Description

一种灯条封胶结构
技术领域
本发明涉及封装类电子设备领域，尤其是一种灯条封胶结构。
背景技术
目前，在电子设备领域中，其PCB主板的封装是一道重要的工序，通过封装能够稳定主板的功能，提高其使用性能，常见的有针对LED线路板或基板的封装等；封装的后端工艺中胶封是一个重要的工艺流程，光源的发光光谱性质以及芯片(焊线)、荧光胶的保护可以通过分步点胶的形式来进行，参照图1和图2，现有的点胶作用于基板上时，点胶的胶水由于具有一定的流动性，会使得边缘容易溢出或者不整齐，使得封胶在基板上宽窄不一致，不仅外形上不美观，也会造成对发光性能的影响，尤其会导致基板上各处的色度不均以及色温控制不一致。
发明内容
为了解决上述问题，本发明的目的是提供一种灯条封胶结构，能够控制粘胶时胶水边缘不溢出，从而能够实现色温控制一致且保持美观简洁的外观。
为了弥补现有技术的不足，本发明实施例采用的技术方案是：
一种灯条封胶结构，包括：
灯条点胶板，上覆有用于实现所述灯条点胶板封装的灌封胶；
两组挡胶结构，分别设置于所述灌封胶在所述灯条点胶板上的延展方向的两侧，能够防止所述灌封胶在点胶时产生边缘溢出。
本发明实施例中提供的一个或多个技术方案，至少具有如下有益效果：在灯条点胶板上点上灌封胶，用于实现灯条点胶板的封装，尤其是，在灌封胶的点胶方向两侧上分别设置有挡胶结构，当灌封胶在点胶时，通过挡胶结构能够限位点胶位置，从而防止点胶时其边缘上产生胶水溢出，能够保持点胶结构整体的外观保持简洁，同时，由于点胶结构是规则完整的，即灌封胶在灯条点胶板上的分布相对更加均匀，因此，色温在灯条点胶板上各部分上也能够保持一致性。
进一步地，两组所述挡胶结构均设置为凹入或凸出于所述灯条点胶板的上表面一侧。
进一步地，每组所述挡胶结构与所述灯条点胶板之间呈层叠设置状。
进一步地，每组所述挡胶结构包括若干条平行排列设置的挡胶边。
进一步地，所述灯条点胶板设置为长条形状。
进一步地，所述灯条点胶板采用柔性PCB板或铝基板硬条。
进一步地，所述灌封胶包括有粉胶层及外封胶，所述粉胶层铺设在所述灯条点胶板上，所述外封胶铺设在所述粉胶层上。
本发明的附加方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本发明的实践了解到。

本发明的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本发明中的具体含义。
下面结合附图，对本发明实施例作进一步阐述。
一种灯条封胶结构，包括：
灯条点胶板100，上覆有用于实现灯条点胶板100封装的灌封胶200；
两组挡胶结构300，分别设置于灌封胶200在灯条点胶板100上的延展方向的两侧，能够防止灌封胶200在点胶时产生边缘溢出。
在本实施例中，参照图5，在灯条点胶板100上点上灌封胶200，用于实现灯条点胶板100的封装，尤其是，在灌封胶200的点胶方向两侧上分别设置有挡胶结构300，当灌封胶200在点胶时，通过挡胶结构300能够限位点胶位置，从而防止点胶时其边缘上产生胶水溢出，能够保持点胶结构整体的外观保持简洁，同时，由于点胶结构是规则完整的，即灌封胶200在灯条点胶板100上的分布芯片发射的蓝光与点胶粉胶发光的复合光会更加均匀，因此，色温在灯条点胶板100上各部分上也能够保持一致性。
具体地，参照图3，每组挡胶结构300可以采用一条挡胶边310或是多条平行排列设置的挡胶边310，数量设置可根据挡胶边310的厚度以及相关成本来自行决定；当设置为多条挡胶边310时，使其平行排列设置的好处在于：维持挡胶结构300的整体外观，使其不至于太过于杂乱，更重要的是，各挡胶边310之间可能容纳胶水边缘残料，该设置使得各挡胶边310的限位效果保持相同，防止出现点胶错乱。
优选地，灯条点胶板100采用柔性PCB板或铝基板硬条，即可以针对柔性线路板进行点胶，也可针对铝基板硬条进行点胶，两者均广泛应用于目前的LED灯领域，比如灯带等，是应用较为广泛的领域；当然，灯条点胶板100也可以采用类似主板，只要其需要点胶即可，即应用于点胶设备。
更进一步地，参照图4，将灯条点胶板100设置为长条形状，这符合目前生产需求且制造相对更加简洁方便，比如制造为一整块的铝基板或是一条延伸的灯带等。
更进一步地，每组挡胶结构300与灯条点胶板100之间呈层叠设置状，即每组挡胶结构300与灯条点胶板100之间存在层次性，借助于层次之间的差别，能够实现层次性地点胶，不至于一次性地将灌封胶200点完，能够避免一次点完过多灌封胶200而容易造成溢出的技术问题。
进一步地，两组挡胶结构300皆同时设置为凹入到或凸出于灯条点胶板100的上表面两侧；参照图5，若是挡胶结构300设置为凹入到灯条点胶板100的上表面一侧，即挡胶结构300为“凹型”，则挡胶结构300与灯条点胶板100之间形成了凹陷的叠层结构，当灯条点胶板100实行点胶时，灌封胶200两侧边缘则会被该凹陷的空间所容置，无法再向该空间外的区域进行扩散溢出，则能够起到良好的防胶水溢出的效果，同理地，参照图6，若是凸出于灯条点胶板100的上表面一侧，即挡胶结构300为“凸型”，则也能对灌封胶200两侧边缘进行阻挡限制，能够起到同样的技术效果。
优选地，在本实施例中，所述灌封胶200包括有粉胶层及外封胶，所述粉胶层铺设在所述灯条点胶板100上，所述外封胶铺设在所述粉胶层上。其中，粉胶层采用硅胶、环氧树脂等与荧光粉混合，外封层为单一高透光性、高密度的材料，如硅胶。其中，硅胶使用得较为广泛，尤其是室温硫化硅橡胶或有机硅凝胶，可用于电子电气元件的灌封，可以起到防潮、防尘、防腐蚀、防震、密封和防盗的作用，并提高电子电气元件的使用性能和稳定参数，而且其在硫化前是液体，便于灌注，使用方便。
以上内容对本发明的较佳实施例和基本原理作了详细论述，但本发明并不局限于上述实施方式，熟悉本领域的技术人员应该了解在不违背本发明精神的前提下还会有各种等同变形和替换，这些等同变形和替换都落入要求保护的本发明范围内。
