Equipment features and layout

Light source: LED surface light source, with a life span of 30,000 hours, using the backlight illumination method, the edge contour of the object to be measured can be clearly outlined; in the image, the marked part is black, and the non-marked part is white, forming a "Black and white" images that are convenient for system analysis and processing.

Lens: Using manual aperture fixed focus lens, by adjusting the "focus adjustment ring" to make the image imaged on the CCD target surface the clearest, and by adjusting the "aperture adjustment ring", the brightness of the image is optimal.

Camera: The area array CCD analog camera is used, the resolution of the camera is 640*480 pixels, and the image acquisition speed can reach 80 frames/second.

Layout diagram: After the labeling machine, it is required to be on a single-segment chain path of more than 1500mm, the relative clearance of the bottle during the running process is more than 2cm, the relative jitters of the chain at the installation position is relatively small, and the guardrail is smooth
