Abstract

一种车灯灯罩半透明镀铝的方法，检验合格的汽车灯罩经过静电除尘后，通过将蒸镀机上更换高纯度的钨丝和铝圈进行抽真空，然后通过辉光的形式对工件表面进行定向粒子流轰击，以增加工件的附着力最后钨丝加热铝圈熔化汽化，对工件表面进行蒸镀，从而实现将灯罩表面实现铝镀膜厚度在15‑20纳米之间，实现半透明的铝膜。本发明在不更换蒸镀设备的情况下，可以对不同的灯罩进行镀铝膜操作，整个过程仅需要30分钟以内，提高了工作效率，同时，每次镀膜的工件可以根据蒸镀机的镀膜空间大小进行配置，实现一次镀膜不同产品的要求，方便快捷。

Description

一种车灯灯罩半透明镀铝的方法
技术领域
本发明涉及灯具制造相关领域，特别是涉及一种车灯灯罩半透明镀铝的方法。
背景技术
车灯作为汽车行车的安全件，分为照明的前大灯，功能性的转向灯，后尾灯，日行灯等，除了大灯在行车过程中，又特别是夜间行车需要很强的透光性，其他灯作为功能性用灯，每个汽车车灯的生产厂家可以根据自身条件，对灯的外观或者功能性展示做一些调整，以区别于其他灯厂产品。在灯泡上进行镀铝实现难度比较大，如果在灯罩上进行半透明镀铝，可以达到提高灯罩使用寿命，防止灯罩老化等作用，还可以在功能性用灯时，提高车灯的辨识程度。所以对车标增加光源，白天看上去和原先效果一样，晚上点亮通过半透明灯罩反射出漂亮的光芒，满足客户的视觉效果及提高了汽车的辨识度。
发明内容
针对以上问题，本发明的目的在于提供一种车灯灯罩半透明镀铝的方法，通过真空蒸镀的方法，镀膜更均匀，透光性更好。
本发明的技术方案是通过以下工艺流程方式实现的：
步骤1：零件注塑后去除飞边，进行外观检验，合格的零件进行静电除尘，将零件摆放至周转车转运到镀膜机旁，把零件挂上夹具。
步骤2：将蒸发电极上的钨丝全部更换新钨丝，钨丝上放置专用铝圈，钨丝的纯度为99.99%，铝圈的纯度为99.99%，根据铝膜厚度选择定量的铝丝，以保证镀膜后形成的半透明铝膜透光率符合要求。
步骤3：零件挂好后关闭真空室门进行抽真空，在到达30-35Pa压力时炉体内铝棒产生辉光，产生的定向离子流对工件表面进行轰击，以增强铝膜和工件表面的附着力；在到达0.03Pa压力时给钨丝通电加热使铝圈熔化气化对工件表面进行蒸镀；蒸镀完毕高真空向低真空转换到达30-35Pa时铝爆通电产生辉光将硅油电离成SiO2覆盖在铝层表面以保护铝层被空气氧化腐蚀。
步骤4：将工件摆放在周转车，由操作员进行检验包装。
所述的铝膜厚度在15-20纳米。
本发明的优点在于不需要专用的镀膜设备就可以形成膜层均匀，与灯罩具有良好的附着力，且能够保持灯罩的透光要求。
具体实施方式
一种车灯灯罩半透明镀铝的方法，本发明的技术方案是通过以下工艺流程方式实现的：
步骤1：零件注塑后去除飞边毛刺，并进行外观检验，检查合格的零件进行3分钟静电除尘，除尘后将零件摆放至周转车转运到镀膜机旁，并把零件挂上夹具。
步骤2：将蒸发电极上的钨丝全部更换新钨丝，钨丝上放置专用铝圈，钨丝的纯度为99.99%，铝圈的纯度为99.99%，根据铝膜厚度选择定量的铝丝，以保证镀膜后形成的半透明铝膜透光率符合要求。
步骤3：零件挂好后关闭真空室门进行抽真空，在到达32Pa压力时炉体内铝棒产生辉光，产生的定向离子流对工件表面进行轰击，以增强铝膜和工件表面的附着力；在到达0.03Pa压力时给钨丝通电加热使铝圈熔化气化对工件表面进行蒸镀，蒸镀的铝膜厚度控制在15-20纳米之间；蒸镀完毕高真空向低真空转换到达35Pa时铝爆通电产生辉光将硅油电离成SiO2覆盖在铝层表面以保护铝层被空气氧化腐蚀。
步骤4：将工件摆放在周转车，由操作员进行检验包装。
成品后，进行功能性测试，特别是镀铝的附着力测试和透光性测试，透光性测试中，透光性与发光体比，透光性在30-50%左右为最佳，这样从灯罩透射出来的光效果比较好，容易形成半透明的效果。
