AI Technical Summary

Technical Problem

Existing GDX6 or GDX6S soft-pack cigarette packaging machines suffer from poor imaging and inaccurate detection during the inspection process, especially when the cigarette packs are running unstablely, causing defective cigarette packs to flow downstream and affecting quality.

Method used

The system employs a combination of PLC, image detection controller, encoder, camera light source strobe enhancement controller, and multiple cameras. By linking the encoder with the PLC, it achieves precise timing synchronization for taking pictures and controlling the light source, ensuring that all six sides of the cigarette pack can be stably photographed. Combined with light source strobe enhancement technology, it improves image quality.

Benefits of technology

It improves the imaging effect of cigarette packs and the accuracy of quality inspection, and can clearly capture images under high-speed operation, adapting to the needs of high-paced production and ensuring the accuracy of inspection.

Abstract

The utility model discloses a cigarette packet detection system based on a C800 small box transparent paper packaging machine. A first camera, a second camera, a third camera and a fourth camera of the system are electrically connected with an image detection controller respectively; the image detection controller, the encoder and the camera light source stroboscopic brightening controller are electrically connected with the PLC; the first camera is used for shooting the front surface, the left side surface and the rear surface of the cigarette packet; the second camera is used for shooting the lower surface of the cigarette packet; the third camera is used for shooting the right side of the cigarette packet; the fourth camera is used for shooting the upper surface of the cigarette packet; the included angle between the lens direction of the first camera and the front surface of the C800 small box transparent paper packaging machine is 45 degrees, and the included angle between the lens direction of the third camera and the front surface of the C800 small box transparent paper packaging machine is 80 degrees. According to the technical scheme, the imaging effect of all faces of a cigarette packet of the C800 small box transparent paper packaging machine can be improved, and the accuracy of cigarette packet packaging quality inspection is improved.
