在光伏切割技术领域，针对截断机、开方机、切片机、甚至磨削机，目前多数都为单工位设置，每个工位设置有一个切割机构和一个收放线装置，能够实现对一个待切割件的加工，同一车间内工位布局密度小，占用空间大，生产效率相对较低。
参见图1至图3，图1为本申请实施例提供的一种线锯装置的结构示意图，图2为本申请实施例提供的一种线锯装置的一个视角的立体结构示意图，图3为本申请实施例提供的一种线锯装置的另一个视角的立体结构示意图。本申请实施例提供了一种线锯装置1，可以应用到截断机、开方机或者切片机等。线锯装置1包括第一收放线机构10和第二收放线机构20、多个切割机构30，第一收放线机构10和第二收放线机构20分别用于收纳和释放切割线311，多个切割机构30分别设置于第一收放线机构10和第二收放线机构20之间，切割线311分别往复绕设于每个切割机构30，使得每个切割机构30上的切割线311能够独立实现对待切割件2的加工。
通过在第一收放线机构10和第二收放线机构20之间设置多个切割机构30，使得多个切割机构30共用一套收放线装置(包括第一收放线机构10和第二收放线机构20)，相对于目前的单工位设置方式节省了收放线装置的数量，从而提高了工位布局密度，减小占用空间，提高工作效率和加工产能。
在一些实施例中，切割线311可以为金刚线。
在一些实施例中，线锯装置1还可以包括第一收放线驱动机构和第二收放线驱动机构，第一收放线驱动机构与第一收放线机构连接，用于驱动第一收放线机构绕自身轴线转动；第二收放线驱动机构与第二收放线机构连接，用于驱动第二收放线机构绕自身轴线转动。
在一些实施例中，第一收放线驱动组件和第二收放线驱动组件可设置为气缸等直线动力驱动设备。
在一些实施例中，多个切割机构30为并联设置，每个切割机构30能够独立工作，且切割线311的张力不会相互影响，能够使得每个切割机构30的切割稳定，在节省硬件成本的基础上大大提高工作效率和加工产能。同时，通过该并联设计为整机框架提供了更多的安装空间，以方便电气控制系统等，为后续设备的改良提供了更多的可能性。
在一些实施例中，切割机构30包括两个切割辊310，两个切割辊310间隔设置，切割线311往复绕设于切割辊310。
在另一些实施例中，切割机构30也可以包括三个、四个或其他数量的切割辊310，线锯装置1可以设置包括相同数量的切割辊310的多个切割机构30，也可以设置包括不同数量的切割辊310的多个切割机构。
在另一些实施例中，切割辊310也可以替换为切割轮，以进行单线切割。
参见图4，图4为本申请实施例提供的另一种线锯装置的立体结构示意图。在一些实施例中，切割机构30包括两个切割辊310和至少一个辅助切割辊320，两个切割辊310、至少一个辅助切割辊320分别间隔设置，切割线311往复绕设于切割辊310和辅助切割辊320上。
在实际切割的过程中，由于切割辊310的直径有限，当涉及到切割大工件时会产生切割空间不足的问题。在切割机构30设置两个切割辊310和至少一个辅助切割辊320，辅助切割辊320能够扩大两层切割线网之间的切割空间，从而解决切割空间不足的问题，还能够减小相邻两个切割辊310之间切割线311的拖拽力，提高线锯装置的稳定性。
在一些实施例中，辅助切割辊320可以为从动轮，也可以与驱动机构连接。该结构能够增加线锯装置1的对不同尺寸待切割件的适用性，提高线锯装置1的整体性价比。
在一些实施例中，切割机构30的数量为二，两个切割机构30中的一个包括两个切割辊310，另一个包括两个切割辊310和至少一个辅助切割辊320。能够同时切割大工件和普通工件，提高了线锯装置的适用性。
随着光伏切割技术领域的发展，针对单晶硅片等工件切割的精度要求越来越高，所以要想实现高精度切割，就需要对切割设备做近乎完美的设计，目前多线切割设备多为单工位平行线网的结构设计，该传统设备由于切割稳定所以被大多数人所接受，但是其切割工件的质量也已经被现有技术人员运用到了近乎极致，所以要想在工件切割上有进一步的突破，需要从多线切割设备上做进一步改进，尤其是针对切割过程中针对切割线冷却降温以及设备反向间隙多带来的切割问题，需要亟需被解决。
参见图5至图8，图5为本申请实施例提供的另一种线锯装置的结构示意图，图6为本申请实施例提供的另一种线锯装置的一个视角的立体结构示意图，图7为本申请实施例提供的另一种线锯装置的另一个视角的立体结构示意图，图8为本申请实施例提供的另一种线锯装置的立体结构示意图。在一些实施例中，至少一个切割机构30的两个切割辊310的中心连线与竖直面之间形成预设倾斜角，使得切割线311在切割工作时也呈倾斜设置，此结构能够增加切割线311的带液能力，在工作的过程中提高了冷却效果，从而降低切割线311因为温度导致张力的变化，增加了切割线网的工作稳定性，使得切割出的工件质量更高；还能够平衡掉进给机构330的重力沿斜向进给方向的分力，对进给机构330始终保持有斜向下的作用力，能够消除进给机构330的丝杆的反向间隙，尤其是在切割线换向时，能够将换向切割对待切割件2切割品质的影响降低一个层次；切削液更容易进入切削区，便于冷却，切削液在晶体斜上方注入，利用切削液自重沿线缝流入切削区，实现对切削区内的金刚线和晶体的冷却；便于切屑在重力作用下排出切割区，线缝中的放电作用可以更突出。
在一些实施例中，两个切割辊310的中心连线的垂线呈斜向上设置，能够增加切割线311的带液能力。
在切割时，待切割件2可以沿倾斜的切割线311的垂直方向向切割辊310的方向移动，斜线网结构能够利用切割机构30的重力平衡掉一部分切削时产生的作用力合力，切割产生的切削屑在重力分力的作用下可自动排出，有利于线锯装置1的养护。斜线网相比平线网，带液能力更强，切割线311在切割区能获得的润滑和冷却效果更好，更大限度的降低进给机构330的丝杆的反向间隙对待切割件2带来的不利影响，切割后的工件可以获得更良好的加工表面质量。
在一些实施例中，相邻两个切割机构30的预设倾斜角沿竖直中心线对称设置。
其中，竖直中心线为在水平方向上位于相邻两个切割机构30中间的竖直的线。
通过使得相邻两个切割机构30的预设倾斜角沿竖直中心线对称，切割机构30以及匹配的进给机构330对称设置在切割室内，切割中产生的进给力和发热对称，主要热源如主轴、电机、切割辊310和进给机构330都呈现对称布置，可以起到热平衡作用，从而使整机的热变形相互抵消，达到稳定状态。
参见图9，图9为本申请实施例提供的另一种线锯装置的结构示意图。在一些实施例中，预设倾斜角θ的角度为25度至75度，例如25度、50度或75度等。
通过将预设倾斜角θ的角度设置为25度至75度，能够更好地平衡切割机构30自身的重力和切割线330的带液能力，使得切割效果更好。
在一些实施例中，预设倾斜角θ的角度为30度至60度，例如30度、45度或60度等。
参见图10，图10为本申请实施例提供的另一种线锯装置的结构示意图。在一些实施例中，线锯装置1还可以包括角度调节机构340，角度调节机构340用于带动两个切割辊310中的一者相对另一者移动，以调节预设倾斜角的角度。
角度调节机构340可设置为直线滑移驱动机构等，带动两个切割辊310中的一者从第一预设位置移动至第二预设位置，在第一预设位置时，两个切割辊310的中心连线与竖直面之间的夹角为第一预设角度；在第二预设位置时，两个切割辊310的中心连线与竖直面之间的夹角为第二预设角度，第一预设角度和第二预设角度不等，由此以调整预设倾斜角，满足不同设置需要。
通过调节预设倾斜角的角度，根据需要调整切割区内的切割线311的倾斜角，更好地适应不同线切割需要，提高线锯装置1的适用性。
参见图11，图11为本申请实施例提供的另一种线锯装置的结构示意图。在一些实施例中，切割机构30包括四个切割辊310，四个切割辊310分为两组切割辊组，每组切割辊组包括两个切割辊310，两组切割辊组沿竖直中心线对称设置，每组切割辊组的两个切割辊310形成预设倾斜角，且两组切割辊组的两个预设倾斜角沿竖直中心线对称设置；切割线在四个切割辊上往复绕设以形成切割线网，切割线网用于对待切割件进行侧向切割。
双侧双工位双棒切割，切割效率提升一倍，并且不同于传统利用上下线网实现双棒切割时下线网工位会收到上线网工位切削液和硅粉等污染，采用左右两侧布局的斜线网切割可以做到两侧独立对称切割，工况相同，获得的切割质量和效率完全一致。
在一些实施例中，线锯装置还可以包括放电加工装置，为多线切割与放电加工的结合，由此以实现高效切割同时获得更好的加工质量，放电加工装置可与切割机构30连接，以为切割线311提供电源。
参见图1和图2，在一些实施例中，线锯装置1还包括过轮机构40，过轮机构40设置于相邻两个切割机构30之间、第一收放线机构10与切割机构30之间、第二收放线机构20与切割机构30之间的至少一者，过轮机构40用于支撑切割线311。
例如，图1所示的相邻两个切割机构30之间、第一收放线机构10与切割机构30之间、第二收放线机构20与切割机构30之间都设置有过轮机构40。
通过将相邻的切割机构30通过过轮机构40并联连接，能够减轻并联工位之间切割线311的张力，避免了通过直接并联多工位中连接处的切割线311张力过大导致断线或者跳线的问题。
在一些实施例中，过轮机构40包括导向轮410和/或张力轮420。
在一些实施例中，可以通过张力轮420和导向轮410配合实现切割线310的横向排线，通过转动张力轮420和沿水平方向移动靠近收放线装置的导向轮410以调节切割线310的张力大小。
在另一些实施例中，也可以通过张力轮420实现切割线310的横向排线，通过沿水平方向移动张力轮420以调节切割线310的张力大小。
在一些实施例中，线锯装置1还可以包括张力传感器，张力传感器设置于第一收放线机构10和/或第二收放线机构20上，张力传感器与控制组件连接、以对切割线的张力进行检测并反馈至控制组件。具体的，第一收放线装置1和第二收放线装置9上分别安装张力传感器，具体为设置在相应的收放线轮上。张力传感器与控制装置连接，以将数据发送至控制装置，控制装置可以获得张力传感器上的实时张力合力，对于精确了解张力变化，进而有据优化切割线311的张力提供数据支撑。
在一些实施例中，过轮机构40包括两个导向轮410和张力轮420，张力轮420设置于两个导向轮410之间，能够辅助实现高精度的切割工作。两个导向轮410用以固定张力轮420，有利于 稳定张力轮420的张力波动，使排线卷径误差、排线误差、排线换向延迟或加减速等参数的误差以及排线所产生的切割线311与原排线导轮的包角误差不会影响到位于张力轮上的张力传感器的测量结果，提高张力测量的准确性。
在一些实施例中，张力轮420为直线张力轮。通过设置直线张力轮能够在调整张力的同时使其两侧的进线和出线方向不发生变化，从而不会因为张力调节改变局部切割线311受力不均匀的问题。解决因为摆杆摆动角度变化导致的导向轮410两端切割线311的运丝速度差以及张力差的问题。
通过设置两个导向轮410和一个张力轮420，能够克服单个导向轮410设计位置布局受到限制的问题，而且通过直线张力轮能够保证切割线311的张力的高效调节，相比传统摆杆方式可以规避摆角误差引起的张力轮两侧金刚线的张力不同步，从而提高切割的精度。
具体的，过轮机构40位于切割机构30和第一收放线机构10之间，绕设于过轮机构40的一端的切割线311与切割机构30连接，绕设于过轮机构40的另一端的切割线311与第一收放线机构10连接。
过轮机构40位于切割机构30和第二收放线机构20之间，绕设于过轮机构40的一端的切割线311与切割机构30连接，绕设于过轮机构40的另一端的切割线311与第二收放线机构20连接。
过轮机构40与第一收放线机构10配合，过轮机构40与第二收放线机构20配合，将收放线装置同时作为排线机构，保持线轴出线与导向轮410排线垂直的横向排线功能，与张力轮420靠近的导向轮410固定有利于稳定张力轮420的张力波动，使排线卷径误差、排线误差、排线换向延迟或加减速等参数的误差以及排线所产生的切割线311与原排线导轮的包角误差不会影响到位于张力轮420上的张力传感器的测量结果。
在一些实施例中，针对两个工位(切割机构30所在的位置)之间，第一工位的出线方向与第二工位的进线方向相平行，这样能够通过导向轮410或者导向轮410和张力轮420的组合，抵消掉两个工位之间切割张力的叠加，降低断线风险，同时也能够实现并联更多的切割机构30。
在另一些实施例中，张力轮420也可以为摆杆张力轮。
在另一些实施例中，根据切割精度的要求，也可以不设置导向轮410或张力轮420。如采用短排线方式，调整收放线装置、排线组件及张力轮420位置，使其靠近切割区，缩短从收放线装置至切割辊310的传动环节；同时，减少传动部件，可以通过减少导向轮410数量或者不使用张力轮420来解决。
随着近年来鼓励清洁能源的发展，单晶硅片材料的需求量越来越大，现有的光伏切割设备在提高生产效率上也爆出了越来越多的问题，如单一工位设计的问题，简单的串联工位很难实现切割要求，且设备的整体成本较高。
在一些实施例中，切割线311缠绕在第一收放线机构10上，经靠近第一收放线机构10的过轮机构40，再绕设于切割机构30的两个切割辊310的周向外壁，最后到第二收放线机构20，实现上一个单向循环的走线运动。在相邻的一个往复周期内，切割线311从收线侧再反向经上述路径回到放线侧实现反向走线运动。
参见图1至图3，本申请实施例提供了一种多线切割设备，包括底座50及设置于底座50上的切割室支架60，切割室支架60形成切割室，切割室用于容置多个切割机构30，底座50的两侧形成收放线室，两个收放线室分别用于容置第一收放线机构10和第二收放线机构20。
通过将多个切割机构30设置在同一个切割室内，能够在线锯装置1提高工作效率的基础上，大大的降低了设备的占用空间，能够实现同等车间的面积条件下，布设更多的多线切割设备，从而提高加工产能。通过将第一收放线机构10和第二收放线机构20设置在切割室的外部，能够避免切削液腐蚀第一收放线机构10和第二收放线机构20。
在一些实施例中，多线切割设备为切片机。
在另一些实施例中，转换切割方向，第一收放线机构10起到收线作用，第二收放线机构20起到放线作用。
在一些实施例中，多个切割机构30并排同向设置在切割室内，能够最大限度的节省切割空间，同时方便工作人员操作，因为工作人员可以同时观察到每个工位的工作状况，并通过共用的电气控制系统进行控制，不需要在多个电气控制系统之间来回跑动操作。
在一些实施例中，一个切割室内可设置2个或3个切割机构30，此设置方式中切割线311 的切割效果以及液路控制装置的工作稳定性都较为理想。
在一些实施例中，切割室支架60包括沿第一方向相对设置的第一立柱610和第二立柱620，第一立柱610的高度小于第二立柱620的高度。切割机构30包括切割辊310和第一驱动器，切割辊310通过轴承转动设置于第一立柱610和第二立柱620之间，第一驱动器设置于第二立柱620背向第一立柱610的一侧，且通过轴联器与切割辊310连接。
在一些实施例中，多个切割机构30沿第二方向间隔设置于切割室。多线切割设备还包括多个进给机构330，多个进给机构330与多个切割机构30一一对应；进给机构330通过滑动机构设置于切割室支架60上，且位于切割室内，用于带动待切割件2相对切割线311运动。
通过使得第一立柱610的高度小于第二立柱620的高度，相比包括相同高度的两个立柱的切割室支架，一是方便多线切割设备生产时，切割室更加便于观察，二是可以将进给机构330安装在第二立柱620上，使整个多线切割设备布局更加合理，工作时更加的稳定。
在一些实施例中，滑动机构包括滑轨340和第二驱动器，滑轨340设置于第二立柱上，进给机构330滑动设置于滑轨340上，第二驱动器与进给机构330连接。
在一些实施例中，第一收放线机构10可以包括收放线辊110，收放线辊110与切割机构30之间可以设置排线组件120，排线组件120与收放线辊110串联设置于底座50的侧边，收放线辊110用于切割线311的绕线，排线组件120用于切割线311的排布。
在另一些实施例中，收放线辊110与排线组件120可以为一体设置，通过一体设置能够更大限度的降低排线组件120的占用空间，直接通过控制收放线辊110进行排线即可。
在另一些实施例中，切割辊310可以通过排线组件120与底座50相连接，排线组件120能够直接滑动控制收放线辊110进行排线运动，缩短了切割线311从收放线辊110进入切割室的距离，同时该设计也节省了收放线装置的占用空间，为整机的设计布局时提供了更多的灵活性。
在一些实施例中，相邻的切割机构30之间的过轮机构40可以设置在第二立柱620上相对于切割辊310的水平位置上方或者下方的位置。
在一些实施例中，多线切割设备还包括电气控制安装室，电气控制安装室位于第二立柱620上或位于底座50上、第二立柱620背向第一立柱610的一侧。电气控制安装室用于容置电气控制装置，电气控制装置包括切割控制机构和进给控制机构，切割控制机构用于控制切割机构30工作，进给控制机构用于控制进给机构330工作。
在一些实施例中，进给控制机构包括多个进给控制单元，多个进给控制单元与多个进给机构330一一对应，且相互独立电连接。该结构可以实现在切割的过程中单独控制待切割件的进给也可以同时控制多个切割机构30的待切割件同步进给，增加了使用的灵活性，同时也避免了当某一个切割机构30上进给机构330出现故障时，影响其他切割机构30的工作。
在一些实施例中，多线切割设备还包括液路控制装置70，液路控制装置70与电气控制装置并排设置在底座50上、第二立柱620背向第一立柱610的一侧，液路控制装置70分别与喷淋装置、切割室连接，用于为切割机构30提供切割液，喷淋装置安装在对应切割辊310处的切割室框架60上或者安装在进给机构330下方。
通过设置一个切割室且将管路与切割室相连接，方便液路控制装置70的布设的同时，能够避免现有技术中多个切割机构30之间共用液路控制装置70时一个切割机构30的切割室故障而影响另一个切割室内的液路稳定。
在另一些实施例中，液路控制装置70还可以设置在底座50内或底座50的一侧。
在一些实施例中，多线切割设备还包括排污装置，排污装置设置于切割室的底部，排污装置的入口端设置有过滤网，入口端的数量为至少一个。通过共用排污装置能够节省排污硬件成本，且更方便排污装置的布设。
参见图12，图12是本申请实施例提供的多线切割设备的控制方法的流程示意图。多线切割设备的控制方法包括：
S1、判断并联设置的多个切割机构上的待切割件是否在预定位置。
S2、若待切割件在预定位置，则通过切割控制机构控制所有切割机构的第一驱动器同步启动，以使得连接于第一驱动器的切割辊带动绕设于切割辊的切割线工作；并通过进给控制机构控制分别与多个进给机构连接的多个第二驱动器启动，以使得进给机构运动，进而使得设置于进给机构的待切割件相对切割线运动。
S3、若待切割件不在预定位置，则调整待切割件的位置，使得待切割件到达预定位置。
S4、判断切割线是否存在工作异常。
S5、若切割线存在工作异常，则通过切割控制机构控制第一驱动器停止，通过进给控制机构控制第二驱动器停止，并进行故障处理。
S6、若切割线不存在工作异常，则判断进给机构是否存在工作异常。
S7、若进给机构存在工作异常，则进给控制机构控制对应进给机构的第二驱动器停止，并对该进给机构进行故障处理。
S8、若进给机构不存在工作异常，则切割线和进给机构保持工作状态直至切割工作结束。
在一些实施例中，可以实时监控切割线、进给机构的工作情况，并将每个切割机构的切割情况分别反馈给电气控制系统。
在一些实施例中，进给控制机构用于通过多个第二驱动器控制多个进给机构同步进给。
在另一些实施例中，进给控制机构用于通过多个第二驱动器控制多个进给机构分别独立进给。
具体的，多工位可同步切割，一个电气控制系统即可完成全部操作。同时，本申请中多个切割结构30的进给机构330为独立进给，在同一电气控制系统中的一个界面中设置独立进给。
双/多工位的多线切割机切割控制流程：同步进给时，各工位无异常，则同步进给至切割结束。切割过程中出现断线等异常，则需要多个工位同时停机处理，异常处理后，同步进给至切割结束。当出现进给异常时，将进给异常工位停机进行异常处理，其他工位正常工作，异常处理后的工位独立进给至切割结束。
在另一些实施例中，各工位切割进度不同步时，各工位独立进给至切割结束。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互结合。
以上仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
