近几年,劳动力日趋紧张,为适应节省劳力的需求,一种柔性自动装配线应运而生。本文仅介绍一种节省劳力的关键措施——装配质量保证和紧固技术。为了实现高精度的装配,有效的方法是用视象传感器获取车身定位孔图象、间隙及表面高差等数据,经座标换算来修正装配位置,同时通过运用对最关键问题的着重处理和图象设计的方法实现了0.01mm 的高精度和100%的高识别率。由于采纳了圆形头部螺栓和机器人控制拧紧力的技术,高度紧固的可靠性达到了99.99%。目前,仅由少数人参与而机器人起重要作用的方式已被有效地应用在皇冠车的流水装配线上。
In recent years, the labor force has become increasingly tense. In order to meet the needs of saving labor, a flexible automatic assembly line came into being. This article describes only one key labor-saving measures - assembly quality assurance and fastening technology. In order to achieve high-precision assembly, the effective method is to use the image sensor to obtain the body positioning hole image, clearance and surface height difference data, the coordinate conversion to correct the assembly position, at the same time by applying the most critical issues and The method of image design achieves a high accuracy of 0.01 mm and a high recognition rate of 100%. Due to the adoption of round head bolts and robotic control of the tightening force technology, a high degree of fastening reliability reaches 99.99%. At present, only a few people involved in the robot plays an important role in the way has been effectively applied to the assembly line crown car.
