Description

减影裂涂锡铜带
技术领域
本发明涉及一种涂锡铜带， 尤其是一种减影裂涂锡铜带， 用于太阳能光伏 组件中电池片之间的焊接连接。 背景技术
在制作太阳能光伏组件过程中， 电池片与涂锡铜带焊接连接， 进而使各电 池片之间电连接， 如图 1 所示， 常规的涂锡铜带为一根细长的铜薄片， 表面包 裹着锡层， 铜薄片无任何裁切处理， 电池片与铜带焊接时， 焊接产生的应力会 造成电池片破片或影裂， 进而影响整个太阳能光伏组件的稳定性。 发明内容
本发明要解决的技术问题是： 克服现有技术的不足， 提供一种减影裂 涂锡铜带， 电池片与铜带焊接时， 电池片不易破片或影裂， 整个太阳能光 伏组件发电更加稳定。
本发明解决其技术问题所采用的技术方案是： 一种减影裂涂锡铜带， 具有铜带薄片， 所述的铜带薄片的长度方向边缘裁有断口， 所述的断口在 铜带薄片的宽度方向延伸， 断口的长度小于铜带薄片的宽度。
进一步地， 所述的铜带薄片的厚度为 0. 05〜2mm，所述的铜带薄片的 宽度为 l〜6mm。
进一步地， 所述的断口为直线形并垂直于铜带薄片的长度方向边缘。 进一步地， 所述的断口为不规则波浪形。
进一步地， 所述的断口为向上倾斜或向下倾斜的斜线形。 进一步地， 所述的断口在铜带薄片长度方向两侧交错排列。
进一步地， 所述的铜带薄片表面涂有锡层。
本发明的有益效果是：本发明的涂锡铜带通过在铜带薄片的长度方向 边缘裁有断口， 电池片与涂锡铜带焊接时不会产生应力， 电池片不易破损 和影裂， 因此， 有效的降低了电池片的破片和影裂， 进而提高了整个太阳 能光伏组件的稳定性。 断口的长度小于铜带薄片的宽度， 铜带薄片不会断 裂， 断口可以是直线形、 不规则波浪形或斜线形， 断口交错排列在铜带薄 片的长度方向两侧，可使电池片焊接在涂锡铜带的任意位置均不易破片和 影裂。 附图说明
下面结合附图对本发明进一步说明。
图 1是现有技术的结构示意图；
图 2是本发明第一个实施例的结构示意图；
图 3是本发明第二个实施例的结构示意图；
图 4是本发明第三个实施例的结构示意图；
其中： 1. 铜带薄片， 2.断口 具体实施方式
如图 2图 3图 4所示的减影裂涂锡铜带， 具有铜带薄片 1， 铜带薄片 1 的厚度为 0. 05〜2mm，宽度为 l〜6mm。 铜带薄片 1 的长度方向边缘裁有 断口 2， 断口 2在铜带薄片 1的宽度方向延伸， 断口 2的长度小于铜带薄 片 1的宽度， 断口 2在铜带薄片 1长度方向两侧交错排列， 铜带薄片 1表 面涂有锡层。
