Abstract

The invention discloses a dispensing quality detection method, which comprises the following steps: S1, collecting a standard qualified workpiece graph, and determining an edge groove on the basis ofa HALCON image analysis processing technology, wherein the edge groove refers to a glue area in a workpiece; s2, determining a glue overflowing area in the standard qualified workpiece graph by utilizing the obtained glue area; s3, creating a matching template by utilizing the standard qualified workpiece graph; s4, acquiring a to-be-detected workpiece graph, and matching the to-be-detected workpiece graph with the matching template created in the step S3; and S5, determining a dispensing quality detection result according to the matching result in the step S4. Through the dispensing quality detection method and device, the detection efficiency of the dispensing quality can be improved, and the labor cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of machine vision template matching, in particular to a dispensing quality detection method based on HALCON-based digital image analysis and processing technology. Background technique [0002] The dispensing process is widely used in various structural parts packaging and connection conditions. After the dispensing process is completed, the dispensing quality needs to be tested. Since the material is non-metal, its mechanical properties such as hardness and strength are much different from those of metal. A considerable part of the methods suitable for quality inspection after metal processing are not suitable for dispensing. The traditional dispensing quality inspection still relies on manual inspection to a large extent, that is, the dispensing quality inspection is completed through manual comparison. As a result, the quality inspection process has high cost, lower efficiency, and poor accuracy, and cannot ...
