Description

一种屏蔽色环电感的油漆及其涂装色环电感器的工艺 技术领域
本发明涉及一种屏蔽色环电感的油漆及其涂装色环电感器的工艺。
背景技术
随着电子产品的小型化及各类高清显示器的问世和LED照明产品的低成本化普及,对现有的电感器件有了更高的要求,既要求电感器件尺寸的小型化,其电流能力不变。而且需要有屏蔽功能来减少因该电感器件工作时所产生的电磁场对其他元件的干扰。色环电感器从80年代末期传入中国内地已经20多年,发展迅速,现中国年产量已经达到70亿只,以0307产品为例,单价从最初1992年0.25元到现在的0.025元,单价格就下降10倍,主要原因是自动绕线机、全自动接脚机的使用,使成本大幅度下降。现阶段投资一条全自动色环电感生产线,以每月出货500万只为例,设备投资高达130万元人民币,以每年20万元的纯利润计算,则需要6年以上的时间才能收回设备投资,这其中还没有计算设备的零件损耗维修费用,因此大大增加了投资风险。其次随着电子产品的小型化,贴片电感的自动化生产成本也大幅下降。随着高速自动绕线机和高速全自动点胶机的成本大幅下降,导致磁胶屏蔽式贴片功率电感的价格也大幅下降,且电感具有闭合磁路的特征,大有取代色环电感的趋势。长期以来色环电感的功能单一,虽然价钱便宜,但是无革命性的技术出现。中国专利申请号为:200910041053.7的专利中,介绍一种能减少色环电感的气孔(针孔)的涂装方法,但是使用该专利涂装出的色环电感器,只能在气孔上有所减少或者杜绝。色环电感器的功能无任何改变。而在涂装色环电感出现针孔的问题上,随着UV涂料技术的不断提升以及对于一名超过5年以上的涂装技术人员来说没有技术难度,不用该专利的方法同样可以使色环电感在涂装过程中不产生针孔,这也是导致色环电感器的价格持续下降的原因之一。

与现有技术相比,本发明的优点:
1.由于使用原色环电感油漆作为涂料,但是在涂料中添加了软磁铁氧体磁粉,能够有效屏蔽色环电感器在工作中产生的漏磁对其他零件的干扰。
2.在色环电感涂料中加入磁粉,能够大幅降低涂料成本,以目前市场上色环电感油漆的价格为37元/公斤为例,在以1∶0.4比列加入固化剂后。混合搅拌均匀后的电感油漆按1∶1.5来加入磁粉。所述磁粉以锰锌铁氧体磁粉为例,锰锌铁氧体磁粉为开关电源变压器研磨气隙所产生的附属品,价值大约500-1200元/吨,烘干和重新粉粹的加工成本在300-500元/吨,这样加工过后的磁粉价格在2000元/吨,换算后大约在2元/公斤。以上述比例1∶1.5为例,也就是2公斤常规电感油漆兑3公斤磁粉,混合后的屏蔽电感涂料为5公斤,成本为80元,折合每公斤屏蔽电感涂料为16元人民币,涂料成本降低50%。
3.由于屏蔽式色环电感器涂料中加入大量的磁粉,使其电感值提升,电感值提升多少与磁粉的用量有关。电感值提升越高,同样的电感值,屏蔽式色环电感的绕线圈数明显要少于常规色环电感器的绕线圈数,这时铜线用量也比传统色环电感器用量减少,降低了铜线成本。
4.屏蔽式色环电感器圈数的减少,可以降低线圈层数,使其分布电容减少,提高了自谐频率。
5.由于屏蔽式色环电感器,使用非常细微的磁粉颗粒,在利用涂装机进行自动化涂装过程中,能够很好,很均匀的覆盖在磁芯表面,形成屏蔽层。电感器在通电工作中,电感器本身的磁场强度增大,增加了抗饱和性。经过试验和测试,均匀的磁场强度带来非常稳定的Q(品质因数)值,使Q值的一致性很好。
6.使用本发明中描述的涂装工艺方法,在涂屏蔽油漆的槽上面侧面加装小功率减速搅拌马达能够有效解决涂料中磁粉的沉淀问题。
7.用陶瓷核心绕制的屏蔽色环电感器可实现大功率,低电感值,最小可做到1NH,同时自谐频率能到5-10GHz,这在超高频军用或者民用通讯设备上面意义重大。这是传统色环电感器电感、铁氧体磁芯所做不到的。其次对比与陶瓷绕线贴片电感,由于常规的陶瓷绕线贴片电感,陶瓷体积小,这样也限制了铜线的直径和电流的大小,同样限制了功率,而陶瓷核心绕制的屏蔽式色环电感器,由于陶瓷核心 的体积加大,铜线的线径和电流也大幅提升,同时功率也大幅提升,屏蔽涂料中含有磁粉,能屏蔽电感工作中的漏磁对其他零件的干扰;这在通讯讯号电路中的作用明显。
本发明主要适用于对色环电感的优化和改进。
