Abstract

本实用新型涉及一种用于波峰焊的波峰焊机喷嘴,喷嘴包括一个板,在板上有多道平行条形斜凸起,在条形凸起上均布有多排喷孔,在板凸起区域两侧焊有挡板。板下面焊有插入板,板两边有安装固定用的安装孔。这种波峰焊机喷嘴上有方便流出焊料的沟槽,所以不易产生焊渣,且有足够的焊接时间,更好地减少了漏焊、虚焊,有效地提高了焊接质量。

Description

波峰焊机喷嘴
技术领域
本实用新型涉及一种波峰焊机用的焊料喷嘴。
背景技术
波峰焊技术是电子产品中穿孔元件的焊接技术,采用波峰焊技术可以大大提高其生产效率。在焊接过程中,由于在波峰焊机的喷嘴处会产生焊锡或焊铅的氧化物渣,焊渣在波峰表面的堆积对焊接是有害的,会造成虚焊或漏焊,严重影响产品质量。
为了减少焊渣的堆积,目前波峰焊采用的技术有惰性焊接技术,即氮气焊接,这种焊接技术工艺复杂,投资大。另外还有在焊料中加入一些微量元素,以在焊料表面形成抗氧化的保护膜;或在焊料表面覆盖有机防氧化剂,以抑制焊料的氧化,但这两种方法在波峰焊时由于循环流动的焊料对保护膜的冲击,效果不明显。
实用新型内容
针对现有的波峰焊机存在的波峰表面堆积焊渣及现有的解决方案中存在的上述问题,本实用新型的目的在于提供一种波峰焊机喷嘴,这种喷嘴结构简单,不易堆积焊渣。
为了达到上述目的,本实用新型采用如下技术方案:波峰焊机喷嘴包括一个板,在板上有多道平行条形斜凸起,在条形凸起上均布有多排喷孔,在板凸起区域两侧焊有挡板。
在所述的板下面喷孔周围还可以焊有四块插入板。
在所述的板上位于挡板外两侧可以有固定安装孔。
所述的条形凸起上的喷孔可以为五排。
所述的条形凸起上的喷孔可以为四排。
所述的条形凸起与板直边的夹角可以为45°角。
这种波峰焊机喷嘴由于有多道沟槽,使得自喷孔喷出的熔化的焊料很容易从沟槽中流走,而且由于喷出的焊料的落差增大,所以流出更加迅速,不易在波峰表面堆积焊渣;而且多排喷孔,更好地减少漏焊,确保焊接时间,更适应无铅焊的要求;喷孔倾斜排列,使得波峰均匀,焊接质量更好。

图2为图1所示的波峰焊机喷嘴的俯视图;
图3为图1所示的波峰焊机喷嘴的仰视图;
图4为图1所示的波峰焊机喷嘴的A-A剖面图;
图5为图2所示的波峰焊机喷嘴的板的B-B剖面图;
图6为本实用新型的波峰焊机喷嘴的另一种实施方式结构图。
具体实施方式
下面结合附图和具体实施方式对本实用新型的波峰焊机喷嘴作进一步说明。
实施例1
结合图1到图5所示,波峰焊机喷嘴包括一个板1,在板1上表面两侧焊有两块挡板2、3,在挡板2、3之间的板上表面加工有多道条形的凸起4,条形凸起4与板的长直边的夹角为45°角,在条形凸起上钻有5排喷焊料的喷孔5,凸起4间形成流焊料的沟槽6。在板1的下表面焊接有与波峰焊机喷口配合的插入板7,4个插入板7形成一个矩形的插入槽,用于插入焊机的焊料喷口内。在板两侧还有两个固定用的圆孔8,用来将喷嘴牢固固定在焊机上。
由于喷焊料的5排喷孔位于条形凸起上,且有多条流焊料的沟槽,所以熔化的焊料从喷孔中喷出时会自斜沟槽内流向喷嘴两侧,且焊料落下时落差变大,所以能够快速的从喷嘴上流走,其中的焊料的氧化物不易停留在波峰表面上堆积成焊渣,所以能显著提高焊接质量。5排喷孔,使得焊料波峰与元件有足够的接触时间,焊接充分,大大减少了漏焊。
实施例2
如图6所示,本实施例中的波峰焊机喷嘴的板1上的喷孔5为4排,喷嘴的条形凸起4、沟槽6及插入板、挡板等与实施例1中结构相同。
