Description

一种组装式的LED长灯带及制作方法 技术领域
本发明涉及LED灯带领域，具体涉及一种组装式的LED长灯带及制作方法。
背景技术
现有技术制作LED灯带有以下方案：
1、是用多个单条短灯带一条一条组装在长排线上，效率非常低，人工成本很高。
2、还有一种方案是直接制作长排线双层线路板，然后用长板SMT机及长板生产线贴元件，设备投资很大，需要的生产场地很长，而且良率很低，并且灯带弯曲使用时，因两层电路之间所有位置都已粘牢结后在一起，弯曲时，背面排线会顶断正面线路。
3、本发明人之前也有专利号为：201020600775.X和201420541246.5的专利，用短灯带组装到连体长排线的做法，但是存在以下缺陷：
①、长灯带的制作方式是由多条单条短灯带首尾排列用人工整条贴双面胶的方式贴到长排线上，效率很低。
②、单条组装到长排线上，也很难保证整齐对位将短灯带粘到长排线上，灯带两边的侧面，短灯带线路板侧面和长排线的侧面不在一个切刀面上，侧边不整齐，外观很差。
③、是用双面胶将短灯带整面粘接到长排线上，因为整体所有位置粘牢在一起，背面排线太硬，导致灯带弯曲使用时，背面排线顶住正面线路板时，正面软板没有和排线形成有分层伸缩避让空间，导致很容易把正面线路板线路顶断。
为了克服以上的缺陷和不足，本发明将多张包含多条短灯带的连体短灯带，首尾排列组装到含多条排线的长排线板上，一般来讲，每张连体短灯带通常都是尺寸是250mmx500mm～1000mm，而且每张里至少20条，含多条排线的连体长排线板也是用同样宽度(250mm宽)，同样条数(至少含有20条)，所以，一次一张同时组装的是20条以上的短灯带到长排线上，和单条组装相比提高了20倍以上的效率，制作效率非常高，而且制作粘接胶是在连体的LED短灯带的背面，或者在连体的长排线板用印刷机印胶粘剂到连体的板上，一般来讲，用网印一次印刷的范围在250mm宽，500～1000mm长的范围，一次只需5～10秒的时间、或者用多个打胶头的打胶机打胶，在250mm宽，500～1000mm长的范围一次打胶，所以印刷效率很高，而且是在板上间断式施加胶粘剂，不仅用胶量低，而且两层组装在一起后是形成多处分层的间断式粘接，制作的这种分层结构的灯带在弯曲使用时，正面线路层没有被背面线路层全部粘牢控制，正面电路就能在灯带弯曲时有弹性和伸缩自由度，弯曲时线路及灯珠不易断裂，元件脚不易脱离，弯曲时，背面排线电路没有把正面线路全部控制牢后硬顶，顶断正面电路及元件的风险降低，元件脚被顶起脱离线路板的风险降低，同时又因多个位置粘胶形成间断式的多处粘接，又保持了灯带的整体结构形态的稳定性，两层不错位不散乱，组装时，是将多张连体短LED灯带首尾排列贴到长排线上，然后将短灯带和排线焊接连接导通到长排线上，焊接也是采取多焊头的自动焊接机，在连体的短灯带两端将多条短灯带焊到多条长排线上，和单条焊接相比大大提高了生产效率，制作好含多条长灯带的连体长灯带后，再用刀模分切成单条长灯带，制作的长灯带的两个侧面，短灯带线路板的侧面和排线板的侧面，都分别在一个整齐的切刀面上，外观整齐美观。
