Abstract
本发明公开了一种光伏焊带的喷涂制造方法,其步骤为:对铜基带进行预处理,除去铜基带表面的氧化层;在铜基带的一个表面上均匀地涂上粘结剂,形成粘结层;然后将焊粉均匀地喷在所述的粘结层上,形成焊粉层,并用超声波将焊粉与粘结剂完全粘合;翻转铜基带至另一面,重复涂粘结剂、喷焊粉及超声粘合过程;然后,在两个焊粉层的外表面上分别覆盖保护纸;收料。由于喷印焊粉的温度较低,焊粉与铜不发生反应,较方便清洗,无残留,且少用一次热加工工艺,可显著减少能源消耗。
Description
技术领域
本发明涉及一种焊带的生产方法,具体涉及应用于太阳能光伏组件连接导电的主栅焊带的制造方法,属于光伏焊带加工方法的技术领域。
背景技术
光伏焊带为光伏组件的主要辅料之一,在太阳能电池板上起着连接硅片以及导电的作用。焊带产品内在的导电性、可焊性和伸长率对光伏组件的质量起着至关重要的作用。
随着光伏技术的不断发展,对于焊带的要求和选择也越来越高。目前的光伏焊带以进入锡炉涂锡的生产方式为主,在涂锡过程中铜会部分溶解于锡液中,造成锡液中的铜含量不断升高,降低焊带的可焊性,影响后续焊接效果。很多企业采用更换锡液、调整铜带速度等方式控制,又会造成能源消耗与资源浪费。
发明内容
本发明所要解决的技术问题是:提供生产成本低、效率高、可焊性强的一种光伏焊带的喷涂制造方法,该方法生产的焊带大大降低了焊料中的铜含量。
为解决上述技术问题,本发明所采用的技术方案为:一种光伏焊带的喷涂制造方法,其步骤为:对铜基带进行预处理,除去铜基带表面的氧化层;在铜基带的一个表面上均匀地涂上粘结剂,形成粘结层;然后将焊粉均匀地喷在所述的粘结层上,形成焊粉层,并用超声波将焊粉与粘结剂完全粘合;翻转铜基带至另一面,重复涂粘结剂、喷焊粉及超声粘合过程;然后,在两个焊粉层的外表面上分别覆盖保护纸;收料。
所述的铜基带的宽度为0.5~6.0mm,厚度为0.05~0.30mm。
所述的粘结剂形成的涂层的宽度为0.5~6.0mm(与铜基带的宽度相当),厚度为0.001~0.01mm。
所述的焊粉形成的涂层的宽度为0.5~6.0mm(与铜基带的宽度相当),厚度为0.02~0.10mm。
所述的保护纸的宽度为0.5~6.0mm(与铜基带的宽度相当),厚度为0.1~0.5mm。
所述的焊粉,按质量百分比,其原料组成为:Sn60~63%、Pb37~40%。
所述的粘结剂形成的涂层,用于粘结焊粉与铜带;所述的粘结剂,按质量百分比,其原料组成为:无水乙醇50±5%、聚乙二醇40±5%、丙三醇10±2%。
本发明中采用的粘结剂形成的涂层在焊接温度下完全挥发分解,不会对焊接过程产生影响。
本发明最外层的保护纸与焊粉、粘结剂不反应,仅起到隔离空气、保护焊带的作用。在使用时先去除最外层的保护纸,将焊带对准主栅汇流带所处的位置,贴附于光伏组件上,然后进行焊接。
有益效果:本发明不同于铜带进入锡炉涂锡的传统生产方式,焊带生产过程中无需加热使焊锡熔化,避免了铜溶解在锡液中,具有生产成本低、控制容易、可以批量生产的优点,同时生产的产品满足了光伏电池片对焊带高导电性能的要求。

所述的粘结剂,按质量百分比,其组成为:无水乙醇50%、聚乙二醇40%、丙三醇10%。
所述的焊粉,为当前光伏行业通用的SnPb焊粉,按质量百分比,其组成为:Sn63%、Pb37%。焊粉尺寸粒径集中在30.82μm附近,分布范围±6.18μm。
