Description
技术领域
本发明属于机器人电路板的清洗领域，具体涉及一种机器人电路板的清洗方法。
背景技术
随着社会的进步，科技的发展，机器人产也是日新月异，分拣机器人、导航机器人、焊接机器人、搬运机器人、家庭服务机器人、娱乐机器人等等。不同的机器人按照指令出色的完成的不同的任务，均需要强大的电路板。
对于电路板，清洗是电路板领域的一项重要技术，由于经过焊接后的线路板会有助焊剂、灰尘油脂、静电、环烷烃的卤化聚合物及有机卤盐等残留，对于精密的线路板而言，盐分和酸碱如在潮湿空气的周围环境下或吸水时会形成电解质，而且，一些金属如铜、铝、锡、金或银等形成电解质的阴阳极，从而形成电化学腐蚀，导致电迁移，电路遭到破坏，出现漏电、断电及短路现象。
目前电路板清洗领域清洗方法繁琐，清洗效果不理想。因此，提供一种简单的、清洗效率高的机器人电路板的清洗方法，显得尤其重要。
发明内容
本发明的目的在于提供一种机器人电路板的清洗方法，通过超声清洗条件的控制，配合复配的清洗液，清洗效率高，一次清洗合格率高达99.6％以上，而且方法简单。
本发明具体技术方案如下：
本发明提供的一种机器人电路板的清洗方法，包括以下步骤：
1)将机器人电路板置于清洗液中，浸泡；
2)取出浸泡后的机器人电路板，然后浸没于新的清洗液中，超声清洗；
3)用无水乙醇冲洗表面；自然晾干，即可。
进一步的，步骤1)所述浸泡是指在15-25℃条件下浸泡5-13min。先浸泡溶解、软化油脂、焊接助剂等，有利于后续超声清洗的污垢的彻底清除。
进一步的，步骤1)浸泡时，清洗液没过电路板1-2cm。
步骤2)中所述超声清洗是指在30～50kHZ的频率下超声清洗2-3min。前期经过浸泡、溶解、软化，所以在超声清洗时，控制超声频率较小，清洗时间较短，对缝隙之中的污垢也能较好的清洗，低功率短时间的超声可以避免超声对电路板的损伤。
步骤1)和步骤2)所述的清洗液，包括以下重量百分比的原料：
所述清洗液的制备方法为：
1)将配方量的无水乙醇、甲醇、己烷和二乙二醇二甲醚混合，搅拌均匀；
2)再加入配方量的柠檬酸、烷基酚聚氧乙烯醚APEO和椰油酸二乙醇酰胺，搅拌混合，即得。
步骤1)所述搅拌均匀是指在400-800r/min的条件下搅拌20-30min。
步骤2)中所述搅拌混匀是指在500-1000r/min的条件下搅拌20-40min。
本发明清洗液配方中，烷基酚聚氧乙烯醚APEO和椰油酸二乙醇酰胺具有协同效果，椰油酸二乙醇酰胺能够使APEO更稳定，增强去污效果。而且，两者还具有防腐和抗静电的作用。控制甲醇的加入量，与己烷、无水乙醇、二乙二醇二甲醚复配使用，能够增加对油污等污渍的溶解，促进污渍的软化，缩短浸泡和超声去污的时间。柠檬酸的加入，配合烷基酚聚氧乙烯醚APEO和椰油酸二乙醇酰胺的使用，能够很好的络合表面的金属杂质，有效的去除表面的金属杂质，防止金属杂质在其表面形成电解质的阴阳极而引起的腐蚀，具有更好的防腐效果。
与现有技术相比，本发明提供的机器人电路板的清洗方法，通过复配清洗液，而且，先在清洗液中浸泡，再超声洗涤的方法，具有高效的去除电路板污渍的作用，清洗效率高，洁净率高，而且，避免了对电路板的损伤，合格率99.6％以上。
