基于上述剔废设备，本申请实施例还提供一种电池极片的剔废控制方法，在此对电池极片的剔废控制方法进行说明。
请参见图2，是本申请实施例提供的电池极片的剔废控制方法的流程示意图。该电池极片的剔废控制方法应用于上述剔废设备，如图2所示，该电池极片的剔废控制方法包括至少包括如下步骤201至步骤204。
步骤201、在驱动机构驱动电池极片向剔废机构传输的过程中，若极片缺陷检测机构检测到所述电池极片为缺陷极片，则记录缺陷极片的第一距离，第一距离为由缺陷极片至剔废机构的距离。
步骤202、在缺陷极片由极片缺陷检测机构向剔废机构传输的过程中，获取驱动机构驱动缺陷极片运动的第二距离。
步骤203、基于第二距离更新缺陷极片的第一距离。
步骤204、在更新后的缺陷极片的第一距离满足预设条件的情况下，控制剔废机构将缺陷极片剔除。
本申请实施例中，在驱动机构驱动电池极片向剔废机构传输的过程中，在极片缺陷检测机构检测到的缺陷极片的情况下，可以记录该缺陷极片至剔废机构的第一距离，在缺陷极片由极片缺陷检测机构向剔废机构传输的过程中，获取驱动机构驱动缺陷极片运动的第二距离，并基于第二距离实时更新上述第一距离，使得在更新后的第一距离满足预设条件的情况下，控制剔废机构将缺陷极片剔除。如此，在电池极片在剔废设备中传输的过程中，可以控制剔废机构准确地剔除缺陷极片，从而避免将缺陷极片与隔膜进行复合，进而避免隔膜的浪费。
在上述步骤101中，在驱动机构驱动电池极片向剔废机构传输的过程中，极片缺陷检测机构可以检测经过的电池极片是否存在缺陷，在极片缺陷检测机构检测到电池极片存在缺陷的情况下，处理器可以确定经过极片缺陷检测机构的电池极片为缺陷极片，此时，处理器记录该缺陷极片至剔废机构的距离。
其中，由于上述极片缺陷检测机构与剔废机构的位置是固定不变，可以将极片缺陷检测机构与剔废机构之间的传输距离记录为上述第一距离，该传输距离为电池极片从极片缺陷检测机构运动至剔废机构的距离。
例如，处理器中预先设置有极片缺陷检测机构与裁切装置之间的传输距离L0，在极片缺陷检测机构检测到缺陷极片的情况下，处理器将L0记录为缺陷极片至剔废机构的距离(即上述第一距离)。
另外，上述极片缺陷检测机构可以检测经过的电池极片是否存在缺陷，可以是检测电池极片上是否出现折痕或者缺失等，在极片缺陷检测机构检测到电池极片存在折痕或者缺失等，那么处理器确定该电池极片为缺陷极片。
需要说明的是，上述处理器记录缺陷极片的第一距离，可以是将该缺陷极片的第一距离缓存至存储器中。例如，可以是处理器的缓存区中设置有用于缓存列表，且该处理器将缺陷极片的第一距离缓存于该缓存列表中，等等。
在上述步骤202中，在处理器记录上述缺陷极片的第一距离之后，在驱动机构驱动缺陷极片由极片缺陷检测机构向剔废机构传输的过程中，处理器可以获取驱动机构驱动缺陷极片运动的第二距离。
其中，上述处理器获取驱动机构驱动缺陷极片运动的第二距离，可以是处理器获取驱动机构的驱动速度以及计时时长，并将驱动速度与计时时长的乘积确定为上述第二距离。
需要说明的是，上述驱动速度为驱动机构驱动极片运动的速度，其可以根据驱动机构的主轴的转动速度以及主轴与极片之间的传动组件(如传动齿轮等)的传动参数(如齿轮直径等)等确定，而传动组件的参数通常是固定不变的，空置装置仅需获取驱动机构的主轴的转动速度即可计算得到上述驱动速度。
另外，上述处理器获取计时时长，可以是处理器中预设有计时器，在极片缺陷检测机构检测到缺陷极片时计时器开启计时。
在上述步骤203中，在处理器获取到上述第二距离之后，处理器可以基于获取到的第二距离，对上述缺陷极片的第一距离进行更新。
需要说明的是，上述基于第二距离对缺陷极片的第一距离进行更新，可以是将第一距离与第二距离的差值，作为更新后的第一距离。
在上述步骤204中，在上述处理器对上述第一距离更新后，上述 处理器可以判断更新后的第一距离是否满足预设条件，并在确定更新后的第一距离满足预设条件的情况下，控制剔废机构将缺陷极片剔除。
其中，上述判断更新后的第一距离是否满足预设条件，可以是判断更新后的第一距离是否小于或者等于零，在更新后的第一距离小于或者等于零的情况下，确定更新后的第一距离满足预设条件；反之，则不满足。
另外，上述控制剔废机构将缺陷极片剔除，可以是处理器确定更新后的第一距离满足上述预设条件的情况下，处理器生成裁切信号并发送至裁切装置，裁切装置响应于该裁切信号，在缺陷极片的切刀位裁切，实现将缺陷极片的切除，然后剔废装置将切除的缺陷极片收卷。
需要说明的是，上述切刀位为在上述缺陷极片进入至裁切装置所在位置之前，由切刀位检测机构通过检测电池极片的极耳或者处于相邻两个电池极片之间的切孔确定。
在一些实施方式中，上述若极片缺陷检测机构检测到所述电池极片为缺陷极片，则记录缺陷极片的第一距离，包括：
若极片缺陷检测机构检测到所述电池极片上设置有缺陷标识，则确定电池极片为缺陷极片，缺陷标识为设置于剔废设备上电池极片卷的首片电池极片上的标识；
记录缺陷极片的第一距离。
本实施方式中，可以通过在设置于剔废设备上电池极片卷电池极片上贴设缺陷标识，使得在剔废设备检测到该缺陷标识时，能够将被贴设有缺陷标识的电池极片作为缺陷极片进行剔除，从而可以根据用户的需要对电池极片卷中的电池极片进行剔除。
其中，上述贴设有上述缺陷标识的电池极片，可以是电池极片卷中的任意电池极片。具体地，可以是在将电池极片卷设置至剔废设备上时，在处于极片缺陷检测机构和电池极片卷之间的电池极片上贴设缺陷标识。
另外，上述缺陷极片可以是用于指示将贴设的电池极片进行剔除；或者，该缺陷标识也可以是用于指示将贴设的电池极片以及位于贴设 的电池极片之前的电池极片剔除。
示例性地，在将电池极片卷在剔废设备进行穿带的过程中，由于穿带后位于极片缺陷检测机构和裁切装置之间的电池极片的质量未知，为保证复合后的电池极片的质量，可以在处于极片缺陷检测机构和电池极片卷之间的首片电池极片上贴设缺陷标识。在极片缺陷检测机构检测到缺陷标识的情况下，处理器记录该首片电池极片的第一距离，并在该首片电池极片向裁切装置传输的过程中更新第一距离，直至该首片电池极片的第一距离小于或者等于零时，裁切装置在该首片电池极片的切刀位裁切该首片电池极片，且剔废装置将该裁切的首片电池极片以及位于该首片电池极片之前的电池极片收卷。
在一些实施方式中，上述若极片缺陷检测机构检测到所述电池极片为缺陷极片，则记录缺陷极片的第一距离，包括：
若极片缺陷检测机构检测到所述电池极片为缺陷极片，则在剔废设备的堆栈中增加与缺陷极片关联的元素，并将缺陷极片的第一距离，作为与缺陷极片关联的元素的元素值保存至堆栈中。
上述基于第二距离更新缺陷极片的第一距离，可以包括：
基于第二距离，对堆栈中每一元素的第一距离进行更新。
本实施方式中，通过将检测到的缺陷极片的第一距离，作为与缺陷极片关联的元素的元素值保存至堆栈中，且在更新时，基于第二距离同时对堆栈中每一元素的第一距离进行更新。由于堆栈遵循先进先出原则，且可以同时记录多个元素的元素值，使得可以避免记录的多个缺陷极片的第一距离出错，且更新时可以同时对多个缺陷极片的第一距离同时更新，节省计算资源。
示例性地，在剔废设备传输电池极片卷的电池极片的过程中，若极片缺陷检测机构检测到上述缺陷标识或者缺陷，处理器确定缺陷极片，并将该缺陷极片的第一距离L0保存到堆栈BadMark_DistanceArr[]栈顶，且堆栈保存的元素数BadMark_Num值加1；在上述驱动机构驱动电池极片传输的过程中，处理器获取驱动机构的驱动缺陷极片运动的第二距离，并对堆栈BadMark_DistanceArr[]中每个堆栈元素的元素值(即第一距离) BadMark_DistanceArr[Num]进行更新，其中，Num＝1，……，BadMark_Num。
在一些实施方式中，获取驱动机构驱动缺陷极片运动的第二距离，可以包括：
在第N个扫描周期到达的情况下，获取驱动机构在第N个扫描周期的第一反馈值，其中，N为大于1的整数，第一反馈值与驱动机构驱动电池极片运动的距离关联；
将第一反馈值与第二反馈值的差值确定为第二距离，第二反馈值为驱动机构在第N-1个扫描周期下的反馈值。
本实施方式中，通过处理器获取驱动机构在当前扫描周期(即第N个扫描周期)的第一反馈值和上一扫描周期(即第N-1个扫描周期)的第二反馈值，并将第一反馈值和第二反馈值的差值确定为第二距离，从而使得获取第二距离更准确，且方式更灵活。
其中，上述第一反馈值、第二反馈值与驱动机构驱动电池极片运动的距离关联。具体地，第一反馈值为在上述第N个扫描周期到达时驱动机构的传输距离，第二反馈值为上述第N-1个扫描周期到达时驱动机构的传输距离。
示例性地，上述对BadMark_DistanceArr[Num]进行更新，可以是通过如下公式(1)实现：
BadMark_DistanceArr[Num]＝BadMark_DistanceArr[Num]-IncEncoder  (1)
在公式(1)中，IncEncoder为PLC当前扫描周期记录的主驱编码器反馈值(即第一反馈值)与上个扫描周期记录的主驱编码器反馈值(即第二反馈值)的差值。
需要说明的是，上述各扫描周期的时长可以根据实际需要进行设定。例如，各扫描周期的时长可以是根据驱动机构的转轴速度设定，以在驱动机构当前的转轴速度下，在扫描周期内驱动机构的传输距离小于或者等于一个电池极片的宽度，等等。
本申请实施例中，在上述处理器可以通过堆栈记录各缺陷极片的第一距离并进行更新的情况下，当堆栈栈底元素更新后的第一距离满足预 设条件的情况下，处理器控制裁切装置将该元素对应的缺陷极片切除。
示例性地，在上述堆栈中记录有贴设有缺陷标识的首片电池极片的第一距离BadMark_DistanceArr[1]的情况下，在电池极片传输过程中，由于BadMark_DistanceArr[Num]的值不断更新即逐渐减小，当堆栈栈底元素的元素值BadMark_DistanceArr[1]小于或者等于0时，处理器确定贴设有缺陷标识的首片电池极片已到达裁切装置，裁切装置在该首片电池极片的切刀位切除该首片电池极片。
在一些实施方式中，方法还可以包括：
在堆栈中的元素小于或者等于零，且经过剔废机构的电池极片串的长度为预设电芯长度的情况下，控制剔废机构裁切电池极片串，其中，电池极片串用于与隔膜进行复合。
本实施方式中，在堆栈中的元素小于或者等于零，且经过剔废机构的电池极片串的长度为预设电芯长度的情况下，剔废机构还可以裁切电池极片串，以将裁切的电池极片串用于与隔膜复合，从而不仅可以实现对缺陷极片的裁切，还可以实现对正常极片的裁切。
其中，上述预设电芯长度可以根据实际需要进行设定。例如，在上述电池极片为负极极片的情况下，可以是设置上述预设电芯长度为一个负极极片的宽度；而在上述电池极片为正极极片的情况下，可以设置上述预设电芯长度为多个正极极片的宽度。
示例性地，若驱动机构驱动电池极片走过一个电芯长度(即预设电芯长度)，且上述堆栈BadMark_DistanceArr[]保存的元素数BadMark_Num值小于或者等于0，表示从极片缺陷检测机构到裁切装置的缺陷极片已驱出切刀位且被剔废装置收卷，此时从极片缺陷检测机构到裁切装置的电池极片无缺陷，则处理器可以控制裁切装置裁切该一个电芯长度的电池极片串。
在一些实施方式中，上述剔废设备还包括切刀位检测机构，切刀位检测机构设置于极片缺陷检测机构和剔废机构之间。
在更新后的缺陷极片的第一距离满足预设条件的情况下，控制剔废机构将缺陷极片剔除之前，还可以包括：
基于切刀位信号，将更新后的缺陷极片的第一距离更新为第三距离，其中，切刀位信号为切刀位检测机构基于更新后的缺陷极片的第一距离，检测到缺陷极片的切刀位置时生成的信号；第三距离为切刀位检测机构与剔废机构之间的距离。
上述控制剔废机构将缺陷极片剔除，可以包括：
控制剔废机构在切刀位置切除缺陷极片，以剔除缺陷极片。
本实施方式中，通过在基于切刀位检测机构在检测到切刀位置时生成的切刀位信号，将更新后的缺陷极片的第一距离更新为第三距离，从而可以避免因扫描周期延迟造成更新后的第一距离存在误差的影响，提高电池极片裁切的精度。
需要说明的是，上述第三距离为切刀位检测机构与剔废机构之间的距离，可以是切刀位检测机构与上述裁切装置之间的距离。
本申请实施例中，在上述缺陷极片的切刀位置到达裁切装置时，上述处理器控制裁切装置切除缺陷极片，可以是处理器控制主驱机构停机，使得切刀位置到达裁切装置时停止传输缺陷极片，且裁切装置在主驱机构停机的情况下切除缺陷极片，且剔废装置完成对缺陷极片的收卷，并在完成收卷后，裁切装置和剔废装置归位。
在一些实施方式中，在驱动机构驱动电池极片向剔废机构传输过程中，驱动机构与剔废机构耦合。
控制剔废机构在切刀位置切除缺陷极片，以剔除缺陷极片，可以包括：
在确定缺陷极片的切刀位置到达剔废机构的情况下，将驱动机构与剔废机构解耦，并控制驱动机构停止驱动缺陷极片传输，以及控制剔废机构在切刀位置切除缺陷极片，以剔除缺陷极片。
本实施方式中，在驱动机构与剔废机构耦合且传输电池极片的过程中，在缺陷极片的切刀位置达到裁切设备的情况下，及时控制驱动机构与剔废机构解耦，实现驱动机构停止驱动缺陷极片传输，并控制裁切设备在切刀位置切除缺陷极片并剔除，从而可以实现对剔废设备的可控停机，保证电池极片复合生产的连续性，提升生产效率。
需要说明的是，在上述剔废机构完成对缺陷极片的剔除后，驱动机构与剔废机构可以重新进行耦合，以保证电池极片的传输。
