| 目的 为了实现0402元件包装纸带冲孔尺寸与毛边长度的检测，以便作为冲压制品的品质检验及模具观测判断和调整的依据，构建一台影像检测系统。方法 采用CCD拾取纸带影像并配合电机带动平台移动，使用二值化算法及形态学内插算法处理后，测量出最长的毛边尺寸，采用LabVIEW编程控制影像的拾取、处理，并通过人机界面显示其尺寸或毛边、长度平均值、3个标准差（3σ）、最大/最小值与差值、综合制程能力指数等，以确认产品的品质。结果 实验结果显示，影像检测系统每次测量10片纸带，每片测量需64 s，最大定位误差为0.005 mm，误差百分比最大为3.93%，将毛边检测中发现的纸带毛边位置及长度与国家标准相对比，可作为模具调整或更换的依据。结论 此影像检测系统可替代人工测量，降低了人为测量误差，并节省了时间，提高了生产效能。 |

| The work aims to construct an image detection system to detect the punching size and edge length of 0402 component packaging paper tape, which is regarded as the basis for quality inspection of stamping products and for observation, judgment and adjustment of mold. Firstly, CCD was used to pick up paper tape image and cooperate with motor to drive the platform to move. Secondly, the longest edge size was measured by means of binarization algorithm and morphological interpolation algorithm. Thirdly, LabVIEW programming was used to control image picking and processing. Fourthly, the dimension or edge, average length value, 3σ, maximum/minimum value and difference value, comprehensive process capability index and so on were displayed through man-machine interface to confirm the product quality. The experimental results indicated that, 10 pieces of paper tape could be measured by the image detection system each time, while the time for each piece was 64 s. The maximum positioning error was 0.005 mm, and the maximum error percentage was 3.93%. When compared with the national standards, the position and length of the edge of paper tape found in the edge detection could be used as the basis for adjusting or replacing the mold. The image detection system can replace manual measurement, reduce the error of artificial measurement, save time and improve production efficiency. |
