具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本发明，并不用于限定本发明。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书、权利要求书或上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
目前卷绕机在运行中时，会受到多方面因素的共同影响，例如光电位置与响应时间、电机响应与不同步、极耳区间来料不稳定、辊送压力和摩擦系数不匹配等，这些因素都会导致极耳边距的稳定性受到影响，直接或者间接导致卷绕机在生产过程中出现偶发性或者批量性电芯品质不良，从而降低设备生产优率。
为解决上述存在的问题，本发明实施例提供了一种极耳边距控制方法、装置、控制器以及存储介质，该极耳边距控制方法包括以下步骤：获取料带的中断信号，中断信号表征检测到设置在料带上的首极耳；根据中断信号控制输送模块按设定距离运动获得首极耳移动的预设中断距离；控制卷针模块启动，并获取卷针模块的主轴追踪距离数据；根据主轴追踪距离数据确定输送模块与预设置的电子凸轮的耦合切入参数信息；根据耦合切入参数信息对输送模块和电子凸轮进行耦合处理；控制输送模块将首极耳辊送入卷针模块，并通过输送模块和卷针模块对料带进行预卷绕处理；当根据预卷绕处理所获取的预卷绕参数满足预设条件时，停止输送模块运动，并控制卷针模块对料带进行卷绕处理。在本实施例的技术方案中，通过检测模块对首极耳进行感应并根据所感应到的中断信号控制输送模块使得首极耳移动中断距离，能减少输送模块在送片过程中因料线或者机械结构所引起的误差，并且通过输送模块和电子凸轮耦合的方案能够在不影响边距稳定性的情况下提高效率，即能够避免生产过程中的定位误差，且提高设备生产优率和效率。
下面结合附图，对本发明实施例作进一步阐述。
如图1所示，图1是本发明一个实施例提供的极耳边距控制设备的示意图； 本发明实施例的极耳边距控制设备包括检测模块110、输送模块120、卷针模块130和控制器(图中未示出)，控制器(图中未示出)分别与检测模块110、输送模块120和卷针模块130通信连接，其中，输送模块120分为阳极极耳输送模块和阴极极耳输送模块，阳极极耳输送模块和阴极极耳输送模块均包括辊送驱动辊121和直拉纠偏夹紧辊122。其中，输送模块120中的辊送驱动辊121为定辊，输送模块120中的直拉纠偏夹紧辊122为动辊，输送模块120用于将料带140上的首极耳辊送至卷针模块130上，卷针模块130用于将料带140卷绕成电芯。可以理解的，在料带140上设置有多个极耳组，一个极耳组包括首极耳、多个中间极耳和尾极耳，其中首极耳指的是在本工作流程中所检测到的第一极耳，可以是极片头部的第一个极耳，可以是第二个极耳，也可以是第三个极耳，本实施例对其不作具体限定，首极耳和尾极耳用于作为裁切的标识。
需要说明的是，输送模块120可以是辊送模块，也可以是其他能够实现将料带进行传输至卷针模块130的设备，本实施例对其不作具体限定。
需要说明的是，检测模块110可以是光电检测模块，也可以是其他能够实现检测到料带上的极耳的设备，本实施例对其不作具体限定。
可以理解的，本实施例的极耳边距控制方法除了可以应用于极耳边距控制设备中，还可以应用于其他设备中，本实施例对其不作具体限定。
基于上述于极耳边距控制设备，下面提出本发明的极耳边距控制方法的各个实施例。
参照图2，图2为本发明一个实施例提供的极耳边距控制方法的流程图，本发明实施例的控制方法可以包括但不限于包括步骤S100、步骤S200、步骤S300、步骤S400和步骤S500。
步骤S100，通过检测模块获取中断信号，中断信号表征检测到设置在料带上的首极耳。
具体地，在完成上一个电芯完成制作后，控制检测模块启动定位检测处理，同时辊送模块以预设的第一速度进行工作，可以理解的是，在定位检测的过程中为了能够提高检测的精确度，第一速度不会设定太快。当检测模块检测到首极耳时，检测模块会生成中断信号，并向控制器发送中断信号，此时，控制器会接收到中断信号。
在一实施例中，控制检测模块启动定位检测处理，同时辊送模块以预设的第 一速度进行工作，如果在设定的有效的检测窗口范围内能够获取中断信号后，其中，检测窗口范围为在定位检测处理的过程中所预设的一个检测范围，执行设定的预设的固定的中断距离；若无中断信号或中断信号不在检测窗口范围内则判定为错误，无法检测到首极耳，那么可以认为此料带已经没有极耳或者料带设置上存在其他问题，那么则停止工作，无需要继续执行后续流程。
在一实施例中，检测模块在PLC控制模式受到其扫描周期长的影响，普通IO通道信号固定刷新周期较长，而采用高速探针的驱动器控制模式，其扫描周期极短，响应极快可以提升响应时间；针对梯形极耳，将检测模块安装在极耳根部高度1/3处可有效减小因为梯形极耳与料线偏移所造成的定位误差，其中，料线为在纠偏设定的准确的情况下极耳的位置。
步骤S200，根据中断信号控制输送模块使得首极耳移动预设的中断距离。
具体地，控制器在接收到中断信号之后，会立即根据中断信号对辊送模块进行控制，使得首极耳从检测位置开始移动预设的中断距离，达到中断距离结束位置。
在一实施例中，检测模块设置在辊送模块的料带辊送方向的后方，当控制器接收到光电模块发出的中断信号之后，根据中断信号对辊送模块进行控制，使得首极耳从检测位置开始移动预设的中断距离，当首极耳移动中断距离之后，料带从辊送模块的料带辊送方向的后方移动至辊送模块的料带辊送方向的前方。相比通过直接走绝对定位，在料带裁切后送片位置不稳定，对极耳位置无法进行有效监控与闭环控制。而本实施例中，通过增加检测模块检测首极耳，检测到首极耳后走定长可以消除送片过程中因料线或者机械结构所引起的误差。
在一实施例中，参照图3，在接收到中断信号之后，控制器可以控制辊送模块从第一速度(定位速度)提升至第二速度(中断速度)，并通过以第二速度(中断速度)运行的辊送模块带动首极耳移动预设的中断距离后，控制辊送模块从第二速度逐渐减速至停止，提高中断距离间的速度能够有效提高效率。其中，EXCUTE表征断定位处理过程，INFEED表征对辊送模块的速度进行调整的过程。
需要说明的是，第一速度和第二速度根据实际生产时间和生产工艺等方面进行设置，本实施例对其不作具体限定。例如，以第一速度去找中断信号时，如果检测的距离较长，可以将一速度设置较大的速度；如果中断距离较长，则可以将 第二速度设置为更大的速度，第二速度是可以根据中断距离而定的，第二速度与第一速度没有必然的关系，可以根据各自需要走的距离进行设定。
在一是实施例中，在接收到中断信号之后，控制器可以不对辊送模块的速度进行控制，使得辊送模块保持第一速度运行，带动首极耳移动预设的中断距离，首极耳指的是触发本次中断信号的极耳，可以是极片头部的第一个极耳，可以是第二个极耳，也可以是第三个极耳，本实施例对其不作具体限定。
需要说明的是，中断距离根据实际工艺要求进行设置，本实施例对其不作具体限定。
步骤S300，控制卷针模块启动，并获取卷针模块的主轴追踪距离数据。
具体地，可以对每根卷针模块进行单独设置参数，那么控制器会获取到卷针设置参数，然后根据卷针设置参数建立转盘中的卷针设置参数对应的卷针模块的追踪数据库，其中所建立的追踪数据库用于获取卷针模块的主轴追踪距离数据。在完成中断定位处理后，控制卷针模块启动，然后通过追踪数据库获取卷针模块的主轴追踪距离数据。
需要说明的是，卷针设置参数可以是包括卷针边距补偿值、阴极(或者阳极)预辊长度、阴极(或者阳极)预辊速度、辊送同步比率、检测起点、检测终端、阴极(或者阳极)在定位模式下感应到信号走定长等数据，本实施例对其不作具体限定，可以根据控制的要求进行设置。
需要说明的是，主轴追踪距离数据为卷针设置参数所得到的在实际工作过程中工作数据。
步骤S400，根据主轴追踪距离数据确定输送模块与电子凸轮的耦合切入参数信息。
具体地，获取卷针模块的主轴追踪距离数据后，可以根据主轴追踪距离数据和辊送模块的运行情况以及电子凸轮确定辊送模块与电子凸轮进行耦合所需要的耦合切入参数信息，该耦合切入参数信息用于使得输送模块和卷针达到速度和位置进行同步。
需要说明的是，电子凸轮是预设定的电子凸轮，该电子凸轮用于同步卷针模块和辊送模块的速度和位置，具体的电子凸轮的曲线根据实际情况设置，本实施例对其不作具体限定。
步骤S500，根据耦合切入参数信息对输送模块和电子凸轮进行耦合处理。
具体地，采用辊送模块耦合电子凸轮的技术方案，相比于并膜辊送的技术方案效率更高，而且不受电芯卷绕工艺限制，再而并膜辊送的方案虽然边距稳定，但是电芯头部X-Ray极差。辊送模块耦合电子凸轮的技术方案，通过辊送耦合凸轮同步的技术方案，可在不影响边距稳定性的情况下提高效率与头部X-Ray，辊送耦合凸轮同步的技术方案是电子凸轮结合主轴偏置方案，相当于提前耦合，例如：该方案可以通过在触摸屏设置3个电子凸轮坐标参数，计算出设定好的辊送电子凸轮轨迹，在卷绕启动同时辊送电机进行电子凸轮耦合，可以达到同步耦合的目的。
步骤S600，通过输送模块将首极耳辊送入卷针模块，并通过输送模块和卷针模块对料带进行预卷绕处理。
具体地，在完成辊送模块和电子凸轮的耦合处理之后，通过辊送模块将首极耳辊送入卷针模块的合适位置，然后通过辊送模块和卷针模块对料带进行预卷绕处理，能够使得料带在进入卷针模块后能够平稳过渡，减少出现偏移的问题，提高准确度。
步骤S700，当根据预卷绕处理所获取的预卷绕参数满足预设条件时，停止输送模块运动，并通过卷针模块对料带进行卷绕处理。
具体地，在预卷绕处理的过程中，获取预卷绕参数，当预卷绕参数大于预设条件时，输送模块和卷针模块达到速度和位置同步后输送模块停止辊送，完成预卷绕处理，然后通过卷针模块对料带进行后续的卷绕处理，最后得到目标电芯。
需要说明的是，预设条件包括在预卷绕处理的过程中料带卷绕达到预设圈数，或者，在预卷绕处理的过程中卷针模块达到预设旋转角度。
需要说明的是，预设圈数和预设旋转角度根据实际工艺要求进行设置，本实施例对其不作具体限定。
在一实施例中，参照图4，当预卷绕参数大于预设条件时，输送模块和卷针模块达到速度和位置同步后输送模块停止辊送，完成预卷绕处理，控制卷针模块从第三速度(预卷速度)提高至第四速度(卷绕速度)，使得卷针模块以第四速度(卷绕速度)对料带进行卷绕处理，在完成卷绕处理后，控制卷针模块从第四速度(卷绕速度)下降至第五速度(裁切速度)，并控制裁切模块对料带进行裁切处理，裁切处理完之后控制卷针模块停止。其中，EXCUTE表征卷针模块卷绕料带的过程,CAMIN表征输送模块和电子凸轮进行耦合处理的过程，CAMOUT 表征输送模块和电子凸轮进行耦合处理完成之后分别调整输送模块和卷针模块的处理过程。
需要说明的是，第三速度、第四速度和第五速度根据实际生产时间和生产工艺等方面进行设置，本实施例对其不作具体限定。
在一实施例中，在完成上一个电芯完成制作后，控制检测模块启动定位检测处理，同时辊送模块以预设的第一速度进行工作，当检测模块检测到首极耳时，检测模块会生成中断信号，并向控制器发送中断信号，此时，控制器会接收到中断信号,然后控制器会根据中断信号对辊送模块进行控制，使得首极耳从检测位置开始移动预设的中断距离，控制辊送模块停止，接着控制卷针模块启动，然后通过追踪数据库获取卷针模块的主轴追踪距离数据，并根据主轴追踪距离数据确定辊送模块与电子凸轮的耦合切入参数信息，然后根据耦合切入参数信息对辊送模块和电子凸轮进行耦合处理，在完成辊送模块和电子凸轮的耦合处理完毕之后，通过辊送模块将首极耳辊送入卷针模块的合适位置，然后通过辊送模块和卷针模块对料带进行预卷绕处理，在预卷绕处理的过程中，获取预卷绕参数，当预卷绕参数大于预设条件时，辊送模块和卷针达到速度和位置同步后辊送模块停止辊送，完成预卷绕处理，然后通过卷针模块对料带进行后续的卷绕处理，最后得到目标电芯。在本实施例的技术方案中，通过检测模块对首极耳进行感应并使得首极耳移动中断距离能够消除辊送模块在送片过程中因料线或者机械结构所引起的误差，并且通过辊送模块和电子凸轮耦合的方案能够在不影响边距稳定性的情况下提高效率，即能够避免生产过程中的定位误差，且提高设备生产优率和效率。
在一实施例中，参照图5，图5为本发明一个实施例提供的极耳边距控制方法中的根据响应误差信息调整参数的流程图。在步骤S700之后，极耳边距控制方法还包括但不限于步骤S510和步骤S520。
步骤S510，获取辊送模块与预设辊送模块的响应误差信息；
步骤S520，若响应误差信息大于预设误差要求时，对辊送模块增加或减少辊送模块的惯量比参数值和/或机械刚性参数值。
在一实施例中，当定位检测处理完成时如果辊送模块的响应达不到要求(正常需要将响应降低到10ms以内)，容易丢失辊送模块同步精度，而且容易受到摩擦力大小关系的影响，导致原先定位好的位置发生偏移，从而影响整个电芯极耳 边距的稳定性。所以在辊送模块不震荡、不尖叫的前提下，可适当加大伺服的惯量比参数值和/或机械刚性参数值，以提高抗外界力干扰的能力。
在一实施例中，参照图6，图6为本发明一个实施例提供的极耳边距控制方法中的首极耳的定位检测的流程图。在步骤S700之后，极耳边距控制方法还包括但不限于步骤S610和步骤S620。

步骤S620，若位置波动信息大于预设波动范围，控制报警模块发出报警信息，并根据报警信息控制辊送模块和卷针模块停止工作。
在一实施例中，通过首极耳定位误差波动程序，监控每次首极耳的定位信息与预设首极耳定位信息所比较得到的位置波动信息的情况,当首极耳的位置波动信息连续或者波动较大时，及时控制报警模块发出报警信息，并根据报警信息控制辊送模块和卷针模块停止工作，以提示用户检查来料或者对参数进行修改调节。
