A New Trend in Large Component Manufacturing

The need to manufacture large parts in stringent requirements is growing across many industries, and traditional production solutions are often inflexible, with generally high production costs and cycle times. Large, heavy shop-level machines and equipment are often used, resulting in high manufacturing costs. The large, specialized equipment is limited in terms of versatility. In order to meet the demand for shorter development cycles, lower costs and higher efficiency for large workpieces, there is an urgent need for multifunctional systems that can continuously adapt to technological advances.

Universal Mobile Platform

The mobile platform is connected to the universal AGV/AMR at the bottom to realize autonomous movement. A general-purpose industrial robot is installed on top to automatically complete all kinds of operations.

A mobile platform equipped with an industrial robot allows for more efficient handling of large parts in large area. It can be equipped with different brands of industrial robots. The low coast and lightweight solution does not require special foundations. Multiple mobile platforms work in parallel to process different parts of the same large workpiece, significantly increasing productivity.

双重定位方法

大型工件作业往往伴随着重载荷任务,比如加工应用、握持重型抓具或搬运大重量零件,重载作用力会导致机器人TCP(工具中心点)偏离目标路径,这些偏差无法被机器人自身的电机编码器所测得,意味着标定和内部控制系统不能应对外部影响造成的误差。在累加移动定位误差后,机器人的系统的基准定位和更加成为一个重要瓶颈。

静态动态双重定位方法,确定移动平台及机器人相对于加工工件的位置,提高机器人操作的绝对精度,免受未计入的负载、持续加工力、温度波动、标定或测量误差等外部影响。

静态定位

每次停靠在新的工作位置,机器人准备开始作业之前,系统首先要校准机器人的基准位置。此时激光跟踪仪检测机器人底座上的反射球座,获取机器人的实际位置,对机器人程序进行补偿。

动态定位

机器人关节臂握持抓具按照程序移动到每个关键位置时,立体相机对专用抓具转接头上的数个回射标记进行拍摄识别,确定机器人末端执行器的位置/朝向以及与目标位姿的偏差。动态校正功能独立于机器人、负载和环境参数(例如温度)的影响,在整个工作空间中实现优于大部分关节机器人重复精度的定位精度,特别适合于大型零件高精度作业需求。
