A method for detecting the defects of soldering tabs of single-soldering tab lamp caps

Abstract

The invention discloses a method for detecting the defects of a single-solder lamp holder. On the matte background strip, the lamp head image is collected by a monocular industrial color camera with its own light source; then image segmentation is performed to separate the lamp head and the solder piece from the image; then element marking is performed on the binary image of the solder piece to determine whether If there is a solder chip missing defect, it is determined by the statistical threshold of the number of pixels in the binary image of the solder chip to determine whether there is a solder chip defect defect. The centroid of the lamp cap and the solder tab image are consistent to determine whether there is a solder tab dislocation defect. Compared with the prior art, the present invention can replace manual detection, has fast detection speed and high accuracy, improves work efficiency and brings considerable economic benefits.

Description

technical field [0001] The invention relates to the technical field of quality detection of lamp cap products, in particular to a method for detecting defects of soldering tabs of a single soldering tab lamp cap. Background technique [0002] The lamp base is the interface between the luminous body of the lamp and the power supply. As the main supporting part of the electric light source product, its quality inspection plays an important role in the production process of the electric light source, and directly determines the overall quality level of the lamp. At present, the quality inspection of lamp head products in our country mainly relies on human vision and subjective judgment ability to adopt manual random inspection or full inspection to ensure the quality of products, which takes up a lot of manpower, and the labor cost is getting higher and higher. Affected by factors such as personal vision, emotion, fatigue, light, etc., work efficiency is low and sorting differe...

At present, the quality inspection of lamp head products in our country mainly relies on human vision and subjective judgment ability to adopt manual random inspection or full inspection to ensure the quality of products, which takes up a lot of manpower, and the labor cost is getting higher and higher. Affected by personal vision, emotion, fatigue, light and other factors, the work efficiency is low and the sorting differences are large. This mode no longer meets the requirements of modern industrial production automation and has become a bottleneck for enterprises to improve efficiency and benefits.

The quality inspection of the lamp cap is mainly aimed at the detection of the defects of the solder tabs of the lamp cap. The defects of the solder tabs of the single solder tab lamp cap include missing solder tabs, defective solder tabs, overfilling, plugged holes of solder tabs and dislocation defects of solder tabs. These defects make the electric light source produced The product is unqualified and cannot be used. Therefore, it is urgent to study a new detection method to replace the traditional detection method and improve work efficiency.
