目的 解决闭口铁桶封口设备存在的寻口速度慢、 封口效率低和设备可靠性差的问题。方法 设计了一种封口设备， 采用视觉寻口技术实现寻口操作， 同时将旋盖和压盖等2道工序设计在同一工位完成。结果 寻口快速准确， 并且只需对桶口定位1次， 即可完成旋盖和压盖等2道工序。结论 该设备经实际应用， 工作可靠， 封口效率高。

The aim of this study was to solve the existing problems of sealing device for mouth-closed iron drums such as slow searching speed, low sealing efficiency and poor reliability. A sealing device was designed, which fixed sprue using visual positioning technique, and the two processes of cap screwing and cap pressing were simultaneously finished at the same work station. The mouth was located quickly and precisely. Only one localization was required for the completion of the two procedures of cap screwing and cap pressing. The practical application showed that the device was reliable and had high sealing efficiency.
