Description

一种排版叠焊机 技术领域
本发明涉及电池生产领域，具体地说是一种排版叠焊机。
 背景技术
光伏组件通常由上、下层玻璃板和位于上、下层玻璃板之间的电池串阵列经封装制成。光伏组件制作时，需要将串焊机生产出来的电池串按照电池串阵列的要求进行排版，并在电池串的留长焊带上叠焊汇流条。目前，电池串在排版和叠焊汇流条的过程中，需要经历多次的抓放。例如，在排版时，需要抓手将电池串抓放到定位台上进行排版，再将排版后的全部电池串抓放到玻璃板上输出。在叠焊汇流条时，需要抓手将玻璃板上的全部电池串抓放到规整台进行规整，再将规整后的全部电池串从规整台抓走进行汇流条焊接，并在焊接完成后放回玻璃板上。上述排版和叠焊过程中，电池串共经历了多达四次抓放，而电池串的频繁抓放是造成电池片碎片的主要原因，因此减少排版叠焊过程中电池串的抓放次数尤为重要。
 发明内容
为了解决上述技术问题，本发明提供了一种排版叠焊机，其详细技术方案如下：
一种排版叠焊机，用于根据光伏组件中电池串阵列对电池串进行排版和汇流条焊接，排版叠焊机包括排版拾取部、规整输送部、叠焊拾取部和叠焊部，其中：
排版拾取部设置在规整输送部的前道，排版拾取部用于拾取电池串并将电池串按照排版正负极要求摆放至规整输送部上；
规整输送部用于承接并规整排版拾取部摆放的电池串；
叠焊拾取部包括与电池串阵列中的各个电池串一一对应排布的拾串组件；规整输送部还用于按照排版位置要求将规整的电池串输送至拾串工位，叠焊拾取部移动以带动与拾串工位处的电池串对应的拾串组件移动至拾串工位拾取电池串；
叠焊拾取部移动以将拾取有电池串的拾串组件带动至焊接工位，叠焊部向位于焊接工位的电池串端部的留长焊带上焊接汇流条；
叠焊拾取部还用于在各个拾串组件所拾取的电池串均完成汇流条焊接后，移动以将各个拾串组件所拾取的电池串铺放于玻璃板上。
本发明提供的排版叠焊机，由排版拾取部按照排版正负极要求先将电池串摆放至规整输送部上，规整输送部再按照排版的位置要求规整好电池串并将规整好的电池串输送至拾串工位，叠焊拾取部从拾串工位拾取电池串后将电池串输送至焊接工位，叠焊部直接将汇流条焊接至叠焊拾取部上的电池串上，汇流条全部焊接完成后叠焊拾取部再将全部电池串铺放至玻璃板上，至此完成一个电池串阵列的排版及汇流条焊接。
可见，本发明提供的排版叠焊机，整个排版叠焊过程中电池串仅被抓放两次，分别为排版拾取部的一次抓放和叠焊拾取部的一次抓放，大大地减少了电池串的抓放次数，可有效降低排版叠焊过程中电池片的碎片率。
在一些实施例中，排版拾取部每隔预定时间向规整输送部上摆放至少一个组件单元，每个组件单元包括两个沿电池串长度方向并列布置的电池串，多个组件单元沿电池串宽度方向并排布置组成电池串阵列；规整输送部每隔预定时间将规整完成的组件单元输送至拾串工位；叠焊拾取部每隔预定时间向后道方向移动预定距离，以将与拾串工位处的组件单元对应的拾串组件带动至拾串工位拾取组件单元，同时将已拾取有组件单元的拾串组件带动至焊接工位。
本实施例通过将一个完整的电池串阵列划分成若干个组件单元，并以至少一个组件单元为单位进行排版拾取、规整输送、叠焊拾取和焊接汇流条，即排版拾取部每次按照组件单元来向规整输送部上摆放电池串；相应的，规整输送部每次将规整后的组件单元输送至拾串工位处；叠焊拾取部每次向后道方向移动预定距离，以将与拾串工位处的组件单元对应的拾串组件带动至拾串工位以拾取当前位于拾串工位处的组件单元，以及将在此之前已拾取有组件单元的拾串组件带动至焊接工位处，叠焊部每次向焊接工位处的组件单元上焊接汇流条，如此循环，直至在叠焊拾取部上完成一个电池串阵列的拾取和汇流条焊接，即可将该电池串阵列下料至玻璃板上。
可见，规整输送部每次规整输送至少一个组件单元，而不是等电池串阵列中的所有组件单元全部规整好后再进行输送；叠焊部每次焊接输送到位的至少一个组件单元，而不是等待所有组件单元到位后再实施焊接，从而本实施例可以简化规整输送部、叠焊部的结构，降低设备成本，减少设备占地面积，且能提升排版和汇流条焊接效率。

 实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
本发明是一种排版叠焊机，其用于根据光伏组件中电池串阵列对电池串进行排版和汇流条焊接，且在整个排版叠焊过程中，电池串仅被拾取两次，从而有效降低碎片率。
如图1至图3所示，本发明提供的是一种排版叠焊机，用于根据光伏组件中电池串阵列对电池串进行排版和汇流条焊接，该排版叠焊机包括排版拾取部、规整输送部、叠焊拾取部10和叠焊部11，其中：
排版拾取部设置在规整输送部的前道，排版拾取部用于拾取电池串并将电池串按照排版正负极要求摆放至规整输送部上。
规整输送部用于承接并规整排版拾取部摆放的电池串。
叠焊拾取部10包括与电池串阵列中的各个电池串一一对应排布的拾串组件1001。规整输送部还用于按照排版位置要求将规整的电池串输送至拾串工位，叠焊拾取部10移动以带动与拾串工位处的电池串对应的拾串组件1001移动至拾串工位拾取电池串。
叠焊拾取部10移动以将拾取有电池串的拾串组件1001带动至焊接工位，叠焊部向位于焊接工位的电池串端部的留长焊带上焊接汇流条。
叠焊拾取部还用于在各个拾串组件1001所拾取的电池串均完成汇流条焊接后，移动以将各个拾串组件1001所拾取的电池串铺放于玻璃板13上。
可见，采用本发明的排版叠焊机，由排版拾取部按照排版正负极要求先将电池串摆放至规整输送部上，规整输送部再按照排版的位置要求规整好电池串并将电池串输送至拾串工位，叠焊拾取部从拾串工位拾取电池串后将电池串输送至焊接工位，接着，叠焊部直接将汇流条焊接至保持在叠焊拾取部上的电池串的端部的留长焊带上。由于叠焊拾取部上的拾串组件与电池串阵列中的电池串一一对应排布，故在所有拾串组件均完成对电池串的拾取后，即完成了电池串的排版，最后，叠焊拾取部在所拾取的电池串全部焊接完汇流条后将电池串铺放于玻璃板上，即完成一个光伏组件的排版和汇流条焊接。
整个排版叠焊过程中电池串仅被抓放两次，其大幅度地减少了电池串的抓放次数，可有效降低排版叠焊过程中电池片的碎片率。
光伏组件通常可以分为整片组件和半片组件，整片组件由多个整片电池串所组成的电池串阵列经封装后制成，半片组件由多个半片电池串所组成的电池串阵列经封装后制成，半片电池串是由整片电池片掰断后的小片串焊而成，半片电池串大约为整片电池串长度的一半。半片电池串和整片电池串的端部都存在有留长焊带，用于与汇流条焊接，汇流条能够将各电池串产生的电流汇集起来并通过接线盒输出。
通常，从组件整体设计长度上考虑，整片组件中的电池串阵列只有一组整片电池串，一组整片电池串中的各个电池串并排布置，从而整片组件中的留长焊带只位于组件的首部和尾部。而为了获得与整片组件相当的长度，半片组件中的电池串阵列包括两组半片电池串，两组半片电池串沿电池串长度方向并列布置，每组半片电池串中的各个电池串并排布置，从而半片组件中的留长焊带位于组件的首部、中部和尾部。
与整片组件相比，半片组件表现出更为优秀的光电转换效率，因此近年来备受关注和青睐。
针对上述半片组件的排版和汇流条焊接，本发明的一种实施方式为，排版拾取部每隔预定时间向规整输送部上摆放至少一个组件单元，每个组件单元包括两个沿电池串长度方向并列布置的电池串，多个组件单元沿电池串宽度方向并排布置组成电池串阵列；规整输送部每隔预定时间将规整完成的组件单元输送至拾串工位；叠焊拾取部每隔预定时间向后道方向移动预定距离，以将与拾串工位处的组件单元对应的拾串组件带动至拾串工位拾取组件单元，同时将已拾取有组件单元的拾串组件带动至焊接工位。
通过将半片组件的电池串阵列划分成若干个组件单元，并以至少一个组件单元为单位进行排版拾取、规整输送、叠焊拾取和焊接汇流条，即排版拾取部每次按照组件单元来向规整输送部上摆放电池串；相应的，规整输送部每次将规整后的组件单元输送至拾串工位处；叠焊拾取部每次向后道方向移动预定距离，以将与拾串工位处的组件单元对应的拾串组件带动至拾串工位以拾取当前位于拾串工位处的组件单元，以及将在此之前已拾取有组件单元的拾串组件带动至焊接工位处，叠焊部每次向焊接工位处的组件单元上焊接汇流条，如此循环，直至在叠焊拾取部上完成一个电池串阵列的拾取和汇流条焊接，即可将该电池串阵列下料至玻璃板上。
通过以组件单元为单位进行排版拾取、规整输送、叠焊拾取和焊接汇流条，从而规整输送部无需等电池串阵列中的所有组件单元全部规整好后再进行输送；叠焊部无需等待所有组件单元到位后再实施焊接，一方面可以简化规整输送部、叠焊部的结构，即规整输送部和叠焊部只需要针对待输送的组件单元进行设置，无需针对全部的组件单元进行设置，从而可以大大降低设备成本，减少设备占地面积，且能提升排版和汇流条焊接效率。
下面以图9所示的半片组件的电池串阵列为例，对本实施例中以组件单元为单位进行排版和叠焊的过程进行说明。
图9中的电池串阵列由6个组件单元沿电池串的宽度方向（如图中的Y轴方向）并排排布形成，每个组件单元包括两个沿电池串的长度方向（如图中的X轴方向）并列排布的电池串。具体的，第一个组件单元由第一电池串101和第二电池串102排布而成，第二个组件单元由第三电池串103和第四电池串104排布而成，第三个组件单元由第五电池串105和第六电池串106排布而成，第四个组件单元由第七电池串107和第八电池串108排布而成，第五个组件单元由第九电池串109和第十电池串110排布而成，第六个组件单元由第十一电池串111和第十二电池串112排布而成。
相应的，叠焊拾取部10包括与图9所示电池串阵列中的12个电池串一一对应排布的12个拾串组件1001，相互并列的两个拾串组件1001构成一个拾取单元，每个拾取单元均用于对应拾取一个组件单元。
以排版拾取部每隔预定时间向规整输送部上摆放一个组件单元，规整输送部每隔预定时间将规整完成的一个组件单元输送至拾串工位，叠焊拾取部每隔预定时间向后道方向移动预定距离，以将与拾串工位处的一个组件单元对应的一个拾取单元带动至拾串工位拾取该组件单元，同时将已拾取有一个组件单元的拾取单元带动至焊接工位，叠焊部向焊接工位的组件单元焊接汇流条为例进行说明。具体的，排版拾取部、规整输送部、叠焊拾取部和叠焊部的配合工作过程如下：
初始状态下，叠焊拾取部10的第一个拾取单元位于拾串工位，排版拾取部向规整输送部上摆放第一个组件单元，即第一电池串101和第二电池串102，规整输送部对第一电池串101和第二电池串102进行规整后将第一个组件单元输送至拾串工位，叠焊拾取部10的第一个拾取单元拾取规整输送部输送的第一电池串101和第二电池串102，接着，叠焊拾取部10向后道方向移动预定距离，使得第一个拾取单元移动至焊接工位，第二个拾取单元移动至拾串工位，然后叠焊部向位于焊接工位处的第一电池串101和第二电池串102的留长焊带上焊接第一中间汇流条201。
在第一个组件单元被叠焊拾取部10拾取后，规整输送部随即返回以接收排版拾取部拾取的第二个组件单元，即第三电池串103和第四电池串104，规整后将第三电池串103和第四电池串104输送至拾串工位，叠焊拾取部的第二个拾取单元拾取第三电池串103和第四电池串104，然后叠焊拾取部10向后道方向移动预定距离，使得第二个拾取单元移动至焊接工位，第三个拾取单元移动至拾串工位，然后叠焊部对位于焊接工位处的第一电池串101、第二电池串102、第三电池串103和第四电池串104的留长焊带上焊接第一首部汇流条202、第一尾部汇流条203。
在第二个组件单元被叠焊拾取部10拾取后，规整输送部随即返回以接收排版拾取部拾取的第三个组件单元，即第五电池串105和第六电池串106，规整后将第五电池串105和第六电池串106输送至拾串工位，叠焊拾取部的第三个拾取单元拾取第五电池串105和第六电池串106，然后叠焊拾取部10向后道方向移动预定距离，使得第三个拾取单元移动至焊接工位，第四个拾取单元移动至拾串工位，然后叠焊部对位于焊接工位处的第三电池串103、第四电池串104、第五电池串105和第六电池串106的留长焊带上焊接第二中间汇流条204。
在第三个组件单元被叠焊拾取部10拾取后，规整输送部随即返回以接收排版拾取部拾取的第四个组件单元，即第七电池串107和第八电池串108，规整后将第七电池串107和第八电池串108输送至拾串工位，叠焊拾取部的第四个拾取单元拾取第七电池串107和第八电池串108，然后叠焊拾取部10向后道方向移动预定距离，使得第四个拾取单元移动至焊接工位，第五个拾取单元移动至拾串工位，然后叠焊部对位于焊接工位处的第五电池串105、第六电池串106、第七电池串107和第八电池串108的留长焊带上焊接第二首部汇流条205、第二尾部汇流条206。
在第四个组件单元被叠焊拾取部10拾取后，规整输送部随即返回以接收排版拾取部拾取的第五个组件单元，即第九电池串109和第十电池串110，规整后将第九电池串109和第十电池串110输送至拾串工位，叠焊拾取部的第五个拾取单元拾取第九电池串109和第十电池串110，然后叠焊拾取部10向后道方向移动预定距离，使得第五个拾取单元移动至焊接工位，第六个拾取单元移动至拾串工位，然后叠焊部对位于焊接工位处的第七电池串107、第八电池串108、第九电池串109和第十电池串110的留长焊带上焊接第三中间汇流条207。
在第五个组件单元被叠焊拾取部10拾取后，规整输送部随即返回以接收排版拾取部拾取的第六个组件单元，即第十一电池串111和第十二电池串112，规整后将第十一电池串111和第十二电池串112输送至拾串工位，叠焊拾取部的第六个拾取单元拾取第十一电池串111和第十二电池串112，然后叠焊拾取部10向后道方向移动预定距离，使得第六个拾取单元移动至焊接工位，然后叠焊部对位于焊接工位处的第九电池串109、第十电池串110、第十一电池串111和第十二电池串112的留长焊带上焊接第三首部汇流条208、第四中间汇流条209及第三尾部汇流条210。
至此，完成对一个半片组件的电池串阵列的排版和汇流条焊接，叠焊拾取部随后将焊接完汇流条的电池串阵列下料至玻璃板上。
为了进一步提升效率，排版拾取部每次也可以向规整输送部上摆放4个、6个等其他数量的电池串，以形成2个、3个等其他对应数量的组件单元，对应的，规整输送部每次向拾串工位输送对应数量的组件单元，叠焊拾取部10每次移动将相应数量的拾取单元移动至拾串工位及焊接工位。如，排版拾取部每次向规整输送部上摆放4个电池串，即两个组件单元，此时，规整输送部每次将两个组件单元输送至拾串工位，叠焊拾取部每次移动时，将两个拾取单元移动至焊接工位的同时也将相邻的两个拾取单元移动至拾串工位。
当然，本发明的排版叠焊机同样适用对整片电池串的排版及叠焊。该情形下，在一些实现方式中，排版拾取部每次向规整输送部上摆放一个电池串，规整输送部完成对一个电池串的规整后，将该电池串输送至拾串工位并提供给叠焊拾取部上与该电池串相对应的拾串组件；该拾串组件拾取电池串后移动至焊接工位，同时后面相邻的一个拾串组件移动至拾串工位，叠焊部对焊接工位的电池串焊接汇流条。整片组件的排版叠焊过程与上述半片组件相似，在此不做详细说明。
在一些实现方式中，叠焊拾取部10还包括步进驱动机构和第一安装支架，其中：第一安装支架连接在步进驱动机构的移动端上，各拾串组件1001共同安装在第一安装支架上。步进驱动机构用于步进驱动各拾串组件1001平移，以将与拾串工位处的组件单元对应的拾串组件1001带动至拾串工位拾取组件单元，同时将已拾取有组件单元的拾串组件1001带动至焊接工位。
在一些实现方式中，排版拾取部包括移动机构、旋转机构及拾取组件，其中：旋转机构连接在移动机构的驱动端上，拾取组件安装在旋转机构上；移动机构用于驱动拾取组件平移及升降以拾取电池串；旋转机构用于驱动拾取组件转动，以将电池串转动至符合排版正负极要求；移动机构还用于驱动拾取组件平移及升降以将拾取的电池串摆放至规整输送部上。
移动机构可以为机械人手臂或能够在X、Y、Z三个方向移动的桁架。拾取组件可以采用能够吸附电池串的吸盘组。
电池串在排版的时候要保证排布到一起的并排相邻的两个电池串的相同一端极性相反，以便于汇流条的串联焊接，因此设置了旋转机构，从而控制拾取的部分电池串在平面内转动，以保证最终并排布置的相邻两个电池串相同的一端极性相反，从而符合排版的正负极要求。
如图1至图3所示，在一些实现方式中，排版拾取部设置为两个，分别为第一排版拾取部6和第二排版拾取部7，其中：第一排版拾取部6用于向规整输送部上摆放组件单元中的其中一个电池串，第二排版拾取部7用于向规整输送部上摆放组件单元中的另一个电池串。即，在实施对半片电池串的排版和汇流条焊接时，第一排版拾取部6和第二排版拾取部7同步地将组件单元中的两个电池串摆放至规整输送部上，从而提升组件单元的排版效率。
在一些实现方式中，如图1和图4所示，规整输送部包括结构相同的第一规整输送机构8和第二规整输送机构9，第一规整输送机构8和第二规整输送机构9沿第一水平方向（如图1中的X方向）并列布置。第一规整输送机构8和第二规整输送机构9分别用于承载组件单元中的两个电池串。
第一规整输送机构8包括第一平移驱动机构81以及连接在第一平移驱动机构81的移动端上的至少一个规整平台82，图4中第一平移驱动机构81的移动端上连接有一个规整平台82，规整平台82用于承载一串电池串并规整电池串，当第一平移驱动机构81的移动端上连接有多个规整平台82时，每个规整平台82均用于承载一串电池串并规整电池串。第一平移驱动机构81用于驱动各规整平台82沿滑轨811平移，滑轨811沿与第一水平方向垂直的第二水平方向（如图4中的Y轴方向）布置，以将承载于各规整平台82上的电池串输送至拾串工位。
如前文所描述的，在实施对半片电池串的排版和汇流条焊接时，如排版拾取部每次向规整输送部上摆放一个组件单元，则第一规整输送机构8、第二规整输送机构9分别设置一个规整平台82即可。其中，第一规整输送机构8的规整平台82用于摆放组件单元中的一个电池串，第二规整输送机构9的规整平台82用于摆放组件单元中的另一个电池串。若排版拾取部每次向规整输送部上摆放N个组件单元，N大于1，则第一规整输送机构8、第二规整输送机构9分别设置N个规整平台82。
在一些实现方式中，由第一排版拾取部6将组件单元中的一个电池串摆放至第一规整输送机构8的规整平台82上，由第二排版拾取部7将组件单元中的另一个电池串摆放至第二规整输送机构9的规整平台82上。
继续参考图4所示，在一些实现方式中，规整平台82包括第二平移驱动机构821、升降驱动机构822、旋转驱动机构823及规整承载板824，其中：第二平移驱动机构821连接在第一平移驱动机构81的移动端上，升降驱动机构822连接在第二平移驱动机构821的移动端上，旋转驱动机构823连接在升降驱动机构822的移动端上，规整承载板824连接在旋转驱动机构823的移动端上。规整承载板824用于承载电池串，第二平移驱动机构821用于驱动规整承载板824沿第一水平方向（图中的X方向）平移，升降驱动机构822用于驱动规整承载板824升降，旋转驱动机构823则用于驱动规整承载板824在水平面内旋转。
通过第一平移驱动机构81、第二平移驱动机构821和旋转驱动机构823的配合驱动，可带动规整承载板824实现在X、Y方向的平移及水平方向的旋转，从而实现对摆放于规整承载板824上的电池串的位置规整，以及实现将规整后的电池串按照排版位置要求输送至拾串工位。升降驱动机构822能够在规整平台移动到拾串工位后驱动规整承载板824上升，以将电池串传递给叠焊拾取部上相应的拾串组件。
在一些实现方式中，第一排版拾取部6拾取一串电池串，根据排版正负极要求将电池串旋转后放到第一规整输送机构8的规整平台82上，同步的，第二排版拾取部7拾取另一串电池串，根据排版正负极要求将电池串旋转后放到第二规整输送机构9的规整平台82上。第一规整输送机构8和第二规整输送机构9分别规整对应的电池串后，同步的将两个电池串向后道输送，一直输送到拾串工位的预定位置。
在一些实现方式中，第一规整输送机构8、第二规整输送机构9的上方设置有视觉相机，视觉相机用于对电池串拍照以获取电池串的位置信息，第一规整输送机构8、第二规整输送机构9根据视觉相机获取到的对应电池串的位置信息实施对对应电池串的规整和输送。
在一些实现方式中，本发明的排版叠焊机还包括电池串供料部，电池串供料部用于生产电池串并将所生产的电池串提供给排版拾取部。
继续参考图1至图3所示，在一些实现方式中，电池串供料部包括串焊机1、出料输送线2、翻转机构3及缓存机构4，其中：串焊机1用于生产电池串。出料输送线2用于输出串焊机1生产的电池串。缓存机构4设置在出料输送线2的边侧，翻转机构3用于从出料输送线2上拾取电池串，并将拾取的电池串翻转180°后放置至缓存机构4上。排版拾取部从缓存机构4上拾取电池串。
在一些实现方式中，继续参考图1至图3，串焊机1为双线串焊机，具有两条电池串生产线，相应的，两条电池串生产线的出料端分别对应设置有一条出料输送线2以输出电池串，其中一个出料输送线2输出的电池串提供给第一排版拾取部6，另一个出料输送线2输出的电池串提供给第二排版拾取部7。通过采用双线串焊机实现了电池串的双供料，提升了电池串的供料效率。在设置两条出料输送线2时，相应的，翻转机构3和缓存机构4也均设置为两个。两个翻转机构3分别从对应的出料输送线2上拾取电池串，并将拾取的电池串缓存至对应的缓存机构4内。
通常，串焊机生产的电池串为正面朝上，排版时要求电池串背面朝上，通过设置翻转机构3，可以实现对电池串的180度翻转，从而将电池串直接翻转到待排版的状态，提升了后道排版拾取部的拾取效率。而通过设置缓存机构4，则实现了对串焊机1生产的电池串的缓存，避免串焊机1生产速度与后道的排版拾取速度不一致而导致的排版等待，对于双线串焊机，缓存机构的设置还能避免因两条生产线生产速度不一致而导致的排版等待。此外，翻转机构能够将电池串拾起翻转后直接放置到缓存机构上，无需额外的电池串抓手来拾取翻转后的电池串再放到缓存机构，通过一次抓放即实现对电池串的翻转和缓存，有利于降低电池片的碎片率。
在一些实现方式中，如图5和图6所示，翻转机构3包括第一升降驱动模组31、第二升降驱动模组32、翻转电机33及翻转吸附组件34，其中：翻转电机33连接在第二升降驱动模组32的驱动端上，翻转吸附组34的第一端连接在第一升降驱动模组31的驱动端上，翻转吸附组件34的第二端连接在翻转电机33的驱动端上。第一升降驱动模组31和第二升降驱动模组32配合驱动翻转吸附组件34升降，翻转电机33用于驱动翻转吸附组件34在出料输送线2和缓存机构4之间翻转，以带动翻转吸附组件34从出料输送线2上吸取电池串，并将吸取的电池串翻转至缓存机构4上。
可见，通过第一升降驱动模组31、第二升降驱动模组32、翻转电机33及翻转吸附组件34的配合，翻转机构3能够从出料输送线2拾取电池串，并将电池串翻转180度后缓存至缓存机构4内。
继续参考图5和图6所示，在一些实现方式中，缓存机构4包括第二安装支架41、若干托板42、第一托板推送机构43及第二托板推送机构44，其中：若干托板42沿竖直方向叠装在第二安装支架41上，各托板42均经滑轨连接在第二安装支架41上。第一托推送机构43被配置为每次将一个托板42向第一侧推送出第二安装支架41，以接收翻转机构3转运的电池串。第二托板推送机构44则被配置为每次将一个承载有电池串的托板42向第二侧推送出第二安装支架41，以将电池串42提供给排版拾取部。
通过设置多个托板42，缓存机构4可以实现对多个电池串的缓存。而将托板42设置成可以从第二安装支架41的两侧伸出或收回，托板42向第一侧伸出时，接收翻转机构3转运的电池串，托板42向第二侧伸出时，则将电池串提供给排版拾取部，从而实现了电池串存入和取出从两侧进行，互不干扰。
如图5所示，可选的，托板42上设置有供翻转吸附组件34穿过的避让槽421。完成对电池串的翻转后，翻转吸附组件34即位于电池串的下方，在翻转吸附组件34带动电池串下降的过程中，翻转吸附组件34由避让槽421穿过，从而将翻转后的电池串放置在托板42上。如图7所示，避让槽421靠近翻转机构3的一侧开口，如此，即能保证翻转吸附组件34顺利穿过避让槽421。
在一种实现方式中，翻转吸附组件34包括旋转轴341及若干吸附件342，其中：旋转轴341的第一端连接在第一升降驱动模组31的驱动端上，旋转轴341的第二端连接在翻转电机33的驱动端上。若干吸附件342沿旋转轴341的延伸方向并排安装在旋转轴341上。对应的，托板42上设置有与若干吸附件342一一对应的避让槽421。
位于出料输送线2上的待缓存的电池串的长度方向与旋转轴341平行，翻转电机33经旋转轴341驱动若干吸附件342朝向出料输送线2翻转时，若干吸附件342从出料输送线2上吸取电池串。接着，翻转电机33经旋转轴341驱动若干吸附件342朝向缓存机构4翻转，翻转后在下降过程中，若干吸附件342经对应的避让槽421穿过后将吸附在其上的电池串放至缓存机构4的托板42上。
在一些实现方式中，如图5和图6所示，电池串供料部还包括EL检测机构5，EL检测机构5设置在出料输送线2上，用于检测出料输送线2输出的电池串，翻转机构3用于从出料输送线2上拾取经EL检测机构检测合格的电池串。即，只有经检测合格的电池串才进入后道的排版及焊接工序，最终保证了光伏组件的合格率；同时，EL检测机构5直接设置在出料输送线2上，能够直接对出料输送线2上的电池串进行EL检测，从而无需将电池串从出料输送线2上抓走进行检测，避免了对电池串的抓放，有利于降低电池片的碎片率。
在一些实现方式中，EL检测机构5包括沿出料输送线的输送方向设置在出料输送线上的第一导通机构51、第二导通机构52，以及设置在出料输送线2上方或下方的EL相机。串焊机1生产好的电池串经出料输送线2输出，当电池串在出料输送线2的输送下到达预定的检测工位时，出料输送线2停止输送。第一导通机构51和第二导通机构52分别按压住电池串的第一端焊带和第二端焊带，从而导通电池串。电池串被导通后发热，温度升高。EL相机获取被导通的电池串的红外图像，并通过对红外图像实施图像分析，以确定电池串内是否存在破损、虚焊等缺陷电池片。
在一些实现方式中，第一导通机构51包括与电源正极连接的第一电极片511及第一电极片驱动部512，其中，第一电极片驱动部512安装在出料输送线2的侧边，第一电极片511连接在第一电极片驱动部512的驱动端上。第二导通机构52包括与电源负极连接的第二电极片521及第二电极片驱动部522，其中，第二电极片驱动部522安装在出料输送线2的侧边，第二电极片521连接在第二电极片驱动部522的驱动端上。
当电池串被输送至检测工位时，第一电极片驱动部512驱动第一电极片511平移及升降，以将第一电极片511压接至电池串的第一端焊带上。第二电极片驱动部522驱动第二电极片521平移及升降，以将第二电极片521压接至电池串的第二端焊带上。
在一种实施方式中，第一电极片驱动部512与第二电极片驱动部522的结构相同，第一电极片驱动部512包括两个平移驱动气缸和两个升降驱动气缸，其中，两个平移驱动气缸分别安装在出料输送线2的两侧，两个升降驱动气缸分别安装在两个平移驱动气缸的驱动端上，第一电极片511的两端分别与两个升降驱动气缸的驱动端连接，从而实现对第一电极片511的平移驱动和升降驱动。
在一些实现方式中，叠焊部还包括汇流条制备部、汇流条搬运部、汇流条承载部和焊接部；汇流条制备部被配置为制备汇流条；汇流条搬运部被配置为将汇流条搬运到汇流条承载部；汇流条承载部被配置为将汇流条移动至对应的留长焊带位置处；焊接部用于将汇流条承载部承载的汇流条焊接至留长焊带上。
通过汇流条制备部实现了汇流条的制备，通过汇流条搬运部实现了汇流条从制备部搬运到汇流条承载部，通过汇流条承载部的设置实现了汇流条的承载移动及焊接支撑，通过焊接部实现了将汇流条焊接到留长焊带上。其中，汇流条制备部、汇流条搬运部、汇流条承载部和焊接部的数量可以根据焊接效率和设备成本进行综合考量。通过设置汇流条制备部、汇流条搬运部、汇流条承载部和焊接部，在汇流条承载部和焊接部配合焊接汇流条时，汇流条制备部和汇流条搬运部可以同步进行汇流条的制备和搬运，提高汇流条叠焊的节拍。
