Abstract

本发明公开一种MWT光伏组件导电芯板与背板复合的方法，首先，将导电芯板放置于背板上（EVA侧朝向背板），调整导电芯板与背板间的距离，使导电芯板的焊盘均居中于背板开孔位置，并且要求导电箔长边边缘与背板长边边缘距离≥14mm，短边头部边缘距离≥19mm，尾部边缘距离≥17mm，位置确认后，压住导电芯板的焊盘位置将背板和导电芯板向上掀起，从背板面检查焊盘位置，要求四个焊盘均需处于背板开孔位置内；然后，将特氟龙高温布分别放在待复合背板和导电芯板的四角及背板开孔正上方，进行复合。本发明复合工艺简单，工艺耗时低，导电芯板和背板复合后，可大幅降低成品组件各类不良出现的概率。

技术领域
本发明涉及一种复合工艺，具体是一种MWT光伏组件导电芯板与背板复合的方法，属于MWT太阳能电池组件加工技术领域。
背景技术
MWT光伏组件由钢化玻璃、电池组、GPS、导电芯板和背板在一定温度和压力下，通过EVA的固化粘合而成。层压过程中，各封装材料热稳定性不一致，易导致导电芯板和背板的相对位置发生变化，成品组件易出现各类不良。
发明内容
发明目的：针对现有技术中存在的问题与不足，本发明提供一种MWT光伏组件导电芯板与背板复合的方法。
技术方案：一种MWT光伏组件导电芯板与背板复合的方法，包括以下步骤：
1.定位：
将导电芯板放置于背板上(EVA侧朝向背板)，调整导电芯板与背板间的距离，使导电芯板焊盘位置的四个焊盘均居中于背板开孔位置，并且要求导电箔长边边缘与背板长边边缘距离≥14mm，短边头部边缘距离≥19mm，尾部边缘距离≥17mm，位置确认后，压住导电芯板的焊盘位置将背板和导电芯板向上掀起，从背板面检查焊盘位置，要求四个焊盘均需处于背板开孔位置内。
2.复合
将特氟龙高温布分别放在待复合背板和导电芯板的四角及背板开孔正上方，通过复合工艺，固定导电芯板与背板相对位置。
复合温度为100±20℃，使用电熨斗在每块高温布上按压5～8s，等待冷却约10S后方移除高温布，复合后，要求提起导电芯板一角维持3s导电芯板与背板不脱离。
有益效果：与现有技术相比，本发明所提供的MWT光伏组件导电芯板与背板复合的方法，复合工艺简单，工艺耗时低，导电芯板和背板复合后，可大幅降低成品组件各类不良出现的概率。
