Description

一种多次布线的多主栅串连设备及电池串的串连的方法 技术领域
本发明涉及光伏技术领域，尤其是一种多次布线的多主栅串连设备及电池串的串连的方法。
背景技术
近年来，光伏产业迅猛发展，光伏市场容量不断扩大，光伏技术革新层出不穷。光伏电池片的尺寸从125mm，快速过渡到158mm，162mm，166mm，210/182mm。光伏电池片的主栅线根数从2主栅(2BB)，快速过渡到3BB、4BB、5BB、6BB、9BB、12BB，18BB。一方面，技术进步为光伏产业降本增效带来巨大的驱动力；另一方面，技术进步也带来了光伏制造设备的快速淘汰，制造设备90％的价值可能在3年内荡然无存，无法实现一次投资，长期回报的理想状态。尤其是210大硅片出现之后，预期多主栅技术会进一步扩展到24根左右。为减少贵金属Ag浆的耗费，主栅铜带的数量，未来还有可能进一步增多。
目前常见的串焊设备如图1a和图1b所示，主栅线205在主栅线布线端203上等间距地有序排列好，主栅线牵引夹子206夹持主栅线205一端，将主栅线205从主栅线布线端203牵引出来，并在布线准备台102上布线，然后移动到串焊工作台101上。主栅线205在主栅线布线端203的出线端204被切断，落入布线准备台102和串焊工作台101的限位槽内。布线准备台102和串焊工作台101为一个整体结构。布线准备台102和串焊工作台101的限位槽个数与主栅线布线数量一致。
现有设备中，有几个出线端204就有几个主栅线牵引夹子206。如果基线是 9BB设定，想要改成18BB或其他主栅线数量，则意味着需要对串焊设备进行全面改造。不仅仅需要改变送线机构(从9到18)，送线轮个数(9到18)，牵引机构(9到18个牵引夹子)，串焊工作台101对应设置改变(如预热部位等)，改造非常繁琐。

实施例1
本实施例采用小牛公司制造的158mm尺寸电池片的9BB串焊机进行改造。
本实施例中主栅线布线机构包括主栅线布线端203、主栅线牵引机构(本实施例中具体为主栅线牵引夹子206)和主栅线切断机构210，主栅布线端203通 过主栅线夹紧机构(图中未画出)固定住主栅线205的线头，以备主栅线牵引夹子206再次拉出新的主栅线205。
辅助线布线机构包括辅助线布线端、辅助线牵引机构(本实施例中具体为辅助线牵引夹子309)、辅助线切断机构305和转向轮303。辅助线布线端通过辅助线夹紧机构304固定住辅助线208，以备辅助线牵引夹子309再次拉出新的辅助线208。
辅助线牵引机构、辅助线切断机构305、辅助线夹紧机构304与主栅线牵引机构、主栅线切断机构210、主栅线夹紧机构结构和功能相同，但是布线方向不同，转向轮303用来改变辅助线的传输方向。辅助线牵引机构位于可移布线准备台202的一侧，辅助线切断机构305和辅助线夹紧机构304位于可移布线准备台202的另一侧。辅助线208通过转向轮303转向后由后至前依次经过辅助线夹紧机构304、辅助线切断机构305和辅助线牵引机构。
改造现有串焊工作台101和布线准备台102，原来串焊工作台101上主栅限位槽207为9条，在9条主栅限位槽207的基础上再增加9条的主栅限位槽207，改造后的串焊工作台101成为串连工作台201，串连工作台201具有18条主栅限位槽207；主栅布线端203上保持9根主栅线205布线；原有的布线准备台102上准备限位槽209为9条，在9条准备限位槽209的基础上再增加9条准备限位槽209，同时布线准备台102增加可沿第二方向移动的功能，改造后的布线准备台102成为可移布线准备台202，具有18条准备限位槽209。
该串连设备的连接方法包括：
(1)、可移布线准备台202沿第二方向向下移动a/2(约为7.9mm)处定位，主栅线牵引夹子206将第一批主栅线205(虚线所示)沿移动方向由主栅线布线端203牵引至可移布线准备台202的准备限位槽209前端部，此时，主栅线布 线端203上主栅线布线位置和可移布线准备台202表面的一组9根准备限位槽209一一对应，如图2a所示；
(2)、在主栅线布线端203的出线端204处，主栅线切断机构210将9根主栅线205切断，则9根主栅线205末端落入准备限位槽209中，释放主栅线牵引夹子206，则9根主栅线205落入可移布线准备台202的准备限位槽209中，如图2b所示；
(3)、可移布线准备台202沿第二方向向上移动a/2(约为7.9mm)处定位，此时串连工作台201、可移布线准备台202和主栅线布线端203对齐设置，主栅线牵引夹子206夹持位于主栅线布线端203上的主栅线205，如图2c所示；
(4)、主栅线牵引夹子206拉出第二批主栅线205(实线所示)，第二批主栅线205与第一批布线的主栅线205之间的间距为a/2；将第二次布线的主栅线205拉出并在末端剪断，使其末端落入准备限位槽209中，此时第二批主栅线205的头部仍被夹住，如图2d所示；
(5)、辅助线布线机构位于准备限位槽209上方进行辅助线布线，辅助线焊接机构工作，将辅助线208与主栅线205焊接成一个多主栅互联整体，如图2e所示；
(6)、主栅线牵引夹子206继续拉动第二批主栅线205就可以带动整个18根复合式焊带移动至串连工作台201，在电池片表面布线。
由于准备限位槽209与主栅线205位置重合，在图2a中准备限位槽209有画出，为便于视线清晰，准备限位槽209在图2b、2c、2d和2e中未画出。
如图3所示，本实施例的步骤(5)中辅助线布线和焊接的过程具体如下：当辅助线牵引夹子309夹住辅助线208的一端从辅助线布线端拉出，垂直于主栅线205布线，辅助线208另一端被辅助线切断机构305剪断，并掉入辅助线 限位槽中，辅助线布线端通过辅助线夹紧机构304固定住剩余辅助线208的线头，以备辅助线牵引夹子309再次拉出新的辅助线208。图3中设置在辅助线限位槽的上方的作为辅助线焊接机构的一个热压条310(或几个热压块的组合)向下热压就可以完成辅助线208与主栅线205的焊接。辅助线208布线的过程中，辅助线牵引夹子309和热压条310要设计让位，避免相互干扰。热压块310还可以配合辅助线顶起机构311上下压合，实现更好的焊接效果。
在本实施例中，辅助线208和主栅线205采用相同的表面涂有SiBiAg的焊带。2次9根主栅线205的布线，然后通过垂直于主栅线205的辅助线208连接到一起，组成一个具有18根主栅线205的多主栅互联整体，即复合式焊带。当主栅线牵引夹子206带动第二批的9根主栅线205移动时，18根复合式焊带作为整体一起运动。后续的串焊动作和正常串焊一致。
实施例2
本实施例采用奥特维公司制造的166mm尺寸电池片的9BB串焊机进行改造。
与实施例1不同之处在于，可移布线准备台202沿移动方向移动距离a/2约为8.3mm；步骤(5)中辅助线208与主栅线205焊接的焊接方式采用激光焊接，激光从上方直接加热并焊接主栅线205和辅助线208的交接处。
实施例3
本实施例采用奥特维公司制造的166mm尺寸电池片的9BB串焊机进行改造。
与实施例1不同之处在于，可移布线准备台202沿移动方向移动距离a/2约为6.3mm；步骤(5)中辅助线208与主栅线205焊接的焊接方式采用激光焊接，激光从上方直接加热并焊接主栅线205和辅助线208的交接处。
本实施例中，主栅线205采用表面涂有SiBiAg的焊带，辅助线208采用尼龙材料。为加强尼龙材料和涂锡焊带的结合，涂锡焊带的表面经过预处理，主 要是粗糙化。尼龙和金属间的焊接可以简单借鉴汽车工业的成熟工艺。
实施例4
本实施例设计210mm尺寸的28BB和14BB兼容的串焊机。
与实施例1不同之处在于，主栅线布线端203上保持14根主栅线205布线，主栅限位槽207与准备限位槽209都再增加14条的限位槽，串连工作台201具有28条主栅限位槽207，可移布线准备台202具有28条准备限位槽209。可移布线准备台202沿移动方向移动距离a/2约为10.5mm。
在本实施例中，辅助线208与主栅线205采用相同的表面涂有SiBiAg的焊带。2次14根主栅线205的布线，然后通过垂直于主栅线205的辅助线208连接到一起，组成具有28根主栅线205的复合式焊带。当主栅线牵引夹子206带动第二批的14根主栅线205移动时，28根复合式焊带作为整体一起运动。后续的串焊动作和正常串焊一致。
在新的设备设计中更容易实现9BB和18BB的兼容，12BB和24BB的兼容，不同运行模式可以简单快速的通过软件进行切换。比如，针对全片、半片、单晶、多晶等不同情况快速切换。
实施例5
本实施例设计210mm尺寸的28BB和14BB兼容的串焊机。
与实施例4不同之处在于，步骤(5)中辅助线208与主栅线205焊接的焊接方式采用激光焊接，激光从上方直接加热并焊接主栅线205和辅助线208的交接处。
在本实施例中，辅助线208和主栅线205采用相同的表面涂有SiBiAg的焊带。2次14根主栅线205的布线，然后通过垂直于主栅线205的辅助线208连接到一起，组成具有28根主栅线205的复合式焊带。当主栅线牵引夹子206带 动第二批的14根主栅线205移动时，28根复合式焊带作为整体一起运动。后续的串焊动作和正常串焊略不同，正常串焊采用合金焊接，而本实施例中，焊带通过胶体固定，胶体成分为UV胶，将常规的主栅焊接点改为UV胶焊接，其他部分保持一致。主栅线与光伏电池的电连接在后续的组件层压步骤完成。
实施例6
本实施例采用奥特维公司制造的166mm尺寸电池片的12BB串焊机进行改造。
将原有的布线准备台102扩大1.3倍，主栅线牵引夹子206之间的间距(也就是两根主栅线205之间的间距)也增大1.3倍，同时布线准备台102增加可沿第二方向移动的功能，成为可移布线准备台202。可移布线准备台202在原有12条限位槽的基础上，准备限位槽209再增加12根的限位槽，改造后可移布线准备台202尺寸为210mm，具有24条准备限位槽209。
该型奥特维串焊设备具有的串焊工作台采用传输带模式，因此主要的改造工作在布线准备台102。
第一次布线时，可移布线准备台202沿第二方向向下移动a/2(约为10.5mm)处定位，拉出12根主栅线205。
第二次布线时，可移布线准备台202沿第二方向向上移动a/2(约为10.5mm)处定位，拉出12根主栅线205。
最后，增加激光焊接模块，激光从上方直接加热并焊接主栅线205和辅助线208的交接处。
在本实施例中，辅助线208和主栅线205采用相同的表面涂有SiBiAg的焊带。2次主栅线205布线，然后通过垂直于主栅线205的辅助线208连接到一起，组成具有24根主栅线205的复合式焊带。当主栅线牵引夹子206带动第2批的12根主栅线205移动时，24根复合式焊带作为整体一起运动。后续的串焊动作 和正常串焊一致。
通过上述方案，我们可以将现有的12BB，166mm焊接机，简单改造为210mm尺寸硅片的焊接机，并且具有24根主栅线205。
在本发明的发明思路下，还存在其他不同的具体实施例，例如，通过调整焊接的方式，从热压或激光焊接，调整为热风、感应加热、电阻焊、红外焊接等；又如调整栅线的材料，如调整主栅线的材料，如用Al代替Cu芯。或用其他配比的Sn合金等等。又如，调整辅助线的布线方式，将现场布线改为提前截断，在需要时候搬运到主栅线上，或者采用多于一根的辅助线，等等。这些都不会改变发明的实质，因此也在本发明的保护范围内。
以上说明书中描述的只是本发明的具体实施方式，各种举例说明不对本发明的实质内容构成限制，所属技术领域的普通技术人员在阅读了说明书后可以对以前所述的具体实施方式做修改或变形，而不背离发明的实质和范围。
