申请人在研发多芯线生产线时发现现有多芯线端部剥线组件都是半自动剥线设备，，用于剥线的全自动化设备如滚轮剥线设备是应用在废线回收的，使用方法是将多芯线放入滚轮剥线设备中将外皮剥除，使内芯线全部暴露在外界，然后再将内芯线放入另一型号的剥线设备中取出金属线，因此现有剥线设备不具有对多芯线进行两端端部剥线的功能，而是依靠半自动化设备对多芯线进行端部剥线，经申请人研究发现现有全自动化剥线设备对多芯线进行剥线的难点在于滚轮组与基座固定连接，导致滚轮组之间的间隙相同，仅能对直径固定的单芯线进行运输的问题，而多芯线的外皮剥除后，因为多芯线的内芯线直径小于外皮直径，所以间隙固定的滚轮组无法与内芯线抵接，导致滚轮组无法对内芯线施加拉力将内芯线的芯皮剥除的问题，为了解决上述问题申请人研发了滚轮剥线设备。
该滚轮剥线设备包括：支撑架1、收线筒2、输送组件3、切断组件4、剥线组件5、预紧组件31、上滚轮组32、下滚轮组33、内侧直线运动机构51、内侧切刀52、外侧直线运动机构53、外侧切刀54、竖向直线运动机构61、第一排线模具62、第一移动块621、第一固定块622、滑动组件623、横向直线运动机构63、第二排线模具64、第二移动块641和第二固定块642。
支撑架1包括工作台，以及固定在工作台上方的电气柜，收线筒2、输送组件3、切断组件4、剥线组件5和预紧组件31均安装在电气柜的一侧。
预紧组件31是做直线运动的弹簧、气缸、滚珠丝杠机构或液压缸等能够为上滚轮组32提供竖向下压力的运动机构，预紧组件31驱动上滚轮组32向下滚轮组33方向做直线运动，使输送组件3对多芯线施加预紧力，在图1所示的实施例中预紧组件31是气缸，使用气缸的优点在于能够配合排线组件和剥线组件5进行预紧动作或放松对多芯线的限位，便于电气工程师根据实际使用工况调整工作顺序。
收线筒2与支撑架1的上方一端转动连接，预紧组件31与支撑架1的上方另一端固定连接，输送组件3与预紧组件31固定连接，切断组件4与输送组件3靠近收线筒2的一端插接配合，剥线组件5与输送组件3远离收线滚筒的一端插接配合，多芯线的一端与收线筒2固定连接，另一端依次穿过切断组件4、输送组件3和剥线组件5，输送组件3将多芯线从收线筒2向剥线组件5方向输送。
输送组件3包括与预紧组件31固定连接的上滚轮组32，与支撑架1固定连接的下滚轮组33，以及套接在下滚轮组33外侧的输送带，上滚轮组32和下滚轮组33之间存在与多芯线相配合的预留空间，上滚轮组32和下滚轮组33的滚轮与多芯线抵接配合，上滚轮组32和下滚轮组33均至少包括八个呈一字排列的滚轮，滚轮与支撑架1转动连接，上滚轮组32和下滚轮组33的滚轮两两对应配合，上滚轮组32和下滚轮组33的滚轮延伸方向相互平行，上滚轮组32和下滚轮组33之间存在与多芯线相配合的预留空间，上滚轮组32的滚轮以及下滚轮外侧的输送带与多芯线抵接配合，滚轮和输送带的表面还开有对多芯线进行导向的凹槽。
工作原理：S1. 将多芯线远离收线筒2的一端依次穿过切断组件4、输送组件3和剥线组件5，使输送组件3将多芯线从收线筒2向剥线组件5方向输送，然后剥线组件5将多芯线远离收线筒2的一端的外皮切出豁口，输送组件3将切出豁口的外皮拉断并将多芯线远离收线筒2一端的外皮向远离收线筒2方向运输，将多芯线的主体留在输送组件3内。
S2. 剥除外皮后内芯线暴露在输送组件3的上滚轮组32和下滚轮组33之间，此时剥除外皮后内芯线的直径小于多芯线外皮的直径，导致上滚轮组32和下滚轮组33之间的间隙大于内芯线的直径，此时预紧组件31驱动上滚轮组32向下滚轮组33方向做直线运动，使输送组件3的上滚轮组32和下滚轮组33对多芯线方向施加预紧力。
S3. 剥线组件5将内芯线远离收线筒2的一端的芯皮切出豁口，输送组件3将切出豁口的芯皮拉断并将内芯线末端的芯皮运输至滚轮剥线设备外，至此完成多芯线远离收线筒2的一端的剥线工作。
S4. 切断组件4将多芯线切断后，使输送组件3将多芯线靠近收线筒2的一端向剥线组件5方向输送，然后剥线组件5将多芯线靠近收线筒2的一端的外皮切出豁口，输送组件3将切出豁口的外皮拉断并将多芯线靠近收线筒2一端的外皮向靠近收线筒2方向运输，此时内芯线暴露在运输组件的下方，预紧组件31驱动运输组件将剥离的外皮挤压形变，使运输组件的上滚轮组32和下滚轮组33都与内芯线抵接。
S5. 剥线组件5将内芯线靠近收线筒2的一端的芯皮切出豁口后，输送组件3将切出豁口的芯皮拉断并将多芯线靠近收线筒2一端的芯皮向靠近收线筒2方向运输。
S6. 剥皮组件和输送组件3将多芯线两端的外皮和芯皮切除后，输送组件3将输送组件3内的多芯线、外皮和内皮向远离收线筒2的方向运输。
在进一步的实施例中，现有技术中剥线组件5是通过气缸做与多芯线中心线相平行的直线运动机构将切有豁口的外皮从多芯线上抽出达到剥线的技术效果的，该技术存在气缸与切刀相配合，气缸将外皮抽出的过程中会带着切刀移动，存在无法在多芯线剥皮后对多芯线进行运输工作的问题，而且切刀也有与运输组件相撞的问题。
为了解决上述问题，剥线组件5远离收线筒2的一侧至少安装有两个上滚轮组32和下滚轮组33的滚轮，剥线组件5将多芯线的外皮切出豁口后，剥线组件5靠近收线筒2一侧的上滚轮组32和下滚轮组33停止工作，剥线组件5远离收线筒2一侧的上滚轮组32和下滚轮组33将多芯线端部的外皮向远离收线筒2方向输送。
通过上滚轮组32和下滚轮组33的滚轮执行剥线组件5远离收线筒2一侧的外皮的运输工作，使切刀仅进行竖向的切割工作，能够解决切刀与运输组件相撞的问题，而且剥线组件5远离收线筒2一侧的上滚轮组32和下滚轮组33执行完外皮的运输工作后，靠近收线筒2一侧的上滚轮组32和下滚轮组33还能够继续进行多芯线的运输工作。
在进一步的实施例中，在现有技术中剥线组件5使用的是压板垂直向下对内芯线进行竖向挤压，迫使内芯线分离，该技术由于内芯线的芯皮是柔性材质，导致挤压的过程中芯皮发生形变内芯线竖向挤压在一起，在剥芯皮时存在切刀将金属线切断的问题。
为了解决上述问题，滚轮剥线设备还包括与支撑架1固定连接的内芯排线组件，内芯排线组件包括与支撑架1固定连接的竖向直线运动机构61，以及与竖向直线运动机构61固定连接的第一排线模具62。
第一排线模具62包括与竖向直线运动机构61固定连接的第一移动块621，以及与支撑架1固定连接的第一固定块622，竖向直线运动机构61驱动第一移动块621向第一固定块622方向做直线运动，第一固定块622靠近第一移动块621的一端固定安装有滑动组件623，第一移动块621与滑动组件623滑动连接。
第一移动块621和第一固定块622相配合的面是与地面呈预定夹角的斜面，内芯线与斜面抵接，第一移动块621向第一固定块622移动的过程中斜面对内芯线施加斜向力，使内芯线错位分离，第一移动块621移动到预定位置时第一移动块621和第一固定块622对内芯线的芯皮施加夹紧力，使内芯线的芯皮发生形变。
通过对内芯线施加斜向的夹紧力即可使内芯线斜向错位分离，达到使内芯线直列式排列的效果，而且该技术方案仅对现有技术的模具角度进行了改进，具有结构简单生产成本低的技术优势。
在另一实施例中，滚轮剥线设备还包括与支撑架1固定连接的内芯排线组件，内芯排线组件包括与支撑架1固定连接的横向直线运动机构63，以及与横向直线运动机构63固定连接的第二排线模具64。
第二排线模具64包括与横向直线运动机构63固定连接的第二移动块641，以及与支撑架1固定连接的第二固定块642。
第二固定块642的上表面是开有至少一个与内芯线相配合的凹槽的平面。
第二移动块641的下表面远离横向直线运动机构63的一端是与第二固定块642的上表面成预定夹角的斜面，第二移动块641的下表面靠近横向直线运动机构63的一端是与第二固定块642的上表面平行配合的平面，第二移动块641的下表面平面与第二固定块642的凹槽底端之间的距离小于内芯线的芯皮直径。
横向直线运动机构63驱动第二移动块641在第二固定块642的上方做平行于第二固定块642的上表面的直线运动，横向直线运动机构63的运动方向与多芯线的中心轴相垂直。
通过第二移动块641的斜面能够将内芯线推到第二固定块642的凹槽内，达到使内芯线直列式排列的效果，而且还能够使内芯线分离有利于后续加工，通过第二移动块641的下表面的平面与第二固定块642的上表面的平行配合还能够对内芯线施加预紧力有利于后续芯皮剥除工作，该技术方案仅改变了模具的形状和直线运动机构的运动方向，具有结构简单生产成本低的技术优势。
在进一步实施例中，为了配合内芯排线组件剥除芯皮，剥线组件5还包括与支撑架1固定连接的内侧直线运动机构51，与内侧直线运动机构51固定连接的内侧切刀52，与支撑架1固定连接的外侧直线运动机构53，以及与外侧直线运动机构53固定连接的外侧切刀54，内侧直线运动机构51和内侧切刀52位于内芯排线组件靠近收线筒2的一侧，外侧直线运动机构53和外侧切刀54位于内芯排线组件远离收线筒2的一侧。
通过外侧直线运动机构53和外侧切刀54能够将多芯线靠近收线筒2一端的外皮和芯皮切出豁口，通过内侧直线运动机构51和内侧切刀52能够将多芯线远离收线筒2一端的外皮和芯皮切出豁口，通过内心排线组件内侧直线运动机构51、内侧切刀52、外侧直线运动机构53和外侧切刀54能够分别将多芯线远离收线筒2一端，以及靠近收线筒2一端的外皮和芯皮排线和剥除。
在进一步的实施例，在使用具有凹槽的模具对内芯线进行排线的过程中，容易出现一根内芯线收容在凹槽内，阻挡后面的内芯线移动导致两根内芯线堆积在同一凹槽内，出现排线失败的问题。
为了解决上述问题，第二固定块642的凹槽底端开有吸气孔，第二固定块642的平面上开有喷气孔，喷气孔位于凹槽的两侧，吸气孔与气泵的进气端连通，喷气孔与气泵的出气端连通，喷气孔将内芯线吹起后第二移动块641的斜面将内芯线推送至凹槽内，吸气孔将内芯线吸附在凹槽内。
通过喷气孔能够将内芯线吹起后通过第二移动块641的斜面将内芯线推送至凹槽内，就算是凹槽内有内芯线也能通过吸气孔将凹槽内的内芯线固定在凹槽内，通过喷气孔将后续的内芯线吹起使后续的内芯线越过收容在凹槽内的内芯线，解决了现有技术容易出现两根内芯线堆积在同一凹槽内，导致排线失败的问题。
在使用内芯排线组件的实施例中，在多芯线剥线方法中，剥离多芯线的外皮后多芯线的内芯线靠近外皮断口的一端暴露在内芯排线组件内，远离外皮断口的一端暴露在输送组件3内。
将外皮剥除后先使用内芯排线组件将内芯线排列成直列式，在通过预紧组件31驱动输送组件3的上滚轮组32向下滚轮组33方向做直线运动，使上滚轮组32和下滚轮组33都与芯皮抵接，通过内芯排线组件将内芯线排列成直列式，能够避免对芯皮切出豁口时出现切断金属线的问题。
在进一步的实施例中，为了避免外皮厚度过大导致输送组件3无法对内芯线施加足够预紧力，在剥除内芯线靠近收线筒2一端的芯皮时，内芯排线组件将内芯线排列成直列式后，内芯排线组件对内芯线施加预紧力，然后剥线组件5远离收线筒2一侧的上滚轮组32和下滚轮组33将多芯线的主体向远离收线筒2的一端输送，通过内芯排线组件对内芯线施加预紧力，能够避免外皮厚度过大输送组件3无法对内芯线施加足够预紧力的问题。
