一种空间太阳电池阵导线电阻焊接的组合式电极结构
本专利技术涉及一种空间太阳电池阵导线电阻焊接的组合式电极结构,属于焊接设备领域。
技术介绍
空间太阳电池阵装配时,需要对连接太阳电池的金属连接片与多股线芯太阳电池阵功率传输导线进行电阻焊接,传统电阻焊接方式包括平行焊与对焊。平行焊采用一对位于焊接对象同侧、相互平行的焊接电极,由于电极平行布设且只同一个焊接面接触,焊接电流无法完全均匀地垂直穿越多层、复合结构焊接对象,带镀层金属连接片与多股线芯导线焊接稳定性受设备、工艺窗口多方面约束,过程控制难度大;对焊采用两侧同时夹持焊接对象的一对电极,焊接时电流可直接垂直穿越多层、复合结构焊接对象,焊接电流分布相对均匀,但金属连接片焊接时,其已同太阳电池及太阳电池电路基板形成组合体,金属连接片一面与待焊导线线芯接触,另一面1mm~3mm处固定有与该面平行的太阳电池电路基板,传统对焊电极受空间尺寸约束,无法夹持焊接对象成对布设。
