具体地，移送装置50包括动力机构51、安装板52和拾取单元；拾取单元包括至少两个真空吸盘53；至少两个真空吸盘53分别安装在安装板52上，并可彼此靠近或彼此远离；此处需要说明的是，使用时，该真空吸盘53通过软管与外部真空泵连通，并通过外部真空泵的抽气或放气，而实现对电芯70的拾取或释放；真空吸盘53对应设置有锁定结构60，锁定结构60用于将对应真空吸盘53固定在安装板52上；动力机构51用于带动安装板52运动。使用时，根据待电芯70的尺寸调整至少两个该真空吸盘53之间的距离，使至少两个真空吸盘53其彼此靠近或彼此远离，并在调整至合适位置之后，采用锁定结构60将对应的真空吸盘53锁定在安装板52上，通过动力机构51带动安装板52运动，进而联动真空吸盘53运动，真空吸盘53将电芯70吸取，之后在动力机构51而实现电芯70的移送，并移送到位时，吸盘释放电芯70，完整电芯70的移送；上述过程中，通过真空吸盘53拾取电芯70，相对夹取的方式，可避免对电芯70的结构造成破坏；再者，通过调整至少两个该真空吸盘53之间的距离，可适用于不同尺寸的电芯70，进而本电芯检测设备的通用性。
上述的锁定结构60可采用以下方式实施，实施例一：锁定结构60包括插销，真空吸盘53上开设第一插孔，安装板52开设多个第二插孔；如此，通过插销穿过第一插孔和其中一个第二插孔即可实现真空吸盘53的锁定；但是，上述结构需要在真空吸盘53上开设第一插孔，容易对真空吸盘53造成破坏；实施例二：该锁定结构60包括固定在真空吸盘53上的磁铁块以及固定在安装板52上的磁铁条，如此，通过磁铁块与磁铁条的相互吸附，实现真空吸盘53的锁定；但是，上述结构在使用过久时，磁铁块或磁铁条易出现消磁现象，而造成对真空吸盘53失去锁定效果。
优选地，安装板52上开设有与至少两条真空吸盘53一一对应设置的至少两个调节槽521；锁定结构60包括调节螺杆61和两个锁定螺母62；调节螺杆61的杆部活动穿过对应调节槽521，并与安装板52固接；两个锁定螺母62分置于安装板52的上下两侧，并分别螺接在调节螺杆61的杆部上；如此，通过旋动两个锁定螺母62使两个锁定螺母62远离安装板52，此时真空吸盘53可相对安装板52移动；之后通过旋动两个锁定螺母62使两个锁定螺母62靠近安装板52，在锁定螺母62抵于安装板52上，两锁定螺母62配合夹紧安装板52，此时在锁定螺母62与安装板52之间摩擦力的作用下实现将真空吸盘53固定在安装板52上；该结构无需在真空吸盘53上开设插孔，可避免对真空吸盘53的破坏；再者，可避免因使用时间过长而失去对真空吸盘53的锁定效果。
具体地，至少两条调节槽521绕安装板52的中心依次间隔排布。
进一步地，动力机构51包括底座511、第一机械臂512、第一旋转结构、第二机械臂513、第二旋转结构、第三机械臂514、第三旋转结构和升降机构；第一机械臂512其中一端安装在底座511上，并可相对底座511在水平面转动；第一旋转结构用于带动第一机械臂512转动；第二机械臂513的其中一端安装在第一机械臂512的另一端，并可相对第一机械臂512在水平面转动；第二旋转结构安装在第一机械臂512上，并用于带动第二机械臂513转动；第三机械臂514安装在第二机械臂513的另一端，并可相对第二机械臂513在水平面转动；第三机械臂514还可相对第二机械臂513升降；第三旋转结构安装在第二机械臂513上，并用于带动第三机械臂514转动；升降机构安装在第二机械臂513上，并用于带动第三机械臂514升降；安装板52安装在第三机械臂514上。
在上述结构基础上，使用时，通过第一旋转电机带动第一机械臂512、第二旋转电机带动第二机械臂513，且第三旋转电机带动第三机械臂514，实现带动 安装板52的旋转，进而使安装板52联动真空吸盘53至带拾取电芯70正上方位置，之后升降机构带动第三机械臂514下降，而使真空吸盘53靠近电芯70，之后实现拾取；该动力机构51通过底座511、第一机械臂512、第一旋转机构、第二机械臂513、第二旋转机构、第三机械臂514、第三旋转机构的配合，提高了旋转角度自由度，实现多角度的转动，使用更灵活；再者，配合升降机构，确保真空吸盘53对电芯70的拾取。
具体地，该第一旋转机构为第一旋转电机，第一旋转电机的输出轴与第一机械臂512传动连接；该第一旋转机构还可为旋转液缸或者旋转中空平台等等。
进一步地，该第二旋转机构也可为旋转电机、旋转液缸或者旋转中空平台等等。
具体地，该升降机构为气缸，气缸的缸体固定在第二旋转臂上，气缸的伸缩杆与第三机械臂514固定连接；如此，通过气缸的伸缩杆的伸缩，实现带动第三机械臂514的升降；该升降机构还可为直线电机，或者丝杆与丝杆螺母配合的结构。
更具体地，第三旋转机构为第二旋转电机，第二旋转电机的机体固定在第二旋转臂上，第二旋转电机的输出轴与气缸的缸体固定连接；如此，通过第二旋转电机带动气缸旋转，进而联动第三旋转臂转动；该第三旋转机构还可旋转液缸或者旋转中空平台等等。
