Online detection method for water ripples on arc surface

Abstract

The invention provides an online detection method for water ripples on an arc surface, and belongs to the technical field of online detection of packaging containers. The online detection method is completed through a light detection device, the light detection device comprises a grating plate, a first reflecting part, a second reflecting part, a light source and an image capturing terminal, the grating plate is provided with a plurality of shading areas and light transmitting areas which are distributed at intervals, the light source is located below the grating plate, the first reflecting part is located on the outer side of a to-be-detected face, and the second reflecting part is located on the inner side of the first reflecting part; after the light penetrating through the light-transmitting area is reflected by the to-be-detected surface, the first light reflecting part and the second light reflecting part in sequence, an image after being reflected by the second light reflecting part is acquired by the image capturing terminal; the judgment mode is that the black-and-white mutual doping condition in the obtained image is observed, the denser the black-and-white mutual doping is, the denser the water ripple distribution of the to-be-detected surface is, and the larger the black-and-white mutual doping amount is, the larger the water ripple size of the to-be-detected surface is. The method has the advantages of high efficiency, simple mode and the like.

Description

technical field [0001] The invention belongs to the technical field of on-line detection of packaging containers, and relates to an on-line detection method for water ripples on an arc surface. Background technique [0002] There are many arc-shaped objects that we often come into contact with, such as cylinders and cones are arcs. However, when the human eye observes the arc, there is only a narrow viewing angle that the human eye can accurately see, and the other viewing angles cannot effectively observe the details, such as scratches, due to the presence of arc scattering and reflection. The cylindrical glass bottles we usually use are arc-shaped. [0003] As a traditional packaging material, glass bottles are widely used in the fields of food and medicine mainly because glass has the characteristics of stable chemical properties, colorless, odorless, crystal clear and beautiful, and also has the advantages of acid resistance, cleaning resistance and pressure resistance....

AI Technical Summary

Problems solved by technology

[0006] Therefore, glass bottle manufacturers use a large number of manual light inspections to identify water ripples that are very difficult to observe and difficult to distinguish by human touch.

Nowadays, the high cost of labor, time-consuming management, laborious recruitment, emphasis on health and quality, and the continuous drop in the price of glass bottles will force manufacturers to order online testing equipment.

[0007] According to the feedback and detection effect of manual light inspection, it can only be detected manually one by one, and each bottle needs to be picked up by hand and rotated 360 degrees, which is inefficient and labor-intensive

In addition, artificial need to visually reflect the light, continuous visual will hurt the eyes

The water ripples can be seen manually manually, but the number, length, width and depth cannot be clearly seen visually, nor can the number of water ripples be quantified

There are pain points in manual light inspection
