Embodiment Construction

[0041] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0042] Such as figure 1 Shown, the mark quality defect detection method on the glass fuse tube product of the present invention comprises the following steps:

[0043] Acquire the original image of the glass fuse tube to be tested by the sensing unit, and send the collected original image to the image processing unit;

[0044] The image processing unit processes and analyzes the collected original image of the glass fuse tube to be tested, and detects the quality defects of the marks on the product, that is, the mark is not engraved, the position of the mark is on the top, the content of the marks at both ends is the same, and the mark does not meet the requirements, so as to distinguish The appearance quality of the glass fuse tube.

[0045] The method of the present invention passes through Figure 4 The device shown is realized, and the glass fuse tube melt qual...

Abstract

The invention relates to a method and a device for detecting quality defects of a mark on glass fuse tube products. The method comprises the following steps: collecting and acquiring an original image of a to-be-detected glass fuse tube through a sensing unit and sending the collected original image to an image processing unit; treating and analyzing the collected original image of the to-be-detected glass fuse tube by the image processing unit; detecting the quality defects of the marks on the products, namely, non-countermark, upward shifting mark position, identical mark contents at two ends and mark inconsistent to the requirement, thereby judging the appearance quality of the glass fuse tube. A low-angle loop illuminating method is adopted according to the invention, the online image collection for multiple defects of the glass fuse tube is realized, the image cutting and target identification are realized on the basis of regional image feature parameter method, the automatic and online detection for appearance quality defects of the glass fuse tube is realized, the detection speed and the detection precision are greatly increased and the reliability of the detection result is ensured.

Description

technical field [0001] The invention relates to the technical field of machine vision detection, in particular to a method and device for detecting quality defects of marks on glass fuse tube products based on machine vision. Background technique [0002] In all walks of life, glass fuse tubes are widely used in various circuits. The glass fuse tube is composed of copper cap, fusible body, glass tube and other parts. The copper cap is engraved with characters to indicate the product's logo status, and there are solder balls on the fusible body. At present, the inspection of the appearance quality of the glass fuse tube is mostly manual inspection. Because the glass fuse tube parts are small, it is not easy to clamp, and it needs to be observed while rotating. The detection speed is slow and the detection efficiency is low. Due to the fatigue and inconsistency of the inspector, visual inspection The consistency is poor, the fatigue of the human eye is easy to cause misjudgme...
