从而使得第一支撑组件32a沿第一丝杆移动；第二丝杆与第一丝杆沿第一丝杆的延伸方向相对设置，且第二丝杆与第一丝杆的延伸方向相同，第二 支撑组件32b螺纹连接在第二丝杆上，第二驱动电机的驱动端与第二丝杆连接，第二驱动电机用于驱动第二丝杆旋转，从而使得第二支撑组件32b沿第二丝杆移动。
由此，启动第一驱动电机的驱动端转动，驱动第一丝杆转动，第一丝杆带动第一支撑组件32a向靠近或者远离第二支撑组件32b的方向移动，启动第二驱动电机的驱动端转动，驱动第二丝杆转动，第二丝杆带动第二支撑组件32b向靠近或者远离第一支撑组件32a的方向移动，以使得第一支撑组件32a和第二支撑组件32b能够沿使用水平方向相向或者相背移动，且能够第一支撑组件32a和第二支撑组件32b的移动具有较高的精确度，使得第一支撑组件32a和第二支撑组件32b之间的距离能够控制的较为精确。
其中，第一支撑组件32a螺纹连接在第一丝杆上，可在第一支撑组件32a的靠近第一丝杆的一端设置螺纹孔，第一丝杆穿设于螺纹孔中，或者，在第一支撑组件32a的靠近第一丝杆的一端设置螺母，螺母螺接于第一丝杆上，均能够使得第一支撑组件32a较为流畅的沿第一丝杆滑动，且结构简单，易于实现。
在一些实施例中，如图2所示，机架1包括第一安装板12和安装架11，第一安装板12沿竖直方向可移动地设置于安装架11，上热压板2a和辅助压板4均设置于第一安装板12。
由此，上热压板2a和辅助压板4均设置于第一安装板12上，第一安装板12沿竖直方向可移动地设置于安装件上，可通过移动第一安装板12带动上热压板2a和辅助压板4同时移动，简化了上热压板2a和辅助压板4的移动操作，提高了热压机100的热压效率。且第一安装板12沿竖直方向可移动地设置于安装架11上，上热压板2a和辅助压板4均设置于第一安装板12上，可使得上热压板2a和辅助压板4的移动能够较为稳定。
其中，辅助压板4的数量可为两个，两个辅助压板4分别沿第一水平方向设置于上热压板2a的两侧，以在辅助压板4向下挤压辅助上下料模块3下移时，辅助上下料模块3所受到的挤压力能够关于上热压板2a对称，使得辅助上下料模块3的下移不易出现倾斜的情况。
上热压板2a和辅助压板4均设置于第一安装板12上，上热压板2a和辅助压板4可焊接于第一安装板12上，也可以是，上热压板2a和辅助压板4通过螺纹副与第一安装板12螺纹连接。
可选地，如图2所示，机架1还包括第二安装板13，第二安装板13设置于安装架11的第一端且与第一安装板12沿竖直方向相对设置，下热压板2b设置于第二安装板13朝向第一安装板12的一侧。
由此，下热压板2b设置于第二安装板13上，使得下热压板2b的安装能够较为牢固稳定，以使得电芯200在进行热压时不易出现因下热压板2b晃动而降低热压质量的情况。
其中，下热压板2b设置于第二安装板13上，下热压板2b可焊接于第二安装板13上，也可以是，下热压板2b粘接于第二安装板13，还可以是，下热压板2b通过螺栓固定于第二安装板13上，在此并不做限定。
第二安装板13设置于安装架11的连接方式可与下热压板2b与第二安装板13的连接方式大致相同，在此不再进行赘述。
另外，安装架11的第一端可以是安装架11的位于第一安装板12的下方的一端，即第二安装板13可位于第一安装板12的下方。
可选地，如图2所示，机架1还包括下压驱动件15和第三安装板14，第三安装板14设置于安装架11的第二端且位于第一安装板12的背离第二安装板13的一侧，下压驱动件15设置于第三安装板14上，下压驱动件15的驱动端与第 一安装板12连接，下压驱动件15用于驱动第一安装板12移动，以带动上热压板2a和辅助压板4沿竖直方向移动。
由此，可通过下压驱动件15驱动第一安装板12沿竖直方向移动，第一安装板12带动上热压板2a沿竖直方向移动，使得上热压板2a的移动能够方便省力。且，下压驱动件15设置于第三安装板14上，使得下压驱动件15的固定能够较为牢固。
其中，下压驱动件15可以是气缸、电缸、液压缸等中的任一种，在此并不做限定。
另外，第三安装板14设置于安装架11的第二端，第二端可以是安装架11的位于第一安装板12的上方的一端，即第三安装板14可位于第一安装板12的上方。
在一些实施例中，如图6所示，第一支撑组件32a包括支撑杆323和沿第二水平方向(如图6中Y所示的方向)延伸的第一滑轮辊321，第一滑轮辊321可转动地设置于支撑杆323的一端，第一滑轮辊321抵接于承载膜32c的下表面，支撑杆323的另一端与驱动组件31连接，第二水平方向定义为与第一水平方向相垂直的水平方向。
需要解释说明的是，上述的第一滑轮辊321抵接于承载膜32c的下表面是指，承载膜32c绕第一滑轮辊321的上侧设置。
由此，通过第一滑轮辊321抵接于承载膜32c的下表面，可使得第一支撑组件32a在沿第一水平移动时，第一支撑组件32a在支撑承载膜32c的同时，还能够与承载膜32c之间的接触面积较小，降低了第一支撑组件32a和承载膜32c之间的摩擦阻力，使得第一支撑组件32a在沿第一水平方向移动能够较为流畅。第一滑轮辊321可转动地连接于支撑杆323，可使得第一支撑组件32a与承 载膜32c之间的摩擦阻力为滚动摩擦阻力，进一步降低了第一支撑组件32a和承载膜32c之间的摩擦阻力，使得第一支撑组件32a沿第一水平方向的移动能够更为流畅。
其中，支撑杆323的数量可为一个，一个支撑杆323设置于下热压板2b的沿第二水平方向的任一侧，节省材料；也可以是，支撑杆323的数量为两个，两个支撑杆323分别设置于下热压板2b沿第二水平方向的两侧，可使得第一滑轮辊321的连接具有较好的稳固性。
可选地，如图6所示，第一支撑组件32a还包括沿第二水平方向延伸的第二滑轮辊322，第二滑轮辊322可转动地设置于支撑杆323，第二滑轮辊322被配置为在高度方向上低于第一滑轮辊321，承载膜32c依次绕经第二滑轮辊322的下侧和第一滑轮辊321的上侧。
由此，通过第二滑轮辊322被配置为在高度方向上低于第一滑轮辊321，承载膜32c依次绕经第二滑轮辊322的下侧和第一滑轮辊321的上侧，使得第二滑轮辊322能够对承载膜32c起到较好的张紧效果，以使承载膜32c在承载电芯200时不易出现电芯200下沉太多的情况。
承载膜32c依次绕经第二滑轮辊322的下侧，可使得第二滑轮辊322抵接于承载膜32c的上表面，使得承载膜32c与第二滑轮辊322之间的接触面积也较小，减小了承载膜32c与第一支撑组件32a之间的摩擦阻力。第二滑轮辊322可转动地设置于支撑杆323，可使得承载膜32c与第二滑轮辊322之间为滚动摩擦，进一步减小承载膜32c与第一支撑组件32a之间的摩擦阻力，使得第一支撑组件32a的移动更为流畅。
其中，第二滑轮辊322与第一滑轮辊321的结构可相同，以使得第一滑轮辊321与第二滑轮辊322之间能够互换，简化了第一支撑组件32a的组装难度。
上述的第二支撑组件32b的结构可与第一支撑组件32a的大致相同，具体可参考上述对第一支撑组件32a的描述，在此不再进行赘述。
