本申请还提供的一种搭纱方法，包括以下步骤：
步骤一：控制器控制自动搭纱装置从起始位向纤维束4移动，当自动搭纱装置移动至纤维束4的指定位置时，压紧轮驱动气缸305的连杆缩回，通过压紧轮连接臂303带动压紧轮302向下移动，压紧轮复位弹簧304被压缩，将纤维束4压紧在出纱轮315上，与压紧轮302连接的第一轴承306随着压紧轮302移动而向下运动，第一轴承306连动挑纱轮连接臂308，挑纱轮弹簧309收缩，拉动挑纱轮连接臂308向上运动，从而带动挑纱轮307将纤维束4纱头上挑，位置传感器检测到压紧轮302压紧到位，并将到位信号传送给控制器；
步骤二：控制器接到压紧轮302到位信号后控制直线模组2向前移动，带动滚轮送纱组件3及纤维束4接近缠绕工件5，同时，滑动块311沿滑槽601逐渐由高位向低位滑动，带动挑纱轮连动曲臂310动作，挑纱轮连动曲臂310另一端的第二轴承312向上移动，挑纱轮弹簧309继续拉动挑纱轮307上挑，将纤维束4的纱头缠绕在压纱轮313上，此时直线模组2已经移动到预定位置，控制器控制直线模组2停止运动；
步骤三：直线模组2停止运动后，控制器控制压纱轮驱动气缸314连杆伸出，带动压纱轮313及纤维束4向缠绕工件5移动，使纤维束4纱头与缠绕工件5紧密接触，以上动作将纤维束4的纱头压靠在缠绕工件5上；
步骤四：压纱轮313移动到位后，控制器控制缠绕工件5转动，同时控制器控制出纱轮驱动电机317工作，带动出纱轮315转动，克服纤维束4的张力，将纤维束4缠绕在缠绕工件5上完成搭纱动作；
步骤五：搭纱动作完成后，控制器控制压纱轮驱动气缸314的连杆缩回，压纱轮313复位，位置传感器检测到压纱轮313复位后将信号传送给控制器，控制器接到信号后控制压紧轮驱动气缸305 的连杆伸出，压紧轮复位弹簧304放松，将压紧轮302复位，解除对纤维束4的压紧；
步骤六：压紧轮302复位后，控制器控制自动搭纱装置远离纤维束4，自动搭纱装置回到起始位后，控制器控制直线模组2移动，将滚轮送纱组件3复位，同时，滑动块311从滑槽601的低位向起始高位滑动，带动挑纱轮连动曲臂310动作，挑纱轮连动曲臂310另一端的第二轴承312向下移动，将挑纱轮连接臂308下压从而将挑纱轮307复位，位置传感器检测到挑纱轮307已复位后将信号传送给控制器，控制器控制直线模组2停止运动。
工作过程
初始状态，如图4所示，挑纱轮307处于起始位置，压紧轮驱动气缸305连杆处于伸出状态，压紧轮复位弹簧304处于释放状态，压紧轮302处于上位打开状态。纤维束4在出纱轮315和压紧轮302之间。如图5所示，滑动块311处于滑槽601的起始高位，但此时滑动块311与滑槽601有一定间距并未接触。挑纱轮弹簧309为拉伸状态，但挑纱轮连接臂308被第一轴承306及第二轴承312所限制，挑纱轮弹簧309并未将挑纱轮连接臂308拉动。纤维束4在出纱轮315和压紧轮302之间，纤维束4的纱头搭在挑纱轮307上自然下垂，此时第一轴承306处于高位。
如图6、图7所示，控制器控制压紧轮驱动气缸305的连杆缩回，通过压紧轮连接臂303带动压紧轮302向下移动，将纤维束4压紧在出纱轮315上，因压紧轮302固定连接第一轴承306，且第一轴承306与挑纱轮连接臂308滑动接触，所以压紧轮302向下移动的同时，拨动挑纱轮连接臂308向上运动，使挑纱轮弹簧309收缩，拉动挑纱轮连接臂308上挑，带动第二轴承312向上移动，而滑动块311向下移动与滑槽601接触，从而限制挑纱轮连接臂308继续上挑，此时挑纱轮307将纤维束4的纱头向上挑起，位置传感器检测到压紧轮302压紧到位，并将到位信号传送给控制器。
如图8所示，控制器接到压紧轮302到位信号后控制直线模组2移动，带动滚轮送纱组件3向缠绕工件5靠近，纤维束4一直被压紧轮302和出纱轮315夹持，也一并向缠绕工件5靠近，此时纤维束4的张力没有变化。随着滚轮送纱组件3向缠绕工件5靠近，如图9所示，滑动块311向滑槽601的低位滑动，第二轴承312继续向上移动，挑纱轮弹簧309得以继续拉动挑纱轮连接臂308上挑，带动挑纱轮307将纤维束4的纱头缠绕贴合在压纱轮313上，此时直线模组2已经移动到预定位置，控制器控制直线模组2停止运动。
如图10所示，直线模组2停止运动后，控制器控制压纱轮驱动气缸314连杆伸出，带动压纱轮313及纤维束4向缠绕工件5移动，以上动作将纤维束4的纱头压靠在缠绕工件5上。此时纤维束4具 有适合的缠绕张力。
如图11所示，在压纱轮313移动到位后，控制器控制缠绕工件5被驱动而进行轴向旋转，同时控制器控制出纱轮驱动电机317工作，通过两个齿轮316带动两个出纱轮315转动，保证出纱轮315的线速度与缠绕工件5环向纤维缠绕线速度一致，从而将具有适当缠绕张力的纤维束4顺利缠绕在缠绕工件5上，从而完成搭纱动作。
如图12所示，当完成若干圈缠绕后，纤维束4已经紧密环向缠绕在缠绕工件5上，已实现纤维的连续缠绕。控制器控制压纱轮驱动气缸314连杆缩回，带动压纱轮313复位。位置传感器检测到压纱轮313复位后将信号传送给控制器，控制器接到信号后控制压紧轮驱动气缸305连杆伸出，压紧轮复位弹簧304释放储能，将压紧轮302提升，解除对纤维束4的压紧，压紧轮302复位。
如图13所示，压紧轮302复位后，控制器控制自动搭纱装置远离纤维束4。自动搭纱装置回到起始位后，控制器控制直线模组2向初始位移动，带动滚轮送纱组件3复位，如图14所示，同时，滑动块311从滑槽601的低位向起始高位滑动，挑纱轮连动曲臂310一直带动第二轴承312向下移动，将挑纱轮连接臂308逐渐下压，最终挑纱轮连接臂308抵靠在第一轴承306上，挑纱轮307复位，位置传感器检测到挑纱轮307已复位后将信号传送给控制器，控制器控制直线模组2停止运动，挑纱轮弹簧309仍被拉伸，至此自动搭纱装置回到了初始状态，完成了一次全自动搭纱过程。
以上结合附图对本申请的实施方式作了详细说明，但本申请不限于所描述的实施方式。对于本领域的技术人员而言，在不脱离本申请原理和精神的情况下，对这些实施方式进行多种变化、修改、替换和变型，仍落入本申请的保护范围内。
