Plastic Packaging - Visual Inspection Machine With Bottle Cap Image Display

Inspection standard

Inspection principle

The bottle cap inspection system is based on machine vision technology. It is an application of non-contact and non-damaging automatic detection technology in the detection of bottle cap defects. It is an effective means to realize automation, intelligence and precision control. It is safe, reliable, high speed and high Accuracy, simple and convenient operation, can work for a long time in harsh environments and other outstanding advantages.

The detection system obtains the surface image of the product through an appropriate light source and image sensor, uses the corresponding image processing algorithm to extract the feature information of the image, and then performs operations such as positioning, identification, grading, etc., statistics, and analysis of surface defects based on the feature information. So as to achieve the purpose of eliminating defective products, retaining good products, and improving the quality of bottle caps.

Vision solutions

The machine vision defect detection system converts the bottle cap into an image signal through an industrial camera, transmits it to the image software processing system, and converts it into a digital signal according to information such as pixel distribution and brightness. The image software processing system performs operations on these signals to extract the original bottle cap image features for judgment and comparison, and provides the bottle cap detection results in real time, correspondingly outputs ok and ng signals, automatically saves the detection data, and realizes intelligent detection.

The main items of inspection include: bottle cap damage detection, bottle cap height detection, bottle mouth defect visual detection, liquid level detection, bottle body labeling detection. Compared with traditional manual naked eye inspection, machine vision inspection has high precision, high efficiency, good continuity and can generate reports.

Feature of system
