Description

自动补充电解液的焊道清洁机
技术领域
本发明涉及焊接领域，具体涉及一种自动补充电解液的焊道清洁机。
背景技术
金属焊接是工业领域不可或缺的一种工序，常见的焊接工艺通常使用氩弧焊、气保焊等弧焊焊接，焊接过程中，存在金属由固态加热至液态最终冷却为固态的转化过程，虽然焊接过程中使用气体保护或焊药保护，但金属加热后再凝固的过程不免有氧化的现象，使得焊道呈现发黑不洁的模样，这些氧化后的金属层除了外观不佳外，也较容易继续生锈氧化，因此在一些高要求的工件上，还必须进行焊道清洁工序，一般的清洁作法有两种，一种是打磨，利用各式打磨机以磨带、磨轮等物理性摩擦的方式将氧化层去除；另外一种是采用专门的焊道清洗机，如图1所示，焊道清洗机一般包括有直流电源1、清洁枪2和地线3，将被清洁金属工件4以地线3端部的地线夹5固定后，清洁枪2的枪头6一般采用铜头包覆吸水布或吸水棉，或者采用碳刷等兼具导电与吸水效果的设计，方便沾取电解液，直流电源供电下，清洁枪枪头6接触工件4构成电解回路，这个氧化还原的过程能使工件上的氧化金属變成离子状态进入电解液中，使得依附在金属表面的氧化物随之脱落。但传统的焊道清洗机不能自动为枪头补充电解液，必须反复以枪头粘取电解液才能进行电解清洁，操作繁琐，效率低下，而且进行清洁时需在旁边放置一瓶电解液，电解液容易被碰倒从而污染周围环境。
发明内容
