Abstract
本发明涉及扁平线线圈领域，特别涉及一种用于扁平线线圈与黄铜端子焊接的方法及使用的治具。气缸轴设置在其中一个支架连接脚的连接孔内，下压柱设置在另一个支架连接脚的连接孔内；定位柱设置在下压支架的正下方；固定盘设置在支撑板的后端，旋转轴设置在固定盘上。焊接方法：沿黄铜端子两侧涂抹无铅锡膏；扁平线线圈放置在定位柱上，将涂抹锡膏的黄铜端子放在扁平线线圈下端的线圈压脚上方；气缸压紧线圈；激光发射器从20~45°角的方向发出光斑，在焊缝上0.3~1mm处形成焊道进行焊接；旋转60°焊接另一侧。本发明有效的解决了黄铜端子与扁平线使用激光焊接时锌蒸发造成铜融飞溅难题，在保证焊接强度的前提下，合格率达到100%。
