如图1至图3所示，本发明实施例一提供一种卷绕装置，包括基座10、卷绕头20及动力机构40。卷绕头20具有第一工位202、第二工位204及第三工位206，并包括转盘21、第一电机24及与转盘21转动连接的卷针22。转盘21与基座10转动连接，且转盘21对应第一工位202、第二工位204及第三工位206的位置均设有卷针22，第一电机24用于驱动卷针22转动，且第一电机24与三个工位的卷针22一一对应。当然，在其他实施例中，卷绕装置也可以仅包括一个第一电机24，并通过不同的机构将动力分别传送至不同工位的卷针22。
一并参考图4至图6，动力机构40包括均与基座10转动连接的驱动件42、传动件44及制动件46，且动力机构40与三个工位的卷针22一一对应。驱动件42包括环绕其转轴设置的传动摆臂424及制动摆臂426。传动件44包括环绕其转轴设置的第一传动臂442及第二传动臂444，且第二传动臂444与第一电机24传动连接，第一电机24通过第二传动臂444驱动卷针22转动。制动件46包括环绕其转轴设置的第一制动臂462及第二制动臂464。
初始状态时，第二传动臂444与对应的卷针22分离，第一电机24的动力无法传递至卷针22，而且，第二制动臂464与对应的卷针22连接，以限制卷针22转动。当驱动件42转动至传动摆臂424与第一传动臂442接触时，传动摆臂424通过第一传动臂442驱动第二传动臂444与对应的卷针22连接，而且，制动摆臂426与第一制动臂462接触，制动摆臂426通过第一制动臂462驱动第二制动臂464与卷针22分离，以将第一电机24的动力传递至卷针22，使卷针22转动。相反地，当第二传动臂444与对应的卷针22分离时，第二制动臂464与卷针22连接，以减小卷针22在惯性作用下旋转的角度，以减小原材料实际卷绕的长度与预设长度的偏差，从而提升产品质量。而且，传动件44及制动件46均通过驱动件42驱动，能够避免传动件44及制动件46由于电气延时等问题存在响应时间差，从而减小卷针22与第二传动臂444分离及与第二制动臂464连接的时间差，以进一步减小卷针22在惯性作用下旋转的角度。
主要参考图2、图4及图6，卷绕装置还包括与传动件44一一对应的传动组件，传动组件包括主动轮81、第一传动轮82、第二传动轮（图中未示出）、第三传动轮84及从动轮85，主动轮81与第一电机24连接，并依次通过第一传动轮82、第二传动轮及第三传动轮84与从动轮85传动连接，第一传动轮82、第二传动轮及传动件44同轴，第三传动轮84与从动轮85同轴，且第三传动轮84及从动轮85均与第二传动臂444连接，第二传动臂444通过从动轮85与卷针22连接或分离。
由于第一传动轮82及第二传动轮均与传动件44同轴，且第三传动轮84与第二传动臂444连接，传动件44转动时，第三从动轮85始终与第二传动轮啮合，以将动力传递至从动轮85，从动轮85则能够在与卷针22接触时将动力传递至卷针22，结构较为简单，并能够通过主动轮81、第一传动轮82、第二传动轮、第三传动轮84及从动轮85设计传动比。
在本实施例中，从动轮85为胶轮，能够在抵紧于卷针22时通过摩擦力带动卷针22转动。可以理解地，从动轮85选用胶轮，当从动轮85与卷针22接触时能够起到缓冲作用，并能够避免从动轮85损坏卷针22。当从动轮85磨损严重时，可对从动轮85进行更换，相对于更换卷针22，操作更为方便。
进一步地，卷针22用于与从动轮85抵接的表面设有防滑凸起，以增加卷针22与从动轮85之间的摩擦力。
主要参考图4，制动件46包括与第二制动臂464连接的制动轮466，且制动轮466为胶轮，制动轮466能够在抵紧于卷针22时限制卷针22转动。
值得一提的是，在本实施例中，制动件46通过转盘21与基座10连接，并与转盘21转动连接，转盘21转动时，制动件46跟随转盘21转动，制动件46与对应的卷针22的相对位置保持不变，且制动轮466在卷针22不转动时始终与卷针22接触。这样，制动件46除在卷针22停止转动时克服卷针22在惯性作用下转动，还能在卷针22更换工位时也限制卷针22转动，以改善原材料在卷针22工位的过程中松散的问题。
主要参考图1及图4，卷绕装置还包括第二电机61及联动件62，联动件62与三个工位的驱动摆臂422均连接，第二电机61与联动件62或其中一个驱动件42连接，便能驱动对应三个工位的驱动件42同步转动。
通过设置联动件62，三个工位的驱动件42通过联动件62实现同步运动，所有卷针22与第一电机24的动力传递均通过第二电机61控制，不会因为电气延时等问题，使得第一工位202及第二工位204的卷针22切断动力传递的时间不一致。
主要参考图4，联动件62为与转盘21同轴的圆环形结构，且联动件62与驱动摆臂422滑动连接，联动件62带动所有驱动件42转动时，联动件62环绕转盘21转动，占用的空间较小。在其他实施例中，联动件62也可以采用连杆结构。
进一步地，卷绕装置还包括与驱动件42一一对应的导向组件65，导向组件65包括与驱动件42同轴设置的弧形滑轨651、及与弧形滑轨651滑动配合的滑块652，联动件62与滑块652固定连接，并通过滑块652与驱动摆臂422滑动连接。通过弧形滑轨651与滑块652的配合，使得驱动件42运动更加平稳。
为驱动驱动件42转动，卷绕装置还包括联动凸轮63及联动摆臂64，联动凸轮63与第二电机61连接，并通过联动摆臂64与联动件62连接。采用联动凸轮63及联动摆臂64驱动联动件62，联动凸轮63持续的旋转运动能够转化为联动件62的往复运动，结构更为简单，且能简化第二电机61的控制程序。
进一步地，卷绕装置还包括送料机构（图中未示出），送料机构包括送料凸轮、送料摆臂及送料组件，送料凸轮与联动凸轮63同轴设置，并由第二电机61驱动，且送料凸轮通过送料摆臂驱动送料组件将原材料送入第一工位202，送料凸轮与联动凸轮63均由第二电机61驱动，相对于送料凸轮与联动凸轮63分别由不同电机驱动的方式，不会因为电气延时等问题使得原材料送入卷绕装置的时间与卷绕开始的时间不协调，以提升产品的质量。
值得一提的是，主要参考图1，本实施例的卷绕头20还包括与基座10转动连接的电机座26，驱动第一工位202的卷针22的第一电机24设置于电机座26上。卷绕头20还包括预卷组件，预卷组件包括预卷凸轮282及预卷摆臂284，预卷凸轮282与联动凸轮63及送料凸轮同轴设置，并由第二电机61驱动，预卷凸轮282通过预卷摆臂284驱动电机座26转动，且电机座26转动的时间早于第一电机24驱动卷针22转动的时间。也就是说，当原材料送入第一工位202的卷针22时，预卷凸轮282先通过预卷摆臂284驱动对应第一工位202的第一电机24的电机座26机械转动，由于该第一电机24固定在电机座26上，该第一电机24也在预卷摆臂284的驱动下机械转动，以带动第一工位202的卷针22预卷原材料。卷绕一定长度后，第一电机24转启动，带动卷针22高速旋转，以快速卷绕原材料。
可以理解地，由于预卷凸轮282与送料凸轮均通过第二电机61驱动，预卷凸轮282与送料凸轮同步转动，不存在电气延时，可以改善预卷动作与送料动作之间的协调性，使得第一工位202夹取原材料卷绕的位置与理想位置之间的偏差减小，以改善电容偏心的情况。若第一工位202的卷针22完全由第一电机24驱动卷绕原材料，不可避免第一电机24及第二电机61存在电气延时，就会使得卷针22夹取原材料卷绕的位置与理想位置之间的偏差不可控，从而影响产品的生产质量。
当然，为增强第一工位202、第二工位204及第三工位206动作的协调性，用于贴胶的贴胶机构91，以及用于下料的下料机构也都可以采用凸轮-摆臂的驱动方式，且凸轮均由第二电机61驱动。
本实施例的卷绕装置还包括用于推动卷针22沿其轴向移动的推针组件（涂图中未示出），以将第一工位202的卷针22推出，以夹取原材料，并将第三工位206的卷针22收回，以便于下料，且推针组件还能在卷针22不需要旋转时定位卷针22。另外，卷绕装置还包括设置在卷绕头20附近的吸尘组件，以在卷绕时吸取杂物，且卷绕装置还设置有用于检测原材料及产品质量的检测组件，并设置有对检测不合格的产品进行处理的废料处理组件，以提高卷绕装置的生产效率及生产质量。
实施例二
本实施例二与实施例一的不同之处在于，本实施例二的卷绕装置仅包括第一工位202，且基座10上对应第一工位202的位置设有贴胶机构91及下料机构，卷绕、贴胶及下料均在第一工位202进行，同一时间内，卷绕装置仅进行一个产品的加工。当然，在其他实施例中，卷绕装置还可以仅包括第一工位202及第二工位204，卷绕装置在第一工位202进行卷绕，并在第二工位204贴胶及下料。相应地，动力机构40的数量也相应减少。
实施例三
本实施例三与实施例一的不同之处在于，本实施例三的卷绕装置不包括联动件62，三个工位的驱动件42分别由不同的电机驱动。可以理解地，此时，驱动件42还可以不包含驱动摆臂422，驱动件42可以直接连接在电机的转轴上，以直接驱动驱动件42转动。
实施例四
本实施例四还提供一种钉接卷绕一体机，该钉接卷绕机除包括上述任一实施例的卷绕装置外，还包括钉接装置，钉接装置位于箔条的传送路径上，用于将导针钉接至箔条上，且钉接装置位于卷绕装置的上游，钉接有导针的箔条直接输送至卷绕装置进行卷绕，能够简化原材料与卷绕装置之间的传输。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
