如图1所示，作为本申请的一种优选实施例，第一识别装置3为工业相机，工业相机数量为两个；工业相机一一对应设置有转动装置2；第二识别装置4为扫描器，扫描器数量为一个；扫描器对应设置有转动装置2；转动装置2用于使柱状物6旋转固定角度，所述固定角度为预设的固定数值。As shown in Figure 1, as a preferred embodiment of the present application, the
示例性的，在本实施例中，工业相机的数量为两个，扫描器的数量为一个，三者呈扇形依次布置在转动盘11的一侧，主动轮21的数量为三个，与工业相机和扫描器一一对应，扇形的弧度与转动盘11的弧度相同，相互之间等距，主动轮21一一对应的转动盘6上设置有放置槽12，放置槽12均匀布置在转动盘11的外圈上，放置槽12的直径较柱状物6的大，柱状物6放置在放置槽12内，可以滑动。条码识别装置工作时，柱状物6进入工业相机的识别区域对应的主动轮21和从动轮23之间，此时转动盘11间歇的停止旋转，柱状物6在每个主动轮21和从动轮23之间停留的间隔时长相同，工业相机持续工作，实时的判断识别区域内条码是否正对工业相机，并将反馈信息发送给伺服电机22，伺服电机22依此判断是否需要带动柱状物6旋转。比如，柱状物6在被主动轮和从动轮夹持并被第一个工业相机识别时，存在两种情况，一种情况是：柱状物6条码处在正对工业相机的位置，此时无需旋转柱状物6；一种情况是：柱状物6条码不处在正对工业相机的位置，此时需要转送柱状物6，但又存在两种情况，一种情况是：在间隔时长内，柱状物6上条码可以被转动到正对工业相机的位置，一种情况是：在间隔时长内，柱状物6经过转动后其上条码仍然无法正对工业相机。因此，柱状物6在第一个工业相机识别后，若柱状物6上的条码已正对工业相机，则柱状物6被第二个工业相机识别时，柱状物6无需旋转；若柱状物6上的条码仍未正对工业相机，则柱状物6被第二个工业相机识别时，柱状物6被转动装置转动，使条码正对工业相机。柱状物6经过两个主动轮21和从动轮23之间后，条码已在正对工业相机的位置，然后进入扫描器识别区域对应的主动轮21和从动轮23之间，待扫描器识别条码特征信息后，主动轮21带动柱状物6旋转固定的角度，所述固定角度为预设的固定数值，将所有经过条码识别装置的柱状物上条码面对的方向统一，便于下一工序的检测。Exemplarily, in this embodiment, the number of industrial cameras is two, the number of scanners is one, and the three are arranged in a fan shape on one side of the
设置两个工业相机并对应设置有两个转动装置的目的是，避免通过一个转动装置转动主动轮时，在一个主动轮21和从动轮23之间内柱状物停留的间隔时长无法使柱状物6上条码通过主动轮21旋转到正对工业相机的位置。工业相机的数量与柱状物停留的间隔时长相关，本实施例中，间隔时长内，柱状物旋转的最大角度为180°，则工业相机设置有两个，可以理解的，间隔时长内，柱状物旋转的最大角度为120°，则工业相机设置有3个。通过设置两个工业相机以及两个转动装置，使送料装置和转动装置在时间上的配合更加合理，两者之间的配合工作更加协调，使整个视觉识别装置的工作效率更高。The purpose of arranging two industrial cameras and correspondingly having two rotating devices is to avoid that when the driving wheel is rotated by a rotating device, the length of the interval between the stay of the column between a
转动装置2是这样工作的：动力源6在驱动转动盘11间歇旋转的同时，通过凸轮28、第三滑动块26、第二滑动块25使第一滑动块24间歇的移动，柱状物6停留在主动轮21和从动轮23之间的同时，第一滑动块24推动柱状物6与主动轮抵接，当柱状物6需要移动时，第一滑动块24与柱状物6分离。示例性的，凸轮28在动力源6的驱动下转动，当凸轮28的凸缘推动第三滑动块26向上移动，第三滑动块26上第三滑动槽31配合第二转动轮30滑动，第二转动轮25被第三滑动槽30向前推动同时带动第二滑动块25向前，第二滑动块25上第二滑动槽32向前，第一转动轮33被第二滑动槽32向前推动同时带动第一滑动块24向转动盘11径向方向移动，从而第一滑动块24与柱状物6分离。转动装置2和送料装置1通过同一动力源驱动，并使送料装置1和推拉装置之间以固定的时间间隔配合工作，来对柱状物6的条码进行逐一识别。The rotating device 2 works like this: when the
