| 中文摘要: |
| 目的 为了提高包装机纠偏控制的精度和通用性，提出一种纠偏检测方法。方法 采用两路线阵CCD成像，并比较两者CCD信号，判断材料在工作过程中是否发生跑偏现象，然后通过控制器进行纠偏操作。结果 两路CCD灰度值显著变化的像元位置表明了带材的边缘位置，通过两像元的差值即可判断带材是否发生跑偏，方案可行。结论 相较于以往的CCD的检测方法，该方法稳定性和精度均有所提高，并且当材料的宽度在一定范围内变化时，纠偏装置仍可以工作，而不需要其他操作，通用性也有一定提高。 |
| 英文摘要: |
| The work aims to propose a correction detection method, in order to improve the correction control accuracy and versatility of the packaging machine. The CCD imaging of two linear arrays was used and the CCD signals of the two were compared to judge whether the deviation occurred when the materials were working. Then, the controller was used for correction operations. The pixel positions of the two CCD gray values with significant changes indicated the edge position of the strip. The difference between the two pixels could be used to judge whether the strip deviated and whether the scheme was feasible. Compared with the previous CCD detection method, the stability and accuracy of the proposed method are improved, and when the width of the material changes within a certain range, the correcting device can still work without other operations, and its versatility is also improved to some extent. |
