具体实施方式
以下结合附图及实施例对本发明作进一步详细说明。
参见图1所示，本发明提供一种柔性光纤带的制造装置的实施例，上述柔性光纤带的制造装置包括多个间隔涂覆组件1和一个并带组件3。
多个间隔涂覆组件1用于对多个并行排列行进的光纤2沿其长度方向间隔涂覆粘接树脂。上述并带组件3用于将多个间隔涂覆粘接树脂的光纤2进行水平密集排列，并精确控制相邻光纤之间的间隔距离，以形成光纤带4。每个光纤带4可包括6个光纤2、12个光纤2或24个光纤2。
参见图2-6所示，每个间隔涂覆组件1包括涂覆模11和设置于涂覆模11内的供料轴12，涂覆模11与供料轴12为紧密转动连接，可选地，涂覆模11与供料轴12，其一为转动件，另一为固定件。上述涂覆模11用于对光纤2间隔涂覆粘接树脂，其内设有涂覆孔道111，上述供料轴12用于向涂覆模11提供粘接树脂，其内设有粘接树脂的供料管道121。
当上述涂覆孔道111与供料管道121经转动后连通时，间隔涂覆组件1处于开启状态，粘接树脂由供料管道121进入涂覆孔道111，然后对行进至涂覆孔道111出口的光纤2涂覆一定长度的粘接树脂。当上述涂覆孔道111与供料管道121经转动后不连通时，间隔涂覆组件1处于闭合状态，涂覆孔道111出口处并无粘接树脂流出，因此，此时的光纤2表面无粘接树脂。
由于涂覆孔道111与供料管道121连通时重合部分的长度相对于整个涂覆模11的外圆周长较小，因此间隔涂覆组件1处于开启状态的时间占比相对较小，单个间隔涂覆组件1对光纤2表面涂覆时，粘接树脂的涂覆长度相对较小，而处于闭合状态的时间占比相对较大，因此粘接树脂的涂覆间距较大。
本实施例中，可根据单个光纤所需的涂覆位置和涂覆间距，设置涂覆单个光纤的间隔涂覆组件1的数量和布放位置，进而在多个并排的光纤2表面，实现沿其轴向涂覆所需长度和间距的粘接树脂。
本实施例的制造装置，通过涂覆模11和供料轴12相对转动，使涂覆孔道111与供料管道121在连通状态和非连通状态之间高速连续切换，实现对涂覆孔道111出口处的光纤进行快速地间隔涂覆粘接树脂；然后将多个间隔涂覆过粘接树脂的光纤2并带形成光纤带4，相邻光纤彼此每隔预设间隔固定连接，相对于现有的间隔切断光纤包覆材料的方式，本实施例可避免损伤光纤，且通过调节涂覆模和供料轴之间的转速，可方便调整粘接树脂的涂覆间距。
在上一个实施例的基础上，本实施例中，上述供料管道121包括相互垂直连通的横管1211和竖管1212，上述竖管1212沿供料轴12的轴向设置，且其直径大于上述横管1211直径，上述横管1211与涂覆孔道111经过涂覆模11和供料轴12相对转动后连通。
本实施例中，上述涂覆孔道111的截面为圆形，横管1211的管径为涂覆孔道111孔径的1-10倍，涂覆孔道111的长度为其孔径的2.5-50倍。可选地，涂覆孔道111的长度为5-50mm，涂覆孔道111的孔径为1-2mm。
通过调节涂覆孔道111的孔径与横管1211管径的比例，以及涂覆孔道111的长度与其孔径的比例，可进一步调整粘接树脂的涂覆长度以及涂覆间距。
本实施例中，供料管道121一端连接有送料管61，该送料管61连接粘接树脂的供料系统6。在光纤2的高速运动中，利用粘接树脂供料系统6的保压供料压力将粘接树脂由供料管道121挤入涂覆孔道111中，涂覆孔道111的扁平结构可有效平衡粘接树脂的保压供料压 力，保持粘接树脂的流速均匀，并使粘接树脂均匀涂覆在光纤2表面，以保证涂覆间距和涂覆长度的均匀性。
参见图2所示，在第二个实施例的基础上，本实施例中，上述涂覆模11为转动件，上述供料轴12为固定件，且供料管道121的出口朝向光纤2设置。参见图3所示，涂覆模11转动带动涂覆孔道111旋转，涂覆孔道111旋转至与供料管道121连通时，间隔涂覆组件1处于开启状态，涂覆孔道111的出口正对行进的光纤2，以便于供料管道121内的粘接树脂进入涂覆孔道111，随即涂覆在光纤2表面。
参见图4所示，涂覆孔道111转动至与供料管道121不连通时，间隔涂覆组件1处于闭合状态，此时，涂覆孔道111出口处并无粘接树脂流出。
参见图5所示，在第二个实施例的基础上，本实施例中，上述涂覆模11为固定件，上述供料轴12为转动件，且涂覆孔道111的出口朝向光纤2设置。上述供料轴12转动带动供料管道121旋转，供料管道121旋转至与涂覆孔道111连通时，与图3所示相同，上述间隔涂覆组件1处于开启状态，供料管道121的出口朝向光纤2，此时，供料管道121内的粘接树脂经过涂覆孔道111后涂覆在光纤2表面。
参见图6所示，供料管道121转动至与涂覆孔道111不连通时，间隔涂覆组件1处于闭合状态，此时，涂覆孔道111出口处无粘接树脂流出。
在上述实施例的基础上，本实施例中，上述涂覆模11包括套筒和设置于套筒外周面的一圈凸台，上述套筒套设于供料轴12的外表面，该凸台外周面设有一圈限位凹槽13，上述涂覆孔道111与上述限位凹槽13连通。在光纤带3的制造过程中，高速行进的光纤2至少部分位于上述限位凹槽13内，且与限位凹槽13的内壁具有间隙， 涂覆孔道111内的粘接树脂经过该间隙涂覆在光纤2表面。
本实施例中，上述涂覆模11设有两个轴承孔，两个轴承孔内均安装有轴承14，涂覆模11通过两个轴承14与供料轴12紧密转动连接。两个轴承14分别邻近供料轴12两端，上述两个轴承14之间设有两个密封圈，两个密封圈嵌入涂覆膜11内壁且位于涂覆孔道111两侧，且上述密封圈的内壁与供料轴12外壁相贴合，以进一步增加上述涂覆模11与供料轴12之间的密封性。
在上述实施例的基础上，本实施例中，上述间隔涂覆组件1还包括基座15，多个间隔涂覆组件1通过基座15固定在一个并排导轨模具5内，上述并排导轨模具5用于使多个光纤2沿同一方向并排行进，在该过程中，即可通过间隔涂覆组件1间隔涂覆粘接树脂。
由于供料管道121一端通过送料管61连接供料系统6，因此，上述基座15还开设有供送料管61穿设的通孔。当供料轴12为转动件时，供料管道121与送料管61转动连接；当供料轴12为固定件时，供料管道121与送料管61固定连接。
参见图1所示，优选地，本实施例的制造装置还包括树脂去除挡片7，该树脂去除挡片7设置在上述间隔涂覆组件1与并带组件3之间，间隔涂覆粘接树脂后的多个光纤2在进入并带组件3之前，可通过树脂去除挡片7将光纤2上涂覆厚度大于设定厚度的多余粘接树脂刮除，且树脂去除挡片7连接有树脂回收系统71，可对刮除的树脂进行回收利用，避免粘接树脂的浪费。
本实施例的制造装置还包括固化及收纤组件8，上述固化及收纤组件8包括依次设置的固化组件81和收纤线轴82。固化组件81设置在树脂去除挡片7与收纤线轴82之间，固化组件81用于将并带形成的光纤带4上的粘接树脂固化，收纤线轴82用于将固化后的光纤 带4收卷。
本实施例的制造装置还包括对上述光纤2的行进速度进行监测的测速传感器91，优选地，每个光纤2上均设置一个测速传感器91。每个测速传感器91均连接电力控制驱动系统9，电力控制驱动系统9连接并控制多个涂覆电机94，每个涂覆电机94分别通过传动带轮92和皮带93连接一个转动件。每个测速传感器91分别监测其对应的光纤2的行进速度，并反馈给电力控制驱动系统9，电力控制驱动系统9根据反馈的速度对涂覆电机94进行控制，进而实现对转动件转速的控制调节。
通过测速传感器91、电力控制驱动系统9与涂覆电机94组成一个闭环系统，实时根据每个光纤2的行进速度自动调节转动件的转速，以进一步保证每个光纤2表面粘接树脂的涂覆间距和涂覆长度的均匀性。
本实施例的制造装置还包括放纤轴组20，放纤轴组20中的放纤轴数量与光纤2数量相同且一一对应。多个光纤2通过放纤轴组20实现并行排列，随后依次经过并排导轨模具5及并排导轨模具5内的间隔涂覆组件1、树脂去除挡片7、并带组件3和固化及收纤组件8，实现在高速移动过程中完成光纤带的制造。
本发明还提供一种基于上述制造装置的柔性光纤带的制造方法的实施例，其包括步骤：
S1.行进的光纤2经过间隔涂覆组件1。
S2.通过涂覆模11和供料轴12之间转动，使多个间隔涂覆组件1在开启状态和闭合状态之间交替进行，对多个并排行进的光纤2进行间断性涂覆。
当间隔涂覆组件1处于开启状态时，涂覆模11和供料轴12之间 转动至涂覆孔道111与供料管道121连通；当间隔涂覆组件1处于闭合状态时，涂覆模11和供料轴12之间转动至涂覆孔道111与供料管道121不连通。
间断性涂覆粘接树脂后的多个光纤2，可通过树脂去除挡片7将光纤2上涂覆厚度大于设定厚度的多余粘接树脂刮除，刮除的树脂可回收利用，避免粘接树脂的浪费。
S3.通过并带组件3将涂覆粘接树脂的多个光纤2并带形成光纤带4。随后，多个光纤2水平密排形成的光纤带4进入固化及收纤组件8，首先通过固化组件81将光纤带4上的粘接树脂固化，然后通过收纤线轴82对固化后的光纤带4紧绕收卷。
本实施例中，进行间断性涂覆时，供料管道121一直处于保压供料状态。当供料管道121和涂覆孔道111经转动后连通时，由于供料管处于保压供料状态，使得涂覆孔道111内的粘接树脂可均匀地涂覆于行进的光纤2上。
本实施例中，将多个光纤2并带形成光纤带4之前，还包括：通过树脂去除挡片7将涂覆粘接树脂的多个光纤2上多余的树脂回收至树脂回收系统71。
在上述实施例中的基础上，本实施例的制造方法，还包括根据设计的相邻光纤2之间的粘接位置和光纤2的行进速度，确定间隔涂覆组件1的数量和布放位置、以及涂覆模11和供料轴12之间的转速。即，通过改变间隔涂覆组件1在并排导轨模具5内的数量和布放位置、及涂覆模11和供料轴12之间的转速，来改变不同相邻光纤2之间的粘接树脂的相对位置，得到所需粘接位置的光纤带4。
参见图7所示，当一组间隔涂覆组件1呈网状水平排布时，多个光纤2表面粘接树脂的相对位置同样呈网状排布，即得到的光纤带4 的粘接位置呈网状排布。本实施例中，三根并行的光纤2共经过5个间隔涂覆组件1，位于两侧的两个光纤2分别经过两个间隔涂覆组件1，且该四个间隔涂覆组件1的连线呈矩形，处于中间位置的光纤2经过一个间隔涂覆组件1，且位于矩形中心。
参见图8所示，当一组间隔涂覆组件1呈V字状水平排布时，多个光纤2表面粘接树脂的相对位置呈“之”字状排布，即得到的光纤带4的粘接位置呈“之”字状排布。
参见图9所示，当一组间隔涂覆组件1呈“田”字状水平排布时，多个光纤2表面粘接树脂的相对位置同样呈“田”字状排布，即得到的光纤带4的粘接位置呈“田”字状排布。
本实施例的制造方法，适用于上述制造装置，多个光纤2经由放纤轴组20、并排导轨模具5及并排导轨模具5内的间隔涂覆组件1、树脂去除挡片7、并带组件3和固化及收纤组件8组成的预设路径进行高速移动，移动过程中完成光纤带4的制造，制造效率高。
本发明不局限于上述实施方式，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围之内。本说明书中未作详细描述的内容属于本领域专业技术人员公知的现有技术。
