随着自动控制与电子技术的迅速发展,我厂产品中印刷线路板的品种与数量逐年增加,而且是多品种、小批量的重复生产。长期以来,印刷线路板焊点孔的加工工艺十分落后,全靠工人在台钻上逐个钻孔,劳动强度大,生产效率低,质量不稳定,而且钻削产生的玻璃纤维粉尘严重危害工人身体健康。为了改变这种落后面貌,实现半自动化,我厂工人大学二
With the rapid development of automatic control and electronic technology, the varieties and quantities of printed circuit boards in our factory products have been increasing year by year, and are repeated production with many varieties and small quantities. For a long time, PCB solder hole processing process is very backward, thanks to the workers in the drilling rig one by one drilling, labor-intensive, low productivity, quality is unstable, and the drilling of glass fiber dust seriously endanger the workers body health. In order to change this backward outlook, to achieve semi-automation, I plant workers University two
