本申请实施例提供的结合机构10，用于将外观相同的第一电芯21和第二电芯22结合实现两者的合芯。其中，各个电芯20均具有沿第一方向a相对设置的第一端面和第二端面、以及连接第一端面和第二端面的侧面。合芯是指将第一电芯21的第一端面与第二电芯22的第一端面相互贴合，并使第一电芯21的侧面和第二电芯22的侧面对齐。其中，各个电芯20的侧面沿一延伸方向延伸并首尾连接，第一电芯21的侧面和第二电芯22的侧面对齐，是指第一电芯21侧面与第二电芯22侧面在该延伸方向上的各处一一对应对齐。其中，各个电芯20侧面的延伸方向可以呈圆形、正方形、长方形或者多边形等。可以理解地，电芯20的侧面自电芯20第一端面的边缘各处延伸至电芯20第二端面的边缘各处，以连接第一端面和第二端面。
请参阅图1、图2和图3，本申请一实施例中提供了一种结合机构10，包括合芯平台11及多个规正件12。合芯平台11具有用于依次承接第一电芯21和第二电芯22的承接面，第一电芯21的第一端面背离承接面，第二电芯22的第一端面朝向承接面，第一电芯21的第二端面支撑于承接面，第二电芯22的第一端面置于第一电芯21的第一端面。多个规正件12围绕合芯平台11布置，多个规正件12能够通过第一电芯21的侧面定位第一电芯21，并通过第二电芯22的侧面定位第二电芯22，以使得第一电芯21的侧面和第二电芯22的侧面对齐。
上述结合机构10，在实际作业时，第一电芯21和第二电芯22逐个被放置于合芯平台11的承接面上。在合芯平台11接取到第一电芯21时，第一电芯21的第一端面背离承接面，此时将第一电芯21的第二端面放置于承接面上。在合芯平台11接取到第二电芯22时，第二电芯22的第一端面朝向承接面，此时将第二电芯22的第一端面放置于第一电芯21的第一端面上，使得两个电芯20的第一端面贴合。在第一电芯21与第二电芯22贴合后，多个规正件12对第一电芯21和第二电芯22进行定位，以使得第一电芯21的侧面和第二电 芯22的侧面对齐，从而实现两者的合芯。
与现有技术相比，结合机构10将第二电芯22的第一端面叠放于第一电芯21的第一端面后，利用规正件12对合芯后的第一电芯21和第二电芯22的位置进行定位，能够保证合芯后两个电芯的侧面对齐度好，进而保证合芯效果。
具体到实施例中，参见图1、图2和图3，多个规正件12包括两个第一规正件121和两个第二规正件122。两个第一规正件121布置于合芯平台11沿第二方向b相对的两侧，且受控相互靠近或相互远离。两个第二规正件122布置于合芯平台11沿第三方向c相对的两侧，且受控相互靠近或相互远离。在两个第一规正件121相互靠近时，能够抵接第一电芯21沿第二方向b相对的两侧，还能够抵接第二电芯22沿第二方向b相对的两侧。在两个第二规正件122相互靠近时，能够抵接第一电芯21沿第三方向c相对的两侧，还能够抵接第二电芯22沿第三方向c相对的两侧，第一方向a、第二方向b、第三方向c两两垂直。
在实际作业时，多个规正件12在第一电芯21和第二电芯22贴合后，两个第一规正件121相互靠近以对第一电芯21和第二电芯22两者在第二方向b上的两个侧面同时进行位置纠正，两个第二规正件122相互靠近以对第一电芯21和第二电芯22两者在第三方向c上的两个侧面同时进行位置纠正，从而实现对贴合后的两个电芯20进行位置定位，以确保合芯效果好。此时，从四个方向对第一电芯21的侧面和第二电芯22的侧面定位，其定位效果好。
一般地，第一电芯21和第二电芯22两者侧面的延伸方向均呈长方形，即第一电芯21和第二电芯22呈长方体。可选地，第二方向b为第一电芯21和第二电芯22的短边方向，第三方向c为第一电芯21和第二电芯22的长边方向，且第一方向a为第一电芯21和第二电芯22的厚度方向。
可选地，两个第一规正件121中的一者相对合芯平台11固定设置，另一者相对合芯平台11可移动设置。同理，两个第二规正件122中的一者相对合芯平台11固定设置，另一者相对合芯平台11可移动设置。当然，结合机构10还包括用于驱动规正件12移动的驱动件(如气缸)，具体在此不赘述。
其中，规正件12可以为块状、板状或滚轮状构件。
在一些实施例中，参见图4、图5和图6，结合机构10还包括顶盖提取件 14，顶盖提取件14受控在第一位置和第二位置之间移动。当顶盖提取件14位于第一位置时，顶盖提取件14用于提取顶盖30，当顶盖提取件14位于第二位置时，被提取的顶盖30与第一电芯21和第二电芯22装配连接。
在实际作业时，顶盖提取件14移动到第一位置，并提取顶盖30。当第一电芯21与第二电芯22合芯之后，顶盖提取件14移动到第二位置，此时顶盖30与第一电芯21和第二电芯22装配连接。装配连接后的顶盖30、第一电芯21和第二电芯22再通过焊接的方式焊接在一起。
在第一电芯21和第二电芯22合芯后，合芯后的第一电芯21和第二电芯22处于被规正件12定位的状态，此时在规正件12的定位下，顶盖30能够与合芯后的第一电芯21和第二电芯22准确装配。如此，结合机构10不仅能够实现合芯，还能够实现合芯后第一电芯21和第二电芯22与顶盖30准确的装配连接。
其中，顶盖提取件14可以采用夹爪、吸盘等能够提取顶盖30的构件。结合机构10还包括顶盖提取驱动件，顶盖提取驱动件连接并驱动顶盖提取件14朝向合芯平台11移动，以使得顶盖30在移动至与第一电芯21和第二电芯22装配的位置。顶盖提取驱动件可以为气缸、电缸等驱动构件。
优选地，顶盖提取件14受控沿第二方向b移动，当顶盖30沿第二方向b靠近合芯平台11时，顶盖30的面对合芯平台11的一侧能够与第一电芯21和第二电芯22的同一侧连接。此时顶盖提取件14沿直线移动，移动距离短，能够使得结合机构10结构更加紧凑。
其中，各个电芯20均具有一用于与顶盖30配接的配接面，且配接面为电芯20的侧面，合芯后第一电芯21和第二电芯22的配接面位于同一侧且对齐。顶盖30与第一电芯21和第二电芯22装配连接，是指顶盖30与第一电芯21的配接面和第二电芯22的配接面连接。而顶盖30与第一电芯21和第二电芯22的具体装配连接方式根据电芯20具体结构和顶盖30具体结构而定，本申请并不对结合机构10所适应的顶盖30及电芯20的结构作具体限制。
在一示例中，参见图11，顶盖30包括盖板31和凸设于盖板31同一侧的两个侧盖32，且两个侧盖32沿第三方向c相对布置，被顶盖提取件14提取的顶盖30的侧盖32朝向合芯平台11。第一电芯21和第二电芯22均包括凸 设于侧面的正极耳和负极耳。两个侧盖32中的一者用于连接第一电芯21的正极耳和第二电芯22的正极耳，两个侧盖32中的另一者用于连接第一电芯21的负极耳和第二电芯22的负极耳。此时，顶盖30与第一电芯21和第二电芯22装配连接，是指一个侧盖32与两个正极耳连接，另一侧盖32与两个负极耳连接，且盖板31与第一电芯21和第二电芯22的配接面连接。
进一步地，第一电芯21和第二电芯22均具有沿第三方向c相对的第一侧面和第二侧面，各个第一侧面上凸设有正极耳，各个第二侧面上凸设有负极耳，第一电芯21的配接面和第二电芯22的配接面位于第二方向b上且面对盖板31。第一电芯21和第二电芯22合芯后，两个正极耳之间、以及两个负极耳之间的间隔形成插槽，插槽沿第二方向b延伸。在其他实施例中，各个电芯20的各个极耳还可以凸设在配接面上，具体在此不限。
顶盖30与第一电芯21和第二电芯22装配连接时，盖板31抵接第一电芯21的配接面和第二电芯22的配接面，且每一侧盖32插设于对应的插槽内。装配过程是：当顶盖30跟随顶盖提取件14向第二位置移动时，顶盖30两侧的侧盖32逐步插入对应的插槽，直至盖板31与两个配接面相抵为止。
具体到实施例中，顶盖提取件14还被构造为能够移动到第三位置，第三位置位于第一位置和第二位置之间。在合芯平台11接取第一电芯21后，顶盖提取件14从第一位置移动到第三位置，使得顶盖30与第一电芯21预装连接。在合芯平台11接取第二电芯22后，顶盖提取件14从第三位置移动至第二位置，以使得顶盖30与第一电芯21和第二电芯22装配连接。
在实际作业时，参见图11，结合机构10的工作过程是：首先，合芯平台11接取第一电芯21，规正件12对第一电芯21进行定位。然后，顶盖提取件14从第一位置移动到第三位置，使得被提取的顶盖30与第一电芯21预装连接。而后，合芯平台11接取第二电芯22，规正件12对第一电芯21和第二电芯22进行统一定位。最后，顶盖提取件14从第三位置移动到第二位置，使得顶盖30与第一电芯21和第二电芯22装配连接。
此时，顶盖30分两步装配到位，相比一步安装到位，能够避免第一电芯21和第二电芯22上、设置在同一侧的两个极耳因为相互贴近而妨碍侧盖32进入插槽，还能够降低在装配过程中，顶盖30与第一电芯21和第二电芯22 之间的相互磨损。
在一示例中，顶盖30与第一电芯21预装连接时，各个侧盖32的一部分分别与第一电芯21的正极耳和负极耳连接，且顶盖30的盖板31与第一电芯21的配接面之间具有间隔。其中，顶盖30与第一电芯21的具体预装连接方式根据电芯20具体结构和顶盖30具体结构而定，本申请并不对结合机构10所适应的顶盖30及电芯20的结构作具体限制。
具体到实施例中，参见图1、图2和图3，多个规正件12中的至少一个为避让规正件123，避让规正件123与位于第二位置的顶盖提取件14布置于合芯平台11的同一侧，避让规正件123被构造为能够沿第一方向a靠近或远离合芯平台11。在顶盖提取件14朝向第二位置移动时，避让规正件123沿第一方向a远离合芯平台11，以避让顶盖30。
在实际作业时，当顶盖提取件14提取顶盖30朝向第二位置移动时，顶盖提取件14在一与第一方向a垂直的平面内移动。此时，避让规正件123在顶盖提取件14到达第二位置之前沿第一方向a运动至远离合芯平台11，避让规正件123不会与顶盖30发生干涉，使得顶盖30与各个电芯20的配接面能够顺利连接。
可以理解地，避让规正件123在实际作业时是对第一电芯21的配接面和第二电芯22的配接面进行定位。避让规正件123避让顶盖30后，利用顶盖30替代避让规正件123对第一电芯21的配接面和第二电芯22的配接面进行定位。
可选地，避让规正件123与第一避让驱动件和第二避让驱动件连接。第一避让驱动件用于驱动避让规正件123沿第一方向a运动，以避让顶盖30。第二避让驱动件用于驱动避让规正件123沿第二方向b运动，以与第一电芯21的配接面、第二电芯22的配接面相抵，实现配接面的定位。其中，第一避让驱动件和第二避让驱动件均可以为气缸、电缸等驱动构件，具体不作限制。
在一些实施例中，参见图7和图8，结合机构10还包括抵压件13，抵压件13被构造为沿第一方向a靠近或远离合芯平台11。当抵压件13靠近合芯平台11时，能够抵靠于第二电芯22的第二端面，并压紧第一电芯21和第二电芯22。
在实际作业时，在将第一电芯21和第二电芯22合芯后，抵压件13靠近合芯平台11，并抵压于第二电芯22上，使得第二电芯22的第一端面和第二电芯22的第一端面能够紧紧贴合，便于维持第一电芯21和第二电芯22在合芯状态下的稳定性，也便于顶盖30与第一电芯21和第二电芯22装配到位。
其中，抵压件13可以为块状构件、板状构件、滚轮等。可以理解地，结合机构10还包括抵压驱动件，抵压驱动件连接并驱动抵压件13运动。抵压驱动件可以为电缸或气缸等驱动构件，在此不作限制。
具体到实施例中，结合机构10还包括底板111，合芯平台11沿第一方向a弹性连接于底板111。在实际作业时，当抵压件13抵压第二电芯22时，合芯平台11能够起到缓冲作用，避免抵压件13刚性接触第二电芯22而损坏第二电芯22。
优选地，结合机构10还包括导杆112、弹性件113和挡块114。底板111上开设有通孔，导杆112穿设于通孔、并可沿通孔移动。导杆112的一端连接合芯平台11，导杆112的另一端连接挡块114，弹性件113套设于导杆112上，且连接挡块114和底板111，弹性件113用于提供使得合芯平台11远离底板111的作用力。
此时，当抵压件13抵压第二电芯22时，合芯平台11朝向底板111运动并带动导杆112沿通孔移动，使得挡块114远离底板111，弹性件113被拉伸。当抵压件13撤离第二电芯22时，弹性件113恢复，并拉动挡块114靠近底板111，带动合芯平台11远离底板111，从而使得合芯平台11回到初始位置。同时，弹性件113拉伸后产生的作用力能够压紧第二电芯22在抵压件13上。
具体到实施例中，结合机构10还包括平台驱动件，平台驱动件连接合芯平台11，用于驱动合芯平台11在初始位置和下料位置之间移动。当需要合芯时，平台驱动件驱动合芯平台11移动到初始位置，当合芯结束可以下料时，首先取料机构接取合芯平台11上的由第一电芯21、第二电芯22及顶盖30装配连接形成的装配构件，平台驱动件驱动合芯平台11移动到下料位置，此时合芯平台11远离装配构件，便于取料机构取料。
进一步地，平台驱动件驱动合芯平台11沿第一方向a移动，且位于下料位置的合芯平台11相较于位于初始位置的合芯平台11远离抵压件13。如此， 整机结构紧凑。
其中，平台驱动件可以为气缸或电缸。
需要说明地，当合芯平台11弹性连接于底板111时，平台驱动件的驱动端能够随着合芯平台11的移动而回缩一定距离，并不与合芯平台11刚性连接。例如，在平台驱动件为气缸时，连接合芯平台11的活塞杆在抵压件13对合芯平台11施加压力时能够回缩一定距离。
优选地，合芯平台11的承接面上设有内凹的凹槽，凹槽贯通合芯平台11的侧面。凹槽的设置，便于取料机构取料。
在一些实施例中，参见图9和图10，结合机构10还包括翻转组件15，翻转组件15连接于合芯平台11，且被构造为能够驱动合芯平台11绕与第三方向c平行的转轴152转动，合芯平台11在转动时能够在第四位置和第五位置之间移动。当合芯平台11位于第四位置时，用于接取第一电芯21和第二电芯22，以使得第一电芯21和第二电芯22结合，当合芯平台11位于第五位置时，用于供结合后的第一电芯21和第二电芯22下料，第三方向c与第一方向a垂直。
在实际作业时，当合芯平台11转动到第四位置时，用于上料和结合电芯20。当合芯平台11转动到第五位置时，用于下料。如此，用于搬运第一电芯21和第二电芯22至合芯平台11上的搬运机构，与用于取走合芯后的装配构件的取料机构可以设置在不同的位置，且二者的运动路径互不干涉，从而便于取料机构取料，以将装配构件送入下游设备。
优选地，位于第四位置的合芯平台11转动90度后切换到第五位置。
具体到实施例中，翻转组件15包括转轴152和两个侧板151，合芯平台11通过转轴152连接于侧板151上，且合芯平台11位于两个侧板151之间。
进一步地，翻转组件15还包括挡位件154和两个限位件153，挡位件154相对合芯平台11固定设置，两个限位件153固设于侧板151的两个位置。当挡位件154与其中之一的限位件153相抵时，合芯平台11转动到第四位置，当挡位件154与其中至另一的限位件153相抵时，合芯平台11转动到第五位置。
在实际作业时，当合芯平台11运动到各个极限位置时，挡位件154均能 够与限位件153相抵，以限制合芯平台11继续转动，表明合芯平台11已经转动到位。如此，可以防止合芯平台11转动过度，提高合芯平台11的位置精度。
优选地，两个限位件153沿周向间隔设于转轴152上，挡位件154设置侧板151上。挡位件154可以为螺栓，限位件153为限位块。
本申请实施例提供的结合机构10，待合芯平台11上的第二电芯22的第一端面叠设于第一电芯21的第一端面后，利用规正件12对合芯后第一电芯21和第二电芯22的位置进行定位，能够保证合芯后两个电芯的侧面对齐度好，进而保证合芯效果。
另外，本申请一实施例还提供了一种合芯装置，包括搬运机构和上述任一实施例中提供的结合机构10，搬运机构用于将第一电芯21和第二电芯22搬运至合芯平台11。由于该合芯装置包括上述合芯平台11，因此其具备上述实施例中所有有益效果，在此不赘述。
其中，搬运机构可以为机械手等，在此不作限制。搬运机构的搬运过程是先将第一电芯21搬运到承接面，然后将第二电芯22搬运到第一电芯21上。
另外，参见图12，本申请一实施例还提供了一种结合机构10所执行的合芯方法的步骤，合芯方法包括以下步骤：
S1、接取第一电芯21，第一电芯21的第一端面背离合芯平台11的承接面，将第一电芯21的第二端面置于承接面，第一端面和第二端面沿第一方向a相对设置；
S2、接取第二电芯22，第二电芯22的第一端面朝向承接面，将第二电芯22的第一端面置于第一电芯21的第一端面；
S3、将多个规正件12抵接于第一电芯21的侧面以定位第一电芯21，并抵接第二电芯22的侧面以定位第二电芯22，使得第一电芯21的侧面和第二电芯22的侧面对齐，多个规正件12围绕合芯平台11布置，侧面连接第一端面和第二端面。
在本实施例提供中，结合机构10包括合芯平台11和多个规正件12，多个规正件12围绕合芯平台11布置。结合机构10的合芯过程是：合芯平台11先接取第一电芯21，第一电芯21的第一端面背离合芯平台11的承接面，且第一电芯21的第二端面置于承接面上。合芯平台11再接取第二电芯22，且 第二电芯22的第一端面朝向承接面，第二电芯22的第一端面置于第一电芯21的第一端面上。最后，多个规正件12抵接第一电芯21的侧面和第二电芯22的侧面，以定位第一电芯21和第二电芯22，使得第一电芯21和第二电芯22的侧面对齐。
此时，将第二电芯22的第一端面叠放于第一电芯21的第一端面后，利用规正件12对合芯后的第一电芯21和第二电芯22的位置进行定位，能够保证合芯后两个电芯的侧面对齐度好，进而保证合芯效果。
在一实施例中，在将多个规正件12抵接于第一电芯21的侧面以定位第一电芯21，并抵接第二电芯22的侧面以定位第二电芯22，使得第一电芯21的侧面和第二电芯22的侧面对齐的步骤S3之后，还包括：
S4、将提取有顶盖30的顶盖提取件14移动到第二位置，以使得顶盖30与第一电芯21和第二电芯22装配连接。
在本实施例中，结合机构10还包括用于提取顶盖30的顶盖提取件14，顶盖提取件14受控在第一位置和第二位置之间移动。顶盖提取件14在第一位置时，用于提取顶盖30，顶盖提取件14在第二位置时，被提取的顶盖30与合芯后的第一电芯21和第二电芯22装配连接。当执行步骤S3之后，表明第一电芯21和第二电芯22已经合芯。此时，驱动提取有顶盖30的提取件移动到第二位置，以使得顶盖30与合芯后的第一电芯21和第二电芯22装配连接。
在第一电芯21和第二电芯22合芯后，合芯后的第一电芯21和第二电芯22处于被规正件12定位的状态，此时在规正件12的定位下，顶盖30能够与合芯后的第一电芯21和第二电芯22准确装配。如此，不仅能够实现合芯，还能够实现合芯后第一电芯21和第二电芯22与顶盖30准确的装配连接。
可以理解地，在将提取有顶盖30的顶盖提取件14移动到第二位置的步骤之前，还包括将顶盖提取件14移动到第一位置，以提取顶盖30。
其中，各个电芯20均具有一用于与顶盖30配接的配接面，且配接面为电芯20的侧面，合芯后第一电芯21和第二电芯22的配接面位于同一侧且对齐。顶盖30与第一电芯21和第二电芯22装配连接，是指顶盖30与第一电芯21的配接面和第二电芯22的配接面连接。而顶盖30与第一电芯21和第二电芯22的具体装配连接方式根据电芯20具体结构和顶盖30具体结构而定，本申 请并不对结合机构10所适应的顶盖30及电芯20的结构作具体限制。
在一示例中，顶盖30包括盖板31和凸设于盖板31同一侧的两个侧盖32，且两个侧盖32沿第三方向c相对布置，被顶盖提取件14提取的顶盖30的侧盖32朝向合芯平台11。第一电芯21和第二电芯22均包括凸设于侧面的正极耳和负极耳。两个侧盖32中的一者用于连接第一电芯21的正极耳和第二电芯22的正极耳，两个侧盖32中的另一者用于连接第一电芯21的负极耳和第二电芯22的负极耳。此时，顶盖30与第一电芯21和第二电芯22装配连接，是指一个侧盖32与两个正极耳连接，另一侧盖32与两个负极耳连接，且盖板31与第一电芯21和第二电芯22的配接面连接。
进一步地，第一电芯21和第二电芯22均具有沿第三方向c相对的第一侧面和第二侧面，各个第一侧面上凸设有正极耳，各个第二侧面上凸设有负极耳，第一电芯21的配接面和第二电芯22的配接面位于第二方向b上且面对盖板31。第一电芯21和第二电芯22合芯后，两个正极耳之间、以及两个负极耳之间的间隔形成插槽，插槽沿第二方向b延伸。在其他实施例中，各个电芯20的各个极耳还可以凸设在配接面上，具体在此不限。
顶盖30与第一电芯21和第二电芯22装配连接时，盖板31抵接第一电芯21的配接面和第二电芯22的配接面，且每一侧盖32插设于对应的插槽内。装配过程是：当顶盖30跟随顶盖提取件14向第二位置移动时，顶盖30两侧的侧盖32逐步插入对应的插槽，直至盖板31与两个配接面相抵为止。
具体到实施例中，在将第一电芯21的第二端面置于承接面的步骤S1之后，还包括：
S11、将多个规正件12切换到定位状态，以定位第一电芯21，处于定位状态的多个规正件12抵接于位于合芯平台11上的第一电芯21的侧面；
S12、将多个规正件12切换到非定位状态，以松开第一电芯21，处于非定位状态的多个规正件12至少远离位于合芯平台11上的第一电芯21的侧面的相交两侧；
相应地，将多个规正件12抵接于第一电芯21的侧面以定位第一电芯21，并抵接第二电芯22的侧面以定位第二电芯22，使得第一电芯21的侧面和第二电芯22的侧面对齐的步骤S3，包括：
S31、将多个规正件12切换到定位状态，位于定位状态的多个规正件12抵接于与第一电芯21的侧面和第二电芯22的侧面，以使得第一电芯21的侧面和第二电芯22的侧面对齐。
在本实施例中，多个规正件12能够在定位状态和非定位状态之间切换，当多个规正件12处于定位状态时，多个规正件12能够对位于合芯平台11上的第一电芯21的侧面、位于合芯平台11上的第二电芯22的侧面进行定位。当多个规正件12处于非定位状态时，多个规正件12能够松开位于合芯平台11上的第一电芯21、位于合芯平台11上的第二电芯22。
在合芯平台11接取第一电芯21之后，多个规正件12切换到定位状态，对第一电芯21进行定位。然后，多个规正件12切换到非定位状态，松开第一电芯21，便于后续第二电芯22的放置。而后，合芯平台11接取第二电芯22，且第二电芯22被放置于第一电芯21上。最后，多个规正件12切换到定位状态，对第一电芯21和第二电芯22进行统一定位。
此时，在接取第一电芯21后对第一电芯21进行定位，有助于加快后续统一定位的速度。
具体到实施例中，在将多个规正件12切换到定位状态，以定位第一电芯21的步骤S11之后，还包括：
S111、将提取有顶盖30的顶盖提取件14移动到第三位置，以使得顶盖30与第一电芯21预装连接，第三位置相较于第二位置远离合芯平台11；
相应地，将提取有顶盖30的顶盖提取件14沿第二方向b移动到第二位置，以使得顶盖30与第一电芯21和第二电芯22装配连接的步骤S4，包括：
S41、将顶盖提取件14从第三位置移动到第二位置，以使得顶盖30与第一电芯21和第二电芯22装配连接。
在本实施例中，顶盖提取件14还被构造为能够移动到第三位置，第三位置位于第一位置和第二位置之间。在合芯平台11接取第一电芯21后，顶盖提取件14从第一位置移动到第三位置，使得顶盖30与第一电芯21预装连接。在合芯平台11接取第二电芯22后，顶盖提取件14从第三位置移动至第二位置，以使得顶盖30与第一电芯21和第二电芯22装配连接。
在合芯平台11接取电芯20之前，多个规正件12处于非定位状态。当合 芯平台11接取到第一电芯21后，多个规正件12由非定位状态切换到定位状态，并对第一电芯21进行定位。然后，多个规正件12由定位状态切换到非定位状态，以松开第一电芯21。此后，将顶盖提取件14从第一位置移动到第三位置，将顶盖30与第一电芯21预装连接。而后，合芯平台11接取第二电芯22，并将第二电芯22放置于第一电芯21上。紧接着，多个规正件12由非定位状态切换到定位状态，对第一电芯21和第二电芯22进行定位。最后，顶盖提取件14从第三位置运动到第二位置，将顶盖30与第一电芯21和第二电芯22装配连接到位。
此时，顶盖30分两步装配到位，相比一步安装到位，能够避免第一电芯21和第二电芯22上、设置在同一侧的两个极耳因为相互贴近而妨碍侧盖32进入插槽，还能够降低在装配过程中，顶盖30与第一电芯21和第二电芯22之间的相互磨损。
在一示例中，顶盖30与第一电芯21预装连接时，各个侧盖32的一部分分别与第一电芯21的正极耳和负极耳连接，且顶盖30的盖板31与第一电芯21的配接面之间具有间隔。其中，顶盖30与第一电芯21的具体预装连接方式根据电芯20具体结构和顶盖30具体结构而定，本申请并不对结合机构10所适应的顶盖30及电芯20的结构作具体限制。
可以理解地，在将提取有顶盖30的顶盖提取件14移动到第三位置的步骤之前，还包括：将顶盖提取件14移动至第一位置，并提取顶盖30，在顶盖提取件14的移动路径上，第三位置位于第一位置和第二位置之间。如此，能够使得顶盖提取件14提取顶盖30。
具体到实施例中，在步骤S3和步骤S4之间，还包括:
S5、将避让规正件123远离合芯平台11。
在本实施例中，多个规正件12中的至少一个为避让规正件123，避让规正件123与位于第二位置的顶盖提取件14布置于合芯平台11的同一侧，避让规正件123被构造为能够沿第一方向a靠近或远离合芯平台11。在顶盖提取件14朝向第二位置移动时，避让规正件123沿第一方向a远离合芯平台11，以避让顶盖30。
在实际作业时，当顶盖提取件14提取顶盖30朝向第二位置移动时，顶盖 提取件14在一与第一方向a垂直的平面内移动。此时，避让规正件123在顶盖提取件14到达第二位置之前沿第一方向a运动至远离合芯平台11，避让规正件123不会与顶盖30发生干涉，使得顶盖30与各个电芯20的配接面能够顺利连接。
可以理解地，避让规正件123在实际作业时是对第一电芯21的配接面和第二电芯22的配接面进行定位。避让规正件123避让顶盖30后，利用顶盖30替代避让规正件123对第一电芯21的配接面和第二电芯22的配接面进行定位。
具体到实施例中，在步骤S4之后，还包括：
S6、控制抵压件13抵压第二电芯22。
在本实施例中，结合机构10还包括抵压件13，抵压件13被构造为沿第一方向a靠近或远离合芯平台11。当抵压件13靠近合芯平台11时，能够抵靠于第二电芯22的第二端面，并压紧第一电芯21和第二电芯22。
在实际作业时，在将第一电芯21和第二电芯22合芯后，抵压件13靠近合芯平台11，并抵压于第二电芯22上，使得第二电芯22的第一端面和第二电芯22的第一端面能够紧紧贴合，便于维持第一电芯21和第二电芯22在合芯状态下的稳定性，也便于顶盖30与合芯后的第一电芯21和第二电芯22装配到位。
本申请实施例提供的合芯方法，将第二电芯22的第一端面叠放于第一电芯21的第一端面后，利用规正件12对第一电芯21和第二电芯22的位置进行定位，能够保证合芯后两个电芯的侧面对齐度好，进而保证合芯效果。
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申请专利范围的限制。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。
