用于机器人定位的直线运动轨迹

2019-04-09

通过丽莎艾特尔 •机器人定位轨道可以增加制造空间的灵活性,但必须快速,准确且安全才能真正有用。在这里,我们来看看提供的驱动器。

Robot positioning systems are long tracks in warehouse, aerospace, and automotive facilities to let one robot perform multiple tasks. Also called robot-transfer units or RTUs, these motion designs are increasingly common for assembly, large-scale welding, and warehousing.

与机器人固定在地板上的典型设置相比,RTU将机器人移动到工作单元和工厂,并在工作站之间穿梭。 RTU的最佳设置是刚刚构建的或者可以将流程和相关机器直接放在一起的设置。在RTU移动六轴机器人的情况下,线性轨道有时也称为第七轴(或者当机器人本身具有七个自由度时,不太常见,即第八轴)。当这些轨道是框架的一部分时,包括机器人悬挂的框架,它们就是龙门架。

No matter the robot or track morphology, the point of the extra axis is to add translational motion. This either extends the work envelope or lets a robot transport work-pieces or tools. In some arrangements, the former lets a robot tend multiple machines or pick pallets from rows, or machine very large components. For the latter, common applications are packing, welding, plasma-arc cutting, and other mechanical tasks.

这里我们关注RTU的驱动选项。但请注意,工程师还必须在一系列导轨和轴承之间做出决定(通常采用凸轮从动件或型材导轨的形式)。
