摘要

SMD组件的放置通常由笛卡尔型机器人执行，这是一项被称为拾取放置(P&P)的任务。小型选择性合规铰接式机械臂(SCARA)机器人也越来越受欢迎，因为它们的快速和准确的性能。本文描述了将精益机器人微制造(LRM)框架应用于大型10kg有效载荷的工业SCARA PCB组装机器人。LRM框架指导了PCB装配过程的精度评估，并提供了放置精度和成品率的预测。我们通过实验评估了系统的可重复性，以及组装过程中产生的集体误差。结果表明，在不采用闭环视觉伺服的情况下，P&P任务可以达到200微米的装配公差要求，从而大大降低了系统的复杂性和装配时间。

Precision Evaluation of Large Payload SCARA Robot for PCB Assembly

The placement of SMD components is usually performed with Cartesian type robots, a task known as pick-and-place (P&P). Small Selective Compliance Articulated Robot Arm (SCARA) robots are also growing in popularity for this use because of their quick and accurate performance. This paper describes the use of the Lean Robotic Micromanufacturing (LRM) framework applied on a large, 10kg payload, industrial SCARA robot for PCB assembly. The LRM framework guided the precision evaluation of the PCB assembly process and provided a prediction of the placement precision and yield. We experimentally evaluated the repeatability of the system, as well as the resulting collective errors during the assembly. Results confirm that the P&P task can achieve the required assembly tolerance of 200 microns without employing closed-loop visual servoing, therefore considerably decreasing the system complexity and assembly time.
